Description

[Technical field]

[0001] The present invention relates to medical tracking systems, and more particularly to medical optical tracking systems. [Background technology]

[0002] In clinical surgery, the lumens of blood vessels, ureters, fallopian tubes, tracheas, etc. are generally wrapped in tissue, so surgeons must undergo long-term training and become familiar with the anatomical structures in order to accurately separate the lumens of blood vessels, ureters, fallopian tubes, tracheas, etc. Even experienced surgeons may accidentally damage the lumens of blood vessels, ureters, fallopian tubes, tracheas, etc., so a device is needed that can accurately mark the lumens of blood vessels, ureters, fallopian tubes, tracheas, etc. in tissue.

[0003] In addition, as the resolution of medical imaging equipment is greatly improved, some tumor tissues can be found in small volumes, such as lung nodules, uterine fibroids, esophageal tumors, liver tumors, etc. Because the volumes of these tumor tissues, such as lung nodules, are small, they are difficult to accurately identify when resected under laparoscopy, so it is necessary to mark the tumor tissue to be resected in order to facilitate laparoscopic surgical resection.

[0004] Additionally, since lymph node dissections are typically performed in close proximity to blood vessels, there is also a need to define the location and extent of blood vessels to facilitate laparoscopic surgery.

[0005] As described above, the conventional technology cannot mark blood vessels, ureters, fallopian tubes, vas deferens, trachea, etc. hidden in tissue with visible light, which is inconvenient for identification during laparoscopic surgery. Therefore, in order to facilitate identification of the internal cavities of blood vessels, ureters, fallopian tubes, vas deferens, trachea, etc. and solid tumors under laparoscopy, it is necessary to develop a visible light marking technology and device under laparoscopy.

[0006] The present invention discloses a technique and apparatus for marking lumens such as blood vessels, ureters, fallopian tubes, vas deferens, trachea, etc., and for defining solid tumors, based on visible light technology. Summary of the Invention

[0007] The present invention aims to solve the problem that blood vessels, tissues, organs or small tumors cannot be accurately marked under laparoscopy in traditional clinical surgery, and by adopting an optical tracking setting, in clinical surgery, by setting different color light sources, it can accurately identify the blood vessels, tissues or organs that need to be protected in clinical surgery, effectively avoid accidental damage during surgery, or effectively define small tumors, and facilitate the effective implementation of clinical surgery.

[0008] The medical optical tracking system of the present invention includes a light source 1 and an optical tracking carrier 2. A. The optical tracking carrier 2 includes a light-guiding material; B. The light emitted from the light source 1 is transmitted through the optical tracking carrier 2, and the optical tracking carrier 2 performs optical tracking.

[0009] The light source 1 and the optical tracking carrier 2 can be in direct contact with each other, and the light emitted from the light source 1 can be directly transmitted through the light-guiding material of the optical tracking carrier 2 for tracking. The light source 1 can also be in a non-contact form, and the light emitted from the light source 1 can be stored in an energy carrier in the optical tracking carrier 2, such as the light-storing self-luminous body 21-1, and then converted into energy to emit light for tracking. The light-emitting end 11-1 of the light source 1 can also be packaged integrally with the optical tracking carrier 2 and directly installed at the position where tracking is required.

[0010] The light source 1 is an LED light source 11, and / or a medical cold light source 12, and / or natural light. The light source 1 can be various light sources capable of emitting light rays, and the light rays emitted from the light source 1 can be tracked after being transmitted through the optical tracking carrier 1. Compared with general illumination light sources, the LED light source 11 has features such as a small volume, high luminous efficiency, and strong light source directivity, and in particular, in terms of safety, the LED light source has an advantage that cannot be compared with general light sources. First, the LED light source is a low-voltage DC power source, and the power supply voltage only needs to be 6 to 24 V; second, the LED light source does not contain mercury, and does not cause damage such as poisoning to the human body; and more importantly, the LED light source is a cold light source, does not generate a large amount of heat during operation, is safe to touch, and does not cause unexpected high-temperature burns to the human body. The medical cold light source 12 is a general light source during conventional surgery, and can be placed after the light source 1, which is easy to obtain in the operating room and does not require additional equipment.

[0011] The color of the light emitted from the light source 1 can be set according to the background color or the transmission requirements. Through the setting of the light, in clinical operation, the doctor can directly see the location of the optical tracking carrier 2 through the tissue with the naked eye, and can accurately identify the blood vessels, tissues or organs that need to be protected in clinical operation, so as to effectively avoid accidental damage during operation. The light emitted from the light source 1 can be set according to the background color or the tissue that needs to be transmitted in the body cavity. When it is necessary to transmit the tissue, red and yellow are preferred, followed by purple and white, and when it is necessary to display the vascular tissue, the light is preferably green.

[0012] The light source 1 emits blinking light. The light source 1 can be further set to be intermittently lit, blinking, or the like, as required.

[0013] The intensity of the light emitted from the light source 1 is configurable. The intensity of the light emitted from the light source 1 can also be adjusted as needed to accommodate different clinical environments. The illuminance of the light emitted from the light source 1 is usually 5000 lux to 150000 lux.

[0014] The light source 1 includes a control system 13 including a wavelength adjustment mechanism 13-1 and a light intensity adjustment mechanism 13-2, where the wavelength adjustment mechanism 13-1 can adjust the color of the emitted light by adjusting the wavelength, and the light intensity adjustment mechanism 13-2 can adjust the illuminance of the emitted light.

[0015] The LED light source 11 is installed inside and / or outside the body. Since the volume of the light emitting end 11-1 of the LED light source 11 can be very small, the LED light source 11 can be installed outside the body and transmit light into the human body through the optical tracking carrier 2, but can also be installed directly inside the human body, the outside is covered with the optical tracking carrier 2, and the LED light source 11 can be installed directly on the part that needs tracking.

[0016] The light source 1 and the optical tracking carrier 2 are connected without contact or are connected in contact. The light source 1 may be connected to the optical tracking carrier 2 through the light-guiding connector 26 to provide a light source, or may be irradiated to the optical tracking carrier 2 such as the light-storing self-luminous tracking carrier 21 without contact, and the tracking of the optical tracking carrier 2 is realized by storing and converting light energy.

[0017] The LED light source 11 and the optical tracking carrier 2 are contact-connected, and the LED light source 11 is installed in the optical tracking carrier 2. The optical tracking carrier 2 is directly wrapped around the outside of the LED light source 11, and the LED light source 11 and the optical tracking carrier 2 are set in the human body to track internal cavities, organs, tumors, etc.

[0018] The optical tracking carrier 2 is a phosphorescent spontaneous light tracking carrier 21. The spontaneous light material refers to a material that can absorb energy in a certain way and convert it into non-equilibrium light radiation, and the process of converting the energy absorbed inside the material into non-equilibrium light radiation is the luminous process. In particular, the phosphorescent spontaneous light material can continue to emit light for more than 12 hours in a dark environment after several minutes or tens of minutes under the action of external lighting, which can meet the tracking needs of most surgical procedures. The phosphorescent spontaneous light tracking carrier 21 can directly absorb the energy of the lamp in the operating room, so that various external lights can all be the light source 1, and there is no need to directly connect to the light source 1, and the use process is very simple.

[0019] The light-storing self-luminous tracking carrier 21 includes a light-storing self-luminous body 21-1 and a protective carrier 21-2.

[0020] The protective carrier 21-2 is made of a transparent light-guiding material, and the light-storing spontaneous light-emitting body 21-1 is provided by being sealed within the protective carrier 21-2.

[0021] The light-storage self-illuminating body 21-1 can absorb and convert external energy to emit light. The protective carrier 21-2 is made of transparent medical materials and can directly contact tissue, so that the light emitted by the energy conversion of the light-storage self-illuminating body 21-1 can be effectively transmitted and effectively tracked, and biological safety is also guaranteed in clinical use. The light-storage self-illuminating body 21-1 can be installed at different positions and designed in different shapes to perform fixed-point tracking or overall tracking as needed.

[0022] The optical tracking carrier 2 is a light-guiding optical fiber 22. The light-guiding optical fiber 22 has a good light-guiding effect, can transmit light to different positions as needed, and can be connected or disconnected as needed, which is very convenient for clinical use.

[0023] The optical tracking carrier 2 includes at least one of the light-guiding optical fibers 22 .

[0024] The end and / or side of the light-guiding optical fiber 22 can be illuminated. The light-guiding optical fiber 22 can be illuminated not only at its end but also at its side, and the light-guiding optical fiber 22 can be lit up as a whole to emit light.

[0025] The optical tracking carrier 2 is a combination of a plurality of the light-guiding optical fibers 22 .

[0026] The optical tracking carrier 2 may be composed of a single light-guiding optical fiber 22, or may be a combination of multiple light-guiding optical fibers 22, and may be in various forms, such as forming an optical fiber bundle, weaving it into a mesh shape, and arranging it at different lengths.

[0027] The light-guiding optical fiber 22 has a smooth surface. When the light-guiding optical fiber 22 has a smooth surface, due to the good light-guiding performance of the light-guiding optical fiber 22, the light exit port 22-2 of the light-guiding optical fiber 22 is located at the distal end of the light-guiding optical fiber 22, and fixed-point tracking can be realized.

[0028] The light-guiding optical fiber 22 has a non-smooth surface 22-1.

[0029] The non-smooth surface 22-1 is a non-smooth surface 22-11 that can form reflection and / or scattering, and the non-smooth surface 22-1 can realize the overall illumination of the non-smooth surface 22-1 through the reflection and / or scattering of light, and achieve the effect of overall tracking.

[0030] Light outlets 22-2 are provided intermittently on the light-guiding optical fiber 22. Each of the intermittently provided light outlets 22-2 has a light conducting surface 22-21 and a reflecting surface 22-22, and the light is conducted through the conducting surface 22-21 and is reflected when it reaches the reflecting surface 22-22 and is output from the light outlet 22-2 to form a tracking point, and a plurality of the light outlets 22-2 can form a chain-like tracking band.

[0031] The light outlet 22-2 is a non-axial light outlet 22-21, which is provided on a side of the light-guiding optical fiber 22 along the length direction of the light-guiding optical fiber 22. When the light outlet 22-2 is provided completely along the length direction of the light-guiding optical fiber 22, the entire light-guiding optical fiber 22 can be illuminated along the length direction of the light-guiding optical fiber 22, and the entire tracking of the light-guiding optical fiber 22 can be realized.

[0032] Due to the regular arrangement of the light exit ports 22-2, the light exit ports 22-2 can mark the length size of the light-guiding optical fibers 22.

[0033] Due to the regular arrangement of the distribution density of the light exit ports 22-2, the intensity of the scattered light varies, and the length size of the light-guiding optical fiber 22 is marked.

[0034] When the light outlets 22-2 are closely arranged, the emitted light will be stronger and the visual effect will be brighter; when the light outlets 22-2 are sparsely arranged, the emitted light will be weaker and the visual effect will be darker. By combining light and dark in this manner, a visual effect similar to that of a ruler can be formed, and the effect of size marking can be achieved while being tracked.

[0035] The light-guiding optical fibers 22 are woven in a mesh-like shape, and the light exits 22-2 are scattered at different positions. When the light-guiding optical fibers 22 are woven in a mesh-like shape, the lengths of the light-guiding optical fibers 22 are set separately, and the light exits 22-2 of the light-guiding optical fibers 22 are also differentiated and scattered accordingly, so that the overall tracking of the three-dimensional space can be realized. Since it is not necessary to provide the light exits 22-1 in the middle of each of the light-guiding optical fibers 22, the light transmission effect is better, and the visual effect of a single tracking point is very bright. The light exits 22-2 are provided on the sides, and the light-guiding optical fibers 22 that can be lit as a whole can be woven in a mesh-like shape to realize the tracking of the entire area of ​​the entire cavity. In addition, the mesh-like shape can have good support, and is particularly suitable for supporting and tracking large cavities such as the bladder and uterus.

[0036] In clinical applications, the optical tracking carrier 2 may be set in each location that requires tracking as needed, such as each internal cavity of the ureter, vas deferens, fallopian tube, etc., or in solid tumors such as uterine fibroids, lung tumors (especially lung nodules), liver tumors, etc., and may even be set in blood vessels, and in particular, by utilizing the feature that the light-guiding optical fiber 2 can emit light from the side to realize overall tracking, each internal cavity, blood vessel, solid tumor, etc. can be marked.

[0037] The medical optical tracking system 500 includes a coating 3 on its surface.

[0038] Said coating 3 is an anticoagulant coating, and / or a hydrophilic coating, and / or a hydrophobic coating.

[0039] The coating 3 can be designed to have different properties as needed, for example, when the light-guiding optical fiber 22 needs to enter a blood vessel, the coating 3 can be designed as an anticoagulant coating, and when the light-guiding optical fiber 22 needs to enter various cavities, the coating 3 can be designed as a hydrophilic coating or a hydrophobic coating as needed.

[0040] The optical tracking carrier 2 includes a delivery unit 23. The delivery unit 23 can deliver the working unit 2-1 of the optical fiber tracking carrier 2 to the part that needs tracking, such as blood vessel, cavity, tumor operation site, etc., as needed.

[0041] The delivery portion 23 is movably mounted on the optical tracking carrier 2. In clinical applications, the delivery portion 23 can be detached from the optical tracking carrier 2 or moved relative to the optical tracking carrier 2 as required.

[0042] The medical optical tracking system 500 further includes a developing mechanism 4 .

[0043] The developing mechanism 4 is made of metal and has a thermal conduction function, which can prevent the medical optical tracking system 500 from being accidentally damaged due to the temperature of the part of the medical optical tracking system 500 that is inserted into the human body being too high, and the temperature is normally controlled to be below 37°C.

[0044] The developing mechanism 4 is a developing line 41, and / or a developing ring 42, and / or a developing block 43. The applicant only gives examples of some of the above-mentioned developing methods, but in practical applications, those skilled in the art can design different developing methods according to needs, and the applicant does not give examples of them one by one here, but all of them are within the scope of protection of the present application.

[0045] The developing mechanism 4 develops with X-ray, and / or MRI, and / or B ultrasound. The developing mechanism 4 can develop and present scenes such as X-ray, magnetic navigation, or B ultrasound, making it easy to set the optical tracking carrier 2 in an observation or navigational situation, and is particularly suitable for setting on important blood vessels, solid tumors, etc.

[0046] The medical optical tracking system 500 further includes a protective sleeve 5. The optical tracking carrier 2, the developing mechanism 4, etc. may be provided within the protective sleeve 5. The coating 3 may be provided on the outside of the protective sleeve 5 as required.

[0047] The protective sleeve 5 is made of a transparent material, and the optical tracking carrier 2 is placed in the protective sleeve 5. The protective sleeve 5 is made of a medical transparent material, which can protect the optical tracking carrier 2, and the transparent material can still ensure the tracking effect of the optical tracking carrier 2.

[0048] The optical tracking carrier 2 includes a channel 24 therein. The channel 24 may be used as a surgical instrument channel, a bodily fluid drainage channel, or the like, as desired.

[0049] The optical tracking carrier 2 is made of flexible medical materials and can move along the cavities such as blood vessels, ureters, esophagus, trachea, fallopian tubes, spermatic ducts, etc. The optical tracking carrier 2 has good flexibility and can move along the blood vessels or cavities, so that it can be set in different positions according to needs.

[0050] The optical tracking carrier 2 includes a shaping mechanism 25. The shaping mechanism 25 can shape the optical tracking carrier 2, for example, into various shapes such as circle, arc, sphere, etc. as required to meet different tracking needs.

[0051] The shaping mechanism 25 is a shape-memory shaping mechanism 25-1. The shape-memory shaping mechanism 25-1 has a simple structure such as a line or stripe at room temperature for easy setting, and returns to the set shape under the action of body temperature after entering the human body.

[0052] The shape memory shaping mechanism 25-1 is made of a shape memory metal wire woven and / or carved from a shape memory metal tube or sheet. The shape memory shaping mechanism 25-1 may be woven into a desired shape with a shape memory metal wire, or may be directly carved into a desired shape using a shape memory alloy tube or a shape memory alloy sheet.

The medical catheter 900 with tracking device includes at least one interface 900-2, the interface 900-2 being provided at a proximal end 900-12 of the catheter 900-1; C. The optical tracking carrier 2 of the medical optical tracking system 500 is mounted on the catheter 900-1 to mark the location of the catheter 900-1.

[0055] The medical catheter 900 with a tracking device includes a developing mechanism 4. The developing mechanism 4 is installed in the catheter 900-1, and the developing mechanism 4 can perform developing presentation in scenes such as X-ray, magnetic navigation, or B ultrasound, and facilitate the setting of the catheter 900-1. The developing mechanism 4 can be made of metal material and has a heat conduction function, which can prevent the temperature in the body from being too high due to the LED light source 11, and the temperature should usually be controlled within 37°C.

[0056] The catheter 900-1 is provided with the optical tracking carrier 2, which can provide local or global tracking for the catheter 900-1 as required.

[0057] The catheter 900-1 is made of a transparent material and constitutes the optical tracking carrier 2, and the light source of the medical optical tracking system 500 is an LED light source 11, and the light emitting end 11-1 of the LED light source 11 is installed in the tube wall of the catheter 900-1 to track the catheter 900-1. The LED light source 11 includes a small volume light emitting end 11-1, and generally, the light emitting end 11-1 is an LED lamp whose size is controlled to be 2mm or less, for example, whose package size is between 0.2mm and 0.5mm, and the light emitting end 11-1 is directly installed in the tube wall of the catheter 900-1 and connected to a power source via a circuit system 11-2, so as to emit light in the tube wall of the catheter 900-1.

[0058] The light emitting end 11-1 of the LED light source 11 is provided at the distal end 900-11 of the catheter 900-1 and tracks the distal end 900-11 of the catheter 900-1.

[0059] The light emitting ends 11-1 of the LED light sources 11 are distributed within the tube wall of the catheter 1 to form an LED lamp strip or an LED lamp network, and perform overall tracking for the catheter 900-1.

[0060] The light-emitting end 11-1 may be provided at any position of the catheter 900-1 as necessary. When provided at the distal end, it can track the distal end 900-11 of the catheter 900-1, and when provided in the middle of the catheter 900-1, it can track the local central portion of the catheter 900-1. When the circuit system 11-2 employs a flexible circuit board 11-21, the light-emitting end 11-1 can be provided in a distributed manner at any position of the flexible circuit board 11-21 to realize partial or total tracking of the catheter 900-1.

[0061] The optical tracking carrier 2 of the medical optical tracking system 500 is a light-guiding optical fiber 22, and a light-guiding connector 26 is connected to the proximal end of the light-guiding optical fiber 22. The light-guiding optical fiber 22 is arranged along the length of the catheter 900-1 and tracks the catheter 900-1.

[0062] The light-guiding optical fiber 22 has a smooth surface, and a light exit port 22-2 is provided at the distal end of the catheter 1 and tracks the distal end 900-11 of the catheter 900-1.

[0063] The light-guiding optical fiber 22 has a non-smooth surface 22-1 and a light exit port 22-2 on the side thereof, and provides global tracking for the catheter 900-1.

[0064] The light-guiding optical fiber 22 can perform fixed-point tracking of the distal end 900-11 of the catheter 900-1, and can also perform linear tracking of the catheter 900-1 along the length direction by using the light exit port 22-2 on the side. Furthermore, by weaving the light-guiding optical fiber 22 into a mesh-like shape, it can also perform global tracking of the catheter 900-1. Furthermore, by weaving the light-guiding optical fiber 22 into a mesh-like shape, the elastic supporting force of the light-guiding optical fiber 22 can be utilized to further support the tubular wall of the catheter 900-1.

[0065] The outer surface of the catheter 900-1 may further be provided with a coating 3, such as a hydrophilic coating, if desired.

[0066] The medical catheter 900 with a tracking device is a medical gastric tube 901, a medical urethral catheter 902, a medical vas deferens, a medical fallopian tube, or a medical trachea. The applicant only lists some of the above-mentioned use scenarios of the medical catheter 900 with a tracking device, but in actual application, the medical catheter 900 with a tracking device may be designed as required structures for different application scenarios according to clinical needs.

[0067] The medical catheter with tracking device 900 is a medical gastric tube 901 including a catheter 900-1, one interface 900-2, and a medical optical tracking system 500, in which a working opening 900-11-1 is provided at the distal end 900-11 of the catheter 900-1, and the medical optical tracking system 500 tracks the catheter 900-1.

[0068] The medical gastric tube 901 enters the stomach through the esophagus and is an artificial delivery channel for food, and the interface 900-2 can be externally connected to a food injection device. In clinical surgery, it may be necessary to grasp and observe the position of the distal end 900-11 of the catheter 900-1, in which case the medical optical tracking system 500 only needs to perform local tracking of the distal end of the medical gastric tube 901. In other cases, such as when performing surgery along the esophagus, it is necessary to perform global tracking of the medical gastric tube 901 to prevent accidental damage to the esophagus.

[0069] When it is necessary to perform local tracking of the distal end of the medical gastric tube 901, a technical solution may be adopted in which the light emitting end 11-1 of the LED light source 11 is individually or collectively provided at the distal end of the catheter 900-1 for tracking, or the light guiding optical fiber 22 having a smooth surface may be used, which may be a single light guiding optical fiber 22 or a light guiding bundle consisting of a plurality of light guiding optical fibers 22, and the distal end of the catheter 900-1 is tracked using the light emission port 22-1 at the end, or the light guiding optical fibers 22 are arranged circumferentially along the side wall of the catheter 900-1 to form a halo at the distal end of the catheter 900-1, thereby performing local tracking of the distal end of the catheter 900-1.

[0072] The medical optical tracking system 500 can perform fixed point tracking on the medical urinary catheter 902 and can also perform large range or overall tracking on the medical urinary catheter 902 .

[0073] For example, when it is necessary to perform fixed-point or small-range local tracking of the working end of the medical urethral catheter 902, a technical solution may be adopted in which the light-emitting end 11-1 of the LED light source 11 is individually or collectively arranged at the distal end of the catheter 900-1 for tracking; the light-guiding optical fiber 22 having a smooth surface may be adopted, and may be a single light-guiding optical fiber 22 or a light-guiding bundle consisting of a plurality of light-guiding optical fibers 22, and the light emission port 22-1 at the end may be used to track the distal end of the catheter 900-1; or the light-guiding optical fibers 22 may be arranged circumferentially along the side wall of the catheter 900-1 to form a halo at the distal end of the catheter 900-1, and local tracking of the distal end of the catheter 900-1 may be performed.

[0074] For example, when it is necessary to perform local tracking of the bladder or global tracking of the catheter 900-1, the light emitting ends 11-1 of the LED light sources 11 may be distributed in the wall of the catheter 900-1 to form a light guide strip or a light guide network to perform global or large-area tracking of the catheter 900-1. A light guide optical fiber 22 having a non-smooth surface 22-1 may be provided along the length of the wall of the catheter 900-1 to form a light guide strip to track the catheter 900-1 in the length direction, or the light guide optical fiber 22 may be woven in a mesh pattern to perform global tracking of the outer circumference of the balloon 900-13.

[0075] The medical urethral catheter 902 is a double-lumen urethral catheter 902-1, and a balloon 900-13 is provided at a distal end 900-11 of a catheter 900-1 of the double-lumen urethral catheter 902-1. The catheter 900-1 is provided with two lumens 1-1, and each lumen 1-1 is provided with one of the interfaces 900-2 corresponding thereto. One of the lumens 1-1 is a urinary catheter lumen 900- 14, the working opening 900-11-1 is provided at the distal end of the catheterization lumen 900-14, the interface 900-2 provided at the proximal end forms a drainage port 900-21, the other lumen 1-1 forms a water infusion lumen 900-15, the distal end of the water infusion lumen 900-15 is connected to the balloon 900-13, and the interface 900-2 connected to the proximal end forms a water infusion port 900-22.

[0076] In order to meet the time requirements of clinical surgery, the medical urethral catheter 902 used during surgery generally needs to be provided with the balloon 900-13, and water can be injected into the balloon 900-13 from the water inlet 900-22 through the water inlet lumen 15 to form a water bag, which can ensure the effective fixation of the medical urethral catheter 902 in the bladder and prevent it from falling off.

[0077] The medical urethral catheter 902 is a triple lumen urethral catheter 902-2, and a balloon 900-13 is provided at a distal end 900-11 of a catheter 900-1 of the triple lumen urethral catheter 902-2.

[0079] The solid tumor tracking device of the present invention includes the medical optical tracking system 500.

[0080] The solid tumor tracking device 910 includes a developing mechanism 4. The developing mechanism 4 may be configured by the displacement prevention mechanism 910-1 made of metal material, or may be provided separately, and the developing mechanism 4 can mark the location of the optical tracking carrier 2 under the condition of X-ray, MRI, or B ultrasound.

[0081] The solid tumor tracking device 910 includes a displacement prevention mechanism 910-1 and the medical optical tracking system 500, and the optical tracking carrier 2 of the medical optical tracking system 500 is mounted on the displacement prevention mechanism 910-1 and tracks the displacement prevention mechanism 910-1.

[0082] The anti-slip mechanism 910-1 can be fixed to the solid tumor that needs to be defined to prevent the solid tumor tracking device 910 from shifting due to human body movements such as respiratory movement of the lungs, peristalsis of the intestines, and peristalsis of the stomach.

[0083] In clinical applications, under X-ray or MRI conditions, a medical puncture needle is used to puncture a solid tumor that needs to be marked, and then the anti-displacement mechanism 910-1 is delivered to the location of the solid tumor and fixed to the solid tumor, and the optical tracking carrier 2 is provided on the anti-displacement mechanism 910-1 to position the anti-displacement mechanism 910-1. In this way, during surgery, the location of the solid tumor can be intuitively observed with the naked eye under the guidance of light.

[0084] The displacement prevention mechanism 910-1 has a hook-shaped structure, and / or a horn-shaped structure, and / or a dumbbell-shaped structure, and / or a coil spring-shaped structure, and / or a nail-shaped structure. Although the applicant has only given examples of the displacement prevention mechanism 910-1 having the above-mentioned structures, in actual applications, those skilled in the art can design the displacement prevention mechanism 910-1 having different structures as needed, and although the applicant will not give examples one by one here, all of them shall be within the scope of protection of the present application.

[0085] The anti-slip mechanism 910-1 has a hook-like structure, and includes at least one positioning hook 910-11. Usually, the anti-slip mechanism 910-1 includes two or three positioning hooks 910-11, so as to better prevent the anti-slip mechanism 910-1 from being displaced due to human body movements such as lung breathing, intestinal peristalsis, etc.

[0086] The optical tracking carrier 2 is a light-guiding optical fiber 22, a light-guiding connector 26 is connected to the proximal end of the light-guiding optical fiber 22, the distal end of the light-guiding optical fiber 22 is connected or fixed to the positional deviation prevention mechanism 910-1, and the light emission port 22-2 of the light-guiding optical fiber 22 is provided in the positional deviation prevention mechanism 910-1 and tracks the positional deviation prevention mechanism 910-1.

[0087] Due to its flexibility, the light-guiding optical fiber 22 can be directly wound, connected and fixed to the anti-shift mechanism 910-1, particularly the positioning hook 910-11, and optical tracking is performed on the anti-shift mechanism 910-1 using the light beam emitted from the light exit port 22-2 of the light-guiding optical fiber 22.

[0088] The light-guiding optical fiber 22 has a non-smooth surface 22-1, a light exit port 22-2 is provided on the side of the light-guiding optical fiber 22, and the light-guiding optical fiber 22 performs overall tracking with respect to the displacement prevention mechanism 910-1.

[0089] The light-guiding optical fiber 22 is made of a flexible medical material and is connected and fixed to the displacement prevention mechanism 910-1, and when the displacement prevention mechanism 910-1 is deformed, the light-guiding optical fiber 22 is deformed along with the displacement prevention mechanism 910-1. Since the light-guiding optical fiber 22 can be turned on as a whole, when the light-guiding optical fiber 22 is wound around the displacement prevention mechanism 910-1, particularly the positioning hook 910-11, it can be deformed along with the displacement prevention mechanism 910-1. In particular, when the displacement prevention mechanism 910-1 is made of a shape memory alloy, the shape of the light-guiding optical fiber 22 also changes as the shape of the displacement prevention mechanism 910-1 changes, ensuring the tracking effect of the displacement prevention mechanism 910-1.

[0090] The solid tumor tracking device 910 includes a displacement prevention mechanism 910-1, a delivery mechanism 910-2 and the medical optical tracking system 500, and the optical tracking carrier 2 of the medical optical tracking system 500 is mounted on the displacement prevention mechanism 910-1 and tracks the displacement prevention mechanism 910-1.

[0091] The delivery mechanism 910-2 includes a delivery sheath 910-21 and a pushing mechanism 910-22, the anti-misalignment mechanism 910-1 is disposed within the delivery sheath 910-21, and the pushing mechanism 910-22 can push the anti-misalignment mechanism 910-1 out of the delivery sheath 910-21.

[0092] The extrusion mechanism 910-22 may be fixedly connected to the displacement prevention mechanism 910-1 and remain in the body together with the displacement prevention mechanism 910-1 after the displacement prevention mechanism 910-1 is pushed out of the delivery sheath 910-21, or may be detachably connected to the displacement prevention mechanism 910-1 and, after the displacement prevention mechanism 910-1 is pushed out of the delivery sheath 910-21, the connection with the displacement prevention mechanism 910-1 is released and only the displacement prevention mechanism 910-1 is left in the solid tumor.

[0093] In clinical applications, the delivery mechanism 910-2 delivers the anti-slip mechanism 910-1 to the location of a solid tumor under X-ray or MRI conditions and fixes it to the solid tumor, and the optical tracking carrier 2 is mounted on the anti-slip mechanism 910-1 to position the anti-slip mechanism 910-1, so that during surgery, the location of the solid tumor can be intuitively observed with the naked eye under the guidance of light.

[0094] The light source 1 of the medical optical tracking system 500 is an LED light source 11, the optical tracking carrier 2 is made of a transparent material, and the light emitting end 11-1 of the LED light source 11 is provided on the optical tracking carrier 2 and provided on the position shift prevention mechanism 910-1 together with the optical tracking carrier 2 to track the position shift prevention mechanism 910-1.

[0095] When the light source 1 adopts the LED light source 11, the light emitting end 11-1 of the LED light source 11 can be integrally packaged with the optical tracking carrier 2 and integrally installed at a position where tracking is required by the anti-shift mechanism 910-1, and the light emitted from the light emitting end 11-1 is transmitted through the light-guiding material of the optical tracking carrier 2 and then displayed, and used to clinically identify the location of solid tumors.

[0097] The circuit system 11-2 is a flexible circuit board 11-21, and the light emitting end 11-1 of the LED light source 11 is distributed on the flexible circuit board 11-21 and packaged in the optical tracking carrier 2 to form an LED lamp strip, an LED lamp network, or an LED lamp ball, which is mounted on the anti-shift mechanism 910-1 and tracks the anti-shift mechanism 910-1.

[0098] The LED light source 11 may be tracked at a fixed point after packaging the single light emitting end 11-1. A flexible circuit board 11-21 may be adopted as the circuit system 11-2, and the light emitting end 11-1 may be distributed at any position on the flexible circuit board 11-21 to form a light emitting strip, and the light emitting strip may be wound around the displacement prevention mechanism 910-1. Alternatively, a plurality of the LED light sources 11 may be packaged together with the optical tracking carrier 2 in a mesh-like, spherical or other shape to perform overall tracking on the displacement prevention mechanism 910-1.

[0099] The light emitting end 11-1 of the LED light source 11 is provided on the positional deviation prevention mechanism 910-1, and its exterior is covered by the optical tracking carrier 2 made of a transparent material, and the light emitted from the light emitting end 11-1 tracks the positional deviation prevention mechanism 910-1.

[0100] The light emitting ends 11-1 are provided in a distributed manner on the displacement prevention mechanism 910-1 and perform overall tracking with respect to the displacement prevention mechanism 910-1.

[0101] The light emitting end 11-1 can be directly mounted on the anti-shift mechanism 910-1 and its exterior can be covered by the optical tracking carrier 2 made of a transparent material, in this way the light emitting end 11-1 can be perfectly attached to the exterior contour of the anti-shift mechanism 910-1 and can perform tracking for any shape of the anti-shift mechanism 910-1.

[0102] In addition, the light-emitting end 11-1 is arranged symmetrically and its exterior is covered by the optical tracking carrier 2, and the internal support of the light-emitting end 11-1 and the circuit system 11-2 and the volume of the light-emitting end 11-1 itself can be used to form the position shift prevention mechanism 910-1, so that the medical optical tracking system 500 can simultaneously perform the tracking function and the positioning function of the position shift prevention mechanism 910-1.

[0103] The circuit system 11-2 is a flexible circuit board 11-21, the optical tracking carrier 2 is made of a flexible transparent material, the light emitting end 11-1, the flexible circuit board 11-21 and the developing mechanism 4 are arranged together in the optical tracking carrier 2, and are arranged in the displacement prevention mechanism 910-1, when the displacement prevention mechanism 910-1 is deformed, the light emitting end 11-1, the flexible circuit board 11-21 and the developing mechanism 4 are deformed together with the optical tracking carrier 2 and the displacement prevention mechanism 910-1. In particular, when the displacement prevention mechanism 910-1 is made of a shape memory alloy, with the shape of the displacement prevention mechanism 910-1 changing, the shape of the flexible circuit board 11-21 also changes, ensuring the tracking effect of the displacement prevention mechanism 910-1.

[0104] The blood vessel tracking device of the present invention includes the medical optical tracking system 500.

[0105] The medical optical tracking system 500 can perform overall tracking for the blood vessel tracking device 920. In clinical use, under the action of the medical optical tracking system 500, when approaching a tracked blood vessel, the light emitted from the light source 1 can be seen penetrating the blood vessel through tissue, and the illuminance of the light emitted from the light source 1 ensures that the tracked blood vessel can be clearly seen when the distance from the blood vessel wall is about 0-30 mm.

[0106] The blood vessel tracking device 920 includes a developing mechanism 4. The developing mechanism 4 can perform developing presentations in scenes such as X-ray, magnetic navigation, or B ultrasound, and facilitates the setting of the catheter 900-1. The developing mechanism 4 can be made of metal material and has a heat conduction function, which can prevent the temperature of the LED light source 11 from being too high in the body, and the temperature should normally be controlled within 37°C.

[0107] The vessel tracker 920 includes coating 3, which is an anticoagulant coating.

[0108] The vascular tracking device 920 includes a delivery end 920-1, a guidewire 920-2, a protective sleeve 5 and the medical optical tracking system 500, the medical optical tracking system 500 and the guidewire 920-2 are arranged in the protective sleeve 5, and the outside of the protective sleeve 5 has a coating 3 which is an anticoagulant coating, the guidewire 920-2 is made of a metal material, can be developed by X-rays, can constitute a development mechanism 4, and has a heat conduction function, and the delivery end 920-1 can deliver the vascular tracking device 920 to a position where vascular tracking is required.

[0109] Since the blood vessel tracking device 920 includes a guide wire 920-2, the blood vessel tracking device 920 can be directly developed by X-ray, and the guide wire 920-2 is made of metal material, has a certain strength, and can be easily delivered, so the blood vessel tracking device 920 does not need to operate in cooperation with a separate medical guide wire. The coating 3 adopts an anticoagulant coating, which can ensure that the blood vessel tracking device 920 is safely located in the blood vessel that needs tracking during surgery. The heat conduction function of the guide wire 920-2 at the same time can prevent the temperature from being too high due to the LED light source 11 in the body, and the temperature should usually be controlled within 37°C.

[0110] The guidewire 920-2 is made of a shape memory alloy and shapes the distal end of the vessel tracker 920, constituting a shaping mechanism 25. The guidewire 920-2 can shape the distal end of the vessel tracker 920 as needed to accommodate the radian of the vessel, making the delivery process easier.

[0111] The medical optical tracking system 500 is provided with a channel 24 that constitutes a guidewire operation hole 920-3. A separate medical guidewire can be inserted into the guidewire operation hole 920-3 to perform a delivery operation together, and the structure of the medical optical tracking system 500 is simple.

[0112] The side wall of the optical tracking carrier 2 is made of transparent material, and a light guiding optical fiber 22 is provided in the side wall, the light guiding optical fiber 22 has a non-smooth surface 22-1, and a light outlet 22-2 is provided on the side along the length direction, and a coating 3, which is an anticoagulant coating, is provided on the outer surface of the optical tracking carrier 2, and the proximal end of the light guiding optical fiber 22 is connected to a light guiding connector 26, and under the action of the light emitted from the light source 1, the light guiding optical fiber 22 can emit light as a whole and track blood vessels. The light guiding optical fiber 22 has a simple structure and a small size, which is suitable for tracking small blood vessels.

[0113] The light source 1 is a medical cold light source 12. The medical cold light source 12 will not cause the temperature of the optical tracking carrier 2 installed inside the body to rise, making the blood vessel tracking process safer.

[0114] The side wall of the optical tracking carrier 2 is made of transparent material, the light source 1 is an LED light source 11, and the light emitting ends 11-1 of the LED light source 11 are distributed in the side wall of the optical tracking carrier 2 to form an LED lamp strip or an LED lamp network for tracking blood vessels. The LED light source 11 directly tracks blood vessels, has good lighting effect, and has a very good effect on tracking large blood vessels.

[0115] In clinical use, under an X-ray environment, using the technology of vascular interventional therapy, the vascular tracking device 920 is set at the position where tracking is required, and the power is turned on. Under the action of the light source 1, the optical fiber tracking carrier 2 works to emit visible light and track the blood vessel. During surgery, when approaching the blood vessel to be tracked, the light emitted from the light source 1 can be seen penetrating the blood vessel through the tissue, and the illuminance of the light emitted from the light source 1 ensures that the tracked blood vessel can be clearly seen when the distance from the blood vessel wall is about 0-30 mm.

[0116] The medical optical tracking system of the present invention includes a light source 1 and an optical tracking carrier 2. The optical tracking carrier 2 includes a light-guiding material. The light emitted from the light source 1 is transmitted through the optical tracking carrier 2, and then optically tracks the optical tracking carrier 2. The light source 1 may adopt the miniature LED light source 11, and the light-emitting end 11-1 of the LED light source 11 is directly integrated with the optical tracking carrier 2 and set in the human body to perform optical tracking. The medical optical tracking system of the present invention can be installed in the medical catheter with tracking device 900, the solid tumor tracking device 910, or the blood vessel tracking device 920 as required, and in clinical surgery, the setting of different color light sources can accurately identify the blood vessels, lumen, tissues, or organs that should be protected in clinical surgery, effectively avoiding accidental damage during surgery, or effectively defining small tumors, facilitating the effective implementation of clinical surgery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0118] Example 1: Medical Optical Tracking System of the Present Invention 1 to 13, the medical optical tracking system of this embodiment includes a light source 1 and an optical tracking carrier 2. As shown in FIG.

[0119] The optical tracking carrier 2 includes a light-guiding material, and the light emitted from the light source 1 is transmitted through the optical tracking carrier 2 and performs optical tracking on the optical tracking carrier 2 .

[0120] The light source 1 is an LED light source 11, and / or a medical cold light source 12, and / or natural light. The light source 1 may be various light sources capable of emitting light rays, and the light rays emitted from the light source 1 can be traced after being transmitted through the optical tracking carrier 1. Referring to FIG. 11, the LED light source 11 has features such as a small volume, high luminous efficiency, and strong light source directivity compared to general illumination light sources, and in particular, in terms of safety, the LED light source has an advantage that cannot be compared with general light sources. First, the LED light source is a low-voltage DC power source, and the power supply voltage only needs to be 6 to 24 V; second, the LED light source does not contain mercury and does not cause damage such as poisoning to the human body; and more importantly, the LED light source is a cold light source, does not generate a large amount of heat during operation, is safe to touch, and does not cause unexpected high-temperature burns to the human body. Referring to FIG. 9, the medical cold light source 12 is a common light source used during conventional surgery, and the light source 1 can be placed later, is easy to obtain in the operating room, does not require additional equipment, and the medical cold light source 12 is not likely to cause an increase in body temperature.

[0121] The color of the light emitted from the light source 1 can be set according to the background color or transmission requirements.

[0122] By setting the light beam, in clinical operation, the doctor can directly see the location of the optical tracking carrier 2 through the tissue with the naked eye, and can also accurately identify the blood vessels, tissues or organs that need to be protected in clinical operation, effectively avoiding accidental damage during operation. The light beam emitted from the light source 1 can be set according to the background color or tissue that needs to be penetrated in the body cavity. When it is necessary to penetrate the tissue, red and yellow are preferred, followed by purple and white, and when it is necessary to display the blood vessel tissue, the light beam is preferably green.

[0123] The light source 1 can be set to be intermittently lit, flashing, etc. as required, and the intensity of the light emitted from the light source 1 can be adjusted as required to suit different clinical environments. The illuminance of the light emitted from the light source 1 can reach 300,000 lux, and the preferred range is 5,000 lux to 150,000 lux.

[0124] 9 and 13, the light source 1 includes a control system 13 including a wavelength adjusting mechanism 13-1 and a light intensity adjusting mechanism 13-2, the wavelength adjusting mechanism 13-1 can adjust the color of the emitted light by adjusting the wavelength, and the light intensity adjusting mechanism 13-2 can adjust the illuminance of the emitted light.

[0125] The LED light source 11 may be installed inside or outside the body. The volume of the light emitting end 11-1 of the LED light source 11 can be very small, and the size of the light emitting end 11-1 is usually controlled to be 2mm or less, for example, the package size is 0.2mm to 0.5mm for an LED lamp. Therefore, referring to Fig. 11 to Fig. 12-3, the LED light source 11 can not only be installed outside the body and transmit light into the human body through the optical tracking carrier 2, but also be installed directly inside the human body, cover the outside with the optical tracking carrier 2, and install directly on the part that needs tracking.

[0126] In this embodiment, the light source 1 can be connected to the optical tracking carrier 2 through the light-guiding connector 26 to provide a light source, and the LED light source 11 can be provided in the optical tracking carrier 2. The optical tracking carrier 2 is directly wrapped around the outside of the LED light source 11, and the LED light source 11 is set in the human body together with the optical tracking carrier 2 to track internal cavities, organs, tumors, etc.

[0127] 1 to 3-2, the optical tracking carrier 2 is a light-guiding optical fiber 22. The light-guiding optical fiber 22 has a good light-guiding effect, can transmit light to different positions as required, and can be connected or disconnected as required, which is very convenient for clinical use.

[0128] The optical tracking carrier 2 includes at least one of the light-guiding optical fibers 22 .

[0129] The end and / or side of the light-guiding optical fiber 22 can be illuminated. The light-guiding optical fiber 22 can be illuminated not only at its end but also at its side, and the light-guiding optical fiber 22 can be lit up as a whole to emit light.

[0130] The optical tracking carrier 2 is a combination of a plurality of the light-guiding optical fibers 22 .

[0131] The optical tracking carrier 2 may be composed of a single light-guiding optical fiber 22 (see Figures 1, 2 and 3), or, see Figure 15, may be a combination of multiple light-guiding optical fibers 22, and may be in various forms, such as forming an optical fiber bundle, weaving it into a mesh shape, arranging it at different lengths, etc.

[0132] The light-guiding optical fiber 22 has a smooth surface. When the light-guiding optical fiber 22 has a smooth surface, due to the good light-guiding performance of the light-guiding optical fiber 22, the light exit port 22-2 of the light-guiding optical fiber 22 is located at the distal end of the light-guiding optical fiber 22, and fixed-point tracking can be realized.

[0133] The light-guiding optical fiber 22 has a non-smooth surface 22-1.

[0134] The non-smooth surface 22-1 is a non-smooth surface 22-11 that can form reflection and / or scattering, and the non-smooth surface 22-1 can realize the overall illumination of the non-smooth surface 22-1 through the reflection and / or scattering of light, and achieve the effect of overall tracking.

[0135] The light-guiding optical fiber 22 is provided with light outlets 22-2 at intervals. Each of the light outlets 22-2 has a light conducting surface 22-21 and a reflecting surface 22-22, and the light is conducted through the conducting surface 22-21 and is reflected when it reaches the reflecting surface 22-22, and is output from the light outlet 22-2 to form a tracking point, and a plurality of the light outlets 22-2 can form a chain-like tracking band, see FIG.

[0136] The light outlet 22-2 is a non-axial light outlet 22-21, which is provided on a side of the light-guiding optical fiber 22 along the length direction of the light-guiding optical fiber 22. When the light outlet 22-2 is provided completely along the length direction of the light-guiding optical fiber 22, the entire light-guiding optical fiber 22 can be illuminated along the length direction of the light-guiding optical fiber 22, and the entire tracking of the light-guiding optical fiber 22 can be realized.

[0137] The non-axial light emission port 22-21 may be a point-like intermittent light emission port manufactured by mold pressing, as shown in Figures 1 to 1-4, or may be an annular light emission port or a spiral light emission port manufactured by integral injection molding or wire cutting, as shown in Figures 2 to 3-2.

[0138] Due to the regular arrangement of the light exit ports 22-2, the light exit ports 22-2 can mark the length size of the light-guiding optical fibers 22.

[0139] Due to the regular arrangement of the distribution density of the light exit ports 22-2, the intensity of the scattered light varies, and the length size of the light-guiding optical fiber 22 is marked.

[0140] Referring to FIG. 1, when the light outlets 22-2 are closely arranged, the emitted light is stronger and the visual effect is brighter; when the light outlets 22-2 are sparsely arranged, the emitted light is weaker and the visual effect is darker. By using such an arrangement method that combines light and dark, a visual effect similar to a ruler can be formed, and the effect of size marking can be achieved while being tracked.

[0141] Referring to FIG. 15, the light-guiding optical fiber 22 can also be woven in a mesh-like shape, with the light outlets 22-2 scattered at different positions. When the light-guiding optical fiber 22 is woven in a mesh-like shape, the length of each light-guiding optical fiber 22 is set to be distinct, and the light outlets 22-2 of the light-guiding optical fiber 22 are also distinguished and scattered accordingly, so that the overall tracking of the three-dimensional space can be realized, and since there is no need to provide the light outlets 22-1 in the middle of each light-guiding optical fiber 22, the light transmission effect is better, and the visual effect of a single tracking point is very bright. The light outlets 22-2 are provided on the side of the light-guiding optical fiber 22, which can be lit up as a whole, can also be woven in a mesh-like shape to realize the tracking of the entire area of ​​the entire cavity. In addition, the mesh-like shape can have good support, and is particularly suitable for supporting and tracking large cavities such as the bladder and uterus.

[0142] Referring to FIG. 10 and FIG. 10-1, the light source can also be connected to the optical tracking carrier 2 in a non-contact form, and irradiated to the optical tracking carrier 2 such as the light-storing spontaneous light tracking carrier 21, thereby realizing the tracking of the optical tracking carrier 2 through the storage and conversion of light energy. The optical tracking carrier 2 is the light-storing spontaneous light tracking carrier 21. The spontaneous light material refers to a material that can absorb energy in a specific way and convert it into non-equilibrium light radiation, and the process of converting the energy absorbed inside the material into non-equilibrium light radiation is the luminescence process. In particular, the light-storing spontaneous light material can continue to emit light for more than 12 hours in a dark environment after several minutes or tens of minutes under the action of external lighting, which can meet the tracking needs of most surgery times. The light-storing spontaneous light tracking carrier 21 can directly absorb the energy of the lamp in the operating room, so that various external lights can all be the light source 1, and there is no need to directly connect to the light source 1, and the use process is very simple.

[0143] Generally, the light-storing self-luminous tracking carrier 21 includes a light-storing self-luminous body 21-1 and a protective carrier 21-2. The protective carrier 21-2 is made of a transparent light-guiding material, and the light-storing self-luminous body 21-1 is encapsulated in the protective carrier 21-2.

[0144] The light-storage self-illuminating body 21-1 can absorb and convert external energy to emit light. The protective carrier 21-2 is made of transparent medical materials and can directly contact tissue, so that the light emitted by the energy conversion of the light-storage self-illuminating body 21-1 can be effectively transmitted and effectively tracked, and biological safety is also guaranteed in clinical use. The light-storage self-illuminating body 21-1 can be installed at different positions and designed in different shapes to perform fixed-point tracking or overall tracking as needed.

[0145] 8 and 8-1, the medical optical tracking system 500 further includes a coating 3 on its surface.

[0146] Said coating 3 is an anticoagulant coating, and / or a hydrophilic coating, and / or a hydrophobic coating.

[0147] The coating 3 can be designed to have different properties as needed, for example, when the optical tracking carrier 2 needs to enter blood vessels, the coating 3 can be designed as an anticoagulant coating, and when the optical tracking carrier 2 needs to enter various cavities, the coating 3 can be designed as a hydrophilic coating or a hydrophobic coating as needed.

[0148] 1 and 15, the optical tracking carrier 2 includes a delivery unit 23. The delivery unit 23 can deliver the working unit 2-1 of the optical fiber tracking carrier 2 to a part that needs tracking, such as a blood vessel, a cavity, a tumor operation site, etc. as needed. The delivery unit 23 includes a delivery handle 23-1.

[0149] 37 and 37-1, the delivery portion 23 is movably mounted on the optical tracking carrier 2. In clinical applications, the delivery portion 23 can be detached from the optical tracking carrier 2 or moved relative to the optical tracking carrier 2 as required.

[0150] The medical optical tracking system 500 further includes a developing mechanism 4 .

[0151] The developing mechanism 4 is made of metal and has a thermal conduction function, which can prevent the medical optical tracking system 500 from being accidentally damaged due to the temperature of the part of the medical optical tracking system 500 that is inserted into the human body being too high, and the temperature is normally controlled to be below 37°C.

[0152] 4 to 6-1, the developing mechanism 4 is a developing line 41, and / or a developing ring 42, and / or a developing block 43. The applicant only gives examples of some of the above-mentioned developing methods, but in practical applications, those skilled in the art can design different developing methods as needed, and the applicant does not give examples of them one by one here, but all of them are within the scope of protection of the present application.

[0153] The developing mechanism 4 can develop with X-ray, and / or MRI, and / or B ultrasound. The developing mechanism 4 can develop and present scenes such as X-ray, magnetic navigation, or B ultrasound, making it easy to set the optical tracking carrier 2 in an observation or navigational situation, and is particularly suitable for setting on important blood vessels, solid tumors, etc.

[0155] The protective sleeve 5 is made of a transparent material, and the optical tracking carrier 2 is placed in the protective sleeve 5. The protective sleeve 5 is made of a medical transparent material, which can protect the optical tracking carrier 2, and the transparent material can still ensure the tracking effect of the optical tracking carrier 2.

[0156] 1-4, the optical tracking carrier 2 includes a channel 24 therein. The channel 24 can be used as a surgical instrument channel, a bodily fluid drainage channel, or the like, as desired.

[0157] The optical tracking carrier 2 is made of flexible medical materials and can move along the cavities such as blood vessels, ureters, esophagus, trachea, fallopian tubes, spermatic ducts, etc. The optical tracking carrier 2 has good flexibility and can move along the blood vessels or cavities, so that it can be set in different positions according to needs.

[0158] 7, the optical tracking carrier 2 includes a shaping mechanism 25. The shaping mechanism 25 can shape the optical tracking carrier 2, for example, into various shapes such as circular, arc, spherical, etc. as required to meet different tracking needs.

[0159] The shaping mechanism 25 is a shape-memory shaping mechanism 25-1. The shape-memory shaping mechanism 25-1 has a simple structure such as a line or stripe at room temperature for easy setting, and returns to the set shape under the action of body temperature after entering the human body.

[0160] The shape memory shaping mechanism 25-1 is made of a shape memory metal wire woven and / or carved from a shape memory metal tube or sheet. The shape memory shaping mechanism 25-1 may be woven into a desired shape with a shape memory metal wire, or may be directly carved into a desired shape using a shape memory alloy tube or a shape memory alloy sheet.

[0161] In clinical applications, the optical tracking carrier 2 of the medical optical tracking system of this embodiment may be set in each location that requires tracking as needed, such as each internal cavity of the ureter, vas deferens, fallopian tube, etc., or may be set in solid tumors such as uterine fibroids, lung tumors (especially lung nodules), liver tumors, etc., and may even be set in blood vessels, and in particular, by utilizing the feature that the light-guiding optical fiber 2 can emit light from the side to realize overall tracking, each internal cavity, blood vessel, solid tumor, etc. can be marked.

[0162] The medical optical tracking system of this embodiment can transmit the light beam emitted from the light source 1 through the optical tracking carrier 2, and then perform optical tracking on the optical tracking carrier 2. By setting different color light sources, the optical tracking carrier 2 can accurately mark the blood vessels, cavities, tissues or organs that should be protected in clinical operation, effectively avoiding accidental damage during operation, or effectively defining small tumors, and facilitating the effective implementation of clinical operation.

[0165] 14 and 14-1, the blood vessel tracking device 920 includes a delivery end 920-1, a guidewire 920-2, a protective sleeve 5 and the medical optical tracking system 500.

[0166] In this embodiment, the light source 1 of the medical optical tracking system 500 adopts a medical cold light source 12, which can better prevent the temperature of the optical tracking carrier 2 installed in the body from rising, and make the vascular tracking process safer.

[0167] The light source 1 includes a control system 13 including a wavelength adjustment mechanism 13-1 and a light intensity adjustment mechanism 13-2, where the wavelength adjustment mechanism 13-1 can adjust the color of the emitted light by adjusting the wavelength, and the light intensity adjustment mechanism 13-2 can adjust the illuminance of the emitted light.

[0168] The color of the light emitted from the light source 1 can be set according to the background color or the penetration requirements. Through the light setting, in clinical operation, the doctor can directly see the location of the optical tracking carrier 2 through the tissue with the naked eye, and can also accurately identify the blood vessels that need to be protected in clinical operation, so as to effectively avoid accidental damage during operation. The light emitted from the light source 1 can be set according to the background color or the tissue that needs to be penetrated in the body cavity. When it is necessary to penetrate the tissue, red and yellow are preferred, followed by purple and white, and when it is necessary to display the vascular tissue, the light is preferably green.

[0169] The light source 1 can be set to be intermittently lit, flashing, etc. as required, and the intensity of the light emitted from the light source 1 can be adjusted as required to suit different clinical environments.

The guide wire 920-2 can shape the distal end of the blood vessel tracking device 920 as needed, adapt to the radian of the blood vessel, and make the delivery process easier. During the shaping of the guide wire 920-2, the light-guiding optical fiber 22 is also deformed accordingly, ensuring the tracking effect of the blood vessel tracking device 920.

The light source 1 of the medical optical tracking system 500 is an LED light source 11, and the light-emitting end 11-1 of the LED light source 11 is installed in the tube wall of the catheter 900-1 to track the catheter 900-1. The LED light source 11 includes a light-emitting end 11-1 with a small volume, whereby the light-emitting end 11-1 is directly installed in the tube wall of the catheter 900-1 and connected to a power source through a circuit system 11-2, and can emit light in the tube wall of the catheter 900-1.

[0196] The light emitting end 11-1 can also be provided at any position on the catheter 900-1 as needed to achieve local or global tracking of the catheter 900-1.

[0197] 17-8 and 17-9, when the light emitting end 11-1 of the LED light source 11 is provided at the distal end 900-11 of the catheter 900-1, local fixed point tracking can be performed on the distal end 900-11 of the catheter 900-1.

[0198] Referring to Figures 17-11 and 17-12, when the circuit system 11-2 adopts a flexible circuit board 11-21, the light emitting end 11-1 can be distributed at any position on the flexible circuit board 11-21, and if the flexible circuit board 11-21 is installed inside the tube wall of the catheter 1, an LED lamp strip or LED lamp network can be formed, and global tracking can be performed for the catheter 900-1.

[0199] Referring to Figures 17-1 to 17-7, when the LED light source 11 is installed outside the body, the optical tracking carrier 2 of the medical optical tracking system 500 is a light-guiding optical fiber 22, and a light-guiding connector 26 is connected to the proximal end of the light-guiding optical fiber 22, and the light-guiding optical fiber 22 is installed along the longitudinal direction of the catheter 900-1 to track the catheter 900-1.

[0200] 17-1 and 17-2, when the light-guiding optical fiber 22 has a smooth surface, the light outlet 22-2 is provided at the distal end of the catheter 1, ie, tracks the distal end 900-11 of the catheter 900-1.

[0201] 17-5 to 17-7, when the light-guiding optical fiber 22 has a non-smooth surface 22-1, the light exit port 22-2 provided on the side emits scattered light, and global tracking of the catheter 900-1 can be performed.

[0202] 20 to 21-1, the light-guiding optical fiber 22 can further be woven in a mesh-like shape to provide overall tracking of the catheter 900-1, and by being woven in a mesh-like shape, the light-guiding optical fiber 22 can also utilize its elastic supporting force to support the tubular wall of the catheter 900-1.

[0203] Referring to FIG. 17-13, the outer surface of the catheter 900-1 may further be provided with a coating 3, such as a hydrophilic coating, if desired.

The applicant only lists some of the above-mentioned application scenarios of the medical catheter 900 with a tracking device here, but in actual application, the medical catheter 900 with a tracking device can be designed as required structures for different application scenarios according to clinical needs.

[0205] Referring to FIG. 22, the medical catheter 900 may further be provided with a shaping mechanism 25 for shaping the catheter 900-1 to accommodate different lumens.

[0206] 17 to 17-15, the medical catheter 900 with a tracking device is a medical stomach tube 901.

[0207] The medical gastric tube 901 includes a catheter 900-1, an interface 900-2 and a medical optical tracking system 500, in which a working opening 900-11-1 is provided at a distal end 900-11 of the catheter 900-1, and the medical optical tracking system 500 tracks the catheter 900-1.

[0208] The medical gastric tube 901 enters the stomach through the esophagus and is an artificial delivery channel for food, and the interface 900-2 can be externally connected to a food injection device. In clinical surgery, it may be necessary to grasp and observe the position of the distal end 900-11 of the catheter 900-1, in which case the medical optical tracking system 500 only needs to perform local tracking of the distal end of the medical gastric tube 901. In other cases, such as when performing surgery along the esophagus, it is necessary to perform global tracking of the medical gastric tube 901 to prevent accidental damage to the esophagus.

[0209] 17-8 and 17-9, when it is necessary to perform local tracking of the distal end of the medical gastric tube 901, a technical solution may be adopted in which the light-emitting end 11-1 of the LED light source 11 is individually or collectively arranged at the distal end of the catheter 900-1 for tracking, or the light-guiding optical fiber 22 having a smooth surface may be adopted, which may be a single light-guiding optical fiber 22 or a light-guiding bundle consisting of a plurality of light-guiding optical fibers 22, and the distal end of the catheter 900-1 is tracked using the light emission port 22-1 at the end, or the light-guiding optical fibers 22 are arranged circumferentially along the side wall of the catheter 900-1 to form a halo at the distal end of the catheter 900-1, and local tracking of the distal end of the catheter 900-1 may be performed.

[0210] 17-11 and 17-12, when it is necessary to perform whole or large-area tracking of the medical gastric tube 901, the light-emitting ends 11-1 of the LED light sources 11 may be distributed in the wall of the catheter 900-1 to form a light-guiding strip or a light-guiding network to perform whole or large-area tracking of the catheter 900-1. The light-guiding optical fiber 22 with a non-smooth surface 22-1 may be provided in the wall of the catheter 900-1 along the length to form a light-guiding strip to track the catheter 900-1 in the length direction, or the light-guiding optical fiber 22 may be woven in a mesh shape to perform circular whole tracking of a specific segment or the entire catheter 900-1.

[0211] The medical catheter with tracking device 900 is a medical urinary catheter 902 .

[0212] The medical urinary catheter 902 includes a catheter 900-1, an interface 900-2 and a medical optical tracking system 500, in which a working opening 900-11-1 is provided at a distal end 900-11 of the catheter 900-1, and the medical optical tracking system 500 tracks the catheter 900-1.

[0213] The medical optical tracking system 500 can perform fixed point tracking on the medical urinary catheter 902 and can also perform large range or overall tracking on the medical urinary catheter 902 .

[0214] For example, when it is necessary to perform fixed-point or small-range local tracking of the working end of the medical urethral catheter 902, a technical solution may be adopted in which the light-emitting end 11-1 of the LED light source 11 is individually or collectively arranged at the distal end of the catheter 900-1 for tracking; the light-guiding optical fiber 22 having a smooth surface may be adopted, and may be a single light-guiding optical fiber 22 or a light-guiding bundle consisting of a plurality of light-guiding optical fibers 22, and the light emission port 22-1 at the end may be used to track the distal end of the catheter 900-1; or the light-guiding optical fibers 22 may be arranged circumferentially along the side wall of the catheter 900-1 to form a halo at the distal end of the catheter 900-1, and local tracking of the distal end of the catheter 900-1 may be performed.

[0215] For example, when it is necessary to perform local tracking of the bladder or global tracking of the catheter 900-1, the light emitting ends 11-1 of the LED light sources 11 may be distributed in the wall of the catheter 900-1 to form a light guide strip or a light guide network to perform global or large-area tracking of the catheter 900-1. A light guide optical fiber 22 having a non-smooth surface 22-1 may be provided along the length of the wall of the catheter 900-1 to form a light guide strip to track the catheter 900-1 in the length direction, or the light guide optical fiber 22 may be woven in a mesh pattern to perform global tracking of the outer circumference of the balloon 900-13.

[0216] 18 to 18-7, the medical urethral catheter 902 is a double lumen urethral catheter 902-1.

[0217] A balloon 900-13 is provided at the distal end 900-11 of the catheter 900-1 of the double-lumen urethral catheter 902-1, two lumens 1-1 are provided in the catheter 900-1, and one interface 900-2 is provided corresponding to each of the lumens 1-1, of which one lumen 1-1 constitutes a urinary catheterization lumen 900-14, the working opening 900-11-1 is provided at the distal end of the urinary catheterization lumen 900-14, the interface 900-2 provided at the proximal end constitutes a drainage port 900-21, the other lumen 1-1 constitutes a water injection lumen 900-15, the distal end of the water injection lumen 900-15 is connected to the balloon 900-13, and the interface 900-2 connected to the proximal end constitutes a water injection port 900-22.

[0218] In order to meet the time requirements of clinical surgery, the medical urethral catheter 902 used during surgery generally needs to be provided with the balloon 900-13, and water can be injected into the balloon 900-13 from the water inlet 900-22 through the water inlet lumen 15 to form a water bag, which can ensure the effective fixation of the medical urethral catheter 902 in the bladder and prevent it from falling off.

[0219] 19 to 21-1, the medical urethral catheter 902 is a triple lumen urethral catheter 902-2.

[0220] The triple lumen urethral catheter 902-2 has a balloon 900-13 at the distal end 900-11 of the catheter 900-1, three lumens 1-1 are provided in the catheter 900-1, and one interface 900-2 is provided corresponding to each of the lumens 1-1, of which the first lumen 1-1 constitutes a urinary catheter lumen 900-14, the working opening 900-11-1 is provided at the distal end of the urinary catheter lumen 900-14, the interface 900-2 provided at the proximal end constitutes a drainage port 900-21, and the second The lumen 1-1 constitutes a water injection lumen 900-15, the distal end of which is connected to the balloon 900-13, and the interface 900-2 connected to the proximal end constitutes a water injection port 900-22, the third lumen 1-1 constitutes an infusion flushing lumen 900-16, the distal end of which is provided with a water flushing port 900-16-1 and a shutoff valve 900-16-2, and the interface 900-2 connected to the proximal end of the infusion flushing lumen 900-16 constitutes a water flushing drug inlet 900-23.

[0221] In order to facilitate flushing, particularly flushing and disinfection with medicine, of the medical urinary catheter 902 during its placement, the medical urinary catheter 902 may be the triple lumen urinary catheter 902-2. The flushing medicine inlet 900-23 is provided at the proximal end of the infusion flushing lumen 900-16, and the flushing port 900-16-1 at the distal end communicates with the body cavity, and the shutoff valve 900-16-2 is provided at the flushing port 900-16-1. When medicine is injected from the flushing medicine inlet 900-23, the shutoff valve 900-16-2 opens under the action of pressure, allowing the medicine to enter the body cavity; when the injection of the medicine is stopped, the shutoff valve 900-16-2 automatically closes under the action of the pressure of the body cavity, preventing body fluids from entering the infusion flushing lumen 900-16 from the flushing port 900-16-1.

[0222] 23, in clinical use, a medical professional inserts the medical urethral catheter 902 into the bladder, injects saline into the balloon 900-13 from the water inlet 900-22, the balloon 900-13 expands, and the medical urethral catheter 902 is fixed in the bladder. The light source 1 is turned on, and the medical optical tracking system 500 tracks the catheter 900-1. When the medical urethral catheter 902 needs to be inserted into the ureter, the catheter 900-1 is provided with a development line 41, and the medical urethral catheter 902 is delivered to the position where tracking is required by X-ray, and then the light source 1 is turned on, and under the action of the medical optical tracking system 500, the ureter is marked with visible light, see FIG. 24.

[0223] The medical catheter with a tracking device of this embodiment includes the medical optical tracking system 500, so that after entering the human body, it can be tracked by visible light. In clinical surgery, when approaching the tracked lumen, the light emitted from the light source 1 can be seen penetrating the lumen through the tissue. The illuminance of the light emitted from the light source 1 ensures that the tracked lumen can be clearly seen when the distance from the tube wall is about 0-30 mm. The closer to the lumen, the stronger the light is, and the clearer the presentation effect is. This can effectively perform vascular tracking during surgery and present it to medical personnel, protect important lumen, and prevent unexpected damage during surgery. It is very easy and safe for clinical use.

[0224] Example 4: Solid tumor tracking device of the present invention

[0225] Referring to FIG. 25, this embodiment discloses a technique and apparatus for visually defining solid tumors, and the solid tumor tracking apparatus of this embodiment includes the medical optical tracking system described in Example 1.

[0226] Referring to Figures 25 to 29-1, the solid tumor tracking device 910 includes a positional deviation prevention mechanism 910-1, a delivery mechanism 910-2, a development mechanism 4 and the medical optical tracking system 500, and the optical tracking carrier 2 of the medical optical tracking system 500 is provided in the positional deviation prevention mechanism 910-1 and tracks the positional deviation prevention mechanism 910-1.

[0227] In this embodiment, the misalignment prevention mechanism 910-1 is made of metal material and forms the developing mechanism 4; see Figures 25-1 and 26, in practical applications, the developing mechanism 4 can be further provided separately to enhance the developing effect.

[0228] The anti-slip mechanism 910-1 can be fixed to the solid tumor that needs to be defined to prevent the solid tumor tracking device 910 from shifting due to human body movements such as respiratory movement of the lungs, peristalsis of the intestines, and peristalsis of the stomach.

[0229] The displacement prevention mechanism 910-1 has a hook-shaped structure (see FIG. 26), and / or a spherical structure (see FIG. 30), and / or a horn-shaped structure (see FIG. 31 to FIG. 31-4), and / or a coil spring-shaped structure (see FIG. 32 and FIG. 32-1), and / or a nail-shaped structure. The applicant has only illustrated the above-mentioned several structures of the displacement prevention mechanism 910-1, but in practical applications, those skilled in the art can design the displacement prevention mechanism 910-1 with different structures or a combination of multiple structures, such as a combination of a dumbbell shape and a coil spring shape (see FIG. 33 and FIG. 33-1), as needed, and the applicant will not illustrate each one here, but all of them are within the scope of protection of the present application. Referring to FIG. 31-4, the outer surface of the displacement prevention mechanism 910-1 can also be provided with the coating 3 as needed.

[0230] 26, the anti-slip mechanism 910-1 has a hook-like structure, and includes at least one positioning hook 910-11. Usually, the anti-slip mechanism 910-1 includes two or three positioning hooks 910-11 to better prevent the anti-slip mechanism 910-1 from being displaced due to human body movements such as lung breathing, intestinal peristalsis, etc.

[0231] Referring to Figures 25-1 to 29, in this embodiment, the optical tracking carrier 2 is a light-guiding optical fiber 22, a light-guiding connector 26 is connected to the proximal end of the light-guiding optical fiber 22, the distal end of the light-guiding optical fiber 22 is connected or fixed to the positional deviation prevention mechanism 910-1, and the light emission port 22-2 of the light-guiding optical fiber 22 is provided in the positional deviation prevention mechanism 910-1 and tracks the positional deviation prevention mechanism 910-1.

[0232] 26-1 to 26-3, the light-guiding optical fiber 22 has a non-smooth surface 22-1, a light outlet 22-2 is provided on a side surface of the light-guiding optical fiber 22, and the light-guiding optical fiber 22 performs overall tracking with respect to the displacement prevention mechanism 910-1. Since the light-guiding optical fiber 22 can be turned on as a whole, if the light-guiding optical fiber 22 is wound around the displacement prevention mechanism 910-1, particularly the positioning hook 910-11, it can perform overall tracking with respect to the displacement prevention mechanism 910-1.

[0233] 26, the light-guiding optical fiber 22 is made of a flexible medical material and is connected and fixed to the displacement prevention mechanism 910-1, and when the displacement prevention mechanism 910-1 is deformed, the light-guiding optical fiber 22 is deformed along with the displacement prevention mechanism 910-1. Since the light-guiding optical fiber 22 can be turned on as a whole, if the light-guiding optical fiber 22 is wound around the displacement prevention mechanism 910-1, particularly the positioning hook 910-11, it can be deformed along with the displacement prevention mechanism 910-1. In particular, if the displacement prevention mechanism 910-1 is made of a shape memory alloy, the shape of the light-guiding optical fiber 22 will also change as the shape of the displacement prevention mechanism 910-1 changes, ensuring the tracking effect of the displacement prevention mechanism 910-1.

[0234] Referring to FIG. 25, the delivery mechanism 910-2 includes a delivery sheath 910-21 and an extrusion mechanism 910-22; referring to FIG. 26, the anti-shift mechanism 910-1 is provided within the delivery sheath 910-21, and the extrusion mechanism 910-22 can extrude the anti-shift mechanism 910-1 from the delivery sheath 910-21.

[0235] 37 and 37-1, the extrusion mechanism 910-22 may be fixedly connected to the displacement prevention mechanism 910-1 and remain in the body together with the displacement prevention mechanism 910-1 after the displacement prevention mechanism 910-1 is pushed out of the delivery sheath 910-21, or may be detachably connected to the displacement prevention mechanism 910-1 and, after the displacement prevention mechanism 910-1 is pushed out of the delivery sheath 910-21, the connection with the displacement prevention mechanism 910-1 is released and only the displacement prevention mechanism 910-1 is left in the solid tumor.

[0236] Referring to Figures 27 and 27-1, when the light source 1 of the medical optical tracking system 500 adopts a mini-sized LED light source 11, generally, the light-emitting end 11-1 is an LED lamp whose size is controlled to be 2 mm or less, for example, whose package size is between 0.2 mm and 0.5 mm, and the light-emitting end 11-1 can be installed inside the body.

[0237] The optical tracking carrier 2 is made of a transparent material, and the light emitting end 11-1 of the LED light source 11 is packaged in the optical tracking carrier 2 and is provided in the positional deviation prevention mechanism 910-1 together with the optical tracking carrier 2, so that the positional deviation prevention mechanism 910-1 can be tracked.

[0238] The light emitted from the light emitting end 11-1 is transmitted through the light-guiding material of the optical tracking carrier 2 and then displayed, which can be used to clinically identify the location of solid tumors.

[0239] The LED light source 11 includes a light emitting end 11-1, a circuit system 11-2, a driving plate 11-3 and a power source 11-4, the light emitting end 11-1 is connected to the driving plate 11-3 and the power source 11-4 via the circuit system 11-2, and under the control of the driving plate 11-3, the power source 11-4 supplies power to the light emitting end 11-1 via the circuit system 11-2, the light emitting end 11-1 emits light, the driving plate 11-3 and the power source 11-4 are arranged outside the body, and the light emitting end 11-1 is arranged inside the body, and tracks the positional deviation prevention mechanism 910-1.

[0240] The circuit system 11-2 is a flexible circuit board 11-21, and the light emitting end 11-1 of the LED light source 11 is distributed on the flexible circuit board 11-21 and packaged in the optical tracking carrier 2 to form an LED lamp strip, an LED lamp network, or an LED lamp ball, which is mounted on the anti-shift mechanism 910-1 and tracks the anti-shift mechanism 910-1.

[0241] The LED light source 11 may be one that performs fixed point tracking after packaging the single light emitting end 11-1.

[0242] When the circuit system 11-2 adopts a flexible circuit board 11-21, the light emitting end 11-1 of the LED light source 11 is distributed on the flexible circuit board 11-21 and packaged together in the optical tracking carrier 2 to form an LED lamp strip, an LED lamp network, or an LED lamp ball, which is mounted on the anti-shift mechanism 910-1 and performs overall tracking with respect to the anti-shift mechanism 910-1.

[0243] The light emitting end 11-1 of the LED light source 11 can further be directly mounted on the anti-shift mechanism 910-1, the exterior of which is covered by the optical tracking carrier 2 made of a transparent material, and the light beam emitted from the light emitting end 11-1 tracks the anti-shift mechanism 910-1.

[0244] The light emitting ends 11-1 are distributed in the anti-shift mechanism 910-1, and the exterior is covered by the optical tracking carrier 2 made of a transparent material, thus the light emitting ends 11-1 are perfectly attached to the exterior contour of the anti-shift mechanism 910-1, and can be tracked for any shape of the anti-shift mechanism 910-1.

[0245] Also, referring to Figures 31 to 31-4, the light-emitting end 11-1 is arranged symmetrically and its exterior is covered by the optical tracking carrier 2, and the position shift prevention mechanism 910-1 can be constructed by utilizing the internal support of the light-emitting end 11-1 and the circuit system 11-2 and the volume of the light-emitting end 11-1 itself, and the medical optical tracking system 500 can simultaneously perform the tracking function and the positioning function of the position shift prevention mechanism 910-1.

[0246] The circuit system 11-2 is a flexible circuit board 11-21, the optical tracking carrier 2 is made of a flexible transparent material, the light emitting end 11-1, the flexible circuit board 11-21 and the developing mechanism 4 are arranged together in the optical tracking carrier 2, and are arranged in the displacement prevention mechanism 910-1, when the displacement prevention mechanism 910-1 is deformed, the light emitting end 11-1, the flexible circuit board 11-21 and the developing mechanism 4 are deformed together with the optical tracking carrier 2 and the displacement prevention mechanism 910-1. In particular, when the displacement prevention mechanism 910-1 is made of a shape memory alloy, with the shape of the displacement prevention mechanism 910-1 changing, the shape of the flexible circuit board 11-21 also changes, ensuring the tracking effect of the displacement prevention mechanism 910-1.

[0247] Referring to FIG. 37, in clinical applications, when it is necessary to define a lung tumor (especially a lung nodule) or a liver tumor, the displacement prevention mechanism 910-1 is provided in the delivery sheath 910-21, and under X-ray conditions, the delivery sheath 910-21 is inserted into the location of the solid tumor, and then the extrusion mechanism 910-22 is used to extrude the displacement prevention mechanism 910-1 and fix it to the solid tumor, such as a lung tumor (especially a lung nodule) or a liver tumor, and then the delivery sheath 910-21 is removed, and the displacement prevention mechanism 910-1 is left and fixed to the solid tumor, and the light-guiding optical fiber 22 is connected to the light source 1, referring to FIG. 37-1, during surgery, the light source 1 is turned on, and the optical tracking carrier 2 tracks the displacement prevention mechanism 910-1, and then, under the guidance of the light, the location of the solid tumor, such as a lung tumor (especially a lung nodule) or a liver tumor, can be intuitively observed with the naked eye.

[0248] In clinical applications, for example, when uterine fibroids need to be defined, the anti-misplacement mechanism 910-1 can be delivered to and fixed on the uterine fibroids under the guidance of B ultrasound; during surgery, the light source 1 is turned on, and the optical tracking carrier 2 tracks the anti-misplacement mechanism 910-1; then, under the guidance of the light, the location of the uterine fibroids can be intuitively observed with the naked eye.

During surgery, the light source 1 is turned on, and the optical tracking carrier 2 tracks the anti-displacement mechanism 910-1. Then, under the guidance of the light, the location of the solid tumor can be intuitively observed with the naked eye, making clinical surgery safer and easier.

Although the preferred embodiments of the present invention have been introduced and described in this specification, it is obvious to those skilled in the art that these embodiments are merely illustrative examples, and those skilled in the art can make multiple changes, improvements and substitutions without departing from the present invention, so the protection scope of the present invention should be limited according to the spirit and scope of the appended claims.
