Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a laparoscopic surgery limit positioning device. Background Art

[0002] With the continuous advancement of medical technology, surgical techniques are moving towards minimally invasive and precise surgery, which not only improves the quality of life of patients, but also significantly reduces the risk of postoperative complications. Among the many types of surgeries, precise surgical positioning is a key factor in ensuring the success of the surgery and improving the postoperative effect. Especially in the field of laparoscopic surgery of the breast and thyroid, since these areas do not have natural cavities like the abdominal and thoracic cavities and lack clear tissue structure markers, it is often necessary to artificially create surgical space.

[0003] In this case, it becomes particularly critical to adopt a specific method of surgical boundary marking. For example, in laparoscopic mastectomy and prosthesis implantation, it is crucial to accurately locate the inframammary fold and annular ligament. If the positioning of the inferior fold is inaccurate, the prosthesis will be placed too high or too low, which will cause asymmetry of the patient's breasts and affect the appearance. Moreover, the application of surgical positioning technology is not limited to breast cancer surgery. In laparoscopic-assisted breast-conserving surgery, accurate positioning of tumor masses, and other types of surgery such as robot-assisted thyroid cancer resection, accurate positioning also plays a vital role. The precise application of these technologies provides a strong guarantee for the success rate of the operation and the patient's postoperative recovery.

[0004] In the above operations, surgeons usually need to apply pressure on the skin (such as pressing the location to be located with fingers) to facilitate observation in the laparoscope lens to assist in identification. However, the marks formed under the laparoscope by this method are often large in range and the positioning is not precise enough. Summary of the invention

[0005] The purpose of the present invention is to provide a laparoscopic surgery limit positioning device, which can provide a more accurate positioning mark for the laparoscope, thereby facilitating the laparoscopic surgery limit positioning.

[0006] The present invention adopts the following technical scheme: a laparoscopic surgery limit positioning device, comprising a flexible strip-shaped belt body, and a positioning light assembly is arranged along the length direction of the strip-shaped belt body and on the same side;

[0007] The positioning lamp assembly includes a plurality of lamp bodies, each of which includes a light source and a lens;

[0008] A lamp body fixing belt is provided on the strip body and on both sides of the positioning lamp assembly, and the direction of the lamp body fixing belt is consistent with that of the positioning lamp assembly;

[0009] The lamp body fixing belt is used to press the front end of the positioning lamp assembly to a predetermined position during laparoscopic surgery.

[0010] Further, the lamp body includes a light source, a front lamp cover and a rear lamp cover;

[0011] The front light cover is used to press at the predetermined position during laparoscopic surgery.

[0012] Furthermore, a plurality of through holes are provided on the strip body;

[0013] Each rear lamp cover passes through the through hole, and a heat dissipation hole is provided on a portion of the rear lamp cover located outside the through hole.

[0014] Furthermore, an adhesive layer is provided on the surface of the lamp body fixing belt facing the predetermined position.

[0015] Furthermore, the cross section of the strip-shaped belt body is arc-shaped, the inner space of the arc is the lamp body installation space, and the front end of the lamp body protrudes from the installation space.

[0016] Furthermore, a plurality of lamp bodies are connected to a control device via a same connecting line, and the control device is used to adjust the brightness of the light source.

[0017] Furthermore, the control device is provided with an indication mark, a regulator and a variable resistor.

[0018] Furthermore, the same isolation paper is pasted on the adhesive layers of the two lamp body fixing straps, and the isolation paper also covers the installation space.

[0019] Furthermore, the inner surface of the strip body has a light shielding layer.

[0020] The beneficial effect of the present invention is that the present invention fixes a strip body with a positioning lamp assembly at a predetermined position in laparoscopic surgery, and then emits light through the lamp body, thereby forming a "light source line" at the predetermined position to facilitate observation in the laparoscope and achieve precise positioning of the laparoscopic surgery.

[0030] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] During laparoscopic or robotic breast or thyroid surgery, unlike the abdominal and thoracic structures, there is no natural cavity and no obvious anatomical structure. During laparoscopic mastectomy and breast reconstruction, the glandular tissue and fat tissue are often blurred in the laparoscopic lens, making it difficult to directly identify key structures such as the submammary fold and annular ligament under the laparoscopic lens. Inaccurate positioning of breast structures such as the submammary fold will cause the two breasts to be unable to be on the same horizontal plane, resulting in asymmetry and affecting beauty.

[0032] During laparoscopic breast-conserving surgery, accurate positioning of the tumor is crucial to the success of the operation, and finding the location of the tumor under laparoscopy is even more challenging, especially when the tumor is small or has decreased in size or even disappeared after neoadjuvant chemotherapy, accurate positioning becomes more difficult.

[0033] During robot-assisted thyroid cancer resection surgery, such as surgery performed via the areola approach, a larger cavity needs to be constructed. Due to the reduced visibility of tissue structures under laparoscopy, the cavity may be too large or too small, which will adversely affect the safety of the surgery.

[0034] In addition, although subgalvanic blue has been used for surgical positioning, its operation process is cumbersome and may increase the risk of flap necrosis, which limits its widespread clinical application.

[0035] The present invention discloses a laparoscopic surgery limit positioning device, such as Figure 1As shown, it includes a flexible strip body 10, and a positioning lamp assembly is arranged along the length direction of the strip body 10 and on the same side; the positioning lamp assembly includes a plurality of lamp bodies 20, and each lamp body 20 includes a light source 21 and a lens; a lamp body fixing belt 12 is provided on the strip body 10 and on both sides of the positioning lamp assembly, and the direction of the lamp body fixing belt 12 is consistent with that of the positioning lamp assembly; wherein, the lamp body fixing belt 11 is used to press the front end of the positioning lamp assembly to a predetermined position during laparoscopic surgery.

[0036] The present invention fixes a strip body 10 with a positioning lamp assembly at a predetermined position in laparoscopic surgery, and then emits light through a lamp body 20, thereby forming a "light source line" at the predetermined position for easy observation in the laparoscope, thereby achieving precise positioning of the laparoscopic surgery.

[0037] The strip body 10 can be made of fiber material to ensure its flexibility, so that it can be changed in shape according to the predetermined position of laparoscopic surgery and is suitable for different usage scenarios. Preferably, a plurality of lamp bodies 20 are arranged at intervals, so as to improve the heat dissipation efficiency and prevent the headlamp cover 22 from burning the skin due to excessive temperature. The lamp body fixing belt 12 is preferably also made of flexible material, and at the same time, a plurality of notches can be spaced apart on the side of the lamp body fixing belt 12. This can facilitate the bending of the lamp body fixing belt 12 and adapt to shape changes.

[0038] The lens is used in combination with the micro LED lamp to focus the light emitted by the LED lamp, so that a single lamp appears in the shape of a small dot under the laparoscope field of view, and multiple lamps are connected into a curved line to display the required surgical boundary, thereby improving the accuracy of positioning the surgical boundary;

[0039] The lens can be made of polymethyl methacrylate, which has good light transmittance and can gather light, thereby reducing light scattering and improving positioning accuracy. The material polymethyl methacrylate used for the lens has certain heat insulation properties, which can prevent the LED light from overheating and burning the skin.

[0040] In one embodiment, the front lamp cover 22 and the lens can be integrated into one, and the lens of the front lamp cover 22 slightly protrudes from the strip body 10. The tight fit of the tape ensures that the front lamp cover 22 fits tightly against the skin, which can not only show the surgical boundary indentation under the laparoscope, but also effectively reduce the artifacts caused by light scattering.

[0041] In addition, the lamp body fixing belt 11 can be a part of the strip body 10, and the length is the same as the strip body 10, so as to ensure that each headlamp cover 22 is pressed on the skin to form a complete "light source line" on the skin.

[0042] As a way to achieve this, Figure 2As shown, the lamp body 20 includes a light source 21, a front lamp cover 22 and a rear lamp cover 23; the front lamp cover 22 is used to press at a predetermined position during laparoscopic surgery. In fact, it is only necessary to ensure that a part of the front lamp cover 22 (such as the front end) is pressed at the predetermined position, and the contact area is reduced as much as possible, so that the indentation is more obvious and corresponds to the "light source line".

[0043] Exemplarily, the light source 21 can adopt a micro LED lamp, a heat sink and a photoelectric power source. The micro LED lamp has the advantage of adjustable light intensity, so that the light intensity of the micro LED can be adjusted according to different patients (different patients in the same type of laparoscopic surgery will have different tissue sizes and thicknesses), so as to minimize artifacts and achieve the possibility of precise positioning. At the same time, the micro LED lamp has the advantage of high brightness, which can achieve light projection through the skin, thereby achieving the possibility of visualization of the surgical area under laparoscope. The micro LED lamp has the advantage of low energy consumption, converting electrical energy into light energy, reducing the formation of heat energy, helping to reduce the demand for heat dissipation, and dissipating heat faster, which can avoid excessive heat energy from forming burns to the skin. Moreover, the radiator is located in the rear lampshade 23, and the heat generated by the micro LED lamp is diffused to the outside through the radiator and the heat dissipation holes.

[0044] When performing breast or thyroid surgery, the light intensity can be changed at any time as needed, so that the appropriate light can be selected to increase positioning accuracy.

[0045] Specifically, the strip body 10 is provided with a plurality of through holes 11; each rear lamp cover 23 passes through the through hole 11, and a heat dissipation hole is provided on the portion of the rear lamp cover 23 located outside the through hole 11. The heat dissipation hole can accelerate the heat dissipation of the light source to avoid burning the skin. Moreover, through the mutual cooperation between the rear lamp cover 23 and the through hole 11, on the one hand, the specific position of each lamp body 20 can be limited to ensure that the plurality of lamp bodies are evenly distributed; on the other hand, the connection between the lamp body 20 and the strip body 10 can be made more firmly.

[0046] For example, Figure 4 As shown, the cross section of the strip body 10 is arc-shaped, and the inner space of the arc is the lamp body installation space, and the front end of the lamp body 20 protrudes from the installation space. When combined with the lamp body fixing belt 12, the cross section is similar to an "Ω" structure, which can reduce the scattering of light so that the energy of the light source is more concentrated at the predetermined position, thereby improving the positioning accuracy. Moreover, the structure can also protect the lamp body. In addition, the inner surface of the strip body 10 has a light shielding layer, and the light shielding layer cooperates with the "Ω" structure to further reduce the scattering of light.

[0047] Regarding the connection method between the lamp body 20 and the strip body 10, it can be achieved by gluing, and an additional object such as a cover body can be designed on the strip body 10 to fix the two.

[0048] In one embodiment, an adhesive layer 40 is provided on the surface of the lamp body fixing belt 11 facing the predetermined position. The lamp body fixing belt 11 can be attached to the skin at the predetermined position through the adhesive layer 40. In addition, the same isolation paper 30 is attached to the adhesive layers 40 of the two lamp body fixing belts 12, and the isolation paper 30 also covers the installation space.

[0049] The material of the adhesive layer 40 is cloth tape, which has better plasticity than plastic tape, so it is easy to adjust during the adhesive tape sticking process to adapt to the natural contour of the surgical boundary light and the surgical boundary to meet the personalized needs of the patient's surgical boundary.

[0050] The fabric tape is made of black fabric and fits tightly to the outer surface of the micro LED to reduce light scattering. The tape is tightly bonded to the skin at the surgical boundary to fix the micro LED lamp and prevent the direction of the micro LED lamp from changing.

[0051] The adhesive of the tape is a medical grade adhesive with good biocompatibility, non-sensitization, non-irritation and non-cytotoxicity. The size of the isolation paper 30 matches the size of the tape to protect the adhesive layer and prevent accidental adhesion.

[0052] In the present invention, Figure 3 As shown, several lamp bodies 20 are connected to a control device 60 through the same connecting wire 50, and the control device 60 is used to adjust the brightness of the light source 21. The control device 60 is provided with an indication mark 61, a regulator 62 and a variable resistor 63. The connecting wire 50 is a soft wire, which can be matched with a strip body to change the shape and adapt to the position of the surgical boundary.

[0053] The light source uses an analog dimming format to adjust the light intensity. The resistance of the light source is set as a variable resistor 63. The light source is provided with a regulator 62 that can adjust the resistance. The light source adjusts the variable resistor 63 through the regulator 62 to change the current, thereby adjusting the intensity of the LED light.

[0054] Furthermore, in order to meet the diversity of different patient body shapes and tissue thicknesses, as well as the different tissue thicknesses at different surgical levels, the brightness of the micro-LED lamp is optimized through the regulator to ensure that the light can penetrate different tissue thicknesses. By finely adjusting the intensity of the light, the micro-LED lamp can project clear and discernible small dots, which are formed by the joint action of multiple micro-LED lamps to form a coherent "dotted line" to show the boundaries of the surgery, thereby realizing personalized adjustment of the positioning of the surgical boundaries.

[0055] Take breast surgery as an example. In breast laparoscopic surgery, although there is an imaging device at the front end of the laparoscope, since the breast is filled with glands and fat, when the laparoscope enters the breast, the imaging device is located in the glands and fat. Therefore, during the process of freeing the breast (i.e. separating the breast from the skin flap / pectoralis major muscle), it is difficult to distinguish the position of the imaging device in the gland, that is, it is difficult to distinguish whether it has been freed to the predetermined position, which will cause the freeing to exceed the predetermined position or fail to reach the free position. This is similar to a diver diving in the sea. Without external assistance, it is difficult to judge his own position. When he swims out of the water, he finds that he is offset from the ship.

[0056] In the present invention, a limit positioning device is set at the skin at a predetermined position, and the device emits a light beam to the skin. The light beam passes through the skin and shines into the gland, leaving an obvious mark. When the freeing reaches the light beam, it can be determined that the predetermined position has been reached and the freeing can be stopped, thereby improving the accuracy of the operation.

[0057] In summary, precise positioning and visualization assistance can help surgeons achieve better surgical results in different operations, thereby meeting patients' high standards for surgical quality and postoperative recovery.

[0058] As a specific embodiment, the use of the device of the present invention during laparoscopic mastectomy and breast reconstruction is described below.

[0059] First, use a marker pen to outline the location of the surgical boundary with the patient in a standing position.

[0060] Next, after the patient is anesthetized and disinfected, the isolation paper is removed and the sterilized limit positioning device is attached to the position marked before the operation. Figure 5 During the operation, the appropriate brightness is selected according to the patient's tissue thickness to ensure that the LED light can project clear and discernible dots. These dots are formed by the joint action of multiple LED lights to form a coherent dotted line, showing the boundaries of the operation;

[0061] Then, according to different surgical levels, the light intensity is adjusted at any time to ensure that the surgical boundaries are clearly visible. Finally, the boundary positioning device can be removed after the dissection of the surgical boundaries is completed.
