Description

Technical Field

[0001] The present invention relates to the field of laser surgical equipment, and more specifically to a laser optical fiber manipulator.

Background Art

[0002] Lasers can be used not only to remove skin, masses, etc. on the body surface due to their high efficiency, accuracy, and excellent cutting and hemostasis effects, but in recent years, they have gradually been used in laparoscopic visceral surgery. As a new technology, they tend to replace traditional scalpels. With the development and application of laser optical fibers of various different wavelengths, the scope of clinical application of future laser medicine will become increasingly wide.

[0003] However, there is currently no dedicated laser optical fiber operating instrument in clinical laparoscopic surgery. Therefore, when some doctors try to use a laser optical fiber for surgical treatment in laparoscopic surgery, they can only operate the laser optical fiber by borrowing some temporary operating levers, which is very inconvenient to use and also exposes many problems as follows.

[0004] 1. Due to the high energy of the laser optical fiber, it is necessary to continuously cool it with water during the operation to reduce wound eschar formation.

[0005] 2. Based on the above, when the laser optical fiber removes organs or human tissues, it generates a large amount of smoke, which blurs the operation vision and needs to be discharged in a timely manner. However, in laparoscopic surgery, due to the establishment of pneumoperitoneum pressure, if there is air leakage or the suction position is not accurate and timely, excessive gas will be aspirated while ensuring the purpose of suction, resulting in a rapid decrease and instability of the pneumoperitoneum pressure, affecting the operation space of the surgery and hindering the accurate operation of the surgery.

[0006] 3. Based on the above, in order to achieve suction and cleaning, it is necessary to make two additional incisions in the patient's skin and increase two laparoscopic operating trocars, which increases the surgical cost. Furthermore, in clinical operations, at least one assistant needs to be added to assist with continuous water injection during the operation for cooling and the use of a suction device to extract blood and smoke.

[0007] Therefore, in summary, not only does the comfort and efficiency of the surgery decrease significantly, but also the number of skin incisions and the use of surgical consumables increase, which severely limits the wide application of laser surgery.

[0008] In view of the above problems, a laser fiber manipulator is designed.

Embodiments for Carrying Out the Invention

[0024] The above solutions will be further described below with reference to specific embodiments. It should be understood that these embodiments are for explaining the present invention and do not limit the scope of the present invention. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally the conditions in general experiments.

[0025] In a specific embodiment, a laser fiber manipulator is provided. Specifically, A first guide tube 10, a second guide tube 11, and a third guide tube 12 that can be introduced into the abdominal cavity, and a first tube sleeve 1 for attaching and fixing the three guide tubes. Here, the first tube sleeve 1 corresponds to a mounting base, and the three guide tubes are attached to its front end, and a front-end drainage channel is constructed between the three guide tubes, that is, it includes a third channel P3, a second channel P2, and a first channel P1.

[0026] In addition, the operating device further includes a second tube sleeve 2 and a third tube sleeve 4 attached to the rear end of the first tube sleeve 1. A rear-end drainage cavity, that is, a first back cavity C1 and a second back cavity C2, is formed between the two, and control valves corresponding to the two cavities are communicated to control the cleaning amount and the suction amount.

[0027] To realize the cleaning and suction functions, the front-end drainage channel and the rear-end drainage cavity are installed in communication.

[0028] A fourth casing 5 and a fifth casing 6 are further installed at the rear end of the operating device. The fifth casing 6 is screwed to the rear end of the third tube sleeve 4, and the fourth casing 5 is screwed or inserted into the rear end of the fifth casing 6. Here, the fourth casing 5 is mainly used for attaching or fixing the rear end of the optical fiber a. It can ensure that the front end of the optical fiber a is installed along the inside of the guide tube and the stable installation of the optical fiber a. Also, it is used as a handle of the operating device during operation to facilitate surgical operations. The fifth casing 6 is mainly used for sealing the connection part of the rear end of the optical fiber a to avoid liquid leakage from the end of the fourth casing 5. Here, a gasket 14 is installed at the front end of the fifth casing 6, and a waterproof cap 15 is installed at the rear end of the fifth casing 6. Both are made of only elastic rubber material, and the optical fiber a can penetrate both of them in a sealed manner. It can be seen that the gasket 14 and the waterproof cap 15 correspond to a two-layer seal, further improving the sealing effect. Based on this, an elastic tail cap 16 is installed at the end of the fourth casing 5 to support the rear end of the optical fiber a and avoid the optical fiber a being greatly bent and damaged.

[0029] In order to realize the installation and arrangement of the optical fiber a, in this embodiment, the optical fiber a is installed on the axis of the operating device and extends from the front end to the rear end. The optical fiber at the front end is used for cutting, and the optical fiber at the rear end is connected to the laser generator.

[0030] As described above, the specific structure and connection form of this embodiment are as follows.

[0031] A front channel 1.4 for drilling the optical fiber a is penetrated and installed on the axis of the first tube sleeve 1. Generally, a gap is left between the optical fiber a and the front channel 1.4 after the optical fiber a is drilled, which is used for the cleaning liquid to pass through. Therefore, in this embodiment, since the optical fiber a and the front channel 1.4 are closest to each other, the front channel 1.4 is mainly used to discharge the cleaning liquid to clean and cool the cutting location.

[0032] In order to realize the entry of the cleaning liquid, a first connection port 1.6 communicating with the front channel 1.4 is opened on the side wall of the first tube sleeve 1, and a second rotary valve 9 is attached to the first connection port 1.6 to control the conduction, interruption, and cleaning flow rate of the cleaning liquid. Here, generally, a ball valve is selected for the second rotary valve 9. In this embodiment, the second rotary valve 9 can realize the normally open and normally closed effects of the corresponding channels.

[0033] In this embodiment, the first guide tube 10, the second guide tube 11, and the third guide tube 12 are coaxially attached to the front end of the first tube sleeve 1 and are arranged and installed in sequence from the outside to the inside. Here, a third channel P3 is formed between the first guide tube 10 and the second guide tube 11, a second channel P2 is formed between the second guide tube 11 and the third guide tube 12, the inside of the third guide tube 12 is the first channel P1, and the first channel P1 communicates with the front channel 1.4 to realize the introduction of the cleaning liquid into the cutting tissue.

[0034] As a preferred embodiment of the above-described embodiment, in order to facilitate the mounting stability and sealed connection of each guide tube, first ring grooves 1.1, 1.2, and third ring groove 1.3 are respectively formed at the front end of the first tube sleeve 1, and are arranged and installed in order from the outside to the inside along the radial direction of the first tube sleeve 1. The first guide tube 10, the second guide tube 11, and the third guide tube 12 are attached to the corresponding ring grooves according to the arrangement order from the outside to the inside. Therefore, the end of the guide tube can be restricted and fixed by the groove. Specifically, screw connection or tight fitting with the groove should be adopted.

[0035] Here, in this embodiment, the third channel P3 is mainly used for sucking smoke, and the second channel P2 is mainly used for sucking the cleaning liquid.

[0036] To achieve rear-end drainage, the specific connection structure at the rear end of the manipulator is as follows.

[0037] The second tube sleeve 2 is screwed to the rear end of the first tube sleeve 1. Here, the screwing is for realizing the diversion, and generally it is a sealed connection. Also, to achieve outward drainage, similarly, a second connection port 2.1 is formed on the side wall of the second tube sleeve 2, and a first rotary valve 8 is attached to the second connection port 2.1. A ball valve can be selected, and the normally open and normally closed effects of the corresponding channel can be realized.

[0038] To construct a rear-end drainage cavity, a third tube sleeve 4 is further included, and an extended connecting tube 4.1 is installed at its front end. The main function of the extended connecting tube 4.1 is to form a fitting structure with the second tube sleeve 2.

[0039] Specifically, the front end of the extension connection pipe 4.1 is hermetically connected to the first pipe sleeve 1, and the rear end of the extension connection pipe 4.1 is screwed to the rear end of the second pipe sleeve 2, and the screwing here is also a hermetic screw connection. In this way, a first back cavity C1 for guiding the flow between the extension connection pipe 4.1 and the second pipe sleeve 2 is formed, and a second back cavity C2 is formed inside the extension connection pipe 4.1. The two form independent cavities without communicating with each other, and each forms a drainage channel to facilitate drainage control.

[0040] As a preferred embodiment of the above embodiment, in order to realize the positioning of the extension connection pipe 4.1 and the hermetic connection with the rear end of the first pipe sleeve 1, a fourth ring groove 1.5 is opened at the rear end of the first pipe sleeve 1, and an elastic rubber ring is installed at the groove bottom. After installation, if the extension connection pipe 4.1 is inserted into the fourth ring groove 1.5 and abuts against the elastic rubber ring, end sealing can be realized.

[0041] As a preferred solution of this embodiment, as can be seen from the above, the second pipe sleeve 2 is screwed to the rear end of the first pipe sleeve 1, and the rear end of the extension connection pipe 4.1 is screwed to the rear end of the second pipe sleeve 2. Since the first pipe sleeve 1 all adopts screwing, when installing, in order to ensure that the thread reaches the sealing requirement at the installation positions of the first rotary valve 8 and the third connection port 4.4 at the same time, an intermediate sleeve 3 is adopted to avoid the synchronous rotation of the second pipe sleeve 2 and the extension connection pipe 4.1 when screwing in. The specific structure is as follows.

[0042] A conical thin-wall engagement ring 4.11 is installed on the peripheral wall of the extension connection pipe 4.1. A plurality of opening grooves are installed on the ring wall. Since the thin-wall engagement ring 4.11 compresses and deforms the opening grooves, the intermediate sleeve 3 is hermetically fitted and installed from the small-diameter end of the engagement ring 4.11 to the rear end of the extension connection pipe 4.1. For sealing here, a sealing ring is usually installed inside the intermediate sleeve 3, and the sealing ring can achieve a moving sealing connection with the extension connection pipe 4.1. An abutting slot 3.1 is installed on the intermediate sleeve 3, with a thread installed inside it and screwed to the second pipe sleeve 2. Therefore, the rotation of the extension connection pipe 4.1 is avoided, and the rotation of the intermediate sleeve 3 is used to propel the movement of the extension connection pipe 4.1, further improving the convenience of use.

[0043] Here, the drainage connection method at the front and rear ends is that the second channel P2 communicates with the second back cavity C2, and the third channel P3 communicates with the first back cavity C1.

[0044] Also, as can be seen from the above, since the front channel 1.4 is mainly a cleaning channel, in order to prevent the cleaning liquid from entering the second back cavity C2, the communication location between the front channel 1.4 and the second back cavity C2 is sealed by a sealing plug 13. In this embodiment, since the optical fiber a can penetrate through hermetically, generally the sealing plug 13 is made of a rubber material, and the optical fiber a can penetrate through the sealing plug 13 in a sealed and sliding manner. Specifically, a plurality of sealing rings are installed inside the hole that fits with the optical fiber a, and the sealing rings are connected to the outer wall of the optical fiber a, which belongs to the conventional movable sealing form, such as valve rod sealing, and the description is omitted here.

[0045] Similarly, in order to achieve the outward conduction of the second back cavity C2, a third connection port 4.4 is installed on the third pipe sleeve 4, and a pressing valve is attached to the third connection port 4.4. This pressing valve generally refers to a valve that conducts and interrupts in a pressing form and belongs to the pressing control valve. When in use, the conduction and interruption of the valve can be controlled in a form of pressing with a finger, realizing intermittent suction and improving the convenience of use.

[0046] Also, the second channel P2 may be used as a cleaning channel. When in use, the cleaning liquid is discharged from the through hole in the front-end peripheral wall of the third guide tube 12, and auxiliary cleaning can be performed. Moreover, by combining the control of the pressure valve, intermittent cleaning can be realized, improving the convenience of use.

[0047] As a preferred embodiment, to realize the selection of the suction or cleaning function of the second channel P2, the third connection port 4.4 includes a first branch port 4.41 and a second branch port 4.42, and both communicate with the second back cavity C2 respectively. To realize the intermittent control of the suction or cleaning of the second channel P2, it is controlled by two pressure valves, namely the first pressure valve 4.2 and the second pressure valve 4.3. The first pressure valve 4.2 controls the conduction and interruption of the first branch port 4.41, and the second pressure valve 4.3 controls the conduction and interruption of the second branch port 4.42. Therefore, different cleaning pumps or suction devices may be connected corresponding to the first branch port 4.41 and the second branch port 4.42 during use.

[0048] During specific clinical use, first connect each valve to an external device, that is, communicate with the corresponding abdominal pressure suction device and water supply pump. Further, insert the optical fiber a from the rear end of the operating device and extend it to the front end of the operating device for tissue cutting. During use, introduce the first guide tube 10, the second guide tube 11, and the third guide tube 12 into the abdominal cavity through the channel established by the abdominal cavity, and reach the affected part with the cutting end of the optical fiber a under the visual guidance of the endoscope, and perform cutting. At the same time, open the second rotary valve 9 to supply the cleaning liquid, and the cleaning liquid passes through the first channel P1 and is introduced to the front end of the optical fiber a for cleaning and cooling. Since there is smoke during cutting, the first rotary valve 8 can be opened at this time to continuously generate a slight negative pressure in the third channel P3, and suck the smoke when ensuring that the pneumoperitoneum pressure is stable. Also, when it is necessary to suck the cleaning liquid, the cleaning liquid can enter from the second channel P2 and be collected by controlling the pressure valve.

[0049] Therefore, cutting, washing, liquid suction, and smoke suction are all arranged on the same operating instrument, and the surgeon can perform the above operations with one hand. By attaching the optical fiber a to the pen-shaped operating instrument, the extraction and control of the optical fiber can be facilitated.

[0050] In this case, the third channel P3 and the second channel P2 generally have a small channel cross-section, and in this way, it is possible to avoid a rapid decrease in the pneumoperitoneum pressure during suction.

[0051] Also, as can be seen, since both the cleaning end and the suction end are installed around the cutting location of the optical fiber a, cleaning and suction can be achieved quickly and efficiently. Especially when sucking smoke, accurate and rapid suction can be performed when the smoke is not fully diffused, avoiding over-suction and suction leakage, ensuring that the pneumoperitoneum pressure fluctuates stably, improving the visual effect, and enhancing the surgical efficiency and safety.

[0052] Moreover, the cutting, cleaning, and suction functions are all integrally installed, which can reduce the opening in the patient's abdomen and the use of medical instruments, reduce the patient's injury, and reduce the medical cost.

[0053] Combining the above embodiments, during the operation, to further improve the surgical field of view and make it easier for the surgeon to observe the position of the optical fiber a, the front end of the third guide tube 12 is installed protruding from the front end of the second guide tube 11, and the front end of the second guide tube 11 is installed protruding from the front end of the first guide tube 10. That is, a stepped shape is formed at the front end of the operating instrument. In this way, the first guide tube 10 and the second guide tube 11 can each reduce the blockage to the optical fiber a, improve the accuracy of cutting, and further enhance the surgical safety.

[0054] To further improve the suction and cleaning efficiency and range, through holes are opened in both the front end peripheral wall of the first guide tube 10 and the front end peripheral wall of the third guide tube 12. Here, the through hole in the front end peripheral wall of the third guide tube 12 extends to the inside of the second guide tube 11.

[0055] When specifically used, since the first guide tube 10 is the main smoke suction channel, the smoke diffused through the through holes on the front end side wall can be introduced to improve the suction efficiency. In addition, since the front end of the third guide tube 12 protrudes the most, when the second channel P2 sucks, it can suck through the through holes on the peripheral wall of the front end of the third guide tube 12, improving the suction efficiency and avoiding large blood clots from entering the second channel P2 to a certain extent.

[0056] Combining the above solutions, in order to realize the telescopic control of the optical fiber a for application to cuts at different positions during the surgical operation, a mechanism for controlling the movement of the optical fiber a is installed in the fourth casing 5, specifically as follows.

[0057] An attachment port 5.1 is opened on one side of the fourth casing 5, and a button 7 that can reciprocate along the axis of the fourth tube sleeve 5 is installed in the attachment port 5.1. One end of it is arranged outside the attachment port 5.1, the other end is arranged inside, and a clamp port 7.1 is installed at this end. The clamp port 7.1 can clamp the optical fiber a. Furthermore, when the button 7 is pressed during use, the telescopic movement of the front end of the optical fiber a can be realized. Similarly, in order to realize that the fourth casing 5 is slidably connected to the optical fiber a, a gasket 14 is installed at the front end of the fourth casing 5, and the optical fiber a is hermetically and slidably inserted into the gasket 14.

[0058] Based on this, to further realize the positioning of the optical fiber a and avoid its movement during cutting, a stopper plate 5.2 is installed inside the attachment port 5.1, and a slot is formed with the edge of the attachment port 5.1. In addition, a wing plate 7.2 is installed on the peripheral wall of the button 7 and inserted into the slot. And a dome 5.3 that can contact the wing plate 7.2 inside the slot and press and repel the button 7 is installed.

[0059] In addition, a plurality of concave grooves 5.4 are arranged and provided on the inner edge of the mounting port 5.1. At the same time, bumps 7.3 are provided on the wing plate 7.2, and the bumps 7.3 are arranged in the concave grooves 5.4 to realize the positioning of the button 7. When specifically used, the button 7 is pressed to disengage the bump 7.3 from the concave groove 5.4, realizing the front-back sliding of the button 7 within the mounting port 5.1, further driving the telescopic movement of the optical fiber a. After determining the position of the cutting end of the optical fiber a, the button 7 is released, and the elastic force of the dome 5.3 causes the bump 7.3 and the concave groove 5.4 to fit together to limit the button 7, further realizing the positioning of the optical fiber a.

[0060] To sum up the above, in order to more easily clamp the optical fiber a, a crack 7.4 penetrating the clamping port 7.1 is provided on the contour edge of the clamping port 7.1. The crack 7.4 generates elasticity in the clamping port 7.1. When installing, by opening the crack 7.4, the optical fiber a can be smoothly passed through the clamping port 7.1. After determining the clamping position, the crack 7.4 is released to clamp the optical fiber a in the clamping port 7.1. Therefore, the convenience of installation can be improved.

[0061] Taking the above ideal embodiments based on the present invention as a revelation, through the above description, those skilled in the art can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content described in the specification, and it is necessary to determine its technical scope based on the scope of the claims.
