[0002] During human surgery, lesions in the human body need to be removed, and during the removal process, normal organs need to be separated and protected. Therefore, laparoscopic surgery is used. Separation forceps are often used to separate tissues in laparoscopic surgery. The simple principle is to use the blunt clamped forceps head to insert into the soft tissue around the organ, and then open the forceps head to separate the tissues on both sides of the forceps head to achieve the purpose, avoiding the risk of cutting and damaging organs and surrounding blood vessels caused by direct cutting with a knife.

In addition, the soft tissues on the back of such organs are thick and rich in microvessels. It is often difficult to deeply separate the soft tissues on the back and free these organs. The risk of vascular damage also makes it impossible to quickly locate the appropriate separation position, and it is not easy to use an electric knife to quickly cut and separate. Therefore, how to safely, effectively, conveniently and quickly separate the soft tissues on the back of fixed organs is an urgent problem to be solved. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] The utility model aims to provide a laparoscopic separation forceps which has a simple structure and meets the functional requirements of safely, effectively, conveniently and quickly separating the dorsal soft tissue of an organ with a fixed position.

[0023] Based on this, an embodiment of the utility model provides an arc-shaped laparoscopic separation forceps with a positioning light, including a fixed handle 1 and a movable handle 2, the fixed handle 1 is hinged to the upper part of the movable handle 2, the upper part of the movable handle 2 is connected to a hollow clamp rod 3, an arc-shaped rubber hose 4 is arranged inside the front end of the hollow clamp rod 3, and a traction component fixedly connected to the arc-shaped rubber hose 4 through the inside of the hollow clamp rod 3 is arranged on the upper part of the fixed handle 1, and the traction component is adjusted to make the arc-shaped rubber hose 4 extend out of the hollow clamp rod 3 or retract inward; a clamp 5 is arranged at the front end of the arc-shaped rubber hose 4, and the clamp 5 includes a movable clamp leaf 501 and a fixed clamp leaf 502, and the rear end of the movable clamp leaf 501 and the rear end of the fixed clamp leaf 502 are located in the arc-shaped Inside the hose 4, the rear end of the movable clamp leaf 501 is rotatably connected to the front end of the arc-shaped hose 4, and the rear end of the movable clamp leaf 501 is connected to the movable handle 2 through the pulling assembly 6. When the movable handle 2 rotates, it drives the movable clamp leaf 501 to rotate, forming an open state or a closed state between the movable clamp leaf 502; a positioning light 7 is provided at the opening of the clamp 5, and the fixed clamp leaf 502 is hollow inside, forming an internal channel with the hollow clamp rod 3 and the fixed handle 1. The positioning light 7 is connected to a matching circuit, which is installed in the internal channel on the fixed handle 1, and is electrically connected to the positioning light 7 through a circuit set through the internal channel on the hollow clamp rod 3. The matching circuit includes a battery 8 and a control switch 9.

[0024] The arc-shaped laparoscopic separation forceps with a positioning light of the utility model optimize the combination of the arc-shaped rubber tube 4, the positioning light 7 and the laparoscopic separation forceps, so that the clamp 5 can not only better fit cylindrical organs such as the esophagus through the arc-shaped rubber tube 4, but also can be quickly positioned by the positioning light 7, cooperate with the electric knife to open the tunnel, avoid blood vessel damage to the greatest extent, and perform separation in depth, meet the functional requirements of safely, effectively, conveniently and quickly separating the dorsal soft tissue of the fixed-position organ, facilitate the next step of the operation, speed up the progress of the operation, reduce patient damage, and have strong practicality.

[0025] In the embodiment of the utility model, the size of the arc-shaped rubber hose 4 is not specifically described. Optionally, the cross-section of the arc-shaped rubber hose 4 is a quarter arc with a radius of 1-3 cm, and as an example, the radius is 2 cm. A quarter arc with a radius of 2 cm has obvious advantages in the process of using the separation forceps for tissue separation. The design takes into account a closer fit with the cylindrical organ, so that the separation forceps can better adapt to the cylindrical structure, especially when dealing with organs such as the esophagus, which helps to minimize interference with surrounding tissues, reduce the risk of complications during surgery, and improve the accuracy of surgery.

[0026] Preferably, a rod seat 10 is provided at the front end of the fixed handle 1 , a rotating handle 11 is mounted on the rod seat 10 , a connecting cap 12 is fixed to the front end of the rotating handle 11 , and the hollow clamp rod 3 is fixed on the connecting cap 12 .

[0027] Specifically, the rod seat 10 can increase the stability of the entire structure, making it difficult for the movable handle 2 to loosen or shift during use. At the same time, the modular design facilitates the maintenance and replacement of parts. If a part needs to be repaired or replaced, the operation can be performed more conveniently without having to replace the entire surgical forceps.

[0028] Preferably, a movable joint 13 is fixed inside the front end of the arc hose 4, the movable joint 13 is rotatably connected to the movable clamp leaf 501, the fixed clamp leaf 502 is arranged through the movable joint 13, and its front end extends out of the arc hose 4, and its rear end is located in the arc hose 4.

[0029] The movable clamp blade 501 is connected to the pulling assembly 6 through the movable joint 13, so that the movable clamp blade 501 The opening and closing action is smoother, reducing the resistance and friction during operation, thereby improving the efficiency and accuracy of the operation. The pulling component 6 controls the movable forceps leaf 501, so that the movable forceps leaf 501 can adapt to tissues and organs of various sizes and shapes and accurately adjust the opening degree of the movable forceps leaf 501.

[0030] Preferably, the fixed handle 1 and the movable handle 2 are hinged via a rotating shaft.

[0031] The joint design of the hinge enables it to maintain a stable posture and position, providing greater operational control and accuracy. Doctors can achieve fine control of surgical instruments by adjusting the degree and angle of the joint, which helps to perform precise tissue cutting, suturing and other surgical steps.

[0032] Preferably, it further comprises a baffle 14 fixedly arranged inside the hollow clamp rod 3 , and when the arc hose 4 is completely retracted inside the hollow clamp rod 3 , the front end surface of the baffle 14 abuts against the rear end surface of the arc hose 4 .

[0033] The baffle 14 is an important accessory, which plays an important role in the process of the traction component retracting the arc hose 4. When the traction component retracts the arc hose 4, the baffle 14 can firmly support the arc hose 4 to ensure that it will not move or slide at will.

[0034] Preferably, the traction assembly includes a steel wire 15 and a gear 16, the gear 16 is rotatably connected to the upper side of the fixed handle 1 near one end of the movable handle 2, a plurality of holes are provided on the baffle 14, one end of the steel wire 15 is fixedly connected to the rear end of the arc-shaped hose 4, and the other end passes through one of the holes on the baffle 14 and is wrapped around the gear 16.

[0035] In the embodiment of the utility model, the material of the steel wire 15 is not specifically limited. Preferably, the material of the steel wire 15 is spring steel wire. The spring steel wire is made of high-strength alloy steel or carbon steel, which usually has a high hardness, so that it can maintain a certain rigidity and stability when straightened. At the same time, the spring steel wire can also show good fatigue resistance under the conditions of repeated bending and stretching.

[0036] The traction assembly composed of the steel wire 15 and the gear 16 can ensure long-term stable operation, especially in an environment of frequent operation. The strength and wear resistance of the steel wire 15 and the precision manufacturing of the gear 16 can greatly improve the reliability and durability of the equipment.

[0037] Preferably, the positioning lamp 7 is a shadowless lamp.

[0038] The shadowless lamp provides higher brightness and better contrast, which helps doctors see the patient's tissue structure more clearly during surgery, reduces color distortion, and makes the color of the tissue more realistic and accurate. In addition, since most of the soft tissue is fat and blood vessels, white light will turn into red light if it passes through blood vessels. At this time, the separation forceps must be moved to a location with thinner and fewer blood vessels to make a tunnel for quick positioning.

[0039] The specific use of the arc-shaped laparoscopic separation forceps with a positioning light in the embodiment of the utility model is as follows: conventionally separate the dorsal tissues such as the esophagus or rectum, start with blunt separation from the soft tissue on the left side of the esophagus (the forceps are clamped and poked between the tissues, and then opened to separate the tissues to both sides), and then separate along the esophageal wall to the back side until the rubber tube reaches the end and it is difficult to separate it further. The length of the forceps head is not enough to completely bypass the esophagus and separate all the tissues. At this time, use force to push the remaining dorsal soft tissue of the esophagus from the left to the right as much as possible, then turn on the high-brightness positioning light 7 and fix it, then turn the laparoscopic field of view to the right, observe the translucent white light spot on the soft tissue around the right esophagus as the positioning of the forceps head, and after determining to avoid the large blood vessels, use the electric knife to cut at this point until the separation forceps position is broken, thus completing the posterior esophageal tunnel. Subsequently, surgical sutures can be used to pass through the tunnel to lift the esophagus, better separate the dorsal tissue, or directly pull it to the left or right to expose the posterior tissue, avoiding damage caused by the method of directly clamping the esophagus with the forceps 5 to force displacement.

[0040] It can be seen that the utility model is an arc-shaped laparoscopic separation forceps with a positioning light. By combining and optimizing the arc-shaped rubber hose 4 and the positioning light 7, the clamp 5 can not only fit the tissue well, but also penetrate deep into the tissue for separation. The positioning light 7 on the fixed forceps leaf 502 helps the electric knife to quickly locate and open the tunnel and minimize vascular damage. The improved laparoscopic separation forceps has both separation forceps and positioning functions, which can conveniently, quickly, safely and effectively separate soft tissue organs in blind spots such as the dorsal side of the esophagus, facilitate the next step of the operation, speed up the progress of the operation, reduce patient damage, and have strong practicality.
