Description

Technical Field

[0001] This utility model relates to the field of suspension clip technology, specifically a suspension clip for laparoscopic cholecystectomy. Background Technology

[0002] Laparoscopic cholecystectomy involves inserting a special catheter into the peritoneal cavity, injecting approximately 2-5 liters of carbon dioxide to achieve sufficient pressure, and then making four small incisions (0.5-1.5 cm) in the abdomen. The Calot's triangle is dissected, the cystic duct and cystic artery are severed and clamped, and the entire gallbladder, including gallstones, is then removed. The conventional four-port method involves inserting four trocars: two for surgical manipulation, one for inserting a camera lens, and one for retracting the gallbladder to expose the surgical field. While this method provides excellent surgical field exposure, it results in more scarring and requires more assistants. Currently, three-port or single-port methods can be used instead of the four-port method for laparoscopic cholecystectomy, reducing the number of incisions and thus minimizing the amount of manipulation.

[0003] Currently, suture suspension is commonly used to improve surgical field exposure. Specifically, sutures are threaded onto the gallbladder and then led out into the abdominal cavity. By pulling on the sutures, the gallbladder can be suspended, exposing the surgical field. However, because the sutures are relatively smooth, they are prone to slipping when being held and pulled, affecting the exposure of the surgical field. Furthermore, suture suspension may perforate the gallbladder wall during suspension, increasing the risk of bile leakage and abdominal contamination. In addition, for a swollen gallbladder in the acute inflammatory phase, the increased tissue fragility means that the tension of the sutures may cut the gallbladder wall, making effective suspension impossible. Utility Model Content

[0004] The purpose of this invention is to provide a suspension clip for laparoscopic cholecystectomy to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suspension clamp for laparoscopic cholecystectomy, comprising a clamp for holding the gallbladder and an arc-shaped support groove, wherein the hinge of the clamp is fixedly connected to one end of a suspension rope, a plurality of spheres are evenly arranged on the suspension rope, the arc-shaped support groove is used to support the suspension rope, and a U-shaped seat is provided on the arc-shaped support groove to limit the position of the spheres, and the arc-shaped support groove is fixedly connected to the edge of the bed through a driving mechanism.

[0006] Preferably, one side of the arc-shaped bearing groove is provided with a connecting block for connecting the drive mechanism.

[0007] Preferably, the driving mechanism includes an electric telescopic rod, the driving end of which is fixedly connected to a connecting block. The electric telescopic rod is detachably mounted on a mounting base. The bottom of the mounting base is fixedly connected to one end of a first connecting pipe. The other end of the first connecting pipe is connected to one end of a metal flexible tube. The other end of the metal flexible tube is connected to one end of a second connecting pipe. The other end of the second connecting pipe is fixedly connected to a fixing frame. A screw is threaded into the fixing frame. One end of the screw is fixedly connected to a clamping plate. The other end of the screw is provided with a knob. By turning the knob, the screw is driven to move the clamping plate to adjust its position within the fixing frame, thereby fixing the fixing frame to the edge of the hospital bed.

[0008] Preferably, the mounting base is provided with a control button for driving the electric telescopic rod to open and close.

[0009] Preferably, the diameter of the sphere is greater than the distance between the inner walls on both sides of the U-shaped seat.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The arc-shaped bearing groove is used to limit the different balls on the suspension rope through the U-shaped seat. The closer the ball is to the clamp, the greater the tension of the suspension rope and the greater the suspension amplitude of the gallbladder. The farther the ball is from the clamp, the smaller the tension of the suspension rope and the smaller the suspension amplitude of the gallbladder.

[0012] 2. The position of the arc-shaped bearing groove can be easily adjusted by the electric telescopic rod and the flexible metal hose, so that the arc-shaped bearing groove can be used for different spheres on the suspension rope. Attached Figure Description

[0017] Example: Please refer to Figures 1-2 This utility model provides a technical solution: a suspension clamp for laparoscopic cholecystectomy, including a clamp 1 for clamping the gallbladder and an arc-shaped support groove 4. The hinge of the clamp 1 is fixedly connected to one end of the suspension rope 2. A plurality of spheres 3 are evenly arranged on the suspension rope 2. The arc-shaped support groove 4 is used to support the suspension rope 2. The arc-shaped support groove 4 is provided with a U-shaped seat 5 for limiting the position of the spheres 3. The arc-shaped support groove 4 is fixedly connected to the edge of the bed through a drive mechanism 6. The position of the arc-shaped support groove 4 is adjusted by the drive mechanism 6 so that the arc-shaped support groove 4 is suitable for different spheres 3 on the suspension rope 2.

[0018] In this embodiment, a connecting block 7 for connecting the drive mechanism 6 is provided on one side of the arc-shaped bearing groove 4.

[0019] In this embodiment, the drive mechanism 6 includes an electric telescopic rod 8. The drive end of the electric telescopic rod 8 is fixedly connected to the connecting block 7. The electric telescopic rod 8 is detachably mounted on the mounting base 9. The bottom of the mounting base 9 is fixedly connected to one end of the first connecting pipe 10. The other end of the first connecting pipe 10 is connected to one end of the metal flexible hose 11. The other end of the metal flexible hose 11 is connected to one end of the second connecting pipe 12. The other end of the second connecting pipe 12 is fixedly connected to the fixing frame 13. The position of the arc-shaped bearing groove 4 can be easily adjusted under the driving action of the electric telescopic rod 8 and the movable adjustment action of the metal flexible hose 11. A screw 14 is threadedly connected in the fixing frame 13. One end of the screw 14 is fixedly connected to the clamping plate 15. The other end of the screw 14 is provided with a knob. By turning the knob, the screw 14 is driven to move the clamping plate 15 to adjust its position within the fixing frame 13, so as to fix the fixing frame 13 to the edge of the hospital bed.

[0020] In this embodiment, the mounting base 9 is provided with a control button for driving the electric telescopic rod 8 to open and close. The opening and closing of the electric telescopic rod 8 can be controlled by the control button.

[0021] In this embodiment, the diameter of the sphere 3 is greater than the distance between the inner walls on both sides of the U-shaped seat 5, so that the U-shaped seat 5 can limit the sphere 3.

[0022] In use, the device is first fixed to the edge of the bed using the fixing frame 13. Then, the clamp 1 is inserted into the abdominal cavity through the surgical operation port or the endoscope port to hold the gallbladder. The free end of the suspension rope 2 extends out of the abdominal cavity and is placed on the arc-shaped support groove 4. The arc-shaped support groove 4 is equipped with a U-shaped seat 5, which is used to limit the different spheres 3 on the suspension rope 2. The closer the sphere 3 is to the clamp 1, the greater the tension of the suspension rope 2 and the greater the suspension amplitude of the gallbladder. The farther the sphere 3 is from the clamp 1, the smaller the tension of the suspension rope 2 and the smaller the suspension amplitude of the gallbladder. The position of the arc-shaped support groove 4 can be easily adjusted by the electric telescopic rod 8 and the metal hose 11 to make the arc-shaped support groove 4 suitable for the different spheres 3 on the suspension rope 2.
