Description

Technical Field

[0001] This utility model belongs to the field of endoscopic surgical clamping forceps technology, specifically relating to a multi-purpose endoscopic surgical clamping forceps. Background Technology

[0002] In maxillofacial endoscopic surgery, due to the small surgical cavity, only one surgeon, besides the endoscopic operator, is allowed to operate with both hands, typically holding a forceps or suction device in the left hand and an ultrasonic scalpel in the right. The left hand must repeatedly change instruments during the procedure, severely impacting surgical manipulation and prolonging the operation time. Traditional endoscopic surgical forceps have a single function, usually only used for clamping or separating tissue. In complex surgeries, surgeons need to frequently change instruments to achieve suction operations, which not only increases surgical time but also may lead to operational risks due to instrument switching. Therefore, there is an urgent need for a compact, multifunctional, and easily adjustable forceps. Utility Model Content

[0003] The purpose of this invention is to provide a multi-purpose clamping forceps for endoscopic surgery to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-purpose endoscopic surgical clamp, comprising a clamp tube, with a rear end sleeve and a front end sleeve respectively provided at both ends of the clamp tube. A connecting rod is connected to a section of the rear end sleeve, and the connecting rod is connected to a handle. A push-pull rod is provided inside the connecting rod. A clamping operating handle is rotatably provided on one side of the handle, and the clamping operating handle is connected to the push-pull rod. The push-pull rod is connected to a transmission rod, and the transmission rod is located inside the clamp tube. A clamp is rotatably provided on the front end sleeve, and the clamp is connected to the transmission rod through a connecting plate. A suction tube is also provided inside the clamp tube. A backing plate is provided on one side of the handle, and a telescopic adjustment rod is rotatably provided on the backing plate. One end of the telescopic adjustment rod is connected to the suction tube.

[0005] Preferably, a connector is provided on the suction tube.

[0006] Preferably, the telescopic adjusting rod is provided with a waist-shaped hole, and a connecting post is provided on one side of the suction tube, with the connecting post disposed inside the waist-shaped hole.

[0007] Preferably, one end of the telescopic adjusting rod is provided with a push-pull crossbar.

[0008] Preferably, the backing plate is provided with an arc-shaped rack, and the telescopic adjustment rod is provided with tooth roots that are adapted to the arc-shaped rack.

[0009] Preferably, a rack groove is formed on the back plate, the arc-shaped rack is movably disposed in the rack groove, and an elastic plate is provided on one side of the back plate, the elastic plate being connected to the arc-shaped rack.

[0010] The technical effects and advantages of this utility model are as follows: by integrating the clamping forceps and the suction tube into one design, the clamping and suction functions are realized, reducing the frequency of instrument changes during surgery, shortening the operation time, and reducing the risk of tissue damage caused by instrument switching.

[0011] The suction tube position is adjustable, allowing for more precise adjustment of the suction position;

[0012] The tooth root of the telescopic adjustment rod engages with the arc-shaped rack to achieve multi-position positioning, and the elastic plate provides elastic locking to prevent the suction tube from accidentally retracting during the operation; pressing the elastic plate can disengage the engagement to achieve stepless adjustment, taking into account both precise positioning and flexible operation.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] This utility model provides, for example Figures 1-3The multi-purpose endoscopic surgical clamp shown includes a clamp tube 1, with a rear end sleeve 2 and a front end sleeve 8 at both ends of the clamp tube 1. A connecting rod 3 is connected to a section of the rear end sleeve 2, and the connecting rod 3 is connected to a handle 4. A push-pull rod 6 is provided inside the connecting rod 3. A clamping operating handle 5 is rotatably provided on one side of the handle 4. The clamping operating handle 5 is connected to the push-pull rod 6, and the push-pull rod 6 is connected to a transmission rod 7. The transmission rod 7 is located inside the clamp tube 1. A clamp 12 is rotatably provided on the front end sleeve 8. The clamp 12 is connected to the transmission rod 7 through a connecting plate 9. When the clamping operating handle 5 is pressed, the upper end of the clamping operating handle 5 moves to the left. The linkage between the push-pull rod 6 and the transmission rod 7 pulls the connecting plate 9, thereby clamping the clamp 12. A single piece is provided between the clamping operating handle 5 and the handle 4 to provide elasticity for the clamping operating handle 5 to reset.

[0020] like Figure 3 and Figure 4 As shown, the clamp tube 1 is also provided with a suction tube 11 inside. The suction tube 11 is provided with a connector 20, which is connected to a negative pressure adsorption device to realize the adsorption function. One end of the suction tube 11 passes through the front sleeve 8. A backing plate 13 is provided on one side of the handle 4. The backing plate is fan-shaped. A telescopic adjustment rod 14 is rotatably provided on the upper end of the backing plate 13. One end of the telescopic adjustment rod 14 is connected to the suction tube 11. By rotating the telescopic adjustment rod 14, the suction tube 11 can be pushed and pulled to adjust the extension position of the suction tube 11, making it more convenient to use.

[0021] As an embodiment of this application, the telescopic adjustment rod 14 is provided with a waist-shaped hole 16, and a connecting post 15 is provided on one side of the suction tube 11. The connecting post 15 is located in the waist-shaped hole 16, and the suction tube 11 and the telescopic adjustment rod 14 are connected through the connecting post 15. The waist-shaped hole 16 provides fault tolerance for the movement of the connecting post 15.

[0022] As an embodiment of this application, one end of the telescopic adjustment rod 14 is provided with a push-pull crossbar 19, which can be rotated in two directions by pressing and hooking with a finger, thereby improving the convenience of operation.

[0023] As one embodiment of this application, a rack groove is formed on the back plate 13, and the arc-shaped rack 17 is movably disposed in the rack groove. The telescopic adjustment rod 14 is provided with tooth roots adapted to the arc-shaped rack 17. An elastic plate 18 is provided on one side of the back plate 13, and the elastic plate 18 is connected to the arc-shaped rack 17. The elastic plate 18 is used to support the arc-shaped rack 17. When the telescopic adjustment rod 14 rotates, the tooth roots on it move on the arc-shaped rack 17, and the arc-shaped rack 17 can retract to one side to facilitate the rotation of the telescopic adjustment rod 14. The elastic plate 18 provides elastic force, which can play a simple locking role. It can also push the elastic plate 18 to separate the elastic plate 18 from the tooth roots of the telescopic adjustment rod 14, so that the rotation of the telescopic adjustment rod 14 is smoother, and the function is diversified.

[0024] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
