Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a novel surgical continuous-firing clip applier and a ligature clip gun box. Background Art

[0002] Surgical ligation technology is an important part of endoscopic surgery. For this reason, people have conducted in-depth research and development on ligation technology, especially in the direction of replacing manual ligation with machines. Due to the outstanding performance of continuous clip applicators in clinical applications, their value can be particularly reflected in emergency bleeding. Various types of continuous clip applicators emerge in an endless stream. In particular, polyoxymethylene (POM) ligation clips are more widely used in clinical applications. Clinicians have proposed whether polyoxymethylene (POM) ligation clips can be designed into continuous types to meet clinical needs.

[0003] Chinese patent CN115670571A discloses a clip bin device and a clip applier, comprising a clip bin for accommodating a plurality of ligation clips, the clip bin having a clip bin bottom plate, at least one boss being arranged in the middle of the left-right direction of the clip bin bottom plate and along the clip delivery direction, when the ligation clip is delivered along the boss, the top of the boss can simultaneously support the tail of at least one ligation clip, so that the plane where the tail of the ligation clip is located is parallel to the plane of the bottom plate of the clip bin, which is conducive to pushing the clip piece to deliver the clip, making the delivery of the clip stable and not prone to the situation of the delivery of the clip being stuck.

[0004] However, the polyoxymethylene (POM) clip of this technical solution is controlled within a certain size range, and permanent deformation is inevitable within a specific time (within 3 years). Existing continuous ligation clip applicators place the ligation clip into the instrument with a large deformation, causing the ligation clip to deform over time and making it impossible to fix the ligation clip on the jaws. Summary of the invention

[0005] The purpose of the present invention is to provide a novel surgical continuous-fire clip applier and ligature clip gun magazine to solve the problem of deformation by cooperating with the nail magazine structure to realize the ligature function.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A novel surgical continuous-fire clip applier and ligature clip gun magazine, comprising a handheld end shell and an operating handle inside the handheld end shell, a body tube is provided on one side of the handheld end shell; a nail magazine tube is installed at one end of the body tube, a material guide bin is installed inside the nail magazine tube, a closing clamp is installed at one end of the material guide bin, and a transmission rod is provided at one end of the inner tube of the body tube.

[0008] A rotating head is arranged on the outer side of the body tube.

[0009] The outer wall of the material guiding bin is provided with a limiting groove.

[0010] A tube body cover strip is installed on the top of the nail box tube.

[0011] A plurality of groups of ligation clip bodies are placed inside the material guiding bin, and the plurality of groups of ligation clip bodies are linearly distributed inside the material guiding bin.

[0012] A transmission mechanism is arranged in the housing of the handheld terminal.

[0013] The transmission mechanism includes a telescopic spring.

[0014] The beneficial effects of the present invention are:

[0015] (1) The present invention discharges the ligation clips through a specific bottom plate in the guide bin in the nail magazine tube, ensuring that the plastic deformation of the ligation clips in a short period of time is minimized, and the clamping structure at one end of the nail magazine tube is connected to the front of the device body tube, thereby greatly improving the practicality of the device and facilitating the user's assembly before use.

[0016] (2) The present invention completes the overall ligation action by pressing the operating handle to pull the connecting piece to drive the transmission rod and the transmission mechanism as well as the opening and closing of the closing clamp and the pushing movement of the ligation clamp body. The upper clamp of the closing clamp is connected to the limiting groove on the side wall of the material guide bin, which will be restricted during the closing action to reduce the maximum opening and closing degree of the jaws, thereby ensuring that the clamped tissue is smoothly placed in the jaws and solving the deformation of the ligation clamp without affecting the elastic deformation capacity of the ligation clamp.

[0017] In summary, the present invention has the advantages of anti-deformation and high practicality. BRIEF DESCRIPTION OF THE DRAWINGS
