Description

Technical Field

[0001] This utility model relates to the field of stapler technology, specifically a novel anorectal stapler. Background Technology

[0002] Anastomosing devices are medical devices used to replace manual suturing. Their main working principle is to use titanium staples to sever or anastomose tissue, similar to a stapler. Depending on their application, they can be mainly divided into skin anastomosing devices, digestive tract (esophagus, stomach, intestines, etc.) round anastomosing devices, rectal anastomosing devices, round hemorrhoid anastomosing devices, circumcision anastomosing devices, vascular anastomosing devices, hernia anastomosing devices, and lung cutting and suturing devices, etc.

[0003] When using existing staplers, it is necessary to suture the mucosa above the hemorrhoids with silk thread, then pull the two ends of the thread out of the anus, tie them together, and hold them with your fingers. This can ensure stable lifting of the tissue and precise resection and staplement. However, when medical staff hold the knotted ends of the thread with their fingers, it increases the difficulty of operating the stapler. Therefore, a new type of anorectal stapler is needed. Utility Model Content

[0004] The purpose of this invention is to provide a novel anorectal stapler that solves the problems mentioned in the background art.

[0005] This application provides a novel anorectal stapler, including a handle. A fixing plate is fixedly connected to the side wall of the handle near the top. Both outer walls of the fixing plate are provided with through-type sliding grooves. The top of the fixing plate is provided with an opening that communicates with the sliding groove. A sliding plate is slidably connected inside the sliding groove. A limit plate is fixedly connected to the outer wall of the sliding plate. A hook is fixedly connected to the outer wall of the sliding plate. A bolt is threaded through the outer wall of the fixing plate and abuts against the sliding plate.

[0006] In use, the cutting head is first extended by using the knob and connecting rod. Then, the cutting head and staple cartridge sleeve are inserted into the patient's anus. Through the groove on the staple cartridge sleeve, external sutures are passed through the sleeve to suture the hemorrhoids around the anus. The two ends of the sutures are then pulled out from the anal edge, tied, and hooked to ensure stable lifting of the hemorrhoid tissue for precise removal and staplering. The prolapsed hemorrhoids are pulled into the staple cartridge sleeve. Then, the titanium alloy staples in the staple cartridge sleeve are triggered by the firing handle to staple the prolapsed hemorrhoids in a ring. Combined with the rotation of the cutting head, the hemorrhoids can be removed. The sliding plate and hook can slide with the cooperation of the groove and opening on the fixed plate, allowing for flexible adjustment of the hook position to accommodate different lengths of suture ends. After adjustment, the sliding plate can be locked with bolts. This frees up the fingers of medical staff and reduces the difficulty of operating the stapler.

[0007] Optionally, the width of the limiting plate is greater than the opening width of the groove.

[0008] By adopting the above technical solution, an effective limiting effect can be achieved, preventing the slide from slipping out of the inside of the groove.

[0009] Optionally, the vertical cross-section of the hook is L-shaped.

[0010] By adopting the above technical solution, the effect of hooking the end of the knotted line can be improved.

[0011] Optionally, the top of the fixing plate is provided with a plurality of threaded holes along the length direction to match the bolts.

[0012] By adopting the above technical solution, it is beneficial to lock the slide after the position has been adjusted.

[0013] Optionally, a tube is fixedly connected to the top of the handle, a staple cartridge sleeve is fixedly connected to the end of the tube away from the handle, a knob is rotatably connected to the end of the handle away from the tube, a connecting rod is fixedly connected to the middle position of the knob, the connecting rod passes through the handle and the tube to the outside of the staple cartridge sleeve and is fixedly connected to the cutting head, and a firing handle is provided at the bottom of the handle.

[0014] By adopting the above technical solution, the cutting head can be extended through the cooperation of the knob and the connecting rod. Then, the cutting head and the staple cartridge sleeve are inserted into the patient's anus in sequence. The prolapsed hemorrhoids are pulled into the inside of the staple cartridge sleeve. Then, the titanium alloy staples in the staple cartridge sleeve are triggered by the firing handle to nail the prolapsed hemorrhoids in a ring. With the rotation of the cutting head, the hemorrhoids can be removed.

[0015] Optionally, the outer wall of the staple cartridge sleeve is provided with a slot.

[0016] By adopting the above technical solution, it is beneficial for the external thread to pass through the groove and suture the mucosa above the hemorrhoid in a circle.

[0017] Optionally, the outer wall of the connecting rod is provided with an annular groove.

[0018] By adopting the above technical solution, slippage of the thread can be prevented.

[0019] Optionally, the hook is made of stainless steel.

[0020] By adopting the above technical solutions, the rust resistance of the hooks can be improved and their service life can be extended.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application uses a hook to catch the knotted tail line, freeing up the fingers of medical staff. With the cooperation of the groove and opening on the fixed plate, the slide and hook can slide, so that the position of the hook can be flexibly adjusted to accommodate knotted tail lines of different lengths. After adjustment, the slide can be locked with bolts. The limiting plate can prevent the slide from falling off the groove. Through the cooperation of the above structures, the difficulty of medical staff operating the stapler is reduced. Attached Figure Description
