Embodiment Construction
[0049] The invention provides a purse forming device, which makes it more convenient and quick for doctors to pack a purse, and avoids the time-consuming and labor-intensive problem that doctors use traditional pincers to clamp a sewing needle to make a purse.
[0050] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0051] see Figure 1 to Figure 7, in one embodiment of the present invention, provide a kind of purse bag shaping device, comprise housing and push shaft 3, housing comprises sleeve 2 and guide cap 1 that is releasably connected with sleeve 2, the distal end of sleeve 2 (that is, the connecting end of the sleeve 2 and the guide cap 1) is provided with a plurality of driven wheels 7 spaced apart on the same level (such as figure 2 exemplarily shows six driven whe...

The invention provides a pocket forming device which comprises a housing and a propeller shaft, wherein the housing comprises a sleeve and a guide cap connected with the sleeve in a releasable manner; a plurality of driven wheels are arranged at intervals at the far end of the sleeve; the propeller shaft is positioned inside the housing and can move relative to the housing; a plurality of driving wheels movably connected with the driven wheels are arranged at the far end of the propeller shaft; a plurality of projections are formed at intervals at the end, which is connected with the sleeve, of the guide cap; the inner wall of each of the plurality of projections is provided with at least one guide slots which is segmentally formed; at least one suture needle movably connected with the plurality of driven wheels is arranged in the guide slot; when the driving wheels rotate, the plurality of driven wheels are driven to rotate, so that the plurality of driven wheels drive each suture needles to move in the guide slots. The pocket forming device provided by the invention is simple, rapid and convenient to operate and operation time is shortened.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a purse forming device. Background technique [0002] PPH surgery is also known as "hemorrhoidal circumcision", which is a new technology based on the new understanding of the pathogenesis of hemorrhoids caused by anal cushion lesions. PPH surgery is to use a special instrument called "PPH stapler" to perform circular resection of the prolapsed rectal mucosa above the hemorrhoid. During the operation, the anus is first expanded, and the rectal mucosa is sutured in a circle about 4 cm above the dentate line (the junction line between the rectum and the anal canal), commonly known as "pocket bag", and then the PPH stapler is inserted into the anus. The prolapsed mucosal band is removed, and the whole process only takes about half an hour. Since the rectal mucosa above the dentate line is innervated by visceral nerves, the patient feels almost no pain after the operati...
