Anorectal surgery assisting device

technical field

The invention relates to the technical field of medical instruments, in particular to a purse string suture device.

Background technique

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 operation; and because the operation not only resects the rectal mucosal prolapse band, but also blocks the terminal anastomotic branch of the terminal rectal artery and vein, eliminating the The root cause of hemorrhoids has a very ideal therapeutic effect on internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, circular hemorrhoids, severe hemorrhoid prolapse, and rectal prolapse. It has the characteristics of quick effect, quick recovery and no pain after operation.

In the PPH operation, the purse bag is a key step, and the quality of the purse bag is related to the success of the whole operation. Currently, the purse bag is usually performed manually with a suturing device and a sewing needle. During the operation, the introducer is used first. Guide the anal dilator into the affected area, and then insert the suturing device into the anal dilator for pocketing.

Patent CN201310752926.1 discloses an auxiliary device for non-circular cutting hemorrhoid surgery. This device has a suturing device, anal expander, and introducer as an integrated structure. The side wall of the auxiliary device has one or more openings. Opening, in the operation, according to the size of hemorrhoids of different patients, the size of the opening on the instrument needs to be different.
