Anorectal anastomat

Abstract

The invention discloses an anorectal anastomat. The anorectal anastomat comprises a handle seat, a transmission assembly, a percussion assembly and an osculating assembly, wherein the transmission assembly comprises a screw rod arranged in the handle seat and an adjusting mechanism which is arranged at the tail end of the handle seat and connected with the tail end of the screw rod; a nail abutting seat is fixedly mounted at the front end of the screw rod; the percussion assembly comprises a movable handle arranged on the handle seat and a straight push rod arranged on the screw rod in a sleeving manner; and the osculating assembly comprises a nail pushing piece, a nail bin sleeve, a nail bin and an annular knife. The nail pushing piece and the nail bin sleeve adopt triangular support structures, so that the pull-out gap of excised tissue during an operation is increased, and the operation space and the operation view are greatly increased; and meanwhile, the nail pushing piece, the nail bin sleeve and the nail bin are made of metal materials, the rigidity of parts is good, deformation in the operation process is avoided, the anorectal anastomat is convenient to use, and the operation quality is greatly improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an anorectal stapler. Background technique [0002] Anorectal hemorrhoids, commonly known as hemorrhoids, are common and frequently-occurring diseases unique to humans. According to relevant census data, the incidence rate of anorectal diseases is 59.1%, and hemorrhoids account for 87.25% of all anorectal diseases, and among them, internal hemorrhoids are the most common, accounting for 52.19% of all anorectal diseases. Both men and women can get the disease, the incidence rate of women is 67%, and the incidence rate of men is 53.9%. It can occur at any age, and it will gradually increase with age, so there is a saying of "nine hemorrhoids out of ten". [0003] General surgical treatment includes traditional operations such as ligation, rubber band ligation, and hemorrhoidectomy. The operation is troublesome, and the doctor's clinical experience is required during the operati...

During the forming process of the staple, it will produce a reaction force on the push piece, which will compress the height of the plastic part to a certain extent, which affects the consistency of the forming height of the staple. Inner forming, resulting in abnormal situations such as dovetail nails and staples (embedded between the pusher and the staple cartridge), which affect the anastomosis effect
