Abstract

The invention relates to an abutting nail piece for a disposable guide type anorectal hemorrhoid anastomat, which is suitable for being matched with the disposable guide type anorectal hemorrhoid anastomat for use. The abutting nail piece is characterized by comprising an abutting nail piece body; multiple dual-hopper-shaped nail slots are arranged on the abutting nail piece body; the inside face of the slot body of each dual-hopper-shaped nail slot is a spherical arc face changing from large to small. The abutting nail piece for the disposable guide type anorectal hemorrhoid anastomat is reasonable in design; the nail slots of the abutting nail piece are set to be dual-hopper-shaped, and the concave area is increased, so nail pins can conveniently slide into the needle slots for molding without easy generating of secondary damages such as tissue exudation; a wound is easy to heal, the pain of a patient is reduced, surgical workload of a doctor is reduced, the surgery is enabled to be smoothly performed and the surgical risk is reduced.

Description

technical field [0001] The invention relates to a one-time guided anorectal hemorrhoid stapler, which is suitable for supporting the use with the disposable guided anorectal hemorrhoid stapler. Background technique [0002] In devices such as medical devices, a disposable guided anorectal hemorrhoid anastomosis is required. [0003] device. Its disadvantages are: because the tissue is squeezed, the nail foot is offset, it is difficult to enter the nail groove to form, the tissue is easy to tear and ooze blood, which is not conducive to wound healing, increases the pain of the patient, and increases the risk of surgery. Contents of the invention [0004] The object of the present invention is to provide a one-time guided anorectal hemorrhoid stapler anvil, the nail groove of the anorectal hemorrhoid stapler is set as a double funnel-shaped nail groove, because the concave area increases, which is conducive to the sliding of the nail foot Formed in the needle groove, it is...
