Linear type anastomat

Abstract

The invention discloses a linear type anastomat of a medical instrument. The linear type anastomat comprises a lower splint, a nail butting base, an upper handle, a lower handle, a percussion mechanism, an opening-closing mechanism and a cutting knife, wherein the upper handle is fixedly connected with the nail butting base; the lower handle is hinged with the nail butting base; the percussion mechanism is arranged on the lower splint and is matched with the lower splint in a slippage way; the opening-closing mechanism is arranged on the lower handle; the opening-closing mechanism can make the lower splint and the nail butting base mutually separated and closed; the head of the lower splint is provided with a nail bin; a nail pushing slice and a suture nail are arranged in the nail bin; the cutting knife is fixedly connected with the percussion mechanism and is matched with the lower splint in a slippage way; the nail pushing slice is fixedly connected with the percussion mechanism and is matched with the lower splint in a slippage way; the nail pushing slice can push out the suture nail in the nail bin; the percussion mechanism comprises a propelling block, a propelling handle, a propelling rod and a safety device; the lower splint is provided with two protruding shoulders; and a sliding groove is arranged between the two protruding shoulders. The linear type anastomat saves labor in the process of percussion, prevents the propelling handle from moving leftwards and rightwards and ensures smooth operations.

Description

technical field

[0001] The invention relates to a stapler for medical instruments, in particular to a linear stapler. Background technique

[0002] Linear stapler is a medical device widely used in digestive tract reconstruction and viscera resection. Some problems, during the firing process of the operating handle, it is necessary to push the propulsion handle forward and apply a large thrust, so the propulsion handle often moves left and right, affecting the normal operation of the operation, and the propulsion block moves in the sliding groove of the lower splint During the process, the friction force is high, which makes it very laborious to operate the push handle to fire. Contents of the invention

[0003] The purpose of the present invention is to provide a linear stapler that saves labor during the firing process and prevents the push handle from moving left and right to ensure smooth operation.
