Problems solved by technology

However, after the instrument completes a firing action, the operator may unconsciously hold the operating handle again, which is very likely to cause the operating handle to trigger the fired staple cartridge and cutter for a second firing, resulting in medical accidents

Abstract

The invention provides an operating handle and a tubular anastomat with the same, wherein the operating handle is connected with the anastomat body of the tubular anastomat by a pivot; the tubular anastomat comprises a nail pushing rod and a brake pin which are arranged in the anastomat body; the operating handle comprises a contact surface which is selectively contacted with the brake pin; the contact surface is in an L shape, and the L-shaped angle thereof is an acute angle in circular arc-shaped transition; and when the contact surface is contacted with the brake pin, the tubular anastomat is in a secondary percussion prevention state. Compared with the prior art, the operating handle and the tubular anastomat with the same can realize the function of effectively preventing secondary percussion, thus preventing medical accidents.

Description

technical field [0001] The invention relates to an operating handle and a round tubular stapler provided with the operating handle, belonging to the technical field of medical instruments. Background technique [0002] The round tube stapler is a medical device often used in surgical operations on physiological tissues such as the digestive tract. Most of this type of stapler adopts the axial inward binding method. During the anastomosis, the two sections of tissue are restrained and a circular anastomotic ring is formed inside the tissue. Tissues heal relatively easily. [0003] Currently, a circular-tube stapler for treating hemorrhoids includes a stapler body, an operating handle movably connected to the stapler body, and an anvil assembly matched with the body. The stapler body includes an annular staple cartridge and a cutting knife arranged at the distal end. The anvil assembly includes a conical anvil, an anvil cap fixed on the top of the anvil, a knife anvil arran...
