Abstract

The invention provides a guide accessory which is fittingly connected to a circular pipe type binding instrument. The circular pipe type binding instrument comprises a nail anvil component and a nail chamber component. The nail chamber component comprises a nail barrel and a nail chamber which are fixed mutually, the near end of the nail barrel is provided with at least one wire hole, the guide accessory at least comprises a sleeve portion and a guide portion which is a screw part, the sleeve portion is sleeved to the far end of the circular pipe type binding instrument, the guide portion is arranged at the far end of the sleeve portion, the maximum outer diameter of the guide portion is equal to the minimum outer diameter of the sleeve portion, one end of a thread line of the screw part is connected with a traction part, and the other end of the thread line of the screw part is connected with the sleeve portion. The guide accessory has the advantages that one part of the guide accessory can be drawn out of the circular pipe type binding instrument for one time in a strip form, and operations are convenient; and the guide accessory can be directly sleeved outside the circular pipe type binding instrument for use during operation, and no extra part is needed to be assembled for the circular pipe type binding instrument.

Description

technical field [0001] The invention relates to an operation accessory of a circular tube binding instrument, in particular to a guiding accessory of a circular tube binding instrument. Background technique [0002] The circular tubular stapler is a surgical instrument widely used in circular tubular tissue suturing operations. It is composed of a circular nail head assembly and a firing assembly; two sections of circular tubular tissue that need to be connected are placed in the nail head assembly Between the staple anvil and the staple cartridge, adjust the distance between the staple anvil and the staple cartridge to gradually clamp the tissue, and then operate the firing assembly to shape the nail and complete the connection of the two sections of tissue. [0003] In the actual operation, there are two types of operations where it is difficult for the circular tube-type stapler to enter the pipeline, namely, low rectal surgery and gastric bypass surgery. The first type ...

AI Technical Summary

Problems solved by technology

The first type of low rectal surgery uses a circular tube binding instrument with a diameter of 33 mm. The operation needs to be performed through the anus. Since the anus is a muscular opening, its diameter is normally small, and a 33 mm instrument is inserted into the anus. tougher

The second type of gastric bypass surgery uses a circular tube binding instrument with a diameter of 25 mm, which needs to enter the small intestine for surgery. The small intestine is the digestive tract of the human body, and there are many mucous membranes on the inner wall. , and due to structural reasons, the surface is not smooth enough, and it is easy to cause damage to the mucosa when passing through the small intestine

This auxiliary device can help doctors put the staple cartridge assembly into the predetermined position smoothly, but currently this auxiliary device is relatively expensive and cannot be widely provided to the Chinese market
