Guide device of round tubular binding instrument

Abstract

The invention provides a guide device of a round tubular binding instrument. The round tubular binding instrument comprises an anvil component, a nail bin component, a bent tube fixed at the near end of the nail bin component and an anvil draw bar which is movably disposed in the nail bin component and is used for being connected with the anvil component, the guide device comprises an elastic round tubular body which covers the outer periphery of the nail bin component, the body is provided with a round hole at the center of the far end, the guide device can move between the far end of the nail bin component and the near end of the nail bin component, an operator can insert the nail bin component in a structure more smoothly due to the outer surface of a smooth moving section, and the structure can be prevented from damage due to an oversize end face of the nail bin component. The guide device of the round tubular binding instrument is simple in manufacture, low in cost and worthy of being widely popularized and applied.

Description

technical field [0001] The invention relates to an operation auxiliary part of a circular tube binding instrument, in particular to a guiding device of a circular tube binding instrument. Background technique [0002] The circular tubular stapler is a surgical instrument widely used in digestive tract reconstruction surgery. It consists of a circular nail head assembly and a firing assembly; two sections of circular tubular tissue that need to be connected are placed on the anvil of the nail head assembly Between the staple cartridge and the staple anvil, adjust the distance between the staple anvil and the staple cartridge to gradually clamp the tissue, and then operate the firing component to shape the staple 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 f...

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 not smooth enough, it is easy to cause damage to the mucous membrane when passing through the inside

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