Embodiment Construction

[0017] The features of the present invention are described below in conjunction with the accompanying drawings.

[0018] figure 1 It is the section of the present invention, that is, the internal structure diagram, such as figure 1 shown. Part A of the present invention is an umbrella-shaped fixed head end with a constant size, and its umbrella-shaped head end makes the process of placing the present invention in the cavity smooth with little secondary damage; part A is fixedly connected to the central axis and adjacent to part B, which can play a role in pulling Pulling action, assisting part B to scrape off exfoliated tissue. Part B is an adjustable helical expansion arc structure, and its circumference can be adjusted by the rotation of the central axis of part F to fit the tube wall, and can scrape off the tube wall tissue that has been scraped by part D. Part C is made of leaf springs (3 pieces in total), which are distributed in the main part of the present invention ...

Abstract

The invention relates to an adjustable fistula channel curettage device applied to normal anorectal diseases like anal fistula; the adjustable fistula channel curettage device employs circumferential telescopic scrape teeth; a handle is rotated so as to finish a whole fistula channel curettage process; the whole curettage device comprise a head, a body, the handle, and a turn button; the head of the curettage device employs umbrella folding expansion design, and can be adjusted according to the fistula channel sizes; the curettage device body comprises an outer sleeve, a middle layer hidden curet and an inner shaft; the handle is made of medical high-molecular plastic, and the outer layer of which is made of natural rubber, thus complying with human body mechanics design, and the handle is easy to hold; the turn button is made of stainless steel material, and can be tightly combined with the inner shaft of the body, thus realizing accurate adjustments.

Description

Technical field [0001] The present invention is an adjustable fistula tract scratcher (hereinafter referred to as scratcher) applied to anal fistula, a common anorectal disease. The whole scraper consists of four parts: head end, main body, handle and knob. Made of plastic, rubber, stainless steel and other materials. The polymer plastic used in the main body has high thermal stability, good chemical stability, strong elasticity and stretchability, and does not cause inflammation and allergic reactions. The head end of the scraper adopts an adjustable spiral expansion design, which can be adjusted according to the diameter of the human fistula to ensure a close fit with the wall of the fistula, and can remove all the granulation tissue of the tube wall that falls off after scraping at one time. The main part of the scratcher is composed of the outer sleeve, the middle invisible curette and the inner stainless steel shaft: the handle part is designed to meet the requirements o...
