Problems solved by technology

[0002] In the traditional nasal polypectomy, the operating doctor needs to perform polypectomy in the nasal cavity, and needs to extend the visible tube, ring cutting forceps, cutting forceps, etc. into the nasal cavity. There is no bracket in the traditional nasal polypectomy. During the process, the angle of the nostrils is fixed, which hinders the operation of the tubular instrument, and requires a forceful abutment, which affects the stability of the operation, and the operation space is small

Abstract

The invention discloses a bracket for nasal polyp resection surgery. The bracket comprises a bracket body; the bracket body includes a headrest block and an expansion frame; the expansion frame includes three groups of expansion rods distributed triangularly; the front end of each expansion rod is fixedly connected with a butting block; the tail end of each expansion rod is fixedly connected witha nesting block; a trapezoid block is nested with the nesting blocks; sliding chutes fitting in with the nesting blocks are formed in the trapezoid block; a screw rod is arranged in each sliding chute; and each screw rod penetrates through the corresponding nesting block and is in threaded connection with the corresponding nesting block. According to the bracket, by installing the three groups ofexpansion rods distributed triangularly, the butting blocks and the screw rods, the ectropion angle and the area of nostrils are adjusted to expand a visual angle and operating space, and observationand operation of medical workers are facilitated; by installing the headrest block, a horizontal adjustment mechanism, a vertical adjustment mechanism and an elastic strap, the head of a patient is conveniently fixed; and the expansion frame is fixed and adjusted, so that the stability and the adaptability of the bracket are improved.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a surgical bracket for nasal polypectomy. Background technique [0002] In the traditional nasal polypectomy, the operating doctor needs to perform polypectomy in the nasal cavity, and needs to extend the visible tube, ring cutting forceps, cutting forceps, etc. into the nasal cavity. There is no bracket in the traditional nasal polypectomy. During the process, the angle of the nostrils is fixed, which hinders the operation of the tubular instrument, and requires force to contact it, which affects the stability of the operation, and the operation space is small. Contents of the invention [0003] The object of the present invention is to provide a nasal polypectomy surgery bracket to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A stent...
