Multi-angle direction-changing suction tube type curette for otolaryngology department

Abstract

The invention provides a multi-angle direction-changing suction tube type curette for the otorhinolaryngology department, relates to the technical field of medical instruments, and aims to solve the problem that a suction tube is easy to fold due to multi-directional movement of an existing suction tube type curette in the using process. The multi-angle direction-changing suction tube type curette comprises a curette body, an adjusting structure, a cleaning piece and a steering mechanism, wherein an anti-skid pad is mounted on the outer side of the curette body, and the adjusting structure is mounted on the outer side of the curette body; a rotating groove in the adjusting structure is formed in the outer side of the curette body, and a transverse plate in the adjusting structure is mounted on the outer side of the transverse rod in a sliding mode; the cleaning piece is mounted at the side end of the curette body, and a left scraping plate and a right scraping plate in the cleaning piece are rotationally mounted in the inner groove; and the steering mechanism is mounted on the side surface of the cleaning piece, and a left pipe in the steering mechanism is mounted on the side surface of a baffle. A suction tube pulls a right tube to move on the side surface of a left tube, so that a sliding plate moves in a sliding groove through a spring, folding of the suction tube is reduced, and circulation of the suction tube is kept.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a multi-angle reversing suction pipe curette used in otolaryngology. Background technique [0002] Otolaryngology is the surgical discipline that diagnoses and treats the ear, nose, pharynx, larynx, and its related head and neck areas. Rhinolaryngology surgical instruments are tools used in ENT surgical procedures. Curettes in nasal and throat surgical instruments are used in During the operation, some separated tissues and polyps are cleaned up, and it plays a very good role in cleaning up some fine meat tissues. [0003] For example, the application number: CN202010010112.0 relates to a multi-angle reversible straw-type curette for otolaryngology. A suction needle, a second suction needle and a rubber tube connecting the first suction needle and the second suction needle, the second suction needle is wrapped with a handle cover, and the end of the secon...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a multi-angle reversing straw curette for ENT, to solve the problem that the medical staff hold too many curettes during the operation of the existing straw curette. Azimuth movement will easily cause the part where the suction tube is connected to be folded, which will affect the suction of the separated tissue generated during the operation, and the angle of the curette is mostly fixed. For the separated tissue that needs to be cleaned at different parts, different curettes need to be replaced. The operation is cumbersome and the work efficiency is low
