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

Abstract

The invention relates to the technical field of auxiliary instruments for the otorhinolaryngology department, in particular to a multi-angle direction-changing suction tube type curette for the otorhinolaryngology department. The multi-angle direction-changing suction tube type curette for the otorhinolaryngology department comprises a suction tube, wherein a threaded part is arranged outside the suction tube, and two groups of symmetrical strip-shaped openings are formed in the threaded part of the suction tube; a limiting rod is slidably connected to the suction tube at the strip-shaped openings, an L-shaped pull rod is fixedly connected to the middle of the side, located in the suction tube, of the limiting rod, a spring tube is connected to one end of the suction tube, and a bent part is connected to one end of the spring tube and comprises a bearing tube; and one end of the L-shaped pull rod penetrates through the spring tube to be bonded with the inner wall of the bearing tube, and an internal thread is arranged on the inner wall of one end of the bearing tube. The bearing tube and the curette are bent and adjusted to a certain degree, and the focus is treated conveniently; and the curette can be properly adjusted according to the specific requirements of a patient in the using process of the device, and the whole treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of otolaryngology auxiliary instruments, in particular to a multi-angle and direction-changing straw curette for otolaryngology. Background technique [0002] In the process of otolaryngology treatment, a curette is usually used to facilitate patients to scrape off polyps and blood stains in the throat and other lesions, and then cooperate with the suction device to absorb the dirt, which is convenient for subsequent treatment. However, because the ENT is not straight through, there is a certain angle of bending, and the existing devices usually require multiple devices to cooperate during use, the process is cumbersome, and it is easy to cause discomfort to the patient. Therefore, we propose a Disclosed is a multi-angle reversing straw curette for ENT. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a multi-angle reversing...
