Portable electronic visual nasopharyngolaryngoscope

Abstract

The invention discloses a portable electronic visual nasopharyngolaryngoscope which comprises a display part, a handle component and an inserting part; the handle component is provided with a control part main body and a handle; a bendable part and an inserting part head provided with a camera sensing unit are arranged at the front end of the inserting part; a control part for controlling a nasopharyngolaryngoscope tube head to steer is arranged in the handle component; the control part comprises an upper support frame in the handle, a turntable and an inhaul cable, wherein the turntable is arranged on the upper support frame and positioned in the control part main body; the inhaul cable surrounds the turntable and is connected with the two sides of the bendable part; a guide rail component is arranged on the upper support frame; the inhaul cable pulled and controlled by the turntable is constrained by the guide rail component; the guide rail component comprises a traction limit block arranged on the upper support frame and positioned on the downstream side of the turntable; corner guide pipes for guiding the inhaul cable are symmetrically arranged in the traction limit block. The portable electronic visual nasopharyngolaryngoscope disclosed by the invention has the benefit that through effectively controlling and guiding the inhaul cable, the inhaul cable moves downwards in parallel after being constrained to surround the turntable, so that the inhaul cable is more flexible in the traction process, and the problems of wear, even breakage caused by scraping in the traction process of the inhaul cable are solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an electronic visualization endoscope that penetrates into a human body to observe, diagnose and treat diseased organs in the human body. Background technique [0002] With the advancement of medical device technology, endoscopes have become an essential medical device in hospitals. Nasopharyngoscopy is one of them. Nasopharyngoscopes generally include a handle and an insertion portion at the front of the handle. In order to extend into the inside of the patient's cavity to have a larger inspection range, the head of the insertion part is provided with a bendable part, and the bending is controlled by pulling a cable connected to the head end of the insertion part by a control swing arm on the handle. For example, the Chinese invention patent application whose publication number is CN102488490A discloses a rigid intubation endoscope with an adjustable front ...
