Hard intubation endoscope with adjustable front-end angle

Abstract

The invention relates to a hard intubation endoscope with an adjustable front-end angle. An eyepiece component is connected with a tip part sequentially through an operation part, a hard insertion part and an adjustable bent part; an image transmission element is a photoconductive fiber bundle and sequentially passes through the operation part, the hard insertion part and the adjustable bent part; an objective lens component is arranged in the tip part and is connected with the eyepiece component through the image transmission element; the operation part is matched with a light-emitting diode (LED) light source; a lighting optical fiber sequentially passes through the operation part, the hard insertion part, the adjustable bent part and the tip part; the operation part is provided with a rotating handle and comprises a steel cable; the steel cable passes through the hard insertion part and the adjustable bent part and is respectively connected with the rotating handle and the adjustable bent part, and can control the up-and-down bending angles of the adjustable bent part; and a pliers channel and a leak testing device are arranged. The hard intubation endoscope with the adjustable front-end angle has a unique design and a simple structure, is convenient to operate, has long service life, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to the technical field of endoscopes, in particular to a rigid intubation endoscope with an adjustable front end angle. Background technique [0002] At present, the fiberoptic intuboscopes used in most hospitals in China can be roughly divided into two types: fully flexible and fully rigid. The main difference between the two is the insertion part. The former uses a metal spiral tube wrapped with polyurethane and metal mesh cloth as the insertion tube, and connects dozens of stainless steel tubes in twos with rivets as a curved tube connected to the tip, and then wraps the curved tube tightly with a soft curved rubber to make the tip The bending angle of the first part can be adjusted manually; while the latter uses a stainless steel hard tube as the insertion part, and the tip part is directly connected to it, and the curved tube lacking the bending rubber wraps the t...

The former uses a metal spiral tube wrapped with polyurethane and metal mesh cloth as the insertion tube, and connects dozens of stainless steel tubes in twos with rivets as a curved tube connected to the tip, and then wraps the curved tube tightly with a soft curved rubber to make the tip The bending angle of the first part can be adjusted manually; while the latter uses a stainless steel hard tube as the insertion part, and the tip part is directly connected to it, and there is no curved tube wrapped with bending rubber to transition from it, so that the bending angle of the tip part cannot be adjusted

Their advantages and disadvantages are very obvious: From the perspective of the difficulty of inserting into the patient's body, the all-rigid intuboscope is much easier than the all-flexible intuboscope; but when encountering patients with special morphological signs At this time, the full rigid intuboscope can not be adjusted because of the bending angle of the tip, so that it is not suitable to realize the quick and accurate patrol positioning, while the full flexible intuboscope can adjust the front angle but it is not easy to insert
