Bidirectional bend-adjusting endoscope

Abstract

The invention discloses a bidirectional bend-adjusting endoscope, which comprises a front end part, an adjustable bending part, a hard insert part, an operation handle, and a light guide beam, an eyepiece component and an operation channel which can orderly penetrate through the operation handle, the hard inserting part, the adjustable bending part and the front end part. The adjustable bending part comprises several joints sleeved on the elastic supporting body and pull ropes penetrated at the inner part of the joint; there are two groups of pull ropes, the joint bending spaces closing to both sides between the joints can pass through the inner part of the joint; the front end of the pull ropes and the end joints fixedly connected with the front end part are fixed to form a stress anchorpoint; the tail end is fixedly connected with a reciprocating operation mechanism on the operation handle; the adjustable bending part can be controlled to vertically bend through the operation handle. The endoscope pipe body has straight state and bending state; the pipe body in straight state can insert to the patient body conveniently, the front end angle is adjustable when the pipe body is under the bending state; through the eyepiece component and the light guide beam, the touring location can be realized exactly, and the observing blind zone is reduced.

Description

technical field [0001] The invention belongs to the field of minimally invasive medical devices, and in particular relates to a two-way bending-adjustable endoscope. Background technique [0002] Clinically, minimally invasive biliary endoscopy is widely used as a key instrument for gallbladder stone removal due to its advantages of high removal rate, small trauma, quick recovery, and low recurrence rate. The biggest advantage of endoscopy is that stone removal is more thorough and clean, which can significantly reduce the rate of residual stones after surgery and increase the success rate of residual stone removal, thereby reducing the number of stone removal operations, saving medical expenses and relieving pain for patients. In addition, it is more convenient to use choledochoscope to biopsy the extrahepatic and extrahepatic bile duct vegetations and new organisms for qualitative diagnosis.

Problems solved by technology

[0003] However, at present, the fiber choledochoscopes used in major hospitals in China can be divided into rigid choledochoscopes and soft choledochoscopes. Among them, the rigid choledochoscope is easy to insert into the patient's body, but it cannot turn itself, and it is difficult to adapt to the changing shape and signs of the patient's internal pipeline. , while the soft choledochoscope itself is soft, and the angle of the head end can be bent and adjusted to adapt to various morphological characteristics of the patient's internal pipeline, but the soft mirror body is not easy to insert into the patient's body

[0004] Since the biliary endoscope cannot be both soft and hard

Therefore, at present, many medical device companies have developed some adjustable endoscope products for this technical problem. For example, patent documents such as CN102488490A, CN107088045A, and CN205514712U have proposed technical solutions to the above-mentioned problems, but the above-mentioned solutions The structure is relatively complicated, and it is not easy to adjust the bending of the endoscope during the actual operation process. The adjustable bending part and operating handle of the bending structure have no actual changes from imported products.
