Self-locking angle adjustment mechanism for endoscope

Abstract

A self-locking angle adjustment mechanism for an endoscope, comprising an endoscope angle adjustment steel wire (5), a rotating handle (2), an endoscope handle (3) and a The self-locking rotating device is provided with an outer conical surface coaxial with the rotating shaft on the outer surface of the rotating shaft (7), and a matching cone is sleeved outside the outer conical surface, and the inner wall of the cone is an inner conical surface, so The inner conical surface corresponds to the outer conical surface; the axial direction of the rotating shaft (7) or the cone is provided to allow the rotating shaft (7) to move towards the direction of the cone or the cone to move towards the direction of the shaft (7), and Force the inner conical surface and the outer conical surface to closely fit each other to achieve self-locking spring (14); the inner end of the endoscope angle adjustment steel wire (5) is fixed on the rotating shaft (7), and the rotating The handle (2) links to each other with the rotating shaft (7). The soft sheath (4) can be infinitely locked at any position, which meets the requirement of free positioning of the endoscope during the operation, reduces labor intensity during the operation, and prevents injury to the patient due to misoperation.

Description

technical field [0001] The invention relates to a medical device, in particular to a self-locking angle adjustment mechanism for an endoscope. Background technique [0002] In clinical medicine, endoscopic treatment is currently the most commonly used minimally invasive diagnosis and treatment method, which causes less damage to patients. At present, flexible endoscopes generally control their bending and steering through scissor handles and steering wires. The operation accuracy is not high, and the control of the angle is not accurate enough. During the operation, the angle adjustment device is used repeatedly with the operation of the medical staff. The angle of the steel wire will be more or less deviated, so that the accuracy of the operation is not high, and the repeated use of the steering wire will cause the steel wire to twist and bend inside the endoscope, and the angle adjustment sensitivity of the endoscope is low. There is also a push-pull handle. Their common...

Problems solved by technology

Their common feature is that they can achieve the purpose of turning the front end of the flexible endoscope, but they cannot be positioned and locked in real time. Doctors need to maintain a certain holding posture for a long time during the operation.

The operation process will consume a lot of physical strength of the doctors, and this kind of operation will increase their burden

If a negligence changes the holding posture of the hand, the angle of turning of the front end will change. Such a small change may bring great hidden dangers to the safety of the operation.
