Improved angle adjusting mechanism for endoscope

Abstract

The invention provides an improved angle adjusting mechanism for an endoscope. The improved angle adjusting mechanism for the endoscope comprises an angle adjusting steel wire, a center shaft, a steel wire rope turning wheel and a locking mechanism. One end of the angle adjusting steel wire is connected with a soft sheath of the endoscope, the other end of the angle adjusting steel wire is wound on the steel wire rope turning wheel, the steel wire rope turning wheel is arranged on the center shaft in a sleeved mode and fixedly connected with the center shaft, the two ends of the center shaft are located in locating holes in a handle of the endoscope, and the center shaft is fixedly connected with an angle adjusting handle. The locking mechanism comprises a fixed friction plate which is arranged on the center shaft in a sleeved mode and fixedly connected with the center shaft and an axial pressing mechanism which is movably arranged on the center shaft in a sleeved mode and can press the steel wire rope turning wheel onto the fixed friction plate. The steel wire rope turning wheel is arranged between the fixed friction plate and the axial pressing mechanism. The improved angle adjusting mechanism for the endoscope can meet the requirement of free positioning in the operation process, prevent misoperation from harming a patient, achieve conformance of the bending angle of the angle adjusting handle and the bending angle of the soft sheath, lead the soft sheath to be locked automatically at an operation position, and meet the requirement that an operator can operate the endoscope by one hand.

Description

technical field [0001] The invention relates to a medical device, in particular to an improved angle adjustment mechanism for an endoscope. Background technique [0002] In clinical medicine, endoscopic treatment is currently the most commonly used method of diagnosis and treatment. This method is the so-called minimally invasive diagnosis and treatment method, which causes less damage to patients. Traditional flexible endoscopic treatment requires the cooperation of multiple physicians, and the diagnosis and treatment effect of flexible endoscope is highly dependent on the skills and experience of physicians. To avoid repeated angle adjustment and positioning in the patient's body, there are higher requirements for the stability and sensitivity of the flexible endoscope device. High safety and high efficiency of endoscopic devices are an urgent need to meet the requirements of clinical diagnosis and treatment. Due to operation errors caused by long-term operation fatigue ...

AI Technical Summary

Problems solved by technology

Due to operation errors caused by long-term operation fatigue of the operator, it is likely that when the soft endoscope intervenes in the human body, a large extrusion force will occur between the soft endoscope lens and the human tissue. When the extrusion force exceeds a certain When the threshold is exceeded, it will lead to soft tissue damage, which may lead to medical accidents such as perforation of human tissue

At present, there are roughly two types of flexible endoscopes, one is to use an angle slider to limit the position, and the other is to use a traction device with a locking mechanism. These two types of endoscopes have complex structures and require high manufacturing precision. The assembly of various parts requires high correlation and interaction, and a high degree of dependence on other devices of the endoscope. The operation requires the coordination and adjustment of the endoscope as a whole, and the use efficiency of the endoscope is low.
