Medical endoscope control mechanism

Abstract

The invention belongs to the technical field of endoscopes, and particularly relates to a medical endoscope control mechanism. The medical endoscope control mechanism comprises a first hand wheel assembly, a second hand wheel assembly, a winding assembly, a first locking component and a second locking component; the winding assembly comprises a first control wheel, a second control wheel and a wire bunching shell, and a control cable of an endoscope penetrates through the wire bunching groove, and is connected with an inserting component of the endoscope; the first hand wheel assembly comprises a first linkage rod and a first hand wheel, one end of the first linkage rod is fixedly connected with the first hand wheel, and the other end of the first linkage rod is in driving connection with the first control wheel; the second hand wheel assembly comprises a second linkage rod and a second hand wheel, the second linkage rod penetrates through the first hand wheel, the first linkage rod and the first control wheel, one end of the second linkage rod is fixedly connected with the second hand wheel, and the other end of the second linkage rod is in driving connection with the second control wheel. The medical endoscope control mechanism has the advantages of being simple in structure, firm in locking, and not prone to locking failure.

Description

technical field [0001] The invention belongs to the technical field of endoscopes, in particular to a control mechanism for medical endoscopes. Background technique [0002] An endoscope is a commonly used medical device, including a control end and an insertion part. The insertion part includes a bending component. The control end is provided with a control mechanism, and the bending component is controlled by a control cable. The pores formed enter the body. There are many internal components in the insertion part, it is difficult to thoroughly disinfect, the maintenance cost is high, and repeated use is easy to cause cross infection. Most of the existing medical endoscopes use disposable endoscopic insertion parts. The control end of the endoscope is controlled by The cable controls the directional bending of the insertion portion and guides the working end into the body. [0003] In the prior art, the control mechanism of the endoscope includes a housing, a hand wheel ...

Problems solved by technology

There are many internal components in the insertion part, it is difficult to thoroughly disinfect, the maintenance cost is high, and repeated use is easy to cause cross infection. Most of the existing medical endoscopes use disposable endoscopic insertion parts. The control end of the endoscope is controlled by The cable controls the directional bending of the insertion part and guides the working end into the body

[0003] In the prior art, the control mechanism of the endoscope includes a housing, a hand wheel assembly, and a locking mechanism. The structure of the existing control cable control mechanism is complex, and the control cable is prone to slipping, causing control failure and making the bending direction control inaccurate. precise
