Disposable endoscope sheath with surgical instrument angle adjustment device

Abstract

The invention provides a disposable endoscope sheath with a surgical instrument angle adjustment device. A lifting mechanism body composed of a first lifting component and a second lifting component in a movably-connected mode is installed at the front end of the disposable endoscope sheath and located between the disposable endoscope sheath and the head of a surgical instrument, a drawing wire penetrates through a first installation hole and a second installation hole to be inserted into a groove of a connecting mechanism, the drawing wire is connected with the connecting mechanism through a buckling connecting mechanism, then a drawing ring is screwed into a spiral hole of the connecting mechanism, and therefore rapid connection between the drawing wire and the drawing ring is achieved. After biopsy taking forceps are inserted into an instrument channel of the disposable endoscope sheath till the biopsy taking forceps are inserted in the required depth, the lifting mechanism body is drawn by the drawing ring to be contracted, and meanwhile the aim of adjusting the angle of the biopsy taking forceps is achieved through the head of the biopsy taking forceps along with retraction of the lifting mechanism body.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a disposable endoscope sheath with an angle adjustment device for surgical instruments. Background technique [0002] In the medical field, such as urology, when performing inspections or minimally invasive operations on relevant parts of the human body, not only endoscopes are often used, but some surgical instruments may also need to enter the human body at the same time to cooperate with the endoscope to complete the corresponding diagnosis or treatment. , therefore need a kind of mirror sheath that can hold endoscope and surgical instrument simultaneously. In addition, in the past, some endoscope accessories that helped endoscopes and instruments enter the human body were mostly made of stainless steel, which can be repeatedly sterilized and used in combination. , scissors and other surgical instruments, but also pre-loaded instrument manipulator in the mirror sheath. In ...
