Rigid endoscope used for examination and matched with balloon-shaped sheath tube

Abstract

The invention belongs to the technical field of medical appliances and particularly discloses a rigid endoscope used for examination and matched with a balloon-shaped sheath tube. The rigid endoscope comprises a rigid endoscope main body and the sheath tube used for examination and detachably used with the rigid endoscope main body, wherein the rigid endoscope main body comprises a rigid working end part, a cold light source connector, a data connector or an ocular lens input end; the sheath tube used for examination comprises a sheath tube shaft; an inflatable balloon used for closing a front end opening is integrally arranged at the front end opening of the sheath tube shaft; the inflatable balloon is a transparent body; an air guide tube with a one-way valve is arranged in the sheath tube shaft; and a sheath tube bayonet matched with the rigid endoscope main body is arranged at the back end part of the sheath tube shaft. According to the endoscope, a diseased region can be fixed and expanded by utilizing the inflated highly transparent balloon and human natural orifice wrinkles can be effectively supported open, so that the view field of an examination position under the endoscope is clear and visual; and the filling of liquid or air does not need to be carried out during examination, so that the air or liquid residues or leakage is not caused and the risk of intraoperative or postoperative complications is lowered.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a core medical tool for minimally invasive surgical inspection, that is, an inspection endoscope with a balloon sheath. Background technique [0002] At present, endoscopes are widely used by doctors in diagnosing or treating diseases. Doctors can insert a rigid endoscope through the natural orifice of the human body, so as to observe the lesions of specific organs or tissues under the premise of non-invasive or minimally invasive . However, the natural orifice of the human body generally has folds, which will exert a certain pressure on the inserted endoscope, resulting in unclear vision under the endoscope, difficulty in the movement of the endoscope, and even damage to surrounding tissues. At present, the method of gas or liquid filling is generally used to expand the inner wall of the site to be inspected or the surrounding cavity, but gas or liquid filling can easily lead...
