An endoscope working sheath for urological surgery

Abstract

The invention discloses an endoscope working sheath used in urological surgery, which comprises a hard working sheath, the right end of the hard working sheath is fixedly connected with the fixed chuck at the left end of the fixed joint, and the endoscope at the right end of the fixed joint An endoscope joint is installed on the hole, and an operating instrument joint is installed on the operation hole at the right end of the fixed joint. The left end of the hard working sheath is bonded with an elastic head, and the right end of the elastic head corresponds to the fixed joint endoscope hole, the operating instrument joint, and the water injection. The position of the hole is provided with an auxiliary endoscope hole, an auxiliary operating instrument joint, and an auxiliary water injection hole. The cooperation of the hard working sheath and the elastic head makes it easy to push the endoscope working sheath used in urological surgery. The hard working sheath and the elastic The head slides relative to the elastic mantle, and the elastic head drives the left end of the elastic mantle to fold inward through the rubber ring, so as to avoid the patient's urethral injury and reduce surgical complications.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscope working sheath for urological surgery. Background technique [0002] In flexible ureteroscopic surgery, the ureteroendoscope can enter the body through the urethra to observe the lesion and can cooperate with surgical instruments to perform visual surgery in the body. Clinical internal examination and visual surgical treatment require endoscopes with clear images to help doctors improve the accuracy of diagnosis. However, the existing endoscope working sheaths for flexible ureteroscopic surgery are flexible working sheaths. The human body is damaged during the operation, but it is difficult to move forward because the flexible working sheath encounters resistance; after the flexible working sheath is placed for a period of time, foreign matter deposits on the surface and become rough, and when it is pulled out, it usually causes urethral damage to the pat...

Clinical internal examination and visual surgical treatment require endoscopes with clear images to help doctors improve the accuracy of diagnosis. However, the existing endoscope working sheaths for flexible ureteroscopic surgery are flexible working sheaths. The human body is damaged during the operation, but it is difficult to move forward because the flexible working sheath encounters resistance; after the flexible working sheath is placed for a period of time, foreign matter deposits on the surface and become rough, and when it is pulled out, it usually causes urethral damage to the patient, causing post-operation urination. Road irritation symptoms and bleeding, some cases cause urethral stricture, etc.
