Abstract

The invention discloses a diagnostic and treatment apparatus sheath for an endoscope, relates to the field of medical apparatus, and aims to solve the existing technical problem of complicated operation and higher cost caused by adjusting the pipe diameter of the operation sheath through the expansion and reduction of an air bag. The technical scheme includes that the diagnostic and treatment apparatus sheath for the endoscope comprises a connecting mechanism, a fixing structure and sheath walls; the sheaths and the connecting mechanism intersect successively, and the head and the tail are connected to form a tubular structure; the connecting mechanism comprises a first connecting wall and a second connecting wall; the first connecting wall is rotationally connected with the second connecting wall, the first connecting wall is rotationally connected with a first sheath wall, and the second connecting wall is rotationally connected with a second sheath wall; wherein the diagnostic and when treatment apparatus sheath for the endoscope is in the first status, the first connecting wall and the second connecting wall keep open oppositely under the action of the fixing structure, so thatthe tubular structure is of a circular tube shape; when the diagnostic and treatment apparatus sheath for the endoscope is in the second status, the first connecting wall and the second connecting wall are closed oppositely towards the inner portion of the tubular structure.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to a medical body cavity tube inserter, more specifically, an endoscope sheath for a diagnostic and therapeutic instrument. Background technique [0002] Endoscopic operation is widely used clinically, and has the advantages of less damage and faster postoperative recovery. Before the operation, it is often necessary to establish a large enough channel in advance with the help of an operating sheath, and then enter the body through the cavity inside the operating sheath for operation. [0003] At present, the commonly used channel establishment method is external expansion, that is, a thin guide wire is first inserted as a guide, and then a sheath with a fixed lumen size is placed along the guide wire, and then the guide wire is withdrawn, and the channel The build is complete. This method has the following disadvantages: first, because the sheath is wrapped around the g...
