Abstract

The invention relates to a regulatable medical operating sheath, and relates to the field of medical instruments. The regulatable medical operating sheath mainly aims at solving the technical problemsthat in the prior art, the tube diameter of an operating sheath is adjusted through the expansion and contraction of an airbag, so that the operation is complex, and the cost is high. According to the technical scheme, the regulatable medical operating sheath comprises connecting mechanisms, a fixing structure and sheath walls; the sheath walls and the connecting mechanisms are sequentially staggered and connected in an end-to-end mode to form a tubular structure; each connecting mechanism includes a first connecting wall and a second connecting wall; the first connecting walls are rotatablyconnected with the second connecting walls and first sheath walls, and the second connecting walls are rotatably connected with second sheath walls; when the operating sheath is in a first state, thefirst connecting walls and the second connecting walls keep relatively open under the effect of the fixing structure to make the tubular structure in a circular tube shape; when the operating sheath is in a second state, the first connecting walls and the second connecting walls are closed relative to the interior of the tubular structure.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a medical body cavity tube inserter, more specifically, an adjustable medical operation sheath. 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as a guide, and then a sheath with a fixed lumen size is placed along the guide wire, and then the guide wire is withdrawn, and the channel The build is complete.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 guide wire, when the sheath is...
