Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of endoscope sheath tubes, in particular to a novel endoscope sheath tube structure. Background Art
[0002] When diagnosing and treating lesions in a patient's body, an endoscope is usually used. In specific use, the insertion tube of the endoscope needs to be inserted into the patient's body, and the bending section of the insertion tube is controlled to bend so that the camera at the far end of the insertion tube can obtain image information of the target position.
[0003] When using an endoscope, due to various factors, such as problems with the instrument itself, the operator's proficiency, and the patient's own nausea and vomiting reactions that cause gastric and esophageal mucosal damage and bleeding, the endoscope body is inevitably contaminated with the patient's body fluids and blood. Many pathogens, such as: multiple hepatitis viruses, HIV, Helicobacter pylori, Staphylococcus, Pseudomonas aeruginosa, fungi, etc., can be transmitted through body fluids and blood.
[0004] Therefore, a disposable sleeve is needed to protect the endoscope during use. After use, only the endoscope head that may come into contact with body fluids needs to be cleaned. However, the existing sleeve tools are simply rubber tube heads that are connected to the endoscope during use, resulting in poor fixation with the endoscope, which may cause the endoscope to fall off when the endoscope insertion tube moves. Utility Model Content
[0005] 1. Problems to be solved
[0006] The technical problem to be solved by the utility model is that when the endoscope is in use, the existing sleeve structure is only fixed by sleeve connection through the contraction and tension of the tube body, which causes the tube body to slip off easily when in use.
[0007] (II) Technical solution
[0008] In order to solve the above technical problems, the technical solution provided by the utility model is: a new type of endoscope sheath tube structure, including a tube body and a joint, the tube body is connected to one end of the joint and the two are connected, a conical head is provided on the joint away from the end of the tube body, and the diameter of the conical head gradually decreases toward the tube body, and a plurality of groups of shrinkage rings are connected to the inner wall of the joint near the end of the conical head, and a plurality of deformation plates are evenly arranged in the joint near one end of the tube body.
[0009] As an improvement, the conical head is provided with a thin sheet metal layer inside, the outer layer of the conical head is a rubber layer covering the thin sheet metal layer, a wire loop is concavely provided on the outer side of the rubber layer, and a tightening wire is provided inside the wire loop.
[0010] As an improvement, a plurality of arc-shaped rings are provided on the outer side of the rubber layer along the circumferential direction of the wire ring.
[0011] As an improvement, a slot is provided on the joint near the deformation piece, and the deformation piece is connected in the slot.
[0012] As an improvement, the deformation piece is made of metal material and the cross section of the deformation piece is an arc shape that matches the shape of the joint, and the inner arc surface of the deformation piece is also provided with a convex block that convexly protrudes outward.
[0013] (III) Beneficial effects
[0014] The advantages of the utility model compared with the prior art are: in the present application, a variety of fastening structures are made for the joint, and the endoscope is clamped by the matching shrink ring, deformation sheet and conical head, thereby ensuring the protective effect during subsequent use.
