Abstract

The invention provides a fixing device which comprises a locking buckle component, wherein the locking buckle component has a locking state and a release state and comprises an annular locking piece,a handle and a connecting piece, wherein the annular locking piece is provided with an axial opening; a pipe fitting to be fixed is sleeved with the annular locking piece; one end of the handle is pivoted on one side, located at the axial opening, of the locking piece; the other end of the handle is an operation end; one end of the connecting piece is pivoted on the other side, located at the axial opening, of the locking piece; the other end of the connecting piece is pivoted at a part between the two ends of the handle; when an acting force is applied to the operation end, the locking bucklecomponent is switched over between the locking state and the release state; the device is simple to assemble; an anti-drop casing is provided with a plurality of rows of barb bodies; loosening of a sheath clamp or falling out of an abdominal cavity can be avoided; the injuries to tissues around a minimally invasive incision of an abdominal wall are small; and excessively deep entry of the sheathclamp into a patient can be avoided by a disc body of the anti-drop casing.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a fixing device. Background technique [0002] In laparoscopic surgery, sheath card puncture is a commonly used surgical method, and the slender operating instruments enter the abdominal cavity through the dedicated channel established by the sheath card for surgery. In general abdominal surgery, due to long-term operation or frequent entry and exit of various instruments into and out of the sheath card, it is easy to cause loosening of the tissue around the abdominal minimal wound, resulting in instability of the sheath card or prolapse of the abdominal cavity, affecting the smooth progress of the operation and increasing the risk of surgery . In the prior art, the fixing method of the sheath card mostly adopts a threaded structure, and the threaded structure causes great damage to the wound or is inconvenient to operate.
