Detachable vertebral plate rongeur

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to a detachable vertebral plate rongeur. The detachable vertebral plate rongeur comprises a main body, a sliding rod and a movable handle, wherein the movable handle is connected with the main body and the sliding rod simultaneously; a pressing type lock catch structure located behind the movable handle and the sliding rod is arranged on the main body; the pressing type lock catch structure is provided with a first limiting part and a second limiting part; the pressing type lock catch structure has afirst state and a second state; when the pressing type lock catch structure is in the first state, the first limiting part is separated from the sliding rod, the second limiting part abuts against themovable handle and limits the rotating range of the movable handle, and the movable handle rotates to drive the sliding rod to move along a sliding rail; and when the pressing type lock catch structure is in the second state, the first limiting part is connected with the sliding rod, the second limiting part is connected with the movable handle, the sliding rod leaves the sliding rail, and the rear end of the sliding rod is connected with the movable handle and forms a fixed angle with the main body. The detachable vertebral plate rongeur is convenient to clean and disinfect and can be cleaned without being detached into spare parts, and the problem that components are prone to loss is solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a detachable lamina rongeur. Background technique [0002] Laminar rongeurs are mainly used in clinical operations, especially in neurosurgery, to bite and cut small bones and soft tissues. At present, the clinically used lamina rongeurs have the following problems: [0003] Most traditional lamina rongeurs cannot be disassembled and can only be cleaned as a whole. However, during the operation process, bone debris and tissues are often left in the gaps of the lamina rongeur, which is difficult to clean thoroughly, and long-term use is likely to cause serious consequences such as cross-infection; [0004] There are also some detachable lamina rongeurs on the market, but they can only be disassembled into parts for cleaning, and there are certain requirements for the placement position. When cleaning and sterilizing a bunch of surgical instruments, it takes a lot of...
