Novel sampling knife handle

Abstract

The invention provides a novel sampling knife handle. The novel sampling knife handle comprises a knife handle body, knife clamps and knife blades, wherein the knife handle body is connected with the knife clamps in a split mode through connecting pieces, and the knife blades are inserted into the knife clamps in an embedding mode. Due to the fact that the knife handle body and the knife clamps are of a split structure, the knife clamps can be replaced even when damaged, the knife handle body can continue to be used, the usage rate of materials is largely improved, and the practicability of the novel sampling knife handle used for sampling medical pathological tissue is improved. The top side opposite to the position, where the knife blades are inserted in an embedding mode, of the knife clamps is further provided with a baffle, the baffle and the knife clamps are integrally formed, the knife blades will not be clamped between the baffle and the knife clamps even when too much effort is exerted, and the practicability of the novel sampling knife handle is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a split-type material-taking knife handle. Background technique [0002] The tool handle for material extraction is usually a tool used for pathological observation of hospital pathological tissues, such as tumor tissue. One-piece design, once the tool holder is damaged or broken, the entire tool holder needs to be replaced, which is wasteful. In addition, there are the following defects: 1. The blade of the traditional knife handle is too long relative to the knife holder, the blade is easily stuck in the pathological tissue, or the tail of the blade is easy to lift; 2. The knife holder 01 has a built-in split baffle 02, and the blade 03 When slicing too hard, the top is easily stuck between the split baffle 02 and the knife holder 01 (see figure 1 ); 3. The material of the traditional knife holder is thin and easy to deform; 4. The handle of the knife is made of wood or ord...

[0002] The tool handle for material extraction is usually a tool used for pathological observation of hospital pathological tissues, such as tumor tissue. One-piece design, once the tool holder is damaged or broken, the entire tool holder needs to be replaced, which is wasteful

In addition, there are the following defects: 1. The blade of the traditional knife handle is too long relative to the knife holder, the blade is easily stuck in the pathological tissue, or the tail of the blade is easy to lift; 2. The knife holder 01 has a built-in split baffle 02, and the blade 03 When slicing too hard, the top is easily stuck between the split baffle 02 and the knife holder 01 (see figure 1 ); 3. The material of the traditional knife holder is thin and easy to deform; 4. The handle of the knife is made of wood or ordinary plastic, which is easy to be damaged or corroded by formalin and other reagents and shorten the service life
