Problems solved by technology

Due to the setting of the opening of the storage chamber, when using this improved sampling knife for sampling, the tissue cannot be cut directly. It is necessary to cut the tissue into an area consistent with the size of the opening of the storage chamber before cutting, which lengthens the time for tissue preparation and processing. working hours, inefficiency

Embodiment

[0033] Such as Figure 1-5 As shown in the drawing, it is a pathological knife disclosed in the present invention, comprising a first knife handle 1 and a cross-cutting knife 2, the first knife handle 1 is stepped, and the bottom of the first knife handle 1 is opened for the cross-cutting knife 2 to slide. The first sliding groove 11 is shifted, and the first sliding groove 11 runs through the first knife handle 1 horizontally. One end of the first knife handle 1 is provided with a rectangular slicing groove 12, and the slicing groove 12 vertically runs through the first knife handle 1. A vertical cutter 13 is fixedly connected around the bottom of the slicing groove 12, and the end of the first handle 1 away from the slicing groove 12 is provided with a second sliding groove 14, the second sliding groove 14 is vertically perpendicular to the first handle 1 and In communication with the first sliding groove 11 , one end of the cross-cutting knife 2 is fixedly connected with a ...

specific Embodiment approach

[0040] When performing pathological material collection, the cross-cutting knife 2 is pushed away from the slicing groove 12 to expose the slicing groove 12, the engaging block 32 engages the cross-cutting knife 2, the vertical cutting knife 13 sinks into the tissue, and is adjusted to the required position. The thickness of the material is obtained, and the clamping block 32 is rotated, and the cross-cutting knife 2 moves toward the slicing groove 12 under the action of the spring 4, and cuts off what needs to be cut.

Abstract

The invention relates to a sampling knife for the pathology department, and belongs to the technical field of medical auxiliary equipment. The sampling knife comprises a first handle and a transversecutter; the first knife handle is step-shaped, a first sliding groove for sliding the transverse cutter is formed in the bottom of the first knife handle; the first sliding groove horizontally penetrates through the first knife handle; a rectangular slicing groove is formed in one end of the first knife handle; the slicing groove vertically penetrates through the first knife handle, a vertical cutter is fixedly connected to the bottom of the slicing groove, a second sliding groove is formed in the end, away from the slicing groove, of the first knife handle, the second sliding groove is vertically perpendicular to the first knife handle and communicates with the first sliding groove, and a push block is fixedly connected to one end of the transverse cutter and slides along the inner wall of the second sliding groove; when pathological sampling is carried out, the transverse cutter is pushed in the direction away from the slicing groove to expose the slicing groove and enable the vertical cutter to sink into tissue, the required sampling thickness is adjusted, the transverse cutter is pushed in the direction of the slicing groove to cut off the tissue needing to be cut off, the tissue does not need to be treated in advance during sampling, and the sampling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a cutting knife for pathology. Background technique [0002] Pathological examination mainly carries out cadaveric pathological examination and surgical pathological examination in clinical aspects. The purpose of surgical pathological examination is to clarify the diagnosis and verify the preoperative diagnosis and improve the level of clinical diagnosis. The second is to determine the next treatment plan after the diagnosis is confirmed. And estimate the prognosis, and then improve the level of clinical treatment. [0003] The existing material-taking knife requires the medical staff to fix the tissue with one hand while taking the material with the knife in the other hand. This operation method is easy to injure the fingers of the medical staff, and the cut tissue is easy to fall during the removal process. Trouble in the extraction process. Aiming at the...
