Problems solved by technology

However, the shape of the blade of the ring knife is complex, and its cross-section can be circular arc, elliptical arc or any closed shape including circular arc and elliptical arc, etc., which is not easy to clamp and locate.
[0004] In the related ring knife sharpness test device, only the knife tube of the whole ring knife can be clamped, so the test of the sharpness of the ring knife can only test the overall sharpness of the ring knife edge, and it cannot solve the local blade of the ring knife. Due to the clamping problem, it is impossible to test the sharpness of the local edge of the ring knife

Abstract

The invention provides a blade clamping device for cutting edge sharpness testing. The blade clamping device can solve the problem of local blade clamping of an annular cutter. The device comprises aconnecting and bearing mechanism, a guide mechanism and a pressing mechanism, wherein the connecting and bearing mechanism is used for connecting sharpness testing equipment, a blade accommodating groove is formed in the connecting and bearing mechanism, and a blade accommodating space for accommodating a blade to be tested can be formed between the blade accommodating groove and the pressing mechanism; the guide mechanism is connected to the connecting and bearing mechanism; the pressing mechanism is arranged on the guide mechanism and can move relative to the connecting and bearing mechanismunder the guide action of the guide mechanism so as to adjust the size of the blade accommodating space and press the blade to be tested; and the blade to be tested is a local blade which is sectioned from an annular blade.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blade clamping device for testing the sharpness of blades. Background technique [0002] The sharpness of the blade is one of the important reference factors to evaluate the quality of the knife. For some occasions, such as surgical scenes, the sharpness of the blade will greatly affect the quality of the operation. For example, the vacuum rotary cutting system uses a ring knife. The vacuum rotary cutting system is currently one of the most effective methods for breast biopsy surgery. It is necessary to repeatedly cut suspicious breast lesions to obtain enough breast histological specimens for breast biopsy. Early detection and diagnosis of cancer, and minimally invasive resection of benign breast tumors. Due to the dense structure and even calcification of the lesion tissue, the hardness of such lesion tissue is high, which requires the cutting edge of the rotary ...
