Novel tissue cutting double-headed scissors

Abstract

The invention discloses a pair of novel tissue cutting double-headed scissors. The novel tissue cutting double-headed scissors comprise a first scissor head and a second scissor head; the first scissor head comprises a first upper scissor back, a first upper blade arranged on the inner side of the first upper scissor back, a first lower scissor back and a first lower blade arranged on the inner side of the first lower scissor back; the second scissor head comprises a second upper scissor back, a second upper blade arranged on the inner side of the second upper scissor back, a second lower scissor back and a second lower blade arranged on the inner side of the second lower scissor back; the first upper scissor back and the second upper scissor back are connected through a first connecting part; the first lower scissor back and the second lower scissor back are connected through a second connecting part; and the first connecting part and the second connecting part are connected in an opening and closing manner. Separating, fixing and shearing can be achieved at the same time, it is guaranteed that materials are qualified, surrounding muscles / blood vessels / nerves are not damaged, and damage to target materials is reduced. Different types of scissor heads can be replaced according to different target materials and use scenes, so that the purpose of taking materials is achieved; and the structure is simple and use is convenient.

Description

technical field [0001] The invention relates to the field of medical equipment and experimental equipment, in particular to a novel tissue cutting double-head scissors. Background technique [0002] In medical operations, animal experiments, and plant experiments, the sampling of target materials (target materials) is often involved, and a part of the tissue material (sampling tissue) taken out can be used for subsequent analysis or experiments. Material collection can be used for material analysis, which requires exploring changes while ensuring minimal or no impact on the subsequent survival of humans, animals and plants. The analysis of the experimental target material usually requires a certain volume and quality of the material, so that the subsequent analysis data or research on the material can be displayed more comprehensively and with higher credibility. The process of collecting materials includes two processes of fixing and intercepting the target material. Unde...

Problems solved by technology

[0006] Although there are many types of tissue scissors currently used to obtain materials, none of them can cut off the two ends of the tissue while fixing the tissue. The tip of some instruments, such as surgical blades, is very likely to touch blood vessels, nerves and important organs when operating in deep tissues of the human body or animals and plants. Internal organs, etc., causing additional damage and bleeding. For example, in muscle biopsy, the blade used to amputate muscles, because the tip of the knife is very sharp, the tip is very easy to scratch the muscles or blood vessels in the non-operative area, which will not only cause Unnecessary damage will also affect the quality of the material
