Description

Cartilage shaping scissors

Technical Field

The utility model relates to the technical field of bone scissors, in particular to a cartilage shaping scissors.

Background

Cartilage (cartilage), i.e. cartilage tissue, is composed of chondrocytes and cellular interstitium, and the matrix in cartilage is in gel state and has greater toughness. Cartilage is a supportive-based connective tissue. The cartilage does not contain blood vessels and lymphatic vessels, nutrients permeate into cell interstitial substances from blood vessels in the perichondrium and then nourish bone cells, and cartilage scissors are needed to cut and shape the cartilage when the cartilage is subjected to operation cutting.

For example, the utility model with publication number CN216777155U discloses an otology cartilage shaping shear, wherein both an upper blade and a lower blade are provided with semicircular arc-shaped blades. This design does not influence cartilage shaping and tailors, and is convenient for cut out the back and take out cartilage, and accessible wherein a blade does not have the sword part and takes out cartilage, can not appear cartilage inlay card phenomenon, in order to be convenient for blade and shearing quick connect and dismantlement of handle of a knife, go up blade and lower blade back and all be equipped with the elastic column, it is equipped with the socket rather than the matching to go up head and lower head, elastic column compressible slide-in socket back bullet is opened fixedly, in order to block the rotation of blade in the operation, be equipped with on the socket and be used for the backstop elastic column rotatory backstop portion, backstop portion embeddable elastic column vacancy position realizes the backstop function.
