Description

scalpel blade

technical field

The utility model belongs to the field of medical instruments, in particular to a surgical blade suitable for paronychia surgery.

Background technique

Except for the free edge of the nail, the other three sides are connected with the skin folds, and the connection part forms a groove, called the nail groove. Some people tend to form paronychia because the nails on both sides will directly embed into the skin when they grow forward. When paronychia is severe, paronychia surgery is required, in which part of the nail piece that is easily embedded in the skin on one or both sides is completely cut and removed from the nail root to the nail plate, and then destroyed by peeling off the nail bed here The nail bed here, so that the deck no longer grows here. The head of the existing paronychia scalpel is a vertical sheet structure. During the operation, the scalpel needs to be tilted at a certain angle to remove the nail bed. First, because the operating space is limited, the tilt angle cannot be too large. Secondly, even if it is tilted, the operation is not very convenient. Generally speaking, it is laborious and time-consuming to destroy the nail bed. Moreover, for some serious cases where the nail bed is connected to the phalanx on the thumb, it is more inconvenient to completely remove the nail root and the nail bed.
