Abstract

The invention provides a costal cartilage slicer. The costal cartilage slicer comprises a base, a knife holder, a fixing structure, a chuck structure, a knife rest and a stop block, wherein the kniferest is used for detachably mounting a blade; the knife holder is arranged on the base; one end of the knife rest is rotationally connected to the knife holder, so that the blade is driven to cut a costal cartilage block through rotation of the knife rest; the stop block is arranged on the lower side of the knife rest; the chuck structure can move in a reference direction relative to the fixing structure; the fixing structure is arranged on a first side of the chuck structure in the reference direction; the stop block is located on a second side of the chuck structure in the reference direction; and the costal cartilage block to be sliced can be tightly clamped between the stop block and the chuck structure. The thickness of a costal cartilage slice sliced by the costal cartilage slicer can be uniform and consistent.

Description

technical field [0001] The invention relates to surgical instruments, in particular to a costal cartilage slicer. Background technique [0002] The main operation method of rhinoplasty is the combination of Yamane nasal dorsum prosthesis and costal cartilage nose tip, collectively referred to as costal cartilage nose surgery. [0003] In the existing related technologies, the massive costal cartilage is usually cut into three to six pieces of costal cartilage by manual cutting by relevant personnel. The top, bottom, left, and right thickness of the slices are completely uniform, and it is impossible to make two or more costal cartilage slices have the same thickness. Uneven and inconsistency in thickness will lead to unstable support of the left and right sides of the nose tip bracket, which may easily lead to postoperative problems such as nose tilt. Contents of the invention [0004] The invention provides a costal cartilage slicer to solve the problem that the thicknes...
