(II) technical scheme

A scalpel for carving nasal cartilage is composed of two blades, one sharp blade for cutting cartilage and another blunt blade for assisting the sharp blade to cut cartilage and prosthesis material, and is composed of a blade connected to handle, a blade connector sleeved at the joint of handle, a fixed blade clamped at front end of blade connector, two blades connected by screws, a spring sleeved outside the screw at the joint of two blades, a small regulating screw at the front position of external surface of blade connector, a screw slot at rear end of blade, a blade connector with slightly narrow width, a telescopic function, a blade sliding groove at front end of handle, a blade sliding groove at front end of blade, and a spring for fixing the blades, can compensate the looseness of the blades without stress points

Preferably, the handle of a knife is including anti-skidding recess, blade connector, blade spout, the handle of a knife indicates that the end design has anti-skidding recess of holding, the handle of a knife front end is provided with the blade connector, blade spout is provided with in the blade connector.

Preferably, blade connectors are arranged on two sides of the blade connector, and a pair of blade connectors is arranged.

Preferably, the interior of the knife body connector is designed to be hollow, the exterior of the knife body connector is additionally provided with blade adjusting screws, and the blade adjusting screws are arranged in a pair.

Preferably, the blade fixing screws are used for fixing the surgical blades, and the surgical blades are arranged in a pair.

Preferably, the surgical blade is designed as a blunt blade and a sharp blade.

Preferably, a concave sliding groove is arranged in the middle of the surgical blade.

(III) advantageous effects

The utility model provides a scalpel for carving nasal cartilage. The method has the following beneficial effects:

(1) the scalpel for carving the nasal cartilage is characterized in that a sliding groove is formed in the inner part of the scalpel body connecting part, so that the scalpel body can move left and right.

(2) This carving nasal cartilage's scalpel secondly adopts the screw cup joint the spring outward, can adjust the wide and narrow interval between the scalpel blade when the operation demand to make its atress fixed through the spring, the blade passes through the screw fixation with the blade connector, and design spill spout in the middle of the blade can compensate when requiring that double blade improves or reduces the height interval, and adjustable screw carries out telescopic fixed.

(3) The scalpel for carving the nasal cartilage is finally designed to accord with the field operation environment, so that the flexibility of the scalpel is increased, the installation process is simpler, and the operation time is accelerated.
