Problems solved by technology
[0008] However, this scalpel is difficult to use in conjunction with the ultrasonic surgical scalpel system
In addition, if this scalpel is used for bone cutting operation, a lot of bone residue will be generated, which will affect the operation
In addition, this kind of scalpel cannot perform operations such as drilling holes in bones.

The invention discloses an ultrasonic surgery scalpel system, and belongs to the medical apparatus technical field; the system comprises an ultrasonic energy transducer, cutters and a protection sheath; the cutter is detachably connected with the ultrasonic energy transducer; the protection sheath is provided with a liquid injection tube, and wraps the cutter periphery; a connecting receive space is arranged between the protection sheath and the cutter; the liquid injection tube is connected with the receive space; a plurality of types of cutters are provided, and the cutter can be selected from various cutters according to different operational demands; in application, the perfusate is injected to the receive space between the protection sheath and the cutter through the liquid injection tube, and flows onto the cutter head so as to clean a wound, thus ensuring the wound to be clean, providing a clear operation visual field, and improving the operation quality ; in addition, the perfusate can cool down the cutter head, so the cutter head temperature can be lowered without burning body tissues; in addition, a plurality of selectable cutters are provided, and different cutters can be selected according to different operational needs, thus providing strong applicability.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ultrasonic scalpel system. Background technique [0002] In orthopedic surgery, ultrasonic osteotome is often used for cutting, grinding, planing, scraping or arbitrary shaping of bone. When doctors perform this kind of operation, they often control the range of motion of the ultrasonic osteotome according to their own ability, such as the depth of cutting, etc., which is highly subjective, especially for orthopedic surgery. The preset depth of the cutting knife is often blocked unexpectedly, which expands the wound surface and is not conducive to the treatment of patients. In order to solve the above problem: [0003] The Chinese invention patent with the application publication number of CN 102462528 A discloses an ultrasonic osteotome and its usage method. See attached figure 1 , which includes an ultrasonic transducer 01, a cutter head 03 and a protective c...
