Abstract

The invention provides a bone fetcher. The bone fetcher comprises a main cylinder body, a center rod and a cutter, wherein the main cylinder body is provided with a hollow pipe cavity; a part of the hollow pipe cavity close to the first end of the main cylinder body is used as an accommodating cavity for accommodating breeding bones; the center rod extends from the second end of the main cylinderbody to the hollow pipe cavity, and is arranged in the axial direction of the hollow pipe cavity in a sliding manner; the cutter comprises a propping push plate and a cutting edge structure, wherein the propping push plate is arranged at one end adjacent to the accommodating cavity, of the center rod; the cutting edge structure is arranged on the end surface of one side deviating from the center rod, of the propping push plate; the cutter is pushed by the center rod to enter the accommodating cavity; the cutting edge structure is used for cutting the breeding bones into a plurality of sclerotin slices; and the propping push plate is used for pushing the sclerotin pieces out of the accommodating cavity. Through the adoption of the bone fetcher disclosed by the invention, the problems that in the prior art, the bone fetcher is unreasonable in structure, single in function and poor in practicality are solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multi-functional drilling and grinding bone extractor. Background technique [0002] The bone extractor is used to pick up the seed bone so as to carry out the bone graft operation, but the bone extractor in the prior art has the problems of unreasonable structure, single function, and poor practicability; specifically, when the bone extractor completes the bone extraction operation , the bone seed in the hollow sleeve at one end of the bone extractor cannot be quickly removed, and the existing bone harvester cannot cut the bone seed, so medical personnel are required to cut the bone seed taken out of the hollow sleeve Using it after operation will increase the time of bone grafting operation and increase the difficulty of bone grafting operation; it not only affects the success rate of bone grafting operation, but also increases the pain of patients in bone graftin...
