Abstract

The invention relates to the technical field of medical instruments, and mainly aims to reduce the depth of a needle tube inserted into the body of a patient and improve the operation quality. The bone meal extractor comprises a needle tube, a needle core and a bone meal collecting device; one end of the needle tube is rotatably connected with a sucker, the interiors of the two are communicated toform a bone meal channel, and a chute is formed in the side wall of the needle tube; the needle core is sleeved with the needle tube, the needle core is sleeved with a pushing piece, the needle coreand the pushing piece are in threaded fit, the pushing piece is provided with a pushing part extending out of the sliding groove, and the pushing part is used for being driven to push the pushing piece along the sliding groove so that the needle core can rotate; a drill bit is arranged at one end of the needle core and used for penetrating out of the sucker through the bone meal channel, and a spiral chip groove used for being communicated with the bone meal channel is formed in the drill bit; and the bone meal collecting device is used for collecting bone meal from the bone meal channel. According to the technical scheme, extra injuries caused by unnecessary insertion in the prior art can be reduced, and the operation quality is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bone meal extractor for surgery. Background technique [0002] At present, allogeneic chemical synthetic materials such as silica gel, bone meal, and puffy body are used in cosmetic surgery for rhinoplasty and mandibular augmentation. These materials often produce foreign body rejection and cause physical discomfort to patients. The patient's own bone meal is used as filler for cosmetic surgery. Wherein, need to use bone meal extractor when extracting patient's bone meal. [0003] Such as figure 1 As shown, the patent with the notification number CN205379334 discloses a bone powder extractor, which includes a needle tube 1, a needle core 2 that can be inserted into the needle tube 1, an open groove 11 is provided on the side wall of the needle tube 1 front end, and a needle core 2 front end The side wall is provided with a plurality of conical protrusions 22 for ...
