Technical Field
The invention relates to the technical field of surgical tools, in particular to a safe and rapid bone extractor.
Background
The ilium bone extraction operation is to sterilize the bone extraction position after the local infiltration anesthesia is effective, usually select the anterior superior iliac spine, cut the skin and subcutaneous fat layer until the ilium periosteum, usually cut the bone with a bone knife hammer, after the bone block is cut off, the wound area of the patient is large, and time-consuming, usually about 20min, the bone extraction wound is sealed by bone wax, stop bleeding tightly, then wash and stitch the incision layer by layer, and the aseptic dressing is wrapped and fixed. The bone pieces taken by ilium are commonly used for the bone grafting treatment of the operation area of patients with bone nonunion, bone tumor, bone tuberculosis, bone defect, osteomyelitis and the like. Some patients also require multiple bone removal treatments. When the bone is stripped, the splashed bone fragments can generate secondary injury to the patient, the wound healing time is long, and the pain brought to the patient is great.
The prior bone surgery drill bit is generally sharp, and as disclosed in patent document CN202554036U, the bone surgery drill bit comprises a drill bit handle and a drill bit body, and the drill bit gradually and linearly tapers to form a cone shape in the direction of the drill bit at a position close to the drill bit and accounting for 1/5-1/3 of the length of the whole drill bit, wherein the area of the drill bit is 1/9-1/4 of the cross section area of the drill bit body. The drill bit gradually and linearly tapers to form a cone shape in the direction of the drill bit, so that the surface of the bone around the drill bit is prevented from being scratched by the enlarged drill bit, but soft tissues damaged by cortical bone are easily broken through in the bone drilling process, the bone cannot be safely taken, and the treatment of a patient is also not facilitated.
Therefore, how to provide a bone extractor with small trauma and safe bone extraction is a problem to be solved by the person skilled in the art.
