A hand-held electric bone drill

Abstract

The invention discloses a hand-held electric bone drill. The bone drill includes a bone drill body, a drill bit and a cylinder having an opening on one end; the other end of the cylinder is connectedto a hinge wheel; the hinge wheel is movably in hinged joint with a first bracket; the other end of the first bracket is in hinged joint with a second bracket; the other end of the second bracket is in hinged joint with a third bracket; the outer side of the third bracket is connected to an arc sheet; the bone drill body is inserted in the cylinder; the inside of the cylinder is fixedly connectedto a slide rail; one side of the bone drill body is connected to a slide block; the slide block is slidingly sleeved by the slide rail; a second tooth part is fixed on the other side of the bone drillbody; the cylindrical surface of the cylinder is provided with a square gap, and the square gap is connected to a supporting shaft; the supporting shaft is sleeved by a rotating wheel; a first toothpart is fixed on the other side of the rotating wheel; the bone drill body is provided with a row of blind holes; and an inserted bar is movably inserted in the cylinder, and the inserted bar can choose one blind hole to inster. The bone drill can improve the insufficient in the prior art, and has characteristics of easy holing and convenient operation.

Description

technical field [0001] The invention relates to a medical device, in particular to a hand-held electric bone drill. Background technique [0002] Bone drill is a kind of medical instrument commonly used in orthopedic surgery, and the method that generally adopts now is that the doctor uses hand-operated bone drill. Chinese utility model patent CN 203662843 U discloses a miniature rechargeable electric bone drill. The bone drill with this structure drives the high-speed rotation of the main shaft through the operation of the high-speed micro-motor, and drives the synchronous high-speed concentric rotation of the drill bit through the transmission of the concentric output connecting rod of the motor and the driven shaft, thereby realizing the drilling function. The structure of the bone drill is inconvenient for personnel to operate. When the medical personnel operate on the patient, they are very tired when holding the bone drill and cannot control the depth of the drill bit...

Problems solved by technology

The bone drill with this structure drives the high-speed rotation of the main shaft through the operation of the high-speed micro-motor, and drives the synchronous high-speed concentric rotation of the drill bit through the transmission of the concentric output connecting rod of the motor and the driven shaft, thereby realizing the drilling function. The structure of the bone drill is inconvenient for personnel to operate. When the medical personnel operate on the patient, they are very tired when holding the bone drill and cannot control the depth of the drill bit, which adds great difficulty to the medical personnel and limits their scope of application
