Abstract

The invention discloses an electric bone drill which comprises a body, a drill chuck, a fixing module, a limiting module, a quick release mechanism and a gear mechanism, a power source and an output shaft connected with the power source are arranged in the body, the drill chuck is rotationally connected to the body and detachably connected with the output shaft, and the quick release mechanism enables the drill chuck to be quickly mounted on the body. The limiting module is arranged on the peripheral side of the drill chuck and limits rotation of the drill chuck, the fixing module is arranged between the body and the limiting module and used for fixedly connecting the limiting module and the body, and the gear mechanism is arranged on the peripheral side of the fixing module and restrains the limiting function of the limiting module. The quick release mechanism is arranged between the body and the drill chuck and used for axially limiting the drill chuck, and the problems that in the prior art, when a through hole is drilled in a skeleton, damage is caused to soft tissue and periosteum due to over-drilling, and over-drilling during skull drilling is avoided are solved.

Description

technical field [0001] The invention belongs to the technical field of medical surgical instruments, in particular to an electric bone drill. Background technique [0002] Orthopedic drills (abbreviated as bone drills) are widely used in hospital orthopedics and neurosurgery. Bone drills are used in fracture treatment operations, internal fixation or external fixation, and in neurosurgery intracranial operations. Drill holes. [0003] In orthopaedic surgery, the doctor will first determine the drilling depth according to the X-ray film, and then cooperate with the relevant instruments to carry out the drilling operation. The drilling depth is the diameter of the bone, but the drill bit is cylindrical, so when the bone is completely drilled, local over-drilling cannot be avoided. Once the over-drilling cannot stop the rotation of the drill bit in time, the idling of the drill bit will affect the periosteum and soft tissue. It will cause more damage, increase the risk of sur...
