The utility model relates to the technical field of
medical instruments, and discloses an
orthopedic surgery drill which comprises an electric
drill body, an adjustable clamp is fixedly installed at the output end of the electric
drill body, a drill rod is detachably installed on one side of the adjustable clamp, and a
handle is fixedly installed at the bottom of the electric drill body. A battery is installed in the
handle in a penetrating mode, a bottom cover is installed at the bottom of the
handle in a clamping mode, a groove is formed in the surface of the handle, a clamping head is fixedly installed on the inner wall of the groove, and a clamping hole corresponding to the clamping head is formed in the bottom cover. According to the
orthopedic surgery drilling device, the bottom cover is connected with the handle in a clamped mode through the clamping head and the clamping hole, meanwhile, the
rubber ring can abut against the interior of the limiting frame, after the bottom cover and the handle are clamped, the
rubber ring can be extruded to deform, the
rubber ring can seal a gap between the bottom cover and the handle, and therefore liquid
permeation is prevented, and the sealing performance of a battery opening of the handle is also improved.
