Hole-forming bone drill used for orthopedics department

Abstract

The invention relates to the technical field of medical apparatus and instruments, and in particular relates to a hole-forming bone drill used for the orthopedics department. The bone drill comprisesa bone drill main body, a drill bit mechanism, a mounting shell, a handle, a cooling mechanism and a distance measurement mechanism, wherein the bone drill main body is horizontally arranged on the mounting shell, a connecting base is arranged at the left end of the bone drill main body, a buffering assembly is arranged between the connecting base and the drill bit mechanism, the drill bit mechanism comprises a mounting base and a bone drill bit arranged in the mounting base, a mounting sleeve is arranged at the right end of the mounting base, the left end of the connecting base is tightly sleeved with a sliding sleeve, and the distance measurement mechanism comprises a fixing bar and a distance display assembly. The hole-forming bone drill has the beneficial effects that through the distance measurement mechanism, the depth of a hole can be measured in real time, and meanwhile, a user can know the depth of the hole through precise scales, so that the injuries caused to the tissue dueto the fact that the bone drill extends into an excessively deep position are avoided; and in addition, through a cooling mechanism, the temperature of the bone drill bit can be reduced, so that the injuries caused to the human tissue due to the fact that the temperature of the outer side of the bone drill bit is excessively high are avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a perforated bone drill used in orthopedics. Background technique [0002] Bone drill is one of the most commonly used equipment in surgical operations, and the quality of the equipment is directly related to the success of the operation. When drilling a hole in a patient's bone, the surgeon usually holds an electric drill to pressurize the drill. During the operation, if the bone drill goes too deep, it may cause tissue damage, and the surgeon needs to use a detector after the hole is drilled. To measure the depth of the drilled hole to determine the appropriate screw, this brings great trouble to the surgeon. When drilling a patient's bone, the friction between the bone drill bit and the bone will generate a lot of heat. If it is not cooled in time, it will easily cause damage to human tissue. The existing cooling method is usually to manually add physiological sal...
