Bone debris splash preventing bone drill

Abstract

The invention belongs to the technical field of orthopaedic surgeries, and particularly relates to a bone debris splash preventing bone drill. One end of an electric drill is connected with a rotating shaft, and the other end of the electric drill is connected with a handle; a drill bit is arranged on the rotating shaft; the bone debris splash preventing bone drill is characterized by also comprising a bone debris protective device, wherein the bone debris protective device comprises a protective cover arranged between the drill bit and the electric drill and an auxiliary protective shell; the drill bit penetrates through the protective cover; the protective cover is adjacent to the drill bit; the lower end of the protective cover is provided with a guide slot communicated with the protective cover; the guide slot is connected with the auxiliary protective shell through a connecting tube; openings are respectively formed between the connecting tube and the guide slot and between the guide slot and the auxiliary protective shell; a debris poking gear is arranged in the auxiliary protective shell; the rotating shaft penetrates through the center of the debris poking gear; the auxiliary protective shell is communicated with a guide tube positioned below the auxiliary protective shell. The bone debris splash preventing bone drill has the beneficial effects that bone debris generated in the using process of the bone drill can be effectively prevented from splashing, the influence to an operator is reduced, an operation technique is more accurate, and the safety of a patient is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of orthopedic surgery, and in particular relates to a bone chip anti-splash bone drill. Background technique [0002] Existing medical bone drills are similar in structure to common electric drills, including electric drills and drill bits. During bone trauma surgery, it is necessary to punch holes in the essence of the bone. Rapid movement and splashing around not only pollute the environment, but also easily splash on the operator. It is unsafe to use, affects the doctor's operation on the patient, increases the risk of the operation process, and also brings troubles to debridement. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a bone chip anti-splash bone drill, which can effectively prevent the bone chips generated during the use of the bone drill from splashing around, reduce the impact on th...
