Problems solved by technology
If the drill bit passes through the bone tissue, if it is not stopped immediately, it will often injure other human tissues around the bone, resulting in more serious injuries; Very practical clinical significance
On the other hand, the drill bits currently used in orthopedics basically follow the structure of straight-shank twist drills, which will generate a lot of debris when drilling bone. Once these debris stick to soft tissue, it is difficult to wash away. It increases the difficulty of work for medical staff, and also increases the pain for patients

The invention relates to a fragment removal protective bone drill. The fragment removal protective bone drill comprises a shell, a chuck, a main motor, a battery and a switch, and is characterized in that: the front end of the shell is provided with a joint column corresponding to the chuck; the joint column is provided with positioning thread; the bone drill is also provided with a protective sleeve, an air suction module, a suction pipe and a fragment holding box; the protective sleeve comprises a positioning nut seat and a drill bit bushing which are connected with the joint column; the drill bit bushing is provided with a fragment removal hole; the air suction module, the suction pipe and the fragment holding box are arranged on the shell in a matching way; one end of the suction pipe is connected with the fragment removal hole, and the other end of the suction pipe is communicated with the fragment holding box; and the air suction module is arranged on the top of the fragment holding box and is electrically connected with the battery and the switch in the matching way, so that air pressure difference is produced inside and outside the fragment holding box. The bone drill has the beneficial effect of realizing accurate control of drilling depth and timely bone fragment removal.
Description
Technical field [0001] The invention relates to an appliance suitable for orthopedic medical treatment, in particular to a chip-removing and protecting bone drill. Background technique [0002] At present, when a bone fracture accident occurs, the fracture is often treated with a knife, and sometimes the bone needs to be drilled, so a bone drill is needed. The bones of the human body consist of cortical bone with high hardness and high density located on the outer layer, and the inner surface of the cortical bone contains spongy bone with relatively loose bone quality. Therefore, during the operation, the surgeon generally drills holes based on experience and touch operate. If the drill bit passes through the bone tissue, if it is not stopped immediately, it will often injure other human tissues around the bone, resulting in more serious injuries; Very practical clinical significance. On the other hand, the drill bits currently used in orthopedics basically follow the str...
