Description

Dismountable type charging bone drill

This utility model relates to a kind of bone drill, is a kind of dismountable type charging bone drill specifically.

Bone drill on the medical market roughly divides three classes at present: manual class, pneumatic class and electronic class.Though manually class is available whenever and wherever possible, because hand fluctuation of service, labor intensity is big, and speed waits reason slowly, so seldom use.It is more that pneumatic class large hospital with good conditionsi is abroad used, but domestic because of the condition limit is not supplied with the possibility of dying as having central nitrogen supply system, single bottle, and compressed air does not reach aseptic requirement so seldom use.Homemade electric bone drill adopts the direct current electric hand drill that has commutator, and controls with foot switch.DE-2 type electric bone drill as Surgical Instruments No.6 Factory, Shanghai, live wire connects vertoro during use, move inconvenience in the operation, foot switch may open by mistake the accidental injury that causes patient or patient, electric drill can not high-temperature sterilization, can not soaking disinfection, and the fumigation sterilization easily makes the electric drill oxidation, the fumigation disinfecting time is long, and postoperative cleans difficulty.The electric bone drill of import costs an arm and a leg.

The purpose of this utility model is to provide a kind of safe and convenient to use, the easy dismountable type charging of sterilization bone drill.

To achieve these goals, this utility model adopts following technical scheme: a kind of dismountable type charging bone drill, comprise main frame, it is characterized in that: main frame is provided with the cloth cover outward, the head of main frame is provided with the chuck molectron, and this chuck molectron is combined into by main shaft, axle sleeve, cloth cover rotating disk, chuck and the spring catch that is located on the main shaft, and one of main shaft is installed in the main frame, the other end suit axle sleeve of main shaft, cloth cover rotating disk and chuck are sleeved on the axle sleeve.

Good effect of the present utility model is: main frame and chuck molectron adopt the dismountable type structure, make the sterilization of chuck molectron convenient on the one hand, and main frame needn't be sterilized on the other hand, has prolonged the service life of main frame; Output shaft adopts the spring catch structure with the shaft room that is sleeved on, and is easy to install and use; Cloth cover head is fixed on the rotating disk, and making between cloth cover and turning cylinder does not have friction, and makes and do not have sterilization section can not expose, and realizes the sterile working.

Below in conjunction with drawings and Examples this utility model is elaborated.
