Abstract

The utility model relates to a medical instrument, in particular to a portable multifunctional bone surgical instrument. The portable multifunctional bone surgical instrument comprises a handheld DC motor, a skull drill bit, a skull mill head, a bone saw head, and a bone drill chuck, wherein both of the skull drill bit and the bone drill chuck are connected with the other end of one transformer and with the output end of one transformer; the other ends of the transformers are respectively connected with one connector; and the other ends of the connectors are fast interfaces fitting the output shaft of the handheld DC motor. Through the connectors and the transformers with the universal fast interface, various kinds of instrument heads can be fast connected with the handheld motor in a replaceable manner so as to achieve multiple purposes and lowered cost, facilitate the use, and meet the requirement for field treatment. Each part made of stainless steel material has improved resistance to corrosion and aging.

Description

A kind of portable multi-function bone surgery apparatus

Technical field

This utility model relates to a kind of medical apparatus and instruments, specifically is a kind of portable multi-function bone surgery apparatus.

Background technology

Bone surgery is an important content of battlefield treatment, produce and allot the bone surgery apparatus of army at present both at home and abroad, all adopt bulky pneumatic and electronic strength to do power, be transferred to clamper by flexible axle and undergo surgery, operation is inconvenience very, and more the incompatibility field operations need.Portable bone saw, cranial drill, the skull of at present existing simple function mill and the bone drill dop, because the rotating speed that the apparatus of different operations requires is not quite similar, the interface between each apparatus can not be general, cause using inconvenience, costing an arm and a leg.

Summary of the invention

The head that the purpose of this utility model just provides a kind of each apparatus all has unified interface, and according to the operation needs variator is set, can a tractor serves several purposes, cheap portable multi-function bone surgery apparatus.

For achieving the above object, the technical solution adopted in the utility model is: comprise hand-held direct current generator, skull drill bit, skull milling head, bone saw head, bone drill dop, described skull drill bit all is connected with the outfan of a variator with the other end of a variator with the bone drill card, the other end of this variator connects an adapter respectively, and the other end of described adapter is the fast interface that cooperates with the output shaft of described hand-held direct current generator.The output shaft rotating speed of described hand-held direct current generator is about 18000-20000rpm, and the outfan speed of described variator is about 550-650rpm.Described handheld electrical machinery, skull drill bit, skull milling head, bone saw head, bone drill dop, the shell of adapter and variator is made by rustless steel.

Adapter and the variator of this utility model by having quick unified interface, various apparatus heads can be changed fast with handheld electrical machinery to be connected, realize the purpose of a tractor serves several purposes, reduction price, also made things convenient for use, satisfied the requirement of field condition treatment, each parts of stainless steel material have improved corrosion-resistant, ageing resistace.
