Abstract
The invention provides a medical combined automatic screwdriver comprising a housing. The housing is internally provided with a battery chamber and a motor. The bottom of the housing is provided with a support. The top of the housing is provided with a rotor connected with an output shaft of the motor. The middle of the housing is connected to a handle through a fixing clamp; the handle is integrated to the housing. The rotor is connected with a bit holder in a threaded manner; the bit holder is connected with a screwdriver head. The medical combined automatic screwdriver is convenient to hold by hand, is available in a gun operating mode and a lever operating mode, is operated electrically instead of manually, allows the screwdriver head to be removable and replaceable and is especially suitable for orthopedists to perform professional operations.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of Combined medical automatic screwdriver.
Background technology
At present, medical worker implements internal fixation to Patients with Traumatic Fracture or often can use screwdriver when carrying out orthomorphia to deformation patients, and under prior art, seldom have the medical screw driver of specialty, but with being engaged in the alternative use of normal screws cutter of woodworking, automobile maintenance industry, electrician trade, its drawback is: normal screws cutter completes by manpower rotation process, wastes time and energy; In addition, screwdriver does not possess vertical function of placing, and very easily rolls on operating table, and carrys out lock-screw by lever grip; In addition, its cutter head is fixed structure, and the screw for different nut needs the screwdriver being equipped with the different edge of a knife, and limitation is comparatively large, is therefore necessary to improve.
Summary of the invention
The technical problem that the present invention solves: provide a kind of Combined medical automatic screwdriver, facilitates hand-held and force, adopts electric power to substitute manual operation, realizes the function that cutter head is detachably replaced.
The technical solution used in the present invention: Combined medical automatic screwdriver, there is casing, battery compartment and motor is established in described casing, described bottom of shell is provided with bearing, cabinet top is provided with the rotation be connected with motor output shaft, connected and shell body hand holding handle in a certain angle by geometrical clamp in the middle part of casing, described swivel head is spirally connected cutter head supporting member, cutter head supporting member connecting screw cutter head.
Wherein, described casing is cylindrical, and adopt engineering plastics outer wrapping silicon rubber to make, the adaptive geometrical clamp of its excircle, described geometrical clamp open end is included in the groove that hand holding handle upper end is shaped with hand holding handle and casing to be detachably fixed together, described geometrical clamp top is shaped with and facilitates hand-held projection, and described casing is also provided with motor switch.
Further, the rotary input of described swivel head is connected with rotor output shaft, and the rotary output of swivel head is shaped with screw, and the screw rod adaptation that described screw and cutter head supporting member are shaped with is connected.
The screw rod that described cutter head support member one end is shaped with and swivel head are threaded connection, and the described cutter head support member other end is shaped with insertion tube, and described insertion tube inner bottom part is provided with magnetite, and insertion tube inwall is fusiform structure, described fusiform structure and cutter head inserted terminal suitable.
Described cutter head is a word cutter head or cross cutter head; Described hand holding handle is pistol-hand holding handle.
The present invention's advantage compared with prior art:
1, the operating habit of screwdriver is changed by installation or removal hand holding handle, i.e. gun-type but also traditional pillar, can choice for use according to actual needs, operate hand-held more comfortable, have more hommization;
2, screwdriver rotarily drives cutter head tightening screw by installing battery driven motor rotor, and mechanical force replaces manpower, and lock-screw operation rapidly and efficiently, saves muscle power;
3, cutter head is detachable plug-in type cutter head, and can change corresponding cutter head according to the concrete shape of screw nut, the scope of application is wider.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, a kind of embodiment of the present invention is described.
Combined medical automatic screwdriver, there is casing 1, battery compartment 12 and motor 13 is established in described casing 1, bearing 2 is provided with bottom described casing 1, casing 1 top is provided with the swivel head 3 be connected with motor 13 output shaft, connected and casing 1 housing hand holding handle 8 in a certain angle by geometrical clamp 10 in the middle part of casing 1, described swivel head 3 is spirally connected cutter head supporting member 4, cutter head supporting member 4 connecting screw cutter head 6.The operating habit of screwdriver is changed, i.e. gun-type but also traditional pillar by installation or removal hand holding handle 8, can choice for use according to actual needs, operate hand-held more comfortable, have more hommization; Described casing 1 is cylindrical, and adopt engineering plastics outer wrapping silicon rubber to make, the adaptive geometrical clamp 10 of its excircle, described geometrical clamp 10 open end is included in the groove 9 that hand holding handle 8 upper end is shaped with hand holding handle 8 and casing 1 to be detachably fixed together, described geometrical clamp 10 top is shaped with and facilitates hand-held projection 11, described casing 1 is also provided with motor switch 14, screwdriver rotarily drives cutter head 6 tightening screw by installing battery driven motor 13 rotor, mechanical force replaces manpower, lock-screw operation rapidly and efficiently, saves muscle power; The rotary input of described swivel head 3 is connected with motor 13 rotor of output shaft axle, and the rotary output of swivel head 3 is shaped with screw, and the screw rod adaptation that described screw and cutter head supporting member 4 are shaped with is connected; The screw rod that described cutter head support member 4 one end is shaped with and swivel head 3 are threaded connection, described cutter head support member 4 other end is shaped with insertion tube 5, described insertion tube 5 inner bottom part is provided with magnetite 15, and insertion tube 5 inwall is fusiform structure, described fusiform structure and cutter head 6 inserted terminal 7 suitable.Described cutter head 6 is a word cutter head or cross cutter head; Described hand holding handle 8 is pistol-hand holding handle.Cutter head 6 is detachable plug-in type cutter head, and can change a corresponding word cutter head or cross cutter head according to the concrete shape of screw nut, the scope of application is wider.
Above-described embodiment, just preferred embodiment of the present invention, is not used for limiting the scope of the present invention, therefore all equivalence changes done with content described in the claims in the present invention, all should be included within the claims in the present invention scope.
