Abstract
The utility model relates to an osteotomy device for a pollex valgus surgery with light weight and easy operation. By power supply and a fixable motor, a driving soft shaft which has strong randomness and free angle transforming beneficial to the operation is connected in an operating handle which has no motor and light weight, and a revolving middle shaft, a fixture handle, and the cutting head of the osteotomy device for the chuck of the fixture are mutually connected. The operation is easier by turning the fixture handle, and the time for replacing the cutting head is short.
Description
Affiliated technical field;
This utility model relates to a kind of osteotomy apparatus in the treatment of surgery intoe.
Background technology:
At present, the intoe treatment is just needing the osteotomy sedan-chair, in the past electric drill osteotomy that adopt in this operating process more, because the electric drill motor volume is big, Heavy Weight, in the manipulation process in handle the place ahead, be difficult for grasping and operation, and high speed rotating arranged, cause infringement, the damage of operation surrounding tissue when not noting at the dop position.In the bit change-over process, need dop key lock dop, waste time and energy, increased operating time.
Summary of the invention:
Big in order to overcome electric drill osteotomy volume, Heavy Weight, not easy to operate, cause and pay damage, long shortcoming of bit change time more, this utility model provides a kind of intoe osteotomy device, this osteotomy device flexible operation, in light weight, be easy to grasp, the damage probability is little, and more bit change is convenient, thereby be convenient to operation, the time shortens.
The scheme that its technical problem that solves this utility model adopts is: motor is located at the rear of operating grip, spreads out of power by a kind of flexible axle on operating board, can change direction arbitrarily, links with rotating middle shaft in the osteotomy device handle.The handle forward part is provided with the dop of rotary switch; make osteotomy bit or bit change-over; load and unload more convenient; it is replaceable osteotomy bit or drill bit that rotary switch only need rotate not enough half-turn; rotation dop the place ahead is provided with the metal shell protector; only there are knife bar and cutter head to enter to step on switch (7) and attaching plug (8) UNICOM; there is variable resistance to regulate electric current in the foot switch (6); change motor (6) rotating speed; stepping switch rear motor (6) rotates; flexible axle (5) spreads out of; drive rotating middle shaft (12) rotation in the handle, dop (9) rotates with osteotomy bit (1), implements osteotomy.In embodiment illustrated in fig. 2; osteotomy device bit (1) links to each other with dop (9) by protection handpiece case (2) center; dop (9) gos deep into rotating middle shaft (12) internal cavity; spring (10) is housed can make dop (9) flexible; bearing (11); (13) fixing rotating middle shaft (12); rotating middle shaft (12) is inside and outside two-layer; rotate synchronously; the removable promotion dop of internal layer (9); spring (14) oppositely promotes rotating middle shaft and takes over a business (15); make rotary fixture handle throw-out collar (16) promote rotating middle shaft during rotary fixture handle pushing top disk (17) rotation and take over a business (15) rotating middle shaft (12); internal layer moves promotion dop (9) can make dop (9) flexible; rotating middle shaft commissure portion (18) and flexible axle commissure portion (19) interconnect at osteotomy device handle (4).
Jig dop (9) is that pintongs is cylindrical in embodiment illustrated in fig. 3, and rotating middle shaft is taken over a business outwards extension of (15) pushing and withstanding jig dop (9), changes and places drill bit, and jig dop (9) return dwindled when rotating middle shaft was taken over a business (15) retraction, blocked drill bit.
In embodiment illustrated in fig. 4; Make rotary fixture handle throw-out collar (16) move forward 4 millimeters when spending with rotary fixture handle pushing top disk (17) rotation 170, the promotion rotating middle shaft is taken over a business (15) and is moved.Row rotary-cut osteotomy, thus make operation safer.
The beneficial effects of the utility model are: osteotomy device operation part is in light weight, the little easy operating of volume, and dop more bit change is fast, shortens operating time, and protecting sheathing is arranged before the dop, and safety is simple in structure.
