Abstract
The utility model relates to a big toe valgus osteotomy device. A bone saw is mainly used by the existing osteotomy tool of department of orthopedics. Because the bone saw is hand-operated and the operation time is long, the operation time is long, and thus patients get more pain. The utility model comprises an osteotomy knife 1 which is fixed through a quickly arranged clamping head 2. A tail clamp 3 of the quickly arranged clamping head 2 is connected with an output shaft of a speed regulating motor through a shaft coupler 4. A motor 5 and the quickly arranged clamping head 2 are arranged in a handle type housing 6 and the osteotomy knife 1 is a cutting drill head 1. The utility model is an osteotomy bone apparatus, which is used for treating protruded foot bones.
Description
This utility model relates to a kind of osteotomy apparatus that foot's apophysis goes out for the treatment of.
Existing orthopaedics osteotomy instrument mainly is to adopt bone saw.Because be manual operations, the operating time is long, causes operating time long, the patient suffering is many.
The purpose of this utility model is to provide a kind of foot hallux valgus osteotomy device, utilizes the driven by motor cutting element, and is convenient, fast, can reduce patient's misery.
The purpose of this utility model is achieved in that
Foot hallux valgus osteotomy device, its composition comprises: osteotome, described osteotome is fixed by the fast-assembling dop, the tail cartoon of described fast-assembling dop is crossed shaft coupling and is connected with the output shaft of buncher, described motor and fast-assembling dop are installed in the handle type shell, and described osteotome is a cut drill.
Above-mentioned foot hallux valgus osteotomy device, described fast-assembling dop is the three-chip type dop, described dop and rotary sleeve between limit spring is housed, the middle part of described dop has intermittent screw thread, the intermittent screw thread of the rotary sleeve on described intermittent screw thread and the described shell links to each other.
Above-mentioned foot hallux valgus osteotomy device, the diameter 1-4mm of described drill bit has the side cutting blade.
Advantage of the present utility model is:
1. pass through electronic cutting edge, motorized, mechanized operation, so osteotomy speed is fast, compares with traditional manual bone saw, can reduce the osteotomy time more than 50%.Therefore reduce patient's operating time, alleviated patient's misery.
2. adopt hand saws usually can be subjected to the restriction of operating position, the external form of this product can be easily in the operation of any locus just as handle.
3. osteotome is between osteotomy drill bit and the driving device, can adopt general quick-mounting clamp header structure, can turn rotary sleeve 9 as required, compression spring when rotating rotary sleeve, with dop to when extrapolation, the three-chip type dop unclamps naturally, otherwise will block cut drill, and tail is stuck in the interior outwards slip of chute of shaft coupling.Can change rust or the undesirable drill bit of thickness so easily, reduce unnecessary time, intermittent screw thread is in Light Condition when this product is worked, and is in connection status when changing dop.
4. the diameter of drill bit can reduce the bone loss in the 1-4mm scope, reduces painful.
Accompanying drawing 1 is a structural representation of the present utility model.Accompanying drawing 2 is A-A views of accompanying drawing 1.
Be further described below in conjunction with accompanying drawing:
Embodiment 1:
Foot hallux valgus osteotomy device, its composition comprises: osteotome 1, described osteotome 1 is fixing by fast-assembling dop 2, the tail card 3 of described fast-assembling dop 2 is connected by the output shaft of shaft coupling 4 with buncher 5, described motor 5 and fast-assembling dop 2 are installed in the handle type shell 6, and described osteotome 1 is a cut drill 1.
Embodiment 2:
Above-mentioned foot hallux valgus osteotomy device, described fast-assembling dop 2 is the three-chip type dop, between described dop 2 and the rotary sleeve 9 limit spring 7 is housed, the middle part of described dop 2 has intermittent screw thread 8, and the intermittent screw thread 8 of the rotary sleeve 9 on described intermittent screw thread 8 and the described shell 6 links to each other.When rotating rotary sleeve 9 compression springs 7, when extrapolating, the three-chip type dop unclamps naturally, otherwise will block cut drill with dop 2.
Embodiment 3:
