Detailed description of the invention

In order to technical characteristic of the present utility model, purpose and effect are more clearly understood from, now comparison accompanying drawing describes detailed description of the invention of the present utility model in detail.

As shown in Figures 1 and 2, fracture of medial malleolus in one preferred embodiment of this utility model resets and fixed guide includes intersecting and first hinged caliper the 1, second caliper 2, first caliper 1 includes the first in command's the 11, first clamping limb 12 being positioned at two opposite ends, and the second caliper 2 includes the second in command's the 21, second clamping limb 22 being positioned at two opposite ends. First clamping limb the 12, second clamping limb 22 is respectively equipped with and is held on fracture both sides the tapered end 13 being held in position, binding clip 23; Being provided with mean for drill bit on tapered end 13 and pilot hole that locking part passes through and leads, drill bit is sealed by locking part after the fracture of fracture departs from part and the boring of internal malleolus main body.

It is provided with between the first in command 11, the second in command 21 and provides elastic force to keep the elastic component 3 that first clamping limb the 12, second clamping limb 22 separates, when not in use, make tapered end 13, binding clip 23 automatically separate, it is to avoid to collide interference each other, cause damage.

Binding clip 23 is stretched out to tapered end 13 side by the end of the second clamping limb 22, and and L-shaped between the second clamping limb 22, the free end of binding clip 23 is tip. The coverage when structure of binding clip 23 reduces volume and rotates, it is simple to extend in health and clamp. Certainly, in other embodiments, C-shaped after being connected between binding clip 23 with the second clamping limb 22, or other structures, it is simple to internal malleolus main body is clamped.

Further, the end that tapered end 13 is corresponding with binding clip 23 is that taper is easy to tapered end 13 and is extend in health, and and binding clip 23 1 work and clamp. In other embodiments, the end that tapered end 13 is corresponding with binding clip 23 is alternatively other shape. Pilot hole is passed by most advanced and sophisticated one end of tapered end 13 taper, it is simple to directly boring and locking after clamping.

In certain embodiments, tapered end 13 includes the outer sleeve 131 that is connected with the first clamping limb 12 end and can to the inner sleeve 132 being arranged in outer sleeve 131 with deviating from away from binding clip 23 one end. The endoporus of inner sleeve 132 forms the first pilot hole 1321 that drill bit is led, and the endoporus of outer sleeve 131 forms the second pilot hole 1311 to locking part guiding. When the fracture disengaging part of fracture is less, at tapered end 13 and binding clip 23 from after sandwich, first can depart from part side on the bone of fracture boring through the first pilot hole 1321 from fracture with the drill bit that profile is less, be drilled after inner sleeve 132 is taken out and through the second pilot hole 1311, fracture disengaging part and internal malleolus main body are connected fixing by locking part bigger for the profile such as screw, draw point.

In boring and locking process, the position of tapered end 13 and binding clip 23 is all without movement, the fracture of fracture departs from part and internal malleolus main body be mutually located from the clamping maintenance of biphase dorsal part, can ensure that boring is corresponding with sealed position, both step had been saved, add again accuracy, be particularly well-suited to fracture disengaging part is less when being inconvenient to hole and lock.

First pilot hole 1321 is clear opening, and the direct of travel for drill bit leads. In other embodiments, the first pilot hole 1321 is alternatively the small bore end bellmouth in one end corresponding with binding clip 23, facilitates drill bit to insert and leads.

On ensureing that the inner end positions of the first pilot hole 1321 of inner sleeve 132 and fracture disengaging part are just corresponding, the outer wall of inner sleeve 132 is provided with the positioning table limiting the position inserted in outer sleeve 131, avoid the mistake that inner sleeve 132 is inserted deep or excessively shallow, the position of impact boring.

Preferably, the second pilot hole 1311 is shoulder hole, and place, little profile hole end is corresponding with binding clip 23, is locked in the hole that drill bit bores by little profile hole for the locking part such as screw, draw point. Positioning table is corresponding with the step surface position of the second pilot hole 1311, allows the step surface of the second pilot hole 1311 coordinate with positioning table and realizes the spacing of inner sleeve 132. The profile of inner sleeve 132 is the ladder tubulose corresponding with the profile of shoulder hole, and the body section of big profile forms the step surface of positioning table and the second pilot hole 1311 and coordinates.

The step surface of the second pilot hole 1311 is taper surface, it is possible to facilitate inner sleeve 132 to be inserted in outer sleeve 131. Simultaneously, the end that the non-bulging outer sleeve in end 131 that inner sleeve 132 is corresponding with binding clip 23 is corresponding with binding clip 23, insert before and after outer sleeve 131 at inner sleeve 132, all the time the clamping to fracture disengaging part is realized by outer sleeve 131, ensure that the stability of clamping, the skew of clip position will not be caused due to secondary clamping.

As it is shown on figure 3, in other embodiments, tapered end 13 is alternatively integral mechanism, is provided only with a pilot hole, sealed after fracture departs from after being undertaken holing and supply locking part to put into by this pilot hole part and the boring of internal malleolus main body. When only one of which pilot hole, pilot hole can be suitable with drill bit size, it is possible to bigger than drill bit, by other keepers, the bore position of drill bit is positioned.

It is to be appreciated that above-mentioned each technical characteristic can use and unrestricted in any combination.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
