Abstract
The utility model relates to a bone fixing clip. The bone fixing clip comprises a main body, wherein the front end of the main body is forked to form two elastic clips with the trend of flicking towards the outer side; the two elastic clips are connected through an articulating block; and the articulating block is provided with a breakable part which can be broken when the end part of the main body is knocked. According to the bone fixing clip, the front end of the main body is forked to form the two elastic clips with the trend of flicking toward the outer side, the two elastic clips are connected through the articulating block, and the articulating block is provided with the breakable part which can be broken when the end part of the main body is knocked, so that bone can be pressed in two or more opposite directions when the bone fixing clip is applied to internal fixation, the connecting and fixing effect between the fracture sections can be obviously improved, bone healing is fastened, patients can be recovered early and pain of patients is reduced. The bone fixing clip is novel, reasonable and simple in structure, good in fixing effect during application and low in cost, and is worthy of popularizing.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of fixedly bone fixation spring tab of usefulness of bone that is used for.
Background technology
Fracture is meant seriality and the partially or completely destructive a kind of disease of integrity quilt that causes bone owing to reasons such as wound or pathology.Reset, fix, functional exercise etc. is main fractures step.In bone surgery, can correct or fix bone by means of various implantation instrument usually, impel normal healing of fractures potential energy and restore funcitons.The steel plate shell fragment is a kind of internal fixation device commonly used, and present steel plate shell fragment on the market is crooked lamellar or directly tabular, during fixing the use, the hammering of steel plate shell fragment is fixed to sclerotin.Keep certain pressure making under the effect of steel plate shell fragment between folding end, can promote union of fracture.But for osteoporotic patient, because bone trabecula attenuation in the spongy bone, sparse even disappear, adopt that the steel plate shell fragment is fixing to be occurred local constant intensity not enoughly easily, be prone to situations such as cutting, loosening, displacement after fixing, cause fixing operation to fail.Therefore, be badly in need of to occur a kind of constant intensity higher, be difficult for loose shift and safe and reliable bone fixation spring tab to satisfy the present situation demand.
Summary of the invention
This utility model will solve the shortcoming of above-mentioned prior art, provide a kind of constant intensity higher, be difficult for loose shift and safe and reliable bone fixation spring tab, satisfy the demand of internal fixation operation.
This utility model solves the technical scheme that its technical problem adopts: this bone fixation spring tab; Comprise main body; This body front end bifurcated; Form two and have the flexure strip that flicks trend laterally, two flexure strips link together through being connected piece, and this linking piece is provided with the easy breaking off section that when body end is knocked, can rupture.Like this, when doing internal fixation operation, the passage hammering that the flexure strip end alignment of cylinder front end is offered is in advance entered to get final product; In the hammering fixation process, the easy breaking off section that is connected on the piece breaks off naturally, and the flexure strip nature opens to both sides; Again progressively along with hammering is fixed in the sclerotin on the both direction, can make the skeleton effect that on two or more rightabouts, can both be under pressure, can obviously improve the fracture site constant intensity; Avoid occurring phenomenons such as cutting, loosening, displacement; More help further improving fixation intensity when cooperating bone cement or curable bone-grafting material to use, promote the bone healing growth, so that early ambulant even heavy burden.
Further, the side that is connected piece is the hourglass shape, and the cervical region of hourglass is described easy breaking off section.Like this; The easy breaking off section of hourglass neck shaped will be narrower than or be narrower than other positions that are connected piece; Make the fracture strength of this easy breaking off section be lower than other positions that are connected piece; Thereby this easy breaking off section that is connected on the piece can be broken off naturally, help when doing internal fixation two flexure strips and can in time separate and peg graft fixing to different directions.
Further, main body not forked section be provided with the guide pinhole of perforation.Like this, can cooperate guide pinhole guiding bone fixation spring tab to fix, improve the precision of fixing operation, thereby improve success rate of operation through guide pin.
Have symmetrically arranged guide pin slot on the two flexure strip opposite faces, guide pinhole communicates with guide pin slot.When being convenient to the bone fixation spring tab like this and installing and fixing and the guide pin close fit, it is fixing to help guiding, improves the operation precision.
The effect that this utility model is useful is: this utility model rational in infrastructure, simple; Through bone fixation spring tab body front end bifurcated two of formation are set and have the flexure strip that flicks trend laterally; And two flexure strips link together through being connected piece, and this linking piece is provided with the easy breaking off section that when body end is knocked, can rupture, and make this utility model when being applied at internal fixation operation, can make the skeleton effect that on two or more rightabouts, can both be under pressure; Can obviously improve the connection fixed effect between fracture face; Help accelerating bone healing, help patient's early recovery, reduce patient's pain.This utility model novel structure, good fixing effect during application, cost is lower, is worthy to be popularized.

Description of reference numerals: main body 1, flexure strip 2 is connected piece 3, easy breaking off section 3-1, guide pinhole 4, guide pin slot 5.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further:
With reference to accompanying drawing: this bone fixation spring tab in the present embodiment; Comprise main body 1; This main body 1 front end bifurcated; Form two and have flexure strip 2, two flexure strips 2 that flick trend laterally and link together, the easy breaking off section 3-1 that this linking piece 3 can rupture when being provided with and being knocked in main body 1 end through being connected piece 3.
The side that is connected piece 3 is the hourglass shape, and the cervical region of hourglass is described easy breaking off section 3-1.
Have symmetrically arranged guide pin slot 5 on two flexure strips, 2 opposite faces, guide pinhole 4 communicates with guide pin slot 5.
Linking piece 3 in this utility model can be used to connect the syndeton of flexure strip 2 for solder joint or bond pad or other, and this syndeton is provided with the easily broken structure that can rupture when being knocked in main body 1 end.
The structure that easy breaking off section 3-1 in this utility model can rupture in the time of can also be knocked in main body 1 end for ease of impression or the concave face of fracture or other.
When internal fixation operation, set up bone property passage in advance, fix according to guide pin or this bone of the spacing importing of Kirschner wire; The hammering bone is fixing again inserts, and linking piece 3 is pulled apart, and flexure strip 2 natures open to both sides; Along with hammering fixation spring tab progressively, each flexure strip 2 inserts to different directions, makes fracture site receive the pressure effect of a plurality of directions; Can obviously improve the fracture site constant intensity, avoid occurring phenomenons such as cutting, loosening, displacement, more help further improving fixation intensity when cooperating bone cement or curable bone-grafting material to use; Promote the bone healing growth, so that early ambulant even heavy burden.
Though this utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
