Description

A kind of pliers that titanium plate is bent

Technical field

The utility model relates to the field of medical instrument technology, more specifically, it relates to a kind of pliers that titanium plate is bent.

Background technique

Jaw fracture caused by traffic and engineering accident is clinical common disease, early treatment for patient's functional rehabilitation extremely It closes important.The treatment method used both at home and abroad for fracture of mandible at present mainly has Arch bar splint ligation intermaxillary traction and use Fixed plate fixes two kinds.It is the modus operandi of wide clinical application using fixed plate Internal immobilization, however due to mandibular solution The particularity of mechanism is cutd open, the anatomical reduction and fixation in operation are very difficult, need repeated multiple times adjustment, some cases are postoperative also to be wanted Make intermaxillary traction, this accuracy positioned when not only influencing fixed extends operating time, it is also possible to bring to patient lifelong Functional disability.

When bending, chin portion, cheekbone alveolar ridge and lower molar back zone and nearly middle cheek side, these position shapes are uneven, titanium Plate bends relatively difficult, needs to design a kind of pliers and directly bends and clamp together molding, accelerates operation progress, fracture fixation is used for titanium Plate forming.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of pliers that titanium plate is bent, Have the characteristics that pincers beak is interchangeable and it is convenient to clamp together.

To achieve the above object, the utility model provides following technical solution:

A kind of pliers that titanium plate is bent, including pincers beak, joint and handle, the pincers beak are detachably connected with the joint, The joint is fixedly connected with the handle；The pincers beak includes roller plate and positioning plate, is slidably connected on the positioning plate The roller plate；The roller plate includes roller body and the slide post that is slidably connected with the positioning plate, on the positioning plate It is provided with locating piece, location hole and sliding slot, the sliding slot is arranged at left and right sides of the positioning plate, the location hole and the pass Section connection, the locating piece are arranged on the positioning plate and the location hole opposite side.

By using above-mentioned technical proposal, being detachably connected for beak and joint is clamped, the titanium of different shape specification can be bent Plate, it is all to replace not since chin portion, cheekbone alveolar ridge and lower molar back zone and nearly these position shapes of middle cheek side are uneven Same pincers beak is bent, and is bent when bending using the idler wheel rolling form completion in roller plate, so as to make to form Titanium plate angle more balance and reduce bend during to titanium plate generate mechanical damage, sliding slot and slide post presence limit The movement of system pincers beak, avoids the transition of titanium plate from bending, location hole and arthrodesis can be in order to bend titanium plate, this pliers It directly bends and clamps together molding, accelerate operation progress.

Further, the roller plate is connect with the prismatic, and described roller plate one end is provided with dovetails, described Corresponding dovetail groove is provided on joint, the roller plate and the joint are also fixed by screw, the intra-articular setting There is sawtooth.

By using above-mentioned technical proposal, dovetails are set and dovetail groove is convenient for the dismantling connection of roller plate and joint, together When fix along with screw, avoid pincers rostral displacement when in use, improve the stability bent.

Further, raised plate is provided in the roller plate, the positioning plate and the joint threaded connection place are arranged There is washer.

By using above-mentioned technical proposal, raised plate is that the raising that bends of titanium plate relies on, while improving the rail that titanium plate is bent Road, the washer added prevent positioning plate and joint junction from loosening, and ensure that firm when clamping together.

Further, the middle handle is provided with limited post.

By using above-mentioned technical proposal, limited post is also prevented from what palm was held convenient for the palm positioning when bending Past is forward, and bad force mitigates the difficulty bent.

Further, non-slip texture is provided on the handle.

By using above-mentioned technical proposal, the setting of non-slip texture can increase friction, avoid rubber sleeve mistake when in use Position.

In conclusion can bend not the utility model has the following beneficial effects: pincers beak and joint are detachably connected The titanium plate of similar shape specification, since chin portion, cheekbone alveolar ridge and lower molar back zone and nearly these position shapes of middle cheek side are uneven, It is all to replace different pincers beaks and bent, it is bent when bending using the idler wheel rolling form completion in roller plate, So as to balance molding titanium plate angle more and reduce bend during to titanium plate generate mechanical damage, sliding slot and The movement of the presence limitation pincers beak of slide post, avoids the transition of titanium plate from bending, location hole and arthrodesis can be in order to titanium plates Bend, this pliers, which is directly bent, clamps together molding, accelerates operation progress, and dovetails and dovetail groove is arranged and is convenient for roller plate and joint Dismantling connection avoid pincers rostral displacement when in use, improve the stability bent, raised plate while along with screw is fixed It is relied on for the raising that bends of titanium plate, while improving the track that titanium plate is bent, the washer added prevents positioning plate and joint junction It loosens, ensure that firm when clamping together, limited post is also prevented from the past that palm is held and leans on convenient for the palm positioning when bending Before, bad force mitigates the difficulty bent, and the setting of non-slip texture can increase friction, avoids rubber sleeve dislocation when in use.
