Summary of the invention
In view of the above-mentioned problems in the prior art, the object of this invention is to provide a kind of steel plate of can directly placing when the reduction of the fracture is fixed and also can fix anti-skidding four paws bone holder, increase fixed degree, reduce operating time, improve success rate of operation.
The technical problem that this utility model solves realizes by the following technical solutions:
Directly can place a four paws bone holder for steel plate, comprise base, slide, screw rod, described base be provided with the chute being communicated with upper and lower surface; Described slide is arranged on the upper surface of base; The head end of described base and slide is respectively arranged with bone pawl, and the tail end of base is provided with the axis tapped through hole consistent with the direction of chute; The tail end of slide is provided with the axis screw-threaded counterbore consistent with the direction of chute; One end of described screw rod is arranged in the screw-threaded counterbore of slide, and screw rod is through the tapped through hole on base, and the other end of screw rod is provided with nut; The screw thread of the tapped through hole on described screw flight and base and the screw-threaded counterbore on slide matches; Described slide is driven by screw rod, along slide; It is characterized in that: described bone pawl has four, comprise the double end fixed claw being positioned at base head end and the double-end movable pawl being positioned at slide head end; The groove for placing steel plate is provided with in the middle part of described double-end movable pawl.
Described a kind of four paws bone holder directly can placing steel plate, is characterized in that: contain anti-slip veins inside described double end fixed claw and double-end movable pawl.
Described a kind of four paws bone holder directly can placing steel plate, it is characterized in that: described double-end movable pawl is mainlyed grasp by activity and formed with movable auxiliary pawl, the groove central authorities that described activity is mainlyed grasp are provided with tapped through hole, are equipped with the set screw for fixation steel plate in through hole.
Described a kind of four paws bone holder directly can placing steel plate, is characterized in that: the top of described set screw is equipped with steel plate fixer.
Described a kind of four paws bone holder directly can placing steel plate, is characterized in that: described steel plate fixer is the circular gasket be fixedly connected with set screw top.
Compared with prior art, this utility model tool has the following advantages: (1) is inserted conveniently, and double end fixed claw enters from fracture end side, and tissue is peeled off few, is easy to insert.(2) fixed, this bone holder is four paws bone holder, is 4 clamping fracture sites, all can provides firm temporary fixed to transverse fracture, oblique fracture, butterfly bone block etc.(3) steel plate is inserted conveniently, insert without the need to secondary, when bone holding forceps for fracture reduction is fixed, in advance steel plate can be placed on movable major-minor grabs in groove, namely complete inserting of steel plate bone holding forceps for fracture reduction is temporary fixed simultaneously, putting into steel plate without the need to again unclamping bone holder, decreasing operating procedure, reduce operating time.(4) Interal fixation is firm, is not easily shifted, first steel plate be placed in movable major-minor grab in be at 2 and fix, not easily move up and down, secondly movable axial prong is containing steel plate fixer, can by Interal fixation between bone and bone holder, and steel plate is reliable and stable.
