Abstract
The utility model provides a tibia straight type locking plate. The tibia straight type locking plate comprises a plate body, wherein hole grooves are formed in the plate body, the hole grooves are locking and pressurizing holes, the two sides of the plate body are respectively provided with triangular protrusions in a staggered mode, a near end on the plate body and a far end on the plate body are of a semicircular shape and respectively provided with one of the hole grooves, the other hole grooves are formed in the triangular protrusions respectively, a locking hole and a pressurizing hole are partially overlapped to form each locking and pressurizing hole, each locking hole is composed of a counter bore and a conical threaded hole, each pressurizing hole is an arc-shaped counter bore, a pressurizing end is arranged at the end portion of each pressurizing hole, and each pressurizing end has a gradient so that each pressurizing end can better exert pressure on broken bones to enable the broken bones to be jointed. The tibia straight type locking plate has the advantages that the anatomic design is adopted, the requirement for plastotype in an operation is lowered, the stimulation of implantation materials to soft tissue is reduced, and the tibia straight type locking plate has the gradient design which is more suitable for the skeletal structure of an Asian and is an optimum apparatus for the tibia fracture operation in the orthopedic surgery department.
Description
Technical field
This utility model belongs to medical instruments field, especially relates to the straight type lockplate of the orthopedic tibia of a kind of fracture of tibia.
Background technology
In existing bone surgery, need to utilize blade plate and bone screw to implement fracture site fixing, the biomechanics prerequisite of conventional steel plates makes it to have following biology of defect: the compressing periosteum, affect the fracture end blood supply, extend recovery time, simultaneously, the conventional pressurized screw has lighter resistance for shearing force, easily because shearing force is become flexible; Although lock screw has stronger resistance for shearing force, can not pressurize to the knochenbruch face, knochenbruch is in released state, is unfavorable for the knochenbruch healing.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of locked pressurized bone plate, especially is fit to the straight type lockplate of a kind of tibia of orthopedics's fracture of tibia.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the straight type lockplate of a kind of tibia, comprise plate body, plate body is provided with hole slot, the plate body both sides are provided with denation, near-end on plate body and far-end are all that semicircle also respectively has a hole slot, and all the other hole slots are positioned on denation.
Further, described hole slot is the locking compress combination bore.
Further, described denation is interspersed.
Further, bore portion is overlapping forms by lock hole and pressurization for described locking compress combination bore.
Further, described lock hole is comprised of counterbore and conical screw hole.
Further, described pressurization hole is the arcuation counterbore, and end is provided with live end, and the gradient of live end is between 35 degree～45 degree.
Further, the angle of taper of described conical screw hole is between 15 degree～25 degree.
Advantage and the good effect that the utlity model has are:, owing to adopting technique scheme to carry out the anatomical form design, reduced plastotype needs in art, reduced the stimulation of implant to soft tissue, be more suitable for the radian design of Aisan's skeletal structure.And the hole slot on plate body can need combination in any to a certain extent with the client, is the preferred equipment of orthopedics's fracture of tibia operation.

The specific embodiment
As shown in Figure 1, this utility model is the straight type lockplate of a kind of tibia, comprise plate body 1, it is locking compress combination bore 2 that plate body 1 is provided with hole slot, plate body 1 both sides are provided with the denation that is interspersed, near-end on plate body 1 and far-end are all that semicircle also respectively has a hole slot, and all the other hole slots are positioned on denation.The design of employing anatomical form, the needs of plastotype in the minimizing art, be fit to the radian design of Aisan's skeletal structure.
As shown in Figure 2, locking compress combination bore 2 is by lock hole 3 and pressurization hole 4 parts overlapping composition, and pressurization hole 4 be the arcuation counterbore, and end is provided with live end 7, and the gradient of live end 7 is preferably 40 and spends.Lock hole 3 and pressurization hole 4 coordinate lock screw and forcing screw to use, and can better the rear locking of pressurizeing of patient's fracture of tibia position correct knochenbruch and engage, and promote successful surgery.
As shown in Figure 3, lock hole 3 is comprised of counterbore 5 and conical screw hole 6, and the angle of taper of conical screw hole 6 is preferably 20 degree, and locking effect is better.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to this utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
Claims (7)
