Abstract
The utility model relates to the technical field of medical instruments, in particular to a tibia far-end rear-side locking bone fracture plate. The bone fracture plate is in an irregular shape and comprises a head and a body which are integrally formed. The head is provided with a plurality of positioning through holes where the bone fracture plate is arranged in advance. The head is provided with a plurality of head screw locking holes, and screws can keep away from a joint face after being installed into the head screw locking holes. The body is provided with a plurality of body screw locking holes. According to the tibia far-end rear-side locking bone fracture plate, angles of the screws are preset through a locking mechanism so that the screws can keep away from the joint face, fixing is safer, special angulation stability of an LCP steel plate is provided for bone fracture fixing, particularly, the osteoporotic fracture and splintered fracture are fixed more firmly, the judgment on screw prebending and imbedding direction during operation is omitted, and the operation is simplified; in addition, the error that the screws are placed into joints by mistake or the errors caused by selecting the length and placing position of the steel plate are reduced, and operation safety is improved.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of distal tibial rear side locking bone fracture plate.
Background technology
Along with developing rapidly of social economy's level, transportation, damage by high-energy the Pilon fracture causing increasing.Pilon fracture is one of the most complicated intra-articular fracture type, incidence rate accounts for 7% of distal tibial fracture, 20%-25% merges open damage, often subsides with articular surface and metaphysis pulverizing and compression in various degree, and be compared with the challenging classification of fracture of tool on current clinical treatment.Due to the difference of the residing position of foot and violence direction and energy when injured, cause complexity and the multiformity of Pilon fracture performance.The main sclerite of Pilon fracture concentrates on front side, rear side, inner side and the outside of tibiofibula far-end complex, research shows, Pilon fracture far-end rear side fracture is the most complicated, because steel plate placement location approaches articular surface more, in operation process, increase pre-bending and inserted the difficulty of screw orientation judgement, easily occur that screw is strayed into joint or selects steel plate length and placement location error, finally causes various complication.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the difficulty that has increased pre-bending in prior art in fracture of tibia operation process and inserted screw orientation judgement, easily occur that screw is strayed into joint or selects the problems such as steel plate length and placement location error, this utility model provides a kind of distal tibial rear side locking bone fracture plate, by squeeze in advance Kirschner wire location blade plate in positioning through hole, drivescrew in thread lock hole, simplify operation technique, improved the safety of operation.
This utility model solves the technical scheme that its technical problem adopts: a kind of distal tibial rear side locking bone fracture plate, be shaped as abnormal shape, comprise integrated head and body, described head is provided with some positioning through hole that can preset blade plate, described head is provided with some head screws lock holes, described head screws lock hole can make screw avoid articular surface after packing screw into, and described body is provided with some body screw lock holes.
As preferably, described head is provided with three positioning through hole, and described three positioning through hole distributions triangular in shape, utilize leg-of-mutton stability, can make blade plate be firmly fixed.
Particularly, the hole slot formula of described body screw lock hole is hole half formula, a described hole half formula screw hole is made up of oval shape pressurization hole and up big and down small conical bore, described conical bore entire body is double end triangle inner bolt structure, adopt the hole slot of hole half formula can adjust up and down according to the demand in actual operation process the position of screw, guaranteeing under fixing prerequisite, avoiding some important tissue sites as far as possible.
As preferably, the two ends of described conical bore are equipped with chamfering.
The beneficial effects of the utility model are: a kind of distal tibial rear side locking bone fracture plate of the present utility model, realize the preset articular surface of dodging of screw angle by locking mechanism, better provide safety for fixing, for fracture fixation provides the peculiar angulation of LCP steel plate stable, provide more fixing to osteoporotic fracture and syntripsis especially, reduce pre-bending in operation and inserted the judgement of screw orientation, simplify operation technique, simultaneously, reduce and occurred that screw is strayed into joint or selects steel plate length and placement location error, has improved the safety of operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is a kind of distal tibial rear side locking bone fracture plate front view of the present utility model;
Fig. 2 is a kind of distal tibial rear side locking bone fracture plate top view of the present utility model.
In figure: 1. blade plate, 2. head screws lock hole, 3. body screw lock hole, 4. positioning through hole, 1-1. head, 1-2. body, 3-1. oval shape pressurization hole, 3-2. conical bore.
The specific embodiment
By reference to the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with this utility model.
As Fig. 1, shown in Fig. 2, a kind of distal tibial rear side locking bone fracture plate, be shaped as abnormal shape, blade plate 1 comprises integrated head 1-1 and body 1-2, head 1-1 is provided with three positioning through hole 4 that can preset blade plate, three positioning through hole 4 distributions triangular in shape, head 1-1 is provided with some head screws lock holes 2, head screws lock hole 2 can make screw avoid articular surface after packing screw into, body 1-2 is provided with some body screw lock holes 3, the hole slot formula of body screw lock hole 3 is hole half formula, one hole half formula screw hole is made up of oval shape pressurization hole 3-1 and up big and down small conical bore 3-2, conical bore 3-2 entire body is double end triangle female thread structure, the two ends of conical bore 3-2 are equipped with chamfering.
The work process of distal tibial rear side locking bone fracture plate is:
Put into blade plate 1 at fracture, at the head 1-1(of blade plate far-end) positioning through hole 4 in squeeze into Kirschner wire, in order to locate fixation bone fracture plate 1; At the head 1-1(of blade plate 1 far-end) the interior drivescrew of head threads lock hole 2, the interior drivescrew of a multiple hole half formula hole slot 3 on body 1-2, can be according to actual operation situation adjustment screw position.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content in description, must determine its technical scope according to claim scope.
