Abstract
The present invention relates to a kind of posterior cruciate ligament of knee joint femur rebuilding tunnel device for making, comprise one handle holding rod, it is characterized in that: one end of described handle holding rod is vertically fixed with the first abutment sleeve, the other end of described handle holding rod is vertically fixed with the second abutment sleeve, in described the first abutment sleeve, being provided with one can the reciprocating needle-like backstay of relative the first abutment sleeve, on the outer circumferential side of described the second abutment sleeve, be installed with needle-like backstay plays positioning action jointly and turn shape backstay, in described the second abutment sleeve, be provided with Kirschner wire. Simple structure of the present invention, simple operation, can not only effectively simplify the operation course, and instrument use repeatability is high, has greatly ensured subsequent medical operation.
Description
Technical field
The present invention relates to a kind of posterior cruciate ligament of knee joint femur rebuilding tunnel device for making, particularly posterior cruciate ligament of knee joint Reconstruction femur rebuilding tunnel, belongs to medical instruments.
Background technology
Along with high-energy damage, Posterior cruciate ligament patient is ascendant trend year by year. After ligament injury, affect knee Stability, the later stage will cause meniscus, cartilage damage, accelerate Osteoarthritis generation process. Under arthroscope, damage cruciate ligament reconstruction surgery amount also increases thereupon. Operation need to be rebuild and produce femur tunnel, and means and not only complex operation of instrument are produced in existing reconstruction, and repeatable poor. Therefore are, objects that the present invention studies for the problems referred to above.
Summary of the invention
The object of the present invention is to provide a kind of posterior cruciate ligament of knee joint femur rebuilding tunnel device for making, contribute to solve and at present cannot be effectively femur tunnel be carried out to easy operation, instrument are reused etc.
Technical program of the present invention lies in:
A kind of posterior cruciate ligament of knee joint femur rebuilding tunnel device for making, comprise one handle holding rod, it is characterized in that: one end of described handle holding rod is vertically fixed with the first abutment sleeve, the other end of described handle holding rod is vertically fixed with the second abutment sleeve, in described the first abutment sleeve, being provided with one can the reciprocating needle-like backstay of relative the first abutment sleeve, on the outer circumferential side of described the second abutment sleeve, be installed with needle-like backstay plays positioning action jointly and turn shape backstay, in described the second abutment sleeve, be provided with Kirschner wire.
Wherein, described in turn shape backstay the portion of turning become needle-like, and coaxial to the heart with the needle tip of needle-like backstay.
The stack shell of described the first abutment sleeve is provided with a transparent observing window, and the described transparent windows opening's edge needle-like backstay direction of motion is provided with scale.
On the stack shell of described the first abutment sleeve and the second abutment sleeve, be also respectively equipped with a locking button.
The end of the relative needle tip of described needle-like backstay is provided with an end cap.
The invention has the advantages that: simple structure of the present invention, simple operation, can not only effectively simplify the operation course, and instrument use repeatability is high, has greatly ensured subsequent medical operation.
Brief description of the drawings
Fig. 1 is the original state structural representation of the embodiment of the present invention.
Fig. 2 is the working state structure schematic diagram of the embodiment of the present invention.
Detailed description of the invention
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1 and Fig. 2, the present invention relates to a kind of posterior cruciate ligament of knee joint femur rebuilding tunnel device for making, comprise one handle holding rod 1, one end of described handle holding rod is vertically fixed with the first abutment sleeve 2, the other end of described handle holding rod is vertically fixed with the second abutment sleeve 3, in described the first abutment sleeve, being provided with one can the reciprocating needle-like backstay 4 of relative the first abutment sleeve, on the outer circumferential side of described the second abutment sleeve, be installed with needle-like backstay plays positioning action jointly and turn shape backstay 5, in described the second abutment sleeve, be provided with Kirschner wire 6.
The described portion of turning of turning shape backstay becomes needle-like, and coaxial to the heart with the needle tip of needle-like backstay.
The stack shell of described the first abutment sleeve is provided with a transparent observing window 7, and the described transparent windows opening's edge needle-like backstay direction of motion is provided with scale 8.
On the stack shell of described the first abutment sleeve and the second abutment sleeve, be also respectively equipped with a locking button 9.
The end of the relative needle tip of described needle-like backstay is provided with an end cap 10.
Specific embodiment of the invention process: in implementation process, first the Kirschner wire of second abutment sleeve of this device is had good positioning on shin bone, by Kirschner wire, the needle tip that turns shape backstay being connected on the second abutment sleeve is set on shin bone, next utilize the parameter request of having known before operation, the needle tip of the needle-like backstay in the first abutment sleeve is set on femur, wherein realize the observation for length aspect by the scale on the first abutment sleeve, and related locking button can ensure for the fixation for backstay, prevent positioning.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
