Description
Technical field
The utility model relates to the field of medical instrument technology, in particular to posterior cruciate ligament rebuilds guider.
Background technique
Orthopaedics replacement knee posterior cruciate ligament reconstruction art is one of higher operation of difficulty in laparoscopic surgery, is especially existed
It identifies when establishing tibial tunnel behind posterior cruciate ligament of knee shin bone footmark area in the control in direction, the shin bone registration arm of Conventional positioners
End can not accurately capture conduit, so that tibial bone tunnel can not be accurately positioned in operator, or even since tibial bone tunnel positions
Inaccuracy causes the severe complications such as cortex rupture on rear side of proximal tibia to occur, to affect postoperative effect.
Utility model content
The purpose of this utility model is that providing posterior cruciate ligament for above-mentioned problem and rebuilding guider.
To achieve the goals above, the technical solution of the utility model is specific as follows:
Posterior cruciate ligament rebuilds guider, including handle, shin bone registration arm, guider positioning seat, conduit, the guider
It is provided with axial passage on positioning seat, conduit is coupled in the axial passage, the setting of guider positioning seat side is held
The handle side is provided with guide slide, and be slidably connected shin bone registration arm on the guide slide, and the guide slide is logical
The fixed shin bone registration arm of positioning screw is crossed, hook plate, the inside both sides point of the hook plate are arranged in shin bone registration arm end
It is not provided with capture protrusive board.
The guider positioning seat is tile like structure.
Angle α between the hook plate and the shin bone registration arm is 122 degree.
The axial passage two sides of the guider positioning seat are additionally provided with Kirschner wire fixation channel.
The beneficial effects of the utility model are: the utility model on the basis of traditional reconstruction guider, is positioned in shin bone
Hook plate is arranged in arm end, and capture protrusive board is respectively set in both sides on the inside of hook plate, so that the end of shin bone registration arm forms claw knot
Conduit is captured using the claw structure and is fixed, then conduit is fixed by structure, during improving posterior cruciate ligament reconstruction
The accuracy and convenience of positioning, wherein in order to enable to stablize fitting contact in front of guider positioning seat and shin bone, increase steady
Qualitative, guider positioning seat is designed as tile like structure by us, in order to be fixed on guider positioning seat on shin bone, Wo Men
Kirschner wire fixation channel is arranged in the axial passage two sides of guider positioning seat, for being fixed guider positioning seat by Kirschner wire
On shin bone, after measuring 736 health adult's knee joint data, it has been found that Asian tibial plateau intersects tough with after
Band slope stop angle is 122.4 ± 8.1 degree, when by many experiments, we determined that between hook plate and shin bone registration arm
Angle α is 122 degree, is to be suitable for Asian angle the most.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the bottom view of guider positioning seat in Fig. 1.
Fig. 3 is the top view of hook plate in Fig. 1.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, posterior cruciate ligament rebuilds guider, including the positioning of handle 1, shin bone registration arm 2, guider
Seat 3, conduit 4, are provided with axial passage on guider positioning seat 3, and the axial passage two sides of guider positioning seat 3 are additionally provided with gram
Family name's needle fixes channel, and conduit 4 is coupled in axial passage, and handle 1, the setting of 1 side of handle is arranged in 3 side of guider positioning seat
There is guide slide, be slidably connected shin bone registration arm 2 on guide slide, and guide slide passes through positioning screw fixed tibial registration arm 2,
Hook plate 6 is arranged in 2 end of shin bone registration arm, and the angle α between hook plate 6 and shin bone registration arm 2 is 122 degree, the inside both sides of hook plate 6
It is respectively arranged with and captures protrusive board 5, guider positioning seat 3 is tile like structure.
When the utility model is used, conduit 4 is removed from guider positioning seat 3, single hand grip is 1, in arthroscope
Guidance under, the claw structure of shin bone registration arm end is sent into articular cavity, after claw structure contacts posterior cruciate ligament of knee, edge
The dissection posterior cruciate ligament of knee stop out of shape that tracks of posterior cruciate ligament of knee, after claw structure to posterior cruciate ligament of knee stop, with two pieces
Guider positioning seat 3 is fixed in front of shin bone by screw or Kirschner wire, and after fixing-stable, conduit 4 is turned back to guider positioning
Seat 3, Kirschner wire pierces shin bone to posterior cruciate ligament of knee stop from conduit 4, then drills through bone road with the drill bit of suitable size, in case tendon
Or other fixtures pass through, and complete operation, finally carry out the reconstruction operation of posterior cruciate ligament.
