Description
Technical field
This utility model relates to the medical operation apparatus, and especially a kind of posterior cruciate ligament of knee joint is rebuild localizer.
Background technology
At present, knee joint injury is increasing, and wherein the ligamentaum cruciatum damage has accounted for very big ratio.Increasingly mature along with the arthrocsopic surgery technology, ligament reconstruction is selected in the ligamentaum cruciatum damage usually.The posterior cruciate ligament Reconstruction is bigger than the reconstruction of anterior cruciate ligament difficulty, and risk is bigger.Because there are important nerve, blood vessel in the knee joint rear,, even cause amputation in case damage will cause serious consequence.And the posterior cruciate ligament that uses is now rebuild the tibia localizer and is had certain defective, as can not accurately measuring the length of tibial tunnel, and problem such as guidance quality is poor slightly.This will certainly increase the risk of operation.So need on the basis of existing localizer in addition improvement design badly, with increase its practical with and safety.
Summary of the invention
The purpose of this utility model is to provide a kind of posterior cruciate ligament of knee joint to rebuild localizer, to satisfy the needs of arthroscope Wicresoft ligament reconstruction operations treatment.
The technical solution of the utility model is:
A kind of posterior cruciate ligament of knee joint is rebuild localizer, comprises handle, and handle one end is provided with the guider positioning seat of tubular, is provided with guider in the guider positioning seat; Handle is provided with arch locating slot and setscrew nut, be provided with the tibia positioning handle of hook solid in the arch locating slot, tibia positioning handle end is provided with the tibia location hook, be arranged with the guide pin positioning pipe in the described guider, the front end of the end of guider and guide pin positioning pipe is respectively equipped with graduated scale, the position of corresponding its graduated scale is provided with screw on the guide pin positioning pipe, is provided with stop screw in this screw.
The tibia location hook rear of described tibia positioning handle is provided with and struts handle.
Described guider positioning seat is provided with the guider dog screw.
The beneficial effects of the utility model are:
This utility model is rational in infrastructure, and is easy to use.Increased scale on the guider, can in operative process, measure the degree of depth that guide pin need enter accurately, can prevent effectively that guide pin from entering long and damage rear important vessel, nerve.
Prolong part after guider has increased, promptly the guide pin positioning pipe makes guide-localization more accurate, can make guide pin more accurately get out from making pin mark in advance.In addition, the guide pin positioning pipe has also designed scale and stop screw, can effectively control the degree of depth that enters.
There are important nerve, blood vessel in the knee joint rear, and the tibia location hook rear of tibia positioning handle is provided with and struts handle, can strut knee joint rear joint capsule, increases the working place of chamber between posterior joint, thereby has avoided damage neural, blood vessel effectively.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
A kind of posterior cruciate ligament of knee joint is rebuild localizer, comprises handle 1, and handle 1 one ends are provided with the guider positioning seat 10 of tubular, are provided with guider 3 in the guider positioning seat 10; Handle 1 is provided with arch locating slot 11 and setscrew nut 12, is provided with the tibia positioning handle 2 of hook solid in the locating slot 11, tibia positioning handle 2 can be in locating slot 11 sliding extension, and can be fixing by setscrew nut 12.
Tibia positioning handle 2 ends are provided with tibia location hook 20, be arranged with guide pin positioning pipe 4 in the guider 3, the front end of the end of guider 3 and guide pin positioning pipe 4 is respectively equipped with graduated scale, and the position of corresponding its graduated scale is provided with screw on the guide pin positioning pipe 4, is provided with stop screw 40 in this screw.
Tibia location hook 20 rears of tibia positioning handle 2 are provided with and strut handle 21, can strut knee joint rear joint capsule, increase the working place of chamber between posterior joint, thereby have avoided damage neural, blood vessel effectively.
During use, the angle of tibial tunnel is at first as required regulated the collapsing length of tibia positioning handle 2 in locating slot 11, and screwed in place nut 12 is fixing;
Then, guider 3 is goed deep into assigned address in the guider positioning seat 10, guider 3 forward tip are conflicted on patient's tibia, and tighten guider dog screw 13, read the scale on the guider 3;
Then, stop screw 40 is tightened on the guide pin positioning pipe 4 in the screw on the scale identical with the scale read on the guider 3;
At last, guide pin is goed deep in the guide pin positioning pipe 4, the electric drill head of fixation guide pin is tight against guide pin positioning pipe 4 ends, and guide pin positioning pipe 4 is goed deep in the guider 3, and under the effect of stop screw 40, guide pin can directly accurately get out in the precalculated position.
