Abstract
The invention relates to a knee joint anterior and posterior cruciate ligament femoral tunnel positioner. The positioner comprises a hook body, wherein the hook head of the hook body extends in the knee joint cavity and points to the anterior and posterior cruciate ligament femoral insertion; the long stem of the hook head is upward and above the front of the femur of knee joint and is connected with an arc chute which is arranged laterally; a curved lever which can slide relatively to the arc chute is embedded in the arc chute; and the movable end of the curved lever is provided with a drill stem guide sleeve which directly points to the tip of the ligament hook head. By adopting the positioner of the invention, the problem that the previous arthroscope can perform observation only through the lateral approach and the visual blind area is caused, can be solved; and the reconstruction of femoral tunnel can be better performed from the physical point of the ligament, thus the reconstruction of femoral tunnel in clinic has higher repeatability and operability, the accuracy degree of operations is greatly increased, the operating time is reduced, and the positioner has great use value and wide market space.
Description
Technical field
The present invention relates to medical instruments field, relate in particular the forward and backward ligamentaum cruciatum femur of a kind of knee joint side tunnel locator.
Background technology
One, front friendship, back vent ligament physiological function
1, anterior cruciate ligament (anterior cruciate ligament) and posterior cruciate ligament (posterior cruciate ligament) are to keep knee Stability and guide knee joint to finish the important feature of its function.
2, the forward and backward ligamentaum cruciatum damage of annual knee joint patient is a lot.
3, its damage heavy damage knee Stability, but the damage of other important feature of secondary knee joint knee joint.
4, can not self-healing after the ligamentaum cruciatum damage, operative reconstruction must be passed through and kneed stability could be recovered.
Two, in the present forward and backward Cruciate ligament reconstruction postoperative, the chronic frustration rate is very high, its former because:
1, tibial side stop location mistake.
2, the femur tunnel moves towards mistake.
Three, present kneed femur side localization method has two kinds:
1, through the tibial tunnel location.
2, through medial approach location before the knee joint.
Four, the correct femur side tunnel of setting up should satisfy following requirement
1, should continue normal ligament direction of travel, should as close as possible femur major axis at femur sagittal plane and coronalplane.
2, the outlet of the other end in tunnel should be outside the femoral lateral condyle articular surface.
Five, have at present the localizer shortcoming now
Only can locate by intraarticular during 1, owing to the location, the foundation in anterior cruciate ligament femur stop location and femur tunnel is affected by tibial tunnel trend and operative approach seriously, and femur tunnel direction is substantially unadjustable, is difficult to reach the reconstruction requirement in tunnel.
2, perform an operation and depend on patient's experience, can say that everyone, each tunnel that rebuilds may be different, do not have repeatability, persuasion property is poor.
3 comply with the wrong femur tunnel of setting up causes " ligament-bone " interfacial stress large, finally causes the ligament reconstruction failure.
Summary of the invention
The object of the present invention is to provide the forward and backward ligamentaum cruciatum femur of a kind of knee joint side tunnel locator, this localizer has not only solved the past arthroscope can only be from the vision dead zone problem of lateral approach observation post generation; And can better rebuild with the physiological angle of ligament, have higher repeatability and easy operating so that rebuild clinically femur side tunnel, greatly improve the levels of precision of operation, reduced operating time, had great use value and the wide market space.
Technical program of the present invention lies in: the forward and backward ligamentaum cruciatum femur of a kind of knee joint side tunnel locator, comprise the crotch body, the gib head of described crotch body stretches into knee joint cavity and points to forward and backward ligamentaum cruciatum femur side stop, the long handle of described gib head up and be positioned at knee joint femur front side top, described long handle is connected with the arc chute of a horizontally set, edge is provided with the relatively bow of arc chute slippage in the described arc chute, and described bow movable end is equipped with a drilling rod guide pin bushing that directs at the gib head end.
Be provided with the angle index line on the described bow.
Described arc chute is near being provided with a location bolt on drilling rod guide pin bushing one end.
Described drilling rod guide pin bushing is a hollow guiding bar.
Can be provided with a metal tape tooth annulus on the described gib head end, described drilling rod guide pin bushing directs at the center of circle of this metal tape tooth annulus.
Be provided with the tip of an oblique outer top on the described gib head end.
No matter be that tip or metal tape tooth annulus all are convenient location ligament femur side stop usefulness, both designs can be used.
All be the patient's use to forward and backward due to cruciate ligament in the middle of the operation, their ligament has not had, or only is left stump.Location in the knee joint relies on the tip of crotch body or position or the scope that metal tape tooth annulus is determined the ligament stop; Only the method for location is different, and locating with the tip of crotch body is that the border that the ligament stop is caught at the tip makes ancon (gib head end) be positioned at the center of ligament stop; And metal tape tooth annulus is the probable ranges that circle is lived the ligament stop, makes the center of circle of metal tape tooth annulus be positioned at the center of ligament stop.
It is worth mentioning that, localizer of the present invention not only can use at rebuilding anterior cruciate ligament, also can be applied in and rebuild on the posterior cruciate ligament, described localizer for the reconstruction anterior cruciate ligament becomes mirror image with the localizer of rebuilding posterior cruciate ligament.More what deserves to be explained is, locator application of the present invention is equally applicable to rebuild the posterior cruciate ligament of right knee joint in the anterior cruciate ligament of left knee joint, in like manner as can be known, locator application of the present invention is equally applicable to rebuild the anterior cruciate ligament of right knee joint in the posterior cruciate ligament of left knee joint.In sum, only need the localizer of the present invention of a pair of one-tenth mirror image symmetry, can satisfy the needs of two forward and backward ligamentaum cruciatums of knee joint femur about reparation.
The invention has the advantages that: the one, adopted by the export-oriented intraarticular in joint and undertaken with reference to the design concept of locating, the design of reference outside the joint so that free in the operation process, regulate the direction set up femur side tunnel easily, make the osseous tunnel direction become possibility near ligamentaum cruciatum physiology direction of travel; Solve original ligament and rebuild the problem that apparatus can't change femur tunnel direction of travel, can better rebuild with the physiological angle of ligament, reduced " ligament-bone " interfacial stress; The 2nd, have higher repeatability and easy operating so that rebuild clinically femur side tunnel; The 3rd, clearly the gib head end of this localizer from the homonymy operative approach of location stop (metal tape tooth annulus or gib head end) (when both having rebuild ACL femur tunnel from knee joint outside operative approach location; And when rebuilding PCL femur tunnel from the inboard operative approach of knee joint location) enter articular cavity, arthroscope can better be observed intraarticular location situation from inboard operative approach, has solved the vision dead zone problem that arthroscope lateral approach observation post previously produces.
