Technical field
The present invention relates to medical instruments field, is specially a kind of knee joint front cruciate ligament tibia end positioner.
Background technology
In sports medical science disease, anterior cruciate ligament of knee joint fracture is relatively conventional, and the fracture of anterior cruciate ligament can cause
The damage of its hetero-organization such as articular cartilage meniscus, anterior cruciate ligament of knee joint occurs in kneed shakiness, treatment not in time
Reconstruction be the important research topic of medicine in field of sports medicine all the time.Anterior cruciate ligament of knee joint rebuilds minimally invasive hand under arthroscope
Art is a Minimally Invasive Surgery, and this method difficulty is larger and operation is fine, it is necessary to dedicated apparatus, but relative to traditional open
Operation, the integrality of capsula articularis genus can be kept in ligament reconstructive, have wound small, recover fast, and postoperative pain is light, complication hair
Raw rate is low and the advantages that the hospital stays is short, and a kind of Special surgical instrument used in above-mentioned operation is that tibial insertion of anterior cruciate ligament is determined
Position device.During operation, arthroscope, douche can injection system are inserted in kneed articular cavity first, then under Arthroscopy,
The position that the anterior cruciate ligament that the positioning protrusion of locator front end is placed on the inside of eminentia intercondyloidea is adhered to, guide rod front end is abutted against
On shin bone, guide pin is penetrated in the guide slide of guide rod, bone road is established on shin bone along the direction of guide slide, is determined
The introduction channel position of ligament tibia end ligament, during guide pin penetrates tibial plateau, above-mentioned shin bone guider use, due to intercondylar
Swell (anterior cruciate ligament original attachment position) and adhere to substantial amounts of soft tissue, it is difficult to accurately find desired position point；In addition this
Place is located at articular cavity middle section, and shin bone guider is positioned at this, has further blocked light and the visual field of arthroscope, and technology will
Ask high, thus easily lead to the error of anterior cruciate ligament attachment point (lower dead center) on tibial plateau determined in operation
Greatly, therapeutic effect is poor, cannot complete stop anatomical position reconstruction, or even occur function of joint be limited, must revision procedure, overhaul
Rate is high.Through State Patent Office's CD query and search, number of patent application：2015110116653, a kind of eccentric positioning shin bone is oriented to
Device.Although it reduces the revision rate of revision procedure.It is of high cost but it is complicated, different sizes are needed replacing in operation
Registration arm, the ligament of selection is measured in operation certain error according to the diameter for soaking degree measurement, complicated, be not easy
Grasp its operation order.
The content of the invention
It is of low cost the object of the present invention is to provide a kind of simple in structure, machine driving, easy for operation, quick side
Just knee joint front cruciate ligament tibia end positioner.The object of the present invention is achieved like this：Intersect before a kind of knee joint
