Description
Technical field
The utility model relates to orthopedic medical device, specifically a kind of neck of femur side position drilling director.
Background technology
The clinical middle fractured near end of thighbone internal fixation operation technology of medical treatment has been widely used in clinical, no matter is that the interior technique for fixing of marrow or the outer steel plate technique for fixing of marrow all need lead exactly and hole, and makes boring and hold-down screw all in neck of femur. In the time of operation, normotopia can be looked at lower observation bore position straight, and the direction assurance of side position boring is the difficult point of this surgical procedure. Drilling director in existing operation technique apparatus does not have special location, neck of femur side position sighting device, when operation technique, according to the X-ray examination of operator's experience and neck of femur as boring with insert the foundation of screw, error is larger, not only increase medical worker and patient's x-ray radiation, also extended operating time, and neck of femur has been caused to certain damage. The first pin in the patented technology that oneself is disclosed 2011100758148, name is called Special drilling locator for femoral neck is with the horizontal spacing of the second pilot pin by the mobile adjusting of the second pilot pin, and the position of drill bushing and the spacing of pilot pin are fixed; The problem that this patented technology exists is that the distance up and down between pilot pin and drill bushing can not regulate arbitrarily according to patient's femur size, the accuracy of impact location, causes holing unsuccessfully.
Summary of the invention
Object of the present invention technical problem to be solved is to provide a kind of neck of femur side position drilling director, it can solve the deficiency that prior art exists, described pilot pin and boring cylinder regulate arbitrarily as required, depart from carrying out neck of femur side position when operation boring preventing.
The purpose of this utility model is achieved through the following technical solutions: neck of femur side position drilling director, comprise pilot pin and boring cylinder, in first sleeve of the first pilot pin through clamping device outside, clamping device middle part is arc, one end, top of arc clamping device is boss, T-slot is offered in corresponding other end lateral attitude, the degree of depth of T-slot and the medial surface of boss are in a plane, and offer threaded screw in boss inner side, T shape boss on the movable boss matching with T-slot inserts in T-slot, the perforation screw being provided with in activity boss side surfaces, screw connects screw through movable boss and enters corresponding boss screw internal thread connection, the second sleeve is installed in outside, movable boss middle part, the second sleeve is parallel with the first sleeve is positioned at two boss both sides, in the second sleeve, pass the second pilot pin, described arc clamping device lower end is provided with the first screw and the second screw, the first screw is corresponding with the screw of longitudinal fixed bar upper end, and connect by screw flight, longitudinally multiple the first circular holes and the second circular hole are offered in fixed bar lower end, and the first boring cylinder and the second boring cylinder are respectively through the first circular hole and the second circular hole. the first sleeve and boss, the second sleeve and movable boss are with bolts. arc clamping device be shaped as L shaped structure. arc clamping device and the longitudinally shape of cross section of fixed bar are rectangle. the first boring cylinder and the second boring cylinder respectively with the first circular hole and the second circular hole for being flexibly connected. angle between the first sleeve and boss, the second sleeve and movable boss horizontal plane is 45 °.
The utility model has the advantage of: described pilot pin and boring cylinder regulate arbitrarily as required, depart from carrying out neck of femur side position when operation boring preventing. because arcuate guide fixed bar is parallel with the sleeve direction on clamping device, make the front and back of 2 fixed insertion necks of femur that a pin can be parallel. when the screw of tightening on clamping device, 2 pilot pins can firm grip be lived neck of femur. because arcuate guide fixed bar and straight shape fixed guide fixed pole are connected and fixed with holding screw, make to point to accurately by the sleeve direction of arcuate guide fixed bar lower through-hole the centre position of 2 pilot pins, guarantee that boring and the screw being screwed into can not deflect away from from side coil. described arc clamping device is " L " shape structure, one end, top of arc clamping device is made as boss, T-slot is offered in corresponding other end lateral attitude, and offer threaded screw in boss inner side, T shape boss on the movable boss matching with T-slot inserts in T-slot, the perforation screw being provided with in activity boss side surfaces, screw connects screw through movable boss and enters corresponding boss screw internal thread connection, the second sleeve is installed in outside, movable boss middle part, the second sleeve is parallel with the first sleeve is positioned at two boss both sides, in the second sleeve, pass the second pilot pin, described sleeve and boss also can be with bolts, facilitate regulating sleeve angle.
