Abstract
The utility model discloses door sprig preflex ware and director of usefulness are rebuild to orthopedics ligament, the front end of handle no. 1 is equipped with the preflex head, preflex is overhead to be 2.5mm to having the diameter, is 20mm's blind hole deeply, this blind hole with the door sprig diameter clearance fit, apart from the blind hole the first side of preflex to having the preflex groove, wherein the preflex groove is open slot, the width of open slot is 2.5mm, that an inclined plane and an open slot lower extreme with bottom surface one -tenth 120 forms the shear surface jointly below the preflex groove, the door sprig of usefulness is rebuild to the orthopedics ligament, and the front end of handle no. 2 is equipped with the guiding hole, is equipped with the guide block in the guiding hole, and the centre of guide block is equipped with and a door sprig both sides complex double flute, the guide block is that the two halves assembly is in the same place. Door sprig preflex ware can very conveniently become door type, the door sprig that obtains with the preflex of diameter 2.5mm ke shi needle after the reuse vice is cut off, door sprig director makes the installation of door sprig easy, and disappearance door sprig is crooked, makes in the firm embedding sclerotin of door sprig.
Description
Technical field
This utility model relates to a kind of doornail instrument of orthopaedics ligament reconstructive, and specifically the gate of orthopaedics ligament reconstructive follows closely pre-bending device and guider.
Background technology
Gate is followed closely: outward appearance, as door or staple, often needs to utilize Kirschner wire to make gate nail, and pounded in sclerotin by gate nail, then ligament Suspending fixation gate nailed in knee arthroscope anterior cruciate ligament and posterior cruciate ligament reconstruction art.
The instrument utilizing Kirschner wire to make the use of gate nail for material is core drill, pliers, vice etc., size and form easily occur defective, using pounder and hammer that gate is followed closely when installing gate nail enters in tibia sclerotin, this process often occurs that gate nail is bending, installs difficulty; Surgeon uses instrument pre-bending to make gate nail on operating-table, often occur making gate nail length and pre-bending angle undesirable.
Gate nail, pounding in the process in sclerotin, because sclerotin is hard, often occurs that gate nail is bending, even occurs sclerotin splitting, install difficulty.
More than add the difficulty of operation, extend operating time.
Here gate nail is pre-bent to gate with diameter 2.5mm Kirschner wire.
Summary of the invention
This utility model is in order to quick Fabrication gate can follow closely and be pounded in sclerotin by gate nail fast, and gate nail does not bend, the gate nail pre-bending device of special proposition orthopaedics ligament reconstructive and guider.
The technical solution of the utility model is for this reason, and the gate nail pre-bending device of orthopaedics ligament reconstructive, comprises a handle one, it is characterized in that: the front end of handle one is provided with pre-bending head, pre-bending head is 2.5mm to having diameter, be the blind hole of 20mm deeply, the diametric clearance cooperation of this blind hole and gate nail; At pre-bending head side to having pre-bending groove, wherein pre-curved groove is an open slot, and the width of open slot is 2.5mm.
Further improvement is: be an inclined-plane becoming 120 ° with bottom surface below described pre-curved groove, and open slot lower end forms shear surface jointly.
The gate nail guider of orthopaedics ligament reconstructive, comprises a handle two, it is characterized in that: the front end of handle two is provided with pilot hole, is provided with guide pad in pilot hole, and the centre of guide pad is provided with the double flute coordinated with gate nail both sides.
Further improvement is: described guide pad is that two halves are assembled together.
Beneficial effect:
Diameter 2.5mm Kirschner wire easily can be pre-bent to gate by the gate nail pre-bending device of this utility model orthopaedics ligament reconstructive, then the gate nail obtained after cutting off with vice; The making that gate nail pre-bending device makes gate follow closely is simple, and the gate nail made meets the requirements.
The setting of shear surface ensure that the shearing inclination that gate is followed closely, the lower end that gate is followed closely have guiding point.
The gate nail guider of orthopaedics ligament reconstructive, makes gate follow closely and installs easily, does not occur that gate nail is bending, gate is followed closely and firmly embeds in sclerotin.
Guide pad is that two halves are assembled together, when gate nail just can take out guide pad when hammering into certain size, and convenient further downward nail.
