Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to coronoid process fracture locating guider under a kind of surgery elbow arthroscopy.
Background technology
Coronoid process fracture is one of common illness of elbow joint.Because this kind of fracture involves joint, as displacement fracture is comparatively large, usually need operative reduction internal fixtion to recover joint contraposition.Traditionally, need to do large otch during coronoid process fracture operation, destroy large to elbow joint surrounding tissue, post-operative recovery is slower.As coronoid process bone block is comparatively large, can only row cutting operation, and for the less coronoid process fracture of bone block, can under elbow arthroscopy monitor, intersect fixing bone block with Kirschner wire.Elbow arthroscopy belongs to Minimally Invasive Surgery mode, and advantage destroys little to elbow joint surrounding soft tissue, and postoperative function recovers fast.But under arthroscope, operation operates different from incision, and the latter, by the somesthetic sensibility perception Kirschner wire direction of patient, makes it pass through fracture face, and the former is then difficult to accomplish this point.The narrow space of elbow joint own, peripheral nerve, blood vessel distance is near, and conventional knee joint guider cannot be applied.Therefore, researching and developing coronoid process fracture locating guider under a kind of elbow arthroscopy is the task that the current urgent need in this area completes.
Summary of the invention
The purpose of this utility model be to provide a kind of easy to use, structure simple, lead surgery elbow arthroscopy accurate, safe and practical under coronoid process fracture locating guider.
In order to achieve the above object, this utility model adopts the technical scheme of following structure: coronoid process fracture locating guider under a kind of surgery elbow arthroscopy, by arc sliding ring, Kirschner wire sleeve pipe, locating piece, handwheel trip bolt, hands handle, cross hold-down screw, positioning needle sleeve pipe, sliding shoe and positioning needle composition, be characterized in: flat cube shaped locating piece level is to the protruding connecting handle of side, opposite side cantilever, longitudinally through hole is had in the middle part of it, be slidably matched in through hole and insert Kirschner wire sleeve pipe, Kirschner wire casing centerline and handle cross central line are at an angle of 90, and hold out against Kirschner wire sleeve pipe by the handwheel trip bolt screw-in locating piece above handle, on handle, arc sliding ring one end fixed by cross hold-down screw, the arc sliding ring other end is slidably matched in longitudinal groove inserting square sliding shoe, square sliding shoe is laterally provided with through hole, be slidably matched in through hole and insert positioning needle sleeve pipe, and held out against by the handwheel trip bolt screw-in sliding shoe on square sliding shoe top, in positioning needle sleeve pipe, tight fit inserts positioning needle, and positioning needle one end is semicircular hook, and bill is upwards vertical corresponding with Kirschner wire casing centerline.
Kirschner wire sleeve pipe outer ring surface described above is carved with horizontal slide-rule dial value, and scale value is 1mm.
Arc sliding ring radian described above is 110 °, and cambered surface is carved with angle index, and minimum scale value is 1 °.
Kirschner wire sleeve outer 6.4mm, internal diameter 2.2mm described above.
Positioning needle diameter 2.5mm described above is upwards gradually thin along semicircle bill.
Operation principle of the present utility model is, be expert at coronoid process Fracture internal fixaiion under arthroscope time, first positioning needle is inserted in positioning needle sleeve pipe from straight end tight fit, positioning needle other end semicircle hook-type needle point inserts and inserts joint from elbow joint medial approach, semicircle needle point structure can prevent elbow joint front significant points impaired, after inserting joint, needle point place is propped up fracture face, then slide outward at positioning needle sleeve pipe and be inserted in sliding shoe, be slidably connected in groove on sliding shoe arc sliding ring, fastening with handwheel trip bolt in desired location, Kirschner wire cannula slide is inserted through the longitudinal hole of locating piece, regulate the position of sliding shoe on arc sliding ring, make the centrage of Kirschner wire sleeve pipe vertical corresponding with positioning needle semicircle crochet hook, with the fastening Kirschner wire sleeve pipe of handwheel trip bolt, then Kirschner wire is inserted Kirschner wire casing tube internal hole, vertically Kirschner wire is squeezed into fracture face, because the arc sliding ring with positioning needle is fixedly connected with handle and locating piece, form rigid unitary, and by angle and the distance of the Kirschner wire sleeve pipe that is free to slide and sliding shoe adjustment Kirschner wire sleeve pipe and positioning needle bill, and can lock at an arbitrary position, positioning needle needle point is made all to be positioned on the vertical center line of Kirschner wire sleeve pipe, ensure that Kirschner wire vertically passes from fracture face, facilitate next step fixing sclerite, this utility model can squeeze into diameter 2.0mm and following Kirschner wire.
This utility model uses under total joint mirror, elbow arthroscopy is coordinated to carry out coronoid process fracture fixation, during use, only need conventional observation or the operation approach of elbow joint, and the minimal incision * threaded a needle in elbow joint rear, do not need additionally to carry out operative incision and carry out Arthroscopic portals, reduce operation wound, accurate location coronoid process fracture face also makes Kirschner wire accurately wear to fracture face, easy to use, structure is simple, accuracy is high, reaches goal of the invention.
