Abstract
The utility model provides a patella fixing skeleton, which is composed of a fixing hook, an adjustable bolt, a fixing device, a locking bolt, a parallel grasping hook, rod connecting bolts and connecting rods; wherein the fixing device is composed of two sleeves with identical structure, a form of a pair of left and right fixing devices is formed, the fixing hook used for clamping the patella is firmly arranged at one end of the fixing device, a thread hole is arranged at the other end of the fixing device, and the locking bolt is arranged in the thread hole. The parallel grasping hook is composed of two separate grasping hooks, the connecting rods are respectively arranged at the position where the two grasping hooks are adjacent to the hook part, connecting rod bolt holes are arranged on the connecting rods on the two grasping hooks, and the rod connecting bolts are arranged in the connecting rod bolt holes. One end of the parallel grasping hook is arranged in the sleeve of the fixing device, and thereby a rod-typed slide way structure in the tube is formed. The patella fixing skeleton has the advantages that the structure is simple, the operation is convenient, the patella fixing skeleton is suitable for all types of skeleton fracture, the positioning of the fractured skeleton is firm and reliable, the fractured skeleton is uneasy to fall off, the injury caused by the operation is relatively small, and aggregating force can be continuously applied to the fracture end during the operation.
Description
Technical field:
This utility model relates to bone injury and recovers assistive device, relates in particular to the patella fixed mount.
Background technology:
Patella fracture is the common articular fracture of orthopaedics in the medical science, but because the powerful pulling force of quadriceps femoris often fixedly brings difficulty to reduction.The pressurization of threading a needle mainly is that pressure is not enough, and in early days in the activity by the active force of quadriceps femoris and articulatio femoropatellaris, easily rotate displacement forward.The arc looper maintains static up and down, fixed position is on the cephalolateral margin of the utmost point up and down, can not be arbitrarily with folded block adjustment and the timely droop of correcting, especially to utmost point avulsion folding, following utmost point comminuted fracture can't be used down, limited its scope of application, Chinese patent 200520086942.2 discloses a kind of patella fixed mount, but distance can not be regulated between two grapples of this fixed mount, so the patient of incompatibility all age group uses.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of easy to operate, fixed patella fixed mount is provided.
Patella fixed mount described in the utility model includes fixture, fixation hook, adjusting bolt, lock(ing) bolt, parallel grapple, connecting rod and connecting-rod bolts and constitutes.Said fixture, form by two identical sleeves of structure, form the form of pair of right and left fixture, be set with at an end of fixture and block the fixation hook that patella is used, on the extending part of the inside 90 degree bendings of two fixation hooks, be provided with screw, in screw, be provided with the fixation hook connecting bolt, two fixation hooks are connected as one; The other end in fixture is provided with screwed hole, is provided with lock(ing) bolt in screwed hole.Said parallel grapple is made up of two independent grapples, position in the close hook portion of said two grapples is provided with connecting rod, connecting rod on two grapples is provided with the connecting rod screw, in the connecting rod screw, be provided with connecting-rod bolts, one end of said parallel grapple is arranged in the sleeve of said fixture, form the slideway structure of rod-type in a kind of pipe, be provided with the adjusting bolt on the top of the other end of said parallel grapple.In use, according to the Patella fracture patient's age, adjust the distance between fixation hook and the parallel grapple, fixation hook is fixed with parallel grapple, so that and patient's patella coupling, then fixation hook is blocked the edge of patella, the rod end with parallel grapple pierces in the sleeve again, makes the other end of parallel grapple block another edge of patella, tighten the adjusting bolt, the patella of fracture is resetted, tighten lock(ing) bolt then, prevent that parallel grapple is loosening.
Patella fixed mount described in the utility model, simple in structure, easy to use, be applicable to all types of Patella fracturies, to the patella location of fracture, fixed, difficult drop-off, Shou Shu wound is little comparatively speaking, does not influence the situation of using the observation of use instrument fracture site at any time in the use, applies cohesion to fracture end sustainably during use, adjust arbitrarily, in time correct droop,, union of fracture and kneed functional exercise can be carried out synchronously to be maintained fixed the constant relatively of power.
Description of drawings:
Accompanying drawing is the structural representation of patella fixed mount described in the utility model.1-fixation hook 2-regulates the parallel grapple 6-of bolt 3-fixture 4-lock(ing) bolt 5-connecting-rod bolts 7-connecting rod
The specific embodiment:
Referring now to accompanying drawing, be described as follows in conjunction with the embodiments: patella fixed mount described in the utility model includes fixation hook 1, adjusting bolt 2, fixture 3, lock(ing) bolt 4, parallel grapple 5, connecting-rod bolts 6 and connecting rod 7 and constitutes.Said fixture 3, form by two identical sleeves of structure, form the form of pair of right and left fixture 3, be set with at an end of said fixture 3 and block the fixation hook 1 that patella is used, the extending part of two fixation hooks, 1 inside 90 degree bendings is provided with screw, in screw, be provided with the fixation hook connecting bolt, two fixation hooks 1 are connected as one.The other end in said fixture 3 is provided with screwed hole, is provided with lock(ing) bolt 4 in screwed hole.Said parallel grapple 5 is made up of two independent grapples, position in the close hook portion of said two grapples is provided with connecting rod 7, connecting rod 7 on two grapples is provided with the connecting rod screw, is provided with connecting-rod bolts 6 in the connecting rod screw, and two grapples are connected as one.One end of parallel grapple 5 is used to grasp patella, and the other end is arranged in the sleeve of said fixture 3, forms the slideway structure of rod-type in a kind of pipe, is provided with on the top of the other end of said parallel grapple 5 and regulates bolt 2.In use, according to the Patella fracture patient's age, adjust the distance between fixation hook 1 and the parallel grapple 5, fixation hook 1 is fixed with parallel grapple 5, so that and patient's patella coupling, then fixation hook 1 is blocked the edge of patella, the rod end with parallel grapple 5 pierces in the sleeve again, makes the other end of parallel grapple 5 block another edge of patella, tighten the adjusting bolt, the patella of fracture is resetted, tighten lock(ing) bolt 4 then, prevent that parallel grapple 5 from becoming flexible.Patella fixed mount described in the utility model, simple in structure, easy to use, be applicable to all types of Patella fracturies, to the patella location of fracture, fixed, difficult drop-off, Shou Shu wound is little comparatively speaking, does not influence the situation of using the observation of use instrument fracture site at any time in the use, applies cohesion to fracture end sustainably during use, adjust arbitrarily, in time correct droop,, union of fracture and kneed functional exercise can be carried out synchronously to be maintained fixed the constant relatively of power.
