Description

The steel plate inner fixer

Technical field

This utility model belongs to medical instruments field, relates to a kind of steel plate inner fixer that is used for the treatment of as orthopaedics special uses such as Patella fracture, acromioclavicular joint dislocation, olecranal fractures.

Background technology

When treating Patella fracture, acromioclavicular joint dislocation, olecranal fracture etc. at present clinically, generally adopt tension band wire, Kirschner wire or the memory golden patella of living inside-fixture such as to grab.When using these several inside-fixtures fixedly during fracture site, the fixing operation more complicated, operating difficulty is bigger, and whole surgery process operation is more.And after fracture site healing, also need in patient's body, to take out inside-fixture again, because when getting inside-fixture such as tension band wire, Kirschner wire, operating difficulty is little unlike operation fixedly the time, also needs incision successively, takes out Kirschner wire, tension band wire etc. successively; When getting the memorial alloy patella claw, not only operative incision is the same fixedly the time with operation, also will be ready to ice cube in advance, and the freezing effect of ice cube once is difficult to reach, and need carry out repeatedly and could grab freezing softening taking-up to the memorial alloy patella.So complexity, loaded down with trivial details when taking out inside-fixture is brought bigger misery to the patient.

The utility model content

At the deficiencies in the prior art, it is a kind of when being used for the treatment of Patella fracture, acromioclavicular joint dislocation, olecranal fracture etc. that the purpose of this utility model will provide exactly, and operation is simple, fixation, taking-up simply are easy to the steel plate inner fixer.

For achieving the above object, a kind of steel plate inner fixer of this utility model, this steel plate inner fixer is a claw hook shape, comprises two identical arcual steel plates and at least one screw, an end of these two steel plates has claw hook respectively, the other end interconnects; Wherein, angle between the axis of two steel plates is the 0-30 degree, distance between the starting point place of starting point to two claw hook of the connecting place of two steel plates is 2-10 centimetre, the distance of two claw hooks from the turning point of radian steel plate to free end points is 2-8 centimetre, the free-ended direction of two claw hooks of two steel plates is identical with the arcual center of described steel plate, be provided with in the junction of two steel plates and have a through hole at least, the quantity of described screw is identical with the quantity of described through hole, and screw and hole size are complementary.

Further, described through hole and screw are one.

Further, described through hole and screw are two.

Further, described through hole and screw are four; Angle between the axis of described two steel plates is 0 degree, and described claw hook is a claws of a hawk shape.

Compared with prior art, this utility model steel plate inner fixer, be to design according to topography form, physiological feature and the fracture of patient's fracture, the type of dislocation, thereby, use simple to operate, the fixation of steel plate inner fixer during operation, and also very simple when taking out this inner fixer, not only can reduce operating difficulty, shorten operating time, and alleviated patient's misery, and reduced medical expense, use manpower and material resources sparingly.

The specific embodiment

This utility model steel plate inner fixer is that topography form, physiological feature and fracture, the dislocation type according to fracture to be treated designs.

Shown in Fig. 1-2, this steel plate inner fixer is a claw hook shape, form by two identical curved plates 1 (2) and screw 7, one end of two curved plates 1, steel plate 2 interconnects, form fixed block 3, fixed block 3 is provided with the through hole 4 that has female thread, through hole 4 is complementary with screw 7, the other end of steel plate 1 and steel plate 2 has identical claw hook 5 and claw hook 6 respectively, the free end of two claw hooks 5 and claw hook 6 all points to the arcual center of two steel plates 1 and steel plate 2, has angle 8 between two steel plates 1 (2).

During operation, hook patient's fracture, the short end of dislocation and far and near two ends, acromion, medial and lateral malleolus far-end or the olecroanon near-end position of patella respectively with claw hook 5 (6), be placed in the long end of fracture, dislocation with fixed block 3, after resetting the affected part well, screw 7 is tightened to the skeleton the inside from through hole 4 fix, promptly achieve the goal.

Among Fig. 3-4, steel plate inner fixer and above-mentioned steel plate inner fixer are basic identical, and its difference is that fixed block 3 is provided with two and has through hole 4 (4 ') and be equipped with two screws 7 (7 ') that are complementary with through hole 4 (4 ').

Among Fig. 5-6, the steel plate inner fixer is made up of fixed block 3 and two claw hooks that combine 5, and promptly the angle between the axis of two claw hooks 8 is 0 degree, and claw hook 5 is claws of a hawk shape, is provided with four through holes 4 on fixed block 3, has four screws 7 that are complementary with through hole 4.

Equally, according to actual needs, more through hole 4 can also be set on fixed block 3, and be equipped with the screw 7 of respective numbers, and single hole, diplopore and porous claw type steel plate inner fixer are in use, equally operate with above-mentioned principle.

Actual needs according to patient's different parts, angle 8 between two steel plates 1 (2) of claw type steel plate inner fixer is that the distance between the starting point place of starting point to two claw hook 5 (6) of connecting place of 0 degree, 15 degree, 20 degree, 30 degree, two steel plates 1 (2) is 2-10 centimetre, and the length of two claw hooks 5 (6) is that the radian (natural radian) of 2-8 centimetre, two steel plates 1 (2) is decided according to each position.For example: during acromioclavicular joint dislocation, the angle 8 between two steel plates 1 (2) is that the distance between the starting point place of starting point to two claw hook 5 (6) of connecting place of 15 degree, two steel plates 1 (2) is that 2 centimetres, the length of two claw hooks 5 (6) are 2 centimetres.During Patella fracture, the angle 8 between two steel plates 1 (2) is that the distance between the starting point place of starting point to two claw hook 5 (6) of connecting place of 20 degree or 30 degree, two steel plates 1 (2) is that 4 centimetres, the length of two claw hooks 5 (6) are 4 centimetres.During fracture of medial malleolus, the angle 8 between two steel plates 1 (2) is that the distance between the starting point place of starting point to two claw hook 5 (6) of connecting place of 15 degree, two steel plates 1 (2) is that 8 centimetres, the length of two claw hooks 5 (6) are 5 centimetres.During olecranal fracture, the angle 8 between two steel plates 1 (2) is that the distance between the starting point place of starting point to two claw hook 5 (6) of connecting place of 0 degree, two steel plates 1 (2) is 10 centimetres, and the length of the claw hook 5 (6) that combines is 8 centimetres.

When needs take out the steel plate inner fixer, the fixed qty of employed screw 7 is cut one or several little otch in the bearing of screw 7 when only needing according to operation, just can take out hold-down screw 7, and then, take advantage of a situation and extract the steel plate inner fixer and get final product at little otch of fixed block 3 one end-grain cutting.
