Abstract
The utility model provides a clavicle far-end hook-shaped steel plate and relates to the technical field of medical instruments. The clavicle far-end hook-shaped steel plate comprises a steel plate body. One end of the steel plate body is bended and of a hook shape, so that a hook body connecting portion is formed. The bending radian of the hook body connecting portion is 100-120 degrees. The middle of the steel plate body is a body portion. The other end of the steel plate body is a handle portion. 6-8 threaded holes and 7-9 kirschner wire holes are formed in the body portion. 2-5 dual-purpose type threaded holes are formed in the handle portion. Each kirschner wire hole is formed beside one dual-purpose type threaded hole. The clavicle far-end hook-shaped steel plate integrates the advantages of a clavicle hook steel plate and the advantages of a clavicle extremitas acromialis steel plate and can be regarded as a perfect combination of the clavicle hook steel plate and the clavicle extremitas acromialis steel plate.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of clavicle far-end hook-plate.
Background technology
Acromioclavicular joint has very important significance to upper limb kinetics.It provides the range of activity of 60 degree in upper limb stretch 180 degree activities together with sternoclavicular joint, and participate in the anteflexion of shoulder joint with after stretch motion.So people are to the treatment pay attention to day by day of injury of acromioclavicular joint.Tossy is divided into 3 types with acromioclavicular joint dislocation: (1) TossyI type: acromioclavicular ligament not exclusively ruptures, and coracoclavicular ligament is complete, and only showing as clavicle on x-ray has slight displacement; (2) TossyII type: acromioclavicular ligament ruptures fully, the coracoclavicular ligament tension injury, and on the stress x-ray, half of Lateral clavicular diameter upwarps the outstanding shoulder that surpasses; (3) TossyIII type: acromioclavicular ligament and coracoclavicular ligament rupture fully, piano key sample body can occur, and x-ray shows that the clavicle far-end is shifted fully.For I type and the dislocation of II type, present many expectant treatments.But not good enough because of the rear outer fixedly difficulty curative effect that resets to the dislocation of III type, tend to operative treatment more.Previously make between tension band wiring, clavicle processus coracoideus screw internal fixation operation etc. more.The art formula is various, and curative effect is unreliable, and all has complication in various degree, as interior fixedly fracture, withdraw from, dissociate, acromioclavicular joint pain, stiff, dislocate again, traumatic arthritis etc.
Clavicle far-end and acromioclavicular joint topography are comparatively complicated.Acromioclavicular joint participates in again the movable maximum shoulder joint activity of whole body.Cause the coracoclavicular ligament fracture after fracture or dislocation, its near-end is shifted upward because of trapezius muscle and the sternocleidomastoid muscle tractive that makes progress, coracobrachialis, biceps brachii m. and pectoralis minor are attached to processus coracoideus, with the downward tractive displacement of shoulder fractures far-end, so not only can strengthen the separation of fracture end and the dislocation of acromioclavicular joint, and can cause processus coracoideus to be shifted down forward and oppress its nervus vasculairs of walking downwards.General expectant treatment fracture end and dislocation are easier to reset, but fix the misery that increases patient for a long time, affect function of joint and are difficult to keep to reset, and the malreduction complication is arranged.Therefore, distal clavicle fracture and acromioclavicular joint dislocation also need operative treatment, make fracture obtain anatomical reduction, rebuild coracoclavicular ligament, recover the function of acromioclavicular joint and shoulder joint.
For acromioclavicular joint dislocation and distal clavicle fracture, clavicular hook plate is a kind of internal fixation device comparatively commonly used.Present clavicular hook plate is structurally comparatively single, and it is also not too convenient to install.
The utility model content
It is a kind of simple in structure and the screw selectable range is wide, easy installation and reliable clavicle far-end hook-plate that technical problem to be solved in the utility model is to provide.
Technical problem to be solved in the utility model realizes by the following technical solutions:
a kind of clavicle far-end hook-plate, comprise a steel plate body, one end of described steel plate body bends to hook-shaped, form the coupler body convergence part, the crooked radian of described coupler body convergence part is the 100-120 degree, generally be designed to 110 degree left and right, hook bent intermediate degree is also generally 110 degree left and right, described steel plate body middle part is body, the other end of described steel plate body is the shank of strip, described body is provided with 6-8 piece of screw, be generally 6 holes, wherein one piece is dual-purpose type, have and lift, pressurization, other 5 pieces is locking-typed screw, diameter is generally 2.7mm or 2.5mm or 3.5mm, selectable range is wide, also be furnished with 7-9 piece of Kirschner wire hole at body, be generally 7 holes, the diameter in Kirschner wire hole is 1.5mm or 2.0mm, have temporary fixed and sew and mend fixation, every piece of dual-purpose type screw side of shank is furnished with one piece, Kirschner wire hole, can play temporary fixed effect, described shank is provided with 2-5 piece of dual-purpose type screw, and the plain edition bore dia is HA3.5mm or HB4.0mm.
The beneficial effects of the utility model are:
1. this utility model is simple in structure, and is easy to use and reliable, practical;
2. dissect design, substantially do not need plasticity, being particularly useful for clavicle comminuted fractures of distal or body has dislocation person;
3. the common feature that has clavicular hook plate and extremitas acromialis claviculae steel plate, can be considered perfect adaptation body both.
