Abstract
The utility model relates to a dislocated acromioclavicular joint micro-motion fixing plate, belonging to the technical field of orthopedic medical apparatuses. The dislocated acromioclavicular joint micro-motion fixing plate is used for restoration and fixation surgeries of a dislocated acromioclavicular joint and consists of a clavicle positioning sheet and an acromion sheet. One to three positioning sleeves are fixed at the front part of the clavicle positioning sheet. Threads are arranged in each positioning sleeve. Acromion sleeves are arranged at the rear part of the acromion sheet. The acromion sleeves are of through holes. The positions of the acromion sleeves correspond to the positions of the positioning sleeves. A connecting rod is arranged in each acromion sleeve. Threads which are matched with the threads in the positioning sleeves are arranged at one end of the connecting rod and a cylindrical rod cap is arranged at the other end of the connecting rod. Since the clavicle positioning sheet and the acromion sheet are connected by using sleeves and micro-motion of 5 to 10 degrees between the side fork of the clavicle positioning sheet and an acromion is allowed, the fixing plate is more compliant with the physiological activities of the acromioclavicular joint; and moreover, since the side fork is inserted into the center of cortices on the upper side and the lower side of the acromion or positioned below the acromion, the fixation strength is high, the implementation of ligament prosthetics is facilitated and the damages to acromioclavicular joint capsules and surrounding ligaments are small.
Description
Technical field
This utility model relates to a kind of fixture for the treatment of acromioclavicular joint dislocation, belongs to the orthopedic medical device technical field.
Background technology
In orthopaedic medical treatment operation, the resetting and fixedly be a kind of operation that needs to be grasped of acromioclavicular joint dislocation.Acromioclavicular joint dislocation mostly is the direct violence damage, is subjected to directly clashing into causing injury as shoulder in vehicle accident.When this position fracture or dislocation, near ligament damage in various degree can causing causes the shoulder joint function obstacle.The operation method of treatment acromioclavicular joint dislocation is a lot, traditional has the Kirschner wire tension band to fix, hook plate is fixed, fixation with steel wire etc.In these methods, the shortcoming of Kirschner wire tension band fixing means is that Kirschner wire is deviate from easily, instability before and after fixing not firm causing; And during application hooks steel plate treatment acromioclavicular joint dislocation, the far-end hook of hook plate is inserted in the below of acromion, when the upper limb abduction, produce under the acromion easily and clash into, and, tend to damage ligament of acromioclavicular joint during taking-up because its plate body profile is unfavorable for the reparation of row ligament of acromioclavicular joint more greatly.The far-end of hook plate is inserted under the acromion, and nothing is additionally fixing, so front and back and activity up and down can take place, and part patient's hook plate even generation are obviously dislocated and lost fixation; Fixedly clavicle far-end and acromial end can increase its fixed fastness simultaneously, but do not meet acromion and there are these physiological activity characteristics of fine motion in the clavicle far-end, preferably the fine motion function can be arranged on the basis that is connected firmly.For this reason, medical worker and patient wish to develop and develop new operating theater instruments and method, so that when the treatment acromioclavicular joint dislocation, reach better surgical effect, can reduce patient's misery and the burden that alleviates economically simultaneously, and can promote the use of at basic hospital.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of physiological activity characteristics that meet acromion and clavicle more, has the fine motion function, can increase simultaneously fixing head and acromion constant intensity, be beneficial to capable ligament repair, avoid taking place acromion bump syndrome, when taking out to capsula articularis acromioclavicularis and around the little Micromovement fixing plate for dislocation of acromioclavicular joint of ligament injury.
The technical scheme that solves the problems of the technologies described above is:
A kind of Micromovement fixing plate for dislocation of acromioclavicular joint, it is by the clavicle spacer, the acromion sheet is formed, the clavicle spacer is rectangle steel disc or titanium plate, plate face y direction is distributed with 2-5 locating hole in plate face upper edge, the acromion sheet is rectangular steel disc or titanium plate, outboard end can be and is fillet or right angle, 1-3 the abutment sleeve that be fixed with in clavicle spacer bottom surface, screw thread is arranged in the abutment sleeve, acromion sheet bottom surface the acromion sleeve arranged, the acromion sleeve is a through hole, its position is corresponding with abutment sleeve, in the acromion sleeve connecting rod is arranged, the diameter of connecting rod is less than the telescopic internal diameter of acromion, and an end of connecting rod has the screw thread that is complementary with the abutment sleeve female thread, and the other end of connecting rod has cylindrical pole cap, pole cap is positioned at the telescopic outer end of acromion, and the diameter of pole cap is greater than the telescopic internal diameter of acromion.
Above-mentioned Micromovement fixing plate for dislocation of acromioclavicular joint has the side fork on clavicle spacer plate face, the side fork is connected the side-lower of clavicle spacer, and is parallel with the longitudinal axis of clavicle spacer, and is gapped between side fork and the acromion sheet.
Above-mentioned Micromovement fixing plate for dislocation of acromioclavicular joint, described clavicle spacer are along the Y-direction both sides bending of plate face, and the crooked radian and the periphery of clavicle are complementary.
Above-mentioned Micromovement fixing plate for dislocation of acromioclavicular joint, there is the crotch of inwardly holding clavicle tightly the both sides of described clavicle spacer.
State Micromovement fixing plate for dislocation of acromioclavicular joint, described acromion sheet is a straight plate or along the X both sides bending of plate face, and 1-3 locating hole arranged on the plate face.
Above-mentioned Micromovement fixing plate for dislocation of acromioclavicular joint, described side fork front end is more sharp-pointed, and its length is less than or equal to the length of acromion sheet.
Adopt the Micromovement fixing plate for dislocation of acromioclavicular joint of this structure, the clavicle spacer adopts telescopic the connection with the acromion sheet during use, and the side fork and the acromion of clavicle spacer have 5 °-10 ° fine motion, more meet the physiological activity characteristics of acromioclavicular joint; Simultaneously, the side fork is inserted into the cortex central authorities of acromion upper and lower sides or is positioned under the acromion, use screw the acromion sheet be fixed on the acromion, have constant intensity big, help carrying out repair of ligament, avoid taking place acromion bump syndrome, to capsula articularis acromioclavicularis and around the little advantage of ligament injury.Patient's post-operative recovery time is short, and healing alleviates the medical burden of patient and society smoothly, and technical operation is easy, is convenient to promote at basic hospital.
