Description
Technical field
It is a kind of steel plate of tension band for patellar fracture specifically the present invention relates to technical field of medical instruments.
Background technology
Kneecap is the maximum sub- bone of human body, in front of knee joint, with the kneed effect of protection.Pass behind kneecap
Nodal section is relative with femoral bone pulley face.Quadriceps muscle of thigh is attached to kneecap upper limb, and part manadesma in front of kneecap through extending for ligamentum patellae, only
In tibial tubercle.Kneecap plays vital effect in human knee moves, for example, being used as knot in the middle of Quadriceps mechanism
Structure, the pulling force that quadriceps muscle of thigh is produced is transmitted to kneecap tendon by it；Kneecap plays leverage when stretching knee, can effectively increase and stretch knee dress
Put the lever arm of force that axle point is bent and stretched for knee joint；By slip of the kneecap on femoral bone pulley face, a strand four-head can also be cut down
Flesh is to the friction before distal part of femur.
The treatment on patellar fracture generally uses tension band wiring method and hollow screw tension band method in the prior art.
However, there is following defect and deficiency in clinical practice：
Tension band wiring method can not then fix sclerite, if Patellar joint is repaiied for slightly complicated comminuted fracture
Multiple relatively difficult, operating process Kirschner wire position fixes not good, it is necessary to inserting needle repeatedly, so as to aggravate fracture, and postoperative easily draws
Play Kirschner wire to release, cause operative failure；Also there is Kirschner wire backshank residual long, Kirschner wire easily stimulation innings when knee joint is bent and stretched
Portion's skin and cause wound infection, osteomyelitis etc. to influence functional rehabilitation, and steel wire and Kirschner wire there may come a time when cell reaction occur,
Kirschner wire can be caused to loosen and steel wire fracture, or even nonunion, so that knee joint flexion-extension motion is influenceed, or even interior fixed mistake
Lose.
Hollow screw tension band method is that above-mentioned Kirschner wire is replaced into city hollow screw, and steel wire is put from hollow screw
Enter afterwards and pass the tension band to form 8-shaped.This method has the following disadvantages and defect：1. in order to realize that hollow screw longitudinally adds
The effect of pressure, hollow screw needs are parallel to insert, and operation difficulty is big, it is necessary to which experienced operative doctor could be completed；2. it is hollow
The tension band of screw is to be fixed on by steel wire winding before kneecap in intersection " 8 " word, blocking of the steel wire to the cutting of ligament to blood supply
Effect, the healing belt to fracture carrys out bad influence；3. the mechanical environment between hollow screw and 8-shaped winding steel wire is complicated,
It is not easily taken out, and in active procedure, easy steel wire is broken in invagination.
Chinese patent literature CN200320114822.X, applying date 2003-10-20, patent name is：For patellar fracture
The internal fixation device for the treatment of, discloses a kind of internal fixation device for patella fracture, by the fixator that can be matched with kneecap
Main body, body rim locally extend the fastening structure that is bent to form and in main body with for fixator and kneecap to be installed with
The mounting hole that fastener together is engaged is constituted.The utility model can play good replacement and fixation to patellar fracture position
Effect, can play good pressing effect again, and fixed firm reliable.
Above-mentioned patent document is treated to the kneecap of fracture, and patient can be carried out functional training in early stage, be conducive to
The comprehensive early recovery of patient.But the steel plate of tension band good on a kind of taking-up easy to operate, not easy to break, easy, fastness is then
Without corresponding open.
In summary, it is necessary to it is a kind of it is easy to operate, not easy to break, easy take out, the good steel plate of tension band of fastness.And on
This steel plate of tension band yet there are no report.
