And guide pin." C-arm " perspective again: fracture reduction is good to line, and inside-fixture position is good.Check dressing apparatus, close
Close otch and wrap up.
Beneficial effect:
One, safety: drawn cable through patellar ligament, patellar ligament and retinaculum patellae by guide pin, will not damage patella and surrounding
Tissue.The head of a nail fixed cable of T post side fixing hole or end fixing hole is fixing reliable, will not damage cable.
Two, effectiveness: having multiple cable fixed system on the market at present, clinical practice is extensive.Native system is at existing inner fixer
Improve on the basis of tool, it is adaptable to human body shaft fracture, the patient, especially comminuted patellar such as Patella fracture.The design of guide pin
Be conducive to alleviating operation wound, facilitate operation technique.The head of a nail of T post is designed with effective maintenance of beneficially cable strain, it is to avoid damage
Hinder cable.Thus, alleviate.The operation wounds such as Patella fracture, reduce operating time.Be conducive to patient's early recovery.
The utility model has the advantage of:
1, the guide pin design that this utility model provides.Guide pin near-end round needle post is flexible, can pre-bending, according to the shape of fixing fracture
Pre-bending, in order to pin peak runs through.Far-end is provided with the unimodal pin in double angles and is designed with and is beneficial to run through ligament.
2, the T post design that this utility model provides.T post one end is provided with end fixing hole, and side is provided with side fixing hole, cable hole.
Be conducive to head of a nail fixed cable.End fixing hole is fixed with the selection that side fixing hole is designed with the beneficially head of a nail and cable.Setting of T post
Meter also helps the fixing of Y cable.
3, the head of a nail design that this utility model provides.The head of a nail be designed with the pressure beneficially controlling fixed cable, it is to avoid damage cable.
The U-shaped fixture block of head of a nail far-end is designed with and the most at utmost decomposes compressive stress between the head of a nail and cable, adds the fixing intensity of cable.Nail
