Description
Technical field
The present invention is to be applied to clinical orthopaedics, the cable of a kind of tension band fixation of fracturing, and belongs to medical equipment.It is to apply to human body
Shaft fracture, patellar fracture etc. need the internal fixation apparatus that tension force is fixing.The application of this equipment, is i.e. conducive to alleviating operation wound,
Facilitate operation technique, have again effective maintenance of cable strain.
Background technology
At present, patellar fracture, the especially goldstandard of comminuted fracture of patella treatment are still tension band principle.Common kneecap bone
Folding can use " 8 word " tension band fixation, and what kneecap was pulverized, the avulsion fracture of pole and the kneecap of senile osteoporosis under kneecap
Bone is fractured, and in addition to using " 8 word " tension band fixation, also needs the tension force of cerclage.
The installation of tension band needs cable to run through patellar ligament, strengthens the validity of tension band.The cable of our design is with guide pin
Be conducive to running through patellar ligament.
Fixing in shaft fracture typically can be the most fixing through steel plate, intramedullary nail etc..Duration oblique type fracture is had to need to assist tension band
Fixing.Existing cable is smooth when passing around backbone, even has damaged bone to roll over the risk of surrounding soft tissue.The line of our design
Cable tie has guide pin flexible, according to the diameter pre-bending of fracture, can be conducive to passing around around backbone with pre-bending.
The head of a nail fixed cable of T post is conducive in art the most fixing.
The cable being correlated with now occurs, but still haves much room for improvement.We devise the line of a kind of tension band fixation of fracturing
Cable, is i.e. conducive to alleviating operation wound, facilitates operation technique, has again effective maintenance of cable strain.
Summary of the invention
The invention aims to overcome the deficiency of existing cable strain band internal fixation apparatus, it is provided that solid in a kind of effective tension
Determine equipment.Native system is i.e. conducive to alleviating operation wound, facilitates operation technique, has again effective maintenance of cable strain.Human bone
Dry fracture, patellar fracture etc. needs the optimal selection of tension force immobilized patients.
To achieve these goals, the present invention adopts the following technical scheme that:
A kind of fracture ties up fixing T-Y cable, and this cable is made up of T post, the head of a nail, Y cable and guide pin；It is characterized in that T post
For cylinder, T post one end is provided with end fixing hole (1), and side is provided with side fixing hole (2) and cable hole (3)；Outside head of a nail near-end
Side is set to convex thread (4), and crown center is set to hexagonal groove (5), and head of a nail far-end is provided with U-shaped fixture block (6), and head of a nail far-end sets
There are U-shaped fixture block and plane without fixture block two kinds；Y cable is round metal cable, and Y cable near-end is provided with Y fork angle (7), and far-end is provided with
Stitch (8)；Guide pin near-end is provided with round needle post (9), and far-end is set to the double unimodal pin in angle (10).T post is body length 5-20mm, directly
Footpath 4-8mm, cable hole diameter 3-6mm, be positioned in the middle of T post and be perpendicular to cylinder, and end fixed hole position is in T post one end, with cable
Hole communicates, diameter 2-6mm, lateral orifices diameter 2-6mm, is positioned in the middle of T post, communicates with cable hole and vertical；Head of a nail diameter
2-6mm, thickness 1-4mm, U-shaped card block length diameter 2-6mm, high 1-4mm, U-shaped fixture block is mutually embedding with head of a nail near-end activity；Y cable
For round metal cable, diameter 2-5mm, long 10-50cm, Y cable near-end is provided with Y and pitches angle, near-end cable bifurcated, diameter 1-2.5mm,
Long 5-10mm, is connected with T post, and cable hole and Y cable same plane, Y cable far-end is provided with stitch, with guide pin round needle post
It is connected；Guide pin near-end round needle column diameter 2-5mm, long 2-20cm, flexible, can pre-bending, far-end is provided with the unimodal pin in double angles.
The operation principle of the present invention is: after anaesthetizing successfully, and patient's clinostatism of making even is placed on Orthopedic operation bed, pueumatic tourniquet tie in
Hinder side thigh root, routine disinfection drape.Take kneecap anterior approach, cut skin manadesma, appear kneecap.Give the reduction of the fracture, gram
Family name's pin is indulged the parallel articular surface of shape and is run through kneecap, and " C-arm " has an X-rayed: the Kirschner wire degree of depth is good, is parallel to facies articularis patellae.By leading
Pin runs through kneecap stock ligament and ligamentum patellae through Kirschner wire lower edge, and " 8 word " tension band is tired to be pricked, and guide pin runs through T post cable hole, through lock
Tight device tractive locking, T post side fixing hole or end fixing hole are inserted the head of a nail and lock.Release unnecessary cable and guide pin.Again by leading
Pin lateral branch within Kirschner wire lower edge runs through kneecap stock ligament, kneecap holds ligament and ligamentum patellae, row kneecap cerclage, and guide pin runs through T post
Cable hole, locks through locker tractive, and T post side fixing hole or end fixing hole are inserted the head of a nail and lock.Release unnecessary cable and
Guide pin." C-arm " perspective again: fracture reduction is good to line, and inside-fixture position is good.Check dressing apparatus, close
Otch is also wrapped up.
Beneficial effect:
One, security: drawn cable through patellar ligament, ligamentum patellae and retinaculum patellae by guide pin, will not damage kneecap 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, validity: having multiple cable fixed system on the market at present, clinical practice is extensive.Native system is at existing internal fixation device
Improve on the basis of tool, it is adaptable to human body shaft fracture, the patient, especially comminuted patellar such as patellar 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 patellar fracture, reduce operating time.Be conducive to patient's early recovery.
It is an advantage of the current invention that:
1, the guide pin design that the present invention provides.Guide pin near-end round needle post is flexible, can pre-bending, according to the shape pre-bending of fixing fracture,
So that 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 the present invention provides.T post one end is provided with end fixing hole, and side is provided with side fixing hole, cable hole.Have
It is beneficial 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.The design of T post
Also help the fixing of Y cable.
3, the head of a nail design that the present invention provides.The head of a nail be designed with the pressure beneficially controlling fixed cable, it is to avoid damage cable.Nail
The U-shaped fixture block of cap far-end is designed with and the most at utmost decomposes compression between the head of a nail and cable, adds the fixing intensity of cable.The head of a nail
Distal flat surface is designed with the selection of beneficially side fixing hole without fixture block.
