Abstract
The invention provides a krischner wire with a sliding sleeve, is used for multiple-fracture treatment, and belongs to orthopedics instruments. The sliding sleeve (2) is sleeved in a wire body section of the krischner wire (1), the wire body section of the krischner wire is provided with one or two bosses (3), the sliding sleeve can freely rotate along a vertical axis in the wire body and is limited by the bosses to be not capable of moving up and down obviously along the vertical axis of the wire body, a hole (4) is arranged on or an ear-shaped handle (10) with holes is protruded a side of the sliding sleeve , tension band materials (7) are facilitated to attach to the sliding sleeve. An annular pre-breaking incisura (6) is arranged at a junction between a wire tail end of the krischner wire and the bosses (3) on wire tail side to facilitate to break the wire tail end. The krischner wire and the tension band materials are integrated linked through the sliding sleeve to limit the krischner wire to move in bones, so that the operation is facilitated, and fixing is reliable; and the krischner wire, the sliding sleeve and the tension band materials can be made of metal or high molecular materials, and can be sterilized in an integral package.
Description
Technical field
The invention belongs to a kind of orthopedic medical device, specifically a kind of Kirschner wire that can be used for the band sliding sleeve of multiple fracture treatment.
Technical background
The orthopedist often adopts Kirschner wire treatment patella, olecroanon, femoral greater trochanter and other epiphysis avulsion fracture at present, it is easy and simple to handle, economical and practical, but Kirschner wire slip migration, inconvenient bending can appear in using, steel wire is not pressed close to epiphysis and slippage, Kirschner wire and steel wire do not match, postoperative can not early ambulant etc. problem Give doctor and patient bring a lot of worries, cause unnecessary dispute, therefore the use of common Kirschner wire reduces gradually.People have carried out a lot of improvement to it, multiple kirschner wire with hole occurred, but how to hole at the Kirschner wire needle body, as " kirschner wire with hole " (patent No. 2334356Y) that announced on August 25th, 1999, have reduced the intensity of Kirschner wire on the one hand; Can't penetrate the tension band material on the other hand in advance and carry out the fracture fixation drilling operation, use very inconvenient.
Summary of the invention
The present invention can solve above-mentioned deficiency, provides a kind of rational in infrastructure, easy to use, and fixation can be used for the Kirschner wire of the band sliding sleeve of multiple fracture treatment.Needle body section at Kirschner wire (1) is with a sliding sleeve (2), the needle body Duan Youyi of Kirschner wire (3) or two boss (3) (8), sliding sleeve can rotate freely along the needle body longitudinal axis, sliding sleeve is limited by boss and can not have along the needle body longitudinal axis and significantly moves up and down, one of in the following manner the restriction sliding sleeve moves up and down: 1, sliding sleeve (2) parcel boss (3), 2, on the Kirschner wire needle body of sliding sleeve both sides a boss (3) (8) is arranged respectively, 3, can be a bit of screw thread (8) that is raised in the Kirschner wire surface near the boss of the Kirschner wire needlepoint side of sliding sleeve.Sliding sleeve can have multiple shape, discoid, hollow drops (be applicable to above-mentioned first kind of mode: parcel boss (3) restriction sliding sleeve moves up and down) as hollow, also can be solid discoid or circular (be applicable to above-mentioned second or the third mode limit sliding sleeve and move up and down), the side of sliding sleeve has the lug (10) of 1-2 hole (4) or projection one porose (9) in addition, be convenient to tension band material (7) and in the hole, pass, so that Kirschner wire, sliding sleeve, the link of tension band material become a complete tension band internal fixation system.The tail side of Kirschner wire tail side boss (3) partly is one section multiple edge body (5), is convenient to use when internal fixation takes out or tightens.Kirschner wire backshank section and backshank side boss (3) intersection are established an annular pre-break incisura (6), are convenient to cracking-off backshank section.Kirschner wire, sliding sleeve and tension band can be selected metal material or macromolecular material for use.Above-mentioned Kirschner wire, sliding sleeve, a kind of tension band internal fixation system that can be used for the multiple fracture treatment of the common formation of tension band material three.
This tension band internal fixation system can be used as the entire package sterilization, is convenient to emergency treatment and uses.

Accompanying drawing 3 has the enlarged diagram of the sliding sleeve of hole lug for filled circles plate-like of the present invention
Accompanying drawing 4 is user mode sketch map of the present invention
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in detail.
As shown in Figure 2, needle body section backshank side at Kirschner wire (1) has a boss (3), needlepoint side has a bit of screw thread (8) that is raised in the Kirschner wire surface, between boss (3) and screw thread (8), be with a sliding sleeve (2), sliding sleeve (2) can rotate freely along the needle body longitudinal axis, but sliding sleeve (2) is by boss (3) and screw thread (8) restriction, can not have significantly along the needle body longitudinal axis and move up and down, the lug (10) of the side projection one porose (9) of sliding sleeve, being convenient to tension band material (7) passes in hole (9), the tail side of Kirschner wire tail side boss (3) partly is one section multiple edge body (5), is convenient to use when internal fixation takes out or tightens.The Kirschner wire backshank is close to boss (3) intersection and establishes an annular pre-break incisura (6), is convenient to cracking-off backshank section.Sliding sleeve is linked into an integral body with Kirschner wire and tension band material, can limit the slip of Kirschner wire in bone.
As shown in Figure 4, be example with the Patella fracture: after the reduction of the fracture, pass the fixing fracture of the longitudinal axis of patella with two Kirschner wires that overlap the designed band sliding sleeve of the present invention and [can in advance the tension band material be passed the hole (9) on the sliding sleeve lug (10), can not influence the operation of Kirschner wire rotary drilling], the tension band material can be walked around needlepoint side from the patella leading edge and tighten, also can pass quadriceps femoris tendon and kneecap tendon Kirschner wire ' 8 ' the word ring of two cover band sliding sleeves is pricked, cracking-off backshank section is wiped out unnecessary needle point.Slide up and down owing to Kirschner wire can't break away from the tension band material, become the mutually integral body of restriction with the Kirschner wire of sliding sleeve and the patella of tension band material and fracture this moment, makes fracture obtain good fixing.After the union of fracture, cut off tension band, the supporting instrument counter-rotating of use and backshank multiple edge body can be taken out the Kirschner wire of band sliding sleeve.
