Description

Leading-out device

Technical Field

The utility model relates to a ridge fracture fixed technical field between shin bone condyle, in particular to steel wire guiding device.

Background

And (3) reconstructing a tibial tunnel guider by adopting a bone tunnel high-strength line 8-shaped suture or steel wire winding and fixing method, positioning an outlet at the periphery of the fractured tibial intercondylar crest fracture, drilling holes, threading a diagonal line through the base part of the anterior cruciate ligament, knotting a line end, and fixing the line end on the anterior inner side of a tibial tubercle. The bone tunnel comprises an introduction tunnel and a derivation tunnel, the introduction process is easy to realize, and in the process of deriving the steel wire and the suture, the damage to articular cartilage and meniscus around the derivation tunnel mouth and the prolongation of the operation time caused by the repeated derivation after the steel wire is bent are still difficult to avoid although the steel wire and the suture are assisted by an arthroscope at present.

Disclosure of Invention

In order to solve the technical problem, an object of the present invention is to provide a guiding device, which has the features of reducing meniscus and cartilage damage and saving operation time.

In order to realize the purpose, the utility model discloses a technical scheme is:

the utility model provides a derivation device, is including deriving pincers and dull polish head steel wire 8, and dull polish head steel wire 8 is used for passing crest fracture between bone tunnel after-fixing shin bone condyle, derives pincers and includes handle one 1 and handle two 2, handle one 1 and handle two 2 cross connection, the cross section is provided with pin 3, handle one 1 and handle two 2 of 3 below of pin between be provided with spring 4, be located handle one 1 top and be provided with horizontally ring pipe 5, handle two 2 top levels are provided with the pole, the tip of pole is provided with binding clip 6, the pole pass ring pipe 5, binding clip 6 is located the ring pipe 5 outside.

And an annular clamping groove 7 is formed between the first handle 1 and the annular pipe 5, and the first handle 1 pushes the annular pipe 5 to move forwards in the horizontal direction.

The front end of the binding clip 6 is of a petal-shaped structure, the petal-shaped surface is circular, a certain gap is reserved between the petal shapes, the rear end of the binding clip 6 is arranged on the rod, and the maximum diameter of the elastic petal-shaped structure is 0.8 mm.

The inner side of the petal-shaped structure is a non-smooth surface with certain elasticity.

The steel wire and the binding clip 6 are connected by occlusion.

The contact end of the sanding head steel wire 8 and the tong head 6 is a sanding surface structure.

The length of the steel wire 8 of the sanding head is 40cm consistent with that of a common steel wire, the diameter of the steel wire is 0.8mm, and the length of the structure of the sanding surface is 0.5 cm.

The diameter of the annular pipe 5 is about 2.0mm, and the length is 15 cm.

The utility model has the advantages that:

ridge fracture steel wire bundle art formula between traditional shin bone condyle, the steel wire passes the shin bone from the shin bone outward and arrives articular cavity comparatively smoothly, nevertheless when wearing out the shin bone from articular cavity, the steel wire often needs the search shin bone derivation hole and repeated bending, can lead to the meniscus, the damage of cartilage and the extension of operating time, the beneficial effect of this device lies in leading-out hole in advance with the pincers body, binding clip 6 gets into the joint, no matter be open operation or minimal access arthroscopic surgery, all can be connected the head interlock of binding clip 6 and dull polish head steel wire, pull out the shin bone with the steel wire afterwards, reduction that can to a great extent, cause the damage at tunnel portal peripheral articular cartilage and meniscus, and save operating time.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic structural view of the binding clip 6.

Fig. 3 is a structural side view of the binding clip 6.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1: grinding head steel wire 8 is used for passing bone tunnel back fixed shin bone intercondylar ridge fracture, derivation pincers utilize handle one 1 and handle two 2, on the pin 3 at middle part, with pin 3 cross connection together, make both ends can the relative activity, as long as with hand operation handle one 1, just can make the annular tube 5 push forward through handle one 1 for annular tube 5 moves to binding clip 6 department, because binding clip 6 is elasticity petal column structure, make binding clip 6 shrink, thereby the steel wire dull polish end of the grinding head steel wire 8 of pinching.

As shown in fig. 2 and fig. 3: the front end of the binding clip 6 is of a petal-shaped structure, the petal-shaped surface is circular, a certain gap is reserved between the petal shapes, the rear end of the binding clip 6 is arranged on the rod, and the petal-shaped structure is 0.5 cm.

The utility model discloses a theory of operation:

the suture line passes through the leading-in bone tunnel and stays in the joint, the leading-out forceps are occluded with the frosted end of the frosted head steel wire 8 or the suture line under the direct vision through the leading-out bone tunnel, and the suture line is led out of the joint and fixed or knotted. The steel wire or the suture can be led out in a time-saving manner, damage to the articular surface and the meniscus can be reduced, and the advantages are reflected.
