Description

Auxiliary tibial plateau resetting pad

Technical Field

The utility model relates to an orthopedic surgery utensil field, concretely relates to supplementary pad that resets of tibial plateau.

Background

Tibial plateau fractures are often caused by high energy trauma, such as: high falling injury, traffic accident injury, falling injury and the like. As the tibial plateau is an important load structure of the lower limb, when the tibial plateau is subjected to severe vertical, varus and valgus violence, the tibial plateau often causes bony structural damage, which is often manifested by fracture of the tibial plateau by cleavage, accompanied or not accompanied by collapse of the joint surface, and even the dislocation of the knee joint and metaphysis crushing of the severe tibial plateau. The soft tissues surrounding the knee joint and the joint stabilizing structures (medial and lateral collateral ligaments, meniscus and cruciate ligaments) will also be affected. Therefore, the treatment of tibial plateau fractures has been a hotspot and difficulty in trauma orthopedics.

At present, complex tibial plateau fracture refers to internal and external side double-plateau fracture, common tibial plateau fracture refers to single side, and during tibial plateau fracture surgery, no matter the inboard or the outside platform, the point type reduction forceps are often used for reduction in a reposition mode, and stress points are concentrated in the form, so that the reduction effect is poor, the rotation of a fracture block can be caused, the stress points are damaged, and even new fracture is caused. In addition to reduction of reduction forceps, the reduction forceps are reduced by hands or screws, and the two methods are difficult to maintain, stress points are concentrated, and sometimes the rotation of a fracture block is difficult to control.

SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, the utility model provides a supplementary pad that resets of tibial plateau increases the atress area that resets, realizes wholly resetting.

The utility model discloses a supplementary pad that resets of tibial plateau, including the pad body that resets, should reset and fill up the body and be arc piece formula structure, its surface is equipped with a plurality of first punch combination along arc direction parallel, first punch combination includes the first fixed orifices that a plurality of intervals set up, it has a plurality of second punch combination to be located between two first punch combination along arc direction parallel arrangement to reset pad body surface, the second punch combination includes the second fixed orifices that a plurality of intervals set up, it is protruding that the pad body back that resets is equipped with a plurality of toper.

Preferably, the first fixing hole is a kirschner wire fixing hole, and the diameter of the first fixing hole is 2.2 mm.

Preferably, the second fixing hole is a point type reduction forceps fixing hole, and the aperture is 1 mm.

Preferably, the conical bulge is a conical bulge, the height of the conical bulge is 1mm, and the diameter of the conical bottom is 2 mm.

Preferably, the radian of the reduction pad body is consistent with the radians of the inner side and the outer side of the tibial plateau.

The beneficial effects of the utility model are embodied in: the utility model provides a supplementary pad that resets of tibial plateau, has following beneficial effect:

the arc-shaped sheet structure is adopted to wrap the whole side surface of the tibial plateau during reduction, so that the stress area between the reduction pad and the fracture block is increased, and the fracture block is reduced integrally;

the Kirschner wire fixing hole and the point type reduction forceps fixing hole are synchronously arranged, the effective position of the reduced fracture block is temporarily maintained through the Kirschner wire, and meanwhile, the reduction pad and the fracture block are fixed into a whole, so that the reduction is facilitated; point type reduction forceps fixing holes at a plurality of positions realize that the reduction forceps reduce and adjust the fracture block in different directions;

the back of the reset pad is provided with the conical bulge, so that the holding force between the reset pad and the fracture block can be increased, and the relative sliding is reduced, thereby avoiding the loss of reset.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

The utility model discloses a supplementary pad that resets of tibial plateau, this pad 1 that resets are located tibial plateau 2's medial surface or lateral surface, or lie in inside and outside both sides face (as the position in figure 4) in step, specific pad structure that resets is shown as figure 1~3, including pad body 3 that resets, this pad body that resets is arc piece formula structure, its radian is unanimous with the radian of tibial plateau inside and outside, ensures the laminating nature, and this pad body that resets has certain elasticity simultaneously, can increase the laminating nature through external force when not laminating completely, the pad that resets is just looked for the rectangle, and its width is 2~3cm, and thickness is 3mm, and length has 4cm, 5cm and three kinds of sizes of 6cm to adapt to different crowds.

The utility model discloses a reset pad body, reset pad body and reset pincers, reset pad body surface is equipped with a plurality of first punch combination along arc direction parallel, and this first punch combination includes first fixed orifices 4 that a plurality of intervals set up, and first fixed orifices is the kirschner wire fixed orifices, and the aperture is 2.2mm, reset pad body surface still parallel arrangement has a plurality of second punch combination to be located between two first punch combination along arc direction, second punch combination includes the second fixed orifices 5 that a plurality of intervals set up, the second fixed orifices is point type pincers fixed orifices that resets, and the aperture is 1 mm. The second fixing hole and the first fixing hole can be arranged in the same straight line or in a staggered mode.

The back of the reset pad body is provided with a plurality of conical bulges 6 which are conical bulges, the height of the conical bulges is 1mm, the diameter of the cone bottom is 2mm, the conical bulges can be distributed on the back of the reset pad body in a mess manner when being distributed, and can also be distributed in a regular matrix manner, and the conical bulges abut against fracture blocks when in use, so that the mutual holding force is increased.

The utility model discloses a supplementary pad that resets of tibial plateau, when tibial plateau is simple splitting fracture, the tibial plateau unilateral or two sides will reset the pad body when it uses, with fracture piece parcel in, cooperate the point type clamp that resets to hold simultaneously and reset, squeeze into the ke shi needle after confirming the effective position that resets and carry out interim fixing, get rid of the gasket that resets again, put into internal fixation device. When the fracture block has rotary displacement and is not well restored by simply clamping the fracture block, a Kirschner wire can be temporarily placed into the Kirschner wire through a Kirschner wire hole to form the restoration pad body and the fracture block of the tibial plateau into a whole, and meanwhile, the rotation and the separation are controlled by being matched with the clamping of the point type restoration forceps and the restoration is carried out.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
