Background

With the rapid development of society and the improvement of quality of life, bone fracture plates become the common orthopedic implants after rib fracture, and the existing rib bone fracture plates are usually provided with Kirschner wire holes for temporary positioning, but cannot realize corresponding measures of fixing and locking, and usually can only fix two ends of fracture through fixing claws to realize fixing. The rib bone plate fixing claw is usually in a straight plate shape, is relatively complex to implant, needs to be greatly deformed, easily causes secondary trauma in the deformation process, and increases the fracture risk. Chinese patent document 201020111730.6 discloses a rib bone plate, which comprises: the plate main body and the plurality of fixing claws and the plate main body which are symmetrically arranged on two sides of the plate main body are provided with a plurality of round holes which are uniformly distributed and used for temporary positioning. As described above, the bone plate has the following problems.

1. The fixation is carried out only by the fixing claws, so that the butt joint mode lacks stability, slippage and displacement are easy to occur, bones cannot heal or malformation heals, and the risk of product fracture is increased.

2. The fixing claw is in a straight plate shape, the fixing claw needs to be bent and attached to the affected bone by a tool when the fixing claw is implanted, secondary wound is easily caused to the affected bone in the bending process, the deformation of a product is large, and the fracture risk is increased.

3. The round holes arranged on the plate main body only play a role in temporary positioning, and the reliable and firm butt joint of the two ends of the fracture cannot be ensured.

SUMMERY OF THE UTILITY MODEL

The utility model provides a pre-compression rib coaptation board can make the sick bone butt joint firm to the effectual fracture risk that reduces rib board:

the utility model discloses technical scheme as follows:

a pre-pressing rib bone fracture plate comprises a cross beam and encircling arms symmetrically arranged on two sides of the cross beam, wherein the encircling arms and the cross beam are integrally formed, and the thickness of the encircling arms is thinner than that of the cross beam; and a threaded hole is formed at the intersection of the central line of the cross beam and the central line of each pair of encircling arms.

The shape of the encircling arm is matched with that of the rib.

The encircling arms are 2-8 pairs.

The cross beam is of one of a flat structure or an arc structure.

Detailed Description

Referring to fig. 1, 2 and 3, the pre-pressing type rib bone fracture plate comprises a cross beam 2 and encircling arms 1 symmetrically arranged on two sides of the cross beam 2, wherein the encircling arms 1 and the cross beam 2 are integrally formed, and the thickness of the encircling arms is thinner than that of the cross beam; and a threaded hole 3 is formed at the intersection of the central line of the cross beam 2 and the central line of each pair of encircling arms 1.

The end part of the encircling arm 1 is arc-shaped or is bent towards one side of the cross beam 2, the encircling arm 1 is matched with the shape of the rib according to the shape design of the section of the rib, the encircling arm 1 has 2-8 pairs of various forms, the left side and the right side are symmetrically arranged, the encircling arm inwards encircles, a prepressing effect is achieved, the two ends of the fracture can be more stably and firmly fixed, the fracture risk is reduced, and the operation difficulty is reduced.

The cross beam 2 is one of a flat structure or an arc structure, the cross beam 2 is basically a flat plate, but can be bent downwards to a certain radian along the direction vertical to the cross beam according to the radian of the ribs when the product is used at different ribs and positions so as to be tightly attached to the ribs when in use.

The connecting end of the encircling arm 1 and the cross beam 2 is in a round angle shape, and the connecting strength of the encircling arm 1 and the cross beam 2 is enhanced.

The two sides of the middle section of the beam 2 are not provided with the encircling arms 1, so that the stress of the encircling arms on the broken ends of the bones is eliminated in order to avoid the fracture and damage parts of the ribs.
