Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, the embodiment of the present utility model provides a thoracic member which is convenient for rapid fixation and connection, and includes a sternum plate 1 and rib plates 2, wherein at least one rib plate 2 is respectively disposed at both sides of the sternum plate 1, and the rib plates 2 and the sternum plate 1 are respectively formed in a three-dimensional arc shape to simulate formation of a thoracic cavity. A first clasp 11 is formed at the top of the aforementioned sternum plate 1, and a second clasp 21 is formed at the distal end of at least one of the rib plates 2 (i.e. the end of the rib plate 2 remote from the sternum plate 1), wherein the first clasp 11 is used to secure the sternum plate 1 to the sternum by clasp at the manubrium and the second clasp 21 is used to secure the rib plate 2 to the ribs.

Further, the first holes 12 are provided in the sternum plate 1, and the plurality of first holes 12 are arranged along the length direction of the sternum plate 1. The rib plate 2 is provided with a second hole 22 and a third hole 23, and a plurality of second holes 22 and a plurality of third holes 23 are arranged along the length direction of the rib plate 2, while the third holes 23 are closer to the distal end of the rib plate 2 than the second holes 22. In this embodiment, the third hole 23 is used to fix the rib plate 2 to the rib by bone nails, the second hole 22 is used for drainage to facilitate the growth of tissue into the second hole 22, and the second hole 22 can also be used to fix the rib plate 2 to the rib by bone nails.

In this embodiment, in order to distinguish the second hole 22 from the third hole 23, the second hole 22 is marked with a rectangular hole, the third hole 23 is marked with a circular hole, and in the practical application process, the second hole 22 and the third hole 23 may be identical in shape.

Since the incomplete rib is generally fractured, the third hole 23 is used as a fixing hole, so that the connection point between the rib plate 2 and the incomplete rib can be arranged at the middle section of the rib, and the possibility of increasing the fracture area caused by the incomplete rib when the rib is perforated is reduced. The second hole 22 is then used for drainage or for auxiliary fixation, depending on the patient's situation.

Further, the first buckle 11 is formed by bending the top end of the sternum plate 1 by 180 °. The aforementioned second buckle 21 includes two wings 221, the two wings 221 are formed on two sides of the distal end of the rib plate 2, and the two wings 221 are used for being clamped on the rib to fix the rib plate 2 on the rib.

Furthermore, the rib plate 2 is provided with a net structure on one surface contacted with the rib, and the net structure is utilized to promote tissue growth, so that tissues can be attached to the net structure, and the connection stability between the rib and the rib plate 2 is further enhanced.

Preferably, the sternum plate 1 and rib plate 2 are integrally formed by 3D printing techniques using TC4 material.

Taking this embodiment as an example, when a thoracic member convenient for rapid fixation and connection needs to be manufactured, a 3D scanning technique is adopted to construct a patient's sternum and rib model, the thoracic member convenient for rapid fixation and connection is formed by targeted printing according to the injury degree of the patient's rib, then the thoracic member convenient for rapid fixation and connection is placed into the chest of the patient, the rib plate 2 is kept connected with the rib, and the sternum plate 1 is connected with the sternum.

According to different conditions of the patient, when one rib of the patient is missing, the rib plate 2 positioned on one side of the sternum plate 1 is initially connected with the incomplete rib through the second buckle 21, and the rib plate 2 is fixed on the rib by using the third hole 23 and the bone nail; while the rib plate 2 on the other side can be fixed to the intact rib via the second aperture 22 and/or the third aperture 23. Of course, the rib plate 2 on the other side may also be provided with a second buckle 21 to facilitate connection of the intact ribs.

When the two side ribs of the patient are missing, the rib plates 2 on the two sides of the sternum plate 1 are connected with the incomplete ribs preliminarily through the second buckles 21, and the rib plates 2 on the two sides are fixed on the ribs by the third holes 23 and the use of bone nails.

In the application, the first buckle 11 is adopted to fix the sternum plate 1 and the sternum, a main stress structure is formed between the first buckle 11 and the sternum, and only a small amount of first holes 12 are needed to be punched on the sternum, so that the positioning and auxiliary supporting effects of the first holes 12 are realized, the damage to the sternum is reduced, and the recovery of a patient is facilitated.

Meanwhile, the functions of the second hole 22 and the third hole 23 are distinguished, so that the third hole 23 can only be used as a fixing hole, the rib plate 2 is conveniently fixed at the middle part far away from rib injury, secondary damage to the injury part caused by fixing the rib plate 2 by bone nails is prevented, and the recovery time of a patient is prolonged. While the second aperture 22 is selected for drainage or to aid fixation, depending on the individual condition of the patient.

While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present utility model, and such modifications and adaptations are intended to be comprehended within the scope of the present utility model.
