[0002] When a human rib is fractured, the rib needs to be fixed using a rib fixation device. A rib plate is a commonly used medical device in rib fixation surgery.
[0003] When there are multiple fractures on the same rib, the existing rib bone plate is composed of a longer bone plate body with bone claws at both ends, so that the fracture areas where the bone claws at the two ends are located are associated, thereby increasing the stability of internal fixation.
[0004] However, the existing rib bone fracture plate has a long bone fracture plate body, which is usually a plate-shaped whole. When the human body inhales and exhales, the ribs move with the human body's breathing, thereby causing the bone fracture plate body to deform, but the bone fracture plate body of the existing rib bone fracture plate is difficult to deform with the human body's breathing. Utility Model Content

In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0028] The rib bone plate of the present utility model is used to connect the rib fracture site. Specifically, the rib bone plate of the present utility model is used to connect a rib with at least two fractures into an integral rib.
[0029] Such as Figures 1 to 4As shown, the rib bone plate of the present utility model includes a bone-holding part 1 and a bending part 2. At least two bone-holding parts 1 are provided, and the bending part 2 is connected between two adjacent bone-holding parts 1. The bone-holding part 1 includes a bone-holding member 1a connected to the bending part 2 and a number of bone-holding claws 1b arranged on both sides of the bone-holding member 1a. The bending part 2 includes a fixing member 2a and a bending member 2b connected to the fixing member 2a. The bending direction of the bending member 2b faces towards or away from the rib direction. Two fixing members 2a are provided, the bending member 2b is arranged between the two fixing members 2a, and the fixing member 2a is connected to the bone-holding member 1a. In this embodiment, two bone-holding parts 1 are provided, one bending part 2 is provided, and the bending part 2 is arranged between the two bone-holding parts 1. The bone-holding part is used to connect the rib fracture site. Therefore, the rib bone plate of this embodiment is mainly used in the operation of a rib with two fractures. In other embodiments, as Figure 4 shown, three bone-holding parts 1 may also be provided, and two bending parts 2 are provided. Then the rib bone plate of this embodiment is mainly used in the operation of a rib with three fractures.
[0030] When using the rib bone plate of the present utility model to fix a rib with multiple fractures, the bone-holding part 1 connects the fracture site. The fractured rib moves due to the expansion or contraction of the lungs brought about by human breathing, thereby driving a change in the relative position between the bone-holding parts 1. Since the bending direction of the bending member 2b is limited to face towards or away from the rib direction, the bending part 2 can only deform towards or away from the human body.
[0031] By arranging the bending part 2 between two adjacent bone-holding parts 1 of the rib bone plate of the present utility model, due to the arrangement of the bending part 2, the bone-holding parts 1 are connected to each other. When breathing causes a change in the relative position between the bone-holding parts 1, since it is limited that the bending member 2b in the bending part 2 can only deform towards or away from the human body, the rib bone plate as a whole can only deform towards or away from the human body. While ensuring the association of each fracture area along the rib direction and ensuring the internal fixation stability of the rib bone plate, it is convenient for the rib bone plate as a whole to deform due to human breathing.
[0032] In this embodiment, as Figure 1 、 Figure 3 and Figure 5 shown, both the fixing member 2a and the bending member 2b are made of a metal plate, and a hollow area is engraved on the bending member 2b by a subtractive manufacturing method. By providing a hollow area on the bending member 2b of the present utility model, the stiffness of the bending member 2b in the direction towards or away from the human body is reduced, facilitating the deformation of the bending member 2b. In other embodiments, the bending member 2b is an elastic member, such as a spring piece.
[0033] In this embodiment, for the convenience of better reflecting the hollowed-out area in Figure 3 , Figure 5 the solid parts of the fixing member 2a and the bending member 2b are represented by a mesh. As Figure 3 and Figure 5 shown, the hollowed-out area is a plurality of adjacent hollowed-out grooves. The hollowed-out groove includes a first hollowed-out strip 2ba and second hollowed-out strips 2bb respectively connected to both ends of the first hollowed-out strip 2ba. The first hollowed-out strip 2ba and the second hollowed-out strips 2bb are connected to form a "C" shape. The two second hollowed-out strips 2bb of each hollowed-out groove respectively enter the "C" shape opening of the adjacent hollowed-out groove. The utility model adopts the method of defining the hollowed-out area to hollow out a plurality of "C" shaped grooves, so that the stiffness of the bending member 2b meets the deformation requirements brought by human breathing, and meets the connection requirements between the bone-holding parts 1. In other embodiments, the hollowed-out area is a plurality of third hollowed-out strips arranged in parallel, but the use effect of the rib bone plate in this embodiment is better than that in this embodiment.
[0034] In this embodiment, as Figure 1 and Figure 2 shown, the bone-holding claws 1b are made of shape memory alloy. By setting the bone-holding claws 1b to be made of shape memory alloy, during the operation, the bone-holding claws 1b can automatically hold the ribs tightly at the human body temperature, reducing the operation difficulty and shortening the operation time.
[0035] In this embodiment, as Figure 1 shown, the bone-holding claws 1b located on both sides of the bone-holding member 1a are arranged alternately in sequence. By setting the bone-holding claws 1b to be arranged staggeredly, compared with the generally symmetrically distributed bone-holding claws 1b on the market, the bone-holding claws 1b arranged staggeredly can form a larger contact area when holding the ribs tightly, can better wrap the broken bones, and generate a greater frictional force to prevent the ribs from shifting laterally.
[0036] In this embodiment, as Figure 1 shown, the bone-holding claws 1b arranged on one side of the bone-holding member 1a are arranged at equal intervals. By setting the bone-holding claws 1b arranged on one side of the bone-holding member 1a at equal intervals, it is convenient for the bone-holding claws 1b to better join the fractured ribs.
[0037] In this embodiment, as Figure 1 shown, the bone-holding member 1a is provided with bone-holding claw positioning holes 1c. By providing the bone-holding claw positioning holes 1c, fixing nails can be used to pass through the bone-holding claw positioning holes 1c, so as to fix the bone-holding part 1 to the ribs.
[0038] In this embodiment, Figure 1 As shown, the number of the bone-holding claw positioning holes 1c is the same as the number of the bone-holding claws 1b arranged on one side of the bone-holding member 1a. The utility model facilitates stable fixation between the bone-holding part 1 and the ribs by limiting the number of the bone-holding claw positioning holes 1c.
[0039] In summary, the utility model provides the bending part 2 between two adjacent bone-holding parts 1 of the rib bone fracture plate, and due to the setting of the bending part 2, the bone-holding parts 1 are connected to each other. When the relative position of the bone-holding parts 1 changes due to breathing, the bending part 2b in the bending part 2 is limited to be deformed only toward the human body or away from the human body, so that the rib bone fracture plate as a whole can only be deformed toward the human body or away from the human body, while ensuring the association of the fracture areas along the rib direction and the stability of the internal fixation of the rib bone fracture plate, it is convenient for the deformation of the rib bone fracture plate as a whole due to human breathing. And by providing a hollow area on the bending part 2b, the rigidity of the bending part 2b in the direction toward the human body or away from the human body is reduced, which is convenient for the deformation of the bending part 2b. And by limiting the hollow area to hollow out a number of "匚"-shaped grooves, the rigidity of the bending part 2b meets the deformation requirements caused by human breathing and the connection requirements between the bone-holding parts 1. And by setting the bone-holding claws 1b to be made of memory alloy, the bone-holding claws 1b can automatically hold the ribs at human body temperature during the operation, reducing the difficulty of the operation and reducing the operation time. And by setting the bone-holding claws 1b to be staggered and distributed, compared with the symmetrically distributed bone-holding claws 1b commonly used on the market, the staggered bone-holding claws 1b can form a larger contact area when holding the ribs, which can better wrap the broken bones and generate greater friction to prevent the ribs from shifting laterally. And by setting the bone-holding claws 1b on one side of the bone-holding part 1a at equal intervals, it is convenient for the bone-holding claws 1b to better join the fractured ribs. And by setting the bone-holding claw positioning holes 1c, a fixing nail can be used to pass through the bone-holding claw positioning holes 1c, so as to fix the bone-holding part 1 to the ribs. And by limiting the number of the bone-holding claw positioning holes 1c, it is convenient to achieve stable fixation between the bone-holding part 1 and the ribs.
[0040] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
