Specifically, the artificial rib of the present embodiment includes three parts: the stretching device comprises a first stretching structure 1, a second stretching structure 2 and a stretching cavity 3, wherein one ends of the first stretching structure 1 and the second stretching structure 2 are respectively arranged at two ends of the stretching cavity 3, and can be stretched outwards from the stretching cavity 3. The other ends of the first stretching structure 1 and the second stretching structure 2 are respectively a first connecting end and a second connecting end. When the artificial rib is placed laterally within the chest cavity, the first connecting end may be connected to a vertebra and the second connecting end may be connected to the sternum. Alternatively, the first connecting end is connected to the sternum and the second connecting end is connected to the vertebrae. This is not limited thereto. When the artificial rib of the embodiment is longitudinally placed in the chest, the first connecting end and the second connecting end can be connected with other ribs in the up-down direction. The inclined plane of the limiting teeth 5 and the included angle of the stretching direction are larger than 90 degrees, so that the relative resistance between the first stretching structure 1 or the second stretching structure 2 and the limiting structures on two sides of the track when being pulled out is reduced.
The first stretching structure 1 and the second stretching structure 2 may be on the same horizontal plane, and in order to shorten the length of the stretching cavity 3, the first stretching structure 1 and the second stretching structure 2 may also be located in the upper layer and the lower layer in the stretching cavity 3.
As shown in fig. 5, a first limiting block 9 is disposed at the front end of a through groove 13 corresponding to a first limiting tooth of the first stretching structure 1 and the second stretching structure 2 in the stretching direction, and second limiting blocks 12 matched with the first limiting block 9 are disposed at two ends of the stretching cavity 3.
Specifically, when the first stretching structure 1 and the second stretching structure 2 are stretched outwards to the front end of the limiting teeth under the action of external force, in order to prevent the limiting teeth from extending out of the stretching cavity 3 to damage human tissues, a first limiting block 9 is arranged at the front end of the stretching structure through groove 13, and a second limiting block 12 is arranged at two ends of the stretching cavity 3. The second limiting block 12 is matched with the first limiting block 9, and the stretching structure is prevented from stretching outwards continuously. The first limiting block 9 can be arranged at the top of the stretching structure, can be arranged at the bottom of the stretching structure, and can be arranged at the top and the bottom simultaneously. The second limiting block 12 is arranged at the top, the bottom or both the top and the bottom of the stretching cavity 3 according to the position where the first limiting block 9 is arranged.
As shown in fig. 4, the width of the first limiting block 9 is smaller than the width of the through groove 13, a first side through groove 7 and a second side through groove 8 are formed on two sides of the first limiting block 9, the total width of the first side through groove 7, the second side through groove 8 and the first limiting block 9 is equal to that of the through groove 13, the lengths of the first side through groove 7 and the second side through groove 8 are greater than that of the first limiting block 9, round holes 18 are formed in the top ends of the first side through groove 7 and the second side through groove 8, and peek materials are injected into the first side through groove 7 and the second side through groove 8.
Specifically, the total width of the stopper and the first side through groove 7 and the second side through groove 8 on both sides thereof in the present embodiment is equal to the width of the through groove 13. The through grooves 13 are stressed inwards by the limiting teeth 5 during the outward stretching movement of the first stretching structure 1 and the second stretching structure 2. The circular holes 18 at the top ends of the first side through groove 7 and the second side through groove 8 disperse stress at the end of the through groove 13. The first tensile structure 1 and the second tensile structure 2 are prevented from splitting under stress. The PEEK material is injected into the first side through groove 7 and the second side through groove 8, and the impact force of the first limiting block 9 and the second limiting block 12 is buffered due to elasticity of the PEEK material. The secondary injury of human tissues caused by the damage of the artificial ribs is prevented.
Further, the height of the limiting teeth 5 decreases gradually along the stretching direction, and the distance between the through groove 13 and the edges of the first stretching structure 1 and the second stretching structure 2 decreases along the stretching direction.
Specifically, as the human body grows, the hardness of the bone increases. The outward tensile stress of the first tensile structure 1 and the second tensile structure 2 also becomes gradually larger. Therefore, the height of the spacing teeth 5 decreases in sequence in the stretching direction. I.e. the innermost limiting tooth height is greatest. The stress of the limiting teeth on the stretching structure is increased correspondingly to the increase of the height of the limiting teeth, so that the distance between the through groove 13 and the edges of the first stretching structure 1 and the second stretching structure 2 is reduced along the stretching direction. The height and distance change is further adapted to the human body production process, and the service life of the artificial rib is prolonged.
As shown in fig. 3 and 4, further, the limiting teeth 5 are right triangle teeth, and the limiting structure is a double inverted tooth 6 protruding on the track or a clamping groove 10 embedded in the track.
Specifically, the first stretching structure 1 and the second stretching structure 2 of the artificial rib of the embodiment complete biaxial stretching through the drawing type track arranged in the stretching cavity 3. One end of the first stretching structure 1 and one end of the second stretching structure 2, which are arranged in the stretching cavity 3, are provided with limiting teeth 5, as shown in fig. 3, the limiting teeth 5 are triangular teeth, and the limiting structure is a double inverted tooth 6 opposite to the limiting teeth 5; as shown in fig. 4, the limiting teeth 5 are triangular teeth, and the limiting structure may also be a clamping groove 10 opposite to the limiting teeth 5. The spacing teeth may also be other shapes. When the first stretching structure 1 and the second stretching structure 2 stretch outwards from the inside of the stretching cavity 3, the limiting teeth 5 deform inwards through the through grooves 13 formed in the first stretching structure 1 and the second stretching structure 2, and after moving outwards to the position of the limiting structure, the limiting structure prevents reverse movement.
Further, as shown in fig. 2, a sealing ring 11 is disposed at the joint of the stretching cavity 3 and the first stretching structure 1, and the second stretching structure 2, one end of the sealing ring 11 is clamped with the stretching cavity, and a reinforcing ring is disposed at the other end of the sealing ring.
Specifically, as shown in fig. 6, in this embodiment, a sealing ring 11 is provided at the connection between the stretching chamber 3 and the first stretching structure 1 and the second stretching structure 2, and the sealing ring 11 can prevent tissue from growing into the stretching chamber. Resulting in the first stretched structure 1 and the second stretched structure 2 not being stretched outwards.
