It should be noted that, the sliding grooves 13 on the first locking section 11 and the second locking section 12 are respectively located at two sides of the fractured bone gap 6, and one end of the sliding groove 13 away from the fractured bone gap 6 is called a distal end, and correspondingly, one end of the sliding groove 13 close to the fractured bone gap 6 is called a proximal end.
Referring to fig. 3 and 4, in the present embodiment, the slider 2 has a substantially block structure, the slider 2 includes two first side surfaces 21 disposed in parallel left and right, two second side surfaces 22 disposed in front and back, and two planes 23 disposed up and down, the slider 2 has a parallelogram structure along a longitudinal section parallel to the second side surfaces 22, and an included angle α between one of the first side surfaces 21 and one plane 23 located below forms an acute angle of the parallelogram, α is 20 ° -70 °, in the present embodiment, α is 45 °. In addition, the slider 2 is provided with a mounting hole 24, the mounting hole 24 is a through hole, and two ends of the mounting hole 24 respectively penetrate through two planes 23 of the slider 2.
The chute 13 is a through chute, and the chute 13 penetrates through two opposite surfaces of the steel plate 1. The chute 13 includes two first cell walls 131 that set up relatively and two second cell walls 132 that set up relatively, two first cell walls 131 set up from top to bottom along the length direction of steel sheet 1, first cell walls 131 and first side 21 looks adaptation, second cell walls 132 and second side 22 looks adaptation, and the size of second cell walls 132 along the length direction of steel sheet 1 is greater than the size of inclined plane 22, thereby can make the second side 22 of slider 2 along the length direction of steel sheet 1 and second cell walls 132 sliding connection, and when slider 2 slides to first side 21 and first cell walls 131 counterbalance, first side 21 can laminate each other with first cell walls 131, thereby increased the area of contact between slider 2 and the chute 13, connection stability has been promoted.

In summary, referring to fig. 1 again, the engagement of the sliding block 2 with the sliding groove 13 of the steel plate 1 and the engagement of the locking member 3 on the broken bone realize the anti-withdrawal function of the sliding block 2 and the locking member 3, that is, when the locking member 3 is about to move along the direction C, the first groove wall 131 of the sliding groove 13 can block the movement trend of the first side 21 of the sliding block 2, so as to avoid easy withdrawal of the sliding block 2 and improve the connection stability.
It can be understood that the specific shape of the sliding block 2 is not limited, and it is only required that the sliding block 2 can slide along the longitudinal direction of the steel plate 1 in a jogged manner, and when the sliding block 2 slides to any position in the chute 13, the orthographic projection part of the steel plate 1 falls on the sliding block 2, so that when the sliding block 2 is driven by the locking piece 3 to move towards the direction C, part of the steel plate 1 can block the sliding block 2 from withdrawing. The orthographic projection direction is the right-to-left projection direction based on the prescribed position in fig. 1. In the present embodiment, the orthographic projection portion of the steel plate 1 falls on the first side surface 21 of the slider 2, so that the slider 2 is prevented from being withdrawn by the abutting action of the first side surface 21 with the steel plate 1.
When the micro-motion locking bone fracture plate is used for connecting the upper bone segment 4 and the lower bone segment 5, the sliding block 2 on the first locking segment 11 can slide downwards or/and the sliding block 2 on the second locking segment 12 can slide upwards under the action of muscle tissue pulling force or body gravity pressurization, so that the upper bone segment 4 and the lower bone segment 5 are mutually close to each other, a section of movable displacement is generated at the bone fracture gap 6, micro-motion stimulation is realized by the movable displacement, and fracture healing is promoted.
In order to enable the micro-motion stimulation, the sliding block 2 on the first locking section 11 is located at the distal end of the corresponding sliding groove 13, or the sliding block 2 on the second locking section 11 is located at the distal end of the corresponding sliding groove 13, or the sliding block 2 on the first locking section 11 and the sliding block 2 on the second locking section 12 are located between the distal end and the proximal end of the corresponding sliding groove 13, and only the condition is met. Meanwhile, a first clearance T1 is formed by the longitudinal distance between the inclined surface 22 of the sliding block 2 on the first locking section 11 and the first groove wall 131 positioned below on the corresponding sliding groove 13, a second clearance T2 is formed by the longitudinal distance between the inclined surface 22 of the sliding block 2 on the second locking section 12 and the first groove wall 131 positioned above on the corresponding sliding groove 13, and the sum of the first clearance T1 and the second clearance T2 forms a micro clearance T which is the size of the movable displacement generated at the broken bone clearance 6. When the device is specifically used, the sliding blocks 2 with different lengths of the second side surface 22 can be replaced, so that the postoperative micro-gap T is preset. The jog gap T is 0.1-0.8mm, in this embodiment, jog gap t=0.25 mm. According to relevant literature and animal clinical verification, when the micro gap T is 0.2-0.5 mm, the fracture healing is facilitated.
According to the micro-motion locking bone fracture plate, when the sliding block 2 is slid to any position in the sliding groove 13, the orthographic projection part of the steel plate 1 can fall on the sliding block 2, so that when the sliding block 2 is to be withdrawn, the sliding block 2 can prop against the steel plate 1, the situation that the sliding block 2 is easy to withdraw is avoided, the connection stability is improved, in addition, the micro-motion stimulation function at the broken bone gap 6 is realized through the sliding action of the sliding block 2 in the sliding groove 13, and the fracture healing is promoted.

The steel plate 1 comprises a first locking section 11 and a second locking section 12 which are connected with each other, wherein the first locking section 11 and the second locking section 12 are sequentially arranged from top to bottom along the length direction (namely the longitudinal direction) of the steel plate 1, the first locking section 11 is correspondingly connected with the upper bone section 4 through a locking piece 3, and the second locking section 12 is correspondingly connected with the lower bone section 5 through the locking piece 3.
In this embodiment, a sliding groove 13 is longitudinally formed in the first locking section 11, a fixing hole 14 is longitudinally formed in the second locking section 12, locking pieces 13 on the first locking section 11 are in one-to-one correspondence with the sliding blocks 2 and detachably connected with the corresponding sliding blocks 2, the locking pieces 13 are slidably connected with the first locking section 11 through the sliding blocks 2, and the locking pieces 3 on the second locking section 12 are detachably and fixedly connected with the fixing hole 14.
