Example 1
The conventional internal fixation system for rib fracture generally adopts a combination of a common strip steel plate and screws or a memory alloy internal fixator to physically fix the rib at the fracture site. The combination of the common strip-shaped steel plate and the screw needs to drill a hole on the rib and then is fixed by the steel plate, and the screw cannot hold the screw because the rib is thin and the drilling depth is too shallow; the drill hole is too deep, and the viscera are easily punctured. The traditional memory alloy internal fixator cannot meet the requirements of the shape of ribs at different parts due to the fact that the traditional memory alloy internal fixator cannot be shaped in an operation, and cannot be pasted during fixation, so that internal fixation falling or rib healing deformity is easily caused.
In order to solve the technical defect that the drilling depth is difficult to control when the internal fixation system combining the common strip-shaped steel plate and the screws is used for fixing the ribs at the fracture part, embodiment 1 provides an internal fixation system 100 for rib fracture, which comprises a support plate 1, a plurality of rib graspers 2 and a plurality of locking screws 3 as shown in fig. 1-5; as shown in fig. 2 to 3, the support plate 1 is in a long strip shape, and a long strip-shaped through hole 10 is formed in the center of the plate surface of the support plate 1; the long edge of the strip-shaped through hole 10 is parallel to the long edge of the support plate 1; the elongated through-hole 10 may serve as a sliding track for sliding the plurality of rib grippers 2 therein, thereby facilitating flexibility in adjusting the position of the rib grippers 2. As shown in FIGS. 4 to 5, the rib grabber 2 comprises a plurality of arc-shaped clamping parts 20 and an intermediate connecting part 21; the paired arc-shaped clamping portions 20 are respectively connected to both sides of the intermediate connecting portion 21; all the arc-shaped clamping parts 20 and the middle connecting part 21 form a channel for accommodating the ribs 001 to pass through; the surface of the rib grabber 2, which is in contact with the rib 001, is arranged in a profiling mode according to the shape of the rib 001, so that the rib grabber 2 can be well attached to the rib to form reliable clamping and fixing. The middle connecting part 21 is provided with a screw through hole 210; as shown in fig. 1, the locking screws 3 respectively pass through the elongated through holes 10 and all the screw through holes 210, and fixedly connect the support plate 1, the plurality of rib grippers 2 and the ribs of the fracture part together; the diameter of the head of the locking screw 3 is larger than the width of the elongated through hole 10. Because the diameter of the head of the locking screw 3 is larger than the width of the elongated through hole 10, the outer edge of the head of the locking screw 3 and the main body part of the support plate 1 are used for forming reliable support, so that the rib grabber 2 and the support plate 1 are reliably fixed; the elongated through hole 10 is suitable for the situation that the plurality of rib graspers 2 are arranged at different positions, thereby facilitating the flexible design of the position arrangement of the plurality of rib graspers 2 according to the actual situation of the rib fracture position and improving the operational flexibility of the internal fixation system 100 for rib fracture. Even when the relative positions of the rib 001, the plurality of rib graspers 2, and the support plate 1 are adjusted during the installation process, the installation failure does not occur due to the positional accuracy, further improving the reliability of the internal fixation system 100 for rib fracture. In addition, because a plurality of technical routes of clamping and fixing the rib grabs 2, supporting the supporting plate 1 to help rib reduction and connecting and fixing the locking screws 3 are adopted, the internal fixing system 100 for rib fracture provided by the embodiment 1 mainly fixes the rib 001 by the following methods: the clamping and fixing of the rib grabber 2 form the circumferential surrounding and fixing of the rib 001, and the supporting plate 1 realizes the relative position fixing of the plurality of rib grabbers 2, and finally forms the reliable fixing with firm locking. The locking screw 3 only plays a role in auxiliary fixation, so that a good rib 001 fixation effect can be achieved without drilling holes in the rib, and the risk of stabbing viscera due to too deep drilling depth of the locking screw 3 is effectively avoided.
In order to overcome the defect that the traditional memory alloy internal fixator cannot be shaped in the operation by the traditional memory alloy steel plate, as shown in fig. 6, the supporting plate 1 can be bent and shaped in the operation according to the actual shape of the rib, so that the connection and fixation of all parts are facilitated, the defect that the traditional memory alloy internal fixator cannot be shaped in the operation by the traditional memory alloy steel plate is overcome, the shape requirements of the ribs at different parts can be met, the ribs can be well attached during fixation, and the incidence rate of falling off or rib healing deformity of the internal fixation system is greatly reduced.
In order to further improve the fixation firmness of the internal fixation system for rib fracture, the internal fixation system 100 for rib fracture provided in example 1 preferably has a length of the locking screw 3 greater than the depth of the screw through hole 210, as shown in fig. 9. It should be noted that the difference between the length of the locking screw 3 and the depth of the screw through hole 210 should be designed in a reasonable interval according to the actual situation, so as to avoid the risk that the drilling depth of the locking screw 3 is too deep to stab the viscera. When the length of the locking screw 3 is slightly greater than the depth of the screw through hole 210, the locking screw 3 not only serves to connect the relative positions of the fixing support plate 1 and the rib grabber 2, but also abuts against the rib 001 to fix the relative positions of the support plate 1, the rib grabber 2 and the rib 001. On the basis that the circumferential surrounding and fixing of the rib 001 and the relative position fixing of the plurality of rib grabhook devices 2 by the supporting plate 1 are formed by clamping and fixing the original rib grabhook devices 2, the supporting plate 1, the fixing between each rib grabhook device 2 and the rib 001 are newly added, the fixing firmness of the internal fixing system for rib fracture is further improved, and the risk that the internal fixing system for rib fracture loosens in the long-term activity process of the rib after the operation of a patient is reduced to a certain extent.
In order to facilitate rapid docking of the rib grasper with the support plate, the internal fixation system 100 for rib fracture provided in embodiment 1 preferably includes, as shown in fig. 4 to 5, 7 and 9, a positioning protrusion 211 on the intermediate connection portion 21; the screw through hole 210 is positioned on the positioning convex part 211; the positioning convex part 211 can be inserted into the elongated through hole 10; the protruding height of the positioning protrusion 211 is smaller than the thickness of the support plate. With the internal fixation system 100 for rib fracture provided in example 1, since the protrusion height of the positioning protrusion 211 is smaller than the thickness of the support plate 1, the locking screw 3 can provide a pressure lock. If the protruding height of the positioning protrusion 211 is greater than or equal to the thickness of the support plate 1, effective pressure fastening may not be achieved, so that the support plate 1, the rib grabber 2 and the rib 001 may not be tightly fixed or even loosened. Through the mutual cooperation of the positioning convex part 211 on the rib gripper 2 and the strip-shaped through hole 10 on the supporting plate 1, the positioning convex part 211 can be rapidly inserted into the strip-shaped through hole 10, so that the rapid positioning and butt joint of the relative position of the rib gripper 2 and the supporting plate 1 are realized, the operation difficulty is greatly reduced, and the time for fixing in the incision and reduction of the surgical operation for rib fracture can be shortened.
In order to provide a support plate more suitable for an internal fixation system for rib fracture, in the internal fixation system 100 for rib fracture provided in embodiment 1, preferably, as shown in fig. 2 to 3, the support plate 1 is made of a medical titanium alloy material.
