The embodiments described below are only part of the embodiments of the device, rather than all the embodiments. Based on the embodiments of the device, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the device.
[0026] Please refer to Figure 1 The device provides a rapid reduction and auxiliary fixation guide device for internal malleolus fracture, and the technical solutions are as follows:
[0027] A quick reduction, auxiliary fixation guide device for medial malleolus fracture, comprising a first large forceps handle 1 and a second large forceps handle 2 hinged to each other, and a small forceps handle 3, wherein a hollow block 4 is installed at the hinge of the first large forceps handle 1 and the second large forceps handle 2, the small forceps handle 3 is connected with the hollow block 4, one end of the small forceps handle 3 is provided with a small hook 31, an angle-adjusting fixing hole 32 is formed at the end of the small forceps handle 3 close to the small hook 31, a small finger ring 33 is installed at the other end of the small forceps handle 3, and an adjusting nut 5 for fixing and loosening the small forceps handle 3 is spirally installed on the upper surface of the hollow block 4.
[0028] Before the operation starts, the medical staff needs to prepare the quick reduction, auxiliary fixation guide device for medial malleolus fracture, which is composed of a first large forceps handle 1 and a second large forceps handle 2 connected by hinge. Ensure that the first large hook 11, the second large hook 21 and the small hook 31 of the guide device are in good working condition, and check whether the first guide hole 12, the second guide hole 22 and the fixing hole 32 are unobstructed, so that the drill and the Kirschner wire and other locking parts can pass through smoothly.
[0029] Through the design of the first large forceps handle 1 and the second large forceps handle 2 hinged to each other, the angle of the two large forceps handles can be flexibly adjusted to adapt to different patient's medial malleolus fracture conditions. The small hook 31 can further hook the fracture block to provide additional stability and prevent the fracture from shifting again. This auxiliary fixation helps the healing and rehabilitation process of the fracture. The several fixing holes 32 formed on the side of the small hook 31 are used to adapt to the fracture blocks at different positions, and also play a guiding role for fixed parts such as Kirschner wire or compression screw. The small finger ring 33 on the small forceps handle 3 can move the small forceps handle 3 to the appropriate position, and the adjusting nut 5 can be tightened after the small forceps handle 3 is moved to the appropriate position, so that the small forceps handle 3 and the second large forceps handle 2 are fixed. After the operation is completed, the adjusting nut 5 can also be loosened, so that the small forceps handle 3 can be moved to facilitate cleaning and disinfection.
[0030] One end of the first large forceps handle 1 is provided with a first large hook 11, and a first guide hole 12 is formed at the end close to the first large hook 11. The other end of the first large forceps handle 1 is provided with a first large finger ring 13.
[0031] Through the large hook on the large forceps handle, the fracture block can be clamped. There are multiple guide holes beside the large hook, which can ensure the alignment of the drill and the guide hole, so as to accurately drill into the tibia,
[0032] One end of the second large forceps handle 2 is provided with a second large hook 21, and a second guide hole 22 is formed at the end close to the second large forceps handle 2. The other end of the second large forceps handle 2 is provided with a second large finger ring 23.
[0033] During the operation, first gently clamp the claws 3 on both sides of the guide on the medial malleolus fracture block. At this time, medical staff need to ensure that the two sides of the claw 3 can be closely attached to the fracture block, so as to effectively fix in the subsequent operation. This step needs medical staff to adjust the opening and closing degree of the clamp handle according to the specific situation of the patient, so as to ensure the stability of clamping. Through the large claw on the large clamp handle, the fracture block can be clamped, and there are multiple guide holes beside the large claw, which can ensure the alignment of the drill bit and the guide hole, so as to accurately drill into the tibia. After drilling, medical staff can use kirschner wire or compression screw to fix the medial malleolus fracture block on the tibia, creating conditions for further strong internal fixation.
[0034] The small clamp handle 3 is located at the central axis position of the first large finger ring 13 and the second large finger ring 23.
[0035] The small clamp handle 3 is located at the central axis position, passing through the upper and lower ends of the hollow block 4. By pulling the small finger ring 33, the position of the small clamp handle 3 can be controlled. By rotating the small finger ring 33 and the small clamp handle 3, the direction of the small claw 31 can be adjusted.
[0036] After clamping the fracture block, medical staff need to carefully observe the contact between the fracture block and the tibia to ensure that the fracture block is closely attached to the tibia and meets the requirements of anatomical reduction. At this time, medical staff can rotate the small clamp handle 3 to the appropriate position to further adjust the clamping angle of the small claw 31, so as to ensure the accurate positioning of the fracture block.
[0037] The long rod part of the small clamp handle 3 is cylindrical.
[0038] The long rod is designed in a cylindrical shape, which is convenient for rotating the small clamp handle 3 and fixing the adjusting nut 5. After the fracture block and the tibia are anatomically reduced, medical staff need to pull the small finger ring 33 of the small clamp handle 3, so that the small claw 31 on the small clamp handle 3 hooks the tibia. At this time, attention should be paid to maintaining the clamping force of the first large claw 11 and the second large claw 21 to prevent displacement of the fracture block during the fixing process. Then, medical staff should tighten the adjusting nut 5 to ensure the stability of the connection between the small clamp handle 3 and the first large clamp handle 1 and the second large clamp handle 2, and further enhance the clamping effect.
[0039] The second large clamp handle 2 is installed with an opening and closing lock 24, which is located above the first large clamp handle 1 and is connected with it.
[0040] The opening and closing lock 24 has several protrusions, which can be connected with the lock hole on the first large clamp handle 1, and can be adjusted in angle to adapt to the differences of different human bodies, and has stronger practicality.
[0041] After the operation is completed, medical staff need to check the use of the guide to ensure that all parts are working normally, and observe the recovery of the patient. If necessary, imaging examination can be performed to confirm the fixation effect of the fracture block.
[0042] Through the above-mentioned embodiments, the medial malleolus fracture reduction and fixation guide device of the present application can effectively improve the accuracy and efficiency of the operation, reduce the risk of operation failure and postoperative complications, and ensure the safety and health of the patient. The design of the guide fully considers the individual differences of patients, enhances its adaptability in various clinical situations, and thus improves the overall operation efficiency and success rate.
[0043] Working principle: the first large hook claw 11 and the second large hook claw 21 clamp the medial malleolus fracture block from the side, after the fracture block is tightly attached to the tibia and anatomically reduced, the small clamp handle 3 is rotated to the appropriate position, then the small finger ring 33 on the small clamp handle 3 is pulled, the small hook claw 31 hooks the medial malleolus fracture block, then the adjusting nut 5 is tightened, at this time the first large hook claw 11, the second large hook claw 21 and the small hook claw 31 force the medial malleolus fracture block to be tightly attached to the tibia, finally, the Kirschner wire or gap screw is used to fix the medial malleolus fracture block on the tibia, creating conditions for further rigid internal fixation.
[0044] The embodiments of the present application have been shown and described, and various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
