Description

Technical Field

[0001] The utility model relates to the field of reset fixing devices, in particular to a temporary reset fixing device during traumatic fracture surgery. Background Technique

[0002] Traumatic fracture refers to an injury in which the integrity and continuity of the bone are damaged due to external forces. Such injuries are usually related to external force factors such as accidental falls, accidental impacts, and traffic accidents. Traumatic fracture surgery is an orthopedic surgery used to treat fractures caused by trauma. The goal of such surgeries is to restore the normal anatomical structure and function of the bone, promote fracture healing, and minimize the patient's pain and recovery period.

[0003] During the surgery for traumatic fractures, a temporary reset fixing device is required. The existing temporary reset fixing devices generally have a three-claw structure, where two hinged connecting plates are respectively connected to a clamping claw and two clamping claws. This type of temporary reset fixing device has certain drawbacks when in use. Since the distance between the two clamping claws is not adjustable, its use has relatively large limitations.

[0004] Therefore, it is necessary to provide a new temporary reset fixing device during traumatic fracture surgery to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a temporary reset fixing device during traumatic fracture surgery.

[0006] The temporary reset fixing device during traumatic fracture surgery provided by the utility model includes a first connecting plate and a second connecting plate. The first connecting plate and the second connecting plate are hinged to each other. At one end of the first connecting plate and the second connecting plate close to the hinge point, a telescopic member is fixedly installed. A backing plate is fixedly installed on the telescopic member of the first connecting plate, and a receiving plate is fixedly installed on the telescopic member of the second connecting plate. Clamping claws are connected to both sides of the receiving plate through moving members.

[0007] The moving member includes a threaded rod and a guide rod. The threaded rod is threadedly connected to a through hole formed in the receiving plate. The threaded rod is rotationally connected to the clamping claw through a bearing. One end of the threaded rod is fixedly installed with a rotating plate, and a cross-shaped groove is formed in the rotating plate. A counterbore for placing the rotating plate is formed in the clamping claw. One end of the guide rod is fixedly installed on the clamping claw, and the other end of the guide rod is movably arranged in the through hole formed in the receiving plate.

[0008] Preferably, the telescopic member includes a movable plate and a sleeve. One end of the movable plate is movably arranged inside the sleeve. A plurality of adjusting holes are formed in the movable plate. A countersunk screw is threadedly connected to the sleeve, and one end of the countersunk screw can be inserted into the adjusting hole.

[0009] Preferably, a baffle is fixedly installed on the first connecting plate. When the first connecting plate and the second connecting plate are flush, the second connecting plate is in contact with the baffle.

[0010] Preferably, a guiding arc plate is fixedly installed on the second connecting plate, and the guiding arc plate is movably inserted into a notch formed in a side wall of the first connecting plate.

[0011] Preferably, a triangular block is fixedly installed on the guiding arc plate. The triangular block has an isosceles triangular prism structure, and a limiting member for limiting the triangular block is fixedly installed on the first connecting plate.

[0012] Preferably, the limiting member includes a mounting bracket, a spring, and a limiting block. The mounting bracket is fixedly installed on the first connecting plate. A limiting block is movably arranged in a groove formed in a side wall of the mounting bracket. One end of the limiting block extending outside the groove of the mounting bracket has an isosceles triangular prism structure. Two ends of the spring are respectively fixedly connected to the bottom wall of the groove of the mounting bracket and the limiting block.

[0013] Compared with the related art, the temporary reduction and fixation device for intraoperative traumatic fractures provided by the present utility model has the following beneficial effects:

[0014] 1. Adjust the distance between the two jaws according to the specification of the steel plate. Place the screwdriver in the cross-shaped groove of the rotating plate, and rotate the screwdriver to drive the rotating plate to drive the threaded rod to rotate. The threaded rod screws in or out in the through hole of the receiving plate. Due to the arranged guiding rod, the distance between the jaw and the receiving plate changes, thereby realizing the adjustment of the distance between the two jaws.

[0015] 2. Rotate the first connecting plate and the second connecting plate. When the triangular block rotates to the position of the limiting block, the inclined surface of the isosceles triangular prism structure of the limiting block is squeezed, so that the limiting block moves into the groove of the mounting bracket, and the spring is compressed. When the triangular block moves past, the limiting block resets under the action of the spring. At this time, the second connecting plate is in contact with the baffle. Under the action of the spring, the second connecting plate is limited, so that the second connecting plate is not easily separated from the first connecting plate without external force, which is convenient for the storage work.
