[0001] The utility model relates to the technical field of a locking temporary fixator, in particular to a locking temporary fixator used for intraoperative fracture reduction. Background Art

[0002] Fracture reduction is the first step in fracture treatment, which aims to realign the broken and displaced bones to restore the supporting function of the bones. After reduction, the better the fracture alignment, the faster the fracture heals. In order to achieve a stable reduction effect, appropriate fixation methods need to be used.

[0003] Most of the fixators on the market require hand-held nail-holding compression forceps during use, which may block the field of view of the surgical area. Therefore, a locking temporary fixator is needed for intraoperative fracture reduction. Utility Model Content

[0004] The utility model aims to provide a locking temporary fixator for intraoperative fracture reduction, which solves the problem that most of the fixators in the prior art use hand-held nail-holding pressure forceps during use, resulting in obstruction of the field of view of the surgical area.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solutions: a locking temporary fixator for intraoperative fracture reduction, comprising a first support frame and a preparation mechanism installed on the side of the first support frame, wherein the preparation mechanism comprises a fixing assembly;

[0006] The fixing assembly includes a first supporting frame having a top wall fixedly connected to a fixing hook, the fixing hook is provided with a screw, the side wall of the first supporting frame is fixedly arranged with a forward tooth plate, one side of the forward tooth plate is meshedly connected to a reverse tooth plate, the other side of the reverse tooth plate is fixedly connected to a second supporting frame, and the upper side wall of the first supporting frame is fixed with a fixing plate.

[0007] Preferably, a semicircular gusset plate is fixed to the inner side wall of the second supporting frame, and two groups of semicircular gusset plates are provided and are symmetrically distributed about the center line of the second supporting frame.

[0008] Preferably, the outer wall of the first support frame is fixedly connected with a hollow plate, a limiting slide rail is provided on the inner side of the hollow plate, a limiting slider is slidably connected to the inner side of the limiting slide rail, and a trapezoidal baffle is fixed above the limiting slider.

[0009] Preferably, a push plate is fixed above the trapezoidal baffle, a damper is provided on the side wall of the trapezoidal baffle, and a spring is provided on the periphery of the damper.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The locking temporary fixator for intraoperative fracture reduction is provided with a lateral tooth plate and a lateral tooth plate. The first support frame and the second support frame can be fixed by screws. Then, the two sets of fixing plates are pressed by external force to move relative to each other, so that the two ends of the bone fracture can be merged. The lateral tooth plate and the lateral tooth plate can be set to merge the two ends of the bone fracture and then fix them, and then proceed to the next step. For obese patients or patients with deep fracture ends, the device can replace the handheld pressure clamp for merging and fixing, avoiding the use of handheld nail holding pressure clamps in most cases during the use of the fixator, resulting in the obstruction of the field of view of the surgical area.

[0012] 2. The locking temporary fixator used for intraoperative fracture reduction is provided with a damper and a spring. The first support frame is first fixed by screws, and then a suitable position can be selected to directly press the second support frame from the upper side of the first support frame. The pressing force will cause the trapezoidal baffle to slide to both sides through the limiting slide rail and the limiting slider, so that the second support frame can be directly engaged with the inner side of the first support frame, and the trapezoidal baffle will automatically restore through the damper and the spring, and the second support frame will be engaged with the inner side of the first support frame, so as to prevent the second support frame and the first support frame from being misaligned when they are relatively merged, thereby increasing the practicality of the device.
