[0002] The utility model relates to the technical field of surgical fixing clamps, in particular to a hand and foot surgical fixing clamp with a height adjustment function. Background Art

[0003] A hand and foot surgery fixation clamp is a device that fixes or controls the blood vessels of a patient's fingers or toes. When a patient uses nail extraction to treat a nail groove, subungual abscess, subungual blood, onychomycosis, etc., medical staff can use a hand and foot surgery fixation clamp to fix the patient's fingers or toes.

[0004] According to the publication number CN203677458U, a hand and foot surgical fixation clamp belongs to the field of medical equipment technology. It solves the technical problems of low practicability of existing fixation clamps. The fixation clamp includes a rectangular base plate, the upper plate surface of the rectangular base plate is provided with a slide rail, a first clamping block is fixed at the outer end of the slide rail, and a semicircular groove 1 is provided on the first clamping block: a second clamping block is also slidably connected to the slide rail, and a semicircular groove 2 corresponding to the semicircular groove 1 is provided on the second clamping block, and the second clamping block can slide to fit with the first clamping block and combine the semicircular groove 1 and the semicircular groove 2 to form a circular clamping opening: an adjustment seat is also fixed at the inner end of the slide rail, and a screw rod parallel to the slide rail is rotatably arranged on the adjustment seat, a nut is threadedly connected to the screw rod, the nut is fixedly connected to the second clamping block, and the outer end of the screw rod passes through the adjustment seat and is fixedly connected to a handle. The utility model has the advantages of good versatility;

[0005] The above patent mentioned that when the fixing clamp is in use, the patient's toes can be placed between semicircular groove one and semicircular groove two, and the handle is turned to drive the screw to rotate, so that the second clamping block cooperates with the first clamping block to clamp the patient's toes. Since the fixing clamp needs to be prevented from being on a plane when in use, the air suction cup of the fixing clamp is sucked into the plane. At this time, the patient also needs to place the foot on the plane. At this time, there is a certain distance between the toes and the plane. Since the body shapes of each patient are different, the distance between the toes and the plane is different, making the fixing clamp inconvenient to adapt to the toes of different patients. Utility Model Content

[0006] The utility model aims to provide a hand and foot surgical fixation clamp to solve the problem raised in the above-mentioned background technology that the fixation clamp needs to be prevented from being on a plane when in use, and the body shapes of different patients are different, and the distances between toes and the plane are different, making it difficult for the fixation clamp to adapt to the toes of different patients.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hand and foot surgical fixing clamp, comprising a fixing seat and an adjusting mechanism, the upper side of the fixing seat is provided with an adjusting mechanism, and the adjusting mechanism comprises a knob, a threaded column, a placement column, a sliding groove and a first limit frame, the upper side of the fixing seat is movably connected to the knob through a bearing, the upper side of the knob is fixed with a threaded column, and the threaded column is connected to the inner side of the placement column.

[0008] Preferably, a sliding groove is provided on the outer side of the placement column, and the sliding groove is slidably connected to the support rod of the first limiting frame.

[0009] Preferably, a placement seat is fixed on the upper side of the placement column.

[0010] Preferably, the placement column is threadedly connected to the threaded column, and the inner wall spacing of the sliding groove matches the diameter of the first limit frame support rod.

[0011] Preferably, a bidirectional screw rod penetrates the interior of the upper end of the placement column, and the bidirectional screw rod is movably connected to the placement column via a bearing.

[0012] Preferably, both ends of the bidirectional screw rod pass through the limit plates respectively, and a second limit frame is fixed to the lower side of the limit plate.

[0013] Preferably, the placement column is provided with a docking groove above the slide groove, and the docking groove is slidably docked with the second limiting frame.

[0014] Compared with the prior art, the beneficial effects of the utility model are: the hand and foot surgical fixation clamp, by rotating the knob, causes the knob to drive the threaded column to rotate, so that the placement column moves upward along the threaded column, thereby causing the placement column to lift the placement seat upward, so that the groove of the placement seat fits with the patient's toes, and by changing the height of the placement seat, the hand and foot surgical fixation clamp can be easily adapted to the toes of different patients, and by rotating the bidirectional screw, the two limit plates are simultaneously close to squeeze the patient's toes, so that the hand and foot surgical fixation clamp can clamp the patient's toes more quickly.

[0015] 1. When the patient uses nail extraction treatment for diseases such as nail groove, subungual abscess, subungual blood accumulation, and onychomycosis, the hand and foot surgical fixation clamp first places the fixing seat on a flat surface, rotates the knob, and the knob drives the threaded column to rotate, so that the placement column moves up along the threaded column, so that the placement column pushes the placement seat upward, so that the groove of the placement seat fits with the patient's toes. By changing the height of the placement seat, the hand and foot surgical fixation clamp is easy to adapt to the toes of different patients;

[0016] 2. For the hand and foot surgery fixation clamp, after the placement seat is fitted with the patient's toes, the bidirectional screw is rotated so that the two limit plates are simultaneously close to squeeze the patient's toes, so that the hand and foot surgery fixation clamp can clamp the patient's toes more quickly.
