The arm and the thigh of the section are guaranteed to be clamped optimally, and the two embedded claw assemblies can clamp optimally.

Description

Technical Field

[0001] The utility model relates to the technical field of fixation inserts for trauma orthopedics, in particular to a conveniently adjustable fixation clamp. Background Art

[0002] Fractures of short tubular bones in the hands and feet often affect the functions of the hands and feet due to malformed fracture healing, joint stiffness, tendon adhesion, etc., especially comminuted fractures have very high requirements for reduction and fixation. Non-surgical treatment is not easy to achieve the reduction requirements. During the treatment process, doctors often use fixation clamps to fix the fracture, and then insert the reduction pin.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0023] Refer to Figure 1-5 , a conveniently adjustable fixed clamp, including two groups of jaw assemblies and a jaw distance adjustment assembly;

[0024] The claw assembly comprises an arcuate panel 3 and an arcuate claw 6 which are symmetrical in both directions. A bolt horizontal plate 32 and a plug horizontal plate 31 are respectively provided at both ends of the arcuate panel 3. A distance adjusting bolt 4 is spirally penetrated at the center of the arcuate panel 3. A connecting block 41 is provided at the center of the upper surface of the arcuate claw 6. The bottom end of the distance adjusting bolt 4 is rotatably installed in the connecting block 41. Two square holes are symmetrically provided at positions near both ends of the arcuate panel 3. A rotating block 52 is provided in the square hole and the two side walls of the rotating block 52 are rotatably installed in the square hole through a first pin 521. An arc adjusting bolt 5 is spirally penetrated on the rotating block 52. A U-shaped block 51 is provided on the upper surface of the arcuate claw 6 near both ends. The arc adjusting bolt 5 is installed in the U-shaped block 51 through a second pin 511.

[0025] The claw pitch adjustment assembly includes a mounting box 1 and multiple sets of pitch adjustment structures, the mounting box 1 is a rectangular box body with one side open, the pitch adjustment structure includes two pitch adjustment blocks 7 and a bidirectional pitch adjustment screw 2, a plurality of bidirectional pitch adjustment screws 2 penetrating the mounting box 1 are arranged at equal intervals on the mounting box 1, the bidirectional pitch adjustment screws 2 are respectively sleeved with a bearing 21 on the inner wall of the mounting box 1 for fixing, two pitch adjustment blocks 7 are inserted into one side of the opening of the mounting box 1, and the pitch adjustment blocks 7 are symmetrically sleeved on the bidirectional pitch adjustment screw 2 from top to bottom, the two pitch adjustment blocks 7 symmetrically penetrate the limit rods 72 on both sides of the bidirectional pitch adjustment screw 2, the side of the pitch adjustment block 7 exposed from the mounting box 1 is provided with a slot 71 for inserting the cross plate 31, and the pitch adjustment block 7 is provided with a locking bolt 711 that can be screwed into the slot 71;

[0026] The bolt cross plate 32 is provided with bolt holes, and the bolt cross plate 32 on the upper and lower symmetrical bow-shaped panel 3 is fixed by being installed at the bolt hole position with bolts 8 and nuts 81.

[0027] According to the degree of arm and thigh fracture and the fracture position, determine the distance between the two claw assemblies to achieve a better clamping effect (the general fixed claw assembly has a fixed distance between the two). First, place the two sets of claw assemblies in the clamping position, insert the plug-in horizontal plate 31 on the right side of the bow panel 3 into the slot 71 and lock it with the locking bolt 711. By rotating the top position of the two-way pitch adjustment screw 2, move the two pitch adjustment blocks 7 relative to each other to achieve mutual clamping of the bow panel 3. It is enough to almost touch the skin. Then fix the bolt horizontal plate 32 on the other side with bolts 8 and nuts 81. At this time, use the pitch adjustment bolt 4 to adjust the bow claw 6 to make it fit tightly in the clamping position (clamping in the middle position), and then by rotating the arc adjustment bolt 5, push the two ends of the bow claw 6 inward to clamp, ensuring that the bow claw 6 can fit and clamp as a whole, and the clamping effect is best.

[0028] The arcs of the arcuate panel 3 and the arcuate claw 6 are both between 120 and 135 degrees, and the arcuate claw 6 is adjusted and squeezed by the arc adjustment bolt 5 to form an arc fluctuation range of 0-45 degrees. Since the arcuate panel 3 needs to have a certain vertical movement distance, the arcuate is not easy to reach 180 degrees, and the maximum clamping degree of the arcuate claw 6 is to achieve splicing between the two, that is, to form a circle, but the arcuate claw 6 has a maximum of 135 degrees, so the maximum bending arc is 45 degrees.

[0029] The inner surface of the arched claw 6 is wrapped with a latex sponge layer, so the clamping is more comfortable.

[0030] The number of the distance adjustment structures is not less than 4 in the installation box 1, and the width of the distance adjustment block 7 is 5-8 cm. It is ensured that 1-2 distance adjustment structures can be maintained between the two sets of claw assemblies, which is equivalent to a spacing of no more than 20 cm, and the minimum spacing is 5-10 cm.

[0031] The width of the arcuate panel 3 is 3-5 cm, and the length of the arcuate panel 3 that is smaller than the width of the distance adjusting block 7 is not greater than 2 cm. The plug-in cross plate 31 can be inserted into the distance adjusting block 7, but cannot be too narrow, and the width is determined according to actual conditions.

[0032] The bolts 8 at the upper and lower surfaces of the bolt transverse plates 32 on the two arched panels 3 are respectively covered with a nut 81. It can not only play a role in connection and fixing, but also limit the bolt transverse plates 32 from shaking.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
