Technical Field

[0001] The utility model relates to the technical field of limb fixing clamps, in particular to an adjustable limb fixing clamp. Background Art

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and poliomyelitis have decreased significantly, while injuries caused by traffic accidents have increased significantly.

[0003] Existing wrist fracture patients need to be pre-fixed during treatment to prevent the patient from moving the arm and causing the injury to worsen. Usually, a splint combined with a bandage is used for fixation. Since the splint fixation requires the arm to be laid flat, and the thickness of the arm varies at different positions, when the fixed arm is laid flat, the wrist will be suspended and passively stressed, which may cause the patient's wrist injury to worsen. For this reason, we provide an adjustable limb fixation clamp. Utility Model Content

[0026] In this embodiment, by setting a threaded rod 22, and with the cooperation of the guide rod 23, the clamp block 24 can be threadedly driven, and then the positions of different clamp blocks 24 can be changed arbitrarily, so that the patient's wrist and forearm can be lifted at the same time and are on the same horizontal plane, so that the patient's wrist does not need to be suspended in the air and passively subjected to force. In addition, a sponge pad 28 is fixedly connected to both clamp block 1 24 and clamp block 2 25. Based on the soft characteristics of the sponge pad 28, the patient's arm can be made more comfortable, and clamp block 25 is slidably connected to the threaded rod 22 and the guide rod 23, so that clamp block 25 can be placed after clamp block 1 24 is adjusted to a suitable position, so as to cooperate with clamp block 1 24 to clamp and fix the patient's wrist and forearm to avoid aggravating the injury due to movement.

[0027] Example 2

[0028] like Figure 1 and Figure 4 As shown, a fixing tube 12 is fixedly connected to the top of the base 11, a sleeve 13 passes through the interior of the fixing tube 12, the sleeve 13 is slidably connected to the fixing tube 12, the sleeve 13 is fixedly connected to the pad 21, bolts 14 pass through the interiors of the fixing tube 12 and the sleeve 13, the bolts 14 are slidably connected to the fixing tube 12 and the sleeve 13, a threaded screw cap 15 is sleeved on the outer surface of the bolt 14, and the threaded screw cap 15 is threadedly connected to the bolt 14.

At this time, the patient's forearm will be placed on the top of another clamping block 24, and the patient's upper arm will be placed on the top of the support block 27. Since the patient's forearm is thicker, the patient's wrist will be suspended and passively exerted at this time, so it can be First, one of the knobs 201 is turned to allow the threaded rod 22 to rotate, and then the clamp block 24 can be threadedly driven with the cooperation of the guide rod 23, so that the clamp block 24 gradually rises, and the patient's wrist is no longer in a suspended and bent state, and can be kept level with the forearm. At this time, if the forearm needs to be fine-tuned, the position of the forearm can be adjusted in the same way until the patient's wrist and forearm are at the same level, and then the clamp block 25 can be passed through the threaded rod 22 and the guide rod 23 at the same time, and the nut 29 can be used to squeeze and fix the clamp block 25 until the patient's wrist and forearm cannot move arbitrarily.
