Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically a calcaneal fracture reduction auxiliary device. Background Technology
[0002] Calcaneal fractures are a common type of foot fracture, requiring reduction during treatment. Manual reduction demands high physical strength from the practitioner and can easily injure their lower back; therefore, a calcaneal reduction frame is used. The frame has a step connected to the base by a ramp. During calcaneal fracture reduction, the affected limb is placed on the frame for manipulation. Specifically, the patient lies prone with the knee flexed and the ankle plantarflexed. The affected limb is placed on the frame, with the dorsum of the foot on the step and the lower leg on the ramp. One practitioner holds the upper part of the lower leg to counteract traction, while another practitioner grasps the heel and applies force along the plantar axis to correct the misalignment of the calcaneus. Sometimes, manual reduction on a calcaneal reduction frame may not provide sufficient traction on the calcaneal tuberosity. Therefore, using an auxiliary rope, which is wrapped around the proximal end of the calcaneal tuberosity and placed in front of the metatarsophalangeal joint for counter-traction, is more reliable than the doctor holding the upper part of the lower leg of the affected limb for counter-traction. However, it is necessary to prevent the auxiliary rope from cutting the skin of the heel, and the traction direction must be controlled within the edge of the sole of the foot, otherwise there is a risk of tearing of the fat pad of the heel.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0025] Please see Figure 1 As shown, this embodiment provides an auxiliary device for calcaneal fracture reduction, including two symmetrically arranged clamps 3, which are movably connected by a connector 2. The two clamps 3 can rotate relative to each other, realizing the opening and closing of the two clamps 3. A push handle 1 is also fixedly connected to the connector 2. The clamps 3 include a clamping body 31, a contraction bow 32, and a pull handle 33. One end of the contraction bow 32 is connected to the clamping body 31, and the other end is connected to the pull handle 33.
[0026] This utility model can be used in conjunction with the calcaneal reduction frame 4. Please refer to the structure of the calcaneal reduction frame 4. Figure 7 As shown, the patient lies prone with knees flexed and ankles plantarflexed, allowing the gastrocnemius muscles to relax, which is conducive to reduction. The affected limb is placed on the calcaneal reduction frame 4, with the dorsum of the foot on the step 41 and the lower leg on the ramp 42. The two clamps 3 are opened, and the calcaneal fracture reduction auxiliary device is slipped onto the foot from the heel end, with the clamps 31 parallel to the edge of the sole, not higher than the edge. One practitioner grips the push handle 1 with both hands, bringing the ends of the clamps 31 against the heel, while another practitioner grips the pull handle 33 with both hands, clamping the clamps 31 from both sides. Both practitioners simultaneously push, pull, squeeze, shake, and impact, constantly paying attention to the force and direction to reduce the fracture. The calcaneal fracture reduction auxiliary device integrates multiple techniques such as pushing, traction, clamping, shaking, and squeezing, concentrating force, saving effort and time, being easy to operate, achieving good reduction results, and preventing secondary injury to the affected limb. It should be noted that the limb bearing surfaces of the calcaneal reduction frame 4, such as the step 41 and the ramp 42, need to be padded with flexible materials. Soft materials such as cotton or silicone can be padded on the step 41 and the ramp 42, and bandages can be wrapped around them to prevent injury to the knee or anterior tibial tissues during reduction.
[0027] In some embodiments, please refer to Figure 2-6 As shown, the connector 2 includes a first connecting part 21, a second connecting part 22, and a shaft. The first connecting part 21 and the second connecting part 22 have through holes in their centers. The shaft passes through the through holes of the first connecting part 21 and the second connecting part 22 in sequence, and is limited at both ends of the shaft to prevent the first connecting part 21 and the second connecting part 22 from coming off the shaft. The first connecting part 21 and the second connecting part 22 can rotate around the shaft, so that the two clamps 3 can be opened and closed freely.
[0028] Furthermore, the first connecting part 21 is fixedly connected to the clamping body 31 end of one of the clamping bodies 3. The clamping body 31 is connected to the outer side of the first connecting part 21 and located on the side close to the second connecting part 22. The clamping body 31 end of the other clamping body 3 is fixedly connected to the outer side of the second connecting part 22. When the first connecting part 21 and the second connecting part 22 are stacked and hinged by a shaft, the two clamping bodies 3 are located on the same plane. The clamping body 31 end is arc-shaped, and the two arc-shaped ends cooperate to form a semi-circular or near-semi-circular shape, which is just right for placing the heel and avoids local stress imbalance on the heel during traction.
[0029] Furthermore, the push handle 1 is fixed to the outer side of the first connecting part 21 or the second connecting part 22, and the push handle 1 and the clamp body 3 are located on opposite sides.
[0030] Furthermore, the contraction bow 32 is located on the side of the clamping body 31 opposite to the other clamping body 31, and the contraction bow 32 bends toward the pushing handle 1, while the pulling handle 33 extends toward the side opposite to the center of the contraction bow 32. The design of the contraction bow 32 can buffer and disperse the force exerted by the doctor, preventing deformation of the clamping body 31.
[0031] It should be noted that the outer surfaces of the push handle 1, clamp body 31, and pull handle 33 are covered with flexible material, which can increase friction, prevent slippage, and protect the skin. The push handle 1, clamp body 31, and pull handle 33 can be directly covered with a silicone sleeve, or they can be padded with cotton or silicone and wrapped with bandages.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
