Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a postoperative nursing device for patients with deep vein thrombosis of the lower limbs during vascular surgery. Background Art

[0002] During vascular surgery on patients with lower limb thrombosis, a support device is usually required to support the leg. A distraction device is then used to distract the affected part of the leg to facilitate the surgical procedure. Chinese Patent Publication No. CN214017649U discloses a clinical distraction device for foot and ankle surgery, comprising a base, a support frame, an adjustment rod, a distraction device, and an illumination device. The top of the base is fixedly connected to the support frame. Adjustment rods are mounted on both sides of the support frame. The top of the adjustment rod is fixedly connected to an adapter block. The adapter block is detachably connected to a threaded rod via an internal thread groove. One end of the threaded rod is fixedly connected to the distraction device. The top of the adapter block is fixedly connected to a rotating shaft, which is movably connected to the illumination device. The device has the advantages of stably and efficiently supporting and distracting the patient's affected part. The degree of distraction can be adjusted according to the patient's ankle and surgical needs to reveal the surgical field, alleviating the patient's pain during surgery. The illumination device can also illuminate the patient's affected part, facilitating surgery for medical staff and significantly improving work efficiency.

[0003] In the above technical solution, although the leg stretching device can stretch the affected part of the leg to facilitate surgery, the leg support device usually only has a simple support frame for placing the legs, and there is no fixing device to fix the legs. After the patient's legs are stretched by the stretching device, the patient is at risk of displacement or tearing of the stretched position due to pain or when accidentally moving the body, which is not conducive to the progress of the operation and postoperative recovery. In addition, since the patient's affected part is often accompanied by swelling, the existing medical clamping device is not convenient to use and the effect is not good. For this reason, a postoperative care device for patients with deep vein thrombosis of the lower limbs in vascular surgery is proposed. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In response to the deficiencies in the prior art, the present invention provides a postoperative care device for patients with deep vein thrombosis in the lower limbs undergoing vascular surgery. The device has the advantages of achieving stable clamping and fixation, preventing the patient's movement from causing displacement or tearing of the support position, and facilitating the progress of the surgical procedure. It solves the problem that the leg support device usually only has a simple support frame for placing the legs, and there is no fixing device to fix the legs. After the patient's legs are stretched by the stretching device, the patient is at risk of causing displacement or tearing of the support position due to pain or when accidentally moving the body, which is not conducive to the progress of the surgical procedure and postoperative recovery. In addition, since the patient's affected area is often accompanied by swelling, the existing medical clamping device is not convenient to use and the effect is poor.

[0032] Specifically, a threaded hole 305 is provided on the sliding block 304, and the threaded rod 301 is threadedly installed in the threaded hole 305.

The through hole 306 facilitates the rotation of the threaded rod 301 when the screw block 302 is rotated. The limiting hole 307 prevents the threaded rod 301 from detaching from the placement plate 1 during rotation, thereby increasing the rotation stability of the threaded rod 301.

[0034] Specifically, the pre-fixing mechanism 4 includes a fixed shaft 401, which is mounted on the placement frame 308, a semicircular ring 402 is rotatably mounted on the fixed shaft 401, a locking hole 403 is opened on the semicircular ring 402, an arc end locking shaft 404 is movably mounted in the locking hole 403, the arc end locking shaft 404 is slidably mounted on the placement frame 308, and a limited block 405 is installed on the arc end locking shaft 404, wherein the pre-fixing mechanism 4 refers to the semicircular ring 402 on the fixed shaft 401. The rotation causes the semicircular ring 402 and the placement frame 308 to close and form a frame to pre-fix the limb. When the semicircular ring 402 rotates to contact the arc end locking shaft 404, it continues to slide and squeeze the arc end of the arc end locking shaft 404, driving the arc end locking shaft 404 to slide on the placement frame 308 and stretch the compression spring 406. When the locking hole 403 coincides with the arc end locking shaft 404, the arc end locking shaft 404 is driven to fall into the locking hole 403 under the resetting action of the compression spring 406, completing the pre-fixation of the structure.

[0035] Specifically, a rotation hole 408 is opened on the semicircular ring 402 , and the fixed shaft 401 is rotatably installed in the rotation hole 408 . The rotation hole 408 limits the movement of the fixed shaft 401 , and the fixed shaft 401 can and can only rotate in the rotation hole 408 .

Through the setting of the compression spring 406, when the locking hole 403 and the arc end locking shaft 404 coincide with each other, the arc end locking shaft 404 is driven to fall into the locking hole 403 under the resetting action of the compression spring 406, thereby completing the pre-fixation of the structure.

[0037] Specifically, a torsion spring 407 is sleeved on the fixed shaft 401, and the torsion spring 407 is installed on the semicircular ring 402. Through the setting of the torsion spring 407, when the limit block 405 is pulled to make the arc end locking shaft 404 disengage from the locking hole 403, the semicircular ring 402 is automatically driven to open under the resetting action of the torsion spring 407, thereby increasing the degree of automation and convenient use of the structure.

[0038] Specifically, the adaptation mechanism 5 includes a telescopic shaft 501, which is slidably mounted on the semicircular ring 402. A stop block 502 is mounted on one end of the telescopic shaft 501, and the stop block 502 contacts the semicircular ring 402. An arc-end rubber plate 503 is mounted on the other end of the telescopic shaft 501. A return spring 504 is movably sleeved on the telescopic shaft 501, and one end of the return spring 504 is mounted on the semicircular ring 402, and the other end of the return spring 504 is mounted on the arc-end rubber plate 503. The adaptation mechanism 5 refers to driving the arc-end rubber plate 503 on the telescopic shaft 501 to contact the limb during the pre-fixation process of the semicircular ring 402 and driving the telescopic shaft 501 to slide on the semicircular ring 402 to compress the return spring 504.

[0039] Specifically, a telescopic hole 505 is opened on the semicircular ring 402 , and the telescopic shaft 501 is slidably installed in the telescopic hole 505 . The telescopic hole 505 limits the movement of the telescopic shaft 501 , and the telescopic shaft 501 can only slide in the telescopic hole 505 .

[0040] During use, the adjusting mechanism 3 is adjusted according to the swollen part of the patient's limb, so that the pre-fixing mechanism 4 is located at the normal limbs on both sides for pre-fixation, and the adapting mechanism 5 is used to adapt and press the different limb parts of different patients to complete the fixation of the limb, thereby preventing the limb from being accidentally moved after the expansion device 2 expands the affected part, causing the expanded part to tear or move, and ensuring the normal progress of the surgical process. The adjusting mechanism 3 refers to rotating the screw block 302 to drive the threaded rod 301 to rotate on the placement plate 1, thereby driving the sliding block 304 to move between the threaded hole 305 and the placement plate 1. The sliding grooves on the plate 1 limit the sliding of the plates 308, thereby driving the placement racks 308 to slide closer to or farther from each other, making it convenient for the placement racks 308 to be placed on the healthy limbs on both sides of the affected area and fixed. The through holes 306 facilitate the rotation of the threaded rod 301 when the screw block 302 is rotated, and the limiting holes 307 prevent the threaded rod 301 from detaching from the placement plate 1 when rotating, thereby increasing the rotation stability of the threaded rod 301. The pre-fixing mechanism 4 refers to the semi-circular ring 402 rotating on the fixed shaft 401 so that the semi-circular ring 402 and the placement rack 308 are closed. The frame is used to pre-fix the limb. When the semicircular ring 402 rotates to contact the arc end locking shaft 404, it continues to slide and squeeze the arc end of the arc end locking shaft 404, driving the arc end locking shaft 404 to slide on the placement frame 308 and stretching the compression spring 406. When the locking hole 403 and the arc end locking shaft 404 coincide with each other, the arc end locking shaft 404 is driven to fall into the locking hole 403 under the reset action of the compression spring 406, completing the pre-fixation of the structure. By setting the torsion spring 407, it is achieved that when the limit block 405 is pulled to make the arc end locking shaft 404 disengage from the locking hole 403, the torsion spring 407 is reset. Under the action, the semicircular ring 402 is automatically driven to open, which increases the degree of automation and convenient use of the structure. The adaptation mechanism 5 refers to the arc-end rubber plate 503 on the telescopic shaft 501 that drives the telescopic shaft 501 to contact the limb during the pre-fixation process of the semicircular ring 402 and drives the telescopic shaft 501 to slide on the semicircular ring 402 to compress the return spring 504. The elastic force of the return spring 504 facilitates the clamping and pressing of limbs of different sizes, thereby improving the wide applicability of the structure. The telescopic hole 505 limits the movement of the telescopic shaft 501, and the telescopic shaft 501 can only slide in the telescopic hole 505.
