Description

Technical Field

[0001] The utility model belongs to the technical field of body position pads, and in particular relates to a body position pad for great saphenous vein removal in bypass surgery. Background Art

[0002] The great saphenous vein in the leg is one of the most commonly used "bridge" blood vessel materials in coronary artery bypass surgery. The great saphenous vein extends from the ankle to the base of the thigh and is the longest superficial vein in the human body. It has a small curvature and a blood vessel caliber that matches the coronary artery, making it a good bridge blood vessel material. Immediately after the bypass surgery to remove the great saphenous vein, there will be obvious swelling in the lower limbs. This is because the human body's lower limbs have two sets of venous return systems, the deep veins and the superficial veins. Removing the great saphenous vein for bypass surgery will inevitably cause venous return obstruction and swelling of the lower limbs.

[0003] For lower limb swelling, patients need to raise their lower limbs by about 30 degrees when lying in bed in the early stage of surgery, or use medical elastic stockings, put them on when walking on the ground, and take them off after lying in bed to avoid wearing them for a long time. Both methods can promote venous return in the lower limbs, reduce lower limb swelling, and promote wound healing.

[0004] In fact, the popliteal fossa of the lower limbs also needs to be padded, which can effectively prevent nerve damage. However, the inventor searched many patents and found that this innovation was not disclosed or disclosed. For example, patent announcement number CN208525290U, a lower limb lifting pad for post-coronary artery bypass grafting surgery, solves the problem of the foot, and ensures the comfort of the patient's foot through an electric push rod at the foot. Summary of the invention

[0005] The utility model aims to design a body position pad for obtaining the great saphenous vein during bypass surgery. The utility model has a simple overall structure and is easy to use. It not only has the function of elevating the lower limbs, but also can cushion the popliteal fossa of the lower limbs.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A body position pad for obtaining the great saphenous vein during bypass surgery, the body position pad comprising a pad plate, a popliteal pad being arranged in the middle of the pad plate, the popliteal pad being movable forward and backward along the pad plate, a heel placement area being arranged at the foot of the pad plate, a retractable support mechanism being installed on the rear lower surface of the pad plate for adjusting the inclination of the pad plate, and a fixing belt being added at the rear of the pad plate.

[0008] Furthermore, a groove is provided in the middle of the pad, and the shape of the groove corresponds to the shape of the lower limb.

[0009] Furthermore, sliding grooves are provided on both sides of the pad, and a protruding slider is correspondingly provided at the bottom of the popliteal pad. The slider on the popliteal pad slides in the sliding groove. The purpose of sliding is to make adaptive adjustments according to the length of the lower limbs of different patients, so that the lower limbs of the patients are in a more comfortable state.

[0010] Furthermore, the popliteal fossa pad is in an arc shape, which serves to slightly raise the popliteal fossa and prevent the popliteal fossa from being suspended in the air, which can help prevent nerve damage.

[0011] Furthermore, the heel placement area is in a groove shape, and the groove shape mimics the shape of a heel.

[0012] Furthermore, the retractable support mechanism comprises a fixed plate, and the fixed plate is hinged to the rear of the pad via a retractable oil cylinder, so that the inclination of the pad can be adjusted.

[0013] The following beneficial effects can be obtained through the above technical solution:

[0014] The overall structure of the utility model is suitable for being placed at the end of the bed. On the one hand, the patient can adjust the position of the popliteal fossa pad according to the actual length of the lower limbs, so that the different lengths of the heel and the popliteal fossa of different patients can be appropriately adjusted, thereby improving the adaptability of the entire product to different patients, and making it flexible to use and widely used. On the other hand, the popliteal fossa pad of the lower limb can effectively prevent nerve damage.

[0015] The utility model has a basic angle adjustment function, and the inclination can be between 20 and 40 degrees. For use in surgery or other situations, a fixing belt is added at the tail, and the fixing belt can be tied to the end of the bed, which can also be lifted.

[0016] The bionic lower limb groove in the middle of the pad allows the patient's lower limbs to be comfortable and accurately placed without swinging left or right, and has a limiting function. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-4 As shown, a position pad for obtaining the great saphenous vein during bypass surgery, the position pad comprises a pad 1, a popliteal pad 4 is arranged in the middle of the pad 1, the popliteal pad 4 is in an arc shape, and serves to slightly raise the popliteal fossa to prevent the popliteal fossa from being suspended in the air, the popliteal pad can move forward and backward along the pad 1, and its specific structure is that sliding grooves 3 are arranged on both sides of the pad 1, and a protruding slider 5 is arranged at the bottom of the popliteal pad 4, and the slider 5 on the popliteal pad 4 slides in the sliding groove 3, a heel placement area 6 is arranged at the foot of the pad 1, and a retractable support mechanism is installed on the rear lower surface of the pad 1 to adjust the inclination of the pad, and a fixing belt 7 is added to the rear of the pad 1. A groove 2 is arranged in the middle of the pad 1, and the groove 2 is bionic in shape of the lower limbs, which is convenient for the placement of the affected limb and also serves as a limit function to prevent left and right shaking. The retractable support mechanism comprises a fixed plate 8, and the fixed plate is hinged to the rear of the pad 1 through a telescopic cylinder 9. Example

[0025] After great saphenous vein surgery, the patient lies flat with the affected limb raised 30 degrees. After the operation, the affected limb is bandaged with an elastic bandage for pressure, and the elastic bandage is kept for at least two weeks to avoid bleeding at the surgical stripping site. Specifically in combination with this product, the patient is placed in the middle groove 2 of the position pad, and the patient's heel is placed in the circular groove heel placement area 6. According to the patient's popliteal fossa, the position of the popliteal pad 4 is moved and adjusted so that the popliteal pad 4 is below the popliteal fossa, and then the retractable support mechanism is adjusted so that the angle between the entire pad 1 and the bed is about 30 degrees.

[0026] Based on the above embodiments, the utility model can also use a restraint belt to tie the end of the positioning cushion to the bed end enclosure, so that the purpose of lifting can be achieved.

[0027] Based on the above embodiment, if both lower limbs of the patient need to be raised, this can be achieved by using two sets of positioning pads.

[0028] The above are all preferred implementations of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
