Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a surgical sterilization stand. Background Technology

[0002] Facial defects resulting from the resection of oral and maxillofacial tumors require the use of soft tissue from the patient's limbs (upper or lower limbs), or a combined soft tissue and bone flap, transplanted to the defect site. Vascular anastomosis is then performed to ensure a good postoperative quality of life for the patient. Thorough preoperative skin disinfection and draping of the surgical area are crucial for surgical success. Whether disinfecting or draping the upper or lower limb, it is essential to suspend the limb before disinfection to ensure a smooth disinfection process, followed by draping.

[0003] Currently, common clinical sterilization stands include a base with a lifting mechanism on the base. The lifting mechanism includes a sleeve and an inner tube slidably connected inside the sleeve. Along the length of the sleeve, the sleeve has multiple first through holes, and the inner tube has multiple second through holes. A bolt is passed through one of the first through holes and screwed into one of the second through holes to fix the inner tube in place. The top of the lifting rod is connected to a top plate, and multiple hooks are connected to the top plate. A bandage ring of appropriate length is suspended on the hooks. After the patient's ankle and foot are disinfected, they are placed inside the bandage ring, thereby achieving the effect of lifting the lower limbs off the bed surface.

[0004] However, when disinfecting the lower limbs, it is difficult to expose all the areas that need to be disinfected at the same time. In this case, one medical staff member needs to adjust the height and position of the disinfection bracket to expose other areas of the patient to be disinfected, while another medical staff member holds the patient's lower limbs to prevent the ankle and foot from falling out of the bandage and touching other places. This results in the need to re-disinfect the areas of the lower limbs that have already been disinfected, which is time-consuming, labor-intensive, and requires a lot of work. Utility Model Content

[0005] (a) The problem to be solved by this utility model is: how to fix the lower limbs that need to be supported so that the height and position of the disinfection bracket can be adjusted by only one medical staff member, which is more time-saving and labor-saving.

[0006] (II) Technical Solution This utility model provides a surgical sterilization stand, including a lifting base and a support component; The support assembly includes an adjustment mechanism, two bandages, and two support structures; The lifting base is connected to the adjustment mechanism at its top, and the lifting base is used to adjust the height of the adjustment mechanism. Two support structures are symmetrically connected to the adjustment mechanism, and the distance between the two support structures is adjusted by the adjustment mechanism.

[0008] According to one embodiment of the present invention, the adjusting mechanism includes a crossbar, a rotating component, and a locking component. The two ends of the crossbar are symmetrically rotatably connected to the rotating component, and the rotating component is fixed to the crossbar by the locking component. The support rod is an L-shaped rod, and each L-shaped rod corresponds to a rotating component. One end of the L-shaped rod is fixedly connected to the rotating component corresponding to it, and the other end is connected to the retaining component corresponding to it. The bottom of the lifting base is connected to a walking mechanism for driving the lifting base to move.

[0009] According to one embodiment of the present invention, the top of the lifting base is provided with a connecting member, and the adjusting mechanism is detachably connected to the connecting member.

[0010] According to one embodiment of the present invention, the connecting member includes a limiting block and a first locking bolt, the limiting block having a limiting groove, and one side of the limiting groove having a first screw hole. A first limiting rod is connected to the crossbar. The first limiting rod is inserted into the limiting groove. The first locking bolt passes through the first screw hole and abuts against the first limiting rod.

[0011] According to one embodiment of the present invention, the retaining member includes a second locking bolt, a pressure plate, and a connecting block; The connecting block has a second screw hole, and the second locking bolt passes through the pressure plate and is screwed into the second screw hole.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-4 As shown, one embodiment of this utility model provides a surgical sterilization stand, including a lifting base 1 and a support assembly; The support components include an adjustment mechanism 2, two bandages 6, and two support structures; The top of the lifting base 1 is connected to the adjustment mechanism 2, and the lifting base 1 is used to adjust the height of the adjustment mechanism 2. Two support structures are symmetrically connected to the adjustment mechanism 2. The distance between the two support structures is adjusted by the adjustment mechanism 2. Each bandage 6 is connected to a support structure at both ends. The two bandages 6 work together to support and fix the lower limbs.

[0022] In the initial position, the distance between the two supporting structures is at its minimum.

[0023] The two ends of the bandage 6 are connected to the corresponding support structures. The lower limbs (ankle and foot) that need support are disinfected. After disinfection, the ankle and foot are placed between the two bandages 6. The distance between the two support structures is increased by adjusting the mechanism 2, that is, the distance between the two ends of the bandage 6 is increased, and the bandage 6 is tightened. This supports and fixes the ankle and foot between the two bandages 6. Therefore, even if the medical staff does not support the patient's lower limbs, the ankle and foot are not easy to fall off between the two bandages 6. As a result, it is not easy to need to re-disinfect the disinfected area. Only one medical staff member needs to adjust the height and position of the disinfection bracket, which saves time and effort and reduces labor intensity.

[0024] According to one embodiment of this utility model, each support structure includes a support rod 3 and a retaining member 4 connected to each other. Both ends of the bandage 6 are respectively fixed to a corresponding retaining member 4. The retaining member 4 allows one end of the bandage 6 to be detachably connected to the retaining member 4, facilitating the replacement of the bandage 6. The bandage 6 is a disposable sterile bandage.

[0025] A hollow area is formed between the two support rods 3. When the ankle and foot are placed between the two bandages 6, they are located in the hollow area and are less likely to touch the structure in the disinfection bracket, reducing the probability that the disinfected area of ​​the lower limb will touch the disinfection bracket and need to be disinfected again.

[0026] According to one embodiment of the present invention, the retaining member 4 includes a second locking bolt 401, a pressure plate 402, and a connecting block 403; A second screw hole is provided on the connecting block 403. The second locking bolt 401 passes through the pressure plate 402 and is screwed into the second screw hole. The pressure plate 402 and the connecting block 403 cooperate to press the end of the bandage 6.

[0027] According to one embodiment of the present invention, a plurality of grooves 404 are provided on the side wall of the connecting block 403. The plurality of grooves 404 are arranged at intervals around the axis of the connecting block 403. Preferably, the groove 404 includes a conical groove and a straight groove that are connected. The cross-sectional area of ​​the end of the conical groove near the straight groove is smaller than the cross-sectional area of ​​the other end. The conical groove facilitates the entry of the bandage 6 into the straight groove. The straight groove is used to limit the bandage 6. Through the grooves 404, the bandage 6 can be initially limited, and one medical staff can complete the fixation of both ends of the bandage 6. The connecting block 403 has an annular groove 406 on the side near the pressure plate 402. The pressure plate 402 is connected to a pressure ring 405 that is adapted to the annular groove 406 on the side near the connecting block 403. The pressure ring 405 is pressed into the annular groove 406 to help tighten the bandage 6, which can make the fixation effect on the end of the bandage 6 better.

[0028] First, insert one end of the bandage 6 into the groove 404, passing through the gap between a set of pressure plates 402 and the connecting block 403. Then, insert the other end of the bandage 6 into the groove 404, passing through the gap between another set of pressure plates 402 and the connecting block 403. Tighten the second locking bolt 401, causing the head of the second locking bolt 401 to gradually approach the connecting block 403, pressing the bandage 6 between the connecting block 403 and the pressure plate 402. At the same time, the pressure ring 405 gradually enters the annular groove 406, assisting in pressing the bandage 6 and further preventing the bandage 6 from slipping. The pressure plate 402 can be rotatably connected to the second locking bolt 401, and the pressure plate 402 can also be fixedly connected to the second locking bolt 401.

[0029] When removing bandage 6, rotate the second locking bolt 401 in the opposite direction for easy disassembly and assembly.

[0030] Compared to the traditional method of hanging bandage rings with hooks, the method of fixing bandage 6 with fixing component 4 is more stable and less likely to cause bandage 6 to fall off due to accidental contact with the disinfection bracket.

[0031] According to one embodiment of the present invention, the adjusting mechanism 2 includes a crossbar 202, a rotating component 203 and a locking component. The two ends of the crossbar 202 are symmetrically rotatably connected to the rotating component 203, and the rotating component 203 is fixed to the crossbar 202 by the locking component. The support rod 3 is an L-shaped rod, and the L-shaped rod corresponds one-to-one with the rotating part 203. One end of the L-shaped rod is fixedly connected to the corresponding rotating part 203, and the other end of the L-shaped rod is connected to the corresponding retaining part 4.

[0032] One end of the L-shaped rod is connected to the rotating component 203, and the other end is connected to the retaining component 4. By rotating the rotating component 203, the L-shaped rod rotates accordingly, thereby changing the distance between the ends of the two L-shaped rods near the retaining component 4. When adjusted to a suitable position, the rotating component 203 is secured by the locking component. Loosening the two bandages 6 facilitates placement of the ankle and foot, while tightening the two bandages 6 facilitates fixation of the ankle and foot.

[0033] Since the tightness of the bandage 6 is adjusted by rotating the L-shaped rod horizontally to adjust the distance between the two ends of the bandage 6, the force applied by rotating the L-shaped rod is less than the weight of the patient's lower limbs, thus reducing labor intensity and saving effort.

[0034] Specifically, both ends of the crossbar 202 are provided with shaft holes, the rotating part 203 is rotatably connected to the corresponding shaft hole, and the locking part includes a third locking bolt 204. A third screw hole is connected to one side of the shaft hole. The third locking bolt 204 passes through the third screw hole and abuts against the rotating part 203, so that the rotating part 203 can be fixed relative to the crossbar 202.

[0035] Preferred, such as Figure 1 As shown, the rotating component 203 includes a rotating shaft and a first fixing bolt and a second fixing bolt screwed to both ends of the rotating shaft. The first fixing bolt is first screwed to the end of the rotating shaft that connects to the L-shaped rod. The rotating shaft passes through the shaft hole, and the second fixing bolt is screwed onto the rotating shaft. The distance between the first fixing bolt and the second fixing bolt is slightly greater than the length of the rotating shaft, which ensures that the rotating shaft can rotate normally within the shaft hole and also restricts the movement of the rotating shaft along its axis. Of course, the distance between the second fixing bolt and the first fixing bolt can also be adjusted by screwing the second fixing bolt to allow the rotating shaft to rotate or be fixed relative to the shaft hole. This does not depart from the design concept of this utility model, and therefore should fall within the protection scope of this utility model.

[0036] The bottom of the lifting base 1 is connected to a walking mechanism for driving the lifting base 1 to move. It should be noted that since the horizontal rotation adjustment of the bandage 6 spacing will simultaneously change the distance between the bandage 6 and the upper body of the human body, during the adjustment process, the walking mechanism drives the entire disinfection bracket to move, so that the distance between the bandage 6 and the upper body of the human body is adjusted at the same time.

[0037] Of course, in this embodiment, the adjustment mechanism 2 can also take other forms. For example, the adjustment mechanism 2 includes a strip frame with a bidirectional lead screw inside. One end of the bidirectional lead screw is connected to a knob, and two support rods 3 are slidably connected to the strip frame. The two support rods 3 are respectively screwed to both ends of the bidirectional lead screw. By rotating the knob, the two support rods 3 move closer or further apart under the combined action of the bidirectional lead screw and the strip frame, thereby making the distance between the two ends of the bandage 6 smaller or larger, and changing the tightness of the bandage 6. Its purpose does not depart from the design concept of this utility model; therefore, it should fall within the protection scope of this utility model.

[0038] According to one embodiment of the present invention, the top of the lifting base 1 is provided with a connector 5, and the adjusting mechanism 2 is detachably connected to the connector 5.

[0039] According to one embodiment of the present utility model, the connector 5 includes a limiting block 501 and a first locking bolt 502. A limiting groove 503 is provided on the limiting block 501, and a first screw hole is connected to one side of the limiting groove 503. A first limiting rod 201 is connected to the crossbar 202. The first limiting rod 201 is inserted into the limiting groove 503. The first locking bolt 502 passes through the first screw hole and abuts against the first limiting rod 201. Insert the first limiting rod 201 into the limiting groove 503, and tighten the first locking bolt 502 so that its tail (end) enters the limiting groove 503 and tightly abuts against the first limiting rod 201, thus fixing the first limiting rod 201 in the limiting groove 503.

[0040] According to one embodiment of the present invention, the disinfection bracket further includes a support plate 7 for supporting the upper limbs, and a second limiting rod 8 is connected to the support plate 7. The second limiting rod 8 has the same structure as the first limiting rod 201.

[0041] Because the connecting piece 5 allows for quick assembly and disassembly of the support assembly, when the lifting base 1 is used for upper limb disinfection, the first locking bolt 502 can be screwed out of the limiting groove 503, the first limiting rod 201 can be removed, and the support assembly can be separated from the lifting base 1. The second limiting rod 8 can be inserted into the first limiting rod 201, and the first locking bolt 502 can be screwed out so that its tail enters the limiting groove 503 and abuts against the second limiting rod 8. Then, the support plate 7 can be installed on the lifting base 1, and the lifting base 1 can be adjusted to be flush with the operating table. After the upper limb is disinfected, the upper limb can be placed on the support plate 7, which is covered with two or more layers of disinfectant towels.

[0042] Furthermore, due to the limited space in the operating room, the support plate 7 is designed as a long strip with curved and triangular sections at both ends; the curved section is used to place the upper limbs, and the sides of the triangular section can fit snugly against the edge of the bed, further saving space.

[0043] According to one embodiment of the present invention, two bandages 6 are arranged sequentially along the height direction of the lifting base 1. The disinfected ankle is passed between the two bandages 6. When the upper bandage 6 is tightened, it works in conjunction with the lower bandage 6 to prevent the ankle joint and foot from slipping. When the two bandages 6 are tightened, the fixation effect on the ankle is optimal.

[0044] According to one embodiment of the present invention, the lifting base 1 is a foot-operated hydraulic lifting rod. With the foot-operated hydraulic lifting rod, medical personnel can change the height of the lifting base 1 by stepping on the foot-operated hydraulic lifting rod, thereby changing the height of the bandage 6. The adjustment method is time-saving and labor-saving. The foot-operated hydraulic lifting rod is preferably a hydraulic lifting rod with anti-fall self-locking function to further improve the stability of the disinfection bracket when it is raised and lowered. The walking mechanism includes a mobile chassis 9, the pushing end of a foot-operated hydraulic lifting rod is connected to a limit block 501, and its fixed end is connected to the mobile chassis 9.

[0045] The mobile chassis 9 consists of a base plate and multiple casters with foot brakes, allowing the disinfection stand to be quickly moved to a designated position and fixed as needed, saving time and effort. When disinfecting the patient's lower limb groin, the patient bends their knee while the mobile disinfection stand is moved closer to their upper body, exposing the groin for disinfection. The mobile chassis 9 also has counterweights. These counterweights lower the center of gravity of the entire disinfection stand, improving its stability, preventing tipping, and enhancing safety.

[0046] Specifically, during lower limb disinfection, the support component is quickly assembled onto the lifting base 1 via the connector 5. A sterile plastic protective sleeve is then placed over the two support structures within the support component, and the ends of the bandage 6 are secured by the fixing component 4 (the sterile plastic protective sleeve is made of a flexible film material, so it does not affect the insertion of the bandage 6 into the groove 404, nor does it affect the placement of the bandage 6 in the gap between the pressure plate 402 and the connecting block 403). After securing, medical personnel adjust the height of the bandage 6 according to the patient's height and leg length by adjusting the foot-operated hydraulic lifting rod. After disinfecting the patient's foot and ankle, the foot and ankle are placed between the two bandages 6. By rotating the rotating component 203, the distance between the two ends of the bandage 6 is increased, and then the rotating component 203 is fixed, thereby tightening the bandage 6 to secure the ankle and foot. After completion, the exposed lower limb area is disinfected. The position and height of the disinfection bracket are then adjusted to expose other areas of the lower limb to be disinfected, and these areas are then disinfected.
