[0002] In spinal surgery and postoperative care, precise control of drainage pressure is crucial for the patient's recovery.
[0003] Traditional drainage devices often suffer from problems such as inconvenient height adjustment and unstable drainage pressure, which may lead to poor or excessive drainage, resulting in serious complications such as pneumothorax and hemothorax, increasing patient suffering and medical risks. At the same time, different patients have different requirements for the optimal working position of the drainage device due to differences in height, weight and bed height, and existing devices are difficult to flexibly adapt to these diverse needs, which brings great challenges to medical and nursing work. Therefore, a spinal surgery drainage nursing device is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a spinal surgery drainage and nursing device. By incorporating a lifting assembly, specifically by rotating the handle at the end of the worm gear, the worm wheel and threaded rod rotate. The lifting rod, due to its engagement with the threaded rod, moves axially along the support sleeve, achieving lifting and lowering. A limiting groove and a limiting strip cooperate to prevent the lifting rod from rotating. The worm gear and worm wheel are self-locking, maintaining a stable height of the lifting rod. This allows for adjustment of the drainage device height, solving problems such as inconvenient height adjustment and unstable drainage pressure often found in traditional drainage devices. These issues can lead to poor or excessive drainage, potentially causing serious complications such as pneumothorax and hemothorax, increasing patient suffering and medical risks. Furthermore, different patients have varying requirements for the optimal working position of the drainage device due to differences in height, weight, and bed height, and existing devices struggle to flexibly adapt to these diverse needs, posing a significant challenge to medical and nursing care.

[0006] Furthermore, the worm gear passes through the support sleeve and extends to the front side. The outer surface of the worm gear is rotatably connected to the inner edge of the support sleeve. The top of the lifting rod is connected to the bottom of the drainage device through a mounting bracket. The worm gear and worm wheel reduce the downward fall of the lifting rod through self-locking.
[0007] Furthermore, the cable harness assembly includes a support frame fixedly connected to the outer surface of the lifting rod. The support frame is located below the drainage device. Locking grooves are provided on the left and right sides of the top of the support frame. Several movable frames are slidably connected to the outer surface of the support frame, and the components connected to the several movable frames are the same.
[0008] Furthermore, the movable frame has a cavity inside, and a rotating rod is rotatably connected to the center of the movable frame. The rotating rod passes through the movable frame and extends to the top and inner side. A worm gear is provided inside the cavity. The inner end of the worm gear is fixedly connected to the outer surface of the rotating rod, and a fixing rod is fixedly connected to the outer end of the worm gear. The bottom of the fixing rod is fixedly connected to the bottom of the inner wall of the cavity, and a knob is welded to the top of the rotating rod.
[0009] Furthermore, a limiting plate is provided above the worm gear, and the right side of the inside of the limiting plate is fixedly connected to the outer surface of the rotating rod. Limiting blocks are fixedly connected to the left side and the back side of the top of the cavity inner wall. The outside of the limiting plate is in contact with the outside of the two limiting blocks respectively. The two limiting blocks are used to limit the movement trajectory of the limiting plate.
[0010] Furthermore, a locking block is provided on the inner side of the movable frame. The center of the locking block is fixedly connected to the bottom of the outer surface of the rotating rod. The outer surface of the locking block is in contact with the inner wall of the locking groove. Elastic wire clamps are installed on both the front and back of the movable frame. Both the outer surface of the locking block and the inner wall of the locking groove are anti-slip.
[0011] Furthermore, the limiting component includes two limiting slide bars, the side of the two limiting slide bars that is far apart from each other is fixedly connected to the inner wall of the support sleeve, and two limiting slide grooves are opened on the outer surface of the lifting rod, the interior of the two limiting slide grooves is slidably connected to the outer surface of the limiting slide bars respectively, the limiting slide grooves and the limiting slide bars are used to limit and guide the movement trajectory of the lifting rod.
[0012] This utility model has the following beneficial effects: 1. This utility model, by setting up a lifting component, specifically by rotating the crank at the end of the worm gear, drives the worm wheel and threaded rod to rotate. The lifting rod moves axially along the support sleeve due to its engagement with the threaded rod, thereby achieving lifting.

[0013] 2. This utility model incorporates a cable management assembly, specifically an elastic cable clamp mounted on a movable frame. Made of elastic material, the clamp secures and initially fixes the drainage tube, preventing excessive compression. By rotating the rotating rod 90 degrees, the locking block disengages from the locking groove, allowing for horizontal adjustment of the movable frame. A limiting plate cooperates with the limiting block to restrict the rotation angle of the rotating rod. The worm gear contracts and stores force when the rotating rod rotates, and rebounds after release, resetting the rotating rod and locking block, increasing the resistance to movement of the movable frame and fixing it in place. This design prevents the tube from being pulled, twisted, or dislodged during patient movement, ensuring unobstructed drainage, reducing the risk of skin damage and infection, and facilitating examination and operation by medical staff.

[0019] Please see Figures 1-7As shown, this utility model is a spinal surgical drainage and nursing device, including a support component base 111, a drainage device 112 disposed above the base 111, and several self-locking casters 113 installed at the bottom edge of the base 111. It also includes an auxiliary mechanism 2, which is mounted above the base 111. The auxiliary mechanism 2 includes a lifting assembly 21 mounted on the base 111 and a wire harness assembly 22 mounted on the lifting assembly 21. The lifting assembly 21 includes a support sleeve 211 fixed to the top of the base 111, a lifting rod 212 slidably connected inside the cavity of the support sleeve 211, and a threaded rod 213 threadedly connected to the center of the lifting rod 212.

A worm 214 is meshed with the outer surface of the worm gear 215. A limit component is installed inside the support sleeve 211. A crank is welded to the front of the worm 214. Rotating the crank at the end of the worm 214 drives the worm gear 215 and the threaded rod 213 to rotate. The lifting rod 212 moves axially along the support sleeve 211 due to its meshing with the threaded rod 213, realizing lifting and lowering. The limiting slide groove 216 and the limiting slide strip 217 cooperate to prevent the lifting rod 212 from rotating. The worm 214 and the worm gear 215 are self-locking to keep the height of the lifting rod 212 stable. The height of the drainage device 112 can be adjusted to precisely control the drainage pressure, adapt to the needs of patients, improve the flexibility of nursing care, and reduce the intensity of medical and nursing operations.
[0020] The worm 214 passes through the support sleeve 211 and extends to the front. The outer surface of the worm 214 is rotatably connected to the inner edge of the support sleeve 211. The top of the lifting rod 212 is connected to the bottom of the drainage device 112 through the mounting bracket. The worm 214 and the worm wheel 215 reduce the fall of the lifting rod 212 through self-locking.
[0021] The cable harness assembly 22 includes a support frame 221 fixedly connected to the outer surface of the lifting rod 212. The support frame 221 is located below the drainage device 112. Locking grooves 222 are provided on the left and right sides of the top of the support frame 221. Several movable frames 223 are slidably connected to the outer surface of the support frame 221. The components connected to the movable frames 223 are identical. A cavity 224 is provided inside the movable frame 223. A rotating rod 227 is rotatably connected to the center of the movable frame 223. The rotating rod 227 passes through the movable frame 223 and extends to the top and inner side. The cavity 224 contains... A worm gear 225 is provided, with its inner end fixedly connected to the outer surface of a rotating rod 227. A fixing rod 226 is fixedly connected to the outer end of the worm gear 225, with its bottom fixedly connected to the bottom of the inner wall of the cavity 224. A knob is welded to the top of the rotating rod 227. A limit piece 228 is provided above the worm gear 225, with its inner right side fixedly connected to the outer surface of the rotating rod 227. Limit blocks 229 are fixedly connected to the left side and back of the top of the inner wall of the cavity 224. The outer side of the limit piece 228 contacts the outer side of the two limit blocks 229, which are used for limiting... The movement trajectory of the position plate 228 is limited. A locking block 2210 is provided inside the moving frame 223. The center of the locking block 2210 is fixedly connected to the bottom of the outer surface of the rotating rod 227. The outer surface of the locking block 2210 contacts the inner wall of the locking groove 222. Elastic wire clamps 2211 are installed on both the front and back of the moving frame 223. The outer surface of the locking block 2210 and the inner wall of the locking groove 222 are both anti-slip. The elastic wire clamps 2211 are installed on the moving frame 223 and are made of elastic material. They can clamp and initially fix the drainage tube to avoid excessive compression. Rotating the rotating rod 227 by 90 degrees causes the locking block 2210 to disengage from the locking groove 222, enabling the horizontal movement adjustment of the moving frame 223. The limiting piece 228 cooperates with the limiting block 229 to limit the rotation angle of the rotating rod 227. The worm gear 225 contracts and stores force when the rotating rod 227 rotates, and rebounds after being released, causing the rotating rod 227 and the locking block 2210 to reset, increasing the movement resistance of the moving frame 223 and fixing the moving frame 223. This design prevents the tubing from being pulled, twisted or dislodged when the patient moves, ensuring smooth drainage, reducing the risk of skin damage and infection, and facilitating examination and operation by medical staff.
[0022] The limiting component includes two limiting slide bars 217. The sides of the two limiting slide bars 217 that are far apart from each other are fixedly connected to the inner wall of the support sleeve 211. Two limiting slide grooves 216 are opened on the outer surface of the lifting rod 212. The interior of the two limiting slide grooves 216 is slidably connected to the outer surface of the limiting slide bars 217 respectively. The limiting slide grooves 216 and the limiting slide bars 217 are used to limit and guide the movement trajectory of the lifting rod 212.
[0023] One specific application of this embodiment is as follows: When in use, the device is based on "negative pressure guidance + closed collection". The drainage device 112 completes the drainage and collection of liquid. One end of the drainage tube is connected to the patient's postoperative spinal wound or body cavity, and the other end is connected to the internal passage of the drainage device 112. The natural negative pressure is formed by the height difference between the drainage device 112 and the wound, or the negative pressure is generated by the built-in negative pressure component of the device. The blood, exudate and other liquids in the body are guided into the drainage device 112 along the drainage tube to achieve effective drainage and collection of liquid. At the same time, the closed structure can prevent the drainage fluid from flowing back and reduce the risk of infection. The base 111 provides stable support for the entire device. The self-locking casters 113 can realize the overall movement of the device. After moving to the target position, the casters are locked to ensure that the position of the device is fixed during use. During use, the height of the drainage device 112 can be adjusted by rotating the handle at the end of the worm 214. During the rotation of the worm 214, the worm wheel 215 rotates synchronously, which in turn rotates the threaded rod 213. At this time, because the lifting rod 212 engages with the threaded rod 213 on its outer surface, when the threaded rod 213 rotates, the lifting rod 212 moves axially along the support sleeve 211 under the threaded engagement, thus achieving the lifting action. Simultaneously, the limiting groove 216 on the inner wall of the support sleeve 211 slides with the limiting strip 217 on the outer wall of the lifting rod 212, preventing the lifting rod 212 from rotating synchronously with the threaded rod 213 and ensuring stable lifting direction. Once the lifting rod 212 has driven the drainage device 112 to the target height, the worm 214 is stopped. Because the meshing between the worm 214 and the worm wheel 215 has a self-locking characteristic, the worm gear mechanism has low reverse transmission efficiency and requires no external force to drive it. The device does not rotate on its own, keeping the threaded rod 213 in a fixed position and locking the height of the lifting rod 212. This ensures that the drainage device 112 is stably at the set height, guaranteeing constant drainage pressure. During the lifting and lowering process of the lifting rod 212, the drainage device 112 is moved synchronously, completing the height adjustment of the drainage device 112, precisely controlling the drainage pressure, and reducing the occurrence of drainage abnormalities. The drainage bottle can be adjusted to a suitable height below the wound according to the patient's postoperative bed posture or wound position. This can prevent poor drainage and fluid accumulation due to insufficient height, and also reduce the occurrence of excessive drainage due to excessive height difference, reducing the risk of pneumothorax, hemothorax, etc. At the same time, it is adaptable to different patients and scenarios, improving the flexibility of nursing care. When facing patients of different heights and weights, or different bed heights, there is no need to change the device or move the bed. The device can be placed in the optimal working position simply by raising and lowering it. It is especially suitable for spinal patients who need to frequently adjust their position after surgery, and reduces the intensity of medical and nursing operations and nursing time. During use, the pipeline can be constrained. Specifically, the elastic cable clamp 2211, made of elastic material, is installed on the movable frame 223 and has a certain degree of opening and closing. The drainage pipeline is placed inside the elastic cable clamp 2211, which clamps the pipeline using its own elastic tension, achieving initial fixation. Simultaneously, the elastic structure prevents excessive compression of the pipeline, thus avoiding drainage obstruction. Subsequently, the spacing between the various pipelines can be adjusted according to usage requirements. Specifically, the rotating rod 227 is rotated 90 degrees. During the rotation of the rotating rod 227, the locking block 2210 is moved accordingly. As the movement progresses, the outer ring of the locking block 2210 disengages from the locking groove 222, allowing for horizontal adjustment of the overall position of the moving frame 223. Simultaneously, the rotation of the rotating rod 227 drives the limiting piece 228 to move. During this movement, the limiting piece 228 contacts the limiting block 229 on the back, which then limits the rotation angle of the limiting piece 228. Simultaneously, the rotation of the rotating rod 227 drives the worm gear 225 to move, causing the end of the worm gear 225 to retract due to the limiting action of the fixing rod 226. After the moving frame 223 is adjusted to the appropriate position, the rotating rod 227 is released. At this time, the worm gear 225 will generate a certain rebound force and drive the rotating rod 227 to reset. During the reset process of the rotating rod 227, the locking block 2210 will also reset synchronously. At this time, the outer ring of the locking block 2210 will contact the inner wall of the locking groove 222 again, increasing the resistance when the moving frame 223 moves, thereby achieving the limitation and fixation of the moving frame 223. At the same time, while the rotating rod 227 is resetting, the limiting piece 228 will also reset synchronously and contact the limiting block 229 on the left side. Therefore, the left side... The limiting block 229 is used to limit the reset angle of the locking block 2210. By constraining the tubing and adjusting the spacing, it can effectively prevent the tubing from being pulled, twisted or dislodged when the patient turns over or moves, ensuring continuous unobstructed drainage and reducing drainage failure caused by tubing problems. At the same time, it reduces friction between the tubing and the skin, reducing the probability of local skin damage and infection, meeting the requirements of aseptic care. In addition, the orderly constrained tubing allows medical staff to quickly see the tubing connection status, making it easy to check for blockages or leaks. It also facilitates quick positioning when changing drainage bottles or adjusting tubing, reducing operational errors.
