Description

Technical Field

[0001] The invention relates to the technical field of operating tables, in particular to a lithotomy position operating table with a foldable and storable footrest. Background Art

[0002] The lithotomy position originated from ancient medicine and was first used in gynecological surgery. With the development of medicine, this position has gradually been applied to other fields, such as urology and anorectal surgery, and has become the preferred position for many surgeries. In the Middle Ages, the lithotomy position was mainly used for bladder stone removal surgery, hence the name bladder lithotomy position. The lithotomy position can expose the perineum to the maximum extent, facilitate surgical operations, reduce surgical complications, and improve the success rate of surgery.

[0003] Today's operating tables are equipped with leg stands and leg pads, which can be installed at fixed positions on both sides of the bed when needed. However, the leg stands and leg pads are large in size and take up space when stored. In addition, in order to provide space for surgery, the support pad at the end of the bed must be removed, making the entire surgical preparation cumbersome and the storage and management of the bed components inconvenient. During clinical use, the leg stands and leg pads must be installed before surgery and then removed after the surgery. Often, after the surgery, the patient needs to be pushed out of the operating room on a transfer bed. The removal and transfer after the surgery will touch the patient's wound, which is unstable. The next surgery will require new leg stands and leg pads, thus extending the surgical interval and causing many problems. Summary of the invention

[0043] See also Figure 1-Figure 13As shown, the present invention provides a lithotomy position operating bed with a foldable and storable footrest, comprising a bed body 100, wherein the tail end of the bed body 100 is symmetrically and close to each other with a footrest 200 at the end of the bed body 100, and when a pair of footrests 200 at the end of the bed are close together, they are aligned with the tail end of the bed body 100 to form the length of the entire bed, so that the patient can lie flat for surgery; when performing lithotomy position surgery, it is necessary to lift both legs and spread them outwards, and the legs can be supported by rotating the pair of footrests 200 at the end of the bed horizontally outwards and raising the height;

[0044] The footrest 200 at the end of the bed comprises a bed end box 210 with an open top surface, a bed end pad 220 aligned with the top of the bed end box 210, a rotating part 230 arranged at the bottom of the bed end box 210 and driving it to rotate horizontally and extend outward, and a supporting part 240 arranged inside the bed end box 210 and used to support the bed end pad 220 to be raised and suspended; that is, the bed end pad 220 is unfolded with the outward rotation of the bed end box 210, and the bed end pad 220 is raised by the supporting part 240, and the patient's legs are supported to expose the perineum, so that lithotomy surgery can be performed;

[0045] The top surface of the foot pad 220 is symmetrically provided with grooves 221, and a stop pad 222 is clamped inside the groove 221. A blocking structure is formed by pulling out a section of the stop pad 222 to limit the legs. The inner side of the top of the foot box 210 is protruded with a convex edge 212, so that the contact area between the foot pad 220 and the foot box 210 is increased and placed stably, and when the foot pad 220 is placed on the top of the foot box 210, it plays a sealing role to prevent a large amount of dust from entering.

[0046] Specifically, the rotating part 230 includes a rotating frame 231 whose front end is fixed to the middle of the bottom surface of the tail box 210, a support cylinder 232 fixed to the bottom surface of the tail of the bed body 100 and slidably engaged with the rear cavity of the rotating frame 231, and a motor group 233 for driving the rotating frame 231 and the support cylinder 232 to first slide and then rotate; that is, the rotating frame 231 is used to support the tail box 210 to rotate, and the support cylinder 232 is used to support the rotating frame 231 to move forward and drive the tail box 210 to leave the tail end of the bed body 100 for a distance, so that the tail box 210 does not interfere when rotating;

[0047] The front and rear ends of the rotating frame 231 are rounded and a rotating hole 2312 with the same central axis as the rounded corner is opened inside. The inner diameter of the rotating hole 2312 is larger than the width of the cavity of the rotating frame 231. The left and right outer walls of the supporting cylinder 232 are symmetrically provided with vertical planes that are engaged and slid with the inner wall of the cavity of the rotating frame 231, thereby forming a limiting structure, so that the rotating frame 231 and the vertical plane of the supporting cylinder 232 are limited and slid forward;

[0048] The outer diameter of the support cylinder 232 is the same as the diameter of the rotating hole 2312, so that when the rounded end of the support frame 231 slides to the same central axis as the support cylinder 232, the rotating hole 2312 and the support cylinder 232 rotate relative to each other, causing the support frame 231 to rotate; that is, when the rotating hole 2312 and the support cylinder 232 are coaxial, the support frame 231 rotates horizontally.

[0049] Specifically, the cushion support part 240 includes a cushion support frame 241 in the form of a rectangular frame, a linkage pipe 242 rotatably connected to the middle of the cushion support frame 241, and a telescopic rod 2421 sleeved on both ends of the linkage pipe 242; the cushion support part 240 forms a parallelogram support state, thereby lifting the footrest cushion 220;

[0050] The end of the support frame 241 facing the bed body 100 is in a positional rotation connection state with the rear end bottom of the bed end pad 220, and the other end of the support frame 241 is in a shifted clamping state with the side wall of the bed end box 210;

[0051] In addition, the outer end of the telescopic rod 2421 facing the bed body 100 is in a positioning and rotating connection state with the bottom surface of the rear end box 210, and the outer end of the other telescopic rod 2421 is in a horizontal sliding connection state with the front bottom of the end pad 220; the lifting height of the end pad 220 is adjusted by adjusting the supporting angle between the support frame 241 and the bottom surface of the end box 210.

[0052] Furthermore, a knob 243 is threadedly connected to the side end wall of the linkage tube 242 facing the bed body 100; by lifting the foot pad 220, the support frame 241 and the linkage tube 242 are unfolded to be in a cross-supported state, and after adjusting the support angle of the foot pad 220, the linkage tube 242 and a telescopic rod 2421 are positioned to form a stable unfolded state by tightening the knob 243.

[0053] Furthermore, a plurality of limit grooves 211 are provided at equal intervals in the middle of the two side walls of the bed tail box 210, and the tops of each limit groove 211 on the same side are connected. The support frame 241 is composed of a pair of straight plates and round rods welded between the two ends thereof, and the two side ends of one of the round rods are coaxially connected with a limit shaft 2411, and the limit shaft 2411 is clamped with the limit groove 211; when the support angle of the support frame 241 needs to be adjusted, the limit shaft 2411 is lifted and slid in the gaps at the tops of the plurality of limit grooves 211, and then is clamped with one of the limit grooves 211. A limiting groove 211 can be used for positioning, and the limiting grooves 211 at different positions must correspond to the angle of support of the support frame 241. A rotating shaft 2412 is sleeved between the middle parts of a pair of straight plates of the support frame 241, and the middle side of the linkage tube 242 is penetrated and sleeved with the rotating shaft 2412, so that the linkage tube 242 can automatically adjust the angle when the support frame 241 is unfolded. The length of the telescopic rod 2421 is greater than half the length of the linkage tube 242, so that the telescopic rod 2421 will not slip off the linkage tube 242.

[0054] A support 224 is bolted to the middle of the rear end bottom surface of the foot pad 220. The support 224 has a U-shaped longitudinal section and is engaged with another round rod, so that when the support frame 241 is unfolded, it rotates with the foot pad 220 to automatically adjust the angle.

[0055] Furthermore, the front bottom surface of the bed end pad 220 is symmetrically provided with a bar frame 223, the outer end of one telescopic rod 2421 is engaged and slidably connected with a pair of bar frames 223, and the end side wall of the telescopic rod 2421 is embedded with a convex column, which is engaged and slidably connected with the cavity of the bar frame 223; so that the telescopic rod 2421 and the bed end pad 220 can automatically adjust the supporting position and angle;

[0056] The outer end of the other telescopic rod 2421 is rotatably connected to a hinge seat 2422 via a pin, and the hinge seat 2422 is fixedly connected to the inside of the bed end box 210 and close to the rear end bottom surface via bolts.

[0057] Specifically, a plurality of conical teeth 2311 are provided at equal intervals on the outer side of the rear end and the outer side of the rounded end of the supporting frame 231, and the motor group 233 includes a pair of transmission gears 2331, a servo motor 2332 coaxially connected to one of the transmission gears 2331, and a bracket 2333 clamped by the central axis sleeve of the pair of transmission gears 2331; the bracket 2333 is fixedly connected to the middle part of the bottom surface of the rear end of the bed 100 by bolts; a pair of transmission gears 2331 are correspondingly meshed with a plurality of conical teeth 2311 on the outer sides of the two supporting frames 231, and the pair of transmission gears 2331 are meshed for transmission; thereby, by starting the servo motor 2332 to drive one transmission gear 2331 to rotate, the other transmission gear 2331 is driven to rotate synchronously in the opposite direction, and then the two supporting frames 231 are driven to move forward and extend or move backward and reset synchronously.

[0058] Furthermore, support blocks 2321 are protruding from the bottom ends of the vertical planes on both sides of the support cylinder 232, and a pair of support blocks 2321 and the bottom surface of the support rotating frame 231 are in a sliding support state; a support column 234 is sleeved in the rotating hole 2312 at the front end of the support rotating frame 231, and the support column 234 is a stepped shaft structure and is fixedly connected to the bottom surface of the bed end box 210. The outer diameter of the bottom end of the support column 234 is larger than the outer diameter of the rounded end of the support rotating frame 231, so that the support rotating frame 231 is stably supported front and back and maintains stable movement.

[0059] In addition, in order to enhance the stability of the bed end box 210 suspended in the air, a support rod 250 for supporting the bed end box 210 to rotate is provided at the corner of the bottom end of the bed body 100, and a tray 251 that is covered and matched with the support column 234 is welded to the front end of the support rod 250; a support sleeve 260 is provided at the rear end of the support rod 250, and the support sleeve 260 is rotatably connected to the bottom of the bed body 100, so that the support rod 250 can freely extend and retract in the support sleeve 260, and rotate with the rotation of the bed end box 210, so as to always maintain a supporting state;

[0060] The top surface of the support sleeve 260 is fixedly connected to a support plate 261 with a T-shaped longitudinal section. A pair of support bars 270 are arranged under the circular plate of the support plate 261 for hanging the support plate 261 and limiting the support sleeve 260; the support bar 270 is made of PP material and its two ends are fixedly connected to the bottom surface of the bed 100 by bolts, so that the support bar 270 has flexibility to resist the squeezing force of the support sleeve 260 when it is displaced.

[0061] When the lithotomy operating bed with a foldable and retractable footrest of the present invention is used, the patient first lies flat on the bed body 100 with his buttocks close to the rear end of the bed body 100; then the patient places both legs on the two bed end pads 220 respectively, and props up the stop pad 222 for blocking and protection; then the servo motor 2332 is started to rotate forward to drive a transmission gear 2331 to rotate, driving the other transmission gear 2331 to rotate synchronously in the opposite direction, thereby driving the two support rotating frames 231 to move forward and extend outward synchronously, so as to form a space for the bed end box 210 to rotate, until the rotating hole at the rear end of the support rotating frame 231 coincides with the central axis of the supporting tube 232, and then the transmission gear 2331 and the plurality of conical teeth 2311 on the outer side of the rounded corner of the support rotating frame 231 are meshed and transmitted, so that the rotating hole 2312 and the supporting tube 232 rotate relative to each other, and the support rotating frame 231 rotates outward and unfolds;

[0062] Then, by lifting up the foot pad 220, the support frame 241 and the linkage tube 242 are unfolded to form a cross-support state. After adjusting the support angle of the foot pad 220, the linkage tube 242 and a telescopic rod 2421 are positioned to form a stable unfolded state by tightening the knob 243. When it is necessary to adjust the support angle of the support frame 241, lift the limit shaft 2411 and slide it in the gap at the top of a plurality of limit slots 211, and then engage and position it with one of the limit slots 211. The limit slots 211 at different positions must correspond to the unfolding support angle of a support frame 241, so that it is suitable for the placement and use of different patients, and then stably support the patient's legs to expose the perineum, so that lithotomy surgery can be performed.
