Description

Technical Field

[0001] This utility model relates to the field of electric operating table technology, specifically an electric operating table that facilitates the lifting of the patient's legs. Background Technology

[0002] In gynecological, urological, and laparoscopic surgeries, patients often require the lithotomy or modified lithotomy position to ensure adequate exposure of the surgical field. Traditional operating tables typically have fixed leg supports, making it difficult to flexibly adjust the leg flexion and extension angles and abduction degrees according to intraoperative needs. This can lead to insufficient exposure of the surgical field or an increased risk of nerve and blood vessel compression. Furthermore, the adjustment process with existing devices is cumbersome, requiring multiple people to assist, thus impacting surgical efficiency.

[0003] Currently, patent publication number CN215536187U discloses a limb fixation device for gynecological operating room care, including a base and a limiting plate. A first electric telescopic rod is fixedly connected to the upper surface of the base. A bed board is rotatably connected to the telescopic end of the first electric telescopic rod. A second electric telescopic rod is fixedly connected to the upper surface of the bed board. A headrest is fixedly connected to the telescopic end of the second electric telescopic rod. A telescopic column is fixedly connected to the lower surface of the headrest. A support plate is fixedly connected to the surface of the bed board. A guard plate and a limiting block are fixedly connected to the upper surface of the support plate. A locking bolt is threaded onto the surface of the limiting block. A rubber pad is fixedly connected to the lower end of the locking bolt. A lead screw is fixedly connected to the inner wall of the bed board. A sliding block is slidably connected to the surface of the lead screw. A cylinder is fixedly connected to the surface of the sliding block. A limiting column is fixedly connected to the upper end of the sliding block. A leg fixator is slidably connected to the inner wall of the limiting column. A circular hole is opened on the surface of the limiting column. An insert block is slidably connected to the inner wall of the circular hole. A groove adapted to the insert block is opened on the surface of the leg fixator.

[0004] The existing technical solution involves setting up a leg immobilizer, Velcro, a lead screw, a sliding block, and a limiting post. In use, the cylinder is slid after rotating the nut, which causes the sliding block to move on the lead screw. When adjusted to the appropriate position, the nut is tightened to fix the sliding block. The patient places their leg on the leg immobilizer and the Velcro is glued together. The height of the leg immobilizer can be adjusted by moving the inserts into different holes.

[0005] However, the existing technical solutions still have the following drawbacks in operation:

[0006] (1) In the existing technical solution, since each patient has a different height, the height that the legs need to be raised is also different. Every time the operator adjusts the height of the leg fixation device according to the patient's comfort, the operator needs to take out the insert block and adjust the height of the leg fixation device. Then the insert block is inserted again into the surface of the limiting column with a round hole. In addition, the height of the two leg fixation devices needs to be adjusted in turn. For the same patient, the height of the leg fixation device needs to be adjusted multiple times. The operation process is cumbersome, wastes time, and results in low work efficiency.

[0007] (2) The limiting column and leg fixation device in the existing technical solution are located on the operating table and cannot be stored. When it is not necessary to raise the patient's legs, the limiting column and leg fixation device occupy the space of the operating table, affecting the spatial layout of the operating room. This is especially inconvenient in small operating rooms or when the bed needs to be moved frequently. When transferring patients after surgery, the protruding limiting column and leg fixation device may collide with medical staff or equipment, increasing the risk of accidental injury. Utility Model Content

[0008] This utility model aims to provide an electric operating table that facilitates the lifting of patients' legs. It mainly addresses the technical problems of existing technology, such as the need for frequent adjustment of the leg fixation device height due to differences in patient height. Each adjustment requires removing the insert block, adjusting, and then re-inserting it into the round hole of the limiting column. This process may be repeated multiple times even for the same patient, which is cumbersome and inefficient. Furthermore, the limiting column and leg fixation device occupy operating table space, affecting the layout of small operating rooms and bed movement. During postoperative transfer, the protruding structure is prone to colliding with medical equipment, posing a safety hazard.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0010] An electric operating table that facilitates leg lifting for patients includes an electric operating table body with an internal mounting cavity. Both sides of the electric operating table body have first sliding grooves communicating with the mounting cavity. The inner wall of each of the first sliding grooves has a second sliding groove. A slider is slidably connected within the second sliding groove. A connecting rod is rotatably connected to one side of each slider. Both ends of the connecting rod pass through the sliders and are fixedly connected to a U-shaped support rod. The outer wall of the U-shaped support rod is symmetrically and rotatably connected to a leg support block. A concave groove is formed on the upper surface of each leg support block. A limiting component for fixing the tilt angle of the U-shaped support rod is provided on the outer wall of the connecting rod. A driving component for moving the sliders is provided within the mounting cavity.

[0011] The working principle and beneficial effects of this utility model:

[0012] 1. Working Principle: When it is necessary to lift the patient's legs, the drive component drives the slider to move along the second slide groove. After moving to a suitable horizontal position, the limiting component releases its restriction on the connecting rod. Then, the U-shaped support rod is rotated so that it is above the bed surface. The rotation of the U-shaped support rod will cause the leg support block connected to the outer wall to rotate synchronously, placing the patient's legs in the concave groove on the upper end of the leg support block. Then, the rotation angle of the U-shaped block is finely adjusted according to the patient's comfort to achieve the effect of lifting the patient's legs. The limiting component restricts the connecting rod again. At this time, the rotating rod drives the U-shaped support rod to rotate towards the patient, and the patient's legs are lifted.

[0013] 2. Beneficial effects:

[0014] (1) Existing technology uses a combination of a limiting column, a leg fixator, and a plug. By moving the plug into different round holes on the surface of the limiting column, the height of the leg fixator can be adjusted according to different patients. This solves the technical problem that existing devices are inconvenient to adjust the distance between the fixation device and the limb because patients have different heights. However, due to the difference in patient height, the height of the leg fixator needs to be adjusted frequently. Each adjustment requires removing the plug, adjusting, and then re-inserting it into the round hole of the limiting column. Even for the same patient, this operation may be repeated many times, which is cumbersome and inefficient. This solution uses a combination of a connecting rod, a slider, a U-shaped support rod, a leg support block, and a limiting component. By rotating the U-shaped support rod to adjust the angle of the U-shaped support block, the leg height of different patients can be raised. At the same time, both legs can be raised. The operation is simple and can be completed in a short time. This solves the technical problem that patients have different heights and need to adjust the height of the leg fixator frequently. Each adjustment requires removing the plug, adjusting, and then re-inserting it into the round hole of the limiting column. Even for the same patient, this operation may be repeated many times, which is cumbersome and inefficient.

[0015] (2) This solution, through the combined use of toothed plate, rotating rod, gear and fixed block connected to the external thread of the rotating rod, can adjust the horizontal position of the U-shaped support rod according to the patient's needs and can be fixed in any position, thereby improving the patient's comfort.

[0016] Preferably, the limiting component includes a ratchet fixed to the outer wall of the connecting rod, and a pawl rotatably connected to the outer wall of the slider via a spring shaft. One end of the pawl abuts against the groove of the ratchet. The pawl is disengaged from its groove, and then the U-shaped support block is rotated according to the patient's needs. The U-shaped support block drives the leg support block to rotate synchronously. The patient places their leg in the concave groove on the upper surface of the leg support block. The tilt angle of the U-shaped support block is then finely adjusted according to the patient's needs to elevate the patient's leg. When the U-shaped support rod is adjusted to a suitable angle, the pawl is released. Because the slider is rotatably connected to the pawl via a spring shaft, one end of the pawl abuts against the groove of the ratchet again under the spring's restoring force. At this point, the U-shaped support rod will no longer rotate towards the patient.

[0017] Preferably, the driving assembly includes a toothed plate fixed to the lower side wall of the mounting cavity, a rotating rod slidably connected inside the mounting cavity, both ends of the rotating rod extending sequentially into a first sliding groove and a second sliding groove and rotatably connected to one side of the slider, one end of the rotating rod passing through the slider and extending out of the first sliding groove, and a gear fixed to the outer wall of the rotating rod meshing with the toothed plate; rotating the rotating rod drives the gear fixed to the outer wall to rotate, and since the gear meshes with the toothed plate, the gear moves along the toothed plate when it rotates, at which time the rotating rod and the gear move horizontally synchronously, thereby driving the slider to move horizontally along the second sliding groove, thereby achieving the adjustment of the horizontal position of the U-shaped support block.

[0018] Preferably, the outer wall of the end of the rotating rod extending from the first sliding groove is provided with an external thread, and a fixing block is provided on the outer wall of the rotating rod. The inner wall of the fixing block is provided with an internal thread that matches the external thread. The fixing block is threaded onto the external thread section of the rotating rod. Several circumferentially evenly arranged anti-slip blocks are fixed to the outer wall of the fixing block. When the U-shaped support rod is moved to the desired position, the fixing block is turned, and the fixing block moves along the external thread until one end of the fixing block abuts against one side of the electric operating table. At this time, the slider is fixed and cannot move, and thus the horizontal position of the U-shaped support rod is fixed. By using the external thread on the outer wall of the rotating rod and the internal thread on the inner wall of the fixing block in cooperation, when it is necessary to move the U-shaped support rod, the fixing block is loosened, and the position of the slider can be moved by rotating the rotating rod at the same time, thereby adjusting the horizontal position of the U-shaped support rod.

[0019] Preferably, a turntable is fixedly connected to one end of the rotating rod extending out of the first sliding groove; it is very difficult to rotate the rotating rod directly by hand and it will hurt the hand. By rotating the turntable to drive the rotating rod to rotate, it is more labor-saving and avoids direct contact between the hand and the rotating rod.

[0020] Preferably, an L-shaped rod is fixed to the outer wall of the end of the pawl furthest from the ratchet; when it is necessary to rotate the U-shaped support rod toward the patient, one end of the pawl needs to be disengaged from the tooth groove of the ratchet, and the pawl can be moved by moving the L-shaped rod, which is more convenient and avoids inserting fingers into the first groove.

[0021] Preferably, a protective pad is fixedly connected to the concave groove on the leg support block; when the patient's leg rests on the concave groove on the leg support block, the protective pad fixedly connected to the concave groove can reduce the pressure on the leg and make the patient's leg more comfortable.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-5An electric operating table for facilitating leg lifting is shown, comprising an electric operating table body 1, an internal mounting cavity 2, and first sliding grooves 3 on both sides of the electric operating table body 1 communicating with the mounting cavity 2. A second sliding groove 4 is formed on the inner wall of the first sliding groove 3, and a slider 5 is slidably connected within the second sliding groove 4. A connecting rod 6 is rotatably connected to one side of the two sliders 5, and both ends of the connecting rod 6 pass through the sliders 5 and are fixedly connected to a U-shaped support rod 7. A leg support block 8 is symmetrically and rotatably connected to the outer wall of the U-shaped support rod 7. A concave groove is formed on the upper surface of the leg support block 8. The inner protective pad 18 is fixedly connected. The outer wall of the connecting rod 6 is provided with a limiting component for fixing the tilt angle of the U-shaped support rod 7. The limiting component includes a ratchet 9 fixedly connected to the outer wall of the connecting rod 6. The outer wall of the slider 5 is rotatably connected to a pawl 10 through a spring shaft. Through the cooperation of the ratchet 9 and the pawl 10, when the U-shaped support rod 7 rotates to a suitable angle, it can limit the U-shaped support rod 7 from continuing to rotate towards the patient, thus limiting the U-shaped support rod 7 to the required angle. One end of the pawl 10 abuts against the tooth groove of the ratchet 9. The outer wall of the end of the pawl 10 away from the ratchet 9 is fixedly connected with an L-shaped rod 17. The mounting cavity 2 is provided with a driving component for driving the slider 5 to move.

[0030] The drive assembly includes a toothed plate 11 fixed to the lower side wall of the mounting cavity 2. A rotating rod 12 is slidably connected inside the mounting cavity 2. Both ends of the rotating rod 12 extend sequentially into the first slide groove 3 and the second slide groove 4 and are rotatably connected to one side of the slider 5. One end of the rotating rod 12 passes through the slider 5 and extends out of the first slide groove 3. A gear 13 is fixed to the outer wall of the rotating rod 12 and meshes with the toothed plate 11. Through the cooperation of the toothed plate 11, the gear 13, and the rotating rod 12, rotating the rotating rod 12 drives the gear 13 to rotate and move horizontally along the toothed plate 11. In turn, the rotating rod 12 drives the slider 5 to move horizontally along the second slide groove 4, thereby adjusting the horizontal position of the U-shaped support rod 7. The outer wall of the end of the rotating rod 12 extending out of the first slide groove 3 is provided with an external thread 14. A fixing block 15 is provided on the outer wall of the rotating rod 12. The inner wall of the fixing block 15 is provided with an internal thread that matches the external thread 14. The fixing block 15 is threaded onto the external thread section of the rotating rod 12. Several anti-slip blocks 16 are fixedly connected to the outer wall of the fixing block 15. When it is necessary to move the U-shaped support rod 7, the fixing block 15 can be loosened so that the rotating rod 12 can drive the gear 13 to move along the tooth plate 11 and move the position of the slider 5 at the same time, thereby adjusting the horizontal position of the U-shaped support rod 7. A turntable 19 is fixedly connected to the end of the rotating rod 12 extending out of the first slide groove 3.

[0031] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0032] When it is necessary to lift the patient's leg, since the fixing block 15 is threaded onto the rotating rod 12, first loosen the fixing block 15. The fixing block 15 moves along the external thread section on the outer wall of the rotating rod 12. Then rotate the turntable 19. The rotation of the turntable 19 drives the rotating rod 12, which is fixed on one side, to rotate. The rotation of the rotating rod 12 drives the gear 13, which is fixed on the outer wall, to rotate. Since the gear 13 is meshed with the toothed plate 11, which is fixed on the inner wall of the mounting cavity 2, the gear 13 moves horizontally along the toothed plate 11 while rotating. The movement of the gear 13 will also drive the rotating rod 12 to rotate. The rotating rod 12 moves horizontally, causing the slider 5 to move along the second slide groove 4. The slider 5 moves, driving the connecting rod 6 to move. The connecting rod 6 moves, causing the U-shaped support rod 7, which is fixed at both ends, to move. This adjusts the horizontal position of the U-shaped support rod 7. After the U-shaped support rod 7 moves to the appropriate position, the fixing block 15 is tightened. After one end of the fixing block 15 abuts against one side of the electric operating table body 1, the rotating rod 12 cannot move horizontally, and consequently, the slider 5 cannot move horizontally either. Consequently, the connecting rod 6 and the U-shaped support rod 7 cannot move horizontally. Move the L-shaped lever 17, which causes one end of the pawl 10 to disengage from the tooth groove of the ratchet 9. At this point, the ratchet 9 is freed from the constraint of the pawl 10, and the connecting rod 6 is also freed. Then, rotate the U-shaped support rod 7. The rotation of the U-shaped support rod 7 causes the leg support block 8, which is symmetrically connected to the outer wall, to rotate synchronously. Place the patient's leg in the concave groove on the upper surface of the leg support block 8. Then, fine-tune the tilt angle of the U-shaped support rod 7, and then release the L-shaped lever 17. Since the pawl 10 is connected to the slider 5 via a spring shaft... One side of the pawl 10 is rotated and connected. Under the restoring force of the spring, one end of the pawl 10 abuts against the tooth groove of the ratchet 9, and the ratchet 9 cannot rotate. Consequently, the connecting rod 6 cannot rotate, and the U-shaped support rod 7 cannot rotate towards the patient. The angle of the U-shaped support rod 7 is restricted. By adjusting the tilt angle of the U-shaped support rod 7, the leg elevation effect for different patients can be achieved. After use, the U-shaped support rod 7 is rotated away from the patient, so that the U-shaped support rod 7 rotates to the bottom of the electric operating table body 1 and no longer occupies the space of the bed surface.

[0033] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
