Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a movable platform for lithotomy without disassembly. Background Technology

[0002] The lithotomy position is a core surgical position in departments such as gynecology, urology, and colorectal surgery. It requires specialized support equipment to keep the patient's legs abducted and knees flexed to fully expose the surgical field and ensure the smooth progress of the procedure. Currently, the most widely used lithotomy position support device in clinical practice is the lithotomy leg rest, which needs to be closely integrated with the operating table. The operation of the leg support in the lithotomy position is characterized by multiple steps and high dependence on manual labor. Before the operation, each component of the leg support needs to be assembled into the preset position on the operating table. After assembly, medical staff need to work together to remove the components at the end of the operating table. Since the end of the table is mostly made of metal, 2-3 medical staff need to move it simultaneously. After the operation, the disassembled end of the operating table needs to be realigned with the operating table body, and then the patient's legs are slowly moved from the leg support to the support surface at the end of the table. Finally, the leg support components are removed. The entire process requires repeated adjustments to ensure the patient's limb comfort and safety.

[0003] The existing lithotomy leg frame is cumbersome to use. Preoperative assembly of the leg frame and removal of the foot of the bed, as well as postoperative reassembly and removal of the leg frame, prolong the surgical connection time and are time-consuming and labor-intensive for medical staff. In departments with a high volume of surgeries, it may even affect the efficiency of surgical scheduling. Utility Model Content

[0004] (a) Technical problems to be solved In view of the shortcomings of the existing technology, this utility model solves the problem that the existing lithotomy leg frame is cumbersome to operate, and that assembling the leg frame and removing the foot of the bed before surgery, as well as reassembling the foot of the bed and removing the leg frame after surgery, prolongs the connection time of surgery and is time-consuming and labor-intensive for medical staff.

[0005] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] A movable lithotomy position platform that does not require disassembly includes: an operating table extension component connected to the end of an operating table, the operating table extension component including a first extension plate and a second extension plate, one end of the second extension plate being hinged to the end of the first extension plate; two lithotomy position legs symmetrically mounted on the top of the operating table extension component; a slide rail is provided on the top of the operating table extension component, and a sliding seat adapted to the slide rail is provided at the bottom of the lithotomy position legs, the lithotomy position legs can reciprocate along the length direction of the operating table extension component; when the lithotomy position legs move along the slide rail to the first extension plate, the second extension plate can be folded downward around the hinge point to the bottom of the first extension plate.

[0007] In one embodiment, the operating table extension component further includes a hydraulic rod, one end of which is mounted on the bottom of the first extension plate and the other end of which is mounted on the bottom of the second extension plate. The hydraulic rod is configured to drive the second extension plate to rotate about its hinge point with the first extension plate, so that the second extension plate and the first extension plate remain in a coplanar horizontal state, or folded to a storage state that fits against the bottom of the first extension plate.

[0008] Preferably, a mounting base is fixed to the bottom of the first extension plate, and a connecting base is fixed to the bottom of the second extension plate; one end of the hydraulic rod is rotatably connected to the mounting base via a pin, and the other end of the hydraulic rod is rotatably connected to the connecting base via a pin.

[0009] In one embodiment, the top wall of the slide is provided with a sliding hole, which is opened on the top surface of the first extension plate and the second extension plate, and the stone cutting leg bracket passes through the sliding hole and extends upward.

[0010] In one embodiment, the width of the slide is greater than the width of the slide hole, the width of the sliding seat is adapted to the slide groove, and the diameter of the stone cutting leg is smaller than the width of the slide hole.

[0011] In one embodiment, the lithotomy leg support includes: a first nut, threaded onto the rod of the lithotomy leg support, tightening the first nut to lock the lithotomy leg support onto the operating table extension component; a telescopic rod, the top of the lithotomy leg support having a telescopic groove extending in a vertical direction, the telescopic rod being slidably fitted into the telescopic groove; and a support plate, installed on the top of the telescopic rod for supporting the patient's legs.

[0012] Preferably, the rock-cutting leg frame further includes: a second nut, threaded onto the outer wall of the telescopic rod, and tightening the second nut can lock the telescopic rod onto the rock-cutting leg frame.

[0013] In one embodiment, it further includes: four support legs, which are arranged in a rectangular shape and fixedly installed at the bottom of the first extension plate.

[0014] In a preferred embodiment, the bottom end of the support leg is equipped with casters.

[0015] In a preferred embodiment, the operating table extension component further includes a connector mounted on one side of the first extension plate, wherein the operating table extension component is detachably connected to the end of the operating table via the connector.

[0016] (III) Beneficial Effects This invention provides a movable lithotomy position platform that does not require disassembly. Compared with existing technologies, it has the following advantages: The quick-connect design of the operating table extension component and the connecting parts eliminates the need to disassemble the original footboard components. The operating table extension component can be quickly assembled with the operating table via the connecting parts. The lithotomy position leg frame does not require temporary preoperative assembly; its position can be adjusted simply by the cooperation of the sliding seat and the slide rail. Postoperatively, the lithotomy position leg frame does not need to be removed from the bed, reducing overall operational steps. For consecutive lithotomy surgeries requiring the placement of the lithotomy position, this increases the turnover rate of operating tables and reduces the workload and intensity of medical staff in handling instruments before surgery. In the preoperative stage, the docking of the operating table and the positioning of the lithotomy position leg frame are achieved through quick-connect parts and sliding adjustments, respectively. In the postoperative stage, simply releasing the lithotomy position leg frame lock, unfolding the extension plate, and separating the connecting parts completes the equipment's return to its original position. The time spent connecting before and after a single surgery can be reduced. Especially in departments with high surgical volume, this reduces surgical delays caused by equipment operation, ensuring that surgical schedules proceed as planned. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. 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.

[0025] Reference Figure 1-5 A movable lithotomy position platform that does not require disassembly includes: an operating table extension component 100 connected to the end of the operating table, the operating table extension component 100 including a first extension plate 101 and a second extension plate 102, one end of the second extension plate 102 being hinged to the end of the first extension plate 101; two lithotomy position leg supports 200 symmetrically mounted on the top of the operating table extension component 100; a slide rail 103 is provided on the top of the operating table extension component 100, and a sliding seat 204 adapted to the slide rail 103 is provided at the bottom of the lithotomy position leg support 200; the lithotomy position leg support 200 can reciprocate along the length direction of the operating table extension component 100; when the lithotomy position leg support 200 moves along the slide rail 103 to the first extension plate 101, the second extension plate 102 can be folded downward around the hinge point to the bottom of the first extension plate 101.

[0026] Furthermore, the first extension plate 101 and the second extension plate 102 of the operating table extension component 100 are hinged. Utilizing the mechanical principle of a revolute joint, the second extension plate 102 can unfold and fold around the hinge point. When the second extension plate 102 is unfolded, it can form a continuous support surface together with the first extension plate 101 to meet the patient's needs for leg placement before and after surgery. When the second extension plate 102 is folded to the bottom of the first extension plate 101, it can reduce the space occupied by the extension component in the surgical operation area. The matching structure of the sliding seat 204 and the slide 103 ensures the stability of the lithotomy leg frame 200 during movement, allowing the lithotomy leg frame 200 to be moved to any position to meet the leg support position requirements of different surgeries.

[0027] The above technical solution can reduce the disassembly and installation of the operating table footboard during the use of the lithotomy leg support 200, shorten the connection time before and after surgery, and reduce the number of operation steps for medical staff in the preparation and closing stages of surgery. The lithotomy leg support 200 can be moved by the cooperation of the sliding seat 204 and the slide rail 103. Medical staff do not need to repeatedly adjust or assemble the lithotomy leg support 200. They only need to push the lithotomy leg support 200 to complete the position adjustment, which reduces the physical exertion of medical staff. At the same time, the symmetrically arranged lithotomy leg support 200 can adapt to the leg support needs of different patients and reduce the number of adjustments during the positioning process.

[0028] Reference Figure 2 In one embodiment, the operating table extension component 100 further includes a hydraulic rod 400, one end of which is mounted on the bottom of the first extension plate 101 and the other end of which is mounted on the bottom of the second extension plate 102. The hydraulic rod 400 is configured to drive the second extension plate 102 to rotate about its hinge point with the first extension plate 101, so that the second extension plate 102 and the first extension plate 101 remain in a coplanar horizontal state, or folded to a retracted state that fits against the bottom of the first extension plate 101.

[0029] Preferably, a mounting base 401 is fixed to the bottom of the first extension plate 101, and a connecting base is fixed to the bottom of the second extension plate 102; one end of the hydraulic rod 400 is rotatably connected to the mounting base 401 via a pin, and the other end of the hydraulic rod 400 is rotatably connected to the connecting base via a pin.

[0030] Furthermore, by utilizing the clearance fit between the pin and the mounting base 401 and the connecting base, the flexible rotation of both ends of the hydraulic rod 400 is achieved, ensuring that the extension and retraction of the hydraulic rod 400 can be smoothly converted into the relative rotation of the two extension plates. The mounting base 401 and the connecting base are respectively fixed to the bottom of the two extension plates, so that the force of the hydraulic rod 400 can be directly transmitted to the second extension plate 102. When the hydraulic rod 400 is in the extended state, the second extension plate 102 can form a continuous support surface together with the first extension plate 101. When the hydraulic rod 400 is in the retracted state, the second extension plate 102 can be folded to the bottom of the first extension plate 101.

[0031] In the above technical solution, the mounting base 401 and the connecting base can ensure that when the hydraulic rod 400 drives the first extension plate 101 and the second extension plate 102 to rotate relative to each other, the force at both ends is uniform and the transmission is stable, avoiding the extension plate posture adjustment being unsmooth due to loosening or jamming of the connection parts. The rotational connection achieved by the pin shaft can reduce the additional resistance during the extension and retraction of the hydraulic rod 400.

[0032] Reference Figure 1 and Figure 4In one embodiment, the top wall of the slide 103 is provided with a sliding hole 104, which is opened on the top surface of the first extension plate 101 and the second extension plate 102. The stone cutting leg 200 passes through the sliding hole 104 and extends upward. The width of the slide 103 is greater than the width of the sliding hole 104. The width of the sliding seat 204 is adapted to the slide groove. The diameter of the stone cutting leg 200 is smaller than the width of the sliding hole 104.

[0033] Furthermore, the matching of the sliding seat 204 and the sliding groove realizes the guidance and limitation of the movement of the rock cutting leg 200, which conforms to the guiding design logic of the linear motion pair in mechanical motion, ensuring that the rock cutting leg 200 moves in the preset direction. The structure of the slide 103 being wider than the slide hole 104 can form a lateral limitation on the sliding seat 204 through the side wall of the slide 103, preventing the sliding seat 204 from shifting laterally during movement. At the same time, the constraint of the slide hole 104 on the rock cutting leg 200 can further limit the radial sway of the rock cutting leg 200.

[0034] In the above technical solution, the sliding seat 204 is stably confined within the groove of the slide rail 103, preventing the sliding seat 204 from detaching from the top of the slide rail 103 during movement, thus ensuring the overall stability of the rock-cutting leg 200 during movement. The matching relationship between the diameter of the rock-cutting leg 200 and the width of the sliding hole 104 can reduce the frictional resistance of the rock-cutting leg 200 when moving within the sliding hole 104, making the movement of the rock-cutting leg 200 along the length direction of the extension component smoother, while avoiding jamming caused by dimensional deviation. The design that the width of the slide rail 103 is greater than the width of the sliding hole 104 can provide sufficient accommodation space for the sliding seat 204, ensuring that the sliding seat 204 is not blocked by the edge of the sliding hole 104 when moving within the groove.

[0035] Reference Figure 3 and Figure 5 In one embodiment, the lithotomy leg support 200 includes: a first nut 202, threaded onto the rod of the lithotomy leg support 200, tightening the first nut 202 to lock the lithotomy leg support 200 onto the operating table extension component 100; a telescopic rod 201, the top of the lithotomy leg support 200 having a telescopic groove extending in a vertical direction, the telescopic rod 201 being slidably fitted into the telescopic groove; a support plate 205, installed on the top of the telescopic rod 201 for supporting the patient's legs; and a second nut 203, threaded onto the outer wall of the telescopic rod 201, tightening the second nut 203 to lock the telescopic rod 201 onto the lithotomy leg support 200.

[0036] Furthermore, the first nut 202 engages with the threaded connection of the lithotomy leg bracket 200. Utilizing the self-locking characteristic of the threaded connection, the friction and pressure generated during tightening securely fix the lithotomy leg bracket 200 to the operating table extension component 100. This conforms to the design logic of threaded locking in mechanical fixation, achieving a detachable and stable fixation effect. The sliding fit of the telescopic rod 201 with the telescopic groove, based on the design principle of a linear sliding pair, allows the telescopic rod 201 to move along a preset vertical direction, ensuring the accuracy of the height adjustment direction. The second nut 203 engages with the threaded connection of the telescopic rod 201... Similarly, utilizing the self-locking principle of the thread, a rigid constraint is formed after the telescopic rod 201 is adjusted to its position, limiting its sliding and ensuring the reliability of the height lock. From the perspective of adapting to clinical application needs, the thread locking method is easy to operate, and medical staff can complete the fixation and height adjustment of the lithotomy leg support 200 without the need for additional tools, which meets the need for rapid position adjustment during surgery. The support plate 205 is designed to meet the actual needs of the patient's leg support, and the vertical height adjustment can adapt to the leg placement angle of patients of different heights and body types, meeting the support requirements of diverse surgical positions.

[0037] In the above technical solution, the first nut 202 can be set to quickly fix the lithotomy leg frame 200 by tightening after the lithotomy leg frame 200 moves to the target position along the operating table extension component 100. This prevents the lithotomy leg frame 200 from shifting due to external force during the operation and ensures the stability of the leg support position. The sliding cooperation between the telescopic rod 201 and the telescopic groove allows medical staff to adjust the length of the telescopic rod 201 extending out of the lithotomy leg frame 200 according to the patient's leg length and the required height of the surgical position, so that the height of the support plate 205 can be adapted to the support needs of different patients.

[0038] Reference Figure 1 In one embodiment, it further includes: four support legs 300, which are arranged in a rectangular shape and fixedly installed on the bottom of the first extension plate 101. Each support leg 300 is equipped with a caster wheel 301 at its bottom end.

[0039] Furthermore, the swivel wheel 301 is a swivel wheel 301 with a brake.

[0040] In the above technical solution, the four rectangularly distributed support legs 300 can evenly distribute the weight of the first extension plate 101 and the components above it to four support points, preventing the first extension plate 101 from undergoing local deformation or sagging due to concentrated force, thus ensuring the overall structural stability of the operating table extension component 100. The universal wheels 301 allow medical staff to move the operating table extension component 100 without carrying it, reducing the physical exertion when adjusting the position of the operating table extension component 100. At the same time, it facilitates flexible adjustment of the position of the operating table extension component 100 according to the placement of the operating table and the layout of the operating room. After the operating table extension component 100 moves to the target position, the universal wheels 301 with brakes can be locked by operating the brakes to prevent the operating table extension component 100 from shifting due to personnel collisions or equipment vibrations during the operation, thus ensuring the stability of the surgical operating environment.

[0041] Reference Figure 1 In a preferred embodiment, the operating table extension component 100 further includes a connector 105, which is installed on one side of the first extension plate 101, and the operating table extension component 100 is detachably connected to the end of the operating table via the connector 105.

[0042] Furthermore, the connector 105 adopts a detachable design. Based on the structural principle of quick assembly and disassembly in mechanical connections, it achieves precise engagement with the end of the operating table through a pre-set docking structure, such as a snap-fit ​​or pin structure. This ensures the structural strength after connection while simplifying the assembly and disassembly process. The connector 105 is fixedly connected to the first extension plate 101, and at the same time, it engages with the end of the operating table through a detachable connection. When it is necessary to combine the operating table extension component 100 with the operating table, assembly can be completed by docking the connector 105 with the end of the operating table. When it is necessary to separate the two, the connection can be released by operating the detachable structure of the connector 105, so that the operating table extension component 100 is detached from the end of the operating table. This allows the operating table extension component 100 to be quickly assembled or separated from the operating table without relying on disassembling the original components of the operating table.

[0043] In the above technical solution, the connection 105 allows the connection between the operating table extension component 100 and the end of the operating table to be made without disassembling the operating table itself, eliminating the steps of disassembling and assembling the end of the operating table in traditional operations, reducing the preparation and finishing time before and after surgery. The detachable connection method allows medical staff to flexibly decide whether to assemble the operating table extension component 100 according to the needs of surgery. When the lithotomy position is not needed, the extension component can be quickly separated from the operating table without affecting the normal use function of the operating table.

[0044] The following is a brief introduction to the operating principle and method of the movable platform for stone cutting without disassembly proposed in this application: First, the operating table extension component 100 is connected to the end of the operating table via the connector 105 on one side of the first extension plate 101. This can be achieved through a snap-fit ​​or pin mechanism for quick fixation, without disassembling the original components of the operating table. Simultaneously, the brakes on the universal wheels 301 at the bottom of the support legs 300 are unlocked, pushing the platform to adjust its position so that the operating table extension component 100 is coaxially aligned with the operating table. After adjustment, the universal wheels 301 are locked to fix the platform position. Next, the hydraulic rod 400 is extended. The two ends of the hydraulic rod 400 rotate via pins in the mounting base 401 at the bottom of the first extension plate 101 and the connector at the bottom of the second extension plate 102, respectively. This drives the second extension plate 102 to rotate upwards around its hinge point with the first extension plate 101 until the second extension plate 102 and the first extension plate 101 form a coplanar horizontal state, creating a continuous support surface. The patient is placed on the operating table, with their legs resting on the first extension plate 101 and the second extension plate 102.

[0045] In the intraoperative adaptation phase, first loosen the first nut 202 and push the two lithotomy leg supports 200 along the slide 103 toward the first extension plate 101 until the lithotomy leg supports 200 are in the area of ​​the first extension plate 101. Tighten the first nut 202 to lock the lithotomy leg supports 200 onto the first extension plate 101. Then place both legs on the two support plates 205 respectively. Loosen the second nut 203 and adjust the extension length of the telescopic rod 201 in the telescopic groove of the lithotomy leg support 200 according to the patient's leg length and surgical position requirements, so that the height of the support plate 205 is adapted to the support angle of the patient's legs. After adjustment, tighten the second nut 203 to lock the position of the telescopic rod 201. Then press down on the second extension plate 102 to control the hydraulic rod 400 to retract and drive the second extension plate 102 to rotate downward around the hinge point until it fits the bottom of the first extension plate 101 for storage, reducing the space occupied by the extension components in the surgical operation area to fully expose the surgical field of vision.

[0046] After the surgery, pull up the second extension plate 102. The hydraulic rod 400 drives the second extension plate 102 to rotate upwards until it is coplanar with the first extension plate 101. Loosen the first nut 202 and move the patient's legs from the support plate 205 to the support surface of the extension component. Assist the patient to turn over or transfer to the operating table. Then, operate the detachable structure of the connector 105 to disconnect the extension component from the operating table, unlock the brake of the universal wheel 301, and push the platform away from the operating table area to complete the postoperative cleaning and equipment return.

[0047] In summary, compared with the prior art, the movable platform for the stone cutting position that does not require disassembly proposed in this application has the following beneficial effects: The operating table extension component 100 and the connecting piece 105 of the operating table are designed for quick docking, eliminating the need to disassemble the original footboard components of the operating table. The operating table extension component 100 can be quickly assembled with the operating table through the connecting piece 105. The lithotomy leg frame 200 does not require temporary assembly before surgery; its position can be adjusted simply by the cooperation of the sliding seat 204 and the slide rail 103. After surgery, the lithotomy leg frame 200 does not need to be removed from the bed, reducing the overall operation steps. For consecutive lithotomy surgeries that require the placement of the lithotomy leg frame, the turnover rate of the operating table can be improved, while reducing the workload and intensity of medical staff in moving and placing instruments before surgery.

[0048] In the preoperative stage, the docking of the operating table and the positioning of the lithotomy leg frame 200 are achieved through quick connector 105 and sliding adjustment, respectively. In the postoperative stage, the equipment can be returned to its original position simply by releasing the locking of the lithotomy leg frame 200, unfolding the extension plate, and separating the connector 105. The connection time before and after a single operation can be reduced. Especially in departments with a high volume of surgeries, it can reduce surgical delays caused by equipment operation and ensure that the surgical schedule proceeds as planned.
