Description

Technical Field

[0001] This utility model relates to the field of operating table technology, and in particular to an electric operating table leg plate device. Background Technology

[0002] An operating table is an essential tool for doctors during surgery, serving as a crucial piece of equipment for patient placement and providing a more convenient surgical environment. Based on their intended use, operating tables are categorized into multi-functional operating tables, gynecological operating tables, and orthopedic operating tables, among others. According to the movement mechanism of the operating table surface, they can be broadly classified into three types: electrically driven, hydraulically driven, and manually driven.

[0003] As a core support device in clinical surgery, the electric operating table is designed to adapt to the position adjustment needs of different surgical procedures. It usually includes core structures such as base, lifting components, headboard, backboard, waistboard, buttocksboard and push board; among them, the legboard is a key component related to the support of the patient's lower limbs and is mainly used to support the patient's legs.

[0004] In 2020, the applicant in this case applied for a "leg plate device for operating tables," which includes connecting rod one, connecting rod two, a leg plate cylinder end pin, a leg plate connecting pin, a connecting rod pin, a leg plate frame, and a leg plate cylinder. When the leg plate cylinder extends, the piston rod pushes connecting rod one to rotate counterclockwise, which, through the drive of the leg plate connecting pin, causes the leg plate frame to fold upward at the end of the hip plate frame. When the piston rod of the leg plate cylinder retracts into the cylinder, it causes the leg plate to fold downward at the end of the hip plate frame. In practical applications, it has been found that the position adjustment is not flexible enough in situations such as orthopedic lower limb surgery, urological surgery, and obstetric and gynecological surgery, affecting the convenience of operation. Therefore, how to design a compact electric operating table leg plate device that meets the requirements of flexible position adjustment is a technical problem that urgently needs to be solved in this case. Utility Model Content

[0005] To address the above problems, this utility model provides a compact electric operating table leg plate device that allows for flexible position adjustment.

[0006] The technical solution of this utility model is: The electric operating table leg support device includes: A locking seat is used to snap into the leg plate fixing seat, and a first connecting port is provided at the front; The first adjusting arm has connecting tongues at both ends; The second adjusting arm has a second connecting port at its end; the connecting tongues at both ends are respectively hinged to the first connecting port and the second connecting port. The pressure plate has several guide rods in the middle of its top surface, and several guide holes adapted to the guide rods are provided at the bottom of the first adjusting arm. The two ends of the top surface of the pressure plate are respectively provided with lower pressing blocks that are fixedly connected, and the top of the lower pressing blocks is provided with lower teeth. By pressing the pressure plate towards the first adjusting arm, the distance between the first connection port and the second connection port is reduced, and the first adjusting arm is fixed to the locking seat and the second adjusting arm respectively. The leg plate is fixedly installed on the top surface of the second adjusting arm.

[0007] Specifically, the second adjusting arm has an L-shaped structure.

[0008] Specifically, the locking seat has an F-shaped cross-section.

[0009] Specifically, a first connection port is formed between the first upper pressure tongue and the first lower pressure tongue of the locking seat.

[0010] Specifically, the thickness of the first downward pressing tongue is less than the thickness of the first upward pressing tongue.

[0011] Specifically, the bottom of the first pressing tongue is provided with a first pressing block that is fixedly connected; The bottom surface of the first upper pressure block is provided with a first upper tooth that meshes with the lower tooth.

[0012] Specifically, a second connection port is formed between the second upper pressure tongue and the second lower pressure tongue of the second adjusting arm.

[0013] Specifically, the thickness of the second lower pressing tongue is less than the thickness of the second upper pressing tongue.

[0014] Specifically, the bottom of the second lower pressing tongue is provided with a second upper pressing block that is fixedly connected; The bottom surface of the second upper pressure block is provided with a second upper tooth that meshes with the lower tooth.

[0015] Specifically, the pressing block has a circular structure.

[0016] This invention addresses the lack of flexibility in adjusting the position of traditional leg plate devices by achieving a dual improvement in structural compactness and ease of adjustment through multi-dimensional structural optimization. The connecting post at the tail of the locking seat quickly engages with the leg plate fixing seat, ensuring a stable assembly between the device and the operating table, preventing loosening or displacement during surgery, and simplifying the assembly and disassembly process, thus improving pre- and post-operative operational efficiency. The connecting tongues at both ends of the first adjusting arm are respectively hinged to the connection ports of the locking seat and the second adjusting arm, forming a multi-segment hinge structure. This breaks through the limitations of traditional single-movement mechanisms, allowing for flexible adjustment of the leg plate position to meet the diverse leg positioning needs of various surgeries, including orthopedic lower limb surgeries, urological surgeries, and obstetrics and gynecology surgeries. The guide rod on the top surface of the pressure plate precisely matches the guide hole of the first adjusting arm, ensuring no displacement during the pressing and releasing process of the pressure plate. The threaded locking handle drives the pressure plate movement, and the lower teeth of the lower pressure block engage with the corresponding upper teeth to lock the device, making the overall device more compact and allowing for instant locking at any adjustment position with higher adjustment precision, thus solving the pain point of insufficient adjustment flexibility in traditional devices.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The following is for reference. Figure 1-6 Describe the fundamental utility model; The electric operating table leg support device includes: The locking seat 100 has a fixed connecting post 110 at its rear end, which is used to snap into the leg plate fixing seat 700. The connecting post 110 has an F-shaped cross-section and a first connecting port at the front. After the connecting post 110 is fitted into the leg plate fixing seat, the two can be fixed using conventional connectors, achieving quick and stable assembly of the leg plate device and the operating table body. This prevents the device from loosening or shifting during surgery, simplifies the assembly and disassembly process, and improves the efficiency of preoperative preparation and postoperative cleaning. Figure 1 , 6 As shown, the top end of the leg plate fixing seat 700 is hinged to the hip frame, and the bottom end is hinged to the drive cylinder. By extending the drive cylinder, the leg plate fixing seat 700 is flipped upward around the upper hinge point, thereby driving the locking seat 100 to flip upward. The first adjusting arm 200 has connecting tongues 210 at both ends; The second adjusting arm 300 has an L-shaped structure and a second connection port at one end; the connecting tongues 210 at both ends are respectively hinged to the first connection port and the second connection port. A pressure plate 400 has several guide rods 410 in the center of its top surface, and several guide holes adapted to the guide rods 410 are provided at the bottom of the first adjusting arm 200. Lower pressing blocks 420 are fixedly connected to both ends of the top surface of the pressure plate 400. The lower pressing blocks 420 have a circular structure and a toothed portion at their top. By pressing the pressure plate 400 against the first adjusting arm 200, the distance between the first and second connecting ports is reduced, thus fixing the first adjusting arm 200 to the locking seat 100 and the second adjusting arm 300 respectively. The pressure plate 400 has a through hole in the middle, and a locking handle 600 is provided on the through hole. The locking handle 600 is connected to the bottom of the first adjusting arm 200 by a thread. Rotating the locking handle 600 moves the pressure plate 400 toward the first adjusting arm 200, thereby causing a pair of first upper teeth to mesh with the corresponding first upper teeth and second upper teeth, thus locking the first adjusting arm 200. After the leg plate position is adjusted in multiple stages, it can be quickly locked, adapting to the different needs of patients' leg positions for different surgical procedures such as orthopedic lower limb surgery, urological surgery, and obstetric and gynecological surgery.

[0022] The leg plate 500 is fixedly mounted on the top surface of the second adjusting arm 300 and rotates with the second adjusting arm 300.

[0023] A first connection port is formed between the first upper pressure tongue and the first lower pressure tongue of the locking seat 100.

[0024] The thickness of the first lower pressing tongue is less than the thickness of the first upper pressing tongue, which makes it easier for the first lower pressing tongue to press the connecting tongue 210 upward and fix the first adjusting arm 200 to the locking seat 100.

[0025] The bottom of the first pressing tongue is provided with a first upper pressing block 120 that is fixedly connected; The bottom surface of the first upper pressure block 120 is provided with a first upper tooth that meshes with the lower tooth.

[0026] A second connection port is formed between the second upper pressure tongue and the second lower pressure tongue of the second adjusting arm 300.

[0027] The thickness of the second downward pressing tongue is less than the thickness of the second upward pressing tongue.

[0028] The bottom of the second pressing tongue is provided with a fixedly connected second upper pressing block 310; The bottom surface of the second upper pressure block 310 is provided with a second upper tooth that meshes with the lower tooth.

[0029] This electric operating table leg plate device addresses the lack of flexibility in position adjustment of traditional leg plate devices by achieving a dual improvement in structural compactness and ease of adjustment through multi-dimensional structural optimization. The connecting post 110 at the tail of the locking seat 100 quickly snaps into the leg plate fixing seat 600, simplifying the assembly and disassembly process and improving pre- and post-operative operational efficiency. The connecting tongues 210 at both ends of the first adjusting arm 200 are respectively hinged to the connection port of the locking seat 100 and the second adjusting arm 300, forming a multi-segment hinge structure. This overcomes the problem of traditional single-direction rotation and poor flexibility, and can adapt to the differentiated leg positioning needs of various surgeries such as orthopedic lower limb surgery, urology, and obstetrics and gynecology.

[0030] The guide rod 410 on the top surface of the pressure plate 400 is precisely matched with the guide hole of the first adjusting arm 200 to ensure that the pressure plate 400 does not deviate during the pressing or releasing process; the locking handle 600 with threaded connection drives the pressure plate 400 to move, and the lower teeth of the lower pressure block 420 engage with the corresponding upper teeth to lock, making the whole device more compact, and can be locked instantly at any adjustment position, with higher adjustment accuracy, solving the pain point of insufficient adjustment flexibility of traditional devices.
