Body position adjusting device for a surgical bed

Abstract

The body position adjusting device of a surgical bed relates to the technical field of surgical beds. It comprises a bottom plate, an adjusting plate and a lifting part. The lifting part comprises a rectangular frame, a lead screw and a rotating shaft. Through the transmission structure of "rotating shaft-gear-lead screw", medical staff can drive the second gear to mesh with the first gear by rotating the rotating shaft, and then drive the lead screw to rotate, so as to realize the precise lifting of the lifting plate. Finally, through the cooperation of the top rod and the sliding block connecting seat, the adjusting plate is tilted around the hinge point. The whole adjusting process is stable in transmission and labor-saving in operation. Compared with the operation mode of manually assisting the patient to lift the part by medical staff on the existing flat bed surface, the device replaces manual operation with mechanical transmission, not only reduces the physical consumption of medical staff, but also realizes precise control of the inclination angle through the precision of the lead screw transmission, so that the patient's operating part is in the most comfortable operating position of medical staff, greatly improving the convenience and efficiency of surgical operation.

Description

Technical Field

[0001] This utility model relates to the field of operating table technology, and in particular to a body position adjustment device for an operating table. Background Technology

[0002] The operating table is a core piece of diagnostic and treatment equipment in medical institutions. As the core platform for surgical procedures, its performance directly affects the safety, accuracy, and patient comfort of the surgery. It is widely used in various departments such as surgery, orthopedics, and obstetrics and gynecology, and is a key infrastructure for enabling patient positioning and assisting doctors in performing surgical procedures. With the development of medical technology, the operating table has evolved from an early simple support tool into an intelligent device integrating mechanical, hydraulic, and electronic controls.

[0003] The core structure of an operating table includes a bed frame, a lifting and adjustment system, a tabletop assembly, and a control system. The bed frame is made of high-strength stainless steel or aluminum alloy to ensure load-bearing stability, while also being corrosion-resistant, easy to clean, and meeting medical sterility requirements. The lifting and adjustment system is mostly hydraulically driven, enabling precise bed height adjustment to meet the needs of different surgical positions and surgeons' operating heights. Existing operating tabletops are mostly assembled from flat panels with a removable mattress. This type of operating table cannot meet the operational needs of medical staff when a certain area needs to be raised for treatment (suturing, surgery, etc.), reducing the convenience of operation. Therefore, how to meet the height adjustment requirements based on existing operating tables is a pressing technical problem that needs to be solved in this case. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a surgical bed position adjustment device that meets the needs of raising the operating table based on the existing surgical bed.

[0005] A patient positioning device for an operating table, comprising: The base plate is detachably and fixedly mounted on the operating table via connectors. An adjustment plate, one side of which is hinged to the base plate, and the other side which is adjustable above the base plate via a tilt angle adjustment assembly; the tilt angle adjustment assembly includes: The lifting unit includes a rectangular frame, a lead screw, and a rotating shaft; the rectangular frame is fixedly disposed in the middle of the base plate; the lead screw and the rotating shaft are vertically parallel to each other on the rectangular frame; a second gear is fixedly connected to the rotating shaft; a first gear is fixedly connected to the lead screw and meshes with the second gear; a lifting plate is disposed inside the rectangular frame and is slidably disposed up and down by the lead screw; a slider connecting seat is disposed on the lifting plate and is hinged to the lifting plate by a top rod.

[0006] The slide rail is fixedly mounted on the back of the adjusting plate; the slider connecting seat is slidably connected to the slide rail.

[0007] Specifically, the top rod is fixedly connected to the top of the lifting plate.

[0008] Specifically, the top rod and the slider connecting seat are hinged by a pin.

[0009] Specifically, the adjustment plate is tilted above the base plate.

[0010] Specifically, the adjustment plate is planar.

[0011] Specifically, the adjustment plate has an arc-shaped structure, with the middle part concave inward toward the bottom plate or convex outward in the opposite direction.

[0012] Specifically, the base plate and the adjustment plate are connected by a hinge assembly.

[0013] Specifically, the hinge assembly includes: The connecting column is fixedly installed at the front end of the base plate; The support base is fixedly connected to the adjustment plate at the back and hinged to the connecting column at the front.

[0014] Specifically, the back of the adjustment plate is provided with a groove that matches the support base.

[0015] Specifically, the lead screw has multiple telescopic rods arranged parallel to it on its side; The telescopic rod is vertically installed on the top surface of the base plate, and an auxiliary connecting seat is provided at the top with a hinge. The auxiliary connecting seat is connected to the adjusting plate through an auxiliary slide rail.

[0016] This invention utilizes a "rotating shaft-gear-lead screw" transmission structure, allowing medical personnel to drive the second gear to mesh with the first gear by rotating the rotating shaft. This, in turn, drives the lead screw to rotate, achieving precise raising and lowering of the lifting plate. Finally, the cooperation between the push rod and the slider connecting seat pushes the adjusting plate to tilt around the hinge point. The entire adjustment process is stable and effortless. Compared to existing flatbed beds that require manual assistance from medical personnel to elevate the patient's body, this device replaces manual operation with mechanical transmission. This not only reduces the physical exertion of medical personnel but also allows for precise control of the tilt angle through the precision of the lead screw transmission, placing the patient's body in the most comfortable operating position for the medical personnel, significantly improving the convenience and efficiency of surgical procedures.

Figure 1 As shown; The tilt angle adjustment component includes: Lifting section, such as Figure 2 As shown, the system includes a rectangular frame 19, a lead screw 20, and a rotating shaft 25. The rectangular frame 19 is fixedly disposed in the middle of the base plate 11. The lead screw 20 and the rotating shaft 25 are vertically parallel to each other on the rectangular frame 19. A second gear 26 is fixedly connected to the rotating shaft 25. A first gear 24 is fixedly connected to the lead screw 20 and meshes with the second gear 26. After the rotating shaft 25 rotates, the second gear 26 rotates and meshes with the first gear 24, thereby driving the lead screw 20 to rotate. A lifting plate 21 is provided inside the rectangular frame 19 and is slidably disposed up and down by the lead screw 20. A slider connecting seat 23 is provided on the lifting plate 21 and is hinged to it by a top rod 22.
