Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically a surgical table tilting mechanism and a surgical table. Background Technology

[0002] Tilting the operating table is a common method of patient positioning during surgery, especially with the development of surgical techniques, the demand for adjustable operating table tilt angles is increasing. Currently, many structures and methods exist to achieve this angle adjustment, but most suffer from structural complexity and limited adjustment angles.

[0003] Chinese patent CN108100939B discloses a device capable of tilting a tabletop at a large angle, comprising a motor, a lead screw mechanism, a column, a connecting rod, and a tabletop. The lead screw mechanism and motor are located on the front side of the column. The motor drives the lead screw in the lead screw mechanism to rotate. The two ends of the connecting rod are hinged to a lifting nut in the lead screw mechanism and the front side of the tabletop, respectively. The rear side of the tabletop is hinged to the rear side of the column. A motor reducer drives a gear set to rotate, and the screw-nut structure converts the rotational motion into linear motion. The lifting block rises, pushing the connecting rod and causing the rotating shaft to rotate around the axis, achieving a tilt of the tabletop at one angle. The same mechanism is used on the reverse side for tilting at another angle. This mechanism requires not only a motor reducer but also gear transmission and screw-nut transmission, resulting in multiple transmission stages, significant energy loss, complex structure, and high manufacturing costs.

[0004] Chinese utility model CN218853027U discloses a tilting and moving unit for an electric operating table, including a bed frame with a headrest board hinged to one end. A control button is located on one side of the bed frame. A tilting mechanism is located on the lower surface of the bed frame, and an electric lifting platform is located below the tilting mechanism. A stable base plate is located at the bottom of the electric lifting platform. Grooves are formed on both sides of the bed frame, and a through hole is formed on one side of each groove. A linkage rod is inserted through the through hole, and a fixing column is located on one side of the through hole. A fixing frame is located at one end of the linkage rod, and a driven gear is mounted on the linkage rod. This tilting and moving unit can tilt forward, backward, left, and right, but tilting requires the linkage of some hydraulic rods, and precise control is required over the extension and retraction distances of each hydraulic rod.

[0028] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] like Figure 1 As shown, an operating table tilting mechanism includes a left-right tilting drive 1 and a left-right tilting frame 4; a front-back tilting drive 11 and a front-back tilting frame 5.

[0031] The front and rear tilting frame 5 consists of four frames, namely the first frame 5-1, the second frame 5-2, the third frame 5-3, and the fourth frame 5-4.

[0032] The left and right tilting frame 4 is composed of four frames, namely the first frame 4-1, the second frame 4-2, the third frame 4-3, and the fourth frame 4-4.

[0033] The first frame 5-1 of the front-to-back tilt frame is parallel to the first frame 4-1 of the left-to-right tilt frame; the second frame 5-2 of the front-to-back tilt frame is parallel to the second frame 4-2 of the left-to-right tilt frame; the third frame 5-3 of the front-to-back tilt frame is parallel to the third frame 4-3 of the left-to-right tilt frame; the fourth frame 5-4 of the front-to-back tilt frame is parallel to the fourth frame 4-4 of the left-to-right tilt frame.

[0034] The support ring of the left and right tilting drive 1 is hinged to the left and right tilting hinge seat 1-2 of the upper column 12, and the support ring of the front and rear tilting drive 11 is hinged to the front and rear tilting hinge seat 11-2 of the upper column 12. The left and right tilting hinge seat 1-2 and the front and rear tilting hinge seat 11-2 are respectively arranged on adjacent surfaces of the upper column 12.

[0035] The telescopic rod of the left and right tilting drive 1 has a fork-shaped rod head 1-1, which clamps the first rotating shaft 2. The first rotating shaft 2 and the second rotating shaft 3 are rotatably connected in a cross shape in the middle. The two ends of the second rotating shaft 3 are connected to the first frame 4-1 of the left and right tilting frame through bearings.

[0036] The telescopic rod of the forward and backward tilting drive 11 has a ring rod head 11-1 at its head. The ring rod head 11-1 passes through the fifth rotating shaft 10. The two ends of the fifth rotating shaft 10 are connected to the second frame 4-2 of the left and right tilting frame through connecting seats.

[0037] The first frame 5-1 of the front and rear tilting frame and the third frame 5-3 of the front and rear tilting frame are rotatably connected to the top mounting seat of the upper column 12 via the fourth rotating shaft 9, and the second frame 5-2 of the front and rear tilting frame and the fourth frame 5-4 of the front and rear tilting frame are rotatably connected to the second frame 4-2 of the left and right tilting frame and the fourth frame 4-4 of the left and right tilting frame via the third rotating shaft 7.

[0038] There are two third pivots 7 and two fourth pivots 9. The third pivot 7 is fixed to the front and rear tilting frame 5 by locking screws 6, and the fourth pivot 9 is fixed to the front and rear tilting frame 5 by locking screws 8.

[0039] Both the left-right tilting drive 1 and the front-back tilting drive 11 are hydraulic cylinders. The support ring of the hydraulic cylinder is hinged to the left-right tilting hinge seat 1-1 of the upper column 12 using a ball bearing. This hinged connection ensures that when the extension rod of the hydraulic cylinder extends or retracts, the body of the hydraulic cylinder can move closer to or further away from the upper column 12. Similarly, the hydraulic cylinder support ring of the front-back tilting drive 11 is also hinged to the front-back tilting hinge seat 11-2 of the upper column 12 using a ball bearing. This hinged connection ensures that when the extension rod of the hydraulic cylinder extends or retracts, the body of the hydraulic cylinder can move closer to or further away from the upper column 12.

[0040] Mounting seats are provided on the top of the first and third sides of the upper column 12; the top height of the second and fourth sides is lower than that of the first and third sides.

[0041] The lower part of the first side of the upper column 12 is provided with a left-right tilting hinge seat 1-2; the lower part of the second side is provided with a front-back tilting hinge seat 11-2.

[0042] The first rotating shaft 2 passes through the middle of the second rotating shaft 3, forming a cross. The two ends of the second rotating shaft 3 are connected to two connecting seats extending from the first frame 4-1 of the left and right tilting frames using bearings, and the second rotating shaft 3 can rotate. There are two third rotating shafts 7, arranged opposite each other. One connects the second frame 5-2 of the front and rear tilting frames and the second frame 4-2 of the left and right tilting frames; the other connects the fourth frame 5-4 of the front and rear tilting frames and the fourth frame 4-4 of the left and right frames. The third rotating shaft 7 is rotatably connected to the left and right tilting frames 4. At the connection point with the front and rear tilting frames 5, a flat section needs to be provided on the third rotating shaft 7, and it is fixed with locking screws 6 to prevent rotation. There are two fourth rotating shafts 9, arranged opposite each other. One connects the first frame 5-1 of the front and rear tilting frames to the mounting seat at the top of the column 12; the other connects the third frame 5-3 of the front and rear tilting frames to the mounting seat at the top of the column. The fourth rotating shaft 9 is rotatably connected to the mounting seat, and at the connection point with the front and rear tilting frames 5, a flat section needs to be provided and it is fixed with locking screws 8.

[0043] The working process of this utility model is as follows:

[0044] like Figure 1 As shown, the telescopic rods of the left and right tilt drive 1 and the front and rear tilt drive 11 extend to the same length, so that the left and right tilt frame 4 and the front and rear tilt frame 5 are horizontal.

[0045] like Figure 2As shown, the telescopic rod of the forward and backward tilting drive 11 retracts, the second rotating shaft 3 rotates around the first rotating shaft 2, the fourth rotating shaft 9 rotates around the mounting seat at the top of the column, and the fifth rotating shaft 10 rotates in the annular rod head 11-1, causing the forward and backward tilting frame 5 and the left and right tilting frame 4 to rotate around the column by a certain angle (e.g., 38°). At this time, the left and right tilting drive 1 maintains the extension distance of the telescopic rod unchanged. The forward and backward tilting frames are connected to the column, so the forward and backward tilting drive only needs to bear the axial force. The left and right tilting hydraulic cylinders bear a small portion of the lateral force when the first and second rotating shafts rotate. After the movement stops, the main load-bearing component is the frame, which improves the safety of the mechanism.

[0046] like Figure 3 As shown, the telescopic rod of the forward and backward tilting drive 11 extends, and the movement angle of the table tilting mechanism is related to... Figure 2 on the contrary.

[0047] like Figure 4 As shown, the forward and backward tilting drive keeps the extension length of the telescopic rod unchanged, while the left and right tilting drive retracts the telescopic rod, causing the left and right tilting frame 4 to rotate around the third pivot 7 by a certain angle (such as 28°).

[0048] like Figure 5 As shown, this represents rotation in another direction besides the left and right directions, and its rotation direction is the same as... Figure 4 on the contrary.

[0049] The operating table surface can be connected to the left and right tilting frames to achieve table tilting. Note that... Figures 2 to 5 This only demonstrates the extension or retraction of a single hydraulic cylinder piston, but its application is not limited to controlling a single hydraulic cylinder. For example, by tilting forward or backward to a certain angle, controlling the left or right tilting hydraulic cylinder can achieve a combined tilt in another direction at that angle. For instance, when tilting left or right by 28°, forward or backward tilting can be achieved within a range of 23°.
