Description

TECHNICAL FIELD

[0001] The utility model relates to surgical bed technical field, more specifically, relate to a hidden waist bridge structure for surgical bed. BACKGROUND

[0002] As Figure 1 Indicated, surgical bed as patient support equipment (patients can lie on bed board 02), is indispensable key equipment for normal operation. Part of operation, need to raise the waist and abdomen locally, for this, the surgical bed body will be designed waist bridge structure alone. The main components of waist bridge structure are the upper waist bridge plate 01, the support structure on both sides and the transmission mechanism for driving the waist bridge plate 01 to lift. Because of the demand of perspective photograph, the section of bed body support 03 is relatively small, cannot accommodate too many transmission parts, at present, the waist bridge structure of most surgical beds is manually lifted. At the same time, in order to ensure the horizontal lifting of waist bridge plate 01, the left and right inclination will not be generated during the lifting process, the transmission mechanism on both sides is required to move synchronously, and the manual waist bridge structure will have a transmission rod connecting the transmission structure on both sides.

[0003] Manual waist bridge needs medical staff to manually lift the waist bridge plate 01, which is time-consuming and laborious under the condition of the patient above, and the existence of transmission rod will produce additional shadow area during perspective photograph, which will affect the operation, and the current manual waist bridge structure is gradually replaced by electric waist bridge structure.

[0004] Figure 2 And Figure 3 It is the existing electric waist bridge structure. The support rod 04 generally adopts rack or screw 05 etc. linear motion parts. The waist bridge motor 06 is generally composed of motor and speed reducer two parts, and most of them adopt standard small DC speed reducer motor. This structure can completely hide the waist bridge motor 06 part in the bed body support 03, and the finished product speed reducer motor can be purchased, so the cost is low, and it is widely used.

[0005] However, because the lifting distance of waist bridge generally exceeds the height of bed body support 03, and the support rod 04 and the waist bridge motor 06 need the necessary meshing height, when the waist bridge plate 01 is not lifted, the support rod 04 will be extended below the bed body support 03. In this way, when the bed body is translated or used with C arm photographing, the lower part of the support rod 04 may collide with other equipment, affect each other and even damage the equipment. At the same time, the exposed part of the waist bridge motor 06 cannot be effectively shielded, which is particularly conspicuous, affecting the overall appearance of the surgical bed.

[0042] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of protection of the present utility model.

[0043] The core of the present utility model is to provide a hidden waist bridge structure for a surgical bed, which not only compresses the height of the whole electric waist bridge structure to hide it in the bed body support, but also avoids affecting the translation of the electric waist bridge structure or the mutual influence when the electric waist bridge structure is used with other equipment.

[0044] Please refer to Figure 4 and Figure 5 , wherein, Figure 4 is a structural schematic view of the hidden waist bridge structure for a surgical bed provided by the present utility model; Figure 5 is a structural schematic view of the hidden waist bridge structure for a surgical bed from another perspective.

[0045] The present embodiment provides a hidden waist bridge structure for a surgical bed, which comprises:

[0046] a waist bridge plate 1;

[0047] a bed plate 3;

[0048] a bed body support 4 arranged at the opposite sides of the bottom of the bed plate 3;

[0049] a driving device 5 arranged horizontally;

[0050] a worm connected with the output shaft of the driving device 5;

[0051] a worm wheel 6 arranged in transmission cooperation with the worm;

[0052] a gear transmission assembly 7 arranged in meshing cooperation with the worm wheel 6;

[0053] a support rod 2 arranged vertically, which comprises an inner screw rod 21 and an outer screw rod 22 threadedly connected with the inner screw rod 21, the bottom of the outer screw rod 22 is sleeved with the gear transmission assembly, and the top of the inner screw rod 21 is provided with the waist bridge plate 1;

[0054] The driving device 5, the worm, the worm wheel 6 and the gear transmission assembly 7 are arranged in each bed body support 4, and the inner screw rod 21 is connected with the bottom side of the waist bridge plate 1 through the bed body support 4.

[0055] It needs to be explained that the outer screw rod 22 is threadedly connected with the inner screw rod 21, that is, the outer screw rod 22 is equivalent to a nut structure, and the inner screw rod 21 is equivalent to a lead screw structure, when the outer screw rod 22 rotates and does not lift, the inner screw rod 21 can be driven to not rotate and only lift to move, so as to realize the lifting driving of the waist bridge plate 1. The inner screw rod 21 is fixed with the waist bridge plate 1, so there is no relative movement between the inner screw rod 21 and the waist bridge plate 1.

[0056] In actual application, the shape, structure, size, position and the like of the waist bridge plate 1, the bed plate 3, the bed body support 4, the driving device 5, the worm, the worm gear 6, the gear transmission assembly 7 and the support rod 2 can be determined according to actual conditions and actual needs.

[0057] When the hidden waist bridge structure for a surgical bed is used, the driving device 5 is controlled to operate to drive the worm to rotate, the worm drives the worm gear 6 to rotate, the rotation of the worm gear 6 drives the gear transmission assembly 7 to rotate, and the rotation of the gear transmission assembly 7 drives the outer screw rod 22 to rotate, the rotation of the outer screw rod 22 drives the inner screw rod 21 to lift and move, and the lifting and moving of the inner screw rod 21 drives the waist bridge plate 1 to synchronously lift. The driving devices 5 on both sides of the bed plate 3 can be controlled to synchronously operate to make the two support rods 2 synchronously rise or fall, so as to prevent the waist bridge plate 1 from tilting due to uneven force.

[0058] The device increases the transmission structures such as the gear transmission assembly 7, the worm gear 6 and the worm between the support rod 2 and the driving device 5, so that the support rod 2 is separated from the driving device 5, and the support rod 2 is arranged as a screw rod transmission structure, so as to compress the necessary meshing height, compress the structure height of the entire driving device 5 to the height that can be put into the bed body support 4, so that the entire driving device 5 can be hidden in the bed body support 4, so as to realize the overall stealth effect when the waist bridge plate 1 is retracted, and avoid affecting the movement of the waist bridge plate 1 or affecting the mutual use of the waist bridge plate 1 and other equipment.

[0059] In summary, the hidden waist bridge structure for a surgical bed provided by the present application not only compresses the height of the entire electric waist bridge structure to be hidden in the bed body support, but also avoids affecting the translation of the electric waist bridge structure or avoiding affecting the mutual use of the electric waist bridge structure and other equipment.

[0060] In an embodiment, the driving device 5 includes a low-voltage direct-current motor and a speed reducer connected with the low-voltage direct-current motor, for example, a standard small direct-current speed reducer can be selected, and of course other types of motors and speed reducers can be selected according to actual needs.

[0061] In an embodiment, the gear transmission assembly 7 includes a first cylindrical gear and a second cylindrical gear, the first cylindrical gear and the worm gear 6 are sleeved on the same rotating shaft, the second cylindrical gear is arranged in meshing with the first cylindrical gear, and the second cylindrical gear is sleeved on the outer screw rod 22.

[0062] It should be noted that by adding the gear transmission assembly 7 and the worm gear 6, worm, etc. transmission structure between the support rod 2 and the driving device 5, the support rod 2 and the driving device 5 can be separated, and the support rod 2 is made into a screw transmission structure, so as to compress the necessary meshing height, compress the height of the entire electric waist bridge structure to the height that can be put into the bed body support 4, so as to be hidden in the bed body support 4 as a whole, so as to realize the overall concealment effect when the waist bridge plate 1 is retracted, thereby avoiding affecting the translation or mutual influence when used with other equipment.

[0063] In addition, it should be noted that the matching transmission of the worm gear and the cylindrical gear has a self-locking function, wherein the worm gear is one-way transmission, and only the worm can drive the worm gear 6 (the motor of the driving device 5 is connected with the worm, and the worm can drive the worm gear 6 to rotate), and the worm cannot drive the worm gear, and the meshing relationship of the first cylindrical gear and the second cylindrical gear is also one-way transmission, rather than bidirectional transmission, which can make the lifting movement of the waist bridge plate 1 have a reverse self-locking function, that is, when the waist bridge plate 1 moves to a certain position, even if the waist bridge plate 1 carries an object, it will not easily fall down, causing a dangerous accident.

[0064] In an embodiment, the diameter of the first cylindrical gear is smaller than the diameter of the second cylindrical gear.

[0065] In an embodiment, the gear transmission assembly 7 includes a first bevel gear and a second bevel gear, the first bevel gear and the worm gear 6 are sleeved on the same rotating shaft, the second bevel gear is in meshing arrangement with the first bevel gear, the second bevel gear is sleeved on the outer screw rod 22, and the driving device 5 includes a waist bridge motor with a brake or a worm gear and worm type speed reducer motor.

[0066] It should be noted that the worm gear and the cylindrical gear are replaced by a bevel gear, which can also separate the support rod 2 and the driving device 5 (waist bridge motor part) and transmit power and change the direction of motion, so as to realize the compression of the overall size and achieve the purpose of hiding. However, the bevel gear does not have a self-locking function, and a waist bridge motor with a brake or a worm gear and worm type speed reducer motor needs to be selected to avoid the dangerous phenomenon that the waist bridge plate 1 will fall down after carrying a certain weight.

[0067] In an embodiment, the driving device 5 is provided with an encoder to ensure that the two waist bridge plates 1 are synchronously lifted by a control program algorithm.

[0068] It should be noted that in use, firstly the worm is driven to rotate by the driving device 5, the rotation of the worm can drive the worm gear 6 to rotate, so as to convert the horizontal rotation of the driving device 5 into the rotation in the vertical direction, and then the motion is transmitted to the outer screw rod 22 through the gear transmission assembly 7, and the rotation of the outer screw rod 22 drives the inner screw rod 21 to ascend or descend. This structure can utilize the reverse self-locking function of the worm gear to prevent the waist bridge plate 1 from automatically descending after being stressed. Moreover, the structures on both sides of the waist bridge plate 1 are completely consistent, the driving device 5 is provided with an encoder, and the synchronous ascending or descending of the waist bridge plate 1 on both sides is ensured through a control program algorithm, so that the waist bridge plate 1 is prevented from tilting due to uneven stress.

[0069] In an embodiment, the support rod further comprises an intermediate screw rod, the intermediate screw rod is sleeved on the outer circumferential part of the inner screw rod 21, the outer screw rod 22 is sleeved on the outer circumferential part of the intermediate screw rod, and the intermediate screw rod, the inner screw rod 21, the outer screw rod 22 and the intermediate screw rod are all in threaded connection. That is, for the case that the waist bridge stroke is large, the primary screw rod transmission (only comprising the inner screw rod 21 and the outer screw rod 22) cannot guarantee that the device can be hidden into the bed body support 4 as a whole, at this time, two-stage screw rod transmission can be adopted, that is, an intermediate screw rod structure is added (the outer screw rod 22 and the intermediate screw rod are a screw rod transmission structure, and the intermediate screw rod and the inner screw rod 21 are a screw rod transmission structure).

[0070] It should be further noted that the outer screw rod 22 and the intermediate screw rod are in threaded connection, the intermediate screw rod and the inner screw rod 21 are in threaded connection, when the outer screw rod 22 rotates, the intermediate screw rod can be driven to move upwards (at this time, the intermediate screw rod and the inner screw rod 21 do not move relatively), when the intermediate screw rod is moved to the position, the intermediate screw rod does not move upwards any more, if the outer screw rod 22 continues to rotate, the intermediate screw rod will be driven to rotate together, at this time, the rotation of the intermediate screw rod drives the inner screw rod 21 to move upwards until the inner screw rod 21 moves to the position, so that the support rod 2 and the waist bridge plate 1 are raised to the maximum position.

[0071] In an embodiment, a fixing frame 8 is further included, the driving device 5, the worm, the worm gear 6 and the gear transmission assembly 7 are all arranged in the fixing frame 8, and the inner screw rod 21 passes through the fixing frame 8 and the bed body support 4 and is connected with the waist bridge plate 1. That is, all transmission parts on each side can be integrated together through the fixing frame 8, for example, all transmission parts and the fixing frame 8 can be prefabricated in advance, and then the fixing frame 8 is installed into the bed body support 4 to be fixed.

[0072] In addition to the hidden waist bridge structure for a surgical bed described above, the utility model also provides a surgical bed comprising the hidden waist bridge structure for a surgical bed disclosed in the above embodiment, and the structures of other parts of the surgical bed refer to the prior art, which will not be described herein.

[0073] It needs to be explained that the first cylindrical gear and the second cylindrical gear, the first bevel gear and the second bevel gear mentioned in the application file, wherein the first and the second are only to distinguish the different positions, and there is no difference between the first and the second.

[0074] In addition, it also needs to be explained that the "up and down", "horizontal", "vertical" and the like indicated by the application are based on the orientation or position relationship shown in the drawings, and are only for the convenience of simplifying the description and facilitating understanding, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.
