[0031] The embodiment of the present application provides a medical accessory connection device for connecting a support member 200 to an operating table.

[0032] An embodiment of the present application provides an operating bed, which includes an operating bed body 300, a support member 200, and a medical accessory connection device of any embodiment of the present application.

[0033] The support member 200 is used to support a part of the medical object. Exemplarily, the support member 200 is used to support the arm of the medical object. The specific structure of the support member 200 is not limited. In the embodiment of the present application, the support member is a rectangular support plate as an example for description, and the support member 200 has a support surface 200a, and the support surface 200a is used to contact with the medical object and provide support to the medical object.

[0034] The operating table body 300 and the support member 200 are connected via a medical accessory connection device.

[0035] For example, see Figure 4 The operating bed body 300 includes a table top 31 and a column 32 , and the table top 31 is arranged on the top of the column 32 .

[0036] Exemplarily, the table 31 includes a seat plate and a back plate, wherein the back plate is connected to the head end side of the seat plate. The back plate can be folded relative to the seat plate so that the medical subject can sit on the seat plate and lean against the back plate.

[0037] For example, see Figure 5 The bottom of the table top 31 on opposite sides along the width direction has a bed beam 312, and the bed beam 312 extends along the length direction of the table top 31, that is, roughly extends in the direction from the head end side to the foot end side of the table top 31, or extends in the direction from the foot end side to the head end side.

[0038] See also Figure 1 The medical accessory connecting device includes a base 14, a first ball joint 12A and a connecting assembly.

[0039] The base 14 has a first end and a second end. The first end of the base 14 is directly or indirectly connected to the operating bed body 300, and the second end is lower than the bottom of the table top 31 of the operating bed. It is understandable that the first end of the base 14 can be directly connected to the operating bed body 300, or indirectly connected to the operating bed body 300 through other structures, for example, indirectly connected to the operating bed body 300 through the slide rail 15 and adapter plate 16 described below. The second end of the base 14 is lower than the bottom of the table top of the operating bed, which means that the second end of the base 14 is lower than the corresponding part of the bottom of the table top 31 of the operating bed to which it is connected, preferably, lower than the part of the table top 31 of the operating bed corresponding to the connecting component in the height direction of the operating bed when the connecting component is in the supporting state.

[0040] It should be noted that the bottom of the table top refers to the bottom of the table top 31 in a plate-like structure, for example, it can be the bottom surface of the seat board.

[0041] The first ball joint 12A is connected to the second end of the base 14. That is, the height of the first ball joint 12A is lower than the height of the first end of the base 14.

[0042] The connecting assembly is used to connect the first ball joint 12A and the supporting member 200 .

[0043] Among them, see Figure 1 The connection assembly includes at least one rod body (eg, the first rod body 11 described below), and at least one second ball joint 12B.

[0044] The connecting assembly moves relative to the base 14 via the first ball joint 12A, so that the connecting assembly has a storage state and a support state. It should be noted that in some embodiments, the connecting assembly only moves relative to the base 14 via the first ball joint 12A, so that the connecting assembly switches between the storage state and the support state; in other embodiments, the connecting assembly moves relative to the base 14 via the first ball joint 12A, and the connecting assembly switches between the storage state and the support state via the relative movement of the second ball joint 12B of the connecting assembly.

[0045] In the storage state, the connection assembly drives the support member 200 to move to the bottom of the table 31 .

[0046] In the supporting state, a part of the connecting assembly and the supporting member 200 extend from below the table 31, so that the supporting member 200 can support a part of the medical object. The supporting state can be any state that can support a part of the medical object, and the supporting position and angle of the supporting member 200 may change in different body positions of the medical object.

[0047] In the embodiment of the present application, when the support member 200 is not needed, the connection assembly and the support member 200 can be stored under the table 31. At this time, the support member 200 and the connection assembly will basically not interfere with the operation of medical staff, will not affect the bed, and will not need to disassemble the medical accessory connection device, and will not need to find a separate storage location for the medical accessory connection device, which is convenient for storage. When the support member 200 is needed, the connection assembly and the support member 200 are extended from under the table, and the support member 200 is adjusted to the desired position, which is convenient for operation.

[0048] Exemplarily, the connection assembly and the support member 200 are connected via the second ball joint 12B, so that the support member 200 can swing universally relative to the connection assembly. In this way, even if the overall position of the connection assembly remains unchanged, the support member 200 can achieve universal adjustment of the angle of the support member 200 through the swing of the second ball joint 12B, that is, the approximate position of the support member 200 in space remains unchanged, and only the angle is adjusted. Of course, when the position of the connection assembly changes, the support member 200 can still achieve universal adjustment of the angle of the support member 200 through the swing of the second ball joint 12B.

[0049] It should be noted that the direction in which the connecting component drives the support member 200 to extend from the bottom of the table top 31 is not limited. For example, it can extend from one side of the table top 31 along the width direction, or from one side of the table top 31 along the length direction.

[0050] For example, see Figure 1 and Figure 5 The medical accessory connection device includes a slide rail 15 connected to the operating table, and the base 14 is slidably connected to the slide rail 15. In this embodiment, when the base 14 slides on the slide rail 15, it can drive the connection assembly and the support member 200 to move together, which can be applicable to the support requirements on any side of the operating table along the extension direction of the slide rail 15. The base 14 can drive the connection assembly support member 200 to slide to the side where the support requirements are.

[0051] Exemplarily, the slide rail 15 extends along the width direction of the operating bed body 300, so that when the base 14 slides on the slide rail 15, the base 14 drives the connection assembly and the support member 200 to move along the width direction of the table top 31, so that the connection assembly can drive the support member 200 to extend from below the table top 31 and toward any side of the width direction of the table top 31. In this embodiment, the two sides along the width direction of the table top 31 can share the same support member 200 and the connection device. For example, when the medical subject lies on the first side in the width direction, the support member 200 can extend from the first side in the width direction below the table top 31 to support the arm of the medical subject; when the medical subject lies on the other side in the width direction, the support member 200 can extend from the second side in the width direction below the table top 31 to support the arm of the medical subject.

[0052] The specific connection position of the table top 31 for connecting the slide rail 15 is not limited, and any appropriate structure can be used.

[0053] Exemplarily, the two ends of the slide rail 15 are respectively connected to the corresponding bed beams 312, that is, the slide rail 15 is connected between the two bed beams 312. In this way, the space between the two bed beams 312 can be fully utilized, and it is also convenient to maintain a spacing distance between the slide rail 15 and the bottom surface of the table 31 to prevent interference. In this embodiment, the base 14 slides on the slide rail 15, driving the connecting assembly and the support member 200 to move along the width direction of the table 31, so that the connecting assembly can drive the support member 200 to extend from below the table 31 and toward any side of the width direction of the table 31. In this embodiment, the two sides along the width direction of the table 31 can share the same support member 200 and medical accessory connection device. It should be noted that in this embodiment, the extension direction of the slide rail 15 can be completely parallel to the width direction of the table 31, or it can be at a certain angle, that is, in the projection of the horizontal plane, the slide rail 15 extends obliquely relative to the width direction of the operating bed body 31.

[0054] For example, see Figure 1 The medical accessory connection device also includes an adapter plate 16, and at least two ends of the slide rail 15 are connected to the bottom of the table 31 through the adapter plate 16. In this way, it is convenient to set a connecting structure on the adapter plate 16, which is convenient for connection and can also enable both ends of the slide rail 15 to be well supported.

[0055] The specific structure of the adapter plate 16 is not limited.

[0056] Exemplarily, the board surface of the adapter plate 16 and the extension direction of the slide rail 15 are perpendicular to each other, and a connection hole is provided on the adapter plate 16 so that the fastener can pass through the connection hole and connect to the table 31. In some specific implementations, the adapter plate 16 is stacked on the side of the two bed beams 312 facing each other, and the two adapter plates 16 are arranged face to face, so that the adapter plate 16 and the bed beam 312 can have a larger contact area, thereby improving the connection reliability between the two.

[0057] For example, see Figure 2 and Figure 3 , the first ball joint 12A and the second ball joint 12B respectively include: a ball 122, a seat 121 and an adjusting member 123. That is to say, the first ball joint 12A and the second ball joint 12B can adopt similar or identical structures. For the first ball joint 12A, the first ball joint 12A includes the ball 122, the seat 121 and the adjusting member 123. For the second ball joint 12B, the second ball joint 12B includes: a ball 122, a seat 121 and an adjusting member 123.

[0058] The seat body 121 is provided with a ball head accommodating portion and an inserting hole 121 a , the ball body 122 is arranged in the ball head accommodating portion, and the inserting hole 121 a is used for inserting with the rod body.

[0059] The adjusting member 123 has a locking position and a releasing position. The adjusting member 123 switches between the locking position and the releasing position under the operation of medical personnel.

[0060] When in the locking position, the adjusting member 123 locks the rod body and the ball body 122 on the seat body 121; at this time, the rod body, the ball body 122 and the seat body 121 remain relatively still, and there is no relative movement between the three.

[0061] In the release position, the ball 122 and the ball head receiving portion can rotate relative to each other, and the rod body can move in the insertion hole 121a, including rotation and linear movement.

[0062] It should be noted that the insertion hole 121 a and the ball head receiving portion will not interfere with each other, the insertion hole 121 a will not pass through the ball head receiving portion, and the rod body will not be inserted into the ball head receiving portion.

[0063] The medical accessory connecting device of the embodiment of the present application, for the same ball joint (for example, the first ball joint 12A, or the second ball joint 12B), only needs to operate the same adjustment member 123 to simultaneously lock the rod body and the ball joint, or simultaneously release the rod body and the ball joint, that is, one adjustment member 123 locks the two components, which is easy to operate and improves the operating convenience of medical staff.

[0064] Exemplarily, the plug hole 121a penetrates the outer surface of the two opposite sides of the seat body 121, and the rod body passes through the plug hole 121a, that is, the rod body enters from one end of the plug hole 121a and exits from the other end. When the adjustment member 123 is in the release position, the rod body can slide in the plug hole 121a along the extension direction of the plug hole 121a through the seat body 121. In this way, the translation of the rod body can be achieved, so that the rod body and the support member 200 can obtain a larger position condition range.

[0065] For some examples, see Figure 2 and Figure 3 The seat body 121 includes a sleeve 1211 , an end cover 1212 , and a pressing block 1213 . One end of the sleeve 1211 has a first opening, and the other end has a second opening. The pressing block 1213 is disposed in the sleeve 1211 .

[0066] The pressing block 1213 has a pressing surface on one side facing the first opening, and the pressing surface and a part of the inner surface of the sleeve 1211 define a ball head receiving portion, in which the ball 122 is disposed. It should be noted that the size of the first opening is smaller than the diameter of the ball 122, and the ball 122 will not fall out of the first opening.

[0067] The pressing surface of the pressing block 1213 can be a conical surface, or a part of a spherical surface, or an inclined surface, as long as it presses the sphere 122 tightly.

[0068] The plug hole 121a passes through opposite sides of the circumferential surface of the sleeve 1211. The extension direction of the rod inserted in the plug hole 121a is substantially perpendicular to the axis of the sleeve 1211. The plug hole 121a can pass through the pressing block 1213, that is, the rod inserted in the plug hole 121a can also pass through the pressing block 1213.

[0069] The diameter of the plug hole 121a is larger than the corresponding rod diameter; alternatively, the plug hole 121a may be elliptical, waist-shaped, etc. Along the axial direction of the sleeve 1211, the size of the plug hole 121a is larger than the corresponding rod diameter, so that the rod can move in the plug hole 121a along the axial direction of the sleeve 1211 under the action of external force.

[0070] The end cover 1212 is disposed at the second opening and covers the second opening. One end of the adjusting member 123 passes through the end cover 1212 and abuts against the rod body, so that the rod body pushes the pressing block 1213 , and the pressing block 1213 locks the ball 122 .

[0071] In other alternative embodiments of the present specification, one end of the adjusting member 123 passes through the end cover 1212 and abuts against the pressing block 1213 to lock the ball 122 and the rod body through the pressing block 1213 .

[0072] In this embodiment, the direction in which the adjusting member 123 applies force to the rod is substantially parallel to or coincides with the axis of the sleeve 1211, and the insertion direction of the rod is substantially perpendicular to the axis of the sleeve 1211. Therefore, the rod is not likely to interfere with the operator's operation of the adjusting member 123, which is convenient for the operator to operate. In addition, it is also convenient for the rod to slide along the extension direction of the plug hole 121a penetrating the sleeve 1211. It should be noted that the extension direction of the plug hole 121a penetrating the sleeve 1211 is the extension direction of the plug hole 121a penetrating the seat body 121.

[0073] In other embodiments, the seat body 121 further includes an elastic damping member, which is disposed between the end cover 1212 and the pressing block 1213 to apply a force to the pressing block 1213. For example, when the adjustment member 123 is in the release position, the elastic damping member applies a force to the pressing block 1213, so that the pressing block 1213 generates a pre-tightening force on the ball 122, so that even if the adjustment member 123 is in the release position, when the operator does not apply a force to the ball 122, the ball 122 will not shake freely in the ball head accommodating portion.

[0074] It should be noted that, in some other embodiments, the elastic damping member mentioned above may also be eliminated.

[0075] The specific structure of the adjusting member 123 is not limited. For example, please refer to Figure 2 and Figure 3 The adjusting member 123 includes a handle 1231 and a threaded rod 1232 connected to each other. The handle 1231 is located on the outer surface of the end cover 1212. The threaded rod 1232 passes through the end cover 1212 and abuts against the corresponding rod body. By screwing the handle 1231, the force of the threaded rod 1232 on the rod body can be adjusted.

[0076] Exemplarily, the base 14 is connected to the ball 122 of the first ball joint 12A, that is, there is no relative movement between the ball 122 of the first ball joint 12A and the base 14. The angle between the axis of the first ball joint 12A and the extension direction of the slide rail 15 is 30° to 90°, for example, 30°, 45°, 55°, 60°, 75°, 90°, etc. It should be noted that the angle has no directionality and can be understood as an angle of no more than 90° formed by two intersecting straight lines in a plane.

[0077] The axis of the first ball joint 12A is a straight line passing through the center of the sphere 122 and perpendicular to the plane where the sphere 122 and the base 14 intersect.

[0078] In this embodiment, the range of the angle can reduce the probability of interference between the seat body 121 of the first ball joint 12A and the slide rail 15 when the seat body 121 swings universally relative to the ball body 122 .

[0079] See also Figure 2 and Figure 3 In some embodiments, the medical accessory connection device further includes a gripping tube 13, and a ball 122 of a second ball joint 12B connected to the support member 200 is connected to the gripping tube 13, and then connected to the support member 200 through the gripping tube 13. The center of the ball 122 of the second ball joint 12B is located on the axis of the gripping tube 13, and the outer diameter of the gripping tube 13 is greater than or equal to the outer diameter of the ball 122. The gripping tube 13 is convenient for medical personnel to hold, can improve clinical operation comfort, and is also convenient for the connection between the second ball joint 12B and the support member 200.

[0080] Of course, in other embodiments, the above-mentioned holding tube 13 may not be disposed between the ball 122 of the second ball joint 12B and the support member 200 .

[0081] The number of rods of the connecting assembly is not limited, and may be one, two, or more than two.

[0082] For example, in some embodiments, please refer to Figure 1 , at least one rod body includes a first rod body 11 , that is, one of the rod bodies of the connecting assembly is the first rod body 11 .

[0083] The first rod body 11 includes a first rod segment 111 and a second rod segment 112. The first rod segment 111 is inserted into the insertion hole 121a of the first ball joint 12A. The second rod segment 112 extends from the second end of the first rod segment 111 toward the side of the first rod segment 111. The first rod body 11 is not a straight rod, but a bent rod, for example, roughly "L"-shaped.

[0084] The second rod section 112 is inserted into the plug hole 121a of the second ball joint 12B connected to the support member 200. That is, in this embodiment, there is only one rod body, namely the first rod body 11. The curved structure of the first rod body 11 facilitates avoiding the edge of the table 31, so that the support member 200 can extend from the bottom of the table 31 while also being able to change its displacement in the upward height direction, so as to facilitate supporting the arm and other parts of the medical subject.

[0085] In some other embodiments, the connection assembly includes at least two rods connected in sequence, and two adjacent rods are connected through a second ball joint 12B. Among them, the first rod located in the sequential connection direction is the first rod 11, and the first rod 11 is inserted into the insertion hole 121a of the first ball joint 12A, and the last rod located in the sequential connection direction is the second rod, and the second rod is inserted into the insertion hole 121a of the second ball joint 12B connected to the support member 200. In this embodiment, the number of rods is at least two, and through the mutual rotation and / or sliding between the multiple rods, the support member 200 can have a larger adjustment range in the horizontal direction and the height direction.

[0086] Of course, in other embodiments, the connection assembly may include three or more rods connected in sequence.

[0087] For example, see Figure 1 The base 14 includes a connecting portion 141 at a first end and an extending portion 142 extending downward or obliquely downward from the connecting portion 141. Specifically, the base 14 is slidably connected to the slide rail 15 through the connecting portion 141, and the base 14 is connected to the ball 122 of the first ball joint 12A through the extending portion 142.

[0088] In this embodiment, since the extension portion 142 extends downward, the connection position between the connection component and the base 14 is relatively low, which facilitates the connection component to extend from under the table 31 and reduces the probability of interference between the connection component, the support member 200 and the table 31.

[0089] The specific structure of the connection portion 141 is not limited.

[0090] Exemplarily, the connection part 141 has a slot and a locking member, the slide rail 15 is inserted into the slot, and the locking member passes through the side wall of the slot and abuts against the slide rail 15, so that the connection part 141 can be locked on the slide rail 15 to prevent the connection part 141 from sliding freely on the slide rail 15. When the connection part 141 needs to slide, the locking member is loosened, and after the connection part 141 is slid to the desired position, the locking member is tightened again to lock the connection lock on the slide rail 15. In this embodiment, the support reliability of the medical accessory connection device and the support member 200 can be improved.

[0091] The shape of the extension portion 142 is not limited. For example, see Figure 1 , the shape of the extension portion 142 can be rod-shaped.

[0092] The cross-sectional shape of the slide rail 15 may be circular or non-circular.

[0093] Exemplarily, in the storage state, any part of the medical accessory connection device does not extend out of any side of the table 31 in the horizontal direction. Specifically, in the horizontal plane projection, the projection of the medical accessory connection device and the support member 200 is located within the projection range of the table 31. In this way, the medical accessory connection device and the support member 200 will not interfere with medical personnel and will not affect the placement of peripheral equipment of the operating table.

[0094] Exemplarily, the distance between the base 14 and the end of the first end of the table 31 is less than the length of the rod of the connection assembly in the supporting state, so that the connection assembly can drive the support member 200 to extend from below the table 31 and toward the side of the first end in the length direction of the table 31. It should be noted that the length of the rod of the connection assembly in the supporting state refers to the projection length of the entire connection assembly in the horizontal plane when the support member 200 moves to a posture that can support a part of the medical patient.

[0095] In this embodiment, even if the slide rail 15 is not configured, the support member 200 can extend from one side of the first end of the table top 31 in the length direction, so as to support the arm of the medical subject when the medical patient is in a side-lying position and the arm extends beyond the table top 31 in the length direction.

[0096] For example, the base 14 is positioned downwardly beyond the lowest position of the preset position of the bed beam 312, wherein the preset position is: the position of the bed beam 312 corresponding to the connecting component in the height direction of the operating bed when the connecting component is in the supporting state. In this way, even if there is only one rod of the connecting component, it can avoid the bed beam 312, so as to facilitate the extension of the connecting component and the support member 200.

[0097] It should be noted that the part of the bed beam 312 corresponding to the connecting component in the height direction of the operating bed when the connecting component is in the supporting state means that when the connecting component is in any supporting state, the connecting component has a projection area in the length direction of the bed beam, and the part of the bed beam within the length range of the projection area is the above-mentioned preset part.

[0098] A specific embodiment of the above embodiments is briefly introduced below with reference to the accompanying drawings.

[0099] See also Figures 1 to 5 The rod assembly of the medical accessory connecting device has one rod, which is a first rod 11. The first rod 11 includes a first rod segment 111 and a second rod segment 112 that are perpendicular to each other. The length of the first rod segment 111 may be greater than the length of the second rod segment 112.

[0100] The overall structures of the first ball joint 12A and the second ball joint 12B are substantially the same, except that the ball 122 of the second ball joint 12B is connected to the gripping tube 13 , while the ball 122 of the first ball joint 12A is not connected to the gripping tube 13 .

[0101] The ball joint includes a ball body 122 , a seat body 121 and an adjusting member 123 .

[0102] The seat body 121 includes a sleeve 1211, an end cover 1212, and a pressing block 1213. The sleeve 1211 has a first opening at one end and a second opening at the other end. The pressing block 1213 is disposed in the sleeve 1211. The side of the pressing block 1213 facing the first opening and a part of the side wall of the sleeve 1211 define a ball head accommodating portion. A part of the ball 122 is accommodated in the ball head accommodating portion. The plug hole 121a passes through the opposite sides of the sleeve 1211 along the circumferential surface and passes through the pressing block 1213. The end cover 1212 is disposed at the second opening. One end of the adjusting member 123 passes through the end cover 1212 and directly abuts against the rod body.

[0103] The first rod body 11 includes a first rod segment 111 and a second rod segment 112 which are perpendicular to each other. The first rod segment 111 is inserted into the insertion hole 121a of the first ball joint 12A, and the second rod segment 112 is inserted into the insertion hole 121a of the second ball joint 12B. The ball 122 of the second ball joint 12B is used to connect the support member 200.

[0104] The connecting portion 141 is in a square sleeve shape and has the above-mentioned slot.

[0105] Both ends of the slide rail 15 are connected to the corresponding bed beams 312 through the adapter plate 16 .

[0106] The above specific embodiment can realize at least the following three supporting postures: Herein, the supporting member 200 is described as a rectangular supporting plate as an example.

[0107] The first support posture

[0108] See also Figure 6 The support member 200 is located at one side of the operating bed body 300 along the width direction, the support surface 200a of the support member 200 faces upward, the length direction of the support member 200 is parallel to the width direction of the operating bed body 300, and the support surface 200a of the support member 200 is roughly flush with the upper surface of the table 31 (it can be slightly higher or lower). The support member 200 is roughly located at the position of the medical patient's arm, and this support posture can support an arm of the medical subject who is in a lateral position and close to the table 31.

[0109] Second support posture

[0110] See also Figure 7The support member 200 is located at the head end side of the operating bed body 300 along the length direction, and the support surface 200a of the support member 200 faces upward, and its height is lower than the upper surface of the table 31, for example, it can also be lower than the lower surface of the table 32, and even lower than the bed beam 312. The length direction of the support member 200 is roughly parallel to the width direction of the operating bed body 300. This supporting posture can realize the support of the arm of the medical subject in another side-lying posture. In this side-lying posture, the head of the medical subject is higher than the table 31, and the arm exceeds the operating bed body 300 from the head end side and is bent to be placed on the support member 200.

[0111] The third support posture

[0112] See also Figure 8 The support member 200 is located on one side of the operating bed body 300 along the width direction, and the support surface 200a of the support member 200 faces obliquely upward to the head end side of the operating bed body 300, that is, along the length direction of the support member 200, the height close to the head end side of the operating bed body 300 is lower than the height at the other end. This support posture can be suitable for supporting the arms of a medical subject in a prone position.

[0113] It should be noted that the above-mentioned first supporting posture and the third supporting posture are only introduced by taking the example that the supporting member 200 extends from one side in the width direction of the operating bed body 300. It can be understood that when the base 14 slides relative to the slide rail 15 to the other end of the slide rail 15, the supporting member 200 can extend from the other side of the operating bed body 300.
