[0012] The first ball joint comprises a ball, a seat and an adjusting member, wherein the adjusting member has a locking position and a releasing position, wherein the adjusting member locks the second rod and the ball on the seat in the locking position; and wherein the ball and the seat can rotate relative to each other and the second rod can move relative to the seat in the releasing position.

[0013] The first rod body includes a rod portion and a bend portion, the bend portion is connected to the rod portion and extends laterally to the rod portion, and the ball of the first ball joint is fixed to the bend portion.

[0042] The embodiment of the present application provides a medical support member connecting device for connecting a medical device body and a support member. That is, the support member is attached to the medical device body through the medical support member connecting device.

[0043] There is no limit to the type of medical equipment body, for example, including but not limited to: operating table, medical tower bridge, etc.

[0044] In the embodiments of the present application, description is made by taking the medical device main body as an operating table as an example.

[0045] The specific type of the support member is not limited. The embodiment of the present application is described by taking the support member as the support plate 200 as an example, and it is understandable that the support member can also be of other types.

[0046] The medical support member connecting device comprises a rod assembly and at least two ball joints 12 .

[0047] The rod assembly includes at least two rods connected in sequence. The sequential connection means that the rods are connected in sequence. For example, if there are three rods, the first rod, the second rod, and the third rod are connected in sequence, that is, the first rod is connected to the second rod, and the second rod is connected to the first rod and the third rod, to form a type of mechanical arm structure.

[0048] See also Figure 4 The ball joint 12 includes a ball body 122, a seat body 121 and an adjusting member 123. 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 staff.

[0049] 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.

[0050] In the release position, the ball 122 and the seat 121 can rotate relative to each other, and the rod can move relative to the seat 121, wherein the movement of the rod includes rotation and / or linear motion.

[0051] Adjacent rods are connected via the ball joint 12. Specifically, of two adjacent rods, one is connected to the ball 122 of the ball joint 12, and the other is connected to the seat 121 of the ball joint 12. When the ball head and the seat 121 swing relative to each other, and / or the rod rotates and / or moves linearly relative to the seat 121, relative movement between the two adjacent rods can be achieved, and the spatial relative positions of the two adjacent rods can be adjusted.

[0052] For ease of description, see Figure 1, a rod at the head end in the sequential direction is referred to as the first rod 11A, and the ball joint 12 connected to the first rod 11A is referred to as the first ball joint 12A. The second rod at the sequential direction is referred to as the second rod 11B, and another ball joint 12 connected to the second rod 11B is referred to as the second ball joint 12B. The rod at the end in the sequential direction is referred to as the terminal rod, and a ball joint 12 connected to the end of the terminal rod is referred to as the terminal ball joint.

[0053] It should be noted that the number of rod bodies may be two, or more than two.

[0054] In the embodiment where the number of rods is two, the second rod 11B is the end rod, and the second ball joint 12B is the end ball joint. In the embodiment where the number of rods is more than two, the second rod 11B and the end rod are not the same rod, and the second ball joint 12B and the end ball joint are not the same ball joint 12.

[0055] See also Figure 1 The first rod body 11A includes a rod portion 111 and a bend portion 112. The rod portion 111 extends substantially in a straight line. In other embodiments, the rod portion 111 may also be bent according to the application. The bend portion 112 is connected to the rod portion 111 and extends laterally to the rod portion 111. The ball 122 of the first ball joint 12A is fixed to the bend portion 112.

[0056] In the medical support member connection device of the embodiment of the present application, when the seat body 121 of the first ball joint 12A drives the second rod body 11B to swing around the ball body 122 of the first ball joint 12A in all directions, the second rod body 11B can obtain a larger position adjustment range along the length direction of the first rod body 11A. The support member has a larger position adjustment amplitude and angle adjustment range, and can be suitable for clinical use scenarios of multi-position angle adjustment to meet the support needs of patients with different body positions and different body shapes.

[0057] For example, the rod 111 is arranged along the height direction of the medical equipment body, that is, the up and down direction. Then, when the seat 121 of the first ball joint 12A drives the second rod 11B to swing around the ball 122 of the first ball joint 12A, the second rod 11B swings along with the seat 121, which can drive the support member to move away from or close to the operating bed body, or adjust roughly along the length direction of the operating bed body to adapt to the medical object, or move obliquely relative to the operating bed body to change the distance between the support member and the medical object. Through the rotation of the second rod 11B relative to the first ball joint 12A, the support member can have a larger position adjustment range in the horizontal plane. In addition, through the swing of the end ball joint on the end rod body, the support member can also have a larger angle adjustment range.

[0058] The medical support member connecting device of the embodiment of the present application, for the same ball joint 12, only needs to operate the same adjustment member 123 to simultaneously lock the rod body and the ball joint 12, or simultaneously release the rod body and the ball joint 12, that is, one adjustment member 123 locks the two components, which is easy to operate and improves the operating convenience of medical staff.

[0059] For example, see Figure 3 The axis L2 of the first ball joint 12A forms an angle θ with the center line L1 of the rod 111 , that is, the axis L2 of the first ball joint 12A and the center line L1 of the rod 111 are neither coincident nor parallel.

[0060] Among them, see Figure 3 The axis L2 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 intersects the turning portion 122 .

[0061] The angle θ can be measured by: in a reference plane determined by the intersection of the axis L2 of the first ball joint 12A and the center line L1 of the rod 111, starting from the intersection point, pointing from the intersection point to the direction of the sphere, and pointing to the direction of the rod 111 close to the connection part with the main body of the medical device, to form an angle. It should be noted that if the axis of the first ball joint 12A and the center line of the rod 111 are skew lines in space, the axis of the first ball joint 12A and the center line of the rod 111 are abstractly translated to the intersection of the two; if the axis of the first ball joint 12A and the center line of the rod 111 are in the same plane, the plane where the two are located is the above-mentioned reference plane.

[0062] Exemplarily, the seat body 121 of the ball joint 12 is provided with a ball head receiving portion and an inserting hole 121 a , the corresponding ball 122 is provided in the ball head receiving portion, and the inserting hole 121 a is used for inserting with the rod body.

[0063] 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.

[0064] For example, see Figure 4 and Figure 5 The plug hole 121a penetrates the outer surfaces of the two opposite sides of the seat body 121, and the rod body penetrates from one end of the plug hole 121a and passes out 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 penetrating the seat body 121 (i.e., linear motion) and / or the rod body can rotate relative to the plug hole 121a. In this way, the translation and rotation of the rod body can be realized, and a larger movement stroke can be obtained.

[0065] The diameter of the plug hole 121a is larger than the corresponding rod body diameter; alternatively, the plug hole 121a may be elliptical, waist-shaped, etc., and along the axial direction of the sleeve 1211, the size of the plug hole 121a is larger than the corresponding rod body diameter (that is, the size in the long axis direction of the ellipse is larger than the diameter of the rod body, and the size in the direction of the line connecting the centers of the two arcs of the waist-shaped one is larger than the diameter of the rod body), so that the rod body can move in the plug hole 121a along the axial direction of the sleeve 1211 under the action of external force.

[0066] For example, see Figure 2 The second rod 11B can move relative to the first ball joint 12A along the direction of arrow C1, and the support member can move relative to the second rod 11B along the direction C2 along with the second ball joint 12B.

[0067] Exemplarily, the end rod body is inserted into the socket hole 121a of the end ball joint, and the ball 122 of the end ball joint is used to connect the support member. In this way, when the position of the end rod body remains unchanged, the support member can achieve universal adjustment of the angle of the support member through the swing of the corresponding ball 122. That is to say, the approximate position of the support member in space remains unchanged, and only the angle is adjusted.

[0068] For some examples, see Figure 4 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 .

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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 .

[0073] 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 .

[0074] In this embodiment, the direction in which the adjusting member 123 applies force to the rod body is roughly parallel to or coincides with the axis of the sleeve 1211, and the insertion direction of the rod body is roughly perpendicular to the axis of the sleeve 1211. Therefore, the rod body is not likely to interfere with the operator's operation of the adjusting member 123, which facilitates the operator's operation. In addition, it is also convenient for the rod body to slide along the extension direction of the plug hole 121a through the sleeve 1211.

[0075] 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.

[0076] It should be noted that, in some other embodiments, the elastic damping member mentioned above may be eliminated.

[0077] The specific structure of the adjusting member 123 is not limited. For example, please refer to Figure 4 The adjusting member 123 includes a handle 1231 and a threaded rod 1232 which are connected to each other. The handle 1231 is located on the outside of the end cover 1212, and the threaded rod 1232 passes through the end cover 1212 and abuts against the corresponding rod body.

[0078] Exemplarily, the angle θ is not less than 40° and less than 180°, that is, 40°≤θ<180°. For example, 40°, 50°, 70°, 80°, 90°, 110°, 130°, 150°, 170°, etc. This angle makes the angle range between the rod 111 and the turning portion 112 reasonable, and the angle will not be too small, which reduces the processing difficulty and also reduces the probability of interference of the rod 111 with the seat body 121 when it swings.

[0079] In some embodiments, the first rod 11A and the ball 122 of the first ball joint 12A are an integrated structure, that is, the rod 111, the bend 112 and the ball 122 of the first ball joint 12A are an integrated structure. For example, a plastic part formed by integral injection molding, or an integrated metal part. The integrated structure can improve the structural strength of the connection between the bend 112 and the ball 122. In addition, even if the length of the bend 112 is short, the connection reliability between the ball 122 and the bend 112 can be guaranteed.

[0080] In some other embodiments, the first rod body 11A and the ball body 122 of the first ball joint 12A may also be independent components and connected together, for example, by screws, welding, etc.

[0081] The included angle β between the center line of the turning portion 112 and the center line of the rod portion 111 is not limited.

[0082] Exemplarily, the angle between the center line of the turning portion 112 and the center line of the rod 111 is 40° to 170°. For example, 40°, 55°, 73°, 86°, 90°, 100°, 110°, 130°, 150°, 170°, etc. The angle between the turning portion 112 and the rod 111 is not too small to reduce the difficulty of processing and the probability of interference of the rod 111 with the seat body 121 when it swings.

[0083] For example, the center line of the turning portion 112 is parallel to or coincides with the axis of the first ball joint 12A. In this way, the overall arrangement is relatively neat and beautiful.

[0084] In some other embodiments, the axis of the turning portion 112 and the axis of the first ball joint 12A may also intersect.

[0085] For example, see Figure 1 The second rod body 11B includes a first rod segment 113 and a second rod segment 114. The second rod segment 114 extends from one end of the first rod segment 113 toward the side of the first rod segment 113. That is, the second rod body 11B is not a straight rod, but a bent rod.

[0086] The first rod segment 113 is inserted into the insertion hole 121 a of the first ball joint 12A, and the second rod segment 114 is inserted into the insertion hole 121 a of the other ball joint 12 .

[0087] The structural form of the second rod body 11B facilitates the end of the second rod segment 114 to rotate around the center line of the first rod segment 113 to obtain a larger position adjustment range.

[0088] For example, see Figure 4 and Figure 5 The medical support member connection device further includes a gripping tube 13, a ball 122 of the terminal ball joint is connected to the gripping tube 13, and the terminal ball joint is connected to the support member through the gripping tube 13. The center of the ball 122 of the terminal ball joint 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 terminal ball joint. 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 terminal ball joint and the support member.

[0089] A specific embodiment of the present application is introduced below with reference to the accompanying drawings.

[0090] A medical support member connecting device is used to connect a medical device body and a support member, comprising a rod body component and two ball joints 12.

[0091] The rod assembly includes a first rod 11A and a second rod 11B. In this embodiment, there are two rods.

[0092] The two ball joints 12 are respectively a first ball joint 12A and a second ball joint 12B. The first rod 11A and the second rod 11B are connected via the first ball joint 12A, and the second rod 11B is connected to the support member via the second ball joint 12B.

[0093] The ball joint 12 includes a sphere 122, a seat body 121 and an adjusting member 123. The seat body 121 includes a sleeve 1211, an end cover 1212 and a clamping block 1213. One end of the sleeve 1211 has a first opening and the other end has a second opening. The clamping block 1213 is arranged in the sleeve 1211. The side of the clamping block 1213 facing the first opening and a part of the side wall of the sleeve 1211 define a ball head accommodating portion. At least a portion of the sphere 122 is accommodated in the ball head accommodating portion. The plug-in hole 121a passes through the opposite sides of the circumferential surface of the sleeve 1211. The end cover 1212 is arranged at the second opening. One end of the adjusting member 123 passes through the end cover 1212 and is supported on the corresponding rod body.

[0094] When the adjusting member 123 is pressed against the corresponding rod, the adjusting member 123 pushes the rod to push the pressing block 1213 , and the pressing block 1213 moves toward the direction close to the ball 122 , thereby locking the ball, thereby locking the ball 122 and the rod on the seat 121 .

[0095] When the adjusting member 123 releases the corresponding rod, the ball 122 can swing relative to the ball head receiving portion, and the rod inserted in the insertion hole 121a can rotate relative to the insertion hole 121a and slide along the direction of the insertion hole 121a passing through the sleeve 1211.

[0096] The first rod 11A includes a rod portion 111 and a bend portion 112. The bend portion 112 extends from one end of the rod portion 111 to the side of the rod portion 111. The first rod 11A is substantially L-shaped. For example, the extension length of the bend portion 112 may be less than the extension length of the rod portion 111.

[0097] The ball head of the first ball joint 12A is disposed at one end of the bend 112 away from the rod 111; the axis of the first ball joint 12A coincides with the center line of the bend 112. In an optional embodiment, the axis of the first ball joint 12A is perpendicular to the center line of the rod 111.

[0098] The second rod body 11B includes a first rod segment 113 and a second rod segment 114. The second rod body 11B is generally L-shaped, and the first rod segment 113 and the second rod segment 114 can be perpendicular to each other. The first rod segment 113 is inserted into the insertion hole 121a of the first ball joint 12A, and the second rod segment 114 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.

[0099] A specific embodiment of the above embodiments is briefly introduced below with reference to the accompanying drawings.

[0100] See also Figure 1 The rod assembly of the medical support member connecting device includes a first rod 11A and a second rod 11B.

[0101] The two ball joints 12 of the medical support member connecting device are respectively a first ball joint 12A and a second ball joint 12B. The first rod 11A and the second rod 11B are connected via the first ball joint 12A, and the second rod 11B is connected to the support member via the second ball joint 12B.

[0102] The ball joint 12 includes a sphere 122, a seat body 121 and an adjusting member 123. The seat body 121 includes a sleeve 1211, an end cover 1212 and a clamping block 1213. One end of the sleeve 1211 has a first opening and the other end has a second opening. The clamping block 1213 is arranged in the sleeve 1211. The side of the clamping block 1213 facing the first opening and a part of the side wall of the sleeve 1211 define a ball head accommodating portion. At least a portion of the sphere 122 is accommodated in the ball head accommodating portion. The plug-in hole 121a passes through the opposite sides of the circumferential surface of the sleeve 1211. The end cover 1212 is arranged at the second opening. One end of the adjusting member 123 passes through the end cover 1212 and can directly or indirectly abut on the rod body passing through the plug-in hole 121a.

[0103] When the adjusting member 123 is pressed against the rod body inserted into the insertion hole 121 a , the adjusting member 123 pushes the pressing block 1213 through the rod body to lock the ball head, thereby locking the ball head and the rod body on the seat body 121 .

[0104] When the adjusting member 123 releases the rod inserted in the insertion hole 121a, the ball head can swing relative to the ball head receiving portion, and the rod inserted in the insertion hole 121a can rotate relative to the insertion hole 121a and slide along the extension direction of the insertion hole 121a through the sleeve 1211.

[0105] The first rod body 11A includes a rod portion 111 and a bend portion 112. The bend portion 112 extends from an end of the rod portion 111 to a side of the rod portion 111. The ball head of the first ball joint 12A is disposed at an end of the bend portion 112 away from the rod portion 111. The axis of the first ball joint 12A coincides with the center line of the bend portion 112.

[0106] The second rod body 11B includes a first rod segment 113 and a second rod segment 114, which can be perpendicular to each other. The first rod segment 113 is inserted into the insertion hole 121a of the first ball joint 12A, and the second rod segment 114 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.

[0107] This application embodiment provides an operating table. Figures 6 to 13 , including an operating table main body 300, a support member, and a medical support member connecting device of any embodiment of the present application.

[0108] The support member is used to support a part of the medical object, and the operating table body 300 and the support member are connected via a medical support member connecting device.

[0109] The support member can provide auxiliary support to the local part of the medical object, so as to help keep the medical object in a desired position.

[0110] The specific structure of the support member is not limited. In the embodiment of the present application, a rectangular support plate 200 is used as an example for description.

[0111] When the adjusting member 123 is in the releasing position, the supporting posture of the supporting member can be adjusted through the relative rotation of the ball joint 12 and the seat body 121, and / or the movement of the rod body, wherein the movement includes rotation and / or linear motion. When the adjusting member 123 is in the locking position, the medical supporting member connecting device locks the supporting member in the current supporting posture.

[0112] The operating bed of the embodiment of the present application facilitates adjustment of the position and support posture of the support member through the medical support member connection device, thereby improving the user experience of medical personnel.

[0113] The location of the part of the operating bed body 300 that is connected to the medical support device is not limited and can be any suitable connection location, for example, connected to the side of the operating bed body 300, or the bottom side of the table top 31 of the operating bed body 300.

[0114] Exemplarily, the operating bed body includes a table top 31 and a column 32, and the table top 31 is arranged at the top of the column 32. Exemplarily, the table top includes a seat plate, a back plate, and a leg plate, the back plate is connected to the head end side of the seat plate, and the leg plate is connected to the foot end side of the seat plate. The back plate can rotate relative to the seat plate, so that the medical subject can sit on the seat plate and can lean on the back plate.

[0115] See also Figures 6 to 13, the medical support component connection device is connected to one side of the operating bed body 300. One side refers to one side of the operating bed body 300 along the periphery, for example, any side along the width direction, any side along the length direction, etc. For a single medical support component connection device, the single medical support component connection device is connected to one side of the operating bed body 300; in an embodiment where the number of medical support components connected is multiple, any side of the operating bed, or any multiple sides, can be connected to the medical support component connection device.

[0116] For example, in some embodiments, the number of medical support member connection devices is at least two, and the two opposite sides of the operating bed body 300 along the width direction are connected with medical support member connection devices. In this way, it is convenient to select a suitable support member for support according to the body position of the medical object, or to cooperate with the support members on the medical support member connection devices on both sides, so as to better support the medical object.

[0117] For example, see Figure 6 and Figure 7 The operating bed body 300 is connected to a first fixture 36 along the side of the width direction. Specifically, the first fixture 36 is arranged on the side of the table 31. The first fixture 36 has a socket and a first locking member 33. The first rod 11A is inserted into the socket. Specifically, the rod portion 111 of the first rod 11A is inserted into the socket. The first locking member 33 is used to lock the first rod 11A in the socket, or release the first rod 11A so that the first rod 11A rotates in the socket and / or moves along the extension direction of the socket.

[0118] In this embodiment, the installation and removal of the medical support member connection device can be facilitated.

[0119] Specifically, when the medical support connecting device needs to be connected, the first rod 11A is inserted into the socket and then locked with the first locking member 33. When the medical support connecting device needs to be disassembled, the first locking member 33 is released and the first rod 11A is pulled out of the socket.

[0120] In addition, in this embodiment, the movement of the first rod 11A in the socket facilitates the translation of the positions of the entire medical support member connecting device and the support member according to the movement of the first rod 11A.

[0121] For example, the socket extends in the up-down direction, and the first rod body 11A is inserted into the socket in the up-down direction. That is, the rod portion 111 of the first rod body 11A extends in the up-down direction. When the first rod body 11A moves up and down in the socket, the medical support member connecting device can drive the support member to move up and down, and the height of the support member can be quickly adjusted.

[0122] Of course, in other embodiments, the extension direction of the socket may also be at a certain angle to the up-down direction, for example, 10°, 20°, 30°, etc.

[0123] The specific structure of the first locking member 33 is not limited, for example, it can be a screw that passes through the first fixer 36 and is inserted into the socket. The end of the screw abuts against the surface of the first rod 11A, so that the first rod 11A can be locked in the socket.

[0124] For example, see Figure 6 and Figure 7 The operating bed body 300 is provided with a first slide rail 311 on the side along the width direction, and the first slide rail 311 extends along the length direction of the operating bed body 300. The first fixture 36 is connected to the first slide rail 311 and can slide relative to the first slide rail 311. When the first fixture 36 slides along the first slide rail 311, the first fixture 36 drives the medical support member connecting device and the support member to translate together, so that the support member can be moved to a desired position along the length direction of the operating bed body 300.

[0125] Exemplarily, the extension length of the first slide rail 311 is close to the length of the operating bed body 300, so that the medical support member connecting device and the support member have a larger displacement adjustment range in the length direction, which can meet the support requirements of both the head end side and the foot end side.

[0126] It should be noted that the first fixture 36 may also have a second locking member for locking the first fixture 36 on the first slide rail 311. For example, when the first fixture 36 needs to be slid, the second locking member is released so that the first fixture 36 can slide on the first slide rail 311. When the support member and the medical support member connecting device are moved to the desired position, force is applied to the second locking member, and the second locking member locks the first fixture 36 on the first slide rail 311. At this time, the first fixture 36 cannot slide at will.

[0127] The specific structure of the second locking member is not limited, for example, it can be a screw, the end of the screw passes through the first fixer 36 and abuts against the first slide rail 311, so that the first fixer 36 can be locked on the first slide rail 311.

[0128] The support member is a substantially rectangular support plate 200 , and the support plate 200 has a support surface 200 a for supporting contact with the medical object.
