Fig. 1 and 2 show a schematic structural diagram of a bracket 100 according to an embodiment of the present invention, fig. 3 shows an exploded schematic diagram of the bracket 100, and fig. 4 shows a cross-sectional view of the bracket 100. As shown in fig. 1 to 4, the bracket 100 includes a mounting assembly 1000, an adjusting assembly 2000, and a first adapter 3000. Wherein the mounting assembly 1000 is used to mount the bracket 100 to the target 200 (as shown in fig. 9 and 10), the mounting assembly 1000 includes a fixing portion 1100. The adjustment assembly 2000 connects the fixed portion 1100 and the first adapter 3000. A portion of the structure of the adjustment assembly 2000 is configured to move relative to the fixed portion 1100, thereby moving the first adapter 3000 relative to the fixed portion 1100, thereby changing the relative orientation of the first adapter 3000 and the mounting assembly 1000 and causing the first adapter 3000 to be in a predetermined orientation. In actual use, the connection portion 3100 is configured to connect with a target device (not shown in the figure), and the predetermined orientation is a mounting orientation required for the target device, and the target device can be used normally when the target device is connected to the first adapter 3000 in the predetermined orientation.

In the stand 100 provided by the embodiment of the present invention, the adjusting assembly 2000 is provided, so that the relative orientation of the first adapter 3000 and the mounting assembly 1000 is not fixed, so that when the stand 100 is mounted on the target 200, the orientation of the first adapter 3000 relative to the mounting assembly 2000 can be adjusted according to the orientation of the target 200 by the movement of the movable structure in the adjusting assembly 2000, so that the first adapter 3000 is located at the mounting orientation required by the target device. In this way, it is ensured that the target device can be used normally when it is connected to the first adapter 3000. That is, the direction of the object 200 is not strictly limited during the actual use of the bracket 100 provided by the embodiment of the present invention, and the object 200 may be a member arranged laterally as shown in fig. 9, a member arranged vertically as shown in fig. 10, or a member arranged obliquely (not shown in the drawings), which greatly increases the application range and the application scenario of the bracket 100. In addition, the target device includes, but is not limited to, a medical apparatus.

Optionally, with continued reference to fig. 1-4, the adjustment assembly 2000 includes a first sub-adjustment assembly 2100, a second sub-adjustment assembly 2200, and a second adapter 2300. The first sub-adjustment assembly 2100 is connected to the stationary portion 1100, and a portion of the first sub-adjustment assembly 2100 is configured to be rotatable about a first rotational axis relative to the stationary portion 1100. The second adapter 2300 connects the rotatable structure of the first sub-adjustment assembly 2100 with the second sub-adjustment assembly 2200. A portion of the structure of the second sub-adjustment assembly 2200 is configured to be rotatable about a second axis of rotation. The second axis of rotation intersects or is out of plane with the first axis of rotation. The first adapter 3000 is rotatably connected to the rotatable structure of the second sub-adjustment assembly 2200. In actual use of the stand 100, the rotatable structure of the first sub-adjustment assembly 2100 may be rotated about the first rotational axis to rotate the first adapter 3000 about the first rotational axis to ensure that the orientation of the first adapter 3000 is in a predetermined orientation that is the desired mounting orientation of the medical device, thus ensuring that the medical device attached to the first adapter 3000 is within a range of orientations that may be used normally. In the actual use process, the Su Soudi adapter 3000 and the medical equipment connected with the adapter 3000 can be driven to rotate around the second rotation axis by rotating the rotatable structure of the second sub-adjusting assembly 2200, so that the orientation of the medical equipment can be further adjusted within the usable range, and the operation convenience of a user is improved.

Next, the structure of the respective components of the bracket 100 will be described in detail with reference to fig. 1 to 4, and also with reference to fig. 5 to 8. It should be noted that the following description is only about the available configuration of the stent 100, which is not the only available configuration, and thus should not unduly limit the scope of the present invention.

Referring to fig. 1 to 4, the mounting assembly 1000 further includes a movable portion 1200, and the movable portion 1200 and a part of the members of the fixed portion 1100 form a clamping structure for clamping the target 200, so that the bracket 100 can be mounted on the target 200.

Alternatively, the fixing part 1100 includes a fixing clip 1110, a first connection member 1120, and a second connection member 1130 connected in sequence, and the fixing clip 1110 is disposed opposite to the second connection member 1130. The movable portion 1200 is disposed on the second connection member 1130, the movable portion 1200 includes a movable collet 1210, and the movable collet 1210 is located between the fixed collet 1110 and the second connection member 1130. The movable clamp 1210 is configured to be movable in a predetermined direction to approach or separate from the fixed clamp 1110, so that a region between the movable clamp 1210 and the fixed clamp 1110 constitutes a clamping space to clamp the target 200. That is, the mounting assembly 1000 may clamp the target 200 when the movable clamp 1210 is adjacent to the stationary clamp 1110, and may unclamp the target 200 when the movable clamp 1210 is remote from the stationary clamp 1110, so that the stent may be disengaged from the target 200. Optionally, the predetermined direction is perpendicular to the extending direction of the first rotation axis.

Any suitable means may be used in embodiments of the present invention to drive the movable clamp 1210 in the predetermined direction. In an exemplary implementation, as shown in fig. 1 to 4, the second connecting member 1130 is provided with a threaded through hole (not labeled in the drawings) extending in the predetermined direction, and the movable portion 1200 further includes a threaded connector 1220, one end of the threaded connector 1220 is rotatably connected to the movable chuck 1210, and the other end of the threaded connector 1220 passes through the threaded through hole and extends to a side of the second connecting member 1130 remote from the fixed chuck 1110. The movable clamp 1210 is moved toward or away from the stationary clamp 1110 by applying a force to the screw 1220 such that the screw 1220 rotates and reciprocates in the predetermined direction.

It will be appreciated that the movable portion 1200 may further include a grip portion 1230, the grip portion 1230 being disposed on the threaded connector 1220 on a side of the second connecting member 1130 remote from the stationary collet 1110. The gripping portion 1230 may facilitate the operator to grip and apply force to the threaded connector 1220, and may limit the movement of the threaded connector 1220 away from the second connector 1130. Further, the movable portion 1200 further includes a locking nut 1240, wherein the locking nut 1240 is screwed on the threaded connector 1220 and can be located between the grip portion 1230 and the second connecting member 1130, which is used to lock the threaded connector 1220 from being loosened after the bracket 100 is mounted on the target object 200.

With continued reference to fig. 3 and 4, and in conjunction with fig. 5-7, the first sub-adjustment assembly 2100 includes a first stationary shaft 2110 and a rotatable shaft 2120. The first fixing shaft 2110 is hollow, and the first fixing shaft 2110 is connected to the fixing portion 1100 and is kept relatively stationary with respect to the fixing portion 1100. The rotational shaft 2120 is partially penetrating inside the first fixed shaft 2110, and the rotational shaft 2120 is configured to be capable of rotating around a central axis thereof, that is, a central axis of the rotational shaft 2120 is the first rotational axis. The second adapter 2300 is connected to one end of the rotational shaft 2120, and the second adapter 2300 is held relatively stationary with respect to the rotational shaft 2120 such that the second adapter 2300 rotates about the second rotational axis as the rotational shaft 2120 rotates. The second sub-adjusting assembly 2200 is connected to the second adapter 2300.

In more detail, as shown in fig. 3 and 4, the first connecting member 1120 of the fixing portion 1100 is provided with an inner hole 1121, and the extending direction of the inner hole 1121 is the same as the extending direction of the first rotation axis. Optionally, the first connecting member 1120 includes a first section 1122 and a second section 1123, the first section 1122 extending in the predetermined direction and connecting the stationary collet 1110 and the second connecting member 1130, and the second section 1123 is provided on the first section 1122 and extends in the extending direction of the first rotation axis. The second segment 1123 is provided with the inner bore 1121. The bore 1121 is preferably a stepped counterbore with an opening on the end face of the second segment 1123 remote from the first segment 1122. The first fixing shaft 2110 is inserted into the inner hole 1121 and coupled to the fixing portion 1100 at the inner hole 1121.

As shown in fig. 4 and 7, the first stationary shaft 2110 may include a shaft sleeve 2111 and a joint, which joint of the first stationary shaft 2110 is referred to herein as a first joint 2112. The first engagement portion 2112 is located at an end of the sleeve 2111 remote from the first section 1122 and extends radially outward of the sleeve 2111. When the bracket 100 is assembled, the boss 2111 is inserted into the inner hole 1121 with the first engagement portion 2112 abutting against the stepped surface of the inner hole 1121, and then the first engagement portion 2112 is connected to the stepped surface of the inner hole 1121 with a screw.

The rotational shaft 2120 is partially disposed within the shaft sleeve 2111, and optionally, both ends of the rotational shaft 2120 are located outside the shaft sleeve 2111, and the second adapter 2300 is connected to an end of the rotational shaft 2120 remote from the first section 1122. The first sub-adjustment assembly 2100 further includes a first stop 2130, the first stop 2130 being disposed on an end of the rotational shaft 2120 proximate to the first section 1122, and the first stop 2130 being configured to prevent the rotational shaft 2120 from disengaging the first stationary shaft 2110. Further, the first limiting portion 2130 may be further used for adjusting damping between the first fixing shaft 2110 and the rotating shaft 2120, so as to improve the feel of the user.

In one non-limiting implementation, the rotational shaft 2120 includes a threaded section (not labeled) located at an end of the rotational shaft 2120 proximate to the first section 1122 and located outside the first stationary shaft 2110. The first stopper 2130 includes a pretensioning nut, referred to herein as a first pretensioning nut 2131, and a pretensioning member, referred to herein as a first pretensioning member 2132.

More specifically, the first pre-tightening member 2132 includes a first elastic member 2132a and a first lubricant 2132b, the first elastic member 2132a and the first lubricant 2132b are both sleeved on the outer circumferential surface of the rotational shaft 2120, and the first lubricant 2132b is located at both axial ends of the first elastic member 2132 a. In this embodiment, the first elastic member 2132a is, for example, a shrapnel or a spring, and the first lubricant member 2132b is, for example, an oil pad. When the first pre-tightening nut 2131 is rotated, the elastic potential energy stored in the first elastic member 2132a can be increased when the pre-tightening nut 2131 is moved in a direction approaching the first fixed shaft 2110, so as to increase the damping between the first fixed shaft 2110 and the rotating shaft 2120, and conversely, the elastic potential energy stored in the first elastic member 2132a can be decreased when the first pre-tightening nut 2131 is moved in a direction separating from the first fixed shaft 2110, so as to decrease the damping between the first fixed shaft 2110 and the rotating shaft 2120. The use of the first lubricant 2132b may reduce friction between components, reduce wear, and increase the service life of the first sub-adjustment assembly 2100.

Further, to facilitate connection of the rotational shaft 2120 and the second adapter 2300, in this embodiment, the rotational shaft 2120 includes a mandrel 2121 and a second engagement portion 2122.

Preferably, the pin in this embodiment is a knob plunger (also referred to as an indexing pin), and there is no particular limitation on the type of the knob plunger, which may be a reset type, a self-locking type, or other types. Alternatively, the number of the second pin holes is eight, and the eight second pin holes are uniformly arranged around the first rotation axis, so that the eight angles of the first adapter 3000 can be adjusted by the rotation of the rotation shaft 2120.

Fig. 8 shows the overall structure of the second sub-adjustment assembly 2200. As shown in fig. 8, the second sub-adjusting assembly 2200 includes a second fixed shaft 2210 and a rotating disk 2220. The second fixed shaft 2210 is connected to the second adapting block 2320 of the second adapter 2300, and the second fixed shaft 2210 is kept relatively stationary with the second adapter 2300. The rotating disc 2220 is sleeved on the second fixed shaft 2210, and the rotating disc 2220 can rotate around the central axis of the second fixed shaft 2210, so that the central axis of the second fixed shaft 2210 is the second rotation axis. The first adapter 3000 may be coupled to the rotating disk 2220 by screws or any other suitable means, and the first adapter 3000 may remain relatively stationary with the rotating disk 2220.

The second fixed shaft 2210 may include a shaft body 2211 and a third joint 2212. Referring to fig. 4, the shaft body 2211 includes a first shaft section (not labeled in the drawing) and a second shaft section (not labeled in the drawing) connected to each other, wherein the diameter of the first shaft section is larger than that of the second shaft section, so that an intersection between the first shaft section and the second shaft section forms a limiting step (not labeled in the drawing). The rotating disk 2220 is sleeved on the second shaft section. The third engagement portion 2222 is provided on the first shaft section and extends radially outward of the shaft body 2211. The third engagement portion 2212 can be coupled to the second adapter 2320 of the second adapter 2300 by a screw or any other suitable means. The shape of the third engagement portion 2122 is not particularly limited in the embodiment of the present invention, and may be set as needed. Meanwhile, as shown in fig. 4 and 8, the second sub-adjusting assembly 2200 further includes a second limiting portion 2230, the second limiting portion 2230 is disposed on a side of the rotating disc 2220 away from the limiting step, and the second limiting portion 2230 cooperates with the limiting step to prevent the rotating disc 2220 from being separated from the second fixed shaft 2210. Further, the second stopper 2230 is also configured to adjust damping between the second fixed shaft 2210 and the rotating disc 2220.

Alternatively, the second stopper 2230 has substantially the same configuration as the first stopper 2130. In other words, the second shaft section of the shaft body 2211 is provided with a thread, the second limiting portion 2230 includes a second pre-tightening nut 2231 and a second pre-tightening member 2232, the second pre-tightening nut 2231 is screwed on the second shaft section, the second pre-tightening member 2232 is sleeved on the outer peripheral surface of the second shaft section, and two axial ends of the second pre-tightening member 2232 respectively abut against the second pre-tightening nut 2231 and the rotating disc 2220. The second pre-tightening member 2232 includes a second elastic member 2232a and a second lubricant member 2232b, the second elastic member 2232a and the second lubricant member 2232b are both sleeved on the outer circumferential surface of the second shaft section, and the second lubricant member 2232b is located at two axial ends of the second elastic member 2242 a. When the second pre-tightening nut 2231 is rotated to move the second pre-tightening nut 2231 in a direction approaching the rotating disk 2220, the elastic potential energy stored by the second elastic member 2242a increases, so that the damping between the second fixed shaft 2210 and the rotating disk 2220 increases. Conversely, when the second pre-tightening nut 2231 moves in a direction away from the rotating disk 2220, the elastic potential energy stored by the second elastic member 2242a decreases, so that damping between the second fixed shaft 2210 and the rotating disk 2220 decreases.

In practice, the damping between the rotating disk 2220 and the second fixed shaft 2210 may be set to be greater than the damping between the rotating shaft 2120 and the first fixed shaft 2110. When the damping between the rotating disc 2220 and the second stationary shaft 2210 is sufficiently large and proper, the rotating disc 2220 can be kept relatively stationary with the second stationary shaft 2210 without external force by the interaction of the self weight of the medical device connected to the first adapter 3000 and the damping between the rotating disc 2220 and the first stationary shaft 2210. In this case, if the user needs to rotate the rotating disc 2220 to adjust the orientation of the medical device, the user may directly apply an acting force to the medical device, and the acting force is transmitted to the rotating disc 2220 through the medical device, so as to drive the rotating disc 2220 to rotate, which is more convenient and more direct to operate.

Optionally, the second sub-adjustment assembly 2200 may further include a third limiting portion (not shown) for limiting the rotation angle of the rotating disk 2220. For example, the third limiting portion may include two first stoppers and one second stopper, the two first stoppers may be disposed on an outer circumferential surface of the second shaft section and arranged at intervals along a circumferential direction of the first shaft section, the second stopper may be disposed on a surface of the rotating disk 2220 away from the first shaft section, and the second stopper may be disposed between the two first stoppers. When the rotating disk 2220 rotates in a first direction to contact one of the first stoppers, the rotating disk 2220 cannot continue to rotate in the first direction, and when the rotating disk rotates in a second direction to contact the other of the first stoppers, the rotating disk 2220 cannot continue to rotate in the second direction. The second direction is opposite to the first direction. Alternatively, the two first stoppers are spaced apart by 180 ° such that the maximum rotation angle of the rotating disk 2220 is 180 °.

In addition, a counterbore is provided on the end surface of the first adapter block 2310 facing the rotational shaft 2120 to accommodate the second adapter 2122. The second adapter 2320 is provided with a counterbore to accommodate the third joint 2122. The first adapter 3000 has a stepped counterbore to accommodate the portion of the second sub-assembly 2200 protruding from the second adapter 2320. This has the advantage of hiding the screws, the first sub-adjustment assembly 2100, the second sub-adjustment assembly 2200, etc., which may make the stand 100 aesthetically pleasing.

The manner in which the stent 100 is actually used will be described below by way of example.

As shown in fig. 1, the first adapter 3000 is provided with a connection portion 3100, and the first adapter 3000 is connected to the medical device through the connection portion 3100. The connection portion 3100 may be a socket provided on an end of the first adapter 3000 remote from the first adapter block 2310, for inserting a plug of the medical device so that the medical device is connected to the bracket 100. When the plug interface is in a predetermined orientation, the medical device connected to the first adapter 3000 can be brought into a predetermined orientation and normal use can be ensured. Taking the medical device as an oxygenator for example, when the oxygenator is connected to the first adapter 3000, the oxygenator should be disposed vertically and not inverted for normal use, which requires that the plug interface be above the second adapter 2320.

Referring again to fig. 9, when the bracket 100 is mounted to a laterally disposed elongated member, the first axis of rotation extends in a horizontal direction. The rotation of the rotation shaft 2120 of the first sub-adjusting assembly 2100 drives the second adapter 2300 and the first adapter 3000 thereon to rotate around the first rotation axis, so that the first adapter 3000 rotates to the upper side of the second adapter 2320, and thus, the plug is located above the second adapter 2320. At the same time, the second rotation axis extends in a vertical direction. When the oxygenator is actually used, the first adapter 3000 can be driven to rotate around the second rotation axis by the rotation of the rotating disc 2220, so that the first adapter 3000 swings on the horizontal plane, and in this process, the plug is always located above the second adapter 2320, so that the oxygenator can be normally used all the time.

Referring again to fig. 10, when the bracket 100 is mounted to a vertically disposed elongated member, the first rotational axis still extends in a horizontal direction. In this case, the second adapter 2300 and the first adapter 3000 thereon can still be rotated about the first rotation axis by the rotation of the rotation shaft 2120 until the first adapter 3000 rotates above the second adapter 2320, such that the plug is located above the second adapter 2320. While the second rotation axis is made to extend in the vertical direction.

As can be seen from this application example, the bracket 100 provided by the embodiment of the present invention rotates the first adapter 3000 through the rotation of the rotatable structure of the first sub-adjusting assembly 2100, so that the connection portion 3100 on the first adapter 3000 is in a predetermined orientation, so as to meet the installation requirement of the medical device. And the first adapter 3000 and the medical device thereon may be oscillated through rotation of the rotatable structure of the second sub-adjustment assembly 2200 within a usable range of orientations to further facilitate user operation.

The support provided by the embodiment of the invention is small and exquisite in whole and is convenient to carry. The support has two degrees of rotation freedom, so that the support can be connected with targets in various directions to ensure that medical equipment connected to the first adapter can still be used normally, and the application scene of the support is enlarged. In addition, the damping of two sub-adjusting components of the support is adjustable, so that a user can adjust the damping of two sub-adjusting components according to personal habits and use scenes, and use experience is improved.

Although the present invention is disclosed above, it is not limited thereto. Various modifications and alterations of this invention may be made by those skilled in the art without departing from the spirit and scope of this invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
