Embodiment of the transmission structure
The embodiment of the utility model provides a transmission structure, as shown in fig. 1 to 3, the transmission structure 1 is used for connecting and transmitting a driving box 2 and an aseptic box 3 of a vascular interventional operation robot, wherein the driving box 2 is provided with a driving shaft 21, the aseptic box 3 is provided with a power input end (not shown in fig. 1 to 3), the transmission structure 1 is detachably arranged on one side of the aseptic box 3 facing the driving box 2 and is connected with the power input end inside the aseptic box 3, when the driving box 2 and the aseptic box 3 are connected through the transmission structure 1, the transmission structure 1 is in alignment connection with the driving shaft 21, and the transmission structure 1 is detachably connected with the driving shaft 21.
In this embodiment, as shown in fig. 4, the transmission structure 1 includes a first rotating member 11 and a floating mechanism 12, the floating mechanism 12 is used for floating connection between the first rotating member 11 and the driving shaft 21, and the first rotating member 11 is connected to the power input end for transmission. Specifically, when the floating mechanism 12 is mounted on the side of the aseptic box 3 facing the driving box 2, the first rotating member 11 is connected with the power input end inside the aseptic box 3, and when the driving box 2 and the aseptic box 3 are connected through the transmission structure 1, the floating mechanism 12 can be connected with the driving shaft 21 in an alignment manner.
During the mounting of the sterile cassette 3 to the drive cassette 2 via the transmission 1, the transmission 1 has two initial mating relations with the drive shaft 21.
The first initial matching relationship is that the transmission structure 1 and the driving shaft 21 are accurately aligned, the floating mechanism 12 and the driving shaft 21 are directly connected in an aligned manner, the sterile box 3 is still in positioning and butting connection with the driving box 2, the floating mechanism 12 is driven to rotate through the rotation of the driving shaft 21, the first rotating member 11 is driven to rotate, and power is transmitted to the structure inside the sterile box 3 through the power input end, so that the medical instruments such as a catheter or a guide wire (such as the forward, backward and rotation of the guide wire or the catheter) are driven inside the sterile box 3.
The second initial matching relationship is that the alignment of the transmission structure 1 and the driving shaft 21 is inaccurate, the driving shaft 21 is propped against the floating mechanism 12, the floating mechanism 12 is propped up and moves towards the direction of the sterile box 3, the sterile box 3 can still be correctly positioned and butted with the driving box 2, but power transmission cannot be carried out, on the basis, when the driving shaft 21 rotates, the driving shaft 21 can be aligned with the floating mechanism 12 in the rotating process, after the alignment, the floating mechanism 12 is reset to be connected with the driving shaft 21 in an alignment manner, the floating mechanism 12 is driven to rotate through the rotation of the driving shaft 21, the first rotating member 11 is driven to rotate, and power is transmitted to the structure inside the sterile box 3 through the power input end.

Further, as shown in fig. 7, the second rotating member 122 is provided with at least one first insertion portion 1221 for connecting with the first rotating member 11, and, as shown in fig. 6, the inner wall of the accommodating cavity 112 of the first rotating member 11 is provided with a first groove 113 extending along the axial direction corresponding to the first insertion portion 1221; in the circumferential direction of the first rotating member 11, the width of the first plugging portion 1221 is smaller than the width of the first groove 113, so that the first plugging portion 1221 may be slidably connected with the first groove 113 along the axial direction of the first rotating member 11, and on the other hand, when the driving shaft 21 drives the second rotating member 122 to rotate, the first plugging portion 1221 located in the first groove 113 applies a circumferential force to the protruding portion 111, thereby driving the first rotating member 11 to rotate, so as to realize that the second rotating member 122 drives the first rotating member 11 to coaxially rotate through the first plugging portion 1221.
In this embodiment, the second rotating member 122 is detachably connected to the driving shaft 21, and the second rotating member 122 can compress the elastic member 121 under force when the second rotating member is in dislocation butt joint with the driving shaft 21, moves axially toward the first rotating member 11, and can be reset to connect the driving shaft 21 in alignment during the rotation of the driving shaft 21. Specifically, with reference to the above-mentioned two initial mating relationships between the transmission structure 1 and the driving shaft 21 during the process of mounting the sterile cassette 3 to the driving cassette 2 through the transmission structure 1, correspondingly, in the first initial mating relationship, the second rotating member 122 is aligned with the driving shaft 21, while in the second initial mating relationship, the second rotating member 122 is dislocated with the driving shaft 21, at this time, the second rotating member 122 will move axially towards the first rotating member 11 under the action of the driving shaft 21, and the elastic member 121 is compressed, on the basis that, when the driving shaft 21 rotates, the driving shaft 21 can be aligned with the second rotating member 122 during the rotation, and the elastic member 121 pushes the second rotating member 122 to reset, so as to realize the alignment connection between the second rotating member 122 and the driving shaft 21.

In some embodiments, the second mating portion 1222 is a second recess, and the mating portion 211 is a bump. In other embodiments, the second mating portion 1222 is a bump, and the mating portion 211 is a second groove.
