[0042] Embodiment one of the trolley device of the present application

[0043] Please refer to Figure 1 As shown in the drawings, the embodiment of the present application provides a trolley device, which is used for carrying an interventional robot (not shown in the drawings) to a surgical bed (not shown in the drawings) and positioning and matching with the surgical bed, so that the interventional robot can be accurately installed on the surgical bed.

[0044] In some embodiments, the trolley device comprises a mounting seat 10 and at least one auxiliary positioning mechanism 20, wherein the mounting seat 10 has a first end close to the operating table and a second end away from the operating table, and the auxiliary positioning mechanism 20 is arranged on the mounting seat 10, so that when the trolley device is close to the operating table, the auxiliary positioning mechanism 20 is positioned with the bedside rail of the operating table, serving as a positioning reference for the interventional robot before being carried to the operating table, thereby improving the installation accuracy and efficiency of the interventional robot. Please continue to refer to Figure 1 In the present embodiment, as shown in the drawings, the operating table is provided with a positioning assembly (not shown in the drawings) cooperating with the auxiliary positioning mechanism 20. In the present application, the first end of the mounting seat 10 can be understood as the end of the mounting seat 10 close to the positioning assembly (i.e. the A end or A' end in Figure 1 ), and the second end of the mounting seat 10 can be understood as the end of the mounting seat 10 away from the positioning assembly (i.e. the B end or B' end in Figure 1 ). Please refer to Figure 2 , Figure 3 In some embodiments, the auxiliary positioning mechanism 20 comprises a positioning member 1 and a locking member 2. The positioning member 1 is movably arranged on the mounting seat 10, and has an abutting portion 13. The positioning member 1 is provided with a locking structure cooperating with the locking member 2. The locking member 2 is arranged on the mounting seat 10.

[0045] During the movement of the positioning member 1 towards the first end, the locking member 2 cooperates with the locking structure to lock the positioning member 1 at the first end of the mounting seat 10, so that the abutting portion 13 abuts against the operating table, and the auxiliary positioning mechanism 20 is accurately positioned with the operating table. When the locking member 2 is disengaged from the locking structure, the positioning member 1 moves towards the second end, and the abutting portion 13 is separated from the operating table.

[0046] The trolley device provided by the present application comprises an auxiliary positioning mechanism 20 arranged on the mounting seat 10, which is accurately positioned with the operating table by cooperating with the operating table, so that the interventional robot can be accurately arranged on the operating table, thereby improving the installation efficiency and quality of the interventional robot. Meanwhile, the locking structure cooperates with the locking member 2 to lock and unlock the positioning member 1. During the positioning of the trolley device, the positioning member 1 is locked and fixed to avoid the rotation of the positioning member 1 caused by external force, thereby improving the accuracy of the positioning of the auxiliary positioning mechanism 20 and the operating table. After the positioning of the trolley device is completed, the positioning member 1 is unlocked and reset to avoid affecting the installation and fixation of the interventional robot, thereby improving the installation efficiency of the interventional robot.

[0047] In some embodiments, the mounting manner of the positioning member 1 on the mounting base 10 can be that the positioning member 1 is horizontally movably mounted on the mounting base 10, and during the alignment of the trolley device, the positioning member 1 is horizontally slid from the second end (i.e., the B end in Figure 1 ) of the mounting base 10 to the first end (i.e., the A end in Figure 1 ) of the mounting base 10.

[0048] In some embodiments, the mounting manner can also be that the positioning member 1 is pivotally mounted on the mounting base 10 near the operating bed, and during the alignment of the trolley device, the positioning member 1 is pivoted about the pivot 11 so that the abutting portion 13 of the positioning member 1 is pivoted from the second end (i.e., the B end in Figure 1 ) of the mounting base 10 to the first end (i.e., the A end in Figure 1 ) of the mounting base 10, or so that the abutting portion 13 of the positioning member 1 is upwardly flipped from the second end (i.e., the B' end in Figure 1 ) of the mounting base 10 to the first end (i.e., the A' end in Figure 1 ) of the mounting base 10.

[0049] In some embodiments, the mounting manner can also be that the positioning member 1 is vertically movably mounted on the mounting base 10 near the operating bed, and during the alignment of the trolley device, the positioning member 1 is vertically slid from the second end (i.e., the B' end in Figure 1 ) of the mounting base 10 to the first end (i.e., the A end in Figure 1 ) of the mounting base 10.

[0050] In the present embodiment, the auxiliary positioning mechanism 20 is mounted on the first end of the mounting base 10, and the number of the auxiliary positioning mechanism 20 is two, and the two auxiliary positioning mechanisms 20 are mounted on opposite sides of the first end of the mounting base 10 so that the mounting base 10 can be aligned with the bed rail of the operating bed. In the present embodiment, the positioning member 1 is pivotally mounted on the mounting base 10 by the pivot 11, and when the auxiliary positioning mechanism 20 is in the initial state, the positioning member 1 is in the horizontal state and is retracted into the mounting base 10, as shown in Figure 2 ; when the trolley device approaches the operating bed and needs to be positioned, the positioning member 1 is pivoted relative to the mounting base 10 to the vertical state, as shown in Figure 3 .

[0051] Please refer to Figure 2 , in some embodiments, the locking structure includes a guide portion 12, and the guide portion 12 includes a locking groove 123.

[0052] The locking piece 2 is rotatably arranged on the mounting seat 10 through the guide part 12. In the embodiment, the auxiliary positioning mechanism 20 further comprises a rotating shaft (not shown in the figure) which is rotatably arranged on the mounting seat 10 through the guide part 12, and the locking piece 2 is rotatably arranged on the rotating shaft.

[0053] The locking piece 2 cooperates with the guide part 12 to guide and limit the rotation of the positioning piece 1 around the pivot 11. Meanwhile, the locking piece 2 cooperates with the locking groove 123 to lock the positioning piece 1, so as to avoid the rotation of the positioning piece 1 caused by external force, thereby improving the positioning accuracy of the auxiliary positioning mechanism 20 and the operating table.

[0054] As shown in Figure 2 , Figure 3 In some embodiments, the opposite ends of the locking piece 2 are symmetrically provided with a first clamping tenon 21 and a second clamping tenon 22, the first clamping tenon 21 and the second clamping tenon 22 are the same in shape, and the first clamping tenon 21 and the second clamping tenon 22 are matched with the shape of the locking groove 123.

[0055] The shape of the locking piece 2 is set to enable the opposite ends of the locking piece 2 to be locked with the locking groove 123, thereby improving the locking stability of the positioning piece 1 and facilitating installation.

[0056] In some embodiments, the guide part 12 comprises a guide sliding groove 121, a first turning groove 122, the locking groove 123 and a second turning groove 124.

[0057] In the embodiment, the guide sliding groove 121 is an arc-shaped groove with the pivot 11 as the center. When the positioning piece 1 rotates around the pivot 11, the rotating shaft moves along the guide sliding groove 121 to guide and limit the rotation of the positioning piece 1.

[0058] The first turning groove 122 is located in the extension direction of the guide sliding groove 121, and is used to guide the rotation of the locking piece 2 so that the first clamping tenon 21 or the second clamping tenon 22 is aligned with the locking groove 123.

[0059] The locking groove 123 is located on the opposite side of the first turning groove 122.

[0060] The second turning groove 124 is located between the first turning groove 122 and the locking groove 123, and is used to guide the rotation of the locking piece 2 so that the first clamping tenon 21 or the second clamping tenon 22 is misaligned with the locking groove 123.

[0061] Please refer toFigure 2 、 Figure 3 As shown in FIG. 1, when the trolley device approaches the operating bed, the driving positioning member 1 rotates around the pivot 11 towards the direction of approaching the operating bed, and the locking member 2 moves along the guide sliding groove 121. With the change of the rotating angle of the positioning member 1, the locking member 2 enters the first turning groove 122, and under the guidance of the groove wall of the first turning groove 122, the locking member 2 rotates around the rotating shaft to the parallel direction of the locking groove 123. Then, the driving positioning member 1 rotates around the pivot 11 towards the direction of moving away from the operating bed, and the locking member 2 moves from the first turning groove 122 to the locking groove 123. The first tenon 21 is placed into the locking groove 123, and through the cooperation of the first tenon 21 and the locking groove 123, the further rotation of the positioning member 1 towards the direction of moving away from the operating bed is limited, the locking and fixing of the positioning member 1 are realized, and the positioning member 1 is in the vertical state, as shown in FIG. 2. Figure 3

[0062] When the auxiliary positioning mechanism completes the auxiliary positioning function, the interventional robot needs to be installed on the operating bed. At this time, the positioning member 1 needs to be reset, so as to avoid affecting the subsequent installation of the interventional robot.

[0063] In this embodiment, the driving positioning member 1 rotates around the pivot 11 towards the direction of approaching the operating bed, so that the first tenon 21 exits from the locking groove 123. With the rotation of the positioning member 1, the second tenon 22 enters the second turning groove 124, and under the guidance of the groove wall of the second turning groove 124, the locking member 2 rotates around the rotating shaft, so that the locking member 2 is dislocated with the locking groove 123. Then, the driving positioning member 1 rotates around the pivot 11 towards the direction of moving away from the operating bed, and the locking member 2 moves along the guide sliding groove 121. Since the locking member 2 is dislocated with the locking groove 123, when the locking member 2 approaches the locking groove 123 again, the first tenon 21 is dislocated with the locking groove 123, and the locking member 2 cannot form cooperation with the locking groove 123. The locking member 2 moves along the guide sliding groove 121 to the end of the positioning member 1, and the positioning member 1 is reset to the horizontal state, as shown in FIG. 3. Figure 2

[0064] In this embodiment, the shape of the guide part 12 is set to realize the guiding and limiting effect on the rotation of the positioning member 1 through cooperation with the locking member 2. Meanwhile, through the setting of the first turning groove 122 and the locking groove 123, the rotation of the locking member 2 is guided during the rotation of the positioning member 1 around the pivot 11, so that the first tenon 21 can be accurately matched with the locking groove 123, thereby realizing the locking of the positioning member 1 and ensuring the accurate alignment of the trolley device and the operating bed. Furthermore, through the setting of the second turning groove 124, the locking member 2 can be further guided to rotate, thereby releasing the locking of the positioning member 1, so that the positioning member 1 can be reset and the subsequent installation of the interventional robot is not affected.

[0065] ​​Please refer to Figure 2 , Figure 3 In some embodiments, the second turning groove 124 is formed with a set angle a between the groove wall on one side of the first turning groove 122 and the locking groove 123, wherein the set angle a is 30-90°, and specifically, the set angle a can be set to any one of 30°, 45°, 60°, 75°, 90° or a range formed between any two values.

[0066] In the embodiments, the rotation angle of the locking member 2 is adjusted by limiting the set angle a, so that the first clamping tenon 21 is misaligned with the locking groove 123 during the resetting of the positioning member 1, the locking of the positioning member 1 is released, and the positioning member 1 can be reset by rotating around the pivot.

[0067] In the embodiments, the width of the guide sliding groove 121 is the same as the width of the locking member 2 or the width of the guide sliding groove 121 is 1.2-1.5 times the width of the locking member 2.

[0068] In the embodiments, the shape and width of the guide sliding groove 121 are set, so that the locking member 2 can smoothly enter the guide sliding groove 121 during the rotation of the positioning member 1 around the pivot 11, thereby improving the resetting efficiency of the locking member 2.

[0069] Please refer to Figures 1 to 3 In some embodiments, the positioning member 1 further comprises a buffer member 17, which is arranged on the side of the abutting portion 13 in contact with the operating bed.

[0070] In the embodiments, the trolley device further comprises a buffer gasket 30, which is arranged on the side of the mounting seat 10 close to the operating bed.

[0071] The buffer member 17 and the buffer gasket 30 are selected from one of a rubber member and a silica gel member.

[0072] In the embodiments, the buffer member 17 is arranged on the abutting portion 13 of the positioning member 1, and the buffer gasket 30 is arranged on the mounting seat 10, so that the abutting portion 13 of the positioning member 1 and the mounting seat 10 do not collide with and damage the operating bed during the auxiliary positioning of the trolley device close to the operating bed.

[0073] Embodiment two of the trolley device of the application

[0074] Please refer to Figure 3 , Figure 4 In the embodiments, the trolley device is different from the first embodiment in the structure of the auxiliary positioning mechanism 20, and the specific differences are as follows:

[0075] The positioning member 1 is rotatably arranged on the mounting base 10 through a pivot 11, and the positioning member 1 can slide along the axial direction of the pivot 11, wherein the locking structure comprises at least one alignment member 14.

[0076] The locking member 2 is fixedly arranged on the mounting base 10, and at least one first limiting groove 23 is arranged on the side of the locking member 2 facing the positioning member 1, the alignment member 14 is matched with the first limiting groove 23, and the alignment member 14 is used for limiting the rotation of the positioning member 1 around the pivot 11.

[0077] The auxiliary positioning mechanism 20 further comprises a pressing assembly 3 arranged on the pivot 11 and located on the side of the positioning member 1 away from the mounting base 10, and the pressing assembly 3 is used for pushing the positioning member 1 to move along the pivot 11 to the side of the locking member 2, so that the alignment member 14 is arranged in the first limiting groove 23.

[0078] In some embodiments, when the alignment member 14 is separated from the first limiting groove 23, the positioning member 1 can rotate around the pivot 11 to the first end of the mounting base 10 or to the second end of the mounting base 10.

[0079] The auxiliary positioning mechanism 20 of the trolley device provided by the embodiment of the present application realizes the locking of the positioning member 1 through the matching between the alignment member 14 and the first limiting groove 23, and meanwhile, the setting of the pressing assembly 3 can ensure that the alignment member 14 is stably arranged in the first limiting groove 23 without external force, so as to avoid the rotation of the positioning member 1 caused by accidental contact of external force, thereby improving the accuracy of the positioning cooperation between the auxiliary positioning mechanism 20 and the operating bed. In addition, the positioning member 1 in the embodiment can slide along the axial direction of the pivot 11, which can cause the positioning member 1 and the locking member 2 to be misaligned, thereby releasing the locking of the positioning member 1, so as to facilitate the rotation of the positioning member 1 around the pivot 11 to reset, avoid affecting the installation and fixation of the interventional robot, and improve the installation efficiency of the interventional robot. Please refer to Figure 3 、 Figure 4 In some embodiments, the positioning member 1 is provided with a mounting groove 15 on the side facing the mounting base 10, and the alignment member 14 is arranged in the mounting groove 15. In the embodiment, the number of the alignment member 14 is two, specifically, a first alignment member 141 and a second alignment member 142, and the first alignment member 141 and the second alignment member 142 form an included angle of 90°.

[0080] In the embodiment, the locking member 2 is at least partially arranged in the mounting groove 15, so that the alignment member 14 can be arranged in the first limiting groove 23, and the locking cooperation between the alignment member 14 and the first limiting groove 23 is realized.

[0081] In the embodiment, the length of the pivot 11 is greater than or equal to the sum of the groove depth of the mounting groove 15 and the thickness of the locking member 2. The embodiment limits the length of the pivot 11, so that the positioning member 1 can be misaligned with the locking member 2, the locking member 2 is out of the mounting groove 15, the alignment member 14 is out of the first limiting groove 23, the restriction of the positioning member 1 by the locking member 2 is released, so that the positioning member 1 can be reversely rotated and reset, and the installation of the positioning member 1 on the intervening robot is avoided.

[0082] Please refer to Figure 4 In some embodiments, the alignment member 14 is provided with a first guide inclined surface 143 on one side of the first end of the mounting base 10. In the embodiment, the first guide inclined surface 143 is outwardly protruded from the top surface to the bottom surface on one side of the first end of the mounting base 10, and the cross section of the alignment member 14 is in a right-angled trapezoidal shape.

[0083] In the embodiment, when the positioning member 1 rotates around the pivot 11 to the first end of the mounting base 10, the alignment member 14 pushes the positioning member 1 to move along the pivot 11 away from the locking member 2 through the guidance of the first guide inclined surface 143, so that the alignment member 14 is out of the first limiting groove 23 and the locking of the positioning member 1 is released.

[0084] The first guide inclined surface 143 on the alignment member 14 can push the positioning member 1 to be misaligned with the locking member 2 and temporarily release the locking of the positioning member 1. Since the other side of the alignment member 14 cannot push the positioning member 1 to be misaligned with the locking member 2, the shape of the alignment member 14 ensures that the positioning member 1 can only rotate around the pivot 11 to a designated direction until the abutting portion 13 moves to the abutting position and abuts against the operating table.

[0085] Please refer to Figure 4 、 Figure 5 In some embodiments, the locking member 2 is provided with at least two first limiting protrusions 24 on one side of the mounting base 10. The first limiting groove 23 is formed between two adjacent first limiting protrusions 24. The first limiting protrusion 24 is provided with a second guide inclined surface 241 on one side of the second end of the mounting base 10. In the embodiment, the second guide inclined surface 241 is inwardly inclined from the top surface to the bottom surface. The first limiting protrusion 24 is provided with a stop table on the side away from the second guide inclined surface 241. The cross section of the first limiting protrusion 24 is in an inverted right-angled trapezoidal shape.

[0086] In the embodiment, when the positioning member 1 rotates around the pivot 11 to the first end of the mounting base 10, the second guide slope 241 guides the disengagement of the alignment member 14 from the first limiting groove 23, thereby releasing the locking of the positioning member 1; the stop table is used to limit the movement of the alignment member 14 towards the second end of the mounting base 10, thereby limiting the unidirectional rotation of the positioning member 1.

[0087] In the embodiment, the second guide slope 241 is arranged on the first limiting protrusion 24, which can temporarily release the locking of the positioning member 1 by dislocating the positioning member 1 and the locking member 2; meanwhile, the other side of the first limiting protrusion 24 cannot dislocate the positioning member 1 and the locking member 2, so the shape of the first limiting protrusion 24 is arranged to ensure that the positioning member 1 can only rotate around the pivot 11 in a set direction until the abutting portion 13 moves to the abutting position and abuts against the operating table.

[0094] In the embodiment, the length of the pivot 11 is greater than or equal to the sum of the groove depth of the mounting groove 15 and the thickness of the locking member 2. After the auxiliary positioning mechanism 20 completes the auxiliary positioning function, the interventional robot needs to be installed on the operating table, at this time, the positioning member 1 needs to be reset, thereby avoiding affecting the installation of the interventional robot.

[0095] In the embodiment, the positioning member 1 is moved along the pivot 11 away from the locking member 2, so that the locking member 2 is separated from the mounting groove 15 of the positioning member 1, and the limitation of the locking member 2 on the positioning member 1 is released, so that the positioning member 1 can rotate reversely around the pivot 11 to recover to the horizontal state.

[0096] The embodiment of the present application limits the length of the pivot 11, so that the positioning member 1 can be dislocated with the locking member 2, the limitation of the locking member 2 on the positioning member 1 is released, so that the positioning member 1 can rotate reversely to reset, avoiding affecting the installation of the interventional robot by the positioning member 1; at the same time, through the setting of the limiting baffle 31, the positioning member 1 is prevented from being separated from the pivot 11 during the movement of the positioning member 1 along the pivot 11, ensuring the structural stability of the auxiliary positioning mechanism 20.

[0097] Under the condition of no external force, the elastic member 32 pushes the positioning member 1 to move towards the locking member 2 through the elastic action of itself, so that the locking member 2 can be stably placed into the mounting groove 15 of the positioning member 1, the positioning member 1 and the locking member 2 maintain the locking cooperation relationship, the locking member 2 can play a locking role on the positioning member 1, ensuring that the positioning member 1 can rotate to the set position, thereby playing the role of auxiliary positioning.
