Description

Technical Field

[0001] This application relates to the field of medical device assistive technology, specifically to a support module, support device, and interventional medical system. Background Technology

[0002] Interventional devices are temporary medical tools that enter the body through natural cavities or minimally invasive incisions for diagnosis or treatment. They are characterized by minimal invasiveness, precision, and reversibility, and aim to assist in treatment and disease control.

[0003] Minimally invasive surgery, characterized by small incisions, rapid recovery, and fewer complications, has gradually become a hot topic in various surgical disciplines in recent years. Minimally invasive surgery requires surgeons to operate surgical instruments simply, quickly, and stably to ensure the stability and safety of the instruments, as well as the patient's safety during the procedure. Therefore, support devices for fixing interventional instruments have emerged. During the surgery, the position of the interventional instrument or its handle on the support device often needs to be adjusted according to the surgical requirements. In existing support devices, the support module itself cannot rotate, resulting in the angle of support for the interventional instrument or handle not meeting the surgeon's requirements, thus affecting the stability of the surgery and increasing surgical risks. Utility Model Content

[0004] The main objective of this application is to provide a support module, a support device, and an interventional medical system to solve the problem in the prior art that the support module cannot rotate 360 ​​degrees to adjust the angle of the supported interventional device or handle.

[0005] On the one hand, this application provides a support module, characterized in that it includes:

[0006] First and second pick-up items; and

[0007] A support member, the two ends of which are respectively disposed on the first lifting member and the second lifting member, and are used to support the interventional device or the handle of the interventional device;

[0008] The support member and / or the interventional device and / or the handle of the interventional device can rotate 360 ​​degrees relative to the first and second lifting members under the action of external force, so as to adjust the interventional device or the handle of the interventional device to rotate to a preset angle.

[0009] Furthermore, the first lifting member has a first supporting groove, which is U-shaped, and the second lifting member has a second supporting groove, which is U-shaped.

[0017] Furthermore, the first rotating part has a first limiting groove. When the first rotating part is rotatably limited within the first supporting groove, the first supporting part and the two first limiting parts are respectively limited within the first limiting groove.

[0018] And / or, if the second rotating part has a second limiting groove, and the second rotating part is rotatably limited within the second supporting groove, then the second supporting part and the two second limiting parts are respectively limited within the second limiting groove.

[0019] And / or, both the first and second fasteners are hand-tightening fasteners;

[0024] Furthermore, the support assembly also includes a fourth fixing member, at least one of the limiting plate portions located on the third side of the support plate portion is threadedly connected to the fourth fixing member. When the interventional device or the handle of the interventional device is disposed in the mounting groove and abuts against the limiting plate portion located on the fourth side of the support plate portion, the fourth fixing member abuts against the surface of the interventional device or the handle of the interventional device near the third side.

[0025] The third side and the fourth side are the opposite sides of the support plate portion.

[0026] Furthermore, both the third and fourth fixing members are hand-tightening fixing members;

[0027] And / or, the third fastener elastically abuts against the surface of the interventional device or elastically abuts against the surface of the handle of the interventional device, and the fourth fastener elastically abuts against the surface of the interventional device or elastically abuts against the surface of the handle of the interventional device.

[0029] The system includes a support module and an adjustment module.

[0032] In the support module of this application, the support member supports the interventional device or the handle of the interventional device, and the two ends of the support member are respectively disposed on the first lifting member and the second lifting member. When the interventional device or the handle of the interventional device needs to be rotated, at least one of the support member, the interventional device, and the interventional device or the handle rotates 360 degrees relative to the first lifting member and the second lifting member under the action of external force, thereby adjusting the interventional device or the handle to a preset angle, thereby meeting the operator's angle requirements for the interventional device or the handle during surgery, thereby improving the stability of the surgery and reducing the surgical risk.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0053] Please see Figure 1-5 As shown, this application provides a support device 100, which includes a support module 20, an adjustment module, and a support module 10. The support module 20 includes a track 21; the adjustment module includes a drive unit 31 and a braking unit 32, which are spaced apart on the track 21 along its extension direction and are respectively connected to the support module 10.

[0054] The braking unit 32 has a braking state and a released state. When the braking unit 32 is in the braking state, the braking unit 32 is stationary on the track 21, and the drive unit 31 is stationary on the track 21 by the support module 10 and the interventional instrument or the handle 200 of the interventional instrument it supports, thereby braking the drive unit 31. This allows the braking unit 32 and the drive unit 31 to accurately position the interventional instrument or the handle 200 of the interventional instrument at a designated position on the track 21, so that the surgeon can stably perform the handle 200 operation by using the interventional instrument or the handle 200, thereby improving the stability, efficiency and safety of the surgery.

[0055] When the braking unit 32 is in the released state, the driving unit 31 and the braking unit 32 can also form a synchronously moving whole through the support module 10 and the interventional instrument or the handle 200. Therefore, by simply driving the driving unit 31 to move along the track 21, the position of the interventional instrument or the handle 200 on the track 21 can be adjusted efficiently, thereby improving the efficiency of the surgeon in adjusting the interventional instrument or the handle 200 on the track 21 before or during the operation, and further shortening the operation time and improving the safety of the operation.

[0056] Please see Figure 6-11 As shown, the support module 10 includes a first lifting member 11 and a second lifting member 12. The first lifting member 11 is connected to the drive unit 31, and the second lifting member 12 is connected to the braking unit 32. The first lifting member 11 and the second lifting member 12 are respectively connected to the interventional device or to the handle 200 of the interventional device, so as to jointly support the interventional device or jointly support the handle 200 of the interventional device.

[0057] The track 21 includes a first segment 211 and a second segment 212 connected to each other. The drive unit 31 includes a first slider 311 and a drive member 312. The first slider 311 is slidably sleeved on the first segment 211 so that the first slider 311 and the first segment 211 mutually limit each other. The drive member 312 is connected between the first segment 211 and the first slider 311, so that the first slider 311 can move synchronously on the first segment 211 with the drive member 312 in cooperation with the drive member 312.

[0058] The first lifting member 11 is disposed on the first sliding member 311 and moves synchronously with the first sliding member 311 and the driving member 312 relative to the first segment 211.

[0059] The braking unit 32 includes a second sliding member 321 and a braking member 322. The second lifting member 12 is disposed on the second sliding member 321. The second sliding member 321 is slidably sleeved on the second segment 212 so that the second sliding member 321 and the second segment 212 mutually limit each other. When the braking unit 32 is in the released state, the second sliding member 321 can move synchronously with the first sliding member 311, the first lifting member 11, the second lifting member 12, the interventional device, or the handle 200 under the drive of the driving member 312.

[0060] The braking element 322 is movably connected to the second sliding element 321. When the braking unit 32 is in the braking state, the braking element 322 abuts against the second segment 212 to restrict the movement of the second sliding element 321 relative to the second segment 212. This allows the braking unit 32 and the driving unit 31 to remain relatively stationary with respect to the track 21 under the combined cooperation of the first lifting element 11, the second lifting element 12, and the interventional device or the handle 200. This allows the interventional device or the handle 200 to be accurately positioned on the track 21.

[0061] When the braking unit 32 is in the released state, the braking element 322 is separated from the second segment 212. At this time, the driving element 312 drives the first sliding element 311 to move, which can drive the first lifting element 11, the interventional device or the handle 200, as well as the second lifting element 12, the second sliding element 321 and the braking element 322 to move synchronously relative to the track 21, thereby adjusting the position of the interventional device or the handle 200 on the track 21.

[0062] Please see Figure 6 , 8 As shown in Figures 10-11, in the embodiments of this application, the first segment 211 is a rack, and at least one side of the second segment 212 is a plane. The driving member 312 is a gear. The driving unit 31 further includes an adjusting member 313, which is rotatably connected to the first sliding member 311. The gear is connected to the adjusting member 313 and meshes with the rack. Therefore, by rotating the adjusting member 313, the gear can be driven to rotate synchronously to change the position of the gear on the rack, thereby changing the position of the first sliding member 311 on the first segment 211, and thus changing the position of the first lifting member 11, the interventional instrument or the handle 200, the second lifting member 12, the second sliding member 321, and the braking member 322 on the track 21.

[0063] The braking unit 32 further includes a roller 323, which is rotatably connected to the second sliding member 321 and closely attached to the plane of the second segment 212. By setting the roller 323, the mutual positioning between the second sliding member 321 and the second segment 212 can be made more stable, and the movement of the second sliding member 321 relative to the second segment 212 can be made smoother, thereby improving the stability and efficiency of the movement of the adjustment module and the support module 10 relative to the track 21, and effectively reducing friction noise during the movement process.

[0064] When the braking unit 32 is in the braking state, the braking member 322 abuts against the second section 212 so that the roller 323 remains stationary relative to the plane and the gear remains stationary relative to the rack. When the braking unit 32 is in the release state, the braking member 322 separates from the second section 212, and the adjusting member 313 drives the gear to move relative to the rack under the action of external force, so as to drive the first sliding member 311, the supporting module 10, the braking unit 32, and the interventional device or the handle 200 of the interventional device to move synchronously relative to the track 21.

[0065] In the embodiments of this application, the first segment 211 is a screw, and at least one side of the second segment 212 is a plane; the driving member 312 is a nut, which is threadedly connected to the screw and rotatably connected to the first sliding member 311. Therefore, the nut rotates threadedly relative to the screw under the drive of an external force, thereby changing its position on the screw. Through the rotatable connection between the nut and the first sliding member 311, the first sliding member 311 can move synchronously with the nut along the extension direction of the track 21.

[0066] The braking unit 32 further includes a roller 323, which is rotatably connected to the second sliding member 321 and closely attached to the plane of the second segment 212. By setting the roller 323, the mutual positioning between the second sliding member 321 and the second segment 212 can be made more stable, and the movement of the second sliding member 321 relative to the second segment 212 can be made smoother, thereby improving the stability and efficiency of the movement of the adjustment module and the support module 10 relative to the track 21, and effectively reducing friction noise during the movement process.

[0067] When the braking unit 32 is in the braking state, the braking member 322 abuts against the second section 212 so that the roller 323 remains stationary relative to the plane and the nut remains stationary relative to the screw. When the braking unit 32 is in the release state, the braking member 322 separates from the second section 212, and the nut moves relative to the screw under the action of an external force to drive the first sliding member 311, the support module 10, the braking unit 32, and the interventional device or the handle 200 of the interventional device to move synchronously relative to the track 21.

[0068] Please see Figure 6-7As shown, the driving unit 31 further includes a plurality of first elastic abutment members 314. The plurality of first elastic abutment members 314 are respectively connected to the first sliding member 311 and elastically abut against the side of the first segment 211 opposite to the driving member 312.

[0069] The first elastic support member 314 may be a ball-head plunger or other structural member that can be connected to the first sliding member 311 and elastically support the side of the first segment 211 away from the gear, and is not limited here.

[0070] Each of the first elastic abutment members 314 has an external thread, and the first sliding member 311 has a corresponding first threaded hole 3111 for each of the first elastic abutment members 314, so that each of the first elastic abutment members 314 is threadedly connected to the first sliding member 311. Therefore, when the side of the rack away from the gear is not flat enough, multiple first elastic abutment members 314 can adaptively abut the side of the rack away from the gear, thereby cooperating with the gear to make the first sliding member 311 stably sleeved on the rack. Therefore, the meshing between the gear and the rack can be more precise, thereby making the movement of the gear relative to the rack to adjust the position of the interventional device or the handle 200 more accurate.

[0071] In addition, by setting the first elastic support member 314, direct contact between the side of the rack away from the gear and the first sliding member 311 can be avoided. Therefore, the noise generated by friction during the movement of the first sliding member 311 relative to the rack can be reduced by the smaller contact area between the first elastic member and the rack compared to the rack and the first sliding member 311.

[0072] Furthermore, when the first elastic support member 314 is a ball-head plunger, during the movement of the first sliding member 311 relative to the rack, the hard ball head of the ball-head plunger supporting the rack can also rotate, thereby further improving the smoothness of the movement of the first sliding member 311 relative to the rack and further reducing friction noise.

[0073] Please see Figure 8-9 As shown, the braking unit 32 also includes a plurality of second elastic abutment members 324, which are respectively connected to the second sliding member 321 and elastically abut against the side of the second segment 212 opposite to the roller 323.

[0074] The second elastic support member 324 may be a ball-head plunger or other structural member that can be connected to the second sliding member 321 and elastically support the side of the second segment 212 away from the roller 323, and is not limited here.

[0075] Each of the second elastic abutment members 324 has an external thread, and the second sliding member 321 has a corresponding second threaded hole 3211 for each of the second elastic abutment members 324, so that each of the second elastic abutment members 324 is threadedly connected to the second sliding member 321. Therefore, when the side of the second segment 212 away from the roller 323 is not flat enough, multiple second elastic abutment members 324 can adaptively abut the side of the second segment 212 away from the roller 323, thereby cooperating with the roller 323 to make the second sliding member 321 stably fitted on the second segment 212. Therefore, the roller 323 and the second segment 212 can be more precisely fitted, so that the movement of the roller 323 relative to the second segment 212 to adjust the position of the interventional device or the handle 200 is more accurate.

[0076] In addition, by setting the second elastic support member 324, direct contact between the side of the second segment 212 away from the roller 323 and the second sliding member 321 can be avoided. Therefore, the noise generated by friction during the movement of the second sliding member 321 relative to the second segment 212 can be reduced by the smaller contact area between the second elastic member and the second segment 212 compared to the contact area between the second segment 212 and the second sliding member 321.

[0077] Furthermore, when the second elastic support member 324 is a ball-head plunger, during the movement of the second sliding member 321 relative to the second segment 212, the hard ball head of the ball-head plunger supporting the rack can also rotate, thereby further improving the smoothness of the movement of the second sliding member 321 relative to the second segment 212 and further reducing friction noise.

[0078] In the embodiments of this application, please refer to Figure 1-5 As shown, the gear and the roller 323 are located on the same side of the track 21. Therefore, the first rotation axis 3121 of the gear and the second rotation axis 3231 of the roller 323 are parallel to each other, and the first rotation axis 3121 and the second rotation axis 3231 are perpendicular to the extension direction of the track 21. This allows the gear and the roller 323 to remain stably connected to the track 21 under the action of the first elastic support member 314 and the second elastic support member 324, respectively, thereby achieving stable support and precise position adjustment of the interventional device or the handle 200.

[0079] The first lifting member 11 and the second lifting member 12 are located on the same side of the track 21, so that the force exerted by the first lifting member 11 on the first sliding member 311 and the force exerted by the second lifting member 12 on the second sliding member 321 are in the same direction, thereby ensuring stable support for the interventional device or the handle 200.

[0080] Please see Figure 6-7 As shown, the first sliding member 311 has a first sliding hole 3112 and a first receiving hole 3113. The first receiving hole 3113 communicates with the first sliding hole 3112, which extends through the first sliding member 311 along the extending direction of the track 21. The first threaded hole 3111 communicates with the first sliding hole 3112 and is opposite to the first receiving hole 3113. The gear is rotatably disposed in the first receiving hole 3113 and meshes with the first segment 211 of the track 21 that passes through the first sliding hole 3112.

[0081] By providing the first receiving hole 3113 and the first sliding hole 3112, the first sliding member 311 can be restricted from deviating from the rack by the first sliding hole 3112, and the gear can be restricted from deviating from the rack by the first receiving hole 3113, so that the gear is always stably meshed with the rack.

[0082] Please see Figure 8-9 As shown, the second sliding member 321 has a second sliding hole 3212 and a second receiving hole 3213. The second receiving hole 3213 communicates with the second sliding hole 3212. The second sliding hole 3212 extends through the second sliding member 321 along the extension direction of the track 21. The second threaded hole 3211 communicates with the second sliding hole 3212 and is opposite to the second receiving hole 3213.

[0089] Please see Figure 10-12 As shown, the support module 20 also includes a base plate 22 and a support plate 23. The support plate 23 is connected between the base plate 22 and the track 21 and is used to support the track 21 at an angle above the base plate 22.

[0090] The support plate 23 includes a first connecting surface 231 and a second connecting surface 232. The first connecting surface 231 is in contact with the base plate 22, and the second connecting surface 232 is in contact with the track 21. The second connecting surface 232 is inclined relative to the base plate 22 and gradually approaches the base plate 22 along the direction from the drive unit 31 to the braking unit 32, so that the track 21 is inclinedly disposed on the support plate 23.

[0091] In embodiments of this application, the support plate 23 has a plurality of third threaded holes 233 on the first connecting surface 231, and the plurality of third threaded holes 233 are spaced apart along the extension direction of the track 21. The base plate 22 has a third countersunk through hole 221 corresponding to each of the third threaded holes 233. The support plate 23 also has a plurality of fourth threaded holes 234 on the second connecting surface 232, and the plurality of fourth threaded holes 234 are spaced apart along the extension direction of the track 21. The track 21 has a fourth countersunk through hole 2131 corresponding to each of the fourth threaded holes 234.

[0092] The support module 20 further includes a first countersunk fastener 24 and a second countersunk fastener 25. The first countersunk fasteners 24 are respectively inserted through a third countersunk through hole 221 and threadedly connected to a corresponding third threaded hole 233, so that the base plate 22 and the support plate 23 are detachably fixedly connected. The second countersunk fasteners 25 are respectively inserted through a fourth countersunk through hole 2131 and threadedly connected to a corresponding fourth threaded hole 234, so that the track 21 and the support plate 23 are detachably fixedly connected.

[0093] In embodiments of this application, the support plate 23 may also be connected to the track 21 and the base plate 22 by welding. No limitation is made here.

[0094] By connecting the base plate 22 to the track 21 with the support plate 23, the overall structural stability and assembly efficiency of the support module 20 can be effectively improved.

[0095] The base plate 22 is approximately I-shaped along the direction of the track 21, so that the base plate 22 can stably support the track 21, thereby supporting the support module 10 and the adjustment module through the track 21.

[0096] Please see Figure 11 As shown, the track 21 further includes a third segment 213, which is connected between the first segment 211 and the second segment 212. The support plate 23 is connected between the third segment 213 and the base plate 22, thereby preventing the first sliding member 311 or the third sliding member from passing through the third segment 213, and limiting the first sliding member 311 or the third sliding member by the support plate 23 connected to the third segment 213.

[0097] Please see Figure 1-5As shown, the support device 100 further includes a connection module 40. The connection module 40 includes at least one connector 41, which is parallel to the extension direction of the track 21. Both ends of the connector 41 are connected to the drive unit 31 and the braking unit 32, respectively, so that the drive unit 31 and the braking unit 32 remain relatively stationary on the track 21. This allows the drive unit 31 to be more accurately positioned on the track 21 by the braking unit 32 under the action of the connector 41, thereby enabling the interventional instrument or the handle 200 to be more accurately positioned on the track 21.

[0098] In the embodiments of this application, the connecting module 40 may include two connecting members 41, both of which are rigid connecting rods. The two connecting rods are parallel to the track 21 along the extension direction of the track 21 and are located on both sides of the track 21. The two connecting rods are detachably fixedly connected to the first sliding member 311 and the second sliding member 321, respectively. This allows the driving unit 31 to be synchronously stationary on the track 21 in a symmetrical and stable manner relative to the track 21 when the braking unit 32 is in the braking state. In the case where the braking unit 32 is in the release state, the driving unit 31 can directly and quickly drive the braking unit 32 to move synchronously relative to the track 21 through the two connecting rods. This further enhances the ability of the first sliding member 311 and the second sliding member 321 to maintain stable synchronous movement or stable synchronous stationary relative to the track 21, based on the first lifting member 11, the second lifting member 12, and the interventional device or the handle 200.

[0099] Please refer to the following: Figure 6-9As shown, the first sliding member 311 has two first connecting holes 3116, and a fifth threaded hole 3117 corresponding to each of the first connecting holes 3116. Each fifth threaded hole 3117 is connected to the corresponding first connecting hole 3116. The second sliding member 321 has two second connecting holes 3216, and a sixth threaded hole 3217 corresponding to each of the second connecting holes 3216. Each sixth threaded hole 3217 is connected to the corresponding second connecting hole 3216. The connecting module 40 also includes two third elastic abutting members 42 and a fourth elastic abutting member 43. Each third elastic abutting member 42 is threaded into the fifth threaded hole 3117 and elastically abuts against the first end of the connecting rod inserted into the corresponding first connecting hole 3116. Each fourth elastic abutting member 43 is threaded into the sixth threaded hole 3217 and elastically abuts against the second end of the connecting rod inserted into the corresponding second connecting hole 3216.

[0100] The first end of the connecting rod can be interference-fitted into the first connecting hole 3116, and the second end of the connecting rod can be interference-fitted into the second connecting hole 3216.

[0101] Please see Figure 5 , 13 As shown in Figure 14, the support module 10 further includes a support assembly 13. The support assembly 13 includes a support member 131. The two ends of the support member 131 along the extension direction of the track 21 are rotatably disposed on the first retrieval member 11 and the second retrieval member 12, respectively, and are used to support the interventional device or the handle 200 of the interventional device. This allows the support member 131 to rotate synchronously with the supported interventional device or the handle 200 relative to the first retrieval member 11 and the second retrieval member 12 to adjust the position of the handle 200. This facilitates the rotational adjustment of the position of the catheter or sheath passing through the handle 200 on the support device 100, so that the operator can control the distal structure of the interventional device inserted in the catheter or sheath to perform surgery on the patient's lesion at a suitable angle / position.

[0102] The first lifting member 11 has a first supporting groove 111, which is U-shaped. The second lifting member 12 has a second supporting groove 121, which is U-shaped. The first and second lifting grooves are respectively used to lift the opposite ends of the supporting member 131 along the extension direction of the track 21, and to allow the supporting member 131 to rotate.

[0103] The support member 131 includes a support body 1311, a first rotating part 1312, and a second rotating part 1313. The first rotating part 1312 and the second rotating part 1313 are respectively connected to opposite ends of the support body 1311 along the extension direction of the track 21. The first rotating part 1312 is rotatably disposed in the first support groove 111, and the second rotating part 1313 is rotatably disposed in the second support groove 121. This allows the support member 131 to be rotated 360 degrees relative to the first lifting member 11 and the second lifting member 12, thereby increasing the range of rotational adjustment of the interventional instrument or the handle 200 to meet the operator's adjustment of the catheter or the sheath to any rotational angle. This can effectively reduce the difficulty of surgery, improve surgical efficiency, and reduce surgical risks.

[0104] In the embodiments of this application, the first rotating part 1312 and the second rotating part 1313 are integral with the supporting body 1311, thereby simplifying the assembly steps of the supporting part 131.

[0105] In the embodiments of this application, please refer to Figure 13-14 As shown, one of the first rotating part 1312 and the second rotating part 1313 is detachably connected to the supporting body 1311, and the other of the first rotating part 1312 and the second rotating part 1313 is an integral structure with the supporting body 1311.

[0106] In embodiments of this application, the first rotating part 1312 and the second rotating part 1313 are detachably connected to the supporting body 1311. The supporting assembly 13 further includes a first fixing connector 132, a second fixing connector 133, a first positioning member 134, and a second positioning member 135. At least one first positioning member 134 is used to position the first rotating part 1312 relative to the supporting body 1311; at least one first fixing connector 132 is used to detachably fix the positioned first rotating part 1312 to the supporting body 1311; at least one second positioning member 135 is used to position the second rotating part 1313 relative to the supporting body 1311; and at least one second fixing connector 133 is used to detachably fix the positioned second rotating part 1313 to the supporting body 1311.

[0107] By setting the first positioning member 134, the first rotating part 1312 and the supporting body 1311 can be precisely connected, and by setting the second positioning member 135, the second rotating part 1313 and the supporting body 1311 can be precisely connected, so that the first rotating part 1312 and the second rotating part 1313 can be on the same rotation axis 14, thereby allowing the supporting member 131 to rotate along the rotation axis 14.

[0108] Please see Figure 13-14 As shown, the support module 10 further includes a first fixing member 15 and a second fixing member 16. The first lifting member 11 includes a first supporting part 112 and two first limiting parts 113. The two first limiting parts 113 are respectively connected to the first supporting part 112 and together with the first supporting part 112, they form the first supporting groove 111. At least one of the first limiting parts 113 is threadedly connected to a first fixing member 15.

[0109] The second support member 12 includes a second support portion 122 and two second limiting portions 123. The two second limiting portions 123 are respectively connected to the second support portion 122 and together with the second support portion 122, they form the second support groove 121. At least one of the second limiting portions 123 is threadedly connected to a second fixing member 16.

[0110] When the interventional device or its handle 200 needs to be rotated, each of the first fixing members 15 separates from the first rotating part 1312, and each of the second fixing members 16 separates from the second rotating part 1313. At least one of the support member 131, the interventional device, and the handle 200 rotates relative to the first lifting member 11 and the second lifting member 12 under the action of an external force, thereby adjusting the angle of the interventional device or the handle 200. When the interventional device or its handle 200 is rotated to a preset angle, the first fixing members 15 are rotated so that each of the first fixing members 15 abuts against the first rotating part 1312, and the second fixing members 16 are rotated so that each of the second fixing members 16 abuts against the second rotating part 1313, thereby restricting the rotation of the support member 131 relative to the first lifting member 11 and the second lifting member 12, thereby rotating the interventional device or the handle 200 to a specified angle.

[0111] By setting the support 131 to rotate synchronously with the interventional device or the handle 200, the requirements of the support module 10 on the external structure of the interventional device or the handle 200 can be reduced, and the adjustment efficiency of rotation can be improved.

[0112] Please see Figure 13-14 As shown, the first rotating part 1312 has a first limiting groove 13121. When the first rotating part 1312 is rotatably limited within the first supporting groove 111, the first supporting part 112 and the two first limiting parts 113 are respectively limited within the first limiting groove 13121. Therefore, the first supporting part 112 and the first rotating part 1312 can limit each other, thereby improving the stability of the rotation of the first rotating part 1312 relative to the first supporting part 112.

[0113] The second rotating part 1313 has a second limiting groove 13131. When the second rotating part 1313 is rotatably limited within the second supporting groove 121, the second supporting part 122 and the two second limiting parts 123 are respectively limited within the second limiting groove 13131. Therefore, the second supporting part 122 and the second rotating part 1313 can limit each other, thereby improving the stability of the rotation of the second rotating part 1313 relative to the second supporting part 122.

[0114] The supporting body 1311 includes a supporting plate portion 13111 and a plurality of limiting plate portions 13112. The plurality of limiting plate portions 13112 are spaced apart on the side of the supporting plate portion 13111 away from the track 21, and together with the supporting plate portion 13111, they form a mounting groove 13113. The mounting groove 13113 is used to install the interventional device or the handle 200 of the interventional device, so as to support the interventional device or the handle 200.

[0115] Please refer to Figure 13-14 As shown, the support assembly 13 further includes a third fixing member 136, which is threadedly connected to at least one of the limiting plate portions 13112 located on the first side of the support plate portion 13111. When the interventional device or its handle 200 is disposed within the mounting groove 13113 and abuts against the limiting plate portion 13112 located on the second side of the support plate portion 13111, the third fixing member 136 is rotated to bring it closer to the interventional device or handle 200 and abut against the surface of the interventional device or handle 200 near the first side, thereby fixing the interventional device or handle 200 to the support body 1311. The first side and the second side are opposite sides of the support plate portion 13111 perpendicular to the extending direction of the track 21.

[0116] By providing the third fixing member 136 on the limiting plate portion 13112 on the first side of the support plate portion 13111, and positioning the interventional device or the handle 200 with the limiting plate portion 13112 on the second side as a reference, it can be ensured that the interventional device or the handle 200 is always positioned at the same location on the support member 131. Even interventional devices or handles 200 with different external dimensions can be positioned at the same location on the support member 131 with the limiting plate portion 1312 on the second side as a reference and the third fixing member 136, thus accommodating interventional devices or handles 200 with different external dimensions.

[0117] In the embodiments of this application, please refer to Figure 13-14 As shown, the third fixing member 136 can be a hand-tight fixing member, so that the operator can quickly and easily twist the third fixing member 136 by hand, thereby causing the third fixing member 136 to abut against the interventional device or the handle 200, or to move away from the interventional device or the handle 200.

[0118] In embodiments of this application, the third fixing member 136 may also elastically abut against the surface of the interventional device or elastically abut against the surface of the handle 200. The third fixing member 136 may be a ball plunger with a hand-tightening structure, so that the third fixing member 136 can be turned by hand without the aid of tools, and can also adaptively and elastically abut against the interventional device or the handle 200.

[0119] In an embodiment of this application, the support assembly 13 further includes a fourth fixing member. At least one of the limiting plate portions 13112 located on the third side of the support plate portion 13111 is threadedly connected to the fourth fixing member. When the interventional instrument or the handle 200 is disposed within the mounting groove 13113 and abuts against the limiting plate portion 13112 located on the fourth side of the support plate portion 13111, the fourth fixing member is rotated to bring it closer to the interventional instrument or the handle 200 and abut against the surface of the interventional instrument or the handle 200 near the third side, thereby fixing the interventional instrument or the handle 200 to the support body 1311. The third side and the fourth side are opposite sides of the support plate portion 13111 extending along the track 21.

[0120] By providing the fourth fixing member on the limiting plate portion 13112 on the third side of the support plate portion 13111, and positioning the interventional device or the handle 200 with the limiting plate portion 13112 on the fourth side as a reference, it can be ensured that the interventional device or the handle 200 is always positioned at the same location on the support member 131. Even interventional devices or handles 200 with different external dimensions can be positioned at the same location on the support member 131 with the limiting plate portion 13112 on the fourth side as a reference and by the fourth fixing member, thus accommodating interventional devices or handles 200 with different external dimensions.

[0121] In embodiments of this application, the fourth fixing member may be a hand-tightening fixing member, so that the operator can quickly and easily twist the fourth fixing member by hand, thereby causing the fourth fixing member to abut against the interventional device or the handle 200, or to move away from the interventional device or the handle 200.

[0122] In embodiments of this application, the fourth fixing member may also be elastically abutting against the surface of the interventional device or elastically abutting against the surface of the handle 200. The fourth fixing member may be a ball plunger with a hand-tightening structure, so that the fourth fixing member can be turned by hand without the aid of tools, and can also adaptively and elastically abut against the interventional device or the handle 200.

[0123] In the embodiments of this application, please refer to Figure 13-14 As shown, the limiting plate portion 13112 and the supporting plate portion 13111 can be an integral structure or a separate structure, which is not limited here. Wherein, if the limiting plate portion 13112 and the supporting plate portion 13111 are separate structures, different limiting plate portions 13112 and / or supporting plate portions 13111 can be replaced according to the different external dimensions of the interventional device or the handle 200 to accommodate interventional devices or the handle 200 of more external dimensions; if the limiting plate portion 13112 and the supporting plate portion 13111 are an integral structure, assembly can be simplified, and the structural accuracy, structural strength, and stability of the supporting member 131 can be ensured.

[0124] On the other hand, please see Figure 1-4 As shown, this application also provides an interventional medical system, which includes the aforementioned support device 100. Therefore, the interventional medical system has all the beneficial effects of the support device 100, which will not be elaborated here.

[0125] The interventional medical system also includes an interventional device, the interventional device or the handle 200 of the interventional device being detachably mounted on the support module 10, and the position and rotation angle adjustment on the track 21 being realized through the support device 100.

[0126] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0127] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0128] The above are merely preferred embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
