Description

Technical Field

[0001] This invention relates to a device in the field of medical robots, and more particularly to an interventional surgical assistive clamping device. Background Technology

[0002] Interventional therapy is a minimally invasive treatment that utilizes modern high-tech methods. Under the guidance of medical imaging equipment, specialized catheters, guidewires, and other precision instruments are introduced into the human body to diagnose and treat internal diseases locally.

[0003] When catheters and guidewires are driven and delivered on the drive device, if the distance between the two drive devices is far, it is necessary to support the catheters and guidewires between the two drive devices to prevent the catheters and guidewires from deforming and affecting normal delivery. However, the existing clamping devices for supporting catheters and guidewires have a complex structure and are not easy to install, which affects the surgeon's efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a novel interventional surgical assist clamping device to address the shortcomings of existing technologies.

[0005] An interventional surgical auxiliary clamping device is used to clamp a slender medical device. It includes a fixed base, a clamping assembly mounted on the fixed base, and a cover plate movably mounted on the fixed base and linked with the clamping assembly. When the cover plate is closed on the fixed base, the clamping assembly clamps the slender medical device. When the cover plate is opened, the clamping assembly is driven to release the slender medical device.

[0006] Furthermore, the cover plate is provided with a first linkage piece connected to the clamping assembly, the cover plate is rotatably fixed on the fixed base, and the rotation axis of the cover plate is not coaxial with the rotation axis of the first linkage piece.

[0007] Furthermore, the clamping assembly includes a movable plate connected to the first linkage plate, a driven wheel assembly mounted on the movable plate, a driving wheel assembly abutting against the driven wheel assembly, and an elastic return member for pushing the movable plate back into position. During the opening process of the cover plate, the first linkage plate on the cover plate drives the driven wheel assembly to move outward and separate from the driving wheel assembly.

[0008] Furthermore, the first linkage plate is provided with a protrusion that is not coaxial with the rotation axis of the cover plate, and the movable plate is provided with a second linkage plate. The second linkage plate is provided with a stop groove that cooperates with the protrusion. Under the action of the elastic return member, the stop groove abuts against the protrusion.

[0009] Furthermore, the cover plate is provided with support legs, and the support legs of the cover plate are pivotally connected to the fixed seat by a locking pin.

[0010] Furthermore, the axis of the protruding post and the axis of the locking pin are not on the same axis.

[0011] Furthermore, the mounting base is provided with several support plates for supporting slender medical devices.

[0012] Furthermore, an installation space is formed between two adjacent support plates, and each installation space accommodates one drive roller of the drive wheel assembly.

[0013] Furthermore, the support plate has a support groove for placing slender medical devices.

[0014] Furthermore, the cover plate is also provided with several cards, which cooperate with the support groove of the support plate to restrict slender medical devices.

[0015] In summary, the interventional surgical auxiliary clamping device of the present invention links the cover plate with the clamping assembly. When the cover plate flips outward, it simultaneously drives the driven wheel assembly and the driving wheel assembly to separate. Doctors can quickly install slender medical devices between the driving wheel assembly and the driven wheel assembly, achieving rapid installation and effectively improving the surgeon's efficiency. It is highly practical and has significant potential for widespread application. Attached Figure Description

The terms "upper" and "upper part" refer to the direction away from gravity, while the terms "bottom," "lower," and "lower part" refer to the direction of gravity. "Inner side" refers to the position direction close to the elongated medical device 10, "outer side" refers to the position direction away from the elongated medical device 10, "front" refers to the side facing the user, and "rear" refers to the side away from the user.

[0022] like Figures 1 to 3 As shown, the present invention provides an interventional surgery auxiliary clamping device for clamping and supporting slender medical devices (such as catheters and guidewires) 10. The interventional surgery auxiliary clamping device includes a fixed base 20, a clamping assembly 30 mounted on the fixed base 20, and a cover plate 40 movably mounted on the fixed base 20 and linked with the clamping assembly 30. The cover plate 40 can be opened from the fixed base 10 or closed on the fixed base 20.

[0023] The fixing base 20 has a limiting part 21 at its distal end. The limiting part 21 has a mounting groove 211 corresponding to the shape of a hemostatic valve (such as a T valve or Y valve) for placing the hemostatic valve. The fixing base 20 has several support plates 22 distributed along the delivery path of the elongated medical device 10 near its distal end. The support plates 22 have V-shaped support grooves 221 with a narrow inner edge and a wide outer edge, facing the mounting grooves 211, for placing the elongated medical device. An installation space 222 is formed between two adjacent support plates 22. The fixing base 20 has two functional plates 23 arranged opposite each other at its rear side, facing the support plates 22. The fixing base 20 also has a sliding groove 24 between the two functional plates 23, facing the functional plates 23. The bottom of the sliding groove 24 has a first receiving groove 25. The functional plates 23 have through holes 231, and the through holes 231 on the two functional plates 23 are arranged opposite each other. The fixed base 20 is also provided with two opposing adjustment plates 26 on one side of the slide groove 24. The adjustment plates 26 are provided with adjustment holes 261, and the adjustment holes 261 on the two adjustment plates 26 are also arranged opposite each other. The function plate 23 and the slide groove 24 are located between the two adjustment plates 26.

[0024] The clamping assembly 30 includes a guide rod 31, a movable plate 32 slidably mounted on the guide rod 31, a driven wheel assembly 33 rotatably mounted on the movable plate 32, a driving wheel assembly 34 opposite to the driven wheel assembly 33 and rotatably mounted on the fixed base 20, an elastic return member 37 for pushing the movable plate 32 back into position, and a gear assembly 36 that rotates synchronously with the driving wheel assembly 34 and meshes with the guide rail. The driving wheel assembly 34 and the driven wheel assembly 33 are respectively located on the front and rear sides of the delivery path of the slender medical device 10. The driving wheel assembly 34 includes several driving wheels, which are respectively arranged in different installation spaces 222 and separated by the support plate 22. In this embodiment, the fixed base 20 is equipped with a connecting shaft 35. One end of the connecting shaft 35 extends into the mounting space 222, and the other end extends from the bottom of the fixed base 20 to fix the gears of the gear set 36, thereby fixing the driving gear set 34 on the connecting shaft 35. The movable plate 32 is provided with a support rod 324, and the driven gear set 33 is mounted on the support rod 324 through a bearing. The movable plate 32 is disposed in the slide groove 24, and the guide rod 31 passes through the bottom of the movable plate 32 and is respectively placed in the two first receiving grooves 25. The two ends of the guide rod 31 are respectively installed in the through holes 231 on the two functional plates 23. In this embodiment, the elastic return member 37 is a return spring. Hereinafter, the return spring refers to the elastic return member 37.

[0025] The bottom of the movable plate 32 is provided with a second receiving groove 321 extending inward. The return spring is arranged in the space enclosed by the first receiving groove 25 and the second receiving groove 321. One end of the return spring abuts against the inner wall of the space enclosed by the first receiving groove 25 and the second receiving groove 321, that is, the bottom of the movable plate 32, and the other end of the return spring abuts against the outer functional plate 23. When the movable plate 32 is pushed outward, the movable plate 32 moves outward, and the return spring further contracts elastically. The movable plate 32 drives the driven wheel assembly 33 to move outward synchronously, thereby forming a gap between the driving wheel assembly 34 and the driven wheel assembly 33, which is directly opposite the V-shaped support groove 221 of the support plate 22. The slender medical device 10 is placed in the V-shaped support groove 221 between the driving wheel assembly 34 and the driven wheel assembly 33. Then the movable plate 32 is released, and the return spring squeezes the movable plate 32 and the driven wheel assembly 33 on the movable plate 32, thereby clamping the slender medical device 10 between the driven wheel assembly 33 and the driving wheel assembly 34.

[0026] The cover plate 40 has a foot 41 at its near end and a foot 41 at its far end. The two feet 41 of the cover plate 40 are pivotally connected to the adjustment holes 261 of the two adjustment plates 26 by a latch 411. The cover plate 40 can rotate on the fixed base 20 to flip open to the rear or close on the fixed base 20. When the cover plate 40 is closed on the fixed base 20, the cover plate 40 simultaneously limits the position of the slender medical device 10.

[0027] To ensure a more secure fit between the cover plate 40 and the fixing base 20, the cover plate 40 and the fixing base 20 are respectively provided with a first fixing block 71 and a second fixing block 72. In this embodiment, one of the first fixing block 71 and the second fixing block 72 is a magnet, and the other is a magnet or an iron block. Through the attraction force of the first fixing block 71 and the second fixing block 72, the cover plate 40 is securely placed on the fixing base 20. It can be understood that, in addition to the first fixing block 71 and the second fixing block 72 using a magnet-magnet / iron method for auxiliary fixation, in other embodiments, the first fixing block 71 and the second fixing block 72 can also be fixed using similar buckles, threaded locking, or other detachable structures.

[0028] The cover plate 40 is also provided with a number of cards 42 and a first linkage piece 43. The cards 42 and the support plate 22 are offset from each other along the direction in which the cover plate 40 covers the fixed seat 20. The cards 42 cooperate with the support groove 221 of the support plate 22 to limit the slender medical device 10 from both the top and bottom directions.

[0029] The first linkage plate 43 has a protruding post 431 at its end. The axis of the protruding post 431 is not on the same axis as the axis of the locking pin 411, so that when the cover plate 40 is flipped open, the protruding post 431 rotates around the axis of the locking pin 411 and moves outward at the same time, instead of just rotating in place around its own axis. The movable plate 32 also has a protruding second linkage plate 322, the extension direction of which is consistent with the installation direction of the return spring. The inner side of the second linkage plate 322 has a stop groove 323 that cooperates with the protruding post 431. Under the action of the return spring, the stop groove 323 abuts against the protruding post 431 from the outside.

[0030] When installing the slender medical device 10, the cover plate 40 is flipped outward. During the flipping process, the protrusion 431 on the cover plate 40 pushes the second linkage plate 322 of the movable plate 32 outward, thereby causing the driven wheel assembly 33 connected to the movable plate 32 to move outward, separating the driven wheel assembly 33 from the driving wheel assembly 34. The slender medical device 10 is placed between the driven wheel assembly 33 and the driving wheel assembly 34 and supported by the support groove 221 of the support plate 22. The cover plate 40 is then closed, and at the same time, the protrusion 431 moves inward. Under the action of the return spring, the return spring pushes the movable plate 32 to move inward, and the stop groove 323 of the second linkage plate 322 moves inward with the protrusion 431, thereby bringing the driving wheel assembly 34 and the driven wheel assembly 33 closer together and clamping the slender medical device 10. The external drive mechanism can be connected to the drive wheel assembly 34 through the gear set 36 to drive the drive wheel assembly 34 to rotate. During this movement, the drive wheel assembly 34 and the driven wheel assembly 33 cooperate to deliver the slender medical device 10.

[0031] In summary, the interventional surgical auxiliary clamping device of the present invention links the cover plate 40 with the clamping assembly 30. When the cover plate 40 flips outward, it simultaneously drives the driven wheel assembly 33 and the driving wheel assembly 34 of the clamping assembly 30 to separate. The doctor can quickly install the slender medical device 10 between the driving wheel assembly 34 and the driven wheel assembly 33, achieving rapid installation, effectively improving the doctor's surgical efficiency, and is highly practical and has great potential for promotion.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the scope of protection of the invention. Therefore, the scope of protection of the invention patent should be determined by the appended claims.
