Detailed Implementation

[0019] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0020] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] This application provides an auxiliary support device for an interventional delivery device. This auxiliary support device can drive the handle 7 of the interventional delivery device to move as a whole. At the same time, it can also make one of the split handles 7 move in correspondence with the other handle 7, thereby improving the convenience of operation and increasing the success rate of surgery.

[0022] like Figure 1 As shown, the auxiliary support device includes a first support component 4 supporting the handle 7 and a second support component 100 connected to the first support component 4. The second support component 100 can drive the first support component 4 to move as a whole, thereby causing the handle 7 to move as a whole. The first support component 4 includes a fixed claw 8 supporting a part of the handle 7 and a movable claw 6 supporting the other part of the handle 7. The movable claw 6 can move relative to the fixed claw 8, so that the handle 7 supported by the movable claw 6 can move relative to the handle 7 supported by the fixed claw 8, meeting usage requirements and improving product adaptability. The second support component 100 includes a bracket 1 and a first threaded drive component 3. The first threaded drive component 3 is connected to the bracket 1, and the bracket 1 is used to support the first support component 4. The first threaded drive component 3 is threadedly driven to the first support component 4, and can drive the first support component 4 to move as a whole. The first threaded drive component 3 drives the movable claw 6 to move by a thread. Compared with the gear and rack drive method, there is no need to set up an additional locking mechanism. The threaded drive method has self-locking property, reducing the production cost of the auxiliary support device.

[0023] like Figure 2 and 3 As shown, in one embodiment, the bracket 1 is provided with a first receiving groove 11, and the first support assembly 4 includes a connecting frame 2. The connecting frame 2 includes a horizontal bar and a vertical bar. The two ends of the horizontal bar are respectively connected to a movable claw 6 and a fixed claw 8. One end of the vertical bar is inserted into the first receiving groove 11, and the other end is connected to the horizontal bar. The first threaded drive member 3 passes through the first receiving groove 11 along the axial direction of the first receiving groove 11 and is threadedly driven connected to the vertical bar of the connecting frame 2, which can drive the connecting frame 2 to move as a whole. At the same time, when the connecting frame 2 needs to stop moving, the first threaded drive member 3 can be stopped from rotating, without the need to set up an additional locking mechanism, thus reducing production costs.

[0024] Optionally, the peripheral wall of the first receiving groove 11 limits the connecting frame 2. When the first threaded drive 3 rotates and drives the connecting frame 2 to move, the connecting frame 2 moves along the axial direction of the first receiving groove 11, thereby driving the first support assembly 4 to move as a whole.

[0025] Optionally, the bracket 1 includes a columnar horizontal section and a vertical section connected to the horizontal section, wherein a first receiving groove 11 is formed on the horizontal section, and the vertical section is used to connect to the adjustment component.

[0026] Optionally, the first threaded drive 3 is not connected to the bracket 1. The first threaded drive 3 passes through the horizontal section of the bracket 1. That is, when the first threaded drive 3 rotates, its relative position with the bracket 1 remains unchanged, and when it rotates, it can drive the connecting frame 2 to move relative to the bracket 1.

[0027] like Figure 2 and 4 As shown, in one embodiment, the first threaded drive member 3 includes a first rod portion 311 with a drive thread; the auxiliary support device includes a clamping member 32 to prevent the first threaded drive member 3 from falling off. The first threaded drive member 3 passes through the bracket 1 along the axial direction of the first receiving groove 11, and the insertion end of the first threaded drive member 3 protrudes from the bracket 1. The clamping member 32 clamps the outer surface of the protruding portion of the first rod portion 311 and is in contact with one end of the bracket 1. Since the clamping member 32 is in contact with one end of the bracket 1, the axial direction of the first threaded drive member 3 is limited, thereby reducing the problem of the first threaded drive member 3 falling off from the first receiving groove 11.

[0028] Optionally, the length of the threaded section of the first rod 311 is adapted to the length of the first receiving groove 11, so that the rest of the first rod 311 is not threaded to the bracket 1, but the threaded section is threaded to the connecting frame 2. This ensures that when the first threaded drive 3 rotates, there is no relative displacement between the first threaded drive 3 and the bracket 1.

[0029] Optionally, the first rod portion 311 includes an insertion section located at the end, which is connected to a threaded section. The diameter of the insertion section is smaller than that of the threaded section. The insertion section has a groove for clamping by the clamping member 32. The first rod portion 311 passes through the bracket 1, and the grooved portion of the insertion section protrudes from the bracket 1. The clamping member 32 can be embedded in the groove of the first rod portion 311 to limit one end of the insertion section. Since the diameter of the threaded section is larger than that of the insertion section, the end face of the threaded section will limit the other end of the insertion section. The clamping member 32 cooperates with the threaded section to limit the first rod portion 311 in the axial direction.

[0030] Optionally, the first threaded drive 3 includes a knob and a first rod 311. The knob is fixedly connected to the first rod 311. The first rod 311 includes a threaded section and an insertion section. The vertical rod of the connecting frame 2 is limited by the peripheral wall of the first receiving groove 11. The knob rotates the first rod 311, so that the vertical rod can move along the first rod 311 and in the axial direction of the first receiving groove 11, thereby realizing that the first threaded drive 3 drives the first support assembly 4 to move relative to the bracket 1.

[0031] like Figure 2 As shown, in one embodiment, the connecting frame 2 includes a receiving portion 21 located at one end of the crossbar. The receiving portion 21 is provided with a second receiving groove parallel to the crossbar. The first support assembly 4 includes a slider 41 and a second threaded drive member 42. The slider 41 is disposed in the second receiving groove and connected to the movable claw 6. The second threaded drive member 42 is fixedly connected to the slider 41 and threadedly driven connected to the receiving portion 21, so that the second threaded drive member 42 can move relative to the receiving portion 21, thereby driving the movable claw 6 to move relative to the fixed claw 8. At the same time, the second receiving groove is parallel to the crossbar, so that when the movable claw 6 moves relative to the fixed claw 8, the handle 7 supported by the movable claw 6 and the handle 7 supported by the fixed claw 8 remain coaxial, improving the stability of operation.

[0032] Optionally, the second threaded drive member 42 is threadedly connected to the bottom wall of the receiving portion 21, so that the second threaded drive member 42 can generate relative displacement relative to the receiving portion 21.

[0033] Optionally, the receiving part 21 has a columnar structure, the slider 41 is also cylindrical, and the slider 41 is adapted to the second receiving groove.

[0034] Optionally, the crossbar is connected to the support part 22 and the receiving part 21 respectively. The connecting frame 2 also includes a vertical bar, which is connected to the crossbar. The vertical bar is used to insert into the first receiving groove 11 and is threadedly connected to the first threaded drive member 3.

[0035] like Figure 2 and 4As shown, in one embodiment, one end of the second threaded drive member 42 is provided with a positioning part 4211, and the end of the second threaded drive member 42 with the positioning part 4211 is inserted into the slider 41; the auxiliary support device includes a first fastener 12, which passes through the receiving part 21 and into the slider 41, abutting against the positioning part 4211; the slider 41 is provided with a hole 212 for the first fastener 12 to pass through, and the opposite end of the insertion end of the first fastener 12 does not protrude from the end face of the hole 212. The slider 41 and the second threaded drive member 42 are connected by the first fastener 12, and the second threaded drive member 42 can drive the slider 41 to move synchronously. At the same time, the opposite end of the insertion end of the first fastener 12 does not protrude from the end face of the hole 212, that is, the exposed end face of the first fastener 12 can be flush with the peripheral wall of the slider 41 or recessed in the peripheral wall of the groove, reducing the problem of interference between the first fastener 12 and the receiving part 21.

[0036] Optionally, the second threaded drive member 42 includes a second rod portion 421 and a knob connected to the second rod portion 421. A positioning portion 4211 is provided at the end of the second rod portion 421. The positioning portion 4211 can be a groove, or it can be a protrusion that can be inserted into the hole 212 of the slider 41. Alternatively, the positioning portion 4211 can be a through hole perpendicular to the second rod portion 421. The connection between the second rod portion 421 and the slider 41 is achieved by the first fastener 12 passing through the hole 212 and the through hole on the slider 41.

[0037] Optionally, an opening is also provided on the peripheral wall of the receiving part 21 to facilitate the passage of the first fastener 12. The opening on the peripheral wall of the receiving part 21 is coaxial with the hole 212 of the slider 41.

[0038] like Figure 2 As shown, in one embodiment, the peripheral wall of the receiving portion 21 is provided with a notch 211, which extends along the axial direction of the receiving portion 21; the slider 41 includes a protrusion 411, which is located in the notch 211. The notch 211 limits the protrusion 411, so that the slider 41 can move along the axial direction of the receiving groove, and at the same time, it also improves the stability of the slider 41.

[0039] like Figure 2 As shown, in one embodiment, the second threaded drive member 42 includes a second rod portion 421, the length of which does not exceed the length of the receiving portion 21, thereby reducing the problem of the slider 41 falling out of the second receiving groove. If the length of the second rod portion 421 is greater than the length of the receiving portion 21, when the second threaded drive member 42 rotates, it can drive the slider 41 to fall out of the second receiving groove, and the protrusion 411 also separates from the notch 211.

[0040] like Figure 2As shown, in one embodiment, the slider 41 is provided with a first slot 412, and the movable claw 6 is inserted into the first slot 412 and connected to the slider 41. The connecting frame 2 includes a support portion 22 spaced apart from the receiving portion 21. A second slot 221 is provided on the support portion 22, and the fixed claw 8 is inserted into the second slot 221 and connected to the support portion 22. By providing the second slot 221 on the support portion 22 and the first slot 412 on the slider 41, installation space is provided for both the fixed claw 8 and the movable claw 6.

[0041] Optionally, the slider 41 has a columnar structure, and the movable claw 6 is provided with an insertion rod. The insertion rod is adapted to the first slot 412 on the slider 41. The auxiliary support device also includes a second fastener, which is inserted by the end of the slider 41 away from the protrusion 411 and connected to the insertion rod.

[0042] Optionally, the second fastener can be inserted along the axial direction of the slider 41, or it can be inserted from other directions.

[0043] Optionally, the fixed claw 8 is provided with an insertion rod, which is adapted to the second slot 221. The auxiliary support device also includes a second fastener, which is inserted into one end of the support part 22 and connected to the insertion rod.

[0044] Optionally, the second fastener can be inserted along the axial direction of the support 22, or it can be inserted from other directions.

[0045] Optionally, the fixed claw 8 and the support part 22 can also be snapped together or glued together; similarly, the movable claw 6 and the slider 41 can also be snapped together or glued together.

[0046] Optionally, the length of the slider 41 is greater than the length of the receiving portion 21, the protrusion 411 is located at the first end of the slider 41, and the first slot 412 is located near the second end of the slider 41. The first end and the second end of the slider 41 refer to the two ends of the slider 41 in the axial direction, respectively. This allows the movable claw 6 to be located outside the receiving portion 21, reducing the interference of the movable claw 6 on the receiving portion 21 when the slider 41 slides.

[0047] Optionally, the support portion 22 is coaxial with the receiving portion 21 and is adapted to the split handle 7. In addition, it also allows the slider 41 to remain coaxial with the support portion 22 when sliding.

[0048] like Figure 1As shown, in one embodiment, the auxiliary support device includes an adjustment component, which includes multiple connecting arms 9, one of which is connected to the bracket 1. By setting the adjustment component, the overall height and fixed position of the auxiliary support device can be adjusted. At the same time, the direction of the auxiliary support device can also be adjusted so that the movable claw 6 and the fixed claw 8 can respectively support the handle 7, making it convenient for medical staff to perform surgery.

[0049] Optionally, the adjustment assembly includes a universal joint, and two adjacent connecting arms 9 are connected by the universal joint.

[0050] like Figure 1 As shown, in one embodiment, the auxiliary support device further includes a clamping assembly 10 for clamping the operating table, and the clamping assembly 10 is connected to the adjustment assembly. By providing the clamping assembly 10, a fixed connection between the auxiliary support device and the operating table is achieved, facilitating operation.

[0051] Optionally, the clamping assembly 10 includes a clamping block and multiple bolts. One side of the clamping block can be clamped onto the operating table or surgical table. By rotating the bolts, the bolts abut against the operating table or surgical table, thereby fixing the clamping assembly 10 to the operating table or surgical table, and further realizing the fixed connection between the auxiliary support device and the operating table or surgical table.
