Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a multi-port valve rotary drive gear and consumable box for a vascular interventional surgery robot. Background Technology

[0002] Multi-port valves are commonly used auxiliary devices in interventional medicine, with Y-valve being particularly prevalent. They provide a fluid pathway into the interventional system and are primarily used during interventional procedures to assist in the introduction of contrast agents, in conjunction with guidewires or catheters, and to prevent bleeding. When used with guidewires or catheters, the Y-valve connection end needs to be installed onto the multi-port valve rotary drive gear. The usual installation method is to first install the Y-valve into the Y-valve mounting compartment within the consumables box, and then axially install the multi-port valve rotary drive gear onto the Y-valve connection end. However, in practice, the axial installation position of the multi-port valve rotary drive gear and the Y-valve often fails to meet requirements. Either the Y-valve connection end protrudes excessively from the axial through-hole of the multi-port valve rotary drive gear, or the axial installation is insufficient. This results in a misalignment between the multi-port valve rotary drive gear and the gear structure within the consumables box, preventing proper meshing and hindering surgical efficiency. Utility Model Content

[0003] The purpose of this application is to provide a multi-port valve rotary drive gear and consumable box for a vascular interventional surgery robot, aiming to solve the problem in the related art that when the multi-port valve rotary drive gear is installed to the end of the multi-port valve, the multi-port valve rotary drive gear is not installed in place, and when the multi-port valve is placed in the consumable box, the position of the multi-port valve rotary drive gear and the gear structure in the consumable box do not correspond, so they cannot mesh normally.

[0004] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of this application.

[0005] According to a first aspect of this application, a multi-port valve rotary drive gear for a vascular interventional surgical robot is provided, comprising:

[0006] The gear body has an axial through hole for inserting the rotating end of the multi-way valve. One axial end of the gear body is an insertion end for inserting the rotating end of the multi-way valve, and the other axial end of the gear body is a gear end.

[0007] An axial limiting structure is provided on the gear body and located at the gear end. The axial limiting structure has a limiting portion extending from the gear body toward the central axis of the axial through hole. At least a portion of the limiting portion is located in the axial projection of the axial through hole. When the multi-way valve rotation drive gear is assembled with the multi-way valve, the limiting end face of the limiting portion toward the insertion end abuts against the end face of the rotating end of the multi-way valve.

[0008] In one exemplary embodiment of this application, the axial limiting structure includes one or more limiting bosses disposed along the periphery of the axial through hole, and the limiting portion is a radial extension of the limiting boss that extends radially into the axial through hole.

[0009] In one exemplary embodiment of this application, the radial extension is configured to extend from the edge of the axial through hole into the axial through hole by a distance of 1 / 4 to 1 / 3 of the diameter of the axial through hole.

[0010] In one exemplary embodiment of this application, the limiting boss extends axially to form an axial support portion on the end face of the gear end of the rotary drive gear, and the radial extension portion extends radially from the end of the axial support portion.

[0011] In one exemplary embodiment of this application, the axial support extends axially from the gear end face by a distance that is 1 / 3 to 1 / 2 of the radial extension.

[0012] In one exemplary embodiment of this application, the limiting boss is provided as a plurality of them, and the plurality of limiting bosses are evenly distributed along the edge of the axial through hole.

[0013] In one exemplary embodiment of this application, the end of the radial extension is provided with a chamfer.

[0014] In one exemplary embodiment of this application, the multi-way valve rotary drive gear further includes a silicone ring, which is disposed at one end of the axial through hole in the multi-way valve rotary gear. The silicone ring is provided with a relief groove corresponding to the limiting part. When the multi-way valve connecting end is inserted into the axial through hole of the multi-way valve rotary drive gear along the axial direction, the relief groove passes through the limiting part.

[0015] In one exemplary embodiment of this application, one or more axially extending ribs are provided on the side wall of the multi-way valve connection end, and a limiting groove matching the ribs is provided on the inner circumference of the silicone ring. The silicone ring is connected to the gear end through the cooperation of the limiting groove and the ribs.

[0016] According to a second aspect of this application, a consumable box for a vascular interventional surgery robot is provided, including a box body and the aforementioned multi-way valve rotary drive gear, the multi-way valve rotary drive gear being disposed within the box body.

[0017] This application has some or all of the following beneficial effects:

[0018] The multi-way valve rotary drive gear of this application includes a gear body and an axial limiting structure. The gear body has an axial through hole for insertion of the rotating end of the multi-way valve. One end of the gear body is an insertion end for insertion of the rotating end of the multi-way valve, and the other end is the gear end. The axial limiting structure is located on the gear end face of the gear end. The axial limiting structure has a limiting part that can extend from the gear end face into the axial through hole. When the multi-way valve rotary drive gear is installed onto the multi-way valve, the limiting end face of the limiting part facing the insertion end abuts against the end face of the multi-way valve connection end, thereby limiting the multi-way valve rotary drive gear's movement within the multi-way valve. The installation position of the rotating end also indicates that the axial relative position of the multi-way valve rotary drive gear and the multi-way valve is in place. With the addition of the axial limiting structure, after the multi-way valve is installed into the consumable box, the multi-way valve rotary drive gear can be directly installed into place. The limitation of the axial limiting structure avoids the situation where the axial installation position of the multi-way valve rotary drive gear and the multi-way valve is not in place, so that the multi-way valve rotary drive gear can mesh normally with the gear structure in the consumable box after being installed into the multi-way valve, thereby improving the installation speed and thus improving the efficiency of surgery.

[0029] The terms “a,” “one,” “the,” and “at least one” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects. Example 1

[0030] This embodiment provides a specific implementation of the multi-port valve rotary drive gear 2 for a vascular interventional surgical robot, such as... Figure 1 and Figure 2 As shown, the multi-way valve rotary drive gear 2 includes a gear body and an axial limiting structure 4. The gear body has an axial through hole for the insertion of the rotating end 3 of the multi-way valve 1. One axial end of the gear body is an insertion end 22 for the insertion of the rotating end 3 of the multi-way valve 1, and the other axial end of the gear body is a gear end 21. The axial limiting structure 4 is provided on the gear body and located at the gear end 21. The axial limiting structure 4 has a limiting part extending from the gear body toward the central axis of the axial through hole. At least part of the limiting part is located in the axial projection of the axial through hole. When the multi-way valve rotary drive gear 2 and the multi-way valve 1 are assembled in place, the limiting end face of the limiting part facing the insertion end 22 abuts against the end face of the rotating end 3 of the multi-way valve 1. When assembling the rotary drive gear 2 onto the multi-way valve 1, the rotating end 3 of the multi-way valve 1 is inserted from the insertion end 22 of the gear body until the end face of the rotating end 3 of the multi-way valve 1 abuts against the limiting end face of the limiting part. At this point, it indicates that the multi-way valve 1 and the rotary drive gear 2 are properly assembled. At the same time, the limiting part also restricts the fixed position of the multi-way valve 1, avoiding the defect of excessive movement of the multi-way valve 1. Thus, when assembling, the operator can directly assemble the multi-way valve 1 and the rotary drive gear 2 until the rotating end 3 of the multi-way valve 1 abuts against the limiting part. The operation is simple, and there is no need to worry about axial over-installation. With the obstruction and indication of the limiting part, there is no need to worry about incomplete assembly. As long as the rotating end 3 of the multi-way valve 1 does not abut against the limiting part, it means that it is not yet properly assembled. The addition of a limiting part to the gear end 21 of the rotary drive gear 2 can both restrict the position of the multi-way valve 1 and indicate the situation when the multi-way valve 1 is properly installed. The structure is simple and the operation is convenient.

[0031] In this embodiment, the illustrations use a Y-valve as an example of a multi-port valve 1. Taking the Y-valve as an example, it includes a main pipe and a branch pipe connected to each other. The main pipe includes a rotating end and an insertion end positioned opposite each other. The rotating end of the Y-valve is connected to a catheter. When the rotating part of the rotating end of the Y-valve rotates, it can drive the catheter to rotate synchronously. The insertion end of the Y-valve is used for guidewire insertion, and the branch pipe of the Y-valve is used for fluid injection. During vascular interventional surgery, such as... Figure 3As shown, the Y valve needs to be installed in the consumable box 6 and used in conjunction with the consumable actuator 7 and gear structure 8. The consumable actuator 7 is used to drive the guide wire to move. Its movement can be rotation, movement, or a combination of rotation and movement. The gear structure 8 is used to mesh with the rotating gear and drive the rotating gear to rotate. The two ends of the multi-way valve 1 are the insertion end and the rotating end 3, respectively. The insertion end of the multi-way valve 1 is used for inserting interventional consumables, and the rotating end 3 is connected to the catheter and used to drive the catheter to rotate. The rotating end of the multi-way valve 1 is used to insert into the rotating drive gear 2. The rotating drive gear 2 meshes with the gear structure 8 in the consumable box 6. Under the drive of the gear structure 8, the rotating drive gear 2 drives the rotating end of the multi-way valve 1 to rotate, thereby driving the catheter connected to it to rotate.

[0032] Furthermore, a drive motor 9 is installed in the drive box (not shown in the figure) located below the consumable box 6. The drive shaft of the drive motor 9 is connected to a motor bevel gear 91. The motor bevel gear 91 meshes with a first bevel gear 81 in the gear structure 8. The first bevel gear 81 is connected to a second bevel gear 84 via a spline sleeve 82 and a spline shaft 83. The second bevel gear 84 is located inside the consumable box 6 and meshes with a rotary drive gear 2. The rotation of the drive motor 9 drives the rotation of the motor bevel gear 91, which in turn drives the first bevel gear 81 and the second bevel gear 84 to rotate. The second bevel gear 84 then drives the rotary drive gear 2 to rotate.

[0033] In this embodiment, the axial limiting structure 4 includes one or more limiting bosses spaced apart along the periphery of the axial through hole, and the limiting part is a radial extension 41 of the limiting boss extending radially into the axial through hole. Specifically, the limiting boss can be integrally formed with the rotary drive gear 2, or it can be connected to the rotary drive gear 2 by welding, bonding or other means. This application does not impose specific restrictions on this, and production can be selected according to the actual situation.

[0034] Furthermore, the radial extension 41 is configured to extend into the axial through hole from the edge of the axial through hole by a distance of 1 / 4 to 1 / 3 of the diameter of the axial through hole. This distance limitation allows the radial extension 41 to effectively abut against the rotating end 3 of the multi-way valve 1, while also allowing space for the central hole to facilitate the smooth passage of the guide wire. The radial extension 41 also does not affect the passage of the guide wire. In other embodiments, the radial extension 41 may also be a cross-shaped structure on the gear end 21 surface of the rotary drive gear 2, with a through hole in the middle to allow the insertion consumable to pass through.

[0035] In other embodiments, the axial limiting structure 4 may also be a limiting plate, limiting block, limiting rod, or other structure that extends radially from the end face of the gear end 21 of the rotary drive gear 2 toward the central axis of the axial through hole, as long as it can effectively abut against the end of the rotating end 3 of the multi-way valve 1.

[0036] In this embodiment, the limiting boss forms an axial support portion 42 on the axially extending portion of the gear end 21 of the rotary drive gear 2. The axial support portion 42 can supplement the axial distance of the radial extension portion 41 to adapt to different installation spaces. The axial support portion 42 extends axially from the gear end face of the rotary drive gear 2, and the radial extension portion 41 extends radially at the end of the axial support portion 42. The axial support portion 42 and the radial extension portion 41 together form the limiting boss. The radial extension portion 41 and the axial support portion 42 can be integrally formed, or they can be connected together by welding, bonding, snap-fitting, etc., without specific limitations.

[0037] In this embodiment, the axial support portion 42 extends axially from the gear end face by a distance that is 1 / 3 to 1 / 2 of the radial extension portion 41. By limiting the length of the axial support portion 42, the distance between the radial extension portion 41 and the gear end face of the rotary drive gear 2 can be limited. Specifically, the axial support portion 42 is an axially extending support rod, and the radial extension portion 41 is a radially extending baffle.

[0038] In this embodiment, multiple limiting bosses are provided, and these bosses are evenly distributed along the edge of the axial through hole. By providing multiple limiting bosses, the end face of the rotating end 3 of the multi-way valve 1 can be evenly stressed, ensuring the blocking effect on the rotating end 3 of the multi-way valve 1. In some other embodiments, only one limiting boss may be provided, as long as it can prevent the rotating end 3 of the multi-way valve 1 from continuing to move after reaching the installation position.

[0039] In this embodiment, the end of the radial extension 41 is chamfered. The chamfer can protect the end face of the rotating end 3 of the multi-way valve 1 from being scratched, thus ensuring the reliability of the multi-way valve 1.

[0040] In this embodiment, the multi-way valve rotary drive gear 2 also includes a silicone ring 5. The silicone ring 5 is disposed at one end of the axial through hole in the multi-way valve rotary gear. The silicone ring 5 is provided with a relief groove 52 corresponding to the limiting part. When the rotating end 3 of the multi-way valve 1 is inserted into the axial through hole of the multi-way valve rotary drive gear 2 along the axial direction, the relief groove 52 passes through the limiting part. Specifically, the silicone ring 5 is disposed between the rotating end 3 of the multi-way valve 1 and the axial through hole of the rotary drive gear 2. The silicone ring 5 is relatively fixedly installed at the insertion end 22 of the rotary drive gear 2. When the multi-way valve 1 is assembled with the rotary drive gear 2, the radial extension 41 can pass through the relief groove 52 and abut against the end face of the rotating end 3 of the multi-way valve 1. The length of the relief groove 52 can be set to correspond to the length of the axial support part 42. Of course, it can also be adjusted according to the actual situation, and there is no specific limitation.

[0041] In this embodiment, one or more axially extending ribs 31 are provided on the side wall of the rotating end 3 of the multi-way valve 1. A limiting groove 51 matching the ribs 31 is opened on the inner circumference of the silicone ring 5. The silicone ring 5 is connected to the gear end 21 through the cooperation of the limiting groove 51 and the ribs 31. Through the cooperation of the ribs 31 and the limiting groove 51, the rotating end 3 of the multi-way valve 1 can be easily inserted into the silicone ring 5 to complete the assembly with the rotary drive gear 2. At the same time, through the cooperation of the ribs 31 and the limiting groove 51, the rotation of the multi-way valve 1 itself can be restricted, so as to prevent the multi-way valve 1 from rotating during the assembly process and affecting the motion transmission.

[0042] Working principle:

[0043] This application provides an axial limiting structure 4, specifically a radial extension 41, at the end face of the gear end 21 of the rotary drive gear 2 to block the end face of the rotating end 3 of the multi-way valve 1. When assembling the multi-way valve 1 with the rotary drive gear 2, the rotating end 3 of the multi-way valve 1 is inserted from the insertion end 22 of the rotary drive gear 2 until the end face of the rotating end 3 of the multi-way valve 1 abuts against the radial extension 41. At this point, due to the blocking effect of the radial extension 41, the multi-way valve 1 can no longer move towards the gear end 21, thus indicating that the multi-way valve... The assembly of the multi-way valve 1 with the rotary drive gear 2 can prevent excessive movement of the multi-way valve 1. A limiting groove 51 is opened on the silicone ring 5, and an axially extending rib 31 is provided on the side of the rotating end 3 of the multi-way valve 1. Through the cooperation of the rib 31 and the limiting groove 51, not only can the rotating end 3 of the multi-way valve 1 be guided into the silicone ring 5 to complete the assembly with the rotary drive gear 2, but the relative rotation between the multi-way valve 1 and the silicone ring 5 can also be restricted, so as to avoid the relative rotation between the multi-way valve 1 and the silicone ring 5 during the assembly process and thus avoid assembly errors.
