Description

Technical Field

[0001] This utility model relates to a medical device, and more particularly to a multi-purpose adapter for a catheter that can be used to manipulate guidewires. Background Technology

[0002] A guidewire is a high-precision medical device commonly used in cardiac catheterization, vascular examinations, and interventional vascular treatments. It moves within narrow and tortuous blood vessels, guiding catheters or other medical devices to precise locations during treatment. Specifically, to allow the guidewire to smoothly guide the catheter through the blood vessel, the guidewire must first protrude a certain length from the catheter tip to guide its direction. During the movement to the desired location, the operator often needs to twist the guidewire or rotate the catheter to maneuver within the narrow passage.

[0003] In the prior art, there is a guidewire manipulator that can be set on the guidewire to assist the operator in applying torque to the guidewire by rotating the manipulator, allowing it to move within the catheter. However, it can only assist in providing torque to the guidewire, and still requires additional manpower to assist in the rotation, movement, and fixation of the catheter. Therefore, during surgery, additional manpower or additional tools are needed to fix the catheter to facilitate the movement of the guidewire relative to the catheter, which causes inconvenience to the surgery. If the catheter could be directly connected to the guidewire manipulator, the aforementioned problems could be improved.

[0004] In addition, guidewires sometimes need to be connected to other instruments to achieve further functional processing, such as cleaning catheters. These connections are mostly achieved using adapters. Combining the adapter for connecting instruments with the guidewire manipulator should effectively reduce the number of surgical instruments and allow the operator to perform the procedure without moving.

[0005] However, if the adapter, guidewire manipulator, and catheter are directly combined, the operator will rotate the instruments connected to the adapter while rotating the catheter. If these instruments include wire-like instruments or tubing, they may become entangled and affect the progress of the surgery.

[0006] Therefore, further structural design integration is still needed to combine the adapter and guidewire manipulator with the function of catheter connection. Utility Model Content

[0045] Please refer to the following first. Figures 1 to 4 and Figure 17 This is a first embodiment of a guidewire adapter proposed in this utility model. The guidewire adapter of this utility model is used to install a guidewire B. The guidewire adapter in this embodiment includes an adapter ring 10, a catheter connecting tube 20, a body assembly 30, and a filling ring 40.

[0046] Please refer to Figure 1 and Figures 3 to 7The adapter ring 10 has a first opening 11 and a second opening 12 on its two opposite sides, and an internal space 13 is formed within the adapter ring 10, and the internal space 13 communicates with the first opening 11 and the second opening 12. Specifically, the adapter ring 10 includes two pieces 101 spaced apart from each other and an annular wall 102. The annular wall 102 connects the periphery of the two pieces 101, thereby forming the internal space 13 between the two pieces 101 and the annular wall 102; wherein the first opening 11 and the second opening 12 are respectively formed on the two pieces 101, so that the internal space 13 communicates with the first opening 11 and the second opening 12, but is not limited thereto.

[0047] Please refer to Figure 1 , Figures 3 to 5 , Figure 8 ,and Figure 17 The catheter connecting sleeve 20 is rotatably disposed on the adapter ring 10. In this embodiment, the catheter connecting sleeve 20 is cylindrical and has a rotating end 21 and a connecting end 22 facing each other, while a first channel 23 is formed through the catheter connecting sleeve 20 and connects the rotating end 21 and the connecting end 22. When this invention is used with guidewire B, the guidewire passes through the first channel 23, and the user can connect a catheter A to the catheter connecting sleeve 20.

[0048] Specifically, the rotating end 21 of the conduit connecting tube 20 passes through the first opening 11 of the adapter ring 10 and extends into the internal space 13. In this embodiment, the rotating end 21 has a setting groove 211 and a first outer ring protrusion 24. The setting groove 211 is recessed in the end face of the rotating end 21, and the bottom of the setting groove 211 is further recessed to form a limiting groove 212. However, this is not a limitation. In other embodiments, the setting groove 211 may not be present, or the bottom of the setting groove 211 may not have the limiting groove 212.

[0049] The first outer ring rib 24 protrudes from the outer peripheral surface of the rotating end 21 and is located in the internal space 13 of the adapter ring 10. The first outer ring rib 24 abuts against the periphery of the first opening 11, thereby allowing the conduit connecting tube 20 to rotate relative to the adapter ring 10 without separating from the adapter ring 10.

[0050] The connecting end 22 extends away from the rotating end 21 and is used to connect the conduit. Specifically, in this embodiment, the end face of the connecting end 22 is recessed to form an outer annular groove 221. The outer annular groove 221 surrounds the first channel 23 and is separated from the first channel 23. In this way, the outer annular groove 221 allows the conduit A covering the guide wire B to be connected therein. Furthermore, in this embodiment, the groove wall of the outer annular groove 221 is formed with a threaded structure, so that it can be connected to the conduit A by screwing, but this is not a limitation.

[0051] The first channel 23 extends through the conduit connecting tube 20 and connects the connecting end 22 and the rotating end 21. In this embodiment, the first channel 23 forms an opening at the bottom of the limiting groove 212, and the first channel 23 is interconnected with the setting groove 211 through the limiting groove 212, but is not limited thereto.

[0052] Please refer to the following: Figure 1 , Figures 3 to 5 , Figure 9 and Figure 10 The body assembly 30 includes a connecting end 311, a transition end 321, and a second channel 33. The connecting end 311 and the transition end 321 are located at opposite ends of the body assembly 30. The second channel 33 passes through the body assembly 30 and connects the connecting end 311 and the transition end 321. The body assembly 30 is inserted through the second opening 12 of the transition ring 10 via the connecting end 311 and is disposed at the rotating end 21 of the conduit connecting tube 20. The conduit connecting tube 20 can rotate relative to the connecting end 311, and the second channel 33 is in communication with the first channel 23.

[0053] Specifically, in this embodiment, the body assembly 30 may include a main cylinder 31 and a locking cylinder 32, wherein the connecting end 311 is located in the main cylinder 31, and the connecting end 321 is located in the locking cylinder 32.

[0054] The main tube 31 passes through the adapter ring 10, with the connecting end 311 located at one end of the main tube 31. The main tube 31 further has an access end 312 and a first sub-channel 313. Specifically, the connecting end 311 and the access end 312 are located at opposite ends of the main tube 31, while the first sub-channel 313 passes through and connects the connecting end 311 and the access end 312. The connecting end 311 passes through the second opening 12 of the adapter ring 10 and extends into the internal space 13. The connecting end 311 is rotatably disposed in the mounting groove 211 of the rotating end 21 of the conduit connecting tube 20 relative to the conduit connecting tube 20.

[0055] The access end 312 is located at one end of the main cylinder 31 relative to the engagement end 311, and a locking groove 3121 is recessed into the end face of the access end 312. The locking groove 3121 includes a locking section 3122, the inner diameter of which gradually decreases from the access end 312 toward the engagement end 311. The first sub-channel 313 is part of the second channel 33, and the first sub-channel 313 penetrates and connects the engagement end 311 and the bottom of the locking groove 3121, thereby enabling the first sub-channel 313 and the locking groove 3121 to communicate with each other.

[0056] In this embodiment, the connecting end 311 may further have an inner cylinder wall 3111 and a second outer ring rib 3112. The inner cylinder wall 3111 circumferentially surrounds the second channel 33, and one end of the inner cylinder wall 3111 is provided in the limiting groove 212 in the setting groove 211 of the conduit connecting cylinder 20, thereby aligning the first channel 23 and the second channel 33 with each other and preventing the conduit connecting cylinder 20 from shifting relative to the body assembly 30 when it rotates, but this is not a limitation.

[0057] The second outer ring rib 3112 protrudes from the outer peripheral surface of the joint end 311 and is located in the inner space 13 of the transition ring 10. The second outer ring rib 3112 abuts against the periphery of the second opening 12, thereby preventing the body assembly 30 from detaching from the second opening 12, but this is not a limitation.

[0058] The locking cylinder 32 is movably disposed in the locking groove 3121 of the main cylinder 31. The adapter end 321 is located at one end of the locking cylinder 32, and the locking cylinder 32 further has a clamping end 322 and a second sub-channel 323. In this embodiment, the locking cylinder 32 is screwed into the locking groove 3121 of the main cylinder 31, thereby facilitating the user to adjust the amount of movement of the locking cylinder 32 in the locking groove 3121, but this is not a limitation. The clamping end 322 is located at one end of the locking cylinder 32 relative to the adapter end 321, and the clamping end 322 is located in the locking section 3122 of the locking groove 3121. The second sub-channel 323 is also part of the second channel 33. The second sub-channel 323 passes through both ends of the locking cylinder 32 and through the clamping end 322, and the inner diameter of the second sub-channel 323 at the position of the clamping end 322 is variable. The first sub-channel 313 and the second sub-channel 323 are interconnected and together form the second channel 33.

[0059] In this embodiment, the clamping end 322 includes a plurality of clamping blocks 3221 spaced apart from each other, and the clamping blocks 3221 surround the second sub-channel 323. The clamping blocks 3221 are spaced apart from each other in the circumferential and radial directions of the second sub-channel 323, and each clamping block 3221 is elastic, and can deform slightly in the direction of the force when the clamping block 3221 is subjected to a pushing force. Therefore, when the locking cylinder 32 moves relative to the locking groove 3121, the clamping blocks 3221 are pushed by the inner peripheral wall of the locking section 3122, which causes the clamping blocks 3221 to deform radially inward, further reducing the inner diameter of the second sub-channel 323 at the position of the clamping end 322, thereby clamping the guide wire and locking the position of the guide wire. However, the form of the clamping end 322 is not limited to this.

[0060] The body assembly 30 may also include a grip portion 34. The grip portion 34 is located between the engaging end 311 and the transition end 321, and in this embodiment, the grip portion 34 is disposed on the locking cylinder 32. The grip portion 34 has a middle section position 341 and two end positions 342, the middle section position 341 is connected to the two end positions 342, and the outer diameter of the grip portion 34 gradually decreases from the middle section position 341 to the two end positions 342, but this is not a limitation, and in other embodiments, the grip portion 34 may not be present.

[0061] The filling ring 40 is disposed between the joint end 311 and the bottom surface of the groove 211, filling the space between the joint end 311 and the bottom surface of the groove 211, thereby stabilizing the position of the body assembly 30 relative to the conduit connecting cylinder 20 in the axial direction, but not limited thereto.

[0062] Please refer to Figure 1 , Figures 4 to 6 ,and Figure 17 In this embodiment, guide wire B can be inserted from the connecting end 22 of the catheter connecting cylinder 20 into the first channel 23. Guide wire B then passes through the first channel 23 into the second channel 33 of the body assembly 30, and can then exit the present invention from the adapter end 321 of the body assembly 30. Thus, the present invention can move relative to guide wire B along its extension direction. Furthermore, the user can connect catheter A to the connecting end 22 of the catheter connecting cylinder 20. Specifically, in this embodiment, the user can use the connecting sleeve (not shown in the figure) configured on catheter A to connect it to the outer annular groove 221 by screwing. Since catheter A is fixedly connected to the catheter connecting cylinder 20, and guide wire B can move through the present invention, guide wire B can move relative to catheter A. When the user wants to fix the extension of one end of guidewire B beyond the extension of catheter A, the locking cylinder 32 can be moved relative to the main cylinder 31. This causes the clamping block 3221 of the clamping end 322 to be pushed by the inner wall surface of the locking section 3122 of the locking groove 3121, reducing the inner diameter of the second channel 33 in the locking section 3122. Therefore, the clamping block 3221 can clamp the guidewire B and fix the relative position between the guidewire B and the present invention, that is, fix the amount of protrusion of one end of guidewire B relative to catheter A. On the other hand, the adapter end 321 of the body assembly 30 can be provided for connecting other instruments, tubing, or lines (e.g., Figure 17 The form of the adapter 321 in the device C can be adjusted according to the actual connection requirements.

[0063] After setup, when the user wants to rotate catheter A, they can grasp the handle 34 of the main body assembly 30 with one hand and rotate the catheter connecting sleeve 20 with the other hand to rotate catheter A in a full circumference. Since the catheter connecting sleeve 20 is connected to the main body assembly 30 via the adapter ring 10, the catheter connecting sleeve 20 can rotate relative to the adapter ring 10, and the adapter ring 10 can also rotate relative to the main body assembly 30. Furthermore, the main body assembly 30 is connected to the catheter connecting sleeve 20 via a slot 211. Therefore, the catheter connecting sleeve 20 can rotate freely relative to the main body assembly 30 without causing the main body assembly 30 to rotate as well, thus preventing other instruments C connected to the main body assembly 30 from becoming entangled. On the other hand, when the user wants to twist guidewire B, they can still twist the main body assembly 30 to apply further torque to guidewire B.

[0064] Furthermore, in this embodiment, the inner wall 3111 of the engaging end 311 of the body assembly 30 is disposed in the limiting groove 212 at the bottom of the setting groove 211. This ensures that the first channel 23 and the second channel 33 will not disengage when the conduit connecting cylinder 20 rotates relative to the body assembly 30. Additionally, since the first outer ring rib 24 of the conduit connecting cylinder 20 abuts against the periphery of the first opening 11, and the second outer ring rib 3112 of the body assembly 30 abuts against the periphery of the second opening 12, the conduit connecting cylinder 20 and the body assembly 30 will not disengage from the adapter ring 10 and can rotate stably. Furthermore, the filling ring 40 disposed between the engaging end 311 and the bottom of the setting groove 211 also stabilizes the relative position of the conduit connecting cylinder 20 and the body assembly 30 in the axial direction.

[0065] Please refer to the following. Figures 11 to 14 This is the second embodiment of the present invention, which includes an adapter ring 10, a catheter connecting sleeve 20, and a body assembly 30A. The second embodiment is largely the same as the first embodiment, with the main difference being the body assembly 30A. Simply put, in the second embodiment, the body assembly 30A separates its function of connecting to the catheter connecting sleeve 20 from its function of locking the guidewire length. In the second embodiment, the body assembly 30A has a main sleeve 31A, and this embodiment can be as follows... Figures 15 to 16 The diagram further includes a locking unit 50A.

[0066] The main cylinder 31A of the second embodiment is similar to the main cylinder 31 of the first embodiment, but does not have the locking groove 3121. Specifically, in this embodiment, the main cylinder 31A passes through the adapter ring 10, the engaging end 311A ​​and the adapter end 314A are located at opposite ends of the main cylinder 31A, and the second channel 33A is located in the main cylinder 31A. The second channel 33A further includes an insertion section 331A, the inner diameter of which gradually decreases from the adapter end 314A toward the engaging end 311A.

[0067] The locking unit 50A is connected to the adapter 314A of the main cylinder 31A. In this embodiment, the locking unit 50A has a first sub-cylinder 51A and a second sub-cylinder 52A.

[0068] The first sub-tube 51A has a first end 511A, a second end 512A, a locking groove 5121A, and a third channel 513A. The first end 511A and the second end 512A are located at opposite ends of the first sub-tube 51A, and the first end 511A passes through the insertion section 331A, thereby connecting the first sub-tube 51A to the main tube 31A. The locking groove 5121A is recessed in the second end 512A and includes a locking section 5122A. The inner diameter of the locking section 5122A gradually narrows from the second end 512A toward the first end 511A, and the third channel 513A passes through and connects the first end 511A and the bottom of the locking groove 5121A.

[0069] The second sub-tube 52A is movably inserted through the first sub-tube 51A. The second sub-tube 52A has a clamping end 521A, a connecting end 522A, and a fourth channel 523A. The clamping end 521A and the connecting end 522A are located at opposite ends of the second sub-tube 52A, and the clamping end 521A passes through the locking section 5122A of the locking groove 5121A. The fourth channel 523A passes through and connects the clamping end 521A and the connecting end 522A of the second sub-tube 52A. The inner diameter of the fourth channel 523A at the position of the clamping end 521A is variable. The third channel 513A connects the fourth channel 523A and the second channel 33A, thereby allowing the guide wire to pass through the fourth channel 523A, the third channel 513A, and the second channel 33A.

[0070] In the second embodiment, the relationship between the first sub-tube 51A and the second sub-tube 52A is similar to that between the main tube 31 and the locking tube 32 in the first embodiment. The locking groove 5121A of the first sub-tube 51A corresponds to the locking groove 3121 of the main tube 31 in the first embodiment, while the clamping end 521A of the second sub-tube 52A corresponds to the clamping end 322 of the locking tube 32 in the first embodiment. Furthermore, in this embodiment, the grip portion 524A is provided on the second sub-tube 52A, but this is not a limitation.

[0071] The second embodiment is used in a manner largely similar to the first embodiment, with the main difference being that the function of locking the guidewire protrusion relative to the catheter is provided by the locking unit 50A. Furthermore, other instruments can be connected not only to the adapter end 314A of the main tube 31A but also to the connecting end 522A of the locking unit 50A. Therefore, the second embodiment offers more diverse instrument connections. Specifically, if the user does not require catheter insertion, the locking unit 50A can be directly used on the guidewire to control and apply torque to the guidewire, or to connect other instruments. On the other hand, if the user does not require locking the guidewire relative to the catheter length, the locking unit 50A can be removed, and other instruments can be connected to the adapter end 314A of the main tube 31A. In this way, the user can still freely rotate the catheter connected to the catheter connector 20 without affecting other instruments connected to the main tube 31A. In addition, the adapter end 314A of the second embodiment can also be used to connect existing guidewire torque manipulators, but is not limited thereto.

[0072] The guidewire adapter of this invention can move freely along the guidewire, connect catheters and other instruments, and fix the protruding length of the guidewire relative to the catheter. Furthermore, the user can rotate the catheter circumferentially without affecting other instruments connected to this invention, preventing multiple tubes or wires from becoming tangled or knotted. In addition, the catheter connecting sleeve 20 of this invention can rotate stably relative to the main body components 30 and 30A, ensuring stable connection between the first channel 23 and the second channel 33 without affecting the guidewire.
