Description

Technical Field

[0002] With the development of technology, the activation of surgical instruments is gradually being carried out, such as electrophysiological visual ablation catheters, visual guide sheaths, etc. The activation of these instruments has brought various benefits to the surgeon, such as reducing x-ray time and reducing the difficulty of surgery. While the activation of instruments brings benefits, it also brings some negative effects. With the increase in the number of active instruments used in a surgery, it also means that more connecting wires are needed. The main function of the connecting wire is to connect the active consumables with the equipment so that the active consumables can achieve their expected electrical properties. However, the introduction of such connecting tail wires has affected the surgeon's operation to a certain extent, reduced the fluency of the surgery to a certain extent, and affected the surgeon's operating experience. For example, during the operation, the tail wires are prone to entanglement and knotting. Or due to the continuous operation and rotation of the consumables, a single tail wire is twisted and knotted. This will increase the difficulty of the surgeon's surgery, increase the operation time, and reduce the surgeon's experience. Summary of the invention

[0034] [Example 1]

[0035] like Figure 1 As shown, an embodiment of the present invention provides a rotatable plug connection structure, comprising a male head 1 and a female head 2 that are detachably connected along an axial direction. When the male head 1 and the female head 2 are connected, the female head 2 is allowed to rotate relative to the male head 1 around the axis. The male head 1 and the female head 2 are connected to achieve conduction. The axes of the male head 1 and the female head 2 coincide after the connection. Therefore, the axis can be understood as the axis of the male head 1 or the axis of the female head 2.

[0036] The male head 1 and the female head 2 may exist independently, or the male head 1 and the female head 2 may be installed in other devices, such as a handle of a medical catheter.

[0037] See also Figure 2 and Figure 3 The male head 1 includes a first conductive structure 5, and the female head 2 includes a second conductive structure 10. When the female head 2 rotates relative to the male head 1, the first conductive structure 5 and the second conductive structure 10 slide and rub against each other so that the first conductive structure 5 and the second conductive structure 10 always maintain contact and conduction.

[0038] The rotatable plug connection structure provided in this embodiment can be used for the electrical connection between a medical catheter (such as an ablation catheter) and medical equipment such as a radiofrequency instrument and a three-dimensional system. When used for the electrical connection between a medical catheter and a medical device, the female head 2 and the male head 1 are respectively connected to the medical catheter and one of the medical devices, and then the female head 2 and the male head 1 are docked to complete the conduction. In the process of the operator operating the medical catheter to intervene in the human body to perform the corresponding operation, since the female head 2 and the male head 1 can rotate with each other, the connection line between the medical catheter and the medical device will not be entangled or knotted, so the operator's operating freedom can be improved, and the purpose of reducing the difficulty of the operation and reducing the operation time can be achieved.

[0039] In a preferred method of realizing that the male head 1 and the female head 2 can rotate relative to each other, as Figure 2 As shown, the male head 1 also includes a rotatable structure 4 rotatably arranged around the axis, such as Figure 3 As shown, the female connector 2 also includes a wiring housing 9. When the male connector 1 is connected to the female connector 2, the rotatable structure 4 extends into the inner cavity of the wiring housing 9 and is tightly connected to the inner side wall of the wiring housing 9. The rotatable structure 4 is used to drive the female connector 2 to rotate around the axis by rotating.

[0040] It can be understood that after the male connector 1 is inserted into the female connector 2, due to the friction between the wiring housing 9 and the rotatable structure 4, the entire female connector 2 and the rotatable structure 4 together form a rotatable unit, and the rotatable unit can rotate relative to the male connector 1 except the rotatable structure 4.

[0041] In order to facilitate the arrangement of the first conductive structure 5 and the second conductive structure 10, preferably, as Figure 2 As shown, the male connector 1 further includes a first insulating core 6, the rotatable structure 4 is rotatably connected to the first insulating core 6 around the axis of the first insulating core 6, the female connector 2 further includes a second insulating core 12, and the wiring housing 9 is arranged around the second insulating core 12; when the male connector 1 and the female connector 2 are connected, the first insulating core 6 and the second insulating core 12 abut against each other in the axial direction, and the first conductive structure 5 and the second conductive structure 10 are respectively arranged on the end faces of the first insulating core 6 and the second insulating core 12 that abut against each other for contact and conduction. While the wiring housing 9 is arranged around the second insulating core 12, it extends axially out of the end face of the second insulating core 12 that abuts against the first insulating core 6 to ensure that the female connector 2 can extend into the inner cavity of the wiring housing 9.

[0042] Please continue to see Figure 2 and Figure 3In this embodiment, the first conductive structure 5 is a first annular conductive member arranged around the axis, and the second conductive structure 10 is a second annular conductive member arranged around the axis. After the male connector 1 and the female connector 2 are connected, the projections of the first annular conductive member and the second annular conductive member on the cross section overlap.

[0043] In the present embodiment, specifically, one end of the male head 1 for connecting with the female head 2 has an annular groove, specifically, one end of the first insulating core 6 for abutting against the second insulating core 12 has an annular groove, and the first annular conductive member is assembled in the annular groove, and correspondingly, the second conductive structure 10 is a convex ring. When the male head 1 and the female head 2 are connected, the convex ring extends into the annular groove, contacts and conducts with the first annular conductive member located in the annular groove, and can rotate relative to each other.

[0044] In some other embodiments, the female head 2 may have an annular groove at one end for connecting with the male head 1, specifically, the second insulating core 12 may have an annular groove at one end for abutting against the first insulating core 6, the second annular conductive member is arranged in the annular groove, and the first conductive structure 5 is a convex ring. When the male head 1 and the female head 2 are connected, the convex ring extends into the annular groove and contacts and conducts with the second annular conductive member.

[0045] Furthermore, in some other embodiments, the convex ring may be replaced by a corresponding needle connector, and the needle connector extends into the annular groove to contact and conduct with the corresponding annular conductive member.

[0046] Further preferably, the male connector 1 includes a plurality of the first conductive structures 5, and the female connector 2 includes a plurality of the second conductive structures 10; the plurality of the first conductive structures 5 are distributed in concentric rings around the axis, and / or the plurality of the second conductive structures 10 are distributed in concentric rings around the axis; the plurality of the first conductive structures 5 and the plurality of the second conductive structures 10 are in contact and conduction in a one-to-one correspondence. Figure 2 As shown, the male connector 1 includes a plurality of first annular conductive members, which are arranged in a plurality of concentric annular grooves, and thus are concentric annularly distributed. Figure 3 As shown, the female connector 2 includes a plurality of convex rings, which are also distributed in a concentric shape. After the male connector 1 is connected to the female connector 2, the plurality of convex rings extend into the grooves and contact and conduct with the plurality of the first annular conductive members one by one, so as to form a plurality of active paths, which are insulated from each other. Each of the paths can be used for different purposes, such as radio frequency discharge, three-dimensional electrical positioning, temperature measurement, etc. Similarly, the plurality of convex rings can be replaced by a plurality of pin connectors, which will not be described in detail here.

[0047] Figure 2 and Figure 3 As shown in the figure, the male connector 1 includes two first conductive structures 5, and the female connector 2 includes two second conductive structures 10. However, it should be understood that the number of the first conductive structures 5 and the second conductive structures 10 does not constitute a limitation to the present application. It is only necessary to ensure that at least one active path can be formed after the male connector 1 and the female connector 2 are connected to each other.

[0048] Further, such as Figure 2 As shown, the male connector 1 further includes a first conductor 8, such as Figure 3 As shown, the female connector 2 further includes a second wire 13, and the first wire 8 and the second wire 13 are respectively used to connect to the first conductive structure 5 and the second conductive structure 10, and extend from one end of the first insulating core 6 and the second insulating core 12 away from each other, so as to be respectively used to connect to the medical catheter and the medical device as described above.

[0049] The first conductive wire 8 and the second conductive wire 13 may have one or more separate conductive wire cores. When there are multiple first conductive structures 5 and multiple second conductive structures 10, the first conductive wire 8 is connected to multiple first conductive structures 5 through different conductive wire cores, and the second conductive wire 13 is electrically connected to multiple second conductive structures 10 through different conductive wire cores, so as to achieve the purpose of forming multiple active paths.

[0050] In this embodiment, optionally, Figure 2 As shown, the rotatable structure 4 adopts a bearing structure. Specifically, the rotatable structure 4 includes a first part and a second part. The first part is arranged around the first insulating core 6 and is fixedly connected to the first insulating core 6. The second part is rotatably arranged around the first part. After the male plug 1 extends into the inner cavity of the wiring housing 9, there is friction between the outer wall of the second part and the inner wall of the wiring housing 9. It can be understood that the first part and the second part are both in the shape of an annular sleeve, and the two can be connected by a rolling body, such as a rolling ball or a rolling column, so that the second part can rotate around the first insulating core 6. In some other embodiments, the first part and the second part can also adopt other relatively rotatable methods, which will not be repeated here.

[0051] In addition, in some other embodiments, the rotatable structure 4 may also be designed as an integrated structure, and the entire structure rotates around the first insulating core 6. When the rotatable structure 4 is designed as an integrated structure, the rotatable structure 4 may be made of lubricating polymer materials such as PTFE.

[0052] Optionally, the first insulating core 6 is covered with a male sheath 7, and the male sheath 7 does not extend axially beyond the connection end (the end for docking with the female connector 2) of the first insulating core 6. Preferably, the end faces of the connection ends of the two are flush. When the rotatable structure 4 includes the first part and the second part, the second part is fixed to the male sheath 7. When the rotatable structure 4 adopts an integrated design, limiting grooves distributed along the circumference can be provided on the male sheath 7, and the rotatable structure 4 rotates around the first insulating core 6 along the limiting grooves.

[0053] In addition to being used to limit the rotatable structure 4 , the male sheath 7 can also extend to surround the first wire 8 to increase the connection strength between the first wire 8 and the first conductive structure 5 .

[0054] In addition, the male connector 1 may further include a connector shell 3, which is arranged around the rotatable structure 4 and fixedly connected to the male connector sheath 7, and the first insulating core 6 and the rotatable structure 4 extend axially out of one end of the connector shell 3 for connection with the female connector 2, so that when the male connector 1 is docked with the female connector 2, the connecting ends of the first insulating core 6 and the rotatable structure 4 can extend into the wiring shell 9, and the connector shell 3 serves to limit the axial movement of the rotatable structure 4.

[0055] For the female connector 2, Figure 3 As shown, it may also include a female head sheath 11, which is sleeved between the second insulating core 12 and the wiring shell 9, and the female head sheath 11 does not extend out of the connection end (the end for docking with the male head 1) of the second insulating core 12 in the axial direction. Preferably, the end faces of the connection ends of the two are flush; similarly, the female head sheath 11 can extend to surround the second wire 13 to increase the connection strength between the second wire 13 and the second conductive structure 10. In order to match the structural setting of the male head 1, the first insulating core 6 and the second insulating core 12 can be designed to have the same diameter, the sum of the wall thickness of the male head sheath 7 and the wall thickness of the rotatable structure 4 is equal to the wall thickness of the female head sheath 11, the inner diameter of the wiring shell 9 matches the outer diameter of the rotatable structure 4, and the outer diameter of the wiring shell 9 matches the outer diameter of the joint shell 3.

[0056] From the above description, it can be seen that in the present application, the design of the female sheath 11 and the male sheath 7 is mainly for the convenience of structural design and assembly, and the existence of the female sheath 11 and the male sheath 7 does not constitute a limitation to the present application.

[0057] [Example 2]

[0058] In the first embodiment, there is friction between the outer wall of the rotatable structure 4 and the inner wall of the wiring housing 9, so that the female connector 2 and the rotatable structure 4 can rotate with each other. Figure 5 As shown, the outer side wall of the rotatable structure 4 is designed to have a groove 18, and the inner side wall of the wiring housing 9 has an elastically deformable protrusion 17, so that Figure 6 As shown, when the male connector 1 is docked with the female connector 2, the protrusion 17 is embedded in the groove 18 along a direction perpendicular to the axis to increase the connection strength between the rotatable structure 4 and the wiring housing 9 to avoid separation of the rotatable structure 4 and the wiring housing 9 during operation.

[0059] [Example 3]

[0060] Please continue to see Figure 5 and Figure 6 , different from the above embodiment, in this embodiment, the second insulating core 12 has a set axial movement stroke relative to the wiring housing 9, and the female connector 2 further includes an elastic structure 16, which is used to give the second insulating core 12 an axial elastic support force so that the second insulating core 12 can move axially. The elastic structure 16 can be, for example, a spring or an elastic member with folds.

[0061] Specifically, one of the side wall of the second insulating core 12 and the inner side wall of the wiring housing 9 may be provided with a stopper 15 protruding outward, and the other may be provided with a stopper groove 14 extending in a direction parallel to the axis, wherein the stopper 15 extends into the stopper groove 14 and moves in the stopper groove 14 to limit the movement of the second insulating core 12 within the set axial movement stroke, that is, the set axial movement stroke is defined by the stopper groove 14, and the extension length of the stopper groove 14 limits the maximum stroke length of the second insulating core 12 in a single direction. After the female connector 2 is docked with the male connector 1, the elastic structure 16 can provide additional elastic support force to the second insulating core 12, so that the first conductive structure 5 maintains contact with the second conductive structure 10, and prevents or avoids poor conductivity during rotation.

[0062] When the female connector 2 includes the female connector sheath 11, since the female connector sheath 11 is disposed between the second insulating core 12 and the wiring housing 9, the limiting member 15 or the limiting groove 14 should be provided on the inner side wall of the female connector sheath 11 to limit the axial movement of the second insulating core 12. Figure 5The example shown is that the side wall of the second insulating core 12 has a limiting piece 15 protruding outward, and the inner side wall of the female connector sheath 11 has a limiting groove 14.

[0063] In some other embodiments, the female connector 2 may not be provided with the female connector sheath 11. In this case, the diameter of the second insulating core 12 may be designed to be larger than the outer diameter of the first insulating core 6 and equal to the sum of the diameter of the first insulating core 6 and the wall thickness of the female connector sheath 11. Alternatively, the diameter of the second insulating core 12 is equal to that of the first insulating core 6, and the wiring housing 9 adopts a variable inner diameter design, in which the inner diameter of the portion of the wiring housing 9 surrounding the second insulating core 12 is equal to the diameter of the second insulating core 12, and the portion extending outside the connection end of the second insulating core 12 has a larger inner diameter, which is equal to the sum of the diameter of the first insulating core 6 and the wall thickness of the rotatable structure 4.

[0064] [Example 4]

[0065] Different from the third embodiment, in this embodiment, the first annular conductive member is arranged on a plane. Specifically, one end of the male connector 1 or the female connector 2 used for connecting to each other has a plane, and the first annular conductive member is arranged on the plane. The pin connector or the second annular conductive member is in contact and conduction with the first annular conductive member on the plane.

[0066] As an example, see Figure 7 and Figure 8 The first conductive structure 5 is a first annular conductive member, and the second conductive structure 10 is a pin-type connector. After the male connector 1 is docked with the female connector 2, the pin-type connector abuts against the first annular conductive member and maintains contact during the rotation process.

[0067] In summary, the present invention provides a rotatable plug connection structure, including: a male head and a female head that are detachably connected along an axial direction; when the male head is connected to the female head, the female head is allowed to rotate relative to the male head around the axis; the male head includes a first conductive structure, and the female head includes a second conductive structure. When the female head rotates relative to the male head, the first conductive structure and the second conductive structure slide and rub against each other, so that the first conductive structure and the second conductive structure always maintain contact and conduction. By using the rotatable plug connection structure provided by the present invention, the operator can reduce or avoid the problem of tail wire entanglement and knotting during operation, improve the operator's operating freedom, and thus achieve the purpose of reducing the difficulty of surgery and reducing the operation time.
