Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially is involved in a kind of medical conductive connection structure and electrosurgical equipment. BACKGROUND

[0002] The application of electrosurgical technology originated in the early 20th century, and the first high-frequency generator in the world was designed and developed by a German engineer using spark plug ignition technology and controllable current technology, which changed the traditional surgical operation mode. With the development and application of electrosurgery in the medical field, more and more electrosurgical equipment has emerged, and the accessories and consumables matched with the electrosurgical equipment have also appeared like bamboo shoots after a spring rain.

[0003] Therefore, the electrical connection between the accessories or consumables and the electrosurgical equipment, and the electrical connection between the consumables and the electrical elements of the accessories have become the focus. At present, the above-mentioned electrical connection is mostly fixed connection, such as welding, riveting, etc. However, fixed connection may cause the two structures of the electrical connection to be unable to move relative to each other. For example, when the electrosurgical equipment is a high-frequency cutting knife, the cutting head of the high-frequency cutting knife and the conductive plug cannot move relative to each other, which limits the structure of the conductive plug and causes the conductive cable to be easily entangled during the operation, affecting the operation of medical personnel.

[0004] To solve the above problems, patent CN102379739A discloses a kind of anti-winding type multifunctional endoscope high-frequency cutting knife, which enables the conductive plug and the cutting head to rotate relative to each other by the elastic compression between the conductive ring or the conductive steel ball and the conductive spring. Although the above-mentioned patent solves the problem of relative rotation between the conductive plug and the cutting head, the contact between the conductive ring or the conductive steel ball and the conductive spring is single-point contact, and the contact compression force is one-way compression. When the conductive plug is subjected to torsion, the contact point between the conductive ring or the conductive steel ball and the conductive spring is easy to shift, which causes the electrical connection to be unreliable.

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0048] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0049] Some embodiments of the present application will be described in detail below in combination with the drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0050] Embodiment:

[0051] As shown in Figure 1 , Figure 2 and Figure 3 , the medical conductive connecting structure provided by the present embodiment comprises an energy access piece 1, a conductive rod 2 and a conductive piece 3; as shown in Figures 4-15As shown, the energy access piece 1 is provided with a mounting hole 10 between two sides thereof, the conductive rod 2 is arranged in the mounting hole 10 and can rotate relative to the energy access piece 1; the mounting hole 10 is provided with an elastic part distributed along the circumferential direction thereof and extending along the axial direction thereof, the elastic part is used for deforming along the radial direction of the mounting hole 10 to apply radial pressure to the conductive rod 2, and the conductive rod 2 is electrically connected to the energy access piece 1 through the elastic part.

[0052] The medical conductive connection structure provided by the embodiment is applied to electrosurgical equipment such as a high-frequency surgical knife, and correspondingly, the energy access piece 1 in the medical conductive connection structure can be a conductive plug connected with a conductive cable at the rear, and the conductive rod 2 can be a consumable such as a knife head or a metal catheter. During use, if the conductive cable rotates around the conductive rod 2, the wire plug (i.e., the energy access piece 1) will also rotate. Since the energy access piece 1 is provided with the mounting hole 10, the conductive rod 2 is arranged in the mounting hole 10 and can rotate relative to the energy access piece 1, so that the energy access piece 1 will rotate relative to the conductive rod 2 when it is driven to rotate by the conductive cable, and will not cause the conductive cable to be wound to affect the operation of medical staff.

[0053] It should be noted that during the rotation of the energy access piece 1 relative to the conductive rod 2, the elastic part in the mounting hole 10, which is distributed along the circumferential direction thereof and extends along the axial direction thereof, will deform along the radial direction of the mounting hole to apply radial pressure to the conductive rod 2, so that the elastic part will provide multi-point support along the circumferential direction and the axial direction of the mounting hole 10 between the energy access piece 1 and the conductive rod 2 during the relative rotation. At this time, even if the energy access piece 1 is subjected to a torsion force, it will not cause the relative displacement between the energy access piece 1 and the conductive rod 2, thereby effectively ensuring the contact stability and electrical connection reliability between the conductive rod 2 and the energy access piece 1, and improving the safety and reliability of the operation.

[0054] Compared with the prior art, the medical conductive connection structure provided by the embodiment can use the radial deformation of the elastic part distributed along the circumferential direction of the mounting hole 10 and extending along the axial direction of the mounting hole 10 to provide stable support for the energy access piece 1 during the relative rotation between the energy access piece 1 and the conductive rod 2, so that the contact stability and electrical connection reliability between the conductive rod 2 and the energy access piece 1 can be effectively ensured even if the energy access piece 1 is subjected to a torsion force.

[0055] In the embodiment, as shown in Figure 18 the side wall of the energy access piece 1 located on the circumferential side of the mounting hole 10 is made of an elastic material to form an elastic part, or the circumferential side wall of the conductive rod 2 located in the mounting hole 10 is made of an elastic material to form an elastic part; and the elastic part is provided with a deformation joint 11 extending along the axial direction of the mounting hole 10, the deformation joint 11 is used for enabling the elastic part to deform along the radial direction of the mounting hole 10; or as shown in Figures 2-15As shown, the elastic part is a conductive element 3 with elasticity. The conductive element 3 is installed in the mounting hole 10. The conductive element 3 is distributed circumferentially along the mounting hole 10 and forms a mounting channel extending axially along the mounting hole 10. The conductive rod 2 passes through the mounting channel.

[0056] like Figure 18 As shown, when the sidewall of the energy access component 1 located around the mounting hole 10 is made of elastic material to form an elastic part, or when the circumferential sidewall of the conductive rod 2 located inside the mounting hole 10 is made of elastic material to form an elastic part, the diameter of the mounting hole 10 can be smaller than the diameter of the conductive rod 2. At this time, there is an interference fit between the conductive rod 2 and the mounting hole 10. The deformation slot 11 on the elastic part provides deformation space for the elastic part to deform radially along the mounting hole 10. After the elastic part is deformed, it can use its own elasticity to apply radial extrusion force to the conductive rod 2, thereby effectively ensuring the stability of the relative rotation process between the conductive rod 2 and the energy access component 1.

[0057] To improve the deformation effect and stability of the elastic part during the deformation process, in this embodiment, it is preferable that the deformation seam 11 on the elastic part of the mounting hole 10 is located on the side of the energy access component 1 away from the conductive cable.

[0058] like Figures 2-15 As shown, when the elastic part is an elastic conductive element 3, the diameter of the mounting hole 10 can be larger than the diameter of the conductive rod 2. However, in order to ensure the effectiveness of the elastic part, the conductive element 3 needs to be in a radially deformed energy storage state between the mounting hole 10 and the conductive rod 2.

[0059] It should be noted that, compared to existing technologies, regardless of whether the elastic part is formed by the sidewall of the energy access component 1 located around the mounting hole 10 or the circumferential sidewall of the conductive rod 2 located within the mounting hole 10, or whether the elastic part is an elastic conductive component 3, the medical conductive connection structure can be assembled by installing the conductive rod 2 into the mounting hole 10. There is no need to connect the conductive ring or conductive steel ball to the conductive spring, which effectively simplifies the assembly process and reduces product costs. Furthermore, since the elastic part can deform radially along the mounting hole 10, the medical conductive connection structure provided in this embodiment can also be used with conductive rods 2 of various sizes.

[0060] It should also be noted that, such as Figure 1 As shown, electrosurgical equipment typically includes an operating section 4, an insertion section 5, and an application section 6. The operating section 4 and the insertion section 5 are connected to both ends of the conductive rod 2, respectively. The application section 6 is installed at the end of the insertion section 5 furthest from the operating section 4. The application section 6 contains surgical tools such as clamps or forceps. The insertion section 5 is used to enter the target surgical position. Medical personnel can use the operating section 4 to move the conductive rod 2 along its own axis, thereby... Figure 16 and Figure 17As shown, the drive application unit 6 extends or retracts, or the drive application unit 6 opens or closes.

[0061] Based on the requirement for axial movement of the conductive rod 2, the conductive rod 2 in this embodiment can also move relative to the energy input component along its own axial direction.

[0062] Since the conductive rod 2 may need to rotate or move along its own axis during use, it will experience wear after a long period of use. However, since the elastic part can deform radially along the mounting hole 10, even if the conductive rod 2 wears out over time, the elastic part can still be tightly connected to the conductive rod 2 through its own elastic deformation, thereby achieving a reliable connection between the conductive rod 2 and the energy input device and effectively extending the service life of the medical conductive connection structure.

[0063] Since the elastic part is a conductive element 3, the elastic part can be manufactured and assembled separately, which makes it convenient to replace only the elastic part when it is damaged, and to retain the elastic part when the energy access part 1 is damaged. Therefore, in this embodiment, the elastic part is preferably a conductive element 3.

[0064] Furthermore, the conductive component 3 can be a metal component with good elastic deformation ability, such as a torsion spring. In this case, the installation channel is the channel inside the torsion spring. A reliable electrical connection between the conductive component 3 and the conductive rod 2 can be achieved by filling the inside of the torsion spring with a conductive layer.

[0065] Or, such as Figures 4-9 As shown, the conductive element 3 may only have a recessed portion 30 that deforms toward the direction away from the inner wall of the mounting hole 10, or as... Figures 10-15 As shown, the conductive element 3 has only a protrusion 31 that deforms in the direction away from the conductive rod 2. Alternatively, the conductive element 3 has both a recess 30 that deforms in the direction away from the inner wall of the mounting hole 10 and a protrusion 31 that deforms in the direction away from the conductive rod 2; wherein the bottom of the recess 30 abuts against the conductive rod 2, and the top of the protrusion 31 abuts against the inner wall of the mounting hole 10.

[0066] When the conductive component 3 is provided with a recessed portion 30 or a protruding portion 31, both the recessed portion 30 and the protruding portion 31 can realize the radial deformation capability of the conductive component 3, thereby further increasing the pressure of the conductive component 3 on the conductive rod 2 and further ensuring the installation stability and electrical connection stability of the conductive component 3.

[0067] When the conductive element 3 has both a recessed portion 30 and a protruding portion 31, the conductive element 3 can adopt a structure with a wavy surface, and such as Figure 4 , Figure 5 and Figure 6 As shown, when the conductive element 3 has only one recess 30 or as... Figure 10 , Figure 11 andFigure 12 As shown in FIG. 6, when only one protrusion 31 is arranged on the conductive member 3, the conductive member 3 can adopt a structure with an arc surface.

[0068] When the conductive member 3 is an elastic member and at least one of the recess 30 and the protrusion 31 is arranged on the conductive member 3, the conductive member 3 can also adopt a ring structure, and the side wall of the ring of the conductive member 3 is provided with at least one of the recess 30 and the protrusion 31. Alternatively, the conductive member 3 can be multiple and each conductive member 3 is in a sheet structure.

[0069] In addition, when the elastic part is formed by the side wall of the energy access member 1 located at the side of the mounting hole 10, the elastic part on the mounting hole 10 can be provided with a recess 30 deformed towards the direction away from the inner wall of the mounting hole 10; when the elastic part is formed by the circumferential side wall of the conductive rod 2 located in the mounting hole 10, the elastic part on the conductive rod 2 can be provided with a protrusion 31 deformed towards the direction away from the conductive rod 2; at this time, the bottom of the recess 30 also abuts against the conductive rod 2, and the top of the protrusion 31 also abuts against the inner wall of the mounting hole 10. In use, the recess 30 and the protrusion 31 can also realize the radial deformation ability of the elastic part, thereby further improving the pressure of the elastic part on the conductive rod 2 and further ensuring the stability of the electrical connection.

[0070] When the elastic part is formed by the side wall of the energy access member 1 located at the side of the mounting hole 10 or the circumferential side wall of the conductive rod 2 located in the mounting hole 10, the deformation seam 11 can be multiple, and the multiple deformation seams 11 are distributed along the circumference of the mounting hole 10 at equal intervals; or, when the elastic part is the conductive member 3, as shown in FIG. 7, the conductive member 3 can be multiple, and the multiple conductive members 3 are distributed along the circumference of the mounting hole 10 at equal intervals. Figures 7-9 、 Figures 13-15 As shown in FIG. 7, the conductive member 3 can be multiple, and the multiple conductive members 3 are distributed along the circumference of the mounting hole 10 at equal intervals.

[0071] The multiple conductive members 3 distributed along the circumference of the mounting hole 10 at equal intervals can improve the distribution balance of the conductive member 3, thereby further improving the stability of the conductive member 3 in the relative rotation process between the energy access member 1 and the conductive member 3.

[0072] As shown in FIG. 8 and FIG. 9, the conductive member 3 can be two, as shown in FIG. 10 and FIG. 11, Figure 7 and Figure 15 As shown in FIG. 12 and FIG. 13, the conductive member 3 can also be three. Figure 8 、 Figure 9 、 Figure 13 and Figure 14 As shown in FIG. 14 and FIG. 15, the conductive member 3 can also be three.

[0073] In order to effectively improve the use effect and use stability of the conductive member 3, the conductive member 3 is preferably at least three in the embodiment.

[0074] In the embodiment, when the conductive member 3 is multiple, as shown in FIG. 16 and FIG. 17, Figure 4 、 Figure 5 ,Figure 10 and Figure 12 As shown in FIGS. 1 and 2, the plurality of conductive members 3 can be arranged in a regular annular array around the central axis of the conductive rod 2, or as shown in FIGS. 3 and 4, the plurality of conductive members 3 can be arranged in an S-shaped staggered distribution along the circumference of the mounting hole 10. Figure 6 and Figure 11 As shown in FIGS. 3 and 4, when the conductive members 3 are provided with recesses 30, the side of each conductive member 3 close to the center of the mounting hole 10 is connected with the conductive rod 2, and the side of each conductive member 3 away from the center of the mounting hole 10 is connected with the inner wall of the mounting hole 10. Figure 6 As shown in FIGS. 3 and 4, when the conductive members 3 are provided with recesses 30, the side of each conductive member 3 close to the center of the mounting hole 10 is connected with the conductive rod 2, and the side of each conductive member 3 away from the center of the mounting hole 10 is connected with the inner wall of the mounting hole 10. Figure 11 As shown in FIGS. 3 and 4, when the conductive members 3 are provided with recesses 30, the side of each conductive member 3 close to the center of the mounting hole 10 is connected with the conductive rod 2, and the side of each conductive member 3 away from the center of the mounting hole 10 is connected with the inner wall of the mounting hole 10.

[0075] As shown in FIGS. 3 and 4, when the conductive members 3 are provided with recesses 30, the side of each conductive member 3 close to the center of the mounting hole 10 is connected with the conductive rod 2, and the side of each conductive member 3 away from the center of the mounting hole 10 is connected with the inner wall of the mounting hole 10. Figure 6 As shown in FIGS. 3 and 4, when the conductive members 3 are provided with recesses 30, the side of each conductive member 3 close to the center of the mounting hole 10 is connected with the conductive rod 2, and the side of each conductive member 3 away from the center of the mounting hole 10 is connected with the inner wall of the mounting hole 10. Figure 11 As shown in FIGS. 3 and 4, when the conductive members 3 are provided with recesses 30, the side of each conductive member 3 close to the center of the mounting hole 10 is connected with the conductive rod 2, and the side of each conductive member 3 away from the center of the mounting hole 10 is connected with the inner wall of the mounting hole 10.

[0076] In this embodiment, the side of the conductive member 3 close to the mounting hole 10 can be fixedly connected with the inner wall of the mounting hole 10, and the side of the conductive member 3 close to the conductive rod 2 can be in abutment with the conductive rod 2. The diameter of the mounting channel is smaller than the diameter of the conductive rod 2.

[0077] The fixed connection between the conductive member 3 and the inner wall of the mounting hole 10 can be achieved by welding, integral molding, embedding, etc.

[0078] When the conductive member 3 is fixedly connected with the inner wall of the mounting hole 10 and in abutment with the conductive rod 2, the installation stability of the conductive member 3 in the mounting hole 10 can be further improved, and when the conductive member 3 is an elastic member, the conductive rod 2 can be prevented from hindering the deformation of the diameter of the mounting channel during the process of the conductive rod 2 relative movement with the energy input member.

[0079] It should be noted that since the diameter of the mounting channel is smaller than the diameter of the conductive rod 2, the conductive rod 2 is in interference fit in the mounting channel. When the conductive member 3 is an elastic member, the elastic member can be ensured to have a pre-tightening force after being compressed, so that the conductive member 3 and the conductive rod 2 can always maintain reliable electrical connection when the conductive rod 2 moves relative to the energy input member.

[0080] Alternatively, the side of the conductive piece 3 close to the mounting hole 10 can be in abutment with the inner wall of the mounting hole 10, while the side of the conductive piece 3 close to the conductive rod 2 is fixedly connected with the conductive rod 2; along the radial direction of the mounting hole 10, the vertical distance between the side of the conductive piece 3 away from the conductive rod 2 and the central axis of the conductive rod 2 is greater than the radius of the mounting hole 10.

[0081] The fixed connection between the conductive piece 3 and the conductive rod 2 can also be achieved by welding, one-piece forming, embedding, etc.

[0082] When the conductive piece 3 is in abutment with the inner wall of the mounting hole 10 and the conductive piece 3 is fixedly connected with the conductive rod 2, the installation stability of the conductive piece 3 in the mounting hole 10 can be further improved, and the conductive rod 2 can be prevented from hindering the deformation process of the installation channel diameter when the conductive piece 3 is an elastic piece.

[0083] It should be noted that the vertical distance between the side of the conductive piece 3 away from the conductive rod 2 and the central axis of the conductive rod 2 along the radial direction of the mounting hole 10 is greater than the radius of the mounting hole 10, which can make the conductive rod 2 with the conductive piece 3 fixed thereon be in interference fit in the mounting hole 10. When the conductive piece 3 is an elastic piece, it can also ensure that the elastic piece continuously has pre-tightening force when it is compressed, so that the conductive piece 3 and the conductive rod 2 always maintain reliable electrical connection when the conductive rod 2 moves relative to the energy input piece.

[0084] As shown in FIG. 1, the medical conductive connection structure provided by the embodiment comprises an energy input piece 1, a conductive rod 2 and a conductive piece 3. Figure 1 As shown in FIG. 1, the medical conductive connection structure provided by the embodiment comprises an energy input piece 1, a conductive rod 2 and a conductive piece 3.

[0085] Among them, the mounting slot is used to provide mounting space for the energy input piece 1, and the through hole is used to provide space for the conductive rod 2.

[0086] The fixed seat 7 can not only provide support for the energy input piece 1 to ensure the installation stability of the energy input piece 1, but also can protect and insulate the peripheral side of the energy input piece 1.

[0087] In order to further improve the installation stability and assembly convenience of the energy input piece 1 on the fixed seat 7, the energy input piece 1 and the mounting slot are preferably in interference fit.

[0088] In addition, the inner wall of the mounting groove can be prismatic, and the energy access element 1 located in the mounting groove is also prismatic. In this way, after the energy access element 1 is installed in the mounting groove, the energy access element 1 and the mounting groove are in abutment through the prismatic side wall, so that the energy access element 1 is limited from rotating in the mounting groove, and the installation stability of the energy access element 1 in the mounting groove is further improved.

[0089] As shown in Figure 2 and Figure 3 , the inner wall of the mounting hole 10 is provided with a first step portion 100 and a second step portion 101 which are spaced apart along the axial direction, and the conductive element 3 is in abutment between the first step portion 100 and the second step portion 101. The first step portion 100 and the second step portion 101 can cooperate with each other to limit the conductive element 3, so as to improve the installation stability and use stability of the conductive element 3 in the mounting hole.

[0090] Further, one end of the fixed seat 7 can be connected with a handle 8, and the end face of the handle 8 close to the fixed seat 7 forms the first step portion 100 on one side of the through hole; the second step portion 101 is arranged at a position of the inner wall of the mounting hole 10 away from the handle 8, one end of the conductive element 3 close to the handle 8 extends to the first step portion 100 and is in abutment with the first step portion 100, and the other end of the conductive element 3 is in abutment with the second step portion 101.

[0091] In this way, the length of the conductive element 3 can be extended to improve the use effect, and the assembly convenience of the conductive element 3 can be improved. Specifically, when the conductive element 3 is assembled into the mounting hole 10, only one end of the conductive element 3 needs to be inserted into the through hole and the mounting hole 10 from one end of the fixed seat 7 before the handle 8 is connected to one end of the fixed seat 7, until the end of the conductive element 3 is in abutment with the second step portion 101. Then, the handle 8 is connected to the end of the fixed seat 7 away from the second step portion 101. After the handle 8 and the fixed seat 7 are connected to each other, the first step portion 100 is formed, and the first step portion 100 is in abutment with the end of the conductive element 3 away from the second step portion 101. Thus, the assembly process of the conductive element 3 is completed.

[0092] In addition, the handle 8 is usually a structure inherent to the electrosurgical equipment. In this embodiment, the first step portion 100 is formed by using the inherent structure of the handle 8, so that the formation process of the first step portion 100 can be effectively simplified without additional processing.

[0093] As shown in Figure 2 , the handle 8 is usually provided with a rod passing hole through which the conductive rod 2 passes, and the rod passing hole is in communication with the through hole. At this time, in order to make the end face of the end of the handle 8 close to the fixed seat 7 still form the first step portion 100 on one side of the through hole, the diameter of the rod passing hole needs to be smaller than the diameter of the through hole.

[0094] AsFigure 1 As shown, the electrosurgical apparatus provided by the embodiment comprises the medical conductive connection structure, because the electrosurgical apparatus and the medical conductive connection structure can solve the same technical problems and achieve the same technical effects, and thus will not be described herein.

[0095] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
