Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a surgical instrument for removing the sympathetic nerves of the renal artery. Background Art

[0002] Interventional cardiovascular technology is commonly used to treat hypertension by interrupting the activity of the afferent and efferent renal sympathetic nerves through the application of radiofrequency energy, ultrasound energy, or injection of heat into the perivascular space. This affects the sympathetic nerves around the renal arteries, reduces the stimulation of the sympathetic nervous system on the kidneys, and thus achieves the therapeutic goal of lowering blood pressure.

[0003] Interventional vascular treatments using renal artery denervation forceps and other instruments are a common method. However, these forceps can easily over-compress the blood vessels, compromising surgical safety, or fail to adhere properly to the vessels, impacting surgical efficiency. Summary of the Invention

[0004] The present application provides a surgical instrument for removing the sympathetic nerves of the renal artery, which can not only achieve good fit between the surgical instrument and the blood vessel, but also reduce the risk of excessive compression of the blood vessel by the surgical instrument, thereby improving the efficiency and safety of the operation.

[0005] In one aspect, the present application provides a surgical instrument for renal artery sympathetic denervation, comprising: an operating assembly, a connecting assembly, and a clamping assembly. The operating assembly is connected to one end of the connecting assembly; two sets of clamping assemblies are movably connected to the end of the connecting assembly distal from the operating assembly, with the clamping surface of each clamping assembly matching the shape of the surgical object. When the operating assembly drives the connecting assembly to move, such that the connecting assembly brings the two clamping assemblies closer together, the clamping surfaces of the two clamping assemblies enclose each other to form a clamping space.

[0006] The surgical instrument for renal artery sympathetic denervation provided herein connects a clamping assembly and an operating assembly via a connecting assembly, with the clamping assembly movably mounted on the connecting assembly. This facilitates the clamping assembly to clamp and adhere to the surgical object through manipulation of the operating assembly. Furthermore, the clamping surface of the clamping assembly is configured to match the external shape of the surgical object. During adhesion, this surface increases the contact area between the clamping surface and the surgical object, facilitating efficient energy transfer to the surgical object through the clamping surface. Furthermore, when the two clamping assemblies are brought into close proximity to clamp the surgical object, the clamping surfaces enclose a clamping space, creating a space that accommodates the surgical object, thereby reducing the compressive force exerted by the clamping surfaces on the surgical object. Therefore, during surgery, the surgical instrument for renal artery sympathetic denervation provided herein can achieve good adhesion between the surgical instrument and the blood vessel while reducing the risk of excessive pressure on the blood vessel, thereby improving surgical efficiency and safety.

The clamping part also has a wire channel, and at least a portion of the wire channel is connected and overlaps with at least a portion of the perfusion main line.

[0014] In one possible implementation of the present application, the clamping member has a wire channel, which passes through the connecting portion and extends to the clamping portion, and extends from the clamping portion to the position of the electrode member, and the wire channel is used to pass the wire.

[0018] In a possible implementation of the present application, the clamping portion has a receiving groove matching the electrode member, and the electrode member is disposed in the receiving groove.

[0019] In one possible implementation of the present application, one of the clamping portion and the electrode member has a positioning post, and the other of the clamping portion and the electrode member has a positioning hole matching the positioning post. The positioning post or the positioning hole extends from the bottom of the accommodating groove, and the positioning post cooperates with the positioning hole to limit the position of the electrode member relative to the clamping portion.

DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0035] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0036] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0037] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0038] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0040] Hypertension is a major risk factor for cardiovascular disease, and increased sympathetic nervous system activity is a key factor in the pathophysiology of hypertension. Renal artery sympathetic nerve ablation (RDN) is a percutaneous interventional treatment that uses radiofrequency, ultrasound, and other energies to eliminate afferent and efferent renal artery nerves, partially blocking signal transmission between the brain and sympathetic nerves. This reduces sympathetic nerve excitability in hypertensive patients, achieving long-term, stable blood pressure reduction with a single minimally invasive procedure.

[0041] Compared with interventional radiofrequency RDN, the combination of mature laparoscopic technology and radiofrequency ablation technology to design a surgical RDN ablation system based on laparoscopic technology has at least the following advantages: (1) reducing the direct damage of radiofrequency energy to the renal artery intima, reducing the risk of thrombosis and secondary renal artery stenosis (because the sympathetic nerves are mainly distributed in the renal artery adventitia); (2) achieving more thorough ablation; and (3) meeting the ablation requirements of renal arteries of various sizes.

[0042] In the related art, the surgical forceps for removing the renal artery sympathetic nerves are provided. During the implementation of RDN, the surgical forceps for removing the renal artery sympathetic nerves are prone to excessive compression of the blood vessels, affecting the safety of the operation, or the surgical forceps cannot fit well with the blood vessels, affecting the efficiency of the operation.

[0043] The present invention provides a surgical instrument for removing the renal artery sympathetic nerves, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Figure 1 Schematic diagram of the structure of the surgical instrument for removing the renal artery sympathetic nerve provided in this application Figure 1 , Figure 2 Schematic diagram of the structure of the surgical instrument for removing the renal artery sympathetic nerve provided in this application Figure 2 , Figure 3 Schematic diagram of the structure of the clamp in the surgical instrument for removing the renal artery sympathetic nerve provided in this application Figure 1 , Figure 4 Provided for this application Figure 3 Cross-sectional view along AA direction.

[0044] The surgical instrument for renal artery sympathetic denervation provided in the present embodiment comprises: an operating assembly (not shown), a connecting assembly 1, and a clamping assembly 2. The operating assembly is connected to one end of the connecting assembly 1; two sets of clamping assemblies 2 are movably connected to the end of the connecting assembly 1 away from the operating assembly. The clamping surface of each set of clamping assemblies 2 matches the shape of the surgical object. After the operating assembly drives the connecting assembly 1 to move, so that the connecting assembly 1 drives the two sets of clamping assemblies 2 toward each other, the clamping surfaces of the two sets of clamping assemblies 2 enclose each other to form a clamping space 23.

[0045] In the embodiment of the present application, the operating assembly is used to hold and manipulate surgical instruments. The operating assembly can be configured to include a fixed handle and a movable handle. The fixed handle can be fixed to the connecting assembly 1, and the movable handle can be hinged and rotated to a position corresponding to the fixed handle on the connecting assembly 1. The user can hold the fixed handle and the movable handle and drive the movable handle to rotate relative to the connecting assembly 1, thereby driving the connecting assembly 1 to move.

[0046] In the embodiment of the present application, the connecting component 1 is used to provide an installation basis for the operating component and the clamping component 2, and to transmission-connect the operating component with the clamping component 2 to enable operation of the clamping component 2 through the operating component.

[0047] Exemplarily, the connecting component 1 can be set to a structure including an outer tube 11 and an inner tube 12, the inner tube 12 can be inserted into the outer tube 11, a part of each group of clamping components 2 is rotatably connected to the outer tube 11, one end of the inner tube 12 is connected to the operating component, and the other end of the inner tube 12 is connected to each group of clamping components 2 through a transmission, so that when the operating component drives the inner tube 12 to move relative to the outer tube 11, the inner tube 12 can drive the clamping component 2 to rotate relative to the outer tube 11.

[0048] As another example, the outer tube 11 can be set to a cylindrical shape, and the inner tube 12 can be set to a cylindrical shape with an outer diameter smaller than the inner diameter of the outer tube 11. The inner tube 12 can be inserted into the outer tube 11 so that the inner tube 12 can slide inside the outer tube 11. For example, the fixed handle can be fixedly connected to the outer tube 11, the movable handle can be rotatably connected to the outer tube 11, and the movable handle can be connected to the inner tube 12 by a pull rod or the like. Then, in the process of operating the movable handle to rotate relative to the outer tube 11, the movable handle can drive the inner tube 12 to move relative to the outer tube 11 along the pulling direction Z. The pulling direction Z is also the axial direction of the connecting component 1, and can also be understood as the arrangement direction of the connecting component 1 and the clamping component 2.

[0049] Another example, such as Figure 4As shown, a first connecting hole 215 can be set on the clamping member 21 in each group of clamping assemblies 2, and correspondingly, a third connecting hole corresponding to the first connecting hole 215 can be set at the distal end of the outer tube 11. A fixed shaft matching both the first connecting hole 215 and the third connecting hole can be used, and the fixed shaft can be passed through the first connecting hole 215 and the third connecting hole, so that both clamping members 21 can be rotated and set at the distal end of the outer tube 11.

[0050] It should be noted that the distal end described in the embodiments of the present application refers to the end of the surgical instrument for renal artery sympathetic denervation that is away from the operating handle along the pulling direction Z, and the proximal end refers to the end of the surgical instrument for renal artery sympathetic denervation that is closer to the operating handle along the pulling direction Z. For example, the distal end of the clamping assembly 2 is the end of the clamping assembly 2 that is away from the operating handle along the pulling direction Z, and the proximal end of the clamping assembly is the end of the clamping assembly 2 that is closer to the operating handle along the pulling direction Z.

[0051] Another example, such as Figure 4 As shown, a second connection hole 216 can be provided on the clamping member 21 in each group of clamping assemblies 2, and the second connection hole 216 is closer to the connection assembly 1 than the first connection hole 215 along the pulling direction Z. Figure 1 As shown, a first connecting shaft can be provided at the distal end of the inner tube 12. The inner tube 12 and the clamping member 21 can be connected by transmission via the connecting rod 13, that is, a fourth connecting hole matching the first connecting shaft is provided at the proximal end of the connecting rod 13, thereby hingedly connecting the connecting rod 13 and the inner tube 12 via the connecting shaft and the fourth connecting hole. A second connecting shaft matching the second connecting hole 216 can be provided at the distal end of the connecting rod 13, thereby hingedly connecting the connecting rod 13 and the clamping member 21 via the second connecting shaft and the second connecting hole 216. In this way, when the movable handle drives the inner tube 12 to move relative to the outer tube 11 along the pulling direction Z, the inner tube 12 can drive the connecting rod 13 to move, and the connecting rod 13 can apply a pulling force or a pushing force along the pulling direction Z to the clamping member 21, thereby causing the two groups of clamping assemblies 2 to rotate relative to the connecting assembly 1.

[0052] In the embodiment of the present application, the clamping assembly 2 is used to clamp the surgical object (such as blood vessel tissue, nerve tissue), and apply energy to the surgical object to eliminate the surgical object. Figure 1 and Figure 2 As shown, the two clamping assemblies 2 can be moved relative to each other by the operating assembly and the connecting assembly 1 to form a clamping space 23 with a larger opening. This allows a portion of each clamping assembly 2 to pass through both sides of the surgical object and surround the surgical object. The operating assembly can then be operated to bring the two clamping assemblies 2 closer together (the distal ends of the two clamping assemblies 2 can abut against each other) to form a clamping space 23 with a smaller opening. This allows both clamping assemblies 2 to fit the surgical object.

[0053] For example, the portion of the clamping assembly 2 used to clamp the surgical object (e.g., a blood vessel) can be configured to match the shape of the surgical object. For example, the portion of the clamping assembly 2 that clamps the blood vessel can be configured as an arc structure. Thus, two semicircular clamping assemblies 2 can enclose a substantially circular clamping space 23, thereby allowing the clamping assembly 2 to conform to the outer circumference of the substantially cylindrical blood vessel.

[0054] As another example, the portion of the clamping assembly 2 used to clamp the surgical object (such as a blood vessel) can be set as an arc-shaped structure, and the arc-shaped structure can be understood as a continuous and smoothly curved structure. For example, the arc-shaped structure can be a section of an arc bar, or it can be an arc bar formed by connecting at least two sections of arc bars with the same or different radii in sequence. In this way, the surface of the arc-shaped structure facing the clamping space 23 can be used as a clamping surface, and the clamping surface is a smooth arc-shaped surface, which is formed by continuous and smooth curvature along the pulling direction Z. In this way, regardless of whether the shape of the blood vessel is approximately cylindrical or flat elliptical, the clamping surfaces of the two arc-shaped structures can fit more of the outer surface of the blood vessel.

[0055] The surgical instrument for renal artery sympathetic denervation provided in the embodiments of the present application connects the clamping assembly 2 and the operating assembly via the connecting assembly 1, and the clamping assembly 2 is movably mounted on the connecting assembly 1. This facilitates the clamping assembly 2 to clamp the surgical object and conform to the surgical object by operating the operating assembly. Furthermore, the clamping surface of the clamping assembly 2 is configured to match the outer shape of the surgical object. During conformation, this clamping surface increases the contact area between the clamping surface and the surgical object, facilitating efficient energy transfer to the surgical object through the clamping surface. Furthermore, when the two sets of clamping assemblies 2 are brought into close proximity to clamp the surgical object, the clamping surfaces enclose a clamping space 23, creating a space to accommodate the surgical object, thereby reducing the pressure exerted by the clamping surfaces on the surgical object. Therefore, during surgery, the surgical instrument for renal artery sympathetic denervation provided in the embodiments of the present application can achieve good conformation between the surgical instrument and the blood vessel while reducing the risk of excessive pressure on the blood vessel by the surgical instrument, thereby improving the efficiency and safety of the surgery.

[0056] In some possible embodiments of the present application, Figure 2 As shown, when the distal ends of the two groups of clamping components 2 abut against each other, the clamping space 23 is spindle-shaped.

[0057] In the embodiment of the present application, the structural shape of the clamping assembly 2 can be set so that when two groups of clamping assemblies 2 approach each other until they abut against each other, the space enclosed by the clamping surfaces of the two groups of clamping assemblies 2 is spindle-shaped.

[0058] For example, the portion of the clamping assembly 2 that clamps the surgical object can be an arc-shaped structure, and the radius of the arc-shaped structure of each set of clamping assemblies 2 is greater than the maximum distance of the clamping space 23 (when the distal ends of the two sets of clamping assemblies 2 are in contact) along the clamping direction Y, wherein the clamping direction Y is perpendicular to the pulling direction Z, and the clamping direction Y is the direction in which the two sets of clamping assemblies 2 move closer to or farther from each other. Figure 2 As shown, along the pulling direction Z, with the maximum cross section ( Figure 2 When the clamping space 23 is divided into two parts (a plane where the single dotted line is located), the two parts are approximately triangular prisms (two side surfaces of the triangular prism are arc-shaped surfaces, and one side surface is a plane).

[0059] In the above embodiment, since the distal ends of the two groups of clamping components 2 are abutted, the clamping space 23 is spindle-shaped. In this way, when clamping a surgical object, such as clamping a blood vessel, the spindle-shaped clamping space 23 can match a wider range of blood vessel outer diameter sizes, which is conducive to forming a good fit between the clamping surface and the blood vessel, thereby improving the effectiveness of the operation.

[0060] In some possible embodiments of the present application, refer to Figure 5 and Figure 6 , Figure 5 Schematic diagram of the structure of the electrode component in the surgical instrument for removing the renal artery sympathetic nerve provided in this application Figure 1 , Figure 6 Provided for this application Figure 5 The cross-sectional view along the BB direction. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the clamping assembly 2 includes a clamping member 21 and an electrode member 22; the clamping member 21 includes a connecting portion 211 and a clamping portion 212; the connecting portion 211 is movably connected to the connecting assembly 1, and the side of the clamping portion 212 facing the clamping space 23 is a first clamping surface 217, and the electrode member 22 is arranged at the position where the first clamping surface 217 is located on the clamping portion 212, and the side of the electrode member 22 facing the clamping space 23 is an electrode clamping surface 224, and the electrode clamping surface 224 and the first clamping surface 217 together form a clamping surface.

[0061] In an embodiment of the present application, the clamping assembly 2 can be configured to include a clamping member 21 and an electrode member 22, so that energy is applied to the surgical object via the electrode member 22, while the clamping member 21 supports the electrode member 22 and drives the movement of the electrode member 22. For example, the clamping member 21 can be made of an insulating material such as plastic or rubber, and the electrode member 22 can be a radiofrequency ablation electrode, a microwave ablation electrode, etc. When radiofrequency current or microwave energy is applied to the electrode member 22, the electrode member 22 can generate heat, which acts on the tissue of the surgical object to achieve the purpose of treatment. The embodiments of the present application do not limit the specific materials of the clamping member 21 and the electrode member 22.

[0062] In the embodiment of this application, Figure 3 and Figure 4 As shown, the clamping member 21 can be configured to include a connecting portion 211 and a clamping portion 212. For example, the connecting portion 211 and the clamping portion 212 can be configured to Figure 3 and Figure 4 The dashed line extending along the clamping direction Y shown in FIG is the dividing line. It should be noted that this division is merely an example, and other dividing lines may be used to divide the connecting portion 211 and the clamping portion 212. A first connecting hole 215 and a second connecting hole 216 may be provided on the connecting portion 211, so that the clamping member 21 can be rotatably connected to the outer tube 11 through the first connecting hole 215 and the clamping member 21 can be rotatably connected to the connecting rod 13 through the second connecting hole 216, thereby achieving a movable connection between the clamping assembly 2 and the connecting assembly 1.

[0063] For example, Figure 3 and Figure 4 As shown, the clamping portion 212 of the clamping member 21 can be configured as an arc-shaped strip, that is, the entire clamping portion 212 is arc-shaped and has a strip-like structure. For example, the clamping portion 212 can be configured as an arc-shaped strip with a central angle corresponding to the arc length ranging from 100° to 140°, such as the clamping portion 212 being configured as an arc-shaped strip with a central angle corresponding to the arc length of 120°. The side of the clamping portion 212 facing the clamping space 23 is a first clamping surface 217, which is a smooth and continuous arc-shaped curved surface.

[0064] In the embodiment of this application, Figure 5 and Figure 6As shown, the electrode member 22 can be configured as an arc-shaped strip that matches the clamping portion 212, that is, the degree of curvature of the electrode member 22 is consistent or nearly consistent with the degree of curvature of the clamping portion 212. For example, the electrode member 22 can be configured as an arc-shaped strip with a central angle corresponding to the arc length ranging from 80° to 100°, such as the electrode member 22 can be configured as an arc-shaped strip with a central angle corresponding to the arc length of 90°. The surface of the electrode member 22 facing the clamping space 23 is an electrode clamping surface 224, and the electrode clamping surface 224 is a smooth, continuous, and gradually curved arc surface.

[0065] For example, the first clamping surface 217 and the electrode clamping surface 224 can be two arcuate surfaces with the same structure, that is, the electrode clamping surface 224 bends and extends in the same manner as the first clamping surface 217, so that the electrode clamping surface 224 and the first clamping surface 217 can be completely aligned. In this way, when the two electrode members 22 approach each other along the clamping direction Y, the distance between the distal vertices 223 of the two electrode members 22 is smaller than the distance between the proximal vertices 222 of the two electrode members 22. This type of electrode member 22 with a gradually curved electrode clamping surface 224 can effectively fit blood vessels with a wider range of outer diameters.

[0066] For example, Figure 3 and Figure 4 As shown, a receiving groove 213 matching the electrode member 22 can be provided on the clamping portion 212, so that the electrode member 22 can be installed on the clamping portion 212 through the receiving groove 213. For example, the receiving groove 213 can be an arc-shaped groove that is recessed from the first clamping surface 217 in a direction away from the clamping space 23, and the depth of the arc-shaped groove is the same as the thickness of the electrode member 22, so that the electrode member 22 can be accommodated in the arc-shaped groove. At this time, the electrode clamping surface 224 and the first clamping surface 217 overlap to form a complete clamping surface. Since the electrode member 22 is located in the receiving groove 213, the reliability of the electrode member 22 being installed on the clamping member 21 can be improved.

[0067] Another example, such as Figure 4 and Figure 6As shown, a positioning structure can be provided on the clamping portion 212 and the electrode member 22. For example, a positioning hole 214 can be provided on the clamping portion 212, and the positioning hole 214 extends from the bottom of the accommodating groove 213 in a direction away from the clamping space 23, so that the positioning hole 214 can pass through the bottom of the accommodating groove 213. Correspondingly, a positioning post 221 matching the positioning hole 214 can be provided on the side of the electrode member 22 away from the electrode clamping surface 224. Alternatively, a positioning post 221 can be provided at the bottom of the accommodating groove 213 on the clamping portion 212, and the positioning post 221 extends from the bottom of the accommodating groove 213 in a direction close to the clamping space 23. Correspondingly, a positioning hole 214 matching the positioning post 221 can be provided on the side of the electrode member 22 away from the electrode clamping surface 224.

[0068] In this way, during the process of installing the electrode member 22 on the clamping member 21, the positioning column 221 can be inserted into the positioning hole 214 to limit the relative position of the electrode member 22 and the clamping portion 212, which is beneficial to improving the assembly efficiency and assembly accuracy of the electrode member 22 and the clamping portion 212.

[0069] In the above embodiment, since the clamping member 21 includes the connecting portion 211 and the clamping portion 212, the clamping member 21 can be movably connected to the connecting assembly 1 via the connecting portion 211, and the electrode member 22 can be easily installed via the clamping portion 212. Furthermore, the electrode clamping surface 224 and the first clamping surface 217 together form a clamping surface, which can be made into a smooth and continuous arc-shaped surface, thereby reducing protrusions on the clamping surface, thereby reducing the risk of the surgical instrument scratching the surgical object during use, and improving the safety of the surgical instrument.

[0070] In some possible embodiments of the present application, Figure 3 and Figure 4 As shown, the clamping assembly 2 has a perfusion channel 3, which extends from the connecting portion 211 to the first clamping surface 217 and / or the electrode clamping surface 224, and is used for conveying liquid.

[0071] In the embodiment of the present application, an irrigation channel 3 may be provided on the clamping assembly 2 . For example, the irrigation channel 3 may be a circular hole-shaped channel for delivering liquid to the surgical object through the irrigation channel 3 . The liquid may be physiological saline or the like.

[0072] For example, the perfusion channel 3 can be provided on the clamping member 21, or can be provided on the clamping member 21 and the electrode member 22. For example, the perfusion channel 3 can be provided through the connecting portion 211 and the clamping portion 212 along the pulling direction Z, wherein the perfusion inlet of the perfusion channel 3 on the connecting portion 211 is located at the proximal end of the connecting portion 211, and the perfusion outlet of the perfusion channel 3 on the clamping portion 212 is located at the proximal end of the clamping portion 212, that is, the perfusion outlet is located in an area on the first clamping surface 217 near the connecting portion 211. Multiple perfusion channels 3 can be provided on the clamping assembly 2.

[0073] In another example, the perfusion channel 3 may also pass through the connecting portion 211 , the clamping portion 212 and the electrode member 22 in sequence along a direction forming an angle with the pulling direction Z. In this case, the perfusion outlet is located on the electrode clamping surface 224 of the electrode member 22 .

[0074] As another example, a connection structure matching the perfusion tube 8 can be provided at the perfusion inlet, such as a threaded interface, a snap-on interface, etc., so as to quickly and seal the perfusion tube 8 with the perfusion channel 3 through the connection structure.

[0075] In the above embodiment, since the clamping assembly 2 has the perfusion channel 3 and the perfusion channel 3 extends to the first clamping surface 217 and / or the electrode clamping surface 224, during a surgical procedure using the surgical instrument for renal artery sympathetic denervation provided in the embodiment of the present application, liquid can be delivered to the contact portion between the clamping surface and the surgical object through the perfusion channel 3. This allows the contact surface between the electrode clamping surface 224 and the surgical object to be flushed with the liquid, thereby effectively reducing the occurrence of a sharp increase in the temperature of the surgical object surface. In addition, the flowing liquid can promptly remove scabs formed on the surgical object surface due to overheating, thereby improving the safety of the surgery.

[0077] In some possible embodiments of the present application, Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the perfusion channel 3 includes a perfusion main line 31 and a perfusion branch line 32. The perfusion main line 31 extends from the connecting portion 211 to the electrode member 22. The perfusion branch line 32 is arranged on the electrode member 22 along the clamping direction Y of the clamping assembly 2, and the perfusion branch line 32 passes through the electrode clamping surface 224 to connect the perfusion main line 31 and the clamping space 23.

[0078] In the embodiment of the present application, the perfusion channel 3 can be provided with a structure including a connected perfusion main channel 31 and a perfusion branch channel 32. For example, a portion of the perfusion main channel 31 can be located on the clamping member 21, that is, a portion of the perfusion main channel 31 sequentially passes through the connecting portion 211 and the clamping portion 212 along the pulling direction Z, and the distal end of the perfusion main channel 31 can be located on the side wall of the accommodating groove 213 (the wall surface at the proximal end of the accommodating groove 213) on the clamping member 21. Correspondingly, as shown in FIG. Figure 10 As shown, another portion of the perfusion main channel 31 can be located on the electrode member 22, that is, another portion of the perfusion main channel 31 is disposed within the electrode member 22 along the pulling direction Z. The perfusion main channel 31 on the electrode member 22 can be a blind hole structure. The proximal end of the perfusion main channel 31 on the electrode member 22 can correspond to the distal end of the perfusion main channel 31 on the clamping portion 212. After the electrode member 22 is installed in the accommodating groove 213, the perfusion main channel 31 on the electrode member 22 and the perfusion main channel 31 on the clamping member 21 are connected and communicated to form a complete perfusion main channel 31.

[0079] For example, an irrigation branch 32 can be provided on the electrode member 22, and the irrigation branch 32 can extend along the clamping direction Y on the electrode member 22, that is, the irrigation branch 32 and the irrigation main channel 31 can be perpendicular to each other. One end of the irrigation branch 32 can be located on the electrode clamping surface 224, and the other end of the irrigation branch 32 can be connected to the irrigation main channel 31 in the electrode member 22.

[0080] In another example, a plurality of perfusion branches 32 may be provided on the electrode member 22, and the plurality of perfusion branches 32 may be provided along the axial direction of the electrode member 22 (eg Figure 10) are distributed on the electrode member 22 in sequence, and each perfusion branch 32 is connected to the perfusion main channel 31. For example, the number of perfusion branches 32 can be set according to the length of the electrode member 22, such as three perfusion branches 32 are set on the electrode member 22, and the three perfusion branches 32 can also extend along the radial direction of the electrode member 22 to penetrate the electrode clamping surface 224. It is also possible to set two perfusion branches 32, four perfusion branches 32, five perfusion branches 32, etc. perfusion branches 32 on the electrode member 22. The embodiment of the present application does not limit the specific number of perfusion branches 32. The multiple perfusion branches 32 can be evenly distributed on the electrode member 22 along the axial direction of the electrode member 22, that is, the distance between the perfusion outlets of two adjacent perfusion branches 32 is equal.

[0081] Another example, such as Figure 7 As shown, a wire channel 4 can be provided on the clamping member 21 to pass a wire through the wire channel 4. For example, a wire channel 4 can be provided on the clamping member 21 to be parallel to the perfusion trunk 31. In this case, the wire channel 4 and the perfusion trunk 31 are two independent through-hole structures. The wire channel 4 on the clamping member 21 can also be connected and overlapped with at least a portion of the perfusion trunk 31 on the clamping member 21. For example, the perfusion trunk 31 on the clamping member 21 and the wire channel 4 can be provided as an integral structure, that is, the aperture of the perfusion trunk 31 or the wire channel 4 on the clamping member 21 can be increased so that the perfusion trunk 31 (wire channel 4) on the clamping member 21 can not only transport a sufficient amount of liquid, but also accommodate the wire 7 electrically connected to the electrode member 22, etc. Thus, a wire 7 can be further provided in the irrigation main channel 31 on the clamping member 21 that sequentially passes through the connecting portion 211 and the clamping portion 212. In this case, the portion of the irrigation main channel 31 on the clamping member 21 can be sequentially passed through the connecting portion 211 and the clamping portion 212 along the pulling direction Z, and this portion of the irrigation main channel 31 can be extended to the location of the electrode member 22. This structural arrangement can reduce the number of channels provided in the clamping member 21, which is conducive to reducing the production cost of the clamping assembly 2.

[0082] As another example, a perfusion tube 8 channel can be set in the connecting component 1, for example, a perfusion tube 8 channel can be set inside the inner tube 12, and the perfusion tube 8 can be set inside the inner tube 12 so that the perfusion tube 8 extends through the inner tube 12 to the proximal end of the clamp 21.

[0083] In the above embodiment, since the irrigation channel 3 includes an irrigation main channel 31 and an irrigation branch channel 32, the position and number of the irrigation branch channels 32 on the electrode member 22 can be adjusted to provide an open irrigation outlet on the electrode clamping surface 224. This allows liquid to be directly delivered between the electrode clamping surface 224 and the surface of the surgical object, thereby reducing the time that the electrode clamping surface 224 is in contact with the surface of the surgical object for a prolonged period of time, thereby reducing the risk of overheating of the electrode clamping surface 224. Liquid can also be directly applied to the surface of the surgical object, directly flushing scabs formed on the surface of the surgical object due to overheating, thereby causing the scabs to fall off quickly and be carried away by the liquid.

[0084] In some possible embodiments of the present application, Figure 4 and Figure 7 As shown, the clamping member 21 has a wire channel 4, which passes through the connecting portion 211 and extends to the clamping portion 212, and extends from the clamping portion 212 to the position of the electrode member 22. The wire channel 4 is used to pass the wire 7.

[0085] In the embodiment of the present application, a wire channel 4 may be provided on the clamping member 21 , and a wire 7 may be provided through the wire channel 4 , so as to electrically connect the electrode member 22 to a radio frequency transmitter or a microwave generator.

[0086] For example, the wire channel 4 can be extended from the proximal end of the connecting portion 211 to the proximal end of the clamping portion 212 along the pulling direction Z, and the wire channel 4 can penetrate the connecting portion 211 and the clamping portion 212. For example, the distal end of the wire channel 4 can be located on the side wall of the accommodating groove 213 at the proximal end of the clamping portion 212. Then, after the electrode member 22 is placed in the accommodating groove 213, the wire 7 can be inserted into the wire channel 4 from the proximal end of the electrode member 22. The aperture of the wire channel 4 can be set according to the number and diameter of the wires 7 to be placed on the clamping assembly 2 as needed, and multiple wires 7 can be placed in the same wire channel 4 on the clamping member 21.

[0087] In another example, a wire channel 4 may be provided in the connection assembly 1 , for example, a wire channel 4 may be provided inside the inner tube 12 , and the wire 7 may be provided inside the inner tube 12 so that the wire 7 extends through the inner tube 12 to the proximal end of the clamp 21 .

[0088] In the above embodiment, since the clamping member 21 has a wire channel 4 extending from the clamping portion 212 to the location of the electrode member 22, the wire 7 can be extended through the wire channel 4 to the electrode member 22, thereby facilitating electrical connection between the electrode member 22 and the wire 7. Furthermore, the wire channel 4 is located within the clamping member 21, concealing the wire 7 within the clamping member 21. This allows the clamping assembly 2 to maintain a neat appearance, thereby minimizing the impact of the wire 7 on the surgical procedure.

[0089] In some possible embodiments of the present application, Figure 5 and Figure 6 As shown, the electrode member 22 has a first accommodating cavity 5 , which is communicated with the wire channel 4 . The first accommodating cavity 5 matches the temperature detecting member and is used to accommodate the temperature detecting member.

[0090] In an embodiment of the present application, a temperature detector can be provided in a surgical instrument for renal artery sympathetic denervation. For example, the temperature detector can be a thermistor or a thermocouple. A first accommodating cavity 5 that matches the temperature detector can be provided in the clamping assembly 2, allowing the temperature detector to be placed therein. Multiple first accommodating cavities 5 can be provided on the electrode member 22.

[0091] For example, a first accommodating cavity 5 can be provided on the electrode member 22. The shape of the first accommodating cavity 5 can be designed according to the shape of the temperature detection member. For example, the first accommodating cavity 5 can be provided in the shape of a circular hole. That is, a blind hole serving as the first accommodating cavity 5 can be provided at the proximal end of the electrode member 22. The blind hole can be provided at the proximal end of the electrode member 22 along the pulling direction Z. The first accommodating cavity 5 can also be connected to the wire channel 4 on the clamping member 21. In this way, after the temperature detection member is provided in the first accommodating cavity 5, the wire 7 connected to the temperature detection member can be passed through the wire channel 4 on the clamping member 21.

[0092] In the above embodiment, since the electrode member 22 has a first accommodating cavity 5 that matches the temperature detection element, the temperature detection element can be installed in the first accommodating cavity 5. Thus, when performing a surgical procedure using the renal artery sympathetic denervation surgical instrument provided in the embodiment of the present application, the temperature of the electrode member 22 itself can be promptly detected through the temperature detection element, thereby improving the accuracy of temperature control of the electrode member 22 and facilitating improved surgical safety. Furthermore, the first accommodating cavity 5 is connected to the wire channel 4, facilitating the installation of a wire 7 electrically connected to the temperature detection element within the clamping assembly 2.

[0093] In some possible embodiments of the present application, Figure 8 、 Figure 9 and Figure 10 As shown, the electrode member 22 has a second accommodating cavity 6 , which is communicated with the wire channel 4 . The second accommodating cavity 6 matches the pressure detection member and is used to accommodate the pressure detection member.

[0094] In the embodiment of the present application, a pressure detection element can be provided in the surgical instrument for renal artery sympathetic denervation. For example, the pressure detection element can be a strain gauge pressure sensor, a piezoresistive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, etc. A second accommodating cavity 6 that matches the pressure detection element can be provided in the clamping assembly 2, so that the pressure detection element can be provided through the second accommodating cavity 6. Multiple second accommodating cavities 6 can be provided on the electrode member 22.

[0095] For example, a second accommodating cavity 6 can be provided on the electrode member 22. The shape of the second accommodating cavity 6 can be designed according to the shape of the pressure detection member. For example, the second accommodating cavity 6 can be provided as a circular hole, a square hole, a polygonal hole, etc. That is, a blind hole serving as the second accommodating cavity 6 can be provided at the proximal end of the electrode member 22. The blind hole can be provided at the proximal end of the electrode member 22 along the pulling direction Z. The second accommodating cavity 6 can also be connected to the wire channel 4 on the clamping member 21. In this way, after the pressure detection member is disposed in the second accommodating cavity 6, the wire 7 connected to the pressure detection member can be passed through the wire channel 4 on the clamping member 21.

[0096] In the above embodiment, since the electrode member 22 has a second accommodating cavity 6 that matches the pressure detection element, a temperature detection element can be disposed in the second accommodating cavity 6. Thus, when performing surgery using the renal artery sympathetic denervation surgical instrument provided in the embodiment of the present application, the pressure changes of the electrode member 22 can be detected in real time through the pressure detection element, and the magnitude of the pressure applied to the surgical object by the electrode member 22 can also be detected. This can reduce the risk of vascular stenosis of the surgical object (e.g., a blood vessel) caused by excessive contact pressure applied by the electrode member 22. Furthermore, the degree of contact between the electrode clamping surface 224 and the surgical object can be determined based on the pressure changes of the electrode member 22, thereby improving surgical safety and efficiency.

[0097] In some possible embodiments of the present application, Figure 11 As shown, the second accommodating chamber 6 includes an embedded chamber 61 and a sensing chamber 62. One end of the embedded chamber 61 is connected to the wire channel 4. The sensing chamber 62 is arranged on the electrode member 22 along the clamping direction Y of the clamping assembly 2, and the sensing chamber 62 passes through the electrode clamping surface 224 to connect the clamping space 23 and the other end of the embedded chamber 61. The embedded chamber 61 matches the pressure detection member and is used to accommodate the pressure detection member. The sensing chamber 62 is used to accommodate the pressure sensing member.

[0098] In the embodiment of the present application, the second accommodating chamber 6 can be set to a structure including an embedded chamber 61 and a sensing chamber 62, so that the pressure sensor can be accommodated through the embedded chamber 61 and the pressure of the surgical object can be sensed and transmitted through the material set in the sensing chamber 62.

[0099] For example, an embedded cavity 61 can be provided at the proximal end of the electrode member 22. The embedded cavity 61 can extend along the pulling direction Z. The embedded cavity 61 is a blind hole that matches the pressure detection member. The pressure detection member can then be provided in the embedded cavity 61, and the lead 7 of the pressure detection member can be extended from the embedded cavity 61 to the lead channel 4 on the clamping member 21. A sensing cavity 62 can be provided on the electrode member 22 along the clamping direction Y, and the sensing cavity 62 can pass through the electrode clamping surface 224. In this way, the clamping space 23 and the embedded cavity 61 can be connected through the sensing cavity 62. Soft glue, soft plastic, or other materials can be provided in the sensing cavity 62. The sensing cavity 62 can be sealed by the material provided in the sensing cavity 62, and the pressure of the surgical object can be transmitted to the pressure detection member through the material provided in the sensing cavity 62.

[0100] In the above embodiment, since the second accommodating cavity 6 is configured to include an embedded cavity 61 and a sensing cavity 62, it is convenient to install a pressure detection element in the embedded cavity 61. Furthermore, the sensing cavity 62 extends through the electrode clamping surface 224 and can be filled with a soft material that easily deforms when subjected to pressure. Thus, the pressure of the surgical object can be directly transmitted to the pressure detection element via the material filled in the sensing cavity 62, which is beneficial for improving the sensitivity of the pressure detection of the surgical object and the accuracy of the obtained pressure of the surgical object.
