[0034] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0036] An embodiment of the present disclosure provides a surgical device, including a handle and a working part connected to the handle. The working part includes a cutting assembly and an electrode assembly. The cutting assembly includes a cutting member extending in the axial direction. The electrode assembly is configured to be detachably connected to the cutting assembly and includes an electrode member extending in the axial direction, wherein the electrode member is configured to be sleeved on the cutting member.

[0037] An embodiment of the present disclosure further provides a surgical system including the above surgical device.

[0038] In the surgical device and surgical system provided by the above embodiments of the present disclosure, by providing the electrode assembly, coagulation can be achieved while cutting. For example, when used in an endoscopic environment, it can achieve the effect of cutting tissue while stopping bleeding, which can not only ensure a clear surgical field of view, improve the safety of surgical operations, but also avoid repeatedly inserting coagulation instruments, improve surgical efficiency, and at the same time reduce the bleeding of patients. Further, since the electrode assembly is configured to be detachably connected to the cutting assembly, when coagulation is not required during the operation process, the electrode assembly can be removed, reducing the overall weight of the device, alleviating the burden on the operator, and increasing the flexibility in use.

[0039] The present disclosure will be described below through specific embodiments. In order to keep the description below of the embodiments of the present disclosure clear and concise, the detailed descriptions of known functions and known components may be omitted. When any component of the embodiments of the present disclosure appears in more than one drawing, the component may be denoted by the same reference numeral in each drawing.

[0040] In the embodiments of the present disclosure, "distal" and "distally" refer to the side of the surgical device away from the operator, and "proximal" and "proximally" refer to the side of the surgical device close to the operator.

[0041] Figure 1 Schematic structural diagram of the surgical device provided by the embodiments of the present disclosure. Figure 2 For Figure 1 exploded view of the surgical device. Figure 3 For Figure 2 schematic structural diagram of the cutting assembly. Figure 4 For Figure 2 schematic structural diagram of the electrode assembly.

[0042] As Figures 1 to 4 shown, the surgical device 100 provided by the embodiments of the present disclosure includes a handle 1 and a working part 2, and the working part 2 is connected to the handle 1. For example, the working part 2 is detachably connected to the handle 1, so that it is convenient to install and disassemble the working part 2, which is beneficial to disinfecting and sterilizing the working part 2, and is also beneficial to maintenance or replacement. For example, the outer shape of the handle 1 is designed to facilitate the operator to grasp the surgical device 100.

[0043] For example, the working part 2 includes a cutting assembly 10 and an electrode assembly 20. The cutting assembly 10 includes a cutting member 104 extending along the axial direction Z. The electrode assembly 20 includes an electrode member 204 extending along the axial direction Z. The electrode assembly 20 is configured to be detachably connected to the cutting assembly 10, wherein the electrode member 204 is configured to be sleeved on the cutting member 104. By setting the cutting assembly 10 and the electrode assembly 20 to be detachably connected, the needs in different scenarios can be met. For example, when only performing a cutting operation, only the cutting assembly 10 can be installed on the handle 1 without installing the electrode assembly 20. When performing a cutting operation and a coagulation operation, the cutting assembly 10 and the electrode assembly 20 can be installed.

[0044] In the embodiments of the present disclosure, the electrode assembly 20 is detachably connected to the cutting assembly 10 along the axial direction Z. At this time, the electrode member 204 is sleeved on the cutting member 104, that is, the electrode member 204 and the cutting member 104 are coaxially arranged, which is beneficial to the miniaturization and compactness of the device.

[0045] For example, the cutting assembly 10 further includes a first base 102, and the cutting member 104 is connected to the first base 102. The first base 102 is configured to be detachably connected to the handle 1. Through the above settings, it is convenient to install or disassemble the working part 2 including the cutting assembly 10 and the electrode assembly 20 on the handle 1.

[0046] For example, the first base 102 and the handle 1 are detachably connected through a docking structure. Refer to Figure 2 , this docking structure includes a docking hole P1 provided at the distal end of the handle 1 and a proximal docking portion P2 provided at the first base 102. The docking portion P2 can be inserted into the docking hole P1 to achieve a detachable connection. It can be understood that, Figure 2The illustration is for illustration only, and other embodiments of the present disclosure may also adopt other forms of docking structures, which are not limited in the embodiments of the present disclosure.

[0047] For example, the electrode assembly 20 further includes a second base 202, the electrode component 204 is connected to the second base 202, and the second base 202 is configured to be detachably connected to the first base 102. Through the above arrangement, it is convenient to install or remove the electrode assembly 20 on the cutting assembly 10. In the axial direction Z, the first base 102 is closer to the handle 1 than the second base 202, so that the second base 202 can be installed and removed more quickly.

[0048] For example, the outer surface of the handle 1, the outer surface of the first base 102 and the outer surface of the second base 202 are connected to each other and are arranged as a streamlined surface. The streamlined surface is a smooth surface, which is convenient for the operator to grasp and avoids being hooked by other surgical instruments nearby during operation.

[0049] For example, the cutting component 104 includes a first sleeve 310 and a first electrode head 312. The first sleeve 310 extends along the axial direction Z and includes a first distal portion 310A and a first proximal portion 310B. The first electrode head 312 is connected to the first distal portion 310A of the first sleeve 310 and is configured to have a spherical surface. In actual use, the first electrode head 312 will receive a first voltage (e.g., a positive high-frequency voltage) output by a plasma high-frequency generator (also referred to as a plasma host), and the second electrode head 412 will receive a second voltage (e.g., a negative high-frequency voltage) output by the plasma host. Since the first electrode head 312 is exposed, when the first electrode head 312 is exposed to a physiological saline environment, plasma energy will be stimulated, thereby coagulating the tissue. Therefore, by designing the first electrode head 312 as a spherical surface, the coagulation area can be increased.

[0050] In the embodiment of the present disclosure, the first sleeve 310 and the first electrode head 312 may be separate structures or may be an integrated structure. For example, the first sleeve 310 and the first electrode head 312 are configured as an integrated structure, which can simplify the manufacturing process and is therefore preferred.

[0051] For example, the cutting component 104 further includes a cutting piece 314, wherein the first distal end portion 310A of the first sleeve 310 is provided with a first opening portion 316 adjacent to the first electrode head 312, and the cutting piece 314 is located in the first opening portion 316. In this way, the functions of blood coagulation and tissue cutting can be achieved simultaneously. In some embodiments, the cutting piece 314 is, for example, a rotatable planer, and the cutting component 104 is provided with a suction member, which can suck the tissue to be cut into the first opening portion 316, and use the rotation of the planer to achieve cutting.

[0052] For example, the cutting assembly 10 further includes a first electrode connection portion 106 disposed on the first base 102. One end of the first electrode connection portion 106 is connected to the first power supply terminal, and the other end is connected to the first sleeve 310. The first electrode connection portion 106 is configured to be electrically connected to the first electrode head 312 through the first sleeve 310 to supply power to the first electrode head 312. Figure 5 The circuit block diagram of the surgical system provided by the embodiment of the present disclosure is shown as Figure 5 shown. The surgical system provided by the embodiment of the present disclosure includes a power host, a plasma host, and a surgical device 100. The power host supplies electrical energy to the handle 1, and the handle 1 converts the electrical energy into mechanical energy and transmits it to the cutting member 314 to perform cutting. The plasma host is electrically connected to the first electrode connection portion 106 through the first power supply terminal, and supplies a high-frequency positive voltage to the first electrode head 312 through the first electrode connection portion 106.

[0053] For example, with reference to Figure 2 and Figure 4 , the electrode component 204 includes a second sleeve 410 and a second electrode head 412. The second sleeve 410 extends along the axial direction Z and is configured to be sleeved on the first sleeve 310. The second sleeve 410 includes a second distal portion 410B and a second proximal portion 410A. The second electrode head 412 is connected to the second distal portion 410A of the second sleeve 410. The second electrode head 412 has a notch portion 414 to expose the first electrode head 312 connected to the first distal portion 310A of the first sleeve 310. By providing the notch portion 414, the exposed area of the first electrode head 312 can be further increased, and the coagulation area can be further improved. In some embodiments, the opening direction of the notch portion 414 is vertically upward, which is convenient for the operator to observe the coagulation situation from top to bottom.

[0054] In the embodiment of the present disclosure, the second sleeve 410 and the second electrode head 412 may be a split structure or an integral structure. For example, the second sleeve 410 and the second electrode head 412 are provided as an integral structure, which can simplify the manufacturing process and is therefore preferred.

[0055] For example, the notch portion 414 can also expose the first opening portion 316 located at the first distal portion 310A of the first sleeve 310 and the cutting member 314 located in the first opening portion 316. In this way, it is beneficial to expand the observation area of the operator and simultaneously observe the cutting and coagulation situations.

[0056] For example, the electrode assembly 20 further includes a second electrode connection portion 206. The second electrode connection portion 206 is disposed on the second base 202. One end of the second electrode connection portion 206 is connected to the second power supply terminal, and the other end is connected to the second sleeve 410. The first electrode connection portion 106 is configured to be electrically connected to the second electrode head 412 through the second sleeve 410 to supply power to the second electrode head 412. As Figure 5 shown, the plasma host is electrically connected to the second electrode connection portion 206 through the second power supply terminal, and supplies a high-frequency negative voltage to the second electrode head 412 through the second electrode connection portion 206. Thus, when in a physiological saline environment, a circuit is formed between the first electrode head 312 and the second electrode head 412, exciting plasma energy to achieve a blood coagulation effect.

[0057] For example, as Figure 3 shown, the cutting assembly 10 further includes an insulating layer, such as an insulating coating 108. The insulating coating 108 is disposed between the first sleeve 310 and the second sleeve 410 to insulate the first sleeve 310 and the second sleeve 410 from each other. For example, the insulating coating 108 can be formed on the entire outer surface of the first sleeve 310. It should be noted that the insulating coating 108 cannot cover the first electrode head 312 to avoid affecting the blood coagulation effect.

[0058] For example, as Figure 4 shown, the electrode assembly 20 further includes a first insulating sleeve 208. The first insulating sleeve 208 is sleeved on the second sleeve 410 to insulate the second sleeve 410 from the outside. If the first insulating sleeve 208 is not provided, the voltage on the second sleeve 410 will interfere with other nearby surgical instruments. By providing the first insulating sleeve 208, interference with other nearby surgical instruments can be avoided, achieving electrical isolation from the outside.

[0059] Above Figures 1 to 5 shows a working part 2. Optionally, the surgical device according to an embodiment of the present disclosure may further include a working part 2' with other structures. For example, Figures 6 to 9 shows another working part 2', and this working part 2' can also be installed on the handle 1 of the surgical device 100.

[0060] Figure 6 is a schematic structural diagram of a working part of a surgical device provided in another embodiment of the present disclosure. Figure 7 For Figure 6 is a schematic structural diagram of the cutting assembly. Figure 8 For Figure 6 is a schematic structural diagram of the electrode assembly. Figure 9 For Figure 8 is an exploded view of the electrode assembly.

[0061] As Figures 6 to 9As shown, the surgical device 100 provided by the embodiments of the present disclosure includes a handle 1 and a working part 2', and the working part 2' is connected to the handle 1. For example, the working part 2' is detachably connected to the handle 1, so that it is convenient to install and disassemble the working part 2', which is beneficial to disinfecting and sterilizing the working part 2', and is also beneficial to maintenance or replacement.

[0062] For example, the working part 2' includes a cutting assembly 10' and an electrode assembly 20'. The cutting assembly 10' includes a cutting member 104' extending along the axial direction Z. The electrode assembly 20' includes an electrode member 204' extending along the axial direction Z. The electrode assembly 20' is configured to be detachably connected to the cutting assembly 10', wherein the electrode member 204' is configured to be sleeved on the cutting member 104'. By setting the cutting assembly 10' and the electrode assembly 20' to be detachably connected, the needs in different scenarios can be met. For example, when only performing a cutting operation, only the cutting assembly 10' can be installed on the handle 1 without installing the electrode assembly 20'. When performing a cutting operation and a coagulation operation, the cutting assembly 10' and the electrode assembly 20' can be installed.

[0063] In the embodiments of the present disclosure, the electrode assembly 20' is detachably connected to the cutting assembly 10' along the axial direction Z. At this time, the electrode member 204' is sleeved on the cutting member 104', that is, the electrode member 204' and the cutting member 104' are coaxially arranged, which is beneficial to the miniaturization and compactness of the device.

[0064] For example, the cutting assembly 10' further includes a first base 102', and the cutting member 104' is connected to the first base 102'. The first base 102' is configured to be detachably connected to the handle 1. Through the above setting, it is convenient to install or disassemble the working part 2' including the cutting assembly 10' and the electrode assembly 20' on the handle 1. For example, the first base 102' and the handle 1 are detachably connected through a docking structure. For the specific setting method of the docking structure, reference can be made to the description of the previous embodiments, and details will not be elaborated here.

[0065] For example, the electrode assembly 20' further includes a second base 202', and the electrode member 204' is connected to the second base 202'. The second base 202' is configured to be detachably connected to the first base 102'. Through the above setting, it is convenient to install or disassemble the electrode assembly 20' on the cutting assembly 10'. In the axial direction Z, the first base 102' is closer to the handle 1 than the second base 202', so that the second base 202' can be installed and disassembled more quickly.

[0066] For example, the outer surfaces of the handle 1, the first base 102', and the second base 202' are in contact with each other and are provided as streamlined surfaces, which are smooth surfaces, facilitating the operator's grasping and avoiding being hooked by other surgical instruments nearby during the operation.

[0067] For example, the cutting component 104' includes a first cannula 310' and a cutting piece 314'. The first cannula 310' extends along the axial direction Z and includes a first distal portion 310'A and a first proximal portion 310'B. A first opening 316' is provided at the first distal portion 310'A of the first cannula 310', and the cutting piece 314' is located in the first opening 316'. By providing the cutting piece 314', the functions of coagulating and cutting tissue can be achieved simultaneously. In some embodiments, the cutting piece 314' is, for example, a rotatable shaver, and the cutting component 104' is provided with a suction member that can suck the tissue to be cut into the first opening 316' and utilize the rotation of the shaver to achieve cutting.

[0068] For example, the cutting component 104' further includes a first electrode head 312' that is connected to the first distal portion 310'A of the first cannula 310' and is configured to have a spherical surface. Different from the previous embodiments, there is no current or voltage on both the first cannula 310' and the first electrode head 312'. In the embodiments of the present disclosure, the second cannula 410' receives a first voltage (such as a high-frequency positive voltage) output by the plasma host, and the second electrode head 412' receives a second voltage (such as a high-frequency negative voltage) output by the plasma host. In this way, when in a physiological saline environment, a circuit is formed between the second cannula 410' and the second electrode head 412' to excite plasma energy and achieve a coagulation effect.

[0069] In the embodiments of the present disclosure, the first cannula 310' and the first electrode head 312' can be of a split structure or an integral structure. For example, the first cannula 310' and the first electrode head 312' are provided as an integral structure, which can simplify the manufacturing process and is therefore preferred.

[0070] For example, referring to Figure 8 and Figure 9, the electrode component 204’ includes a second sleeve 410’ and a second electrode head 412’. The second sleeve 410’ extends along the axial direction Z and is configured to be sleeved on the first sleeve 310’. The second sleeve 410’ includes a second distal portion 410’A and a second proximal portion 410’B. A second opening 416 is provided at the second distal portion 410’A of the second sleeve 410’ to expose the first opening 316’ and the cutting member 314’ located in the first opening 316’. In this way, it is beneficial to expand the operator's observation area and simultaneously observe the cutting and coagulation conditions. The opening direction of the second opening 416 is upward to facilitate the operator's top-down observation.

[0071] Figure 9 The second electrode head 412’ in [description] adopts a flat head shape. It can be understood that the second electrode head 412’ can also adopt shapes such as columnar, hook-shaped, ring-shaped or serrated. The embodiments of the present disclosure do not limit this.

[0072] For example, the electrode assembly 20’ further includes a first electrode connection portion 106’. The first electrode connection portion 106’ is provided on the second base 202’. One end of the first electrode connection portion 106’ is connected to the first power supply terminal, and the other end is connected to the second sleeve 410’. The first electrode connection portion 106’ is configured to be electrically connected to the second sleeve 410’ to supply power to the second sleeve 410’. Figure 10 is a circuit block diagram of a surgical system provided by another embodiment of the present disclosure. As Figure 10 shown, the surgical system includes a power host, a plasma host and a surgical device 100’. The power host supplies electrical energy to the handle 1. The handle 1 converts the electrical energy into mechanical energy and supplies it to the cutting member 314’ to perform cutting. The plasma host is electrically connected to the first electrode connection portion 106’ through the first power supply terminal and supplies a high-frequency positive voltage to the second sleeve 410’ through the first electrode connection portion 106’.

[0073] For example, the electrode component 204’ further includes a second electrode head 412’ and an insulating block 418. The second electrode head 412’ is provided on the second distal portion 410’A of the second sleeve 410’. The insulating block 418 is provided between the second distal portion 410’A of the second sleeve 410’ and the second electrode head 412’ to insulate the second sleeve 410’ and the second electrode head 412’. By providing the second sleeve 410’, the insulating block 418 and the second electrode head 412’ in the electrode assembly 20’, a plasma double-electrode structure can be realized on the same electrode assembly 20’, so as to realize the coagulation function through the second electrode head 412’. Compared with the previous embodiments, the overall structure of the cutting assembly is simplified.

[0074] For example, referring to Figures 8 to 10, the electrode assembly 20' further includes a second electrode connection portion 206' and a conductive portion, and the conductive portion is, for example, at least one wire 205. The second electrode connection portion 206' is disposed on the second base 202' and connected to the second power supply terminal. One end of the wire 205 is connected to the second electrode connection portion 206', and the other end is connected to the second electrode head 412'. The second electrode connection portion 206' is configured to be electrically connected to the second electrode head 412' via the wire 205 to supply power to the second electrode head 412'. The plasma host is electrically connected to the second electrode connection portion 206' through the second power supply terminal, and supplies a high-frequency positive voltage to the second electrode head 412' through the second electrode connection portion 106'. By providing the conductive portion, voltage or current transmission can be provided to the second electrode head 412' for blood coagulation.

[0075] To reduce the space occupied on the first base 202', for example, the first electrode connection portion 106' and the second electrode connection portion 206' can be disposed on the same connection base.

[0076] For example, the electrode assembly 20' further includes a wire fixing portion, and the wire fixing portion is, for example, a wire fixing plate 207. The wire fixing plate 207 extends along the axial direction Z and is connected to the outside of the second sleeve 410'. A receiving portion for receiving the wire 205 is provided between the wire fixing plate 207 and the second sleeve 410'. The receiving portion is, for example, a gap between the inner surface of the wire fixing plate 207 and the outer surface of the second sleeve 410', and the wire 205 can be disposed in the gap. Since the temperature of the wire 205 is relatively high during use, by providing the wire fixing portion, the influence of the high temperature on other surrounding surgical instruments or tissues can be avoided.

[0077] For example, the electrode assembly 20' further includes a second insulating sleeve 209. The second insulating sleeve 209 is sleeved on the second sleeve 410' and the wire fixing plate 207 to insulate the second sleeve 410', the wire fixing plate 207 and the outside from each other. If the second insulating sleeve 209 is not provided, the voltage on the second sleeve 410' will interfere with other nearby surgical instruments. By providing the second insulating sleeve 209, interference with other nearby surgical instruments can be avoided, and electrical isolation from the outside can be achieved.

[0078] In the surgical device and surgical system provided by the above embodiments of the present disclosure, by providing an electrode assembly, coagulation can be achieved while cutting. For example, when used in an endoscopic environment, it can achieve the effect of cutting tissue while stopping bleeding, which can not only ensure a clear surgical field, improve the safety of surgical operations, but also avoid repeatedly inserting coagulation instruments, improve surgical efficiency, and at the same time reduce the bleeding of patients. Further, since the electrode assembly is detachably connected to the cutting assembly, when coagulation is not required during the operation, the electrode assembly can be removed, reducing the overall weight of the device, reducing the burden on the operator, and increasing the flexibility in use.

[0079] In this article, the following points need to be noted:

[0080] (1) The drawings of the embodiments of the present disclosure only relate to the structures involved in the embodiments of the present disclosure, and other structures can refer to the general design.

[0081] (2) Without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other to obtain new embodiments.

[0082] (3) The above are only exemplary embodiments of the present disclosure and are not used to limit the protection scope of the present disclosure. The protection scope of the present disclosure is determined by the appended claims.
