[0034] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without any creative effort belong to the scope of protection of the present disclosure.

[0035] Unless otherwise defined, technical terms or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terms "first", "second", and the like, as used in the description and the claims of this disclosure do not have any specific meaning, and are used only to distinguish different components. The terms "comprise", "comprising", and the like, mean that the elements or objects listed after the terms are included in the "comprising" or "comprises" clause, and the like, and do not exclude other elements or objects. The terms "connected" or "coupled" or the like, do not mean only physical or mechanical connections or couplings, but can also include electrical connections or couplings, whether direct or indirect. The terms "upper", "lower", "left", "right", and the like, are used only to indicate relative positions, and when the absolute positions of the described objects are changed, the relative positions may also be changed accordingly.

[0036] The surgical device provided by the embodiments of the present disclosure includes 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 component extending in an axial direction. The electrode assembly is configured to be detachably connected to the cutting assembly and includes an electrode component extending in the axial direction, wherein the electrode component is configured to be sleeved on the cutting component.

[0037] The surgical device provided by the embodiments of the present disclosure includes 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 component extending in an axial direction. The electrode assembly is configured to be detachably connected to the cutting assembly and includes an electrode component extending in the axial direction, wherein the electrode component is configured to be sleeved on the cutting component.

[0038] The surgical device and the surgical system provided by the embodiments of the present disclosure can achieve coagulation while cutting by providing the electrode assembly. For example, when used in an endoscopic environment, the effect of cutting tissue while stopping bleeding can be achieved, which can ensure a clear surgical field and improve the safety of surgical operation, avoid repeated insertion of coagulation instruments, improve surgical efficiency, and reduce bleeding of patients. Further, since the electrode assembly is configured to be detachably connected to the cutting assembly, when coagulation is not needed during operation, the electrode assembly can be detached, which can reduce the overall weight of the device, reduce the burden on the operator, and increase the flexibility of use.

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

[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 A structural schematic diagram of a surgical device provided by an embodiment of the present disclosure. Figure 2 A Figure 1 An exploded view of the surgical device. Figure 3 A Figure 2 A structural schematic diagram of a cutting assembly. Figure 4 A Figure 2 A structural schematic diagram of an electrode assembly.

[0042] As shown in Figure 1 to Figure 4 , the surgical device 100 provided by an embodiment of the present disclosure comprises 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 the working part 2 is convenient to install and disassemble, which is conducive to sterilization and disinfection of the working part 2, and is also conducive to maintenance or replacement. For example, the handle 1 is designed to facilitate the operator to hold the surgical device 100.

[0043] For example, the working part 2 comprises a cutting assembly 10 and an electrode assembly 20, the cutting assembly 10 comprises a cutting component 104 extending along an axial direction Z. The electrode assembly 20 comprises an electrode component 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 component 204 is configured to be sleeved on the cutting component 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 cutting operation is performed, only the cutting assembly 10 can be installed on the handle 1, and the electrode assembly 20 is not installed. When cutting operation and coagulation operation are performed, the cutting assembly 10 and the electrode assembly 20 can be installed.

[0044] In an embodiment 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 component 204 is sleeved on the cutting component 104, that is, the electrode component 204 and the cutting component 104 are coaxially arranged, which is conducive to miniaturization and compactness of the device.

[0045] For example, the cutting assembly 10 further comprises a first base 102, the cutting component 104 is connected to the first base 102, and 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.

[0046] For example, the first base 102 and the handle 1 are detachably connected through a docking structure. Referring to Figure 2 , the docking structure comprises a docking hole P1 provided at a distal end of the handle 1 and a docking part P2 provided at a proximal end of the first base 102, and the docking part P2 can be inserted into the docking hole P1 to realize detachable connection. It can be understood that Figure 2The docking structure shown is only illustrative, and other forms of docking structure can also be adopted in other embodiments of the present disclosure, which are not limited in this regard.

[0047] For example, the electrode assembly 20 further comprises a second base 202, and 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, the electrode assembly 20 can be conveniently mounted or detached 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 more quickly mounted and detached.

[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 in contact with each other and are arranged as a streamlined surface, which is a smooth surface, facilitating the operator to hold and avoiding being hooked by other surgical instruments in the operation process.

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

[0050] In embodiments of the present disclosure, the first sleeve 310 and the first electrode head 312 can be a split structure or an integral structure. For example, the first sleeve 310 and the first electrode head 312 are arranged as an integral structure, which can simplify the manufacturing process, and therefore is preferred.

[0051] For example, the cutting component 104 further comprises a cutting member 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 member 314 is located in the first opening portion 316. In this way, the functions of coagulating and cutting the tissue can be realized at the same time. In some embodiments, the cutting member 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 the rotation of the planer can realize the cutting.

[0052] For example, the cutting assembly 10 further comprises a first electrode connecting part 106, which is arranged on the first base 102, one end of the first electrode connecting part 106 is connected to the first power supply end, and the other end is connected to the first sleeve 310; the first electrode connecting part 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 A circuit block diagram of the surgical system provided by the embodiments of the present disclosure is shown in FIG. 3. As shown in FIG. 3, the surgical system provided by the embodiments of the present disclosure comprises a power master, a plasma master and a surgical device 100. The power master supplies electric energy to the handle 1, and the handle 1 converts the electric energy into mechanical energy and transmits the mechanical energy to the cutting member 314 to perform cutting. The plasma master is electrically connected to the first electrode connecting part 106 through the first power supply end, and provides a high-frequency positive voltage to the first electrode head 312 through the first electrode connecting part 106. Figure 5

[0053] For example, referring to FIGS. 4 and 5, the electrode part 204 comprises 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 comprises a second distal end portion 410B and a second proximal end portion 410A. The second electrode head 412 is connected to the second distal end 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 end 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 condition from top to bottom. Figure 2 Figure 4 In the embodiments of the present disclosure, the second sleeve 410 and the second electrode head 412 can be a split structure or an integrated structure. For example, the second sleeve 410 and the second electrode head 412 are arranged as an integrated structure, which can simplify the manufacturing process, and therefore is preferred.

[0054] For example, the notch portion 414 can also expose the first opening portion 316 located at the first distal end 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 at the same time, the cutting and coagulation conditions can be observed.

[0055]

[0056] ​​​For example, the electrode assembly 20 further comprises a second electrode connecting part 206, which is arranged on the second base 202, one end of the second electrode connecting part 206 is connected to the second power supply end, and the other end is connected to the second sleeve 410. The first electrode connecting part 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 shown in Figure 5 , the plasma host is electrically connected to the second electrode connecting part 206 through the second power supply end, and provides a high-frequency negative voltage to the second electrode head 412 through the second electrode connecting part 206. In this way, when in a physiological saline environment, a loop is formed between the first electrode head 312 and the second electrode head 412, plasma energy is excited, and a coagulation effect is achieved.

[0057] For example, as shown in Figure 3 , the cutting assembly 10 further comprises an insulating layer, for example, an insulating coating 108, which is arranged 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 coagulation effect.

[0058] For example, as shown in Figure 4 , the electrode assembly 20 further comprises a first insulating sleeve 208, which is sleeved on the second sleeve 410 to insulate the second sleeve 410 from the outside. If the first insulating sleeve 208 is not arranged, the voltage on the second sleeve 410 can interfere with other surgical instruments nearby. By arranging the first insulating sleeve 208, interference with other surgical instruments nearby can be avoided, and electrical isolation from the outside world can be achieved.

[0059] The above Figure 1 to Figure 5 shows a working part 2. Alternatively, the surgical device of the embodiment of the present disclosure can also comprise a working part 2' of other structures. For example, Figure 6 to Figure 9 shows another working part 2', which can also be installed on the handle 1 of the surgical device 100.

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

[0061] As Figure 6 to Figure 9As shown, the surgical device 100 provided by the embodiment of the present disclosure comprises a handle 1 and a working part 2', which is connected to the handle 1. For example, the working part 2' is detachably connected to the handle 1, so that the working part 2' is convenient to install and disassemble, which is beneficial to sterilize and disinfect the working part 2' and is also beneficial to maintenance or replacement.

[0062] For example, the working part 2' comprises a cutting assembly 10' and an electrode assembly 20', the cutting assembly 10' comprises a cutting component 104' extending along an axial direction Z. The electrode assembly 20' comprises an electrode component 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 component 204' is configured to be sleeved on the cutting component 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 a cutting operation is performed, only the cutting assembly 10' can be installed on the handle 1 without installing the electrode assembly 20'. When a cutting operation and a coagulation operation are performed, the cutting assembly 10' and the electrode assembly 20' can be installed.

[0063] In the embodiment 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 component 204' is sleeved on the cutting component 104', that is, the electrode component 204' and the cutting component 104' are coaxially arranged, which is beneficial to miniaturization and compactness of the device.

[0064] For example, the cutting assembly 10' further comprises a first base 102', the cutting component 104' is connected to the first base 102', and the first base 102' is configured to be detachably connected to the handle 1. Through the above setting, the working part 2' including the cutting assembly 10' and the electrode assembly 20' is convenient to install or disassemble on the handle 1. For example, the first base 102' and the handle 1 are detachably connected through a docking structure, and the specific setting mode of the docking structure can be referred to the description of the previous embodiment, which will not be described here.

[0065] For example, the electrode assembly 20' further comprises 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 setting, the electrode assembly 20' is convenient to install or disassemble 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 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 configured as streamlined surfaces. These streamlined surfaces are smooth surfaces, which are convenient for the operator to grip and prevent them from being hooked by other surgical instruments nearby during operation.

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

[0068] For example, the cutting component 104' also includes a first electrode head 312', which is connected to the first distal portion 310'A of the first sleeve 310' and is configured to have a spherical surface. Unlike the previous embodiment, there is no current or voltage on either the first sleeve 310' or the first electrode head 312'. In this embodiment, the second sleeve 410' receives a first voltage (e.g., a high-frequency positive voltage) output by the plasma generator, and the second electrode head 412' receives a second voltage (e.g., a high-frequency negative voltage) output by the plasma generator. Thus, when in a saline environment, a circuit is formed between the second sleeve 410' and the second electrode head 412', stimulating plasma energy and achieving a coagulation effect.

[0069] In this embodiment, the first sleeve 310' and the first electrode head 312' can be either separate structures or an integral structure. For example, setting the first sleeve 310' and the first electrode head 312' as an integral structure simplifies the manufacturing process and is therefore preferred.

[0070] For example, refer to Figure 8 and Figure 9The 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 end portion 410'A and a second proximal end portion 410'B. The second distal end portion 410'A of the second sleeve 410' is provided with a second opening portion 416 to expose the first opening portion 316' and the cutting member 314' located in the first opening portion 316'. In this way, the observation area of the operator is expanded, and the cutting and coagulation conditions can be observed at the same time. The opening direction of the second opening portion 416 is upward, so as to facilitate the operator to observe from top to bottom.

[0071] Figure 9 The second electrode head 412' in the second sleeve 410' is in a flat head shape. It can be understood that the second electrode head 412' can also be in a columnar shape, a hook shape, a ring shape, or a sawtooth shape, and the embodiments of the present disclosure are not limited thereto.

[0072] For example, the electrode assembly 20' further includes a first electrode connecting portion 106' provided on the second base 202'. One end of the first electrode connecting portion 106' is connected to the first power supply end, and the other end is connected to the second sleeve 410'. The first electrode connecting portion 106' is configured to be electrically connected to the second sleeve 410' to supply power to the second sleeve 410'. Figure 10 A circuit block diagram of a surgical system is provided for another embodiment of the present disclosure. As shown in Figure 10 The surgical system includes a power master, a plasma master, and the surgical device 100'. The power master provides electric energy to the handle 1, and the handle 1 converts the electric energy into mechanical energy to be provided to the cutting member 314' to perform cutting. The plasma master is electrically connected to the first electrode connecting portion 106' through the first power supply end, and provides a high-frequency positive voltage to the second sleeve 410' through the first electrode connecting 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 end portion 410'A of the second sleeve 410', and the insulating block 418 is provided between the second distal end 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 provided on the same electrode assembly 20', so that the coagulation function is realized through the second electrode head 412'. Compared with the previous embodiments, the overall structure of the cutting assembly is simplified.

[0074] For example, with reference to Figure 8 to Figure 10The electrode assembly 20' further comprises a second electrode connecting portion 206' and a conductive portion, for example, at least one wire 205. The second electrode connecting portion 206' is arranged on the second base 202' and connected to the second power supply end. One end of the wire 205 is connected to the second electrode connecting portion 206', and the other end is connected to the second electrode head portion 412'. The second electrode connecting portion 206' is configured to be electrically connected to the second electrode head portion 412' through the wire 205 to supply power to the second electrode head portion 412'. The plasma main machine is electrically connected to the second electrode connecting portion 206' through the second power supply end, and provides a high-frequency positive voltage to the second electrode head portion 412' through the second electrode connecting portion 106'. By arranging the conductive portion, the voltage or current transmission can be provided to the second electrode head portion 412' for coagulation.

[0075] In order to reduce the space occupied on the first base 202', for example, the first electrode connecting portion 106' and the second electrode connecting portion 206' can be arranged on the same connecting seat.

[0076] For example, the electrode assembly 20' further comprises a wire fixing portion, for example, a wire fixing plate 207, which extends in the axial direction Z and is connected to the outside of the second sleeve 410'. A receiving portion for receiving the wire 205 is arranged 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 arranged in the gap. Since the wire 205 has a high temperature during use, the influence of high temperature on other surgical instruments or tissues around can be avoided by arranging the wire fixing portion.

[0077] For example, the electrode assembly 20' further comprises a second insulating sleeve 209, which is sleeved on the second sleeve 410' and the wire fixing plate 207, so as 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 arranged, the voltage on the second sleeve 410' will interfere with other surgical instruments nearby. By arranging the second insulating sleeve 209, interference with other surgical instruments nearby can be avoided, and electrical isolation from the outside can be achieved.

[0078] In the surgical device and the surgical system provided by the embodiments of the present disclosure, the electrode assembly is arranged, so that coagulation can be performed while cutting. For example, when used in an endoscopic environment, the effect of cutting tissue while stopping bleeding can be achieved, which can ensure a clear surgical field and improve the safety of surgical operation, avoid repeatedly inserting coagulation instruments, improve the efficiency of surgical operation, and reduce bleeding of patients. Further, since the electrode assembly is arranged to be detachably connected to the cutting assembly, when coagulation is not needed during operation, the electrode assembly can be detached, the overall weight of the device is reduced, the burden on the operator is reduced, and the flexibility in use is increased.
