Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an energy device terminal, a universal energy device, and a surgical instrument. Background Technology

[0002] High-frequency electrosurgical units, as a typical representative of electrosurgical instruments, not only possess excellent cutting efficiency and hemostasis, but also offer versatile surgical electrodes to meet diverse clinical needs. Their ease of operation and low cost make them suitable for various small and medium-sized hospitals. High-frequency electrosurgical units utilize the intense vibration and frictional heat generated when high-frequency current flows through human tissue, causing cell rupture and vaporization, and protein denaturation and coagulation, thus achieving cutting and hemostasis.

[0003] Traditional high-frequency electrosurgical units include an instrument box, an instrument rod, and an end effector. The instrument box is used to connect to the robot body and provide power for the movement of the end effector. The instrument rod connects the end effector and the instrument box. The end effector can perform pitching, yaw, and other movements relative to the instrument rod. Electrodes are integrated on the end effector. Electrodes come in various forms, such as hook-shaped electrodes, shovel-shaped electrodes, pen-shaped electrodes, and ring-shaped electrodes, and are suitable for different departments and surgical procedures.

[0004] However, because the actuator and electrode are integrated in traditional technology, the entire high-frequency electrosurgical unit, including the instrument box, instrument rod, and actuator, needs to be replaced when changing different electrodes. This results in higher usage costs for high-frequency electrosurgical units in traditional technology, increasing the financial burden on patients. Summary of the Invention

[0005] Based on this, the present invention provides an energy device terminal and a universal energy device and surgical instrument, which separates the energy electrode from the energy device terminal, effectively reducing surgical costs.

[0006] One aspect of this invention discloses an energy device terminal, which includes a hollow shell and a connecting assembly, wherein the hollow shell is connected to the connecting assembly; the connecting assembly includes a first connecting end and a second connecting end, the first connecting end being used for electrical connection to an external power source, and the second connecting end including a mechanical connecting part and a conductive part, the conductive part being electrically connected to the first connecting end; when an energy electrode is connected to the mechanical connecting part, the energy electrode is electrically connected to the conductive part.

[0007] In some embodiments, the mechanical connection includes a slot or insertion portion, the slot or insertion portion having a threaded structure that mates with the energy electrode.

[0008] In some embodiments, the mechanical connection portion includes a slot portion and / or an insertion portion, wherein the slot portion and the insertion portion have protrusions and / or grooves on their walls along the insertion direction that mate with the energy electrode.

[0009] In some embodiments, the wall surfaces of the slot portion and the insertion portion are provided with guide structures that guide the energy electrodes to move along the insertion direction.

[0010] In some embodiments, the mechanical connection includes at least two combined connection holes arranged in a ring. The combined connection holes include a first insertion hole, a second insertion hole, and a through-shaft groove connecting the first insertion hole and the second insertion hole. The through-shaft groove is provided with a limiting member that restricts the energy electrode from circumferentially disengaging from the first insertion hole. The energy electrode can be axially inserted into the second insertion hole and then circumferentially passed through the through-shaft groove into the first insertion hole, so that the energy electrode is constrained axially and circumferentially within the first insertion hole.

[0011] In some embodiments, the limiting member is a spring-loaded structure.

[0012] In some embodiments, the conductive part and the mechanical connection part are integrally disposed, or the conductive part and the mechanical connection part are disposed independently.

[0013] In some embodiments, the hollow shell has a through hole, and both the first connecting end and the second connecting end are disposed within the hollow shell. The energy electrode can pass through the through hole and connect to the mechanical connection portion of the second connecting end; alternatively, the first connecting end is disposed within the hollow shell, while the second connecting end extends outward through the through hole. In some embodiments, the end of the energy device further includes a sealing assembly. When the second connecting end is disposed inside the hollow shell, the sealing assembly seals the gap between the energy electrode and the through hole; when the second connecting end extends outward from the hollow shell through the through hole, the sealing assembly seals the gap between the connecting assembly and the through hole.

[0014] In some embodiments, the sealing component is an elastic sealing gasket.

[0015] A second aspect of the present invention discloses a universal energy device, comprising an device box, an device rod, and any of the aforementioned energy device ends, wherein one end of the device rod is connected to the device box, the other end of the device rod is connected to the hollow shell of the energy device end, and the first connection end of the connection assembly between the device box and the energy device end is electrically connected.

[0016] In some embodiments, the general-purpose energy device further includes a thermal insulation component for mounting on the energy electrode.

[0017] In some embodiments, the outer diameter of the insulating component tapers at one end of the hollow housing away from the end of the energy device.

[0018] In some embodiments, when the energy device end includes the sealing assembly, the sealing assembly is located between the hollow housing and the insulation assembly, the insulation assembly has a receiving groove for accommodating the sealing assembly on the side facing the hollow housing, and / or the hollow housing has a sink groove for accommodating the sealing assembly on the side facing the insulation assembly.

[0019] A third aspect of the present invention discloses a surgical instrument, including an energy electrode and any of the aforementioned general energy devices.

[0020] In some embodiments, the mechanical connection portion at the end of the universal energy device includes at least two combined connection holes arranged in annularly. The combined connection holes include a first insertion hole, a second insertion hole, and a through-shaft groove connecting the first insertion hole and the second insertion hole. The through-shaft groove is provided with a limiting member that restricts the energy electrode from circumferentially disengaging from the first insertion hole.

[0021] The energy electrode includes a working end and a connecting shaft. The connecting shaft includes a thicker section away from the working end and a thinner section close to the working end. The second insertion hole at the end of the energy device can accommodate the thicker section and the thinner section. The first insertion hole has a cavity that can accommodate the thicker section and an opening with a diameter smaller than that of the thicker section but larger than that of the thinner section.

[0022] The energy electrode can be axially inserted into the second socket and then circumferentially passed through the through-shaft groove into the first socket. The thicker section of the energy electrode is axially limited by the opening of the first socket, and the energy electrode is circumferentially limited within the first socket by the limiting member.

[0023] Beneficial effects

[0024] Compared to traditional technologies where the energy electrode and actuator are integrated, leading to higher replacement costs, the energy instrument end and energy electrode described in this invention are independent. This allows the energy electrode to still be manufactured in traditional shapes such as hooks, shovels, pens, and rings to achieve its existing functions, but it can be produced and managed as an independent component. When a different energy electrode needs to be replaced, the surgical instrument using the energy instrument end of this invention no longer requires replacing the entire high-frequency electrosurgical unit. Instead, the energy electrode is removed from the energy instrument end and connected to the mechanical connection part of the energy instrument end. At this time, the conductive part of the energy instrument end is also electrically connected to the energy electrode. In this way, the replacement of the energy electrode is completed, reducing the usage cost of this surgical instrument. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0047] See Figure 1 , Figure 1 An exploded view of the end effector of an energy device according to an embodiment of the present invention is shown. The end effector includes a hollow housing 200 and a connecting assembly 100. The hollow housing 200 is used to connect to the instrument rod of a general-purpose energy device, and the hollow housing 200 can move relative to the instrument rod. The connecting assembly 100 is mounted on the hollow housing 200 and is used to connect to an external energy electrode 500. With this configuration, the movement of the hollow housing 200 relative to the instrument rod will cause the connecting assembly 100 and the energy electrode 500 to move relative to the instrument rod, thereby enabling various actions during surgery. Specifically, as shown... Figure 1As shown, the connection assembly 100 includes a first connection end 101 and a second connection end 102. The first connection end 101 is used for electrical connection to an external power source, such as the instrument box in a general energy device. The second connection end 102 includes a mechanical connection part and a conductive part. The conductive part is electrically connected to the first connection end 101. When the energy electrode 500 is connected to the mechanical connection part of the second connection end, the energy electrode 500 is simultaneously electrically connected to the conductive part.

[0048] The energy device tip of the present invention has a mechanical connection portion and a conductive portion on its second connection end of the connection assembly 100. The energy electrode 500 can be stably connected to the connection assembly 100 through the mechanical connection portion, which fixes the relative position of the energy device tip and the energy electrode 500, allowing for precise control of the position of the energy electrode 500 during surgery. Furthermore, when the energy electrode 500 is connected to the mechanical connection portion, it forms a reliable electrical connection with the conductive portion. An external power source supplies power to the energy electrode 500 sequentially through the conductive portions of the first connection end and the second connection end, thus ensuring the surgical stability of the medical device using the energy device tip of the present invention.

[0049] Compared to traditional technologies where the energy electrode 500 and the actuator end are integrated, resulting in higher replacement costs, the energy instrument end and the energy electrode 500 described in this invention are independent of each other. This allows the energy electrode 500 to still be manufactured in the traditional hook, shovel, pen, or ring shapes to achieve its existing functions, but it can be produced and managed as an independent component. When it is necessary to replace a different energy electrode 500, surgical instruments using the energy instrument end of this invention do not require replacement of the energy instrument end itself; instead, the energy electrode 500 is simply removed from the end and replaced with the required one, thus reducing the usage cost of this surgical instrument.

[0050] It is understood that the mechanical connection portion at the end of the energy device of the present invention can be implemented in various forms. For example, the mechanical connection portion can be provided with a threaded structure that mates with the energy electrode 500. Specifically, in cases such as Figure 1 In the embodiment shown, the second connecting end 102 is provided with a slot portion 103, and the energy electrode 500 is provided with an insertion portion 520 corresponding to the slot portion 103. The slot portion 103 is provided with an internal thread, and the insertion portion 520 of the energy electrode 500 is provided with an external thread. In this way, the insertion portion 520 of the energy electrode 500 can be engaged with the internal thread in the slot portion 103 on the second connecting end 102 through the external thread, so that the energy electrode 500 is threadedly connected to the second connecting end 102.

[0051] It is easy to understand that in other embodiments, the mechanical connection portion of the second connection end 102 may also be provided with an insertion portion having external threads, while the energy electrode 500 is provided with a slot portion having internal threads. Similar to the aforementioned scheme, the energy electrode 500 can also be threadedly connected to the second connection end 102.

[0052] It should be noted that the mechanical connection part and the conductive part can be integrally formed. Taking the aforementioned embodiment as an example, the threaded structure itself has a conductive function. For example, if the threaded structure is a metal thread, then when the energy electrode 500 forms a threaded connection with the second connection end 102, the energy electrode 500 has already formed an electrical connection with the external power source. In other embodiments, the mechanical connection part and the conductive part can also be independently formed. Again, taking the aforementioned embodiment as an example, the threaded structure itself does not participate in conductivity. As a partially feasible example, the conductive part can be a contact provided at the bottom of the slot portion, and the end of the insertion portion of the energy electrode 500 is provided with an annular conductive ring. When the energy electrode 500 forms a threaded connection with the second connection end 102, the contact comes into contact with the conductive ring on the energy electrode 500 to form an electrical connection.

[0053] In addition to threaded connections, in some embodiments, the mechanical connection may be provided with a snap-fit ​​structure that mates with the energy electrode 500. For example... Figure 2 , Figure 3 , Figure 4 In some embodiments shown, the second connecting end 102 is provided with a slot portion 103, and the energy electrode 500 is provided with an insertion portion 520 corresponding to the slot portion 103. The slot portion 103 is provided with a slot 104, and the insertion portion 520 is provided with protruding teeth 521. The insertion portion 520 of the energy electrode 500 can be inserted into the slot portion 103, so that the protruding teeth 521 on the insertion portion 520 are engaged in the slot 104 in the slot portion 103, thereby realizing the engagement and fixation of the energy electrode 500 and the second connecting end 102.

[0054] It is readily understood that in other embodiments, the second connecting end 102 may also be provided with an insertion portion, while the energy electrode 500 may be provided with a slot portion. Similar to the aforementioned scheme, the energy electrode 500 can engage with the second connecting end 102. Furthermore, in some embodiments, the insertion portion may also be provided with a slot, and the slot portion may also be provided with protruding teeth. These embodiments can also achieve engagement between the energy electrode 500 and the second connecting end 102. In other embodiments, the second connecting end 102 may simultaneously be provided with an insertion portion and a slot portion, and the corresponding energy electrode 500 may simultaneously be provided with a slot portion and an insertion portion that match the second connecting end 102, such that the insertion portion of the second connecting end 102 connects to the slot portion of the energy electrode 500, and the slot portion of the second connecting end 102 connects to the insertion portion of the energy electrode 500.

[0055] As a specific example, the protruding teeth are made of toothed metal springs. During the insertion of the insert into the slot, the metal spring is compressed to allow the insert to penetrate deeper into the slot. When the toothed metal spring moves to the groove, it returns to its toothed shape to engage with the groove. It is understood that the shape of the protruding teeth includes, but is not limited to, triangular teeth, arcuate teeth, etc.

[0056] It should be noted that although both the second connecting end 102 and the energy electrode 500 in the aforementioned embodiments with snap-fit ​​connections are provided with only one slot or insertion part, this does not mean that the number of slots or insertion parts must be limited to one, or that the second connecting end 102 and the energy electrode 500 can only be provided with slots and insertion parts respectively. In some embodiments, the second connecting end 102 can be provided with more than one insertion part and more than one slot part, and the energy electrode 500 is provided with a matching number of insertion parts and slot parts corresponding to the second connecting end 102. In these embodiments, the energy electrode 500 can still form a snap-fit ​​connection with the second connecting end 102.

[0057] In some embodiments, such as Figure 2 As shown, the wall of the slot portion 103 is provided with a guide structure 105 to guide the energy electrode 500 to move along the insertion direction. By providing the guide structure 105, the energy electrode 500 can be inserted more smoothly into the second connecting end 102, so that the protruding teeth of the energy electrode 500 and the second connecting end 102 engage with the slot to form a snap-fit. As an example, the guide structure 105 can be a guide groove extending along the insertion direction, and the corresponding energy electrode 500 is provided with a protruding slider 522, which is located in the guide groove and can slide along the guide groove. The cross-section of the guide groove perpendicular to the axial direction can be, for example, semi-circular or trapezoidal.

[0058] In addition to the aforementioned card-based connection methods, such as Figure 5 The diagram shown is of the connecting component 100. Figure 6 for Figure 5 In a cross-sectional view of section DD, in some embodiments, the mechanical connection portion of the second connection end 102 includes at least two annularly arranged combined connection holes. The combined connection holes include a first insertion hole 110, a second insertion hole 120, and a through-shaft groove 130 connecting the first insertion hole 110 and the second insertion hole 120. A limiting member 131 is provided within the through-shaft groove 130 to restrict the energy electrode 500 from circumferentially disengaging from the first insertion hole 110. In this partial embodiment, the energy electrode 500 can mate with the combined connection holes, allowing it to be axially inserted into the second insertion hole 120 and then enter the first insertion hole 110 through the through-shaft groove 130. Subsequently, the energy electrode 500 is axially and circumferentially constrained within the first insertion hole 110, achieving a mechanical connection between the energy electrode 500 and the end of the energy device.

[0059] To be more specific, such as Figure 10 The diagram shown is a schematic of the energy electrode 500 in this embodiment. The energy electrode 500 includes a working end and a connecting shaft 510. The connecting shaft 510 includes a thicker segment 512 away from the working end and a thinner segment 511 closer to the working end. Figure 7 , Figure 9 As shown, the first insertion hole 110 has a cavity 112 capable of accommodating the thicker segment 512 and an opening 111 with a diameter smaller than the thicker segment 512 but larger than the thinner segment 511, as shown. Figure 8 As shown, the second socket 120 can accommodate the connecting shaft 510. After the connecting shaft 510 of the energy electrode 500 is inserted into the second socket 120, it passes circumferentially through the shaft groove 130 and engages in the first socket 110; as shown... Figure 8 As shown, the limiting member 131 can prevent the connecting shaft 510 of the energy electrode 500 from dislodging from the first insertion hole 110 toward the shaft groove 130.

[0060] In this embodiment, because the diameter of the opening 111 of the first insertion hole 110 is smaller than that of the thicker section 512 but larger than that of the thinner section 511, when the connecting shaft 510 is inserted into the second insertion hole 120 and passes circumferentially through the shaft groove 130, when the connecting shaft 510 attempts to axially withdraw from the first insertion hole 110, the thicker section 512 of the connecting shaft 510 will be limited by the opening 111, preventing the connecting shaft 510 from being axially pulled out of the first insertion hole 110 along its insertion direction. Furthermore, because a limiting member 131 is provided in the shaft groove 130 to prevent the connecting shaft 510 from moving from the first insertion hole 110 into the shaft groove 130, the connecting shaft 510 cannot withdraw circumferentially from the first insertion hole 110 after entering it. Thus, through the cooperation between the connecting shaft 510 and the first insertion hole 110, the energy electrode 500 will be firmly engaged with the second connecting end 102.

[0061] Compared to other snap-fit ​​methods, the connection component 100 at the end of the energy device in this embodiment snaps more securely to the energy electrode 500, and the assembly steps and speed are relatively simple and fast.

[0062] It is understood that the specific form of the limiting member 131 is not strictly limited by the end of the energy device of the present invention. In some embodiments, the limiting member 131 can be a metal spring structure, which cooperates with the shaft groove 130 such that the gap width between the metal spring and the shaft groove 130 is smaller than the thinner segment of the connecting shaft 510. When the connecting shaft 510 of the energy electrode 500 moves circumferentially, the connecting shaft 510 compresses the metal spring to pass through the shaft groove 130 and enter the first insertion hole 110. When the connecting shaft 510 wants to withdraw circumferentially from the first insertion hole 110, the metal spring blocks the thinner segment 511 in the connecting shaft 510. In other embodiments, the limiting member 131 can also be a spring pin, a pin shaft, a retaining ring, etc., the principle of which is similar to that of the metal spring solution, and will not be described in detail here.

[0063] In the above-described snap-fit ​​connection embodiments, similar to the threaded connection embodiments, the mechanical connection part and the conductive part can be integrally formed or separately formed. In some embodiments, the mechanical connection part is entirely made of conductive material, in which case the mechanical connection part is also the conductive part, i.e., the mechanical connection part and the conductive part are integrally formed. When the mechanical connection part and the conductive part are separately formed, contacts can be set up in a manner similar to the threaded connection scheme, or other schemes can be used. Those skilled in the art can make specific designs according to actual needs based on the technical teachings provided by this invention.

[0064] It is readily understood that the energy device terminal of the present invention does not limit how the connecting component 100 is specifically connected to the hollow housing 200. In some embodiments, the first connecting end 101 of the connecting component 100 is disposed inside the hollow housing 200, while the second connecting end 102 is disposed outside the hollow housing 200. In this case, the hollow housing 200 is provided with a through hole 201, through which the connecting component 100 extends the second connecting end 102, thus forming a gap between the connecting component 100 and the through hole 201. Regarding this gap, as... Figure 1 , 12 As shown, the energy device end of the present invention also includes a sealing component 300, which is used to seal the gap between the connecting component 100 and the through hole 201.

[0065] In another embodiment, both the first connecting end 101 and the second connecting end 102 of the connecting assembly 100 are disposed within the hollow housing 200. In this case, the hollow housing 200 has a through hole 201, through which the energy electrode 500 passes and connects to the second connecting end 102, forming a gap between the energy electrode 500 and the through hole 201. To address this gap, as follows... Figure 1 , 12 As shown, the end of the energy device of the present invention also includes a sealing component 300, which is used to seal the gap between the energy electrode 500 and the through hole 201.

[0066] When performing surgery, the surgical instrument using the energy device end of the present invention can prevent bodily fluids from entering the hollow shell 200 through the through hole 201 by setting the sealing component 300, thus preventing the connection of the first connection end 101 of the connection component 100 from becoming unstable.

[0067] As a specific example, in some embodiments, the sealing assembly 300 can be an elastic sealing gasket. When the second connecting end 102 is inside the hollow housing 200, the elastic sealing gasket is fitted onto and sealed to the energy electrode 500, and the gasket portion of the elastic sealing gasket seals the gap between the energy electrode 500 and the through hole 201. When the second connecting end 102 is outside the hollow housing, the elastic sealing gasket is fitted onto and sealed to the connecting assembly 100, and the gasket portion of the elastic sealing gasket seals the gap between the connecting assembly 100 and the through hole 201. The material of the elastic sealing gasket can be one or more composites of elastic silicone and flexible resin.

[0068] Another aspect of the present invention discloses a universal energy device, such as Figure 15 As shown, the device includes an instrument box 3, an instrument rod 2, and any of the aforementioned energy device ends 1. One end of the instrument rod 2 is connected to the instrument box 3, and the other end of the instrument rod 2 is connected to the hollow shell 200 of the energy device end 1. The first connection end 101 of the connection assembly 100 between the instrument box 3 and the energy device end 1 is electrically connected. This universal energy device can be connected to a robot via the instrument box. Furthermore, because this universal energy device is separately and independently configured from the energy electrodes, the energy electrodes can be manufactured and managed as independent components. Doctors can flexibly replace different energy electrodes according to the surgical situation, thereby helping to improve surgical outcomes.

[0069] like Figure 1 , Figure 12 As shown, in some embodiments, the energy device end of the universal energy device of the present invention further includes a heat insulation component 400, which is used to be sleeved on the energy electrode 500. The material of the heat insulation component 400 is not limited to one or more of the following: high-insulation plastics, ceramics, insulating coatings, insulating silicone, insulating varnish, etc. The heat insulation component 400 and the energy electrode 500 can be connected by various methods such as bonding, sintering, and snap-fitting. The heat insulation component 400 can prevent the hollow shell 200 from being burned due to excessively high temperature at the working end of the energy electrode 500 during operation, and can also prevent the high temperature of the energy electrode 500 from causing accidental injury to non-surgical sites.

[0070] In some embodiments, the outer diameter of the end of the heat insulation component 400 furthest from the hollow housing 200 tapers. By setting the outer diameter of the end of the heat insulation component 400 furthest from the hollow housing 200 to taper, the influence of the heat insulation component 400 on the doctor's line of sight when observing the working end of the energy electrode 500 can be reduced. Specifically, in some embodiments, such as Figure 14 As shown, the end of the insulation component 400 away from the hollow shell 200 is provided with a chamfer 401.

[0071] In some embodiments, the universal energy device of the present invention includes a heat insulation component 400 and a sealing component 300 at the end of the energy device. Taking the sealing component 300 as an elastic sealing gasket as an example, when the energy electrode 500 is connected to the second connection end 102, the heat insulation component 400 and the elastic sealing gasket are pressed together, so that the elastic sealing gasket is pressed together with the hollow shell 200.

[0072] It is readily apparent that the universal energy device of the present invention does not limit how the sealing assembly 300 cooperates with the insulation assembly 400 and the hollow housing 200. In some embodiments, such as Figure 11 , Figure 13 As shown, the hollow shell 200 has a recess 202 surrounding the through hole 201. The sealing assembly 300 is located between the hollow shell 200 and the heat insulation assembly 400. When the energy electrode 500 is connected to the mechanical connection portion of the second connection end 102, the heat insulation assembly 400 confines the sealing assembly 300 within the recess 202. Similarly, as... Figure 14 As shown, in some embodiments, the thermal insulation component 400 has a receiving groove 402 on the side facing the sealing component 300. When the energy electrode 500 is connected to the second connection end 102, the thermal insulation component 400 cooperates with the hollow housing 200 to confine the sealing component 300 in the receiving groove 402. This arrangement prevents the sealing component 300 from being exposed to the external environment, thus helping to extend the service life of the sealing component 300.

[0073] A third aspect of this invention discloses a surgical instrument comprising an energy electrode and any of the aforementioned universal energy devices. This surgical instrument manages the energy electrode as an independent component, eliminating the need to replace the end of the energy device when replacing the energy electrode, thereby reducing economic costs during surgery.

[0074] As a preferred embodiment, the mechanical connection portion at the end of the universal energy device used in the surgical instrument of the present invention includes at least two combined connection holes arranged in annularly. The combined connection holes include a first insertion hole 110, a second insertion hole 120, and a through-shaft groove 130 connecting the first insertion hole 110 and the second insertion hole 120. A limiting member 131 is provided in the through-shaft groove 130 to restrict the energy electrode 600 from circumferentially disengaging from the first insertion hole 110.

[0075] The energy electrode 500 includes a working end and a connecting shaft 510. The connecting shaft 510 includes a thicker section 512 away from the working end and a thinner section 511 close to the working end. The second insertion hole 120 at the end of the energy device can accommodate the thicker section 512 and the thinner section 511. The first insertion hole 110 has a cavity 112 that can accommodate the thicker section 512 and an opening 111 with a diameter smaller than the thicker section 512 but larger than the thinner section 511.

[0076] After being axially inserted into the second socket 120, the energy electrode 500 passes through the shaft groove 130 and enters the first socket 110. The thicker section 512 of the energy electrode 500 is axially limited by the opening 111 of the first socket 110, and the energy electrode 500 is circumferentially limited within the first socket 110 by the limiting member 131.

[0077] In this embodiment of the surgical instrument, the second connecting end of the energy device is provided with a uniquely structured combined connecting hole. This ensures that regardless of whether the energy electrode 500 is subjected to axial or radial forces, the combined connecting hole guarantees a stable mechanical connection between the energy electrode 500 and the end of the general-purpose energy device. In addition to ensuring a stable mechanical connection, the electrical connection between the energy electrode 500 and the end of the energy device is also more stable, thereby guaranteeing the high reliability and stability of the surgical instrument of this invention.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
