Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a flushing and suction device and a bipolar electrocoagulation device. Background Art

[0002] In the medical industry, the common treatment for soft tissue abscesses is surgical incision and drainage, followed by cleaning and suturing. However, this treatment method is slow to recover and leaves large scars after healing, which affects appearance. With the continuous development of minimally invasive surgery, especially for surgeries in critical body parts, such as breast abscesses, doctors use irrigation, flushing, and aspiration to treat pus / tissue fluid, and then use electrocautery and coagulation to treat bleeding points. This requires the use of irrigators, aspirators, and high-frequency electrosurgical consumables.

[0003] Currently, the commonly used irrigation and suction equipment uses the same pipe for the irrigation and suction processes. During the suction process, some exudate will adhere to the inner wall of the pipe. During the irrigation, the exudate remaining on the pipe wall after suction is easily flushed back into the surgical space, increasing the chance of surgical infection. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the flushing process and the suction process of the currently commonly used flushing and suction equipment use the same pipeline, which increases the probability of surgical infection, thereby providing a flushing and suction equipment and a bipolar electrocoagulation equipment.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] An irrigation and suction device, comprising:

[0007] The handle has a hollow structure inside and comprises a handle proximal end and a handle distal end;

[0008] The suction branch comprises a suction tube disposed at the distal end of the handle, a suction transition tube disposed inside the handle, and a suction connecting tube disposed at the proximal end of the handle; a suction channel is formed inside the suction tube; the suction transition tube is coaxially connected to the suction tube and the suction connecting tube, and the suction transition tube is capable of telescopic adjustment;

[0009] The flushing branch comprises a flushing tube disposed at the distal end of the handle, a flushing transition tube disposed inside the handle, and a flushing connection tube disposed at the proximal end of the handle; the flushing tube is sheathed around the periphery of the suction tube, with a gap between the outer wall of the suction tube and the inner wall of the flushing tube forming a flushing channel, the flushing channel and the suction channel being disconnected; the flushing transition tube and the suction transition tube are independently disposed.

[0010] The push control assembly is arranged on the handle and connected to the suction transition tube; the push control assembly is suitable for pushing the suction transition tube and the suction tube to move toward the distal end when performing the suction action, so that the suction channel protrudes from the flushing channel.

[0011] To further optimize the technical solution, the suction transition tube includes a telescopic tube, a middle connecting tube and a suction connecting tube which are sequentially connected from the distal end to the proximal end. The telescopic tube is connected to the suction tube, and the suction connecting tube is connected to the suction connecting tube.

[0012] To further optimize the technical solution, the push control component includes a push button, which is connected to the middle connecting tube through a connecting groove; and a slide suitable for moving the push button is provided on the handle.

[0013] To further optimize the technical solution, a frame is provided inside the handle, and a telescopic tube holding cavity suitable for holding the telescopic tube is enclosed between the frame and the handle, and the telescopic tube holding cavity is sealed; a pair of through holes are opened on the frame, and the two ends of the telescopic tube are respectively fitted in the through holes by sliding and sealing with silicone rings.

[0014] To further optimize the technical solution, an opening is provided on the side wall of the telescopic tube, and a pressure regulating hole is provided on the handle, which is respectively connected to the telescopic tube containing chamber and the atmosphere, and the pressure regulating hole is suitable for adjusting the air pressure on the suction branch.

[0015] To further optimize the technical solution, the flushing transition pipe is a flushing hose; and the handle is provided with a water control component suitable for controlling the opening and closing of the flushing hose.

[0016] Further optimizing the technical solution, the water control component includes:

[0017] The lower cover spring seat is provided separately from the handle or formed by the handle structure itself;

[0018] A flush button is slidably engaged with a flush button receiving compartment provided on the handle; the flush button has a through hole suitable for allowing a flush hose to pass through;

[0019] The spring structure is arranged between the spring seat of the lower cover and the flushing button.

[0020] To further optimize the technical solution, the suction tube and the flushing tube are both elastic tubes.

[0021] To further optimize the technical solution, the proximal end of the flushing tube is sealed and fixed in the handle via a flushing tube rubber-coated part, and the flushing tube rubber-coated part has a channel equipped for flushing the transition tube.

[0022] To further optimize the technical solution, the distal end of the suction tube and / or flushing tube is provided with an arc structure to prevent scratching of tissue.

[0023] A bipolar electrocoagulation device comprising:

[0024] The irrigation and suction equipment, wherein the suction tube, the suction transition tube and the irrigation tube are conductive tubes;

[0025] A first contact spring is provided inside the handle, one end of which is in conductive contact with the flushing tube and the other end of which is connected to the power supply;

[0026] Insulation coating, covering the suction transition pipe;

[0027] A second contact spring is arranged inside the handle and located at the distal end of the insulating coating, and the second contact spring is connected to the power supply; when the control component is pushed to push the suction tube and the suction transition tube to move toward the distal end, the insulating coating contacts the second contact spring, and the flushing and suction device is in a flushing and suction state; when the control component is pushed to push the suction tube and the suction transition tube to move toward the proximal end, the suction transition tube contacts the second contact spring, and the flushing and suction device is in an electrocoagulation state.

[0028] To further optimize the technical solution, the outer periphery of the suction tube is covered with a suction tube insulating tube; the outer periphery of the flushing tube is covered with a flushing tube insulating tube.

[0029] The technical solution of the present invention has the following advantages:

[0030] 1. The present invention provides an irrigation and suction device with independent irrigation and suction channels, effectively preventing cross-contamination between the two channels. The suction and irrigation branches are fluidically isolated from each other. The irrigation tube is sheathed within the suction tube and separated by a radial gap. This radial gap forms part of the irrigation branch, freeing the internal space of the suction tube from the irrigation tube. This ensures smoother suction operation and reduces the risk of blockage.

[0031] When suctioning waste from a surgical area, the control assembly can be directly used to push the suction transition tube and the suction tube distally, dislocating the flushing tube and the suction tube. This causes the suction channel to protrude beyond the flushing channel. During the suction operation, the tissue and blood clots to be suctioned do not come into contact with the flushing tube, preventing them from entering the flushing tube and being flushed back into the body through the flushing channel, potentially causing secondary contamination. The flushing and suction branches are completely fluidically independent, preventing the possibility of suctioned fluid being flushed back into the surgical wound, increasing the risk of secondary infection.

[0032] 2. The present invention provides an irrigation and suction device in which the irrigation tube is made of a flexible metal tube, and the suction tube is made of spring steel. Furthermore, the irrigation and suction tubes are flexible, facilitating smooth access and completion of minimally invasive surgeries through various access points, meeting a wide range of intraoperative needs. Both the suction and irrigation tubes are wrapped in heat-shrink tubing.

[0033] 3. The present invention provides an irrigation and suction device with a pressure regulating hole in the shape of a water droplet, which can achieve stepless adjustment of the suction pressure. When adjusting the pressure inside the suction tube, the operator can manually press the pressure regulating hole and control the opening size of the pressure regulating hole by moving the finger, thereby controlling the negative pressure attraction force of the suction tube. The suction force of the suction tube 2 can be manually adjusted for different application scenarios. During all operations, the operator can adjust the suction force within the suction channel by blocking the pressure regulating hole, which is very convenient to control.

[0034] 4. The flushing and suction device provided by the present invention has a water control component on the handle that is suitable for controlling the opening and closing of the flushing hose. The handle is provided with a flushing button that can effectively adjust the opening and closing and flow rate of the flushing channel and is quick to operate.

[0035] 5. The flushing and suction device provided by the present invention has a smaller diameter or volume of the part entering the human body, so that more instruments can be accommodated in the surgical wound channel during surgery.

[0036] 6. The flushing and suction device provided by the present invention has all pipelines sealed and sterilely connected, reducing the chance of infection. The streamlined handle design fully meets the requirements of ergonomics.

[0037] 7. The present invention provides a flushing and suction device, in which the distal end of the suction tube is provided with an arc structure, and the contact between the distal end of the suction tube and the tissue is smoother. The outer peripheral sharp edges of the front end surface are all rounded and blunted to prevent tissue cutting, which can prevent the front end of the suction tube from scratching the tissue.

[0038] 8. The present invention provides a bipolar electrocoagulation device, which can control whether the entire device is connected to the power supply by pushing the control component, and then switch the use status of the device. It can be used as a flushing and suction device, and can also be used as a bipolar electrocoagulation consumable. It integrates suction, flushing, and electrocoagulation into one, which greatly reduces the surgical procedures, saves surgical time, and reduces surgical risks.

[0039] When the control assembly is pushed to move the suction tube and the suction transition tube toward the distal end, the insulating coating contacts the second contact spring, and the push button is pushed out so that the contact spring away from the electrode rod end is in the insulating layer, and the path is disconnected. At this time, the device as a whole is not connected to the power supply. At this time, the flushing channel and the suction channel are misaligned. The suction channel protrudes from the flushing channel, and the device is in the flushing and suction state. When the control assembly is pushed to move the suction tube and the suction transition tube toward the distal end, the flushing channel is flush with the suction channel, and the suction transition tube contacts the second contact spring, and at this time, the contact spring away from the electrode rod end is connected to the suction channel. At this time, the device as a whole is in the electrocoagulation state. More specifically, the contact spring away from the electrode rod end is connected to the suction channel, and the contact spring close to the electrode rod end is connected to the flushing channel; the circuit forms a bipolar loop through the wire → suction channel → human body → flushing channel → wire, thereby achieving coagulation.

[0040] 9. The present invention provides a bipolar electrocoagulation device with an anti-accidental touch mechanism. When the push button is pushed out, the irrigation and suction channels form a stepped position, making the electrode rod shape suitable for irrigation and suction. This disconnects the circuit, preventing accidental stepping on the electrosurgical unit's foot pedal during surgery from creating a circuit path and potentially injuring tissue. When the push button is pushed in, the irrigation and suction channels align, making the electrode rod shape suitable for electrocoagulation. The insulating section then moves backward, allowing the circuit to complete a loop.

[0041] 10. The present invention provides a bipolar electrocoagulation device that integrates flushing, suction, and electrocoagulation functions. All functions can be performed with one hand, reducing the use of instruments and simplifying the surgical process.

[0042] 11. The bipolar electrocoagulation device provided by the present invention is a disposable product, which eliminates intraoperative infection caused by repeated sterilization. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0059] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the term "distal end" generally refers to the end of a medical implant away from the operator; "proximal end," in contrast to "distal end," refers to the end of a medical implant closer to the operator.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0061] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0062] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0063] Example 1

[0064] like Figures 1 to 9 As shown, this embodiment discloses an irrigation and suction device, which is a surgical irrigation, suction, and drainage assembly, having a distal end that is farther away from the operator during use and a proximal end that is closer to the operator during use. The irrigation and suction device includes a handle, a suction branch, an irrigation branch, and a push control assembly.

[0065] The interior of the handle 1 is a hollow structure with a proximal end and a distal end. The handle is split into upper and lower parts, namely, an upper shell and a lower shell that are interlocked to form the handle. However, the handle is not limited to split parts; it can also be configured as a single-piece handle, with the shell being integral. It should be noted that the specific shape of the handle is not limited herein.

[0066] The handle can be held by the operator during surgery, so one side of the handle in this embodiment is set to a concave arc shape, which is more convenient for the operator to hold it manually.

[0067] The suction branch, used to aspirate waste from the surgical area during surgery, comprises a suction tube 2 at the distal end of the handle, a suction transition tube 4 within the handle, and a suction connection tube 11 at the proximal end of the handle. The interior of the suction tube 2 forms a suction channel. The suction transition tube 4 is coaxially connected to the suction tube 2 and the suction connection tube 11, and is adjustable for telescopic movement.

[0068] The irrigation branch is used to irrigate the surgical area during surgery. It comprises an irrigation tube 3 at the distal end of the handle, an irrigation transition tube 5 within the handle, and an irrigation connection tube 12 at the proximal end of the handle. The irrigation tube 3 is sheathed around the suction tube 2. A gap exists between the outer wall of the suction tube 2 and the inner wall of the irrigation tube 3, forming an irrigation channel. The irrigation channel and the suction channel are not connected. The irrigation transition tube 5 is independently provided from the suction transition tube 4.

[0069] The push control assembly is arranged on the handle and is connected to the suction transition tube 4. The push control assembly is adapted to push the suction transition tube 4 and the suction tube 2 to move distally when performing the suction action so that the suction channel protrudes from the flushing channel.

[0070] The aforementioned irrigation and suction device has independent irrigation and suction channels, effectively preventing cross-contamination between the two channels. The suction and irrigation branches are fluidically isolated from each other. The irrigation tube is sheathed within the suction tube and separated from the irrigation tube by a radial gap 18. This radial gap forms part of the irrigation branch, freeing the interior space of the suction tube from the irrigation tube. This allows for smoother suction operations and reduces the risk of blockage.

[0071] When suctioning waste from a surgical area, the control assembly can be directly used to push the suction transition tube 4 and the suction tube 2 toward the distal end, causing the flushing tube 3 and the suction tube 2 to be misaligned, with the suction channel protruding from the flushing channel. Consequently, during the suction operation, the tissue and blood clots to be suctioned do not come into contact with the flushing tube 3, preventing them from entering the flushing tube 3 and being flushed back into the human body through the flushing channel, causing secondary contamination. The flushing branch and the suction branch are completely independent of each other in terms of fluid flow, preventing the possibility of the suctioned liquid being flushed back into the surgical wound, increasing the risk of secondary infection.

[0072] Since the diameter or volume of the part entering the human body is smaller, more instruments can be accommodated in the surgical incision channel for simultaneous use during surgery.

[0073] The pipelines of the present invention are all sealed and sterilely connected, which reduces the chance of infection. The streamlined design of the handle fully meets the requirements of ergonomics.

[0074] As a specific embodiment, the suction transition tube 4 includes a telescopic tube 41, a middle connecting tube 42, and a suction connecting tube 43, which are sequentially connected from the distal end to the proximal end. The telescopic tube 41 is connected to the suction tube 2, and the suction connecting tube 43 is connected to the suction connecting tube 11. In this embodiment, the telescopic tube 41 is a telescopic steel tube, and the expansion and contraction of the suction transition tube 4 is mainly achieved by the expansion and contraction of the telescopic tube.

[0075] In a specific embodiment, the push control assembly includes a push button 10, which is connected to the central connecting tube 42 via a connecting groove. A slideway is provided on the handle to facilitate movement of the push button 10. When the operator presses the push button 10, it directly moves the suction transition tube 4, thereby causing the telescopic tube within the suction transition tube 4 to extend and retract, thereby moving the suction tube 2.

[0076] As a further improved embodiment, a frame 61 is provided inside the handle, and a telescopic tube holding chamber 6 suitable for holding the telescopic tube 41 is enclosed between the frame 61 and the handle, and the telescopic tube holding chamber 6 is sealed. A pair of through holes are provided on the frame 61, and the two ends of the telescopic tube 41 are respectively fitted into the through holes by means of a sliding seal of a silicone ring. More specifically, the silicone ring is a T-shaped silicone ring 64, and the T-shaped silicone ring 64 has a large cylindrical rubber ring section and a small cylindrical rubber ring section, and the large cylindrical rubber ring section is slidably sealed with the through hole. In addition, the telescopic tube holding chamber 6 is sealed between the sealing ring 62 and the inner wall of the handle. Because the frame 61 is provided in this embodiment, it can be ensured that the telescopic tube 41 is always in the same straight line when telescoping and extending, and will not deviate.

[0077] The suction branch in this embodiment is connected to the suction connecting pipe through the assembly of the telescopic tube, the middle connecting pipe 42, and the suction connecting pipe to form a suction channel. The suction channel is sealed by a T-shaped silicone ring and can slide.

[0078] As a further improved embodiment, an opening 65 is provided on the side wall of the telescopic tube 41, and the opening 65 is placed in the telescopic tube holding chamber 6. The handle is provided with a pressure regulating hole 63 which is respectively connected to the telescopic tube holding chamber 6 and the atmosphere, and the pressure regulating hole 63 is suitable for adjusting the air pressure on the suction branch. The pressure regulating hole 63 is in the shape of a water droplet, which can realize stepless adjustment of the suction pressure. When adjusting the pressure inside the suction tube 2, the operator can manually press the pressure regulating hole 63, and control the opening size of the pressure regulating hole 63 by moving the finger, thereby controlling the negative pressure attraction force of the suction tube. The suction force of the suction tube 2 can be manually adjusted according to different application scenarios. In all operations, the operator can adjust the size of the attraction force in the suction channel by blocking the pressure regulating hole 63, which is very convenient to control.

[0079] The suction tube is sealed with the pressure regulating hole 63 outside the handle housing by a sealing ring and is not connected to the flushing pipeline. The staggered arrangement of the suction channel and the flushing channel can effectively prevent the suctioned penetrating material from entering the flushing pipe and causing secondary contamination.

[0080] As a further improved embodiment, the flushing transition pipe 5 is a flushing hose. A water control assembly 7 is provided on the handle to control the opening and closing of the flushing hose. In this embodiment, the water control assembly 7 directly presses the flushing transition pipe 5 when in operation, thereby controlling the opening and closing of the flushing transition pipe 5.

[0081] More specifically, if Figure 6 As shown, the water control assembly includes a lower cover spring seat, a flush button 71 and a spring structure 75 disposed between the lower cover and the button. Figure 5 As shown, the flushing transition pipe 5 is fixed to the handle at its proximal end via a flushing button 71. The flushing button has a cylindrical through hole suitable for passing the flushing hose. The flushing button is provided on the handle to effectively adjust the on / off and flow rate of the flushing channel and is easy to operate.

[0082] Blocks 73 are provided on both sides of the flush button 71. A flush button receiving compartment is provided on the upper housing of the handle, from which the flush button 71 extends. Blocks 73 are provided on both sides of the flush button 71. The flush button 71 is engaged with the clamping slot 72 via the clamping blocks 73 and can move up and down within the clamping slot 72. A protrusion 74 is provided at the bottom end of the flush button 71, and the protrusion 74 is arranged opposite to the spring structure 75.

[0083] The flush button and handle are constructed independently of each other, or the lower cover spring seat is formed by the handle structure itself. The lower cover spring seat is a cylindrical structure with a window, and the button is a cylindrical structure with a through-hole. The button is partially embedded in the base, and the window and through-hole are aligned with each other. The flush hose passes through the spring structure 75. The lower cover spring seat and button cooperate with each other through the spring structure.

[0084] like Figure 8 As shown, due to the spring structure, the flush button is normally in the pop-up state, so under normal circumstances, the flush button hooks the flush channel to put it in the normally closed state; Figure 7 As shown, by pressing the flush button, the flush channel is restored to achieve flushing.

[0085] As a further improved embodiment, both the suction tube 2 and the irrigation tube 3 are elastic tubes. More specifically, the irrigation tube 3 is made of a flexible metal tube, while the suction tube 2 is made of spring steel. This allows for flexible bending of both the irrigation and suction tubes, facilitating smooth access and completion of minimally invasive surgeries through various access points, meeting a wider range of intraoperative needs. Both the suction tube 2 and the irrigation tube 3 are wrapped in heat-shrink tubing.

[0086] As a further improved implementation method, Figure 4 As shown, the proximal end of the irrigation tube 3 is sealed and secured within the handle via an irrigation tube rubber coating 15. This coating 15 has a cylindrical channel for the irrigation transition tube 5, which is directly positioned within the cylindrical channel. The irrigation tube rubber coating 15 comprises a first irrigation tube rubber coating located on the outside of the handle and a second irrigation tube rubber coating located on the inside. The first and second irrigation tube rubber coatings are secured within the accommodating cavity of the handle housing by latching. The first irrigation tube rubber coating is sealed to the handle housing, while the second irrigation tube rubber coating forms a sliding seal with the suction transition tube 4. The second irrigation tube rubber coating is also provided with a cylindrical channel 17.

[0087] As a further improved embodiment, the distal end of the suction tube 2 and / or the flushing tube 3 is provided with an arc structure, the contact between the distal end of the suction tube 2 and / or the flushing tube 3 and the tissue is smoother, and the peripheral sharp edges of the front end surface are all rounded and blunted to prevent tissue cutting, which can prevent the front end of the suction tube 2 and / or the flushing tube 3 from scratching the tissue.

[0088] Example 2

[0089] Currently commonly used flushers, aspirators, and bipolar coagulation consumables usually only have a single function, and the three need to be operated in turn when in use. This increases the surgical procedures, increases the labor intensity of medical staff, wastes surgical time, and increases surgical risks.

[0090] In order to solve the above technical problems, this embodiment discloses a bipolar electrocoagulation device, such as Figures 1 to 12 As shown, it includes a first contact spring 8, an insulating coating 16, a second contact spring 9 and the flushing and suction device in Example 1.

[0091] It should be noted that the suction tube 2, the suction transition tube 4 and the flushing tube 3 in Example 1 are all conductive tubes. The suction tube 2 is an external electrode rod, and the flushing tube 3 is an internal electrode rod.

[0092] The first contact spring 8 is arranged inside the handle, one end of the first contact spring 8 is in conductive contact with the flushing tube 3, and the other end of the first contact spring 8 is connected to the power supply.

[0093] An insulating coating 16 is applied to the suction transition tube 4. Specifically, a section of the central connecting tube 42 of the suction transition tube 4 is provided with a groove, within which the insulating coating 16 is located. The insulating coating 16 serves to isolate the suction transition tube 4 from the second contact spring 9, thereby controlling the overall operating state of the device.

[0094] The second contact spring 9 is disposed inside the handle and at the distal end of the insulating coating 16 . The second contact spring 9 is connected to a power source.

[0095] The interior of the handle housing is provided with a contact spring slot, which can stably place the contact spring.

[0096] The above-mentioned bipolar coagulation device can control whether the entire device is connected to the power supply by pushing the control component, and then switch the use status of the device. It can be used as a flushing and suction device, and can also be used as a bipolar coagulation consumable. It integrates suction, flushing, and coagulation into one, which greatly reduces the surgical procedures, saves surgical time, and reduces surgical risks.

[0097] When the push control assembly pushes the suction tube 2 and suction transition tube 4 toward the distal end, the insulating coating 16 contacts the second contact spring 9. The push button is pushed away from the electrode rod end, and the contact spring is in the insulating layer, disconnecting the circuit and disconnecting the entire device from power. The irrigation and suction channels are now misaligned. The suction channel protrudes from the irrigation channel, and the device is now flushing and suctioning.

[0098] When the control assembly pushes the suction tube 2 and suction transition tube 4 proximally, the irrigation channel aligns with the suction channel, the suction transition tube 4 contacts the second contact spring 9, and the contact spring distal to the electrode rod end is now conductively connected to the suction channel. The entire device is now in an electrocoagulation state. More specifically, the contact spring distal to the electrode rod end is conductively connected to the suction channel, while the contact spring proximal to the electrode rod end is conductively connected to the irrigation channel. The circuit forms a bipolar loop through the wires, the suction channel, the body, the irrigation channel, and the wires, thereby achieving coagulation.

[0099] The product of the present invention has an anti-accidental touch mechanism. When the push button is pushed out, the flushing channel and the suction channel form a step position. At this time, the shape of the electrode rod is suitable for flushing and suction. Figure 10 As shown. At this time, the circuit is disconnected to prevent accidental stepping on the foot switch of the electrosurgical unit during surgery, which may cause accidental tissue damage. When the push button is pushed in, the flushing channel and the suction channel are flush. At this time, the shape of the electrode rod is suitable for electrocoagulation, such as Figure 11 At this point, the insulating section moves backward, and the circuit can form a loop.

[0100] The product of the present invention integrates the functions of flushing, suction, and electrocoagulation, and can perform all functions with one hand, thus reducing the use of instruments and simplifying the surgical process.

[0101] The product of the present invention is a disposable product, which prevents intraoperative infection caused by repeated sterilization.

[0102] As a further improved embodiment, the suction tube 2 is sheathed with a suction tube insulating tube 13, and the irrigation tube 3 is sheathed with an irrigation tube insulating tube 14. The irrigation tube insulating tube 14 provides insulation. The suction tube insulating tube 13 prevents electrical conduction between the outer wall of the suction tube 2 and the inner wall of the irrigation tube 3. During coagulation, the circuit is maintained solely through the bipolar circuit: electrical wire → suction channel → body → irrigation channel → electrical wire.

[0103] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
