Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically relating to an electrocoagulation and suction device. Background Technology

[0002] In laparoscopic minimally invasive surgery, tissue electrocoagulation and hemostasis, along with surgical field cleaning, are core aspects of surgical operation, safety, and efficiency. Currently, in clinical practice, the electrocoagulation cutter and irrigation / suction device are used separately as independent instruments, leading to significant deficiencies in the operational process.

[0003] Traditional surgery requires frequent switching between the electrocoagulation cutter and the irrigation suction device, with each switch taking approximately 1.5-3 seconds (2023 Intraoperative Action Analysis Study in the *Journal of Laparoscopic Surgery*). Especially in emergency hemostasis scenarios, this delay can increase blood loss by 20-40 ml (data from the *Chinese Journal of Surgery*). Furthermore, using two instruments simultaneously occupies more of the surgical channel (e.g., the laparoscopic trocar), making it harder to expose the operating space and affecting surgical procedures. Additionally, traditional instruments cannot achieve simultaneous electrocoagulation hemostasis and irrigation suction, resulting in continuous bleeding from the wound during the time interval between switching from the suction device to the electrocoagulator, hindering wound observation and making manipulation difficult, thus impacting effectiveness and accuracy. Moreover, electrocoagulation smoke (mainly composed of water vapor and fat particles) reduces the clarity of the laparoscopic image by 60-70% (image grayscale analysis), and traditional instrument switching and smoke suction require 3-5 seconds to restore the field of vision.

[0004] While there are integrated attempts in the market (such as "electrocoagulation-suction" combined devices), they generally suffer from the following drawbacks. Suction and irrigation share a single tube and channel, and the two functions can only be used intermittently. It is impossible to use the irrigation function while continuously suctioning, which greatly limits the application scenarios. In addition, the existing irrigation mechanisms are all laminar flow or drip mode, lacking the ability to target debridement by utilizing fluid dynamics optimization, resulting in a large irrigation volume but inadequate irrigation of the target points.

[0005] This utility model addresses the aforementioned industry pain points, breaking through the limitations of traditional "split-type" and "shared pipeline" designs. Through four core technologies—dual-tube coaxial fluid coupling, central three-way topology, mechanical pressurized jet, and rotational conductive linkage—it fills the technological gap in "dynamic collaborative debridement-hemostasis-manipulation" in the minimally invasive field, providing key equipment support for precise minimally invasive surgery. Utility Model Content

[0006] In summary, to overcome the shortcomings of the existing technology, this utility model provides an electrocoagulation suction device that integrates electrocoagulation cutting, jet flushing and suction functions.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electrocoagulation suction device, comprising a housing, the housing including a gun body and a handle, a conductive rod disposed at the front end of the gun body, an insulating layer disposed around the conductive rod, an electrocoagulation working head disposed at the front end of the conductive rod, the conductive rod being hollow, a flushing tube being sleeved inside the conductive rod, the gap between the inner wall of the conductive rod and the outer wall of the flushing tube forming a suction channel, a suction flushing device and an electrocoagulation and electrocutting device disposed within the housing, and a conductive part for connecting to the electrocoagulation and electrocutting device and a connecting part for connecting to the suction flushing device being disposed at the rear end of the conductive rod, the conductive part being connected to the... The electrocoagulation and electrocutting device is electrically connected, with the conductive part disposed between the connecting part and the insulating layer. The suction and rinsing device includes a three-way connecting pipe and a rinsing mechanism. The three-way connecting pipe includes a first port connected to the connecting part, a second port connected to the rinsing mechanism, and a third port for connecting to the negative pressure suction mechanism. The third port is disposed between the first port and the second port. The rinsing pipe passes through the first port and the second port and is connected to the rinsing mechanism. The rear end of the gun body is provided with a suction pipe for connecting to the negative pressure suction mechanism. The suction pipe and the third port are connected by a connecting pipe and an adjustment switch for controlling the suction force is provided.

[0008] By adopting the above technical solution, compared to existing electrocoagulation and aspiration devices that require switching between flushing and suction, this solution uses a dual-tube approach. The flushing tube is located inside the conductive rod, and suction is performed through the gap between the flushing tube and the inner wall of the conductive rod, while flushing is performed through the flushing tube. This allows for simultaneous use of both functions, with flushing and suction working at the same time, providing real-time cleaning of the surgical field and improving operational precision. The gun-style design facilitates one-handed operation, enabling multiple functions such as suction, flushing, electrocoagulation, and electrocautery to be performed with a single instrument, avoiding frequent instrument changes and simplifying operation. During electrocautery, simultaneous flushing opens up tissue gaps, allowing the electrocoagulation head to more accurately expose the target structure, improving cutting efficiency. Simultaneously, the suction system removes debris promptly, reducing secondary bleeding. The suction strength is controlled by rotating an adjustment switch, allowing for precise operation and making it more convenient and stable to use.

[0009] This embodiment further includes the following configuration: the rinsing mechanism comprises a pressing component, a connecting pipe, a water inlet pipe, and a pressure check valve controlled by the pressing component. The connecting pipe includes an outlet end connected to the rinsing pipe via a connecting pipe and an inlet end connected to the water inlet pipe. The water inlet pipe includes an inlet for connecting to the rinsing liquid. The inlet is located at the rear end of the housing. The pressure check valve is located inside the connecting pipe. The pressing component includes a pressing part located at the front end of the handle and a pressure rod with one end located inside the connecting pipe.

[0010] By adopting the above technical solution, manually pressing the pressing part causes the air rod to drive the piston to compress the liquid in the connecting pipe, generating high pressure. This causes the pressure check valve to open the water outlet, allowing the flushing fluid to be transferred from the connecting pipe to the flushing pipe. When the pressing part is released, the air rod automatically resets under the action of the spring, generating suction. Water is then drawn from the inlet pipe into the connecting pipe from the inlet end. At this time, the spring presses against the valve body to prevent backflow. Compared with existing electrocoagulation flushing devices, the existing water output is closer to running water than flushing water. Due to the design inside the connecting pipe, operating the pressing part gives the flushing pipe water a certain air pressure, causing the flushing pipe water to form a jet under pressure, resulting in more efficient flushing efficiency and effect. At the same time, flushing can quickly reduce the local high temperature generated by electrocoagulation. The water output is jet-shaped, more targeted, rather than scattered outward flow.

[0011] This embodiment further includes a one-way valve at the inlet pipe port.

[0012] By adopting the above technical solutions, zero backflow can be achieved, improving the safety and cleanliness of the surgery.

[0013] This embodiment further includes the following configuration: the first pipe opening is provided with a first sealing plug, the first sealing plug is provided with a through hole adapted to the connecting part, the second pipe opening is provided with a second sealing plug, the second sealing plug is provided with a through hole adapted to the flushing pipe.

[0014] By adopting the above technical solution, the sealing between the first and second ports of the tee connector is strengthened, making the suction at the third port more stable.

[0015] This embodiment further includes a one-way valve installed between the third port and the suction tube.

[0016] By adopting the above technical solutions, suction backflow is avoided, thus improving the safety and cleanliness of the surgery.

[0017] This embodiment further includes the following configuration: the electrocoagulation and electrocutting device includes a control button, the control button has a contact at its rear end, a circuit board and a power supply line connected to the circuit board are located behind the control button, and the power supply line is electrically connected to the conductive rod.

[0018] By adopting the above technical solution, the control buttons can control the electrocoagulation and electrocution operations respectively.

[0019] This embodiment further includes the following features: a cut surface is provided at the front end of the electrocoagulation working head, and a triangular cut is provided on the side wall of the electrocoagulation working head.

[0020] By adopting the above technical solution, the electrocoating working head adopts a sloping triangular design, which will not obstruct the view and makes the "scraping and suction" operation more convenient. The side wall is provided with triangular cuts, which increases the water absorption area.

[0021] This embodiment further includes an elastic conductive sheet that abuts against the conductive part, and the elastic conductive sheet is connected to the power supply line.

[0022] By adopting the above technical solution, compared with fixed lines, in this technical solution, the conductive rod contacts the elastic conductive sheet when rotating, the contact is stable, and the power supply line is avoided from getting tangled. The structure is simple and easy to use.

[0023] This embodiment further includes the following configuration: a rotating wheel for driving the conductive rod to rotate is provided at the front end of the gun body, and the connecting part is rotatably connected to the first pipe opening.

[0024] By adopting the above technical solution, the rotary wheel can be easily operated with one finger, and the cutting direction of the electrocoagulation working head can be controlled by the rotary wheel, which facilitates electrocoagulation and electrocutting operations.
