Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a multifunctional surgical dissecter that integrates argon coagulation and contact cutting. Background Technology

[0002] In open surgeries involving solid organs or highly vascularized tissues such as the liver, spleen, thyroid gland, and gynecological organs, effective hemostasis is crucial for ensuring a clear surgical field, minimizing intraoperative blood loss, and reducing postoperative complications. Currently used surgical hemostasis tools have the following limitations: 1. Monopolar or bipolar electrocoagulation devices: These instruments require direct contact between the electrode tip and human tissue to conduct high-frequency current, achieving tissue coagulation or cutting. During hemostasis, especially when dealing with large areas of oozing, the electrode tip is prone to adhering to the heated and carbonized tissue. When the instrument is removed, the adhered eschar is torn off, potentially leading to secondary bleeding, forcing the surgeon to perform repeated hemostasis and prolonging the operation time. Furthermore, the high energy density at the contact point can easily cause excessive tissue carbonization and deep thermal damage, which is detrimental to postoperative wound healing.

[0003] 2. Independent argon beam solidification system: Argon Plasma Coagulation (APC) technology uses ionized argon gas as a conductive medium to guide high-frequency current to the tissue surface, achieving non-contact, large-area, superficial, and uniform coagulation. Because it does not directly contact the tissue, it fundamentally avoids instrument adhesion problems, and its shallow heat penetration depth results in less tissue damage. However, traditional APC devices are typically independent jet probes or handles with limited functionality. When surgery requires a rapid switch from large-area argon coagulation to precise point-like hemostasis, tissue separation, or cutting, the surgeon must change instruments. This process disrupts the continuity of the surgery, increases the number of steps, and affects surgical efficiency.

[0004] Therefore, there is an urgent clinical need for a surgical instrument that can intelligently and rapidly integrate non-contact argon coagulation with contact electrosurgery to address the aforementioned technical challenges. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional surgical dissecter that integrates argon coagulation and contact cutting in order to solve the problems mentioned above.

[0006] On the one hand, in order to achieve the above objectives, the present invention adopts the following technical solution: a multifunctional surgical dissecter integrating argon coagulation and contact cutting, comprising: handle; A telescopic surgical electrode is fixedly connected inside the handle, and one end of the telescopic surgical electrode extends to the outside of the front end of the handle. An argon gas excitation catheter is slidably connected inside the handle, and one end of the argon gas excitation catheter extends to the outside of the front end of the handle. The argon gas excitation catheter is parallel to the telescopic surgical electrode. A sliding drive is connected to the handle, and the sliding drive is connected to and drives the argon excitation conduit; A control circuit board is disposed inside the handle and is electrically connected to the argon gas excitation catheter and the telescopic surgical electrode.

[0007] As a further description of the above technical solution: The sliding drive component is a slider, and a guide groove is provided on the handle. The sliding drive component is connected to the argon gas excitation conduit through a connecting rod, and the sliding drive component is slidably connected in the guide groove.

[0008] As a further description of the above technical solution: The sliding drive component is a dial, which is rotatably connected to the handle. A gear is fixedly connected to the sliding drive component, and a rack is fixedly connected to the argon gas excitation conduit. The gear meshes with the rack.

[0009] As a further description of the above technical solution: The sliding drive is a miniature linear motor. The sliding drive is fixedly connected to the handle and electrically connected to the control circuit board. The telescopic end of the sliding drive is fixedly connected to the argon gas excitation conduit.

[0010] As a further description of the above technical solution: An insulating layer is provided between the argon gas excitation catheter and the telescopic surgical electrode.

[0011] As a further description of the above technical solution: The front end of the argon gas excitation conduit is inlaid with a ceramic insulating head.

[0012] As a further description of the above technical solution: The control circuit board switches the high-frequency current output path between the argon gas excitation catheter and the telescopic surgical electrode according to the extension and retraction of the telescopic surgical electrode.

[0013] As a further description of the above technical solution: The handle is equipped with a position sensor to detect the real-time position of the telescopic surgical electrode and feed the signal back to the control circuit board.

[0014] As a further description of the above technical solution: The handle is equipped with multiple control knobs, which are electrically connected to the control circuit board to realize one or more of the functions of mode selection, high-frequency energy adjustment and argon flow control.

[0015] On the other hand, in order to achieve the above objectives, the present invention adopts the following technical solution: a surgical system, including a multifunctional surgical dissecter integrating argon coagulation and contact cutting; and further including a high-frequency electrosurgical energy platform and an argon gas source, wherein the multifunctional surgical dissecter is connected to the high-frequency electrosurgical energy platform and the argon gas source through a double parallel electrical circuit.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by integrating two core electrosurgical functions, the surgeon can instantly switch between contact anatomy and non-contact hemostasis with a simple action, without the need to exchange instruments, which greatly optimizes the surgical procedure, shortens the operation time, achieves a high degree of functional integration, and makes the operation smooth and efficient.

[0017] 2. In this invention, by using a non-contact argon coagulation mode when treating large-area or diffuse bleeding, the electrode does not come into contact with the tissue at all, fundamentally eliminating secondary tissue damage and bleeding caused by adhesion, improving the reliability of hemostasis, and completely solving the problem of adhesion.

[0018] 3. In this invention, argon plasma coagulation has the characteristics of being superficial and uniform, which can effectively reduce thermal necrosis and excessive carbonization of deep tissues, thereby creating better conditions for wound healing, and is expected to reduce postoperative pain and improve healing quality, resulting in less tissue trauma and facilitating healing.

By pushing the sliding drive component 4 to slide along the guide groove 6, the argon gas excitation conduit 3 can be manually pushed to slide in the handle 1. The sliding drive component 4 is a dial wheel. The sliding drive component 4 is rotatably connected to the handle 1. A gear is fixedly connected to the sliding drive component 4. A rack is fixedly connected to the argon gas excitation conduit 3. The gear meshes with the rack. Rotating the sliding drive component 4 will drive the gear to rotate. The gear drives the rack meshing with it to move, thereby driving the argon gas excitation conduit 3 to slide within the handle 1. The sliding drive component 4 is a miniature linear motor. The sliding drive component 4 is fixedly connected to the handle 1 and electrically connected to the control circuit board 5. The telescopic end of the sliding drive component 4 is fixedly connected to the argon gas excitation conduit 3, which facilitates the electric push of the argon gas excitation conduit 3 to slide within the handle 1.

[0027] Working principle: First, when tissue dissection or precise point-like hemostasis is required, the surgeon manually pulls out the telescopic surgical electrode 2. At this time, the argon gas excitation catheter 3 is in the retracted state. The position sensor detects the real-time position of the telescopic surgical electrode 2 and feeds the signal back to the control circuit board 5. By operating the control knob 7, the appropriate mode and power are selected for contact operation. At this time, the control circuit board 5 selects the telescopic surgical electrode 2 as the high-frequency current output path for contact cutting and coagulation. Second, when encountering large-area wound bleeding that requires rapid hemostasis, the surgeon pushes back the telescopic surgical electrode. Electrode 2 retracts, while the sliding drive 4 extends the argon excitation catheter 3. The position sensor detects the real-time position of the telescopic surgical electrode 2 and feeds the signal back to the control circuit board 5. The control circuit board 5 selects the argon excitation catheter 3 as the high-frequency current output path. Finally, the surgeon presses the foot switch of the high-frequency electrosurgical energy platform, and the argon gas source supplies gas. The high-frequency current is applied to the argon excitation catheter 3. The argon gas is ionized in front of the ceramic insulated head to form a light blue argon plasma beam, which is sprayed onto the tissue surface to achieve uniform non-contact coagulation. The entire process does not require changing instruments.
