Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to a multipurpose electrode for transurethral prostate surgery. Background Technology

[0002] Transurethral prostate surgery (such as transurethral resection of the prostate, TURP) is a common method for treating benign prostatic hyperplasia (BPH). Traditional surgical electrodes are often single-function, typically only capable of either cutting or coagulation. Frequent electrode changes during the procedure increase surgical time and complexity. Furthermore, the design of traditional electrodes causes significant thermal damage to surrounding tissues, leading to a higher risk of postoperative complications. Therefore, there is an urgent need for a multifunctional, efficient, and safe electrode to improve surgical efficiency and patient safety. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-purpose electrode for transurethral prostate surgery that can perform multiple functions such as cutting, coagulation and hemostasis, while reducing thermal damage to surrounding tissues and improving surgical efficiency and safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multi-purpose electrode for transurethral prostate surgery includes an electrode head, an electrode rod, and a connecting part; the electrode head has a cutting part at the front end and a coagulation part at the rear end; both the electrode head and the electrode rod are hollow structures with cooling medium channels and current conduction lines inside; the connecting part includes a power interface and a cooling medium interface.

[0005] Furthermore, the electrode tip has multiple micropores on its surface for releasing cooling medium. The cutting section features a sharp edge design, while the coagulation section features a smooth surface design.

[0006] The outer surface of the electrode rod is coated with a diamond-like carbon coating with a thickness of 1 to 10 micrometers. This coating provides good anti-adhesion properties, reduces tissue adhesion, and improves surgical efficiency, while also providing good insulation properties to prevent current leakage or unnecessary damage to surrounding tissues.

[0007] The electrode head and the electrode rod are detachably connected.

[0008] The multi-purpose electrode for transurethral prostate surgery of the present invention has the following advantages: Multifunctional integration: Cutting, coagulation and cooling functions are integrated into one, reducing the number of electrode changes during surgery and improving surgical efficiency; (2) Reduce thermal damage: Reduce the temperature of the surgical area by using a cooling medium to reduce thermal damage to surrounding tissues; (3) High safety: The insulation layer design reduces current leakage and lowers the risk of surgery.

[0009] (4) Detachable design: The electrode head is replaceable to adapt to different surgical needs and reduce the cost of use. Attached Figure Description

Detailed Implementation

[0012] The following detailed description of specific embodiments of the transurethral prostate surgery multipurpose electrode of the present invention, in conjunction with the accompanying drawings, provides a detailed explanation.

[0013] Combination Figures 1-4 The multi-purpose electrode for transurethral prostate surgery of the present invention includes an electrode head 1, an electrode rod 2, and a connecting part 3; the front end of the electrode head 1 is provided with a cutting part 11 and the rear end is provided with a coagulation part 12; both the electrode head 1 and the electrode rod 2 are hollow structures, and the interior is provided with cooling medium channels (14, 21) and current conduction lines (15, 22); the connecting part 3 includes a power interface 31 and a cooling medium interface 32.

[0014] like Figure 2 As shown, Figures 1-3 The electrode head 1 has multiple micropores 13 on its surface for releasing cooling medium. The cutting section 11 has a sharp edge design, while the coagulation section 12 has a smooth surface design.

[0015] like Figure 3 As shown, Figure 4 As shown, the outer surface of the electrode rod 2 is coated with a diamond-like carbon coating 23, the thickness of which is 1-10 micrometers. This coating provides both good anti-adhesion properties, reducing tissue adhesion and improving surgical efficiency, and good insulation properties to prevent current leakage or unnecessary damage to surrounding tissues. The electrode rod 2 has a cooling medium channel 21 and a current conduction line 22 inside.

[0016] The electrode head 1 and the electrode rod 2 are detachably connected, for example, by a snap-fit ​​structure.

[0017] When using the multi-purpose electrode for transurethral prostate surgery of the present invention, first check the equipment: ensure that the electrode head 1, electrode rod 2, and connecting part 3 are intact and the insulation layer 23 is undamaged; then connect the power supply and cooling medium: connect the power interface 31 to the power output terminal of the electrosurgical equipment, and connect the cooling medium interface 32 to the cooling medium supply system; next, check the cooling medium: ensure that there is sufficient cooling medium in the cooling medium supply system, and check that the cooling medium channels (14, 21) are unobstructed; then, assemble the electrode: connect the electrode head and electrode rod: connect the electrode head 1 and electrode rod 2 through the snap-fit ​​structure to ensure a firm connection; And check the current conduction circuit: ensure that the current conduction circuit (15, 22) is connected normally and there is no short circuit or open circuit; finally, perform the surgical operation: (1) Insert the electrode: insert the assembled electrode into the prostate surgical site through the urethra; (2) Start the cooling system: turn on the cooling medium supply system, so that the cooling medium is released from the micro-hole 13 of the electrode head 1 through the cooling medium channel (14, 21) to reduce the temperature of the surgical site and reduce tissue damage; (3) Start the power supply: turn on the electrosurgical equipment and adjust the current intensity as needed; (4) Cutting operation: use the cutting part 11 at the front end of the electrode head 1 to cut the tissue. The sharp edge design of the cutting part 11 helps to cut accurately; (5) Coagulation operation: use the coagulation part 12 at the rear end of the electrode head 1 to stop bleeding. The smooth surface design of the coagulation part 12 helps to transmit the current evenly and promote coagulation; (6) Postoperative treatment: turn off the power supply and cooling system, separate the electrode head 1 from the electrode rod 2 for easy cleaning and disinfection.

[0018] The multi-purpose electrode for transurethral prostate surgery of the present invention integrates cutting, coagulation and cooling functions, reducing the number of electrode replacements during surgery and improving surgical efficiency; it reduces the temperature of the surgical area by using a cooling medium, reducing thermal damage to surrounding tissues; the insulation layer design reduces current leakage and lowers surgical risks; and the electrode head is replaceable to adapt to different surgical needs, reducing usage costs.

[0019] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent process transformations made using the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
