DETAILED DESCRIPTION

[0025] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] Please refer to Figure 1 The present invention relates to a multifunctional surgical forceps, which is intended to improve surgical efficiency and reduce surgical difficulty. The following is a detailed description of the specific implementation of the multifunctional surgical forceps of this embodiment.

[0027] First, the multifunctional surgical forceps of this embodiment include a first body 1 and a second body 2, which are connected by a hinge 11, allowing the first body 1 and the second body 2 to rotate relative to each other. The tail ends of the first body 1 and the second body 2 are connected to a wire 6, which is used to connect to the plasma radio frequency host to achieve energy transmission and control.

[0028] The front end of the first clamp body 1 is provided with a first jaw 4, and the front end of the second clamp body 2 is provided with a second jaw 3. When the first clamp body 1 and the second clamp body 2 rotate relative to each other, the first jaw 4 and the second jaw 3 can work together to achieve the functions of clamping, cutting and coagulating tissue.

[0029] Please refer to Figure 2-3 In detail, the first jaw 4 includes a first jaw frame 41, a first electrode sheet 42, and a blade 43. The first jaw frame 41 serves as a support and includes a first jaw frame 411 and a first jaw insulation layer 412 disposed on the surface of the first jaw frame 411. The first jaw insulation layer 412 is used to prevent current from being directly transferred to the jaw frame 411, thereby ensuring safety during surgery.

[0030] The first electrode sheet 42 is positioned on the inner side of the first jaw frame 41, facing the second jaw 3. The first electrode sheet 42 is connected to the plasma RF host via a wire 6 for both receiving and transmitting energy. The inner side of the first electrode sheet 42 is designed to be serrated. This serrated design not only increases the contact area between the electrode sheet and the tissue but also enhances grip stability and firmness.

[0031] The blade 43 is rotatably connected to the front end of the first jaw frame 41, allowing it to rotate relative to the first jaw frame 41. The rotational connection of the blade 43 is achieved via a hinge, which has a pin 44 inside. The surface of the blade 43 is provided with a blade insulation layer 431, which prevents direct current transfer to the blade 43, thereby preventing adhesion during the cutting process.

[0032] The second jaw 3 includes a second jaw frame 31 and a second electrode pad 32. The second jaw frame 31 serves as a support and includes a second jaw frame 311 and a second jaw insulation layer 312 disposed on the surface of the second jaw frame 311. The second jaw insulation layer 312 also prevents current from being directly transferred to the jaw frame 311, ensuring safety during surgery.

[0033] The second electrode sheet 32 ​​is positioned on the inner side of the second jaw frame 31, facing the first jaw 4. The second electrode sheet 32 ​​is connected to the plasma RF host via a wire 6 for both receiving and transmitting energy. Similar to the first electrode sheet 42, the inner side of the second electrode sheet 32 ​​is also designed with teeth to enhance grip stability and securement.

[0034] To achieve the cutting function, this embodiment includes a cutting button 5 on the side of the second forceps body 2. The tail end of the cutting button 5 is connected to a connecting rod 7, the other end of which is connected to a blade 43. When tissue cutting is required, the medical professional presses the cutting button 5, which rotates the blade 43 via the connecting rod 7, thereby achieving the cutting function. The surface of the connecting rod 7 is provided with a connecting rod insulation layer 71 to prevent direct current transfer to the connecting rod 7, ensuring safety during the operation.

[0035] During operation, medical personnel can manually pinch the first and second jaws 1, 2 together, utilizing the hinge 11 and lever to achieve a gripping function. The gripping function is achieved by the tooth-shaped design of the first and second electrode sheets 42, 32. The tooth-shaped design increases the contact area and friction between the electrode sheets and the tissue, making gripping more stable and reliable.

[0036] To achieve hemostasis, medical personnel press the coagulation button on the plasma RF main unit (part of a dual-output footswitch). The footswitch receives the coagulation signal and transmits it to the plasma RF main unit. The main unit then transmits energy via wire 6 to the first and second electrodes 42 and 32 of the forceps. This energy generates high-temperature plasma between the electrodes and the tissue, rapidly coagulating the tissue and achieving hemostasis.

[0037] To perform a cut, the medical professional simultaneously depresses the cut button (also part of the dual-output foot switch) on the plasma RF main unit, squeezes the first and second jaws 1 and 2, and simultaneously presses the cut button 5 on the second jaw 2. The foot switch receives the cut signal and transmits it to the plasma RF main unit. Upon receiving the signal, the main unit transmits energy via wire 6 to the first and second electrodes 42 and 32 of the forceps, while simultaneously transmitting a different energy level to the blade 43. The combined mechanical force and plasma RF energy cause the blade 43 to cut downward, effectively performing the cut.

[0038] To ensure smooth return of blade 43 during the cutting process, this embodiment incorporates a spring (not shown). This spring automatically returns blade 43 to its initial position after the cut is complete, allowing for the next cut. A special blade insulation layer 431 prevents sticking during the cutting process while ensuring effective return of blade 43.

[0039] The following is a description of a specific application scenario of the multifunctional surgical forceps of this embodiment:

[0040] During neurosurgery, medical staff need to use multifunctional surgical forceps to clamp brain tissue and cut it. First, the medical staff inserts the multifunctional surgical forceps into the surgical site, and manually pinches the first forceps body 1 and the second forceps body 2 together, using the tooth-shaped electrode sheet to clamp the brain tissue. Then, the medical staff steps on the coagulation button on the plasma radio frequency host to generate high-temperature plasma between the electrode sheet and the tissue to achieve hemostasis. Next, the medical staff steps on the cutting button and pinches the cutting button 5 at the same time, so that the blade 43 cuts down the brain tissue under the simultaneous action of mechanical force and plasma radio frequency energy. During the cutting process, the blade insulation layer 431 avoids adhesion problems, and the spring ensures that the blade 43 can automatically reset to its initial position after the cutting is completed. Finally, the medical staff continues to use the multifunctional surgical forceps to perform other surgical operations until the operation is completed.

[0041] In addition, in order to further optimize the performance and reliability of the multifunctional surgical forceps of this embodiment, the following improvements may be made:

[0042] Improve electrode design: Adding tiny bumps or grooves to the electrode's tooth structure increases the contact area and friction with the tissue, thereby improving grip stability and firmness. Alternatively, consider using electrodes made of different materials or coatings to enhance conductivity and biocompatibility.

[0043] Optimize the blade's structure and material: Consider using more advanced materials and technologies to manufacture the blade to improve its hardness, wear resistance, and corrosion resistance. At the same time, you can also optimize the blade's structure to reduce resistance and friction during cutting, improving cutting efficiency and precision.

[0044] Adding intelligent control functions: Some intelligent control functions can be added to the multifunctional surgical forceps, such as temperature monitoring and pressure monitoring. These functions can monitor key parameters during the operation in real time, providing medical staff with more accurate and timely surgical information, thereby further improving the safety and success rate of the operation.

[0045] Improve maintainability and durability: The structural design of multifunctional surgical forceps can be further optimized to make them easier to disassemble and clean. Furthermore, better materials and manufacturing processes can be used to increase their durability and service life. These improvements can reduce the maintenance and operating costs of surgical forceps and enhance their value in the medical field.

[0046] In summary, the multifunctional surgical forceps of this embodiment has broad application prospects and important promotion value. By continuously optimizing and improving its performance and reliability, its application effect in the medical field and social benefits can be further improved.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
