Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a low-temperature anti-adhesion radiofrequency plasma electrode for surgery and a use method thereof. BACKGROUND

[0002] The radiofrequency plasma electrode is a medical device for surgery, which is used for cutting, coagulating, hemostasis and ablation of tissue through radiofrequency energy and plasma technology.

[0003] At present, the conventional high-frequency electrosurgical instrument mainly relies on the Joule heating effect caused by the resistance of the current passing through the tissue during the tissue cutting process, so that the liquid in the tissue cells is instantaneously vaporized, thereby realizing separation. The local instantaneous temperature in this process is usually as high as 200-400°C, or even higher. Excessive heat effect will cause a series of clinical and operation problems, mainly including: 1. Severe tissue carbonization: high temperature denatures and carbonizes tissue protein, which not only affects healing, but also may increase the risk of postoperative infection; 2. Knife head adhesion to tissue: carbonized tissue is easy to adhere to the electrode knife head, resulting in reduced instrument efficiency, which needs to be cleaned frequently, affecting the continuity of the operation; 3. Large thermal damage width: high temperature is conducted to the surrounding tissue, causing unnecessary thermal damage, which poses a potential risk to important nerves, blood vessels and other structures; 4. Large amount of smoke generated during operation: a large amount of smoke is generated by the decomposition of high-temperature tissue, which blocks the surgical field and affects the operation accuracy, and may also affect the health of medical staff.

[0004] In view of the above problems, the common improvement ideas in the prior art mainly include two kinds: one is to coat a single anti-adhesion coating such as polytetrafluoroethylene (PTFE) on the surface of the electrode to reduce tissue adhesion; the other is to reduce the output power to reduce thermal damage. However, these solutions still have obvious limitations: Limitations of single anti-adhesion coating: although the traditional PTFE coating has certain anti-adhesion properties, it does not have the ability to actively regulate the radiofrequency energy, and it is difficult to optimize the energy transmission efficiency and maintain stable insulation and anti-adhesion performance in long-term use; Defects caused by reducing power: reducing power can reduce thermal damage, but often leads to reduced cutting efficiency and discontinuous cutting process, especially when dealing with large blood vessels or dense tissue, which cannot achieve rapid and effective cutting and coagulation combination, affecting the smoothness of the operation; Conflict between conductivity and insulation: in the same instrument, the electrode needs to have good conductivity to ensure energy transmission, and also needs to have reliable insulation in some areas to avoid short circuit or bypass thermal damage. The existing coating system is difficult to maintain this performance balance in a high-frequency alternating electric field for a long time, and is easy to cause electrical breakdown due to insufficient local dielectric strength, or coating degradation and peeling due to heat concentration.

[0005] Furthermore, in high-frequency and high-voltage working environments, existing coating materials are prone to local dielectric breakdown or heat concentration, which not only affects the service life of instruments but may also cause uneven energy release, increasing uncertain risks during surgery. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a surgical low-temperature anti-adhesion radiofrequency plasma electrode and its usage method.

The outer sides of the air jets and liquid spraying holes are respectively elastically rotatably mounted with blocking plates two and four. The inner side of the air inlets is elastically rotatably mounted with blocking plates one. When through hole two coincides with the liquid spraying hole, through hole one coincides with the air inlets and air jets.

[0014] A method for using a surgical low-temperature anti-adhesion radiofrequency plasma electrode, the method being applied to the surgical low-temperature anti-adhesion radiofrequency plasma electrode as described above, the method comprising the following steps: Step S1: Instrument preparation and startup. Connect the power cord and start the radio frequency energy generator through the control component to put the electrode blade into working standby state, and use its surface composite functional coating to cut, coagulate or ablate tissue. Step S2: Mode switching selection. Depending on the needs during the operation, rotate the collar to select the instrument working mode to enter the clean mode or the smoke removal mode. Step S3: Blade head cleaning operation. In cleaning mode, when the blade head needs to be cleaned, pull back and then release the drive block.

Thus, while ensuring efficient and continuous cutting, the tissue interface temperature is controlled at a low level, reducing carbonization and reducing the thermal damage bandwidth. (2) In this invention, a mechanical cleaning system including an external airbag, an internal airbag and a telescopic mechanism is used. It can spray high-speed airflow and cleaning fluid alternately onto the blade head through a simple reciprocating pulling operation, physically peel off the attached material, realize the instant and active cleaning of the blade head during the operation, greatly enhance the anti-adhesion effect, and assist in local cooling. (3) In this invention, the rotatable end plate and collar design allows for easy switching between the instrument's cleaning mode and smoke removal mode by rotation. In smoke removal mode, the external airbag can actively draw in and filter smoke from the surgical area, effectively improving the clarity of the surgical field, protecting the health of medical staff, and realizing the multi-functional integration of a single instrument.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-9 As shown, a surgical low-temperature anti-adhesion radiofrequency plasma electrode includes a housing 1, a control component 2, an electrode blade 3, an end cap 5, and a power cord 8. The electrode also includes: Telescopic mechanism 4 includes a fixed plate 41, a sleeve 42, a movable plate 44, and an end plate 45. The fixed plate 41 has a threaded sleeve 411 on one side, which is threaded to the end 5. The sleeve 42 is fixed on the other side of the fixed plate 41 and is sleeved around the electrode knife 3. The movable plate 44 is slidably installed outside the sleeve 42. Several elastic elements 43 are connected between the movable plate 44 and the fixed plate 41. The end plate 45 is rotatably installed around the sleeve 42. Several connecting rods 47 are provided on one side of the movable plate 44. The other end of the connecting rods 47 passes through the fixed plate 41 and is provided with a connecting ring 48. A driving block 49 is provided on one side of the connecting ring 48. An external airbag 6 is installed between the movable plate 44 and the end plate 45. The external airbag 6 has several air inlets 61 and several air jets 62 at the end away from the fixed plate 41. The air inlets 61 and air jets 62 are distributed at intervals. Several exhaust holes 63 are opened on the outside of the external airbag 6. A filter plate 64 is provided inside the external airbag 6. An inner airbag 7 is installed between the movable plate 44 and the end plate 45. The inner airbag 7 is located inside the outer airbag 6. Both the outer airbag 6 and the inner airbag 7 are annular. Several liquid spray holes 71 are opened at the end of the inner airbag 7 away from the fixed plate 41. The inner airbag 7 is filled with cleaning fluid.

[0021] The control component 2 includes a PCB board 21, a switch board 22, and a conductive sleeve 23. The electrode blade 3 includes an electrode body 31, a blade head 32, and an insulating sleeve 33. The PCB board 21 is installed inside the housing 1, the switch board 22 is installed on the PCB board 21, the conductive sleeve 23 is connected to the PCB board 21, the electrode body 31 is fitted inside the conductive sleeve 23, one end of the electrode body 31 is provided with a blade head 32, the electrode body 31 is covered with an insulating sleeve 33, and the insulating sleeve 33 is in contact with the inner wall of the sleeve 42.

[0022] The blade 32 is coated with a protective layer.

[0023] In one embodiment, the cleaning fluid stored in the inner air bladder 7 may be physiological saline; the protective layer sprayed on the outside of the blade 32 includes a high-frequency energy selective conductive layer, a flexible ceramic insulating and heat-insulating layer, and a tissue contact layer with low surface energy and high dielectric stability.

[0024] In practical applications, the high-frequency energy selective conductive layer, the flexible ceramic insulating and heat-insulating layer, and the low surface energy anti-sticking layer are sequentially disposed on the outside of the cutter head 32 from the inside out, and each functional layer forms an electrical-thermal-surface energy gradient distribution in the thickness direction; wherein: The high-frequency energy selective conductive layer is made of carbon nanotubes, with CNT / metal nanowires as the main material. This is a conductive layer with nonlinear conductivity under high-frequency alternating electric fields. It has the characteristics of high DC resistance and reduced equivalent impedance at high frequencies (300–500kHz), which can avoid low-frequency leakage and ensure that high-frequency energy is concentrated at the cutting edge of the blade 32. Flexible ceramic insulation is a ceramic-polymer composite insulation layer that combines flexibility, thermal shock resistance, and electrical insulation properties. The materials can be alumina, zirconium oxide, boron nitride, organosilicon, polyimide, and sol-gel, etc. Its thermal conductivity is ≤1.5W / m·K and dielectric strength is ≥15kV / mm. This can suppress the diffusion of heat to non-cutting areas in the local area of ​​the cutting head, thereby reducing the depth of thermal damage. The tissue contact layer with low surface energy and high dielectric stability can be a PTFE / fluoropolymer anti-adhesion layer with a surface free energy ≤20mN / m and a contact angle ≥110°. It does not experience dielectric loss and temperature rise in a high-frequency electric field, thereby inhibiting protein and blood carbonization adhesion and reducing eschar formation. By separating the high-frequency energy path and the heat diffusion path, the energy required for tissue cutting is concentrated rather than the overall temperature rise. In this way, the energy is concentrated at the tissue-blade interface, rather than the temperature rise of the entire blade body, thereby achieving low thermal damage cutting, preventing tissue adhesion, and improving energy utilization efficiency. This results in effects such as reduced cutting temperature, significantly reduced adhesion, and reduced thermal damage depth.

[0025] During the surgery, even with a high-frequency energy selective conductive layer, a flexible ceramic insulating and heat-insulating layer, and a low surface energy-high dielectric stability tissue contact layer on the blade tip 32, some small tissues and blood will still "adhere" to the blade tip 32 due to high-frequency vibration during cutting. This adhesion is not true adhesion, but rather small tissues and blood adhering to the blade tip 32 due to high-frequency vibration. At this time, the doctor can press the drive block 49 and pull the fixing plate 41 backward to compress the elastic element 43, thereby causing the inner airbag 7 and the outer airbag 6 to... When stretched, the inner airbag 7 draws in air through the air inlet 61, and then the drive block 49 is released. Under the rebound action of the elastic element 43, the movable plate 44 squeezes the inner airbag 7 and the outer airbag 6. The air in the inner airbag 7 is ejected at high speed through the jet hole 62, and the cleaning fluid in the outer airbag 6 is ejected at high speed through the liquid spray hole 71. The ejected high-pressure air and high-speed cleaning fluid will directly act on the cutter head 32, thereby cleaning away the attached fine tissue and blood, thus improving the anti-adhesion effect. At the same time, it also cools down the cutting position and reduces thermal damage.

[0026] Furthermore, the end plate 45 is provided with several through holes 454 and several through holes 455. The number of through holes 454 is the same as the number of air inlets 61 and air jets 62, and the number of through holes 455 is the same as the number of liquid spray holes 71. The through holes 454, through holes 455, air inlets 61, air jets 62 and liquid spray holes 71 are arranged in a circular array. The outer sides of the air jets 62 and liquid spray holes 71 are respectively elastically rotatably mounted with a second blocking plate 621 and a fourth blocking plate 711. The inner side of the air inlet 61 is elastically rotatably mounted with a first blocking plate 611. When the second through hole 455 coincides with the liquid spray hole 71, the first through hole 454 coincides with the air inlet 61 and the air jet 62. When the liquid spray hole 71 is blocked by the end plate 45, the first through hole 454 coincides with the air inlet 61, and the air jet 62 is blocked by the end plate 45.

[0027] A collar 46 is rotatably installed around the movable plate 44. The collar 46 is located around the outer airbag 6. Several through holes 462 are opened around the collar 46. The number of through holes 462 is the same as the number of exhaust holes 63. A blocking plate 631 is elastically rotatably installed on the outside of the exhaust hole 63. When the liquid injection hole 71 is blocked by the end plate 45, the through holes 462 coincide with the exhaust hole 63.

[0028] An annular groove 1 452 and an annular groove 2 453 are respectively opened on the inner side of the end plate 45. The second blocking plate 621 is located in the first rotating groove 452, and the thickness of the second blocking plate 621 is equal to the thickness of the first rotating groove 452. The fourth blocking plate 711 is located in the second rotating groove 453, and the thickness of the fourth blocking plate 711 is equal to the thickness of the second rotating groove 453. An annular groove 3 461 is opened on the inner side of the collar 46. The third blocking plate 631 is located in the third rotating groove 461, and the rear end of the third blocking plate 631 is equal to the thickness of the third rotating groove 461.

[0029] The end plate 45 is provided with several guide strips 451 around its periphery, and the collar 46 is provided with several guide sleeves 463 around its periphery, with the guide strips 451 passing through the guide sleeves 463.

[0030] In one embodiment, the rotating parts of the first block 611, the second block 621, the third block 631, and the fourth block 711 can all be equipped with torsion springs.

[0031] In practical application, when it is necessary to clean small tissues and blood, the collar 46 is rotated to make the end plate 45 rotate synchronously, so that the first through hole 454 rotates to the air inlet 61 and the jet outlet 62, and the second through hole 455 rotates to the liquid spraying outlet 71. Then, the movable plate 44 is pulled backward by the drive block 49, the connecting ring 48 and several connecting rods 47, so that the outer airbag 6 and the inner airbag 7 are stretched, and the elastic element 43 is compressed, and the first blocking plate 611 flips inward into the outer airbag 6. Rotate to allow external air to enter the outer airbag 6, then release the drive block 49. Both the outer airbag 6 and the inner airbag 7 are compressed. The air in the outer airbag 6 squeezes the second blocking plate 621, causing the second blocking plate 621 to flip outward, thereby causing the air to be ejected at high speed from the jet hole 62. At the same time, the cleaning fluid pushes the fourth blocking plate 711 to flip, and the cleaning fluid is ejected at high speed from the spray hole 71. The ejected high-pressure air and high-speed cleaning fluid will directly act on the blade head 32, thereby cleaning away the attached fine tissue and blood. When it is necessary to clean up the smoke generated during cutting, rotate the collar 46 so that the through hole 454 rotates to the air inlet 61, blocking the jet hole 62 and the liquid spray hole 71 with the end plate 45. At the same time, the through hole 462 coincides with the exhaust hole 63. Then, the movable plate 44 is pulled back by the drive block 49 to stretch the outer air bag 6. The external smoke will enter the outer air bag 6 through the air inlet 61. The smoke is filtered by the filter plate 64. After releasing the drive block 49, the outer air bag 6 is compressed, and the filtered gas is discharged from the exhaust hole 63, thereby achieving the effect of cleaning up the smoke. At the same time, the moving speed of the drive block 49 can be manually controlled to adjust the rate of smoke extraction.

[0032] A method for using a surgical low-temperature anti-adhesion radiofrequency plasma electrode, the method being applied to the surgical low-temperature anti-adhesion radiofrequency plasma electrode as described above, the method comprising the following steps: Step S1: Instrument preparation and startup. Connect the power cord 8 and start the radio frequency energy generator through the control component 2 to put the blade head 32 of the electrode knife 3 into the working standby state, and use its surface composite functional coating to cut, coagulate or ablate tissue. Step S2: Mode switching selection. Depending on the needs during the operation, rotate the collar 46 to select the instrument working mode to enter the cleaning mode or the smoke removal mode. Step S3: Blade head cleaning operation. In cleaning mode, when the blade head 32 needs to be cleaned, pull back and then release the drive block 49. This operation causes the outer airbag 6 and the inner airbag 7 to expand and then compress through the telescopic mechanism 4, thereby spraying high-speed airflow and cleaning fluid into the blade head 32 area to remove the attached substances and cool the local area. Step S4: Smoke removal operation. In smoke removal mode, when surgical smoke needs to be removed, pull back and then release the drive block 49. This operation causes the external airbag 6 to periodically expand and compress, thereby actively sucking in the smoke from the surgical area. After being filtered by the filter plate 64, clean gas is discharged.

The insulating sleeve (33) is in contact with the inner wall of the sleeve (42).

7. The surgical low-temperature anti-adhesion radiofrequency plasma electrode according to claim 6, characterized in that, The cutter head (32) is coated with a protective layer.

8. A method of using a surgical low-temperature anti-adhesion radiofrequency plasma electrode, characterized in that, The method is applied to the surgical low-temperature anti-adhesion radiofrequency plasma electrode as described in any one of claims 1-7 above, and the method includes the following steps: Step S1: Instrument preparation and startup, connect the power cord (8), start the radio frequency energy generator through the control component (2), so that the blade (32) of the electrode knife (3) enters the working standby state, and uses the composite functional coating on its surface to cut, coagulate or ablate tissue; Step S2: Mode switching selection. Depending on the needs during the operation, rotate the collar (46) to select the instrument working mode to enter the clean mode or the smoke removal mode. Step S3: Blade head cleaning operation. In cleaning mode, when the blade head (32) needs to be cleaned, pull back and then release the drive block (49). This operation causes the outer airbag (6) and inner airbag (7) to expand and then compress through the telescopic mechanism (4), thereby spraying high-speed airflow and cleaning fluid into the blade head (32) area to remove the attached substances and cool the local area. Step S4: Smoke removal operation. In smoke removal mode, when surgical smoke needs to be removed, pull back and then release the drive block (49). This operation causes the external airbag (6) to periodically expand and compress, thereby actively drawing in the smoke from the surgical area and discharging clean gas after filtration by the filter plate (64).
