Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a single-pole low-temperature plasma surgical electrode with a flow control and a dripping function. Background Art

[0002] Plasma surgical electrodes are used for cutting tissue and electrocoagulation to stop bleeding. Existing plasma surgical electrodes have the following defects during surgery: First, during tissue cutting and coagulation, the electrode surface will generate instantaneous high temperature and heat, which will burn the surgical tissue site; second, during the operation, denatured tissue is more likely to adhere to the surface of the electrode and the tip of the blade. At the same time, the denatured tissue adhered to the tip of the electrode blade will hinder the diffusion of the plasma generated at the tip, and have a negative impact on the cutting and coagulation effects during the operation. Therefore, a single-pole low-temperature plasma surgical electrode with a drip control function is urgently needed to solve the above problems. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A flow-controlled single-pole low-temperature plasma surgical electrode with a dripping function comprises a plastic handle 1, the front end of the plastic handle 1 is connected to an insulating sleeve 2, the rear end of the plastic handle 1 is connected to a tail sleeve 3, an electrode blade 10 is installed at the front end of the insulating sleeve 2, a water hole 12 is opened at the tip of the electrode blade 10, a metal long rod 11 is installed in the inner cavity of the tail sleeve 3, the plastic handle 1 and the insulating sleeve 2, the front end of the metal long rod 11 is connected to the water hole 12, the rear end of the metal long rod 11 is connected to a drip pipe body 4, the rear end of the drip pipe body 4 is connected to a physiological saline supply device 6, a valve switch device 5 is installed on the drip pipe body 4, and the upper and lower surfaces of the electrode blade 10 are attached with an insulating coating, which can be a siloxane film.

[0020] The diameter of the water hole 12 is 1 mm.

[0021] The physiological saline supply device 6 includes a physiological saline bottle and a vacuum pressure source 7. The vacuum pressure source 7 can be a common vacuum pump on the market.

[0022] The two ends of the drip tube body 4 are respectively a drip tube A end 8 and a drip tube B end 9. The drip tube A end 8 is connected to a long metal rod 11, and the drip tube B end 9 is connected to a bottle of physiological saline.

[0023] The valve switch device 5 is specifically a manual butterfly valve.

[0024] The drip pipe body 4 is specifically a plastic transparent hose.

[0025] The upper and lower surfaces of the electrode blade 10 are sprayed with an insulating coating, and the blade tips around the electrode blade 10 are sharpened to ensure that the electrode blade 10 can transmit the high-frequency and high-voltage current output by the high-frequency generator. The insulating coating can effectively isolate the high temperature and heat generated during the operation, so that the peripheral position of the electrode is in a low-temperature environment, reducing the risk of electric heat burning and scalding of the patient's surgical site.

[0026] A 1 mm water hole 12 is processed at the tip of the electrode blade 10, and the water hole 12 is connected to the metal long rod 11 inside the insulating sleeve 2. At the same time, the drip pipe A end 8 of the drip pipe body 4 equipped with a valve switch device 5 is connected to the tail end of the metal long rod 11, and the drip pipe B end 9 of the drip pipe body 4 is connected to the saline supply device 6. The valve switch device 5 can control the flow rate of the saline during the operation by turning the valve to open and close.

[0027] The process of physiological saline outflow is as follows: the vacuum pressure source 7 of the physiological saline supply device 6 provides power, the valve switch device 5 is opened, and the physiological saline flows to the drip pipe B end 9 through the physiological saline supply device 6, and then flows to the drip pipe A end 8 through the drip pipe body 4, and then flows to the water hole 12 through the metal long rod 11, and flows to the patient's surgical site through the water hole 12. Therefore, the outflowing physiological saline can further absorb part of the high temperature and heat generated by the electrode blade 10 during the operation, and can increase the hydrophobicity of the insulating coating on the surface of the electrode blade 10, so as to achieve the purpose of physical cooling and preventing the adhesion of denatured tissue and electrode. It plays a role in improving the efficiency of surgery and reducing the surgical pain of patients suffering from electric heat burning and scalding.
