Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a flushing and suction type low-temperature non-stick plasma surgical electrode. Background Art

[0002] Plasma surgical electrodes are mainly used for cutting tissue and electrocoagulation to stop bleeding. They are widely used in clinical practice and are becoming more and more widely used. They have the dual functions of cutting and coagulation. At present, existing plasma surgical electrodes are not only used in direct vision surgery, but also in laparoscopic and other endoscopic surgeries.

[0003] Although the existing plasma surgical electrodes (without internal suction catheters and no insulating coating on the electrode surface) can meet the functions of cutting tissue and electrocoagulation hemostasis during surgery, they have the following defects during surgical use: First, the denatured tissue is more likely to adhere to the surface of the electrode and the tip of the blade. The denatured tissue adhered to the surface of the electrode will hinder the doctor's vision during surgery, affect the doctor's subjective judgment during surgery, and increase the medical risk of surgical errors. At the same time, the denatured tissue adhered to the tip of the electrode blade will also hinder the diffusion of plasma generated at the tip, and have a negative impact on the cutting and coagulation effects during surgery; second, during tissue cutting and coagulation, the high-frequency high-voltage current output by the high-frequency generator will act on the electrode of the existing plasma surgical electrode, and the instantaneous high temperature and heat generated on the electrode surface will burn the surgical tissue site, which is easy to cause the patient's surgical site scald medical risk; third, during surgery, blood stains generated during tissue cutting or coagulation are easy to accumulate at the tissue slit position. As the operation time increases, more and more blood will accumulate in the tissue slits, which will also obstruct the doctor's field of vision during the operation, affect the doctor's subjective judgment during the operation, and increase the medical risk of surgical errors by the doctor.

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-3 , the utility model provides a technical solution:

[0022] A flushing and suction type low-temperature non-stick plasma surgical electrode comprises a plastic handle 1, a handle control switch 2 is installed on the side of the plastic handle 1, a blade seat 11 is installed at the front end of the plastic handle 1, and the rear end of the blade seat 11 is connected to the plastic handle 1 through an insulating sleeve, an electrode blade 10 is installed at the front end of the blade seat 11, and the front end of the electrode blade 10 is a blade tip 16, and the upper and lower surfaces of the electrode blade 10 are provided with insulating coatings 15, a discharge hole 12 is provided at the upper part of the front end of the blade seat 11, and a flushing hole 14 is provided at the lower part of the front end of the blade seat 11, and a tail sleeve 3 is provided at the rear end of the plastic handle 1, and the rear ends of the tail sleeve 3 are respectively connected to a flushing catheter 4 and a discharge catheter 9, the end of the flushing catheter 4 is connected to a physiological saline supply device 6, and the end of the discharge catheter 9 is connected to a vacuum pressure source D 7.

[0023] A tool head mounting groove 13 for mounting the electrode tool head 10 is formed at the front end of the tool head seat 11 .

[0024] The flushing conduit 4 is communicated with the flushing hole 14 , and the discharge conduit 9 is communicated with the discharge hole 12 .

[0025] A valve switch device A 5 is installed on the flushing conduit 4, and a valve switch device B 8 is installed on the discharge conduit 9.

[0026] The physiological saline supply device 6 includes a flushing liquid bottle and a vacuum pressure source C17.

[0027] The insulating coating 15 is specifically a siloxane film.

[0028] An insulating coating 15 is sprayed and attached to the upper and lower surfaces of the electrode blade 10, and at the same time, the blade tips 16 around the electrode blade 10 are sharpened to ensure that the sharpened electrode blade 10 can transmit the high-frequency and high-voltage current output by the high-frequency generator. The coating composition of the insulating coating 15 is mainly composed of raw materials that can form Si-O bonds as film-forming substances, and the formed Si-O bonds are used to construct a network cross-linked siloxane film, which can play a role in high temperature resistance and hydrophobic anti-adhesion. Therefore, the insulating coating 15 attached to the upper and lower surfaces of the electrode blade 10 can effectively isolate the instantaneous high temperature and heat generated during the operation, so that the peripheral position of the electrode blade 10 is in a low-temperature environment, thereby reducing the risk of electric heat burning and scalding of the patient's surgical site and tissue adhesion and scabbing on the outer surface of the electrode blade 10.

[0029] The flushing catheter 4 and the exhaust catheter 9 are sequentially assembled and distributed on both sides of the electrode blade 10, inside the insulating sleeve, inside the plastic handle, and finally extend out through the tail sleeve 3. The flushing catheter 4 is connected to the external saline supply device 6 through the valve switch device A 5. The specific steps of flushing are as follows: the vacuum pressure source C 17 in the saline supply device 6 is opened to provide flushing gas source pressure, and the vacuum pressure source D 7 is closed. The flushing gas source pressure causes the saline in the flushing liquid bottle to flow through the trachea to the flushing catheter 4, and the saline then flows through the flushing hole 14 to the tissue slit position of the surgical site of the patient, so as to achieve the purpose of flushing blood and denatured tissue. The specific steps of exhausting are as follows: the vacuum pressure source D 7 provides the exhaust gas source pressure, and then the valve switch device B 8 is opened. The exhaust gas source pressure sucks the waste liquid and denatured tissue into the exhaust catheter 9 through the exhaust hole 12, and then sucks them into the medical waste vacuum barrel through the trachea, so as to achieve the purpose of sucking and exhausting the waste liquid and denatured tissue. The vacuum pressure source C 17 and the vacuum pressure source D 7 Specifically, it is a common pressure pump on the market. The waste liquid and denatured tissue in the operation process can be flushed and discharged through the above process, which can improve the doctor's surgical field of view during the operation, improve the accuracy and efficiency of the operation, and reduce the patient's surgical pain.
