1998 65438+February-1June 1999 We used DNR300 numerical control thermocoagulation system provided by Hunan Aoshi Electric Company to treat 2 15 cases of condyloma acuminatum, 59 cases of common warts, 65 cases of external hemorrhoids, 80 cases of benign tumors and 565438+ of cervical erosion. At the same time, 150 cases of condyloma acuminatum, 87 cases of hemorrhoids, 56 cases of verruca vulgaris, 62 cases of benign tumors, 57 cases of cervical erosion and 93 cases of cervical polyps were compared by high frequency electrocautery and microwave therapy, and the clinical comparative study was made. The results are reported as follows:

1 materials and methods: the patients diagnosed with the above diseases were randomly divided into treatment group and control group. See table 2 for gender classification, age 15-55, and the natural distribution conforms to the statistical standard. Several groups of cases meet the diagnostic criteria of professional disciplines.

Indications and contraindications

2. 1 indications: it is applicable to all diseases that meet the diagnosis of gynecological and dermatological diseases, such as irreversible inflammation, reactive hyperplasia and hypertrophy of local tissues, and benign tumors diagnosed by biopsy.

2.2 Contraindications: Generally, it is not carried out during the acute attack of inflammation, but should be treated after 2-3 weeks of inflammation. Systemic diseases, such as active tuberculosis, rheumatic heart disease, nephritis, etc. , should be suspended when the condition is unstable.

Three treatment methods

3. 1 equipment preparation: use the numerical control thermal coagulation treatment system provided by Hunan aoshi electric company, and the software digital energy working code is MRC code. The peak voltage of digital module is ≤AC 10V, and the combined digital energy power is 180W. The transmitter is made of platinum, and the common specifications and models are 3mm × 3mm × 3mm.

3.2 operation method: adjust the computer automatic temperature control program at 30℃ ~ 300℃; The patient was taken to the lying position and disinfected regularly for 5 minutes around. (Use 1% tetracaine to anesthetize the gynecological mucosal tissue area for 3 times, with an interval of 5 minutes. For other diseases, 5ml of 0.5%~ 1% lidocaine hydrochloride solution was extracted with 10ml syringe, and routine local infiltration anesthesia was performed. After 5min minutes, the transmitter was attached to the surface of the diseased tissue and treated at 1-3 acupoints for 2-6 seconds. After the diseased tissue solidifies into white or yellow, the treatment is over. Observation 10 minutes, leaving the treatment room, no adverse reactions. The treatment time depends on the patient's cooperation.

3.3 postoperative treatment: (1) local application of MEBO or 0.25% erythromycin eye ointment (mostly used in mucosal tissues) to prevent tissue edema caused by local heat after treatment. (2) Routine intramuscular injection or oral antibiotics to prevent infection. (3) review after 7 days to 3 months. It usually takes only 1 time to cure, and the postoperative follow-up observation is 1 year.

Evaluation criteria of curative effect: the recovery criteria are non-recurrence of inflammation and normal atrophy of tumor or hemorrhoid nucleus. Remarkable effect: the lesion area was obviously improved;

Invalid: Symptoms and signs have not changed.

6 discussion

6. 1 physical therapy methods in dermatology and gynecology According to the retrieval data, there are many methods, such as laser, cryotherapy, infrared ray, ordinary electrocoagulation, high-frequency electrocautery, microwave, etc. At present, microwave and high-frequency electrocautery are popular, but these conventional treatments all adopt open-loop control circuits (simply adjusting treatment time, treatment voltage and treatment current), and there is no thermoelectric signal feedback circuit in local tissues. It is easily influenced by local tissue size, moisture, sputum and blood, and the heat is not easy to control, and the damage uniformity to surrounding normal tissues and nerves is poor. Either the injury is large, or the coagulation energy is not enough, which can not achieve the best therapeutic effect, and it is easy to bring complications such as secondary diseases and scar adhesion. According to the animal gelatin test and the measurement of the temperature in the tissue of the treatment area, the pathological examination proves that the computer numerical control thermocoagulation therapy can feedback the temperature electric signal in real time under the automatic control of the computer, and the computer makes correct instructions to ensure that the thermocoagulation temperature is controlled at 30℃~300℃. When the temperature in the tissue is too low, the computer automatically heats it and records the increased energy; On the contrary, the computer stops heating. This can not only ensure less damage to the surrounding normal tissues, but also achieve the purpose of rapid treatment.

6.2 The principle of using modern computer numerical control thermal coagulation technology is that the digital thermal energy code will generate corresponding energy when it passes through a special transmitter, which can make the contacted tissue produce biological thermal effect. The thermal energy control of this instrument is different from that of conventional instruments. It is controlled by electrical signals fed back by thermal sensors in local tissues. When the local temperature rises to 30℃~300℃, the computer of the therapeutic instrument receives the numerical control signal and executes the command to maintain the energy. At the same time, the protein of swollen or diseased tissue is coagulated and denatured, and the denatured tissue naturally falls off due to inactivation, and finally the swollen or diseased tissue contracts to normal [4].

6.3 For some patients, we use the camera system randomly configured by this system to store the color pictures of the focus area, which is of great help to the later comparative treatment effect and clinical academic discussion. In the treatment of gynecological cervical erosion and polyp with narrow field of vision, automatic energy control program is adopted, which effectively improves the safety of treatment. Through INTERTEN network, we obtained the picture transmission and video conversation with the science and technology department of Aoshi Electric Company during the treatment, which enabled us to remotely command the unclear parts of the system when operating the instrument. For example, in the process of treatment, the system program has an error prompt, which we can't solve by ourselves. Through the remote command of their technical department, we quickly found a way to eliminate the fault and the operation was carried out normally. The instrument has many functions, which truly embodies the attributes of modern multimedia technology. Put the learning CD into the computer CD, and you can play the demonstration operation process by yourself. It is a novel, practical and scientific product to achieve the purpose of computer teaching. This machine is equipped with a portable industrial control computer suitable for medical specialty, which is suitable for Windows.

6.4 It is suggested to train a new generation of professionals who combine medical technology with computer technology as soon as possible to meet the needs of clinical operation and further scientific research. Further improve the image transmission rate on the Internet.

High frequency: the control group was electrocautery with high frequency. Table 1 shows that computer numerical control thermocoagulation is used in dermatology and gynecological diseases, with the above effect and low recurrence rate. [3] It has the advantage of easy bleeding, as can be seen from Table 2. After all, it is significantly lower than that of the control group (P & lt0.0 1). It shows that the response of computer numerical control postoperative treatment to this disease is better than that of microwave treatment for high frequency electrocautery. 6. On the basis of discussing 6. 1 dermatology and gynecology physical therapy methods, it shows that there are many methods to retrieve information, such as laser, freezing, infrared ray, general coagulation, high-frequency electrocautery, microwave, microwave and high-frequency electrocautery therapy are more popular. However, these conventional open-loop control circuits (used for simple treatment adjustment, current treatment voltage and treatment size) have no thermoelectric signal feedback circuit for local tissues, so local tissues are easily controlled by size, humidity, phlegm, blood and heat. The damage and uniformity of nerve to surrounding normal tissues are poor, and it can't be damaged. The energy of coagulation is not enough, and the treatment effect is not good, and secondary diseases and scars are easy to bring complications. According to the animal experiment and treatment, the pathological examination of gelatin temperature measurement confirmed that the computer numerical control coagulation treatment was carried out under the control of computer. The real-time temperature feedback signal from the computer makes the solidification direction correct and ensures that the temperature is controlled at 30 ℃- 30℃. When the tissue temperature is too low, the computer automatically heats it and supplements the energy to the record; Instead, the computer stopped supplying heat. This ensures less damage to the surrounding normal tissues and achieves the purpose of rapid treatment. 6.2 Using modern computer technology, the principle is that when the numerical control solidification heat passes through a special code number, they will have a bioenergy organization with emission ability and will be exposed to thermal effect. Thermal control equipment and conventional machines, the latter feeding back control signals from thermal sensors of local institutions. When the local temperature rises to 30c-30c, the numerical control instrument sends out a signal, and the computer accepts the command to maintain the energy. At the same time, swelling or pathological changes coagulate denatured proteins, and due to the inactivation of naturally mutated tissues, the tissues decrease, and finally the tissues expand or shrink into normal diseases [4]. 6.3 For some patients, we use randomly assigned camera system to take color photos of the storage area, and the comparison of academic and clinical curative effects is of great help to the later discussion. In the treatment of cervical erosion and Y-polyp stenosis in gynecological surgery, energy control program is used to effectively improve the safety of treatment. INTERTEN obtains treatment photos and transmits video conversations around the world through the Internet, the Ministry of Science and Technology and Austrian companies. We have to operate the equipment, and the system is not clear where to conduct remote command. For example, once the system prompts an error during the treatment, we cannot solve it. Through their remote command technology, we can quickly find a way to troubleshoot and resume normal operation. The machines used by these machines truly reflect the essence of modern multimedia technology. CD-ROM into computer CD-ROM learning, self-broadcast demonstration surgery; To achieve the purpose of computer teaching, a novelty lies in the practicality of new scientific products. IPC medical professional mobile computer windows < lt/a >; Countries such as 98 phtoshop5.0 micosoft word and apoA mtime5.0 have given prestigious pre-installed software, so it will be very helpful to improve the computer level of medical staff in their spare time. 6.4 Cultivate a new generation of professionals who combine medical technology with computer technology as widely as possible. Surgery and further clinical research to meet the needs; Further improve the online image transmission rate. Seven conclusions of this study show that computer numerical control thermocoagulation can treat dermatosis and gynecological diseases. The method is simple, rapid, safe and reliable, and can cure diseases without obvious side effects. This therapy has the advantages of light pain and no bleeding after operation, and has good clinical application value. It is convenient for hospitals to promote.
