Description

Portable Safety Cervical Therapy Apparatus

technical field

The invention relates to a gynecological medical instrument, in particular to a portable safe cervical treatment instrument with a PTC thermistor as an electric heating element and a polytetrafluoroethylene heat-insulating sleeve.

Background technique

Chronic cervicitis has a higher incidence rate in sexually active women. The main pathological types are cervical erosion, cervical hypertrophy, cervical polyps, and cervical gland cysts, which not only affect female reproductive health, but also affect marriage life and childbearing. Some patients It can also cause cervical cancer. Chronic cervicitis is mainly based on local treatment, and physical therapy, drug therapy and surgical treatment can be used, and physical therapy is the most commonly used.

The principle of physical therapy is to destroy the single-layer columnar epithelium on the cervical erosion surface by various physical methods, make it necrotic and fall off, and then be covered by the new stratified squamous epithelium, the cervix becomes smooth, and the erosion is cured. Commonly used methods are cervical electric ironing, laser therapy, cryotherapy, infrared coagulation therapy, microwave therapy, and high-frequency radio-knife therapy.

The advantages of cervical electric ironing method are: first, it not only has a good therapeutic effect on cervical erosion epidermis, but also has good therapeutic effect on cervical shape, cervical gland cyst and cervical polyp; second, gynecological electric iron is cheap, easy to carry and Easy to use, especially suitable for use in rural grassroots. But the gynecological electric iron commonly used at present has the following disadvantages in terms of operational safety: first, due to the use of iron-chromium-aluminum alloy or nickel-chromium alloy heating wire as the heating element, the temperature of the electric iron head cannot be controlled, and it is easy to produce excessive temperature and cause damage to the electric iron. The normal tissue of the treatment site for deep burns; second, because the metal sleeve other than the electric iron head is not covered with heat-insulating material, it is easy to accidentally burn the vulva and vaginal wall tissues during the operation; third, because the electric iron head has a single design shape, it is not easy to Perform various operations such as cervical gland cyst treatment, cervical erosion planar treatment, and external cervical os repair modeling.

However, other instruments are expensive, require high surgical conditions and operating techniques, and are difficult to popularize at the grassroots level in rural areas. Moreover, the above-mentioned instruments have a good effect on the erosive epidermis of the cervix, but are less effective on the shape of the cervix and the treatment of cervical gland cysts and cervical polyps.

If the existing technological achievements in material science can be adopted, more advanced materials can be used, and the operation safety of gynecological electric irons can be increased, and the advantages of cervical electric ironing will be fully brought into play.

PTC is the abbreviation of Positive Temperature Coefficient, which means a positive temperature coefficient, and generally refers to semiconductor materials or components with a large positive temperature coefficient. Usually the PTC we refer to refers to the positive temperature coefficient thermistor, referred to as the PTC thermistor. PTC thermistor is a typical temperature-sensitive semiconductor resistor. When it exceeds a certain temperature (Curie temperature), its resistance value increases stepwise with the increase of temperature. Using PTC thermistor as the electric heating element has the advantages of rapid temperature rise, constant temperature, energy saving and long service life. PTC thermistors have been widely used in many fields such as electric iron heaters, but there are no patents for cervical therapeutic instruments and gynecological electric irons.

Polytetrafluoroethylene (PTFE), commonly known as "Plastic King", Chinese trade name "Teflon", "Teflon", "Teflon", "Teflon" and so on. It is a polymer compound polymerized by tetrafluoroethylene. It has excellent chemical stability, corrosion resistance, high lubrication and non-stickiness, electrical insulation, low thermal conductivity, and can be used at temperatures from +250°C to -180°C. Under long-term work, it is widely used as high and low temperature resistant, corrosion resistant materials, insulating materials, anti-stick coatings, etc. in electronics, electrical, chemical, instrument, meter, medical, food and other industries. At present, there is no patent on polytetrafluoroethylene as a thermal insulation material for cervical therapeutic instruments and gynecological electric irons.

Contents of the invention

The portable safe cervical treatment instrument of the present invention aims at the limitations of the gynecological electric irons currently used clinically in terms of operational safety performance and surgical application, and provides a safe operation, convenient portability, low price, and is suitable for use by rural and community grassroots medical units. cervical treatment device.

In order to achieve the above object, the present invention adopts the following technical solutions:

The portable safe cervical therapeutic instrument includes electric iron head, electric heating element, heat insulation cover, switch, handle, wire, plug and other parts. The PTC electric heating element is placed in the cavity at the tail of the electric iron head, the tail of the electric iron head is inserted into the polytetrafluoroethylene heat insulation sleeve, the polytetrafluoroethylene heat insulation sleeve is inserted into the handle, there is a switch on the handle, and one end of the wire is connected to the electric heating element. The other end goes through the middle of the handle and connects to the plug.

Because the PTC thermistor is used as the electric heating element, the temperature of the electric iron head can be controlled, and the normal tissue of the treated part will not be deeply burned. Due to the use of polytetrafluoroethylene heat insulation sleeve, it will not accidentally burn the vulva and vaginal wall tissue. The above-mentioned technology ensures the operational safety of the cervical therapeutic apparatus.

The head of the electric iron head can be designed into different shapes such as small spherical shape, flat shape, bullet shape, etc., which can conveniently perform operations such as the treatment of cervical gland cyst, the treatment of cervical erosion plane, the treatment and modeling of the external os of the cervix.
