Abstract
The present invention relates to a silica gel treating catheter for microwave thermal therapeutic apparatus. A tube wall of a microwave transmitting antenna tube cavity of the present invention is provided with a silica gel sleeve. The rear part of a center hole of the silica gel sleeve is an inflated part, the front part of the center hole is a confined part, the diameter of the inflated part is larger than that of the microwave transmitting antenna, and the diameter of the confined part is less than that of the microwave transmitting antenna. When the silica gel sleeve is formed, a first forming rod and a second forming rod are respectively stretched into both ends of the microwave transmitting antenna tube cavity until the head parts contact each other. The head part of the first forming rod, the second forming rod and the tube wall of the microwave transmitting antenna tube cavity are enclosed into a forming cavity of the silica gel sleeve. The position of the forming cavity of the silica gel sleeve is heated to melt silica gel raw materials coated on the head part of the first forming rod to be filled in the forming cavity of the silica gel sleeve and to be bonded with the tube wall of the microwave transmitting antenna tube cavity. The present invention has the advantage that cooling water can not seep in the position of the microwave transmitting antenna tube cavity at a microwave emission point.
Description
(1) technical field
The present invention relates to a kind of silica gel therapeutic catheter for microwave thermo-therapeutic apparatus and manufacture method thereof.
(2) background technology
Diseases of urinary system such as prostatic diseases and some common gynecological diseases such as vaginitis, urethritis, cervicitis adopt medication effect undesirable, adopt the routine operation wound big, cause very big misery for patient's body and mind.In recent years, adopt Minimally Invasive Surgery to treat to this class disease, operation wound is little more, and it is fast that patient recovers.Especially conduit cooperates microwave heat therapeutic instrument to carry out the operation misery that microwave heat therapeutic can further alleviate patient, need not anesthesia, can finish in outpatient service, has easy, safe characteristics.
The body of silica gel therapeutic catheter for microwave thermo-therapeutic apparatus has microwave transmitting antenna tube chamber, backwater tube chamber and thermometric tube chamber, in order to insert the microwave transmitting antenna, the diameter of microwave transmitting antenna tube chamber is larger than the diameter of microwave transmitting antenna usually, point for measuring temperature is near the launch point of microwave transmitting antenna, microwave transmitting antenna tube chamber is communicated with the front end of backwater tube chamber, thereby makes microwave transmitting antenna tube chamber and backwater tube chamber constitute cooling water circulation chamber.During use conduit is inserted in the patient body, behind the arrival diseased region, microwave transmission antennas transmit point launched microwave heats to treat diseased region.In operation process, the cooling water circulation intracavity of being made up of microwave transmitting antenna tube chamber and backwater tube chamber has continuous mobile cooling water, is not subjected to thermal burn to guarantee the normal physiological position.
The microwave transmitting antenna tube chamber of present most of silica gel therapeutic catheter for microwave thermo-therapeutic apparatus is positioned at point for measuring temperature the place ahead with the backwater tube chamber place of connection, basically foremost near whole conduit, cooling water is also basically at the whole axial range internal recycle of conduit like this, and new type of microwave thermal therapeutic apparatus treating silica gel duct, its microwave transmitting antenna tube chamber and the place of connection of backwater tube chamber front end are positioned at the rear of point for measuring temperature, this new type of microwave thermal therapeutic apparatus treating silica gel duct is compared with old technology has following advantage: 1. because point for measuring temperature and launch point are not subjected to the temperature fluctuation of cooling water, the influence of factors such as cooling water recirculation system fault, the measured temperature of thermometric line is stable, can not produce fluctuation, help microwave heat therapeutic instrument the treatment temperature controlling.2. under identical condition, the temperature difference between the measurement temperature of thermometric line of the present invention and the actual therapeutic temperature of diseased region is far smaller than existing this temperature difference in the old technology, and microwave heat therapeutic instrument is more accurate to the treatment temperature computation of diseased region.3. the launch point of microwave is not in the cooling range of cooling water, and for the heating of diseased region, it is very fast to make it to reach the temperature required process of treatment, has reduced treatment time, has alleviated patient's misery.
But because microwave transmitting antenna tube chamber and the place of connection of backwater tube chamber are positioned at the rear of point for measuring temperature, produce a new problem thus again: need prevent that cooling water from infiltrating the microwave transmitting antenna tube chamber position at microwave launch point place, if cooling water infilters the microwave transmitting antenna tube chamber position at microwave launch point place continuously, might cause the range of DO of cooling water to expand microwave launch point and point for measuring temperature in-scope again to, microwave transmitting antenna tube chamber is sayed with regard to meaningless with this architecture advances of rear that the backwater tube chamber place of connection is positioned at point for measuring temperature so.Yet this problem is not also effectively solved at present.
(3) summary of the invention
In the prior art, microwave transmitting antenna tube chamber is positioned at the novel microwave thermal therapeutic apparatus treating silica gel duct at point for measuring temperature rear when moving with the place of connection of backwater tube chamber front end, the microwave transmitting antenna tube chamber position phenomenon that cooling water infiltrates microwave launch point place is more serious, in order to overcome this shortcoming, the invention provides the silica gel therapeutic catheter for microwave thermo-therapeutic apparatus that a kind of cooling water can not infiltrate the microwave transmitting antenna tube chamber position at microwave launch point place, its microwave transmitting antenna tube chamber also is positioned at the point for measuring temperature rear with the place of connection of backwater tube chamber front end, and provides the manufacture method of this silica gel therapeutic catheter for microwave thermo-therapeutic apparatus.
