[specific embodiment]
The following example is to further explanation of the present utility model and explanation, and this utility model is not constituted any limitation.
The micro-radio-frequency electrode treatment of utilization described in the utility model sphincter dilatation equipment is under the cooperation of endoscope, and flexible conduit directly acts on ill part by oral cavity, esophagus or urethra.This equipment uses the control type main frame of Specialty Design to produce the radio frequency electromagnetic of firm power, and the micro-radio frequency of this sine wave provides the temperature control radio-frequency (RF) energy by flexible conduit to human body sphincter position.Radio-frequency electrode and dispersive electrode constitute the closed-loop path.When radio-frequency current during through tissue, because of resistance loss is converted into heat energy, diseased region is heated up, the inside and outside water evaporates of cell, drying, pyknosis, so that aseptic necrosis, thereby reach therapeutic purposes.Radio-frequency (RF) therapy increases sphincter thickness by heat energy treatment back, the deactivation teleneuron, and the inactivation of vagus nerve receptor, collagen tissue is shunk, thereby increases sphincter thickness and pressure down, makes sphincter recover elasticity.
As shown in Figure 1, this equipment can be divided into two parts substantially, and a part is for directly stretching into the flexible conduit 10 of human body, and another part is that the radio-frequency electrode that is used to produce rf wave and analyze corresponding data takes place and control device 20.
As shown in Figure 2, radio-frequency electromagnetic wave generating device 13 produces radio frequency electromagnetic and directly acts on sufferer sphincter partly by radio-frequency electrode 26, constitutes the closed-loop path with the dispersive electrode that is connected on the information analysis collection and treatment device 12.Simultaneously the information collected according to temperature sensor 24 and impedance transducer 25 of information analysis collection and treatment device 12 is sent the order that generates electromagnetic waves or stop to radio-frequency electromagnetic wave generating device 13.When temperature that the sphincter surface is sensed in temperature sensor 24 is greater than or equal to 80 ℃ or the temperature in the sphincter layer when being greater than or equal to 50 ℃, such temperature causes sphincter easily and burns, send the too high signal of temperature to information analysis collection and treatment device 12, information analysis collection and treatment device 12 will send the signal that stops to produce radio frequency electromagnetic to radio-frequency electromagnetic wave generating device 13; Same when impedance transducer 25 be that information analysis collection and treatment device 12 sends the signal that stops to produce radio frequency electromagnetic according to the signal of impedance transducer 25 to radio-frequency electromagnetic wave generating device 13 less than 100 ohm or during greater than 1000 ohm according to the working impedance of the closed-loop path of sensing.When working impedance during less than 100 ohm, there is the probability of short circuit in expression, can produce too high temperature like this; When working impedance during greater than 1000 ohm, expression has reached therapeutic effect, proceeds to produce the problem of burning.
Timing means 11 can carry out setting in advance to treatment time (being the radio frequency electromagnetic generation time), when but the signal that is sent according to temperature sensor 24 and impedance transducer 25 when information analysis collection and treatment device 12 sent the signal that stops to generate electromagnetic waves, preestablishing of timing means 11 ceased to be in force automatically.
