Abstract
The invention relates to a temperature-measuring focused ultrasound transducer for curing tumor and an improvement method thereof. In the transducer of the invention, a laser thermodetector is arranged on the side of the central B ultrasonic head of the focused ultrasound transducer and opposite to a curing are; when the focused ultrasound transducer transmits ultrasonic wave for curing, the laser thermodetector is turned on; and the circuit is turned off or on to ensure that the focused ultrasound transducer stops curing or transmits ultrasonic wave for curing according to the rise and fall of the measured temperature on skin surface above the curing region of a patient, and the B ultrasonic head is used to observe the tumor-curing effect of the focused ultrasound transducer. By using the laser temperature-measuring transducer, the effectiveness and safety of the focused ultrasound curing of tumor can be further increased, and the transducer is efficient, convenient, practical and economical.
Description
Technical field
The present invention relates to a kind of transducer of focused ultrasound therapy tumor and the improvement of method, the particularly a kind of transducer of thermometric focused ultrasound therapy tumor and the improvement of method.
Background technology
The transducer of the focused ultrasound therapy tumor in the innovation and creation does not at present have temperature measuring equipment, for preventing that skin and subcutaneous tissue from burning, the temperature measurement technology of patient's skin surface above the focused ultrasound therapy zone be with range estimation, hands is touched or thermometer is measured and the treatment process is implemented control; Efficient is not high, poor accuracy, and the guarantee of treatment safety is difficult for.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of transducer of thermometric focused ultrasound therapy tumor and the improvement of method are provided, and avoids skin and subcutaneous to burn, and makes the guarantee of treatment safety improve highly effective.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
Side in the focused transducer central B ultrasonic head is installed the laser temperature-measuring device of aiming at area for treatment; When focused transducer is opened the laser temperature-measuring device when launching ultrasonic therapy; Measuring temperature when the laser temperature-measuring device from the skin surface of patient's area for treatment top heats up and surpasses the treatment exposed body surface initial temperature more than 5 ℃ when (as reaching more than 35 ℃), interrupt circuit, focused transducer suspends emitting treatment, open B ultrasonic, observe the focused ultrasound therapy tumor effect by the B ultrasonic head; The skin surface temperature of top, zone to be treated drops to when exposing body surface initial temperature (as reaching below 30 ℃) in the treatment, connects circuit, and focused transducer continues next step emitting treatment.
The invention has the beneficial effects as follows: efficient, simple, practical, economic.
(1). efficient.The measurement temperature efficiency improves.
(2). easy.Complete unit is simple for production.
(3). practicality.Field conduct is very practical.
(4). economy.Significantly reduce use cost.
Description of drawings
Accompanying drawing is a sectional structural map of the present invention.
Among the figure: 1, focused transducer 2, B ultrasonic head 3, laser temperature-measuring device.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail.
In the drawings, focused transducer 1, B ultrasonic head 2, laser temperature-measuring device 3 are aimed at patient's area for treatment; When focused transducer 1 is opened laser temperature-measuring device 3 when launching ultrasonic therapy; Measuring temperature when laser temperature-measuring device 3 from the skin surface of patient's area for treatment heats up when surpassing the treatment exposed body surface initial temperature and heating up more than 5 ℃ (as reaching more than 35 ℃), interrupt circuit, focused transducer 1 suspends emitting treatment, open B ultrasonic, observe the focused ultrasound therapy tumor effect by B ultrasonic head 2; Treat that laser temperature-measuring device 3 drops to the treatment exposed body surface initial temperature from the skin measurement temperature of patient's area for treatment and connects circuit when (as to below 30 ℃), focused transducer 1 continues next step emitting treatment.
