2) Jiao Qu.Burnt district self-energy deposits in a large number, the temperature that is positioned at tissue was wherein reached more than 65 ℃ at several seconds, cause organizing producing instantaneous coagulation necrosis, and outer the organizing of Jiao Qu only has a spot of energy deposition, so injury-free substantially, finally reach the purpose of targeted therapy tumor.
Allergic rhinitis are a kind of common chronic diseases, and its global sickness rate has reached 15%～20%, and allergic rhinitis are the allergic diseases that occur in nasal mucosa, have a strong impact on patient's quality of life, the inflammation of the adjacent organs that more may occur together.Since unclear for the pathogeny of allergic rhinitis, can't suit the remedy to the case, so medicine is also bad to the effect of allergic rhinitis, and the effective treatment means of generally acknowledging both at home and abroad is to alleviate allergy with concha nasalis inferior zone attenuation at present.Treatment means commonly used is operative treatment and ablation therapy, perform the operation and the area for treatment that melts in the concha nasalis inferior zone, require under the situation of not damaging nasal mucosa, to remove part mucosa undertissue as far as possible.Operative treatment can cause than macrolesion nasal mucosa usually, can bring sequela.Ablation therapy comprises radio frequency, laser, plasma.Focus supersonic not only can make the Submucosa tissue necrosis, destroy the local immunity cell, reduce the cytokine and the inflammatory mediator of its release, reduce nerve excitability by destroying the tela submucosa neurocyte, and alleviate the rhinitis symptom, and to almost not damage of nasal mucosa, at present domestic have the minority clinical research to show that focus supersonic is fine to the treating allergic rhinitis effect.The nasal cavity space is narrow and small, and therapentic part is special, and traditional focus supersonic probe can not meet the demands, and needs a kind of novel line focusing ultrasonic therapy probe.
Find through retrieval prior art, Chinese invention patent publication number: CN101141996, title: comprise to be integrated in and treat the treatment intracavitary probe of using the image transducer in the ultrasonic transducer, this probe comprises: the supporting mass that is formed with conduit, conduit is extended by the securement head that is used at least one therapeutic transducer element, and transducer element has the effective surface area of emission concentration ultrasonic and comprises having the spherical positive of total surface area.The main body of this probe is a sphere self-focusing transducer element, diameter is between 33mm～40mm, contrast with the present invention, this probe also is to be used for intracavitary therapy, but its volume is much bigger, and the focus supersonic of generation becomes point-like, and intensity is bigger, energy is wayward during treatment, should not be used for the treatment of disease in the narrow and small cavity.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of line focusing ultrasonic therapy probe is provided, done technological improvement on the basis to traditional ultrasonic therapeutic probe, ultrasonic side at probe is focused into wire, burnt territory is a rectangle, ultrasonic energy disperses, and sweep limits is big and little to mucosa injury.
The present invention is achieved by the following technical solutions, the present invention includes: shell, treatment window, ultrasonic transducer and conduit, wherein: ultrasonic transducer is fixed in the inside of shell, the top of shell is a sphere, the bottom of shell is provided with sleeve pipe, the treatment window is located at the side of shell, and the two ends of ultrasonic transducer are fixed on the treatment window, and conduit links to each other with ultrasonic transducer.
Described ultrasonic transducer is that piezoelectric ceramics is made, and length is 4～6mm, and the cross section of ultrasonic transducer is an arc, radius is 4～6mm, radian is 60 °～90 °, and the arc two ends of ultrasonic transducer and treatment window are fixedly linked, and the depth of focus is being treated 3～5mm outside window.
Described treatment window is a rectangle, and its size is identical with ultrasonic transducer.
Described shell is a cylinder, and the top of shell is a sphere, removes treatment on the shell and all is covered with air bag outside window.
Be provided with water inlet pipe, outlet pipe and cable in the described sleeve pipe, cable links to each other with ultrasonic transducer, and water inlet pipe and outlet pipe are cast in the bottom of shell.
The diameter of described water inlet pipe and outlet pipe is that metal is made less than 2mm.
Described shell is that rustless steel is made, and size is less than 8mm*8mm*8mm.
Be covered with biocompatible thin film on the described shell.
When the present invention works, probe is extended intranasal concha nasalis inferior zone, the treatment window is close to concha nasalis inferior, and focus supersonic focuses on 3～5mm zone under the mucosa, and probe advances the scanning of finishing the concha nasalis inferior zone toward the place ahead.Scanning area is a rectangle, and width is the width of ultrasonic transducer, and length is the distance of probe forward impelling.
The present invention has the following advantages compared to existing technology: the present invention has done technological improvement on the basis of traditional ultrasonic therapeutic probe, ultrasonic side at probe is focused into wire, burnt territory is a rectangle, and ultrasonic energy disperses, and sweep limits is big and little to mucosa injury.Less and the outsourcing air bag of probe diameter and length is to the full extent to having reduced the damage of nasal cavity inwall.
