Description
Technical field
The present invention relates to a kind of ablating device and probe thereof for the treatment of atrial fibrillation.
Background technology
Atrial fibrillation (atrial fibrillation) is a major challenge that current medical science faces, and the treatment of atrial fibrillation remains the weakest link in the current treating irregular heart pulse.Though at present the treatment for atrial fibrillation has proposed a lot of methods, for example Drug therapy, operative treatment, no wound radio-frequency ablation procedure etc., these methods all have its limitation.Make when healing with medicine, the high person's side effect of curative effect of medication is big, the shortcoming of few side effects person weak curative effect, antiarrhythmic drug long-term treatment weak curative effect.Surgical operation to separate or to interrupt the path of turning back that causes atrial fibrillation, is protected the transportation function in atrium by set up linear damage in the atrium simultaneously.The operation method of surgical intervention is at present performed the operation " labyrinth ".But operative treatment complexity, time-consuming, wound are big and certain early complication and case fatality rate arranged.
Therefore, the no wound ablation techniques of treatment atrial fibrillation has obtained paying close attention to widely.
Radio-frequency (RF) ablation (RFCA) is the method for at present more satisfactory treatment atrial fibrillation, and has become conventional therapy means.
High intensity focused ultrasound (HIFU) is the no wound ablation techniques of new development.It is gathered in ultrasonic energy by ultrasonic mirror a certain target spot of body deep tissue, make that local cells is heated, cavitation and mechanically deform, final bland necrosis, do not focus on target spot tissue in addition but do not damage, need not to cut skin, just can fix a point to melt and isolation external intracorporeal organ is organized and implemented.Its characteristics are not possessed by radio-frequency electrical energy, microwave electric energy and laser energy, are the desirable technique of starting no wound surgery.
Adopt at present the ablating device of treatment atrial fibrillation such as ultrasonic, radio frequency, some be external or the outer ablating device of the heart, energy pop one's head in and diagnostic probe external, distance, inaccuracy, therapeutic efficiency is low, operates stupid.
In addition, the catheter ablation device is arranged also, it uses transvenous catheter with the intra-auricular small region of calcination, destroys and facilitates the myocardial cell of atrial tachycardia.In such therapy equipment, probe is pressed close to health, and contact tissue be not easy to probe and reused by other patients, and such treatment has certain wound.
Summary of the invention
The purpose of this invention is to provide a kind of probe for the treatment of the ablating device of atrial fibrillation and being used for this device, overcoming present external ablation techniques therapeutic effect instability, to melt terminal point and be difficult to hold, and the probe of the ablation techniques of transvenous catheter such as is not easy to use repeatedly at problem.
The invention provides a kind of ablating device for the treatment of atrial fibrillation, it comprises: a probe, described probe comprise a plurality of diagnostic probe and a plurality of energy probe, and described a plurality of diagnostic probe and a plurality of energy probe are alternately arranged with each other; The diagnostic equipment that is connected with diagnostic probe; The energy generating apparatus that is connected with the energy probe.
Described probe also comprises a flexible jacket, to wrap up described diagnostic probe and energy probe.
Described energy probe is radio frequency or ultrasonic energy probe.
Described diagnostic probe is the ultrasonic diagnosis probe.
Described probe is suitable for entering in the body with diagnosis and treatment atrial fibrillation through esophagus.
Described flexible jacket can comprise a cavity, the fluid that wherein can circulate and need, for example liquid coolant; This cavity can be connected with a circulating device.
The invention provides a kind of probe that is used for the atrial fibrillation ablating device, described probe comprises a plurality of diagnostic probe that are connected with the diagnostic equipment; With a plurality of energy probes that are connected with energy generating apparatus; Described a plurality of diagnostic probe and a plurality of energy probe are alternately arranged with each other.
Described probe also comprises a flexible jacket, to wrap up described diagnostic probe and energy probe.
Described energy probe is radio frequency or ultrasonic energy probe.
Described diagnostic probe is the ultrasonic diagnosis probe.
Described probe is suitable for entering in the body with diagnosis and treatment atrial fibrillation through esophagus.
The invention provides a kind of method of using the atrial fibrillation therapy device, this atrial fibrillation therapy device comprises: a probe, described probe comprise a plurality of diagnostic probe and a plurality of energy probe, and described a plurality of diagnostic probe and a plurality of energy probe are alternately arranged with each other; The diagnostic equipment that is connected with diagnostic probe; The energy generating apparatus that is connected with the energy probe;
This method comprises:
Described probe is stretched into through esophagus,
The monitoring of the use diagnostic equipment, thus probe can be positioned at centrifugal dirty nearer position;
Further use diagnostic equipment monitoring, adjust probe, make described a plurality of energy probe be positioned the position that needs;
Start the disorganization of energy probe with the determination portion position of heart.
Device of the present invention is not performed the operation no wound through esophagus; Nearer apart from heart, precision can be than higher, and the therapeutic efficiency height is effective; And probe can be reused by different patients easily; In addition, the structure of device is compact, operates more convenient.It combines the advantage of transvenous catheter ablation and external ablation, and has overcome its shortcoming.
Description of drawings
Fig. 1 is the sketch map of ablating device of the treatment atrial fibrillation of one embodiment of the invention.
The specific embodiment
As shown in Figure 1, the ablating device of treatment atrial fibrillation of the present invention comprises a probe 10, and described probe comprises a plurality of diagnostic probe 1 and a plurality of energy probe 2.These diagnostic probe and energy probe alternately are arranged in the flexible jacket 3, form elongated pipe.The quantity of diagnostic probe and energy probe can be determined as required.
Energy probe 2 can be radio frequency or ultrasonic energy probe, for example HIFU; Energy generating apparatus 7 can be a power generator.
Probe 10 size and length are made and are suitable for entering in the body with diagnosis and treatment atrial fibrillation through esophagus, can not use seal wire.
This ablating device can link to each other with other connecting devices 6, so that transmission, other information or materials that need that circulate, and liquid coolant for example, this moment, these other connecting devices 6 were a circulating device.
Described flexible jacket 3 can comprise a cavity, the fluid that wherein can circulate and need, for example liquid coolant; This cavity can be connected with circulating device 6.Certainly, such cavity not necessarily, but optionally.
During use, the staff stretches into described probe 10 through esophagus, and diagnostic probe 1 is surveyed in real time and the information that obtains is delivered to the diagnostic equipment.The staff uses the diagnostic equipment 5 monitorings, so that the staff can progressively be positioned at probe centrifugal dirty nearer appropriate position.Simultaneously, further use the diagnostic equipment 5 monitorings, adjust probe 10, make described a plurality of energy probe 2 be positioned the position that needs.After having determined that the energy probe has been positioned at appropriate position, use energy generating apparatus 7 to start energy probe 2, for example produce high intensity focused ultrasound (HIFU) energy, specific part (being target spot) for heart heats, disorganization with the determination portion position (being target spot) of heart, thereby reach the purpose of treatment atrial fibrillation, can start circulating device 6 simultaneously, with cooling probe.
