Abstract
The utility model pertains to the technical field of medical apparatus, in particular to a probe electrode assembly for the treatment of radio frequency and ablation. The assembly is formed by connecting a handle, a sleeve and a probe; wherein, the probe with a bend angle is arranged on the front end of the sleeve, the end of the probe is a bevel and the end of the bevel is only head-shaped. When in use, impelling a handspike to make the sleeve and the probe enter into the interior of the body along the natural cooling channel. During the process of entering, the inner wall of the cavity will not be harmed by the very sharp line of the probe. When in contact with tumor tissue, adding appropriate obverse thrust will puncture the tissue, and then introduce the energy of radio frequency to realizing the ablation treatment. During the treatment operation, the device can be used independently or under the leading of real-time ultrasound.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of energy delivery and outut device that the radio-frequency (RF) ablation of the treatment soft tissue of human body (comprising tumor) is hindered by Wicresoft that be used for.
Technical background
Report the earliest about heat energy treatment tumor is early stage Egyptian and Greek treat superficial tumor with thermocauterization record.In general, according to histological types and concrete condition, heat energy causes do not wait from 3 to the 50 hours time of primary cellular defect needs, when temperature is increased to greater than 42 ℃, causes the needed time of primary cellular defect to be index decreased.For example, when temperature reaches 46 ℃, need 8 minutes kill tumor cells, and when temperature reaches 51 ℃, only need 2 minutes just can the kill tumor cell.When temperature surpasses 60 ℃, the intracellular protein degeneration, two lipid films melt, and cell death is inevitable.Studies show that there is certain physiological regulation defective in newborn tumor vessel, and cryogenic toleration is better than normal cell, and pyritous toleration is more normally organized poor.
Radio frequency produces heat energy and causes the focus that tissue necrosis more and more becomes research and clinical practice in recent years.When using radiofrequency ablation therapy, the high-frequency alternating current of probe tip is injected the probe surrounding tissue, and the ion in the tissue also just changes along with the change of the sense of current, thereby frictional heat, when the temperature of tissue surpassed 60 ℃, regional organization's necrosis appearred in cell death around probe.The radio-frequency (RF) therapy technology of standard can make the local organization temperature surpass 100 ℃, makes destination organization and tissue generation coagulation necrosis on every side.
In recent years, along with the expansion gradually of energy ablation technology clinical application range, the probe that research and development are adapted to different clinical practice demands just seems especially important.
In the human organ hollow lumen such as similar uterus exist certain crooked in tract, conventional electrode catheter is entering in the body along natural tract in the body is logical, in the progressive process of tumor tissues, damage normal tract inwall because of the too sharp-pointed or most advanced and sophisticated bent angle of probe is not enough.And the sleeve pipe integral intensity is too little, cannot push interior wall tissue open and arrives tumor tissues accurately.When melting, too much or not enough because of not having temperature control to melt, thus cause operating time to prolong, surgical effect is undesirable.
Summary of the invention
The objective of the invention is to design and a kind ofly enter via natural tract in the body effectively, tumor tissues is carried out the probe electrode device of radiofrequency ablation therapy.This apparatus structure is simple, easy to operate, and can shorten operating time, improves surgical effect.
This utility model is designed for the probe electrode of radiofrequency ablation therapy, is the improvement to existing similar probe electrode device.Wherein, sleeve pipe has elasticity, and probe is a bent angle probe, places tube ends, and probe tip has an inclination angle, and the tip, inclination angle is blunt nosed.
In this utility model, sleeve pipe and probe diameter are 2.5-5mm, and telescopic length is 8-25cm, and the probe bent angle is the 0-80 degree, and the length of probe is 5-20mm, and the inclination angle of probe is 20 degree-60 degree, and most advanced and sophisticated blunt nosed is circular arc.
Promoting hand lever during use makes sleeve pipe and probe enter in the body along natural tract in the body is logical.In the process that enters, cavity inner wall too sharply is not compromised because of probe, when touching tumor tissues, adds the suitable positive thrust tissue that can puncture.Import radio-frequency (RF) energy again, can reach the purpose of ablation.In the treatment operation, this device can use alone or use under the guiding of real-time ultrasound.
This utility model designed probe electrode structure is simple, and is easy to operate, and the accuracy height, thereby can shorten treatment time, improves therapeutic effect.
Description of drawings
Fig. 1 is this utility model probe electrode structure drawing of device.
Number in the figure: 1 is probe, and 2 is sleeve pipe, and 3 is handle, and 4 is the handle joint, and 5 are temperature sensor.
The specific embodiment
Further describe this utility model below in conjunction with drawings and Examples.
Concrete electrode structure as shown in Figure 1, by handle joint 4, handle 3, sleeve pipe 2 and probe 1 through forming.Handle 3 Chinese physician that is used to perform the operation grips electrode, and handle joint 4 is used to provide power supply, energy and the control signal of probe.Wherein the structure of handle joint 4 and handle 3 is similar with annexation and existing similar electrode, will not repeat here.
In addition, scale or position recognition mark are arranged on sleeve pipe or the probe, user can be known the degree of depth that probe inserts in use immediately.Surface-treated layer is arranged on the probe, and this processing layer can be to have certain roughness or slick coating, helps the visibility of ultrasonic instrument and the tumor tissues that can puncture accurately reaches more effective ablation.
Temperature sensor (comprising thermocouple type or semi-conductor type) can be housed on the probe of this electrode, cooperate the automatic temperature-adjusting/energy management system on backstage, can make operation safer more accurate.
The probe electrode structure similar that this utility model designed probe electrode, the structure of other parts and at present common radio-frequency (RF) ablation are used also comprises handle sleeve and handle joint etc., and its structure is seen shown in the accompanying drawing.Its middle probe adopts the Ti-Ni marmem material, and the diameter of probe is 2.5-5mm.When adopting memorial alloy, probe reaches the most effective ablation effect because variation of temperature can change the default angle of probe when operation.
The intravital radiofrequency ablation therapy in the available chamber of probe electrode device in the example.As the treatment of uterus tumor, practice shows that its treatment time can shorten greatly, and therapeutic effect is significantly improved.
In addition, electrode catheter also can adopt stainless steel material, is applicable in the product of low side comparatively.
