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.
Along with the energy ablation continuous advancement in technology, probe is also derived gradually by traditional monopolar radio frequency pin and is developed the multi-pole rf pin.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.
Tumor tissues in the human organ or tract inwall comprise rule and irregular shape and size. and conventional electrode catheter is definite shape substantially, shape and size with tumor tissues or tract inwall in implementing ablative surgery do not conform to, thereby cause operating time to prolong, surgical effect is undesirable.
Summary of the invention
The objective of the invention is to design a kind of blunting probe electrode assembly that carries out radiofrequency ablation therapy effectively at tumor tissues in the human body or tract, inner-walls of duct, this apparatus structure is simple, easy to operate, and can shorten operating time, improves surgical effect.
The probe electrode that is used for radiofrequency ablation therapy of this utility model design is built-in with the total 1-15 root of probe, and probe tips is blunt shape, as circle, arc etc.Be accommodated in inside pipe casing when not using, the sleeve pipe front end is sharp-pointed shape when operation, can be punctured in tumor tissues or the pipeline by sleeve pipe.Put in place when sleeve pipe punctures, during the pushing hand lever, the probe in the sleeve pipe is pushed out sleeve pipe and stretches in cannula tip.When probe stretched, many probe distribution were different shape, can be used for strutting the tract of tissue, are convenient to carry out radiofrequency ablation therapy.The length that probe stretches out sleeve portion is 0.5-3cm, and the probe maximum gauge that trails is 2-7cm.When using this electrode assembly to carry out radio-frequency (RF) ablation in human body, tumor group is woven with bigger better coverage rate, can obtain better therapeutic effect.
This probe electrode device can be equipped with temperature sensor (comprising thermocouple type or semi-conductor type) on probe, cooperate the automatic temperature-adjusting/energy management system on backstage, can make operation safer more accurate
This probe electrode device can have scale or position recognition mark on sleeve pipe.User can be known the degree of depth that probe inserts in use immediately.
This probe electrode device, its cannula tip can be passed through surface treatment, and for example roughness is handled or coating is handled, and helps the visibility of ultrasonic instrument and the tumor tissues that can puncture accurately.Reach more effective ablation.
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, hand lever, preceding bar, sleeve pipe and handle joint etc., and its structure is seen shown in the accompanying drawing.Its middle probe adopts Ti-Ni marmem material or stainless steel material, and the diameter of every probe is 0.01-0.2mm.Owing to be memorial alloy or stainless steel material (having elasticity), probe under hand lever is handled, stretches out in sleeve pipe when operation, launches, and distributing comes to contain covers tissue surface.Operation finishes, and under hand lever was handled, probe drew in and places in the sleeve pipe.
This utility model designed probe electrode structure is simple, and is easy to operate, and the probe of optional different shape size, and radio-frequency (RF) ablation is more effective, thereby can shorten treatment time, improves therapeutic effect.

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 6, handle 5, hand lever 4, preceding bar 3, sleeve pipe 2 and probe 1 through forming.Probe tips is rounded.Probe 1 is accommodated within the sleeve pipe 2 when flat.Probe 1 is stretched out from sleeve pipe 2 and present stretch-like by handle 5 push-and-pulls.Hand lever 4 and preceding bar 3 Chinese physician that is used to perform the operation grips electrode, and handle joint 6 is used to provide power supply, energy and the control signal of probe.Wherein the structure of handle joint 6, handle 5, hand lever 4 and preceding bar 3 is similar with annexation and existing similar electrode, will not repeat here.
After probe stretched out sleeve pipe, the extended configuration of probe can be rule or irregular shape.Can be used for strutting the human intracavity road, or strut tissue and become pocket-like, be convenient to carry out effective radio-frequency (RF) ablation (as shown in Figure 3).In addition, probe can be made with the resilient flexible metal material, can fill irregular space with pressure, and irregular inwall is carried out radio-frequency (RF) ablation (as shown in Figure 4).
Probe generally has the 6-15 root, adopts Ti-Ni marmem, and the diameter of every probe is 0.1mm, stretch out be launched into stretch shape after, extension elongation is 1-3cm, intermediary maximum gauge is 1-5cm.When not using at ordinary times, the operation hand lever places sleeve pipe 2 with the probe contraction.These intravital radiofrequency ablation therapies in available chamber of probe electrode device.As the treatment that vein blood vessel, endometrium and esophagus inwall melt, practice shows that its treatment time can shorten greatly, and therapeutic effect is significantly improved.
