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, energy ablation technology clinical application range enlarges gradually, and the probe that research and development are adapted to different clinical practice demands just seems especially important.
Tumor tissues in the human organ comprises shape, size and the quality of regular and irregular.Conventional electrode catheter is definite shape substantially, and shape and size with tumor tissues in implementing ablative surgery do not conform to, always and the quality of tissue with the carrying out and change of ablative surgery, thereby cause the ablative surgery time lengthening, surgical effect is undesirable.Tumor tissues in some organ is because be difficult for demonstration and need to inject liquid helping to develop and locate at locating apparatus.If use different apparatus repeated punctures to locate, the efficient of then performing the operation reduces, and operating time prolongs.
Summary of the invention
But the objective of the invention is to design a kind of filling type formula probe electrode device that carries out radiofrequency ablation therapy effectively at tumor tissues in the human body, 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, form by handle, hand lever, preceding bar, sleeve pipe, handle joint and probe, the sleeve pipe front end is sharp-pointed shape, can be used for the tissue that punctures, probe has 1-15 root (commonly used is the 6-12 root), place in the sleeve pipe, wherein, having a probe at least is hollow tubular structure.Be provided with at least one interface at handle, hand lever or preceding bar position, be communicated with tubular probe.As passage from liquid (routine medicinal liquid, water etc.) to in-vivo tissue that carry; Probe is not accommodated in inside pipe casing when using; When operation, be punctured to tumor tissues with sleeve pipe.When the sleeve pipe puncture puts in place, push hand lever, the probe in the sleeve pipe is pushed out sleeve pipe and stretches in cannula tip, and penetrates tumor tissues equably.The length that probe stretches out is 0.5-3cm, and the maximum gauge that probe opens distribution is 2-7cm.When using this electrode assembly to carry out radio-frequency (RF) ablation in human body, tumor group is woven with bigger coverage rate, can obtain better therapeutic effect.
In this utility model, the interface on handle, hand lever or preceding bar can connect injection control device and/or sucking-off control device.Can inject liquid (as medicinal liquid, water etc.) to the site of puncture tissue by tubular probe.Perhaps organize sucking-off residual substance or gas etc. from the site of puncture by tubular probe.
When above-mentioned interface had only one, this interface can be alternately as inlet and suction outlet; When interface when being a plurality of, can a part as inlet, a part is decided according to the actual requirements as suction outlet.What device this interface also can not take over, and as the ventilation mouth in when operation.During as inlet, each inlet can inject different liquids as required as a plurality of interfaces.
In this utility model, described probe can all be a hollow tubular structure.Side, the front end position different directions of tubular probe, different loci can offer hole respectively, so that inject liquid, also be convenient to different directions, different loci sucking-off residual substance (as waste liquid etc.) etc. from tissue to the different directions of tissue, different loci.
In this utility model, described sleeve pipe front end position (thrusting that position of tissue) side different directions, different loci also can offer hole respectively.Inject or sucking-off liquid or gas to the tissue site of puncture by interface on the sleeve pipe and sleeve pipe itself.
In this utility model, the probe front position can be equipped with temperature sensor (comprising thermocouple type or semi-conductor type etc.), in conjunction with connecting automatic temperature-adjusting and energy management system, the variations in temperature of tissue during the operation of supervision radio-frequency (RF) ablation, control radio-frequency (RF) energy size makes more accurate, the safety of operation.
In this utility model, can be carved with scale label or location recognition sign on the sleeve pipe, be convenient to the operator and grasp the depth location that the understanding probe enters human body.
Tumor tissues in some organ can not show on ultrasonic instrument because bubble is too many.Use this electrode to be filled in the tumor tissues, help to develop, increase the visibility of ultrasonic instrument, thereby can accurately puncture tumor tissues, reach more effective ablation effect via liquid.
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 comprises handle, hand lever, preceding bar, sleeve pipe and handle joint etc., and its structure is seen shown in the accompanying drawing 1.Its middle probe adopts Ti-Ni marmem material or stainless steel material, and the diameter of every probe is 0.1-0.2mm.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 the covering tumor tissues that comes distributes.Operation finishes, and under hand lever was handled, probe drew in and places in the sleeve pipe.Perfusing hole is that standard interface (Luer) can connect different fluid flow (dosage) control device.
This utility model designed probe electrode structure is simple, and is easy to operate, and can select the probe of different shape sizes for use, and radio-frequency (RF) ablation is more effective, thereby can shorten treatment time, improves therapeutic effect.
