Description
Technical field
The utility model relates to a kind of laparoscope flexible Radio Frequency ablation needles.
Background technique
In recent years, the disease incidence of cancer rises year by year, and the malignant tumour that liver cancer is common as China, and operation excision is recognized
For the means for being only possible acquirement curative effect.But a big chunk patient has lost operation and has cut when finding liver cancer
The chance removed.According to incompletely statistics, only about 20% patient can receive Traditional surgical treatment.
With advances in technology, the development of instrument, Local physical ablation provide new thinking for the treatment of liver cancer, main
Include: radio-frequency ablation procedure, microwave ablation, laser ablation and cryoablation.Radio-frequency ablation procedure is because of its good safety
Property and validity it is most wide in clinical application prospect at present, it is all that the alternating current vibration to tumor tissues is conducted by electrode needle
The tissue ion enclosed, ion vibration cause frictional heat generation, and conduct to adjacent tissue, generate a spherical shape around electrode needle and ruin
Area is damaged, meets most tumors form, while being heated to about 60-90 degree close to the tissue of electrode, temperature high in this way can be true
Thermal protection damage area reaches preset range.Microwave ablation itself solidifies that stove range is smaller, and ablation stove is shuttle shape, and diameter is greater than
The tumour of 2cm is easy to happen residual tumor.It is costly that laser ablation uses and install fibreoptics, with RF ablation ratio without
Clear superiority.Cryoablation freezing is extremely larger, large area freezing and multiple spot freezing, it will usually cause severe complication, and recur
Rate is high, and cost of equipment is expensive, and clinical application is not extensive.
Radio-frequency ablation procedure is widely used in the surgical procedure for primary carcinoma of liver and metastatic liver neoplasm, is had
The advantages that effective in cure good, minimally invasive, few intercurrent disease, can even reach radical cure effect for part small liver cancer, and not can be carried out
The patient of radical excision provides complementarity therapy apparatus meeting.Most people thinks that diameter of tumor is less than 3cm, and quantity is less than or equal to
4 or diameter of tumor are less than 5cm, and quantity is less than or equal to 3, and diameter accumulation is less than 12cm, can reach preferable therapeutic effect.Mesh
Preceding clinically used ablation mode has: RF ablation and opening under ultrasound guidance and CT Percutaneous radiofrequency ablation ablation, laparoscope
Operation RF ablation.Percutaneous radiofrequency ablation ablation is small because having wound, restores fast feature, but percutaneous ablative is due to " two o'clock one
The limitation of line " is limited only to the lump of liver surface, and for position, lump deeper rearward and in liver is difficult to reach.It opens
It is larger to the damage of patient although abdomen is looked at lower RF ablation straight and definitely can reliably be treated to lesion, have centainly
Limitation.Laparoscope downlink radio frequency ablation is suitable only for tumour at present and is located at liver surface, or simultaneously as removal of lesions
Processing cannot the deeper multiple lesion in position simultaneously, liver failure caused by avoiding excessive operation on liver from cutting off.Advantage is:
It can be operated under direct-view in art, position more accurate, but the method for percutaneous ablative similarly limits it in liver back segment,
The application of the inferior privileged sites of diaphram.
