Description
Technical field
This utility model relates to a kind of auxiliary facilities of microwave ablation treatment, relates in particular to a kind of electrode needle fixed clamp device of microwave ablation therapeutic equipment.
Background technology
Along with the medical image technical development, Minimally Invasive Surgical Technology has remarkable break-throughs in recent years, and wherein, the microwave ablation therapy under the ultrasonic guidance is an impressive progress of minimally invasive surgery.The microwave ablation therapy is a kind of new tumor therapeuticing method, and is image-guided down at B ultrasonic or CT, and the electrode needle of micro-wave therapeutic is inserted body tumor tissue, and tumor is carried out thermal ablation therapy.This therapy is significantly less than corresponding traditional surgery to patient's wound.
Yet; Existing microwave ablation therapeutic equipment is in therapeutic process, and its electrode needle is fixed by manual work fully, i.e. the interior microwave of electrode needle insertion tumor tissues begins radiation to ablation and finishes; In the microwave radiation process; Electrode needle is by manual work support or operating forceps clamp, is displaced to patient's respiratory movement with prevention electrode needle in melting and melts outside the target, causes the normal surrounding tissue hot injury.
But the artificial electrode needle poor stability of helping is in case needle body rocks the dark excessively affected area of easy implantation; In addition, operating forceps clamp electrode needle stability increases, but operating forceps is longer, and ultrasonic probe is detected the supervision ablation procedure in real time in the obstruction microwave ablation in the thermal field scope.
Summary of the invention
A kind of microwave ablation therapeutic equipment electrode needle fixation clamp that this utility model provides, prevention electrode needle displacement or deviate from outside melting kitchen range is eliminated the focus that melts that causes because of the electrode needle displacement and is organized the hot injury outward.
For realizing above-mentioned technique effect; This utility model provides a kind of electrode needle fixation clamp of microwave ablation therapeutic equipment; Comprise: train wheel bridge and lower plate; The train wheel bridge of said electrode needle fixation clamp is provided with first arcuate groove, and the lower plate of said electrode needle fixation clamp is provided with second arcuate groove relative with train wheel bridge first arcuate groove.
Preferably, the inwall of the inwall of said train wheel bridge first arcuate groove and lower plate second arcuate groove is provided with anti-skidding stricture of vagina respectively.
Preferably, the inwall of the inwall of said train wheel bridge first arcuate groove and lower plate second arcuate groove Improved mat that bonds respectively.
Preferably, the agglutinating Improved mat of the said first arcuate groove inwall is provided with semi-cylindrical hill, and the agglutinating Improved mat of the said second arcuate groove inwall is provided with semi-cylindrical hill.
A kind of electrode needle of microwave ablation therapeutic equipment, holding electrode pin fixation clamp on the needle body of this electrode needle.
The electrode needle fixation clamp of a kind of microwave ablation therapeutic equipment of this utility model; Its advantage is that upper and lower clamping plate are provided with the first relative arcuate groove and second arcuate groove, and electrode needle is clamped in first arcuate groove and second arcuate groove; The electrode needle wall contacts with the inwall of first arcuate groove, the internal face of second arcuate groove; Between upper and lower clamping plate and the electrode needle frictional force is arranged, electrode needle displacement in the prevention ablation procedure forces electrode needle accurately to be fixed in and intends the lesions position that melts; The prevention electrode needle is deviate to predetermined thermal field scope, and kitchen range surrounding tissue hot injury is melted in prevention.
