Description
Technical field
The utility model belongs to medical instruments field, is related to a kind of tumour RF ablation device.
Background technique
RF ablation shank is the critical component in radiofrequency ablation therapy system.It has to Guan Chong RF ablation effect
The effect wanted.The working end length of RF ablation shank and the shape of working end directly determine the range of ablated tumor volume, with
And the completeness of ablation range.Shank is pierced into tumour when use and is melted, some current ablating devices had been pierced into
Cheng Hou can only adjust the position of shank due to not judged the position of tumor vicinity, and electrode needle is using relatively difficult, accurately
Degree is not high, inflexible.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of tumour RF ablation device, can externally needle tubing into
The a small amount of displacement of row, makes shank reach ideal site before puncture, improves the efficiency of operation.
In order to achieve the above objectives, the utility model provides the following technical solutions:
A kind of tumour RF ablation device, including shank, outer needle tubing, lever, electrode push rod, the shank are arranged hollow
Outer needle tubing in, the needle point of the shank is equipped with the sub- needle of umbrella, and the head of shank is stretched out out of outer needle tubing, and tail portion is connected with
For pushing the electrode push rod of shank, the lever is set in outside outer needle tubing, and by the way that the screw thread on the outside of outer needle tubing is arranged in
Section is threadedly coupled with outer needle tubing, the thread segment include the first thread segment, the second thread segment and be arranged in the first thread segment and
Axle journal between second thread segment, the both ends of the lever also are provided with corresponding thread segment, and centre is equipped with and is shorter in length than the axis
The clear band of neck.
Further, the electrode push rod includes push top, push rod and tailstock, and the push top is arranged inside outer needle tubing, front end
It is contacted with the tail portion of shank, rear end connects tailstock by push rod, and the push rod is connect with outer needle tubing internal whorl, by rotating tail
Seat, push rod move axially while driving push top rotation.
Further, the material of the sub- needle is memory alloy material.
Further, the quantity of the sub- needle is 6.
Further, the outside of the outer needle tubing is equipped with a layer insulating.
The utility model has the beneficial effects that: the present apparatus externally can carry out a small amount of displacement by needle tubing, wearing shank
Reach ideal site before thorn, improves the efficiency of operation.
