Abstract
The utility model relates to a hand type injecting frequency probe attached with a negative pressure drainage core, which can effectively absorb and eliminate the hematocele at the radiating frequency position during conducting radiating frequency melting under extracorporeal circulation of heart surgical, so as to ensure the radiating frequency effect with convenient utilization and high reliability. The utility model comprises a probe, a metal radiating frequency electrode in the middle of the probe and two negative pressure absorb grooves at two sides of the electrode; The two negative pressure absorb grooves are connected with a negative pressure absorb pipe which passes through a hollow pole body together with leads of the electrode.
Description
One, technical field:
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of intracardiac radio-frequency probe of hospital handheld formula band vacuum suction that is applied to cardiac operation.
Two, background technology:
At present, hospital is when carrying out cardiac operation extracorporeal circulation downlink radio frequency ablation, and intracardiac hematocele is influential to radiofrequency ablation therapy, for this reason, needs during operation additionally to absorb hematocele with vacuum extractor.But can only absorb the pocket hematocele like this, undesirable to the effect of operation operating position.Still there is not a kind of apparatus that can absorb radio frequency position hematocele easily and effectively at present both at home and abroad.
Three, utility model content:
This utility model is in order to solve the weak point in the above-mentioned background technology, provide a kind of hospital handheld formula band vacuum suction intracardiac radio-frequency probe, it is when carrying out cardiac operation extracorporeal circulation downlink radio frequency ablation, can absorb the hematocele at radio frequency position most effectively, thereby guarantee the radio frequency effect, and easy to use, the reliability height.
For achieving the above object, the technical solution adopted in the utility model is:
The intracardiac radio-frequency probe of a kind of hospital handheld formula band vacuum suction, its special character is: comprise probe, probe is provided with the vacuum suction groove, and the vacuum suction groove links to each other with the vacuum suction pipe.
In the middle of the above-mentioned probe can be the metallic RF electrode, and the electrode both sides can be the vacuum suction grooves.
The lead of above-mentioned vacuum suction pipe and electrode passes the body of rod of hollow.
Have handle on the above-mentioned body of rod.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, this utility model has vacuum suction around electrode, can absorb the hematocele at radio frequency position most effectively, thereby guarantees the radio frequency effect;
2, this utility model does not need additionally to absorb hematocele with vacuum extractor, has reduced surgical operation step, has saved operating time;
3, this utility model is easy to use, the reliability height.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view of probe portion in this utility model;
Fig. 3 is the structural representation of probe bottom in this utility model.
Five, the specific embodiment:
Mainly form referring to Fig. 1, this utility model by probe 4, the body of rod 3, handle 2, lead and vacuum suction pipe 1.Probe 4 is provided with metallic RF electrode 5 and vacuum suction groove 6, has handle 2 on the body of rod 3, and the body of rod 3 and handle 2 are hollow structure, in have lead to link to each other with probe portion electrode 5, have vacuum suction pipe 1 to link to each other with vacuum suction groove 6.Referring to Fig. 2, Fig. 3, be metallic RF electrode 5 in the middle of the probe, electrode 5 both sides are vacuum suction groove 6.
During real work, row will pop one's head in during radio-frequency (RF) ablation and 4 contact with endocardium, open negative pressure, blood from 6 sucking-offs of vacuum suction groove, and is flowed out through vacuum suction pipe 1, thereby assurance electrode 5 places be dried clean, can open radio-frequency (RF) switch, go radio-frequency (RF) ablation.
Claims (4)
1, the intracardiac radio-frequency probe of a kind of hospital handheld formula band vacuum suction is characterized in that: comprise probe (4), probe (4) is provided with vacuum suction groove (6), and vacuum suction groove (6) links to each other with vacuum suction pipe (1).
2, the intracardiac radio-frequency probe of hospital handheld formula band vacuum suction according to claim 1 is characterized in that: be metallic RF electrode (5) in the middle of the described probe (4), electrode (5) both sides are vacuum suction groove (6).
