Abstract
The utility model discloses a local single-needle single-side radio frequency ablation electrode which comprises a metal conduit with the front end face as an inclined face. An insulation sleeve is sleeved on the outer wall of the metal conduit, and a notch is formed on one side of the front end of the insulation sleeve. The insulation sleeve and the metal conduit are in interference fit. By arranging the insulation sleeve on the outer wall of the metal conduit in a sleeved mode and arranging the notch on the lateral wall of the front end of the insulation sleeve, a part of the metal conduit is exposed, and the size and the shape of the notch can be determined according to clinical requirements. When radio frequency energy is transmitted, the radio frequency energy can be conducted to the exposed portion of the metal conduit, other portions of the metal conduit can be surrounded by the insulation sleeve on the outer wall of the metal conduit, the radio frequency energy can not be transmitted out, local precise radio frequency energy transmitting is achieved, radio frequency ablation is conducted on a lesion tissue requiring radio frequency ablation, and damage to important organs, blood vessels or nerves near the lesion tissue is avoided.
Description
Technical field
This utility model relates to a kind of radio-frequency ablation electrode of technical field of medical instruments, particularly the accurate radio-frequency ablation electrode in a kind of part.
Background technology
The tumor radio-frequency ablation procedure is as Wicresoft's means, obtain good effect in solid tumor treatments such as liver, kidney, lungs, its curative effect obtains clinical approval, but for close important organ, when blood vessel or nerve etc. were located the radiofrequency ablation therapy of tumor, doctor's operation easier was very big.Because existing tumor radio-frequency ablation electrode does not all have local one-sided radio-frequency ablation electrode, it all is one pole and bipolar; Product design is single needle and spininess.The kitchen range that melts that this class electrode forms is the oval or spherical of symmetry more, is not suitable near important organ the radiofrequency ablation therapy of the tumor of blood vessel or nerve etc.
The utility model content
The purpose of this utility model is to provide a kind of ablating electrode of realizing local accurately emission radio-frequency (RF) energy.
The one-sided radio-frequency ablation electrode of this local single needle that this utility model provides comprises that front end face is the metal catheter on inclined-plane, and the outer wall of metal catheter is with insulated sleeve, and front end one side of insulated sleeve is jagged.
It is interference fit between described insulated sleeve and the metal catheter.
This utility model closely is with insulated sleeve at the outer wall of metal catheter, front end side wall at insulated sleeve is offered breach, allow the part of metal catheter expose out, the size of breach and shape can be determined according to clinical needs, when launching, the radio frequency amount can be transmitted to the exposed part of metal catheter, and other parts of metal catheter are surrounded by the insulated sleeve of its outer wall, the radio-frequency (RF) energy conduction is not gone out, thereby realized the emission of local accurate radio-frequency (RF) energy, with realization the pathological tissues that needs radio-frequency (RF) ablation is carried out radio-frequency (RF) ablation, and to its vitals that close on, blood vessel or neural not damage.
Description of drawings
Fig. 1 is the main TV structure sketch map of this utility model preferred embodiment.
Fig. 2 is the A-A enlarged diagram among Fig. 1.
The specific embodiment
Preferred embodiment, as shown in Figure 1 and Figure 2, the one-sided radio-frequency ablation electrode of this local single needle that this utility model provides comprises that front end face is the metal catheter 1 on inclined-plane and the insulated sleeve 2 that closely is placed in its outer wall, front end one side jagged 21 of insulated sleeve 2.Be interference fit between insulated sleeve 2 and the metal catheter 1, be beneficial to tight connection between the two.The size of breach 21 is 1/2 circle, makes the area that melts focus bigger like this.
During use, with the rear end connection lead of metal catheter 1, lead links to each other with the radio-frequency (RF) ablation instrument.When the radio frequency amount can be launched, the exposed part that metal catheter 1 is positioned at breach 21 places can be launched the radio frequency amount focus is implemented to melt, and other parts of metal catheter 1 are surrounded by the insulated sleeve of its outer wall, radio-frequency (RF) energy is prevented from outside emission, thereby realized the emission of local accurate radio-frequency (RF) energy, with realization the pathological tissues that needs radio-frequency (RF) ablation is carried out radio-frequency (RF) ablation, and to its vitals that close on, blood vessel or neural not damage.
Claims (2)
1. the one-sided radio-frequency ablation electrode of local single needle comprises metal catheter, it is characterized in that: the front end face of described metal catheter is the inclined-plane, and the outer wall of described metal catheter is with insulated sleeve, and front end one side of insulated sleeve is jagged.
2. the one-sided radio-frequency ablation electrode of local single needle as claimed in claim 1 is characterized in that: be interference fit between described insulated sleeve and the metal catheter.
