Abstract

A system 100 for curative RFA treatment of a treatment volume 300, the treatment volume comprising at least a part of a cancer tumor, the system being adapted to apply RF energy between an electrode arranged on an uninsulated ablating portion 124 of an RF probe 120 and another electrode 160. The RF probe 120 is comprised in a probe arrangement 400 also comprising an insertion tube 410 and a biopsy needle 430, and the insertion tube 410 is arranged to be inserted into a tumor together with the biopsy needle 430 pushed by means of a striking arrangement, remain inserted in the tumor when the biopsy needle 430 is retracted, and allow the RF probe 120 to be inserted into the cavity in the tumor created by the biopsy needle 430.

Claims (10)

1. System (100) for curative radio frequency ablation (RFA) treatment of a treatment volume (300) comprising at least a part of a cancer tumor by applying radio frequency (RF) energy between an electrode arranged on an uninsulated ablating portion (124) of an RF probe (120) and another electrode (160), wherein the RF probe (120) is comprised in a probe arrangement (400) also comprising an insertion tube (410) and a biopsy needle (430), and the insertion tube (410) is arranged to be inserted into a tumor together with the biopsy needle (430), remain inserted in the tumor when the biopsy needle (430) is retracted, and allow the RF probe (120) to be inserted into the cavity in the tumor created by the biopsy needle (430), the system (100) further comprising a striking arrangement (310), arranged to push the biopsy needle (430) and/or the RF probe (120) into the tumor in distinct strokes such that there is an interval between each stroke by means of a striking device (340), arranged within an impact housing (320) to be shot towards an impact peg (350) that extends from a proximal end (122) of the biopsy needle (430) and/or the RF probe (120), in such a way that the impact between the striking device (340) and the impact peg (350) pushes the biopsy needle (430) and/or the RF probe (120) fonNard, with a high acceleration, a distance that is defined by the length that the impact peg (350) extends into the impact housing (320).
2. System (100) according to claim1, wherein the striking arrangement (310) comprises a spring device (360), with which the impact peg (350) interacts, wherein the spring device (360) pushes the biopsy needle (430) and/or the RF probe (120) away from the striking arrangement (310), in such a way that the length that the impact peg (350) extends into the impact housing (320) becomes dependent of the force applied to the biopsy needle (430) and/orthe RF probe (120) to counteract the spring force in the spring device (360).
3. System (100) according to any one of claims 1-2, further comprising: a control arrangement (110); a temperature measuring arrangement (130), arranged to measure an RF probe temperature and based on this provide estimations of the treatment volume temperature (T) to the control arrangement (110); a cooling arrangement (140), arranged to be controlled by the control arrangement (110) to cool the RF probe (120); and an RF generating arrangement (150), controlled by the control arrangement (110) to, based on the estimated treatment volume temperature (T), supply the amount of RF energy to the RF probe (120) that is needed for a desired treatment volume temperature (TD) to be maintained.
4. System (100) according to c|aim 3, wherein the control arrangement (110) is arranged to, at selected intervals, shut offthe RF generating arrangement (150) and the cooling arrangement (140) for a selected shut-off period, to thereby allow the treatment volume temperature (T) to equalize.
5. System (100) according to c|aim 4, wherein the temperature measuring arrangement (130) is arranged to estimate the treatment volume temperature (T) based on a determination of the derivative of the measured RF probe temperature curve up to the end of the shut-off period.
6. System (100) according to c|aim 4 or 5, wherein the cooling arrangement (140) is arranged to cool the RF probe (120) by circulating cooling liquid, and to be turned off by stopping the circulation of the cooling liquid.
7. System (100) according to any one of claims 3-6, wherein the temperature measuring arrangement (130) comprises a thermocouple comprising a conductor (135) that is arranged inside the RF probe (120) and connected to the uninsulated ablating portion (124) of the RF probe (120).
8. System (100) according to any one of claims 3-7, wherein the cooling arrangement (140) comprises a .) cooling liquid supply channel (142) arranged inside the RF probe uninsulated ablating portion (124) ofthe RF probe (120). to supply cooling liquid to the
9. System (100) according to any one of claims 3-8, wherein the control arrangement (110) is arranged to monitor the RF energy supplied by the RF generating arrangement (150) to the RF probe (120), and turn off the RF generating arrangement (150) at the point in time (tps) when there is no longer any substantial lowering of the output power from the RF generating arrangement (150).
10. System (100) according to c|aim 9, wherein the determining of the point in time (tps) when there is no longer any substantial lowering of the output power from the RF generating arrangement (150) involves determining when the derivative ofthe output powerfrom the RF generating arrangement (150) comes within a predetermined threshold, close to zero.
