Embodiment Construction

[0057] An ablation device 5 according to a particular embodiment of the invention is a surgical tool, depicted in FIG. 3 . The device 5 is preferably a cystoscope (or part of a cystoscope) and includes an elongated body portion 9 comprising a proximal end 5b and a distal end 5a.

[0058] At the distal end 5a of the device 5 there is a light input 8 (which may be omitted in some embodiments), a light source (not shown - may be omitted in some embodiments), an ablation module output 6, and a fluid Output 7. At the proximal end 5b of the device 5 there is a light output 10 (which may be omitted in some embodiments), an ablation module input 11 , and a fluid input 12 .

[0059] Optical input 8 preferably comprises a lens optically connected to a telescope (not shown), which extends the length of elongated body portion 9 of device 5 . A telescope is optionally connected to the light output 10 at the proximal end 5 a of the ablation device 5 .

[0060] The light output 10 may com...

Abstract

A surgical tool for use as an ablation device in a surgical operation including: an ablation module output configured to ablate a volume of material at a surgical site to form an ablated volume; a control module arranged to receive information indicative of the position of the surgical site; and a fluid output adapted to deliver fluid to the surgical site during a surgical operation such that at least part of the ablated volume is filled with fluid and the fluid is in direct contact with at least part of the surgical site. The control module is operable to control the flow rate of fluid delivered by the fluid output in response to the received information in order to control the position of the surgical site.

Description

technical field [0001] The present invention relates to a surgical tool for use as an ablation device and an ablation system. More specifically, said surgical tool is preferably a cystoscope. Background technique [0002] It is well known that in order to perform various surgical operations on a patient, it is necessary to use images of the patient, which were previously obtained, for example, by ultrasound imaging, X-ray imaging or magnetic resonance imaging. When choosing, for example, to remove a certain amount of bone in preparation for the patient to be fitted with an artificial joint, the surgeon can be guided by previously acquired images during such an operation. Robots are known to assist surgeons to varying degrees during such operations. [0003] However, if the patient's body part being operated on becomes mobile due to the operation, the images of the patient's operating part obtained in the early stage will no longer represent the real structure of the patien...
