Benefits of technology

The present invention provides a treatment system that can apply a treatment to tissue while also stimulating nerves in that tissue using a separate stimulation unit. The system can then sense the electrical signal that results from the stimulation, and use that information to control the application of the treatment. This results in a more targeted and precise treatment that can potentially improve the effectiveness and safety of treating certain conditions.

Problems solved by technology

It is common that nerves are damaged during surgical procedures, resulting in malfunctioning of associated sensory and motor systems.

Embodiment Construction

[0017]Prior to the detailed description being set forth, it may be helpful to set forth definitions of certain terms that will be used hereinafter.

[0018]The terms “light-based” and “optical” as used in this application refer to electromagnetic radiation in the visible range as well as in the near infrared range.

[0019]The term “cold laser” as used in this application refers to a laser that is configured to ablate tissue while preventing stress waves or heat from propagating beyond the interaction volume relative to a shortest dimension of the interaction volume. For example, a cold laser may deliver pulses or fast trains of pulses having energy per pulse or per train of pulses that is sufficient to heat an interaction volume of the tissue above the spinodal decomposition threshold for water within the pulse duration, and cause sufficient pressure for ejection of the target tissue. Such a cold laser may have the duration of the pulse or the train of pulses selected to be sufficiently ...

Abstract

Treatment systems are provided, which comprise a treatment element applying a treatment to a tissue, a stimulation element optically stimulating nerves in the tissue, a sensing unit sensing an electrical signal produced by nerves in the tissue in response to the optical stimulation, and a control unit controlling the application of the treatment according to the sensed signal. The systems and methods are used to avoid damaging nerves by sensing them during operation and immediately before local treatment application and preventing energy emission when the treatment tool is too close to specified nerves. Additional electric stimulation may be provided to enable avoidance of nerve damages on a larger scale, the treatment may be applied by a cold laser, and the control unit may control the treatment in realtime and in a closed loop and immediate prevent further treatment upon sensing optically stimulated nerves.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to the field of invasive surgery, and more particularly, to treatment tools which avoid damaging nerves.[0003]2. Discussion of Related Art[0004]It is common that nerves are damaged during surgical procedures, resulting in malfunctioning of associated sensory and motor systems. At least some of the damage is not a necessary result in view of the surgical targets and is in principle avoidable. Current technology includes mapping and / or monitoring of nerves by measuring nerve or organ response to electrical stimulation.SUMMARY OF THE INVENTION[0005]One aspect of the present invention provides a treatment system comprising a treatment unit comprising a treatment element arranged to apply a treatment to a tissue, a stimulation unit comprising a stimulation element arranged to stimulate nerves in the tissue, a sensing unit comprising a sensing electrode arranged to sense an electrical signal produced by...
