Problems solved by technology

[0009] However, when treatment is performed at a distance from the target, for example using focused ultrasound (HIFU) or via interstitial lasers or radiofrequency needles, the nerves cannot be accessed directly and, therefore, non-invasive localization for precise localization of these nerves or structures more generally is required Method and device for non-invasive localization

Embodiment Construction

[0025] For simplicity, only one nerve is referred to in the following description as an example of a target structure located using the non-invasive localization apparatus and method of the present invention. Of course, the present invention can also be used to locate structure types other than nerves, whether these structures are located in vivo or in other kinds of objects.

[0026] First, see figure 1 , to describe in detail various components of the positioning device of the present invention.

[0027] Firstly, the device comprises an acoustic wave emission source 1 which may advantageously be an ultrasound transducer for generating an ultrasound beam Fu. Preferably, the ultrasound transducer is of the HIFU type so that an ultrasound beam focused at a precise focal point can be produced. The transducers can also be of the type with a linear array. as from figure 2 It can be seen that the transducer 1 may comprise a cavity filled with a coupling liquid through which t...

Abstract

The device has a bar type high intensity focused ultrasound transducer (1) producing a beam of ultrasounds (Fu) through an external surface (Se) in a body zone till a target structure e.g. recurrent laryngeal nerve (N2), of a patient. A monitoring unit (3) e.g. endoscope, detects a response of the structure when the structure is subjected to stimulation. A medical imaging apparatus i.e. ultrasonic probe (2), is coupled to an ultrasonograph and to the transducer for visualizing a position of the beam in the body zone on a visualizing screen. An independent claim is also included for a method for non-invasive marking of a position of a target structure.

Description

technical field [0001] The present invention relates to the non-invasive localization of structures, such as nerves, within regions of the body. This positioning may be a step prior to treating tissue adjacent to the structure. Background technique [0002] In the medical field, it is often necessary to locate nerves, especially motor nerves, for example to stimulate muscles, or to avoid damaging the nerves when treating nearby tissue. [0003] Usually, the approximate location of the nerve is known from an anatomical map, but it is important to know the exact location of the nerve in the area of ​​the body, given that it is often desirable to protect the nerve, for example, when a therapeutic action is to be performed in close proximity to the nerve. The therapeutic act may be an anatomical procedure, or may involve the application of energy, such as ultrasound energy, light (laser) energy, radiofrequency energy, microwaves, or radioactive energy. Knowing the location of ...
