Problems solved by technology

[0003] Although helpful, these bootstrapping methods are far from optimal
There are two main problems directly related to biopsy: resolution is limited; and these imaging modalities cannot distinguish benign from malignant tissue in most cases
Not a preferred solution since each biopsy creates an incision and can lead to complications

Embodiment Construction

[0097] Such as Figure 2a and Figure 2b As shown, the elongated shaft 25 of the tip portion 23 of a biopsy device according to the present invention includes a lumen 36, which may include, for example, a conventional needle (such as a hollow metal needle) used in a biopsy procedure, where the material of the shaft 25 may be positioned. around the cavity.

[0098] The shaft 25 of the biopsy device comprises a distal end 34 which is arranged peripherally in the distal region of the shaft. The shaft 25 of the biopsy device further comprises a flat front surface 22 which may be arranged centrally with respect to the shaft 25 . Said flat front surface 32 may rest on a pin 31 arranged on the rod 25 . The pin 31 may be part of the rod (eg a protrusion of the rod) or a separate object connected to the rod.

[0099] A transducer element 27 for emitting and / or receiving ultrasound waves is arranged on the flat front surface 32 . The wires 39 of the transducer 27 can be embedded in...

Abstract

The invention relates to a biopsy device, particularly a biopsy device comprising a shaft with a transducer element for providing information about acoustic properties of a material to be analysed, a system of positioning a biopsy device and a method for positioning a biopsy device. The biopsy device may be adapted to take biopsies of different regions of the 5 human body for excluding or detecting abnormalities as cancerous lesions. The biopsy device may be used to measure acousticproperties of the material while inserting the tip portion of the biopsy device into the material to be analysed. The biopsy device may further allow measurement based on elastography.

Description

technical field [0001] The present invention relates generally to a biopsy device, in particular to a biopsy device for providing information about the acoustic properties of a substance to be analyzed, to a system for positioning a biopsy device and to a method for positioning a biopsy device . Background technique [0002] To properly diagnose cancer, a biopsy is usually done. This can be done via the lumen of the endoscope or via a biopsy needle. For example, needle biopsy is used to obtain biopsy material from the prostate via the rectum. To find the correct location for a biopsy, various imaging modalities are used, such as X-ray, MRI, and ultrasound. In the case of prostate cancer, the needle is guided in most cases by an ultrasound probe inserted into the rectum. [0003] Although helpful, these bootstrapping methods are far from optimal. There are two main problems directly related to biopsy: resolution is limited; and these imaging modalities cannot distinguish...
