Blood vessel detection device
First Claim
1. A blood-vessel detection device for detecting the presence or absence of blood vessels underneath the tissue surface, the blood-vessel detection device comprising:
- a partially-deforming device which can be inserted into the body cavity so as to be in contact with the tissue surface in order to deform a part of the tissue surface, thereby generating turbulence in blood passing through blood vessels extending underneath the tissue surface;
a converting device for converting turbulent sound due to the turbulence generated in a part of the tissue surface deformed by the partially-deforming device; and
a signal processing device for performing signal processing including at least amplification for the electric signals.

Abstract
A blood-vessel detecting device includes a partially-deforming device which can be inserted into the body cavity so as to come into contact with the tissue surface in order to deform a part of the tissue surface so that turbulence is generated in a blood flow within blood vessels extending underneath the tissue surface, thereby enabling detection of the presence or absence of blood vessels underneath the tissue surface. Turbulent sound due to the turbulence generated at a part of the tissue surface deformed by the partially-deforming device is converted into electric signals by a converting device, following which the electric signals are subjected to signal processing such as amplification and so forth by a signal processing device.

26. A blood-vessel detection device for detecting the presence or absence of blood vessels underneath the tissue surface comprising:
-
an endoscope including an inserting portion for being inserted into the body cavity;
a partially-deforming device which is inserted into a channel of the endoscope, or is mounted onto the tip of the inserting portion thereof, for deforming a part of the surface of the tissue within the body cavity in order to generate turbulence in a blood flow passing through blood vessels extending underneath the tissue;
a turbulent-sound sensor for detecting turbulent sound due to the turbulence; and
a signal processing device for performing signal processing for notifying the surgeon of the presence or absence of turbulent sound, or for displaying such information, based upon the electric signals detected by the turbulent-sound sensor. - View Dependent Claims (27, 28)
