Abstract

The endoscope treatment tool (1) of the present invention is provided with: an elongated insertion part (15) inserted into the living body after passing through the treatment tool channel (10) of the endoscope (2); A tubular puncture needle (16) that penetrates the front end of the biological tissue; a tissue collection means (18) that collects the biological tissue while the puncture needle (16) is pierced into the biological tissue; and Collection means (18) Tissue processing means (22) for processing the collected biological tissue for analysis.

Description

technical field [0001] The present invention relates to a treatment tool for an endoscope, a biological tissue analysis and processing system, and a sample collection method for tissue analysis and treatment, which are inserted into a living body through a treatment tool channel of the endoscope and used in combination with the endoscope. Background technique [0002] Biological tissues within living organisms are typically harvested for biomolecular analysis. For the analysis of such biological tissue, for example, an instrument disclosed in JP-A-2001-275947 (Patent Document 1) has been used. Among them, a puncture needle for an endoscope inserted into a living body after passing through a treatment tool channel of an endoscope that observes the living body is used. The puncture needle for an endoscope is inserted into a living body under observation by an endoscope, and punctures a target biological tissue while puncturing it to collect the biological tissue. The biologi...
