摘要

abstract "provision introduced in a medical instrument for the measurement of enlarged anastomosis or gastrojejunal stenosis by upper digestive endoscopy". it is a medical instrument (10) of the type used to measure enlarged anastomosis (an) or gastrojejunal stenosis (in) in order to assist the professional in deciding the appropriate treatment; said instrument (10) comes in the form of a flexible guide wire (11) with a diameter (d1) idealized for passing through the channel (c) with an internal diameter (d2) of 2.8 mm from conventional endoscopes (ed), and said guide wire (11) comprises the main body (11a) made of steel provided with a coating (12) made of polytetrafluoroethylene - ptfe; one of the distal ends (11b) of the body (11a) is formed by a hydrophilic portion (20); said hydrophilic portion (20) is black in color with a length (x) of 50 mm and makes up the measuring tip (mp) ideal for measuring the enlarged diameter (d3) of the anastomosis (an) or reduced diameter (d4) stenosis (en); said measurement point (pf) is formed by multiple marks (30) equidistant and that makes up a graduation (gd) for the measurement of diameters (d3) and (d4), in turn, measurement performed through upper digestive endoscopy by positioning of the measuring tip (mp) on the anastomosis (an) or stenosis (en). 1/1
