Instrument for tracheostomy and practice of intrathoracic

摘要

1. Instrument for practice of intrathoracic percutaneous tracheostomy and the type of dissection and can be introduced by a flexible guidewire and comprising two parts (1 and 2) related by their intermediate zone by a common pivot axis (3) allows to join the rear ends of said parts (1 and 2) to set the open position of the instrument, defining the rear ends of said parts a handle (5) gripping and front ends a point (4) curved, conical and an inner passage defined by half-carcasses (5) of complementary shape on the inner facing sides of respective parts (1 and 2), characterized in that both front ends, conforming the curved tip (4) have an anterior recess (8) concave by outside of the curvature, forming a rear projection (9) of convex contour, defined from the orifice (7) of the inner passage outlet, as a stop end disect or of the tip (4) when inserted instrument, avoiding contact of said end dissector against the posterior wall of the trachea; and because the outer sides of both sides of the tip (4) are bent so that, in the operating position opening the instrument, are parallel substantially maintaining the separation distance.
