A flexible microsurgical instrument (10) having a distal portion (36) which is ground to a reduced diameter and covered with a stiffening sleeve (38) is disclosed. The instrument includes a proximal actuating handle (12) coupled to a flexible coil (14) containing at least one control wire (20 or 22) and a distal end effector (18) coupled to the distal end of the coil and a control wire. A distal portion of the coil is ground to a reduced outer diameter and thus a reduced thickness. The stiffness of the distal portion is enhanced by placing a stiffening sleeve (38) over the ground distal portion. The stiffening sleeve has a thickness substantially equal to one half the difference between the reduced diameter of the ground distal portion and the diameter of the remainder of the coil so that the outer diameter of the coil is substantially constant along its length when the stiffening sleeve is in place.

Un instrument microchirurgical flexible (10) possède une partie distale (36) qui est rectifiée jusqu'à obtention d'un diamètre réduit et recouverte d'un manchon de renforcement (38). L'instrument comprend une poignée d'actionnement proximale (12), raccordée à un enroulement flexible (14) contenant au moins un fil de manoeuvre (20 ou 22) et un organe terminal distal (18) raccordé à l'extrémité distale de l'enroulement et du fil de manoeuvre. Une partie distale de l'enroulement est rectifiée jusqu'à obtention d'un diamètre externe réduit et, par conséquent, d'une épaisseur réduite. On augmente l'épaisseur de la partie distale en plaçant un manchon de renforcement (38) sur la partie distale rectifiée. Le manchon de renforcement a une épaisseur sensiblement égale à une moitié de la différence entre le diamètre réduit de la partie distale rectifiée et le diamètre du restant de l'enroulement de sorte que le diamètre externe de l'enroulement soit sensiblement constant sur sa longueur lorsque le manchon de renforcement est en place.
