Abstract
A surgical clamping device for hollow anatomical structures such as, essentially, blood vessels, but also for tracheas, intestines, etc. This device comprises a flexible guide and two jaws, each jaw being formed of an elongate member pierced with a longitudinal canal and having a distal end and a proximal end. These jaws can be slipped over the guide with their proximal end facing toward each of the ends of the guide. A mandrel is slipped over the two ends of the guide and brings the axes of the two jaws closer together, thus pinching the anatomical structure. This surgical clamping device applies more particularly to the clamping of the aorta.
Claims14
A surgical clamp which comprises
- a flexible guide having two ends;
- two jaws, each jaw being formed of an elongated member having an axis and pierced with a longitudinal canal and having a distal end and a proximal end, said jaws being designed so as to slip over the guide with their proximal end facing toward each of the ends of the guide;
- a mandrel configured to be slipped over the two ends of the guide and which is able to bring the axes of the two jaws closer together.
A method of clamping a blood vessel comprising the following operations:
- making a porthole in a warm-blooded organism,
- introducing a flexible guide into said porthole,
- causing a distal end of this guide to reemerge from the porthole, encircling the structure to be clamped,
- slipping over each of the ends of the flexible guide an elongate member equipped with a longitudinal canal, with a distal part and with a proximal part,
- bringing the distal ends of these two elongate members one onto each side of a blood vessel that is to be clamped,
- slipping a hollow mandrel over the proximal ends of these elongate members,
- causing the hollow mandrel to move toward the distal end of the elongate members, thus causing the elongate members to move closer together and to pinch the blood vessel.
