Definitions
- the invention relates to a medico-surgical discharge cannula of the type comprising, in its axial part, a channel provided, at its distal end, with a drainage opening; at the periphery of its distal part, a plurality of drainage orifices opening into said channel; at its proximal end, a connector capable of connecting the cannula to a suction tube; said cannula being associated with a stylet-mandrel capable of being inserted therein to give it the rigidity necessary for its adequate positioning in the area to be drained.
- the depositor has designed a discharge cannula which is essentially characterized in that the peripheral drainage orifices open, outside the cannula, into the bottom of grooves made at the periphery of the distal part of said cannula.
- the grooves are in the form of a spiral;
- the distal end of the drainage channel is conical and tapering from inside to outside.
- FIG. 1 is a top view of the cannula according to the invention.
- - Figure 2 is a side view of said cannula;
- - Figure 3 is a view, in longitudinal section, of the distal part of the cannula;
- FIG. 4 is a partial sectional view of a drain for the drainage of intracavitary effused blood.
- the cannula shown in the figures essentially comprises:
- a connector (5) capable of connecting the cannula (1) to a suction tube.
- the cannula is associated with a stylet stylet capable of being inserted therein to give it the rigidity necessary for its adequate positioning in the heart.
- the drainage orifices (4) open, outside the cannula, into the bottom of grooves (6) produced at the periphery of the distal part of the cannula (1). This particular feature aims to avoid sticking of the vascular wall during aspiration.
- the grooves (6) can be made in the form of a spiral.
- the angle formed by the grooves (6) and the longitudinal generatrices of the cannula (1) is advantageously between 20 ° and 40 ° including 30 °. This particular feature aims to promote the evacuation of blood flow.
- the material used to make the distal part of the cannula (1) is shape memory such that, when the stylet-mandrel is introduced into the cannula (1), the grooves (6) are parallel to the longitudinal generatrices of said cannula and, when said stylet-mandrel is removed therefrom, the grooves regain their spiral shape.
- the distal end (3) of the channel (2) is conical and of decreasing section from the inside to the outside.
- the outer distal end (7) of the cannula is bevelled or rounded in order to allow better introduction thereof and a reduction traumatic areas crossed.
- the cannula can include:
- a first reference ring (8) indicating the position of the end of the cannula in the left atrium of the heart for example
- - A second reference ring (9) indicating the position of said end in the left ventricle of the heart for example.
- the cannula can be made of silicone or polyvinyl chloride depending on the flexibility and biocompatibility sought but also depending on the operating technique chosen by the surgeon.
- silicone or polyvinyl chloride depending on the flexibility and biocompatibility sought but also depending on the operating technique chosen by the surgeon.
- the cannula is 300 mm long, the first ring is located 70 mm from the distal end and the second 50 mm from the first in the proximal direction;
- the cannula has an outside diameter of 7 mm and the canal a diameter of 4 mm, the corresponding drainage opening having a diameter of 3 mm;
- the grooves, cylindrical fraction have a diameter of 2 mm and the corresponding orifices have a diameter of 1 mm;
- FIG. 4 represents more particularly a drain (10) for the drainage of intracavitary effused blood (in abdominal or muscular application) which also comprises grooves (6) and drainage orifices (4). It further comprises an enlarged area (11) in the shape of a warhead, and a removable holding device (12) on the body wall (13) passed through.
