Abstract

The collection container has a reusable, autoclavable vessel with a resilient plastic reusable insert to which the aspiration instrument is connected. The insert incorporates a fluid passageway which may be blocked by squeezing action of a solenoid-type actuator. The insert includes a breakaway portion which is severed from the body of the insert during installation prior to use. This insert may also stay in place during autoclaving or cleaning.

Claims

1. A microsurgical cassette for use in a vacuum operated microsurgical system having an aspirating instrument, comprising:

said coupler member having an internal passageway extending and communicating between said first and second means;

at least a portion of said coupler member through which said passageway extends being made of a resilient and deformable plastic material, the deformation of said coupler portion being capable of closing said passageway and thereby controlling the flow of aspiration fluid; and

wherein one of said vessel walls defines a recess which extends below the plane of said one vessel wall and said coupler member has a top surface which lies generally flush with the plane of said one vessel wall, when said coupler member is fit within said recess.

2. The cassette of claim 1 wherein said vessel walls are made of autoclavable plastic material.

3. The cassette of claim 1 wherein said vessel walls are made of a polycarbonate material.

4. The cassette of claim 1 wherein said coupler member means is made of a silicone polymer.

5. The cassette of claim 1 wherein said coupler member means is formed to include a reflux chamber in said passageway.

6. The cassette of claim 1 wherein both said vacuum port and said aspiration port are disposed on the same one of said vessel walls.

7. The cassette of claim 1 wherein one of said vessel walls is a top wall and said vacuum port and said aspiration port are disposed on said top wall.

8. The cassette of claim 1 wherein said recess has a second wall portion which defines an opening for receiving said second means.

9. The cassette of claim 1 wherein said first and second means are disposed generally at right angles to one another.

10. The cassette of claim 1 wherein said second means includes an elongated end portion and an intermediate portion, said intermediate portion having structurally weakened breakaway means for severing said elongated end portion from the remainder of said second means.

11. The cassette of claim 1 wherein said second means includes at least one annular sealing means around the circumference thereof.

12. The cassette of claim 1 wherein said vessel walls include at least one pair of generally parallel and vertically disposed sidewalls of a light transmissive material.

13. The cassette of claim 12 wherein said vessel has three orthogonal average dimensions and said vertically disposed sidewalls are spaced apart a distance which defines the smallest of said three orthogonal average dimensions.

14. A microsurgical cassette for use in a vacuum operated microsurgical system having an aspirating instrument, comprising:

a plurality of interconnected vessel walls forming a fluid containment vessel having an interior;

an aspiration port disposed in a first wall portion and communicating between said wall portion and said vessel interior;

a vacuum port disposed in one of said vessel walls and communicating with said vessel interior for introducing a vacuum into said interior;

a coupler member having a first means for communicating with said aspiration port and having a second means for communicating with said aspirating instrument of said microsurgical system;

chamber means in the fluid containment vessel and float means movably located within the chamber means operative to rise in the chamber means toward the top of one of the vessel walls whenever fluid in the vessel reaches a predetermined level;

said coupler member having an internal passageway extending and communicating between said first and second means; and

at least a portion of said coupler member through which said passageway extends being made of a resilient and deformable plastic material, the deformation of said coupler member portion being capable of closig said passageway and thereby controlling the flow of aspiration fluid.

15. The cassette of claim 14 wherein the chamber means is integrally formed with said top vessel wall.

16. The cassette of claim 14 wherein said float means comprises a substantially spherical ball.

17. A microsurgical cassette for use in a vacuum operated microsurgical system having an aspirating instrument, comprising,

a plurality of interconnected vessel walls forming a fluid containment vessel having an interior;

one of said vessel walls defining a recess which has a first wall portion in common with said vessel interior;

an aspiration port disposed in said first wall portion and communicating between said recess and said vessel interior;

a vacuum port disposed in one of said vessel walls and communicating with said vessel interior for introducing a vacuum into said interior;

a coupler member means having an I-shaped body portion having first and second end portions of a size and shape to frictionally fit within said recess and having an elongated middle portion between said end portions of a transverse dimension less than the corresponding dimension of said recess, the middle portion thereby providing a means for manually grasping said coupler member means to remove it from said recess;

said coupler member means having a first means for communicating with said aspiration port and having a second means for communicating with said aspirating instrument of said microsurgical system;

said coupler means having an internal passageway extending and communicating between said first and second means;

at least a portion of said coupler means through which said passageway extends being made of a resilient and deformable plastic material, the deformation of said coupler means portion being capable of closing said passageway and thereby controlling the flow of aspiration fluid.

18. The cassette of claim 17 wherein said internal passageway extends longitudinally through said middle portion.

19. A microsurgical cassette for use in a vacuum operated microsurgical system having an aspirating instrument, comprising:

a plurality of interconnected vessel walls forming a fluid containment vessel having an interior;

one of said vessel walls defining a recess which has a first wall portion in common with said vessel interior;

an aspiration port disposed in said first wall portion and communicating between said recess and said vessel interior;

a vacuum port disposed in one of said vessel walls and communicating with said vessel interior for introducing a vacuum into said interior;

a coupler member means positioned in said recess such that said coupler member means fills less than the entire volume of said recess to thereby define at least one unfilled space for reaching with the fingertips to grasp and remove said coupler member means from said recess;

said coupler member means having a first means for communicating with said aspiration port and having a second means for communicating with said aspirating instrument of said microsurgical system;

said coupler means having an internal passageway extending and communicating between said first and second means;
