Abstract

A minimally invasive surgery suction sleeve configured for use with an inner cannula of a suction instrument. The sleeve includes a first opening at a proximal end, a second opening at a distal end, and a tube between the first opening and the second opening. The sleeve slides over a suction instrument. The distal end is configured to insert into the body and includes a plurality of apertures that provide for pool suction. The sleeve further includes a flange at the proximal end that allows a surgeon to manipulate the sleeve, switching between spot and pool mode by sliding the sleeve over the inner cannula of the suction instrument. In spot mode, the tip of the suction instrument is exposed. In pool mode, the sleeve slides forward, covering the tip of the suction instrument so that fluent material is drawn through the apertures in the sleeve.

Claims

1. A sleeve for use with a minimally invasive surgery suction instrument, comprising:

a tube having an inner lumen configured to receive an inner cannula of the suction instrument and allow the inner cannula to translate freely within the inner lumen, wherein the tube comprises a first segment and a second segment joined by a connector, the connector comprising;

an outer connection member at the end of the first segment;

an inner connection member at an end of the second segment and configured to insert into the outer connection member; and

an O-ring seated within the outer connection member and configured to support the inner cannula of the suction instrument and form a seal between the inner cannula and the inner lumen;

a distal end of the tube configured to insert into an introducer port, the distal end having a plurality of radially facing apertures and an axially facing opening; and

a proximal end connected to the tube and configured to facilitate grasping and manipulation by a user to translate the sleeve between a first position exposing a distal tip of the inner cannula beyond the axially facing opening of the tube and a second position where the distal tip of the inner cannula is seated within the inner lumen of the tube, proximal to the radially facing apertures.

2. A sleeve for use with a minimally invasive surgery suction instrument, comprising:

a tube having an inner lumen configured to receive an inner cannula of the suction instrument and allow the inner cannula to translate freely within the inner lumen, wherein the tube comprises a first segment and a second segment joined by a connector, wherein the connector comprises a slip-fit connection;

a distal end of the tube configured to insert into an introducer port, the distal end having a plurality of radially facing apertures and an axially facing opening; and

a proximal end connected to the tube and configured to facilitate grasping and manipulation by a user to translate the sleeve between a first position exposing a distal tip of the inner cannula beyond the axially facing opening of the tube and a second position where the distal tip of the inner cannula is seated within the inner lumen of the tube, proximal to the radially facing apertures.

3. A sleeve for use with a minimally invasive surgery suction instrument, comprising:

a tube having an inner lumen configured to receive an inner cannula of the suction instrument and allow the inner cannula to translate freely within the inner lumen;

a distal end of the tube configured to insert into an introducer port, the distal end having a plurality of radially facing apertures and an axially facing opening;

a proximal end connected to the tube and configured to facilitate grasping and manipulation by a user to translate the sleeve between a first position exposing a distal tip of the inner cannula beyond the axially facing opening of the tube and a second position where the distal tip of the inner cannula is seated within the inner lumen of the tube, proximal to the radially facing apertures; and

at least one channel on an exterior of the distal end of the sleeve, the channel connected to at least one of the plurality of apertures.

4. The sleeve of claim 3, wherein the channel is configured to direct flow of fluent material to at least one of the plurality of radially facing apertures.

5. A method of providing suction during a surgical procedure, comprising:

providing a sleeve that slides onto an inner cannula of a suction instrument, the sleeve having;

a tube having an inner lumen configured to receive an inner cannula of the suction instrument and allow the inner cannula to translate freely within the inner lumen;

a distal end of the tube configured to insert into an introducer port, the distal end having a plurality of radially facing apertures and an axially facing opening, wherein the distal end of the sleeve includes a channel on an exterior of the distal end, the channel connected to at least one of the plurality of apertures; and

a proximal end configured to facilitate manipulation by a user;

sliding the sleeve onto the inner cannula of the suction instrument, where the inner cannula is disposed within the inner lumen of the sleeve;

inserting the distal end of the sleeve with the inner cannula through an introducer port into a body;

manipulating the proximal end of the sleeve to extend the radial apertures over a distal tip of the inner cannula to provide pool mode suction; and

manipulating the proximal end of the sleeve to extend the distal tip of the inner cannula beyond the distal end of the sleeve to transition to spot mode suction, where the transition between pool mode and spot mode occurs while the sleeve and suction instrument are seated within the introducer port.

6. The method of claim 5, further comprising directing fluent material to the at least one of the plurality of apertures via the channel.

7. A sleeve for use with a minimally invasive surgery suction instrument, comprising:

a tube configured to slide over an inner cannula of the suction instrument;

a distal end of the tube configured to insert into an introducer port, the distal end having a plurality of radially facing apertures and an axially facing opening;

a proximal end of the tube configured to facilitate grasping and manipulation by a user, the proximal end having a flange that extends radially from the proximal end, wherein pressure on the flange slides the sleeve to cover the inner cannula of the suction instrument;

a groove on an exterior of the distal end that directs flow of fluent material in the direction of at least one of the plurality of radially facing apertures; and

an O-ring seated within the tube, wherein the inner cannula is inserted through the O-ring and the O-ring forms a seal between the inner cannula and interior surface of the tube.

8. The sleeve of claim 7, the tube comprising a first segment, a second segment, and a connector that couples a first segment of the tube and a second segment of the tube.
