Abstract

An instrument port for introducing instruments into a surgical site, including a port body having a channel running therethrough from a proximal end to a distal end, an instrument sleeve in slidable contact with the channel, creating a gap therebetween, and fluid flow for removing emboli efficiently from the instrument port, wherein the fluid flow includes the gap is provided. A fluid flow system for use in an instrument port is provided. A method of removably securing an instrument sleeve to a port body by anchoring the instrument port to heart tissue, making at least one flood line in a channel, flushing out emboli, and performing surgery with the instrument port.

First claim

1 . (canceled)

2 . An instrument port for introducing an instrument into a surgical site, the instrument port comprising:
a port body including a body channel extending therethrough from a proximal end to a distal end of the port body, wherein the body channel is configured to receive the instrument; a transparent bulb at the distal end of the port body; and an imaging system at the distal end of the port body within the transparent bulb, wherein the imaging system comprises an imaging device and an illumination device.

3 . The instrument port of claim 2 , wherein the imaging device comprises an infrared imaging device.

4 . The instrument port of claim 2 , wherein the transparent bulb is configured to provide a clear imaging medium.

5 . The instrument port of claim 2 , wherein the imaging system is positioned on the distal end of the port body such that the surgical site can be imaged.

6 . The instrument port of claim 2 , wherein the illumination device comprises a fiber optic illumination device.

7 . The instrument port of claim 2 , wherein the illumination device is positioned on the distal end of the port body such that the surgical site can be illuminated when the instrument is inserted into the surgical site.

8 . The instrument port of claim 2 , further comprising:
a fluid inlet at the proximal end of the port body and in fluid communication with the body channel, the fluid inlet configured to receive fluid from a fluid source; and a fluid outlet at the proximal end of the port body and in fluid communication with the body channel, the fluid outlet configured to be connected to a suction source.

9 . The instrument port of claim 8 , wherein the fluid outlet is configured to be in fluid communication with an instrument channel extending through the instrument when the instrument is inserted into the body channel.

10 . The instrument port of claim 9 , wherein application of suction to the fluid outlet causes fluid to be drawn into the fluid inlet from a fluid source, through the body channel between an outer surface of the instrument and an inner wall of the body channel, into a proximal end of the instrument channel, through the instrument channel towards the distal end of the instrument channel, and out through the fluid outlet.

11 . The instrument port of claim 8 , wherein the fluid outlet is configured to be in fluid communication with an interface between the instrument and an instrument sleeve, wherein the instrument sleeve is configured to be slidably inserted into the body channel and configured to receive the instrument.

12 . The instrument port of claim 11 , wherein application of suction to the fluid outlet causes fluid to be drawn into the fluid inlet from a fluid source, through the body channel between an outer surface of the instrument sleeve and an inner wall of the body channel, into an inlet at a distal end of the instrument sleeve, through the instrument sleeve between an outer surface of the instrument and an inner wall of the instrument sleeve, and out through the fluid outlet.

13 . The instrument port of claim 2 , further comprising an openable seal disposed at the distal end of the port body.

14 . The instrument port of claim 13 , wherein the openable seal is configured to be opened when a positive pressure is exerted on the openable seal.

15 . The instrument port of claim 13 , wherein the openable seal is configured to allow a distal end of the instrument to open the seal and protrude through the distal end of the port body.

16 . A method for introducing an instrument into a surgical site, the method comprising:
inserting the instrument into a body channel of a port body, wherein the body channel extends through the port body from a proximal end of the port body to a distal end of the port body, wherein the body channel is configured to receive the instrument; and operating an imaging system at the distal end of the port body to obtain an image of the surgical site, wherein the imaging system is disposed within a transparent bulb at the end of the port body, and wherein the imaging system comprises an imaging device and an illumination device.

17 . The method of claim 16 , wherein the illumination device comprises a fiber optical device.

18 . The method of claim 16 , wherein the imaging device comprises an infrared imaging device.

19 . The method of claim 16 , further comprising applying suction to a fluid outlet at the proximal end of the port body to remove emboli from the body channel,
wherein application of suction to the fluid outlet causes fluid to be drawn into a fluid inlet at the proximal end of the port body, through the body channel between an outer surface of the instrument and an inner wall of the body channel to the distal end of the port body, into a distal end of an instrument channel extending through the instrument, through the instrument channel to a proximal end of the instrument channel, and out through the fluid outlet.

20 . The method of claim 19 , wherein applying suction comprises applying suction when an openable seal at the distal end of the port body is closed.

21 . The method of claim 16 , further comprising applying suction to a fluid outlet at the proximal end of the port body to remove emboli from the body channel,
wherein application of suction to the fluid outlet causes fluid to be drawn into a fluid inlet at the proximal end of the port body, through the body channel between an outer surface of an instrument sleeve and an inner wall of the body channel, into an inlet at a distal end of the instrument sleeve, through the instrument sleeve between an outer surface of the instrument and an inner wall of the instrument sleeve, and out through the fluid outlet, wherein the instrument sleeve is configured to be slidably inserted into the body channel and configured to receive the instrument.
