Abstract

A trocar sleeve capable of holding an endoscopic camera system and an associated endoscopic camera system are provided. When integrated with the trocar sleeve, the endoscopic camera can be used to provide a panoramic overview of the surgical area to supplement the view provided by a main endoscopic camera. The trocar sleeve includes a tube and a base coupled to the tube. The tube includes a channel for accommodating a surgical tool, such as a trocar. The tube further includes a receptacle separate from the channel, for allowing removable attachment of an endoscope to the trocar sleeve. The base includes a fastener for allowing removable attachment of an endoscopic camera head to the trocar sleeve. The camera head has a corresponding fastener for mating with the fastener of the base.

Claims

1. A trocar sleeve comprising:

tubular member;

a first channel formed by an inner surface of the tubular member to accommodate a surgical tool; and

a second channel, separate from the first channel, formed by an outer surface of the tubular member, to allow removable insertion of an endoscope into the trocar sleeve.

2. A trocar sleeve as recited in claim 1, further comprising a base coupled to an end of the tubular member.

3. A trocar sleeve as recited in claim 2, further comprising a continuation of second channel formed in an outer surface of the base, to allow removable insertion of the endoscope into the trocar sleeve.

4. A trocar sleeve as recited in claim 2, wherein the base includes a fastener configured to allow removable coupling of an endoscopic camera head to the base.

5. A trocar sleeve as recited in claim 1, wherein the second channel is defined lengthwise along the outer surface of the tubular member.

6. A trocar sleeve as recited in claim 1, wherein the endoscope is a rigid endoscope.

7. A trocar sleeve comprising:

a tubular member having an inner surface forming a channel to accommodate a surgical tool;

a groove, a first segment of which is defined lengthwise in an outer surface of the tubular member to allow removable insertion of a rigid endoscope into the tubular member, such that at least a portion of the rigid endoscope is disposed substantially parallel to the channel when inserted into the tubular member; and

a base coupled to the tubular member and having a second segment of the groove defined therein, to accommodate a portion of the rigid endoscope when the endoscope is inserted into the tubular member.

8. A trocar sleeve as recited in claim 7, wherein the base includes a fastener configured to allow removable coupling of an endoscopic camera head to the trocar sleeve.

9. An apparatus comprising:

a tubular member having a first end configured for insertion into the body of a patient, the tubular member further having an inner surface defining a channel for accommodating a surgical tool, the tubular member further having an outer surface with a groove defined lengthwise in the outer surface; and

a base coupled to a second end of the tubular member opposite the first end, the base including a fastener configured to allow removable attachment of an endoscopic camera head to the base, the base further having an outer surface with a continuation of said groove defined in the outer surface of the base, such that a rigid endoscope can be removably inserted into said groove.

10. A trocar sleeve comprising:

a tube having a first end configured to allow insertion into the body of a patient, the tube further having an inner surface defining a channel to accommodate an inserted trocar, the tube further having an outer surface with a groove defined lengthwise therein; and

a base coupled to a second end of the tube opposite the first end, the base including a fastener configured to allow removable attachment of an endoscopic camera head to the base, the base further having an outer surface with a continuation of said groove defined in the outer surface of the base, the groove configured to allow removable attachment of a rigid endoscope to the trocar sleeve, such that at least a portion of the rigid endoscope is disposed substantially parallel to the channel when inserted into the tubular member.

11. An endoscope comprising:

an input interface to receive light reflected from a body to be viewed;

an output interface to couple the endoscope to an endoscopic camera; and

a rigid elongate member to transmit light from the input interface to the output interface, the elongate member having at least one bend to conform the endoscope to a shape of a trocar sleeve.

12. An endoscope as recited in claim 11, such that the endoscope is removably insertable into a channel defined in an outer surface of the trocar sleeve.

13. An endoscope as recited in claim 11, wherein the at least one bend provides a total angular offset of approximately 90 degrees.

14. An endoscope comprising:

input interface to receive light;

an output interface to couple the endoscope to an endoscopic camera; and

a rigid elongate member to transmit light from the input interface to the output interface, the elongate member having at least one bend to conform the endoscope to a shape of a trocar sleeve, such that the endoscope can be removably inserted into a groove defined in an outer surface of the trocar sleeve.

15. An endoscope as recited in claim 14, wherein the at least one bend provides a total angular offset of approximately 90 degrees.
