Surgical port with embedded imaging device
First Claim
1. An endoscopic port assembly comprising:
- an endoscopic port including a lumen, a portion of the lumen including a tubular wall;
a trocar sized to be insertable into the lumen, wherein the trocar includes a shaft, there being a gap between the shaft and the tubular wall when the trocar is inserted into the lumen; and
an imaging device movably mounted to the tubular wall of the portion of the lumen, wherein the gap is sized to receive at least a portion of the imaging device, the trocar including a distal tip region connected to the shaft, the distal tip region being wider than the shaft such that, when the trocar is removed from the port, the distal tip region pushes the portion of the imaging device disposed within the gap such that the imaging device moves in a radially outward direction from the tubular wall.

Abstract
Disclosed is a disposable access port for use in endoscopic procedures, including laparoscopic procedures. The access port includes a cannula with an embedded camera in communication with an external control box. In operation, a trocar is combined with the access port to facilitate insertion of the access port into an anatomical site. Prior to insertion, the camera is pushed inside the cannula, where it remains during insertion. The trocar is removed after the access port has been inserted to allow surgical instruments to access the anatomical site. During removal of the trocar, a portion of the trocar urges the camera out of the cannula, thereby allowing visualization of the anatomical site. The camera can be fixedly or adjustably mounted on the port. A camera may also be mounted on the trocar. The trocar may include irrigation and suction channels to facilitate a clear view of the anatomical site.

19. An endoscopic port assembly comprising:
-
an endoscopic port including a proximal end, a distal end, an instrument passageway extending between the proximal and distal ends, and a first seal disposed within the passageway, a portion of the instrument passageway including a tubular wall, the first seal movable between an open position at which air may flow through the passageway and a closed position at which air flow through the passageway from the distal end to the proximal end is blocked; a trocar sized to be insertable into the instrument passageway, wherein the trocar includes a shaft, there being a gap between the shaft and the tubular wall when the trocar is inserted into the instrument passageway; and an imaging device movably mounted to the tubular wall of the portion of the instrument passageway, wherein the gap is sized to receive at least a portion of the imaging device, the trocar including a distal tip region connected to the shaft, the distal tip region being wider than the shaft such that, when the trocar is removed from the port, the distal tip region pushes the portion of the imaging device disposed within the gap such that the imaging device moves in a radially outward direction from the tubular wall. - View Dependent Claims (20, 21, 22, 23, 24)
