Abstract
Abstract A retractor device for simultaneously retracting and viewing bodily tissues during a medical procedure. The retractor includes a blade member for retracting bodily tissues and an imaging device to form an image of the bodily tissues which are exposed by the operation of the blade member. The imaging device is coupled to a display device so that the image of the bodily tissues formed by the imaging device is displayed by the display device. Moreover, a method is provided for endoscopically performing a tissue retracting procedure using a retractor device. The method includes the steps of retracting bodily tissues using a retractor to form a cavity and imaging the cavity using an imaging device mounted on said retractor to form an image of the cavity and to provide the image of the cavity to a display device that is coupled to the imaging device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A device for endoscopically performing a tissue retracting procedure, said device comprising: a retractor having a handle connected to a shaft that is connected to a blade that is insertable into a body cavity to retract tissue; a hollow portion formed as part of said retractor; an endoscope dimensioned to fit securely within said hollow portion, said endoscope including capture means for capturing images of tissue being retracted and signal means for producing a signal corresponding to the captured images; and a remote display device connected to said signal means for displaying the captured images based on said signal.
Claim 2
Independent Claim
99 words
A device for endoscopically performing a tissue retracting procedure, said device comprising: a retractor having a handle connected to a shaft that is connected to a blade that is insertable into a body cavity to retract tissue; a hollow portion formed as part of said retractor; an endoscope dimensioned to fit securely within said hollow portion, said endoscope including capture means for capturing images of tissue being retracted and signal means for producing a signal corresponding to the captured images; and a remote display device connected to said signal means for displaying the captured images based on said signal.
Claim 3
Dependent Claim
41 words
The device as claimed in claim 1, further comprising a knob connected to said endoscope and located adjacent said handle of said retractor, to adjustably control a movement of said endoscope through a plurality of viewing angles within with body cavity.
Claim 4
Dependent Claim
35 words
The device as claimed in claim 1, further comprising a suction tube connected to said blade, said shaft and said handle, to evacuate smoke produced by an electrocautery device and accumulated in the body cavity.
Claim 5
Dependent Claim
21 words
The retractor device according to claim 1, wherein said signal means and said remote display device are coupled via a cable.
Claim 6
Dependent Claim
23 words
The retractor device according to claim 1, wherein said signal means and said remote display device are coupled via a wireless transmission system.
Claim 7
Dependent Claim
68 words
The retractor device according to claim 5, wherein said wireless transmission system includes a transmitter for transmitting signals containing image information related to said catured image, said transmitter being mounted on said retractor device, said wireless transmission system further including a receiver coupled to said remote display device for receiving said signals and processing said signals so that said image information is displayed by said remote display device.
Claim 8
Dependent Claim
23 words
The retractor device according to claim 1, wherein said captured image is digitally processed prior to being displayed by said remote display device.
Claim 9
Independent Claim
72 words
A method for simultaneously retracting and viewing bodily tissues during a medical procedure, the method comprising the following steps: retracting bodily tissues using a retractor having a blade member to form a cavity; imaging said cavity using an imaging device mounted on said retractor to an image of said cavity, said imaging device being coupled to a display device so that said image of said cavity is displayed by said display device.
Claim 10
Independent Claim
72 words
A method for simultaneously retracting and viewing bodily tissues during a medical procedure, the method comprising the following steps: retracting bodily tissues using a retractor having a blade member to form a cavity; imaging said cavity using an imaging device mounted on said retractor to an image of said cavity, said imaging device being coupled to a display device so that said image of said cavity is displayed by said display device.
