Abstract
A medical device for retracting tissue allows access to the inside of the body by “prying open” an existing or created opening in a body. The device comprises a substantially transparent head having first and second head halves defining a substantially conical surface including a gap when the first and second head halves are joined. Angular motion of the first and second head halves enlarges the existing or created opening and provides an area of access to the inside of the body. The substantially transparent nature of the device allows it to function as a light pipe so that the operator can see the body cavity or tract opened by the device. The device has scissors-like handles to allow an operator to open or close the device with one hand.
