A vaginal speculum and side wall retractor allows clinicians to visualize the cervix and upper vagina by retracting vaginal walls simultaneously. This device is comprised of a handle, a mobile introducer allowing the device to comfortably be inserted vaginally, and a lower blade capable of stabilizing the cervix and a body containing the side wall retractor. This retractor is comprised of a rolled-up sheet of transparent plastic which can be opened through a rotating shaft countersunk in the body of the base. A friction or sprocket gear allows the rotating shaft to open and close the plastic side wall retractor as well as completely unwinding the transparent plastic sheet so that the device can be removed while leaving surgical instruments in the vagina. The rotating shaft serves as a light guide and brings light from the knob, which contains an LED, into the rolled-up sheet during examinations.

A battery pack having a battery module and a cooling plate are provided. The battery pack has a bottom surface and a first plane that extends through the battery module parallel to the bottom surface. The cooling plate has a bottom pan and a top plate that are coupled together and extend along a longitudinal axis. The bottom surface of the battery module is disposed on the top plate. The bottom pan has a first cooling region with first and second flow path patterns therein that receive a refrigerant therethrough. The first and second flow path pattern are shaped and sized to maintain a temperature of first and second halves, respectively, of a cross-sectional area of the battery module within one degree Celsius of a first temperature level.
