  • Patent number: 10512394
    Abstract: The present invention discloses a new and improved endoscopic-enabled mouth gag for routine ENT procedures, such as adenoidectomy and nasopharyngeal biopsy. The invention modifies the existing mouth gag, provides a stable and adjustable placement for an endoscopic device potentially employed during an ENT procedure, and is to replace the outdated surgical method where the surgical field is visualized indirectly via a handheld mirror (with or without the preexisting mouth gag). The inventive endoscopic-enabled mouth gag not only provides enhanced visualization of the surgical field for a clinician, assistants, and trainees, but also enables a clinician to perform the procedure bimanually (with both hands).

    Abstract: A vaginal speculum, conical in shape made out of clear plastic resin or metal that when closed can easily and gently be inserted into the introitus (vaginal opening). In certain embodiments, an obturator is used to introduce and/or expand the speculum. Various mechanisms are disclosed for dilating the speculum, after it has been inserted, so as to allow inspection of the patient's cervix. Such dilation can be effected relative to multiple axes, or even in substantially continuous, radial fashion about the periphery of the speculum, for improved visualization. In addition, this speculum has a handle that is oriented such that a vaginal exam can be performed on a standard exam table. The handle also includes a receptacle that receives a standard pen light. A light pipe directs light from the pen light to illuminate the cervix.

  • Patent number: 7150714
    Abstract: A minimally invasive retractor system is shown which has a support frame having two opposing pairs of horizontally oriented sides. The sides of the frame can be adjusted to vary an interior space of the frame. Four retractor blades are mounted on the frame for engaging tissue within a surgical site. Each retractor blade has an elongate body portion with a length which is oriented perpendicularly to the frame in use. One of the retractor blades can be equipped with a light source and a suction source which are integral to the blade. The blade also has an integral power source for powering the light source. The blade can also house a tissue retractor such as a dural retractor for retracting the dural sack of a patient during spinal surgery.

  • Patent number: 6595917
    Abstract: The disposable speculum with included light and complementary mechanisms for examination and gynecological surgery is a device used for medical and surgical procedures in the vagina, neck level and the uterus. It has two separate sheets joined in their own handles; the upper sheet has three cuts to evacuate the gases and smoke produced on the surgery area. It also has a light bulb to give clarity on the surgery area, to optimize the visibility with aluminum reflexive cover; the lower sheet has three cuts connected among themselves for an internal central channel, to evacuate the blood and fluids coming from the surgical area; the upper sheet's handle has some buttons to activate an opening and close mechanism of these sheets.

  • Patent number: 6589168
    Abstract: A charge-coupled device camera is removably mounted in a adaptor and the adaptor is removably mounted in the viewing aperture of a speculum. The camera is connected to a display device, such as a video monitor, by a cable. At least one high-intensity light is also mounted in the adaptor with the axis of the light parallel to that of the camera. The light is connected to an adjustable power source by a power supply cord. In one embodiment of the invention, a cervical positioner is provided to allow the physician to align the patient's cervix with the camera's axis for optimal viewing.

  • Patent number: 6569091
    Abstract: A vaginal speculum consists of two pivotally interconnected disconnectable parts. Each part slidingly supports a movable blade moveable in the longitudinal direction of the speculum. In addition to longitudinal movement, one of the blades can be moved circumferentially. Each blade can be completely withdrawn from the speculum, even during the procedure, i.e., without removing the speculum from the vagina. As a result, the same speculum can be used in procedures requiring both as well as only one blade. Furthermore, the entire upper part of the speculum, i.e., the guide portion together with the removable blade, can be completely disconnected from the speculum without removing the latter from the vagina. The remaining lower part can be used as a spatula. Circumferential displacement of one of the blades in both directions makes it possible to observe the vaginal cavity over the entire periphery without rotating the entire speculum or replacing it with another tool.

  • Publication number: 20020183595
    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.
