  • Patent number: 9986903
    Abstract: Medical instruments, particularly structurally-adjustable speculums and retractors for obstetrical and gynecological operations, procedures, and examinations, including a minimally obstructive compact speculum or retractor. The compact speculum may comprise a first wing and a second wing; and a hinge comprising at least one hinge component. The compact speculum may further comprise a ratchet that releasably holds the wings in an open position. The hinge component may comprise the ratchet, an illumination source, a fluid handler, a light guide, a lubrication source, or a combination thereof. The compact speculum may be a vaginal speculum.

  • Patent number: 9907544
    Abstract: This application presents minimally-obstructive and structurally-adjustable retractors for vaginal repairs, which afford an open work area of desirable size and enhanced visualization for a surgeon about the perineum and the posterior vaginal wall of the patient. The retractors may be lightweight and compact, and also configured and dimensioned to minimize slippage during use. The retractors may have occluders that may partially or substantially block or absorb fluids, for example, from or around the cervix. The retractors may incorporate built-in light sources. The retractors may retract the engorged labia of the postpartum patient as well as the vaginal walls. The retractor may also be used as a speculum.

  • Patent number: 9861349
    Abstract: This application presents structurally-adjustable vaginal specula, which provides visualization and access to the vagina and the cervix. The specula may be lightweight and compact, and may also be configured and dimensioned to minimize slippage during use. The specula may comprise built-in light sources. The specula may comprise a fluid handler, for example, to remove fluids from the vagina during medical interventions. The specula may retract the labia as well as the vaginal walls. The speculum may also be used as a retractor.

  • Patent number: 9216029
    Abstract: This application presents a bifurcated, optimally-angled surgical forceps. In one example, this surgical forceps may enable a more natural maneuver for initial clamping of the vas deferens through the scrotal skin. This may be more comfortable for users and easier to maintain, and may provide greater tactile surface contact between the thumb and vas deferens. This device also may provide the surgeon with an entire segment of vas deferens upon which the vasectomy may be performed, thus reducing the need for frequent repositioning of instruments. The device may also be applied to other surgical procedures that may benefit from the features of the device and where a section of a tubular anatomical structure may need clamping at two points along its length. Examples include blood and lymphatic vessels, ducts of the digestive system, and large nerves or nerve bundles.

  • Patent number: 8985118
    Abstract: This application presents retention devices that afford the user quick and easy placement. These retention devices may accommodate objects of various shapes and sizes. The device provides sturdy means for retaining and securing an object to a surface without the need to handle and position flaps of tape. The device allows easy removal from the retained object without adhesives directly contacting or damaging it sensitive surfaces. The retention described here may be used to quickly secure anatomic structures during operations, such as securing the penis against the abdomen during vasectomy, without causing discomfort or damage to sensitive skin during application or removal.
