Abstract: An electrical pin field (200) includes a gasket (312), a support member (204) and a plurality of electrically conductive pins (202). The molded member has a main body (320) with a groove (310) formed therein. The groove is sized and shaped for receiving the gasket. The main body has a first and second retaining portion (316, 318) for retaining the gasket within the groove. The second retaining portion can have a chamfered edge (314) with a chamfered angle between fifteen and seventy degrees. The electrically conductive pins are integrated within the molded member.

Abstract: A cradle is provided for a handheld communications device (106). The cradle is comprised of a rigid structure (160), a latch actuator (302), a latch (300), an engagement face (514), and a resilient member (304, 304-1, 304-2). The rigid structure defines a compartment (202) for receiving the device. The compartment is comprised of an aperture and a sidewall structure (314). The latch actuator is comprised of a first end portion (716) and a second end portion (720). The latch actuator is movable in a sliding motion aligned with the sidewall between a first position and a second position. The latch is pivotally mounted to the first end portion of the latch actuator. The resilient member resiliently biases the latch actuator in a first position. The latch actuator is engaged when the device is inserted into the compartment and pushed down such that a force is applied to the latch actuator causing the latch to be moved to a second position where it engages the device.

Abstract: A manual control device for laparoscopic patient treatment by use of electrical curetage or coagulation, with means for clearing the surgical sight by irrigation or suction, finger operated buttons controlling the various functions, and an interlock mechanism disabling the electrical functions when a push button is depressed to enable irrigation or suction.

Abstract: An electrosurgical probe is provided which reduces the likelihood of arcing from the probe. In addition, the probe provides the ability to place a fiber-optic cable through the probe for providing for laser surgery or for laproscopic examination of the patient. The electrosurgical probe comprises an electrosurgical tip, a cylindrical body attached to the tip, and a base attached to the cylindrical body. The tip may have many different shapes but a spatula shape is generally preferred. The tip has at least one notch in the periphery of the spatula shape for retaining a fiber-optic cable. The cylindrical body is substantially hollow so that suction, irrigation, and laparoscopy may be carried out through the probe. To aid the surgeon in determining dimensions of organs within a patient, the cylindrical body has a plurality of striped regions having a predetermined thickness spaced apart at predetermined intervals on an outer surface of the cylindrical body.

Abstract: A simple and reliable electrosurgical instrument includes a cable having a main contact wire and first second insulated switch wires all provided with a short insulated or bare portion. The cable is received in a main member having a first holding mechanism for holding the switch wires adjacent uninsulated portions thereof on one lateral side and spaced from one another as well as a second holding mechanism for holding the switch wires adjacent the uninsulated portions thereof on the other lateral side so that the uninsulated portions span between the first and second holding mechanisms and are spaced longitudinally from one another. A blade receiver receives an electrode blade and is then electrically connected to the contact wire. A switch device selectively connects one of the uninsulated portions of the switch wires to the contact wire during operation. The first and second holding mechanisms preferably include channels and a cover includes projections which hold the wires in place.

Abstract: A cannula is provided for laparoscopic surgery wherein the cannula comprises a housing and elongated tube with a passageway formed within the housing so that laparoscopic instruments may be passed through the housing and the elongated hollow tube into the abdominal cavity of a patient. A pair of rollers are mounted within the housing, the rollers being spring-urged together to close the passageway through the housing when an instrument is withdrawn. A slidable plate having apertures of different sizes are mounted in the housing with the apertures provided with slitted seals therein to close the passageway through the housing. The varying sized apertures in the slidable plate permit laparoscopic instruments of varying diameters to be used and to maintain an effective seal around the instrument. In another embodiment of the cannula a valve is provided which is closed when the rollers within the housing are in engagement with each other.

Abstract: An intrinsically safe telephone system for use in mines or similar hazardous areas including a battery charging circuit arranged to supply charging current of a predetermined low value to the battery of an operational unit located in the hazardous area during on-hook periods. A circuit is provided for modulating the charging current below the predetermined value to generate both the incoming and outgoing call signals during signaling periods.
