    Abstract: An ophthalmic marking device is provided herein for marking a patient's eye. The device may include a handle and a tip with a tip element, a first portion of the tip element protruding from the tip to be exposed. The tip element is electrically conductive to resistively generate heat with electrical flow therethrough. A source of electrical power is associated with the device and electrically coupled to the tip element. The source of the electrical power and the tip element are configured to cause the first portion of the tip element to have a temperature in a range of 250° F.-450° F. Advantageously, the subject invention provides for a relatively low-cost device for marking a patient's eye and allows for creating a less traumatic marking on a patient's eye as compared to higher temperature electrocautery devices.

  • Patent number: 9604375
    Abstract: A blade cartridge for a shaving razor contains a series of parallel blades and at least two contact segments as part of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. A radiator effect is created wherein heat produced by the contact segments passes between the blades towards the cutting edge of the blades. The combination of the heat produced by the electric current flow through the conductive blades and the heat produced by the contact segments provides a dual heat process that makes it easier to adjust and control the temperature to a desired stable heat temperature. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade.

  • Patent number: 6898997
    Abstract: An apparatus for stripping an insulated wire includes a resistive heater element having a first end, a second end, and a coil formed between the first end and the second end. The coil has an inner diameter that is large enough to receive a section of the insulated wire. The apparatus further includes an electronic circuit connected to the first and second ends to deliver power to the resistive heater element such that the coil uniformly distributes heat about the section of the insulated wire to thermally decompose insulation on the section of insulated wire.

  • Patent number: 6860880
    Abstract: An instrument and method are provided for sealing and joining or hemostatically dividing tissue, which is particularly suitable for laparoscopic and endoscopic surgery. The instrument makes use of the controlled application of a combination of heat and pressure to seal adjacent tissues, to join adjacent tissues, or to anastomose tissues, whereby tissue is heated for an optimal time and at an optimal temperature under optimal pressure to maximize tissue seal strength while minimizing collateral tissue damage. The instrument of the present invention is lightweight and therefore portable, and is particularly useful in field conditions where a source of external power may not be readily available.

  • Patent number: 6692692
    Abstract: The present invention involves a sterilization system for running high amperage current through a dental or medical handpiece to be sterilized thereby heating the handpiece to a point of sterilization. The system includes a controller, a high amperage current source, and a handpiece receptacle. The handpiece receptacle includes clamps to hold the handpiece in place and a temperature sensor to measure the temperature of the handpiece. The controller controls the amount of current supplied by the high amperage current source to the handpiece according to the temperature of the handpiece. After the handpiece has been at or above the sterilization temperature for the required period of time, the controller stops the flow of current to the handpiece.

  • Patent number: 6683280
    Abstract: The present invention is directed toward an improved method and apparatus for securing a prosthesis that is being implanted in a patient. A heat-curable bone cement is used to secure the implanted prosthesis in the patient. A heater is then applied to the prosthesis to decrease the time required for the cement in contact with the prosthesis to cure or set. An adjustable heater control and temperature gauge are used to monitor and control the amount of heat applied to the prosthesis. A socket is provided on the heater such that a tip designed to couple with the particular type of prosthesis being implanted in the patient can be installed on the heater. One or more safety gauges are used to monitor the heater's operation to insure that an excessive amount of heat is not being applied.

  • Patent number: 6652175
    Abstract: A structure of a heating nozzle for a glue gun includes a nozzle, a rubber ring and a rubber tubular member, the nozzle being provided with two heaters formed by a heat resistant and highly heat efficient element and assembled with the rubber ring and the rubber tubular member to form a nozzle assembly, wherein by means of connection in series and parallel with a battery chamber, a control switch and a LED indicator, the nozzle assembly is supplied with a 6-volt DC power source or externally connected with an AC power source or a power adapter to make the nozzle to melt a glue rod for proceeding with adhesion operation, whereby the length of the heating nozzle is decreased and can be pre-heated within a very short time and the nozzle is compact in size, the heating efficiency is high and power consumption is small, and the glue can be cooled rapidly, so as to avoid melting glue flowing out of the glue gun when the glue gun is turned off, and a direct heating method is used to melt the glue.

  • Patent number: 6482200
    Abstract: A battery operated, hand-held cautery apparatus including a cauterizing unit with a cautery body and a heating assembly having a heating element, a switch assembly, and a housing assembly is disclosed. The switch assembly is essentially the position of a battery. That is, the battery acts as a switch. Power is not supplied to the heating element when the battery is in a first position, but power is supplied to the heating element when the battery is moved to a second position. The housing assembly may include a biasing member in contact with the battery such that the biasing force of the biasing member must be overcome to move the battery from the first position to the second position and thus energize the heating element.

  • Patent number: 6335515
    Abstract: An electric heat sealer that has a main body having a longitudinal axis, and a sealing mechanism having a center point. The center point of the sealing mechanism is offset from the longitudinal axis. The electric heat sealer is used for sealing workpieces such as plastic bags or the like and also includes a casing defining a battery chamber and a press bar pivotally connected to the casing. The sealing mechanism is supported on a compression spring in a spring holder inside the casing, and a safety device.
