International Classification:

A61B 1739

US Classification:

606 45

Abstract:

A vacuum hood attachment for electrosurgical instruments has a hollow tubular body open at each end and a side opening for connection to a source of vacuum. One of said end openings is to be fitted on the end of an electrosurgical instrument of a pencil- or pen-like or other hand held construction having an electrocauterizing or electrocutting blade secured therein. The other open end of said tubular body surrounds the blade along part of the length thereof. On connection to a source of vacuum during use, the hood attachment withdraws vapors and smoke from an operating site to keep the same clear for observation by the surgeon. This hood attachment fits a variety of shapes of electrosurgical instruments and may fit around the end of the instrument and/or into a recess in the end of the instrument depending on the construction of the instrument. The hood attachment may be secured by friction fit or clamped, wedged or cemented into place. Depending on the design of the electrosurgical instrument, the hood attachment may be cylindrical in shape or may be tapered or may have a portion to be fitted into a recess on the instrument.

Gerald W. Johnson - Houston TX

International Classification:

A61M 100

US Classification:

604 35

Abstract:

A fat collection syringe is shown which has a barrel with an open end and a closed end with nipples for connection respectively to a source of high suction vacuum and to a collection needle. A plunger is longitudinally movable in the barrel to facilitate receiving collected material and has a longitudinal central passage for connection to a low suction vacuum for drawing a washing liquid through the material collected therein. The plunger central passage extends from end to end and has a scraper mounted on its inner end wall. A suction tube extends through the passage with a filter on its inner end and is positioned in engagement with the scraper. The outer end of the tube has a cap positioned thereon when vacuum is being applied to the nipple connected to high suction vacuum. The cap is removable from the suction tube to permit the tube to be connected to a low suction vacuum and the other nipple to be connected to a source of washing liquid to draw such liquid through fatty material collected in then barrel. The suction tube is rotatable to move the filter along the scraper to remove contaminants from collected material while washing the same with washing liquid.

International Classification:

A61B 1736

US Classification:

606 37

Abstract:

An electrosurgical apparatus comprises an electrosurgical generator for producing cutting and coagulation signals and has either pedal operated or hand operated switches for switching on and off and between cutting and coagulation signals. A cutting and coagulation probe is energized by the generator and has a handle portion and a probe element. An on/off switch controls energization of the probe element. A switch is operated to switch the probe element between the cutting current and coagulation current. A holder member removably supports the probe element and has an electric socket therein. The probe element is removably supported in the holder member and has an electric connector cooperable with the holder member socket to complete an electric connection to the probe element. An electric connector connects the probe element to the electrosurgical generator circuit. The on/off switch may be in the holder element or in a pedal operated switch.

Appl. No.:

Inventors:

Gerald W. Johnson - Houston TX

International Classification:

A61M 532

US Classification:

604198

Abstract:

A hypodermic needle has a retractable tubular sheath slidably mounted on its forward end and movable relative thereto between a rearward retracted position exposing the front end of the needle and a forward protective position enclosing the front end of the needle. In one embodiment, a spring within the sheath urges the sheath to the forward protective position enclosing the front end of the needle. The rear of the sheath cooperates with pins on the needle to engage them upon relative rotation in one direction to allow rotation as a single unit to connect the needle to fluid ejection or withdrawal members. Relative rotation in the opposite direction disengages the pins allowing the sheath to be moved rearward causing the front end of the needle to protrude beyond the front end of the sheath and to lock the needle and sheath together upon further relative rotation in the opposite direction to disconnect and dispose of the needle without inadvertent injury by contact with the needle. Another embodiment has protrusions on the needle and a retractable sheath slidably mounted on the needle and movable between a rearward retracted position exposing the needle front end and a forward protective position engaging the protrusions and covering the front end of the needle. A further modification has a tubular catheter slidably received on the needle for hypodermic penetration therewith which is removably connected to the sheath whereby when the sheath and needle are removed from the catheter only the catheter remains in place.

International Classification:

US Classification:

604319

Abstract:

A vacuum apparatus for surgical aspirators comprises a motor and vacuum pump on a supporting base with an evacuated chamber surrounding them to reduce noise produced by the apparatus. The apparatus preferably comprises first and second hollow housings of one or more wall members defining an enclosure surrounding the motor and pump, the wall members of said housings spaced apart to define a vacuum chamber around the motor and vacuum pump. The enclosure has an opening to surrounding atmosphere through the supporting base or through a sealed opening through the housings. The pump outlet communicates with surrounding atmosphere. A passageway connects the vacuum chamber both to the vacuum pump inlet and the exterior of the apparatus. Operation of said motor and pump is effective to withdraw air from the chamber to produce a vacuum therein supplied for use through the passageway, the vacuum is the reservoir being sufficient for use over a period of time and providing sound insulation against noise produced by the apparatus. The apparatus has pressure responsive valves for (1) preventing flow of air into the vacuum chamber when the surgical cannula is removed, (2) closing off the vacuum chamber from the surgical cannula when the vacuum is insufficient and causing the vacuum pump to work directly on the surgical cannula, and (3) shutting down the motor when the vacuum reaches a selected level.

Inventors:

Gerald W. Johnson - Houston TX

International Classification:

A61M 2700

US Classification:

604268

Abstract:

A surgical instrument for use in suction lipolysis consists of a long, narrow tube having a pointed or tapered closed end, for insertion into the body, and being open at the other end for connection to a source of vacuum. The tube has a side opening adjacent to the closed end for entry of fatty material during use. A passageway is provided, either as a separate passage inside the tube or a separate tube inside or outside the main tube, with an end opening inside the closed end of the main tube beyond the side opening. A handle surrounds and supports the main tube and passageway and includes a manually operated valve for venting the other end of the passageway or separate tube to allow air to enter the closed end portion of the main tube during use for clearing obstruction therein.
