Description

HAND-HELD PORTABLE LASER SURGICAL DEVICE by ALEXANDRE B. Dl SESSA and MIHAI I. A. BOITOR
BACKGROUND OF THE INVENTION
This invention relates to portable laser surgical instruments. More particularly, the invention relates to an improved, hand-held laser surgical device combining at least one diode laser, power supply, and replaceable, disposable sterile tip with protective sleeve contained within a pen sized unit, particularly adaptable to oral surgery.
BRIEF SUMMARY OF THE INVENTION
Medical laser treatment using hand-held instruments has generally been developed for ophthalmic, dental, orthopedic, and similar surgical procedures where the treatment area is confined or particularly difficult to reach. Typically, a laser beam is transmitted from a laser source though an optical fiber to a treatment site. The optical fiber terminates proximally in a laser source connector for connection to the laser source and terminates distally in a hand-piece manipulated by the surgeon.
The diode laser has been in use for medical and dental purposes. Specifically, in the area of dental use, the diode lasers on the market have been reduced in size to approximately that of a shoe box. The dental laser unit has typically been connected to the delivery or surgical device in the form of a hand-piece using an optical fiber. Laser surgical devices provide certain advantages over traditional implements such as irradiation to vaporize the tissue and small blood vessels proximate thereto. Accordingly, laser surgical devices provide operations performed without hemorrhaging. Thus, the underlying conditions requiring blood transfusions to patients vanishes. Bloodless surgery also has the effect of preventing disease, which can be disseminated by transfusions or infections at the surgical site. These advantages are particularly useful for oral and dental surgical procedures, such as troughing, implant exposure, restoration, or pyogenic granuloma.
Another important advantage of medical laser devices is that small lymphatic vessels in tissues are sealed by the irradiation of the laser beams. This feature greatly reduces occurrence of edema caused by accumulation of lymph after surgery, and likewise prevents spreading of cancerous cells during surgery or thereafter.
Laser surgery often reduces post-surgical pain by sealing nerve ends cut at the operational target site.
Post-operative scar tissue is reduced by use of medical laser devices. Accordingly, the incidence of post-surgical stricture is reduced, thus minimizing a major cause of re-surgery.
Often, a laser surgical hand-piece used during one procedure cannot be used with another patient in a subsequent procedure unless some form of sterilization is performed. Types of sterilization techniques range from autoclaves to gas. Gas procedures are time consuming and costly. Autoclave temperatures generally have proven too severe for laser surgical hand-pieces to withstand.
Accordingly it would be useful to provide a hand-held laser surgical device, particularly suitable for cutting soft tissue, which eliminates the need for a base laser unit.
It would be of further benefit if the hand-held laser surgical device had a separate wireless foot pedal to activate the on-off switch for the surgical device, a small screen and several control buttons for surgeon interface with the instrument, thus providing a dental soft-tissue laser surgical device that is simpler and easier to use.
Another desired aspect for a hand-held laser surgical device would be a sterile, disposable tip for use with the handheld laser surgical device. It would be of further use if the sterile, disposable tip provided means for precise alignment of the optical fiber in the tip to the source of laser energy in the surgical device.
Yet another useful advantage would be for the sterile, disposable tip to be releasably attached to the device with mechanical, magnetic, electro-mechanical, or electro-magnetic locking assembly.
Finally, when not in use, the hand-held laser surgical device is stored in a rechargeable power supply base which offers ultra violet (UV) light for additional cleanliness and sterilization. Accordingly it would be useful to provide a hand-held laser surgical device for use with a sterile, disposable tip having a quick and easy to use alignment and connection assembly for use the laser surgical device, such as our disposable surgical tip apparatus disclosed and claimed in pending U.S. Non-provisional Patent Application Serial No. 12/1 15,336, filed on May 5, 2008 ["the '336 Application"] which is incorporated herein by reference for all purposes.
Further, it would be useful to provide a hand-held laser surgical device for use with a dual diode converging module, such as our dual diode converging module disclosed and claimed in pending U.S. Non-provisional Patent Application Serial No. 12/1 15,383, filed on May 5, 2008 ["the '383 Application"] which is incorporated herein by reference for all purposes.
It would be yet another advantage to provide a hand-held laser surgical device for use with a surgical laser tip apparatus with alignment assembly, such as our surgical laser tip apparatus with alignment assembly disclosed and claimed in pending U.S. Non-provisional Patent Application Serial No. 12/257,665, filed on October 244, 2008 ["the '665 Application"] which is incorporated herein by reference for all purposes.
For a more complete understanding of the above and other features, advantages, and objects of the invention, reference should be made to the following detailed description of a preferred embodiment, and to the accompanying drawings.
