Modular surgical laser systems

Patent No. US8961040 (titled "Modular surgical laser systems") on Nov 20, 2012. The application was issued on Feb 24, 2015.

What is this patent about?

’040 is related to the field of surgical and therapeutic laser systems, specifically those utilizing semiconductor light sources for medical and dental procedures. The background context involves the need for more ergonomic, versatile, and portable laser tools that allow practitioners to perform precise soft-tissue surgery or therapy without the constraints of bulky, tethered equipment.

The underlying idea behind ’040 is the integration of a multi-wavelength laser engine into a modular, wireless architecture that decouples the heavy control logic from the physical delivery device. By combining different laser diode outputs into a single delivery fiber using a series of internal filters and reflectors, the system provides a high-energy, multi-spectral beam while maintaining a compact, handheld form factor that communicates wirelessly with both a console and a foot pedal.

The claims of ’040 focus on a wireless handheld laser generation module that serves as a self-contained surgical tool, housing its own laser source, electronic controls, and a transmission fiber. The hardware is defined by a specific mechanical interface featuring a fiber seating structure and ferrule-based connection that allows for the attachment of specialized application tips, all while being governed by a distributed wireless control scheme involving a separate console and a remote foot switch.

In practice, the invention functions by allowing the surgeon to manipulate a battery-powered handpiece that receives operational parameters from a touch-screen console via wireless signals. The laser energy is generated directly within the handheld unit or a portable module and is delivered through a disposable tip. This tip is pre-bent at specific angles—such as 30, 60, or 90 degrees—to provide better access to surgical sites without requiring the user to manually stress or bend the optical fiber during the procedure.

This approach differs from prior solutions by eliminating the traditional umbilical cord that typically tethers a handpiece to a large stationary laser source. By utilizing a split-control architecture where the foot switch and console act as remote nodes, the system provides a clutter-free environment. Furthermore, the use of a modular ferrule and housing system with precision spacers ensures high coupling efficiency between the internal laser source and the replaceable surgical tips, preventing the power loss common in modular fiber connections.

How does this patent fit in bigger picture?

Technical Landscape

In the mid-2000s when ’040 was filed, semiconductor laser systems for medical and dental applications were typically implemented using tethered, stationary consoles that relied on physical cabling for both power delivery and operational control. At a time when system architectures commonly relied on integrated, non-modular components, the coordination between the laser source, the delivery fiber, and the user interface was often fixed, making the sterilization of components and the reconfiguration of the device for different surgical wavelengths non-trivial due to hardware constraints and the lack of standardized modular interfaces.

Prosecution Position

The disclosed invention represents a technical advancement through the transition to a modular, wireless architecture that decouples the control interface from the laser delivery mechanism. By integrating a wireless remote control and a touch-screen interface with a modular laser unit capable of multiple wavelength emissions, the system overcomes the constraints of fixed-wavelength, wired devices. The architectural shift toward a removable fiber coupling system and an autoclavable handpiece with replaceable tips enables a higher degree of procedural versatility and improved clinical hygiene, achieving a technical effect where a single control module can manage diverse surgical and therapeutic tasks through interchangeable, sterile components.

Claims

The patent contains a total of 9 claims, with claim 1 serving as the sole independent claim. This independent claim focuses on a laser transmission system featuring a wireless handheld laser generation module equipped with specific fiber and attachment structures, a separate wireless control console, and a wireless remote foot switch. The dependent claims serve to further define the system by detailing the internal laser chip configurations, multi-wavelength emission capabilities, heat sink and monitoring components, and the inclusion of a docking port on the console for recharging the handheld module.

Term (Source)Support for SpecificationInterpretation
Ferrule
(Claim 1)
The fiber 10 is encased in a ferrule 12 at its free end. The ferrule 12 is then inserted into a fiber seating structure 14, which is then inserted into an outer casing 16. The outer casing 16 then receives the tip attachment structure 18 of the surgical tip 20.A structural component encasing the free end of the laser transmission fiber to facilitate alignment and seating within the handpiece.
Fiber seating structure
(Claim 1)
The ferrule 12 is then inserted into a fiber seating structure 14, which is then inserted into an outer casing 16. The outer casing 16 then receives the tip attachment structure 18 of the surgical tip 20.A mechanical component designed to receive and secure the fiber ferrule, ensuring proper positioning of the fiber relative to the application tip.
Laser application tip
(Claim 1)
Both embodiments feature a laser module with multiple wavelength emission capability, a touch screen consol, a new fiber coupling system and replaceable therapeutic/surgical tips. The outer casing 16 then receives the tip attachment structure 18 of the surgical tip 20.A replaceable surgical or therapeutic component that attaches to the laser generation module to deliver laser energy to a target site.
Remote control foot switch
(Claim 1)
To accomplish these objectives, the laser system according to the invention is practiced in two embodiments, both of which comprise a control module and a remote foot pedal operation control. The present invention, an improvement over the Parent, utilizes a modular system with wireless control, touch screen programming, a removable fiber cable, autoclaveable hand piece, and versatile surgical tips.An external pedal device that communicates wirelessly with the laser generation module to trigger or regulate laser emission.
