Modular surgical laser systems

Patent No. US8337097 (titled "Modular surgical laser systems") on Feb 21, 2008. The application was issued on Dec 25, 2012.

What is this patent about?

’097 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 improved portability and versatility in clinical environments, moving away from bulky, tethered equipment toward modular systems that offer better fiber management and more intuitive user interfaces.

The underlying idea behind ’097 is the integration of a multi-wavelength laser engine into a modular, wireless architecture that simplifies the delivery of therapeutic light. By combining multiple laser chips and detector chips through a series of filters and reflectors, the system merges distinct wavelengths into a single output fiber. This allows a practitioner to switch between or combine different therapeutic effects without changing hardware, all while maintaining a sterile field through wireless control and autoclavable components.

The claims of ’097 focus on a portable laser transmission system that utilizes a battery-powered console acting as the central hub for laser generation and control. The system is defined by its specific connection architecture, which includes a laser transmission fiber ending in a ferrule that seats into a specialized housing. This housing facilitates a secure, aligned connection to a disposable application tip, while the entire firing sequence is managed by a wireless foot switch to eliminate physical cable obstructions.

In practice, the invention works by utilizing a unique fiber-to-fiber coupling mechanism that employs precision spacers and optical lenses to maximize light transfer efficiency between the main console and the surgical tip. The system can be implemented either as a stationary console with a tethered handpiece or as a fully mobile, battery-operated handheld unit. The use of a slotted cylindrical housing allows for automatic alignment of ferrules, ensuring that even with minor manufacturing variances, the laser energy is focused accurately into the delivery fiber.

This approach differs from prior solutions by replacing rigid, single-wavelength delivery with a disposable tip architecture that pre-encases the fiber at specific angles. Unlike traditional systems where fibers are repeatedly bent or stressed during insertion into cannulas, these tips are factory-set at angles ranging from 0° to 90°. This reduces mechanical strain on the glass and ensures consistent beam quality, while the wireless foot switch and touch-screen interface provide a level of ergonomic freedom not found in older, hard-wired surgical lasers.

How does this patent fit in bigger picture?

Technical Landscape

In the mid-2000s when ’097 was filed, semiconductor-based surgical and therapeutic laser systems were typically implemented using fixed, tethered architectures where control interfaces and power delivery were physically integrated into a stationary console. At a time when medical laser systems commonly relied on wired foot switches and permanent fiber optic attachments for beam delivery, hardware and software constraints made the implementation of reliable wireless control protocols and modular, hot-swappable optical components non-trivial. Engineering practices during this era generally prioritized high-voltage stability over portability, often resulting in bulky systems that lacked intuitive, touch-sensitive user interfaces or the ability to easily sterilize and replace distal delivery components between procedures.

Prosecution Position

The disclosed invention represents a technical advancement through the architectural shift from a monolithic laser device to a modular, wireless system that decouples the control interface from the laser delivery mechanism. By integrating a wireless remote control and a touch-screen programming interface with a multi-wavelength laser module, the system overcomes the technical constraints of limited maneuverability and rigid wavelength selection inherent in traditional surgical lasers. The technical effect achieved is a more versatile and sterile surgical environment enabled by the combination of an autoclavable handpiece, a removable fiber cable coupling system, and replaceable surgical tips, which collectively allow for rapid reconfiguration and improved hygiene maintenance without compromising the precision of the laser delivery.

Claims

The patent contains a total of 8 claims, with claim 1 serving as the sole independent claim. This independent claim focuses on a portable laser transmission system comprising a console with a laser generation module, a specialized fiber connection structure for an application tip, and a wireless foot switch for remote operation. The dependent claims serve to further specify the system's hardware by introducing a docking station for recharging, detailing the internal components of the laser generation module such as heat sinks and monitor chips, and defining the optical arrangement for combining multiple laser wavelengths into a single output.
