The device consists of an Exmoor single-use suction tube, stainless steel needle tubing, and silicone rubber tubing to maintain alignment. The device connects to external suction via a proximal ball feature. A laser fiber is inserted through the stainless steel tubing, emerging at the distal end for surgical use. The device is operated by a surgeon during procedures to simultaneously provide suction and laser delivery. By removing surgical smoke, the device improves visibility and safety for the clinician and patient. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Materials: stainless steel needle tubing, silicone rubber tubing, polyethylene handle. Design: single-use, multi-channel suction/laser delivery cannula. Energy: passive suction (external source) and laser fiber delivery. Sterilization: not specified. ## Regulatory Identification (1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon. ## Predicate Devices - House Suction/Irrigation Tube 55-0207 (manufactured by Richards) - Microstat hand-piece (Laserscope) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

SEP 1 4 1998 K981143 ( lontract: Margaret Blackmore 4 September 1998. Ref: K981143 SUMMARY OF SAFETY AND EFFECTIVENESS | Trade Name: | Dilkes Laser/Suction Cannulae | |------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Common Name: | Twin Channel Suction Tube | | Classification Name: | Unknown | | Predicate Devices: | 1. House Suction/Irrigation Tube 55-0207, manufactured by Richards,
2. Microstat hand-piece from Laserscope | | Description of Device: | This device is constructed from an Exmoor Single Use Suction Tube (MP17291), 510K 892504, a piece of stainless steel needle tubing (MP170288) identical to that used in MP170291, covered by the same 510K 892504, and a piece of silicone rubber tubing (MP180163) which is used to hold the two pieces of stainless steel tubing together in the correct position. It uses locally supplied suction tubing to connect the device to suction by pushing the tubing over the ball feature at the proximal end of the handle. The laser fibre is passed down the exposed end of the stainless steel tubing adjacent to the handle until it emerges from the distal end. The laser fibre protruding from the distal end of the instrument should be stripped and cleaved and adjusted to the required length. | | Intended Use: | Any surgical procedure within the nasal cavity, the oral cavity or the oropharynx, which requires laser surgery and suction capability to remove smoke. | | Comparison with Predicate Devices: | The size of the House Suction/Irrigation Tube is very similar to the Dilkes Laser/Suction Cannulae.

The predicate device is currently being used for suction/Laser delivery.

The materials are similar in that stainless steel is used in both cases. The handle of the subject device is polyethylene, as this is a single - use device. The predicate device is re-usable. | {1}------------------------------------------------ Image /page/1/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
