Intended Use
This instrument has been designed to be used with Olympus endoscopes and electrosurgical units to cut tissue within the digestive tract using high-frequency current.
Device Story
Single Use Electrosurgical Knife Series (models KD-610L, KD-611L, KD-620LR, KD-630L, KD-640L) are endoscopic accessories used for tissue cutting in the digestive tract. Devices connect to Olympus endoscopes and electrosurgical units; they deliver high-frequency current to perform dissection. Specific designs include: isolation tips (KD-610L/611L) to prevent deep cauterization; rotatable L-shaped tip (KD-620LR) for longitudinal/lateral dissection; adjustable flexible wire (KD-630L); and triangle tip (KD-640L) for hooking tissue without rotation. Operated by physicians in clinical settings. Output is mechanical tissue cutting facilitated by electrical energy. Benefits include precise tissue resection during endoscopic procedures.
Clinical Evidence
Bench testing only.
Technological Characteristics
Electrosurgical instruments for endoscopic use. Features include isolation tips, rotatable L-shaped tips, adjustable flexible wires, and triangle tips. Energy source: high-frequency current from compatible electrosurgical units. Single-use, sterile, endoscopic accessories.
Indications for Use
Indicated for use in patients requiring tissue cutting within the digestive tract via high-frequency current, utilizing Olympus endoscopes and electrosurgical units.

#### Device Description 4
The following five models of Single Use Electrosurgical Knives are the subject of this 510(k) notification: KD-610L, KD-611L, KD-620LR, KD-630L and KD-640L.
The KD-610L and KD-611L knives have isolation tips on the distal tip to prevent inadvertent deep cauterization. The KD-611L knive also has an electrode at the bottom of the isolation tip, which can also cut tissue.
The KD-620LR knive is a L-shaped knife, which cutstissue by hooking the mucous membrane. This device is rotatable so that both longitudinal and lateral dissection is possible.
The KD-630L knife consists of flexible wire, which is adjustable by the user, preventing inadvertent deep cauterization.
The KD-640L knife has a triangle tip to the distal end of the knife, which hooks mucous membrane to cut. Both longitudinal and lateral dissection is possible without rotating the instrument due to the triangle tip design.
#### 5 Indications for Use
Single Use Electrosurgical Knife KD-610L/KD-611L/KD-620LR/KD-630L/KD-640L This instrument has been designed to be used with Olympus endoscopes and electrosurgical units to cut tissue within the digestive tract and using high-frequency current.
#### Comparison of Technological Characteristics હે
The Single Use Electrosurgical knives are basically identical to the predicate device in intended use, and similar in specifications except for cutting knife shapes.
#### 7 Conclusion
When compared to the predicate device, the Single Use Electrosurgical Knives do not incorporate any significant changes that could affect the safety or effectiveness of the device.
