• Device Name: GRASPING FORCEPS, RIGHT AND LEFT CURVED
• Applicant: Richard Wolf Medical Instruments Corp.
• Product Code: GEI · General, Plastic Surgery
• Decision Date: Sep 8, 1997
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 878.4400

• Attributes: Therapeutic

Intended Use

The instruments are for use on the laryngeal anatomy, e.g., the vocal cords, false cords, surpraglottis, glottis, epgilottis, tongue base, oral pharynx, and uvula. The instruments are used to grasp and hold tissue for dissection or vaporization. The forceps may be used to coagulate blood vessels within the tissue when it is connected to a unipolar high frequency generator. Depending on where the bleeding vessel is located, coagulate by applying a low dose of HF current. The intensity depends on the severity of the bleeding and on the vessel. Always start with a low dosage and increase the power if necessary.

Device Story

Unipolar HF grasping forceps; used for laryngeal surgery; enables tissue grasping, holding, dissection, vaporization, and coagulation. Device connects to external unipolar high-frequency generator; operator applies HF current to coagulate bleeding vessels. Used by clinicians in surgical settings. Benefits include combined mechanical grasping and electrosurgical hemostasis in laryngeal procedures.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

Medical grade stainless steel, teflon-coated stainless steel, black chrome plating, and plastic. Unipolar HF energy source. Insulated shaft for high-frequency current delivery. Manual operation.

Indications for Use

Indicated for use on laryngeal anatomy (vocal cords, false cords, supraglottis, glottis, epiglottis, tongue base, oral pharynx, uvula) to grasp, hold, dissect, vaporize tissue, and coagulate blood vessels. Contraindicated in the presence of flammable anesthetics.

Regulatory Classification

Identification

An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current.
