The EndoWrist Vessel Sealer is a bipolar electrosurgical instrument for use with a compatible da Vinci Surgical System and the ERBE VIO dV electrosurgical generator. It is intended for grasping and blunt dissection of tissue and for bipolar coagulation and mechanical transection of vessels up to 7 mm in diameter and tissue bundles that fit in the jaws of the instrument. The EndoWrist Vessel Sealer has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures, and should not be used for these procedures.
The 8 mm Harmonic ACE Curved Shears is intended for soft tissue incisions when bleeding control and minimal thermal injury are desired. It is designed to be used in conjunction with a compatible da Vinci Surgical System and a compatible Ethicon Endo-Surgery Generator and Hand Piece.
The Intuitive Surgical da Vinci Single-Site Instruments and Accessories used with a compatible da Vinci Surgical System are indicated for use by trained physicians in an operating room environment for endoscopic manipulation of tissue, grasping, cutting, blunt and sharp dissection, approximation, clip-ligation, electrocautery, suction/irrigation and suturing during single incision laparoscopic cholecystectomy, benign hysterectomy and salpingo-oophorectomy with the da Vinci Single-Site Instruments and Accessories, including graspers, dissectors, needle drivers, scissors, suction irrigators, monopolar cautery, bipolar cautery, clip appliers, 5 mm curved cannulae, 5 mm and 10 mm straight cannulae, 8 mm endoscope cannula, flexible and rigid blunt obturators, cannula seal, and the Single-Site Port.
The EndoWrist Vessel Sealer is a sterile, single-use (disposable), 8 mm instrument with an integrated cord that connects to the instrument housing and an Erbe VIO dV generator. The EndoWrist Vessel Sealer device consists of a distal wristed end effector and a proximal housing connected by a tubular shaft. The housing contains mechanisms to actuate the end effector when attached to a compatible da Vinci Surgical System. An integrated cord attached to the housing is connected to a receptacle in the IESU. An electrode sealing surface and a cutting blade within the jaws of the instrument enable sealing of vessels and cutting of sealed vessels and other tissues. The sealing and cutting functions are controlled using the compatible da Vinci Surgical System foot pedals.
The da Vinci 8 mm Harmonic ACE Curved Shears is a single-use, sterile instrument used to deliver ultrasonic energy to enable transection and coagulation of tissue. The movement and function of the da Vinci 8 mm Harmonic ACE Curved Shears are controlled by the surgeon from the Surgeon Console of a compatible da Vinci Surgical System. This instrument consists of a housing, instrument shaft, and instrument jaws comprised of a clamp arm and blade.
The da Vinci Single-Site Instruments and Accessories are a set of devices developed by Intuitive Surgical to enable single incision laparoscopic cholecystectomy, benign hysterectomy and salpingo oophorectomy using the compatible da Vinci Surgical System.
This document is a 510(k) premarket notification from the FDA, classifying the submitted devices as substantially equivalent to previously marketed devices. The purpose of this submission is to change the Indications for Use for three devices: the EndoWrist Vessel Sealer, 8 mm Harmonic ACE Curved Shears, and da Vinci Single-Site Instruments and Accessories. The document explicitly states that design verification and validation testing were not required as design inputs were not changed.
Therefore, there is no information about specific acceptance criteria, device performance, or a study that proves the device meets acceptance criteria presented in this document. The submission is focused on modifying the labeling regarding compatible systems.
Consequently, I cannot provide the requested information from the given text as it does not contain details about:
- A table of acceptance criteria and reported device performance.
- Sample sizes or data provenance for a test set.
- Number of experts or their qualifications for ground truth establishment.
- Adjudication method.
- MRMC comparative effectiveness study or related effect size.
- Standalone algorithm performance.
- Type of ground truth used (e.g., pathology, outcomes data).
- Sample size for the training set.
- How the ground truth for the training set was established.
The document essentially states that the devices are identical to their predicate devices and the changes are only to the wording of the Indications for Use regarding compatibility with different da Vinci Surgical System models.
§ 876.1500 Endoscope and accessories.
(a)
Identification. An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.(b)
Classification —(1)Class II (special controls). The device, when it is an endoscope disinfectant basin, which consists solely of a container that holds disinfectant and endoscopes and accessories; an endoscopic magnetic retriever intended for single use; sterile scissors for cystoscope intended for single use; a disposable, non-powered endoscopic grasping/cutting instrument intended for single use; a diagnostic incandescent light source; a fiberoptic photographic light source; a routine fiberoptic light source; an endoscopic sponge carrier; a xenon arc endoscope light source; an endoscope transformer; an LED light source; or a gastroenterology-urology endoscopic guidewire, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I for the photographic accessories for endoscope, miscellaneous bulb adapter for endoscope, binocular attachment for endoscope, eyepiece attachment for prescription lens, teaching attachment, inflation bulb, measuring device for panendoscope, photographic equipment for physiologic function monitor, special lens instrument for endoscope, smoke removal tube, rechargeable battery box, pocket battery box, bite block for endoscope, and cleaning brush for endoscope. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807of this chapter, subject to the limitations in § 876.9.
