The Senhance® Surgical System is intended to assist in the accurate control of laparoscopic instruments for visualization and endoscopic manipulation of tissue including grasping, cutting, blunt and sharp dissection, approximation, ligation, electrocautery, suturing, mobilization. The Senhance Surgical System is intended for use in general laparoscopic surgical procedures and laparoscopic gynecological surgery. The system is indicated for adult use. It is intended for use by trained physicians in an operating room environment in accordance with the instructions for use.
The Senhance Articulating platform is intended as an addition to the suite of instruments and adapters previously cleared for use with the Senhance® Surgical System ("Senhance system"). These instruments add degrees of freedom near the instrument end effector to allow for additional range of motion for the surgeon when performing laparoscopic tissue manipulations. Two articulating instruments are being added to the suite of instruments –Bipolar Atraumatic Grasper and Needle Driver. The instruments are single use and provided sterile to the end user. The instruments connect to a coupler which in turn connects to the articulating adapter which attaches to the Senhance Manipulator Arm.
The provided text, a 510(k) summary for the Senhance Surgical System, describes the device, its intended use, and substantial equivalence to predicate devices, supported by various performance tests. However, it does not contain the specific information required to complete a table of acceptance criteria and the detailed study results as requested in the prompt.
Specifically, the document does NOT include:
- A table of acceptance criteria with reported device performance (quantitative metrics are absent). The document mentions various performance tests (Biocompatibility, Reprocessing, Bench Testing, Electrical Safety, Software V&V, Pre-Clinical Design Validation, Usability Testing) but provides only qualitative statements about their success (e.g., "demonstrated that the patient-contacting portions... are non-toxic," "confirmed that the articulating instruments perform as intended," "Software verification and validation were successfully conducted," "All applicable user level requirements were assessed and found to be met," "The surgical teams were able to independently perform all critical tasks without use errors that would lead to harm"). It does not list specific numerical acceptance thresholds or the measured device performance against those thresholds.
- Sample sizes used for a "test set" in the context of AI/ML performance. While "Pre-Clinical Design Validation" involved a "simulated use design validation evaluation" with "users who represented the intended primary user population," and "Usability Testing" involved "surgical teams," these are not described as conventional "test sets" for evaluating an AI/ML algorithm's analytical performance (e.g., in terms of sensitivity/specificity).
- Data provenance (country of origin, retrospective/prospective).
- Number of experts or their qualifications for establishing ground truth.
- Adjudication method for a test set.
- Details on a Multi-Reader Multi-Case (MRMC) comparative effectiveness study, or effect size of human reader improvement with AI assistance. The device described is a surgical system with articulating instruments, not an AI software intended to assist human readers in, for example, diagnostic image interpretation.
- Details on a standalone (algorithm only) performance study. Again, this is a surgical system, not an AI algorithm evaluated in isolation.
- Type of ground truth used (expert consensus, pathology, outcomes data).
- Sample size for the training set.
- How ground truth for the training set was established.
Conclusion:
The provided document describes the regulatory submission for a surgical system, focusing on its substantial equivalence to a predicate device through various engineering and usability validations. It does not provide the specific type of information requested, which pertains more to the rigorous testing and validation of an Artificial Intelligence/Machine Learning (AI/ML) based medical device, particularly in a diagnostic or assistive interpretive role, where concepts like acceptance criteria for sensitivity/specificity, ground truth establishment by experts, and MRMC studies are common. The device described, the "Senhance Surgical System," is a robotically-assisted surgical tool with new articulating instruments, not an AI/ML diagnostic or predictive software.
§ 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.
