The Sonicision Cordless Ultrasonic Dissection Device is indicated for soft tissue incisions when bleeding control and minimal thermal injury are desired. The device can be used as an adjunct to or substitute for electrosurgery, lasers, and steel scalpels in general, plastic, gynecologic, urologic, exposure to orthopedic structures (such as spine and joint space) and other open and endoscopic procedures. The Sonicision Cordless Ultrasonic Dissection Device can be used to coagulate isolated vessels up to 5 mm in diameter.
The Sonicision 13 cm device is also indicated for use in otorhinolaryngologic (ENT) procedures.
The Sonicision Ultrasonic Dissection Device that is the subject of this 510(k) is a hand-held batterypowered device used to dissect through tissues and to coagulate vessels up to 5 mm in diameter. An assembled Sonicision device includes three components: (1) The Sonicision Dissector, 13 cm; (2) the Sonicision Battery; and (3) the Sonicision Generator. The dissector is a single-use item that is provided to the user in sterile form. The generator and battery are reusable components that are sterilized by the user. The clinical intended use is achieved by the surgeon when pressure is applied to tissue placed between the clamping jaw and the exposed portion of the probe while activating ultrasonic energy with a button on the handpiece.
The provided text does not contain information about the acceptance criteria and the study that proves the device meets them in the format of a clinical study or performance goals with specific metrics for a new AI/software device. Instead, the document is a 510(k) summary for a physical medical device – the Sonicision Cordless Ultrasonic Dissection Device – seeking clearance based on substantial equivalence to a predicate device.
The "performance" section describes comparative ex vivo and in vivo testing to demonstrate that the new device performs similarly to predicate devices, particularly for its proposed use in Otorhinolaryngology (ENT) procedures.
Here's a breakdown of the available information, adapted to the requested format where possible, but highlighting that this is not a study proving an AI/software device meets acceptance criteria:
Study Type: Substantial Equivalence Evaluation for a Physical Surgical Device
1. Table of Acceptance Criteria and Reported Device Performance
| Performance Characteristic | Acceptance Criteria (Implicit - based on Predicate) | Reported Device Performance (Sonicision) |
|---|---|---|
| Vessel Burst Strength (Ex vivo) | Comparable to FOCUS+ device | Blood vessels coagulated by Sonicision had comparable burst strength to those coagulated by FOCUS+. |
| Max Active Blade Temperature (Ex vivo) | Comparable to FOCUS+ active blade | Maximum temperature of Sonicision active blade was comparable to FOCUS+ active blade after multiple activations on mesentery. |
| Max Distal Shaft Temperature (Ex vivo) | Comparable to Thunderbeat distal shaft | Maximum temperature of Sonicision distal shaft was comparable to Thunderbeat distal shaft after multiple activations on mesentery in ultrasonic mode. |
| Hemostasis Rates (Acute In vivo) | Comparable to FOCUS+ device | Sonicision device and FOCUS+ device achieved comparable rates of hemostasis. |
| Clinical Acceptability (Usability/Human Factors) | Clinically acceptable for ENT surgical procedures (subjective) | Practicing surgeons found the 13 cm Sonicision device to be clinically acceptable for use in ENT surgical procedures. |
2. Sample size used for the test set and the data provenance
- Vessel Burst Testing: Not specified, but involved "blood vessels."
- Ex vivo Tissue Testing (Temperatures): Not specified, but involved "mesentery."
- Acute In vivo Testing (Hemostasis): Not specified.
- Usability/Human Factors Validation: Not specified, but used a "human cadaver model."
The data provenance is from ex vivo (tissue from outside a living organism, likely animal or human cadaveric) and in vivo (within a living organism, likely animal) studies, along with human cadaver model studies. The country of origin is not specified but implicitly within the context of FDA submission, suggesting studies conducted under applicable US regulations or international standards.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Usability/Human Factors Validation: Involved "practicing surgeons" who were "predominantly users of the FOCUS+ device for ENT surgeries." The exact number is not specified, nor are specific years of experience. For the other performance tests (burst strength, temperatures, hemostasis), the ground truth is objective measurement, not expert consensus.
4. Adjudication method for the test set
- Not applicable as the performance tests primarily involved objective measurements rather than subjective assessments requiring adjudication. For the usability study, the "ground truth" was the surgeon's subjective assessment of clinical acceptability, not a formally adjudicated outcome.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No MRMC comparative effectiveness study was done. This document pertains to a physical surgical device, not an AI/software device. The usability study involved human operators using the device, but it was not an MRMC study comparing human reader performance with and without AI assistance.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. This relates to a physical surgical device, not an algorithm.
7. The type of ground truth used
- Vessel Burst Strength: Objective measurement (burst pressure).
- Max Active Blade Temperature: Objective measurement (temperature readings).
- Max Distal Shaft Temperature: Objective measurement (temperature readings).
- Hemostasis Rates: Objective observation of bleeding control.
- Clinical Acceptability (Usability/Human Factors): Expert subjective assessment/opinion from practicing surgeons.
8. The sample size for the training set
- Not applicable. This is a physical device, and the described studies are for performance validation, not for training an algorithm.
9. How the ground truth for the training set was established
- Not applicable. (See point 8)

The Sonicision™ Cordless Ultrasonic Dissection Device is indicated for soft tissue incisions when bleeding control and minimal thermal injury are desired. The device can be used as an adjunct to or substitute for electrosurgery, lasers, and steel scalpels in general, plastic, pediatric, gynecologic, urologic, exposure to orthopedic structures (such as spine and joint space) and other open and endoscopic procedures. The Sonicision Cordless Ultrasonic Dissection Device can be used to coagulate isolated vessels up to 5 mm in diameter.
The Sonicision™ Cordless Ultrasonic Dissection Device is a hand-held surgical device consisting of three interdependent components that, when assembled, enable ultra high-frequency mechanical motion (ultrasonic energy) to transect, dissect, and coagulate tissue. The Sonicision device is designed to be both ergonomic and intuitive for the user. It can coagulate vessels up to and including 5 mm in diameter and is designed to be inserted and extracted through a compatible 5 mm trocar, when used endoscopically/laparoscopically. A unique characteristic of the device is that it functions without the need for external power cords and transducer cables. Sonicision generators and batteries are prepared by the facility and attached to the dissector (disposable component). When assembled, electrical power supplied by the battery pack is available to be converted to ultrasonic energy in the generator. The clinical intended use is achieved by the surgeon when pressure is applied to tissue placed between the clamping jaw and the exposed portion of the probe while activating ultrasonic energy through the use of a two-stage button. The system is comprised of single-use and reusable components.
The provided text describes the 510(k) summary for the Sonicision™ Cordless Ultrasonic Dissection Device. It details the device's description, intended use, and technological/performance characteristics, along with a summary of non-clinical/preclinical performance. However, it does not contain specific acceptance criteria tables nor comparative study results with human readers or standalone algorithm performance as requested in the prompt. The information provided is primarily for demonstrating substantial equivalence to predicate devices, focusing on design features and non-clinical testing.
Therefore, many of the requested details cannot be extracted from the provided document.
Here's a summary of what can be extracted and what cannot:
1. A table of acceptance criteria and the reported device performance:
The document describes various performance aspects that were evaluated to demonstrate substantial equivalence, but it does not present them in a formal table with specific acceptance criteria (e.g., "burst pressure > X mmHg") and corresponding reported values. Instead, it states that the device "performs at least as well as (not inferior to) the predicate ultrasonic device."
- Evaluated areas: Active blade displacement, frequency, grasping and pulling force, shaft deflection, distal seal leakage, button activation force, jaw clamping force, temperature, isolated vessel burst pressures/hemostasis, coagulation and dissection speed, qualitative ratings of sealed tissue, thermal spread, and enterotomy formation speed and hemostasis.
- Performance Outcome: "performs at least as well as (not inferior to) the predicate ultrasonic device (Harmonic ACE36E)"
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- Sample Size for Test Set: Not specified for individual tests. The preclinical studies used "porcine" models.
- Data Provenance: Porcine (animal) studies for preclinical evaluations. The document does not specify a country of origin for the studies.
- Retrospective or Prospective: These were primarily prospective preclinical studies using animal models.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
Not applicable. The "ground truth" here is based on objective measurements and observations in bench and animal studies (e.g., vessel burst pressure, tissue integrity), not on expert interpretations of medical images or data.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable. This type of adjudication method is used for establishing ground truth in expert-based studies, which is not what was performed here.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
Not applicable. This device is a surgical instrument, not an AI diagnostic tool. No MRMC study or AI assistance evaluation was performed.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This is a physical surgical device, not an algorithm. Performance was evaluated in non-clinical, preclinical (bench/animal), and usability studies, which involve the device in operation.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
The "ground truth" in this context was established through:
- Objective measurements in non-clinical (electrical/mechanical/functional) testing: e.g., direct measurements of active blade displacement, frequency, forces, leakage.
- Preclinical (bench tissue/animal) evaluations: using direct observation, measurement, and histological assessment of tissue effects (e.g., isolated vessel burst pressures, coagulation speed, thermal spread, enterotomy formation).
8. The sample size for the training set:
Not applicable. The device is not an AI algorithm that requires a training set. Its development and validation are based on engineering design, material science, and physical testing.
9. How the ground truth for the training set was established:
Not applicable, as there is no training set for an AI algorithm.
