No reference devices were used in this submission.
No
The device description and performance studies focus on the mechanical and material properties of a trocar, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No
The device is described as having a port to insert endoscopic instruments for endoscopic procedures, serving as an access tool rather than directly performing a therapeutic function.
No
The CORE-Trocar is described as a "single-use medical device to have a port to insert endoscopic instruments for endoscopic procedures." Its function is to facilitate the insertion of instruments, not to diagnose conditions.
No
The device description clearly outlines physical components like a cannula, obturator, seals, valve, and stopcock, and the performance studies involve physical tests like insertion force, air leakage, and instrument compatibility. This indicates a hardware device, not software only.
Based on the provided information, the CORE-Trocar is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to "have a port to insert endoscopic instruments for endoscopic procedures." This describes a surgical tool used in vivo (within the body) to facilitate a medical procedure.
- Device Description: The description details a physical device (cannula and obturator) used to create an access point into the body. It focuses on mechanical and physical properties like seals, valves, and dimensions.
- Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. The CORE-Trocar does not perform any such analysis of biological specimens.
- Performance Studies: The performance studies focus on the physical and mechanical properties of the device (sterility, biocompatibility, insertion force, air leakage, seal test, instrument compatibility, shelf life) and its performance during simulated surgical procedures (insertion and cannula stability on pig skin, air leakage in conditions similar to the abdominal cavity). These are typical tests for surgical instruments, not IVDs.
In summary, the CORE-Trocar is a surgical instrument used to create access for other instruments during endoscopic procedures, which is a direct medical intervention on the patient, not an in vitro diagnostic test.

Device Description
The CORE-Trocar has a port to insert endoscopic instruments during endoscopic procedures. It consist of a cannula and a obturator. The Trocar is available in nine (9) models(IC-TC02, IC-TC02S, IC-TC03, IC-TC03S, IC-TC05S, IC-TC05S, IC-TC08, IC-TC10, IC-TC12) and the models are divided into six (6) types according to the kinds of diameter Type : 2mm Type(IC-TC02, IC-TC02S), 3mm Type(IC-TC03, IC-TC03S), 5mm Type(IC-TC05, IC-TC05S), 8mm Type(IC-TC08), 10mm Type(IC-TC10) and 12mm Type(IC-TC12). The cannula assembly have seals(main, secondary), a valve and a stopcock. The obturator has non-bladed tip. Sterilization is done with EO gas and Sterilization Assurance Level(SAL) 10° The seals prevent loss of CO2 pneumoperitoneum pressure when instruments are inserted or withdrawn.

- Acceptance Criteria
The tolerance of the nominal size should be ±10 % of the stndard.
2) Insertion force
- Test methods
When pushing the trocar into the cannula(150mm/min), apply a force below the test standard to verify that it passes through the main and secondary seals. Under the conditions of the above method, the insertion force shall be not more than 1.5 kgf.
The Insertion force of CORE-Trocar was tested, and a force averaged 0.964 kgf (min. 0.738 and max. 1.095) was found to comply with the requirements required.

1) Seal Test
- Test methods
Connect a tube at the check valve of the cannula. Connect a pressure tester and a pressure measuring instrument to the 2-way valve after connecting a 2-way valve to the end of the tube set the pressure tester at a pressure of 15mmHg. Test with the trocar ports empty, and then with 2 different diameters initially metal traversing the seal to simulate small and large laparoscopic instrument probes insertion. repeat traversing 20 times and check the leakage.
- Acceptance Criteria
The pressure should be maintained at 12~15mmHg.
- Instrument compatibility test
- Test methods
Put in and draw out the proves(Instrument) through the cannula. Repeat putting in and drawing out at least 5 times. check compatibility by O.D size(Maximum and Minimum) with instruments. The size of the probe(Instrument) is chosen as the largest and smallest model that can be inserted into each cannula.
- Acceptance Criteria No crash, damage, strong friction
- Obturator compatibility

- Test methods
When mating the obturator with the cannula, the obturator and cannula should mated properly without friction, crash, damage. And the mating force must not exceed be 26.7N
- Acceptance Criteria
It should be mated properly without friction, crash, damage. Mating force_26.7N
- Insertion & Cannula stability
- Test methods
We selected pig skin as a sample. And like the surgical conditions, a 0.5~1.5cm incision is the size of the trocar. When conducting made depending on the insertion of Trocar (Obturator + Cannula), removal of Obturator, and fixing of Cannula in conditions similar to the human abdominal cavity, the force must satisfy the acceptance criteria.
- Acceptance Criteria Insertion≤67.8N, Removal
