Intended Use

Surgify Halo is a sterile surgical burr indicated for shaping and removal of hard tissue and bone in Neurosurgical, Spinal, ENT and general surgical procedures.

Device Story

Surgify Halo is a sterile, single-use rotary surgical burr designed for use with compatible high-speed surgical drill systems in open surgical procedures. The device features a shank for motor attachment and a head with two cutting edges. A unique integrated safety mechanism, consisting of a spring and a moving ring, is located in the burr head. This mechanism is self-centering; in one position, the ring protrudes above the cutting edges to prevent contact with underlying tissue, while in the second position, it retracts to allow the burr to cut bone. Operated by surgeons in clinical settings, the device reduces chattering during bone removal. The safety mechanism provides a physical barrier to protect soft tissue, potentially reducing surgical complications. The device is supplied sterile via gamma irradiation.

Clinical Evidence

No clinical data. Evidence consists of non-clinical bench testing, including design verification (durability, cutter efficiency, chatter, thermal, noise), summative usability testing (nurses and surgeons), and animal performance testing comparing the Surgify Halo to conventional diamond and fluted burrs. Biocompatibility was confirmed per ISO 10993-1:2018. Sterilization (gamma irradiation) and shelf-life were validated per EN/ISO 11137-1/2 (2015) to achieve a SAL of 10^-6. Transportation was validated per ISTA 3A.

Technological Characteristics

Rotary surgical burr; metallic construction. Features a spring-loaded ring mechanism for chatter reduction and tissue protection. Dimensions: 85 mm and 140 mm lengths; 5.55 mm head diameter. Max speed 37,500 RPM. Compatible with standard high-speed surgical drill systems. Single-use; supplied sterile via gamma irradiation (25 kGy). Packaging compliant with ISO 11607. Mechanical operation; no software or electronic components.

Indications for Use

Indicated for adult patients requiring hard tissue or bone shaping and removal during neurosurgical, spinal, ENT, or general surgical procedures. Contraindicated in patients with allergies or hypersensitivity to medical-grade stainless steel or its alloying components (e.g., nickel).

Regulatory Classification

Identification

Powered simple cranial drills, burrs, trephines, and their accessories are bone cutting and drilling instruments used on a patient's skull. The instruments are used with a power source but do not have a clutch mechanism to disengage the tip after penetrating the skull.

#### ���� Device Description

The Surgify Halo is a rotary cutting device made of high-grade metallic materials. It cuts bone and other hard tissues selectively while reducing chattering. The device is similar to conventional surgical cutting burrs with the addition of a ring mechanism installed in the burr head to reduce chattering. Similar to conventional burrs, the device is designed for use with compatible high-speed surgical drill systems.

The Surgify Halo comprises:

- A shank, which transfers rotary movement of the drill motor to the head. 1.
- 2. Locking features at the distal end of the shank which allow the burr shank to be locked to a high-speed surgical drill.
- റ്റ് A head that is shaped to have two cutting edges to cut bone and hard tissue.
- 4. A safety mechanism consisting of a ring and spring installed in the burr head. The mechanism is self-centering and comprises a spring and a moving ring that is bigger than the burr head. The moving ring can have two different positions:
- In the first position, the ring protrudes to a level higher than cutting edges and a. prevents the cutting edges from cutting into the work material.
- b. In the second position, the ring retracts into the groove to a level lower than the cutting edges to allow the burr to cut the work material
