Intended Use

The MISS instrument set is designed for transthoracic and transabdominal approaches to the spine. Hand instruments, such as osteotome, elevator, hook probe, spoon, curette, punch, compunction tube with obturator, and plug applicator are used for endoscopically controlled dissection, exploration, and manipulation of tissue through natural or surgically created passages. Rongeurs and punches are used under endoscopic control, to grasp, manipulate, and cut, as well as for the dissection and biopsy of tissue, organs, or foreign bodies. Suction irrigation punches are used for endoscopically controlled punching and removal of tissue through natural or surgically created passages.

Device Story

Set of manual surgical instruments including punches, rongeurs, osteotomes, elevators, spoons, curettes, probes, bone pushers, block applicators, and compaction tubes. Used by surgeons in OR for transthoracic and transabdominal spinal procedures. Instruments facilitate endoscopically controlled dissection, exploration, tissue manipulation, biopsy, and removal of tissue or foreign bodies. Devices function as mechanical extensions for the surgeon; no electronic or automated components. Benefit derived from minimally invasive access to spinal structures.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Manual surgical instruments (punches, rongeurs, osteotomes, etc.). Mechanical operation. No energy source, software, or connectivity. Sterilization method not specified.

Indications for Use
