This study aimed to describe the design, prototyping, sterilization validation, and preliminary clinical evaluation of this instrument. Prototypes were fabricated using ABS-like Pro resin via LSPc 3D printing. EtOx (ethylene oxide) sterilization proved to be the only effective method ensuring both microbiological safety and material integrity after 25 cycles. A randomized clinical trial involving 36 female dogs compared the OFs with conventional extracorporeal suture (ES) suspension using two-port laparoscopic ovariectomy. Surgical performance was assessed via operative times and complication rates. The OF group demonstrated significantly reduced ovariectomy (7.5 \u00b1 1.6 min vs. 23.7 \u00b1 7.6 min, p &lt; 0.01) and overall surgical (14.2 \u00b1 1.7 min vs. 30.4 \u00b1 7.4 min, p &lt; 0.01) times. No intraoperative complications occurred in the OF group, while the ES group exhibited instances of needle breakage, multiple suture attempts, and increased bleeding. The OFs enabled surgical maneuvers and ovarian suspension without requiring additional incisions or complex techniques, offering ergonomic advantages and compatibility with standard optics. These findings support the OFs as a promising tool to simplify and improve minimally invasive ovariectomy in veterinary surgery.<\/jats:p>","DOI":"10.3390\/vetsci12070639","type":"journal-article","created":{"date-parts":[[2025,7,3]],"date-time":"2025-07-03T08:22:07Z","timestamp":1751530927000},"page":"639","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Design, Development, and Clinical Assessment of a Novel Patented Laparoscopic Instrument for Ovariectomy in Dogs"],"prefix":"10.3390","volume":"12","author":[{"given":"Marta","family":"Guadalupi","sequence":"first","affiliation":[{"name":"Sez.
