  • Tip Protector for Electrosurgical Forceps
    Patent number: 10531932
    Abstract: A tip protector for electrosurgical forceps is provided. The tip protector includes two sleeves connected by a bridge spacer. Each sleeve fits over a respective forceps tine to protect the tips of the forceps. The bridge spacer is sufficiently rigid to maintain the spacing between the tips and prevent the tines from closing or opening. In this manner, the tips can be protected from damage and the tines can be protected against misalignment.
