Dual-headed surgical instrument
The dual-headed surgical instrument is a surgical instrument with tool heads at either end for performing surgical procedures, such as, for example, skull base dissection. The dual-headed surgical instrument includes an elongated handle portion extending along a longitudinal axis. The elongated handle portion has opposed first and second ends. The first end of the elongated handle portion has a first surgical tool head and the second end of the elongated handle portion has a second surgical tool head. The first surgical tool head extends along a first tool axis which is angularly displaced from the longitudinal axis by 60°. The second surgical tool head extends along a second tool axis which is angularly displaced from the longitudinal axis by 150°. The first end of the elongated handle portion may be curved to define the 60° angle of the first tool axis.
1 . A dual-headed surgical instrument, comprising:
an elongated handle portion extending along a longitudinal axis, the elongated handle portion having opposed first and second ends,
wherein the first end has a first surgical tool head, said first surgical tool head comprising a flat surface having a semi-sharp peripheral edge and an opposing atraumatic face;
wherein the second end has a second surgical tool head, said second surgical tool head comprising either a flat surface having a semi-sharp peripheral edge and an opposing atraumatic face or a concave elliptical surface having a semi sharp peripheral edge,
wherein the first surgical tool head extends along a first tool axis, the first tool axis being angularly displaced from the longitudinal axis by 60°±2° such that the first surgical tool head is configured to reach an anterior cranial fossa of a patient,
wherein the second surgical tool head extends along a second tool axis, the second tool axis being angularly displaced from the longitudinal axis by 150°±2° such that the second surgical tool head is configured to reach both a middle cranial fossa and a posterior crania fossa of the patient,
wherein the first end of the elongated handle portion is curved with respect to the longitudinal axis,
wherein the second end of the elongated handle portion is straight with respect to the longitudinal axis,
wherein the first surgical tool head is attached the first end of the elongated handle portion that is curved with respect to the longitudinal axis, and
wherein the second surgical tool head is attached the second end of the elongated handle portion that is straight with respect to the longitudinal axis.
2 . The dual-headed surgical instrument as recited in claim 1 , wherein each of the first and second surgical tool heads comprises a dissector tool head.
3 . The dual-headed surgical instrument as recited in claim 1 , wherein the first surgical tool head comprises a dissector tool head.
4 . The dual-headed surgical instrument as recited in claim 3 , wherein the second surgical tool head comprises a scoop having said concave elliptical surface with said semi sharp peripheral edge.
