I-Medical zoom/focus coupler iyithuluzi elisetshenziswa emkhakheni wezokwelapha ukuze kuthuthukiswe ukubonakala ngeso lengqondo phakathi nezinqubo zokwelapha, ikakhulukazi ku-endoscopy kanye ne-microscope. Idizayinelwe ukuxhuma phakathi kwesistimu yokucabanga yezokwelapha kanye nensimbi yokubona, njenge-endoscope noma isibonakhulu, evumela amandla okusondeza nokugxila.I-coupler ivumela amazinga ahlukahlukene okukhulisa, okuvumela ochwepheshe bezokwelapha ukuthi balungise izinga lokusondeza ukuze babhekisise futhi bahlaziye indawo eqondiwe. Iphinde inikeze amandla ukugxila okunembayo, iqinisekisa ikhwalithi ephezulu yesithombe nokucaca ngesikhathi senqubo. Idivayisi ngokuvamile ihlanganisa i-optics yekhwalithi ephezulu, eqinisekisa ukuhlanekezelwa kwesithombe okungahlanekezelwe nokunokulungiswa okuphezulu.I-zoom/focus coupler iyithuluzi elibalulekile kuzilungiselelo zezokwelapha, njengoba isiza ekuxilongeni okunembile, izinqubo zokuhlinzwa ezisebenzayo, kanye nokuboniswa okuphelele kwezisebenzi zezokwelapha. Ngamandla ayo okusondeza okulungisekayo nokugxila, ithuthukisa ukunemba nokusebenza kahle kwezinqubo zezokwelapha, inikeze imiphumela engcono ezigulini.
