Abstract:
1. A surgical tool for capturing and removing intraocular foreign bodies, comprising: an elongate base; an elongate bore formed in said elongate base, said elongate bore having a leading end in open communication with a leading end of said elongate base; a foreign body capturing means slideably received within said elongate bore; said foreign body capturing means including an elongate handle, a rim, and a net; a control member connected to said foreign body capturing means for controlling the instantaneous position of said foreign body capturing means; said foreign body capturing means having a fully retracted position where said foreign body capturing means is substantially received within said elongate bore, a fully extended position where said foreign body capturing means is fully extended from said elongate bore, and an infinite number of functional positions of adjustment therebetween; an elongate slot formed in a top wall of said elongate base in parallel relation to said elongate bore; said elongate slot having a length substantially equal to a length of said elongate bore; said control member being slideably mounted to said top wall of said elongate base; said control member having a fully retracted position, a fully extended position, and an infinite number of functional positions of adjustment therebetween; a rigid rod extending through said elongate slot and interconnecting said control member and said handle of said foreign body capturing means; said fully retracted position of said control member corresponding to said fully retracted position of said foreign body capturing means and said fully extended position of said control member corresponding to said fully extended position of said foreign body capturing means; said elongate slot having a width less than a width of said elongate bore; a truncate slot formed in a bottom wall of said elongate base in parallel relation to said elongate bore; said truncate slot having a length less than said length of said elongate bore; said truncate slot having a leading end in open communication with said leading end of said elongate base; said truncate slot having a length equal to about half that of said elongate bore and being in open communication with a leading half of said elongate bore; said net having an upper end mounted about a perimeter of said rim and said net having a main body, integral with said upper end, that depends from said upper end when said foreign body capturing means is in fully retracted position, said fully extended position, and said infinite member of functional positions of adjustment therebetween; said truncate slot having a width greater than a width of said elongate slot but less than a width of said elongate bore, said width difference creating a shoulder that supports said rim when said foreign body capturing means is in said fully retracted position; and said net extending below said bottom wall of said elongate base when said foreign body capturing means is in said fully retracted position, and said net extending below a plane defined by said bottom wall of said elongate base when said foreign body capturing means is in said fully extended position and any of said infinite number of functional positions of adjustment between said fully extended and fully retracted positions.
