Abstract
The present invention is improved handles incorporated with a microsurgical instrument. The microsurgical instrument has a pair of crisscrossed members each having a forward functional portion and a rearward portion. Each of the rearward portions of the pair of crisscrossed members is substantially widened for accommodating the fingers of a surgeon's hand, such that the fingers are positioned parallel to the general longitudinal profile of the microsurgical instrument. The forward functional portions may be microsurgical scissors, microsurgical needle holders, microsurgical Aneurysmen clips, and the like.
Claims32
A microsurgical instrument, comprising:
- a. a first elongated member having a front end, a rear end, a functioning portion adjacent to its front end, a handle portion adjacent to its rear end, and an arm portion interconnecting its functioning portion and its handle portion;
- b. a second elongated member having a front end, a rear end, a functioning portion adjacent to its front end, a handle portion adjacent to its rear end, and an arm portion interconnecting its functioning portion and its handle portion;
- c. connecting means for hingeably attaching said first and second elongated members in a crisscross manner at a joint between their said functioning portions and said arm portions;
- d. said handle portions of said first and second elongated members each having a substantially widened outer surface;
- e. said substantially widened outer surface of said handle portion of said first elongated member having a longitudinal groove for accommodating the thumb of a surgeon's one hand, and said substantially widened outer surface of said handle portion of said second elongated member having two longitudinal grooves for accommodating the index and middle fingers of the surgeon's same hand;
- f. said longitudinal groove on said substantially widened outer surface of said handle portion of said first elongated member for accommodating the thumb of a surgeon's one hand extends the entire length of said handle portion of said first elongated member;
- and
- g. biasing means attached and disposed between said handle portions of said first and second elongated members without extending beyond said rear ends of said first and second elongated members for keeping said first and second elongated members in a balanced position.
