Abstract
An improved surgical instrument with detachable tool member (10). The surgical instrument (10) comprises at least one tool member (14) defining a work portion (15) and a rearward end portion (16). The rearward end portion (16) is provided with a tenon (28) for detachably mounting the tool member (14), the tenon (28) defining a narrowed waist portion (34) and an expanded portion (36) rearward of the waist portion (34). The tool member (14) is also provided with a locking rod receptor (42) defining an opening in the rearward end portion (16). The surgical instrument (10) also comprises a tool support member, which in alternate embodiments defines a handle (12) and flexible shaft (48) having a flexible shaft (49). The tool support member includes an outboard end portion (32) provided with a mortise (30) for closely receiving the tenon (28) of the tool member (14) and is further provided with a locking rod passageway (40) defining an opening in the outboard end portion (32) registering with the receptor (42) of the tool member (18). In order to prohibit the tenon (28) from moving laterally within the mortise (30), an elongated locking rod (38) is slidably received in the passageway (40) and in the receptor (42), thereby securing the tenson (28) in the mortise (30).
