Forceps for performing endoscopic surgery
First Claim
1. A body assembly of a surgical instrument for performing endoscopic surgery, said handle assembly comprising:
- a housing defining an axial bore;
said housing defining a transverse bore extending along a transverse axis and opening to said axial bore;
a lock slidably disposed in said transverse bore along said transverse axis for sliding into said axial bore to engage a tube adaptor and for sliding out of said axial bore to disengage the tube adaptor;
a latch extending from said lock to an end portion; and
said latch defining a pivot axis for pivoting said latch about said pivot axis as said lock slides into or out of said axial bore.

Abstract
A surgical instrument for performing surgery includes a housing defining an axial bore. A lock is slidably disposed in the transverse bore to engage and disengage a tube adaptor. A latch extends from the lock to move the latch into and out of the axial bore. The lock and latch allow for interchangeability of tip assemblies inserted into the surgical instrument. A first and second handle are pivotally attached to the housing. A first ratchet member is rotatably attached to the first handle and includes serrated teeth. A second ratchet member extends from the second handle. The second ratchet member including a finger for engagement with the serrated tooth to prevent movement of said first handle relative to the second handle. The first ratchet member is rotatable about the rotational axis to disengage from the second ratchet member and allow the first handle to move relative to the second handle.

17. A surgical instrument for performing endoscopic surgery, said surgical instrument comprising:
-
a housing defining an axial bore extending along a tube axis, said housing defining a transverse bore extending along a transverse axis and opening to said axial bore, a lock slidably disposed in said transverse bore along said transverse axis for sliding into said axial bore to engage a tube adaptor and for sliding out of said axial bore to disengage the tube adaptor, a latch extending from said lock to an end portion with said latch defining a pivot axis for pivoting said latch about said pivot axis as said lock slides into or out of said axial bore; a tube assembly defining a cable opening extending along said tube axis to receive a tip insert for performing the endoscopic surgery; and said tube assembly defining a groove for receiving said lock to retain said tube assembly to said housing when said lock is disposed in said groove.

18. A surgical instrument for performing endoscopic surgery, said surgical instrument comprising:
-
a housing; a first handle pivotally attached to said housing; a first ratchet member defining a rotational hole on a rotational axis with said first ratchet pivotally attached to said first handle for rotating about said rotational axis relative to said first handle; said first ratchet member including at least one serrated tooth; a second handle pivotally attached to said housing; a second ratchet member extending from said second handle; said second ratchet member including a finger for engagement with said at least one serrated tooth of said first ratchet member to prevent movement of said first handle relative to said second handle; and said first ratchet member rotatable about said rotational axis to disengage said at least one serrated tooth from said finger to allow said first handle to move relative to said second handle. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
