Abstract

An embodiment of the invention includes a medical device. The device includes a proximal handle coupled to the proximal end of an elongated member, and a distal assembly coupled to the distal end of the elongated member. The device also includes a collar coupled to the distal assembly proximate to the distal assembly. The collar is adapted to couple the distal assembly to a medical instrument.

Claims

1. A medical instrument comprising:

an elongated member having distal and proximal ends;

a proximal handle coupled to the proximal end of the elongated member;

a distal assembly coupled to the distal end of the elongated member; and

a collar coupled to the distal assembly proximate to the distal assembly;

the collar adapted to couple the distal assembly to a medical instrument, wherein the collar is integrally molded with a portion of the distal assembly;

wherein the distal assembly includes a stationary jaw; and

wherein the collar is disposed proximally of a proximal end of the stationary jaw.

2. A medical device according to claim 1, wherein the distal assembly includes a moveable jaw, and wherein the moveable jaw is pivotable relative to the stationary jaw.

3. A medical device according to claim 2, wherein a portion of the distal assembly and the collar are composed of a unitary piece of polycarbonate, a glass-filled polycarbonate, a hard grade styrene, or other plastic.

4. A medical device according to claim 3, wherein the movable jaw is composed of metal.

5. A medical device comprising:

an elongated member having distal and proximal ends;

a proximal handle coupled to the proximal end of the elongated member;

a distal assembly coupled to the distal end of the elongated member; and

a collar coupled to the distal assembly proximate to the distal assembly;

the collar adapted to couple the distal assembly to a medical instrument, wherein the collar includes a proximal socket for receiving the distal end of the elongated member, wherein the proximal socket is aligned with the distal assembly, wherein the elongated member is secured in the proximal socket such that the elongated member is coupled to at least one portion of the distal assembly, and wherein the elongated member is adhesion bonded to the proximal socket.

6. A method of coupling a medical instrument to a medical device comprising:

providing a medical device include an elongated member having distal and proximal ends, a proximal handle coupled to the proximal end of the elongated member, a distal assembly coupled to the distal end of the elongated member, and a collar coupled to the distal assembly proximate to the distal assembly; and

coupling the collar to an outside of a distal end of a medical instrument, wherein the collar is integrally molded with a portion of the distal assembly; and

wherein the distal assembly includes a stationary jaw.

7. A method of claim 6, wherein the distal assembly includes a moveable jaw, and wherein the moveable jaw is pivotable relative to the stationary jaw.

8. A method of claim 7, wherein a portion of the distal assembly and the collar are composed of a unitary piece of polycarbonate, a glass-filled polycarbonate, a hard grade styrene, or other plastic.

9. A method of claim 8, wherein the movable jaw is composed of metal.
