Abstract

A treatment assembly for securing a treatment member to a shaft that includes the treatment member and a female attachment member. The treatment member defines a longitudinal axis, and has a distal end and a proximal end. The proximal end includes an attachment recess defined therein. The female attachment member has a distal end, a proximal end, and a shaft recess defined in the proximal end. The female attachment member is secured in the attachment recess of the treatment member. The shaft recess is defined by an interior surface that includes a first flat surface. The interior surface includes a first detent defined therein. When the shaft is received in the shaft recess, the first flat surface is operatively engaged with a first opposing flat surface on a male attachment member and a first ball is biased into the first detent.

First claim

What is claimed is:

1. A treatment assembly for securing a treatment member to a shaft, the treatment assembly comprising:
the treatment member, wherein the treatment member defines a longitudinal axis and has a distal end and a proximal end, wherein the proximal end includes an attachment recess defined therein,
a female attachment member having a distal end, a proximal end, and a shaft recess defined in the proximal end, wherein the female attachment member is secured in the attachment recess of the treatment member, wherein the shaft recess is defined by an interior surface that includes first and second opposing flat surfaces, wherein the first flat surface includes a first detent defined therein and the second flat surface includes a second detent defined therein, whereby when the shaft is received in the shaft recess, the first flat surface is operatively engaged with a first opposing flat surface on a male attachment member and a first ball is biased into the first detent and the second flat surface is operatively engaged with a second opposing flat surface on a male attachment member and a second ball is biased into the second detent.

2. The treatment assembly of claim 1 wherein the interior surface includes first and second opposing curved surfaces.

3. The treatment assembly of claim 2 wherein the first and second flat surfaces of the female attachment member are substantially parallel to one another.

4. An attachment system for securing a treatment member to a shaft, the attachment system comprising:
the treatment member, wherein the treatment member defines a longitudinal axis and has a distal end and a proximal end, wherein the proximal end includes an attachment recess defined therein,
a female attachment member having a distal end, a proximal end, and a shaft recess defined in the proximal end, wherein the female attachment member is secured in the attachment recess of the treatment member, wherein the shaft recess is defined by an interior surface that includes first and second opposing flat surfaces, wherein the first flat surface includes a first detent defined therein and the second flat surface includes a second detent defined therein,
a male attachment member disposed in the shaft recess, wherein the male attachment member includes an exterior surface with first and second opposing flat surfaces, wherein a first ball is biased outwardly from the first flat surface and a second ball is biased outwardly from the second flat surface,
wherein the first flat surface of the female attachment member is operatively engaged with the first flat surface of the male attachment member and the first ball is biased into the first detent, and wherein the second flat surface of the female attachment member is operatively engaged with the second flat surface of the male attachment member and the second ball is biased into the second detent.

5. The attachment system of claim 4 wherein the interior surface of the female attachment member includes first and second opposing curved surfaces, wherein the exterior surface of the male attachment member includes first and second opposing curved surfaces.

6. The attachment system of claim 5 wherein the first and second flat surfaces of the female attachment member are substantially parallel to one another and the first and second opposing flat surfaces of the male attachment member are substantially parallel to one another.

7. The attachment system of claim 6 wherein the male attachment member includes an inclined surface on a distal end thereof.
