Abstract

Handheld forceps comprising: a body comprising trunk and a first arm and a second arm extending from a base of the trunk coupled at one end and separated from one another at a second end; a rod disposed in the body, the rod comprising a first end positioned in the first arm and a second end positioned in the second arm and forming an apex in the trunk; a compression spring disposed around the apex of the rod in the trunk; and a button coupled to the apex of the rod and protruding through an opening in the trunk. Also a method of using the handheld forceps.

First claim

What is claimed is:

1. Handheld forceps comprising:
a body comprising trunk and a first arm and a second arm extending from a base of the trunk coupled at one end and separated from one another at a second end;
a rod disposed in the body, the rod comprising a first end positioned in the first arm and a second end positioned in the second arm and forming an apex in the trunk;
a compression spring disposed around the apex of the rod in the trunk; and
a button coupled to the apex of the rod and protruding through an opening in the trunk.

2. The handheld forceps of claim 1 , wherein the trunk comprises a volume therein defined by the opening at its end and a shelf, wherein one end of the compression spring contacts the shelf and wherein the button is disposed around the spring.

3. The handheld forceps of claim 1 , wherein the rod has a first position wherein the first end and the second end are operable with the arms to accept a tip on the end of the respective first end and respective second end and a second position operable to separate the tip from the respective first end or second end.

4. The handheld forceps of claim 3 , wherein in the second position, the first end and the second end of the rod are disposed a greater distance from a respective end of the first arm and the second arm.

5. The handheld forceps of claim 3 , wherein the rod is operable to move from the first position to the second position by the depression of the button toward the opening in the trunk.

6. The handheld forceps of claim 3 , wherein the rod is biased to the first position by the compression spring.

7. A method of using handheld forceps of claim 1 , comprising:
pushing a first tip onto the first arm and a second tip onto the second arm of the body; and
depressing the button to cause the rod to move the first tip off of the first arm and the second tip off of the second arm.
