Abstract
A locking tonsil forceps having first and second intersecting and pivoting arm members, and grasping members disposed on the arm members. The grasping members have blunt tine members, a concave interior surface, inwardly facing blunt interior projection members, flush lateral projection members and angled lateral projection members. The tine members and projecting members are non-contacting with each other even in the maximum closed forceps position.

A tonsil forceps comprising:
- a first intersecting arm member and a second intersecting arm member, each having a distal end and a proximal end, said arm members being joined by pivoting connection means defining a pivot plane, such that said distal ends can be closed and opened by bringing together or spreading apart said arm member proximal ends in a scissor-like manner, said distal ends of said arm members extending out of said pivot plane such that each said arm member has a concave side and a convex side;
- a finger loop positioned at said proximal end of each said arm member;
- means for temporarily locking said forceps in a fixed position;
- each said first and said second arm members comprising a tonsil grasping member, each said grasping member comprising an interior surface bounded by a convex-side lateral edge and a concave-side lateral edge, tine members positioned on said distal end and extending around onto said convex-side lateral edge of each grasping member, tine gaps disposed between said tine members, inwardly facing, interior projection members positioned on each of said interior surfaces, and projection gaps disposed between said interior projection members;
- wherein said tine members of said first arm member are positioned opposite from said tine gaps of said second arm member and said tine members of said second arm member are positioned opposite said tine gaps of said first arm member, such that said tine members do not contact each other when said forceps are closed;
- wherein said interior projection members of said first arm member are positioned opposite from said projection gaps of said second arm member and said interior projection members of said second arm member are positioned opposite said projection gaps of said first arm member, such that said interior projection members do not contact each other when said forceps are closed;
- and
- each said grasping member further comprising at least one flush lateral projection member disposed on or adjacent said concave-side lateral edge and at least one angled lateral projection member disposed on or adjacent said convex-side lateral edge, whereby said at least one flush lateral projection member is flush with said concave side and said at least one angled projection member extends outwardly from said convex side.
