Benefits of technology

"The invention is a tonsil forceps that can be opened and closed like scissors to grasp and release a tonsil. The forceps have two intersecting arm members that are joined by a pivoting connection at an intermediate point. The forceps can be locked in different positions to securely hold the tonsil. The forceps have finger loops and grasping means with curved surfaces and tine members that are interdigitized when the forceps are fully closed. The forceps also have blunt projection members and flush lateral projection members that do not contact each other when the forceps are fully closed. The technical effects of the invention include improved grip, secure locking, and reduced risk of injury during use."

Problems solved by technology

Often the tonsils are partially embedded within the muscles and fascia, such that grasping the tonsil is difficult.
The current style forceps used for this task tend to bite, stab or cut the tonsil during this grasping operation, resulting in undesirable fragmentation of the tonsil during the resection.

Embodiment Construction

[0021]With reference to the drawings, the invention will now be described in detail with regard for the best mode and the preferred embodiment. In a most general sense, the invention is a tonsil forceps for grasping or pulling a tonsil so as to separate it from the surrounding mucosa, muscle and fascia, the structure of the grasping means being such that the tonsil is cradled rather than stabbed or cut by the grasping means during removal, and therefore remains intact as opposed to being fragmented during the resection procedure. The tonsil forceps may be realized in various embodiments.

[0022]A first embodiment of the tonsil forceps is illustrated in FIGS. 1 through 6. The tonsil forceps comprise a first intersecting arm member 11 and a second intersecting arm member 12, each having a distal end 13 and a proximal end 14. The arm members 11 and 12 are connected by means 20 for pivoting the arm members 11 and 12, such that the distal ends 13 of the arm members 11 and 12 can be closed ...

Abstract

A tonsil forceps having first and second intersecting and pivoting arm members, releasable locking members for securing the forceps in multiple positions and grasping members disposed on said arm members. In at least one of the locked positions, the tines on the grasping members do not cross. The grasping members have a concave interior surface, inwardly facing blunt interior projection members, flush lateral projection members and angled lateral projection members. The projecting members are non-contacting with each other even in the maximum closed forceps position.

Description

[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 12 / 381,901, filed Mar. 18, 2009, claiming the benefit of U.S. Provisional Patent Application Ser. No. 61 / 069,942, filed Mar. 18, 2008.BACKGROUND OF THE INVENTION[0002]This invention relates generally to the field of medical forceps, and more particularly to such forceps that are lockable in multiple indexed closure positions and that possess distal end finger-like projections.[0003]Forceps are handheld instruments in the form of tongs or pincers used to grasp, compress or pull body parts, tissue, organs, teeth, etc. A typical forceps comprises a pair of pivotally joined elongated arm members, the proximal ends of the arms being provided with finger holes for manipulating the instrument and the distal ends being provided with grasping structures suited for particular purposes, such as finger-like extensions, sharp teeth, blades, curved members, concave members, etc. Many forceps are provided with rel...
