Abstract

Parallel arms 11 have symmetrically paired projections 12 on their inner sides. In use the projections assist the picking up of cotton wool objects. Preferably the forceps are of a plastics material, and are discarded after use. <IMAGE>

Description

TITLE: AN ANTISLIP DISPOSABLE FORCEPS BACKGROUND OF THE INVENTION The medical apparatus that are commonly used, more particularly for oral cavity treatment, are mainly made of stainless steel in one integral unit. However, in modern times, some viruses such as AIDS are not easily killed by regular sterilizing equipment. Therefore, some disposallle-tip and totally disposable medical instruments have come into use, because of demand.

During the installation or removal procedure for disposable-tip type instruments, the original handle portion of the instrument may still be contaminated.

This, there is a stl'ong demand among otolaryngological surgeons for a disposable plastic forceps to replace the conventional stainless steel product. However, in comparison with a stainless steel forceps, the plastic forceps has inferior rigidity. Therefore, while using a plastic forceps to clamp sponges, pads and the like formed of cotton wool, it is difficult to pick up the cotton wool objects and they can easily slip from the forceps.

SUMMARY OF THE INVENT ION An antislip disposable forceps for use in holding an object formed of cotton wool is provided. The forceps includes a substantially parallel pair of longitudinally extended clamping arms. The two clamping arms being coupled together at one end of the forceps. The forceps also includes at least two pairs of tooth-like projections. Each pair of projections extending from an opposing inner surface of each of the claml)i.ng arms. The projections being positionally located at the distal end of the clamping arms.Each projection of one pair of projections are positionally aligned with a respective projection of the other pair of projections for securely holding te cotton wool oh,jlvet with the forceps.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side and front plane view of the disposable forceps.

DESCRIPTION OF THE PREFERRED EMBODIRNTS Referring to FIG. 1, the two clamping arms 11 of the forceps 1 are joined at one end and are specially designed to respectively provide two symmetric tooth like projections, or noses, 12 integrally formed on the iner wall of each clamping arm 11. The projections are formed in relatively close proximity to the bend at the distal end of each clamping arm 11, about 5 m.m.

from the bend. The tooth-like noses 12 of each clamping arm 11 are arranged such that they extend toward one another from opposing clamping arms. The teeth 'a' and 'b' and the teeth 'a' and 'b' are arranged longitudinally, such that the upper tooth 'a' engages the correxponding upper tooth 'a', and the lower tooth 'b' engages the lower tooth 'b' to tightly pinch an object formed of cotton wool when the two clamping arms are pressed toward one another.

This invention also sets a horizontal stick (13) on the fit position of clamping arm 11, for preventing from remove of the forceps 1, and getting best spring for the two clamping arm 11.

In general, as described above, the invention is to provide an nntislip and disposable forceps, formed from plastic, for medical use. The forceps comprises two paris of tooth-like projections, or noses, respectively arranged adjacent the distal bend of each clamping arm to engage with each other. The opposing projections prevent the clamped object from slipping away. Thu, the invention provides a simple structure. having a good clamping effect, and is economical to produce. The disposability of the forceps prevents the transmission of disease from one patient to another.

Claims

WHAT IS CLAIMED IS:

1. An nntislip disposable forceps for use in holding an object formed of cotton wool, comprising: a substantially parallel pair of longitudinally extended clamping arms, said clamping arms being coupled one to the other at. one end of said forceps: and, at least two pairs of toothy-like projections, each pair of projections extending from an opposing inner surface of each of said clamping arms at a distal end thereof, each projection of one of said pair of projections being positionally aligned with a respective projection of said other pair of projections for securely holding said object with said forceps.

2. According claim 1 an antislip disposable forceps set, among, sets a horizontal stick on the fit position of clampirlt arms to contact the clamping arms to contact t.llc clamping arms of two forces, preventing the front clamp part, of forceps from slipping away for operation, and getting best spring for clamping arm in order to operate.
