US 4,091,815 A · Flexible tube clamp

Abstract

The disclosure is directed to a clamp for flexible tube and more particularly a clamp for surgical use. The clamp is formed of plastic material and has a pair of clamping members connected by a flexible hinge. The flexible hinge biases the clamping members open and a cam with at least one elongated handle closes the clamping members about a flexible tube or vessel. The clamp may be locked by a screw threaded through the cam and which is advanceable into contact with one clamping member. The clamping members are provided with beveled edges to define narrow convex clamping surfaces for the concentrated distribution of the clamping force, and the surfaces have serrations to prevent slippage of the tube from the grasp of the clamp. The clamping members may be curved to facilitate insertion of the clamp into inaccessible body areas during surgical applications.

Dependent claims

A clamp comprising:

first and second clamping members having cooperating clamping surfaces;
hinge means connecting said clamping members at one end thereof;
a pair of posts secured to said first clamping member;
rotatable cam means eccentrically mounted on a shaft pivotally retained by said posts and having a curved cam surface portion which may be rotated into contact with said second clamping member for urging said clamping members together to a closed position, and said cam means further having a flat cam surface portion extending from and trailing said curved surface portion, which may be rotated into contact with said second clamping member to prevent free rotation of the cam when the clamping members are in the closed position;
a screw threaded into said cam and
advanceable through said curved cam surface portion into contact with said second clamping member to secure said clamping members in the closed position.
