Abstract
Abstract A surgical device for effecting temporary sterilisation of females by binding the Fallopian tubes is described, which instrument comprises a barrel and an implement at the distal end thereof and which can be operated from the proximal end thereof. In accordance with the invention, the implement referred to consists of a pair of grips which have arms openable and closable and curved so as to be able to surround a Fallopian tube: a passage is provided through the barrel to receive a binding element such as a thread or other filament, or a strip, and this binding element passes through the gripping arms when they are in their normally closed state. Preferably, although not necessarily, the passage referred to begins and ends in the proximal section of the instrument.
