A method of manufacturing a jaw for an electrosurgical instrument comprises providing a jaw housing and an electrically conductive plate or sealing electrode 1. The plate is placed into a mould and a first flowable insulating material 15 is injected into the mould, so that the material forms one or more stop members 16 projecting a predetermined distance from the plate. The jaw housing and the plate are then placed into a second mould and a second flowable material is injected into the mould to secure the plate to the jaw housing. The method may include a step of providing a pre-moulded insert that can be received within the jaw housing, where the plate may be placed against the insert to form a sub-assembly before placing the sub-assembly into the first mould. The plate may comprise one or more passages or holes 8, where the first flowable material flows through the holes to form the one-or-more stop members. The plate may have an elongated groove 7 in which the holes are located. The plate may comprise a longitudinally extending slot capable of receiving a translatable knife blade. Also disclosed a method of manufacturing an end-effector for sealing tissue. |
