Abstract
A retaining member for a surgical instrument insert is described. The instrument insert includes a retaining member which is free to move along the shaft before the insert is attached to the handle. The retaining member comprises a resilient member integrally formed with the retaining member. The resilient member can engage the surgical instrument insert shaft and act to prevent the retaining member falling off before the insert is attached to the handle. Because the resilient member is integrally formed the cost of manufacture is reduced. In another embodiment, a surgical instrument insert is provided wherein a proximal portion of the outer shaft is manufactured from an insulating material. The insulating material can be cheaper than the aluminum conventionally used. As a further advantage this also reduces the risk of electric shock and bums when used in an electrically live environment.
