PROBLEM TO BE SOLVED: To provide improved alternatives to methods of manufacturing jaw members for electrosurgical instruments by an overmolding process in which components are incorporated into a mold and a flowable material is introduced into the mold to surround the components and form the completed jaw members.SOLUTION: A jaw member for an electrosurgical instrument is manufactured by providing a jaw housing 18 having a longitudinal jaw section, and an electrically conductive plate 1. The electrically conductive plate 1 is placed in a mold, and a first flowable insulating material is injected into the mold such that the flowable material forms one or more stop members that project by a predetermined distance from the electrically conductive plate 1. The jaw housing 18 and the electrically conductive plate 1 are then placed in a second mold, and a second flowable material 25 is injected into the mold to secure the electrically conductive plate 1 to the jaw housing 18.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2016,JPO&INPIT【課題】構成部品を型に組み入れ、型に導入した流動性の材料で構成部品を取り囲んで完成顎部材を形成するオーバーモールド成形プロセスによって電気手術器具用の顎部材を製造する方法に対する改良代替案を提供する。【解決手段】電気手術器具の顎部材が、長手方向の顎区間を有する顎ハウジング18と導電性プレート1とを提供するステップによって製造される。導電性プレート1を型内に置き、第1の流動性の絶縁材料が導電性プレート1から所定距離突出する1以上の止め部材を形成するように、流動性の材料を型に注入する。次に、顎ハウジング18と導電性プレート1とを第2の型内に置き、第2の流動性の材料25を型に注入して導電性プレート1を顎ハウジング18に固定させる。【選択図】図9
