摘要： A method and apparatus for ligating tissue is disclosed. The applicator utilizes a jaw portion having jaw members with jaw faces to grasp tissue and operating portions to apply a surgical clip. In a presently preferred embodiment, the surgical clip utilized is a self-closing clip. Operating faces in the operating portion of the jaw members separate the clip from the tissue prior to clip installation. The applicator has a channel in the operating portion for user viewing which also may allow for lateral displacement of a clip external to the jaw faces.
摘要翻译：公开了一种用于结扎组织的方法和装置。施用器使用具有钳口构件的钳口部分，其具有钳口面以抓住组织和操作部分以施加手术夹。在目前优选的实施例中，所使用的手术夹是自闭合夹。钳夹构件的操作部分中的操作面在夹子安装之前将夹子与组织分开。施加器在用于观察的操作部分中具有通道，其还可以允许夹钳外部的夹子的横向移位。

摘要： A trocar is formed from a cannula and an interfitting obturator for penetrating body cavity walls in laparoscopic and endoscopic surgery. The obturator is provided with an improved piercing tip having a pointed blade and an improved locking shield design. The locking mechanism must be actuated before the shield will retract to expose the piercing tip. The shield is located inside the obturator sheath and provides faster coverage of the piercing tip after the body cavity wall has been penetrated. The cannula has an improved thread design to more easily and securely hold the cannula in the incision of the body cavity wall. A one piece inner housing is used in the cannula to reduce the need for welding to prevent gas leakage. The cannula also has improved seals to maintain insufflation of the body cavity and an automatic insufflation valve to facilitate connection to an external gas supply. Reducing fittings may also be used on the cannula to allow the insertion of endoscopic instruments of lesser diameter than the obturator.
摘要翻译：套管针由腹腔镜和内窥镜手术中的插管和用于穿透体腔壁的相互配合的闭孔器形成。封闭器设置有具有尖锐刀片和改进的锁定屏蔽设计的改进的刺穿尖端。必须先锁定机构，然后才能使护罩缩回以露出刺孔。护罩位于闭孔护套内，并且在体腔壁被穿透之后提供更快的穿刺尖端覆盖。套管具有改进的螺纹设计，以更容易且牢固地将套管保持在体腔壁的切口中。在套管中使用一体式内壳，以减少焊接的需要，以防止气体泄漏。套管还具有改进的密封件以保持体腔吹气和自动吹入阀，以便于连接到外部气体供应。也可以在套管上使用减压配件，以允许插入直径小于闭孔器的内窥镜器械。

摘要： A novel reducer system is provided for a trocar cannula. The reducer system fastens to the cannula end and a living hinge allows a reducer cap to be closed over the cannula lumen to allow the cannula to be used with smaller diameter surgical instruments. By fastening the reducer system to the exterior of the cannula end, the system can be placed in position on the cannula prior to surgery, even while a large diameter obturator is used with the cannula.
摘要翻译：为套管针插管提供了一种新颖的减速器系统。减速器系统紧固到套管端部，并且活动铰链允许将减速器盖封闭在套管内腔上，以允许套管与较小直径的外科器械一起使用。通过将减速器系统紧固到套管端部的外部，即使在与插管一起使用大直径闭塞器的情况下，也可以在手术之前将系统放置在套管上的适当位置。

摘要： A novel, bipolar, electrosurgical instrument is provided with one metal and one ceramic end effector. Current is passed through the metal end effector and through an insulated conduit to the distal tip of the ceramic end effector. A connection at the distal tip of the ceramic end effector allows the current to return along exposed conductive strip which is spaced apart from the metal end effector in cutting action by a gap of approximately 0.020 inches when the ceramic and metal blade supports are brought into contact with tissue, a current flows from the exposed metal strip on the ceramic blade through to the metal blade thereby effecting cauterization, preferably slightly in advance or at the point of cutting between the ceramic and metal blades.
