Abstract: Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.

Abstract: A laparoscopic scissor instrument can include a scissor assembly pivotally coupled to an elongate shaft. The scissor assembly can be formed of scissor blades having pivot posts thereon. The pivot posts can engage apertures on the elongate shaft, thus eliminating the need for a through-pinned pivot connection of the scissor blades. The scissor blades can also include actuation posts thereon. An actuation mechanism can include a slot to engage the actuation posts and open or close the blades of the scissor assembly. The scissor assemblies described herein can have a relatively low operational height such that they do not extend beyond a diameter of the elongate shaft during opening and closing of the scissor assembly.

Abstract translation: 腹腔镜剪刀器械可以包括枢转地联接到细长轴的剪刀组件。 剪刀组件可以由其上具有枢轴柱的剪刀片形成。 枢轴柱可以接合细长轴上的孔，从而消除了对剪刀叶片的通过销钉的枢转连接的需要。 剪刀刀片还可以包括其上的致动柱。 致动机构可以包括用于接合致动柱并且打开或关闭剪刀组件的叶片的槽。 本文所述的剪刀组件可以具有相对较低的操作高度，使得它们在打开和关闭剪刀组件期间不延伸超过细长轴的直径。
