Embodiment Construction

[0038] The present disclosure provides energy-based surgical devices and systems that facilitate the breakdown of tissue within an internal body cavity to enable its removal from the internal body cavity.

[0039] go to figure 1 , shows an energy-based surgical device 100 generally comprising a proximal hub 110 , an elongated outer tube 120 , an active electrode assembly 130 and a return electrode assembly 140 provided in accordance with the present disclosure. The energy-based surgical device 100 is described in detail below. Additional reference figure 2 The energy-based surgical device 100 together with the obturator 200 and the gripping hook 300 provides a surgical system 1000 configured to facilitate the breakdown of tissue within an internal body cavity to enable its removal from the internal body cavity. The obturator 200 and the holding hook 300 are also described in detail below.

[0040] continue to refer figure 1 and figure 2, surgical system 1000 is configur...

Abstract

The invention relates to an energy-based surgical device and system facilitating tissue removal. The energy-based surgical device includes an elongated outer tube having a distal overhang, a proximalhub, a distal cutting member, and a flat spring. The distal cutting member has a U-shaped cutting edge and defines a mouth with the distal overhang extending therethrough. The flat spring includes a first portion extending distally along an exterior surface of the elongated outer tube and the distal overhang, a second portion extending from the first portion and bent over a free distal end of thedistal overhang, and a third portion extending from the second portion proximally through the mouth of the distal cutting member and into the lumen of the elongated outer tube and traverses a majorityof a diameter thereof. The distal cutting member and flat spring are adapted to connect to a source for electrosurgical energy for conducting bipolar energy through tissue disposed therebetween to cut tissue.

Description

technical field [0001] The present disclosure relates to tissue removal, and more particularly, to energy-based surgical devices and systems that facilitate disintegration of tissue to enable its removal from internal body cavities. Background technique [0002] In minimally invasive surgery, surgery is performed inside an internal body cavity through small openings in the body. The entrance can be a natural passage of the body, or it can be created surgically, for example by making a small incision through which a cannula is inserted. [0003] Minimally invasive surgery may be used to partially or completely remove tissue from an internal body cavity. However, the limited access provided by minimally invasive openings (natural access and / or surgically created openings) presents challenges in large tissue removal. As a result, tissue that is considered too large to be removed intact is broken down into multiple smaller pieces, allowing it to be removed from the internal bo...
