Problems solved by technology

Although applying higher clamping forces on the tissue favors the efficiency of the inflation and drying periods of the tissue sealing process, high clamping forces during the denaturation and fusion periods of the tissue sealing process tend to promote tissue adhesion to the jaw members

Embodiment Construction

[0025] Specific embodiments of the present disclosure are described below with reference to the drawings, in which like reference numerals indicate like or corresponding elements in each of the several views. As used herein, the term "distal" refers to the part of the system, device and / or components thereof that is further from the user, while the term "proximal" refers to the part of the system, device and / or components thereof that is closer to the user part. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the disclosure with unnecessary detail.

[0026] Surgical systems according to the present invention may include endoscopic and / or open surgical instruments, such as forceps devices, ultrasonic dissection devices, and / or any other suitable surgical devices. Obviously, different electrical and mechanical connections and considerations apply to each specific type of device, however, the various aspects and ...

Abstract

The present invention provides a pliers including a pair of jaw members, a drive tube coupled to the pair of jaw members, and a spring assembly positioned at a proximal end of the drive tube. The drive tube is movable to pivot one or both of the pair of jaw members between a spaced apart position and an approximated position. The spring assembly is configured to engage the drive tube and limit movement of the drive tube to control relative motion between the pair of jaw members.

Description

technical field [0001] The present disclosure relates to forceps, and more particularly, to forceps for controlling forceps during a tissue sealing procedure. Background technique [0002] Energy-based medical devices are typically used in conjunction with an energy source (either a portable energy source incorporated within the device itself or an external energy source) to apply energy to tissue and to control the application of energy to thermally treat (e.g., heat) tissue to thereby To achieve the desired organizational effect. Energy-based surgical forceps, for example, utilize both the mechanical clamping action of the jaw members and the energy provided by the energy source and delivered to the tissue to heat the tissue clamped between the jaw members to achieve a desired tissue effect , such as sealing the tissue. [0003] Once the tissue is clamped between the jaw members, tissue sealing typically involves heating the clamped tissue during a period of aeration and...
