Problems solved by technology

[0003] However, tissue sealing instruments that include blades and blade pockets are typically single-use devices because the blades and blade pockets can be difficult to clean, and the blades can wear and dull with repeated use

Embodiment Construction

[0040] In this disclosure, the term "proximal" refers to the part of a structure that is closer to the operator, while the term "distal" refers to the part of the same structure that is further from the operator. As used herein, the term "subject" refers to a human patient or an animal. The term "operator" refers to physicians (eg, surgeons), nurses, and other clinicians or medical personnel and may include support personnel. The terms "substantially", "approximately" and "approximately" are to be understood as words of approximation, taking into account that the correction factor is relatively small or unchanged (eg, by less than 3%). Terms of reference such as "horizontal," "vertical," "upper," "lower," "above," "beneath," etc. are intended to simplify the description of the embodiments and are not intended to be definitive of the surgical instrument or any portion thereof. Orientation imposes no restrictions.

Abstract

The invention relates to a pair of electric forceps for surgeries, comprising a terminal actuator. The terminal actuator comprises a first jaw component with a first tissue contact surface and a second jaw component with a second tissue contact surface. Both the first jaw and the second jaw are provided with a cutting edge at the side parts of the first tissue contact surface and the second tissue contact surface. The forceps are structured to selectively transmit electric energy between the first tissue contact surface of the first jaw component and the second tissue contact surface of the second jaw component. At least one of the two jaw components is able to move among the opening position, a first approaching position and a second approaching position of the other. In the first approaching position, the first tissue contact surface and the second tissue contact surface almost face each other and are mutually aligned. In the second approaching position, the first tissue contact surface and the second tissue contact surface are not aligned.

Description

technical field [0001] The present disclosure relates to energy-based surgical instruments, and more particularly, to energy-based surgical forceps configured for manipulating and / or cutting tissue. Background technique [0002] Forceps or hemostats are pincer-like instruments that rely on mechanical action between their jaws to grasp, hold and restrain tissue. Energy-based forceps utilize mechanical grasping action and energy, such as electrosurgical energy, ultrasonic energy, light energy, microwave energy, heat, etc., to achieve hemostasis by heating tissue to coagulate and / or cauterize it. Certain surgical procedures call for simpler cauterization of tissue and rely on a specific combination of clamping pressure, precise energy control, and gap distance (i.e., the distance between opposing jaws when closed around tissue) to "seal" the tissue . Typically, once the tissue is sealed, the surgeon must accurately dissect the tissue along the newly formed tissue seal. Accor...
