Tissue fixing device in laparoscopy

Abstract

The invention discloses a tissue fixing device in laparoscopy. The tissue fixing device comprises a device body, a holding handle, a tissue fixing claw, fixing and supporting pressing plates, a lithium battery pack and a cylinder. The holding handle is connected with the top of the device body. The fixing and supporting pressing plates are arranged on the two sides of the middle of the device body. The tops of the fixing and supporting pressing plates are electrically connected with the lithium battery pack. The inner side end of each fixing and supporting pressing plate is electrically connected with an installing shaft. A heating resistance wire is electrically connected into each fixing and supporting pressing plate. A rubber cushion is attached to the bottom of each fixing and supporting pressing plate. NTC temperature sensors are distributed at the inner side bottom of each fixing and supporting pressing plate. A connecting shaft is arranged in the middle of the device body. The outer end of the supporting rod is connected with the tissue fixing claw through a first rotating shaft gear. The tissue fixing device in laparoscopy has the function of grabbing, fixing or blocking a certain part of tissue, has the main function of fixing in-vivo tissue organs, and is beneficial for exposing the view in the operation process and reducing accidental injuries.

Description

technical field [0001] The invention relates to the technical field of laparoscopic surgery, in particular to a tissue fixation device in laparoscopic surgery. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. The laparoscopic operation method is to make three to five small incisions of 0.5-1.0 cm in the patient's abdomen, and respectively insert "trocar" (a kind of pipeline-like working channel that runs through the abdominal wall and connects the inside and outside of the abdominal cavity) w...

Problems solved by technology

[0003] Existing laparoscopic instruments have a wide variety of functions such as grasping, fixing, cutting, suturing, electrocoagulation, electrocutting, etc., and their applications are becoming more and more mature. However, it requires the operator and assistants to cooperate accurately in multiple directions, and sometimes requires one person to complete the operation with both hands at the same time. Multiple parts are grasped, fixed and pushed, or both hands are simultaneously used to assist grasping, fixed and pushing, and the other hand is used to separate and coagulate, etc. There are often still two people with insufficient coordination of both hands, smooth or irregular tissues, slipping of the grasping parts, Possibility of accidental injury, synchronous multi-position grasping and fixing for a long time at the same time, excessive strain on the operator's shoulders, arms, waist, etc., may cause functional decline, etc. Now there is a need for an instrument that can achieve functional improvement and strengthening in terms of fixing and pushing tissues and organs. , efficient, labor-saving, the object of the present invention is to realize this need
