Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tissue extraction apparatus for laparoscopic surgery, and more particularly, to a structure capable of simultaneously inserting a tissue extraction device and a laparoscopic surgical instrument through a single trocar.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tissue extraction apparatus for laparoscopic surgery, and more particularly, to a pouch used for extracting a tissue cut out from a laparoscopic surgical procedure and an instrument used for manipulating the pouch in the abdominal cavity.
Laparoscopic Surgery is a surgical procedure in which a surgical instrument is inserted into the abdominal cavity through several small incisions on the human body, minimizing the wound caused by surgery, unlike conventional laparotomy, You can do it fast. Such laparoscopic surgery is also referred to as Minimally Invasive Surgery or Endoscopic Surgery.
Laparoscopic surgery is commonly used in surgery to remove and remove some or all of the tissues or organs in the body. For example, they are used for nephrectomy, cholecystectomy, duodenectomy, jejunectomy, myomectomy, and the like, and the application range is gradually expanding.
In a laparoscopic surgical procedure, a resected human tissue or organ (hereinafter, referred to as "tissue") is contained in a translucent pouch made of a synthetic resin and is extracorporeally extracted through the incision of the human body. Tissue pouches provide the ability to prevent the ablated tissue from infecting or damaging surrounding organs during withdrawal. These pouches are sometimes referred to as "endo-bags" or "lap-bags". These pouches form part of a tissue extraction device with instruments for manipulating them. The tissue extraction device is composed of an elastic member for opening the pouch entrance, a tube for storing the elastic member and the pouch inserted therein, and an operation rod for pushing the pouch out of the tube to unfold the inside of the abdominal cavity do.
Laparoscopic surgery is performed with insertion of a trocar into 3 or 4 incisions. The trocar injects gas (eg, carbon dioxide) into the abdomen to inflate to form a space in which the surgical instruments can move and allows the surgeon to gain visibility. The trocar also provides a passage for inserting various instruments for surgery, such as an endoscopy camera, scissors, forceps, stapler, and the like. In surgery for resection of the human body, at least three trocar must be inserted into the human body so that the endoscope camera, the surgical instrument, and the tissue extraction device can be individually inserted, and three or more incisions must be formed for this purpose. Tracer insertion of a tissue extraction device has been a factor in increasing the number of incisions in the human body since it could not be used to insert other surgical instruments. The incision formed in the human body for insertion of the trocar can leave a wound on the patient, which may increase the recovery period after surgery and increase the risk of infection during surgery. Also, as the number of trocar used increased, the complexity of surgery increased and the number of medical personnel required for surgery increased.
In addition to the above-mentioned problems, the conventional tissue extracting apparatus has a problem in that productivity is low because the time required for curing the adhesive in the assembling process becomes long due to the bonding of the elastic member and the operating rod by the bonding method using the adhesive. Further, there is a problem that the assembly method using an adhesive has a high risk of deformation or breakage due to changes in the physical properties of the material at the bonding site over a long period of time.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to improve the structure of a conventional tissue extraction device and to further insert a surgical instrument into a trocar into which a tissue extraction device is inserted, thereby reducing the number of incisions required for laparoscopic surgery And to provide a laparoscopic surgical tissue extraction apparatus capable of performing laparoscopic surgery.
Another object of the present invention is to provide a tissue extraction apparatus for laparoscopic surgery, which provides a structure that can be assembled without using an adhesive, thereby shortening the assembly time and improving productivity.
It is another object of the present invention to provide a tissue extraction apparatus for laparoscopic surgery that is simple in configuration and easy to use.
