Description

[0001] ENDOSCOPIC OPERATION DEVICE [0002]

The present invention relates to an instrument for endoscopic surgery, and more particularly, to an instrument for endoscopic surgery that minimizes interference between surgical instruments and facilitates operation.

In general, peritoneal and thoracic endoscopic surgery is a procedure in which a small hole is made in the body of the patient and the inside of the body is observed through the hole. The operation is performed through general surgery such as cholecystectomy, appendectomy, It is widely used in the field of thoracic surgery such as renal cystectomy, renal resection, stones removal, urology surgery and gynecologic surgery, partial resection of the lung, lung resection, and mediastinal tumor resection.

These endoscopic operations can be classified into multiport surgery and singlet port surgery.

Multi-port surgery involves the insertion of a trocar into each hole, the insertion of a surgical instrument such as an endoscope, a gas injector, an electrician, forceps, and a cutter into each trocar one-to-one And the operation is performed while observing the inside of the patient. Such a multiport surgery is disadvantageous in that it causes a lot of scars to be generated in the patient's body by making multiple holes in the patient's body.

 In addition, single-port surgery is performed by perforating a single hole in a patient's body. However, it is advantageous that the scar can be minimized compared to conventional endoscopic surgery. However, since the operation method is not easy, There is a disadvantage that experience is required. The reason for this is that it is necessary to perform surgery in a state where a plurality of surgical instruments are inserted in a single space, so that it is difficult to perform operations other than the expert ones due to interference between the surgical instruments in the surgical procedure, so that at least one trocar is additionally required.

1 is a perspective view of a surgical device used in a single-port operation according to the prior art. Referring to FIG. 1, an insertion port 110, cannula 120 is shown. A plurality of insertion ports (110) into which a surgical instrument is inserted are formed in protrusions formed on the trocar. Also, since the cannula 120 is formed in a shape of a lumen, and each insertion port 110 is connected to a different internal pipe, the surgical instrument inserted into the different insertion port 110 is inserted only in a predetermined path.

According to the related art, the protrusion formed with the insertion port 110 has a problem that a cover having a large radius is engaged and frequently collides with the cover of another adjacent protrusion. Especially, since the interval between the surgical instruments is narrow, This is a disadvantage.
