Description

Single port {SINGLE PORT}

The present invention relates to a single port, and more particularly, to a single port for preventing contamination around a laparoscopic surgical environment.

In general, unlike conventional open surgery, laparoscopic surgery is being performed to minimize the incision of the skin and to allow the patient to recover quickly. Laparoscopic surgery refers to the surgical procedure performed by observing the surgical site of the abdominal cavity by creating a tube to the abdomen of the patient using a surgical instrument called Trocar and introducing a surgical instrument such as an endoscope into the surgical site within the abdominal cavity.

Such laparoscopic surgery has been widely used for cholecystectomy, biliary stones removal, prolapse surgery, and general surgery. Here, the trocar refers to a medical instrument used for approaching the abdominal cavity, and the trocar is inserted and fixed into the body through a navel or a skin incision (incision) of a patient, and a structure in which a laparoscopic surgical instrument is inserted To be exposed to the outside. Through the incision of the abdomen, the surgical instruments for surgery can be inserted, as well as the exudates (organs, lumps, cancer tissues, etc.) generated during surgery can be taken out. The smaller the incision is made, the less space is available for surgery. Therefore, in conventional laparoscopic surgery, a surgical assistant (eg, a nurse) pulls the incision directly or pulls it apart, or the inside and the outside of the incision are tied with a forceps and the wire is connected to the tongue. The operation space was secured. Such a conventional method of opening the incision is troublesome and has a problem of limiting the activity space of a doctor. Since the incision cuts the abdominal skin tissue, it is necessary to prevent the exudate from contacting the wound tissue of the incision or contact with the surgical instrument in the case of surgery that involves secondary infection (metastasis), such as cancer tissue removal surgery. As described above, there is a problem in that a surgical incision to open the incision requires the formation of a plurality of incisions.

Accordingly, Korean Patent Registration No. 10-1022754 (published on Mar. 17, 2011) discloses a "multi-channel trocar having a can retractor" for solving the above-mentioned problem, And a multi-channel member is coupled to an upper portion of the can retractor. Here, the wound retractor, which is a device used in laparoscopic surgery, opens the incision for abdominal surgery without restricting the physician's activity space, and inserts the surgical space such as insertion of the surgical instrument, movement of the inserted surgical instrument, The laparoscopic surgery using the above-described wound retractor and the like can be used to prevent contamination of the inside of the body during laparoscopic surgery, Gas is directly discharged to the outside, there is a problem that the environment surrounding the laparoscopic surgery is contaminated. In addition, the conventional single port according to the prior art requires only one or two cameras and a mechanism to be inserted in the circle. However, if the gas injection tube is installed in the inside, it may get caught in the apparatus and may interfere with the operation.
