Description

[0001] APPARATUS FOR LAPAROSCOPIC SURGERY AND WOUND RETRACTOR ASSEMBLY [0002]

The present invention relates to a laparoscopic surgical apparatus and a cloud tractor assembly, and more particularly, to a laparoscopic surgical apparatus and a cloud tractor assembly, which can be used to penetrate a laparoscopic surgical instrument, will be.

Unlike conventional laparotomy, laparoscopic surgery is being performed to minimize the incision of the skin and to restore the patient 's speed.

Such a laparoscopic operation is a surgical procedure performed by observing the operation site of the abdominal cavity by making a tube to the abdomen of the patient using a surgical apparatus called Trocar and introducing a surgical instrument such as an endoscope into a surgical site in the abdominal cavity, Resection, biliary stones removal, head dendriticectomy, general surgery and so on.

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. Thus, conventionally, a surgical assistant (eg, a nurse) pulls the incision directly, spreads the inside or outside of the incision with a forceps, connects the wire to the forceps, pulls it around the instrument and binds the incision to secure a surgical space in the abdomen Surgery was performed.

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.

In the case of laparoscopic surgery using a trocar, the surgical tube is inserted into the incision and the surgical instrument is inserted into the abdomen through the tube, so that the surgical instrument is not likely to come into contact with the wound tissue of the incision. However, A conventional incision is made by making one incision in the incision and wrapping the inside and the outside of the incision with vinyl or the like and then removing the excision to prevent the excision from contacting the incision wound tissue.

However, in the conventional surgical method, a plurality of incisions have to be formed. In order to solve such a problem, Korean Patent No. 10-102754 (Announcement: Mar. 17, 2011) Quot; multi-channel trocar that combines a multi-channel trocar ", and a cut-off portion of the abdomen is provided with a multi-channel 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 instrument, moves the inserted surgical instrument, The same operation space is secured, and the wound tissue of the incision is wrapped to prevent the cancer cells from being transferred to the wound tissue.

In the case of a multi-channel trolley according to Korean Patent No. 10-1022754, there is an advantage that the can retractor can be detachably coupled and assembled to the main body, but the structure of the can retractor is complicated, There is a problem that the unit price is increased and the operation of combining the multi-channel member for trocar with the can retractor is complicated. Particularly, since the multi-channel member for trocar is made rigid, it is difficult to attach the can retractor to the multi- There is a problem.

As another prior art, Korean Patent Registration No. 10-1172660 (public announcement: August 08, 2012) discloses a "laparoscopic wound re-tractor", and specifically discloses an upper retractor and a shape retention member And a lower body coupled to a lower end of the penetration tube, wherein the upper body is located outside the incision, and the lower body is located inside the incision, , And the penetration tube forms a passage.

In addition, Korean Patent No. 10-1172660 discloses a laparoscopic surgeon who can easily secure an operation space at the time of laparoscopic surgery, and can easily carry out operations such as extraction of the exudates without infection .

As another prior art, Korean Patent No. 10-1468169 filed by the applicant of the present invention and registered in Korean Patent Registration No. 10-1468169 (announcement date: Dec. 12, 2014) discloses a "winter retractor", specifically, A lower ring member located on the inner side of the incision, and a sleeve of a soft elastic body connecting the upper ring member and the upper ring member to the upper ring member located outside the incision, wherein the upper ring member comprises a circular or elliptical And a coupling protrusion formed on the outer circumferential surface of the first shape retaining body in a longitudinal direction; And a second shape retaining member formed in a circular or elliptic cross section filled with a hollow and having an engaging groove for engaging with and engaging with an engaging projection on the outer circumferential surface of the second shape retaining member, The end portions of the first shape retaining member and the second shape retaining member are bonded with each other in an abutted state, so that the upper ring member is entirely circular, and accordingly, the can retractor can be easily manufactured and the grip feeling can be improved , And can be manufactured in various sizes.

However, in order to facilitate the use of the wound retractor in the laparoscopic surgery, it should be used in combination with a means such as a channel device disclosed in Korean Patent No. 10-1468169, A clearance may be generated between the retractor and the channel device.
