Trocar system for use in laparoscopic surgery

Abstract

The present invention relates to a trocar system for use in laparoscopic surgery, which prevents improper suturing caused as a result of the point of a suture needle being shaken when suturing a peritoneal hole of the peritoneum after completion of laparoscopic surgery and, more specifically, to a trocar system for use in laparoscopic surgery, comprising: a suture needle guide member which has interconnected through-holes formed at the outer surface thereof, and first and second suture needle guide holes formed on the periphery of the through-holes at opposite sides of the outer surface, respectively, and having an elongated form in the length direction at a slant; a trocar which is detachably coupled to the suture needle guide member, passes through the through-holes, has a space formed therein, and has, at one outer side passing through the through-holes, third and fourth suture needle guide holes facing the first and second suture needle guide holes, respectively, and formed to pass through the space, and fifth and sixth suture needle guide holes facing the first and second suture needle guide holes, respectively, and formed at the opposite one outer side that does not pass through the through-holes; a trocar unit to which the suture needle guide member is detachably coupled and which has, formed at the outer side, a through-hole through which the trocar coupled with the suture needle guide member passes, and has, at one outer side close to the one side of the trocar passing through the through-hole, seventh and eighth suture needle guide holes facing the third and fourth suture needle guide holes, respectively; and a suture needle which is guided into the first, third, fifth, and seventh suture needle guide holes and the second, fourth, sixth, and eighth guide holes and provided with suture thread, wherein the trocar coupled with the suture needle guide member and the trocar unit to which the suture needle guide member is coupled are inserted into the abdominal cavity of the human body to penetrate the peritoneum and form a peritoneal hole, and when laparoscopic surgery with an endoscope and surgical instruments, which are inserted into the abdominal cavity of the human body through the through-holes while the trocar is separated from the suture needle guide member, is completed, the endoscope and surgical instruments are removed from the through-holes, and thereafter the trocar is coupled to the suture needle guide member to guide the suture needle into the first, third, fifth, and seventh suture needle guide holes and the second, fourth, sixth, and eighth suture needle guide holes to suture the peritoneal hole with the suture thread.

Description

technical field [0001] The invention relates to a trocar system for laparoscopic surgery. In particular, it relates to a trocar system for laparoscopic surgery that prevents the focus of a suturing needle from being unable to suture normally when suturing a peritoneal hole of the peritoneum after the laparoscopic surgery. Background technique [0002] Generally speaking, laparoscopic surgery is different from the existing laparotomy. In this surgical method, 4 to 6 holes of about 0.5 to 1.2 cm are made in the abdomen, and then 0.5 to 1.2 cm in diameter are inserted into the holes. A puncture device (trocar) with a length of 15-16 cm, and then put a light source and a camera into the hole, and put various surgical tools through another hole, so that while observing the external monitor (monitor), The organs are cut and then stitched into shape. [0003] In addition, in order to perform laparoscopic surgery, a trocar (trocar) is first inserted into the patient's abdomen, and...

Problems solved by technology

[0006] However, according to Patent Document 1, since the suture needle cannot be guided and caught in the hole-shaped first opening with a wide area, the focus of the suture needle may be shaken.

[0007] In addition, due to the groove-shaped second opening that is long in the longitudinal direction, the focal point of the suture needle may be shaken.

[0008] That is, the needle penetrates too close to the peritoneal hole in the peritoneum, possibly causing the hole to be torn
