Retraction device for laparoscopy

摘要

Disclosed herein is a retraction device for laparoscopy in which a trocar needle including latching grooves formed at the side of the lower end thereof is inserted into a trocar tube, both ends of which are opened, to form a laparoscopic platform, the laparoscopic platform pierces an abdominal wall and the trocar needle is pushed into an abdominal cavity so that the latching grooves are exposed to the outside of the trocar tube, sutures connected to tissue retractors retracting tissues are hung on the latching grooves, and then the trocar needle of the laparoscopic platform is drawn upwards so that the latching grooves are inserted back into the trocar tube to fix the tissue retractors to the laparoscopic platform. The retraction device for laparoscopy prevents the tissues from being unnecessarily damaged due to retraction and facilitates convenient retraction of the tissues without the help of assistant's two hands.

主权项

1. A retraction device for laparoscopy, comprising:
a pair of clamps including interface surfaces having prominence and depression shapes corresponding to each other, the pair of clamps being formed at left and right forceps parts to form fixing forceps; and a tap type retractor including a tap attached to an end of a suture having a needle, the tap having a top flat circular surface configured to support a tissue, a side circumferential surface connected to the top circular surface, and a cone shaped bottom surface connected to the side surface, wherein the needle of the tap type retractor is configured to penetrate one side of a tissue so that the tap is configured to be supported by an outer wall of the tissue, the needle having penetrated the tissue is configured to pass through an abdominal wall and to exit an abdominal cavity, the suture of the tap type retractor is configured to be inserted between the interface surfaces of the clamps of the fixing forceps being configured to be located on an upper surface of the abdominal wall, and then the clamps are configured to be moved towards each other to firmly fix the tap type retractor.
