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 trocar needle including latching grooves formed at a side of a lower end thereof and configured to be inserted into a trocar tube, wherein both ends of the trocar tube are opened to form a laparoscopic platform, the laparoscopic platform is configured to pierce an abdominal wall, the trocar needle is configured to be pushed into an abdominal cavity, and the latching grooves are exposed to the outside of the trocar tube; and at least one suture provided with a needle connected to at least one tissue retractor configured for retracting tissues and configured to be hung on the latching grooves, wherein the trocar needle is configured to be drawn upwards so that the latching grooves are configured to be inserted back into the trocar tube to fix the tissue retractors to the laparoscopic platform, wherein the at least one tissue retractor includes: a tap type retractor in which a tap is attached to one end of the at least one suture provided with a needle; and a band type retractor including a toothed part with latching protrusions arranged in a line and formed at one end of a band-shaped main body, and an insertion hole formed at another end of the band-shaped main body, wherein each of the latching protrusions is configured to be inserted into the insertion hole, wherein the band type retractor further includes connection holes respectively formed on the latching protrusions of the toothed part so that the tap type retractor is configured to be connected to the connection holes, and the tap type retractor is configured to be connected to the band type retractor by allowing the needle of the tap type retractor to pass through one of the connection holes and the tap to be supported by an outer surface of one of the latching protrusions.
