Laparoscopic stapler

A laparoscopic stapler comprising:

• a body configured to fire an inserted implant toward a target portion;
• a through-passage providing part coupled to a front distal end of the body, and comprising a through-passage, wherein the implant fired from the body is configured to move through the through-passage toward the target portion;
• and
• a rear extension part coupled to a back distal end of the body, and configured to support an operation rod,
• wherein the body comprises:
• a passage, wherein the implant fired from the body is configured to move through the passage toward the through-passage;
• and
• a space, wherein the operation rod configured to perform linear movement, and
• wherein the body further includes:
• a first body part;
• and
• a second body part configured to be gripped by a user, and
• wherein the first body part comprises:
• an implant assembly insertion passage formed on an upper side of the first body part such that an implant assembly, in which the implant and an implant support that supports the implant are coupled to each other is vertically inserted;
• a pin housing part configured to provide a space, in which a through-needle bunch part that feeds the implant to insert the implant into the target portion is vertically moved;
• an implant assembly aligning part formed adjacent to an area, in which a rear end of the pin housing part and the implant assembly cross each other, and configured to align the implant assembly;
• and
• an operation rod pressing member coupled to a portion of the operation rod disposed at a rear end of the through-needle bunch part while extending on a line together with the through-needle bunch part, and configured to transmit power for the linear movement of the operation rod.
