Definitions

  • the present invention relates to an opening device insertion device for easily inserting an opening device into an incision in the body.
  • MIS minimally invasive surgery
  • an opening device for example, a wound retractor
  • a single port is used by combining it with the opening device.
  • the opening device protects the inner surface of the incision window from contact with surgical tools or surgical extracts and serves as a passage for surgical tools to enter and exit.
  • the wound retractor used as an opening device in single-hole laparoscopic surgery includes a cylindrical tube and a pair of shape-retaining rings provided at both ends of the cylindrical tube to maintain the original shape of both ends of the cylindrical tube.
  • One end of the shape-retaining ring of the umbilical retractor is inserted into the abdomen, and the other end is placed outside the abdomen, so that the cylindrical tube forms a passage in the umbilicus.
  • Single-hole laparoscopic surgery begins by inserting one shape-retaining ring into the abdomen through a small incision in the belly button. Making a large incision in the navel makes it easier to insert an opening device, but because the incision in the patient's navel is so large, it leaves a lot of pain and scars after the surgery. Therefore, in single-hole laparoscopic surgery, it is necessary to minimize the size of the incision window.
  • the present invention was created to solve the above-mentioned problems, and the purpose of the present invention is to minimize the size of the body incision and provide an opening device insertion device that can easily insert the opening device into small or deep body incisions. .
  • An opening device insertion device for solving the above-described problems includes an insertion guide that forms a channel in which a trocar or an opening device is accommodated and is drawn in and out of an incision wound of the body; And a guide part that is cut in the insertion guide to communicate with the channel along the longitudinal direction of the insertion guide, and guides the opening mechanism accommodated in the channel of the insertion guide to be spaced apart from the insertion guide.
  • a cut is formed extending from the guide portion toward the distal portion of the insertion guide, and the distal portion of the fenestration tool accommodated in the channel is inserted so that the fenestration device accommodated in the channel is separated from the insertion guide through the guide portion. It may further include a guide part that guides the guide away from the guide.
  • the guide portion may have a cross-sectional shape in which the cut cross-sectional area increases as it moves from the proximal portion of the insertion guide to the distal portion of the insertion guide.
  • it may further include a pusher that pushes the opening mechanism toward the channel so that the opening mechanism is inserted into the channel of the insertion guide.
  • the pusher may include a pusher body having a diameter corresponding to the channel; And it may further include a handle for holding the pusher body.
  • a fixing groove formed in any one of the trocar and the insertion guide may further include a fixing protrusion formed on the other one of the trocar and the insertion guide and inserted into the fixing groove.
  • the opening mechanism may include an elastically deformable wound retractor.
  • the insertion guide may be made of a transparent material.
  • the device for inserting an opening device has the effect of minimizing the size of an incision in the body and easily inserting an opening device into a narrow or deep incision in the body.
