Definitions

  • the present invention relates to a medical trocar, and more particularly to a thoracic trocar.
  • a trocar is a device that supports the operation of the thoracic or abdominal cavity by making a small hole without making a large incision in the abdomen or thoracic cavity of the patient.
  • Medical trocars are generally medical instruments used to access the thoracic or abdominal cavity. Medical instruments such as laparoscopic, thoracoscopic, and endoscope are inserted using a medical trocar.
  • Thoracoscopic surgery is a method of drilling a small hole in the patient's thoracic cavity and through this hole while observing the inside of the thoracic cavity.
  • thoracoscopic surgery has been developed to make the incision of the skin as small as possible, and the operation using this thoracoscopic surgery is increasing day by day.
  • the trocar is inserted between the ribs and ribs in the same region as the thorax to observe organs such as the lungs or to perform surgery. It causes tremendous pain, which still causes great pain after surgery.
  • An object of the present invention is to provide a thoracic trocar for reducing the pain of the patient when the trocar is inserted between the bones, such as the chest.
  • One embodiment of the present invention is a trocar for thoracic cavity, trocar; Cannula; And a shield, wherein the trocar is divided into upper and lower parts, the lower part is a cylindrical member, the upper part is a member having a size larger than the circumference of the lower cylinder, and the lower end which does not contact the upper part is tapered (the cannula includes a tubular member insertable along the longitudinal direction of a cylinder at the bottom of the trocar and a portion of the tubular member widened at one end of the tubular member.
  • the cannula is inserted into the trocar so that the widening portion faces the upper side of the trocar, and the shield is a tubular member that wraps around its length along the length of the tubular cannula of the cannula.
  • the shield is a tubular member that wraps around its length along the length of the tubular cannula of the cannula.
  • the shield is also referred to as an insertion member, and in the present specification, the shield is a uniform shield. Threads may be formed on the outside of the shield.
  • the tubular member of the cannula is made of a rigid plastic material (for example, plastic such as PC, PP, ABS, etc.), and the shield is made of a flexible and soft material (eg, a plastic).
