Description

  The present invention relates to a surgical organ adsorbing device for adsorbing and supporting a patient's organ in thoracoscopic surgery and laparoscopic surgery.

  Conventionally, normal forceps have been used to raise and shift the lungs and mediastinal organs, such as when performing lung resection in thoracoscopic surgery. However, there is a risk of damaging or crushing organs and tumors, and it may be difficult to lift and shift the position.

  For this purpose, various suction and support devices have been developed in order to raise and shift the position of organs in the operative field. In Patent Document 1, for example, as a forceps that can be accurately grasped without causing damage to an organ and without slipping, a forceps attached to the tip of the forceps and lifted by suction is used to prevent organ damage. Is disclosed. However, in the invention disclosed in this publication, the suction cup at the tip of the forceps is small and is not suitable for lifting the lung (about 500 g on one side).

  Further, as an instrument for aspirating and supporting an organ, for example, in a heart surgery, an instrument called a positioner for raising the heart and an instrument called a stabilizer for reducing pulsation vibration have been used conventionally. . However, neither instrument can be inserted into the thoracic cavity or mediastinum through a hole between ribs.
