Methods for intra-abdominally moving and holding the liver away from the stomach
View Patent ↗An apparatus including a flexible length of cord and three tissue connectors positioned at the opposite ends of the cord and at an intermediate position of the cord is designed to be laparoscopically inserted through the abdominal wall and into the abdominal cavity, and used to move a first internal organ to a position away from a second internal organ where the apparatus holds the first internal organ in the position without further manual input, thereby providing surgical access to the second internal organ.
1. A method of moving a first body tissue comprising a liver of a patient to a position away from a second body tissue comprising a stomach of the patient and then holding the liver at the position, the method comprising:
providing a first cord segment having a flexible length with opposite first and second ends and a second cord segment having a flexible length with opposite first and second ends;
providing a first tissue connector that is attached to the first end of the first cord segment;
providing a second tissue connector that is attached to the first end of the second cord segment;
providing a third tissue connector that is attached to the second end of the first cord segment and is attached to the second end of the second cord segment;
inserting the first and second cord segments and the first second and third tissue connectors into an area containing the liver and stomach;
connecting the second end of the first cord segment to a third body tissue adjacent the liver by attaching the third tissue connector to the third body tissue and connecting the first end of the first cord segment to a fourth body tissue that is on an opposite side of the area containing the liver and stomach from the third body tissue by attaching the first tissue connector to the fourth body tissue with the length of the first cord segment extending across and moving the liver toward the position away from the stomach;
connecting the second end of the second cord segment to the third body tissue adjacent the liver by attaching the third tissue connector to the third body tissue and connecting the first end of the second cord segment to a fifth body tissue that is on an opposite side of the area containing the liver and stomach from the third body tissue by attaching the second tissue connector to the fifth body tissue with the length of the second cord segment; and
engaging across and moving the liver toward the position away from the stomach;
whereby the first and second cord segments engaging across the liver hold the liver at the position away from the stomach without manual input.
2. The method of claim 1 further comprising the steps of:
providing at least one of the first, second or third tissue connector in the form of a tissue connector comprising a J-hook locking clasp.
3. The method of claim 1 further comprising the steps of:
providing at least one of the first, second or third tissue connector in the form of a tissue connector further comprising a clutch mechanism operable to allow the cord segment secured to the tissue connector to be pulled through the clutch mechanism in a first direction and prevented by the clutch mechanism from being pulled in a second direction opposite the first direction.
4. A method of moving, within the abdomen of a patient, the liver of the patient to a position away from the stomach of the patient and then holding the liver, said method comprising:
inserting into the abdomen of the patient a device comprising a cord having first and second ends, a first connector secured to the cord at the first end of the cord, and a second connector secured to the cord at a mid-point between the first end and the second end, and a third connector secured to the cord at the second end of the cord, thereby defining a first cord segment between the first and second tissue connectors and a second cord segment between the second and third tissue connectors;
securing the second connector to the diaphragm crus of the patient, thereby securing a midpoint of the cord to the diaphragm crus of the patient;
passing the first cord segment and second cord segment between the liver and the stomach
securing the first tissue connector to the abdominal wall, and securing the third tissue connector to the abdominal wall, whereby the first and second cord segments engage the liver to hold the liver at the position away from the stomach.
5. The method of claim 4 , further comprising:
disconnecting the second tissue connector from the diaphragm crus of the patient, and disconnecting the first tissue connector from the abdominal wall, and disconnecting the third tissue connector from the abdominal wall; and removing the device from the abdomen.
6. The method of claim 4 further comprising the steps of:
providing at least one of the first, second or third tissue connector in the form of a tissue connector comprising a J-hook locking clasp.
7. The method of claim 4 further comprising the steps of:
providing at least one of the first, second or third tissue connector in the form of a tissue connector further comprising a clutch mechanism operable to allow the cord segment secured to the tissue connector to be pulled through the clutch mechanism in a first direction and prevented by the clutch mechanism from being pulled in a second direction opposite the first direction.
8. A method of moving, within the abdomen of a patient, the liver of the patient to a position away from the stomach of the patient and then holding the liver, said method comprising:
inserting into the abdomen of the patient a device comprising a first cord segment and a second cord segment, each having first and second ends, a first connector secured to the first cord segment at the first end of the first cord segment, and a second connector secured to the second ends of both the first cord segment and the second cord segment, and a third connector secured to the second cord segment at the first end of the second cord segment;
securing the second connector to the diaphragm crus of the patient, thereby securing the second ends of both the first cord segment and the second cord segment to the diaphragm crus of the patient;
passing the first cord segment and second cord segment between liver and the stomach;
securing the first tissue connector to the abdominal wall, and securing the third tissue connector to the abdominal wall, whereby the first and second cord segments engage the liver to hold the liver at the position away from the stomach.
9. The method of claim 8 , further comprising:
disconnecting the second tissue connector from the diaphragm crus of the patient, and disconnecting the first tissue connector from the abdominal wall, and disconnecting the third tissue connector from the abdominal wall; and removing the device from the abdomen.
10. The method of claim 8 further comprising the steps of:
providing at least one of the first, second or third tissue connector in the form of a tissue connector comprising a J-hook locking clasp.
11. The method of claim 8 further comprising the steps of:
providing at least one of the first, second or third tissue connector in the form of a tissue connector further comprising a clutch mechanism operable to allow the cord segment secured to the tissue connector to be pulled through the clutch mechanism in a first direction and prevented by the clutch mechanism from being pulled in a second direction opposite the first direction.
