Abstract

A system and method for coordinated and controlled abdominal gas insufflation includes clamp configured to engage an abdominal wall. A needle advancement control is configured to receive a needle and advance the needle toward the clamp to extend into a portion of the abdomen. A feedback device is configured to monitor the needle as it is advanced into the portion of the abdomen of the subject and provide feedback indicating that the needle has pierced the portion the abdomen.

First claim

What is claimed is:

1. A system for guiding a needle into an abdomen of a subject, the system comprising:
a clamping system including a first clamp arranged in opposition to a second clamp, the first clamp and second clamp being rotatably coupled to a hinge and rotatable about the hinge between a first closed position and a second open position by rotating at least one handle about the hinge;
a needle advancement control configured to receive a needle and advance the needle toward the first clamp and the second clamp to extend therebetween and into a portion of the abdomen of the subject when arranged between the first clamp and the second clamp; and
a feedback device configured to monitor the needle as it is advanced into the portion of the abdomen of the subject and provide feedback indicating that the needle has pierced the portion the abdomen.

2. The system of claim 1 wherein the feedback device includes at least one of an auditory and a visual feedback indicator.

3. The system of claim 1 wherein the feedback device includes a sensor configured to monitor at least one of the needle advancement control and needle to determine when the needle has pierced the portion of abdomen.

4. The system of claim 3 wherein the sensor includes a torque sensor configured to monitor a torque associated with the needle advancement control to advance the needle.

5. The system of claim 1 wherein the needle advancement control device further comprises:
a needle guide path; and
an actuation device for driving the needle through the needle guide path.

6. The system of claim 5 further comprising a locking mechanism configured to lock the needle relative to the guide path.

7. The system of claim 1 further comprising a motor configured to advance and retract the needle relative to the first and second clamp.

8. The system of claim 1 further comprising an insufflations source configured to be coupled to the needle to deliver a gas to the abdomen of the subject through the needle.

9. The system of claim 1 wherein the needle control system includes a controller programmed to coordinate advancement of the needle along the needle guide path and delivery of the gas through the needle.

10. A system for delivering an insufflations gas to an abdomen of a patient, the system comprising:
a clamp system configured to engage and lift an abdominal wall of a patient, the clamp system including a first clamp and a second clamp opposing the first clamp to engage opposing sides of the abdominal wall of a patient, the first clamp and second clamp coupled to one another and rotatable about a common axis, the first clamp having a first handle and the second clamp having a second handle, the first handle and the second handle rotatable about the common axis to move the first clamp and the second clamp between a first closed position and a second open position, the clamp system including a needle guide path directing into the abdominal wall of the patient;
a needle arranged within the needle guide path;
an insufflator coupled to the needle to deliver a gas along the needle and through the abdominal wall of the patient; and
a needle control system configured to control advancement of the needle along the needle guide path and into the abdomen wall of the patient.

11. The system of claim 10 wherein the needle advancement system translates rotational movement into linear advancement of the needle along the needle guide path.

12. The system of claim 10 wherein the needle advancement system includes a motor configured to drive the needle along the needle guide path.

13. The system of claim 10 further comprising a single handle system configured to cause the needle control system to advance the needle and delivery of the gas from the insufflator.

14. The system of claim 10 further comprising at least one sensor configured to monitor at least one of the needle control system and the needle to determine when the needle has pierced the abdomen wall.

15. The system of claim 14 wherein the at least one sensor includes a torque sensor.

16. The system of claim 10 wherein the clamp system includes jaws pivotally connected to move between a closed position and an open position using a single hand.

17. A kit for delivering an insufflations gas to an abdomen of a patient, the kit comprising:
a diagnostic device configured to analyze the abdomen of the patient and provide feedback upon detecting a pool of blood;
a clamp system having two opposing clamps coupled to a hinge that are configured to engage and lift an abdominal wall of a patient by angularly displacing a handle about the hinge, the handle being coupled to one of the two opposing clamps, the clamp system further including a needle guide path directing into the abdominal wall of the patient;
a needle arranged within the needle guide path;
an insufflator coupled to the needle to deliver a gas along the needle and through the abdominal wall of the patient; and
a needle control system configured to control advancement of the needle along the needle guide path and into the abdominal wall of the patient.

18. The kit of claim 17 , wherein the diagnostic device is configured to deliver ultrasound waves into the abdomen of the patient and receive waves in response to the delivery of the ultrasound waves to detect the pool of blood.

19. The kit of claim 17 further comprising a single handle configured to control the clamp system, insufflator, and needle control system.

20. The kit of claim 17 further comprising at least one sensor configured to monitor at least one of the needle control system and the needle to detect indications that the needle has penetrated the abdominal wall of the patient and a controller configured to coordinate operation of the clamp system, needle control system, and insufflator.

21. A system for guiding a needle into an abdomen of a subject, the system comprising:
a clamping system including a first lever and a second lever rotatable about a pivot pin to move a first clamp and a second clamp between a first closed position and a second open position, the pivot pin extending transversely across the first lever and the second lever, wherein the first lever is formed with a first handle and the first clamp and the second lever is formed with a second handle and the second clamp opposing the first clamp;
a needle advancement control configured to receive a needle and advance the needle toward the first clamp and the second clamp to extend therebetween and into a portion of the abdomen of the subject when arranged between the first clamp and the second clamp; and
a feedback device configured to monitor the needle as it is advanced into the portion of the abdomen of the subject and provide feedback indicating that the needle has pierced the portion of the abdomen.

22. The system of claim 21 , wherein the pivot pin extends transversely across the first lever between the first handle and the first clamp and across the second lever between the second handle and the second clamp.

23. The system of claim 21 , wherein a plurality of teeth are formed in the first lever and the second lever, the plurality of teeth being spaced apart to receive a plate that engages and locks with the teeth to secure the first lever and the second lever in the second open position.

24. The system of claim 21 , wherein the needle advancement control is coupled to at least one of the first lever and the second lever at a location
