Abstract

The present invention is directed toward devices and methods for use in minimally invasive needlescopic procedures whereby an improved bowel grasper incorporates a means for measuring the pressure applied to a body part is translated to a visual representation. In addition, in an embodiment a rubberized bowel grasper device having a chevron style surface which is used to facilitate grabbing and manipulating body parts is provided. In another embodiment of the present invention and system a device and method for measuring distances inside the abdomen is provided. Further embodiments include bowel graspers with a combination of the above features and functions.

Claims

1. A multifunction surgical instrument comprising a laparoscopic grasper jaw and at least one of:

a laparoscopic length measuring tool;

a tissue grasper having rubberized jaws;

or

a gauge which provides visual indication of the pressure being applied by the tissue grasper upon tissue clamped between the rubberized jaws.

2. The multifunction surgical instrument claim 1, wherein:

the gauge includes an element which, when the jaws are in a maximally closed but spaced and locked position with tissue grasped therebetween, the gauge is activated to visually indicate whether pressure applied to the tissue is within a predetermined acceptable range, allowing for adjustment of the pressure.

3. The multifunction surgical instrument claim 1, further comprising:

an inner grasper movement controller shaft and an outer shaft for securing the tissue grasper in position, wherein the pressure readings provided by the gauge are translated to linear movements of the inner grasper movement controller shaft relative to the outer shaft.

4. The multifunction surgical instrument claim 3, wherein:

pressure produced by an outer movable finger holder of the surgical instrument, which engages and controls a housing of the surgical instrument in a manner wherein a spring within the housing seated about the outer shaft and against a spring retainer stop, is measured by the gauge.

5. The multifunction surgical instrument claim 4, wherein:

the spring retainer stop causes a shaft of the visual indicator to rotate to a position indicative of a particular pressure being applied, the housing moving proximally and causing the shaft to turn via engagement to the proximal end of the spring.

6. The multifunction surgical instrument claim 5, wherein:

the rotating shaft mounts a gear which moves along a rack assembly of the housing which causes the rotation of the shaft which in turn causes a rotational movement of the visual indicator to apprise of a particular predetermined pressure associated with the rotational position of the shaft.

7. The multifunction surgical instrument claim 1, further comprising:

a bowel measurement tool having a measuring string which is wound around a shaft of the tool and incorporates a proximal end loop which is engaged to pull the string proximally outward.

8. The multifunction surgical instrument of claim 7, wherein:

the measurement tool is operable such that the measurement tool remains stationary while the string is being pulled to a desired location and the string spins within a helical groove or recess around the shaft as the string is pulled to a desired length position.

9. The multifunction surgical instrument of claim 8, wherein:

the string of the bowel measurement tool includes a color-coded measuring scheme.

10. The multifunction surgical instrument of claim 1, wherein:

the rubberized jaws of the tissue grasper have a rubberized material forming a grasping surface of the jaws.

11. The multifunction surgical instrument of claim 1, wherein:

the rubberized jaws have a chevron surface pattern.

12. The multifunction surgical instrument of claim 1, wherein:

the surgical instrument is configured for use in intestinal and gallbladder laparoscopic procedures.

13. The multifunction surgical instrument of claim 10, wherein:

frictional openings are provided along a length of the grasper jaws for frictional engaging the rubberized material.

14. A multifunction surgical instrument for use in laparoscopic surgery, comprising:

at least one or more of a laparoscopic measuring tool, a tissue grasper having rubberized jaws, and a gauge which provides a visual indication of pressure being applied by the tissue grasper to tissue clamped between the rubberized jaws.
