Device for use in laparoscopic surgery and method of use

Abstract

A device for use in laparoscopic surgery is provided. The device has a plurality of telescoping sections positioned in and movable relative to a protective sheath between an extended configuration, wherein a body section of a first one of the telescoping sections is spaced apart from a body section of a second one of the telescoping sections, and a retracted configuration wherein the body section of the first one of the telescoping sections is in contact with the body section of the second one of the telescoping sections. A tissue interaction portion is configured to interact with tissue in response to the manipulation of a device actuator.

What is claimed is: 
     
         1 . A device for use in laparoscopic surgery, comprising:
 a distal end having a tissue interaction portion;   a proximal end having a device actuator;   a protective sheath having a distal end and a proximal end and extending at least partially between the tissue interaction portion and the device actuator;   a plurality of telescoping sections positioned in and movable relative to the protective sheath between an extended configuration, wherein a body section of a first one of the telescoping sections is spaced apart from a body section of a second one of the telescoping sections, and a retracted configuration wherein the body section of the first one of the telescoping sections is in contact with the body section of the second one of the telescoping sections; wherein   the plurality of telescoping sections are movable from the extended configuration in response to a manipulation of the device actuator; and   the tissue interaction portion is configured to interact with tissue in response to the manipulation of the device actuator.   
     
     
         2 . The device of  claim 1 , wherein
 the tissue interaction portion comprises at least one of a gripping mechanism, a clamping section, a coupling mechanism, or a cutting mechanism.   
     
     
         3 . The device of  claim 2 , wherein
 the at least one of the gripping mechanism, the clamping section, the coupling mechanism, or the cutting mechanism is configured to interact with tissue in response to the manipulation of the device actuator.   
     
     
         4 . The device of  claim 1 , wherein:
 the device actuator comprises a rod configured to move the telescoping sections in response to the manipulation.   
     
     
         5 . The device of  claim 4 , further comprising:
 a cutting mechanism; and   at least one staple pusher positioned in the protective sheath; wherein   the at least one staple pusher is translatable in response to translation of the rod; and wherein   the rod is further configured to move the cutting mechanism ( 640 ).   
     
     
         6 . The device of  claim 5 , wherein
 the at least one staple pusher comprises a raised leading section and a raised following section configured to enable distal and proximal movement of the at least one staple pusher in response to distal and proximal movement of the rod; and   the cutting mechanism comprises a raised following section, whereby movement of the cutting mechanism is delayed relative to movement of the at least one staple pusher.   
     
     
         7 . The device of  claim 1 , further comprising:
 a cutting mechanism positioned in the protective sheath and slidable relative to the protective sheath and through a lower section slot in at least one of the plurality of telescoping sections.   
     
     
         8 . The device of  claim 7 , wherein:
 the first one of the plurality of telescoping sections further comprises an attachment section; and   the second one of the plurality of telescoping sections further comprises a body section notch adapted to slidably receive the attachment section of the first one of the plurality of telescoping sections; whereby   the first one and the second one of the plurality of telescoping sections remain coupled in the extended configuration and the retracted configuration.   
     
     
         9 . The device of  claim 8 , wherein
 the protective sheath, the attachment section, and the body section notch are adapted to limit the plurality of telescoping sections to sliding motion.   
     
     
         10 . The device of  claim 8 , wherein
 the device actuator comprises a rod configured to move the telescoping sections in response to the manipulation,   the rod, the attachment section and the body section notch are adapted to enable movement from the retracted configuration to the extended configuration in response to a second manipulation of the device actuator.   
     
     
         11 . The device of  claim 1 , further comprising:
 at least one of a locking sheath or a clamping sheath configured to limit the device to a single use.
