Endoscopic device having spray mechanism and related methods of use

Abstract

Various embodiments of a surgical device that combines tissue cutting and spraying in a single device and related methods of use are disclosed. The device may include an elongated member having a proximal end and a distal end, an end effector proximate the distal end of the elongated member, and a nozzle member configured to substantially seal the distal end of the elongated member. The nozzle member may define a flow path in fluid communication between inside and outside of the elongated member when the distal end of the elongated member is sealed with the nozzle member.

         4 . The endoscopic device of  claim 1 , wherein the nozzle member has a base portion and a head portion, and wherein the base portion has an outer diameter that is less than an inner diameter of the tubular member. 
     
     
         5 . The endoscopic device of  claim 1 , wherein the nozzle member includes a proximal seal that is configured to seal against the tubular member. 
     
     
         6 . The endoscopic device of  claim 1 , wherein the handle includes a thumb ring and a movable member. 
     
     
         7 . The endoscopic device of  claim 1 , wherein the handle includes a fluid connector that is configured to be coupled to a fluid source. 
     
     
         8 . The endoscopic device of  claim 7 , wherein the fluid source includes a syringe. 
     
     
         9 . The endoscopic device of  claim 1 , wherein a distal portion of the handle includes a fluid chamber for storing fluid. 
     
     
         10 . The endoscopic device of  claim 1 , wherein the handle includes an electrical connector. 
     
     
         11 . The endoscopic device of  claim 1 , wherein the control member is a single filament wire. 
     
     
         12 . The endoscopic device of  claim 1 , wherein the control member is a multifilament wire. 
     
     
         13 . The endoscopic device of  claim 1 , wherein the snare loop is coupled to the control member with a crimp ring. 
     
     
         14 . An endoscopic device, comprising:
 a tubular member;   a control member extending through the tubular member;   a snare loop coupled to a distal end of the control member, the snare loop having a distal tip;   wherein the snare loop is configured to shift between a first configuration where the snare loop is disposed in the tubular member and a second configuration where the snare loop is disposed distally of a distal end of the tubular member; and   a nozzle member attached to the distal tip, the nozzle member defining a fluid pathway therethrough.   
     
     
         15 . The endoscopic device of  claim 14 , wherein the nozzle member defines a plurality of fluid flow paths therethrough. 
     
     
         16 . The endoscopic device of  claim 14 , wherein the nozzle member has a base portion and a head portion, and wherein the base portion has an outer diameter that is less than an inner diameter of the tubular member. 
     
     
         17 . The endoscopic device of  claim 14 , wherein the nozzle member has a base portion that is configured to seal against the tubular member. 
     
     
         18 . The endoscopic device of  claim 17 , wherein the base portion is sealed against the tubular member when the snare loop is in the first configuration. 
     
     
         19 . The endoscopic device of  claim 14 , wherein a handle is attached to the tubular member, the handle having a fluid connector that is configured to connect with a fluid source. 
     
     
         20 . An endoscopic device, comprising:
 a tubular member having a proximal end, a distal end, and a lumen extending therebetween;   a control member extending through the lumen;   wherein a snare loop is disposed at a distal end of the control member;   wherein the snare loop is configured to shift between a first configuration where the snare loop is disposed in the tubular member and a second configuration where the snare loop is disposed distally of the distal end of the tubular member;   a handle coupled to the tubular member;   wherein the handle includes an actuation mechanism that is configured to shift the snare loop between the first configuration and the second configuration;   a nozzle member attached to the snare loop, the nozzle member defining a fluid pathway therethrough; and   wherein the nozzle member includes base portion that is configured to seal against the tubular member when the snare loop is in the first configuration.
