Material delivery surgical device

Abstract

Medical devices for injecting materials into patients are disclosed. The devices can include a body having a handle and a lever. The devices can also include a delivery tube comprising a passageway along a longitudinal axis and a nozzle with an opening, the delivery tube configured to couple with a distal end of the body. A driving rod can be inserted into the body and extend into the passageway, such that the lever can move the driving rod distally when the lever is actuated toward the handle. Methods of using the material delivery device are also disclosed.

What is claimed is: 
     
         1 . A device for injecting materials into a patient, the device comprising:
 a body comprising a handle, a lever, a collar and a cavity inside the body;   a delivery tube comprising a passageway along a longitudinal axis and a nozzle with a lateral opening, the delivery tube configured to releasably couple to the collar at a distal end of the body; and   a driving rod configured to be inserted from a proximal end of the body and extend through the cavity and into the passageway;   wherein the collar is configured to rotate the delivery tube about the longitudinal axis; and   wherein the lever is configured to move the driving rod distally toward the delivery tube when the lever is actuated toward the handle.   
     
     
         2 . A device for injecting materials into a patient, the device comprising:
 a body comprising a handle and a lever;   a delivery tube comprising a passageway along a longitudinal axis and a nozzle with an opening, the delivery tube configured to couple with a distal end of the body; and   a driving rod configured to be inserted into the body and extend into the passageway;   wherein the delivery tube is configured to rotate about the longitudinal axis; and   wherein the lever is configured to move the driving rod distally when the lever is actuated toward the handle.   
     
     
         3 . The device of  claim 2 , wherein the passageway of the delivery tube is configured to be filled with fusion-promoting material. 
     
     
         4 . The device of  claim 2 , wherein the opening in the nozzle is a lateral opening. 
     
     
         5 . The device of  claim 2 , wherein one or more of the delivery tube and driving rod are at least partially flexible. 
     
     
         6 . The device of  claim 2 , wherein the driving rod comprises a plurality of ratchet teeth that are engaged by an advancement mechanism coupled to the lever. 
     
     
         7 . The device of  claim 2 , further comprising a gripping element coupled to the lever that is configured to grab the driving rod when the lever is actuated. 
     
     
         8 . The device of  claim 2 , wherein the delivery tube and driving rod are disposable. 
     
     
         9 . The device of  claim 2 , wherein the driving rod is configured to move unidirectionally in the distal direction. 
     
     
         10 . The device of  claim 2 , wherein the nozzle comprises an angled inner surface. 
     
     
         11 . The device of  claim 2 , wherein the driving rod comprises at least one channel configured to align with at least one tab on the body. 
     
     
         12 . The device of  claim 2 , wherein the delivery tube further comprises indications representing the depth of insertion of the delivery tube into a patient. 
     
     
         13 . A kit for injecting materials into a patient, the kit comprising:
 a delivery tube comprising a passageway along a longitudinal axis with an opening at both ends of the passageway;   a funnel configured to couple with an end of the delivery tube;   a plug configured to block one of the openings of the delivery tube; and   a ramrod comprising a shaft that is configured to fit in the passageway of the delivery tube.   
     
     
         14 . The kit of  claim 13 , the kit further comprising:
 a body comprising a handle and a lever; and   a driving rod configured to be inserted into the body and extend through the body;   wherein the delivery tube is configured to releasably couple to a distal end of the body and be rotatable about the longitudinal axis while coupled to the body; and   wherein the lever is configured to move the driving rod distally into the passageway of the delivery tube when the lever is actuated toward the handle.   
     
     
         15 . The kit of  claim 14 , wherein the body further comprises a collar configured to rotate the delivery tube about the longitudinal axis. 
     
     
         16 . The kit of  claim 14 , wherein one or more of the delivery tube and driving rod are at least partially flexible. 
     
     
         17 . The kit of  claim 14 , wherein the delivery tube and driving rod are disposable. 
     
     
         18 . The kit of  claim 13 , wherein at least one of the openings in the delivery tube is a lateral opening. 
     
     
         19 . The kit of  claim 13 , wherein the passageway of the delivery tube is configured to be filled with fusion-promoting material. 
     
     
         20 . The kit of  claim 19 , wherein the ramrod is configured to push the fusion-promoting material through the funnel into the passageway. 
     
     
         21 . The kit of  claim 13 , wherein at least a portion of the ramrod is flexible. 
     
     
         22 . The kit of  claim 13 , wherein the funnel comprises a bent funnel stem.
