Vacuum assisted surgical dissection tools

Abstract

A surgical device includes a handle, an elongated tube extending distally from the handle, and a suction tip at a distal end portion of the elongated tube. The suction tip has a cavity formed therein. A cutting blade is positioned at least partially within the cavity and rotatable across the cavity to sever tissue, the cavity dimensioned to receive the severed tissue for removal from a patient's body.

1 . (canceled) 
     
     
         2 . A surgical device, comprising:
 an elongate member defining a vacuum lumen; and   a suction tip supported by the elongate member and defining a cavity in fluid communication with the vacuum lumen of the elongate member, the suction tip supporting first and second cutting blades configured to pivot between an open position and a closed position to sever tissue received within the cavity of the suction tip.   
     
     
         3 . The surgical device of  claim 2 , further comprising a first post pivotably coupled to the elongate member by a first pin. 
     
     
         4 . The surgical device of  claim 3 , further comprising a second post pivotably coupled to the first post by a second pin. 
     
     
         5 . The surgical device of  claim 4 , wherein the second post supports the suction tip. 
     
     
         6 . The surgical device of  claim 4 , wherein the first pin and the second pin are transverse to one another. 
     
     
         7 . The surgical device of  claim 6 , wherein the first post and the second post articulate relative to the elongate member in different directions. 
     
     
         8 . The surgical device of  claim 4 , wherein the elongate member defines a first bore and the first post includes a first clevis, the first pin disposed through the first bore and the clevis to secure the first post to the elongate member. 
     
     
         9 . The surgical device of  claim 8 , wherein the first post defines a second bore and the second post includes a second clevis, the second pin disposed through the second bore and the second clevis to secure the second post to the first post. 
     
     
         10 . The surgical device of  claim 2 , further comprising a handle supported on a proximal end portion of the elongate member. 
     
     
         11 . The surgical device of  claim 10 , wherein the handle includes a switch to selectively activate a vacuum through the vacuum lumen. 
     
     
         12 . A surgical system, comprising:
 a surgical device including an elongate member and a suction tip supported by the elongate member, the elongate member defining a vacuum lumen, the suction tip defining a cavity in fluid communication with the vacuum lumen, the suction tip supporting first and second cutting blades configured to pivot between an open position and a closed position to sever tissue received within the cavity of the suction tip; and   a container configured to receive the severed tissue from the suction tip.   
     
     
         13 . The surgical system of  claim 12 , further comprising a first post pivotably coupled to the elongate member by a first pin. 
     
     
         14 . The surgical system of  claim 13 , further comprising a second post pivotably coupled to the first post by a second pin. 
     
     
         15 . The surgical system of  claim 14 , wherein the second post supports the suction tip. 
     
     
         16 . The surgical system of  claim 14 , wherein the first pin and the second pin are transverse to one another. 
     
     
         17 . The surgical system of  claim 16 , wherein the first post and the second post articulate relative to the elongate member in different directions. 
     
     
         18 . The surgical system of  claim 14 , wherein the elongate member defines a first bore and the first post includes a first clevis, the first pin disposed through the first bore and the clevis to secure the first post to the elongate member. 
     
     
         19 . The surgical system of  claim 18 , wherein the first post defines a second bore and the second post includes a second clevis, the second pin disposed through the second bore and the second clevis to secure the second post to the first post. 
     
     
         20 . The surgical system of  claim 12 , further comprising a handle supported on a proximal end portion of the elongate member.
