Abstract
A surgical device for retrieving an object from inside a body. The device includes a shaft, a compressible pouch for receiving the object positioned adjacent the first end of the shaft. The pouch includes a mouth which may be opened and closed. An introducer sleeve is slidably positioned along the shaft for enclosing the pouch. A slotted support member having a first end affixed to the second end of the shaft, is also provided. Further, a slidable handle member is slidably positioned along the slotted support member, and an interconnecting member extends through the shaft and is interconnected with the handle, pouch and the slotted member for closing and opening the pouch, such that sliding the handle along the slotted member operates to open and close the pouch of the device.

1. A surgical device for retrieving an object from a body, comprising,
an operating assembly including a shaft portion having a longitudinal bore extending between first and second ends, a closure portion having a support member engaged with said second end of said shaft portion, a slidable member slidably mounted on said support member for operation of said assembly, and a flexible elongate interconnecting member secured at a first end with said slidable member and engagable with said support member at a second end, a compressible pouch for receiving the object, having a mouth portion secured adjacent said shaft portion first end, and which is movable between an open position and a closed position upon operation of said slidable member, said pouch comprising a pocket surrounding said mouth portion, an introducer sleeve slidably mounted on said shaft portion, and having a longitudinal bore for housing said pouch, and said interconnecting member disposed within said shaft portion and said pouch pocket such that manual movement of said slidable member with respect to said support member moves said pouch mouth portion between open and closed positions, said interconnecting member having a bend intermediate its first and second ends to form a first arm between said first end of said interconnecting member and said bend, and a second arm between said bend and said second end, of said interconnecting member, said first and second arms engaged within said shaft portion bore and said bend and portions of said first and second arms engaged within said pouch pocket, said interconnecting member second end comprising a stop for engaging said support member to permit limited movement of said second end with respect to said support member.

4. A surgical device for retrieving an object from a body, comprising:
-
a. a shaft having a longitudinal bore therethrough; b. a compressible object receiving pouch having a mouth which may be opened and closed; c. a closure for closing and opening said pouch comprising, a support member attached to said shaft, a slidable member slidably attached to the support member, and an interconnecting member interconnected with said slidable member; said interconnecting member comprising a flexible elongate member extending through said shaft and engaged with said pouch surrounding said mouth, and having first and second ends and a bend intermediate said ends, said first end engagable with said support member, said second end secured to said slidable member, and said bend engaged with said pouch adjacent said mouth, and said pouch mouth secured to said support member by a tether, said tether having first and second ends secured to said support member and engaging said pouch at a location between said ends of said tether such that sliding said slidable member operates said closure while maintaining the position of said pouch mouth engaged with said interconnecting member adjacent said bend of said interconnecting member.

5. A surgical device for retrieving material from within a patient'"'"'s body comprising:
-
an elongated tubular member having a first distal end region insertable into the patient'"'"'s body and a second proximal end region said distal end region having a diametrical extent that is small compared to the length of the member; a material retrieval pouch at the distal end region of the tubular member, said pouch having a material receiving mouth leading to a collapsible pouch body; and
,a pouch operator for closing and opening said mouth comprising a pouch support reciprocatable within said tubular member in the direction of extent of the tubular member, said pouch support comprising at least a stiffly resilient, flexible pouch support section shiftable between a first, deployed condition wherein said pouch support section projects from the distal end of said tubular member to define an open loop having a diametrical extent substantially greater than the diametrical extent of said tubular member distal end region and a second, retracted condition wherein at least a substantial portion of said pouch support section is disposed within and resiliently confined by said tubular member; mounting structure connecting said pouch and said pouch support section for relative sliding motion as said flexible pouch support section is operated between said deployed and retracted conditions, said pouch mouth opened for receiving material by said pouch support section as said pouch support section is deployed to form said loop and said pouch mouth substantially closed to secure material within said pouch body when said pouch support section is operated to its retracted condition; and
,a tether secured to said pouch at a pouch location adjacent the distal end of said tubular member, said tether comprising a flexible line-like element extending from said pouch location into said tubular member distal end, said tether preventing said pouch location from moving away from said tubular member distal end as said pouch support section is operated to its deployed condition so that said pouch mouth is opened by said pouch support section. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. A surgical device for retrieving material from within a patient'"'"'s body comprising:
-
an elongated tubular member having a first distal end region insertable into the patient'"'"'s body and a second proximal end region, said distal end region having a diametrical extent which is small compared to the length of said tubular member; a material retrieval pouch located adjacent the distal end region of the tubular member, said pouch having a material receiving mouth leading to a collapsible pouch body; a pouch support reciprocatable within said tubular member in the direction of extent of the tubular member, said pouch support comprising at least a stiffly resilient, flexible pouch support section, said pouch support and said tubular member relatively reciprocated to a first position wherein said pouch support section forms an open loop extending from the distal end of said tubular member having a projecting loop portion remote from said distal end, said loop having a diametrical extent greater than the diametrical extent of said tubular member distal end region, said pouch support and said tubular member relatively reciprocated to a second position wherein at least a substantial portion of said pouch support section is disposed within said tubular member; mounting structure connecting said pouch and said pouch support section, said mounting structure slidably engaging said pouch support section in the vicinity of said pouch mouth so that said pouch mouth is opened and substantially conformed to the shape of said loop when said pouch support section forms said open loop; and
,a tether secured to said pouch body at a pouch attachment location adjacent the pouch mouth, the pouch attachment location adjacent the tubular member distal end when the pouch support section is in said first position, said tether comprising a thin flexible element extending within said tubular member and securing said pouch attachment location against moving away from said tubular member distal end toward said projecting loop portion when said pouch support section is in said first position. - View Dependent Claims (14, 15)
