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.

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.

6. The device claimed in claim 5 wherein said tubular member is formed by a generally cylindrical tubular shaft.

7. The device claimed in claim 5 wherein said tubular member is substantially rigid.

8. The device claimed in claim 5 wherein said tether is secured to said tubular member adjacent the proximal end thereof.

9. The device claimed in claim 8 further including a tubular member support body at the proximal end of said tubular member and wherein said tether engages said support body.

10. The device claimed in claim 5 wherein said tether and said pouch support section coextend within said tubular member when said pouch support section is in said retracted condition.

11. The device claimed in claim 5 further including a tubular member support body at the proximal end of said tubular member and a manually operated slidable member associated with the support body for reciprocating sliding movement with respect to said support body, said slidable member connected to said pouch operator for shifting said pouch support section between said conditions.

12. The device claimed in claim 5 wherein said mounting structure for connecting said pouch and said pouch support section comprises a pocket surrounding said mouth, said pouch support section extending through said pocket.

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;
