 References Cited UNITED STATES PATENTS Jones et all 128/339 [57] ABSTRACT A surgical needle capturing device includes a handle member having a tip at one end thereof in the form of a solid block which may be penetrated by a surgical needle whereby manipulation of the handle member permits manipulation of the needle.  
 11 Claims, 5 Drawing Figures SURGICAL NEEDLE CAPTURING DEVICE BACKGROUND OF THE INVENTION Cutting and sewing are two particularly important aspects of surgery. Ideally each should be done effortlessly with accuracy and economy of movement. With respect to sewing, a vast array of needle and suture devices are available. These devices, however, have been basically unchanged since the introduction of the modern needle holder and curved needle. Six stitch movements are involved in sewing, namely, pushing the needle partly through the tissue, releasing the needle holder, gripping the point, pulling the needle and suture through the tissue, supporting the needle with the left hand fingers or forceps and regripping the shank of the needle with the needle holder. Attempts have been made to provide a surgical needle capturing device such as exemplified in U.S. Pat. No. 3,5l L242. Other patents of interest are U.S. Pat. Nos. 2,589,499 and 562,730.  
 SUMMARY OF THE INVENTION An object of this invention is to provide a needle capturing device which readily lends itself to surgical practice.  
  A further object of this invention is to provide such a surgical needle capturing device which insures holding the needle and then permitting it to be manipulated by movement of a handle member.  
  In accordance with this invention the surgical needle capturing device includes a handle member having a tip at one end which may be penetrated by the needle and once penetrated may be manipulated by manipulation of the handle member. In the preferred form of this invention, the tip is a body member in the form of a solid block adapted to rest against a vessel wall and having sufficient resistance to permit penetration thereof by a surgical needle and then to grip the needle so that it may be manipulated.

  FIG. 2 is a side view in elevation partly in section of the device shown in FIG. 1;  
  FIG. 3 is a bottom plan view of the device shown in FIGS. l2;  
  FIG. 4 is an end view in elevation of the device shown in FIGS. I3; and  
  FIG. 5 is a perspective view of the device shown in FIGS. 1-4.  
 DETAILED DESCRIPTION As illustrated in the drawings, the surgical needle capturing device includes a handle member or wand 12 which is in the form of a flat plate-like member adapted to be received in the chuck 14 of a conventional manipulating tool 16. Since the details of the manipulating tool and its chuck may take various forms including conventionally available forms a detailed description thereof is not necessary. At the remote end of the handle 12 is a tip or body member 18 formed, for example, of any suitable material such as silicone rubber. In the illustrated embodiment the tip is a solid block of generally elliptical shape in cross-section. It is to be understood that other geometric shapes may be utilized. Additionally. the term solid block is not meant to preclude the use of a body member having hollow portions provided there is sufficient solid material to grip a needle which penetrates the body member. In the illustrated embodiment the solid block includes a series of three passages 20 extending a substantial distance into body member 18. A pin or pricker 22 is inserted into each passage with its point 24 extending therefrom.  
  In the illustrated form of this invention the tip or body member has a maximum length of about 0.26 inches and a maximum width of about 0.225 inches and a maximum heighth of about .l6 inches. The exposed position of the wand or handle I2 is about V2 inches long and V8 inches wide and has a thickness of about 0.025 inches. The pins 22 project from body member I8 about 0.025 inches. Wand or handle 12 terminates in a bifurcation or U-shaped extension which is disposed within the tip or body member 18 to add sufficient stability thereto with the pins being located between the legs of the U. As best shown in FIG. 2, the pin most remote from handle or wand 12 is slightly shorter than the other pins since it is disposed in the curved portion of the tip or body member 18. In this manner a uniform amount of projection is maintained with respect to all pins 22. It is to be understood that other dimensional relationships and geometric shapes may be utilized within the concepts of this invention.  
  In operation the body member is pressed against the vessel wall and the tissue is stabilized by the prickers or pins 22. The surgical needle 28 is pushed into and penetrates the body member 18 and is gripped by the body member due to the nature of the silicone or rubber-like material. The needle may then be manipulated by simple manipulations of the surgical tool I6. In practice the needle tip is embedded in the silicone to a point where its resistance is greater than that of the shank of the needle against the vessel wall. The needle holder is released and the left thumb and forefinger perform a pin-rolling motion to complete passage of the needle. The needle is thus immediately in position to be regripped and extracted from the body 18 and ready to be used for the next time.  
  In the manner described above, a surgical needle capturing device is provided employing low cost materials wherein the device is adaptable to existing surgical tools and may be conveniently used by surgeons. Because of the low cost nature of device It] after it has been used it may be discarded and a new device loaded into chuck l4 of tool 16 so that the entire reloadable unit is disposable and may be discarded after a single use.
