A suture needle instrument having improved connection means enabling
a hollow suture needled to be attached to a handle in a variety
of orientations. The suture needle is provided with user accessible
suture channels and suture advancing wheels to facilitate cleaning
and repair.
An endoscopic suture needle and related surgical endoscopic suturing
devices are to be used in conjunction with an endoscope. The invention
relates to suturing of internal body tissue as part of a surgical
procedure which may be diagnostic, therapeutic or both. In accordance
with the present invention, there is provided an endoscopic surgery
system comprising a temperature biased suture needle, a needle grasping
device, and an elongated catheter or other delivery tube, a endoscopic
surgery system configured for use in conjunction with a flexible
or rigid endoscope insertion member.
Described herein is a device that may be used in various applications,
such as medical applications, and, particularly in laparoscopic
procedures, to manipulate and/or introduce objects within or into
the body. In one embodiment of the invention, a device includes
a cannula with a handle that remains exterior to the body and an
extendable member on a portion of the device that may be inserted
into the body. The handle, which controls the extendable member,
may be moved in an axial direction to extend or retract the extendable
member from the interior of the cannula. It may also be rotated
to swivel the extendable member. Furthermore, the extendable member
may include at least one hole that may be used to, for example,
grasp a surgical suture or suture needle. Thus, the device may be
used to introduce such objects into the body and manipulate them
therein.
The invention provides a multifunctional suture needle that may
be used to draw a suture through tissue surrounding a wound while
simultaneously delivering a bioactive fluid through the needle tip.
The suture needle possesses an internal cavity capable of containing
a fluid, and a fine aperture adjacent to the point of the needle
through which the fluid may egress. The fluid may be driven from
the needle through the needle tip with a compressed gas that is
sealed within the cavity adjacent to the fluid. Alternatively a
fluid conducting suture may be employed to deliver fluid through
the internal passage of the suture needle and out the aperture adjacent
to the tip of the needle. The rate at which the fluid is emitted
from the suture needle may be controlled by carefully selecting
the fluid viscosity, design of the needle or suture passages, and
pressure applied to the fluid.
