A segmented intervertebral body fusion support includes a plurality of segments, the segments including an initial segment, a final segment and at least one intermediate segment. The intermediate segment has a generally trapezoidal configuration and the initial and final segments include tapered side walls providing triangular gaps between adjacent segments. A draw wire is fixed to the first segment and passes through the remaining segments. By pulling the draw wire relative to the segments, the segments are drawn together in a generally arcuate configuration. The draw wire includes an enlargement that passes through the final segment and engages a plurality of fingers on the final segment, which prevents the draw wire from retracting, maintaining the arcuate configuration. The segmented device can be inserted through a laparoscopic device into the intervertebral space and can be subsequently drawn into the arcuate configuration to establish the desired intervertebral spacing.

The present invention discloses a surgical maneuvering system, in which movement of a moving element is used to control a surgical device such as a surgical tool or an endoscope. The moving element can be a tool or a portion of an operator's body. The relationship between the moving element and the surgical device can be any of: motion of a moving element controlling motion of a surgical device, motion of a moving element controlling an action of a surgical device, a command of a moving element controlling motion of a surgical device, or a command of a moving element controlling an action of the device. Commands are typically arbitrary movements such as shaking a tool. Actions are changes in a surgical device that do not change its overall position, such as closing a grasper.

ClotFoam is a surgical sealant and hemostatic agent designed to be used in cases of non-compressible hemorrhage. It can be applied in the operating room through laparoscopic ports, or directly over lacerated tissue in laparotomy procedures or outside the operating room through a mixing needle and/or a spray injection method following abdominal, chest, extremities or other intracavitary severe trauma to promote hemostasis. Its crosslinking technology generates an adhesive three-dimensional polymeric network or scaffold that carries a fibrin sealant required for hemostasis. When mixed, Clotfoam produces a foam that spreads throughout a body cavity reaching the lacerated tissue to seal tissue and promote the coagulation cascade.

The viscoelastic attachment properties of the foam as well as the rapid formation of a fibrin clot that ensure that the sealant remains at the site of application without being washed away by blood or displaced by movement of the target tissue .

The invention relates to the field of laparoscopic micro-invasive surgery, in particular to a spindly non-pneumoperitoneum device for a single-port laparoscopy. According to the spindly non-pneumoperitoneum device, the defects of small surgery space, poor surgical field exposure and great quantity of abdominal incisions in a traditional non-pneumoperitoneum technology can be overcome. The spindly non-pneumoperitoneum device consists of a fixed frame, a suspension mechanism and a spindle mechanism. Due to the adoption of the technical scheme that a support ring enables spindly spokes to be stretched off and be arrayed in an umbrella shape by upwards lifting a suspender, an anterior abdominal wall is semi-spherically lifted and suspended by the spokes arrayed in an umbrella shape and the phenomenon that the surgery space becomes smaller and narrower due to the fact that abdominal walls on two sides gather towards the middle to extrude intestinal canal to be concentrated to the middle by a suspending pull force of the abdominal walls is avoided; due to adoption of single incision in umbilical region, an illuminating probe, surgical instruments and the like extend into an abdominal cavity for surgery by using a hollow structure of the device; and due to the adoption of a rotational suspension device, the surgical instruments obtain a more favorable operation angle and the problems of small surgery space, insufficient surgical field exposure and great quantity of abdominal incisions in the traditional non-pneumoperitoneum technology are better solved.
