Surgical clamp with improved traction
View Patent ↗A surgical clamp includes opposing jaws and a covering enhancing traction between the jaws and a body conduit. A multiplicity of fibers oriented to extend longitudinally between the clamp and conduit may be composed of filaments and either woven or non-woven to form a fabric. A variety of weaves are contemplated to provide different textures, each having its own traction characteristics. The nature of the weave can control characteristics such as smoothness, absorption, and texture. The fibers or filaments may be formed from any solid or semi-solid material, adding its own characteristics to the resulting fabric insert or clamp.
1. A jaw insert adapted for use with a surgical clamp to occlude a body conduit, comprising:
a rigid base, the base being adapted to be coupled to the clamp;
a first layer having a top surface, a bottom surface and two side surfaces, the bottom surface of the first layer being positioned on the base of the insert; and
a second layer at least partially covering the top surface and each of the two side surfaces of the first layer, the second layer providing traction characteristics,
wherein the insert being adapted such that during use, when a force is applied to the body conduit by the insert through the closing of the clamp, the insert compresses, thereby causing the side surfaces of the first layer of the insert to spread outwardly causing at least a portion of the second layer of the insert that is covering the side surfaces of the first layer of the insert to contact the body conduit and provide additional contact area between the second layer and the body conduit;
wherein the second layer prior to compression of the insert is spaced from the top surface of the first layer and after compression of the insert contacts the top surface of the first layer.
2. The jaw insert recited in claim 1 , wherein the first layer comprises a compliant material and the second layer comprises a material less compliant than the first layer.
3. The jaw insert recited in claim 2 , wherein the second layer is formed of fibers.
4. The jaw insert recited in claim 3 , wherein the fibers are woven.
5. The jaw insert recited in claim 3 , wherein the fibers are non-woven.
6. The jaw insert recited in claim 2 , wherein the first layer includes an open cell-foam.
