Double-layer weaving polyester artificial vessel

Double layered weaving artificial blood vessel made of terylen fiber can provide good suturing performance and promote affinity, adhesion and intrusive growth of receptor tissue. The artificial bloodvessel is compact enough, has low porosity thereby exempting blood pre-coagulation in operation. The artificial blood vessel is prepared from 5/2 filling face soleil weave as inner wall of blood vessel and 4/4 huckaback weave as outer wall of blood vessel by combine weaving into double-layer structure with combination of soleil weave and tabby as inner layer and huckaback weave as outer layer.

Slope supporting device

The invention relates to the technical field of slope supporting, in particular to a slope supporting device which comprises a foundation frame plate, a slope angle frame plate in butt joint with the foundation frame plate and a slope surface frame plate connected to the slope angle frame plate. The slope angle frame plate and the foundation frame plate are combined into a herringbone structure, and the slope surface frame plate is connected with the slope angle frame plate through a rotary connecting piece; a supporting vertical frame is arranged on the foundation frame plate, a tension frame is arranged on the slope angle frame plate, and the supporting vertical frame forms an obliquely upward tension trend on the tension frame; the slope surface frame plate comprises positioning supporting plates, connecting pieces used for connecting the adjacent positioning supporting plates and positioning pieces used for fixing the positioning supporting plates to the slope surface, buffering connecting ...

MACHINE MADE SYNTHETIC SMALL BLOOD VESSEL

The invention relates to a machine-made artificial small blood vessel of the diameter 5mm.-0.6mm.The wall of blood vessel is made with the composite organic structure of skein with plain or twill weave yarns and adopts the forming technology to treat in boiling water. It can be bent arbitaryly, and no shrinkage and subsidence happened on vessel wall, no falling-off in margin of cross-section, and blood oozing rate is appropriate. It is proved through experiment on animal and clinical application that it can be used for ortery and vein with good effect. It is an ideal substitute for small blood vessel in surgical operation.

Abrasive belt polishing and grinding robot

The invention discloses an abrasive belt polishing and grinding robot, and relates to the field of polishing equipment. Through the arrangement of the chipping box, the guide frame, the guide cover, a buffer pipe, a telescopic rod, a first spring, a pressing plate and a pressing roller, chippings generated during grinding can be collected under the action of the chipping box, the influence of the chippings generated during grinding on the working environment is effectively reduced, and meanwhile under the action of the guide frame, the guide cover and the buffer pipe, the chippings generated during grinding can be effectively prevented from being damaged. The situation that chippings fall out of the chipping box due to the backflow phenomenon after entering the chipping box is effectively prevented, a buffer pipe can cool the chippings, damage of the high-temperature chippings to the chipping box is reduced, when a to-be-polished piece is polished, the chipping box can be tightly attached ...
