Specific embodiment
The present invention is further elaborated on it is intended to be helped reader more with reference to specific embodiments and accompanying drawing
Understand well the flesh and blood of the present invention it is impossible to be interpreted as any restriction to the scope of the present invention.
The present invention provides a kind of incision protection and pull device, has outer snap ring, interior snap ring and passage, outer snap ring and Nei Ka
Ring is the ring of closure, and be arranged in parallel, the tubular structure that passage is formed for soft material, be arranged at outer snap ring and interior snap ring it
Between, and the two ends of passage are tightly connected with outer snap ring and interior snap ring respectively, the material forming passage includes hemostatic material.The present invention
The incision protection providing and pull device can be used for surgical operation, can be effectively real while providing effective incision protection
Existing hemostatic function, reduces the oozing of blood of cutting part in operation process
In incision protection and pull device that the present invention provides, interior snap ring, outer snap ring and passage three part can be split type,
Assembled formation after processing respectively.Specifically, interior snap ring and outer snap ring can adopt thermoplastic polyurethane elastomer
(thermoplastic polyurethane, tpu), closure made by the material such as silica gel or polyethylene (polyethylene, pe)
Then passage and interior snap ring and outer snap ring be attached by ring-type again using modes such as bonding or welding.This incision protection and leading
Opening apparatus may also be employed integrally formed, and such as, all using silica gel, three parts are integrally machined shaping for interior snap ring, outer snap ring and passage.
In operation process, interior snap ring is put into inside otch, and outer snap ring is fixed on outside otch, pastes around passage and otch
Close, for protecting otch surrounding tissue, passage can effectively prevent oozing out of cutting part blood.Otch for pneumoperitoneum formula is protected
Shield and pull device, usual outer snap ring also can seal against, with one, the closure covering, closure is usually provided with
Some closure ducts coming in and going out for apparatus used in operation.
In the present invention, passage can include substrate layer and hemostatic layer, and hemostatic layer is arranged at the periphery of substrate layer, hemostatic layer by
Hemostatic material is formed.Substrate layer can adopt tpu or silica gel thin film, and hemostatic layer can be by the side such as hot pressing, bonding, sewing or spraying
Formula is arranged on substrate layer periphery.After detailed process can be for first shaping interior snap ring, outer snap ring and substrate layer three part, then will stop
Blood layer is arranged on this substrate layer periphery.Last layer hemostatic layer is such as pressed by the way of heat seal on substrate layer.Or can also
Hemostatic layer is first spread on the one side of substrate layer material by modes such as spraying, dipping, bonding or sewings, then will be covered with hemostasis again
The substrate layer material of layer is processed into tubulose；Or substrate layer is directly processed on hemostatic layer, such as can spray in hemostatic layer
Apply last layer silica gel, be thin film after being dried, be then reprocessed into the shape of passage.
Above-mentioned hemostatic layer can be covered with the periphery of whole substrate layer, or the part that can only cover substrate layer periphery.
In an embodiment of the invention, the incision protection providing and pull device height (i.e. passage length) can be outer by upset
Snap ring thus passage is adjusted in outer snap ring, the upset of outer snap ring for convenience, the section of outer snap ring can be
Non-circular, for example, dumb-bell shape etc..In this case as well, it is possible to only be coated near a part for outer snap ring in substrate layer periphery
Blood layer, for example, be coated with hemostatic layer in substrate layer periphery near 1/3 or 1/2 length of outer snap ring.
In the present invention, passage also can directly be formed by hemostatic material, is more beneficial for reducing channel thickness.Stopping as passage
Blood material for example using the macromolecule membrane including releasable haemostatic medicament or reagent, or can directly adopt hemostatic gauze as logical
Road.
Above-mentioned hemostatic material can use hemostatic gauze, the hemostatic gauze of the absorbent cotton that such as stops blooding, or other have hemostasis
The material of function, such as part fabric containing stanch fibre etc..Or, hemostatic material can also have hemostatic function by inclusion
The material of the compositions such as collagen-based materials, medicine or biological reagent is formed.
