Abstract
The conduit of fetching intravascular thrombus in human internal organ belongs to medical instruments field.Technical scheme mainly is to have one to have side opening and bell-mouthed trocar sheath outside having the conduit of sacculus.Especially be fit to get cerebral thrombosis, also desirable simultaneously kidney,spleen,liver, mesentery and in the embolus at pipe places such as tremulous pulse and arteriae bronchiales down, this device can not operated under the situation of blocking blood flow in getting the bolt process, and has and use that wound is little, speed fast and dangerous characteristics such as little.
Description
The present invention relates to be used to remove the utensil of vascular peg stay, belong to medical instruments field.
Cure in the thrombosed apparatus of limbs arteries and veins in operation at present, have a kind of front end to have the conduit of sacculus.Its using method is, by at the suitable position surgical incision of limbs, the conduit that front end is had bad capsule inserts limb artery, after sacculus passes thrombosis along tremulous pulse, at the rear end of conduit injection liquid or gas sacculus has been splashed, when pulling out conduit, sacculus can be taken thrombosis out of from the otch of tremulous pulse subsequently.The conduit of this structure is only applicable to take out the thrombosis that forms in the limb artery.And the blood vessel that communicates indirectly for those aortas or upper and lower caval vein and limb artery, especially the embolus of some internal organs blood vessel in cerebrovascular and the body, as only using this device, tend to make emboluses such as thrombosis, foreign body to enter other bypass tremulous pulse and internal organs again, form new thromboembolism.Therefore, curing emboluses such as brain and the angiopoietic thrombosis of some internal organs, is one of difficult problem of the world today.At present, have the method that adopts operation " bridging " to treat the embolus of some organ blood vessel in brain and the body abroad, promptly the blood vessel at the embolus two ends connects a path in addition, but this method still exists big, dangerous height of wound and complicated operation and speed to wait defective slowly.
The objective of the invention is the defective that only is suitable for getting the limb artery embolus at original foley's tube, a kind of apparatus that the bypass blood vessel is arranged in getting the embolus stroke and be fit to cure brain and internal organs of the body embolus that is applicable to is provided.This apparatus is also not blocking blood flow and more convenient operation under the X-ray line in getting the embolus process.
Technical solution of the present invention is except that adopting front end to have the conduit of sacculus, to dispose a trocar sheath again.Be pressed into embolus in the sleeve pipe and together taking-up with sacculus.Therefore, solved the difficult problem that embolus can enter other tremulous pulse or internal organs effectively.
According to such scheme, an end of trocar sheath is installed a usefulness latex and is coated with the horn mouth that one deck X-ray opaque material is made outward, also the direct mold pressing of trocar sheath can be gone out horn mouth; Can get out 3～8 side openings on the tube wall of trocar sheath, its diameter is reserved one section imperforate section at trocar sheath near a bell-mouthed end between 0.5～2 millimeter, and its length can be taken between 40～120 millimeters.Bell-mouthed effect mainly is to be suitable for use in the situation that has horizontal blood vessel to connect between embolus and the puncture portion blood vessel.Owing to have side opening on the trocar sheath, blocking blood flow not after it inserts tremulous pulse.And the side opening number is got more than 3 or get 8, and its diameter is taken between 0.5～2 millimeter, is that ambassador's trocar sheath lacking toughness easy to break is not crossed in the reason aperture on the one hand, be on the other hand as the aperture get too small, can influence in the trocar sheath and the blood flow between vascular bypass.Trocar sheath reserves one section imperforate section and length is taken between 40～120 millimeters, mainly act as emboluses such as holding thrombosis, aeroembolism, foreign body, as have side opening at this, will make the embolus leakiness for trocar sheath.
For realizing purpose of the present invention, also can take following measure.Trocar sheath adopts polyethylene or other macromole aggressiveness plastic, into 4～5 finer wires are moulded in overcoat tube wall middle level, so that make it keep certain elastic memory, for operate accurately, convenient and prevent the tube wall blood coagulation outside casing wall twine or coat the material of X-ray opaque and cover one deck heparin mould outward, the caliber of trocar sheath and length can be decided according to thickness and embolus position, the patient age of blood vessel, if when getting renal artery, Mesenteric artery and arteriae bronchiales embolus, also need make the conduit of differently curved degree.Horn mouth is made the outer material that covers one deck X-ray opaque with latex.As use polyethylene plastic, bell-mouthed thickness should be thinner than trocar sheath and both make it soft and full of elasticity.
Advantage of the present invention is can draw in embolus in the brain got and the internal organs of the body in the trocar sheath and together take out external, not only solved the get embolus problem of mould to perforation and branch vessel arranged between thromboembolism and puncture portion blood vessel, also desirable simultaneously kidney,spleen,liver, mesentery and in the embolus located such as tremulous pulse and arteriae bronchiales down, especially be more suitable for getting cerebral thrombosis.This device can not operated under the situation of blocking blood flow in getting the bolt process, and can by piercing method avoid cutting tremulous pulse and have that wound is little, speed is fast and dangerous characteristics such as little, has also solved a great problem of the world today simultaneously.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the guide-tube structure sketch map of fetching intravascular thrombus in human internal organ.
[2] be that anterior cerebral artery [7] is a middle cerebral artery, [8] are posterior cerebral artery, and [11] are internal carotid artery.
The present invention is described in further detail below in conjunction with (accompanying drawing) embodiment:
A kind of conduit that comprises the fetching intravascular thrombus in human internal organ [5] of sacculus [6] and conduit [1] also has a trocar sheath [3] outside front end has the conduit [1] of sacculus [6].One end of trocar sheath [3] has a horn mouth [4], has 8 side openings [10] on trocar sheath [3] tube wall, and the diameter of side opening [10] is 1 millimeter, is going up one section imperforate section [9] in addition near the trocar sheath [3] of horn mouth [4], and the length of imperforate section [9] is 60 millimeters.Trocar sheath [3] adopts vinyon, also can adopt other similar material, the caliber of trocar sheath [3] is 4 millimeters, mould into 3 steel wires in the wall middle level, outer wall twines the metal pattern strip of X-ray opaque, outermost layer covers one deck heparin film, and horn mouth [4] adopts latex to make the outer soft metal mould that covers one deck X-ray opaque.Elder generation is at limbs or suitable position surgical incision during use, the conduit [1] that again front end is had sacculus [6] inserts limb artery, after sacculus [6] passes thrombosis along tremulous pulse, the contrast agent that injects normal saline or dilution in the rear end of conduit [1] has been splashed sacculus [6], spur conduit [1] then and make sacculus that thrombosis is drawn in trocar sheath [3], simultaneously take out external from puncture portion it at last.
