The specific embodiment
With reference to accompanying drawing 1~4, this utility model provides the splanchnocoel Centesis instrument, the guide wire 3 that includes puncture needle tubing 1, indwelling flexible pipe 5 and be used for to keep somewhere flexible pipe 5 importing human bodies, the mouth mouth of an end for penetrating for guide wire 3 of needle tubing 1 wherein punctures, the other end is provided with the piercing needle 2 of hollow, and guide wire 3 can pass by the hollow position or the indwelling flexible pipe 5 of piercing needle 2.The operating process of this utility model embodiment one is: at first piercing needle 2 is sent into human body; Then guide wire is sent into the mouth mouth of puncture needle tubing 1, inserted the hollow position of piercing needle 2; Take out piercing needle 2, guide wire 3 is stayed in human body; To keep somewhere flexible pipe 5 and be enclosed within on the guide wire 3, after will keeping somewhere flexible pipe 5 and sending into human body, detach guide wire 3 along guide wire 3; Keep somewhere an end of flexible pipe 5 at last and stay in the human body, the other end outside human body for repeatedly drawing water or injection is used.This utility model adopt to be kept somewhere flexible pipe 5, the damage to human body of can avoiding repeatedly puncturing.To keep somewhere the problem that flexible pipe 5 is inserted human body by the ingenious solution of linking of guide wire 3, be a kind of invention on the splanchnocoel puncture technique.
Referring to Fig. 5, this utility model provides further scheme: utility model embodiment two to be provided with can increase the needle sleeve 6 of puncture wound surface, and needle sleeve 6 is socketed in outside the piercing needle 2.If the puncture wound surface is too little, to keep somewhere the importing of flexible pipe 5 and will compare difficulty, needle sleeve 6 can increase the puncture wound surface.
In order to avoid injuring human body as far as possible, this utility model also provides further scheme: guide wire 3 adopts the elastic memory material, and an end of inserting splanchnocoel is the uncinate gyrus shape.Guide wire 3 adopts the elastic material with definite shape memory character, then can when not applying external force, keep an end to be the uncinate gyrus shape, when needs pass piercing needle 2, can keep of short duration straight shape again, recover the uncinate gyrus shape again when breaking away from piercing needle 2, in order to avoid too sharply stab human body viscera.During concrete enforcement, guide wire 3 can and wrap in the outer fine and closely woven spring of inner core by the metal inner core and constitute, and elasticity is realized that by fine and closely woven spring Memorability is then realized by the metal inner core.Referring to Fig. 6, because piercing needle 2 diameters are less, for the ease of guide wire 3 is inserted piercing needle 2, this utility model embodiment three be provided with can the back-shaped attitude of of short duration correction guide wire end hook straight shape pipe 7, in fact only need guide wire 3 is inserted in straight shape pipe 7, it is more straight that therefore the end of uncinate gyrus shape will become, and immediately it sent into puncture needle tubing 1, just can be than being easier to by piercing needle 2, and can not influence and recover the uncinate gyrus form when breaking away from piercing needle 2.
In order to avoid injuring human body as far as possible, the end that also indwelling flexible pipe 5 can be inserted splanchnocoel is designed to be the closing in shape, and the curve requirement is slick and sly, relatively in order to avoid touch the body internal organs of hurting sb.'s feelings.It should be noted that because indwelling flexible pipe 5 is softish, place the intravital part of people might not be illustrated in figure 4 as straight shape, and might change form, therefore can not make patient do not feel like oneself with patient activity.Keep somewhere flexible pipe 5 and can adopt harmless material---silica gel medically commonly used, experimental results show that length is comparatively suitable about 10cm, guide wire 3 is long so that extract, can be about 20cm.
This utility model embodiment is provided with the into medicine mouth mouth 4 that draws water in the tubing string side of puncture needle tubing 1, can connect the normal injection needle tubing, injects or drawing liquid when piercing needle 2 is in human body, so that can treat in passing during first inserting needle.Also can the into medicine mouth mouth that draw water more than be set during enforcement, so that draw water into medicine operation flexibly in the part of indwelling flexible pipe 5 outside human body.If only the into medicine mouth mouth that draws water is set, can be set directly at and keeps somewhere the end of flexible pipe 5 outside human body; A plurality of as if being provided with, then can draw in the tube wall side of keeping somewhere flexible pipe 5 with reference to the mode of puncture needle tubing 1.And the mouth mouth and the into medicine mouth mouth that draws water that puncture needle tubing 1 penetrates for guide wire 3, and the into medicine mouth mouth that draws water of keeping somewhere flexible pipe 5, be made as identical standard-sized syringe interface, then can adopt the normal injection needle tubing of same specification to connect use, make things convenient for medical personnel to prepare to treat equipment.During concrete enforcement, these interfaces can be equipped with links such as screw thread, bayonet socket according to the situation of injection needle.This utility model embodiment three also is provided with in the horn-like interface that puncture needle tubing 1 penetrates for guide wire 3 and can is made puncture needle tubing 1 airtight relatively by straight shape pipe 7 diaphragm seals of breaking 8, can strengthen the health reliability before Centesis instrument uses.
