Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of novel cyst puncture and intubation external member.
Background technology
Pure hepatic cyst or cyst of kidney are clinical common diseases.Often cause patient hepatic region or kidney district discomfort, and patient's Liver and kidney function even functional defect may be affected.Cyst suction under current clinical treatment many employings Image-guided and Sclerotherapy with anhydrous ethanol method, advantage is: wound is little, few intercurrent disease, outpatient service can the multinomial advantage such as operative treatment, makes Most patients no longer need to be in hospital or to carry out conventional large operative treatment.Its treatment principle be: a, be first suction cyst in liquid pressure-reducing; B, the dehydrated alcohol that reinjects melt cyst endotheliocyte, will no longer form new capsule liquid, thus reach the object of healing after endothelial cell damage.
At present coaxial metal puncture needle is often used to cyst of kidney row puncture sclerosis art.When cyst of kidney volume is larger, due to the depression effect of cyst after capsule liquid is aspirated, the position of kidney can change, cause puncture needle to be deviate from by cyst or cause the damage of excess of the kidney matter, in addition when under the contiguous diaphragm of cyst, respiratory movement is comparatively obvious, the metal needle of hard damages cyst wall probability when respiratory movement is larger, dehydrated alcohol can be caused to spill, cause the obvious pain of patient, affect therapeutic effect.Meanwhile, metal puncture needle tip only has a hole, and the tissue debris produced during Alcohol sclerotherapy can block pin hole, makes Endodontic failure.And the drainage kit assembly commonly used at present is more, expensive, inconvenient operation, caliber is also comparatively thick, the nephridial tissue that easily damage is more fragile.
Utility model content
This utility model provides a kind of novel cyst puncture and intubation external member, solves puncture needle in prior art and easily deviates from cyst position, and easily damages the technical problem of cyst wall.
The purpose of this utility model is achieved through the following technical solutions:
A kind of novel cyst puncture and intubation external member, comprise blue empty needle, hollow puncture needle, guide wire, metal canula, flexible catheter, wherein, described hollow puncture needle is connected with blue empty needle, be passage in the middle of push-pull bar on described blue empty needle, described passage can penetrate guide wire, metal canula and flexible catheter, the external diameter of described guide wire is less than the internal diameter of described metal canula, the internal diameter of described flexible catheter is greater than the external diameter of described metal canula, the external diameter of described flexible catheter is less than the internal diameter of described hollow puncture needle, and one end of described flexible catheter is pigtail type.
Technique effect of the present utility model is: effectively prevent the infringement of excess of the kidney matter and spilling of ethanol, opens and makes flexible catheter be not easy cyst, thus improves safety and the success rate for the treatment of.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of indigo plant control pin of the present utility model;
Fig. 2 is the structural representation that flexible catheter of the present utility model is inserted in metal canula and guide wire;
Fig. 3 is the structural representation of flexible catheter of the present utility model.
Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail this utility model below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Fig. 3, for the one novel cyst puncture and intubation external member that this utility model provides, comprise blue empty needle 1, hollow puncture needle 2, guide wire 3, metal canula 4, flexible catheter 5, wherein, described hollow puncture needle 2 is connected with blue empty needle 1, be passage 12 in the middle of push-pull bar 11 on described blue empty needle 1, described passage 12 can penetrate guide wire 3, metal canula 4 and flexible catheter 5, the external diameter of described guide wire 5 is less than the internal diameter of described metal canula 4, the internal diameter of described flexible catheter 5 is greater than the external diameter of described metal canula 4, the external diameter of described flexible catheter 5 is less than the internal diameter of described hollow puncture needle 2, one end of described flexible catheter 5 is pigtail type (as shown in Figure 3).
Wherein, as shown in Figures 2 and 3, the problem of needle point blocking during in order to effectively prevent cystosclerosis, there is multiple side opening 51 one end (one end of pigtail type) of described flexible catheter 5.In order to follow the tracks of under X-ray or ct fluoroscopy, locate, the material of guide wire 3 is stainless steel metal elastomeric material.Damage tissue smoothly and not to make guide wire 3 insert, the front end of described guide wire 3 is smooth round end.
In order to follow the tracks of under ct fluoroscopy, locate, in the tube wall of described flexible catheter 5, there is spiral metal wire.
Described novel cyst puncture and intubation external member, also comprises guide wire push-assisting device, broken skin cutter, dilator, entry needle and syringe, and wherein, puncture needle can be divided into 18,19G two kinds of specifications, most advanced and sophisticated sharp keen, is convenient to puncture in cyst; Guide wire push-assisting device can facilitate putting into broken skin cutter and can being used for cutting tough and tensile skin of seal wire, is convenient to expand skin; Dilator is used for expansion and puts tube passage; Metal canula 4 is metal hollow structure, and be placed in flexible catheter 5, it is harder, can be positioned in cyst with flexible catheter 5 along guide wire 3; Blue empty needle 1 tail end is the silica gel sealing body having hole, can insert guide wire 3, and can prevent air from entering.
This utility model in actual applications, when treatment is inhaled to the renal cystis note, can follow the trail of under ultrasonic or ct fluoroscopy, location, thrust cyst, after pumpback goes out capsule liquid with hollow puncture needle 1, guide wire 3 is put into through blue empty needle 1 tail end, extract puncture needle, utilize dilator to expand subcutaneous tissue, flexible catheter 5 is put to entering in cyst by recycling metal canula 4, then exit seal wire, then start treatment.Because flexible catheter 5 is softer, even if position is shifted, also excess of the kidney matter and cyst wall be can not damage, the infringement of excess of the kidney matter and spilling of ethanol also just avoided; Flexible catheter 5 far-end is pigtail type simultaneously, makes it be not easy cyst; Flexible catheter 5 far-end has multiple side opening, the problem of needle point blocking when effectively can prevent cystosclerosis.
Be understandable that, the system structure shown in figure does not form the restriction to system, can comprise the equipment more more or less than diagram, or combine some equipment, or different deployed with devices.
Above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
