Description

A kind of dilator with the folded utricule of receipts

Technical field

The present invention relates to medicine equipment consumptive material field, a kind of biofacies for prostate Dilation is related in particular to Capacitive dilator.

Background technology

Hyperplasia of prostate has turned into the common disease for threatening elderly men health, so-called hyperplasia of prostate, mainly due to preceding The hyperplasia of row glandular tissue, causes its volume to increase, and then extrudes the organ of surrounding, causes urinary tract to diminish and narrows, so as to row occur Urine is difficult, enuresis nocturna is frequent, urination time extension, the symptom such as vesical tenesmus, at present to the disease without effective prevention method.And Treating the method for hyperplasia of prostate has drug therapy, open operation treatment and minimally-invasive treatment.Drug therapy can allow prostate to increase Raw development slows down, or even some medicines can reverse the hyperplasia of prostate of some patientss.But the price of drug therapy is held high It is expensive, and some patientss are to being finally also not fee from operative treatment.What traditional prostatectomy or electrocision effect was to determine, But operation hits larger to patient, and the old person and the ability to bear at heart to operation are poor, and many patients are unwilling Undergo surgery.Whether which kind of mode, be required to the instrument and equipment of costliness, and need the long period to train, be skilled in technique Specialist completes.These conditions cause that basic hospital is difficult to carry out, and also medical resource can be caused to waste, and increased trouble Person's medical treatment cost.

It is to be fabricated to utricule using latex material that existing prostate expands treatment, and the design of the material is considered as far as possible The influence to patient wound is reduced, but the plasticity of the material is poor, and intermediate expansion expands more than two ends after filling, and is expanded in prostate Reduced in treatment and expand effect.And the material is opaque, it is impossible to carry out intubation positioning, therefore operation peace with reference to endoscopic apparatus Full property is difficult to ensure.

Further, since dilator needs to be inserted directly into patient's body, because utricule forms irregular prominent on main pipe surface Rise, especially assemble during insertion and form bulb in rear end, secondary insult can be brought to patient wound during intervention.

Utility model content

Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of transparent, biofacies Capacitive utricule high type dilator stacked to be received, utricule volume is reduced to reduce the wound to patient by receiving folded realization.

Technical scheme：To achieve the above object, it is of the present utility model a kind of with the dilator for receiving folded utricule, including master Body, on main pipe at least one can fill utricule and located at main pipe's inwall and through liquid injection port and utricule inner chamber The feed tube of connection；The utricule internally forms the folded shape of some gauffers rule rotations under vacuum state, is set outside gauffer There is tight bundle.

Utricule described in the utility model is the film-type utricule that TPU materials are made.The full name of TPU materials is thermoplastic poly ammonia Ester body, the material has outstanding advantages in following performance：Plasticity, wearability, transparency, elasticity, mechanical strength, high temperature resistance With inoxidizability, resistance to tortuosity, nontoxicity etc..Therefore it is to expand to split full ideal material for prostate.Particularly TPU film After utricule is full, because the limitation of TPU balloon shapes will not deform, therefore position and the journey of expansion can be as requested formulated Degree.Preferably, the utricule is cylindricality or fusiformis or elliposoidal.

Further, as prioritization scheme of the present utility model, balloon shapes are cylinder.In view of reduction to human body Damage, the cylinder with fillet before and after being shaped as of the utricule.It is based on human prostate tissues using cylindrical balloon Shape and expansion need formulate.It is mostly that intermediate expansion degree is more than because prior art is because of the limitation of material and technology Two ends degrees of expansion, therefore it is unsatisfactory, it is necessary to repeatedly full expansion realization to expand effect.And the utility model passes through fillet post Shape utricule, can also realize expanding effect well from two ends.

The folded mode of its rotation of the gauffer of the present utility model principle folded to umbrella receipts is similar, further, the ridge of the gauffer Line and main pipe's axis parallel；Gauffer at utmost reduces the damage to patient according to receiving folded clockwise or counterclockwise.Gauffer Rotation it is folded be to process to realize in production packaging process.

The utricule thickness is 0.05-0.2mm, preferably 0.05-0.1mm, to the parameter request of utricule its in 4 air Will not deform and rupture under pressure is full.

The tight bundle includes but is not limited to the PVC film band of heat seal bonding, is processed through heat seal when dispatching from the factory, and tight bundle will wrinkle Pleat is tightly held onto, it is necessary to tear tight bundle when using.

Beneficial effect：It is high, plastic that dilator of the present utility model is made high intensity, biocompatibility using special material Property good utricule, and make utricule enter line discipline by production and processing to revolve folded, at utmost reduce utricule volume and reduction is to patient Wound.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the utility model utricule rotation folded by the schematic cross-section under tight pencil state.

Specific embodiment

The utility model is further described below in conjunction with the accompanying drawings.

Embodiment 1

As shown in Figure 1 and Figure 2, it is a kind of with the dilator for receiving folded utricule, including main pipe 1, on main pipe extremely Lack a TPU utricule 20 that can be filled and located at main pipe's inwall and through liquid injection port and the feed tube 30 of utricule inner space； Utricule 20 is shaped as cylindrical and front and rear with fillet.The thickness of utricule 20 is preferably 0.05-0.2mm, and the parameter to utricule 20 will Asking it will not deform and rupture in the case where four atmospheric pressure are full.

Utricule 20 internally forms the folded shape of the rule rotation of some gauffers 4 under vacuum state, and tight beam is provided with outside gauffer Part 5.The crestal line 41 of gauffer 4 and the axis parallel of main pipe 1；Gauffer 4 at utmost reduces according to receiving folded clockwise or counterclockwise Damage to patient.It is to process to realize in production packaging process that the rotation of gauffer 4 is folded.Tight bundle 5 is heat seal bonding PVC film band, processes when dispatching from the factory through heat seal, and tight bundle 5 tightly holds onto gauffer, it is necessary to tear tight bundle when using i.e. Can.

Embodiment 2

As shown in Figure 1 and Figure 2, the present embodiment is substantially the same manner as Example 1, difference be 20 points of utricule be preceding capsule 21 and after 22 two, capsule.Main pipe be located at it is preceding it is intracapsular be provided with preceding liquid injection port 12, and be communicated to preceding feed tube 31, stretched out from main pipe rear portion； Main pipe be located at it is rear it is intracapsular be provided with rear liquid injection port 13, and be communicated to rear feed tube 32, stretched out from main pipe rear portion.

Utricule thickness is 0.05-0.1mm, and to the parameter request of utricule, it will not deform in the case where 4 atmospheric pressure are full And rupture.

The above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
