Abstract

The utility model relates to a netted prop-sheath sealed-hole of prostate and urethra measuring device. The utility model comprises a head part, a saccule part, a guide pipe, and a guide pipe body at the tail part. The guide pipe is communicated with the saccule via a concave hole, and the tail part of the guide pipe is provided with a piston or a one-way valve. The piston or the one-way valve is favorable for a prop sheath to quickly and safely enter into the urethral orifice to measure the length of the rear urethra and to do positioning of urethral pathologic change during urethroscopy. The utility model has the advantages of simple structure, easy use, exact measure, etc.

Description

Prostate network sheath closed pore and urethrometer

This utility model belongs to the Urology Surgery medical apparatus and instruments.

Prostate network treatment hyperplasia of prostate is the domestic new technique of the nineties, and corresponding apparatus is not perfect, lacks network closed pore and urethrometry apparatus in the market.Prostate network sheath front end is concordant, often is difficult for entering urethral orifice in operation, and examination is inserted and not only prolonged operating time repeatedly, and the generation of easy damaged urethral orifice mucosa is hemorrhage, even causes operative failure.The measurement of back urethra exact length is a foundation of selecting the respective length network, also is the operation key of success.The Transrectal Ultrasound measurement method of present clinical usefulness is indirect measurement, need special installation and know-how personnel operation, and measured value does not have the direct method of measurement accurate.Look into association area such as patent gazette and there is no urethrometry and network sheath obturator.

The purpose of this utility model provides a kind of simple in structure, and is easy to use, measures accurately, is beneficial to prostate network sheath closed pore and urethrometer that the guide support sheath enters the Urina Hominis road junction rapidly and safely.

The purpose of this utility model is achieved in that a kind of prostate network sheath closed pore and urethrometer, its primary structure is made up of head, sacculus portion, conduit, afterbody, conduit is provided with pit-holes 2 near head 1 place, sacculus 3 rings are tied on the conduit 4, sacculus 3 with communicate with conduit 4 by pit-holes 2, catheter tail 6 is a piston 7.Conduit 5 between catheter body sacculus portion 2,3 and afterbody 6 indicates the sign pipe 5 of measuring length for being provided with.Sacculus 3 is made by the tubulose sealed rubber membrane.Piston 7 is a check valve.

Because the air bag of being made up of air bag and pit-holes is set, can make the metal tack of sheath mouth become smooth, resilient semicircular bodies after it is full, help the guide support sheath and enter urethral orifice rapidly and safely.Owing on the conduit sign is set, can be used for urethral length and measure, can in art, operate by operator, method is simple, and measured value is accurately and reliably.

Below in conjunction with drawings and Examples this utility model is further described.

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the full state diagram of sacculus;

Fig. 3 has been that obturator is done the time spent state diagram.

Among the figure 1, head, 2, pit-holes or passage, 3, sacculus, 4, conduit, 5, indicate, 6, catheter tail, 7, piston, 8, the support sheath.

The long 45cm of this apparatus, external diameter 1.7mm is equivalent to F5 ureteral catheter external diameter, and internal diameter is not limit.Make by no-toxicity medical silicone rubber or plastics.Be divided into head 1, long 1cm, sacculus portion 2,3 indicate pipe 4,5 and afterbody 6 for 1.5cm length.Indicate pipe 5 from sacculus tail side counting, give labelling with the red line bar every 1cm; Per therebetween 112 spacings are tagged to till the 20cm with black line.Afterbody is a piston 7, communicates with sacculus 3 in sacculus 3 middle parts through sign pipe 4,5 openings 2 of piston 7 by hollow.Sacculus 3 is made by the tubulose sealed rubber membrane, is not close to during water-filling to indicate pipe 4,5.Sacculus is filled after afterbody piston 7 injects Sterile Saline.

Be used for network sheath 8 and play the obturator effect: earlier this apparatus is inserted prostate network sheath 8 outer 0.5cm, it is an amount of to inject Sterile Saline through tail end piston 7 again, make the lucky chimeric sphere that becomes of 8 mouthfuls in sacculus 3 and support sheath, can make support sheath 8 smoothly enter urethral orifice by lubricant this moment.Treat that support sheath 8 enters emptying sacculus 3 behind the urethra fully, takes out this apparatus.

Measure urethral length: after inserting urethrocystoscope, insert urethrometer from intra-ureteral cannula mirror opening and enter bladder, inject 5 milliliters of Sterile Salines through tail end piston 7 then and make sacculus 3 full, gently draw sign pipe 5, sacculus 3 promptly to be close to the neck of bladder opening.This moment, urethrocystoscope was withdrawed from the limit, and the limit is observed and indicated pipe 5 high scales to the seminal colliculus place, can record the exact length of prostate-urethra; Retreat to the urethra lesion and can record the length of pathological changes, and can measure the scope of pathological changes apart from internal urethral orifice.

By all once successes of 65 routine clinical uses, wherein 15 routine network implantations and 50 routine urethroscopys, success rate reaches 100%.
