Description
Technical field
The present invention relates to medicine and hygiene fields, relate in particular to a kind of expansion for prostate dilation operation and split closed flood pattern.
Background technology
Prostatic hyperplasia is the common disease of middle-aging male, traditional therapy adopts open surgery to cut prostata tissue, prostate dilation operation replaces traditional open surgery gradually in recent years, becomes a kind of and solves the Therapeutic Method that prostatic hyperplasia enjoys recommendation.Prostate dilation operation is by prostate dilator is inserted patient's prostatic urethra, utilizes the full mode of sacculus water filling to treat.But one of this technology large difficult point is at present, water filling sacculus lacks biocompatibility, and patient uses sense of discomfort higher; By syringe manually to injecting normal saline in sacculus, owing to being subject to very big resistance (about 2 ~ 3 atmospheric pressure), water filling job very difficult, jumbo syringe is adopted to be difficult to water filling, although and adopt the syringe of low capacity to reduce water filling difficulty, but frequently will draw normal saline and water filling, workload is very large, and during the course because frequent fluid injection may have the risk of postoperative infection.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of can realize under enclosed environment imbibition, continue fluid injection prostate expand split closed flood pattern.
Technical scheme: for achieving the above object, a kind of prostate of the present invention expands and splits closed flood pattern, comprises a two capsule dilator, the first three-way valve, the second three-way valve, feed tube, syringe pump, the liquid injection pipe that is connected with syringe pump; The described pair of capsule dilator comprise main pipe, parcel main pipe leading section the first sacculus and the second sacculus, insert main pipe's tube chamber and the first syringe is communicated with the first sacculus and insert main pipe's tube chamber and the second syringe be communicated with the second sacculus, main pipe's correspondence the first sacculus and the second sacculus are respectively equipped with the first perforate and the second perforate.
Wherein two interfaces of described first three-way valve connect liquid injection pipe and the first syringe respectively, and wherein two interfaces of the second three-way valve connect feed tube and the second syringe respectively, and the first three-way valve and the second three-way valve separately a remaining interface are interconnected.
Described syringe pump comprises housing, piston body, piston body and housing form injecting cavity, Pressure gauge is communicated with in injecting cavity, hull outside is provided with the self-locking mechanism that limited piston body retreats, and piston body comprises cylindrical body, piston head, connection piston head the swing handle of the screw rod coordinated with cylindrical body and screw rod end.The improvement of syringe pump can make water filling convenient, efficient.When starting water filling, because sacculus is not quite intrinsic pressure, being subject to body cavity extruding also little, therefore utilizing the mode of piston body pushed forward to realize efficient water injection.When water filling reaches a certain amount of, sacculus intrinsic pressure more than 2 atmospheric pressure time, piston has been difficult to push ahead, now use instead swing handle rotate mode, utilize screw rod by piston head pushed forward.Owing to being provided with self-locking mechanism, therefore piston body itself can not flick because of the pressure in injecting cavity.Described syringe pump volume is 100 ~ 200ml, minimum scale 10 ~ 30ml.
The present invention first three-way valve and the second three-way valve are respectively equipped with the position-limit mechanism the first three-way valve or the second three-way valve only switched under two kinds of open-circuit conditions; When the first three-way valve switch is in 1-A state: formed between liquid injection pipe and the second three-way valve and uniquely open a way, when the first three-way valve switch is in 1-B state: formed between liquid injection pipe and the first syringe and uniquely open a way; When the second three-way valve switch is in 2-A state: formed between the first three-way valve and feed tube and uniquely open a way, when the second three-way valve switch is in 2-B state, formed between the first three-way valve and the second syringe and uniquely open a way.
Of the present invention pair of capsule dilator is preferably " the two capsule in front and back " type, and described first sacculus and the second sacculus are arranged in order before and after main pipe leading section.But other pair of bellows dilator also belongs to protection scope of the present invention under based on the principle identical with the present invention.
In order to improve convenience and the safety of use, the liquid feeding end of described feed tube is provided with vein puncture head, directly can use by puncturing with normal saline infusion bottle or transfusion bag.Feed tube can also arrange flow-stopping clip or current-limiting apparatus as required.
The method that product of the present invention uses is: when preparing injection, be connected with the first syringe of two capsule dilator, liquid injection pipe, the second three-way valve respectively by three of first three-way valve interfaces, remaining two interface of the second three-way valve are connected with the second syringe of two capsule dilator, feed tube respectively.The liquid feeding end of feed tube is connected with vein puncture head, inserts normal saline transfusion bag; The liquid feeding end of liquid injection pipe connects syringe pump.
First three-way valve is switched to 1-A state, when second three-way valve is switched to 2-A state, unique path is formed between liquid injection pipe to feed tube, now extract syringe pump, the normal saline in transfusion bag is successively in the injecting cavity of feed tube, the second three-way valve, the first three-way valve, liquid injecting pipeline syringe pump.Then the second three-way valve is switched to 2-B state, advance syringe pump, normal saline in injecting cavity just rushes liquid through liquid injection pipe, the first three-way valve, the second three-way valve, the second syringe successively in a sacculus, utilize the swing handle of syringe pump to operate when resistance is excessive, until meet full requirement; Then the first three-way valve is switched to 1-B state, in the first syringe, fluid injection fills another sacculus, until meet the demands.Whole system does not need separated by all parts and reconnect in the process of imbibition, switching pipeline, fluid injection, maintains in a closed system, not only easy to operate, and safety and sanitation.
Beneficial effect: two capsule dilator is configured in a closed water filling system by the present invention, can carry out fluid injection respectively, not only provide the surgical environments of safety and sanitation, also ensure high efficiency and the convenience of fluid injection, make injection volume precisely controlled to two sacculus.
