Abstract
The utility model discloses a retroperitoneoscopy dilator which comprises an air bag, an inflator pump, a pressure tester and a three-way valve. The air bag is used for being arranged in a retroperitoneum, the inflator pump is used for inputting air into the air bag, the pressure tester is used for detecting air pressure capacity in the air bag, the three-way valve is used for being communicated with an inflating and deflating channel and connected on an output pipeline of the inflator pump, and the tail end of the output pipeline is divided into two branches which are communicated with the air bag and the pressure tester respectively. The air bag is arranged in the retroperitoneum, a user extrudes the inflator pump outside with hands, the air is made to enter the air bag and the pressure tester, the preset air can be inflated into the air bag according to needs, the air bag is expanded, the surgical operation space of the retroperitoneum is expanded, therefore, a doctor can perform surgery conveniently, the difficulty of the surgery is lowered, and surgical time is saved.
Description
Technical field
This utility model relates to pneumoretroperitoneum field of surgery, especially a kind of Retroperitoneoscopicvaricocelectomy dilator.
Background technology
Prior art to the kidney in pneumoretroperitoneum carry out Minimally Invasive Surgery time, because the space of pneumoretroperitoneum is narrower and small, operation device is treating that operative region cannot put to good use, be not easy to doctor's operation, affect doctor's judgement, operating time is elongated, had operation safety hidden danger simultaneously.
Someone inserts after pneumoretroperitoneum with water pocket, by water pump (as syringe), the water of scheduled volume is injected in water pocket, water pocket volume is expanded, pneumoretroperitoneum is strutted, there are the following problems for this structure with water pocket: water flow velocity is spent slowly, regardless of being injected water or water being extracted from water pocket, all needs the regular hour, impact operation efficiency, makes troubles to doctor.
Patent name is that the patent of invention that the self-enclosed balloon dilator of a kind of pneumoretroperitoneum, patent publication No. are 103263723A discloses a kind of dilator, and it has adopted numerous mechanical parts, and the connection more complicated between mechanical part is loaded down with trivial details.
Utility model content
It is narrow and small that the purpose of this utility model is to overcome the interior operative region of prior art pneumoretroperitoneum, make the technical problem of operation technique difficulty, provide a kind of and can effectively expand the operative region in pneumoretroperitoneum, increase operative space, a kind of Retroperitoneoscopicvaricocelectomy dilator that facilitates doctor to perform the operation.
For realizing above object, this utility model has been taked following technical scheme: Retroperitoneoscopicvaricocelectomy dilator, comprise the air bag for being placed to pneumoretroperitoneum, be used to the inflator pump of air bag input gas, for detection of the pressure tester of gas pressure amount of capacity in air bag, for being communicated with and switching the three-way valve of inflation bleed passage, described three-way valve is connected on the output pipe of described inflator pump, output pipe terminal is divided into two branch roads, is communicated with respectively with described air bag and pressure tester.
Described pressure tester is provided with testing needle, and testing needle one end extend in pressure tester, and the other end is provided with tolerance scale.Testing needle can be ejected by the gas pressure of pressure tester, inflator pump is carried how much gas of coming, and just has great the blowing pressure, thereby make testing needle indicate corresponding scale in air bag, show pressure size in air bag, help doctor to understand the related data information such as operative space.
Compared with prior art, tool has the following advantages this utility model: by air bag is placed in pneumoretroperitoneum, user is at external hands extruding inflator pump, make gas enter into air bag and pressure tester, air bag can pour predetermined gas as required, makes air bag expansion, by the operation technique space enlargement of pneumoretroperitoneum, thereby facilitate doctor to perform the operation, reduced the difficulty of operation, saved operating time, and this utility model has been simple in structure, cost is low, is not easy to damage.
Accompanying drawing explanation
Fig. 1 is this utility model Retroperitoneoscopicvaricocelectomy dilator air bag unaerated structural representation;
Fig. 2 is the structural representation after Retroperitoneoscopicvaricocelectomy dilator airbag aeration in Fig. 1;
Fig. 3 is the three-way valve structure for amplifying schematic diagram in Fig. 1 and Fig. 2.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, content of the present utility model is described in further details.
Embodiment:
Refer to shown in Fig. 1 and Fig. 2, Retroperitoneoscopicvaricocelectomy dilator, comprise air bag 1, it is for being placed to pneumoretroperitoneum, and inflator pump 2 is used to air bag 1 and inputs gas, and pressure tester 3 is for detection of gas pressure amount of capacity in air bag 1, three-way valve 4 is to inflate bleed passage for being communicated with and switching, the syndeton of above-mentioned parts is: three-way valve 4 is connected on the output pipe of inflator pump 2, and output pipe terminal is divided into two branch roads, is communicated with respectively with air bag 1 and pressure tester 3.
Incorporated by reference to consulting shown in Fig. 3, the concrete structure of the three-way valve 4 of the present embodiment is: three-way valve 4 comprises inflation entrance 41, gas vent 42, blowing mouth 43, and valve turns round 44, valve is turned round 44 vertical cross-sections and is provided with three through hole (not shown)s, can be according to the needs of inflation and venting, be communicated with inflation entrance 41 and blowing mouth 43, and gas vent 42, inflation entrance 41 is connected with inflator pump 2, the gas that blowing mouth 43 is come inflation entrance 41 is delivered to air bag 1 and pressure tester 3, gas vent 42 is for emitting gas, three-way valve 4 is turned round 44 rotation by valve and is connected the filling channel between inflation entrance 41 and blowing mouth 43, and the bleed passage of gas vent 42, valve is turned round 44 and be can be rotated to aeration modes specifically, now valve is turned round 44 two through holes that are arranged on the tube wall between inflation entrance 41 and blowing mouth 43 and is communicated with respectively inflation entrance 41 and blowing mouth 43, make to inflate between entrance 41 and blowing mouth 43 and connect, and being blocked in the opposite walls place relative with gas vent 42, the 3rd through hole cannot exit, when valve being turned round to 44 while rotating to venting pattern, wherein a through hole just in time communicates with gas vent 42, inflate between entrance 41 and blowing mouth 43 simultaneously and by valve, to be turned round 4 sealing wall and block and make to connect inflation.
The expansion size of air bag 1 need to be carried out the how many adjustment of aeration quantity according to different patients' pneumoretroperitoneum, pressure tester 3 is provided with testing needle 31, testing needle 31 one end extend in pressure tester 3, the other end is provided with tolerance scale, two scales are set conventionally, a scale 300mL, a scale 500mL, the gas being filled with when inflator pump 2 enters into pressure tester 3 when interior, testing needle 31 is extruded by the pressure in pressure tester 3, and the length that the number of the fill gas scale of construction just can be extruded by testing needle 31 finds out to have certain intuitive.
Above-listed detailed description is for the illustrating of this utility model possible embodiments, and this embodiment is not in order to limit the scope of the claims of the present utility model, does not allly depart from the equivalence that this utility model does and implements or change, and all should be contained in the scope of the claims of this case.
