Description

A kind of negative pressure adjusting device being connected with ureter sheath
Technical field
The present invention relates to a kind of medicine equipment, more particularly to a kind of negative pressure adjusting device being connected with ureter sheath.
Background technology
With growth in the living standard, people's diet structure also occurring to change, the patient of upper urinary stone by Year increases, wherein especially with kidney stone patient as very.At present the operative treatment mode of main flow have Jing nature passages (i.e. urethra, bladder, Ureter) take the non-natural passage rubble such as stone and percutaneous kidney fistulization as operation pathway rubble and take stone, due to Jing it is non-natural logical Road rubble takes stone to be had massive haemorrhage, renal function destruction and damages the complication such as surrounding tissue organ, and medical circle is gradually in recent years High praise carries out kidney stone operation as operation pathway using natural passage (i.e. urethra, bladder, ureter).
When Jing nature passages carry out kidney stone operation, Jing nature passage piece ureter sheath of indwelling is needed in art as operation Passage, is performed the operation so that ureteroscope can quickly pass in and out kidney with Jing ureter sheaths, it is to avoid repeatedly turnover is caused to ureter Damage, while operating time can be shortened, improve the security of operation.Ureteroscope is inserted in Jing ureter sheaths to be entered with Bladder stone When row kidney stone rubble is performed the operation, Jing ureteroscopes are needed constantly to pour flushing liquor, to keep getting a clear view, but, constantly pour into kidney Flushing liquor in dirty aggregation system, increases the less kidney aggregation system pressure of volume, and as the ureter of drainage channel Finite gap between mirror and ureter sheath, and pipeline is longer, self-draining effect is poor, and kidney is easily caused in surgical procedure Dirty aggregation system high pressure, causes damage to kidney, particularly with kidney stone concurrent infection patient, there is also bacterium and toxin enters Enter the situation of blood circulation system, cause the sexy dye in urine source, patient's life when serious, may be jeopardized;On the other hand, laser lithotripsy Calculus powder and disintegrating slag produced by art can affect surgical field of view, need repeatedly broken with calculus catching net-like means or lithotomy forceps taking-up calculus Slag, thus have impact on procedure efficiency, extends operating time, increased operation risk.
In view of the foregoing,《Urological diseases diagnoses and treatment guide》In mention:Domestic Jing natures passage is used as operation Path treatment kidney stone is not recommended for process the first-selected treatment method more than 2cm calculus;It means that more than the calculus of 2cm, It is not suitable for using this operation method.But nonetheless, for the kidney stone less than 2cm takes out operation, using this operation Method is still easy to the high situation of kidney aggregation system pressure occur, causes urine source property infection rate high, affects the operation The development of mode.
Accordingly, it is capable to the internal pressure of no effective control kidney aggregation system, for raising Jing nature passages are used as operation road The security of footpath treatment kidney stone operation is particularly important, and for the clear visual field can be provided in art and quick calculus is effectively removed Powder disintegrating slag, to ensure that operation is rapidly completed and ensures that surgical effect is all significant.
The content of the invention
To solve the problems, such as prior art, the present invention provides a kind of negative pressure adjusting device being connected with ureter sheath.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of negative pressure adjusting device being connected with ureter sheath, the device include that the sealing being connected with ureter sheath end is connected Joint, joint for sealing connecting inner hollow form cavity, offer connector, the connection negative pressure suction for connecting the ureter sheath thereon The negative pressure access port of leading-in device, for the ureteroscope mirror body access port for penetrating and the air inlet for being provided with air inlet adjustment valve, air inlet Regulating valve is realized adjusting the vacuum magnitude in cavity by changing the gas channel size between cavity and air;Mirror body connects Porch is provided with closure, and the elastic packing with the tube outer wall sealing cooperation of ureteroscope is provided with the closure Hole;The air inlet adjustment valve includes the regulation for being arranged on the valve seat and valve seat outer wall suit at the air inlet of the joint for sealing connecting Knob, the valve seat wall offer louver(-vre), and the adjusting knob inwall offers the air channel coordinated with the louver(-vre), By rotating the adjusting knob, the control louver(-vre) is aligned or being offset with air channel, to change the cavity and air Between gas channel size, realize adjust cavity in vacuum magnitude;The tip side wall of the valve seat extends pointer, correspondence Louver(-vre) position, is provided with pointer chute at the top of the adjusting knob, by pointer in the pointer chute location May determine that louver(-vre) is aligned with air channel or degrees of offset is so as to the negative pressure for obtaining needing;The two ends phase of the pointer chute There is angle to Pivot axle.
Be correspondingly arranged at the valve seat and the air inlet barb and draw-in groove the valve seat is fixedly connected on it is described close At the air inlet of envelope connector.
The closure includes Thin Elastic glue and friction top, and the elastic packing hole position is on the Thin Elastic glue, described Friction top is pressed abd fixed on the Thin Elastic glue at the mirror body access port.
The invention has the beneficial effects as follows:The negative pressure adjusting device of the present invention is connected with ureter sheath by joint for sealing connecting, And be provided with the mirror body access port that penetrates for ureteroscope, the connector of ureter sheath, the negative pressure of connection negative pressure suction device and connect The space that cavity composition in entrance, the air inlet for being provided with air inlet adjustment valve, above-mentioned each mouth and joint for sealing connecting is interconnected, When the mirror body access port that ureteroscope penetrates joint for sealing connecting carries out kidney stone performs the operation, the space is formed a sealing Service aisle, can adjust air inlet adjustment valve to control vacuum magnitude in cavity in art as needed, Jing ureteroscopes can be noted Enter gap between the liquid Jing ureteroscopes of kidney aggregation system and ureter sheath fast from the negative pressure interface channel of negative pressure adjusting device Speed is suctioned out, effective control kidney aggregation system pressure, it is to avoid kidney aggregation system high pressure causes to endanger patient, it is ensured that the safety of operation Property, at the same time it can also the calculus powder that produces in quick exsuccation and disintegrating slag, surgical field of view definition is improved, effectively remove knot Stone, it is to avoid the poorly efficient calculus catching net-like means of Reusability or lithotomy forceps, makes procedure efficiency higher, and operating time is shorter, and operation safety is more It is high;What is more important:The raising of the combination property allows the calculus more than 2cm more to adopt Jing nature passages as hand The processing mode in art path, it is to avoid the multiple complications for being taken stone and being brought using the non-natural passage rubble such as percutaneous kidney fistulization, makes The scope of application that the operation pathway processes calculus is more extensive, brings Gospel to extensive patients.
Description of the drawings
