Abstract
The utility model discloses a kind of kidney mirror puncture sheath being provided with dilator, have the models such as F16, F18, F20, F24, comprise kidney mirror puncture sheath and dilator, described dilator is located in described kidney mirror puncture sheath cover; At the passage that described kidney mirror puncture sheath is parallel with dilator with being provided with the sheath that to puncture with kidney mirror between described dilator, described passage can communicate with kidney aggregation system.This utility model device is built-in with passage, external manograph.In percutaneous renal puncture process, by this passage water outlet situation, can determine whether puncture sheath accurately arrives aggregation system.In percutaneous nephroscope lithotripsy process, can through this channel conductance pressure, the pressure in Real-Time Monitoring renal pelvis, thus the adjustment carrying out necessary renal pelvis perfusion pressure, effectively can prevent the generation of urine source property pyemia.
Description
Technical field
This utility model relates to a kind of field of medical article technology, more specifically, relates to a kind of kidney mirror puncture sheath being provided with dilator.
Background technology
PCN technology (PCNL) is a pith of intracavity urological surgery, in treatment upper urinary stone, jointly become modern main Therapeutic Method with Ureteroscopy and extracorporeal shock-wave lithotripsy (ESWL), revolutionize the surgical intervention mode of conventional therapy.By integrated conduct methods such as Percutaneous nephrolith-otomy, ureteroscope lithotomy and extracorporeal shock-wave lithotripsys, more than 90% renal calculus can be made to exempt open operation.Patient takes ventricumbent position, routine disinfection drape, and the lower puncture needle in B ultrasonic location penetrates left lower calyx, then uses dilator dilated penetration point, inserts kidney mirror and ultrasonic adsorption system.
Whether, be generally need dilator exit, see if there is current and out judge whether puncture sheath is in place if, but after inserting dilator, the space of renal fibroblast sheath is otherwise fully engaged, cannot be in place by real-time judge renal fibroblast sheath.If in renal fibroblast sheath put procedure, renal fibroblast sheath enters into kidney aggregation system, namely there are flowing out, the effect that renal fibroblast accurately places puncture sheath just greatly can be improved.Meanwhile, put in sheath process, due to the displacement up and down of kidney, sheath may be caused to cross dark or excessively shallow, cause injury of kidney or need repeatedly to put sheath.And in rubble process, cannot pressure in Real-Time Monitoring renal pelvis.Renal pelvis inner high voltage (>30cmH
2o) be the main cause of urine source property pyemia.
Utility model content
The technical problems to be solved in the utility model for existing technical deficiency, provide a kind of safety, structure simple, can determine whether puncture sheath arrives aggregation system in time, and detect PCN puncture sheath and the dilator thereof of Renal pelvic pressure power.
Above-mentioned purpose of the present utility model is achieved by the following technical programs:
There is provided a kind of kidney mirror puncture sheath being provided with dilator, comprise kidney mirror puncture sheath and dilator, described dilator is located in described kidney mirror puncture sheath cover; At the passage that described kidney mirror puncture sheath is parallel with dilator with being provided with the sheath that to puncture with kidney mirror between described dilator, described passage can communicate with kidney aggregation system.
Preferably, described passage comprises protuberance and the recess suitable with protuberance, detects the pressure in renal pelvis by protuberance.
Preferably, described protuberance is arranged at described kidney mirror puncture sheath, and described recess is arranged at described dilator.
Preferably, described protuberance is arranged at described dilator, and described recess is arranged at described kidney mirror puncture sheath.
Compared with prior art, this utility model has following beneficial effect:
This utility model, on existing kidney mirror puncture sheath architecture basics, devises built-in passage aisle.In percutaneous renal puncture process, by this passage water outlet situation, can determine whether puncture sheath accurately arrives aggregation system.In percutaneous nephroscope lithotripsy process, can through this channel conductance pressure, the pressure in Real-Time Monitoring renal pelvis, thus the adjustment carrying out necessary renal pelvis perfusion pressure, effectively can prevent the generation of urine source property pyemia.
This utility model apparatus structure is simple, and without the need to increasing additional components, preparation cost is low.

Fig. 1 is this utility model preferred embodiment dilator schematic diagram.
Fig. 2 is this utility model preferred embodiment dilator schematic cross-section.
Fig. 3 is this utility model preferred embodiment kidney mirror puncture sheath schematic diagram.
Detailed description of the invention
This utility model embodiment accompanying drawing, only for exemplary illustration, can not be interpreted as restriction of the present utility model.In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.Below in conjunction with drawings and Examples, the technical solution of the utility model is described further.
Embodiment 1
The present embodiment provides a kind of kidney mirror puncture sheath being provided with dilator, and as shown in Figures 1 to 3, comprise dilator 1 and kidney mirror puncture sheath 3, described kidney mirror puncture sheath 3 is interspersed in dilator 1; Described kidney mirror puncture sheath 3 outer wall is provided with the protuberance 4 being parallel to kidney mirror puncture sheath 3; Described dilator 1 is correspondingly provided with the recess 2 being parallel to dilator 1 that can hold described protuberance 4, and protuberance 4 is contained in recess 2.
This utility model, on existing kidney mirror puncture sheath architecture basics, devises built-in passage aisle.In percutaneous renal puncture process, by this passage water outlet situation, can determine whether puncture sheath accurately arrives aggregation system.In percutaneous nephroscope lithotripsy process, can through this channel conductance pressure, the pressure in Real-Time Monitoring renal pelvis, thus the adjustment carrying out necessary renal pelvis perfusion pressure, effectively can prevent the generation of urine source property pyemia.This utility model apparatus structure is simple, and without the need to increasing additional components, preparation cost is low.
