Description
Technical field
Percutaneous Nephrotithotomy expander belongs to medical instruments field under a kind of direct-view of the present invention.More particularly to a kind of straight
Depending on lower Percutaneous Nephrotithotomy expander.
Background technique
Kidney stone is Urology Surgery common disease frequently-occurring disease, and the complicated renal calculis such as multiple, casting mold generally require operative treatment,
Percutaneous nephrolithotomy is most common lithotomy method.Current clinically common method is first with kidney puncture needle in skin
The predetermined point of puncture of skin is pierced into kidney aggregation system, then extracts needle core, the withdraw of the needle after needle tubing is put into guidance seal wire, with type from small to large
Number fascia dilator be gradually expanded to the models of needs, place corresponding skin kidney duct sheath, establish skin kidney channel, be then placed in defeated
Urinary catheter mirror enters kidney aggregation system, and rubble takes stone.This method expands the depth of pipe in process of expansion with preoperative Radiological measurement
And puncture needle paracentesis depth is judged as foundation, is easy to appear error, for avoid expanding it is too deep cause it is unnecessary damage and go out
Blood, general opinion is not peaceful shallow deep, but is likely to result in skin kidney duct sheath in this way and is difficult to be put into kidney aggregation system.In addition, some cases
It is narrow to suffer from kidney kidney calices neck, skin kidney sheath is difficult to pass through, and is forced through and is easy to damage kidney calices neck, leads to severe haemorrhage.
Summary of the invention
In place of avoiding the deficiencies in the prior art, and a kind of raising puncture fistula-building success rate is provided,
Reduce Percutaneous Nephrotithotomy expander under a kind of direct-view of bleeding.
The purpose of the present invention is what is reached by following measures, Percutaneous Nephrotithotomy expands under a kind of direct-view of the invention
Prop includes tube head, tube body, pipe tail three parts, and tube head front is cone, and the tip of tube head is round blunt shape, and skin kidney duct sheath can be with
It is put into tube body.
It is surgically prepared, puts operation position well after patient's anesthesia.Conventional percutaneous renal puncture pin puncture is put to aggregation system
Guidance seal wire is set, is gradually expanded with F8 ~ F16 fascia dilator, Percutaneous Nephrotithotomy expander under a kind of direct-view is then changed, it will
Percutaneous Nephrotithotomy expander puts on skin kidney duct sheath of corresponding size under a kind of direct-view, and ureteroscope is put into a kind of direct-view
In lower Percutaneous Nephrotithotomy expander, mirror front end with Percutaneous Nephrotithotomy expander tip is concordant under a kind of direct-view is
Can, under ureteroscope direct-view, in the case where guidance seal wire guides, clearly enter kidney aggregation system, can exit percutaneous under a kind of direct-view
Renal fibroblast dilator for fistulization leaves skin kidney duct sheath.
The present invention is a kind of percutaneous kidney dilator for fistulization that can be looked at lower expansion straight and place skin kidney duct sheath, is rapidly and accurately expanded
Skin kidney duct sheath is placed, tissue damage is reduced, reduces operative hemorrhage probability, improves procedure efficiency.
Detailed description of the invention
Attached drawing 1 is structural schematic diagram of the invention.
Attached drawing 2 is overall schematic of the invention.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
In figure: tube head 1, tube body 2, pipe tail 3, expansion tube core 4.
As shown in Fig. 1, Percutaneous Nephrotithotomy expander includes tube head 1, tube body 2, pipe under a kind of direct-view of the invention
3 three parts of tail, tube head front are cone, and the tip of tube head is round blunt shape, and lumen diameter is more than or equal to F10, can be put into routine
F7.5 ~ F9.0 ureteroscope, tube body are about 25 centimetres, and pipe diameter is any one in F18-F24, can be covered of corresponding size
Skin kidney duct sheath, it is accurate to grasp dimension and depth convenient for the lower expansion of direct-view, put skin kidney duct sheath well rapidly, about 0.5 li of tube head
Rice is long, shorter than general expander, and tube head is cone, and the tip end of tube head is round blunt shape, to reduce in process of expansion to group
The damage knitted.
As shown in Fig. 2, Percutaneous Nephrotithotomy expander includes tube head 1, tube body 2, pipe under a kind of direct-view of the invention
3 three parts of tail, tube head front are cone, and the tip of tube head is round blunt shape, and lumen diameter is more than or equal to F10, can be put into routine
F7.5 ~ F9.0 ureteroscope, tube body are about 25 centimetres, and pipe diameter is any one in F18-F24, can be covered of corresponding size
Skin kidney duct sheath, it is accurate to grasp dimension and depth convenient for the lower expansion of direct-view, put skin kidney duct sheath well rapidly, about 0.5 li of tube head
Rice is long, shorter than general expander, and tube head is cone, and the tip end of tube head is round blunt shape, to reduce in process of expansion to group
The damage knitted further includes an expansion tube core 4, and expansion tube core is slightly longer than tube body and can move in tube body, the expansion tube core energy
Tube body 2 is passed through from pipe tail 3 and slightly appears tube head 1, and it is equally in round blunt type that expansion tube core 1, which appears one end of tube head 1, is further reduced
To the damage of tissue in journey, the other end for expanding tube core 4 equally appears pipe tail, and expansion tube core 4 is additionally provided with 3 joint of pipe tail
One detent prevents expansion tube core 4 from excessively appearing tube head 1, expands in tube core and be additionally provided with interior conduit, said inner tube road can be for seal wire
Pass through, interior conduit caliber is 0.38mm.
It is surgically prepared, puts operation position well after patient's anesthesia.Conventional percutaneous renal puncture pin puncture is put to aggregation system
Guidance seal wire is set, is gradually expanded with F8 ~ F16 fascia dilator, Percutaneous Nephrotithotomy expander under a kind of direct-view is then changed, it will
Percutaneous Nephrotithotomy expander puts on skin kidney duct sheath of corresponding size under a kind of direct-view, and ureteroscope is put into a kind of direct-view
In lower Percutaneous Nephrotithotomy expander, mirror front end with Percutaneous Nephrotithotomy expander tip is concordant under a kind of direct-view is
Can, under ureteroscope direct-view, in the case where guidance seal wire guides, clearly enter kidney aggregation system, can exit percutaneous under a kind of direct-view
Renal fibroblast dilator for fistulization leaves skin kidney duct sheath.
