Abstract
The utility model provides a negative pressure calculus removing sheath for percutaneous nephrolithotomy. The negative pressure calculus removing sheath for percutaneous nephrolithotomy comprises an outer sheath body, an inner sheath body, inner sheath side holes and a vacuum extractor, wherein the inner sheath body is sleeved with the outer sheath body, the inner sheath body is parallel to the outer sheath body in the longitudinal direction and is fixed to one side of the outer sheath body, one end of the inner sheath body is flush with one end of the outer sheath body, the two inner sheath side holes are formed near the end of the inner sheath body, and the other end of the inner sheath body stretches out of the outer sheath body to be communicated with the vacuum extractor. The negative pressure calculus removing sheath for percutaneous nephrolithotomy has the advantages that the sheath is convenient to operate during an operation, and the broken calculus removing efficiency can be effectively improved during percutaneous nephrolithotomy; by the adoption of the negative pressure calculus removing sheath for percutaneous nephrolithotomy, the pressure inside the kidney pelvis can be reduced, the possibility that the infection is aggravated during the operation is lowered, and complications caused by the operation are reduced.
Description
Technical field
This utility model relates to the medical apparatus and instruments in a kind of Urology Surgery percutaneous lithotripsy of kidney, the clear stone sheath of especially a kind of PCN negative pressure.
Background technology
Urinary system calculus is the commonly encountered diseases of urinary system, calculus is found in any position of kidney, bladder, ureter and urethra, but taking kidney and ureteral calculus as common, percutaneous nephrolithotomy is the common means of processing urinary calculi, completes every year PCN amount for surgical all very large.The outstanding advantage of percutaneous nephrolithotomy shows the aspects such as Wicresoft, painless, rubble is thorough, operating time is short.Using endoscopic system operation is the trend of the advanced treatment means in the world.This technology the most intuitively advantage is exactly invasive, the treatment means of " driving machete " as compared with the past, and the suffered wound of patient is less, recover faster.PCN operation is at present through improvement many times, and the improvement of for example position, adopts ventricumbent position, recumbent position, dorsal position, lateral position and section stone to face upward the various body positions modes such as recumbent position and carry out PCN operation.
In operation often in conjunction with negative pressure, negative pressure suction device is connected with PCN four-way side opening, carry out stone clearly according to surgery situation, can obviously improve clear stone efficiency, but because the passage in PCN apparatus mirror body is very thin, existing operation technique apparatus in passage, carry out again vacuum suction, clear stone is had a certain impact, easily residual calculus, and in rubble process,, because renal pelvis internal pressure is too high, easily retrograde infection causes pyemia, septicemia etc.
Summary of the invention
This utility model patent aims to provide the clear stone sheath of a kind of PCN negative pressure, comprising: epitheca, interior sheath, interior sheath side opening, vacuum extractor, and described epitheca inner sleeve has interior sheath; Longitudinal and the epitheca parallel longitudinal of described interior sheath, is fixed on a side in epitheca; The termination of interior sheath one end flushes with the termination of epitheca, has a two interior sheath side opening near this termination; The other end of interior sheath extends epitheca, is communicated with vacuum extractor.
Described vacuum extractor comprises negative pressure connection tube and negative pressure regulating valve; Described negative pressure regulating valve is installed on negative pressure connection tube; Described negative pressure connection tube one end is communicated with interior sheath, and the other end is communicated with negative pressure suction device.
The diameter of described epitheca is 7-12mm, and length is 18-25cm.
The diameter of described interior sheath is 3-5mm, and the diameter of interior sheath side opening is 0.8-1.2mm.
Described epitheca and interior sheath are made up of polypropylene material.
This utility model patent is easy to operate in operation, can effectively improve the efficiency of the clear stone of PCN operation process medium stone.
In routine operation in conjunction with negative pressure, negative pressure suction device is connected with PCN side opening, carry out stone clearly according to surgery situation, can obviously improve clear stone efficiency, but because the passage in PCN apparatus mirror body is very thin, existing operation technique apparatus in passage, carries out vacuum suction again, and clear stone is had a certain impact.The clear stone sheath of this utility model PCN negative pressure, without above-mentioned drawback, can be adjusted at any time negative pressure regulating valve according to surgery situation and regulate vacuum suction pressure size.PCN can pass in and out PCN passage freely through this sheath in addition, removes larger and less calculus simultaneously, directly sucking-off of less explanation, and larger calculus can be drawn through this sheath, greatly improves clear stone efficiency.
The clear stone sheath of PCN negative pressure that this utility model provides can reduce operation process renal pelvis internal pressure, reduces in operation process and infects the possibility increasing the weight of, and reduces the complication of operation.Originally needed calculus that the II phase processes to merge the patient of pyonephrosis, under the help of this sheath, the I phase just can be processed calculus, reduced infection complication, shortened hospital stays of patient, reduced patient's hospitalization cost.
Brief description of the drawings
Fig. 1 is the structural representation of the clear stone sheath of PCN negative pressure that provides of this utility model
Fig. 2 is the interior sheath of the clear stone sheath of PCN negative pressure that provides of this utility model and the cutaway view of epitheca
Wherein, 1-epitheca, sheath, the interior sheath side opening of 3-, 4-vacuum extractor in 2-; 41-negative pressure connection tube, 42 negative pressure regulating valves.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of embodiment of the present invention is described:
As depicted in figs. 1 and 2, the clear stone sheath of PCN negative pressure comprises epitheca 1, interior sheath 2, interior sheath side opening 3, vacuum extractor 4, and described epitheca 1 inner sleeve has interior sheath 2; Longitudinal and epitheca 1 parallel longitudinal of described interior sheath 2, is fixed on a side in epitheca 1; The termination of interior sheath 2 one end flushes with the termination of epitheca 1, has a two interior sheath side opening 3 near this termination; The other end of interior sheath 2 extends epitheca 1, is communicated with vacuum extractor 4.
Described vacuum extractor 4 comprises negative pressure connection tube 41 and negative pressure regulating valve 42; Described negative pressure regulating valve 42 is installed on negative pressure connection tube 41; Described negative pressure connection tube 41 one end are communicated with interior sheath 2, and the other end is communicated with negative pressure suction device.
The diameter of described epitheca 1 is 7-12mm, and length is 18-25cm.
The diameter of described interior sheath 2 is 3-5mm, and the diameter of interior sheath side opening 3 is 0.8-1.2mm.
Described epitheca 1 and interior sheath 2 are made up of polypropylene material.
This utility model is in the time carrying out PCN operation, can freely pass in and out PCN passage through the clear stone sheath of this PCN negative pressure, remove larger and less calculus, directly sucking-off of less explanation simultaneously, larger calculus can be drawn through this sheath, greatly improves clear stone efficiency.The clear stone sheath of PCN negative pressure can reduce operation process renal pelvis internal pressure, reduces in operation process and infects the possibility increasing the weight of, and reduces the complication of operation.Originally needed calculus that the II phase processes to merge the patient of pyonephrosis, under the help of this sheath, the I phase just can be processed calculus, reduced infection complication, shortened hospital stays of patient, reduced patient's hospitalization cost.
