Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of percutaneous kidney dilator for operation tool.
Background technology
At present, through skin puncture kidney and between skin and kidney, set up service aisle, take out renal calculus then, be referred to as percutaneous nephrolithotomy with aponeurosis of investment.The operation of percutaneous kidney more and more has been applied to handle various kidneys and ureter epimere disease.In the operation of percutaneous kidney, the foundation of service aisle is crucial between skin and the kidney, when using traditional dilator to carry out the passage expansion, need recycle X line location or the degree of depth when measuring dilator and enter with gage, during operating cost, and be prone to the expansion degree of depth inadequately or dark excessively.When kidney mirror or ureteroscope undergo surgery by the work sheath, usually need in sheath, keep somewhere a safety guide wire and play the safe guidance effect, but in art because the frequent access way of continuous variation and endoscope of work sheath angle, safety guide wire very easily skids off, even cause sheath to be deviate from, thereby cause operative failure.
The utility model content
The purpose of this utility model is to provide a kind of safe percutaneous kidney dilator for operation tool, the eely problem of safety guide wire in the degree of depth of repeated measurement when setting up expansion to solve percutaneous kidney passage, location dilator and the art.
Percutaneous kidney dilator for operation tool provided by the utility model comprises convergent divergent channel (Fig. 2,3) and aponeurosis of investment (Fig. 1), and described expansion utensil can be formed external member and use, and every cover expansion external member comprises convergent divergent channel and an aponeurosis of investment of different size from small to large.
Percutaneous kidney operation expansion external member provided by the utility model, its aponeurosis of investment is the cylindric pipeline (1) of even hollow, outer wall is marked with scale (2); The aponeurosis of investment diameter is from 10Fr to 26Fr, and preferred 14Fr is to 24Fr; Length is 10-20cm, preferred 15cm.There is a safety guide wire passage (3) parallel with the sheath major axis described aponeurosis of investment wall inboard, this channel diameter 0.5-1.5mm, and preferred 1.0-1.2mm can insert safety guide wire through this passage.
Percutaneous kidney operation expansion external member provided by the utility model, its convergent divergent channel front end is tip, and main part is for evenly cylindric.Diameter from 6Fr to 26Fr, preferred 8Fr-24Fr.Convergent divergent channel length is 20-25cm, preferred 22cm.Convergent divergent channel is hollow design, and head end has front end circular hole (4,6), and the afterbody opening can be inserted seal wire via hollow channel.The convergent divergent channel outer wall is marked with scale (5,7), but direct observation enters the degree of depth during expansion.There are two with the convergent divergent channel of aponeurosis of investment same size, wherein one is the convergent divergent channel (Fig. 3) of band groove, its main part has a groove (8) parallel with major axis, and groove (8) diameter is consistent with inboard safety guide wire passage (3) size of aponeurosis of investment wall, so that this convergent divergent channel can insert aponeurosis of investment.
When service aisle was set up in percutaneous kidney operation, at first the convergent divergent channel from the size minimum began expansion, when being expanded to full-size, the convergent divergent channel of aponeurosis of investment and coupling was put, and inserted service aisle together.Scale on the convergent divergent channel can intuitively reflect the expansion degree of depth, need not repeated measurement or location.During expansion if aponeurosis of investment reach renal pelvis or renal calices, urine from seal wire designated lane hole or the dilator groove overflow, the effect of the security monitoring degree of depth is arranged; If carry out the B ultrasonic location, then can in hole or groove, put into the relation of ultrasonoscopy pin with clear and definite dilator and kidney.
The beneficial effects of the utility model are, compare with traditional percutaneous nephrectasis device, and the location is more accurate in the process of expansion, and it is more convenient to operate, safer in the operation process.In the operation implementation process, because fixed safety guide wire designated lane is arranged on the aponeurosis of investment wall, moving of mirror body do not influence safety guide wire when therefore operating, and need not to adjust repeatedly the seal wire angle and the degree of depth, and seal wire can be because of shank operation slippage yet.This utility model has improved the efficient and the safety of percutaneous kidney operation, and is therefore significant, has higher popularization and application values.
