Description
Technical field
This utility model belongs to technical field of medical instruments, especially a kind of Wicresoft expansion two-chamber ureter guiding sheath external member.
Background technology
Wicresoft's expansion guiding sheath external member is mainly used in ureter, bladder, kidney clinically gets calculus, and carrying out related surgical treatment, to set up operation path used, imports endoscope, laser fiber, calculus removing instrument or operation cable etc. by passage.Operating procedure: under medical image, observe in ureter, bladder, kidney and have calculus, per urethra collar extension inserts a zebra guide wire, zebra guide wire guide underlying enter Wicresoft's expansion guiding sheath external member to getting Plumbum preparatium position, extract zebra guide wire, in Wicresoft's expansion guiding sheath external member, import Flexible ureteroscope, endoscope, laser fiber, calculus removing instrument or operation cable etc. to ureter, bladder or renal pelvis carry out related surgical operation; In operation process, doctor inserts endoscope, laser fiber, calculus removing instrument through sheath tube passage, and must can flow out external through sheath tube passage with liquid with rubble while of len by marginal not water in the process of laser lithotripsy, remaining excretes through human urethra.But Renal pelvic pressure power can be caused in the injecting process to exceed renal pelvis safe pressure, increase operation risk.Wicresoft of the prior art expansion guiding sheath external member is all generally single chamber, is difficult to by soft lens sheath monitoring renal pelvis pressure in the process of rubble.After rubble, stone flows out external through liquid Wicresoft of the prior art expansion guiding sheath external member is by natural pressure, and velocity ratio comparatively slowly and discharge not thorough.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Wicresoft expansion two-chamber ureter guiding sheath external member, can solve the deficiencies in the prior art, be convenient to the monitoring to Renal pelvic pressure power and adjustment, accelerate the discharge for rubble.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of Wicresoft expansion two-chamber ureter guiding sheath external member, comprise sheath pipe body, the first separate cavity and the second cavity is provided with in sheath pipe body, sheath pipe body top is connected with sheath pipe joint, the side of sheath pipe body is connected with stress test conduit, stress test conduit is connected with the first cavity, sheath pipe joint is connected with the second cavity, fixedly sleeve is connected with above sheath pipe joint, the sidewall of sleeve is provided with negative pressure absorbing pipe, the top card of sleeve is connected to upper cover, silica gel valve is provided with between upper cover and sleeve, convergent divergent channel body is optionally plugged in the second cavity, convergent divergent channel body top is fixed with fixation clamp, fixation clamp is clamped in the outside of upper cover.
As preferably, the end of described convergent divergent channel body is provided with wedge-shaped part.
As preferably, the material of described wedge-shaped part is medical silica-gel.
As preferably, described silica gel valve comprises silicagel pad, and the center of silicagel pad is provided with manhole.
As preferably, described sheath pipe body, the first cavity, the second cavity and sleeve adopt transparent Teflon material to make.
The beneficial effect adopting technique scheme to bring is: sheath pipe shaft design is become two-chamber by this utility model, import sheath pipe box part and adopt transparent material, ureteral pathological changes situation conveniently can be observed, to clinical operation with very large help by camera lens when inserting apparatus.First cavity carries out related surgical operation for importing Flexible ureteroscope, endoscope, laser fiber, calculus removing instrument or operation cable etc. to ureter, bladder or renal pelvis; Second cavity is used for Bonding pressure sensor, connects monitor, can read in the renal pelvis pressure in operation process accurately, guarantee that in operation process, renal pelvis pressure is within safe pressure scope by pressure transducer.On Wicresoft's expansion guiding original basis of sheath external member, increase a negative pressure system getting stone place, can effectively regulate Renal pelvic pressure power by negative pressure system, the rubble rate of outflow can be regulated by the sorption channel of negative pressure system and the remaining rubble of thorough sucking-off, reduce operating time.The end of convergent divergent channel body is provided with wedge-shaped part, and the material of wedge-shaped part is medical silica-gel, does not damage ureter Inner wall and sphincter when making to insert ureter and urethra, and effectively shortens the time of putting pipe operation
