Sleeved double J pipe pipe extractor

Technical field

This utility model relates to technical field of medical instruments, especially a kind of double J pipe pipe extractor.

Background technology

Double J pipe is because having good support and interior drainage, be widely applied in Urology Surgery every field, as Nephrolithotomy mirror (PCN), ureter rubble, ureteral obstruction, all kinds of openings of ureter, endoscope-assistant surgery etc., compared with support arm drainage tube, double J pipe have drain reliable, reduce infection rate, be beneficial to patient and recover as early as possible, improve the quality of living and facilitate economic dispatch superiority.The double J pipe of application is that polyurethane (full name polyurethanes) material is made clinically at present, its biocompatibility is better, but nonabsorable, therefore need the needs according to the different state of an illness, double J pipe after indwelling reasonable time, all needs to take out or change in ureter.

At present, be to take out with foreign body forceps per urethra cystoscope for take out the most popular method of double J pipe from ureter.Tradition foreign body forceps comprises fixed handle, flexible handle, claw beam, pull bar and clamp, controls the folding of clamp by flexible handle; Tradition foreign body forceps is in double J pipe tube drawing process of clinical application, under the cooperation of urethrocystoscope, directly clamp is clipped on double J pipe, then double J pipe being pulled out along urethra, can there is more problem in such operation: 1) in the time that double J pipe tube wall adheres to calculus or Mycoderma, not only in the process pulling, between foreign body forceps and double J pipe, easily there is de-pipe phenomenon, but also easily cause that calculus is cracked is scattered, and making calculus residue indwelling intravesical, attached duct ligation stone residue also can cause damage to mucous membrane of urethra; 2) foreign body forceps is generally all-metal material, and damage can be caused to mucous membrane of urinary bladder in operating side, while exiting operating apparatus, also can cause mechanical damage to mucous membrane of urethra, bring very big misery to patient, especially male patient, is obviously longer than female patient because of its urethral length, and misery is larger.

Utility model content

This utility model technical issues that need to address are to provide a kind of double J pipe pipe extractor, and the problem existing in the clinical practice of double J pipe tube drawing to overcome traditional foreign body forceps reduces de-pipe incidence rate in operating process, reduces the damage to bladder and mucous membrane of urethra.

For solving the problems of the technologies described above, technical solution adopted in the utility model is:

Sleeved double J pipe pipe extractor, comprise tube drawing line, described tube drawing line be placed in sleeve pipe and in one end of sleeve pipe, form can lasso trick at the sealing ring set of double J pipe end, the other end of described sleeve pipe is provided with umbrella sleeve cap, on described sleeve cap, be provided with nut and bolt for tube drawing line being pressed in sleeve pipe and cooperatively interacting, described bolt shaft is to being provided with the through hole passing for tube drawing line, and the thread segment of bolt bottom is provided with the slot segmentation that runs through vertically thread segment.

Further improvement of the utility model is: the umbrella groove that the setting of described nut inner chamber matches with sleeve cap, described bolt lower end arranges the conical screw head matching with sleeve cap.

Owing to having adopted technique scheme, the obtained technological progress of this utility model is:

Sleeved double J pipe pipe extractor of the present utility model, overcome the problem that traditional foreign body forceps exists in the clinical practice of double J pipe tube drawing, reduce de-pipe incidence rate in operating process, reduce the damage to bladder and mucous membrane of urethra, apparatus structure is simple, easy operating, operating time is short, safe, reduces patient's misery, improve doctor's work efficiency, be convenient to clinical application.

Sleeved double J pipe pipe extractor, effectively reduces the incidence rate that takes off pipe in operating process, and especially double J pipe tube wall adheres to the case of calculus or Mycoderma; Be applied to all calculus of the pipe case of adhering to, can avoid that calculus is cracked is scattered, effectively reduce that calculus residue is detained and attached duct ligation stone residue damage mucous membrane of urethra; Operating side sealing, pliable and tough, can reduce the damage to mucous membrane of urinary bladder; After fixing double J pipe, still have good pliability and mobility, reduced the mechanical damage to mucous membrane of urethra while exiting operating apparatus; Can singlely operate, good operability, is convenient to grasp.Apply this pipe extractor simultaneously and also can reduce running cost, reduce Extubation in Patients expense.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further details.

Structure of the present utility model as shown in Figure 1, 2, mainly comprises tube drawing line 1, sleeve pipe 2, nut 3 and bolt 4.

Tube drawing line 1 is placed in sleeve pipe 2 and in one end of sleeve pipe 2 and forms and seal ring set 1-1, ring set 1-1 can lasso trick in double J pipe end, ring set 1-1 can be that one end of tube drawing line 1 ties up on tube drawing line 1 body and forms, also can be two ends rear formation side by side of tube drawing line 1, the preferably two ends rear ring set 1-1 forming side by side, the material of tube drawing line 1 is the hard rope with certain toughness and hot strength.

The material of sleeve pipe 2 is the stereoplasm tube with certain toughness and hot strength, one end of sleeve pipe 2 is the external part of ring set 1-1, the other end has umbrella sleeve cap 2, the nut 3 and the bolt 4 that match are set on sleeve cap 2, nut 3 lower ends arrange the hole that sleeve pipe 2 can pass, bolt 4 is axially provided with the through hole passing for tube drawing line 1, the thread segment middle part of bolt 4 bottoms arranges slot segmentation 4-1, slot segmentation 4-1 runs through thread segment vertically, thread segment is divided into two parts, tube drawing line 1 passes from bolt 4 by slot segmentation 4-1 and through hole, bolt 4 adopts plastic material, plastic material can produce deformation in the time of extruding, in the time that bolt 4 is tightened in nut 3, slot segmentation 4-1 gap smaller, two parts thread segment is just extruded and is close together, like this by nut 3, between bolt 4 and sleeve cap 2-1, coordinate, tube drawing line 1 can be pressed in sleeve pipe 2, now ring set 1-1 can change direction with the rotation of bolt 4 along with nut 3.

The umbrella groove 3-1 that nut 3 inner chamber settings match with sleeve cap 2-1, bolt 4 lower ends arrange the conical screw head 4-2 matching with sleeve cap 2-1.Tube drawing line 1 can be fixed in sleeve pipe 2, as shown in Figure 3,4 better like this.

Using method of the present utility model is: sleeved rope J pipe pipe extractor is installed, set the size of ring set 1-1, and by bolt 3, nut 4, tube drawing line 1 is fixed in sleeve pipe 2.For the patient that need to carry out double J pipe tube drawing, first, under urethrocystoscope, position or the surface of specifying double J pipe have or not calculus to exist; Sleeved double J pipe pipe extractor is inserted via urethrocystoscope mirror sheath, under the assistance of urethrocystoscope, ring set 1-1 is enclosed within to one end of double J pipe, can adjust by rotating screw cap 3 and bolt 4 direction of ring set 1-1, entangle after double J pipe until ring set 1-1, will between bolt 3, nut 4, unscrew drawing pipeline 1, ring set 1-1 is tightly enclosed within on double J pipe, then will between bolt 3, nut 4, screws; Double J pipe is taken out, and in the process of taking-up double J pipe, sleeve pipe 2 enters in the mirror sheath of urethrocystoscope, and double J pipe is extracted followed by urethrocystoscope, avoids the damage to bladder and mucous membrane of urethra.
