Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, in the embodiment of the present invention, a novel comfortable ureteral stent which is easy to take out without operation includes a stent body 1 and a drainage body 9, the stent body 1 is made of soft polyurethane or silica gel material to prevent the stent body 1 from wrinkling when placed, one end of the stent body 1 is provided with a J-shaped tube 2, the other end of the stent body 1 is provided with a bell 3, the connecting portion between the bell 3 and the stent body 1 is connected with a silk thread 8, and the other end of the silk thread 8 is connected with the drainage body 9.
In this embodiment, the ureteral stent body 1 is made of relatively soft polyurethane or silica gel, so that the double J-shaped tube is not wrinkled when placed through the guide wire, and the placement is difficult. Meanwhile, the body of the bracket body 1 is soft, the tissue compatibility is good, the discomfort of lumbago, distending pain of waist and the like of a patient after the ureteral bracket is placed can be obviously relieved, and in addition, the round hole 4 is further formed in the outer surface of the bracket body 1, so that the drainage dredging effect is improved.
In this embodiment, J type pipe 2 is the polyurethane material of hardness 95, J type pipe 2's hardness is greater than the hardness of support body 1 and bellmouth 3 in proper order, J type pipe 2 is harder relatively, in order to guarantee that ureteral stent can pass through ureteral bladder entrance smoothly via the guide wire propelling movement, after backing away the propelling movement guide wire, in order to guarantee the crookedness of J type pipe 2 in the renal pelvis, make it finally can block in the renal pelvis end, make support body 1 be difficult to shift, prevent because patient's activity and gravity factor, support body 1 upper end moves down and drops to in the bladder.
The effect of support body 1 lies in playing the support and the drainage of ureter, so must one section place in the renal pelvis, guarantee not to shift, drop, another section must be in the bladder, in order to guarantee that the drainage is unobstructed, guarantee simultaneously that support body 1 advances through the harder end of J type pipe 2, it is easier to pass through vesicoureteral opening part when upwards placing from the bladder, bellmouth 3 card is in the bladder, the bellmouth 3 of putting into the bladder is extremely soft silica gel material, prevent that vesicoureteral reflux wriggling or bladder shrink from causing support body 1 lower extreme upwards to retract the removal, make it be difficult for moving up to in the ureter. The bell mouth 3 at the lowest end is very soft, and the contact comfort of the bell mouth is further improved while the existing bell mouth-shaped model is limited; meanwhile, the hydrophilic coating is arranged on the whole outer surface of the ureteral stent, and even if the bell mouth 3 contacts the bladder wall, obvious phenomena of frequent micturition, urgent micturition, pain in micturition and hematurition can not be generated.
The J-shaped pipe 2, the bracket body 1 and the bell mouth 3 can be formed by welding or can be integrally formed. In some embodiments of the utility model, be provided with first magnetic metal ring 5 between support body 1 and the J type pipe 2, first magnetic metal ring 5 respectively with support body 1 and J type pipe 2 looks adaptation, be provided with second magnetic metal ring 6 above horn mouth 3, first magnetic metal ring is positive negative magnet relation with second magnetic metal ring, forms the internal magnetic field of body, can reduce the formation of pipe wall calculus, reduces the discomfort after patient's the placing. In this embodiment, the discharging body 9 is a small ball with holes, so that the whole body is smooth and easy to discharge out of the body, and no obvious foreign body sensation is generated in the body.
The small ball with the hole and the silk thread 8 are used for being placed into the bladder, the small ball with the hole can pass through 038/150 loach guide wires, the length of the silk thread 8 exceeds the length of the male urethra, if the discharger 9 and the silk thread 8 are discharged out of the body too early, the silk thread 8 is fixed out of the body by using adhesive tapes, and the ureter stent in the body is pulled out automatically at a proper time; and the discharging body 9 is discharged through the urine of the patient, and the whole ureteral stent can be taken out from the body of the patient through the silk thread 8, so that the secondary bladder operation is avoided, and the pain of the patient is relieved.
In the embodiment, the discharger 9 is a pellet provided with a through hole for passing through a loach or zebra guide wire, and the silk thread 8 passes through the through hole to fix the pellet; the through holes are provided for facilitating the thread 8 to pass through and bind the pellets, and for enabling the discharger 9 to pass through the guide wire along with the ureteral stent to be pushed in during the operation process, and placing the ureteral stent and the pellets with holes into the ureter and the bladder respectively.
In this embodiment, the function of the pellet is to facilitate the doctor to put the pellet and the silk thread into the bladder through the guide wire, and the pellet can be discharged out of the body along with urine due to the gravity relationship. The patient can pull out the single J tube out of the body through the small balls and the silk threads discharged out of the body, so that the pain of taking out the double J tubes in a secondary cystoscope operation is avoided, and the economic burden of the patient is relieved.
In some embodiments of the present invention, the second magnetic metal ring 6 disposed on one side of the stent body 1 close to the bell mouth 3 can be used as an indication mark for placing at the opening of the uretero bladder.
Can distinguish the renal pelvis and the bladder department that J type pipe 2 and bell mouth 3 correspond respectively through index mark 6, prevent to use instead, increase the convenience of using, make things convenient for doctor's operation.
The utility model discloses a theory of operation is:
in the installation process, the J-shaped pipe 2 is placed at the renal pelvis of a patient, and then the bell mouth 3 is placed at the bladder of the patient and clamped on the bladder;
in the using process, the discharging body 9 is discharged through the urine of a patient, namely, the whole ureteral stent can be taken out from the body of the patient through the silk thread 8, so that the secondary bladder operation is avoided, and the pain of the patient is relieved;
in the protective measure, through adopting this degressive hardness design and soft and hard section combination in proper order, the harder assurance J type head shape of renal pelvis end is difficult for droing, the ureter support body is softer, adopt this degressive hardness design in proper order, the terminal softer material of ureter body links to each other with the extremely soft horn type silica gel material of putting into the bladder, the material welding and the fixed approach of two kinds of different hardnesses, guarantee the novel ureter support of comfortable type that the operation of exempting from being convenient for take out and can place smoothly through the seal wire and can not corrugate the circumstances, guarantee the compliance in ureter support implantation, hydrophilic coating guarantees the compatibility of tissue simultaneously, can alleviate the uncomfortable sense after patient ureter support implantation to a certain extent. The first magnetic metal lantern ring and the second magnetic metal lantern ring are in a positive and negative magnet relationship, and an internal magnetic field of a formed body can reduce the formation of calculus on the pipe wall and reduce discomfort of a patient after the patient is placed.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
