Description

Human body silica gel seal wire external member

Technical field

The utility model belongs to medical auxiliary apparatus technical field, and in particular to human body silica gel seal wire external member.

Background technique

Double J pipe (pigtail catheter), this project this external member combination is conducive under laparoscope or open ureter hand Art, when ureteralithotomy, place double J pipe, which does not allow to easily cause ureter perforation and damage when placing, and use and more may be used It leans on and conveniently, and by manufacture ureter rack tube, substitution clinic with histocompatbility best soft human body silicone tube The not so good silica gel support pipe of commonly used harder and histocompatbility, mitigating patient's indwelling tube of double-J pain is that this project exists The innovation in urological surgery field.

Existing double J pipe is made of two parts, double J pipe and seal wire, and seal wire is 2-3 times longer than double J pipe, when operation is placed very It is inconvenient.Double J pipe is many kinds of, has the other end open at one end closed, also has both ends to be all closed formula, in operation, guiding wire It is supportted directly from the insertion of the side opening of double J pipe by double J pipe, double J pipe enters corresponding position along guiding wire, extracts guiding wire, double J pipe out It resiles.Have a kind of closed at both ends and be made into the seal wire set being equal with guidewire length, both ends are respectively bladder end and kidney Broad-mouthed receptacle for holding liquid end, and port closed, matched seal wire is flexible wire, and each section of hardness of entire wire is equal It is identical, curved upper section ureter is not easy double J pipe being put into renal plevis through ureter, extends the surgical medical time, and And this external member is harder due to combining, and the damage and perforation of ureter are be easy to cause in art, it is especially uncomfortable curved defeated The problem of placing ureteral catheter in urinary catheter operation, thus it is proposed that human body silica gel seal wire external member.

Utility model content

It is mentioned above in the background art existing to solve the purpose of this utility model is to provide human body silica gel seal wire external member Some double J pipes are many kinds of, have the other end open at one end closed, also have both ends to be all closed formula, and in operation, guiding wire is from double The side opening insertion of J pipe supports double J pipe directly, and double J pipe enters corresponding position along guiding wire, extracts guiding wire out, and double J pipe restores Original shape.Having a kind of closed at both ends and is made into the seal wire set being equal with guidewire length, both ends are respectively bladder end and renal plevis end, And port closed, matched seal wire is flexible wire, and each section of hardness of entire wire is all the same, It is highly detrimental to the accurate importing of seal wire, extends the surgical medical time, also, this external member is harder due to combining, art In be easy to cause the damage and perforation of ureter, place asking for ureteral catheter in especially uncomfortable curved operation on ureter Topic.

To achieve the above object, the utility model provides the following technical solutions: human body silica gel seal wire external member, including seal wire master Body and the human body silica gel double J pipe main body being used cooperatively with the guidewire body, the guidewire body by flexible hard end with And soft end composition；The end of the end held firmly and the soft end is linked together；The human body silica gel double J pipe main body includes position In middle part urine output pipe portion and be located at the bladder inlet and renal plevis inlet at urine output pipe portion both ends；The bladder One end of inlet and the renal plevis inlet is connected to connection with the both ends of the urine output pipe portion respectively, the bladder inlet and The other end of the renal plevis inlet is respectively the pointed closed end of semicircle and open end, and bladder inlet is that closed semicircle is pointed End, renal plevis inlet are open pointed end；Run through in the human body silica gel double J pipe main body and offers multiple side openings；It is described to lead Silk main body may pass through the side opening.

Preferably, the length held firmly is equal to the length of the human body silica gel double J pipe main body, a length of 5 lis of the soft end Rice, and for the hard end, one end hardness closer to the soft end is lower.

Preferably, 5 centimetres of the open end of renal plevis inlet end is stretched out at the soft end.

Compared with prior art, the utility model has the beneficial effects that guidewire body is by flexible hard end and soft End composition, the optional length held firmly and human body silica gel double J pipe main body are isometric, and bladder inlet and the renal plevis inlet is another One end is respectively closed end and open end, and the open end of renal plevis inlet end is stretched out at soft end, and hard end is conducive to seal wire It is inserted into human body silica gel double J pipe main body, is conducive to be put into double J pipe through ureter through ureter notch, soft end is played guiding function and matched It closes open end to be conducive to human body silica gel double J pipe main body being put into renal plevis through ureter, hard end is conducive to human body silica gel double J pipe master Body is inserted into ureter lumen, and soft end cooperation open end is conducive to human body silica gel double J pipe main body being put into ureter upper end and renal plevis, It is more convenient to use reliable, reduce the incidence of injury of ureter and perforation.
