Abstract
The utility model discloses a degradable hydrophilic pigtail conduit, comprising a pipe body, wherein the pipe body is a double-J conduit or a single-J conduit; one end or two ends of the pipe body are arranged in the shape of a pigtail; and the pipe body is a conduit made of a hydrophilic degradable material. The conduct is made of a bioabsorbable aliphatic polyester material, so that the conduit can be decomposed automatically or can be gradually decomposed into micromolecules under the action of microorganisms, enzymes and the like, and then discharged from the body in virtue of metabolism. Therefore, a secondary pull-out surgery of the conduct is successfully avoided, pains of patients are relieved, and meanwhile, the surgery security is enhanced.
Description
Technical field
This utility model relates to a kind of conduit, particularly a kind of degradable hydrophilic type pigtail conduit.
Background technology
The pigtail conduit curls because of two ends, and every end is similar to pigtail and gains the name.In the Urology Surgery operation, use very extensive; Be applicable to that in the therapeutic processes such as expansion of last urinary tract operation such as renal calculus, ureteral calculus, hydronephrosis, renal transplantation, kidney and ureter benign tumor and lithotrite rubble, stricture of ureter, its can play drainage of urine after implanting ureter, prevent the important function that stricture of ureter and adhesion are stopped up.Mostly the pigtail conduit of clinical practice at present is that silicone rubber or polyurethane high molecule material process.But because these materials all can not degraded and absorbed in human body, the self-defect that existing pigtail catheter product all exists some to overcome in application facet:
(1) must promptly pull out through the invasive operation through cystoscope; Though this type cystoscope operation is not really major operation, patient understands agonizing, the even more serious damage that can cause degree varies when being tube drawing to urinary tract tissue; Make it take place to infect and edema, often need emergency treatment.
(2) because a variety of causes; Many patients can forget tube drawing or postpone tube drawing, and nondegradable support tube is kept somewhere formation urinary stone in the body for a long time, can't be when intracavity is pulled out; Have to take open surgery to be taken out, this has seriously increased patient's misery and financial burden undoubtedly.
(3) nondegradable ureter rack tube also usually causes some complication; Prolongation along with the support tube indwelling time; These materials begin to influence urothelium and urine composition; Cause forming coating, bacterial biof iotalm and causing infection around the support tube, common complication has: waist abdomen pain, frequent micturition, urgent micturition, dysurea, hematuria and infection etc.This all is because nondegradable conduit causes due to the foreign body reaction for a long time in vivo.
The utility model content
The utility model purpose: this utility model is in order to solve the deficiency of prior art, provide a kind of easy and simple to handle, increase work efficiency, safe and reliable degradable hydrophilic type pigtail conduit.
The technical scheme that this utility model adopts: a kind of degradable hydrophilic type pigtail conduit, comprise body, said body is two J conduits or single J conduit, said body one or both ends are set as the pigtail shape, the conduit that said body is processed for the hydrophilic degradable material.
As optimization, said body can decompose voluntarily.The manufacturing materials of conduit adopts biology can absorb the aliphatic poly ester material; This material contains hydrolyzable chemical bond usually, and like ester bond etc., so it can decompose voluntarily; Also can progressively be decomposed into micromolecule, discharge living external again via metabolism by effects such as microorganism, enzymes.Its structure of synthetic absorbable material, kenel, engineering properties and degradation time can both design and regulate and control in advance.Aliphatic polyesters such as polylactic acid have good biocompatibility, Biodegradable, have become the most potential material in the biodegradation field of medical materials at present.Has aseptic avirulence; Material have enough toughness and degradation time adjustable, material is prone to machine-shaping.Can satisfy the needs of various long-term or short-term implants, many forms arranged by U.S. food and FAD institute (FDA) approval.
As optimization, said body is provided with graduation mark.
As optimization, said body is provided with aperture.
As optimization, said body is arranged to random color.
Beneficial effect: safe and reliable.Successfully solved owing to a variety of causes, the patient forgets tube drawing or postpones tube drawing and in the patient body, form urinary stone, to such an extent as to the removal of having to undergo surgery.Increase patient's misery and financial burden.Increase work efficiency.The pigtail conduit that degradable absorbs gets into after the human body, and liquid etc. need not guarded and get to the automatic degraded and absorbed of meeting for a long time, do not worry follow-up complication.

Fig. 2 is the degradable hydrophilic type pigtail guide-tube structure sketch map of single J conduit for body.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment this utility model is described further:
Embodiment 1
As shown in Figure 1, a kind of degradable hydrophilic type pigtail conduit comprises body 1; Said body 1 two ends are pigtail shape 2, and said body 1 is processed by the absorbable aliphatic poly ester material of biology, and said body 1 is provided with graduation mark 3; Said body 1 is provided with aperture 4, and body 1 is white in color.
Embodiment 2
As shown in Figure 2, a kind of degradable hydrophilic type pigtail conduit comprises body 1; Said body 1 one ends are pigtail shape 2, and said body 1 is processed by the absorbable aliphatic poly ester material of biology, and said body 1 is provided with graduation mark 3; Said body 1 is provided with aperture 4, and it is green that body 1 is.
Claims (4)
