Problems solved by technology

Clinically, there is generally no special floating line for anal fistula irrigation catheter with irrigation function. Silk thread (sometimes multiple) or simple elastic is often used during operation, and the purpose of drainage is achieved through silk thread or elastic itself drainage or rotation. The drainage effect of this method is not good, and it will increase the discomfort of the patient

Embodiment 1

[0026] Such as figure 1 As shown, the anal fistula flushing floating line disclosed in this embodiment includes a flushing conduit 1, the front end of which is closed, and a water inlet 3 is provided on the rear side wall of the flushing conduit 1, and the water outlet 2 of the flushing conduit 1 is located in the flushing conduit 1 In the middle, the front end and the rear end of the flushing conduit 1 are detachably connected. Further, the inner diameter of the rear opening 5 of the irrigation catheter 1 is greater than or equal to the outer diameter of the front end of the irrigation catheter 1 , and the front end of the irrigation catheter 1 is clamped with the rear end.

[0027] After the present invention is placed in the operation, the front end of the irrigation catheter 1 can be embedded in the rear opening 5 . In order to make the connection between the front end and the rear end of the flushing conduit 1 more stable, the front end of the flushing conduit 1 is provi...

Embodiment 2

[0032] The difference between this embodiment and embodiment 1 is: as image 3 As shown, the entire flushing conduit 1 is hollow, and an inner tube 10 is arranged in the flushing conduit 1 , one end of the inner tube 10 communicates with the water outlet 2 , and the other end of the inner tube 10 communicates with the water inlet 3 .

[0033] When the diameter of the flushing conduit 1 is equal to three times the diameters of the needles of No. 5, No. 7 and No. 9 syringes, the inner diameter of the inner tube 10 is respectively equal to the diameters of the needles of No. 5, No. 7 and No. 9 syringes.

[0034] The invention is easy to operate, simple and practical, has the functions of flushing and drainage, can flush the lumen, has sufficient drainage, reduces the pain of changing dressings for patients, shortens the course of disease, and improves the cure rate of anal fistula.

Abstract

The invention relates to an anal fistula flushing floating thread. The anal fistula flushing floating thread comprises a flushing catheter, wherein the front end of the flushing catheter is sealed; awater inlet is formed in the sidewall of the back side of the flushing catheter; a water outlet of the flushing catheter is positioned in the middle of the flushing catheter; the front end of the flushing catheter is detachably connected to the back end; and a burr area and length scales are arranged on the periphery of the middle section of the flushing catheter. The anal fistula flushing floating thread provided by the invention is convenient to operate and is simple and practical; flushing and drainage functions are integrated; lumens can be flushed; sufficient drainage can be guaranteed; and the anal fistula flushing floating thread can relieve pain in a patient accepting dressing changing, shorten a disease course and improve a cure rate of anal fistula.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a floating thread for flushing anal fistula. Background technique [0002] For patients with complex anal fistula or multi-cavity abscess, in order to protect the anal sphincter and cure the disease, floating suture drainage is often required after surgery, and the effect of floating suture drainage often affects the prognosis of the disease. Clinically, there is generally no special floating line for anal fistula irrigation catheter with irrigation function. Silk thread (sometimes multiple) or simple elastic is often used during operation, and the purpose of drainage is achieved through the silk thread or elastic itself. This way of drainage is not effective, and will increase the patient's discomfort. Contents of the invention [0003] The invention aims to provide an anal fistula flushing float, which has the functions of flushing and drainage. [0004] In order to...
