Description

Contain medicine gel filling device suitable for non-surgical treatment of anal fistula

Technical Field

The utility model belongs to the technical field of the medicine filling device, in particular to contain medicine gel filling device suitable for non-operation treatment of anal fistula.

Background

Anal fistula is a short term for anorectal fistula and is a residual lesion caused by abscess rupture or incision drainage around the anorectum. The multiple population is 20-40 years old and male infants. Clinically, a probe is used to probe from the external orifice of the anal fistula, and the probe can probe to the internal orifice as long as the fistula is smooth. During operation, the fistula is cut along the probe. The use of a probe to locate the internal orifice requires both cases, the middle of the fistula is blocked and the fistula is tortuous. The probe cannot move when the fistula is bent, and the liquid needs to be filled from the outer opening, and the liquid flows out from the outer opening, and the outflow position is the inner opening.

Typical surgical treatments include: (1) the anal fistula drainage is cut and infected in the outbreak period, and at the moment, because other factors of the body can not be operated, the anal fistula drainage can be cut on the surface of an infected focus for drainage or the purulence extraction treatment can be carried out by a syringe. The method has an instant effect, but only temporarily relieves the disease, and a radical operation is needed to be performed in the future. (2) The catheter or the thread is used for drainage, the operation is not mastered for the complicated fistula with high fistula or multiple fistulas, but in order to prevent the disease condition from aggravating or spreading, the drainage catheter or the drainage strip can be placed in the fistula, and the disease condition can be controlled although the medicine is washed every day. (3) Anal fistula incision anal fistula is the most classical and mainstream surgical method, and more than 90% of low anal fistula treatments adopt the method. (4) Fistula removal can be used for completely adhering fistula, thin low anal fistula and probe insertability. (5) The main focus incision branch tube open surgery is applicable to various complicated anal fistulas. When in operation, the main focus is firstly positioned, and the fistula at the inner opening and the anal canal is directly cut. And performing dilation on the external orifice. The fistula between the external opening and the main stove is opened, and a drainage strip or a drainage tube is placed. And (5) dismantling after 7-10 days. (6) Fistula packing takes into account that both dissection and removal will break the anal sphincter through which the fistula passes, and attempts have been made at home and abroad to pack the fistula with some special materials that will cure the fistula without injuring the anal muscles. These materials include fibrin glue, bioremediation plugs made of freeze-dried porcine small intestine submucosa acellular matrix, and the like. The method has very harsh application conditions, complete and smooth fistula and clear internal and external orifices. The treatment will fail due to the outflow of the tamponade agent or the appearance of infection after surgery. At present, the traditional Chinese medicine composition cannot be widely applied to clinic as an alternative therapy.
