Controllable formula anus intestines are with puncture hanging wire subassembly

Technical Field

The utility model relates to a disposable medical apparatus that is used for anus intestines branch of academic or vocational study fistulous way sexual disease, inflammatory disease and functional disease to treat specifically is a controllable formula anus intestines are with puncture hanging wire subassembly.

Background

Anorectal diseases refer to the generic term including anal, rectal, and colonic diseases. With the improvement of living standard and the change of eating habits of people, the incidence rate of anorectal diseases is increasing day by day, and the anorectal diseases become common diseases and frequently encountered diseases in daily life. The folk language of 'ten people nine hemorrhoids' is popular in China, which can explain the prevalence of anorectal diseases in people. The anorectal diseases can be suffered by both men and women, and can be suffered from diseases of adults and infants, and epidemiological data show that the incidence rate of anorectal diseases of adults is about 60-75%, wherein the incidence rate of adults in rural areas is higher than that of adults in cities. Although less dangerous, the more serious often affects the normal work and life, and even the less serious suffers from the suffering of the disease. Some babies suffer from anorectal diseases, which not only influences the development and growth, but also causes great burden to parents. The diagnosis and treatment of anorectal diseases are increasingly paid more attention by the masses.

The traditional Chinese medicine has the characteristics of simplicity, convenience, experience and low cost, and is widely applied to clinic. In recent years, the application range of the therapy is continuously expanded, the research on the therapy is also continuously deepened, and the therapy always occupies an important position in the anorectal diseases of the traditional Chinese medicine and is developed. The mechanism of the traditional thread-hanging therapy is quite clearly researched, and the traditional thread-hanging therapy is generally considered to have four major effects of chronic strangulation, foreign body stimulation, drainage and marking. The thread hanging operation is widely used clinically as a classic external treatment method of traditional Chinese medicine. Under the development of modern medicine, the thread-hanging operation is commonly used for anal fistula, perianal abscess, anorectal stenosis, chronic anal fissure and constipation with outlet obstruction, crohn's disease anal fistula and the like. The timely string of superficial line of high-order complicated anal fistula, perianal abscess keeps the drainage unobstructed, has both been favorable to the control state of an illness, has avoided the early healing of pipeline again, can not cause the damage to patient's perianal skin or subcutaneous tissue etc. has remain patient's anus function to the at utmost. In the stage of treating chronic inflammation of high anal fistula, a method of hanging a tightening wire is selected more, and the inner opening of the fistula is dissected due to the action of chronic cutting, so that the disease can be cured radically, and the function of protecting the anus can be achieved; the key points of the treatment of perianal abscess and anal fistula of infants lie in smooth drainage, treatment of internal orifice, excision of infection source and protection of anus. Generally, perianal abscess and anal fistula of infants are mostly in low positions. Direct excision of low superficial anal fistulas has been proven safe, but direct excision of the fistula should be avoided as much as possible because its sphincter development is not yet perfect. For those with complicated fistula shape or higher internal orifice, the fistula is cut at the lower position to form a high-position hanging line. The internal opening of the fistula can be enlarged by hanging the thread, so that smooth drainage is ensured, the growth of fresh granulation tissues is facilitated, the recovery is promoted, and the treatment time can be obviously shortened; when the thread-hanging therapy is used for treating anal fissure, all tension of the thread is usually utilized to gradually cut off part of internal sphincter and the pectinate band so as to relieve spasm symptoms of the internal sphincter of a patient, thereby gradually healing the split of the patient. The cutting by the method can avoid a series of sequelae such as anal deformation and incontinence caused by excessive cutting of the sphincter; for the treatment of benign or iatrogenic anorectal stenosis, the thread-hanging therapy has the advantages of slow cutting, long edge-cutting, compression hemostasis, anus protection function, simple and convenient operation and the like; for the constipation with outlet obstruction caused by the hypertrophy, spasm and the like of the puborectal muscle, the hung tissue is gradually necrotized and peeled off due to ischemia by cutting the hanging line of the puborectal muscle and depending on the chronic cutting action of the hanging line, thereby avoiding the adverse consequences of incision infection, sudden muscle disconnection, weakened anal canal self-control ability, even anal incontinence and the like caused by partial excision or cutting of the puborectal muscle.

At present, the treatment of the thread hanging therapy is clinically completed through a traditional probe, the top end of the traditional probe is spherical so as to be beneficial to exploration, the false cavity caused by sharp head is avoided, but sometimes, the fibrosis caused by the stimulation of chronic inflammation of a pipeline is heavier, a ball-head probe cannot smoothly pass through the pipeline, a rubber band or a plurality of silk threads are required to be connected with the spherical top end by the silk threads after the ball-head probe is extended out of an inner opening in the exploration process, when the rubber or the plurality of silk threads are led out of the pipeline, the silk threads are easy to fall off due to the reasons of muscle contraction or narrow pipe cavity and the like, so that the repeated puncture exploration is caused, and the operation difficulty and the operation time are increased; some doctors manually dilate and lead out the rubber band by using vascular forceps, and the operation violent tissue has larger injury and is easy to cause hemorrhage in the operation. After the published Chinese patent retrieval, the current novel probe invention presents the following 3 directions: 1. an annular strip line structure is arranged on one section of the probe, so that a hanging line can be conveniently led in. But the general problem is that the structure of the band wire is added secondarily, which increases the diameter of the probe and undoubtedly causes secondary dilatation to the inserted tissue, so as to cause complications such as bleeding; 2. the probe design is pipe hollow structure or extending structure to in doing fistula dyeing and tissue degree of depth measurement, this project organization is complicated, and the formation technological requirement and cost are all higher, and in clinical actual work we discover, and a lot of anal fistula lumens are narrow and small, can't pour into markers such as methylene into, and many perianal abscesses, anal fissure, anorectal stenosis, diseases such as pubic rectal muscle spasm also do not have the internal orifice, and practical application is not big, is unfavorable for clinical operation. In clinical trials, the hidden dead angle is found to cause the hidden dead angle due to the complex structure, so that cross infection hidden trouble is easily left in the repeated disinfection process of the instrument. 3. Part of the probe design adopts high polymer medical materials such as plastic silica gel or the like or different materials are adopted for connection in sections, but in actual clinic, the high polymer materials or the sectional type design do not have the excellent characteristics of hardness and flexibility, and the application value is not large. The problem that all have above design to solve is the problem of fixed elasticity regulation behind the hanging wire, and the line tightening operation is loaded down with trivial details many times, and the patient is painful. For many years, anorectal department for treating the diseases adopts repeated disinfection instruments, so that a disposable special medical instrument for thread hanging is clinically needed, and the medical instrument has good puncture property, thread hanging stability, simplicity and convenience in operation, adjustable thread hanging force and switchable virtual and real thread hanging. The product fills the gap that no disposable special instrument is used in the field of anorectal diseases.
