Abstract

The anorectal postoperative analgesia and hemostasis device comprises a fixed part and a movable part, and the movable part is arranged in the fixed part and can move relative to the fixed part; the fixing piece comprises a fixing sleeve, an elastic sleeve and a fixing base, the fixing sleeve and the elastic sleeve are both in a circular tube shape, one end of the fixing sleeve is in sealed connection with one end of the elastic sleeve, the other end of the elastic sleeve is in sealed connection with the fixing base, and a plurality of medicine penetrating holes are formed in the outer side face of the elastic sleeve at equal intervals in the radial direction of the elastic sleeve; internal threads are arranged on the inner side face of the fixed sleeve, external threads are arranged on the outer side face of the movable piece, and one end of the movable piece extends into the fixed sleeve and is in threaded connection with the internal threads on the inner side face of the fixed sleeve through the external threads on the outer side face of the movable piece. The movable piece and the fixed piece are connected to form a hollow cavity, and liquid medicine is arranged in the hollow cavity.

Description

technical field [0001] The invention relates to the field of anorectal surgery, in particular to an analgesic and hemostatic device after anorectal surgery. Background technique [0002] At present, the treatment of incisional pain after anorectal surgery is an international problem. Most of the analgesic methods are systemic administration. The effect of pain medicine is not good, the dosage and frequency of injection of analgesic morphine need to be controlled, and the use of analgesic pump is cumbersome and often has complications. Systemic administration will inevitably affect the function of important organs due to drug toxicity. However, the existing analgesic and hemostatic devices after anorectal surgery are equipped with outwardly protruding oval medicine bags, which will cause certain damage to the muscles around the wound when they are inserted into the anorectal. Therefore, it is necessary to study a new anorectal postoperative analgesic and hemostatic device to...

[0002] At present, the treatment of incisional pain after anorectal surgery is an international problem. Most of the analgesic methods are systemic administration. The effect of pain medicine is not good, the dosage and frequency of injection of analgesic morphine need to be controlled, and the use of analgesic pump is cumbersome and often has complications. Systemic administration will inevitably affect the function of important organs due to drug toxicity. However, the existing analgesic and hemostatic devices after anorectal surgery are all equipped with outwardly protruding oval medicine bags, which will cause certain damage to the muscles around the wound when inserted into the anorectal. Therefore, it is necessary to study a new type of postoperative analgesia and hemostasis device for anorectal surgery to solve the above problems
