A device for analgesia and hemostasis after anorectal surgery

Abstract

The invention discloses analgesia and hemostasis device after anorectal surgery, which comprises a fixed part and a movable part. The movable part is arranged in the fixed part and can move relative to the fixed part; , the fixed sleeve and the elastic sleeve are both in the shape of a round tube, one end of the fixed sleeve is sealed and connected to one end of the elastic sleeve, the other end of the elastic sleeve is sealed and connected to the fixing seat, and the outer surface of the elastic sleeve is arranged at equal intervals along the radial direction of the elastic sleeve There are several drug penetration holes; the inner surface of the fixed sleeve is provided with internal threads, the outer surface of the movable part is provided with external threads, and one end of the movable part extends into the fixed sleeve and passes through the external threads on the outer surface of the movable part and the fixed sleeve. The internal thread on the inner surface is threaded; the movable part is connected with the fixed part to form a hollow cavity, and the liquid medicine is arranged in the hollow cavity.

Description

technical field [0001] The invention relates to the field of anorectal department, in particular to an analgesic and hemostasis device after anorectal surgery. Background technique [0002] At present, the treatment of incision pain after anorectal surgery is an international problem. Most of the analgesic methods are systemic administration, traditional methods of oral and injection analgesics, intravenous and epidural analgesic pumps, and oral analgesia. Pain medicine is not effective, injection of analgesic morphine needs to control the dosage and frequency, the use of analgesic pump is cumbersome and common complications, systemic administration will inevitably affect the toxicity of the drug and affect the function of important organs, therefore, it is necessary to use plug The implantable local analgesic and hemostatic device is operated, but the outside of the existing anorectal postoperative analgesic and hemostatic device is provided with an outwardly protruding ell...

Problems solved by technology

[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
