Description

Technical Field

[0001] The invention relates to the technical field of postoperative drug administration, in particular to a postoperative drug administration device for anorectal surgery. Background Art

[0002] Anorectal diseases are common and frequently occurring diseases. Anorectal surgical diseases refer to all diseases occurring within the anus, rectum, colon and ileocecal region. It is generally believed that anorectal surgery seems to mainly treat anal diseases such as hemorrhoids, anal fistulas, and anal fissures. This is a narrow understanding. In addition to the above common diseases, the treatment scope of anorectal surgery is also very broad. Generally speaking, anorectal surgery treats all diseases of the large intestine and anal canal. Most anorectal surgeries require drug treatment after surgery.

[0003] After anorectal surgery, the surgical incision often causes great pain, which brings great psychological and physical burdens to patients and seriously affects their recovery. After existing anorectal surgery, patients are generally given oral analgesics or injected analgesic liquids. This method cannot directly correspond to the poor analgesic effect of surgical wounds, and requires continuous oral or injected drugs, which is cumbersome to operate and inconvenient for patients to use for rehabilitation. In the related art, the threaded rod, threaded hole, L-shaped sliding rod, sliding hole and rotating wheel are set, and the rotating wheel can be rotated to drive the threaded rod to rotate. The threaded connection between the threaded rod and the threaded hole is used to drive the support plate to move up and down. The movement of the liquid storage cylinder and the injection probe is driven by the cooperation of the telescopic tube, and the displacement of the injection probe is accurately adjusted by the provided scale, so that the injection probe is located at the incision of the patient. By cooperating with the micro pump, the drainage tube and the suction tube, the incision of the patient is directly administered, which effectively increases the analgesic effect on the patient. However, in actual use, its structure is relatively complex, and the two threaded rods need to be rotated at the same frequency, resulting in high difficulty in operation, and the threaded rod needs to be continuously rotated to reach the drug administration position, which makes it less efficient and has certain limitations.

[0037] After anorectal surgery, the surgical incision often causes great pain, which puts a great psychological and physical burden on the patient and seriously affects the patient's recovery. After existing anorectal surgery, patients are generally given oral painkillers or injected analgesics. This method cannot directly respond to the analgesic effect of the surgical wound and requires continuous oral or injected medication, which is cumbersome to operate and inconvenient for patients' recovery.

[0038] In the related art, by setting a threaded rod, a threaded hole, an L-shaped sliding rod, a sliding hole and a rotating wheel, the rotating wheel can be rotated to drive the threaded rod to rotate, and the threaded connection between the threaded rod and the threaded hole can be used to drive the support plate to move up and down. Through the cooperation of the telescopic tube, the movement of the liquid storage cylinder and the injection probe is driven, and the displacement of the injection probe is precisely adjusted through the set scale, so that the injection probe is located at the patient's incision. Through the cooperation with a micro pump, a discharge tube and a suction tube, the patient's incision can be directly dosed, effectively increasing the analgesic effect on the patient. However, in actual use, its structure is relatively complicated, and the two threaded rods need to be rotated at the same frequency, which makes its operation difficult, and the threaded rod needs to be continuously rotated to reach the drug delivery position, which makes it less efficient and has certain limitations.

[0039] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a post-operative drug delivery device for anorectal surgery. When it is needed, it is only necessary to manually push the drug delivery tube 14 directly to make the drug delivery tube 14 slide upward in the ring body 21, and then insert the drug delivery head 15 directly into the patient's anorectal rectum to a specified depth. By observing the scale bar on the drug delivery tube 14 and manually rotating the ring body 24, the drug delivery tube 14 and the drug delivery head 15 continue to move deeper until they reach the specified depth. By injecting medicine into the drug delivery tube 14, the post-operative drug delivery operation of anorectal surgery is realized, which is more convenient and quick, thereby improving the convenience of the device.
