Anal dilatation drug delivery device for proctology department

Abstract

The invention discloses an anal dilatation drug delivery device for a proctology department. The device comprises a frame body, an anal dilatation unit and a drug delivery device, wherein a bidirectional lead screw arranged in a front-back manner is rotatably connected to the frame body; a gear is arranged in the middle of the bidirectional lead screw in a sleeving mode; two sections of threads which are arranged at the front side and the rear side of the gear and are opposite in rotating direction are arranged on the bidirectional lead screw; the anal dilatation unit comprises two supports and two anal dilatation rods, and two supports are symmetrically arranged at the front side and the rear side of the gear and are connected with the bidirectional lead screw through the front and rear sections of threads; the two supports are connected with the frame body in a front-back sliding mode, the two supports correspond to two anal dilatation rods in a one-to-one mode, and the anal dilatation rods are transversely arranged at the left sides of the supports and are connected with the corresponding supports; the two anal dilatation rods are in front-back symmetry, and a gap is formed between the two anal dilatation rods; a transverse rack meshed with the upper edge of the gear is arranged above the gear, the rack is transversely connected with the frame body in a sliding mode, and thedrug delivery device is connected with the upper end face of the rack and is arranged between the two anal dilatation rods. The design is ingenious, the drug delivery time is shortened, and the painof a patient is relieved.

Description

technical field [0001] The invention relates to the technical field of anorectal medical devices, in particular to an anal-expanding drug delivery device for anorectal medicine. Background technique [0002] The traditional anal expander, when expanding the anus, there is no intermediate buffer time, and the patient's anus is instantly stretched to a certain extent. There are some improved anal expanders, although the patient's anus and anal canal can be gradually opened and closed. Controlled enlargement, but after the patient undergoes anal dilation, the anal dilator will be fixed, and the anus will be stretched to a certain extent for a long time, which will easily lead to chronic damage to the sphincter. [0003] Anal dilation of patients is mostly the preparatory stage for anorectal doctors to perform other procedures. For example, to examine patients and administer medicines, it is often necessary to dilate the anus first. However, dilation of the anus and administrati...

[0002] The traditional anal expander, when expanding the anus, there is no intermediate buffer time, and the patient's anus is instantly stretched to a certain extent. There are some improved anal expanders, although the patient's anus and anal canal can be gradually opened and closed. Controllable enlargement, but after the patient undergoes anal dilation, the anal dilator will be fixed, and the anus will be stretched at a certain range for a long time, which will easily lead to chronic damage to the sphincter

[0003] Anal dilation of patients is mostly the preparatory stage for anorectal doctors to perform other procedures. For example, to examine patients and administer medicines, it is often necessary to dilate the anus first. However, dilation of the anus and administration of medicines and inspections cannot be carried out at the same time, which increases the treatment time of the patient and makes Patients suffer longer

The degree of anal expansion determines how deep the drug delivery tube can enter the anal canal. If the anal canal wound is shallow, the anal expansion range can be smaller. If the anal canal wound is deep, the anal expansion range should be larger. Existing The anal expansion range of the anal dilator cannot change correspondingly with the depth of the drug delivery tube entering the anal canal
