An anorectal inspection and drug delivery device

Abstract

The invention discloses an anorectum checking and drug delivering device. The anorectum checking and drug delivering device comprises an outer cannula, an inner cannula, a drug deliverer and a biopsy device. The outer cannula and the inner cannula are both of a conical structure. The outer cannula comprises an inner layer and an outer layer. The outer layer covers the inner layer from the conical bottom face of the inner layer directly to the lower middle portion of the inner layer. The inner layer and the outer layer are connected only through a fixing end, a drug deliverer containing bin is arranged in the space between the inner layer and the outer layer, an annular drug deliverer inserting opening is formed in the bottom of the drug deliverer containing bin, and a drug delivery outlet is formed in the top of the drug deliverer containing bin. The drug deliverer is arranged in the drug deliverer containing bin and can move along the drug deliverer containing bin within the axial 360-degree range. A gap is reserved in the conical top end of the outer cannula and serves as an inner cannula extension opening, and the upper end of the inner cannula stretches out of the inner cannula extension opening. An opening is formed in the side face of the top of the inner cannula, the biopsy device is arranged in the inner cannula, and the sampling end of the biopsy device stretches out of the opening. The interior of the anorectum can be checked, sampled and subjected to drug delivery, and the anorectum checking and drug delivering device is simple in structure and convenient and rapid to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anorectal examination and drug delivery device.
