Abstract

The invention provides a taking-out device which comprises a clamping piece used for clamping and taking out a foreign matter; an outer sheath which is provided with a first channel used for containing the clamping piece; a second channel which is used for accommodating a visual mirror; a third channel which is used for instrument conveying or liquid flowing; a flexible part which is arranged at the far end of the outer sheath; at least one traction piece which is arranged in the outer sheath in a penetrating manner in the radial direction; and a holding part which is provided with a first control piece, wherein the first control piece is connected with the clamping piece and used for controlling the clamping piece to be in an unfolded state and a closed state. According to the device, the clamping piece, the visual mirror, instrument conveying or liquid flowing are integrated into the same device, the foreign matter can be taken out only by one operator, the foreign matter taking-out efficiency is improved, and the occurrence probability of secondary operation is reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, and in particular to a removal device for removing foreign bodies in the body. Background technique [0002] Single J tube and double J tube are more and more widely used in the treatment of kidney and ureter diseases as internal stent tube drainage, and good results have been achieved. However, long-term indwelling of single-J tubes and double-J tubes tends to grow crusts or concretions, making it difficult to extubate due to obstruction. Therefore, some scholars believe that the indwelling time of double J tubes should not be too long, the indwelling time of domestic double J tubes should not exceed 3 months, and the indwelling time of imported double J tubes should not exceed 6 months. [0003] In the case of direct vision, one person needs to hold a cystoscope or flexible ureteroscope to find the elbow of the double J tube in the bladder after transurethra...
