Microtubule inverting and reclamping device

Abstract

The invention discloses a microtubule inverting and reclamping device, belonging to the field of iodine (125I) sealing seed source preparation equipment. The device comprises a rotary drum support, a rotary drum, a swing cylinder, a positioning device and two chuck driving mechanisms, wherein the rotary drum is a round hollow structure with at least one open end, the rotary drum is movably arranged on the rotary drum support, the swing cylinder is connected with the rotary drum and can drive the rotary drum to rotate on the rotary drum support for at least 180 degrees; the rotary drum is internally provided with the positioning device which can mount and position two modular fixtures, the two chuck driving mechanisms are respectively oppositely arranged outside the rotary drum, and the front end of each chuck driving mechanism is corresponding to the bottom end of the modular fixture arranged on the positioning device in the rotary drum. The microtubule inverting and reclamping device disclosed by the invention has simple structure, is convenient to operate and can automatically complete inverting and reclamping of microtubules in the two modular fixtures; meanwhile, a transfer path of the microtubules during inverting is the shortest and transmission accuracy is high, preparation time is effectively shortened, and personnel can be protected by receiving less radioactive irradiation.

Description

technical field [0001] The present invention relates to iodine[ 125 I] sealed seed source preparation equipment field, especially relate to a kind of preparation iodine [ 125 i] Sealed seed source microtube upside-down re-clamping device. Background technique [0002] iodine[ 125 I] Sealed seed source is a drug used for internal radiation therapy implanted between close-range tissues. It is implanted into solid tumors through puncture technology, and can act on tumors continuously for a long time. In the existing iodine [ 125 1] the preparation field of sealed seed source, semi-finished product welding (hereinafter referred to as cold welding) and finished product welding (hereinafter referred to as heat welding) of titanium tube need weld the two ends of titanium tube respectively, finish iodine [ 125 I] The cold welding and hot welding of the sealed seed source are carried out at two stations respectively, and the micropipe is to be reversed between the two links. At p...
