Problems solved by technology
[0005] In order to solve the above-mentioned technical problems, the present invention provides a drug delivery device for cancer targeting in the digestive tract to solve the problems existing in the actual application of existing drug delivery devices. There will be a lot of drugs to be injected, so when the injection liquid is changed frequently, the injection position will be shifted due to the inability of the pillow injected into the body to effectively limit the position, which will lead to the failure of targeted drug delivery. It is impossible to fully mix the medicinal liquid while injecting multiple medicinal liquids, which will lead to the problem that the medicinal liquid effect of the targeted drug is poor

Embodiment
[0030] as attached figure 1 to attach Image 6 Shown:
[0031] The present invention provides a targeted drug delivery device for cancer in the digestive tract, which includes: a binding mechanism 1 and a driving mechanism 5, a limit mechanism 2 is installed on the inner side of the binding mechanism 1, and the right side of the binding mechanism 1 is also snapped There is a bearing mechanism 3, which is fixed by bolts; the driving mechanism 5 is installed at the top position of the bearing mechanism 3, and is connected in transmission with the propulsion mechanism 4 in the bearing mechanism 3; the driving mechanism 5 includes a driving gear 501, a bevel gear set 502, The driven gear 503 and the chain 504, the tooth size and tooth spacing of the driving gear 501 are consistent with the top rack size and tooth spacing of the push rod 402, and the driven gear 503 is provided with two places, and the outer sides of the two driven gears 503 A chain 504 is meshed, wherein a bevel...

The invention provides a targeted drug delivery and delivery device for cancers in digestive tracts, relates to the technical field of targeted drug delivery, and solves the problems that in the practical application process of an existing drug delivery device, a large number of drugs are required to be injected when targeted injection is performed on a patient, therefore, a pillow for injecting liquid medicine into a body cannot effectively limit the pillow when the liquid medicine is frequently replaced, the injection position deviates, then targeted drug delivery fails, the liquid medicine cannot be fully mixed while multiple kinds of liquid medicine are injected, a constraint mechanism is included, and a limiting mechanism is installed on the inner side of the constraint mechanism. In the invention, the tooth size and the tooth space of a driving gear in the driving mechanism are consistent with the size and the tooth space of a rack at the top end of a pushing rod. Therefore, when the pushing rod moves, the pipe body can be rotated through a bevel gear set by virtue of meshing transmission between a driven gear and a chain, so that the aim of uniformly mixing liquid medicine is fulfilled.
Description
technical field [0001] The invention belongs to the technical field of targeted drug delivery, and more specifically relates to a targeted drug delivery device for cancer in the digestive tract. Background technique [0002] Targeted drug delivery system, using the carrier to selectively concentrate the drug on the lesion or a specific part of the body, so that the drug can play a maximum role in the lesion, while the systemic side effects are minimized, including: (1) Passive targeting preparations, insoluble drug-loaded particles (such as liposomes, nanocapsules, etc.) rely on body cell phagocytosis to allow drugs to enter the target area, (2) active targeting preparations, using antibodies and other modified drug carriers as "missiles", will The drug is delivered to the target area in a directional manner. (3) Physicochemical targeting preparations, using magnetic materials, temperature-sensitive or pH-sensitive carriers, enable the drug to exert its curative effect at a ...
