Drug delivery device for medical oncology and use method of drug delivery device

Abstract

The invention relates to the technical field of esophageal injection, and discloses a medical oncology drug delivery device and a use method thereof.The medical oncology drug delivery device comprises a deep treatment bin penetrating into the body and a control handle installed at the far end of the deep treatment bin and connected with the deep treatment bin through a pipeline; the side face of the deep treatment bin is rotationally connected with an adjusting pipe used for guiding the injection direction, and angle adjusting mechanisms used for being matched with the control handle to control rotation are installed on the two sides of the adjusting pipe. When the deep treatment bin is inserted into the oral cavity, the external control handle is matched with the adjusting wheel set to drive the angle of the adjusting pipe on the side face of the deep treatment bin to change, the whole adjusting process is simple and convenient, and the injection head is very convenient to control during inclined injection and flat injection; in addition, the influence of a convex structure on injection is avoided aiming at the injection of nipple type diseases, the multi-angle switching injection for injection treatment aiming at the center, the basal part and the edge part of a tumor is more suitable, and the operation intensity of a doctor is reduced.

Description

technical field [0001] The invention relates to the technical field of esophagus injection, in particular to a drug delivery device for medical oncology and its application method. Background technique [0002] Tumor refers to the new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors. For internal medicine, compared with surgery, most of the internal tumors are located inside the body. In terms of esophageal cancer, the internal lesions of the esophagus are mainly divided into four types: hidden type, plaque type, erosive type and papillary type. Shaped, or mushroom-shaped, protruding into the esophageal cavity, in the local injection treatment of esophageal cancer, the injection treatment is generally performed at the center, base and edge of the tumor. [0003] The existing injection method is mainly through the gastroscope and the endoscopic injection needle for injection. The inner diameter injection needle is com...

Problems solved by technology

[0003] The existing injection method is mainly through the gastroscope and the endoscopic injection needle for injection. The inner diameter injection needle is composed of a sheath, needle, joint and other structures. The sheath follows the gastroscope and is inserted into the interior for injection. On the side of the esophagus, the diameter of the esophagus is narrow, and it is troublesome to operate and control when injecting the esophagus. In fact, the distance between the esophagus and the incisors is not long, so this injection method makes the injection process more complicated. , requires multiple injections, thus making the injection treatment process too wasteful for the doctor
