AI Technical Summary

Technical Problem

Existing injection methods for esophageal cancer treatment are complicated to perform due to esophageal stenosis, are physically demanding for doctors, and are difficult to inject from multiple angles.

Method used

An oncology drug delivery device was designed, comprising an in-depth treatment chamber, an adjustment tube, an angle adjustment mechanism, and an injection head. Guided by an endoscope, the angle of the adjustment tube is adjusted using a control handle and an adjustment wheel assembly. Combined with a limiting chamber and a positioning airbag, the device ensures stable insertion of the injection head and multi-angle injection.

Benefits of technology

It simplifies the esophageal injection procedure, reduces the workload for doctors, enables multi-angle injection into the esophageal cancer lesion area, and improves the convenience and effectiveness of treatment.

Abstract

The present invention relates to the technical field of esophageal injection, and discloses an oncology drug delivery device and a method of using the device, comprising a deep treatment chamber inserted into the body and a control handle installed at the far end of the deep treatment chamber and connected by a pipeline, the side of the deep treatment chamber is rotatably connected with an adjustment tube for guiding the injection direction, and both sides of the adjustment tube are installed with an angle adjustment mechanism for cooperating with the control handle to control the rotation; when the deep treatment chamber can be inserted through the oral cavity, the angle of the adjustment tube on the side of the deep treatment chamber is driven to change through the cooperation of the external control handle and the adjustment wheel group, the whole adjustment process is simple and convenient, the injection head is tilted for injection, and the control is very convenient during flat injection, and the injection for nipple-type conditions avoids the influence of the protruding structure on the injection, and the multi-angle switching injection for injection treatment of the center, base and edge of the tumor is more suitable, which reduces the operation intensity of the doctor.
