In-vivo introduction control device

Abstract

The invention relates to an in-vivo introduction control device. The device comprises a catheter, a pushing mechanism, a rope driving module, a rope fixing module and a controller, wherein the pushingmechanism is used for driving a guide pipe to move forwards and backwards; the catheter is integrated by a plurality of sectional catheters connected in series, and through holes distributed in the longitudinal direction of each sectional catheter are formed inside the corresponding sectional catheter; skeleton springs and guide wires are distributed in the longitudinal direction of each sectional catheter and are arranged on the catheter wall; the guide wires in one or more sectional catheters at the end, away from the pushing module, of the catheter are connected with the rope driving modules in a one-to-one correspondence mode; the guide wires in the rest sectional catheters in the catheter are connected with the rope fixing module in a one-to-one correspondence manner; the rope driving module and the pushing mechanism are both connected with the controller; and the rope driving module comprises a motor driving mechanism, and the output end of the motor driving mechanism is connected with the guide wires and are used for winding and releasing the guide wires. Compared with the prior art, the in-vivo introduction control device has the advantages that the bronchial wall of a patient is relatively small damaged, smaller bronchial branches can be accessed, the precision is higher, the operation is convenient, and the like.

Description

technical field [0001] The invention relates to the technical field of in vivo introduction, in particular to a control device for in vivo introduction. Background technique [0002] Bronchial lung cancer (referred to as lung cancer) is a malignant tumor with the highest morbidity and mortality in the world. In recent years, the morbidity and mortality have been increasing year by year. Surgery is still the most effective treatment for lung cancer at present. However, due to the non-specific clinical manifestations of early lung cancer, most patients have missed the opportunity for surgery when they are diagnosed with lung cancer, and the overall effect of current chemotherapy and radiotherapy is not ideal. Early diagnosis and surgery are the key to improving the survival of lung cancer patients, so how to accurately identify and diagnose lung cancer technology at an early stage is very important. [0003] At present, the commonly used method for early screening of lung can...
