Needle holding and inserting puncture device

Abstract

The invention discloses a needle holding and inserting puncture device which comprises a support and a stroke pipe rotationally installed on the support, a driven gear is fixedly installed on the outer side wall of the stroke pipe, a servo motor for driving the stroke pipe to rotate can be further installed on the support, any end of the stroke pipe is detachably connected with a connector in a sealed mode, a through hole used for containing a puncture needle is formed in the other end of the stroke pipe, a piston is arranged in the stroke pipe in a sliding mode in the axial direction, the piston and the stroke pipe rotate synchronously, a connecting part used for being detachably connected with the puncture needle is arranged on the end face of the end, close to the through hole, of the piston, a pipeline communicated with the stroke pipe is arranged on the connector for closed rotation, and the other end of the pipeline is connected with a pressure control device. Rotation and axial movement of the puncture needle are achieved through rotation of the stroke pipe and pressure driving, separation is achieved, the axial feeding amount and the rotating speed can be independently controlled, adjustment of different pressures can be achieved according to different bone tissues, and the purpose of adjusting the feeding amount is achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to the technical field of automatic puncture equipment with a needle held by a mechanical arm, and in particular to a needle-held puncture device. Background technique [0002] Tumor is a major problem faced by medical technology worldwide today. According to the International Agency for Research on Cancer (IARC), in recent years, there are nearly 20 million new cancer patients in the world every year, and nearly 10 million people die because of tumors. Although there are many effective treatment methods for tumors in the existing medical technology, due to the early onset of tumors, there are often no symptoms, which makes early detection and early treatment difficult. Therefore, for example, the method of achieving recovery through surgical resection is not suitable for large Some tumor patients; the remaining treatment methods are usually radiotherapy and chemotherapy a...
