Abstract

The invention discloses a pneumatic puncture operation device. The device comprises a vertical plate, a first plane moving mechanism, a second plane moving mechanism and a puncture needle mechanism. The first plane moving mechanism comprises a first moving pair and a second moving pair, the second plane moving mechanism comprises a third moving pair and a fourth moving pair, and the puncture needle mechanism comprises a needle feeding cylinder and a puncture needle. According to the pneumatic puncture operation device, a compressor is controlled to inflate compressed air into the longitudinal pneumatic artificial muscle, the transverse pneumatic artificial muscle and the needle inserting pneumatic artificial muscle, and the space position of the puncture needle and advancing and retreating of a needle head of the puncture needle are controlled in a pneumatic driving mode. The positioning accuracy of the puncture needle in the puncture operation process is greatly improved. In addition, the pneumatic artificial muscle, instead of electric drive, is used as a drive, so that used parts can not be made of metal materials, and the pneumatic puncture operation device can carry out CT scanning along with a patient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pneumatic puncture operation device. Background technique [0002] Puncture surgery has become a common surgical method because of its small wound and minimal harm to patients, and is widely used in tissue biopsy, tumor ablation, and drug injection. In the current puncture operation, there is a problem of low positioning accuracy of the puncture needle. Doctors need to try many times to actually insert it to the target position, which prolongs the operation time and increases the pain suffered by the patient. In addition, because the drive of the existing puncture operation device all adopts a motor, and the motor and its electrically connected parts are inevitably not made of metal, therefore, when using the existing puncture operation device to perform a CT scan on a patient, it is easy to This causes metal artifacts in the scanned image, so it is impossible to o...
