Embodiment 1

[0027] Embodiment 1 provides a pneumatic puncture device, the structure of which will be described in detail below.

[0028] refer to figure 1 , the pneumatic puncture operation device includes a support, a first planar movement mechanism, a second planar movement mechanism and a puncture needle mechanism. Wherein, the first planar movement mechanism includes a first movement pair 11 and a second movement pair 12, the second planar movement mechanism includes a third movement pair 13 and a fourth movement pair 14, and the puncture needle mechanism includes a needle cylinder 21 and a puncture needle 22. .

[0029] Wherein, the support includes a base 10 and a vertical plate 100 , and the vertical plate 100 is vertically fixed on the base 10 .

[0030] The fixed ends of the first mobile pair 11 and the third mobile pair 13 are arranged on the vertical plate 100; the second mobile pair 12 and the fourth mobile pair 14 are respectively connected with the free ends of the first m...

Abstract

The invention discloses a pneumatic puncture operation device, comprising a vertical plate, a first plane moving mechanism, a second plane moving mechanism and a puncture needle mechanism, the first plane moving mechanism includes a first moving pair and a second moving pair, the second plane moving mechanism The moving mechanism includes a third moving pair and a fourth moving pair, and the puncture needle mechanism includes a needle cylinder and a puncture needle. The invention is disclosed. The pneumatic puncture operation device disclosed in the present invention fills the longitudinal pneumatic artificial muscle, the horizontal pneumatic artificial muscle and the needle insertion pneumatic artificial muscle with compressed gas by controlling the compressor, and controls the spatial position of the puncture needle and the advance and retreat of the needle head in the form of pneumatic drive. The positioning accuracy of the puncture needle during the puncture operation has been greatly improved. In addition, the pneumatic artificial muscle is used as the drive instead of the electric drive, so the parts used do not need to be made of metal, so the pneumatic device for the puncture operation can follow the The patient undergoes a CT scan together.

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...
