Automatic impact needle insertion puncturing device

Abstract

An automatic impact needle insertion puncturing device comprises a base, a mechanical motion positioning mechanism, a high-pressure air pump impact mechanism and a puncture needle assembly, wherein the mechanical motion positioning mechanism comprises a motor, a driving gear and a rack part; the motor is fixedly mounted on the upper portion of the base; an output shaft of the motor is in driving connection with the driving gear; the driving gear is meshed with the rack part; a sliding rail is fixedly installed on the base; the rack part is fixedly installed on a sliding sleeve; and the slidingsleeve is arranged on the outer side of the sliding rail in a sleeving mode and can move along with the sliding rail. Compared with the prior art, the automatic impact needle insertion puncturing device overcomes defects of traditional manual puncturing, and meanwhile, dual driving forces of machinery and high-pressure air pump impact are matched; the mechanical motion plays a role in positioning, and the high-pressure air pump impact plays a role in rapid puncturing, so that the acting effect of the device is superior to that of manual operation and pure mechanical needle insertion, the problem of needle drifting during insertion can be effectively solved, the puncturing process is completed accurately and efficiently, and the human dependence is reduced; and meanwhile, the operation risk is reduced, and the operation success rate is increased.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic impact needle puncture device. Background technique [0002] In the medical field, the surgical needle insertion during soft tissue biopsy and ablation surgery is generally performed manually by doctors, and the process largely depends on the operator's personal experience and is relatively labor-intensive. A common problem, especially when encountering a hard tissue, the speed of manual needle insertion is relatively slow, the tissue displacement is easy to move, and it is difficult for the needle to accurately reach the lesion, which brings great risks to the operation. reduce the success rate of surgery. Contents of the invention [0003] In view of the above defects in the prior art, the present invention provides an automatic impact needle puncture device as follows: [0004] Technical scheme of the present invention is realized like this: [0005...
