Embodiment

[0023] In this embodiment, mechanical motion and high-pressure air pump impact motion are included. The motor 210 is installed on the base 100, the motor 210 rotates, the driving gear 220 drives the rack 230 to move vertically and linearly, and at the same time, the corresponding driven gear 251 also rotates synchronously.

[0024] The base 100 is equipped with a slide rail 110 , the rack 230 is fixedly connected with the sliding sleeve 240 , and the rack 230 vertically moves up and down in the direction of the slide rail 110 .

[0025] The base 110 is rigidly fixed to the motor 210 and the slide rail 110 respectively, and the motor 210 is mounted with a waist hole design for fine-tuning installation.

[0026] The puncture needle assembly 400 is composed of a clamping needle part 440, a left jaw, and a right jaw, wherein the clamping needle part 440 and the sliding sleeve 240 are fixedly installed, and the left jaw and the right jaw are respectively designed with a semicircula...

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...
