Assistant puncture device for medullo-puncture needle

Abstract

The invention discloses an assistant puncture device for a medullo-puncture needle, and belongs to the technical field of medullo-puncture needle puncture equipment. The assistant puncture device aims at solving the technical problems that when an existing medullo-puncture needle is in use, no assistant puncture equipment is available, time and labor are wasted, and great pain is brought to a patient. The assistant puncture device comprises a guide cap device, a puncture box, a rotating device, a braking device, a feeding device and a fixing tooth device. The fixing tooth device is arranged at the root of a medullo-puncture needle adjusting thread. An inner cavity of a shell of the puncture box is divided into a sliding block feeding cavity, a medullo-puncture needle installation cavity and a rotation driving cavity from front to back, and the medullo-puncture needle installation cavity is communicated with the sliding block feeding cavity and the rotation driving cavity. A push handle guide groove is formed in the front side wall of the sliding block feeding cavity. The rotating device is arranged in the rotation driving cavity. The guide cap device is connected with the left end of the shell through threads. The medullo-puncture needle is arranged in the medullo-puncture needle installation cavity. The assistant puncture device has the advantages of being simple, convenient and fast to use and easy to operate, increasing the success rate of bone marrow puncture and relieving the intensity of clinical work.

Description

technical field [0001] The invention belongs to the technical field of bone puncture needle puncture equipment, and in particular relates to a bone puncture needle auxiliary puncture device. Background technique [0002] All-metal bone puncture needles are widely used in various medical units as an indispensable medical device for clinical implementation of bone marrow puncture and extraction of bone marrow fluid samples for testing. The bone puncture needle consists of three parts: the needle handle, the needle body and the needle core: the needle body is hollow and contains the needle core; the needle handle is composed of a front force plate, an adjusting screw, and a fixed screw, which can adjust the depth of puncture. The existing bone puncture needles do not have auxiliary puncture equipment during use, and doctors can only rely on the power of the palm to complete the puncture work of the bone puncture needle, which takes time and effort and brings great pain to the p...
