Abstract

The invention discloses an anesthesia department epidural puncture needle inserting device and belongs to the technical field of medical instruments, the anesthesia department epidural puncture needle inserting device comprises a fixing plate, a push rod motor is arranged in the middle of the fixing plate, a needle inserting shell is arranged at the lower end of the push rod motor, and a double-end lead screw is arranged in the needle inserting shell. The telescopic end of the push rod motor slowly drives the puncture needle to enter a puncture part, the mounting base moves to enable the air bag to be deflated and shrunken, the mounting base moves to drive the connecting frame to move, the elastic contact piece at the upper end of the connecting frame moves to be attached to the fixed contact piece to be powered on, and the control panel controls the indicator lamp and the loudspeaker to work, the indicator lamp displays light, the loudspeaker broadcasts voice and achieves multi-mode reminding. Needle insertion can be conveniently and accurately stopped; the adjustable grip is arranged at the upper end of the fixing plate, the screw rod is rotated by rotating the adjusting disc, the screw rod ascends and descends in the stand column, the height of the grip rod is changed, holding of different hand types is achieved, and different use requirements are met.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an epidural puncture needle insertion device in an anesthesiology department. Background technique [0002] Anesthesiology is a comprehensive discipline that contains multidisciplinary knowledge. The scope is very wide, not only to meet the requirements of surgery, but also to participate in the rescue work of various departments, painless childbirth in gynecology, painless abortion and so on. [0003] The prior art has the following problems: the existing anesthesiology epidural puncture needle insertion device exists in use: 1. After the puncture needle is inserted, it is troublesome and inaccurate to rely on the deflated airbag to judge the needle insertion, the reminder method is single, and the effect is ineffective. Good, there is safety in use; 2. The handle is not adjustable, and the palms of different doctors are different, which causes inconvenience...
