Problems solved by technology
[0002] Ordinary puncture guides are usually made of plastic materials. Due to material problems, the puncture guide will generate a lot of friction when rotating, which is prone to jamming, which is not conducive to actual operation, and the accuracy of adjusting the angle cannot meet the standard. At the same time, it is very inconvenient to sterilize the guide after use, and it is easy to cause pollution. In order to solve the above problems, it is very necessary to design a new puncture guide

Embodiment
[0022] When guiding the puncture, first determine the puncture angle according to the actual situation. After the angle is determined, open the locking screw on the indicator protrusion 3 and the positioning bolt on the auxiliary positioning block 4, and then turn the metal rotating ring 2, and the metal rotating ring 2 Align the pointer on the indicator protrusion 3 with the selected angle, then tighten the locking screw and the positioning bolt, and then place the whole device on the puncture position of the patient, when the water bubble in the conical level 9 is at the top inside the conical level 9 , indicating that the angles are aligned, and the nursing staff punctures the patient's puncturing position from the insertion slot 12 of the guide bar 5 .
[0023] The whole equipment is made of metal material, and the conical level 9 is made of high-hardness glass, so the device has a long service life and is easy to disinfect.

The invention relates to a metal type puncture guiding device. The metal type puncture guiding device comprises a metal dial, a metal rotating ring and an indicating protrusion, wherein the metal dialis of a cylindrical structure; a front-part circular groove and a mounting circular groove are arranged at the front side and the rear side of the metal dial respectively; the metal rotating ring isrotatably arranged in the mounting circular groove; a circle of angle scales are arranged at the periphery of the metal dial; the 0-degree position of the angle scales is located at the uppermost position of the metal dial; the indicating protrusion is arranged at the upper end of the metal rotating ring and is higher than the metal dial; the front end of the indicating protrusion extends toward the direction of the metal dial; a locking screw with the lower end penetrating through an extending end of the indicating protrusion to abut against the metal dial is vertically arranged on the extending end of the indicating protrusion; a guiding strip with the upper end corresponding to the indicating protrusion is vertically arranged at the rear side of the metal rotating ring; and a steel strip with the upper end aligned with a 0-degree scale is arranged on the side wall of the front-part circular groove. The metal type puncture guiding device provided by the invention has the characteristics of easy adjustment, flexible rotation, high rotation angle accuracy, convenience in equipment disinfection, long service life and the like.
Description
technical field [0001] The invention relates to the technical field of puncture guidance, in particular to a metal puncture guide. Background technique [0002] Ordinary puncture guides are usually made of plastic materials. Due to material problems, the puncture guide will generate a lot of friction when rotating, which is prone to jamming, which is not conducive to actual operation, and the accuracy of adjusting the angle cannot meet the standard. At the same time, it is very inconvenient to sterilize the guide after use, and it is easy to cause pollution. In order to solve the above problems, it is very necessary to design a new puncture guide. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a metal puncture guide, which has the characteristics of simple adjustment, flexible rotation, high accuracy of rotation angle, convenient equipment disinfection and long service life. [0004] The technical solution adop...
