Abstract

Several needle insertion devices are disclosed, including devices that achieve fixed or variable insertion angles. The fixed insertion angle device may include a channel guide with a stop to limit insertion to a desired depth. The fixed insertion angle device may also include a rack and pinion mechanism to maintain the insertion geometry to achieve the desired depth. The variable insertion angle design may include a channel guide with a stop to limit insertion to a desired depth. The variable insertion angle device may also implement a depth cam configured to correlate the insertion angle with the insertion depth. Improvements to these designs are also disclosed.

The application also relates to PCT application PCT/US2022/036009 entitled "Systems, methods and apparatus for ultrasonic needle positioning devices" filed on 7.1.2022, and U.S. provisional application 63/218191 entitled "Systems, methods, AND DEVICES DIRECTED to Ultrasonic Needle Positioning Apparatus" filed on 2.7.2021. The entire contents of these applications are incorporated herein by reference in their entirety. Technical Field The present application relates to systems, methods, and devices for needle positioning in medical procedures. Background The approaches described in this section are approaches that could be pursued, but not necessarily approaches that were previously conceived or pursued. Thus, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section. Disclosure of Invention Many medical procedures may require the use of needles, catheters, etc. that are inserted into the patient (e.g., vein). However, proper insertion can be difficult, particularly for obese, intravenous drug use, and the like. Failure to insert can lead to frustration and discomfort. Ultrasound imaging may be used to locate an inserted feature (e.g., vein), which may increase the likelihood of successful placement. However, failed attempts may still frequently occur, and some ultrasound-assisted methods may be cumbersome to use, or may provide only partial solutions. For example, for needle insertion, it is important to maintain the stability of the patient, the ultrasound imaging probe, and the needle during insertion. Furthermore, it may be important to insert the needle at an appropriate angle and at an appropriate depth. Drawings The invention may be better understood with reference to the following drawings.
