5 results about "Insertion angle" patented technology

An inserter assembly that has a base, a needle, an inner part that selectively transitions the needle from a retracted position substantially within the base to an extended position where at least a portion of the needle extends outside of the base, and an insertion angle component. As the inner part of the inserter assembly transitions from the retracted position to the extended position, the needle is at least partially deflected by the insertion angle component.

Several needle insertion devices are disclosed, including devices that achieve a fixed or variable insertion angle. 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 a 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 associate an insertion angle with an insertion depth. Improvements to these designs are also disclosed.

An ultrasonic puncture needle positioning device, belonging to the field of puncture needle positioning technology, addresses the significant uncertainties and errors inherent in manually adjusting the insertion angle and speed of the puncture needle, as well as the inability to slightly move the ultrasonic probe to probe the periphery of the puncture needle during the puncture process. The invention includes an ultrasonic probe, a positioning frame mounted on the probe, an annular plate fixedly mounted on the positioning frame, a moving mechanism mounted on the annular plate, an adjustment mechanism fixedly mounted on the moving mechanism, a needle insertion mechanism fixedly mounted at the end of the adjustment mechanism away from the moving mechanism, several clamping mechanisms fixedly mounted inside the needle insertion mechanism, a rotating mechanism mounted on the needle insertion mechanism, and several suction mechanisms mounted inside the annular plate. This invention not only avoids the uncertainties and errors of manual puncture but also facilitates observation of the puncture needle's state, reducing the probability of secondary injury to the patient.

One medical device may include an alignment portion configured to align the medical device with a spine of a patient. the alignment portion including a first end and a second end. The medical device may also include an insertion portion extending outward from the alignment portion and coupled to the alignment portion at the first end of the alignment portion. where the alignment portion and the insertion portion form an insertion angle. and where the insertion portion includes a set of needle insertion tubes, wherein each needle insertion tube is configured to receive a needle and guide the needle into the patient based on the insertion angle.
