8 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.

The invention relates to the technical field of acupuncture and moxibustion, in particular to an acupuncture and moxibustion technique based on layered flat acupuncture, which comprises the following steps: S1, selecting a filiform needle with the specification of 30 * 40 and the needle retaining time of 30 minutes; s2, the palm of the patient faces upwards, the three yin meridian faces are exposed, and the patient is transversely divided into three equal parts from the elbow to the wrist; s3, a circle is drawn at the upper one-third position through drawing, the first needle is located below the circle, the fascia layer is punctured at the angle of 15-30 degrees, and the needle tip enters the direction of the middle finger; s4, the second needle to the third needle perform flat puncturing at the two-thirds position, and the needle points to the index finger direction and the ring finger direction respectively; s5, the fourth to fifth to sixth stitches are located at the lowermost one-third position, and the needle point enters the middle finger, the index finger and the ring finger respectively; s6, inserting the 7th to 8th to 9th needles in the directions that needle tips point to the middle finger, the index finger and the ring finger respectively; the acupuncture and moxibustion device has the beneficial effects that standardized operation is provided, a standardized acupuncture and moxibustion operation process is provided, the needle inserting angle, depth and direction are defined, the operation difficulty is reduced, a beginner can master the acupuncture and moxibustion device conveniently, and popularization of the acupuncture and moxibustion technology is facilitated.

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.

The present invention provides a venous needle insertion training system based on a simulated arm. This system relates to the technical field of venous needle insertion training. The system comprises: constructing a venous needle insertion model based on a standard image of human arm veins; developing replacement blocks for different arm locations in the human arm vein image; monitoring the insertion area, insertion angle, and needle withdrawal distance based on the venous needle insertion model during venous needle insertion training; determining whether the venous needle insertion operation is qualified based on the monitoring results, and retrieving replacement blocks for the same insertion area to update the venous needle insertion model. This system not only meets the need for multiple insertions but also provides real-time feedback on insertion information, thereby improving the efficiency of venous needle insertion training.

The invention belongs to the technical field of medical instruments in the orthopedics department, and particularly relates to a distal tibiofibular screw implantation guider and a using method thereof.When the distal tibiofibular screw implantation guider is used, firstly, data of a fracture part and distal tibiofibular combination are obtained, a corresponding three-dimensional model is established, and simulation reduction operation is conducted on the three-dimensional model. Then, acquiring a cross section image of a specified distance above the ankle joint of the three-dimensional model after restoration, and calculating the implantation angle alpha of the inferior tibiofibular screw according to the image; and then, the forceps body is fixed on the fibula, the angle of the needle tube is adjusted to be alpha, a cortical bone screw is placed after drilling is completed, and finally, the forceps body is taken down, and an incision is sutured. The operation time can be shortened, and the number of times of perspective in the operation is reduced; meanwhile, the implantation angle alpha of the distal tibiofibular screw can be accurately adjusted, operation errors are reduced, and the probability of sequelae caused by deviation of the implantation angle of the screw of a patient is reduced.

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.
