Abstract

The invention discloses an in-plane free-angle puncture guiding device capable of being used for probes of various brands, and belongs to the technical field of probe auxiliary medical instruments. The in-plane free-angle puncture guiding device comprises a fixing device, a longitudinal fixing arm, a longitudinal movable arm, a retaining device, a puncture plane device, an installing circular hole, a second side surface and a puncture plane. The fixing device comprises a transverse shaft. One end of the longitudinal fixing arm is arranged at a first end of the transverse shaft, and a first presser foot is arranged at the other end of the longitudinal fixing arm. One end of the longitudinal movable arm is arranged on a second end side of the transverse shaft, and a second presser foot is arranged at the other end of the longitudinal movable arm. The retaining device and the longitudinal movable arm are welded into a whole. The puncture plane device is arranged between the longitudinal fixing arm and the longitudinal movable arm on the transverse shaft and comprises a first side surface. The puncture plane is vertically arranged on the first side surface and the axis of the installing circular hole and penetrates through the second side surface. According to the in-plane free-angle puncture guiding device capable of being used for the probes of various brands, the retaining device has the performance of only advancing but not retreating, so that the fixation is accurate; and the puncture plane device can move and rotate along the transverse shaft, so that the universality ishigh, the in-plane free-angle puncture guiding device can be used for puncture at free angles in planes of the probes of various brands with different thicknesses and different expansion angles, and is flexible to disassemble and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of probe-assisted medical devices, and in particular relates to an in-plane free-angle puncture guide device that can be used for probes of various brands. Background technique [0002] Ultrasound-guided puncture is widely used in various clinical disciplines. It is divided into in-plane and out-of-plane puncture. Relying on the practical experience of the puncture physician, because the deviation of the puncture angle is likely to cause damage to important structures other than the puncture target, such as larger arteries, etc., the puncture guided by the in-plane ultrasonic guiding device greatly improves the puncture accuracy and shortens the time. The learning curve for ultrasound-guided puncture. [0003] In-plane ultrasonic puncture guides are further divided into fixed-angle puncture guides and free-angle puncture guides. The puncture angle of the fixed-angle ultrasonic puncture guide device is fixe...
