Problems solved by technology

[0003] Because the volume of the puncture needle is small, it is not easy to pinch it by hand when it is directly placed inside the tray. In order to avoid this phenomenon, the puncture needle is usually placed inside the specially stored sleeve. Shaped and cylindrical sleeves are easy to roll off, and the operating table environment is relatively complicated during the experimental teaching process, which makes it difficult to place the sleeves on the shelf. The spring realizes that the puncture needle is stretched in and out during use, such as US2010100113A1 and CN209004144U, but most of the storage structures for the puncture needle are only left in the closed housing through the needle hole, such as CN110430830A, CN108670336A, so they are not suitable for Experimental teaching application scenarios that need to be taken out and stored repeatedly, and the existing fixtures cannot be uniformly adapted to sleeves of different sizes that accommodate different numbers of puncture needles

Abstract

The invention provides a nerve block puncture needle fixing device under ultrasonic guidance and relates to the technical field of puncture needle placement. The nerve block puncture needle fixing device comprises a clamping device, wherein a box body is sleeved on the surface of the clamping device, the clamping device comprises two sliding rods, and two ends of each sliding rod are respectivelyand fixedly connected with the upper wall and the lower wall in the box body. The sleeve is inserted into the box body along the needle inlet hole; the sleeve enters a circular groove between the adjusting block and the pressing plate through a bearing inner ring; the pressing plate is pressed downwards to slide downwards on the surface of the sliding plate by means of the bearing; the adjusting block is pushed by the pressing plate to slide on the inner bottom wall of the box body; when the pressing plate moves downwards, the angle between the pressing plate and the adjusting block is decreased, the rubber cushion blocks are arranged in the circular grooves to increase the friction force between the circular grooves and the sleeve; since the two circular grooves are larger than one quarter of a circle, the upper wall and the lower wall of the sleeve are clamped during rotation, and therefore the problem that the sleeve is cylindrical and the cylindrical sleeve is prone to rolling offis avoided.

Description

technical field [0001] The invention relates to the technical field of puncture needle placement, in particular to an ultrasound-guided nerve block puncture needle fixing device. Background technique [0002] The puncture needle is a kind of metal needle with a small diameter. The puncture needle is often placed inside the special storage container due to its small self-generated volume. In order to increase the students' ability to use the puncture needle, the teacher often asks the students to hold The puncture needle is operated on the experimental model. Due to the cost of the experimental equipment and the operation on the model, the puncture needle is often used multiple times. [0003] Since the puncture needle is small in size and it is not easy to pinch it by hand when placed directly inside the tray, in order to avoid this phenomenon, the puncture needle is usually placed inside a specially stored sleeve. Shaped and cylindrical sleeves are easy to roll off, and th...
