[0024] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example
[0025] This embodiment provides a limiting and retaining device for abdominal paracentesis needles, such as... Figures 1-2 As shown, it includes: a limiting seat 1 and a limiting member 2; wherein the limiting seat 1 has an installation cavity with openings at both ends, and a first needle insertion side opening 11 communicating with the installation cavity on one side; the limiting seat 1 is adapted to fit and fix to the patient's skin; the limiting member 2 is movably installed in the installation cavity, has a limiting cavity with openings at both ends, and a second needle insertion side opening 21 communicating with the limiting cavity on one side; both the first needle insertion side opening 11 and the second needle insertion side opening 21 are adapted for the insertion of the abdominal puncture needle body, and the inner diameter of the limiting cavity is smaller than the outer diameter of the abdominal puncture needle handle.
[0026] When using this device for abdominal paracentesis, first move the limiting member 2 downwards until its top is below the height of the puncture needle handle. Then, place the limiting seat 1 parallel to the puncture needle and move the limiting seat 1 towards the puncture needle so that the needle body passes through the first insertion side opening 11 into the second insertion side opening 21 and into the limiting cavity. After the needle body enters the limiting cavity, fix the limiting seat 1 to the patient's skin. Then, move the limiting member 2 upwards until its top abuts against the puncture needle handle, ensuring that the first insertion side opening 11 and the second insertion side opening 21 are not opposite each other, thereby limiting and fixing the puncture needle. The limiting and holding device for abdominal paracentesis needles in this embodiment can limit and fix the puncture needle, preventing the puncture needle from advancing or deviating during puncture, thus avoiding patient injury and creating favorable conditions for subsequent ascites drainage and drug injection.
[0027] The first needle insertion side opening 11 axially penetrates the limiting seat 1; the second needle insertion side opening 21 axially penetrates the limiting piece 2. Such design can ensure that the puncture needle enters the limiting cavity without any obstacle, and then the puncture needle is limited and fixed by the limiting seat 1 and the limiting piece 2.
[0028] The limiting seat 1 is funnel-shaped, and has a larger surface near the patient, which increases the contact area with the patient's body and improves the overall stability, which is beneficial to subsequent operations.
[0029] The bottom of the limiting seat 1 is fixedly provided with a sticking surface, which is tightly adhered to the patient's body, so that the limiting seat 1 can be stably fixed and will not shake or shift during use.
[0030] The inner wall of the top of the limiting seat 1 is provided with an inner thread, the outer wall of the bottom of the limiting piece 2 is provided with an outer thread, and the limiting piece 2 and the limiting seat 1 are screw-fixed in the mounting cavity. After the puncture needle is placed in the limiting cavity, the limiting seat 1 is fixed, and then the limiting piece 2 is rotated upward, so that the top of the limiting piece 2 abuts against the needle handle of the puncture needle, thereby limiting and fixing the puncture needle.
[0031] The limiting and retaining device for the abdominal puncture needle in the embodiment is used as follows: when used for a patient who needs abdominal puncture, first rotate the limiting piece 2 downward until the top is lower than the height of the needle handle of the puncture needle, then place the limiting seat 1 in a position parallel to the puncture needle, and move the limiting seat 1 towards the puncture needle, so that the needle body of the puncture needle penetrates from the first needle insertion side opening 11 to the second needle insertion side opening 21 and enters the limiting cavity; after the needle body of the puncture needle enters the limiting cavity, fix the limiting seat 1 on the skin of the patient, then rotate the limiting piece 2 upward until the top of the limiting piece 2 abuts against the needle handle of the puncture needle, and the first needle insertion side opening 11 is not opposite to the second needle insertion side opening 21, thereby limiting and fixing the puncture needle.
[0032] Obviously, the above embodiments are only examples for clearly illustrating, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and cannot be exhausted. The changes or variations derived therefrom are still within the protection scope of the technical scheme.
