Puncture needle for urinary surgery

Abstract

The invention relates to the technical field of puncture needles, in particular to a puncture needle for a urinary surgery which comprises a puncture needle body, a scale column is fixedly welded to the upper end of the puncture needle body, scales are arranged on the scale column, an upper top plate is fixedly welded to the upper end of the scale column, and a moving groove is formed in the upper end of the upper top plate. A fixed block is welded and fixed to the front end of the moving groove, two through holes are symmetrically formed in the portions, on the two sides of the fixed block, of the upper top plate, two connecting rods are symmetrically welded and fixed to the fixed block, and the puncture needle is sleeved with an upper limiting ring; the limiting ring can be driven by the lifting plate to move so that the puncture needle can be exposed out of the limiting ring by the corresponding puncture length, the puncture length can be determined according to the scale column above the puncture needle, then the insertion depth of the puncture needle can be accurate by fixing the limiting ring, and the working effect of the puncture needle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of puncture needles, in particular to a urology puncture needle. Background technique [0002] When performing some urological operations, surgical personnel need to use a puncture needle to puncture the abdominal cavity, deliver gas to the abdominal cavity, and establish a channel for the endoscope and surgical instruments to enter and exit the abdominal cavity from the outside, or apply medicine to the lesion through the puncture needle, When performing puncture, it is necessary to accurately measure the depth of puncture to ensure that the puncture needle can accurately enter the working position, while the puncture needles in the prior art are actually used by doctors to independently judge whether the puncture needle is When reaching the working position, the puncture needle has a certain error in the puncture depth. If the depth of the puncture needle is too deep, it is likely to cause injury to the pa...

[0002] When performing some urological operations, surgical personnel need to use a puncture needle to puncture the abdominal cavity, deliver gas to the abdominal cavity, and establish a channel for the endoscope and surgical instruments to enter and exit the abdominal cavity from the outside, or apply medicine to the lesion through the puncture needle, When performing puncture, it is necessary to accurately measure the depth of puncture to ensure that the puncture needle can accurately enter the working position, while the puncture needles in the prior art are actually used by doctors to independently judge whether the puncture needle is When reaching the working position, the puncture needle has a certain error in the puncture depth. If the depth of the puncture needle is too deep, it is likely to cause injury to the patient, and if the depth of the puncture needle is not inserted enough, the puncture needle will have a certain error. not working well
