Abstract

The visual puncture sheath capable of being assembled and disassembled in the combined mode comprises a hollow sheath tube and is characterized by further comprising a puncture needle head, a visual assembly and a connecting cable, and the puncture needle head is detachably fixed to the tail end of the sheath tube; the visual assembly is fixed in the puncture needle head; one end of the connecting cable is electrically connected with the visual assembly, and the other end of the connecting cable penetrates through the sheathing canal. During puncture, the puncture needle head is connected with the sheath tube, and the visual assembly can observe the environment at the front end of the puncture sheath, so that the puncture is safer; after puncture is completed, the puncture sheath is pulled out, the puncture needle head is detached, and the sheath tube serves as a guide sheath to establish a channel at the puncture position. Compared with an original structure that a puncture sheath is arranged outside a sheath tube in a sleeving mode, the puncture sheath is only provided with one layer of wall thickness, under the condition of the same outer diameter, the inner diameter of the puncture sheath is increased, the space for containing the visual assembly is enlarged, a module with a larger size can be contained, and clearer images can be obtained.

Description

technical field [0001] The invention relates to the field of puncture sheaths in medical equipment, in particular to a visual puncture sheath that can be assembled and disassembled. Background technique [0002] The puncture sheath is widely used in blood vessel puncture and percutaneous nephrolithotomy. In blood vessel puncture, doctors are constantly trying to find the right blood vessel blindly. In percutaneous nephrolithotomy, the doctor also uses the "blind insertion" method when inserting the puncture sheath, and operates entirely by experience, which is prone to damage the kidney and other organs. In order to overcome the problem of blind insertion and blind detection, a visual component can be set in the puncture sheath, but the visual component will increase the diameter of the puncture sheath, and it is necessary to ensure that the visual component can be installed without increasing the size of the puncture sheath. , the structure of the puncture sheath needs to...
