Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] see figure 1 , a medical puncture expansion implantation tool, comprising a puncture inner needle 1, a puncture expansion part 2, an expansion inner tube 3, an expansion inner tube handle 4, an expansion outer tube 5, an expansion outer tube handle 6 and a puncture needle arranged from inside to outside Inner needle handle 7, wherein,

[0029] The puncture inner needle 1 is a long and thin needle-shaped solid metal material, and one end is a pointed monoclinic knife surface, and the angle of the knife surface is not greater than 45°;

[0030] The puncture expansion part 2 is radially detachable and has a cylindrical shape with a central through hole. The puncture inner needle 1 can pass through the puncture expansion part 2 in the axial direction; one end is hollow cylindrical, and the inner wall of the hollow cylindrical shape is s...

Abstract

The invention discloses a medical puncture, dilation and implantation tool. The medical puncture, dilation and implantation tool comprises an inner puncture needle, a puncture and dilation portion, an inner puncture tube, an inner puncture tube handle, an outer dilation tube, an outer dilation tube handle and an inner puncture needle handle from inside to outside. The inner puncture needle is a long and thin needle made of a solid metal material; the puncture and dilation portion is radically separable, the inner puncture needle is capable of axially penetrating the puncture and dilation portion, one end of the puncture and dilation portion is in a shape of a hollow cylinder, and a locking part is arranged on the inner wall of the puncture and dilation portion; the inner dilation tube is radically separable, the inner puncture needle is capable of axially penetrating the inner dilation tube, a second locking part is arranged at one end of the inner dilation tube, and the outer dilation tube is arranged outside the inner dilation tube; the inner puncture needle handle is connected with the other end of the inner puncture needle. By combination of puncture, dilation and implantation, functional diversity of the tool is realized, operation procedures are simplified, operation time is shortened, puncture times can be reduced, and accordingly puncture pains are relieved for patients. In addition, proper positions are designed for line connection, simplicity in operation is achieved, and great convenience is brought to operations.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a medical puncture expansion implantation tool. Background technique [0002] Existing puncture, expansion, and implantation tools are separated from each other, and each has its own special tool. During use, first puncture with a puncture needle, pull out the inner needle of the puncture needle, then place a guide wire, remove the outer puncture needle, then expand with a dilator, and finally put in the implant that needs to be placed in the body. The process is complicated, has many steps, and lasts for a long time, and first punctures and then expands, which brings secondary puncture pain to the patient. [0003] Moreover, after implantation, some implants need to test their electrical properties or conduct preliminary electrical stimulation tests, so it is necessary to establish a suitable and safe electrical pathway. This all cannot be realized in the prior art. Conten...
