Detailed Description
Exemplary embodiments of the invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1 to 4, a puncture needle with a blunt tip of the present invention comprises: the outer needle assembly 2 and the inner needle assembly 1 sleeved in the outer needle assembly 2, the outer needle assembly 2 comprises an outer needle base 21 and an outer needle 22 positioned at one end of the outer needle base 21, and the inner needle assembly 1 comprises an inner needle base 11 and an inner needle 12 positioned at one end of the inner needle base 11; the inner needle 12 has a blunt tip 121, and the length of the inner needle 12 is smaller than that of the outer needle 22. The needle point of the inner needle 12 is designed to be a flat head structure, and the length of the inner needle 12 is smaller than that of the outer needle 22, so that the production difficulty of the puncture needle can be reduced, the production efficiency can be improved, and the production cost can be saved.
The protrusion is provided with the hand position 211 that is used for assisting the puncture operation on the outer wall of outer needle file 21 of this application embodiment, and the axis of needle file 21 outside hand position 211 sets up for central symmetry, and the hand position can be two, and radial relative setting along outer needle file 21, this pjncture needle is when using, and operating personnel passes through two hand positions, can with the pjncture needle is firmly held, and convenient operation, the hand position also can be a holistic cake structure, when propelling movement this pjncture needle, can be better bulldoze the application of force, puncture safer, and before preparing puncture hand, because the axis of needle file 21 outside the hand position sets up for central symmetry, consequently can place firmly on the operating table, can not roll easily.
The hand position 211 is of a plate-shaped structure and is perpendicular to the outer needle seat 21, so that the puncture needle can be held by an operator conveniently, the operator is prevented from sliding off in the operation process, and the hand position can be made into a rectangular plate shape, a polygonal plate shape and other shapes according to actual needs or habits of the operator.
