Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a punching equipment. Background Art

[0002] The punching device is a common device in the mechanical field, which is usually used to drill and punch holes in objects.

[0003] Repairing bone tissue defects has always been an important challenge. Traditional repair methods such as bone transplantation and bone cement filling have various limitations, such as insufficient donors, immune rejection, and slow postoperative recovery. In recent years, with the development of biomaterials and regenerative medicine, bone tissue engineering has become a new research hotspot. However, how to effectively promote the vascularization and osteogenesis of bone tissue is still a problem that needs to be solved. At present, experts prepare specific micropores on the bone tissue to be implanted to provide a suitable growth environment for bone cells and vascular cells, thereby accelerating the regeneration and repair of bone tissue. Therefore, it is necessary to perforate the skull flap.

[0004] The utility model patent with application number: CN201920748382.4 and publication number: CN210228330U (hereinafter referred to as "prior art 1") discloses a skull drilling locator, which relates to the technical field of plastic surgery tools, and comprises a drill bit and a positioning block, wherein the drill bit comprises a drilling portion and a limiting portion, wherein the diameter of the limiting portion is greater than the diameter of the drilling portion; the positioning block is provided with a bottom surface and two pairs of coaxial through holes and limiting holes, wherein the two through holes are obliquely connected to the bottom surface and are not connected to each other. The axes of the two through holes intersect on the side to which the outer normal of the bottom surface points, the aperture of the through hole is smaller than the aperture of the limiting hole but not smaller than the diameter of the drilling portion; the aperture of the limiting hole is consistent with the diameter of the limiting portion, the limiting portion is located at the end of the through hole away from the bottom surface, and a shoulder is arranged between the limiting hole and the through hole; when the limiting portion abuts against the shoulder, the holes drilled from the two through holes to the skull by the drill head are connected to form a "V"-shaped channel that allows the suture needle to pass through; a positioning foot that does not interfere with the drilling portion extending from the through hole is fixed to the bottom surface.

[0005] The specification of prior art 1 discloses a skull drilling locator. When in use, the thread and the rotation direction of the drill bit are consistent.
