Embodiment Construction

[0045] like figure 1 As shown, the present embodiment is a drilling tool, the drilling tool includes a drill rod 1, the tail end of the drill rod 1 is rotatably mounted on the rod handle 3, and the rod handle 3 is built with a circumferential ring for driving the drill rod 1 to rotate. Driver; the head end of the drill rod 1 is equipped with a drill bit 2, the drill bit 2 and the drill rod 1 are vertically arranged at 90° and the two are reversingly driven by a worm gear pair.

[0046] The drill rod 1 of this embodiment includes a rod body 11 and a rod head 12 that is rotatably connected to the rod body 11 through a universal joint 4, and the drill bit 2 is rotatably mounted on the rod head 12; Variability, when the angle between the rod head 12 and the rod body 11 changes, the working angle of the drill bit 2 also changes; and it can always ensure that the rod head 12 and the rod body 11 rotate synchronously.

[0047] The rod body 11, the universal coupling 4 and the rod hea...

Abstract

The invention discloses a punching tool which comprises a drill rod and a drill bit arranged at the head end of the drill rod, the drill rod comprises a rod body and a rod head rotationally connected with the rod body, and the drill bit is rotationally installed on the rod head; the drill rod is further provided with a steering driving mechanism, and the steering driving mechanism is used for driving the rod head to rotate relative to the rod body so as to adjust the working angle of the drill bit. The drill rod is divided into the rod body and the rod head in a split mode, the steering driving mechanism is further arranged to drive the rod head to rotate relative to the rod body, and due to the fact that the drill bit is arranged on the rod head, when the angle between the rod head and the rod body changes, the angle between the drill bit and the rod body also changes; in this way, the working angle of the drill bit can be adjusted according to needs, and the punching tool is suitable for more rib fracture repair surgeries.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a punching tool. Background technique [0002] Compared with traditional surgical methods, thoracoscopic rib fracture repair surgery has greatly improved, mainly reflected in: [0003] (1) The traditional rib fracture surgery needs to cut from the skin to the pectoralis major or serratus anterior, and then peel off the periosteum and intercostal muscles, which may damage the intercostal nerves, intercostal arteries and veins, and cause secondary damage to the patient during surgical fixation. However, thoracoscopic surgery can be performed from the intrathoracic approach, and the broken end of the rib fracture can be seen more directly, and the reduction and fixation of the rib fracture in the entire thoracic cavity can be completed through an operation hole of about 4 cm. , to avoid damage to muscles, nerves, and blood vessels. [0004] (2) In tradition...
