Description

Technical Field

[0001] This utility model relates to the field of electronic circuit opener technology, specifically to an electronic circuit opener. Background Technology

[0002] A conventional electronic stent system mainly consists of a metal probe rod, an injection-molded handle, a circuit board assembly (including a battery and speaker), and supporting instruments. It primarily identifies the direction and location of the screw path based on the impedance value of the metal probe tip against the internal tissue. This allows for rapid and accurate screw placement without the need for large fluoroscopic equipment.

[0003] Existing electronic circuit openers typically use T-shaped or spherical handles. T-shaped handles require constant hand switching to achieve rotation, resulting in limited flexibility. Spherical handles generally have poor grip and a smooth surface, leading to insufficient torque during rotation. Furthermore, existing electronic circuit opener switches are mostly pull-tab type, which carries the risk of breakage and becomes slippery when stained with oil or blood, lacking tactile feedback. Fallen pull tabs are also easily lost, posing a surgical risk. Additionally, the handle cannot be struck, limiting the surgical procedure. Moreover, the handle body and end cap are often glued together, which can easily introduce non-biocompatible substances. Utility Model Content
