Specific implementation mode
The technical solution of this patent is described in more detail With reference to embodiment.
- 2 are please referred to Fig.1, a kind of extending flute needle of ophthalmologic operation, including needle body 1, the needle body 1 are internally provided with cavity
2, cavity 2 is arranged along 1 length direction of needle body, and the upper and lower ends opening of cavity 2, the interior lower end of cavity 2 is equipped with a needle holder 3,
Two sliding slots 4 are symmetrically offered on the interior lower end side wall of cavity 2, are slided in sliding slot 4 and are equipped with sliding block 5, sliding block 5 is located at sliding slot 4
An outer side is fixedly welded on the side wall of needle holder 3, and the lower end of the needle holder 3 offers mounting groove 6, the mounting groove
Syringe needle connecting seat 8 is installed, the lower end of syringe needle connecting seat 8 is equipped with connecting plate 9, and the lower end center of connecting plate 9 is fixedly mounted in 6
There is syringe needle 7, screw rod 10 is additionally provided with inside the cavity 2, the upper end of needle holder 3 offers threaded hole 11, the lower end spiral shell of screw rod 10
Line is arranged in threaded hole 11, and the upper end of screw rod 10 is pierced by the setting of cavity 2, and screw rod 10 is turned by the upper end of bearing 13 and cavity 2
The left side wall of dynamic connection, the needle body 1 offers through-hole 14, and through-hole 14 is connected to cavity 2 and is arranged, and the inside of through-hole 14 is fixedly mounted
There is a thread bush 15, coordinates in thread bush 15 and a trip bolt 16 is installed；In use, by rotating screw rod 10, spiral shell can be made
With needle holder 3 relative motion occurs for bar 10, because the lateral wall of needle holder 3 is limited in by two sliding blocks 5 inside cavity 2
