Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-5, a trocar that leakproofness is antibacterial high, including sleeve pipe 1, needle handle 2 and long needle 3, its characterized in that, sleeve pipe 1 top is equipped with needle handle 2, first thread groove 4 is seted up to 2 bottoms of needle handle, sleeve pipe 1 interpolation is equipped with

long needle

3, 3 tops of long needle are equipped with first screw thread 5, long needle 3 is through

first screw thread

5 and 4 threaded connection of first thread groove, second thread groove 12 has been seted up to sleeve pipe 1 bottom, 2 bottoms of needle handle are inlayed and are equipped with silica gel sealing ring 8, annular 7 that corresponds with silica gel sealing ring 8 is seted up to the bottom in second thread groove 12,

sleeve pipe

1 and 2 top surfaces of needle handle all are equipped with first anti-skidding 10 lines.

The top of the needle handle 2 is provided with a second anti-skid grain 9, and the second anti-skid grain 9 is positioned at the bottom of the first thread 5.

In this embodiment, as shown in fig. 1, the first thread 5 on the long needle 3 is convenient for a person to be in threaded connection with the first thread groove 4 on the needle handle 2, and the second anti-skid thread 9 can improve the anti-skid effect of the twisting and dismounting of the needle handle 2.

Wherein, silica gel sealing ring 8 and sleeve pipe 1 surface all cover and have photocatalyst antibacterial material layer 11.

In this embodiment, as shown in fig. 1, 3 and 5, the use of the silicone sealing ring 8 and the photocatalyst bacteriostatic material layer 11 on the surface of the sleeve 1 can improve the sanitation of the use of the whole trocar.
