Specific implementation mode

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in Figure 1, a kind of hepatic surgery used saccular dilation guide tube comprising sleeve 1, a gas tube 2 and one infusion Pipe 3.

In Fig. 1, it is equipped with sacculus 4 on casing 1, several raised 5 are equipped in the outer surface of sacculus 4.

As shown in Figure 1, gas tube 2, woven hose 3 are wrapped in casing 1, and pass through sacculus 4, in corresponding sacculus 4 Ten ventholes 6 are offered on the tube wall of gas tube 2.

In Fig. 1, one end of gas tube 2 is concordant with one end of casing 1, and one leakage of connection on one end of gas tube 2 Bucket-shaped groove 7.

As shown in Figure 1, opening up a through-hole 8 in funnel-shaped recesses makes 7, one end of woven hose 3 is connected with through-hole 8, infusion The one end of pipe 3 far from through-hole 8 extends to the outside of casing 1.

In Fig. 1, the one end of gas tube 2 far from funnel-shaped recesses makes 7 extends to the outside of casing 1, and remote in gas tube 2 A gas cell 9 is connected on one end from funnel-shaped recesses makes 7.

In Fig. 1, an air inlet pipe 10 is connected on the gas tube 2 close to gas cell 9, on gas tube 2 and air inlet pipe 10 Equipped with a control valve 11.

It should be further noted that as shown in Fig. 2, control valve 11 includes a bottom frame 111, an activity box 113 and one control Bar 112 processed, control-rod 112 is laterally movable to be applied in bottom frame 111, and activity box 113 is fixedly connected on the control-rod in bottom frame 111 On 112；A groove 1111 is opened up in the middle part of the bottom of bottom frame 111, a fixture block 115 is movably equipped in groove 1111, in fixture block One first spring 114 is connected between 115 and the slot bottom of groove 1111, fixture block 115 contacts with activity box 113 and positions activity box 113。
