Specific embodiment

Present invention will be further explained below with reference to the attached drawings and examples.

As shown in Figure 1 and Figure 2, the adjustable surgical cannula propeller in direction of the present invention, including determine lever 1, dynamic lever 2, The front end for determining lever 1 is fixedly connected with side plate 3, and the center of the side plate 3 is equipped with ratchet shaft 4, the spine by bearing Return spring 10 is installed, which can use torsional spring as shown in Figure 3, can also use between wheel shaft 4 and side plate 3 Helical spring, effect is can be with self-return after so that ratchet shaft 4 is rotated by a certain angle.The end connection of ratchet shaft 4 is dynamic to hold Handle 2 is set with the ratchet cover plate 5 on ratchet shaft 4, the ratchet machine of single direction rotation is provided between the ratchet cover plate 5 and ratchet shaft 4 Structure can push 5 synchronous rotary of the ratchet cover plate when ratchet shaft 4 rotates clockwise;When ratchet shaft 4 rotates counterclockwise It waits, skids between ratchet shaft 4 and the ratchet cover plate 5, the ratchet cover plate 5 will not rotate with.The concrete form of this ratchet mechanism can have It is a variety of, as shown in fig. 6, the inner periphery in the ratchet cover plate 5 is provided with ratchet, then it is arranged on the excircle of corresponding ratchet shaft 4 There is pawl, which is hinged in the groove of 4 excircle of ratchet shaft, and the ability of return is made it have using torsional spring.Ratchet shaft 4 When rotating clockwise, the front end of pawl is stuck in ratchet, pushes 5 synchronous rotary of the ratchet cover plate;When ratchet shaft 4 rotates counterclockwise, Pawl is depressed on the inclined-plane of ratchet, and ratchet shaft 4 can rotate counterclockwise without restriction.It is of course also possible to which pawl setting is existed On the inner peripheral surface of the ratchet cover plate 5, and ratchet is arranged on the excircle of ratchet shaft 4.

Determining to be provided with tube seat 6 between lever 1 and ratchet shaft 4, the tube seat 6 is arranged at the tangent line of the ratchet cover plate 5.Such as figure Shown in 4, the tube wall of tube seat 6 towards the ratchet cover plate 5 is equipped with notch 61, when tube seat 6 is close to the ratchet cover plate 5, the side of the ratchet cover plate 5 Edge can be put in notch 61, push down the intubation in tube seat 6.With fluted on the excircle of the ratchet cover plate 5, in order to The outer surface of more preferable fitting intubation;In use, intubation 9 is inserted into tube seat 6, the ratchet cover plate 5 is pressed in by the notch on tube seat 6 In intubation 9, when the ratchet cover plate 5 rotates, intubation 9 is pushed to push forward using frictional force.

One end of the tube seat 6, which is installed on, determines on lever 1, and the other end of tube seat 6 is connected to by adjusting screw rod 62 to be held surely On handle 1.

As shown in Figure 4, Figure 5, the tube seat 6 is installed at the nozzle for determining one end on lever 1 with turned-out flanging 63, make it be not easy to fall off from clamping place for determining lever 1.The inside for determining lever 1 is provided with the snap-gauge 11 of mounting hole, tube seat 6 It is inserted into the mounting hole of the snap-gauge 11;The other end of tube seat 6 is fixedly connected with adjusting screw rod 62, and the adjusting screw rod 62 passes through Interspersed be mounted in is determined on lever 1, is equipped with fixture nut 64 by screw thread on adjusting screw rod 62, is provided in the fixture nut 64 Annular slot 65, the upper end for determining lever 1 are fixedly installed with clip 12, and the clip 12 is connected to the annular of fixture nut 64 In card slot 65.When rotary fixing screw mother 64, one end of connection adjusting screw rod 62 is conditioned the drive of screw rod 62 and moves up and down, On the one hand on the other hand the pitch angle of adjustable tube seat 6 can change the distance between tube seat 6 and the ratchet cover plate 5 again, to adjust Save the pressure to intubation.

As shown in Fig. 2, on ratchet shaft 4, being fixedly connected with discoid cover board 7, institute between the ratchet cover plate 5 and dynamic lever 2 State the outside that lever 2 is fixedly connected on cover board 7.The ratchet cover plate 5 is between cover board 7 and side plate 3, plays protection to ratchet mechanism It presss from both sides when acting on, and can be rotated to avoid the ratchet cover plate 5 into foreign matter and causes to seize up.

In operation, it will be intubated in 9 front end insertion tube seat 6, adjusting fixture nut 64 makes between intubation 9 and the ratchet cover plate 5 Frictional force is lucky, and lever 1 and dynamic lever 2 are determined in holding, and constantly pressing can push intubation 9 to advance.
