Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the B-B cross-sectional view of Fig. 1.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, balloon surgical cannula propeller described in the utility model includes sacculus 1, is symmetricly set on sacculus 1
The ingress pipe 2 and delivery line 3 at both ends, the ingress pipe 2 and delivery line 3 are located on same central axes 10, in order to surgical cannula
11 are interspersed in ingress pipe 2 and delivery line 3.Sacculus 1 is made of materials such as soft and flexible silica gel, rubber, is held and is squeezed
It is deformed when pressure, shape can be restored quickly later by unclamping hand.Ingress pipe 2 and delivery line 3 use on-deformable hard material
Material is made, such as stainless steel, duroplasts.Ingress pipe 2 and delivery line 3 are fixedly connected using adhesive with sacculus 1, can also be used
Mold technique is connected as one with sacculus 1.
Mounting disc 4 and guide sleeve 5 are fixedly connected on the inner wall of the sacculus 1, the mounting disc 4 is vertical with central axes
Disk body, the edge of mounting disc 4 is fixedly connected with the inner wall of sacculus 1, at the center of mounting disc 4, positioned at the position of central axes 10
It is provided with through hole, in order to which surgical cannula 11 passes through mounting disc 4, mounting disc 4 is made of hard material, supports ball herein
Capsule inner wall makes sacculus herein will not depressed deformation；The guide sleeve 5 is between delivery line 3 and mounting disc 4, in guide sleeve 5
Sliding sleeve is equipped with the elastic slice 6 of arc, and one end of the elastic slice 6 is fixedly connected in mounting disc 4, the other end is fixedly connected with friction
Piece 7, as shown in Fig. 2, the friction plate 7 is semicircular arc, multiple elastic slices 6 are symmetricly set on the two sides of central axes 10 in pairs,
Corresponding multiple friction plates 7 are symmetricly set on the two sides of central axes 10, to the surgical cannula 11 being located on central axes 10 in surround,
The state of clamping.In use, surgical cannula 11 is inserted into sacculus 1 from ingress pipe 2, the cavity surrounded by multiple friction plates 7
Finally draw from delivery line 3, when needing to push surgical cannula 11 forward, sacculus 1 and squeezed as long as holding, elastic slice 6 by
One end after squeezing with friction plate 7 is drawn close to central axes 10, by the pressing of friction plate 7 in surgical cannula 11, multiple frictions
Piece 7 is clamped in a ring around surgical cannula 11, and surgical cannula can be driven by friction plate 7 by continuing extrusion elastic 6 at this time
11 is mobile to 3 direction of delivery line.It is provided with backstop in the inner cavity of ingress pipe 2, squeezes release hand elastic slice 6 after sacculus 1
When rebound, backstop can block surgical cannula 11, prevent surgical cannula 11 from springing back.
As shown in Figure 1, Figure 3, the backstop include end cap 8, multiple calvus 9 for being connected on end cap 8, the end cap
8 be the circular sheet-like structures that outer diameter is greater than 2 internal diameter of ingress pipe, and positioned at the outer end of ingress pipe 2, the center of end cap 8 has entrance hole
81, multiple calvus 9 are uniformly distributed around entrance hole 81, and the outer end for being parallel to the calvus 9 of the axis setting of ingress pipe 2 is fixedly connected
On end cap 8, inner end pass through ingress pipe 2 extend in the inner cavity of sacculus 1, the calvus 9 for being looped around 81 edge of entrance hole surrounds one
A tubular structure, the internal diameter of the tubular structure is slightly larger than the outer diameter of surgical cannula 11, in order to which surgical cannula 11 can smoothly be worn
It is inserted in the cavity that entrance hole 81 and calvus 9 surround.In the inner wall of sacculus 1 and the joining place of ingress pipe 2 with bell mouth shape
Changeover portion 12, with the convex block 91 for matching the bell mouth shape changeover portion 12, the raised position of convex block 91 is directed toward loudspeaker for the inner end of calvus 9
The changeover portion 12 of mouth shape.When surgical cannula 11 is mobile to 3 direction of delivery line, surgical cannula 11 drives calvus 9 and end
Lid 8 is separated to 1 medial movement of sacculus, convex block 91 with changeover portion 12, and the movement of surgical cannula 11 is unobstructed；Conversely, when operation
When intubation 11 is exited to 2 direction of ingress pipe, surgical cannula 11 drives calvus 9 and end cap 8 to move outward, at this time convex block 91
By the blocking of changeover portion 12, the inner end that changeover portion 12 squeezes calvus 9 makes it be biased to surgical cannula 11, and surgical cannula 11 is embraced
It move it can not, achieve the purpose that non-return.When dismantling surgical cannula 11, as long as pinning end cap 8 makes its holding on the other hand
It is no longer mobile with surgical cannula 11 in interior dead-centre position, calvus 9, smoothly surgical cannula 11 can be extracted out from ingress pipe 2 at this time.
