Detailed description of the invention
Describe illustrative, the non-limiting example of the present invention with reference to the accompanying drawings in detail, to the chain type according to the present invention
Blocking-up pincers are further described.
With reference to Fig. 1-3, disclosing a kind of chain type and block pincers in one exemplary embodiment of the present invention, this chain type blocks pincers
Including fixed handle 2, flexible handle 1, lengthening handle 4, fixed pliers head 51, movable binding clip 52 and solid mild steel rope 41.Fixing hands
Handle 2 and flexible handle 1 are connected respectively to one end of lengthening handle 4, the other end of lengthening handle 4 respectively with fixed pliers head 51 and adjustable clamp
52 are connected, and flexible handle 1 is by being connected through the solid mild steel rope 41 of lengthening handle 4 with movable binding clip 52.
Flexible handle 1 is connected with fixed handle 2, and flexible handle 1 can be relative to fixed handle 2 folding, so
Operator can control fixed pliers head 51 and the folding of activity binding clip 52 by flexible handle 1 and fixed handle 2.Lengthen
Handle 4 is that hollow structure is so that solid mild steel rope 41 passes in lengthening handle 4.Further, one end of lengthening handle 4 respectively with fixed handle
2 are connected with flexible handle 1.Lengthening handle 4 can bend, and such operator can block according to the position of otch and needs
The position of blood vessel carries out free bend and sizing to this lengthening handle 4, thus reduces otch quantity and size to greatest extent.Fixing
Binding clip 51 is connected with the other end of lengthening handle 4, and movable binding clip 52 is connected with fixed pliers head 51, and movable binding clip 52 passes through
Solid mild steel rope 41 is connected with flexible handle 1, in order to operator control fixation clamps by flexible handle 1 and fixed handle 2
51 and the folding of movable binding clip 52.In one embodiment of the invention, solid mild steel rope 41 is by hinge and movable binding clip
52 are connected.
When operator use this chain type to block pincers blocking-up blood vessel, according to the position of the blood vessel that incision site and needs block
Free bend lengthening handle 4 of shaping, then control fixed pliers head 51 and movable binding clip 52 by flexible handle 1 and fixed handle 2
Folding to block blood vessel.As shown in the above description, chain type disclosed by the invention blocking-up pincers are simple to operate, it is simple to operator's root
The shape blocking pincers is adjusted, to realize reducing otch quantity and size, quickening patient's postsurgical recovery according to different surgery situation
Purpose.
With reference to Fig. 3, in one embodiment of the invention, the lengthening handle 4 of this chain type blocking-up pincers includes hollow bowden cable 42
With multiple tube couplings 43.
Hollow bowden cable 42 has through hole along its length, and solid mild steel rope 41 is held through the part of lengthening handle 4
It is contained in the through hole of hollow bowden cable 42.Flexible handle 1 is relative with fixed handle 2 when opening or close, and flexible handle 1 pulls reality
Soft-hearted cable wire 41, solid mild steel rope 41 can slide in hollow bowden cable 42, such that it is able to further pull on fixed pliers head 51
Open with movable binding clip 52 or close.Multiple tube couplings 43 are arranged along the length direction of hollow bowden cable 42, and multiple tube coupling 43
In each arrange around hollow bowden cable 42.Hollow bowden cable 42 can tighten up and loosen.When hollow bowden cable 42 tightens up
Time, the adjacent tube coupling in multiple tube couplings 43 is pressed against each other and produces frictional force, and pressure and frictional force that this compression produces make phase
The position relationship of adjacent tube coupling is relatively fixed, so that the shape of lengthening handle 4 is fixed up；When hollow bowden cable 42 loosens, many
Adjacent tube coupling in individual tube coupling 43 loosens each other, i.e. adjacent tubes internode is not in contact with, and will not produce frictional force, so that lengthening
Handle 4 can be with free bend.Therefore, after surgical incision site and vessel position determine, operator i.e. may determine therefrom that required
Chain type block pincers bending direction and crooked radian；After bending direction and crooked radian determine, loosen hollow bowden cable 42, with
Make the lengthening handle 4 can be with free bend；Lengthening handle 4 is adjusted to required bending direction and crooked radian；After adjustment, tighten up
Hollow bowden cable 42, so that adjacent tube coupling is pressed against each other and produces pressure and frictional force, thus fixes the shape of lengthening handle 4.By
Described above is it is recognised that the bending of lengthening handle disclosed by the invention 4 and method for shaping are simple, it is easy to operator's operation process
Middle operation.
With continued reference to Fig. 3, in one embodiment of the invention, lengthening handle 4 also includes cable wire set 44.Cable wire set 44 setting
In hollow bowden cable 42, and cable wire set 44 has center through hole in its longitudinal direction, and solid mild steel rope 41 is through lengthening
The part of handle 4 be arranged on cable wire set 44 center through hole in and can cable wire set 44 in slidably.It is permissible that cable wire overlaps 44
The slip of protection solid mild steel rope 41 is more smooth and easy.
With reference to Fig. 2 and 4, in one embodiment of the invention, this chain type blocks to clamp and also includes body 7, sizing knob 3 and
Contiguous block 6.
One end of body 7 is connected with described one end of lengthening handle 4, the other end respectively with fixed handle 2 and flexible handle 1
It is connected.Sizing knob 3 is arranged around body 7, and knob 3 of shaping can slide by rotating the length direction along body 7
(as shown in Figure 4, sizing knob 3 can horizontally slip along body 7).Contiguous block 6 is arranged in body 7, and contiguous block 6 has
The dop 61 of radial protrusion, dop 61 can be connected to shape in knob 3, so that contiguous block 6 is along with the slip of sizing knob 3
And along the length direction slip of body 7.Further, contiguous block 6 is towards one end and the hollow bowden cable of hollow bowden cable 42
42 are connected.In one embodiment, hollow bowden cable 42 is welded and fixed with contiguous block 6.So, when sizing knob 3 is along pipe
When body 7 horizontally slips, sizing is selected drives contiguous block 6 to horizontally slip, contiguous block 6 be further driven to hollow bowden cable 42 tighten up or
Loosen.It is connected with flexible handle 1 it addition, solid mild steel rope 41 is each passed through body 7 with contiguous block 6.
With reference to Fig. 4, in one embodiment of the invention, each in multiple tube couplings 43 is annular, and this annular
One end face be cambered surface, another end face be the conical surface, the cambered surface of each and the conical surface in multiple tube couplings 43 are respectively facing its phase
The conical surface of adjacent tube coupling and cambered surface.So, when hollow bowden cable 42 tightens up, the conical surface to coordinating, increases contact area with cambered surface.
The method using chain type disclosed by the invention blocking-up pincers blocking-up blood vessel in operation process is as follows: work as surgical incision site
After determining with vessel position, operator i.e. may determine therefrom that required chain type blocks bending direction and the crooked radian of pincers；Curved
After Qu Fangxiang and crooked radian determine, sizing knob 3 (as shown in Figures 2 and 4) that turns left is to loosen hollow bowden cable 42, adjacent
Tube coupling 43 between be not in contact with (as shown in Figure 4, be not in contact with between tube coupling 431 and tube coupling 432), lengthening handle 4 can be free
Bending；Lengthening handle 4 is adjusted to required bending direction and crooked radian；After adjustment completes, to right rotation sizing knob 3 (as
Shown in Fig. 2 and 4) to tighten up hollow bowden cable 42, adjacent tube coupling is pressed against each other and produces pressure and frictional force, thus fixes and lengthen
The shape of handle 4.
Although the exemplary embodiments of the present invention is illustrated, but it is clear that it will be understood by those skilled in the art that
Can be changed without departing substantially from the case of spirit and principles of the present invention, its scope is in claims and its equivalent
It is defined.
