Specific embodiment
With reference to the accompanying drawing, the present invention is described in detail.
As shown in Figure 1, including the first pincers 101, second pincers handles present embodiment discloses a kind of high-performance flexible obstetric forceps
102, the first pincers are being hinged on the second pincers upper, and the first pincers handle and the second pincers are equipped with uneven structure, with side
Just hold, in some embodiments, the first pincers with the second pincers can also be using the form that is hinged.First pincers handle
101 and second the end of pincers handle be respectively equipped with blade 2, blade is two, the opening and fitting that two blades can separate, when two
The fitting of a blade close to when, fetus head is clamped, and then is favorably given a birth progress.
As shown in Fig. 2, blade and pincers are rotation connection between（As 2 circles indicate part）, when rotation connection is also one
The junction of a blade and pincers handle, can also the junction of two blades and pincers handle be dismountable connection, Fig. 2 is merely illustrated
The previous case.The rotation connection reaches following effect：When the chucking power of blade is less than certain value, this turns function junction not
Mutually rotation, blade and pincers between be it is rigid be fixedly connected, and then can keep giving fetus head enough chucking powers, when
Occur mutually rotation when chucking power is greater than certain force, at the rotation connection, blade relative to pincers being turned out, Jin Erhuan
The chucking power to fetus head is rushed, the effect of protection fetus head is played.In order to reach said effect, in a specific implementation
In example, as shown in figure 3, the end of blade 2 is hinged seat 401, hinged seat is equipped with hinged channel 402, and the second pincers are being stuck in
In hinged channel 402, the part that the second pincers are stuck in hinged channel 102 is equipped with hollow portion 406, is fixedly connected on hinged seat
On the articulated shaft 403 of hollow portion, the both ends fixed hinge axis of articulated shaft and hollow portion 406 is passed through, cooperation can make
Handle must be clamped and blade mutually rotates.
As shown in fig. 7, being the cross section structure of hollow portion, the side of hollow portion is equipped with opposite loose slot 4061, hingedly
Axis is equipped with the movable part 4031 for going deep into loose slot, as shown in Figure 5.As shown in Figure 4 and Figure 6, matching for articulated shaft and hollow portion
Close schematic diagram, each movable part along loose slot around the axial direction activity of articulated shaft, two sides of the second pincers handle and hinged
It is respectively equipped with the first spring 404 and second spring 405 between seat, when movable part is stuck in loose slot, the first spring and the
Two springs are twisting states, state as shown in Figure 4.This when, the twisting resistance of spring are M, movable part 4031 and activity
Extruding force between slot is M（The sum of two）, certain movable part and loose slot can also be equipped with one, at that time can for two
To cause power more to be dispersed, using effect is improved.In pincers being clamped by hand, clamp the driving torque to blade this when
It will further increase, when the power of the rotation between blade is less than M by the second pincers, due between movable part and loose slot
Extruding force can offset this power, keep rotation axis and hollow portion not to occur mutually to rotate, clamping will not between handle and blade
Mutually rotation occurs, remains rigid state.When the further gripper clamp handle of hand, pincers can increase the driving torque between blade
Greatly, until this when, the extruding force between movable part and loose slot can not be offset, loose slot and movable part when being greater than M
Can be gradually disengaged, this separation seems simple, but when clamping, can chucking power effectively between buffering blade, rise
To the effect of buffering, fetus head is protected.When existing, since obstetric forceps is rigid, doctor fear injure fetus will not,
Too big power dare not be used, and then causes chucking power not tight, under use of the invention, doctor can give up this misgivings, can
Improve enough chucking powers.When, in order to adjust this critical force M, can be equipped in the side of loose slot 4061
Layer of silica gel, if it is desired to which critical force is big, can use hard（Coefficient of elasticity is big）Silica gel, if it is desired to critical force is small, can be with
Using soft（Coefficient of elasticity is small）Silica gel, above-mentioned adjusting can be adjusted according to infective use, further increase production
The plasticity of pincers.Meanwhile layer of silica gel can also place blade and pincers sudden surge when turning to maximum, play buffering effect
Fruit.
By adopting the above-described technical solution, can effectively avoid clamping it is excessive the head of fetus is influenced, therefore make
With when, doctor enough can clamp, therefore, be equipped with elastic material for blade outer layer and provide possibility, therefore
In improved embodiment, the outer layer of the blade is equipped with silica gel buffer layer.Can be with layer of silica gel, it is ensured that fetus head and
The contact area of blade reduces the minimally invasive influence on Fetal Brain.
When in use, fixed between articulated shaft both ends and hinged seat, in order to improve the rotation of articulated shaft and hollow portion
Effect, the diameter of hollow portion is typically larger than articulated shaft, but pincers swing possible opposite hinged seat in this way, therefore are improving
Scheme in, set on 402 side of hinged channel there are two coaxial recess portion 407, the section of recess portion is greater than the first spring
Or the section of second spring, bottom of the both ends of articulated shaft respectively with two recess portions connect firmly, the first spring and second spring
It is deep into recess portion in whole or in part.Thus can by the shrinkage in width in hinged channel, until and pincers handle it is of same size,
By pincers the axial rotation of intelligence is limited to, its stability is maintained.
