Reed will be tensioned（2）With sliding reed（3）It is fixed on sliding block（4）On, the 4th step：Reed will be tensioned（2）Two lower ends installation
In second handle（6）Upside, the 5th step：By sliding reed（3）Two upper ends be mounted on first handle（5）Downside.
It will be oriented to 4 four reed 1, tensioning reed 2, sliding reed 3, saddle components using first handle 5 and second handle 6
It goes along with sb. to guard him among first handle 5 and second handle 6.
Shown in Fig. 1 ~ Figure 10, a kind of four spring structures of surgical instrument, including first handle 5 and second handle 6,
Four leaf spring mechanisms are equipped between two handles, four leaf spring mechanisms include being oriented to reed 1, tensioning reed 2, sliding reed 3 and connecting
The sliding block 4 being connected between tensioning reed 2 and sliding reed 3, four leaf spring mechanisms include being oriented to reed 1, tensioning reed 2, sliding spring
Piece 3, saddle 4 realize the adjusting to sliding block 4 by four leaf spring mechanisms are mounted between first handle 5 and second handle 6,
Tensioning to pull rod 8.
Tensioning reed 2, sliding reed 3 and saddle 4 are in X-shaped, in support and the reply structure of four flat springs.
It will be oriented to reed 1, tensioning reed 2, sliding reed 3, saddle 4 using first handle 5 and second handle 6 and is enclosed in two
Between person, stable building enclosure is formed；Gloves will not be damaged, and tensioning reed 2, sliding reed 3 are set by the way of clamping
It sets in first handle 5 and second handle 6.Reed 2, sliding reed 3 are tensioned in splayed structure, has the effect of tensioning.
The centre position of tensioning reed 2 is fixedly connected with the downside of saddle 4 upwards, and the centre position of sliding reed 3 is downward
It is fixedly connected with the upside of saddle 4, this is fixedly connected with the mode that welding may be used in mode, and bolt can also be used directly fixed
Mode；It is tensioned reed 2, sliding reed 3 during exercise, the gloves of operating personnel will not be damaged.Safety is higher, and utilizes
Splayed can improve the reply intensity of tensioning reed 2, sliding reed 3；Wherein, it is tensioned reed 2, sliding reed 3 uses spring
Piece is made, simple in structure to be easily achieved.
