The specific embodiment

As shown in Figure 1, the crooked drag hook part of now general portable drag hook is larger, is suitable for pullling fixing thicker muscular tissue; In addition, linear hook body part is fit to hold with whole, provides larger strength to pull muscle; These 2 all are unwell to and pull thinner eyelid muscle, and when this drag hook used in the eyelid operation, the medical worker needed careful control dynamics, makes troubles and risk to operation.

Fig. 2 is the isolating construction sketch map of the technical scheme that adopts of this utility model, drag hook 3 and rear drag hook 2 before the rear and front end of hook body 1 respectively has, and there is longitudinally groove 5 separable silica gel hook pad 4 tops, and hook body 1 can embed in the groove 5 of silica gel hook pad 4.

Among Fig. 3, the hook structure that this utility model adopts, its main body hook body 1 is the oblate tapered shape of narrowing toward each end broad in the middle, drag hook 3 and rear drag hook 2 before the rear and front end of hook body 1 respectively has, reclinate front drag hook 3 is used for pullling the muscle of eyelid part, and its curved arc size is fit to the muscle thickness of eyelid part between 3-8mm, when using in the operation, front end can not touch eyeball and cause accidental injury; And rear drag hook 2 its bending directions of hook body 1 rear end are opposite with front drag hook 3 bending directions, and its circular arc size is 18mm-25mm, are fit to catch on its curved arc part with the finger bending, and user mode at this moment as shown in Figure 4.

As shown in Figure 4, the hook body part of this product can be used separately, at this moment the method that adopts finger to catch on rear drag hook 2 curved arc positions is controlled, slight movement by finger, can realize the trickle scope control of pullling, thumb is pressed in the top move left and right of rear drag hook 2, the i.e. angle of fine-tuning drag hook, thereby bring convenience for the eyelid operation that needs meticulous adjusting, also reduced the generation of error.

Fig. 5 and Fig. 6 are silica gel hook pad 4 views of different directions, by wherein visible groove 5 and the aforementioned hook body 1 the same little pyramid type in two broad in the middle that is, its size is slightly less than the mid portion of hook body 1, when reality is used, hook body 1 can be embedded in the groove 5, form such as Fig. 7, the state that is used in combination shown in Figure 8, its role is to, the operation to not needing too large pulling force and repeatedly regulating is inserted into hook body 1 in the middle of the groove 5 of silica gel hook pad 4, formation is used in combination state, after pullling proper range, silica gel hook pad 4 can be parked in skin surface, by the frictional force of silica gel hook pad 4 bottoms and skin surface, get final product fixation hook body 1, thus liberation doctor's both hands.
