Further, described Zola's hook top is provided with the right baffle-plate parallel with left jaw, and described right baffle-plate covers Zola's hook; Described right drag hook top is provided with the right baffle plate parallel with right jaw, and described right baffle plate covers right drag hook.
Further, described left/right clamp handle inner side is connected with flexible arc tooth bar, and described corresponding right/left clamp handle is provided with the hole that tooth bar is passed, and is provided with the gear that can contact with the tooth bar flank of tooth and coordinate in described hole.
Further, in described hole, be provided with tooth bar is pressed in to the spring A on contact site.
Further, between described left and right clamp handle, be connected with spring B.
Further, between described left and right drag hook and corresponding left and right baffle plate, entirety manufacture forms, and is provided with the through hole that can be plugged on left and right jaw in junction.
Further, the limit portion of described left and right drag hook, left baffle and left and right drag hook are all led fillet with the junction of corresponding left baffle.
The beneficial effects of the utility model: jaw type drag hook of the present utility model, comprise the left caliper and the right caliper body that are hinged, described left caliper comprises left clamp handle and is placed in the left jaw of its front end, described right caliper body comprises right clamp handle and is placed in the right jaw of its front end, described left jaw is provided with coupled Zola's hook, described right jaw is provided with coupled right drag hook, left, right drag hook is " eight " font, left and right drag hook is arranged on caliper, can realize the both sides tractive to wound, visual area is openr, and do not need other auxiliary device to be fixed drag hook, drag hook is more stable, can not cause damage to tissue.
Brief description of the drawings
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the structural representation in hole 8.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is elaborated, as shown in the figure: the jaw type drag hook of the present embodiment, comprise the left caliper 1 and the right caliper body 2 that are hinged, described left caliper comprises left clamp handle 101 and is placed in the left jaw 102 of its front end, described right caliper body 2 comprises right clamp handle 201 and is placed in the right jaw 202 of its front end, described left jaw 102 is provided with coupled Zola's hook 3, described right jaw 102 is provided with coupled right drag hook 4, left, right drag hook 3, 4 are " eight " font, left and right drag hook is arranged on caliper, can realize the both sides tractive to wound, visual area is openr, and do not need other auxiliary device to be fixed drag hook, drag hook is more stable, can not cause damage to tissue.
As the further improvement of technique scheme, described Zola's hook 3 tops are provided with the right baffle-plate 5 parallel with left jaw 102, and described right baffle-plate 5 covers the top of Zola's hook 3; Described right drag hook 4 tops are provided with the right baffle plate 6 parallel with right jaw 202, described right baffle plate 6 covers the top of right drag hook 4, and the left and right sides arranges baffle plate and not only can prevent that tissue from emerging but also can avoid drag hook to stretch into tissue and cross dark and tissue is caused to unnecessary damage.
As the further improvement of technique scheme, described left/right clamp handle inner side is connected with flexible arc tooth bar 7, described corresponding right/left clamp handle is provided with the hole 8 that tooth bar is passed, in described hole 8, being provided with the gear 9 that can contact with the tooth bar flank of tooth and coordinate, can accurate adjustment left and right jaw be the distance of left and right drag hook.
As the further improvement of technique scheme, in described hole 8, be provided with tooth bar 7 is pressed in to the spring A10 on gear 9, the distance of left and right jaw is kept to certain.
As the further improvement of technique scheme, between described left and right clamp handle, be connected with spring B 11, further the distance of left and right jaw is kept to certain.
As the further improvement of technique scheme, between described left and right drag hook and corresponding left and right baffle plate, entirety manufacture forms, be provided with the through hole 12,13 that can be plugged on left and right jaw in junction, can be easily by outside drag hook cover and jaw, the interchangeability of drag hook is better.Through hole 12,13 and the left and right jaw part that coordinates with through hole are made as square, can effectively limit rocking of left and right drag hook, wound tractive, fixed effect are better.
As the further improvement of technique scheme, the limit portion of described left and right drag hook, left baffle and left and right drag hook are all led fillet 14 with the junction of corresponding left baffle, prevent that sharpened edge is to tissue injury.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although this utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
