Abstract

The utility model discloses a special drag hook for the esophagus. The special drag hook comprises a drag hook rod as well as a pointed-head claw and a flat-head claw that are respectively connected to two ends of the drag hook rod, wherein the two claws are respectively applied to different stages during an esophagus operation; the esophagus is stirred and dissociated through the pointed-head claw at the esophagus dissociation initial stage; when in the dissociation stage, the esophagus is dragged through the flat-head claw, the operation visual field can be fully exposed through the two claws that are used in sequence. The special drag hook for the esophagus has the advantages of reasonable design, and convenience and nicety in use; moreover, the operation quality and the efficiency are improved remarkably, and particularly in the endoscopy minimal invasive surgery, the operating difficulty of surgeons is reduced obviously.

Description

The esophagus drag hook

Technical field

This utility model relates to a kind of surgical operating instrument, relates in particular to the special-purpose drag hook of esophagus.

Technical background

Perform the operation at esophagus, particularly in the thoracoscope micro-wound surgical operation, need earlier blood capillary around the esophagus and hetero-organization thereof to be carried out minute observation, dissect, just can carry out accurately, careful operation, to reduce unnecessary or fatal pair damage, but there is not the special-purpose drag hook of esophagus at present, normally put in and pinion esophagus and then its pull-up is observed by operating on otch with a strap, because strap is flexible and opaque, it is single force direction, can not effectively stir esophagus and observe its back side tissue, and cloth self can block a part of visual field, need exchange repeatedly in the practical operation, rotate strap, so operating difficulties not only in this way, complexity is observed not thoroughly.

Therefore need a kind of reasonable in design, use accurately the special-purpose drag hook of esophagus easily, so that the doctor carries out abundant, careful observation and processing to esophagus, thus high accuracy, high standard and finish operation process expeditiously.

The utility model content

In view of this, this utility model provides a kind of reasonable in design, has used accurately the drag hook of esophagus special use easily, can stir esophagus, dissociate and draw so that observe and carry out subsequent procedures and operate in the esophagus operation.

Tip hook and tack hook that esophagus drag hook of the present utility model comprises the drag hook bar and is separately positioned on drag hook bar two ends.

Further, the tip hook of described esophagus drag hook and tack hook comprise hook body and hook head respectively;

Further, the hook body of described esophagus drag hook and the length ratio of hook head are 3: 1, and successively to a lateral buckling of separately drag hook bar, form hook formation;

Further, the hook head of the tip hook of described esophagus drag hook is in the shape of the letter V, and the hook head of tack hook is rectangular;

Further, to get drag hook bar, tip hook and tack hook be the integral body that the rigidity bar material by an even thickness is bent into to described esophagus drag hook.

This utility model has been filled up the blank of the special-purpose drag hook of esophagus in the surgical operation, its beneficial effect that reaches is: in the esophagus operation process, use accurate and practical, convenient and swift, can effectively expose surgical field of view, significantly improve operation quality and efficient, thereby the shortening operating time reduces patient's pain, reduces surgeon's operation easier.

Description of drawings

Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:

Fig. 1 is an esophagus drag hook axonometric chart.

Fig. 2 is that the A of Fig. 1 is to view.

The specific embodiment

Referring to Fig. 1 Fig. 2, Fig. 1 is an axonometric chart of the present utility model, Fig. 2 be the A of Fig. 1 to view, as shown in the figure: this utility model comprises drag hook bar 2, tip hook 1 and tack hook 3, tip hook 1 comprises hook body 11 and hook head 12, is fixedly connected on an end of drag hook bar 2 by hook body 11; Tack hook 3 comprises hook body 31 and hook head 32, is fixedly connected on the other end of drag hook bar 2 by hook body 31.

In order to satisfy its specific instructions for use of esophagus drag hook,

hook body

11,31 that this utility model is set and

corresponding hook head

12,32 length ratios are 3: 1, and successively to a lateral buckling of drag hook bar 2, make drag hook bar 2 and plane included angle,

hook head

12,32 place less than 90 °, form hook formation, the hook head 12 of tip hook 1 is the V font, and it has unique tip configuration, is used for esophagus is stirred, dissociated; The hook head 32 of tack hook 3 is orthogonal, and its front end is more roomy, and sphere of action is wide, lift effectively, be used for the esophagus pull-up with free state, whole esophagus drag hook is bent into by the rigidity bar material of an even thickness, its compact conformation, it is little to block field range, easy to use, flexible.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, 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 make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
