Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to the little otch drag hook of a kind of novel jaw type.
Background technology
At present, surgical operation is more and more advocated little otch Wicresoftization, under the prerequisite of successful cure diseases, reduces the surgical injury of normal structure, the misery that alleviates patient, the medical expense etc. of saving patient as far as possible and has become numerous surgeon institute pursue objective.The employing of little otch must fully appear the art open country, and assistant's reasonable tractive must be arranged in the art, and fully hemostasis could guarantee carrying out smoothly of small incision surgery, otherwise can only enlarge otch, has increased the damage of operation, has delayed the time of post-operative recovery.Such as tracheotomy, assistant's drag hook tractive continues, and two goitre retractors of assistant not only continue, and also must balance in power.Giving emergency treatment to a patient when making emergency tracheotomy, must race against time, there is not assistant's participation, operation is difficult to carry out smoothly, if can there be a kind of drag hook to continue tractive without the assistant, not only saves time, can also save the human resources, when giving emergency treatment to a patient in addition one man operation also can finish smoothly.In addition, the external undercut of the internal fixation of jaw fracture in the jaw operation on face, the tractive of the swollen thing otch in positions such as neck surface, the tractive of the little otch of other surgical operations etc. all needs the assistance by means of common drag hook and assistant.So the human resources has been wasted in the use of common little drag hook, has expended operating time, what be not easy to perform the operation carries out.
Summary of the invention
For solving above-mentioned deficiency, the purpose of this utility model is to provide a kind of traction wound convenient and practical, simple in structure, has avoided the interference of many handss when making operation, can obviously save operating time, improves the little otch drag hook of novel jaw type of operation efficient.
For achieving the above object, the technical scheme that this utility model adopted is: the little otch drag hook of a kind of novel jaw type, it is by shank, the ratchet joint, beak portion, alar part constitutes, it is characterized in that described shank and ratchet fixed by screw-cap, inboard at shank is provided with spring leaf, and described beak portion and the alar part hook-type that meets at right angles is made the shape of the little drag hook of thyroid with it, be beneficial to and profound deeply retract and stop surrounding tissue, the rear is by the control in pincers shank ratchet joint, drag hook opened and fixing, reaches the purpose that appears the art district.
The beneficial effects of the utility model: the traction wound is convenient and practical, reduced the human resources in the art, avoided the interference of many handss when making operation, effectively improved operation efficient, this utility model is chosen the forceps spreader handle end and is opened freely characteristic, and can magnify to different in width and can fixed advantage, choose the profile that pincers beak end is transformed into the little drag hook hook of thyroid end, the two combines, and makes drag hook open the back and keeps continuing equilibrium state, has made things convenient for the carrying out of operation.
