Abstract

The utility model discloses stretching pliers for neurosurgery, which comprise plier handles and plier arms. The plier handles and plier arms are connected together by the aid of a pin; a stretching claw is fixedly connected to the front end of each plier arm; the tail ends of the plier handles are bent into retractors; a brake mechanism is arranged in the middles of the plier handles and includes a ratchet bar; one plier handle is further provided with a clamp groove meshed with the ratchet bar; jaws can be fixed at different openness by the clamp groove; and a crank is connected onto the clamp groove. By the aid of the stretching pliers for neurosurgery, a user is capable of precisely positioning the stretching claws or the retractors according to actual situations, the working strength of medical staff is decreased, smooth surgeries are ensured, surgical therapy is easy, surgical safety is improved, and surgical time is reduced.

Description

The neurosurgery pulling clamp

Technical field

This utility model relates to a kind of medical apparatus and instruments.

Background technology

Clinically at present, surgical operation is more and more advocated little otch Wicresoftization, under the prerequisite of successful cure diseases, reduce the surgical injury of normal structure as far as possible, alleviate patient's misery, the medical expense etc. of saving patient has become vast surgical operation institute pursue objective, especially art under some Wicresofts of neurosurgery, generally need nerve root be pulled to a side with nerve root retractor, select little otch, must fully expose the art open country, need the assistant to select for use rational drag hook to help the doctor in the operation process, otherwise otch is enlarged, increase the damage of operation, delay the post-operative recovery time, especially too much use common little drag hook, not only need more assistants, both waste of manpower resources have expended operating time, and what also be not easy to perform the operation carries out.

The utility model content

Technical problem to be solved in the utility model provides a kind of neurosurgery when carrying out Minimally Invasive Surgery, and otch is little, and healing is fast, the neurosurgery pulling clamp that operating time is short.

For solving the problems of the technologies described above, the technical solution of the utility model is: the neurosurgery pulling clamp, comprise pincers handle and tong arm, described pincers handle and tong arm link together by bearing pin, described tong arm leading section is fixedly connected with the tractive pawl, the end of described pincers handle is bent to form drag hook, described pincers handle middle-end is provided with arrestment mechanism, described arrestment mechanism comprises ratchet bar, also be provided with the draw-in groove that is meshed with described ratchet bar on the described pincers handle, described draw-in groove can make jaw fix in different folding degree, is connected with crank on the described draw-in groove.

As a kind of optimized technical scheme, described drag hook and described pincers handle at right angles bend.

Owing to adopted technique scheme, the beneficial effects of the utility model are: because the tong arm leading section is fixedly connected with the tractive pawl, the end of described pincers handle is bent to form drag hook, and one-object-many-purposes can well be with all muscle pull-ups; Again because pincers handle middle-end is provided with arrestment mechanism, described arrestment mechanism comprises ratchet bar, also be provided with the draw-in groove that is meshed with described ratchet bar on the described pincers handle, described draw-in groove can make jaw fix in different folding degree, is connected with crank on the described draw-in groove, can make user accurately to locate the position that retracts pawl or drag hook is set according to practical situation, reduce medical worker's working strength, guaranteed carrying out smoothly of operation, be easy to operative treatment, improve the safety of operation, reduce operating time.
