Abstract
The utility model provides a forceps-type traction tool used for neurosurgery, which belongs to the technical field of medical instruments and structurally comprises forceps handles and forceps arms, wherein the forceps handles and the forceps arms are two in number, and are hinged through shaft pins; traction claws are fixed at the ends of the forceps arms through screws; draw hooks are arranged at the rear parts of the forceps handles in a bending way; a rotating toothed bar is arranged between the two forceps handles; a thumb wheel is also arranged on either of the forceps handles and engaged with the rotating toothed bar; and a cranking bar is fixed on the thumb wheel. Compared with the prior art, the forceps-type traction tool used for neurosurgery has the characteristics of reasonable design, simple structure, full function, convenient use and the like; achieves multiple purposes in one tool; and can reduce the workload of the medical staff, ensure smooth surgical operation and reduce the time of the surgical operation.
Description
Technical field
This utility model relates to technical field of medical instruments, a kind of specifically neurosurgery jaw type tractive instrument.
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 some Minimally Invasive Surgerys 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.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of neurosurgery jaw type tractive instrument is provided.
The technical solution of the utility model realizes in the following manner, this neurosurgery jaw type tractive instrument, its structure comprises pincers handle, tong arm, pincers handle, tong arm are provided with two and hinged by pivot pin, described tong arm end is fixed with by screw and retracts pawl, and the rear portion bending of pincers handle is provided with drag hook, is provided with the rotation tooth bar between the described pincers handle, pincers also are provided with on the handle and rotate the thumb wheel that tooth bar is meshed, and are fixed with crank on the thumb wheel.
At right angles bending between described drag hook and the pincers handle.
The beneficial effect that this utility model is compared with prior art produced is:
Neurosurgery of the present utility model has simple in structure with jaw type tractive instrument, reasonable in design, multiple functional, characteristics such as easy to use, both be provided with the pawl that retracts that retracts nerve root on the described tractive instrument, be provided with the drag hook that can fully expose the art open country again, one-object-many-purposes, can well be with all muscle pull-ups, and rotation tooth bar that on the pincers handle, is provided with and the thumb wheel that is meshed, then make user accurately to locate the position that retracts pawl or drag hook is set according to practical situation, reduced medical worker's working strength, guarantee carrying out smoothly of operation, be easy to operative treatment, improve the safety of operation, reduce operating time.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Labelling in the accompanying drawing is represented respectively:
1, retracts pawl, 2, screw, 3, tong arm, 4, the rotation tooth bar, 5, the pincers handle, 6, drag hook, 7, crank, 8, thumb wheel, 9, pivot pin.
The specific embodiment
Below in conjunction with accompanying drawing neurosurgery of the present utility model is done following detailed description the in detail with jaw type tractive instrument.
As shown in Figure 1, this neurosurgery jaw type tractive instrument, its structure by pincers handle 5, tong arm 3, retract pawl 1, drag hook 6 etc. and form, pincers handle 5, tong arm 3 are provided with two and hinged by pivot pin 9, described tong arm 3 ends are fixed with by screw 2 and retract pawl 1, the 5 rear portions bending of pincers handle is provided with drag hook 6, and the angle of bending is the right angle between drag hook 6 and the pincers handle 5.Be provided with rotation tooth bar 4 between the described pincers handle 5, pincers also are provided with on the handle 5 and rotate the thumb wheel 8 that tooth bar 4 is meshed, and are fixed with crank 7 on the thumb wheel 8.
When the medical worker wants neurosurgery of the present utility model used as drag hook 6 with the tractive instrument, only need screw 2 is taken off, take away and retract pawl 1, and tong arm 3 is used the tractive that can undergo surgery as handle, and by rotation crank 7 fixedly thumb wheel 8 get final product with the position that rotates tooth bar 4; When the medical worker wants it is used as retractor, then will retract pawl 1 and be fixed on tong arm 3 ends and can use with screw 2, use is simple and convenient, and can reduce medical worker's working strength, guarantees carrying out smoothly of operation.
