Abstract
The utility model discloses a kind of orthopaedics dilator, belong to medical instruments field, comprise two parallel connecting rods, described connecting rod is expansion link, described connecting rod is provided with bolt, described connecting rod is fixedly connected with several drag hooks, described two connecting rods are connected to a fixed by two the miniature electric expansion links being connected to its two ends, described miniature electric expansion link is connected with motor switch by electric wire, this utility model structure is simple, easy to operate, just wound can be strutted without the need to medical worker's tractive when bone surgery, expose operative site, expand surgical field of view, alleviate the workload of medical worker, and the fabric width degree strutting wound regulates by electric expansion bar, strut regulating by two telescopic connecting rods from length of wound simultaneously, not easily landing when strutting wound, convenient and practical.
Description
Technical field
This utility model relates to medical instruments field, especially a kind of orthopaedics dilator.
Background technology
At present, drag hook is often used to realize the open of surgical field of view clinically in bone surgery, orthopaedics operation retractor is primarily of the prominent composition of tooth of torque arm, coupler body and coupler body lower end, medical worker exposes surgical field of view with the torque arm of hands tractive, and bone surface ligament, muscle are abundanter, make traction process very painstaking, not only time-consuming but also require great effort, add work difficulty to medical worker, thus cannot ensure the quality of operation, result of use is undesirable.
Summary of the invention
Technical assignment of the present utility model is a kind of orthopaedics dilator provided for above the deficiencies in the prior art.
This utility model solves the technical scheme that its technical problem adopts: a kind of orthopaedics dilator, comprise two parallel connecting rods, described connecting rod is expansion link, described connecting rod is provided with bolt, described connecting rod is fixedly connected with several drag hooks, described two connecting rods are connected to a fixed by two the miniature electric expansion links being connected to its two ends, and described miniature electric expansion link is connected with motor switch by electric wire.
The utility model has the advantage of: 1, this utility model structure is simple, easy to operate; 2, just can strut wound when bone surgery without the need to medical worker's tractive, expose operative site, expand surgical field of view, alleviate the workload of medical worker, time saving and energy saving; 3, length and the equal scalable of width of wound is strutted, convenient and practical; 4, not easily landing when the drag hook that this utility model adopts struts wound, can not increase the misery of patient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described below.
As shown in Figure 1, a kind of orthopaedics dilator, comprise two parallel connecting rods 1, described connecting rod 1 is telescopic rod, described connecting rod 1 is provided with bolt 4, described connecting rod 1 is fixedly connected with several drag hooks 5, and described two connecting rods 1 are connected to a fixed by two the miniature electric expansion links 2 being connected to its two ends, and described miniature electric expansion link 2 is connected with motor switch 3 by electric wire.
Its operation principle is: when making this utility model, first according to the length of wound, connecting rod 1 is elongated to suitable length, then screwed in place bolt 4, fix the length of connecting rod 1, and then drag hook 5 is placed on wound, drag hook 5 is inserted into the depths of wound, the elongation switch of miniature electric expansion link 2 is opened again by motor switch 3, drag hook 5 slowly struts the human body under the drive of miniature electric expansion link 2, when supportting correct position, medical worker turns off the elongation switch of miniature electric expansion link 2, carry out performing the operation, when performing the operation complete, open the retraction switch of miniature electric expansion link 2, drag hook 5 gets back to original position under the drive of miniature electric expansion link 2, then the retraction switch of miniature electric expansion link 2 is turned off, dilator is taken out.
