Abstract
The utility model discloses a retractor for a general surgical operation, which comprises two elastic retractor arms of which end parts are fixedly connected with each other; a retractor is respectively installed at the other ends of the two retractor arms; at least two pairs of mounting holes are correspondingly formed on the two retractor arms; a compression spring is arranged between the two retractor arms; two end parts of the compression spring are installed in a pair of corresponding mounting holes on the two retractor arms respectively; and limit blocks are detachably installed at the two end parts of the compression spring. The compression spring is installed in different mounting holes through the retractor arms connected in virtue of the compression spring respectively, the distance between the two elastic retractor arms can be adjusted, and the purpose of indirectly adjusting the distance between the two retractors is achieved; therefore, the visual field of the surgical incision is adjusted, no manual traction and fixation is required during the retraction of the surgical incision, the labor intensity of surgeons is reduced, and the retractor for the general surgical operation has a simple structure and is convenient to use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of surgery tractor of using in department of general surgery's operation that is applicable to.
Background technology
In some department of general surgery's operation, because muscle is more, need utilize utensils such as drag hook that patient's operative incision is drawn back during operation, otherwise elasticity of muscle can make operative incision be closed trend, stops doctor's surgical field of view, and what be unfavorable for performing the operation successfully carries out fast, and traditional surgery tractor is to need the long tractive muscle of assistant, after the overlong time, the phenomenon that arm turns sour will appear in the assistant, is unfavorable for alleviating their labor intensity.
The utility model content
Technical problem to be solved in the utility model provides department of general surgery's surgery tractor a kind of easy to use, simple in structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: department of general surgery's surgery tractor, comprise two elastic draw hook arms that the end is fixedly connected, the other end of described two drag hook arms is separately installed with drag hook, article two, correspondence is provided with at least two pairs of installing holes on the described drag hook arm, article two, be provided with the compression spring between the described drag hook arm, the both ends of described compression spring are installed in respectively in a pair of installing hole corresponding on two described drag hook arms, and the both ends of described compression spring detachably are equipped with stop block.
As to improvement of the technical scheme, described drag hook arm is set to rigid plastics structure or rigidity structure.
Owing to adopted technique scheme, department of general surgery's surgery tractor, comprise two elastic draw hook arms that the end is fixedly connected, the other end of described two drag hook arms is separately installed with drag hook, article two, correspondence is provided with at least two pairs of installing holes on the described drag hook arm, article two, be provided with the compression spring between the described drag hook arm, the both ends of described compression spring are installed in respectively in a pair of installing hole corresponding on two described drag hook arms, and the both ends of described compression spring detachably are equipped with stop block; The beneficial effects of the utility model are: the drag hook arm that utilizes the compression spring to connect, the compression spring is installed in the different installing holes, can regulate two distances between the elastic draw hook arm, reach the purpose of distance between two drag hooks of indirect adjustment, thereby regulate the size in the operative incision visual field, when carrying out the tractive operative incision, do not need artificial tractive to fix, reduced the labor intensity of surgical staff, simple in structure, easy to use.
Description of drawings
Accompanying drawing is the structural representation of this utility model embodiment;
Among the figure: 1-drag hook arm; The 2-drag hook; The 3-installing hole; 4-compresses spring.
The specific embodiment
As shown in drawings, department of general surgery's surgery tractor, comprise two elastic draw hook arms 1 that the end is fixedly connected, article two, drag hook arm 1 connection that takes the shape of the letter U, described drag hook arm 1 is set to the rigid plastics structure or uses rigid material to make, between two drag hook arms 1 bigger elastic force is arranged, make two drag hook arms 1 be trend separately all the time; The other end of described two drag hook arms 1 is separately installed with drag hook 2, and drag hook 2 is used for muscle is separated, and to enlarge doctor's surgical field of view, what help to perform the operation carries out smoothly; Article two, correspondence is provided with and is provided with compression spring 4 at least between 3, two described drag hook arms 1 of two pairs of installing holes on the described drag hook arm 1, and the both ends of described compression spring 4 are installed in respectively in a pair of installing hole 3 corresponding on two described drag hook arms 1.
The both ends of described compression spring 4 detachably are equipped with stop block 5, can prevent to compress spring 4 and produce break-off, and can make two ultimate ranges between the drag hook arm 1 obtain restriction.
During use, be installed in the installing holes 3 different on two drag hook arms 1, just can reach the purpose of distance between two drag hooks 2 of indirect adjustment, thereby regulate the size in the operative incision visual field as long as will compress spring 4.This utility model does not need artificial tractive to fix when carrying out the tractive operative incision, has reduced the labor intensity of surgical staff.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in the foregoing description and the description just illustrates principle of the present utility model; under the prerequisite that does not break away from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall in claimed this utility model scope.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
