This utility model relates to a kind of operating theater instruments, especially a kind of anus operation on rectum drag hook apparatus.

At present, some operation need operative doctors of anus and rectum stand between patient's two lower limbs and carry out, and need the assistant draw back anus with " L " type drag hook, and the assistant does not have the standing place, and operative site also can not get well appearing.

The purpose of this utility model is to design and a kind ofly can overcomes above defective, need not the assistant and makes operative site appear good anus operation on rectum self-retractor.

The purpose of this utility model is achieved through the following technical solutions: a kind of anus operation on rectum self-retractor, contain hook, its special character is also to be provided with taking position of hollow, hook can by lock mother be fixed on take position on, hook is " L " type hook of middle band slip elongated slot, inner buckle, hook can outwards reach in the 90 ° of scopes in both sides along the slip elongated slot and slide to draw back operative site, then by locking female with hook tighten be fixed on take position on.

Take position and to be set to the disk in the center of circle or with the square plate of the square heart.

In order to make operative site show that fully hook should evenly be established 2 to 8, preferably evenly establishes 4.

Be fixed on field of operation when making the operation of whole drag hook, four circular holes evenly are set on taking position, can drag hook be fixed on field of operation with cloth.

According to the different long different needs of hooks that need of the pathological changes depth, " L " type hook can be changed into inside and outside end all buckle "

" the type hook, the hook of inside and outside end hook is long different, carries out tuning during use as required and gets final product.

In order to make hook can fully hold operative site when working, the termination of hook should be outward-dipping.

The drag hook of this utility model design can be appeared operative site under the assistant's situation that defaults, and the anus operation on rectum is implemented, simple and direct practicality.And hook part can evenly be set operative site is fully appeared, appropriately the fixing operation drag hook can rationally be changed the hook two ends at the different needs of the pathological changes depth at field of operation, can stablize the pulling operative site.

Accompanying drawing and drawing explanation:

Fig. 1 is this utility model most preferred embodiment vertical view;

Fig. 2 is the side view of hook 2.

Among the figure: 1 takes position, 2 hooks, and 3 lockings are female, 4 slip elongated slots, 5 hooks, 6 circular holes, 7 terminations.

Provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying of the present utility model practicing.

With reference to figure 1, Fig. 2.Take position and 1 adopt the disk in the band center of circle, be provided with 4 equally distributed circular holes 6 on it, hook 2 for middle have slip elongated slot 4, the equal buckle 5 in interior outer end "

" the type hook, the hook of inside and outside end hook 5 is long, and one is long and the other is short, and according to circumstances the two ends interchangeable is used; the termination 7 of hook 5 should outwards omit and be tilted get final product; hook 2 can evenly be provided with 4, is fixed on by locking female 4 and takes position on 1, takes position 1, hook 2 and lock mother 3 and all adopt rustless steel to be made.During use, the interior end hook 5 of four hooks is all moved to the center of taking position, hook 5 inserts anuses, draws back hook to four direction respectively, and is female fixing by locking then, thereby operative site is fully appeared.The simple and direct practicality of this utility model.
