Abstract
The utility model discloses a disposable tubular hemorrhoid anastomat capable of being automatically located. The anastomat comprises a nail resisting seat, a locating shaft, a driving device, an adjusting screw nut, a nail warehouse and a movable handle, wherein the center of the nail resisting seat is provided with the locating shaft, and the locating shaft is connected with the adjusting screw nut by the driving device; the nail warehouse is connected with the movable handle by the driving device; and the cross section of the locating shaft is semi-circular, and the nail warehouse is provided with a guide hole which is matched with the locating shaft. When the nail resisting seat and the nail warehouse are folded together by the driving device, the semi-circular plane of the locating shaft and a convex rib which is arranged on a peripheral plane can prevent the nail resisting seat and the nail warehouse from relatively rotating, so that the automatic locating of the nail resisting seat and the nail warehouse is guaranteed, and the correct shaping of an anastomosis nail is guaranteed.
Description
Technical field
This utility model relates to medical instruments field, specifically, and the one-shot tube type hemorrhoid anastomat of using in a kind of exactly surgical operation.
Background technology
One-shot tube type hemorrhoid anastomat is applicable to intussusception operation in III °～IV ° hemorrhoid, the mucous membrane of rectum.With respect to traditional hemorrhoidectomy, adopt the hemorrhoid anastomat can shorten operating time, advantage such as have that postoperative damage is little, healing is fast, pain is light, curative effect is high and complication is few.General anastomat can not be located automatically to the position of nail supporting base and nail bin, causes easily the patient to be damaged maloperation.
Summary of the invention
Goal of the invention: this utility model purpose provide a kind of can be with nail supporting base and the automatic localized one-shot tube type hemorrhoid anastomat of nail bin.
In order to solve the problems of the technologies described above, this utility model has adopted following technical scheme: a kind of can automatic localized one-shot tube type hemorrhoid anastomat, comprise nail supporting base, locating shaft, actuating device, adjusting nut, nail bin and flexible handle; The nail supporting base center is provided with locating shaft, and locating shaft is connected with adjusting nut by actuating device; Nail bin is connected with flexible handle by actuating device; The shaft section of described locating shaft is semicircle, and nail bin is provided with the pilot hole suitable with locating shaft.
Wherein, described locating shaft is provided with convex tendon, is provided with the locating slot suitable with convex tendon in the pilot hole, and convex tendon is arranged on the plane of locating shaft periphery.
Beneficial effect: the shaft section of locating shaft of the present utility model is semicircle, on the plane of locating shaft periphery, convex tendon is set, the pilot hole and the locating shaft of nail bin are suitable, also be provided with the locating slot suitable in the pilot hole with convex tendon, in the process that actuating device closes up nail supporting base and nail bin, the automatic location of nail supporting base and nail bin has been guaranteed on the semicircle plane of locating shaft and be arranged on that convex tendon can prevent that nail supporting base and nail bin from producing relative rotation on the semi-circle plane, guarantees the correct molding of anastomosis staple.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing among Fig. 1.
Fig. 3 be among Fig. 1 A-A to cutaway view.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is done further explanation.
Shown in Fig. 1,2 and 3, of the present utility modelly a kind ofly can comprise nail supporting base 1 by automatic localized one-shot tube type hemorrhoid anastomat, nail supporting base 1 center is provided with locating shaft 2, the shaft section of locating shaft 2 is 3/4 semicircle or 4/5 semicircle, be provided with convex tendon 7 on the plane of locating shaft 2 peripheries, convex tendon 7 extends axially along locating shaft 2.Locating shaft 2 is connected with adjusting nut 3 by actuating device, and adjusting nut 3 the place aheads are provided with fixed handle 9; Nail supporting base 1 rear is provided with nail bin 4, and nail bin 4 is connected with flexible handle 5 by actuating device, and nail bin 4 is provided with the large semi-circular pilot hole 6 suitable with locating shaft 2, and the semi-circle plane of pilot hole 6 inwalls is provided with the locating slot 8 suitable with convex tendon 7.
When using this anastomat, hand-held fixed handle 9 also rotates adjusting nut 3, adjusting nut 3 is by 2 motions of actuator drives locating shaft, locating shaft 2 drives nail supporting base 1 and closes up to nail bin 4, because the semi-circle plane of locating shaft 2 and be arranged on that the semi-circle plane and the locating slot 8 of convex tendon 7 and pilot hole 6 cooperatively interacts on the semi-circle plane, nail supporting base 1 and nail bin 5 can not relatively rotate, guaranteed the automatic location of nail supporting base 1 and nail bin 4, nail supporting base 1 is after nail bin 4 closes up, compressing flexible handle 5 is by the anastomosis staple in the actuator drives nail bin 4 and make it molding.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
