Abstract

Disclosed is an automatic pull hook device for rectum cancer operation, belonging to the technical field of medical apparatus. At present, before a rectum cancer operation operates, a uterus and appurtenances are sewn on the abdominal skin by medical threads, which results in bleeding because of the tear of the sewing point; while intestinal canals are pulled upward by a metal pull hook after bundling by gauze pads, which often results in the phenomenon that the intestinal canals drill out from the side of the pull hook. The upper end of a draw deploying rod 1 with a nut 6 is hinged with the upper end of a draw deploying rod 2 with a nut 5 via a rotary shaft 4; a lead screw 8 with a rotary wheel 7 is in a threaded connection mode with the nut 6 and the nut 5; the lower end of the draw deploying rod 1 is fixedly connected with a lower leaf 9; the lower end of the draw deploying rod 2 is fixedly connected to an upper leaf 10 provided with a slide way 11; a soft sheet 12 is connected to a fixing screw 3 arranged inside the slide way 11; a soft sheet 13 is connected to the fixing screw 3 arranged inside the slide way 11. The utility model has the advantage that the automatic pull hook device makes the operation convenient, reduces the operation wound and shortens the operation time.

Description

Rectal cancer surgery self-retractor device

Technical field: this utility model relates to technical field of medical instruments, is rectal cancer surgery self-retractor device more specifically.

Background technology: rectal cancer is the commonly encountered diseases frequently-occurring disease, most row operative treatments that need, but because the rectal cancer surgery process is mainly operated in pelvic cavity, and pelvic cavity is narrow and small, and internal organs such as intestinal tube, uterus, ovary, bladder are more, operating field appears comparatively difficulty.At present the method that adopts is: with uterus and adnexa thereof with the medical wire sutured in abdominal skin because pulling force is bigger, causes suture to be torn sometimes and cause the generation of hemorrhage and postoperative intestinal adhesion; Intestinal tube then wraps up the back with gauze pad and pulls to the top with a metal drag hook, because parcel is imperfect, often occurs intestinal tube in the operation process and gets out pelvic cavity and influence operation technique from the drag hook side, causes operating time to prolong and operation inconvenience.

Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of rectal cancer surgery of design self-retractor device.Its technical scheme is: band nut 6 retract bar 1 upper end and band nut 5 to retract bar 2 upper ends hinged by rotating shaft 4, leading screw 8 and the nut 6 and 5 of band runner 7 are by being threaded, retract the fixedly connected inferior lobe 9 in bar 1 lower end, retract the last leaf 10 of the fixedly connected band chute 11 in bar 2 lower ends, soft thin slice 12 is connected with fixed screw 3 in the chute 11, and soft thin slice 13 is connected with fixed screw 3 in the chute 11.The advantage of this utility model is: the reasonable in design practicality, and novel ingenious, use this device to carry out rectal cancer surgery and overcome above-mentioned shortcoming, make operation technique convenient, reduce operation wound, shorten operating time.

Description of drawings: Fig. 1 front view, the view of Fig. 2, the view of Fig. 3 for making progress at Figure 1B for making progress at Figure 1A.In the accompanying drawing: 1, retract bar, 2, retract bar, 3, fixed screw, 4, rotating shaft, 5, nut, 6, nut, 7, runner, 8, leading screw, 9, inferior lobe, 10, go up leaf, 11, chute, 12, soft thin slice, 13, soft thin slice.

The specific embodiment: band nut 6 retract bar 1 upper end and band nut 5 to retract bar 2 upper ends hinged by rotating shaft 4, leading screw 8 and the nut 6 and 5 of band runner 7 are by being threaded, retract the fixedly connected inferior lobe 9 in bar 1 lower end, retract the last leaf 10 of the fixedly connected band chute 11 in bar 2 lower ends, soft thin slice 12 is connected with fixed screw 3 in the chute 11, soft thin slice 13 is connected with fixed screw 3 in the chute 11: when carrying out rectal cancer surgery, earlier this device is arranged on place, patient abdominal cavity, rotating wheel 7 makes and retracts bar 1 and 2 and open, retract inferior lobe 9 on the bar 1 with uterus and accessory structure pull-up, above the soft thin slice 12 and 13 that last leaf 10 connects by fixed screw 3 (this thin slice 12 and 13 can be inwardly outer flexible along chute) pulls to intestinal tube steadily, abdominal cavity and pelvic cavity are separated fully, fully appear operating field, carry out smoothly with convenient operation.
