Embodiment 1

[0018] see Figure 1 to Figure 4 As shown, the retractable retractor device for abdominal surgery includes a retractor 1, a first connecting half ring 2 and a second connecting half ring 3, one of the two ends of the first connecting half ring 2 and the second connecting half ring 3 Part is the insertion end 4, and the other end is respectively provided with slots 5 for insertion of the insertion end 4, and the surface of the slot 5 is provided with a threaded hole 51. The setting of this embodiment is that the first connecting half ring 2 The insertion end 4 is inserted into the slot 5 on the second connection half ring 3, and the insertion end 4 on the second connection half ring 3 is inserted into the slot 5 on the first connection half ring 2, and fastening Bolt 52, the fastening bolt 52 penetrates through the threaded hole 51 and abuts against the surface of the insertion end 4, the first connecting half-ring 2 and the second connecting half-ring 3 respectively pass throu...

Embodiment 2

[0021] Please refer to Figure 5 As shown, the use mode of this embodiment is telescopic mode: when the surgical incision is relatively small, the size of the connecting ring formed by the mutual insertion of the above-mentioned connecting half-rings cannot be well adapted to the area of ​​the surgical incision due to the fixed size. A plurality of adjustment holes 8 are respectively opened on the ring surfaces of the half ring 2 and the second connection half ring 3, and an adjustment bolt 9 is also included, which passes through the adjustment holes 8 to connect the first connection half ring 2 and the second connection half ring 3. Connect up and down to form a connecting ring with an adjustable opening and closing distance. The shape inside the connecting ring is not the circle in Embodiment 1, but a quasi-elliptical shape. The adjustment holes on the half-rings are used to adjust the distance between the two connecting half-rings, so as to reduce the area of ​​the connect...

Abstract

The invention discloses a telescopic dual-purpose drag hook device used for an abdominal operation. The telescopic dual-purpose drag hook device comprises a drag hook, a first connecting half ring and a second connecting half ring, wherein the first connecting half ring and the second connecting half ring are provided with two connecting structures as follows: a first connecting structure is that the end part of one of the two ends of each of the first connecting half ring and the second connecting half ring is an insertion end, the end part of the other end of the two ends of each of the first connecting half ring and the second connecting half ring is provided with an insertion slot for allowing the insertion end to insert, a threaded openings are formed in the surfaces of the insertion slots, the device further comprises fastening bolts which penetrate through the threaded openings and are resisted against the surfaces of the insertion ends, and the first connecting half ring and the second connecting half ring are connected to form a connecting ring with a fixed size through the insertion slots, the insertion ends, and the fastening bolts respectively; a second connecting structure is that a plurality of regulating holes are respectively formed along the ring surfaces of the first connecting half ring and the second connecting half ring, the device further comprises fastening bolts which penetrate through the regulating holes for connecting the first connecting half ring with the second connecting half ring up and down to form a connecting ring with an adjustable opening-closing spacing.

Description

technical field [0001] The invention relates to a surgical device, in particular to a retractor device for the abdominal cavity. Background technique [0002] In the existing clinical abdominal surgery process, it is necessary to fully expose the surgical incision to facilitate the doctor's operation. After the doctor uses the retractor to lift the incision, the incision is pulled apart. At present, the retractor bar is usually supported next to the operating table, and the retractor There is a half-ring shelf on the rod, and then one end of the pull hook is connected to the half-ring shelf, and the other end of the pull rod is used to hook up the cutout. This structure has the following defects: [0003] 1. The pull hook rod needs to be fixed by the nurse under the stage. On the one hand, it increases the manpower. On the other hand, the length of the pull hook rod is too long to cause shaking. At the same time, the nurse may touch the aseptic on the operating table during ...
