Problems solved by technology

[0003] When the existing sternum fixation device for cardiac surgery supports the sternum, it directly shifts the sternum and the upper epidermis to both sides. At this time, the skin and muscles in between will be torn to both sides, resulting in an excessively large opening. The field of view required during the operation is relatively fixed. Excessively large tear openings will increase the time-consuming suturing in the later stage, and will also delay the healing and later recovery of the patient, and it is also not conducive to the post-healing process. It is beautiful, so people hope that the surgical wound should be as small as possible, but the existing fixation device can easily cause the wound to tear and enlarge the wound. Therefore, we propose a sternum fixation device for heart surgery

Embodiment 1

[0031] see Figure 1-Figure 6 , a sternum fixation device for cardiac surgery in the figure, including a driving device 4, a clamping device 5, a pulling device 6 and two groups of support rods 1, the two groups of support rods 1 are fixedly connected with a device box 2, and the device box 2 is fixedly connected with a support plate 3 for supporting and fixing the sternum. The driving device 4 is installed on the supporting rod 1 to drive the two groups of supporting rods 1 to slide and open to both sides to complete the supporting and fixing of the sternum. The clamping device 5 is installed At both ends of the device box 2, it is used to clamp and fix the muscles and skins at both ends of the patient's chest opening during the initial stage of the support plate 3 sliding to both sides. 3. When the sternum is continuously stretched to both sides, the linkage rotates and pulls the clamping device 5 inward to a certain extent, thereby reducing the tearing force on both sides of ...

Embodiment 2

[0036] see Figure 7-Figure 9 and Figure 12 The second embodiment will be described. The present embodiment will further describe the first embodiment. The clamping device 5 in the figure includes two sets of clockwork shafts 17 connected to the device slot 15. The clockwork shaft 17 is connected with the device slot 15. The rotating block 18 is rotatably connected, the rotating block 18 is fixedly connected with a device block 19, a lifting groove 20 is opened in the device block 19, and a first clamping block 21 and a second clamping block 22 are slidably connected in the lifting groove 20. The bottoms of the second clamping blocks 22 are fixedly connected with a plurality of plug pins 51 , the first clamping block 21 is fixedly connected with a first rack 23 slidably connected with the lifting groove 20 , and the second clamping block 22 is fixedly connected with The second rack 24 is slidably connected with the lifting slot 20. The lifting slot 20 is rotatably connected ...

Embodiment 3

[0041] see Figure 10-Figure 12 The third embodiment will be described. This embodiment will further describe the first embodiment. The pulling device 6 in the figure includes a plurality of second tooth blocks 39 , a driving slot 40 is formed in the rotating block 18 , and a plurality of second tooth blocks 39 , etc. The distance is distributed and is slidably connected with the driving slot 40. The driving slot 40 is slidably connected with a lifting plate 41 that is fixedly connected to the second clamping block 22, and the second tooth block 39 is provided with a slope 42 that is slidingly connected to the lifting plate 41. The device slot 15 is provided with a rotating member 43 for interlocking the rotating block 18 to rotate when the second toothed block 39 slides out of the driving slot 40 .

[0042] see Figure 10-Figure 12 , the rotating member 43 in the figure includes a second belt 44, a first rotating shaft 45 and a second rotating shaft 46 are rotatably connecte...

Abstract

The invention discloses a sternum fixing device for a cardiac surgery, relates to the field of sternum fixing for the cardiac surgery, and solves the problem that a wound is continuously torn excessively due to the fact that a sternum and skin muscles are directly supported towards two sides when an existing sternum fixing device for the cardiac surgery is used. Comprising a driving device, a clamping device, a pulling device and two sets of supporting rods, the two sets of supporting rods are fixedly connected with device boxes, and the device boxes are fixedly connected with supporting plates used for supporting and fixing the sternum. The device is simple in structure and convenient to use, skin muscles on the two sides are conveniently clamped and fixed in the initial stage of supporting, and the clamping devices on the two sides are driven to be slowly closed towards the middle along with continuous opening and linkage operation of the pulling device, so that the tearing force of a skin opening towards the two sides is reduced, a wound is reduced, and rapid suturing and wound healing in the later period are facilitated.

Description

technical field [0001] The invention relates to the technical field of sternum fixation in cardiac surgery, in particular to a sternum fixing device for cardiac surgery. Background technique [0002] Since Gebin performed the first open heart surgery under cardiopulmonary bypass in 1956, cardiac surgeons have routinely used a median chest incision. Although surgeons have tried various surgical approaches for cardiac surgery, it is still generally believed that the median thoracic incision is the safest and best exposed approach in cardiac surgery. The median chest incision requires longitudinal splitting of the sternum to expose tissues such as the heart and blood vessels for surgery. After the sternum is split, a sternum fixation device is required to pull or push the longitudinally severed sternum to both sides to expand the cardiac field of view and facilitate the operation. conduct. [0003] When the existing sternum fixation device for cardiac surgery is used for ster...
