Embodiment 1

[0033] see Figure 1-Figure 7, the present invention provides a technical solution: a sternal retractor for cardiothoracic and vascular surgery, including a retractor mechanism 1 for retracting the sternum, a lifting translation mechanism 2 for driving the retracting mechanism 1 to lift and translate, and a supporting The supporting mechanism 3 of the lifting and translation mechanism 2, the retracting mechanism 1 includes retracting the slide table 101, a motor one 102, a two-way lead screw 103, a slide block one 104, and a slide bar one 105, and the retracting slide table 101 outer wall is equipped with a motor one 102, the inner side of retracting slide 101 is connected with a bidirectional screw 103 connected to the output shaft of motor 1 102 through bearings, and the outer side of bidirectional screw 103 is threadedly connected with two sliders 104. Both sides of the screw 103 are fixed with a slide bar 105 slidingly connected with the slide block 104, the two-way lead s...

Embodiment 2

[0037] see Figure 8 The difference between Embodiment 2 and Embodiment 1 is that the support mechanism 3 includes a fixed frame 306, a fixed stud 307, a top plate 308, and a rotating handle 309. And be connected with fixed stud 307 by screw thread, fixed stud 307 tops are fixed with rotating handle 309, and fixed stud 307 tops are rotatably connected with top plate 308, sick bed is stuck in fixed frame 306 inner side, utilizes rotating handle 309 to drive fixed stud 307 Rotate, after the fixed stud 307 rotates, it lifts on the fixed frame 306 and then drives the top plate 308 to lift, so that the top plate 308 and the fixed frame 306 are fixed on the sick bed and the position can be changed, and the starting motor three 207 drives the one-way screw two 208 to rotate. Slide block 3 210 is lifted up and down, and then the translation slide table 201 installed on slide block 3 210 is lifted and lowered synchronously, and starting motor 2 202 drives one-way lead screw 1 203 to ro...

Abstract

The invention belongs to the field of sternum retractors, and particularly relates to a sternum retractor for cardiothoracic vascular surgery and a using method of the sternum retractor. The sternum retractor comprises a retraction mechanism for sternum retraction, a lifting and translation mechanism for driving the retraction mechanism to lift and translate and a supporting mechanism for supporting the lifting and translation mechanism. The retraction mechanism comprises a retracting sliding table, a first motor, a bidirectional lead screw, first sliding blocks and first sliding rods, the first motor is installed on the outer wall of the retracting sliding table, the bidirectional lead screw connected with an output shaft of the first motor is connected to the inner side of the retracting sliding table through a bearing, the two first sliding blocks are connected to the outer side of the bidirectional lead screw through threads, and the first sliding rods which are in sliding connection with the first sliding blocks are fixed to the positions, located on the two sides of the bidirectional lead screw, of the inner side of the retracting sliding table. The lifting and translation mechanism is adopted, so that lifting or translation can be carried out by driving the retraction mechanism, the sternum retractor can adapt to the chest position of a patient, and the requirement during sternum retraction is met.

Description

technical field [0001] The invention belongs to the field of sternal retractors, and in particular relates to a sternal retractor for cardiothoracic and vascular surgery and a usage method thereof. Background technique [0002] Cardiothoracic and vascular surgery is a branch of surgery, mainly including heart valve surgery, coronary surgery, great vessel surgery, congenital heart disease surgery and cardiovascular injury surgery. Diagnosis and treatment of diseases mainly include: various valvular diseases; coronary heart disease; congenital or acquired large vessel diseases such as aortic disease and aortic dissection; congenital heart disease; heart tumors and cardiovascular injury and other diseases. Doctors need to perform various cardiovascular surgeries on them. During cardiothoracic surgery, some patients need to cut the skin, subcutaneous tissue, and muscle layer, and enter the chest cavity through a very narrow intercostal space for surgery. Therefore, during the su...
