[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0022] Example:

[0023] like Figures 1 to 4As shown, the utility model provides a retractor, including a connecting seat 1, two groups of movable rods 4 are arranged at the front end of the connecting seat 1, and the rear ends of the two groups of movable rods 4 are both provided with a first connecting block 3, a first sliding groove 2 is opened at the front end of the connecting seat 1, and the two groups of first connecting blocks 3 are both clamped in the first sliding groove 2, two groups of traction blocks 7 are arranged at the front ends of the two groups of movable rods 4, and the tops of the two groups of traction blocks 7 are both provided with fixed blocks 6, and the front ends of the two groups of movable rods 4 are both provided with clamping grooves 5, and the two groups of fixed blocks 6 are respectively clamped in the two groups of clamping grooves 5. When using the retractor, the doctor can clamp the traction block 7 clamped at one end of the two groups of movable rods 4 on the patient's chest cavity, and then pull it. At this time, the two groups of movable rods 4 will move to both ends, thereby retracting the patient's chest cavity. Such a structure can provide stable traction and keep it in the required position, and it is not easy to move or slide, thereby ensuring the stability of the surgical operation. Since the traction block 7 is separated from the connecting seat 1 by a certain distance, when the doctor uses the retractor, after opening the chest cavity, such a structure can also effectively expand the surgical field of view. It enables doctors to better observe and operate the target area, improves the accuracy and safety of the operation, and effectively reduces postoperative complications and adverse reactions. Second connecting blocks 8 are clamped at both ends of the connecting seat 1, and a threaded rod 9 is inserted into one group of the second connecting blocks 8. One end of the threaded rod 9 passes through two groups of first connecting blocks 3 and is clamped on the inner side surface of one end of the connecting seat 1. A first knob 10 is provided on one side of one group of the second connecting blocks 8, and the other end of the threaded rod 9 is clamped in the first knob 10. A protrusion 11 is provided on the first knob 10. When the retractor is in use, after the doctor fixes its traction block 7 on the patient's chest cavity, the doctor can rotate the first knob 10 through the protrusion 11 to adjust and control its traction force, so that it can move the two groups of movable rods 4 to their two ends to produce a traction effect, and after being pulled to the appropriate position, the threaded rod 9 can fix the two groups of movable rods 4 to keep them in the desired position, so that they are not easy to move or slide, thereby ensuring the stability of the surgical operation.

[0024] like Figures 2 to 4As shown, a fixing seat 15 is provided under the two groups of second connecting blocks 8, a first support rod 12 is provided on the top of the two groups of fixing seats 15, a second support rod 13 is provided at the bottom of the two groups of second connecting blocks 8, the two groups of second support rods 13 are respectively clamped in the two groups of first support rods 12, a second knob 17 is provided on one side of the two groups of first support rods 12, a fixing hole 18 is provided on one side of the two groups of second support rods 13, a second slide groove 14 is provided on one side of the two groups of first support rods 12, one end of the two groups of second knobs 17 passes through the two groups of second slide grooves 14 respectively, and is clamped in the two groups of fixing holes 18. This structure enables the retractor to adapt to the body shape differences and surgical needs of different patients. When using the retractor, the doctor can flexibly adjust the second support rod 1 according to the specific situation. 3, so as to achieve better separation and fixation effect, so as to help doctors better separate and fix the chest wall, and also better disperse the pressure and reduce the discomfort to patients. This structure makes the retractor suitable for different patients. The bottom of the two groups of first support rods 12 are provided with a fixing seat 15, the bottom of the two groups of fixing seats 15 are provided with a second knob 17, the two groups of fixing seats 15 are provided with a splint 16, one end of the two groups of second knobs 17 respectively passes through the bottom of the two groups of fixing seats 15, and is clamped at the bottom of the two groups of splints 16. After the doctor inserts the two groups of fixing seats 15 into both sides of the operating table, he can rotate the second knob 17 to make the splint 16 and the fixing seat 15 form a mutual force, so as to fix the retractor on the operating table.

[0025] The specific usage and function of this embodiment are as follows:

[0026] The traction block 7 provided on the retractor is separated from the connecting seat 1 by a certain distance. When the doctor uses the retractor, such a structure will prevent the retractor from affecting the doctor's surgical operation range, allowing the doctor to better observe, evaluate and handle the surgical area, improve the accuracy and success rate of the surgery, and the structure can more evenly apply force to the chest cavity to open the chest cavity, thereby reducing damage to the tissue. The retractor is also provided with an adjustable fixing bracket, which enables the retractor to adapt to the body shape differences and surgical needs of different patients. The doctor can flexibly adjust the height of the bracket according to the specific situation to achieve a better separation and fixation effect, thereby helping the doctor to better separate and fix the chest wall, and also better disperse the pressure and reduce the discomfort of the patient. This structure makes the retractor suitable for different patients.
