DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0020] Example 1: Refer to Figures 1-5, A surgical retractor fixator, comprising an arc plate 1, the end of the arc plate 1 is fixedly connected to the end of the telescopic rod 14, the telescopic rod 14 is fixedly installed inside the support plate 2, the arc plate 1 and the support plate 2 are in the same plane, and the length direction of the telescopic rod 14 is the same as the length direction of the support plate 2. By activating the telescopic rod 14, the distance between the arc plate 1 and the support plate 2 can be adjusted, and the distance between the arc plates 1 can be adjusted according to the specific needs during the operation. A chute 12 is provided inside the support plate 2, and a second fixing mechanism 13 is slidably arranged inside the chute 12. The position of the second fixing mechanism 13 can be changed by moving along the chute 12. An arc groove 11 is provided inside the arc plate 1, and a first fixing mechanism is slidably arranged inside the arc groove 11. The position of the first fixing mechanism can be changed by moving along the arc groove 11. The first fixing mechanism and the second fixing mechanism 13 have the same structure, and the first fixing mechanism and the second fixing mechanism 13 can support and fix the retractor member 9.
[0021] The first fixing mechanism includes a connecting rod 3. The position of the connecting rod 3 can move inside the arc groove 11. A fastening cover 10 is sleeved on one end of the connecting rod 3 by threads, and a connecting mechanism is fixedly installed on the other end. The upper end of the connecting mechanism is fixedly installed with a retractor member 9 through a bolt. The connecting mechanism is used to connect the retractor member 9 and the connecting rod. By rotating the fastening cover 10, the positions of the connecting rod 3 and the connecting mechanism can be fixed. After the position of the connecting mechanism is fixed, the position of the retractor member 9 can be fixed, and the position of the retractor member 9 can be adjusted according to needs. Moreover, the connection between the connecting rod 3 and the fastening cover 10 is convenient for disassembly and assembly, which can facilitate the disassembly and assembly of the retractor member 9, and the number of retractor members 9 can be adjusted according to needs.
[0022] Working principle: During the use of this surgical retractor fixator, according to needs, the distance between the two arc plates 11 is adjusted through the telescopic rod 14. The arc plate 1 and the support plate 2 are fixed above the surgical position of the patient through the fixing equipment on the operating bed. The connecting rod 3 is placed into the arc groove 11 and the chute 12. After adjusting the position of the retractor member 9 in the arc groove 11 and the chute 12, the position of the retractor member 9 is fixed through the fastening cover 10 and the connecting rod 3. After the retractor member 9 pulls the muscle to adjust the distance, the position of the retractor member 9 is fixed through a bolt. The number of retractor members 9 can be increased according to needs, and the muscles of the patient can be better pulled apart from different directions.
[0023] Embodiment 2: In Embodiment 1, the retractor member 9 is fixedly connected to the connecting rod 3 through the connecting mechanism. Therefore, the angle of the retractor member 9 cannot be adjusted after installation. However, when the retractor member 9 pulls the muscle of the patient, if the position of the retractor member 9 is not convenient to adjust, then the retractor member 9 cannot pull the muscle of the patient from a suitable angle, which will affect the effect of pulling and unfolding the muscle. For this reason, this embodiment is proposed. Refer to Figures 1-4, as another preferred embodiment of the present utility model, based on Embodiment 1, the connecting mechanism includes a fixed disk 4. One side surface of the fixed disk 4 is fixedly connected to the end of the connecting rod 3, and a connecting block 6 is fixedly installed on the other side surface. A rotating disk 5 is rotatably sleeved outside the connecting block 6. A torsion spring 7 is fixedly connected between the outer surface of the connecting block 6 and the inner wall of the rotating disk 5. When the rotating disk 5 rotates around the connecting block 6, the torsion spring 7 provides an elastic resistance. An installation plate 8 is fixedly installed on the surface of the rotating disk 5 away from the fixed disk 4. The inside of the installation plate 8 is fixedly connected to a hook member 9 by bolts. The installation plate 8 is used to support the hook member 9. The connecting rod 3, the fixed disk 4, the rotating disk 5, and the connecting block 6 are coaxially arranged. When the fastening cover 10 is screwed, the connecting rod 3 and the fixed disk 4 are fixed in the arc groove 11. When the hook member 9 pulls the patient's muscle, the hook member 9 can drive the rotating disk 5 to rotate, and the torsion spring 7 is pulled and deformed. By adjusting the angle of the hook member 9, the effect of the hook member 9 pulling the patient's muscle can be improved, so that the affected muscle of the patient can be fully pulled and unfolded.
[0024] Embodiment 3: In the above embodiment, the hook member 9 is a hook in the prior art, and its length and angle are not adjustable. However, during the use of the hook member 9, when the hook member 9 pulls the muscle at the affected part of the patient, due to the limitation of the hook member 9 by the installation plate 8, the height of the hook end of the hook member 9 is fixed, and the hook end of the hook member 9 cannot cooperate well with the patient's muscle. Therefore, this embodiment is proposed. Refer to Figure 1 and Figures 3-5 , as another preferred embodiment of the present utility model, based on Embodiment 1 or Embodiment 2, the hook member 9 includes a fixed rod 91. One end of the fixed rod 91 is fixed in the installation plate 8 by bolts. The position of the fixed rod 91 is limited by the installation plate 8, and the fixed rod 91 can only rotate along the rotating disk 5 to change the angle of the fixed rod 91 in the horizontal direction. An activity groove 95 is opened at the other end of the fixed rod 91. Protrusions 96 are movably clamped on both sides of the activity groove 95. A clamping block 93 is fixedly installed at the end of the protrusion 96. The clamping block 93 is slidably arranged in the activity groove 95 and can rotate around the protrusion 96. The end of the clamping block 93 extends outside the activity groove 95 and is fixedly installed with a hook 92. The hook 92 can rotate around the protrusion 96 through the clamping block 93, and the angle of the hook 92 in the vertical direction can be adjusted. A elastic cord 94 is fixedly connected between the hook 92 and the end of the fixed rod 91. The elastic cord 94 has an elastic connection effect on the fixed rod 91 and the hook 92.
[0025] When the retractor 92 hooks the patient's muscle, the fixing rod 91 is pulled to move outward. The fixing rod 91 and the retractor 92 can rotate around the rotating disc 5. At the same time, the retractor 92 will drive the clamping block 93 to tilt according to the specific position of the patient's muscle. When the clamping block 93 is pulled, it will drive the protrusion 96 to move in the movable groove 95, and the elastic cord 94 is pulled. After the patient's muscle is fully unfolded, the position of the fixing rod 91 is fixed by bolts. The patient's muscle will be pulled more gently by the elastic cord 94. The elastic support of the elastic cord 94 can maintain sufficient pulling force. At the same time, compared with the rigid pulling of a simple retractor, the elastic support of the elastic cord 94 is not likely to cause further damage to the patient's muscle, making it safer.
[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
