[0027] Exposure of surgical field is a key issue in surgery. If the surgical exposure position is not good, it will easily affect the doctor's operation. When the current surgical retractor pulls the patient's skin, the top structure of the retractor will be located above the patient's surgical incision, which can easily affect the doctor's surgical field of view and thus affect the progress of the entire operation.

[0028] See also Figure 1-Figure 4 As shown, the device includes a support frame 1, and two extension arms 11 are fixedly connected to the upper side wall of the support frame 1, the bottoms of the two extension arms 11 are connected to the hook assembly 2, the middle part of the hook assembly 2 is connected to an adjustment assembly 3 for adjusting its angle, and the end of the hook assembly 2 away from the support frame 1 is connected to a support assembly 4 for assisting the start of the hook, and the hook assembly 2 includes two extension rods 21 located at the bottom end of the support frame 1, the two extension rods 21 are respectively connected to the bottoms of the two extension arms 11, and the other ends of the two extension rods 21 are movably connected to inclined plates 22, and the surfaces of the two inclined plates 22 on the side away from the extension rods 21 are provided with hook bodies 23, wherein the inclined plates 22 are micro-elastic structures.

[0029] First, the specific structure of the adjustment component 3 is disclosed. The adjustment component 3 includes a plurality of plug-in rods 32 fixedly connected to the end of the inclined plate 22, and the plurality of plug-in rods 32 are all located on the side of the inclined plate 22 away from the retractor body 23. The end of the extension rod 21 is provided with a plug-in hole 33 that fits the surface of the plug-in rod 32. The surface of the side of the extension rod 21 away from the inclined plate 22 is connected with a clamping plate 31, and the clamping plate 31 is sleeved on the surface of the plug-in rod 32. Before the operation begins, the two inclined plates 22 are adjusted to the angle to be used, and then the plurality of plug-in rods 32 fixedly connected to the ends of the inclined plates 22 are inserted into the plug-in holes 33 opened at the ends of the extension rods 21, and then the clamping plate 31 is used to clamp the ends of the plug-in rods 32, so as to improve the stability of the angle adjustment of the inclined plate 22, so that the patient's surgical incision is stably supported without affecting the doctor's field of vision.

[0030] Secondly, the specific structure of the support assembly 4 is disclosed. The support assembly 4 includes a middle rod 41 connected between two extension rods 21. Side rods 43 are fixedly connected to both sides of the middle rod 41. The ends of the two side rods 43 pass through the inclined plate 22 and are connected to the hook body 23. The two side rods 43 are both made of airbags. A connecting tube 42 is fixedly connected to the surface of the middle rod 41. The other end of the connecting tube 42 is connected to a squeezing bag 44. The squeezing bag 44 is fixedly connected to the top of the support frame 1. When the hook body 23 needs to support the surgical incision of the patient, the squeezing bag 44 is pressed so that the air inside the squeezing bag 44 is transported to the inside of the middle rod 41 through the connecting tube 42. By using the side rods 43 as airbags and the middle rod 41 as an elastic hollow structure, the two hook bodies 23 can be extended, which is more convenient for supporting the surgical incision of the patient. When the hook body 23 needs to be retracted, the air vent at the end of the middle rod 41 is opened to shrink the side rods 43.

[0031] The improvement of this embodiment is that: first, the extension arm 11 arranged on the surface of the support frame 1 is used so that the extension rod 21 can be connected to the bottom of the two extension arms 11 respectively, so that the two inclined plates 22 and the two retractor bodies 23 can be installed. Before the operation begins, the two inclined plates 22 are adjusted to the angles to be used, and then the plurality of plug-in rods 32 fixedly connected to the ends of the inclined plates 22 are inserted into the plug-in holes 33 opened at the ends of the extension rods 21, and then the clamping plate 31 is used to clamp the ends of the plug-in rods 32, so as to improve the stability of the angle adjustment of the inclined plates 22, so that the patient's surgical incision is stably supported without affecting the doctor's field of vision;

[0032] When the retractor body 23 needs to support the patient's surgical incision, the squeezing bag 44 is pressed so that the air inside the squeezing bag 44 is transported to the inside of the middle rod 41 through the connecting tube 42. The side rod 43 is made of airbag material and the middle rod 41 is an elastic hollow structure, so the two retractor bodies 23 can be extended to facilitate supporting the patient's surgical incision. When the retractor body 23 needs to be retracted, the air vent at the end of the middle rod 41 is opened to shrink the side rod 43.

[0033] Considering that the retractor body 23 needs to contact with the patient's skin, in order to improve the pulling stability of the retractor body 23, Figure 1-Figure 2 As shown, the inner walls of the two hook bodies 23 are both paved with adsorption pads 5 , and the surfaces of the adsorption pads 5 are made of soft material.

[0034] The improvement lies in that the absorption pad 5 laid on the inner wall of the retractor body 23 can improve the contact stability between the retractor body 23 and the patient's skin, and the absorption pad 5 is made of soft material, which effectively reduces the situation where the retractor body 23 accidentally injures the patient's skin.

[0035] After the angle of the inclined plate 22 is adjusted and fixed, it needs to be reinforced again by the clamping plate 31. Therefore, in order to further improve the clamping and stabilizing effect of the clamping plate 31, Figure 2-Figure 3 As shown, a magnetic reinforcement sheet 6 is laid on one side surface of the chuck 31, and the surfaces of the two extension rods 21 are both made of metal.

[0036] The improvement lies in: using a magnetic reinforcement sheet 6 laid on one side of the chuck 31 and the surface of the extension rod 21 is made of metal, which effectively improves the fitting stability between the chuck 31 and the extension rod 21, thereby improving the fixing effect of the chuck 31 on the inclined plate 22.

[0037] In summary, the working principle of the present invention is as follows: first, the extension arms 11 arranged on the surface of the support frame 1 are used so that the extension rods 21 can be connected to the bottoms of the two extension arms 11 respectively, so that the two inclined plates 22 and the two retractor bodies 23 can be installed. Before the operation begins, the two inclined plates 22 are adjusted to the angles to be used, and then the plurality of plug-in rods 32 fixedly connected to the ends of the inclined plates 22 are inserted into the plug-in holes 33 opened at the ends of the extension rods 21, and then the clamping plate 31 is used to clamp the ends of the plug-in rods 32, so as to improve the stability of the angle adjustment of the inclined plates 22. The function is to stably support the surgical incision of the patient without affecting the doctor's field of vision. The magnetic reinforcement sheet 6 laid on one side of the chuck 31 and the surface of the extension rod 21 are made of metal, which effectively improves the fitting stability between the chuck 31 and the extension rod 21, thereby improving the fixing effect of the chuck 31 on the inclined plate 22. The adsorption pad 5 laid on the inner wall of the retractor body 23 can improve the contact stability between the retractor body 23 and the patient's skin. The adsorption pad 5 is made of soft material, which effectively reduces the possibility of the retractor body 23 accidentally injuring the patient's skin.

[0038] When the retractor body 23 needs to support the patient's surgical incision, the squeezing bag 44 is pressed so that the air inside the squeezing bag 44 is transported to the inside of the middle rod 41 through the connecting tube 42. The side rod 43 is made of airbag material and the middle rod 41 is an elastic hollow structure, so the two retractor bodies 23 can be extended to facilitate supporting the patient's surgical incision. When the retractor body 23 needs to be retracted, the air vent at the end of the middle rod 41 is opened to shrink the side rod 43.
