All parallel to the width direction of the patient's body, the slider 31 is arranged along the width direction of the patient's body, and the two ends of the slider 31 are respectively hinged with the two connecting rods 3, and the sliding direction of the slider 31 relative to the protective cover 1 is parallel to The length direction of the patient's body;

The bottom surface of the protective cover 1 is fixedly formed with a protrusion 16, the screw rod 15 passes through the protrusion 16, and rotates with the protrusion 16, and the axis of the screw rod 15 is parallel to the length direction of the patient's body. The screw rod 15 is threadedly matched with the sliding part 31, and when the screw rod 15 rotates, the sliding part 31 can be driven to move relative to the protective cover 1 along the length direction parallel to the patient's body. When the slider 31 moves, it can drive the connecting rod 3 to rotate around the hinge axis of the first end of the connecting rod 3. With the rotation of the connecting rod 3, the second part of the guiding structure 2 is driven to slide in the sleeve, and the connecting rod 3 The height of the two ends changes, that is, the sliding member 31 can push the protective cover 1 to move upwards, or the protective cover 1 can fall down. It should be noted that, in order to use the screw rod 15 to drive the sliding member 31 to slide, the screw rod 15 can also be rotated and matched with the sliding member 31 and threaded with the protrusion 16 .

A medical rubber layer 43 is attached to the side of the positioning assembly 4 close to the patient's body. The medical rubber layer 43 is also coated with a sponge (in the figure). not shown). The positioning component 4 abuts against the side of the patient's body through the medical rubber layer 43 coated with the sponge. When the patient performs slight movements such as breathing to cause the chest cavity to retract or relax, the medical rubber layer 43 and the sponge can undergo lateral elastic deformation. , to ensure that the positioning component 4 is stable against the patient's body; when the patient's chest rises and falls, the medical rubber layer 43 and the sponge can also undergo longitudinal dislocation deformation, so that the wound protection device moves with the patient's chest rise and fall, ensuring that the plate body 12 and the patient's wound The gauze at the place remains snug.

When this wound protection device is installed on the patient's body, the patient's body is between the two positioning components 4 below the protective cover 1, that is, the open space formed by the bottom surface of the protective cover 1 and the positioning components 4 on both sides is for accommodating the patient. body space.

The process of using the thoracic surgical wound protection device of the present embodiment is as follows:

First make the patient lie flat, adjust the distance between the protective cover 1 and the positioning assembly 4, so that it is close to the positioning assembly 4, and the plate body 12 is pushed by the positioning assembly 4 to slide to cover the opening 11. Then the protective cover 1 is placed above the patient's body, so that the plate body 12 covers the gauze at the patient's wound, and at the same time, the two positioning components 4 are respectively pressed against the patient's body sides, and the wound protection device can be installed on the patient. physically.

When it is necessary to change the dressing for the patient, the threaded mandrel 15 is rotated to drive the protective cover 1 to slide a certain distance away from the patient's body. During this process, the rod body 5 pulls the plate body 12 to slide to expose the opening 11. The medical personnel then replace the gauze and dressing on the patient's wound through the opening 11, and clean up the remaining medicine and blood stains on the patient's body surface. After the above operations are completed, turn the threaded mandrel 15 in the opposite direction to drive the protective cover 1 close to the patient's body until the two plates 12 are combined to cover the opening 11, and at the same time the plate 12 fits the gauze on the patient's wound. Generally, the dressing is changed once every 5-7 days. After changing the dressing three times, the patient's wound is basically healed, and the wound protection device can be removed.

Embodiment two:

Referring to FIG. 4 , the difference between this embodiment and Embodiment 1 is that the positioning assembly 4 includes a body 41 , the body 41 is fixedly connected to the second part of the guide structure 2 , and the connection between the body 41 and the guide structure 2 is realized through the second part of the guide structure 2 . For the connection of the connecting rod 3 and the traction assembly, the two main bodies 41 are respectively located on both sides of the patient's body. The body 41 is provided with two screw rods 411, the screw rods 411 pass through the body 41 and are threadedly engaged with the body 41, the two screw rods 411 are arranged along the length direction of the patient's body, and the axes of the two screw rods 411 are parallel to the patient's body In the width direction, the end of the screw rod 411 close to the patient's body is connected with a positioning piece 42. By screwing in the screw rod 411, the positioning piece 42 can be driven close to the side of the patient's body. When the screw rod 411 is withdrawn, the positioning member 42 can be separated from the side of the patient's body.

In this embodiment, the positioning member 42 is also equipped with a bearing (not shown in the figure), and the screw rod 411 is inserted into the inner hole of the bearing, so that the screw rod 411 and the positioning member 42 are rotatably matched. In order to facilitate the rotation of the screw rod 411 by the medical personnel, a hand wheel is installed at the end of the screw rod 411 away from the positioning member 42 .

Preferably, a medical rubber layer 43 is attached and fixed on the side of the positioning member 42 close to the patient's body, and the medical rubber layer 43 is also covered with a sponge (not shown in the figure). The positioning member 42 is pressed against the side of the patient's body through the medical rubber layer 43 covered with sponge. When the patient performs light movements such as breathing to retract or relax the chest cavity, the medical rubber layer 43 and the sponge can elastically deform laterally. , to ensure that the positioning component 4 is stable against the patient's body; when the patient's chest rises and falls, the medical rubber layer 43 and the sponge can also undergo longitudinal dislocation deformation, so that the wound protection device moves with the patient's chest rise and fall, ensuring that the plate body 12 and the patient's wound The gauze at the place remains snug. In the above process, the lateral or longitudinal deformation of the medical rubber layer 43 and the sponge can be used to reduce the obstruction of the wound protection device to the patient when performing slight movements, and reduce the patient's discomfort when using the wound protection device.

Embodiment three

Referring to Fig. 5, the difference between the present embodiment and the first embodiment is that the traction assembly includes two sections of rod body 5 that are rotatably connected, and the hinged two sections of rod body 5 constitute a two-section rod 6 as a whole, and the two ends of the two-section rod 6 It is hingedly mounted between the guide rod 14 and the second part of the guide structure 2 . The wound protection device is installed on the patient's body, and when the plate body 12 is attached to the gauze at the wound of the patient's body, there is a certain angle between the two sections of the rod body 5, and the hinge point between the two sections of the rod body 5 is located in the two sections. The two ends connecting line of formula bar 6 are close to the side of protective cover 1. When it is necessary to replace dressings and gauze on the patient's wound, the protective cover 1 is controlled to move away from the positioning assembly 4, the two-stage rod 6 is first straightened, and then the plate body 12 is pulled out of the opening 11. During the straightening process of the two-stage rod 6, the plate body 12 is out of contact with the gauze at the patient's wound, and then the straightened two-stage rod 6 pulls the plate body 12 to break away from the opening 11, which can ensure that the plate body 12 and the gauze are separated from the opening 11. The gauze will not be pulled when in contact, so as to prevent the patient's wound from being pulled when the plate body 12 moves, which is beneficial to the recovery of the patient's wound.

It should be noted that after the wound protection device is installed on the patient's body, for the straightened two-section rod 6, in order to avoid the shortening of the distance between the two ends of the two-section rod 6, the hinge point between the two-section rod body 5 will be shortened. Move toward the side connecting the two ends of the two-section rod 6 close to the patient's body, a stopper can be set at the hinged position of the two-section rod body 5 to limit the relative rotation angle range between the two-section rod body 5, and avoid the two-section The hinge point between the rod bodies 5 moves to the side close to the patient's body on the line connecting the two ends of the two-section rod 6 . Elastic parts can also be installed between the two sections of the rod body 5, and the two sections of the rod body 5 can be tightened by using the elastic parts, so that the two sections of the rod body 5 have a rotation trend that meets the demand, and the two sections of the rod body 5 can rotate relatively with this rotation trend, so that the two sections of the rod body can be The hinge point between 5 moves toward the side connecting the two ends of the two-section bar 6 near the protective cover 1.

After the wound protection device is installed on the patient's body, the two-section rod 6 is in a folded state, which can prevent the traction assembly from occupying too much space for the patient's body, so as to accommodate the patient's body, thereby improving the use of the wound protection device by the patient. comfort at the time.

Preferably, the protection device also includes a limiting structure arranged on the bottom surface of the guide rod 14 , and when the protective cover 1 approaches the positioning assembly 4 , the two sections of the rod body 5 first rotate relative to each other. After the rod body 5 hinged with the guide rod 14 rotates until it reaches the limit structure, it can no longer continue to rotate. As the protective cover 1 continues to approach the positioning assembly 4, the rod body 5 hinged with the second part of the guide structure 2 continues to rotate. The formula rod 6 integrally pushes the guide rod 14 and the plate body 12 to slide towards the direction close to the opening 11 , and finally the two plate bodies 12 are combined to cover the opening 11 .

In this embodiment, the position-limiting structure is a bump 141 arranged on the bottom surface of the guide rod 14. In fact, the bottom surface of the guide rod 14 can also be used as a position-limiting structure.
