[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figure 1-4 As shown, the wound fixation device for postoperative rehabilitation of thoracic surgery provided in this embodiment includes a front shell 1, a tightening mechanism 2 and a winding component 3.

[0029] See also Figure 1-Figure 4The front shell 1 is used to be placed on the patient's chest, and has through holes 11 on both sides thereof and a middle seam 12 on the rear side thereof. Specifically, the middle seam 12 is in the shape of a narrow vertical strip.

[0030] like Figure 3 and Figure 4 As shown, the tightening mechanism 2 is installed inside the front housing 1, and includes two rotating shafts 21, two transmission structures 22 and two control wires 23. The two rotating shafts 21 are axially rotatably installed inside the front housing 1 and are respectively located on both sides of the middle seam 12. A gear 211 is provided at the end of each rotating shaft 21, and the two transmission structures 22 are respectively connected to the gears 211 on the two rotating shafts 21 and are slidably installed inside the front housing 1. A control wire 23 is provided on each transmission structure 22, one end of each control wire 23 is connected to the transmission structure 22, and the other end movably passes through the adjacent through hole 11 and is provided with an arm ring 231, which is used to be placed on the patient's upper arm. The transmission structure 22 is pulled by the control wire 23, which drives the rotating shaft 21 to rotate.

[0031] Specifically, gears 211 are provided at both ends of each rotating shaft 21 to improve transmission stability. The transmission structure 22 includes two racks 221 and a connecting plate 222. The two racks 221 are respectively provided at both ends of the connecting plate 222. Each rack 221 is respectively connected to the corresponding gear 211 in transmission and slidably connected to the inner wall of the front housing 1. The connecting plate 222 is connected to the control wire 23. When the patient's arm moves, the control wire 23 is pulled by the arm ring 231 on the arm, thereby driving the transmission structure 22 to move as a whole, and then driving the rotating shaft 21 to rotate axially through the rack 221 and the gear 211.

[0032] Of course, in order to adapt to patients with different arm circumferences and improve the patient's use experience, preferably, the arm ring 231 has different sizes, and the arm ring 231 is detachably connected to the control wire 23, wherein any one of the methods such as snap connection and sleeve connection can be selected for detachable connection. Furthermore, in order to adapt to patients of different body shapes, an adjustment buckle is provided on the control wire 23 to adjust the length of the control wire 23, and the adjustment buckle can be selected from existing technical products sold on the market, and the adjustment buckle can be set at the position where the control wire 23 is located outside the front shell 1.

[0033] See also Figure 1-Figure 4The winding assembly 3 includes an external fixing belt 31 and a tightening belt 32. The two ends of the external fixing belt 31 are respectively connected to the two sides of the front shell 1. The tightening belt 32 is located on the inner side of the external fixing belt 31, and the two ends of the tightening belt 32 flexibly pass through the middle seam 12 and are respectively fixedly connected to the two rotating shafts 21. It is worth noting that both the external fixing belt 31 and the tightening belt 32 are elastic belts. In specific use, the tightening belt 32 is used to tighten the patient's chest to protect the wound, and the external fixing belt 31 is used to fix the front shell 1 on the patient's chest. When the rotating shaft 21 in the front shell 1 rotates, the tightening belt 32 will be tightened inward. The tightening force generated when the tightening belt 32 is tightened will promptly remind the patient, and at the same time prevent the patient's chest muscles from abducting with the arm movement, thereby preventing the wound from cracking.

[0034] Since it is inconvenient for patients to make large movements after surgery, the device should be installed as simply as possible. Therefore, in one embodiment, the rear sides of the external fixation belt 31 and the tightening belt 32 are disconnected, and the broken ends of the external fixation belt 31 and the tightening belt 32 are provided with Velcro, which is conducive to quickly installing the device on the patient's body and avoiding large movements of the patient's arms.

[0035] In order to further improve the protection effect, Figure 3 and Figure 4 As shown, in one embodiment, a cam 212 is provided on the rotating shaft 21, and two frame openings 13 are provided on the rear side of the front shell 1. The two frame openings 13 are respectively located on both sides of the middle seam 12, and a contact plate 14 is provided in each frame opening 13. The two contact plates 14 correspond to the two sides of the patient's chest, and each contact plate 14 is respectively rotatably connected to the side of the frame opening 13 away from the rotating shaft 21, and a second elastic member 15 is connected between the plate surface of each contact plate 14 and the inner wall of the front shell 1. The second elastic member 15 can provide an elastic force to contact the contact plate 14 with the cam 212, and the second elastic member 15 can be a spring. It should be noted that in the initial state, the raised portion of the cam 212 does not contact the contact plate 14. When the rotating shaft 21 rotates, the raised portion of the cam 212 will rotate and push the contact plate 14 toward the patient's chest.

[0036] In order to prevent the abutment plate 14 from excessively squeezing the patient's chest, a silicone cushion is further provided on the side of the abutment plate 14 facing the patient's chest to provide soft protection for the patient's chest.

[0037] Preferably, in order to adapt to the patient's chest physiological curve, the rear side of the front shell 1 and the surface of the abutting plate 14 are both curved to improve the comfort of use.

[0038] In one embodiment, a first elastic member 223 is installed between the connecting plate 222 and the inner wall of the front housing 1. The first elastic member 223 can provide elastic force to enable the connecting plate 222 to pull the control wire 23 into the front housing 1. A spring can be used for the first elastic member 223. Under the elastic force of the first elastic member 223, the arm ring 231 can be pulled closer to the front housing 1, counteracting the movement of the patient's arm, which is conducive to reducing the range of movement of the patient's arm.

[0039] Preferably, the external fixing belt 31 is slidably connected to the side plates 33 on both sides of the front shell 1, and the side plates 33 are provided with passage holes 331, one end of the passage hole 331 opens toward one side of the front shell 1 and the other end opens outward, and the control wires 23 passing through the two sides of the front shell 1 pass through the passage holes 331 toward one end of the front shell 1 and pass through the other end. The sliding side plates 33 can adapt to the body shapes of different patients, so that the side plates 33 are always located on both sides of the patient's body, and the passage holes 331 can provide guidance for the pulling of the control wires 23. Under the elastic force of the first elastic member 223, the arm rings 231 are made to lean against the side plates 33, that is, the patient's arms are made to lean against the sides of the body, providing a comfortable body position for the patient.

[0040] The wound fixation device for postoperative rehabilitation of thoracic surgery provided by the present invention is used by tightening the tightening belt 32 and the external fixation belt 31 around the patient's chest, and putting the arm ring 231 on the patient's upper arm to complete the installation of the device; when the patient's upper arm swings, the arm ring 231 will pull the control wire 23, and the transmission structure 22 will move under the pulling of the control wire 23, and then the rotating shaft 21 will be driven to rotate through the rack 221 and the gear 211. When the rotating shaft 21 rotates, it will pull the tightening belt 32 to further tighten the patient, and the tightening pressure will be fed back to the patient in time to serve as a reminder to the patient, while preventing the patient's chest muscles from abducting with the arm movement, thereby preventing the wound from cracking; when the rotating shaft 21 rotates, it will also push the abutment plate 14 through the cam 212 to further fix and protect the patient's chest.

[0041] The present invention utilizes the swinging of the patient's upper arm towards or away from the body when the patient's arm moves, and associates the movement of the patient's upper arm with the tightness of the tightening belt 32 through the tightening mechanism 2. When the patient's upper arm moves, the tightening belt 32 can be tightened in time to protect the patient's wound. At the same time, the tightening pressure is used to remind the patient, which can effectively prevent the wound from cracking due to excessive swing of the patient's arm, and provide timely and effective protection for the patient.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
