Description

A protective fixation device after thoracic surgery

Technical Field

The invention belongs to the technical field of medical devices, and in particular relates to a protective fixing device after thoracic surgery.

Background technique

Thoracic surgery mainly includes thoracotomy, thoracoscopic surgery and mediastinoscopic surgery. Thoracotomy: It is mainly a routine surgical method in cardiothoracic surgery. Generally, a wound about 10 cm long is opened in the middle of the sternum. The indications for thoracotomy mainly include active bleeding in the chest cavity, bronchial rupture or damage to the heart and large blood vessels. Thoracoscopic surgery: It is to make a hole in the skin, then put in a camera, and observe the situation in the chest cavity through the screen. Compared with thoracotomy, thoracoscopic surgery has less trauma, faster recovery and better efficacy. The indications for thoracoscopic surgery mainly include chest trauma, esophageal cancer, pulmonary bullae, spontaneous pneumothorax, etc. Mediastinoscopic surgery: It is to perform biopsy on mediastinal lesions, such as mediastinal tumors, mediastinal granulomatous diseases, etc., and it can also achieve a certain therapeutic effect on mediastinal metastatic tumors.

After thoracoscopic surgery, patients need to use a fixation belt to bind and position the wound on their chest according to the healing condition of the incision to prevent the wound from cracking and accelerate wound healing. During postoperative care, patients will inevitably raise their hands and wave their hands, which will pull the chest muscles, causing the surgical wound to be easily pulled, which will cause the wound to crack and is not conducive to wound healing. A device that can protect the wound is needed;

For example, the wound fixation device for postoperative rehabilitation of thoracic surgery with publication number CN116270021A, when used, is tightened around the patient's chest by the tightening belt and the external fixation belt, and the arm ring is placed on the patient's upper arm to complete the installation of the device; when the patient's upper arm swings, the arm ring will pull the control wire, and the transmission structure will move under the pulling of the control wire, and then the rotating shaft will be driven to rotate through the rack and gear, and the tightening belt will be pulled when the rotating shaft rotates, so that it will 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 rotates, the cam will also push the abutment plate at the same time to further fix and protect the patient's chest; although the wound can be fixed, the overall structure of the device is large and complex, and the patient is restrained a lot, and the wearing comfort is greatly reduced, and when caring for the wound, it needs to be opened layer by layer, which is cumbersome and inconvenient.

Specifically, during the assembly stage, the middle part of the medical patch 3 is installed on the lower end of the protective base 1 through the upper end of the protective base 1, and then the extrusion cover 2 is rotated downward along the thread on the upper end of the protective base 1 to be installed, so that the structure of the extrusion cover 2 and the protective base 1 cooperates to fix the medical patch 3 to complete the preliminary work; after the patient undergoes thoracic surgery, the inner side of the lower end of the protective base 1 is installed on the upper part of the wound, and then the medical patch 3 is pasted on the patient's skin. The large-area adhesion of the medical patch 3 can prevent the wound skin from being pulled when the patient moves, causing the wound to tear; then the medicine powder and cotton wool are placed inside the protective base 1 to complete the medicine application; then the middle part of the supporting ridge 5 is installed on the upper end of the extrusion cover 2; then the rotating cover 4 is rotated and installed along the thread on the upper part of the protective base 1 to fix the supporting ridge 5, and the supporting ridge 5 is used to protect a large area around the wound to improve the protection effect; at this point, the protection and fixation of the patient's wound are completed.

Please refer to Figures 4 and 8, the lower end of the protective base 1 is configured to be an inverted funnel shape, which can achieve support away from the wound, reduce the impact of the protective base 1 on the wound, and at the same time allow the lower end of the protective base 1 to have a large enough space to store medicine powder or cotton wool.

Please refer to Figures 4, 7 and 8. The lower end of the protective base 1 and the lower end of the extrusion cover 2 are both provided with a plurality of through holes in a ring shape. The through holes promote air flow inside the protective base 1. The flowing air takes away moisture discharged during wound recovery, thereby accelerating the recovery speed of the wound.

Please refer to Figures 2, 3 and 8. A plurality of limiting ridges 101 are provided on the upper portion of the lower end of the protective base 1. A plurality of integrally formed extrusion ridges 201 are provided on the inner side of the lower end of the extrusion cover 2. The limiting ridges 101 cooperate with the extrusion ridges 201. When the extrusion cover 2 is installed on the upper portion of the protective base 1, the extrusion ridges 201 downwardly squeeze the medical adhesive patch 3 on the upper portion of the limiting ridges 101, thereby achieving multiple extrusion fixations of the medical adhesive patch 3, thereby preventing the protective base 1 and the extrusion cover 2 from being separated from the inside of the medical adhesive patch 3, causing secondary injury to the patient.

Please refer to Figures 1, 2, 4 and 6. The support ridge 5 includes a fixing ring 501, a supporting frame 502 and a contact block 503. The inner side of the fixing ring 501 cooperates with the upper end of the extrusion cover 2 so that the fixing ring 501 is installed into the upper end of the extrusion cover 2. There are multiple supporting frames 502, and one end of the supporting frames 502 is arranged in a ring shape on the outer edge of the fixing ring 501. The deployment of multiple supporting frames 502 can increase the overall protection area of the device. The contact block 503 is fixedly connected to the other end of the supporting frame 502. When the supporting frame 502 is bumped, part of the pressure is shared by the contact block 503, thereby reducing the pressure applied to the protective base 1 and reducing the impact on the wound.

Please refer to Figures 4 and 6. A limiting groove is provided on the inner side of the fixing ring 501, and the limiting groove cooperates with the upper end of the extrusion cover 2. When the fixing ring 501 is installed into the upper part of the extrusion cover 2, the structural limitation of the limiting groove can prevent the fixing ring 501 from rotating, thereby preventing the supporting frame 502 from moving in the protective area of the patient's wound, increasing the patient's discomfort and improving comfort.

Please refer to Figures 1, 2, 4 and 6. The overall configuration of the support skeleton 502 is arc-shaped and made of hard rubber. The rubber's own flexibility and elasticity can better absorb the impact force and reduce the impact on the patient's wound. The contact block 503 is made of plastic material as a whole, and the surface of the contact block 503 is polished. The polishing treatment reduces the friction between the contact block 503 and the medical adhesive patch 3, so that when the support skeleton 502 is impacted, the contact block 503 can slide on the surface of the medical adhesive patch 3, thereby better removing the impact force on the support skeleton 502 and protecting the patient's wound.

Please refer to Figures 1 to 4. The medical patch 3 uses a large area of flexible breathable tape and is provided with multiple ventilation holes, so that the medical patch 3 can be used for a long time without affecting the breathing and normal metabolism of the skin.
