Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a compression device for thyroid cancer surgery via the axillary approach. It is suitable for obese patients undergoing thyroid cancer surgery via the axillary approach and is used to compress and stop bleeding in the surgical wound and subcutaneous dissection cavity, while also integrating heat dissipation and dehumidification functions. Background Technology

[0002] Minimally invasive thyroid cancer surgery via the axillary approach is widely used in thyroid surgery because it allows for scarless healing of the neck, resulting in better cosmetic outcomes and meeting the postoperative appearance recovery needs of many patients. Postoperatively, this procedure requires continuous pressure fixation of the axillary surgical incision. This external pressure helps the free skin flap adhere tightly to the deeper tissues, inhibiting subcutaneous hematoma and effusion, reducing swelling in the surgical area, shortening wound healing time, and ensuring optimal postoperative recovery.

[0003] Currently, the mainstream postoperative compression method in clinical practice mostly uses a combination of a saline bag and a diagonal bandage for compression. The weight of the saline bag combined with the tightening force of the bandage applies pressure to fix the axillary wound. However, this traditional compression structure presents many practical problems when applied to obese patients. Obese patients have thick and soft fat layers, requiring a larger axillary surgical incision to maximize the surgical field and ensure clear visualization and smooth operation. Compared to patients of average build, these patients experience greater surgical trauma, more difficult wound healing, and a longer overall recovery period. Furthermore, the thick fat tissue has good elasticity and cushioning properties, significantly reducing the external pressure applied by the saline bag and bandage. This results in a substantial decrease in the effective pressure applied to the surgical incision, making it difficult to maintain a uniform and stable pressure for a long period. Consequently, it is difficult to achieve ideal hemostasis and swelling reduction, and it cannot guarantee proper skin flap adhesion, easily leading to subcutaneous fluid accumulation, misaligned wound healing, and other postoperative complications.

[0004] From the perspectives of postoperative wearing experience and skin care, the armpit area is inherently hidden, small, and enclosed with extremely poor air circulation. Obese patients, with their high metabolism and significant heat loss, experience even higher perceived temperatures. Maintaining a fixed limb posture for extended periods post-surgery easily leads to excessive sweating in the armpit surgical area. Currently used pressure-sealed saline bags are made of sealed plastic, lacking breathability, moisture wicking, and heat dissipation. Sweat generated in the surgical area cannot escape and accumulates between the skin around the incision and the pressure device, creating a hot and humid environment. Under the combined effects of continuous pressure and prolonged sweat immersion, the skin barrier in the armpit is easily damaged, frequently leading to skin conditions such as eczema, itching, redness, and ulceration. This affects postoperative comfort, indirectly increases the risk of wound infection, and delays the normal wound healing process.

[0005] To temporarily alleviate the problem of dampness in the surgical area, clinicians often use a simple method of placing toilet paper on the pressed area to absorb sweat and moisture. This method can only absorb moisture for a short time, and it loses its effectiveness after the tissue becomes saturated. It requires frequent replacement, and patients have limited limb movement after surgery and cannot complete the replacement operation on their own. They rely entirely on medical staff for assistance, which increases the intensity of clinical nursing work, makes the nursing process cumbersome and inefficient, and has limited moisture absorption effect, failing to solve the problem of stuffiness and sweat accumulation at its root. Summary of the Invention

[0006] To address the aforementioned problems in the existing technology, the present invention provides a compression device for thyroid cancer surgery via the axillary approach.

[0007] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: A compression device for thyroid cancer surgery via the axillary approach, comprising: The main compression body has a chamber inside for containing the pressurizing medium. The bottom surface of the main compression body is the contact surface that comes into contact with the patient's skin. The contact surface is provided with an array of breathable protrusions and breathable micropores that penetrate the contact surface.

[0008] The heat dissipation airflow structure includes a breathable channel layer integrated inside the main clamping body, a micro air pump disposed outside the main clamping body, and an air guide pipe for connecting the two. The breathable channel layer is located between the chamber and the contact surface and is in fluid communication with the breathable micropores; the micro air pump delivers airflow into the breathable channel layer through the air guide pipe.

[0009] A fixation device, connected to the main clamping body, is used to continuously fix the main clamping body to the surgical area of ​​the patient's armpit.

[0010] The monitoring and control system includes a temperature and humidity sensor integrated on the contact surface, a blood oxygen saturation sensor attached to the patient's skin, a control unit, and a power module. The control unit is electrically connected to the temperature and humidity sensor, the blood oxygen saturation sensor, and the miniature air pump, respectively.

[0011] Furthermore, the main pressing body has a biomimetic curved surface structure, the curvature of which matches the physiological arc of the area from the front of the armpit to the subclavian region, ensuring uniform pressure distribution.

[0012] Furthermore, the pressurizing medium is a granular or fluid-like constant-temperature material, and the chamber is provided with a sealed opening for replacing or adjusting the pressurizing medium.

[0013] Furthermore, the air-permeable channel layer is a three-dimensional mesh structure made of flexible material or a plate structure with multiple parallel grooves, and a flow equalization plate is provided at the connection between it and the air guide tube.

[0014] Furthermore, the control unit is configured to: The system receives temperature and humidity data collected by the temperature and humidity sensor in real time. When any data exceeds the preset comfort threshold, the system automatically starts the micro air pump and adjusts its speed to change the airflow speed and flow rate.

[0015] The system receives data collected by the blood oxygen saturation sensor in real time. When the local blood oxygen saturation value is detected to be lower than the preset safety threshold, it is determined to be excessive compression and an alarm signal is issued, prompting the user to adjust the tightness of the fixation device or the weight of the pressurizing medium.

[0016] Furthermore, the power module is a rechargeable battery, and the control unit integrates a wireless communication module for transmitting the monitored temperature and humidity, blood oxygen saturation, and air pump operating status data to an external smart terminal.

[0017] The beneficial effects of this invention are: A compression device for thyroid cancer surgery via the axillary approach is designed with targeted structural optimization and functional integration to address the unique body shape characteristics, wound healing difficulties, and skin care pain points of obese patients undergoing thyroid cancer surgery via the axillary approach. It has multiple significant technical advantages and beneficial clinical effects. This invention features a biomimetic curved surface structure for the main compression body, conforming to the physiological curvature of the human armpit. This allows for a comfortable fit within the armpit area. Combined with an internally adjustable granular or fluid-like constant-temperature pressurizing medium, it can flexibly adjust the pressure and fit based on the buffering characteristics of the thick fat layer in obese patients. This overcomes the shortcomings of traditional saline bags where pressure is easily offset by fat elasticity, providing continuous, uniform, and stable pressure to the surgical incision and subcutaneous cavities, effectively preventing pressure attenuation. It efficiently achieves postoperative hemostasis and swelling reduction, promotes close adhesion between the free flap and deep tissues, and avoids postoperative complications such as subcutaneous hematoma, effusion, and flap misalignment. Furthermore, it is suitable for obese patients with larger surgical incisions and longer recovery periods, promoting wound healing and shortening the postoperative recovery cycle. This invention features an array of breathable protrusions and through-hole breathable micropores on the main compression surface, combined with an internally integrated three-dimensional mesh breathable channel layer and a distal micro-pump and air duct forming a heat dissipation airflow structure, creating a complete active ventilation, heat dissipation, and moisture-wicking airflow channel. Unlike traditional plastic sanitary bags that are completely sealed and lack breathability and heat dissipation, this device actively delivers airflow via a micro-pump. After being evenly distributed by a flow equalization plate, the airflow penetrates the breathable channel layer and breathable micropores, continuously removing heat and sweat moisture accumulated in the axillary surgical area, achieving dynamic air circulation. This improves the hot and humid closed environment of the armpit after surgery in obese patients, preventing problems such as eczema, itching, and skin ulceration caused by long-term sweat immersion in the skin, enhancing postoperative comfort, and avoiding the risk of wound infection caused by a damp environment, creating dry and breathable recovery conditions for wound healing.

[0018] The temperature and humidity sensor integrated into the contact surface can monitor the temperature and humidity of the surgical area in real time. When the data exceeds the comfort threshold, the control unit can automatically start and stop and adjust the speed of the micro air pump to dynamically match the heat dissipation and dehumidification needs without frequent manual intervention. At the same time, it is equipped with a blood oxygen saturation sensor to monitor the local skin blood oxygen status in real time and identify excessive pressure. Once the blood oxygen value is lower than the safety threshold, an alarm is triggered immediately to promptly remind medical staff to adjust the tightness of the fixation and the weight of the pressurizing medium. This avoids problems such as poor local blood circulation and skin ischemia damage caused by excessive pressure. It solves the drawbacks of traditional manual pressure application based on experience, inaccurate pressure control, and high nursing risks, and improves the safety and accuracy of postoperative pressure care.

[0019] This device eliminates the cumbersome nursing method of using traditional toilet paper for temporary moisture absorption and frequent replacement. It achieves long-lasting, autonomous dehumidification and heat dissipation through active airflow circulation, eliminating the need for medical staff to repeatedly clean and replace absorbent materials. Simultaneously, it integrates a wireless communication module, which can synchronously upload real-time temperature, humidity, and blood oxygen data, as well as the device's operating status, to an external smart terminal. This allows medical staff to remotely monitor patients' postoperative recovery, simplifying nursing procedures, reducing nursing intensity, and improving clinical nursing efficiency.
