Description

Technical Field

[0001] The present invention relates to the technical field of drainage tube fixation, and specifically to a drainage tube fixation device for post-thoracic surgery patients. Background Art

[0002] Thoracic surgery is a medical specialty that specializes in the diagnosis and treatment of organs within the thoracic cavity, mainly referring to the esophagus, lungs, and mediastinal lesions. The field of breast surgery is also classified into this specialty, with pulmonary surgery and esophageal surgery being the main focuses. When there is fluid accumulation in the patient's thoracic cavity, it needs to be treated in a timely manner, and the fluid in the thoracic cavity needs to be drained.

[0003] Traditional drainage methods usually rely on manual adjustment of the patient's position by medical staff. In particular, they have poor adaptability to patients with different body types. The differences in patient body types (such as height and body length) make it necessary to adjust and repeatedly confirm during each fixation process, which increases the operation difficulty and may cause unnecessary delays or misoperations. Although the traditional airbag fixation method can provide a certain degree of stability, in actual use, the fixation is not uniform and may exert a relatively large pressure on the patient, resulting in discomfort for the patient. In traditional drainage tube operations, the position and fixation of the drainage tube often have problems such as inaccurate fixation and easy slippage. Especially when the patient changes body position or during movement, it may cause the displacement of the drainage tube, thereby affecting the drainage effect. The traditional manual operation method relies on the experience and skills of the operator, and is prone to misoperations, resulting in inaccurate fixation or patient discomfort. For post-thoracic surgery patients who require precise positioning, any small error may lead to a decline in the treatment effect. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a drainage tube fixation device for post-thoracic surgery patients, which solves the problems of instability of the traditional fixation method, cumbersome operation during the adjustment process, low comfort level, inaccurate fixation of the traditional drainage tube, and easy detachment.

[0024] The present invention provides a fixing device for a thoracic surgery postoperative drainage tube. It has the following beneficial effects:

[0025] 1. The present invention has the effects of fixing and positioning the drainage tube: The device is specially designed with a fixing and guiding system for the drainage tube. Through the side fixing mechanism, it ensures that the drainage tube can be accurately and stably positioned on the axillary abdominal side of the patient. The design of the static pipeline for the drainage tube avoids the problem of drainage tube displacement caused by movement or improper operation. At the same time, the steering layout design further ensures the accurate guidance of the drainage tube in the working position of the patient, enhances the comfort of the patient and the treatment effect, and can be adjusted individually according to the height and body length of the patient. The hydraulic driving device pushes or pulls the upper limb and lower limb fixing mechanisms in the reverse direction. The activation of the hydraulic driving system ensures that the device can precisely adjust the body position of the patient, so as to meet the needs of patients with different body types. The flexibility of this technology can significantly improve the comfort of treatment and the accuracy of operation.

[0026] 2. The present invention has the efficiency of optimizing the patient's comfort: Through the semi-circular airbag system, the lower limbs (thighs and calves) and upper limbs (upper arms and forearms) of the patient can be stably fixed. This design enables the airbags to evenly distribute the pressure, avoiding the discomfort or compressive injuries that may be caused by traditional fixing devices. After the airbags are inflated, they can provide sufficient fixing force without damaging the skin and soft tissues, and keep the patient stable throughout the treatment process. Through the stable fixation of the airbags at all parts of the body, the patient can maintain a high level of comfort during the treatment process, especially in the initial stage of postoperative rehabilitation. By reducing the movement of the patient, the aggravation of pain or discomfort is avoided, and at the same time, through the stable fixation system, it is ensured that the patient can effectively participate in subsequent treatments and examinations.

[0027] 3. The present invention has an automated displacement and positioning effect: The displacement linkage mechanism combines belt drive and linear conveying force, enabling the patient and the fixing device to move smoothly along the slideway until the precise treatment position is reached. This design not only simplifies manual operation but also reduces the problem of inaccurate positioning caused by human error. Through the linkage motor and gear system, the smoothness and stability of the movement are ensured, thereby enhancing the safety of the patient and the treatment efficiency. During the treatment process, the device can accurately position the patient to the working positions of the scanning gun and the instrument fixing end. By setting precise positioning slideways and positioning rods, the device ensures the synchronization of scanning and treatment operations. The patient can operate devices such as the positioning detector, injection pump, and ventilator in a safe and stable state. This precise coordination not only improves the treatment efficiency but also reduces the risks that may be brought about by improper operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Please refer to the attached Figure 1 - attached Figure 6 , the displacement driving mechanism 3 is located on the base frame 1 and is used for driving the operation of the drainage tube fixing device structure. The displacement driving mechanism 3 includes a fixed frame 31, an external tooth pulley 32, an internal tooth belt 33, a linkage motor 34, an inlay block 35 and a sliding column 36. The fixed frame 31 is fixedly connected to the center of the top of the base frame 1. A group of external tooth pulleys 32 are rotatably connected to both sides inside the fixed frame 31. The two groups of external tooth pulleys 32 are connected by an internal tooth belt 33. The outer side wall of the internal tooth belt 33 is fixedly connected to the inlay block 35. The top of the inlay block 35 is fixedly connected to the sliding column 36. The sliding column 36 is slidably connected inside the driving chute 26. The linkage motor 34 is fixedly connected to the inside of the base frame 1. The top output end of the linkage motor 34 is fixedly connected to the rotating main shaft of a group of external tooth pulleys 32. When the linkage motor 34 is started, the linkage motor 34 drives a group of external tooth pulleys 32 installed on its output shaft to rotate on the fixed frame 31.

The patient first sits on the lower limb fixing pad 81, aligns the thighs with the two groups of mounting rods one 84, and aligns the calves with the two groups of mounting rods two 86. By adjusting the distance between the mounting rod two 86 and the mounting rod one 84, the sliding rod 812 installed on the mounting rod two 86 slides inside the mounting rod one 84, and the mounting rod two 86 also slides on the limit chute block 87 through the sliding frame 85 to adjust the optimal leg length. The two groups of thighs are respectively placed in the semi-circular air bags 89 installed on the two groups of mounting rods one 84, and the two groups of calves are respectively placed on the semi-circular air bags 89 installed on the two groups of mounting rods two 86. Then, the two groups of air pumps two 810 are activated. The air pumps two 810 simultaneously inflate each group of semi-circular air bags 89 through the docking main pipe 811 and the linkage air pipe two 813. The four inflated semi-circular air bags 89 simultaneously fix the two thighs and calves of the patient, fixing the lower body of the patient. The upper body lies on the upper limb fixing pad 71. After adjusting the positions of the four fixing sliders 7824 along the limit slide rail 7721, the four fixing sliders 7824 are adjusted to the most appropriate positions. The two arms of the patient respectively pass through the annular air bags 711 installed inside the two mounting rings 712. There is a group of annular air bags 711 on both the upper arm and the lower arm. By activating the air pump one 79, the air pump one 79 conveys the compressed air into the two groups of linkage air pipes one 710 through a group of air supply main pipes 714 and two groups of air supply sub-pipes 713. The two groups of linkage air pipes one 710 simultaneously supply air to the two groups of annular air bags 711, causing the four annular air bags 711 to expand simultaneously and completely fix the arms of the patient, thus fixing the upper body of the patient. At the same time, the belt transmission member included in the displacement linkage mechanism 4 is activated to generate a linear conveying force, driving the patient lying on the linkage frame 6, the upper limb fixing mechanism 7 and the lower limb fixing mechanism 8 to displace inside the positioning slideway 42, generating a linear conveying force, driving the patient lying on the linkage frame 6, the upper limb fixing mechanism 7 and the lower limb fixing mechanism 8 to displace inside the positioning slideway 42, and gradually displacing to the position of the waiting scanning gun 54. At the same time, the linkage motor 34 is activated. The linkage motor 34 drives a group of external toothed belt wheels 32 installed on its output shaft to rotate on the fixing frame 31. The rotation of this group of external toothed belt wheels 32 drives another group of external toothed belt wheels 32 to rotate through a group of internal toothed belts 33, and makes the internal toothed belt 33 operate. The inlaid block 35 installed on the side wall of the internal toothed belt 33 moves along with the operation of the internal toothed belt 33 and moves along the operation route of the internal toothed belt 33. The sliding column 36 installed on the top of the inlaid block 35 slides on the driving chute 26 installed inside the driving platform 25. The movement of the inlaid block 35 drives the driving platform 25 to move through the sliding column 36,The driving platform 25 is slid laterally on the slide rail 21 along the sliding columns 36 installed at the bottom. When the inlaid block 35 reaches the corner of the operation of the internal gear belt 33, it makes a 270-degree circular displacement. The sliding columns 36 at the top also slide laterally inside the driving chute 26. The inlaid block 35 drives the driving platform 25 to move in the opposite direction, causing the driving platform 25 to perform a reciprocating operation back and forth. The linkage frame 6 fixed through the positioning slideway 42, as well as the upper limb fixing mechanism 7 and the lower limb fixing mechanism 8 on which the lying patient is located, also move linearly with the operation table 41. The gantry 51 included in the detection and positioning mechanism 5 is fixed on the top of the base frame 1, and the cross beam arranged in the middle of the internal gantry 51 that wraps the displacement linkage mechanism 4 is suspended directly below the displacement linkage mechanism 4. Two groups of positioning rods 53 with opposite directions are installed to fix the scanning gun 54 and the instrument fixing end 55 respectively. The instrument fixing end 55 can be used to install devices including a positioning detector, an injection pump, and a ventilator end tube. The linearly reciprocating positioning slideway 42 drives the linkage frame 6, as well as the upper limb fixing mechanism 7 and the lower limb fixing mechanism 8 on which the lying patient is located, to reach the scanning gun 54 and the instrument fixing end 55 located on both sides respectively, so as to perform simultaneous operations on the scanning gun 54 and the instrument fixing ports of the linkage frame 6, the upper limb fixing mechanism 7, and the lower limb fixing mechanism 8 on which the lying patient is located. The drainage tube is guided and used through the side fixing mechanism 9. The side frame 91 included in the side fixing mechanism 9 is placed on one side of the operation table 41. At the same time, a plurality of equally spaced positioning slideways 42 are installed on the operation table 41, forming a static pipeline for the use of the drainage tube. The end of the positioning slideway 42 is installed with a group of 43 arranged in a turning manner through the operation table 41. The 43 is used to guide the drainage tube to one side of the patient's armpit and abdomen, so as to fix the drainage tube and position and guide the drainage tube to the patient's working position.
