Detailed implementation manner

[0023] In the context of the rapid development of modern medical technology, minimally invasive surgery has gradually become an important trend in the field of surgical operations. As a representative method of minimally invasive surgery, thoracoscopic surgery occupies an important position in the treatment of chest diseases with its significant advantages such as small trauma, fast recovery, and short hospital stay. The thoracoscopic surgery positioning device, as a key instrument in the surgical process, the development and innovation of its technology are of great significance for improving surgical accuracy and reducing surgical risks.

[0024] The concept of thoracoscopic surgery can be traced back to 1902 and was proposed by the French surgeon Hans Christian Jacobaeus. He first used a thoracoscope for the diagnosis and treatment of pleural effusion. However, in the early stage, due to technical limitations, thoracoscopic surgery was mainly used for simple diagnostic and treatment operations, and the positioning device was relatively simple, mainly relying on the doctor's manual operation and visual judgment.

[0025] With the continuous innovation of optical instruments, television camera technology, microsurgery, and surgical instruments, the technology of thoracoscopic surgery has developed rapidly. In the 1940s, with the progress of optical technology, light sources and microscopes began to be used in thoracoscopes to enhance the observation effect. In the 1960s, the introduction of television camera technology enabled thoracoscopic surgery to observe in real time through a video system, thus improving the accuracy and visualization of the surgery. These technological innovations laid the foundation for the development of the thoracoscopic surgery positioning device.

[0026] Entering the 21st century, with the continuous innovation of surgical instruments, imaging technology, microscopes and fiber optics technology, thoracoscopic surgical positioning devices have also ushered in modern development. Modern thoracoscopic surgical positioning devices not only have high-definition camera and display functions, but can also combine various auxiliary tools and technologies, such as high-definition camera systems, magnifying glasses, microscopes, etc., to improve the accuracy of surgery and the reliability of operation. In addition, with the development of computer and robotics technology, robot-assisted thoracoscopic surgery has also gradually emerged, providing doctors with more precise operations and more flexible instrument control.

[0027] Technical characteristics of positioning device for thoracoscopic surgery

[0028] HD video and display

[0029] Modern thoracoscopic surgical positioning devices usually use high-definition camera systems, which can transmit high-definition images of the surgical area to the display. Doctors can clearly observe the tissue structure, organs and lesions inside the chest cavity through the display, so as to make accurate diagnosis and treatment decisions. The application of high-definition camera and display technology has greatly improved the accuracy and visualization of surgery.

[0030] Assistive tools and technology

[0031] The thoracoscopic surgical positioning device can be combined with a variety of auxiliary tools and technologies to improve the accuracy and safety of the operation. For example, a magnifying glass or microscope can be used to enhance the observation effect; various fine surgical instruments can be used for cutting, suction, suturing and other operations; and a navigation system or 3D printing technology can be combined to assist in surgical positioning and planning.

[0032] Robotic assistance

[0033] Robot-assisted thoracoscopic surgery is a new technology that has been developed in recent years. Through the robot system, doctors can control surgical instruments more accurately and perform more complex and delicate operations. Robot-assisted surgery not only improves the accuracy and safety of surgery, but also reduces the physical burden on doctors and improves surgical efficiency.

[0034] Wireless remote operation

[0035] With the development of wireless technology, wireless remote thoracoscopic surgical positioning devices have gradually become possible. This device has its own light source and wireless image transmission function, which can be placed in the chest cavity and fixed to the chest wall. Doctors can operate surgical instruments and observe the surgical area through remote devices such as remote controllers or smart glasses. The application of wireless remote operation technology provides doctors with a more flexible and convenient surgical method.

[0036] Current application status of positioning devices in thoracoscopic surgery

[0037] Lung surgery

[0038] Thoracoscopic surgical positioning devices are widely used in lung surgeries. For example, in lung cancer resection surgeries, doctors can use the positioning device to accurately determine the location and size of the tumor, thus performing precise resection operations. In addition, the positioning device also plays an important role in surgeries such as the precise positioning and resection of pulmonary nodules and the resection of interlobar septal lesions.

[0039] Mediastinal surgery

[0040] The mediastinum is the area located in the thoracic cavity and contains important structures such as the heart, esophagus, and trachea. Thoracoscopic surgical positioning devices can be used for the examination and treatment of mediastinal diseases, such as the resection of mediastinal tumors and the treatment of mediastinal cysts. Through the positioning device, doctors can clearly observe the organizational structure and pathological conditions of the mediastinal area, thus performing precise operations.

[0041] Pleural surgery

[0042] The pleura is the membrane that covers the lungs and the thoracic cavity wall. Thoracoscopic surgical positioning devices can be used in surgeries such as pleural biopsy, drainage of pleural effusion, and treatment of pleural adhesions. These surgeries usually require precise positioning and operation, and the application of the positioning device greatly improves the precision and safety of the surgery.

[0043] Cardiac surgery

[0044] For some simple heart diseases, such as heart valve diseases and certain congenital heart diseases, thoracoscopic surgery can be used for interventional treatment. In these surgeries, the positioning device can help doctors accurately determine the surgical site and operation range, thus performing precise treatment operations.

[0045] Esophageal and gastric surgeries

[0046] In the treatment of certain gastric and esophageal diseases, thoracoscopic surgical positioning devices also play an important role. For example, in esophageal cancer resection surgeries, doctors can use the positioning device to accurately determine the location and size of the tumor, thus performing precise resection operations. In addition, in surgeries such as esophagogastric anastomosis, the positioning device also provides important assistance.

[0047] Future development directions of thoracoscopic surgical positioning devices

[0048] Intelligence and automation

[0049] With the development of artificial intelligence and automation technologies, thoracoscopic surgical positioning devices will develop towards a more intelligent and automated direction. For example, by integrating advanced image recognition and processing algorithms, the positioning device can automatically identify the pathological site and surgical instruments, thus assisting doctors in performing more precise operations. In addition, by combining robotic technologies, the positioning device can also achieve more flexible and precise operation control.

[0050] Wireless and Remote

[0051] Wireless and remote are important development directions for future thoracoscopic surgery positioning devices. By adopting advanced wireless transmission technology and remote control technology, doctors can perform surgical operations away from the operating table, thereby improving the flexibility and convenience of the surgery. In addition, wireless positioning devices can also reduce components such as cables and connectors during the surgery, reducing surgical risks and infection risks.

[0052] Multi-modal Fusion Imaging

[0053] Multi-modal fusion imaging is one of the important development directions of future medical imaging technology. By fusing multiple imaging technologies (such as CT, MRI, PET, etc.), more comprehensive and accurate medical images can be generated. Applying this technology to thoracoscopic surgery positioning devices can improve the accuracy and visualization of the surgery, providing doctors with richer surgical information and guidance.

[0054] Personalization and Customization

[0055] With the development of 3D printing and personalized medical technology, future thoracoscopic surgery positioning devices will develop towards more personalization and customization. For example, doctors can design and manufacture positioning devices that conform to the individual characteristics of patients according to the specific conditions and surgical needs of patients. Such personalized positioning devices can better adapt to the anatomical structure and surgical needs of patients, improving the accuracy and safety of the surgery.

[0056] Biocompatibility and Safety

[0057] Future thoracoscopic surgery positioning devices will pay more attention to biocompatibility and safety. By adopting advanced biological materials and surface treatment technologies, the stimulation and damage of the positioning device to patient tissues can be reduced, improving the comfort and safety of the surgery. In addition, by strengthening quality control and supervision measures, the quality and safety of the positioning device can be ensured to meet relevant standards and requirements.

At the same time, ways to cooperate with primary medical institutions can be explored to promote the application and popularization of the positioning device at the grass-roots level.

[0071] As an important instrument in the field of minimally invasive surgery, the development and innovation of the thoracoscopic surgery positioning device are of great significance for improving surgical accuracy and reducing surgical risks. Through in-depth analysis and discussion of the existing technologies, we can see that the thoracoscopic surgery positioning device has made remarkable progress, but there are still some limitations. In the future, with the continuous development of technological innovation and medical needs, the thoracoscopic surgery positioning device will develop towards more intelligent, wireless, multi-modal fusion imaging, personalized and customized directions. At the same time, we also need to pay attention to the limitations of the existing technologies and actively explore improvement directions to promote the further development of the thoracoscopic surgery positioning device.

[0072] In the future development, we can expect to see the emergence of more precise, efficient, safe and convenient thoracoscopic surgery positioning devices. These devices will not only improve the accuracy and safety of the surgery, but also reduce surgical risks and costs, bringing better treatment effects and quality of life to patients. At the same time, with the continuous progress and innovation of medical technologies, we also have reasons to believe that the thoracoscopic surgery positioning device will play a more important role in the future medical field.

[0073] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0074] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0075] Referring to Figures 1-4 As shown, this embodiment provides a thoracoscopic surgery positioning device, which includes a base 1. A first connecting rod 2 is fixedly connected to the top surface of the base 1. A first connecting shaft 3 is slidably connected inside the first connecting rod 2. A first connecting seat 4 is slidably connected outside the first connecting rod 2. The first connecting shaft 3 passes through the first connecting seat 4 and is provided with a first limiting mechanism. One end of the first connecting shaft 3 away from the first connecting seat 4 is fixedly connected to a second connecting seat 5. One side of the second connecting seat 5 is rotatably connected to a clamping mechanism. A first driving mechanism is provided between the clamping mechanism and the second connecting seat 5. The first driving mechanism is located inside the second connecting seat 5.

[0076] Before the operation starts, the doctor first adjusts the position of the entire positioning device according to the operation requirements. The base 1 serves as the support of the entire device to ensure the stability of the device. Through the sliding connection between the first connecting rod 2 and the first connecting seat 4, the doctor can adjust the height of the first connecting seat 4 to adapt to the thoracic cavity conditions of different patients. The sliding of the first connecting shaft 3 in the first connecting rod 2 and the limitation of the first limiting mechanism ensure the stability of the first connecting seat 4 after the height is adjusted. The clamping mechanism is used to clamp the thoracoscope or other surgical instruments to ensure their accurate positions.

[0077] Through precise adjustment and fixation mechanisms, the present invention can ensure the accuracy and stability of surgical instruments during the operation, thus greatly improving the precision of the operation. The stable positioning and fine-tuning mechanisms reduce the vibration and deviation during the operation, reduce the operation risk, and enhance the safety of the operation. This device not only improves the efficiency and accuracy of the operation, but also provides a more convenient and safe operation method for doctors, promoting the further development of thoracoscopic surgery technology.

[0078] In a further optimized solution, a first sliding groove 6 is provided in the second connecting seat 5. One end of the first connecting shaft 3 close to the first sliding groove 6 is slidably connected in the first sliding groove 6. A second sliding groove 7 is provided on the top surface of the first sliding groove 6. A limiting strip 8 is provided on the top surface of the first connecting shaft 3 close to the first sliding groove 6. The limiting strip 8 is slidably connected in the second sliding groove 7. A first cavity 9 is provided in the second connecting seat 5. The first cavity 9 communicates with the first sliding groove 6. On one side of the first cavity 9 close to the first sliding groove 6, first baffles 10 are symmetrically fixed. The first baffles 10 are in contact with the first connecting shaft 3. The first driving mechanism is located in the first cavity 9.

[0079] After the first connecting seat 4 slides to a suitable position, the first connecting shaft 3 slides in the first sliding groove 6, and at the same time, the limiting strip 8 slides in the second sliding groove 7 to ensure the stability of the first connecting seat 4 in the horizontal direction. The first baffle 10 is in contact with the first connecting shaft 3 to prevent it from sliding excessively. The first driving mechanism works in the first cavity 9 to drive the clamping mechanism to rotate. Such a setting not only enhances the stability of the positioning device, but also enables the clamping mechanism to rotate flexibly to meet the requirements for different angles during the operation.

[0080] In a further optimized solution, the first driving mechanism includes a first motor 11 fixed to the bottom surface of the first cavity 9. The output shaft of the first motor 11 is fixed with a first bevel gear 12. The first bevel gear 12 is drivingly connected with a second bevel gear 13. The second bevel gear 13 is fixed to the clamping mechanism. Electric control buttons 14 are symmetrically provided on the top surface of the second connecting seat 5. The electric control buttons 14 are electrically connected with a controller 15. The controller 15 is located in the first cavity 9. The controller 15 is electrically connected with the first motor 11.

[0081] The doctor sends an instruction to the controller 15 through the electric control button 14, and the controller 15 controls the first motor 11 to start. The output shaft of the first motor 11 drives the first bevel gear 12 to rotate, and then drives the second bevel gear 13, causing the clamping mechanism to start rotating. The design of the electric control button 14 and the motor enables the doctor to easily control the rotation of the clamping mechanism, improving the efficiency and accuracy of the operation.

[0082] In a further optimized solution, the clamping mechanism includes a second connecting shaft 16 rotatably connected to the second connecting seat 5. One end of the second connecting shaft 16 extends into the first cavity 9 and is fixedly connected with the second bevel gear 13. One end of the second connecting shaft 16 located outside the second connecting seat 5 is fixedly connected with a turntable 18, and one end of the turntable 18 away from the second connecting shaft 16 is fixedly connected with a clamping seat 19.

[0083] The clamping mechanism is rotatably connected to the second connecting seat 5 through the second connecting shaft 16. When the second bevel gear 13 rotates, it drives the second connecting shaft 16 to rotate, and then rotates the turntable 18 and the clamping seat 19 to a suitable angle. The clamping seat 19 is used to clamp the surgical instrument to ensure its accurate position, improving the flexibility and accuracy of the operation.

[0084] In a further optimized solution, a first through hole 20 is provided in the first connecting seat 4. The first through hole 20 is slidably connected to the first connecting rod 2. A third sliding groove 21 is provided in the first connecting rod 2, and the first connecting rod 2 is slidably connected in the third sliding groove 21. A second limiting mechanism is provided between the first connecting seat 4 and the first connecting rod 2.

[0085] The first connecting seat 4 slides on the first connecting rod 2 through the first through hole 20, and at the same time, the third sliding groove 21 provides additional stability for this sliding. The second limiting mechanism is used to fix the position of the first connecting seat 4 on the first connecting rod 2 to prevent it from sliding.

[0086] In a further optimized solution, second cavities 22 are symmetrically provided on one side inside the first connecting seat 4. First limiting mechanisms are symmetrically provided in the second cavities 22. The first limiting mechanism includes fourth sliding grooves 23 symmetrically provided in the second cavities 22. Sliders 24 are slidably connected in the fourth sliding grooves 23. A limiting plate 25 is fixedly connected between the two sliders 24 on the same side of the first connecting shaft 3. The limiting plate 25 is adapted to the first connecting shaft 3 and abuts against the first connecting shaft 3. One end of a spring 26 is fixedly connected to the side of the slider 24 away from the limiting plate 25, and the other end of the spring 26 is fixedly connected in the fourth sliding groove 23.

[0087] In a further optimized solution, a third connecting seat 27 is fixedly connected in the second cavity 22. The top surface of the third connecting seat 27 is fixedly connected with a second motor 28. The output shaft of the second motor 28 is fixedly connected with a connecting roller 29. One end of a connecting rope 30 is wound around the connecting roller 29, and the other end of the connecting rope 30 is fixedly connected to the limiting plate 25.

[0088] When the first connecting shaft 3 slides to a proper position within the first connecting seat 4, the limiting plate 25 abuts against the first connecting shaft 3 under the elastic force of the spring 26 to prevent it from sliding excessively. When it is necessary to adjust the position of the first connecting shaft 3, the limiting plate 25 can be pulled by the second motor 28 and the connecting rope 30 to be temporarily separated from the first connecting shaft 3. After the second motor 28 is started, its output shaft drives the connecting roller 29 to rotate, thereby pulling the connecting rope 30 and separating the limiting plate 25 from the first connecting shaft 3. When it is necessary to fix the position of the first connecting shaft 3, the second motor 28 rotates in reverse, the connecting rope 30 becomes slack, and the limiting plate 25 abuts against the first connecting shaft 3 under the elastic force of the spring 26. The design of the limiting mechanism and the spring 26 provides extra stability for the sliding of the first connecting shaft 3 while not losing flexibility. This design enables the doctor to adjust the position of the first connecting shaft 3 as needed, improving the flexibility and accuracy of the operation.

[0089] In a further optimized solution, the shape of the limiting plate 25 is arc-shaped and fits the first connecting shaft 3.

[0090] In a further optimized solution, on the side of the first connecting seat 4 away from the second cavity 22, a third cavity 31 is provided. A second limiting mechanism is arranged in the third cavity 31. The second limiting mechanism includes first connecting plates 32 symmetrically fixed in the third cavity 31. A contact block 33 is slidably connected between the two first connecting plates 32. The contact block 33 abuts against the side wall of the first connecting rod 2. A lead screw 34 is threadedly connected to the contact block 33. One end of the lead screw 34 away from the contact block 33 is fixedly connected with a third motor 35.

[0091] When it is necessary to fix the position of the first connecting seat 4 on the first connecting rod 2, the third motor 35 is started to drive the lead screw 34 to rotate. The rotation of the lead screw 34 causes the contact block 33 to slide between the first connecting plates 32 until it abuts against the side wall of the first connecting rod 2. This abutting effect fixes the position of the first connecting seat 4.

[0092] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0093] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
