Description

Technical Field

[0001] The present invention relates to the field of medical device technology, and specifically to a new type of portable "fine needle" type, minimally invasive, easy-to-operate arthroendoscopic system, which is particularly suitable for timely and effective diagnosis of joint injuries at any time in daily outpatient clinics due to the needs of the disease, and can perform early and simple treatment. Background Art

[0002] Joint injuries are mainly manifested by varying degrees of pain, snagging, snapping, unsteady walking, and limited mobility, which can seriously affect the patient's quality of daily life. Often due to untimely diagnosis, patients cannot receive effective treatment. Early diagnosis of joint diseases is an important prerequisite for the treatment of joint diseases. After a clear diagnosis, timely and effective treatment can be carried out according to the different disease states of the joints, creating favorable conditions for retaining joint function to the greatest extent, avoiding the further progression of simple lesions to irreversible joint injuries, and providing a practical basis for effective prevention in the future.

[0003] In addition to medical history, symptoms, and signs, the diagnosis of joint injuries is mainly based on medical imaging. At present, the imaging examination methods for joint diseases mainly include traditional X-rays, CT, MRI, etc. However, these imaging devices are heavy and occupy a large space. They cannot be moved after installation, and the appointment time for examination is long, which cannot provide timely and effective diagnosis basis for outpatients.

[0004] Arthroscopy is a minimally invasive examination and treatment device for joint lesions. Its basic structure is an optical system, with a rod mirror system in the center for collecting images, optical fibers for introducing light sources around it, and a metal protective sheath on the outside. Generally, several small incisions of about 0.8-1.0 cm are made in the joint space. Through special light sources, lenses, and display devices, the surgeon completes the examination of each joint chamber under direct vision of the arthroscope. Compared with the indirect display of lesions by X-ray, CT, MRI and other equipment, arthroscopic examination can display lesions more directly and has a higher diagnostic accuracy rate. Once the lesion is found, special minimally invasive instruments can be used for corresponding treatment under the monitoring of the lens. This technology has little interference with the joint, high diagnostic accuracy, and fast postoperative recovery. Compared with traditional open joint surgery, it can not only achieve the same effect, but also has the advantages of obvious less trauma and less pain, and basically does not affect the joint function and the muscle structure around the joint.

[0005] Although arthroscopy has obvious advantages in the diagnosis and treatment of joint diseases, arthroscopic equipment is also large and expensive, requires high repair and maintenance, is not suitable for moving, and requires patients to be hospitalized for a period of time and receive spinal anesthesia or general anesthesia. Therefore, arthroscopy is currently limited to use in hospital operating rooms and has not yet been used in outpatient clinics. The technical advantages have not been fully utilized, which is inconsistent with the urgent need for timely treatment of joint injuries.

[0006] According to the design principle of arthroscopy widely used in hospital operating rooms, a new type of micro-needle arthroendoscopic device is designed, which is miniature, easy to carry, easy to operate, not affected by the environment, and can be used at any time. The device is required to have low trauma during operation, not increase joint damage, and be able to observe lesions in the joints in all directions without leaving blind spots. It can be used to conduct timely examinations and corresponding simple treatments for suspected joint diseases in outpatient clinics or grassroots hospitals and communities, thereby improving the early diagnosis rate of joint diseases, avoiding the cumbersome process of appointment examinations and waiting for hospitalization and surgery, which delays the diagnosis and treatment of diseases, and greatly saving precious medical resources. The goal of "prevention first, early detection, quick treatment, and good rehabilitation" for joint injuries is achieved, and the incidence of joint injuries is reduced to a minimum. Summary of the invention

[0007] The object of the present invention is to provide a miniature, portable, easy-to-operate, and usable miniature needle-type new arthroendoscopic device, which is intended to solve the problems of large size, inconvenient to carry, dependence on external power supply, and need for hospitalization and anesthesia in the prior art. The present invention designs a miniature needle-type new arthroendoscopic device, including a puncture device and a handle, characterized in that: the puncture device is a hollow needle tube, the front end of the needle tube is a bevel, a needle core is arranged in the needle tube, and a connecting bayonet is arranged at the tail end of the needle tube, and the connecting bayonet is connected to a bayonet seat of a puncture device handle, and a soft pipe is arranged at the top of the handle, and an optical fiber is arranged in the soft pipe, and the optical fiber is connected to a miniature camera arranged at the top of the soft pipe, and the rear end of the optical fiber is connected to a light source and a controller arranged in the handle. A fiber lens manipulator is arranged on the handle, and the control end of the fiber lens manipulator is connected to the miniature camera. The controller is composed of a control module, a signal receiving module, and a signal transmission module, the signal receiving module is connected to the optical fiber output end, and the signal transmission module is connected to an external display device. The hollow needle tube is 10-15cm long, with an inner diameter of 1-2mm and an outer diameter of 1.2-2.2mm. The present invention solves the problems of large size, inconvenient to carry, dependence on external power supply, and complex operation of the arthroscopic system in the prior art by optimizing the structural design, integrating an efficient energy system and innovating image transmission technology. The arthroscopy is miniaturized, portable and self-powered, greatly improving its applicability and flexibility in a variety of medical scenarios.

[0011] A new type of micro-needle arthroendoscopic device is shown in the figure, including a puncture device 1 and a handle 2, characterized in that: the puncture device is a hollow needle tube, the front end of the needle tube is a bevel, a needle core 3 is arranged in the needle tube, a connecting bayonet 4 is arranged at the tail end of the needle tube, and the connecting bayonet is connected to a bayonet seat of a puncture device handle 5, a soft pipe 6 is arranged at the top of the handle 2, an optical fiber 7 is arranged in the soft pipe, the optical fiber is connected to a miniature camera 8 arranged at the top of the soft pipe, and the rear end of the optical fiber is connected to a light source 9 and a controller 10 arranged in the handle. A fiber lens manipulator 11 is arranged on the handle, and the control end of the fiber lens manipulator is connected to the miniature camera. The controller is composed of a control module 12, a signal receiving module 13, and a signal transmission module 14. The signal receiving module is connected to the optical fiber output end, and the signal transmission module is connected to an external display device 15. The hollow needle tube is 10-15cm long, with an inner diameter of 1-2mm and an outer diameter of 1.2-2.2mm. 17 is a battery.

[0012] Taking knee arthroscopy as an example, the specific implementation steps are as follows: 1. Routinely disinfect the knee joint and perform local infiltration anesthesia through the anterolateral and anteromedial approaches of the knee joint; 2. Insert the hollow needle tube connected to the handle 5 of the puncture device into the joint cavity, and pull out the needle core 3 after it is inserted into place; take the handle device of the present invention, remove the protective sheath 16 pre-installed on the soft pipe at the factory, and once the protective sheath is pulled out, turn on the light source and the micro camera (there are finished products for sale as medical products), and insert the front slender soft pipe 6 into the hollow needle tube. At this time, the image information captured by the micro camera 8 in the joint cavity is transmitted to the signal receiving module 13 by the optical fiber 7, and is transmitted to the external display device 15 through the signal transmission module 14. The doctor can see the image of the internal structure of the knee joint through the display screen of the external display device, and preliminarily check the various compartments of the knee joint cavity (patellofemoral compartment, medial tibiofemoral compartment, lateral tibiofemoral compartment, medial and lateral groove, intercondylar fossa). If the observation field of view is insufficient, the direction of the micro camera can be controlled by manually adjusting the optical fiber lens manipulator 11 to increase the observation field of view; 3. If the internal structure of the knee joint is blocked by the anterolateral approach, an arthroscopy can be inserted through the anteromedial approach to observe the lesions in the knee joint in all directions without leaving any blind spots; 4. The signal transmission module 14 can also be connected to an external display device through a wireless communication module (Wi-Fi, Bluetooth and other communication protocols) to achieve real-time transmission and storage of image data. By building a cloud platform, these data can be uploaded to the expert database to form a software and hardware intelligent diagnosis and treatment decision-making system integrating "injury collection-diagnosis-evaluation-treatment"; 5. After the operation, remove the arthroscope and cover the puncture needle hole with a Band-Aid. No suturing is required.
