Does ophthalmic surgery need to use 1.4mm OV6946M camera module? The ophthalmic laser 1.4mm OV6946M camera module system consists of two parts: a laser microendoscope lens and a host. The laser microendoscope camera head integrates imaging, illumination and intraocular laser, with a diameter of 0.88mm and a focal length of 1-20mm. . The host includes a high-resolution TV screen, a TV camera, a xenon light source and a semiconductor diode laser with a wavelength of 810 nm.

Using the 1.4mm OV6946M camera module system for surgery is not much different from general vitreous surgery. Because of the function of endoscope, it can perform some operations that are difficult to perform in ordinary vitreoretinal surgery under screen monitoring. Endoscopic guidance when anterior segment conditions (eg, corneal opacity, miosis, posterior capsule opacity, or intraocular gas) prevent it or when conventional methods (eg, under an operating microscope) do not allow proper visualization of certain structures within the eye In this way, the operation can be performed close to the extreme peripheral part of the retina, pars plana, ciliary body and posterior iris area, and the operation of dissection of the anterior segment of PVR and simultaneous intraocular laser photocoagulation can be completed without scleral compression. Medical endoscopes are currently mainly used for glaucoma cyclophotocoagulation and vitreoretinal surgery. Good results have been achieved by using this instrument in the treatment of glaucoma and various types of vitreoretinal diseases.

Challenges and opportunities faced by domestic medical equipment

Clearly aim at the development of medical device science and technology, build an innovation base, and establish an industry-university-research collaboration mechanism for systematic deployment.

According to the chief engineer of Leon Medical, the State Intellectual Property Office issued a document to clarify the top ten industries supported by the state in 2018. Among the medical devices in the branch of the health industry, a total of 6 categories of medical devices will be supported. From this point of view, in the critical period of national economic transformation, the medical device industry, as a field of the real economy, will support. Experts at the meeting also said that the domestic medical device industry has entered a period of rapid development. With policy support and technology, the import substitution of domestic medical devices will press the shortcut key, and cost-effective Chinese manufacturing will launch a stronger challenge for international big brands on a global scale.

Selecting units with advantages in talents, disciplines and resources, focusing on the strategic needs of building a healthy China and reforming the medical system, and building and cultivating a number of innovative medical device innovation platforms are the keys to the development of domestic innovation and technology in the future.

Optimize the layout of scientific and technological innovation, build a high-level scientific and technological innovation base, create an atmosphere of scientific research and innovation, and implement special fund support for innovative medical devices. For example, under the new situation of continuous innovation and development, intelligence and technology promotion of the industry in Nanjing Leon Medical, domestic medical device entrepreneurs can clarify the development context of the industry, focus on innovation capabilities, and produce independent innovations such as medical cold light sources and pneumoperitoneum machines. device of.

For domestic medical device companies to go global and develop, they should not only focus on R&D and technological innovation, but also improve the level of intellectual property declaration and protection, and actively carry out the globalization of intellectual property.

Using cyclophotocoagulation can effectively reduce intraocular pressure, and intraocular pressure can be reduced by 57-65%. In vitreoretinal surgery, vitrectomy, retinal photocoagulation and other operations can be completed under direct vision with the help of a microendoscope, without being affected by the anatomical site or the condition of the anterior segment. Since the endoscope is equipped with a laser, it can reduce the number of instruments entering and exiting the eye during retinal photocoagulation. Postoperatively, an endoscopic camera can be easily used to check for iatrogenic omental tears without indirect ophthalmoscopy.

Some have lower resolutions, especially when working up close. A new slope index endoscopic camera solves this problem. It has a very high resolution and still provides good resolution even at extremely close distances. In the past, the subretinal operation during vitrectomy was viewed through the retina, so the intraoperative operation was "blind". With this endoscope, the omental incision can be avoided, and it can be introduced into the subomentum through the scleral incision and choroid, and other surgical instruments can be introduced through another same incision. Subretinal manipulations can be performed under direct vision from an endoscopic camera. The result is that doctors can operate with considerable accuracy. The subretinal membrane can be carefully stripped between the pigment epithelium and the neuroepithelium without damaging both layers. Choroidal feeding arteries can be identified and photocoagulated, which is difficult during routine subomental procedures. This technique is a major improvement over conventional surgery.
