Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, and specifically discloses an electronic arthroscope. BACKGROUND

[0002] An electronic arthroscope is a medical instrument used to observe the internal structure of a joint. It is based on the principle of optical imaging, using a small lens and a light source system to illuminate and observe the inside of the joint. The arthroscope has an internal light source, usually a cold light source. The advantage of a cold light source is that it generates very little heat during illumination, avoiding thermal damage to the joint tissue. The light is transmitted to the front end of the arthroscope through an optical fiber, illuminating the internal structure of the joint. The lens is located at the front end of the arthroscope and is used to collect the light reflected from the inside of the joint. The lens focuses and transmits the light to an imaging sensor. The imaging sensor is usually a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) sensor. These sensors can convert optical signals into electrical signals. The electrical signals generated by the sensor are amplified, filtered, and processed in a series of processes, and then transmitted to an external image display device through a cable.

[0003] Regarding the electronic arthroscope, the patent with the authorization announcement number CN217408790U is an electronic arthroscope. The inner surface of the sleeve block 11 is tightly pressed against the outer surface of the universal ball 7 to fix the arthroscope sheath 10 and the endoscope body 9 on the universal ball 7. This mechanism can adjust the arthroscope sheath 10 and the endoscope body 9 according to the actual situation, improve its adaptability, and facilitate the user's operation.

[0004] Although the above-mentioned device can improve its adaptability and facilitate the user's operation, the lens end of the electronic arthroscope is usually made of medical-grade metal materials. These metal materials have good biocompatibility, which means they usually do not cause serious immune reactions or toxic effects in the human physiological environment. However, the lens end of the arthroscope is hard in texture, and when it is in the body, it may cause collision damage to the internal tissue and mechanical friction damage. UTILITY MODEL CONTENT

[0011] Preferably, the optical socket is fixedly installed with a light source connecting column on the outer wall, and the outer wall of the optical socket is provided with a stress port on both sides.

[0012] Compared with the prior art, the electronic arthroscope has the following beneficial effects:

[0013] 1.

DETAILED DESCRIPTION

[0021] Please refer to Figures 1-5 , the utility model provides a kind of electronic arthroscope, including arthroscope column 5, and one end of arthroscope column 5 is fixedly installed with optical docking seat 2, and the end of arthroscope column 5 away from optical docking seat 2 is fixedly installed with interventional soft seat 56, while the bottom of optical docking seat 2 is fixedly installed with camera docking seat 1, and optical docking seat 2 is docked with camera by camera docking seat 1, and arthroscope column 5 end circumferential outer wall is equipped with through hole 51, and the inside wall of arthroscope column 5 end circumference is equipped with positioning groove 53, while the side of positioning groove 53 is provided with positioning piece 54, and the end of positioning piece 54 is fixedly provided with interventional soft seat 56, and the inside of arthroscope column 5 is fixedly provided with lens 50.

[0022] Working principle: when in use, the arthroscope column 5 is inserted into the patient's body, and the detachable intervention soft seat 56 is provided at the end of the arthroscope column 5. The intervention soft seat 56 is made of soft silicone material and is in the shape of a horseshoe. When the lens end contacts the intra-articular tissues such as cartilage and synovial membrane, it can effectively avoid mechanical damage such as scratching and collision of the metal lens directly on these fragile tissues. Especially during the movement or adjustment of the arthroscope, the intervention soft seat 56 plays a buffering role, reducing the risk of tissue damage. The intervention soft seat 56 can better fit the irregular intra-articular tissue surface. Because silicone has a certain elasticity, it can adapt to different shapes and curvatures of the tissue, making the contact between the lens end and the tissue more stable and stable. This helps to obtain clearer and more stable images, reducing the image shaking or blurring caused by poor contact. For patients, the presence of the intervention soft seat 56 makes the arthroscope feel more gentle in the body. Compared with direct contact with the metal lens, the soft texture of the intervention soft seat 56 can reduce the foreign body sensation and discomfort of the patient to some extent, especially in the case of long operation time, this advantage is more obvious. The horseshoe-shaped intervention soft seat 56 can provide a wider viewing angle for the lens 50. In the joint cavity, this shape can observe more side structures to some extent, unlike the flat end which may have visual dead angles. When the intervention soft seat 56 needs to be disassembled, the sterilized bolt 52 is disassembled, and the five sets of positioning pieces 54 are pulled out from the inside of the five sets of positioning grooves 53, completing the replacement or cleaning and disinfection of the intervention soft seat 56.

[0023] As a preferred embodiment, the intervention soft seat 56 is made of soft silicone material and is in the shape of a horseshoe, and the surface of the intervention soft seat 56 is provided with an inclined surface 57, and the inclination angle of the inclined surface 57 is 60 degrees.

[0024] The arthroscope column 5 and the intervention soft seat 56 are positioned and installed through the positioning groove 53 and the positioning piece 54, and the cross section of the positioning groove 53 and the positioning piece 54 is in the shape of a dovetail; the diameter of the arthroscope column 5 and the intervention soft seat 56 is consistent.
