Description

Technical Field

[0001] The utility model belongs to the field of medical instruments, and in particular relates to an arthroscopic lens protective cover. Background Art

[0002] An arthroscope is a rod-shaped optical instrument used to observe the internal structure of joints. It is an endoscope used to diagnose and treat joint diseases. The arthroscope consists of a thin tube with a lens attached to the end. When the tube is inserted into the joint, the internal structure of the joint is displayed on a monitor. This allows direct observation of the internal structure of the joint. Arthroscopy is not only used for diagnosis but has also become widely used in the treatment of joint diseases.

[0003] The lens itself is a valuable and sensitive instrument, requiring frequent daily low-temperature sterilization for specialized surgeries. Existing arthroscopic lens covers often utilize metal boxes, which not only take up a large space but also experience rigid collisions when the boxes collide, easily transmitting the impact force to the lens within, potentially damaging it. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an arthroscopic lens protection cover, which can effectively protect the lens from being bumped.

[0005] The technical solution adopted in this utility model is:

[0006] A protective cover for an arthroscopic lens comprises a box body, a box cover and a limit block made of silicone material. The box cover is arranged on the box body, and the limit block is located in the box body for placing the lens. Through holes are provided on the box body and the box cover. The limit block comprises a first limit block, a second limit block and a third limit block which are arranged in sequence. The second limit block and the third limit block are provided with a card slot for cooperating with the arthroscopic lens. The first limit block is provided with a limit groove for cooperating with the end of the arthroscopic lens. The radial cross-section of the limit groove is trapezoidal and cooperates with the end of the arthroscopic lens.

[0007] Furthermore, the side wall of the second limiting block cooperates with the optical fiber holder of the arthroscope, and the second limiting block is located on a side of the optical fiber holder close to the first limiting block.

[0008] Furthermore, a matching groove for matching with the optical fiber holder is provided on the side wall of the second limiting block.

[0009] Furthermore, clearance holes are provided on the left and right sides of the card slot.

[0010] Furthermore, the box cover is a sliding cover, and a corresponding sliding groove is provided on the box body.

[0011] Furthermore, one end of the box body is opened for the box cover to be inserted into the slide groove, and a locking tooth is provided at the other end of the box body. A locking protrusion for matching with the locking tooth is provided at the end of the box cover, and the locking tooth is located above the slide groove.

[0012] Furthermore, the box body adopts a double-layer structure, including an outer box body and an inner box body, both of which are provided with through holes, and the through holes on the outer box body and the through holes on the inner box body are staggered in the horizontal direction.

[0013] Furthermore, a support column is provided between the outer box body and the inner box body.

[0014] The positive effects of this utility model are:

[0015] This new design is made entirely of soft and elastic silicone, effectively preventing lens damage caused by collisions between protective covers during disinfection.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0021] As attached Figure 1-4As shown, the present invention discloses an arthroscopic lens protective cover, comprising a box body 1, a box cover 2, and a stopper. All three are made of silicone material, which is soft and elastic, effectively preventing rigid impact and protecting the arthroscopic lens placed therein. Specifically, the box cover 2 is mounted on the box body 1, and the stopper is located inside the box body 1 to limit the lens position. Both the box body 1 and the box cover 2 are provided with through holes 3 for low-temperature disinfection.

[0022] In this embodiment, the limit block includes a first limit block 4, a second limit block 5 and a third limit block 6 which are set up at the same time. The first limit block 4 is located on the left side of the box body 1 and is used to cooperate with the handle position of the lens. The third limit block 6 is located on the right side of the box body 1 and is used to cooperate with the head position of the lens. A slot 7 for cooperating with the lens is provided on the second and third limit blocks, and a clearance hole 8 is provided on the left and right sides of the slot 7, so that after the lens is inserted into the slot 7, the position where the slot 7 cooperates with the lens can produce elastic deformation, clamping the lens and preventing it from falling out. A limit groove 9 is provided on the first limit block 4, and the axial cross-section of the limit groove 9 is trapezoidal, which is consistent with the shape of the handle position of the lens, so that it can produce a limiting effect on the lens and prevent it from moving axially to the right. Preferably, the second limit block 5 is located at a position that cooperates with the optical fiber holder 12 of the arthroscopic lens, and the second limit block 5 is located on the side of the optical fiber holder 12 close to the first limit block 4 (that is, Figure 2 The left side as shown in the figure) can also limit the lens to prevent it from moving axially to the left. The first and second limit blocks work together to position the lens to prevent it from moving axially. Combined with the effect of the card slot 7, the lens is completely positioned. After the lens is installed in place, it can effectively prevent the lens from shaking and avoid damage from bumps.

[0023] Preferably, since the optical fiber holder 12 is usually provided with a flange, a matching groove for matching therewith may be provided on the side wall of the second limiting block 5 .

[0024] The box cover 2 can be opened and closed in a manner similar to a hinge, or in the form of a slide cover. In this embodiment, the box cover 2 is a slide cover, and a corresponding slide groove is provided on the box body 1.

[0025] Specifically, one side of the box body 1 is opened for the box cover 2 to be inserted into the slide groove, and a locking tooth 11 is provided at the other end of the box body 1. Figure 2 The right end of the box lid 2 (as shown) is provided with a latching protrusion 10 for engaging with a latching tooth 11. The latching tooth 11 is located above the slide slot. When the latching tooth 11 engages with the latching protrusion 10, the box lid 2 is restrained and closed. To open the box lid 2, simply press the right end of the box lid 2 downward to disengage the latching protrusion 10 from the latching tooth 11, making opening and closing more convenient.

[0026] As a further improvement of the present invention, the box body 1 adopts a double-layer structure, including an outer box body 101 and an inner box body 102, with a support column disposed between the two. The double-layer box body also acts as a buffer, reducing impact force and protecting the lens. In addition, through holes 3 are provided in both the outer box body 101 and the inner box body 102, and the through holes 3 on the two are staggered in the horizontal direction. When performing low-temperature gas or low-temperature steam sterilization, the airflow entering the box body 1 can be slowed down, reducing the impact of the airflow on the lens, thereby protecting the lens.

[0027] The utility model takes into account the material, structure and other aspects, which can effectively reduce the impact and protect the arthroscopic lens placed inside from damage. At the same time, the structure of the limit block can effectively prevent the lens from shaking after it is installed in place, avoiding bumps and damage.
