Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a microscope objective lens protective cover. Background Art

[0002] Microscopes are commonly used medical instruments in neurosurgery, hand surgery, and other procedures. With the development of microsurgery, surgical microscopes have been widely used. The surgical field of view is small in craniocerebral, ophthalmic, hand surgery, and microsurgery, and the vascular and nerve structures are complex, making the operation more difficult than general surgery. All of these require precise operation under a surgical microscope. In order to meet the hospital infection control requirements for surgical equipment, protective covers need to be used to wrap the microscope head and the end of the surgical microscope arm. A sterile environment must be maintained during the operation.

[0003] An existing Chinese patent (publication number: CN211409377U) discloses a disposable sterile protective cover for a microscope, comprising a protective cover with two strips arranged sequentially on one side, one above the other. One end of each strip is fixedly connected to one side of the protective cover, and the other end is attached to the protective cover with double-sided adhesive. A self-adhesive sticker is also arranged sequentially on the left and right sides of the protective cover, positioned between the two strips. An objective lens cover with release paper is also attached to the protective cover. An eyepiece protective sleeve is also provided at the bottom of the protective cover. In this patent, the sterile cover completely covers the surgical microscope, and then sterile rubber bands and straps are used to fix the objective lens, eyepiece, and other exposed parts. Although this method is relatively simple and easy to operate, there is a risk of the sterile rubber bands loosening during surgery, especially at the objective lens tip, where they are prone to falling off, leading to contamination and poor safety. Utility Model Content

[0004] To address this issue, the present invention provides a microscope objective lens protective cover to solve the problem that the objective lens tip is prone to detachment, leading to contamination and poor safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microscope objective lens protective cover, including an objective lens cover body, a fixing component inside the objective lens cover body, the fixing component including a fixing base, the fixing base being fixedly disposed inside the objective lens cover body, a plurality of connecting shafts being provided on one side of the fixing base, the plurality of connecting shafts passing through the fixing base and being connected to the fixing base via bearings, the plurality of connecting shafts being circumferentially and equidistantly distributed, a blade being fixedly connected to the top end of the connecting shaft, and a gear being fixedly connected to the bottom end of the connecting shaft.

[0006] Preferably, the objective lens cover body has a full-circle limiting groove on its outer side, a rotating cover is fitted over the full-circle limiting groove, multiple sliding grooves are provided on the outer side of the full-circle limiting groove, multiple connecting blocks are fixedly connected inside the rotating cover, and an annular internal gear is fixedly connected to one end of each of the multiple connecting blocks, and the annular internal gear meshes with a gear.

[0007] Preferably, a locking assembly is provided on one side of the objective lens cover body. The locking assembly includes a pressing block, a fixing plate is fixedly connected to one side of the pressing block, an inner groove is opened on one side of the pressing block, the pressing block extends into the inner groove, the fixing plate is disposed inside the inner groove, a spring is fixedly connected to one side of the fixing plate, the other end of the spring is fixedly connected to the side wall of the inner groove, a pawl is fixedly provided on one side of the fixing plate, and an annular inner groove wheel is fixedly provided on the inner wall of the objective lens cover body. The pawl engages with the annular inner groove wheel.

[0008] Preferably, the bottom of the objective lens cover body is adhered with multiple tearable films.

[0009] Preferably, the objective lens cover body has a rubber cover on top, and the rubber cover has a rubber ring on top.

[0010] Preferably, the multiple blades are arranged in an alternating and overlapping manner.

[0011] Preferably, the connecting block extends through the slide groove and is slidably connected to the slide groove.

[0012] Preferably, the rotating cover rotates outside the entire circumferential limiting groove.

[0013] Preferably, the inner edge of the blade is provided with an elastic protective pad.

[0014] The present invention has the following advantages:

[0015] 1. The internal ring gear drives the gear to rotate, which in turn drives the connecting shaft to rotate. The connecting shaft then drives the blades to rotate. The blades rotate clockwise, causing multiple blades to close together and reduce the aperture. This allows multiple blades to contact and lock onto the outer surface of the objective lens, thereby changing the aperture of the objective lens protective cover to accommodate objective lenses of different sizes. At the same time, there is an elastic protective pad at the contact point between the blade and the objective lens, which not only protects the objective lens surface but also serves to fix it in place, preventing loosening and reducing intraoperative contamination.

[0016] 2. The objective lens cover is designed with multiple tearable films, which can be repeatedly removed from the contaminated surface during surgery, improving surgical efficiency. By placing a rubber band on the outer surface of the objective lens, the tight contact between the rubber band and the outer surface of the objective lens increases the sealing of the connection and avoids contamination.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See attached document Figure 1 - Appendix Figure 6 This utility model provides a microscope objective lens protector, including an objective lens cover body 1. A fixing assembly is provided inside the objective lens cover body 1. The fixing assembly includes a fixing base 102, which is fixedly disposed inside the objective lens cover body 1. Multiple connecting shafts 103 are provided on one side of the fixing base 102. The multiple connecting shafts 103 pass through the fixing base 102 and are connected to the fixing base 102 via bearings. The multiple connecting shafts 103 are equidistantly distributed in a circumferential shape. A blade 104 is fixedly connected to the top end of each connecting shaft 103, and a gear 1 is fixedly connected to the bottom end of each connecting shaft 103. 05, the objective lens cover body 1 has a full-circle limiting groove 203 on its outside, a rotating cover 2 is sleeved on the outside of the full-circle limiting groove 203, a plurality of sliding grooves 204 are opened on the outside of the full-circle limiting groove 203, a plurality of connecting blocks 201 are fixedly connected inside the rotating cover 2, a ring internal gear 202 is fixedly connected to one end of the plurality of connecting blocks 201, the ring internal gear 202 meshes with the gear 105, a plurality of blades 104 are staggered and stacked, the connecting blocks 201 pass through the sliding grooves 204 and are slidably connected to the sliding grooves 204, and the rotating cover 2 rotates outside the full-circle limiting groove 203;

[0028] In this embodiment, the rotating cover 2 rotates clockwise, causing the connecting block 201 to rotate. The connecting block 201 drives the annular internal gear 202 to rotate. The annular internal gear 202 drives the gear 105 to rotate. The gear 105 drives the connecting shaft 103 to rotate. The connecting shaft 103 drives the blade 104 to rotate. The blade 104 rotates clockwise, causing multiple blades 104 to close together and reduce the aperture, so that multiple blades 104 contact and lock with the outer surface of the objective lens.

[0029] To achieve the locking purpose, this device employs the following technical solution: A locking assembly is provided on one side of the objective lens cover body 1. The locking assembly includes a pressing block 4, a fixing plate 404 fixedly connected to one side of the pressing block 4, an inner groove 402 formed on one side of the connecting block 201, the pressing block 4 extending into the inner groove 402, the fixing plate 404 disposed within the inner groove 402, a spring 403 fixedly connected to one side of the fixing plate 404, the other end of the spring 403 fixedly connected to the side wall of the inner groove 402, and a claw 405 fixedly provided on one side of the fixing plate 404. The inner wall of the main body 1 of the mirror cover is fixed with an annular inner groove wheel 401. The claw 405 is engaged with the annular inner groove wheel 401. When the pressing block 4 is pressed, the pressing block 4 drives the fixing plate 404 to move. The spring 403 on one side of the fixing plate 404 is compressed. The fixing plate 404 drives the claw 405 to move, so that the claw 405 is no longer engaged with the annular inner groove wheel 401, making it convenient to rotate the rotating cover 2. When the pressing block 4 is released, the spring 403 rebounds and pushes the fixing plate 404 and the claw 405 to move, so that the claw 405 is engaged with the annular inner groove wheel 401, thereby restricting the rotation of the rotating cover 2 and preventing the blade 104 from rotating.

[0030] In order to achieve the purpose of convenient use, the device adopts the following technical solution: multiple tearable films 101 are glued to the bottom of the objective lens cover body 1. During the operation, the tearable films 101 can be removed at any time to improve the efficiency of the operation.

[0031] To achieve the purpose of sealing, the device adopts the following technical solution: the top of the objective lens cover body 1 is provided with a rubber cover 3, the top of the rubber cover 3 is provided with a rubber ring 301, the rubber ring 301 is put on the outer surface of the objective lens, and the rubber ring 301 is in close contact with the outer surface of the objective lens, so as to increase the sealing of the connection and avoid contamination.

[0032] To achieve the purpose of protection, the device adopts the following technical solution: the inner edge of the blade 104 is provided with an elastic protective pad, which can protect the surface of the objective lens and also play a fixing role.

[0033] The usage process of this utility model is as follows: When using this utility model, the rubber ring 301 is placed on the outer surface of the objective lens. The tight contact between the rubber ring 301 and the outer surface of the objective lens increases the sealing at the connection point, preventing contamination. The objective lens cover body 1 is placed on the outer surface of the objective lens. Pressing down the pressing block 4 and rotating the rotating cover 2 causes the pressing block 4 to move the fixing plate 404. The spring 403 on one side of the fixing plate 404 is compressed, causing the fixing plate 404 to move the clasp 405, so that the clasp 405 no longer engages with the annular inner groove wheel 401. Figure 2The rotating cover 2 rotates clockwise, causing the connecting block 201 to rotate. The connecting block 201 drives the annular internal gear 202 to rotate, which in turn drives the gear 105 to rotate. The gear 105 drives the connecting shaft 103 to rotate, which in turn drives the blade 104 to rotate. The blade 104 rotates clockwise, causing multiple blades 104 to close together and reduce the aperture, so that multiple blades 104 contact and lock with the outer surface of the objective lens. When the pressure on the pressing block 4 is released, the spring 403 rebounds and pushes the fixing plate 404 and the pawl 405 to move, so that the pawl 405 locks with the annular inner groove wheel 401, thereby restricting the rotation of the rotating cover 2 and preventing the blade 104 from rotating.

[0034] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
