Technical Field
[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to a disassembly and assembly structure of a sterile handle of a surgical shadowless lamp. Background Art
[0002] The surgical shadowless lamp is used to illuminate the surgical site to best observe small, low-contrast objects at different depths in the incision and body cavity. Since the surgeon's head, hands and instruments may cause interfering shadows on the surgical site, the surgical shadowless lamp should be designed to eliminate shadows as much as possible and minimize color distortion. When performing surgery, the surgeon will use his hands to adjust the handle of the shadowless lamp. The handle is used for focusing. The spot diameter can be adjusted by rotating the handle, so the handle of the shadowless lamp must be sterile. Usually, before the operation, the nurse will remove the handle of the shadowless lamp and send it to the high-temperature disinfection room for sterilization, then take it back to the operating room and install it on the handle of the shadowless lamp.
[0003] However, most shadowless lamp handles are not convenient to disassemble, which makes it difficult to disinfect some hidden parts inside the handle, resulting in insufficient disinfection of the handle and affecting the surgical effect. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1-7 The utility model provides a technical solution: a disassembly and assembly structure of a sterile handle of a surgical shadowless lamp, comprising: a fixing seat 1 connected to the shadowless lamp, the outside of the fixing seat 1 being slidably inserted into the inside of a detachable sterile handle 2.
[0027] A slider 13 is provided inside the fixing seat 1 , and a side of the slider 13 is fixedly connected to one side of the clamping block 11 . A return spring 16 is provided inside the slider 13 , and an inner ring of one end of the return spring 16 is sleeved on the outside of one side of the reaction base 15 .
[0028] A circular through hole 12 is provided on the side of the fixing seat 1, and the hole wall of the circular through hole 12 is slidably sleeved on the outside of one side of the slider 13. A circular cavity 14 is provided inside the slider 13, and the cavity wall of the circular cavity 14 is slidably sleeved on the outside of the reset spring 16. Both ends of the reset spring 16 are supported between the cavity wall of the circular cavity 14 and the side wall of the reaction base 15.
[0029] Furthermore, when it is necessary to install the fixing seat 1 and the detachable sterile handle 2 together, it is only necessary to insert the outer part of the fixing seat 1 into the detachable sterile handle 2. After insertion, the card block 11 is inserted into the card slot 23, so that the fixing seat 1 cannot be pulled out from the detachable sterile handle 2. Under the elastic force of the reset spring 16, the slider 13 maintains the tendency to move in the direction of the circular through hole 12, thereby ensuring that the card block 11 is inserted into the card slot 23, preventing the card block 11 from being separated from the card slot 23 and causing the connection between the fixing seat 1 and the detachable sterile handle 2 to be unstable. The above-mentioned installation method makes the fixing seat 1 and the detachable sterile handle 2 more convenient and quick to install.
[0030] A second circular through hole 21 is formed on the side of the detachable sterile handle 2 . The hole wall of the second circular through hole 21 is slidably sleeved on the outside of the button 22 . One side of the button 22 is aligned with one side of the slider 13 .
[0031] The inner wall of the detachable sterile handle 2 is provided with a clamping groove 23, and the clamping groove 23 is located on both sides of the second circular through hole 21. The groove wall of the clamping groove 23 is movably sleeved on the outside of the clamping block 11.
[0032] Furthermore, when it is necessary to separate the fixed seat 1 from the detachable sterile handle 2, it is only necessary to press the button 22 toward the slider 13, so that the button 22 moves in the direction of the slider 13, and then the button 22 pushes the slider 13 to move in the direction of the reaction base 15. During this process, the slider 13 compresses the reset spring 16. At the same time, the slider 13 also drives the card block 11 to move in the direction of the reaction base 15, so that the card block 11 is moved out of the card slot 23. At the same time, the fixed seat 1 is pulled out from the detachable sterile handle 2, so that the fixed seat 1 can be separated from the detachable sterile handle 2. The whole separation process is simpler and faster. After the fixed seat 1 is separated from the detachable sterile handle 2, the inside and outside of the detachable sterile handle 2 can be disinfected, making the disinfection more thorough.
[0033] A notch 17 for the button 22 to pass through is provided on the side of the fixing seat 1 at the position of the circular through hole 12 , and the notch 17 is located below the circular through hole 12 .
[0034] Furthermore, when the outer part of the fixing seat 1 is inserted into the detachable sterile handle 2, in order to prevent the button 22 from obstructing the fixing seat 1, a notch 17 is provided below the circular through hole 12 for the button 22 to pass through.
[0035] Working principle: when it is necessary to install the fixing seat 1 and the detachable sterile handle 2 together, it is only necessary to insert the outside of the fixing seat 1 into the detachable sterile handle 2. After insertion, the card block 11 is inserted into the card slot 23, so that the fixing seat 1 cannot be pulled out from the detachable sterile handle 2. Under the elastic force of the reset spring 16, the slider 13 maintains the tendency to move in the direction of the circular through hole 12, thereby ensuring that the card block 11 is inserted into the card slot 23, preventing the card block 11 from being separated from the card slot 23 and causing the connection between the fixing seat 1 and the detachable sterile handle 2 to be unstable. The above installation method makes the fixing seat 1 and the detachable sterile handle 2 more convenient and quick to install. When it is necessary to separate the fixing seat 1 from the detachable sterile handle 2, it is only necessary to press the button 22 toward the slider 13, so that the button 22 moves in the direction of the slider 13, and then the button 22 pushes the slider 13 to move in the direction of the reaction base 15. During this process, the slider 13 compresses the reset spring 16. At the same time, the slider 13 also drives the card block 11 to move in the direction of the reaction base 15, so that the card block 11 is moved out of the card slot 23. At the same time, the fixing seat 1 is pulled out of the detachable sterile handle 2, so that the fixing seat 1 can be separated from the detachable sterile handle 2, and the whole separation process is simpler and faster.
