Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

[0049] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0050] Auditory bulla windowing in rats is a biomedical research that focuses on observing and studying the structure and function of the inner ear, as well as the effects of drugs on the inner ear. The purpose of this surgery is to expose the internal structure of the auditory bulla so that researchers can observe and record the activities of the auditory system, such as: nerve conduction studies, drug and therapy testing, research on the mechanism of hearing loss, regeneration research, model construction, etc. Currently, in most studies where auditory bulla windowing is required in rats, forceps, scissors, etc. are used to perform the windowing operation on the rat auditory bulla. However, conventional tweezers, scissors, etc. are non-specialized instruments and require separate disinfection pretreatment. Not only are they inconvenient to operate, they can also easily cause postoperative bleeding or even infection in experimental subjects.

[0051] The window opening device provided in this solution is a special window opening device. It can quickly eject a professional window opener for auditory bulla window opening through the cooperation of the first drive component and the second drive component. It is convenient, fast, targeted and special, which improves the operational efficiency of the auditory bulla window opening experiment and effectively avoids the problem of poor recovery of experimental subjects caused by non-specialized instruments.

[0052] Example 1

[0053] Reference Attachment Figure 1 and attached Figure 2 The window opening device provided in this embodiment includes a mounting tube 1, a first drive assembly 2, a second drive assembly 3 and a window opener 4. An outlet 11 is provided at one end of the mounting tube 1. The first drive assembly 2 and the second drive assembly 3 are sequentially provided on the mounting tube 1 along its axial direction. The second drive assembly 3 is closer to the outlet 11 relative to the first drive assembly 2. The first drive assembly 2 has a first state and a second state relative to the mounting tube 1 along the axial direction of the mounting tube 1. When the first drive assembly 2 changes from the first state to the second state, a force toward the outlet 11 is generated. Ejection force, the second drive component 3 has a third state and a fourth state relative to the mounting tube 1 along the radial direction of the mounting tube 1. When the second drive component 3 changes from the third state to the fourth state, the restriction on the ejection force is removed so that the ejection force acts toward the ejection port 11; the window opener 4 is arranged along the axial direction of the mounting tube 1 on the side of the second drive component 3 away from the first drive component 2 in the mounting tube 1, and the window opener 4 is movably connected to the first drive component 2 so as to be able to be ejected from the ejection port 11 under the action of the ejection force.

[0054] It can be understood that in order to solve the problem of inconvenience in operation caused by the lack of special instruments when performing window opening on the auditory bulla of rats, and even cause postoperative bleeding and infection in experimental subjects; the window opening device provided in this embodiment uses the mounting tube 1 as a accommodating structure for the window opener 4, and provides a force carrier for the operator to hold or take it, and is equipped with a first drive component 2 and a second drive component 3. The two cooperate to complete the power storage process of the ejection force and the rapid ejection process of the window opener 4, thereby realizing the discontinuity of the window opening process and ensuring the operability, accuracy and controllability of the window opening device as a special instrument during the window opening process.

[0055] The window opening device provided in this embodiment can be used, but is not limited to, in the research operation of opening the auditory bulla of rats. As long as a fast and precise ejection-type opening operation is required, the window opening device provided in this embodiment can be used to complete it.

[0056] Reference Attachment Figure 1 and attached Figure 2 The mounting tube 1 is a rigid cylindrical structure with a hollow interior. Its cross-sectional shape can be circular, rectangular, triangular, etc., as long as the internal space is sufficient to arrange the various drive components and the window opener 4. Its radial and axial dimensions can be designed and adjusted according to actual needs and are not limited here. In this embodiment, one end of the mounting tube 1 is provided with an outlet 11, and the other end can be open or closed. The shape of the outlet 11 is not limited here, and it can be adapted to the window opener 4.

[0057] Reference Attachment Figure 2 The window opener 4 is a rigid structure and can be, but is not limited to, a rod, a needle, a hollow cylinder, etc. In this embodiment, the window opener 4 can be a hollow structure. A pointed opening can be provided at the enabling end of the window opener 4, i.e., the end facing away from the first drive assembly 2, to improve the ability of the window opener 4 to penetrate the auditory bulla and also to remove the auditory bulla tissue at the windowed position. The pointed opening here can be a needle-shaped design, which is easily understood by those skilled in the art and will not be described in detail here. In this embodiment, the size and shape of the window opener 4 are not limited and can be designed and adjusted according to actual needs. For example, for rat auditory bulla windowing, the window opener 4 can be set as a cylindrical structure with an axial dimension of 30 mm, a diameter of 2 mm, and an enabling end length of 2 mm based on the experience of windowing experiments and the specifications of rats. In this embodiment, the window opener 4 is a disposable device, and thus the window opening device can also be a disposable device. Alternatively, the window opener 4 in this embodiment is replaceable, and thus the window opening device can be a reusable device.

[0058] The first drive assembly 2 can change state in the axial direction of the mounting tube 1, for example, sliding toward or away from the ejection port 11. The first drive assembly 2 may include an elastic member, which may be, but is not limited to, a spring. Furthermore, the ejection force can be generated by compressing the elastic member as the first drive assembly 2 approaches the ejection port 2. Accordingly, when the elastic member is in a free state, the first drive assembly 2 is in a first state, and when the elastic member is compressed to its shortest state, the first drive assembly 2 is in a second state. It is also understood that the first drive assembly 2 may have a reserved drive end 23 outside the mounting tube 1 to provide a force application position for the operator.

[0059] The second drive assembly 3 can change state in the radial direction of the mounting tube 1, for example, by expanding and contracting radially inward and outward along the mounting tube 1. The second drive assembly 3 can support the generation of the ejection force. When the first drive assembly 1 approaches the ejection port 11, the second drive assembly 3 can maintain an axially obstructive effect on the mounting tube 1, separating the elastic member and the window opener 4. For example, it can interfere with the elastic member to cause it to be continuously compressed, thereby generating the ejection force. The second drive assembly 3 then changes state to release the interference with the elastic member, either by disengaging from the elastic member or by allowing the elastic member to pass through the second drive assembly 3, thereby releasing the ejection force and causing it to act on the window opener 4. Accordingly, when the second drive assembly 3 is not within the mounting tube 1, it can be in the third state, and when the second drive assembly 3 is within the mounting tube 1, it can be in the fourth state. It can be understood that in this embodiment, the state changes of the first drive assembly 2 and the second drive assembly 3 are independent and do not interfere with each other. Therefore, when performing the window opening operation, the operator can freely separate the accumulation of force and the opening of the window, thereby improving the convenience and controllability of the operation.

[0060] According to the above, the window opening device provided by the present application can generate an ejection force through the state change of the first drive component 2, and then cooperate with the state change of the second drive component 3 to eject the window opener 4 for rapid window opening. It not only provides a professional window opening instrument, but also can realize intermittent or continuous window opening operation through the cooperation of the first drive component 2 and the second drive component 3, providing a convenient and safe window opening instrument for opening the auditory bulla of rats; it can effectively solve the problem of operational inconvenience caused by the lack of special instruments when opening the auditory bulla of rats, and even cause postoperative bleeding and infection in experimental subjects.

[0061] Further, refer to the attached Figure 2In the window opening device provided in this embodiment, in a specific implementation, the first driving assembly 2 includes a first driving portion 21 and a first elastic portion 22; the first elastic portion 22 is coaxially arranged with the mounting tube 1, one end of the first elastic portion 22 movably contacts the second driving assembly 3, and the other end is connected to the first driving portion 21; the first driving portion 21 is slidably connected to the mounting tube 1 along the axial direction of the mounting tube 1, so as to be able to compress the first elastic portion 22 along the axial direction of the mounting tube 1 to generate the ejection force, and the first driving portion 21 passes through the mounting tube 1 to form a driving end 23;

[0062] The first driving portion 21 slides toward the emission port 11 along the axial direction of the mounting tube 1 , which is the process in which the first driving component 2 changes from the first state to the second state.

[0063] It is understandable that in order to enable the first drive assembly 1 to generate an ejection force, the present embodiment sets the first drive assembly 2 to include a first drive portion 21 and a first elastic member 22; the first drive portion 21 is a rigid structure and can be in the form of a block, rod, plate, etc., as long as it can provide a drive end 23 and provide a resistance drive for the first elastic member 22. In the present embodiment, a guide hole 12 extending along the axial direction of the mounting tube 1 can be provided on the wall of the mounting tube 1, so that the first drive portion 21 passes through the guide hole 12 to form the drive end 23, and the guide hole 12 can also provide a guide for the first drive portion 21 to slide along the axial direction of the mounting tube 1. The end of the first drive portion 21 located inside the mounting tube 1 is connected to the first elastic portion 22, and when an external force is applied to the drive end 23, the first elastic portion 22 can be compressed toward the outlet 11 to generate an ejection force. The first elastic part 22 can be, but is not limited to, a spring, a rubber tube or other structures. The connection between the first elastic part 22 and the first driving part 21 can be adhesive or embedded. In this embodiment, the first driving part 21 can be set to a straight line shape, so that it can pass through the guide hole 12 vertically; the first driving part 21 can also be set to an L-shape, with one end passing through the guide hole 21 and the other end passing through the first elastic part 22 to guide the deformation of the first elastic part 22.

[0064] Further, refer to the attached Figure 1 In the window opening device provided in this embodiment, in a specific implementation, the first driving assembly 2 further includes a limiting portion 24; the limiting portion 24 is movably provided on the outer wall of the mounting tube 1, and the limiting portion 24 has a first relative position and a second relative position relative to the mounting tube 1. When the limiting portion 24 is in the first relative position, the first driving portion 21 can slide back and forth along the axial direction of the mounting tube 1. When the limiting portion 24 is in the second relative position, the limiting portion 24 is placed on the side of the first driving portion 21 away from the outlet 11.

[0065] It is understood that in order to maintain the first elastic member 22 in a compressed state and thus maintain the ejection force at a maximum state, thereby providing stable support for the ejection of the window opener 4, a limiting portion 24 is provided in this embodiment. The limiting portion 24 is a rigid structure and can be in the form of a block, a strip, a sphere, etc., as long as it can contact the first driving member 21 to provide a limit. In this embodiment, the limiting portion 24 can be configured to be rotatable on the outer wall of the mounting tube 1 about a direction parallel to the axial direction of the first driving member 21. When the first driving member 21 needs to slide toward the ejection port 11, the limiting portion 24 is located outside the range of the guide hole 12, that is, it has a first relative position with the mounting tube 1. After the first driving member 21 completes its sliding toward the ejection port 11 and compresses the first elastic member 22, the limiting portion 24 rotates to at least partially locate in the guide hole 12 on the side of the first driving member 21 facing away from the ejection port 11, that is, it has a second relative position with the mounting tube 1, thereby limiting the first driving member 24 and preventing it from moving away from the ejection port 11. It can be understood that the specific position of the limiting portion 24 relative to the guide hole 12 can be designed and adjusted according to actual needs. The limiting portion 24 may directly contact the first driving portion 21 after rotation, or there may be a slight gap between the limiting portion 24 and the first driving portion 21 after rotation. As long as the ejection force generated by the first elastic member 22 when the limiting portion 24 contacts the first driving portion 21 is sufficient to eject the window opener 4, it can be sufficient.

[0066] Further, refer to the attached Figure 7 and attached Figure 8 , the window opening device provided in this embodiment, in a specific implementation, a limiting hole 13 and a turning groove 14 are sequentially provided on the mounting tube 1 along the first direction a, the first direction a being perpendicular to the axial direction of the mounting tube 1; the limiting hole 13 includes a first limiting hole 131 and a second limiting hole 132 which are interconnected, the first limiting hole 131 being arranged along the axial direction of the mounting tube 1, the second limiting hole 132 being located in the same plane as the first limiting hole 131, and the second limiting hole 132 being perpendicular to the first direction a and the axial direction of the mounting tube 1, the second limiting hole 132 extending to the sliding track of the first driving part 21; a second elastic part 15 is provided in the turning groove 14, the second elastic part 15 being arranged along the first direction a, and one end of the second elastic part 15 facing the limiting hole 13 abuts against the limiting part 24.

[0067] It will be appreciated that, to achieve variable positioning of the limiting portion 24 relative to the mounting tube 1, in this embodiment, a limiting hole 13 and a limiting slot 14 are provided on the mounting tube 1. The limiting hole 13 can be a cross-shaped opening formed by a first limiting hole 131 and a second limiting hole 132, and can be provided on the outer wall of the mounting tube 1. Furthermore, to limit the position of the first driving portion 21, in this embodiment, the second limiting hole 132 is extended to the guide hole 12, so that when the limiting portion 24 is within the second limiting hole 132, it can block the first driving portion 21 in the direction of the guide hole 12. Accordingly, the limiting portion 24 can be an elongated structure to fit between the first limiting hole 131 and the second limiting hole 132. Furthermore, when the limiting portion 24 is located in the first limiting hole 131, the first driving portion 24 can reciprocate within the guide hole 12. When the limiting portion 24 rotates and is located in the second limiting hole 132, the first driving portion 21 cannot reciprocate within the guide hole 12. The setting of the limiting part 24 in this embodiment can also limit the first driving part 21 before opening the window, avoiding the first driving part 21 from sliding in the direction of the outlet 11 by mistake, thereby preventing the first driving part 21 from sliding in the direction of the outlet 11. In this embodiment, the vertical condition can be mutually perpendicular or approximately perpendicular. Correspondingly, in order to realize the rotation of the limiting part 24, a turning groove 14 is provided in this embodiment. The turning groove 14 can be formed by the concave inner wall of the mounting tube 1, or it can be additionally provided in the mounting tube 1, as long as it does not restrict the movement of the first elastic part 22, so as to provide space for the rotation of the limiting part 24; the turning groove 24 provides space for the rotation of the limiting part 24 and provides a resistance end for the second elastic part 22. When the limiting part 24 needs to be rotated from the first limiting hole 131 to the limiting hole 132, the limiting part 24 is pressed along the first direction a to disengage from the limiting hole 13 and sink into the turning groove 14. At this time, the second elastic part 15 is compressed to generate an ejection force in the opposite direction of the first direction a. After the limiting part 24 is rotated, the external force is removed so that it pops out of the second limiting hole 132 under the action of the ejection force in the opposite direction of the first direction a. It is understood that a rotating end 241 can be provided on the limiting portion 24, and the rotating end 241 corresponds to the intersection of the first limiting hole 131 and the second limiting hole 132, so that the rotating end 241 will not be interfered with by the two holes when the limiting portion 24 is rotated. It is understood that in this embodiment, only the plate body that fits the second elastic portion 15 can extend from the interior of the installation tube 1. In this case, the rotating space of the limiting portion 24 is the internal space of the installation tube 1.

[0068] Further, refer to the attached Figure 5 and attached Figure 6In the window opening device provided in this embodiment, in a specific implementation, the second drive assembly 3 includes a third drive part 31 and a fourth drive part 32, and the third drive part 31 and the fourth drive part 32 are movably arranged relative to each other along any radial direction of the mounting tube 1, and the third drive part 31 and the fourth drive part 32 can approach or move away from each other; the third drive part 31 is provided with a first opening 33 on one end facing the fourth drive part 32, and the axial direction of the first opening 33 is parallel to the axial direction of the mounting tube 1; the fourth drive part 32 is provided with a second opening 34 on one end facing the third drive part 31, and the axial direction of the second opening 34 is parallel to the axial direction of the mounting tube 1; wherein, when the third drive part 31 and the fourth drive part 32 approach each other until the first opening 33 and the second opening 34 are coaxial, the process of the second drive assembly 3 changing from the third state to the fourth state is reached. When the second drive assembly 3 changes from the third state to the fourth state, the ejection force acts on the window opener 4 through the first opening 33 and the second opening 34.

[0069] It can be understood that in order to realize the state change of the second drive component 3 so as to realize whether the window opener 4 is ejected or not, the second drive component 3 in this embodiment is configured to include a third drive part 31 and a fourth drive part 32, both of which are rigid structures. The two are arranged opposite to each other along the radial direction of the mounting tube 1, and a pressing end 35 can be reserved outside the mounting tube 1 to achieve the two approaching each other along the radial direction of the mounting tube 1 when an external force presses the pressing end 35. Then, the third drive part 31 and the fourth drive part 32 are in the third state when they are not pressed, and are in the fourth state when they are pressed close to the first opening 33 and the second opening 34 are coaxial. In this embodiment, the shapes and sizes of the first opening 33 and the second opening 34 are not restricted, as long as they are compatible with the first elastic member 22 to ensure that the first elastic member 22 can pass through smoothly; in this embodiment, when the second drive assembly 3 is in the fourth state, the third drive part 31 and the fourth drive part 32 can be stacked or partially stacked in the axial direction of the mounting tube 1, and thus the first opening 33 and the second opening 34 can be coaxial; when the third drive part 31 and the fourth drive part 32 are not pressed, the end of the first elastic member 22 away from the first drive part 21 can abut against part of the third drive part 31, or part of the fourth drive part 32, or simultaneously abut against part of the third drive part 31 or part of the fourth drive part 32, and when the two openings overlap, the first elastic part 22 can release the ejection force on the window opener 4.

[0070] Further, refer to the attached Figure 5 and attached Figure 6In the window opening device provided in this embodiment, in a specific implementation, the second drive assembly 3 further includes a third elastic member 36 and a fourth elastic member 37; the third elastic member 36 is arranged in parallel with the third drive portion 31 in the mounting tube 1, and the two ends of the third elastic member 36 respectively abut against the inner wall of the mounting tube 1 and the end of the third drive portion 31 facing the fourth drive portion 32; the fourth elastic member 37 is arranged in parallel with the fourth drive portion 32 in the mounting tube 1, and the two ends of the fourth elastic member 37 respectively abut against the inner wall of the mounting tube 1 and the end of the fourth drive portion 32 facing the third drive portion 31.

[0072] Further, refer to the attached Figure 5 and attached Figure 6 In the specific implementation of the window opening device provided in this embodiment, a first thinning area 311 is provided on the side of the third driving part 31 facing the exit 11, so as to form a first step 312 on the side of the first thinning area 311 away from the fourth driving part 32, and the first opening 33 is provided in the first thinning area 311; a second thinning area 321 is provided on the side of the fourth driving part 32 away from the exit 11, so as to form a second step 322 on the side of the second thinning area 321 away from the third driving part 31, and the second opening 34 is provided in the second thinning area 321; when the third driving part 31 and the fourth driving part 32 approach each other until the first step 312 and the second step 322 conflict with each other, the first opening 33 and the second opening 34 are coaxial.

[0073] It can be understood that in order to ensure the precise coaxial position of the first opening 33 and the second opening 34 and improve the operational convenience of the window opening device, in this embodiment, the first thinning area 311 and the second thinning area 321 are respectively provided on the third driving part 31 and the fourth driving part 32 to form the first step 312 and the second step 322 respectively. Then, when the third driving part 31 and the fourth driving part 32 are pressed, the overlapping parts of the first thinning area 311 and the second thinning area 321 in the axial direction of the mounting tube 1 gradually increase until the first step 312 and the second step 322 conflict with each other. At this time, the first opening 33 and the second opening 34 are coaxial. The structural limit allows the operator to directly judge the injection timing of the window opener 4 without manual adjustment or searching for the injection timing of the window opener 4, thereby greatly improving the efficiency and accuracy of the injection. It can be understood that when the third driving part 31 and the fourth driving part 32 are not pressed, the first thinning area 311 and the second thinning area 321 can be separated from each other in the radial direction of the mounting tube 1, can be connected to each other, or can be partially overlapped.

[0076] It is understood that, to provide flexibility and adaptability for the windowing device, this embodiment includes a detachable illumination tube 5, which can be, but is not limited to, threaded. When conducting experiments on photochemically induced cochlear microcirculatory disturbances in rats, the illumination tube 5 can be attached to the mounting tube 1. After the window is opened, green light illumination can be directly applied, thus avoiding the need for cumbersome experimental equipment, tedious initial preparation, and time-consuming and inconvenient access. Furthermore, the illumination tube 5 in this embodiment can be designed and adjusted to its luminous parameters based on experimental or research needs. For example, when conducting experiments on photochemically induced cochlear microcirculatory disturbances in rats, the illumination tube 5 can emit green light with a wavelength of 540±40 mm and an intensity of 500-600 mW / cm, thereby cooperating with a photosensitizer to induce ischemic damage to the inner ear for subsequent experimental observation and research. In this embodiment, the light tube 5 can be sequentially provided with a filter 52, a lens 53, a lamp bead 54, a lamp holder 55, a battery 56, and a compression spring 57 within the barrel 51. A switch 58 is provided on the barrel wall of the barrel 51 in conjunction with the battery 56. The switch 58 can be a sliding switch or a push-type switch. The operation of the switch 58 in conjunction with the internal lamp bead 54, lamp holder 55, battery 56, and compression spring 57 is readily understood by those skilled in the art and will not be described in detail here. It should be noted that the color of the filter 52 can be changed according to actual needs. This can be achieved by forming a modular structure that forms a filter cover and is detachably connected to the barrel 51 in a threaded manner, thereby achieving replaceability.

[0079] It can be understood that in order to achieve the replaceability of the window opener 4 and improve the recycling rate of the window opening device, in this embodiment, the installation cylinder 1 is configured to include a first cylinder 16 and a second cylinder 17 that can be connected by threads, and the first drive component 2 and the second drive component 3 are both arranged in the first cylinder 16 to ensure its stability. When the window opener 4 is replaced, it is only necessary to disassemble the second cylinder 17 for replacement, which will not interfere with the first drive component 2 and the second drive component 3 and will not affect the status of the first drive component 2 and the second drive component 3. When there is no need to perform a window opening operation, the window opener 4 can be installed without avoiding misoperation. In order to ensure that the window opener 4 is stable in the second cylinder 17 and can be accurately pushed out by the first elastic part 22, a limiting cylinder 6 is provided in this embodiment. The limiting cylinder 6 can cooperate with the outlet 11 to support the two ends of the window opener 4, and then the window opener 4 can be manually inserted. The installation is convenient and quick. The axial size of the limiting cylinder 6 can be designed and adjusted according to actual needs. It can not only play a supporting role but also play a guiding role when the window opener 4 is pushed out, thereby ensuring the accuracy of the ejection direction and orientation of the window opener 4.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this embodiment should be included within the scope of protection of this embodiment.
