[0002] The medical camera device is a device that cooperates with an endoscope to examine tissue lesions. It mainly includes an optical mount, a handle, an image processing unit and a button unit. The optical mount is used to connect the endoscope. The optical mount is fixed to the handle. The image processing unit is installed in the handle to allow the endoscope to transmit the optical image to the image processing unit. The button unit is electrically connected to the image processing unit, and the image processing unit can be controlled by the button unit.

[0003] In general, the industry usually sets the key unit on the handle to facilitate the operation of the key. However, this also makes the key unit easy to be touched by mistake, which in turn causes the key unit to be misoperated. In order to improve this situation, taking the prior art CN117530647A as an example, the key unit will be transferred to the optical bayonet. The larger the distance between the key unit and the handle, the smaller the risk of the key unit being accidentally touched and misoperated. However, on the other hand, the convenience of operation of the key unit will also deteriorate synchronously. Summary of the invention

[0004] Based on this, it is necessary to provide a medical imaging device and a medical imaging system to address the problem that the key unit in the medical imaging device cannot take into account both the risk of misoperation and the convenience of operation.

[0013] The key unit of the present invention includes a key mounting tube, a key and a first circuit board. The flexible cable is passed through the middle of the key mounting tube. The first circuit board is located in the key mounting tube and is electrically connected to the flexible cable. The key is mounted on the outer wall of the key mounting tube. The key is used to control the first circuit board.

[0014] The flexible cable of the present invention comprises a conductive core and a flexible sheath wrapped around the outside of the conductive core, the flexible sheath is provided with a notch, the notch is located in the button mounting tube, the portion of the conductive core at the notch is located outside the flexible sheath and is electrically connected to the first circuit board.

[0016] The flexible cable of the present invention is provided with a first reinforcement sleeve, the first reinforcement sleeve is located at the connection between the handle and the flexible cable, and the first reinforcement sleeve and the button unit are arranged at intervals.

[0017] The inner wall of the handle of the present invention is provided with a first positioning step, one end of the adapter is inserted into the handle and presses the image processing unit onto the first positioning step, so that the image processing unit is positioned in the axial direction of the handle.

[0020] The beneficial effects of the present invention are:

[0021] When the key unit is accidentally touched, the portion of the flexible cable between the handle and the key unit can be bent and deformed, so that the key unit avoids the accidental touch, thereby suppressing the transformation of the key unit being accidentally touched into the key unit being misoperated, thereby reducing the probability of the key unit being misoperated. This method of reducing the probability of the key unit being misoperated effectively reduces the correlation between the probability of the key unit being misoperated and the distance between the key unit and the handle, thereby effectively reducing the correlation between the probability of the key unit being misoperated and the convenience of operating the key unit.

[0022] On this basis, the key unit is allowed to maintain a smaller distance from the handle, thereby maintaining the convenience of the key unit during normal operation while effectively reducing the probability of the key unit being misoperated, thereby achieving the purpose of simultaneously reducing the probability of the key unit being misoperated and maintaining the convenience of normal operation of the key unit.

[0043] Example:

[0044] This embodiment provides a medical imaging system, including a medical imaging device and an endoscope.

[0045] See also Figure 1 , Figure 3 , Figure 5 , Figure 6 and Fig.10 The medical imaging device includes an adapter 1, a handle 2, an image processing unit 3, a flexible cable 4 and a button unit 5.

[0046] See Figure 2 , Figure 4 and Fig.10 , the adapter 1 includes a connecting portion 11, a light guide portion 12 and a focus ring 13. The connecting portion 11 and the light guide portion 12 are both generally in the shape of a circular tube, and the focus ring 13 is rotatably arranged at one end of the connecting portion 11. The end of the connecting portion 11 where the focus ring 13 is located can be plugged in with the endoscope, and the other end of the connecting portion 11 is fixed to one end of the light guide portion 12 so that the connecting portion 11 and the light guide portion 12 are connected. The connecting portion 11 and the light guide portion 12 are generally in a vertical relationship, and an optical element is arranged in the connecting portion 11, and the optical element is located at the connection between the connecting portion 11 and the light guide portion 12, so that after the endoscope transmits the image to the connecting portion 11, the image can vertically enter the light guide portion 12 and then be transmitted to the image processing unit 3. The specific structure of the adapter 1 and the specific method in which the endoscope transmits the image to the image processing unit 3 through the adapter 1 are both prior arts, so they are not described in detail in this embodiment.

[0047] See also Figure 2 and Figure 4 The outer wall of the focus ring 13 is provided with an inner notch 131 , and the side wall of the inner notch 131 is provided with anti-slip grooves. The inner notch 131 can facilitate medical staff to rotate the focus ring 13 with one hand.

[0048] In this embodiment, the handle 2 is generally in the shape of a circular tube, and the cross-sectional area of ​​the handle 2 gradually decreases in the axial direction of the handle 2. The handle 2 can be easily grasped by medical personnel under this shape design. In addition, the handle 2 can also well match the shape of the image processing unit 3 under this shape design, so that the image processing unit 3 can be accommodated in the handle 2.

[0049] The light guide portion 12 is plugged into the end of the handle 2 so that the handle 2 can be installed on the adapter 1, wherein the portion of the light guide portion 12 away from the connecting portion 11 is located inside the handle 2 to be connected to the image processing unit 3 inside the handle 2, so that the image collected by the endoscope can be transmitted to the image processing unit 3 via the light guide portion 12.

[0050] See Figure 6 and Figure 7 One end of the flexible cable 4 is disposed on the handle 2 to allow the flexible cable 4 to be electrically connected to the image processing unit 3. The flexible cable 4 may be a power cable or a data cable, and the flexible cable 4 may supply power to the image processing unit 3 and / or transmit data between the image processing unit 3 and the outside world. The flexible cable 4 has good bending deformation capability to allow the handle 2 to obtain a larger activity space.

[0051] What is obviously different from the prior art is that the key unit 5 is installed on the flexible cable 4, and the key unit 5 is electrically connected to the flexible cable 4. The key unit 5 can only be electrically connected to the image processing unit 3 through the flexible cable 4, and at the same time, in the extension direction of the flexible cable 4, the key unit 5 and the handle 2 are arranged at intervals. It is easy to understand that the deformation ability of the part of the flexible cable 4 at the handle 2 will be limited by the handle 2, and the deformation ability of the part of the flexible cable 4 at the key unit 5 will be limited by the key unit 5, but the deformation ability of the part of the flexible cable 4 between the handle 2 and the key unit 5 is not obviously limited. Therefore, when the medical staff accidentally touches the key unit 5, the part of the flexible cable 4 between the handle 2 and the key unit 5 can be deformed by bending, so that the key unit 5 avoids the medical staff, thereby avoiding the erroneous operation caused by the accidental touch.

[0052] It is particularly important to note that, in the present embodiment, the degree to which the probability of misoperation of the button unit 5 is reduced is almost unaffected by the length of the flexible cable 4 between the button unit 5 and the handle 2. Even if the length of the flexible cable 4 between the button unit 5 and the handle 2 is very short, the occurrence of misoperation of the button unit 5 can be effectively reduced. Therefore, in the present embodiment, the button unit 5 can be allowed to maintain a smaller spacing from the handle 2, for example, the spacing may be no greater than 20 mm (that is, the length of the flexible cable 4 between the button unit 5 and the handle 2 is no greater than 20 mm), so as to facilitate normal pressing operations on the button unit 5, and the button unit 5 can maintain good convenience during normal use.

[0053] For the prior art CN117530647A, the inventive concept is as follows: by transferring the key unit 5 to the adapter 1, the distance between the key unit 5 and the handle 2 is increased, thereby reducing the probability of the key unit 5 being touched by mistake, and then reducing the probability of the key unit 5 being misoperated. Under this inventive concept, there is a strong positive correlation between the probability of the key unit 5 being misoperated and the distance between the key unit 5 and the handle 2. On the other hand, there is a strong negative correlation between the distance between the key unit 5 and the handle 2 and the ease of operation of the key unit 5. As a result, there is a strong negative correlation between the probability of the key unit 5 being misoperated and the ease of operation of the key unit 5.

[0054] In contrast, for the medical imaging device of this embodiment, the inventive concept is as follows: the key unit 5 needs to be further pressed after being accidentally touched by the medical staff, which will cause the medical staff to misoperate the key unit 5. Based on this, by transferring the key unit 5 to the flexible cable 4, the flexible cable 4 can be deformed to avoid the medical staff when the key unit 5 is accidentally touched, thereby avoiding the key unit 5 from being further pressed as much as possible, reducing the possibility of the medical staff's accidental touch action being transformed into an erroneous operation action, and then reducing the probability of the key unit 5 being misoperated. Compared with the prior art, this embodiment changes the inventive concept so that the correlation between the distance between the key unit 5 and the handle 2 and the probability of the key unit 5 being misoperated is significantly reduced. Therefore, the negative correlation between the probability of the key unit 5 being misoperated and the convenience of operating the key unit 5 is effectively limited, thereby providing a theoretical basis for taking into account both the probability of the key unit 5 being misoperated and the convenience of operating the key unit 5.

[0055] In other words, by suppressing the conversion of the button unit 5 being accidentally touched to the button unit 5 being accidentally operated, the probability of the button unit 5 being accidentally operated is reduced. This method allows the button unit 5 and the handle 2 to maintain a smaller distance, thereby maintaining better convenience when the button unit 5 is normally operated and controlled, so as to achieve the purpose of simultaneously reducing the probability of the button unit 5 being accidentally operated and maintaining the convenience of normal operation of the button unit 5.

[0056] See also Figure 1 , Figure 3 , Figure 5 and Fig.12 , an electric coupling connector 41 is provided at the end of the flexible cable 4 away from the handle 2, and the electric coupling connector 41 can be electrically connected to other electronic devices or power supplies. Among them, in the extension direction of the flexible cable 4, the button unit 5 and the electric coupling connector 41 are also arranged at intervals, so the part of the flexible cable 4 between the button unit 5 and the electric coupling connector 41 also retains good deformation ability. The part of the flexible cable 4 between the button unit 5 and the electric coupling connector 41 can be deformed so that the button unit 5 obtains a larger movable range. Therefore, when the button unit 5 is accidentally touched, the accidental touch behavior can be better avoided, thereby better preventing the accidental touch behavior from being converted into an erroneous operation behavior, and then further reducing the occurrence of erroneous operation behavior.

[0057] In order to transfer the key unit 5 from the adapter 1 to the flexible cable 4, this embodiment also provides a specific structure of the key unit 5, see Figure 6 , Fig. 9 and Fig.11 In this embodiment, the key unit 5 includes a key mounting tube 51, a key 52 and a first circuit board.

[0058] The button mounting tube 51 is generally spindle-shaped, and the flexible cable 4 is passed through the middle of the button mounting tube 51. The first circuit board is located in the button mounting tube 51 so that the first circuit board can be electrically connected to the flexible cable 4. The button 52 is mounted on the outer wall of the button mounting tube 51 so that the first circuit board can be controlled by pressing the button 52, and the first circuit board can transmit signals to the image processing unit 3 through the flexible cable 4.

[0059] The flexible cable 4 includes a conductive core and a flexible sheath covering the outside of the conductive core. The flexible sheath is generally made of an insulating and elastic material, such as insulating rubber. A notch is provided on the flexible sheath, and the notch is located in the key mounting tube 51. The portion of the conductive core at the notch can reach the outside of the flexible sheath through the notch, so as to allow the conductive core to be electrically connected to the first circuit board.

[0060] Preferably, the inner wall of the end of the button mounting tube 51 extrude the flexible cladding, so that the button mounting tube 51 can be positioned on the flexible cable 4, ensuring that the electrical connection between the conductive core and the first circuit board is stable.

[0061] See also Figure 1 , Figure 3-Figure 7 and Fig.12 , a first reinforcement sleeve 42 is sleeved on the flexible cable 4, and the first reinforcement sleeve 42 is located at the connection between the handle 2 and the flexible cable 4. The first reinforcement sleeve 42 can suppress the deformation of the end of the flexible cable 4, so that the conductive core can be stably electrically connected to the image processing unit 3. Accordingly, in order to ensure the realization of the purpose of the invention in this embodiment, in the extension direction of the flexible cable 4, the first reinforcement sleeve 42 and the button unit 5 need to be arranged at a distance.

[0062] See Figure 7 A first positioning step 21 is provided on the inner wall of the handle 2. The portion of the light guide 12 inside the handle 2 can press the image processing unit 3 onto the first positioning step 21 so that the image processing unit 3 is positioned in the axial direction of the handle 2, thereby stabilizing the image transmission of the light guide 12 to the image processing unit 3 and stabilizing the electrical connection between the image processing unit 3 and the conductive core.

[0063] For further information, see Figure 8 The end surface of the handle 2 away from the adapter 1 is concave to form a second positioning step 22, and the outer wall of the image processing unit 3 and the second positioning step 22 are surrounded to form a slot 23. The end of the first reinforcement sleeve 42 is snapped into the slot 23, so that the first reinforcement sleeve 42 can be assembled on the handle 2 through the cooperation of the image processing unit 3.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
