[0043] Embodiment:

[0044] The embodiment provides a medical camera system, which comprises a medical camera device and an endoscope.

[0045] Referring to Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 10 , the medical camera device comprises an adapter 1, a handle 2, an image processing unit 3, a flexible cable 4 and a button unit 5.

[0046] Specifically referring to Figure 2 , Figure 4 and Figure 10 , the adapter 1 comprises a connecting part 11, a light guide part 12 and a focusing ring 13. The connecting part 11 and the light guide part 12 are generally in the shape of a circular tube, the focusing ring 13 is rotationally arranged at one end of the connecting part 11, and the end of the connecting part 11 at the position of the focusing ring 13 is provided for the endoscope to be inserted, and the other end of the connecting part 11 is fixed to one end of the light guide part 12, so that the connecting part 11 and the light guide part 12 are in communication. The connecting part 11 and the light guide part 12 are generally in a vertical relationship, and an optical element is arranged in the connecting part 11, which is located at the connection between the connecting part 11 and the light guide part 12. Thus, after the endoscope transmits the image to the connecting part 11, the image can enter the light guide part 12 vertically, and then be transmitted to the image processing unit 3. The specific structure of the adapter 1, and the specific way of the endoscope transmitting the image to the image processing unit 3 through the adapter 1 are all prior art, so this embodiment will not be described again.

[0047] Referring toFigure 2 and Figure 4 The outer wall of the focusing ring 13 is provided with an inner notch 131, and the inner notch 131 is provided with anti-skid lines on the side wall. The inner notch 131 can facilitate the medical staff to rotate the focusing 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 in this shape design can be well grasped by the medical staff. In addition, the handle 2 in this shape design can also well match the shape of the image processing unit 3, so as to allow the image processing unit 3 to be accommodated in the handle 2.

[0049] The light guide part 12 is inserted and fitted with the end of the handle 2, so that the handle 2 is installed on the adapter 1, wherein the part of the light guide part 12 away from the connecting part 11 is located in the handle 2 to be connected with the image processing unit 3 in the handle 2. Therefore, the image collected by the endoscope can be transmitted to the image processing unit 3 through the light guide part 12.

[0050] Specifically referring to Figure 6 and Figure 7 One end of the flexible cable 4 is arranged on the handle 2, so as to allow the flexible cable 4 to be electrically connected to the image processing unit 3. The flexible cable 4 can be a power line or a data line, and the flexible cable 4 can power the image processing unit 3 and / or provide data transmission between the image processing unit 3 and the outside world. The flexible cable 4 has good bending deformation ability, so as to allow the handle 2 to obtain a larger activity space.

[0051] The obvious difference 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 with the flexible cable 4. The key unit 5 needs to be electrically connected with the image processing unit 3 through the flexible cable 4, and the key unit 5 is arranged apart from the handle 2 in the extension direction of the flexible cable 4. It is easy to understand that the deformation ability of the part of the flexible cable 4 at the handle 2 is limited by the handle 2, and the deformation ability of the part of the flexible cable 4 at the key unit 5 is limited by the key unit 5. However, 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 bent and deformed, so that the key unit 5 avoids the medical staff, thereby avoiding the misoperation caused by accidental touch.

[0052] It is particularly noted that in the present embodiment, the degree of reduction in the probability of erroneous operation of the key unit 5 is hardly affected by the length of the flexible cable 4 in the portion between the key unit 5 and the handle 2, and the occurrence of erroneous operation of the key unit 5 can be effectively reduced even if the length of the flexible cable 4 in the portion between the key unit 5 and the handle 2 is short, so that in the present embodiment, the key unit 5 can be allowed to maintain a small spacing from the handle 2, for example, the spacing can be not greater than 20 mm (i.e., the length of the flexible cable 4 between the key unit 5 and the handle 2 is not greater than 20 mm), to facilitate normal pressing operation of the key unit 5, and the key unit 5 can maintain good convenience in normal use.

[0053] For the prior art CN117530647A, the utility model concept is as follows: by transferring the key unit 5 to the adapter 1, the spacing between the key unit 5 and the handle 2 is increased, thereby reducing the probability of erroneous touch of the key unit 5, and then reducing the probability of erroneous operation of the key unit 5. Under this utility model concept, there is a strong positive correlation between the probability of erroneous operation of the key unit 5 and the spacing between the key unit 5 and the handle 2. On the other hand, there is a strong negative correlation between the spacing between the key unit 5 and the handle 2 and the operation convenience of the key unit 5. Therefore, there is a strong negative correlation between the probability of erroneous operation of the key unit 5 and the operation convenience of the key unit 5.

[0054] On the contrary, for the medical imaging device of the present embodiment, the utility model concept is as follows: the key unit 5 needs to be further pressed after being erroneously touched by the medical staff to form the erroneous operation of the key unit 5 by the medical staff. Based on this, by transferring the key unit 5 to the flexible cable 4, the flexible cable 4 can be deformed by the characteristic of the flexible cable 4, and when the key unit 5 is erroneously touched, the medical staff can be avoided by the deformation of the flexible cable 4, so as to avoid the further pressing of the key unit 5 as much as possible, reduce the possibility of the erroneous touch action of the medical staff to the erroneous operation action, and then reduce the probability of erroneous operation of the key unit 5. Compared with the prior art, by changing the utility model concept, the correlation between the spacing between the key unit 5 and the handle 2 and the probability of erroneous operation of the key unit 5 is significantly reduced, thereby the negative correlation degree between the probability of erroneous operation of the key unit 5 and the operation convenience of the key unit 5 is effectively limited, and then a theoretical basis is provided for considering the probability of erroneous operation of the key unit 5 and the operation convenience of the key unit 5.

[0055] In other words, by reducing the probability of the key unit 5 being misoperated in the way of inhibiting the conversion from the key unit 5 being mis-touched to the key unit 5 being misoperated, the key unit 5 and the handle 2 can be kept at a smaller interval, so as to maintain better convenience when the key unit 5 is normally operated and controlled, so as to achieve the purpose of simultaneously reducing the probability of the key unit 5 being misoperated and maintaining the convenience of the key unit 5 being normally operated.

[0056] Referring to Figure 1 , Figure 3 , Figure 5 and Figure 12 , the end of the flexible cable 4 away from the handle 2 is provided with an electric coupling joint 41, which can be electrically connected with other electronic devices or power supply. In the extension direction of the flexible cable 4, the key unit 5 and the electric coupling joint 41 are also spaced apart, so the part of the flexible cable 4 between the key unit 5 and the electric coupling joint 41 also has good deformation ability. The part of the flexible cable 4 between the key unit 5 and the electric coupling joint 41 can be deformed, so that the key unit 5 has a larger movable range. Therefore, when the key unit 5 is accidentally touched, the accidental touch behavior can be better avoided, so as to better avoid the accidental touch behavior from being converted into a misoperation behavior, and further reduce the occurrence of the misoperation behavior.

[0057] In order to transfer the key unit 5 from the adapter 1 to the flexible cable 4, the embodiment also provides a specific structure of the key unit 5, which is specifically referred to Figure 6 , Figure 9 and Figure 11 , in the embodiment, the key unit 5 includes a key mounting pipe 51, a key 52 and a first circuit board.

[0058] The key mounting pipe 51 is generally spindle-shaped, and the flexible cable 4 is arranged in the middle of the key mounting pipe 51. The first circuit board is located in the key mounting pipe 51, so that the first circuit board can be electrically connected with the flexible cable 4. The key 52 is mounted on the outer wall of the key mounting pipe 51, so as to allow the first circuit board to be controlled by pressing the key 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 wire core and a flexible cladding layer covering the outside of the conductive wire core. The flexible cladding layer is generally made of insulating and elastic material, such as insulating rubber. The flexible cladding layer is provided with a notch, which is located in the key mounting pipe 51, and the part of the conductive wire core at the notch can reach the outside of the flexible cladding layer through the notch, so as to allow the conductive wire core to be electrically connected with the first circuit board.

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

[0061] Referring to Figure 1 , Figures 3-7 and Figure 12 , the first reinforcing sleeve 42 is sleeved on the flexible cable 4, and is located at the connection between the handle 2 and the flexible cable 4. The first reinforcing sleeve 42 can inhibit the deformation of the end of the flexible cable 4, so that the conductive core can be stably electrically connected with the image processing unit 3. Correspondingly, in order to ensure the realization of the purpose of the utility model in the embodiment, the first reinforcing sleeve 42 and the key unit 5 need to be arranged at intervals in the extension direction of the flexible cable 4.

[0062] Referring to Figure 7 , the first positioning step 21 is arranged on the inner wall of the handle 2, and the part of the light guide part 12 in the handle 2 can press the image processing unit 3 on 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 part 12 to the image processing unit 3, and stabilizing the electrical connection between the image processing unit 3 and the conductive core.

[0063] Further, referring to Figure 8 , the second positioning step 22 is concave in the end face of the handle 2 away from the adapter 1, the outer wall of the image processing unit 3 and the second positioning step 22 form a clamping groove 23, and the end of the first reinforcing sleeve 42 is clamped in the clamping groove 23, so that the first reinforcing 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-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0065] The above-mentioned embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
