[0047] An embodiment of the first aspect of the present application provides a medical handheld camera. As Figures 1 to 4 shown, the medical handheld camera includes a housing 10, an adapter ring 3, an imaging assembly 4, and a heat conducting member. Among them, the housing 10 includes a main body portion 11 and a lens barrel portion 12 fixedly connected to the main body portion 11. One side of the adapter ring 3 is fixedly connected to the side of the lens barrel portion 12 away from the main body portion 11, and the other side of the adapter ring 3 is used to connect to an optical component. The imaging assembly 4 is disposed inside the housing 10, and the imaging assembly 4 includes a circuit board 41.

[0048] In an embodiment of the present application, as Figure 1 and Figure 2 shown, the lens barrel portion 12 can be generally in the shape of a hollow cylinder, and the main body portion 11 and the lens barrel portion 12 can be connected as an integral structure. Further, as Figure 1 shown, the medical handheld camera may further include a lens 5 whose shape and size match the hollow structure inside the lens barrel portion 12. The lens 5 is disposed inside the lens barrel portion 12, and the lens barrel portion 12 can be used to carry and fix the lens 5. Among them, the material of the housing 10 includes, but is not limited to, aluminum, aluminum alloy, copper, copper alloy, stainless steel, etc.
[0049] The adapter ring 3 is used to connect the optical component and the side of the lens barrel portion 12 away from the main body portion 11, and the hollow part of the adapter ring 3 corresponds to the position of the lens 5. In addition, the imaging assembly 4 is used to collect image information, and the imaging assembly 4 is electrically connected to a controller outside the medical handheld camera. The imaging assembly 4 is also used to transmit the collected image information to the external controller. Among them, the imaging assembly 4 and the external controller can be connected by a cable in a wired manner. Specifically, one end of the cable can be electrically connected to the imaging assembly 4, and the other end extends out of the housing 10 and the wire harness sleeve 8 and is electrically connected to the external controller. The wire harness sleeve 8 is also used to wrap and fix the cable. The imaging assembly 4 and the external controller can also be connected by a wireless signal. The present application does not limit this. Among them, the external controller can be a computer, etc. The controller can include a display screen to display the image information transmitted by the imaging assembly 4.
[0050] Among them, the optical component can be a light-transmitting and lighting structure. The imaging component 4 can collect clearer pictures through the optical component and the lens 5. Taking a medical handheld camera as an example of a medical endoscope camera, the optical component can include a hollow tube. One end of the hollow tube is connected to the adapter ring 3, and the other end of the hollow tube is connected to the optical rigid endoscope and the lighting component. Among them, the hollow tube can be a flexible tube or a rigid tube. The end of the hollow tube connected to the optical rigid endoscope and the lighting component can extend into the human body, so that the imaging component 4 can collect the image information inside the human body through the optical rigid endoscope and the lighting component, etc.
[0051] In the embodiment of the present application, a processing chip, a sensor, etc. are integrated on the circuit board 41. Therefore, during the operation of the medical handheld camera, the circuit board 41 generates a lot of heat. The first heat-conducting member and the second heat-conducting member can conduct the heat generated by the circuit board 41 to the adapter ring 3 and the wire harness sleeve 8 respectively, realizing the heat dissipation of the medical handheld camera.
[0052] Optionally, the material of the wire harness sleeve 8 includes silicone or rubber. Silicone and rubber have good heat conductivity, which can make the heat of the circuit board 41 better transfer to the outside of the medical handheld camera through the wire harness sleeve 8.
[0053] Optionally, the material of the adapter ring 3 includes at least one of copper, aluminum, copper alloy, and aluminum alloy to have good heat conductivity. The material of the adapter ring 3 can also be other materials with good heat-conducting performance, and the present application does not limit this.
[0054] During the operation of the medical handheld camera provided in the embodiment of the present application, the first heat-conducting member can conduct and transfer the heat generated by the circuit board 41 to the lens barrel part 12, and finally transfer it from the lens barrel part 12 to the adapter ring 3 fixedly connected thereto and export it from the medical handheld camera. The second heat-conducting member can conduct and transfer the heat generated by the circuit board 41 to the wire harness sleeve 8 outside the housing 10. Among them, the heat generated by the circuit board 41 in the imaging component 4 is exported by the adapter ring 3 located at the end of the medical handheld camera and / or by the wire harness sleeve 8 located at the tail of the medical handheld camera, which can quickly export the heat in the medical handheld camera, has good heat dissipation performance, and improves the product performance of the medical handheld camera. In addition, during the use of the medical handheld camera, medical staff can hold the medical handheld camera through the main body part 11 of the housing 10. Therefore, the heat is exported by the adapter ring 3 located at the end or the wire harness sleeve 8 located at the tail, which can reduce the probability of heat conduction to the main body part 11 and reduce the probability of phenomena such as high temperature rise in the main body part 11, improve the use experience of medical staff, and further improve the product performance of the medical handheld camera.
[0055] In some embodiments, the second heat conducting member includes an inner shell 211. The inner shell 211 and the front shell portion 101 of the shell 10 enclose a receiving space, and the imaging assembly 4 is disposed in the receiving space. There is a gap 20 between the inner shell 211 and the rear shell portion 102 of the shell 10. The inner shell 211 is provided with a cable port for connecting a cable outside the shell 10 to the imaging assembly 4 through the cable port. The second heat conducting member further includes a heat conducting member 221. The heat conducting member 221 is placed between the circuit board 41 and the inner shell 211 to conduct the heat of the circuit board 41 to the inner shell 211 and conduct it to the wire harness sleeve 8 wrapping the cable through the inner shell 211.
[0056] In the embodiments of the present application, as Figure 10 shown, the volume of the rear shell portion 102 is larger than the volume of the inner shell 211, and the opening directions of the rear shell portion 102 and the inner shell 211 are opposite to the opening direction of the front shell portion 101. The opening side of the inner shell 211 is fixedly connected to the opening side of the front shell portion 101 to form a receiving space for accommodating structures such as the imaging assembly 4 between the inner shell 211 and the front shell portion 101. The rear shell portion 102 is sleeved outside the inner shell 211, and the opening side of the rear shell portion 102 abuts against the opening side of the front shell portion 101.
[0057] In the embodiments of the present application, the shell 10 includes a front shell portion 101 and a rear shell portion 102. The front shell portion 101 includes a main body portion 11 and a lens barrel portion 12. The inner shell 211 can be locked and connected to the front shell portion 101 of the shell 10 through fasteners or the like. There is a gap 20 between the inner shell 211 and the rear shell portion 102, which can greatly reduce the probability of the heat generated by the inner shell 211 being transferred to the rear shell portion 102, so that the heat can be better conducted to the wire harness sleeve 8 through the inner shell 211 and then conducted outside the medical handheld camera, further improving the heat conduction performance of the medical handheld camera. The heat conducting member 221 is used to enable the heat generated by the circuit board 41 to be introduced into the inner shell 221 faster, so that the circuit board 41 can be quickly cooled.
[0058] Optionally, as Figure 3 shown, the heat conducting member 221 may include a heat conducting plate 2211 located between the circuit board 41 and the inner shell 211. The heat conducting plate 2211 is used to conduct the heat of the circuit board 41 to the inner shell 211. The heat conducting member 221 may further include a heat conducting pad 2212. The two sides of the heat conducting pad 2212 are respectively in contact connection with the heat conducting plate 2211 and the inner shell 211. The heat conducting pad 2212 is used to conduct the heat conducted from the circuit board 41 to the heat conducting member 221 to the inner shell 211 more quickly, so that the circuit board 41 can be quickly cooled.
[0059] Optionally, the heat conducting pad 2212 includes at least one of heat conducting foam, heat conducting silica gel and heat conducting gel.
[0060] Optionally, the front housing part 101 and the inner housing 211 can be directly connected by means such as bonding or magnetic attraction connection, or the front housing part 101 and the inner housing 211 can also be connected by fastening with fasteners such as bolts and screws. This application does not limit this. Specifically, as Figure 8 and Figure 9 shown, a plurality of third through holes 13 can be provided on the side of the front housing part 101 close to the inner housing 211. Correspondingly, a plurality of fourth through holes 2111 matching the third through holes 13 are provided on the side of the inner housing 211 close to the front housing part 101. Screws are passed through the third through holes 13 and the fourth through holes 2111 to fixedly connect the front housing part 101 and the inner housing 211. In the embodiment of this application, since the inner housing 211 is located inside the rear housing part 102, the fasteners for connecting the inner housing 211 and the front housing part 101 are also arranged inside the rear housing part 102, reducing the influence of the external environment on the fasteners.
[0061] In some embodiments, as Figure 3 shown, the camera assembly 4 further includes a movement part 43 and a fixing plate 44 for fixing the movement part 43. The movement part 43 is electrically connected to the circuit board 41, and the fixing plate 44 serves as part or all of the first heat conducting member or the second heat conducting member.
[0062] In the embodiment of this application, the material of the fixing plate 44 includes but is not limited to metals with good heat conductivity such as copper, copper alloy, aluminum, and aluminum alloy. The fixing plate 44 can be in contact with the circuit board 41 to conduct the heat generated by the circuit board 41, and one side of the fixing plate 41 can be in contact connection with the inner side of the lens barrel part 12, so as to conduct the heat of the circuit board 41 to the lens barrel part 12 and then to the adapter ring 3. And / or, the other side of the fixing plate 44 can extend in the direction close to the wire harness sleeve 8 and be in contact with the inner housing 211, so as to transfer the heat of the circuit board 41 to the wire harness sleeve 8 connected to the inner housing 211 through the inner housing 211.
[0063] Optionally, the fixing plate 44 can include a first fixing plate 441. The first fixing plate 441 serves as part or all of the first heat conducting member. The first fixing plate 441 is located between the circuit board 41 and the adapter ring 3. The first fixing plate 441 is used to fix the movement part 43 and is used to conduct the heat generated by the circuit board 41 to the adapter ring. Further, the first heat conducting member can include a heat conducting pad 2212. The heat conducting pad 2212 can be arranged between the circuit board 41 and the first fixing plate 441, or between the first fixing plate 441 and the adapter ring 3.
[0064] Optionally, as Figure 3As shown, a partial structure of the first fixing plate 441 is parallel to the circuit board 41, enabling the circuit board 41 to better transfer heat to the first fixing plate 441. Moreover, one side of the first fixing plate 441 close to the lens barrel portion 12 is bent away from the circuit board 41 and contacts the inner side of the lens barrel portion 12, so as to conduct the heat of the circuit board 41 to the adapter ring 3 via the lens barrel portion 12. One side of the heat conduction plate 2211 contacts the circuit board 41, and the other side extends in the direction close to the wire harness sleeve 8 and contacts the inner shell 10, thereby transferring the heat of the circuit board 41 to the wire harness sleeve 8 via the inner shell 10. Wherein, the first fixing plate 441 and the heat conduction plate 2211 may not be connected.
[0065] In some embodiments, the fixing plate 44 is disposed on the circuit board 41, and the movement mechanism portion 43 is fixedly disposed on the fixing plate 44, so that the fixing plate 44 does not contact the main body portion 11, further reducing the probability that the heat generated by the imaging assembly 4 is transferred to the housing 10 through the fixing plate 44 or the first heat conducting member, and further reducing the probability of phenomena such as a relatively high temperature rise in the main body portion 11, thereby further improving the use experience of medical staff and the product performance of the medical handheld camera. Further, as Figure 3 shown, the movement mechanism portion 43 is fixedly disposed on the first fixing plate 441.
[0066] In some embodiments, one side of the first heat conducting member is in contact connection with the circuit board 41, and the other side is in contact connection with one side of the lens barrel portion 12 close to the imaging assembly 4, enabling the heat of the circuit board 41 to be conducted to the first heat conducting member and transferred to the lens barrel portion 12 via the first heat conducting member, then transferred to the adapter ring 3 and conducted to the outside of the medical handheld camera, improving the heat dissipation performance of the medical handheld camera.
[0067] In some embodiments, the circuit board 41 includes a main board 411 and a sensor circuit board 412. The first heat conducting member is disposed between the main board 411 and the adapter ring 3, and the second heat conducting member is inside the housing 10 and extends from the sensor circuit board 412 to the wire harness sleeve 8 located outside the housing 10.
[0068] In the embodiments of the present application, as Figure 3As shown, the sensor circuit board 412 can be arranged perpendicular to the main board 411, so as to make the layout of the sensor circuit board 412 and the main board 411 more reasonable and reduce the volume of the imaging component 4. Further, a processing chip, such as a SoC (System on a Chip) chip, etc., is integrated on the main board 411. The processing chip is used to control the working state of the imaging component, and the processing chip is also used to process the images collected by the imaging component. An image sensor is integrated on the sensor circuit board 412. The image sensor includes, but is not limited to, a CCD (Charged Coupled Device) image sensor, a COMS (Complementary Metal Oxide Semiconductor) image sensor, etc.
[0069] In the embodiment of the present application, the first heat conducting member can transfer the heat of the main board 411 to the adapter ring 3, and the second heat conducting member can transfer the heat of the sensor circuit board 412 to the inner shell 211 and then to the wire harness sleeve 8. So that the heat of the circuit board 41 can be transmitted along different paths, and the heat of the circuit board 41 can be exported more quickly, further improving the heat dissipation performance of the medical camera.
[0070] In the embodiment of the present application, as Figure 3 shown, the first fixing plate 441 is located between the main board 411 and the adapter ring 3, and the first fixing plate 441 is used to conduct the heat of the main board 411 to the adapter ring 3. The heat conducting member 221 is located between the sensor circuit board 412 and the inner shell 211, and the heat conducting member 221 is used to conduct the heat of the sensor circuit board 412 to the inner shell 221 and then to the wire harness sleeve 8. As Figure 3 and Figure 6 shown, the first heat conducting member can include two heat conducting pads 2212. One heat conducting pad 2212 is located between the first fixing plate 441 and the main board 411, and the other heat conducting pad 2212 is located between the first fixing plate 411 and the inner side wall of the lens barrel portion 12. The heat conducting member 221 can also include two heat conducting pads 2212. One heat conducting pad 2212 is located between the sensor circuit board 412 and the heat conducting plate 2211, and the other heat conducting pad 2212 is located between the heat conducting plate 2211 and the inner shell 211.

Or, the fixing plate 44 includes a second fixing plate for fixing the sensor circuit board 412, and the second fixing plate can be a part or all of the second heat conducting member.
[0072] Further, as Figure 3 and Figure 5As shown, the camera assembly 4 may further include a fixing member 40, which is fixedly connected to the movement part 43. The fixing member 40 is sleeved on the movement part 43, and a fifth through hole 404 is formed in the fixing member 40.
