Description

Technical Field

[0001] The present application relates to the technical field of endoscopes, and in particular to an endoscope host and an endoscope system. Background Art

[0002] The endoscope system is a commonly used medical device. When in use, the endoscope enters the patient's body through a natural orifice in the human body or an incision formed during surgery. After the endoscope is introduced into the organ to be examined, the doctor can directly view the image of the lesion in the relevant part on the display screen of the host computer, thereby making a medical diagnosis.

[0003] To obtain clear images of lesions and improve diagnostic accuracy, operators must adjust image quality and position by pressing touch controls on the display to achieve the best possible image. Currently, the main unit's display is typically mounted on the main unit's housing, resulting in an unstable mounting structure. Pressing touch controls or adjusting the display's angle can cause the display to shake or shimmy, affecting user operation and image quality. Utility Model Content

[0004] Based on this, it is necessary to provide an endoscope host and an endoscope system to address the problem of how to improve the installation stability of the display screen.

[0005] In one aspect, the present application provides an endoscope host, comprising:

[0006] Host housing;

[0007] a substrate, the substrate being fixed to the host housing, wherein the strength and rigidity of the substrate are greater than the strength and rigidity of the host housing;

[0008] a mounting bracket connected to the substrate; and

[0009] A display screen is connected to the mounting bracket.

[0010] The technical solution is further described below:

[0011] In one embodiment, the substrate is a metal plate.

[0012] In one embodiment, the projection area of ​​the substrate in the height direction of the endoscope main body is S1; the projection area of ​​the main body shell in the height direction of the endoscope main body is S2, wherein S1 ≥ 90% S2.

[0013] In one embodiment, the host shell includes an upper shell and a lower shell that are relatively arranged in the height direction of the endoscope host, and the upper shell and the lower shell together enclose a accommodating cavity. The substrate is arranged in the accommodating cavity and connected to the lower shell. The upper shell is provided with an avoidance opening that communicates with the accommodating cavity, one end of the mounting bracket is connected to the substrate, and the other end of the mounting bracket passes through the avoidance opening and is connected to the display screen.

[0014] In one embodiment, the base plate is provided with a positioning hole, the lower shell is provided with a positioning post protruding toward the upper shell, and the positioning post is inserted into the positioning hole.

[0015] In one embodiment, the endoscope host further includes a limiting gasket and a connecting piece, wherein the limiting gasket abuts against a side of the base plate facing the upper shell, and the connecting piece passes through the limiting gasket and is threadedly connected to the positioning column.

[0016] In one embodiment, the lower shell is further provided with a reinforcing rib protruding toward the upper shell, and the reinforcing rib abuts against a side of the base plate facing away from the upper shell.

[0017] In one embodiment, the mounting bracket comprises:

[0018] a fixing bracket connected to the base plate;

[0019] a rotating shaft, the rotating shaft being fixedly connected to the fixing bracket; and

[0020] A rotating bracket is rotatably connected to the rotating shaft and is connected to the display screen.

[0021] In one embodiment, the rotating bracket is rotatably mounted on the rotating shaft, and the rotating shaft anti-loosening structure also includes a limit block plate, a friction gasket and a locking nut. The limit block plate is fixed to the rotating shaft and abuts against one side of the rotating bracket, the friction gasket is mounted on the rotating shaft and abuts against the other side of the rotating bracket, and the locking nut is threadedly connected to the rotating shaft and abuts against the side of the friction gasket facing away from the rotating bracket.

[0022] On the other hand, the present application also provides an endoscope system, including the above-mentioned endoscope host.

[0023] In the above-mentioned endoscope host and endoscope system, a substrate is provided on the host housing, a mounting bracket is connected to the substrate, and a display screen is mounted via the mounting bracket. Thus, the torque generated when pressing or rotating the display screen can be transmitted to the substrate via the mounting bracket, and then dispersed to the host housing by the substrate. Since the strength and rigidity of the substrate are greater than the strength and rigidity of the host housing, the strength and rigidity of the host housing can be reinforced, thereby improving the connection stability with the mounting bracket, thereby improving the installation stability of the display screen, and avoiding the display screen from shaking or avoiding when pressing the touch items of the display screen or adjusting the angle of the display screen. At the same time, by adding the substrate to the host housing, the overall weight of the endoscope host can be increased, which can effectively reduce the displacement or overturning of the endoscope host when pressing the touch items of the display screen or adjusting the angle of the display screen, further improving the stability of the endoscope host.

[0040] As previously mentioned, in conventional endoscope systems, the display screen 40 is typically mounted directly to the main housing 10 via a bracket. However, the main housing 10 is typically made of engineering plastic, which lacks the strength and rigidity to fully withstand the torque generated by pressing or rotating the display screen 40. This can cause the display screen 40 to shake or shimmy, affecting user operation and image quality. Furthermore, the contact area between the bracket and the main housing 10 is typically small. When pressing or rotating the display screen 40, stress concentration easily forms at the connection between the bracket and the main housing 10, potentially tearing the main housing 10.

[0041] Based on this, an embodiment of the present application provides an endoscope host, specifically, see Figure 1 as well as Figure 2The endoscope main unit of one embodiment comprises a main unit housing 10, a base plate 20, a mounting bracket 30, and a display screen 40. The main unit housing 10 is used to mount the main unit's electronic components, such as the motherboard. The base plate 20 is mounted on the main unit housing 10 and has greater strength and rigidity than the main unit housing 10. The mounting bracket 30 is connected to the base plate 20, and the display screen 40 is connected to the mounting bracket 30.

[0042] The endoscope mainframe is provided with a base plate 20 on the mainframe housing 10, a mounting bracket 30 is connected to the base plate 20, and a display screen 40 is mounted via the mounting bracket 30. Thus, the torque generated when pressing or rotating the display screen 40 can be transmitted to the base plate 20 via the mounting bracket 30, and then dispersed by the base plate 20 to the mainframe housing 10. Since the strength and rigidity of the base plate 20 are greater than those of the mainframe housing 10, the strength and rigidity of the mainframe housing 10 can be reinforced, thereby improving the connection stability with the mounting bracket 30 and the installation stability of the display screen 40. This prevents the display screen 40 from shaking or avoiding when pressing touch items on the display screen 40 or adjusting the angle of the display screen 40. Furthermore, by adding the base plate 20 to the mainframe housing 10, the overall weight of the endoscope mainframe can be increased, effectively reducing the displacement or overturning of the endoscope mainframe when pressing touch items on the display screen 40 or adjusting the angle of the display screen 40, further improving the stability of the endoscope mainframe.

[0043] Optionally, in one embodiment, the substrate 20 is a metal plate. Exemplarily, the substrate 20 is a stainless steel plate, which effectively ensures the structural strength and rigidity of the substrate 20, thereby ensuring the secure connection between the substrate 20 and the mounting bracket 30 and improving the installation stability of the display screen 40. Furthermore, the metal substrate 20 can significantly increase the overall weight of the main unit, thereby improving the placement stability of the endoscope main unit. It is understood that the substrate 20 can also be made of other high-strength and high-rigidity materials, as long as the strength and rigidity of the substrate 20 are greater than those of the main unit housing 10, and this is not a limitation here.

[0044] See also Figure 2 In one embodiment, the projected area of ​​the substrate 20 in the height direction of the endoscope mainframe is S1; the projected area of ​​the mainframe housing 10 in the height direction of the endoscope mainframe is S2, where S1 ≥ 90% S2. For example, S1 accounts for 90% of S2, thereby increasing the contact area between the substrate 20 and the mainframe housing 10. This allows the substrate 20 to evenly distribute the torque transmitted by the mounting bracket 30 to various parts of the mainframe housing 10, avoiding stress concentration and thus preventing the mainframe housing 10 from being pulled or torn. Furthermore, the larger substrate 20 can further increase the overall weight of the mainframe, thereby further improving the stability of the display screen 40.

[0045] See also Figure 1 Optionally, in one embodiment, the main body housing 10 includes an upper housing 12 and a lower housing 11 disposed opposite each other in the height direction of the endoscope main body. The upper housing 12 and the lower housing 11 together enclose a receiving cavity 13. The substrate 20 is disposed in the receiving cavity 13 and connected to the lower housing 11. Exemplarily, the lower housing 11 has a bottom wall disposed opposite the upper housing 12, and the substrate 20 is fixed to the bottom wall. Furthermore, the upper housing 12 defines a clearance opening 121 that communicates with the receiving cavity 13. One end of the mounting bracket 30 is connected to the substrate 20, and the other end of the mounting bracket 30 extends through the clearance opening 121 and connects to the display screen 40. Exemplarily, by attaching the substrate 20 to the lower housing 11, the center of gravity of the substrate 20 is lowered, thereby lowering the overall center of gravity of the main body, avoiding the problem of the endoscope main body being easily overturned due to an excessively high center of gravity, thereby improving the stability of the endoscope main body. Furthermore, the substrate 20 is disposed in the receiving cavity 13, which can conceal the substrate 20 and ensure the consistency of the appearance of the main body housing 10.

[0046] Furthermore, the base plate 20 is provided with a positioning hole. Figure 3 The lower shell 11 is provided with a positioning post 111 protruding toward the upper shell 12, and the positioning post 111 is inserted into the positioning hole. In this way, the accuracy of the installation position of the substrate 20 can be guaranteed. Figure 5 The endoscope mainframe further includes a retaining washer 52 and a connector 51. The retaining washer 52 abuts the side of the base plate 20 facing the upper housing 12. The connector 51 passes through the retaining washer 52 and is threadedly connected to the positioning post 111. Exemplarily, the connector 51 is a screw. This securely retains the base plate 20 on the positioning post 111, further improving the stability of the connection between the base plate 20 and the mainframe housing 10.

[0047] Continue to see Figure 5 Optionally, the lower housing 11 is further provided with a reinforcing rib 112 that protrudes toward the upper housing 12. The reinforcing rib 112 abuts against the side of the substrate 20 facing away from the upper housing 12. Exemplarily, there are multiple reinforcing ribs 112, which are intersectingly arranged. Thus, providing the reinforcing ribs 112 on the lower housing 11 not only increases the structural strength of the lower housing 11, thereby improving the installation stability of the display screen 40, but also supports the substrate 20, thereby improving the connection stability between the substrate 20 and the lower housing 11, further improving the installation stability of the display screen 40.

[0048] See also Figure 2Optionally, in one embodiment, the mounting bracket 30 includes a fixed bracket 31, a rotating shaft 32 and a rotating bracket 33, wherein the fixed bracket 31 is connected to the substrate 20. The rotating shaft 32 is fixedly connected to the fixed bracket 31. The rotating bracket 33 is rotatably connected to the rotating shaft 32, and the rotating bracket 33 is connected to the display screen 40. In this way, the angle of the display screen 40 can be adjusted by flipping the rotating bracket 33 to obtain the best image effect. Exemplarily, the number of the rotating shafts 32 is two, and the two rotating shafts 32 are symmetrically arranged. Specifically, the fixed bracket 31 is provided with two support members, and the two support members are connected to the two rotating shafts 32 in a one-to-one correspondence, and the rotating bracket is provided with two legs, and the two legs are rotatably connected to the two rotating brackets in a one-to-one correspondence, thereby improving the stability of the display screen 40 when it rotates.

[0049] See also Figure 4 The rotating bracket 33 is rotatably mounted on the rotating shaft 32. The anti-loosening structure of the rotating shaft 32 also includes a stopper 71, a friction washer 72, and a locking nut 73. The stopper 71 is fixed to the rotating shaft 32 and abuts one side of the rotating bracket 33. The friction washer 72 is mounted on the rotating shaft 32 and abuts the other side of the rotating bracket 33. The locking nut 73 is threadedly connected to the rotating shaft 32 and abuts the side of the friction washer 72 facing away from the rotating bracket 33. The locking nut 73 presses the friction washer 72 against the rotating bracket 33, and the friction between the friction washer 72 and the rotating bracket 33 allows the display screen 40 to hover at any angle. To adjust the angle of the display screen 40, the display screen 40 or the rotating bracket 33 is rotated. When the force applied to the display screen 40 or the rotating bracket 33 exceeds the friction between the friction washer 72 and the rotating bracket 33, the display screen 40 can be rotated, thereby adjusting the angle of the display screen 40. The exemplary number of friction pads 72 is multiple, and the multiple friction pads 72 are arranged along the axial direction of the rotating shaft 32 , thereby improving the stability of locking the rotating bracket 33 .

[0050] Another embodiment of the present application further provides an endoscope system. Specifically, the endoscope system of one embodiment includes the endoscope host described above. Furthermore, the endoscope system also includes an endoscope body, which is electrically connected to the endoscope host.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
