Description

Technical Field

[0001] The utility model relates to the technical field of endoscope assembly, in particular to a test card installation component and an endoscope centering device. Background Art

[0002] Endoscope is a common medical device that can be inserted into the human body to collect images of lesions. The imaging module of existing endoscopes usually includes a mirror rod and a lens module, and the lens module of some endoscopes that can form a display image usually includes a lens and a sensor. When assembling such endoscopes, it is necessary to keep the lens concentric with the vertical axis of the sensor surface so that the lens can obtain the best shooting effect. Therefore, when installing the sensor, it is necessary to use specific assembly equipment for centering.

[0003] The existing assembly equipment for assembling lens modules with mirror rods usually adopts a mechanical limit method for installation, directly limits the sensor through the limit hole, and fixes the sensor and the lens. Since there is a gap when the limit hole and the sensor are matched, the difference in the feedback on the optical image is relatively large, and the position of the sensor cannot be slightly adjusted, and the final imaging effect is poor. In addition, during testing, the test card installation component is usually set at the insertion end of the mirror rod. For mirror rods of different lengths, it is impossible to ensure that the distance between each pass and the test card is consistent, and since the insertion ends of some mirror rods have different degrees of bending angles, the test card installation component cannot keep the test surface flush with the mirror surface of the mirror rod.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0034] Based on the problem that the existing mechanically limited assembly equipment cannot accurately adjust the center and the existing test card installation assembly cannot adapt to the mirror rods of endoscopes with different lengths and bending angles, the present application provides a test card installation assembly and an endoscope centering device. The endoscope centering device can move multiple times in one clamping, can center the lens module of the endoscope at one time, and has higher centering accuracy. The test card installation assembly can adapt to the mirror rods of endoscopes with different lengths and bending angles.

[0035] For details, please refer to Figures 1 to 4 The present application provides a test card installation assembly 10, which is used to be set on the mirror rod 51 of the endoscope when testing the endoscope. The test card installation part 11 may include a test card installation part 11 and a sliding part 12. The test card installation part 11 is used to install the test card. The sliding part 12 is rotatably connected to the test card installation part 11. The sliding part 12 has a sliding cavity 121, and the sliding cavity 121 is used to be slidably sleeved on the mirror rod 51 of the endoscope.

[0036] It is understandable that the test card mounting portion 11 can slide up and down along the mirror rod 51 of the endoscope through the sliding cavity 121, so as to ensure that the distance between each mirror rod 51 and the optical test card assembly is consistent, thereby solving the problem of inaccurate distance between the lens 52 assembly and the test card caused by mirror rods 51 of different lengths. The sliding portion 12 can rotate relative to the test card mounting portion 11, so that the test surface of the test card is always kept flush with the mirror surface of the mirror rod 51, so that mirror rods 51 with different bending angles can be tested.

[0037] More specifically, if Figure 2 and Figure 3 As shown, in one embodiment, the test card mounting portion 11 includes a fixed bracket 111 rotatably connected to the sliding portion 12, a test card mounting plate 112 mounted on the fixed bracket 111, and a light-emitting component 113 detachably mounted on the fixed bracket 111. The light-emitting component 113 can emit illumination light to provide a light source for the test card, so that the mirror rod 51 can collect the image of the test card and transmit it to the lens module. When assembling the test card, the light-emitting component 113 can be removed from the fixed bracket 111, and then the test card mounting plate 112 can be removed from the fixed bracket 111. After the test card is installed on the fixed bracket 111, the test card mounting plate 112 and the light-emitting component 113 are reinstalled on the fixed bracket 111. The test card mounting plate 112 can be fixed to the fixed bracket 111 by the light-emitting component 113.

[0038] Preferably, if Figure 2 and Figure 3 As shown, in one embodiment, the fixed bracket 111 includes a bracket body 1111 and a connecting plate 1112 fixed to the bracket body 1111, the light emitting assembly 113 is installed on the bracket body 1111, the sliding portion 12 is rotatably connected to the connecting plate 1112, an adjustment cavity 1113 is provided between the bracket body 1111 and the connecting plate 1112, the sliding cavity 121 is connected to the adjustment cavity 1113, and the bracket body 1111 has a test port 1114 connected to the adjustment cavity 1113. The illumination light emitted by the light emitting assembly 113 is collected by the mirror rod 51 through the test port 1114 after passing through the test card. The adjustment cavity 1113 is used to accommodate the insertion end of the mirror rod 51. When the mirror rod 51 slides in the sliding cavity 121, the insertion end of the mirror rod 51 can be received in the adjustment cavity 1113, so that the test card installation assembly 10 has an adjustment space.

[0039] Preferably, if Figure 2 and Figure 3As shown, in one embodiment, the fixed bracket 111 further includes a plurality of limiting posts 1115 protruding from the bracket body 1111, and the test card mounting plate 112 has a plurality of limiting portions 1121, which are respectively arranged between the limiting posts 1115. In this way, the limiting posts 1115 cooperate with the limiting portions 1121 to limit the test card on the fixed bracket 111.

[0040] For details, please refer to Figures 1 to 4 The endoscope centering device is used to adjust the endoscope. The endoscope centering device may include an adjustment component 20, a fixing component 30, a test card mounting component 10 as described above, and a control component. The adjustment component 20 includes a degree of freedom platform 21 and a sensor fixture 22 fixed on the degree of freedom platform 21, and the sensor fixture 22 is used to clamp the sensor 54 of the endoscope. The fixing component 30 is arranged above the degree of freedom platform 21, and is used to fix the mirror rod 51 of the endoscope and the housing of the lens 52 of the endoscope. The test card mounting component 10 is adjustably arranged above the fixing component 30. The control component is electrically connected to the test card mounting component 10, and is used to receive the test data of the sensor 54 of the endoscope; the control component is electrically connected to the degree of freedom platform 21, and is used to control the degree of freedom platform 21 to drive the sensor fixture 22 to move.

[0041] It can be understood that when the endoscope centering device is used to adjust the endoscope, the outer shell of the mirror rod 51 and the lens 52 of the endoscope is first fixed by the fixing component 30. Then, by setting the test card mounting component 10 at the insertion end of the mirror rod 51, the distance between the test component and the mirror rod 51 is adjusted to the required distance by sliding the test component; and by rotating the test component, the test surface of the test component is flush with the mirror surface of the mirror rod 51. Then the sensor 54 is clamped by the sensor fixture 22. Finally, the control component controls the movement of the degree of freedom platform 21 according to the received test data, so that the sensor 54 moves to a position concentric with the lens 53 and the mirror rod 51. The endoscope centering device simulates the actual test imaging process of the endoscope, can be moved multiple times in one clamping, can align the lens module of the endoscope at one time, and has higher centering accuracy.

[0042] Alternatively, if Figure 1 and Figure 4As shown, in one embodiment, the fixing assembly 30 includes a fixing back plate 31, a fixing abutment 32 fixed to the fixing back plate 31, a lens abutment 33 movably abutted against the fixing abutment 32, and a mirror rod abutment 34 movably abutted against the fixing abutment 32, the lens abutment 33 is used to cooperate with the fixing abutment 32 to clamp the housing of the lens 52 of the endoscope, and the mirror rod abutment 34 is used to cooperate with the fixing abutment 32 to clamp the mirror rod 51 of the endoscope. In other words, the mirror rod abutment 34 and the lens abutment 33 can be detached from or abutted against the fixed abutment 32. When the mirror rod abutment 34 and the lens abutment 33 are detached from the fixed abutment 32, the lens 52 and the mirror rod 51 can be loaded or removed. When the mirror rod abutment 34 and the lens abutment 33 abut against the fixed abutment 32, the mirror rod abutment 34 and the lens abutment 33 can clamp the lens 52 and the mirror rod 51.

[0043] Alternatively, if Figure 1 and Figure 4 As shown, in one embodiment, the fixed abutment 32 includes a lens fixing portion 321 fixed to the fixed back plate 31, the lens fixing portion 321 has a first fixing groove (not shown) on one side close to the lens abutment 33, and the lens abutment 33 has a second fixing groove (not shown) on one side close to the lens fixing portion 321, when the lens abutment 33 abuts against the lens fixing portion 321, the second fixing groove is used to cooperate with the first fixing groove to clamp the housing of the lens 52 of the endoscope. The first fixing groove and the second fixing groove can fit with the housing of the lens 52. The first fixing groove and the second fixing groove can have the same shape as the cross section of the housing of the lens 52 after being combined.

[0044] Optionally, in one embodiment, the fixed abutment 32 includes a mirror rod fixing portion 322 located above the lens fixing portion 321 and a connecting portion 323 connecting the mirror rod fixing portion 322 and the lens fixing portion 321, the mirror rod fixing portion 322 has a third fixing groove (not shown in the figure), and the mirror rod abutment 34 has a fourth fixing groove (not shown in the figure), when the mirror rod abutment 34 abuts against the mirror rod fixing portion 322, the fourth fixing groove is used to cooperate with the third fixing groove to clamp the mirror rod 51 of the endoscope. The third fixing groove and the fourth fixing groove can fit with the outer shell of the lens 52. The third fixing groove and the fourth fixing groove can have the same shape as the cross section of the outer shell of the lens 52 after being combined.

[0045] Preferably, if Figure 1 and Figure 4As shown, in one embodiment, the fixed abutment 32 includes a step portion 324 extending from the lens fixing portion 321 to the bottom of the lens abutment 33. When the lens abutment 33 abuts against the lens fixing portion 321, the step portion 324 is supported under the lens abutment 33. The step portion 324 can cooperate with the lens abutment 33 to more firmly clamp the housing of the lens 52, thereby preventing the deviation of the centering result caused by the offset during the movement of the freedom platform 21.

[0046] Furthermore, in one embodiment, the endoscope centering device further includes a light curing component 40, which is fixed to the freedom platform 21 and is used to cure the glue between the endoscope lens 53 and the endoscope sensor 54. The light curing component 40 can be a UV glue curing lamp.

[0047] The technical features of the above embodiment can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiment 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.

[0048] The above embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
