Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular, to an umbrella-shaped lens capsule endoscope. Background Art

[0002] With the increasing degree of social aging, the quality of life of the elderly has attracted much attention. Age-related cataract is an important cause of vision decline in the elderly, and in severe cases, it is even a blinding disease. At present, cataract surgery and intraocular lens replacement surgery are well-developed surgical procedures in ophthalmology. Through phacoemulsification cataract extraction + intraocular lens implantation in the lens capsule, the cloudy lens (cortex or nucleus) can be removed, effectively improving the transparency of the eye refractive medium, thereby improving the patient's vision. However, due to individual differences among patients and the varying proficiency of surgeons, the residual lens epithelial cells during the operation may increase the incidence of posterior capsule opacification, that is, the residual lens epithelial cells continue to proliferate, causing visual field obstruction and vision decline. If re-operation or laser treatment is required, it will bring more psychological pressure and economic burden to cataract patients. Therefore, cataract surgeons strive to completely remove the patient's own lens cortex during the operation, especially the cortex at the equator of the lens, to reduce the occurrence of posterior capsule opacification.

[0003] Since cataract surgery is a microsurgery, the operating range of ophthalmologists is narrow and the surgical field of view is limited. At present, cataract surgery has the following difficulties: First, the negative suction of the phacoemulsification probe is relatively strong, and it is difficult to control the distance during the operation to only remove the cortex while ensuring the integrity of the lens posterior capsule (rupture of the lens posterior capsule during cataract surgery is a serious complication); Second, since the capsule at the equator of the lens is a blind area of the surgical field of view, it is difficult to safely and completely remove the lens cortex without a clear field of view; Third, professional eye endoscope equipment is expensive, and only a few hospitals have professional equipment to assist the operation.

[0004] Therefore, we make improvements in this regard and propose an umbrella-shaped lens capsule endoscope. Summary of the Invention

[0027] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0028] Embodiment 1 Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 10 For an umbrella-shaped lens capsule endoscope, its reflection mechanism 4 includes a reflector 401.

A plurality of slots are equidistantly opened on the opposite sides of the top of the positioning ring 2 and the bottom of the first limiting ring 3. An arc-shaped rod 402 is fixedly arranged through between the plurality of slots. The reflector 401 is made of an elastic and retractable material, and its front surface is very smooth, capable of realizing specular reflection, and can be unfolded and contracted to different degrees on the umbrella surface. Due to the strong elasticity of the reflector 401, the reflective surface of the endoscope can be fully unfolded at any position, realizing perfect specular reflection.

[0029] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 10, An umbrella-shaped lens capsule endoscope, wherein the reflection mechanism 4 further includes a plurality of first umbrella rods 403, and the plurality of first umbrella rods 403 respectively correspond to the slots on the first limiting ring 3.

Through the movable shaft 405, the first umbrella rod 403 is movably connected to the second umbrella rod 404. The reflector 401 is installed on the positioning ring 2 and a plurality of second umbrella rods 404.

[0030] Embodiment 2 The umbrella-shaped lens capsule endoscope provided in Embodiment 1 is further optimized. Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, the driving mechanism 5 includes an airbag 501. The airbag 501 is arranged on one side of the connecting column 1. A rotating shaft 502 is fixedly provided on one side of the lower interface of the airbag 501. One end of the rotating shaft 502 is rotatably connected to a connecting block 503. The damping between the rotating shaft 502 and the connecting block 503 is relatively large, and the top end of the connecting column 1 is fixedly connected to the bottom end of the connecting block 503. Through the rotating shaft 502, the connecting block 503 can be rotated, so that the connecting column 1 drives the reflection mechanism 4 to rotate, avoiding the reflection mechanism 4 from hindering the postoperative cleaning and drainage.

[0031] Furthermore, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, the driving mechanism 5 further includes a connecting head 504. A first thread groove matching the upper interface of the airbag 501 is formed in the bottom end of the connecting head 504. Through this setting, the connecting head 504 can be removed and cleaning liquid can be filled into the airbag 501. A sealing disc 505 is arranged at the top of the upper interface, and the top end of the sealing disc 505 is in contact with the inner wall of the upper interface. Through the sealing disc 505, the sealing between the connecting head 504 and the airbag 501 is realized. A first connecting pipe 506 is communicated with one side of the top end of the connecting head 504. A first gas one-way valve 507 is fixedly arranged in the first connecting pipe 506. The air outlet of the first gas one-way valve 507 faces the airbag 501. Through the first gas one-way valve 507, the outside gas can enter the airbag 501.

[0032] Example 3 The umbrella-shaped lens capsule endoscope provided in Example 1 or 2 is further optimized. Specifically, as Figures 1-2 shown, the displacement assembly 6 is composed of a first displacement mechanism 8 and a second displacement mechanism 9.

[0033] Furthermore, as Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 8 shown, the first displacement mechanism 8 includes a second connecting pipe 801. The top end of the second connecting pipe 801 is threadedly connected to the lower interface of the airbag 501, and on the other side of the top end of the connector 504, a second thread groove matching the second connecting pipe 801 is provided. Through the second thread groove, the connector 504 and the second connecting pipe 801 can be fixedly sealed. A second gas one-way valve 802 is fixedly provided in the second connecting pipe 801, and the air inlet of the second gas one-way valve 802 faces upward. By squeezing the airbag 501, the gas enters through the second gas one-way valve 802. The bottom end of the second connecting pipe 801 communicates with a cylinder body 803, and a piston 804 is provided at the top of the cylinder body 803.

[0034] Furthermore, as Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 8 shown, the first displacement mechanism 8 further includes a round block 805. The bottom end of the round block 805 is fixedly connected to the bottom end of the piston 804. Both sides of the round block 805 are penetrated by a limiting rod 806. The top of the inner side of the limiting rod 806 is convexly arranged, and the convex part is penetrated and connected with the round block 805. Limiting grooves are provided on both sides inside the round block 805, and a T-shaped rod 807 is arranged in the limiting groove. One end of the T-shaped rod 807 penetrates out of the round block 805 and is fixedly connected to the limiting rod 806. Card slots matching the convex parts are provided at the bottom ends of both sides of the cylinder body 803.

[0035] Example 4 On the basis of the umbrella-shaped lens capsule endoscope provided in the above-mentioned embodiments, further optimization is carried out. As Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 8 and Figure 9As shown in the figure, the second displacement mechanism 9 includes a drainage tube 901. A third threaded groove matching the drainage tube 901 and the first connecting tube 506 is provided in the middle of the bottom end of the round block 805. The top end of the drainage tube 901 is also threadedly arranged to match the lower interface of the airbag 501. A fourth threaded groove is provided at the bottom inside the drainage tube 901. A spray tube 902 is threadedly connected to the fourth threaded groove. A plurality of spray holes are provided at the bottom end of the spray tube 902, and the inner diameter of the spray tube 902 becomes smaller closer to the spray holes. Since the inner diameter of the spray tube 902 becomes smaller closer to the spray holes, the pressure received by the cleaning liquid when passing through the spray holes is large enough, so that the spraying range of the cleaning liquid is wider or can be in a mist shape.

[0036] Further, as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 9 shown in the figure, the connecting part 7 includes a second limiting ring 701. The second limiting ring 701 is fixedly installed on the connecting column 1. A connecting rod 702 is fixedly arranged between the second limiting ring 701 and the first limiting ring 3. A positioning block 703 is fixedly arranged on one side of the second limiting ring 701. An arc-shaped block 704 is fixedly arranged on one side of the positioning block 703. A clamping block 705 is fixedly arranged at the bottom on one side of the drainage tube 901, and an arc-shaped clamping groove matching the arc-shaped block 704 is provided in the middle of the clamping block 705.

[0037] The usage process of the umbrella-shaped lens capsule endoscope provided by the present invention is as follows: When cataract surgery is required, operate the endoscope and manually squeeze the airbag 501, so that the gas in the airbag 501 continuously squeezes into the cylinder body 803 through the second gas one-way valve 802, thereby increasing the pressure in the cylinder body 803 continuously. Further, it can push the piston 804 to drive the round block 805 to move, so that the drainage tube 901 moves. Cooperating with the clamping block 705 and the arc-shaped block 704, the drainage tube 901 drives the second limiting ring 701 to move. Cooperating with the connecting rod 702, the first limiting ring 3 moves. As the first limiting ring 3 moves, through the arc-shaped rod 402 and the movable shaft 405, the first umbrella rod 403 pushes up the second umbrella rod 404. As several second umbrella rods 404 are pushed up, the reflecting member 401 is propped up to form a fan surface. Through this operation, the umbrella surface can be unfolded and contracted to different degrees, and a clear view of the residual lens cortex in the blind area is provided through the specular reflection of light, assisting the ophthalmologist to safely and completely remove the lens cortex and reducing the occurrence of posterior capsular cataract in patients. After the operation, when cleaning is required, through the rotating shaft 502, the connecting block 503 can drive the connecting column 1 to rotate, so that the arc-shaped block 704 rotates out of the clamping block 705. Rotate the cylinder body 803 to separate the second connecting pipe 801 from the airbag 501, and the displacement assembly 6 can be removed. Pull the drainage tube 901 to pull out the piston 804. Rotate the drainage tube 901 to separate the round block 805 from the drainage tube 901. Threadedly connect the drainage tube 901 to the lower interface of the airbag 501 to fix the drainage tube 901 on the airbag 501. Rotate the connecting head 504 to separate the connecting head 504 from the upper interface of the airbag 501, take out the sealing disc 505, and add cleaning liquid into the airbag 501. Rotate the connecting head 504 to fix the connecting head 504 to the airbag 501. Rotate the second connecting pipe 801, and the second connecting pipe 801 is fixed on the connecting head 504 to make the cylinder body 803 communicate with the connecting head 504. At this time, the orientation of the second gas one-way valve 802 changes, the air inlet of the second gas one-way valve 802 faces downward, and the air outlet faces upward. Insert the piston 804 into the cylinder body 803. Through the T-shaped rod 807, the limiting rod 806 can be pulled, and after pulling out the limiting rod 806, align it with the card slot and move the limiting rod 806 so that the protrusion is engaged with the card slot to fix the piston 804, thereby sealing the cylinder body 803. At this time, squeeze the airbag 501. Cooperating with the first gas one-way valve 507, the cleaning liquid can enter the spray pipe 902 through the drainage tube 901. Since the inner diameter of the spray pipe 902 becomes smaller closer to the spray hole, the cleaning liquid is sprayed for cleaning. After cleaning, take out the piston 804 from the cylinder body 803 and rotate the piston 804 to fix the round block 805 to the first connecting pipe 506 to seal the first connecting pipe 506. Rotate the spray pipe 902 to take out the spray pipe 902. Manually squeeze the airbag 501, and under the action of the second gas one-way valve 802, the waste liquid enters the airbag 501 through the drainage tube 901 to achieve drainage.
