[0004] The above patent solves the problem that although the traditional eyelid expansion device can fix the patient's head and adjust the position of the expansion mechanism, both require manual single adjustment, which not only has low work efficiency but also poor accuracy; but at the same time of eyelid expansion, it is impossible to relax the patient, relieve the patient's tension, and thus improve the patient's comfort. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an ophthalmic clinical eyelid expansion device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: An ophthalmic clinical eyelid expansion and support device comprises a workbench body and a detection unit, wherein the upper end surface of the workbench body is provided with the detection unit, wherein the detection unit comprises an auxiliary mechanism and a relief mechanism installed on one side of the auxiliary mechanism, wherein an adjustment mechanism is laterally arranged on the side end surface of the relief mechanism, and an expansion and support mechanism is slidably arranged on the lower end surface of the adjustment mechanism; The expansion mechanism includes a sliding block and a mounting plate installed at the bottom of the sliding block, an assembly ring is installed at the bottom of the mounting plate, the lower end surface of the assembly ring is connected in series with the detection tube through an assembly vertical rod, and the outer end of the connecting tube is annularly provided with an assembly vertical rod.

[0007] Preferably, the expansion mechanism also includes a control cylinder arranged at the bottom of the detection cylinder, the outer ring array of the control cylinder is provided with an outrigger rod, the lower end surface of the outrigger rod is installed with a pressing block, and the operator adjusts the expansion mechanism as a whole using the opening groove of the sliding groove as a path, and in the process of adjusting the position of the expansion mechanism, the lower end surface of the control cylinder can be adjusted to a position just above the patient's eyeball, thereby improving the stability of the patient's eye during the detection process and reducing the detection error caused by eye movement. At this time, the pressing block laterally supported by the outrigger rod expands the patient's eye area outward in all directions Skin, this support can keep the skin around the eyes stable and effectively open the upper and lower eyelids. When the sliding block is pushed downward by an external drive motor, the sliding block pushes the mounting plate and the assembly ring downward to move. When the bottoms of the four pressing blocks are all in a supporting state, the upper and lower eyelids of the eyes will be supported and opened. The control tube can be locked just above the patient's pupil, so that the patient's pupil, iris and other parts of the eyeball can be detected using the detection device arranged in the inner cavity of the detection tube. The patient's pupil position can be accurately and stably located, providing convenience for subsequent eye detection.

[0008] Preferably, the auxiliary mechanism includes a supporting vertical rod and an assembly table installed at the top position of the supporting vertical rod, the upper end surface of the assembly table is provided with a placement frame, a feeding hole is formed through the middle position of the rear end surface of the placement frame, and an exhaust hole is formed in the middle position of the upper end surface of the assembly table, a discharge hole is provided on one side of the discharge hole, and an inclined slide is arranged at an angle in the inner cavity of the discharge hole, so that an operator can guide the warm airflow into the inner cavity of the placement frame from the outside to the inside, and guide the warm airflow entering the inner cavity of the placement frame to be discharged downward through the exhaust hole and the discharge hole to ensure good airflow and avoid airflow stagnation. The warm airflow discharged from multiple channels hits the upper end surface of the table from top to bottom and slides downward to the inner cavity of the placement rack, thereby realizing a large area of ​​hot airflow distribution. Because the inner cavity walls on both sides of the placement rack can block the warm airflow, the warm airflow can temporarily surround the inner cavity of the placement rack, so that the head of the tested patient can be surrounded by the warm airflow, which can relieve the patient's tension and improve the patient's comfort.

[0009] Preferably, the relief mechanism includes an inner support frame and a first support frame installed on the upper end surface of the inner support frame, a hand-held frame is vertically arranged on the lower end surface of the inner support frame, and the side end surface of the inner support frame is inclinedly connected to the lower slide, so that the patient's arm can penetrate into the inner cavity of the built-in groove, so that the patient's palm can hold the outer ring of the hand-held frame in the inner cavity of the built-in groove, so that the patient can use force with his hands during the eye test to distract his attention, avoiding the situation where the eyes are too tense during the test and causing lack of energy.

[0010] Preferably, the adjustment mechanism includes a second support frame and a track arranged inside the second support frame, a sliding groove is arranged on the lower end surface of the track, and the other end of the track is attached to the inner end surface of the first support frame.

[0012] Preferably, the workbench body includes a built-in groove opened in the inner cavity, the upper end surface of the built-in groove is paved with a table top, the inner cavity of the table top opens a built-in cavity, and the side end surface of the table top is laterally provided with a placement rack, and the entire device is placed on the operating table top. At this time, the patient who needs to be examined lies flat on the operating table top with his head placed in the inner cavity of the placement rack. The patient's face is facing upward at this time, and it is ensured that one side of the ear can fit into the inner cavity wall of the placement rack to avoid the patient's eyes colliding with the device components due to shaking during the test.

[0013] Preferably, one side of the built-in cavity is set as a double-opening structure, and the other side of the built-in cavity is set as a single-opening structure.

[0014] Preferably, the bottom of the inclined slide is fitted to the single-opening outer end surface of the built-in cavity, and the upper end surface of the lower slide is transversely fitted to the single-opening inner end surface of the built-in cavity, so that the workbench body and the detection unit become a whole.

[0015] Preferably, the side end surface of the inner support frame is in contact with the inner wall of the built-in cavity, and the bottom positions of the inner support frame and the hand-held frame are both connected to the inner cavity of the built-in groove. The airflow discharged from the inner cavity of the discharge hole moves downward along the inclined slide and the lower slide to the inner cavity of the built-in groove and the built-in cavity, so that the airflow can surround and impact the palms and wrists holding the hand-held frame with warm gas. This warm environment helps to soothe hand muscles, reduce stress and pain, and promote relaxation and blood circulation. The palms and wrists surrounded by warm gas provide a sense of comfort, making the patient feel relaxed and soothed during the treatment, thereby improving the treatment effect and the patient experience.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The operator adjusts the expansion mechanism as a whole using the opening groove of the sliding groove as a path. During the process of adjusting the position of the expansion mechanism, the lower end surface of the control tube can be adjusted to the position directly above the patient's eyeball, thereby improving the stability of the patient's eyes during the detection process and reducing the detection error caused by eye movement. At this time, the pressing block laterally supported by the outrigger rod expands the skin around the patient's eyes outward. This support can maintain the stability of the skin around the eyes and effectively unfold the upper and lower eyelids. When the sliding block is pushed downward by an external drive motor, the sliding block pushes the mounting plate and the assembly ring downward to move. When the bottoms of the four groups of pressing blocks are all in a supporting state, the upper and lower eyelids of the eye will be supported and unfolded. The control tube can be locked directly above the patient's pupil, thereby using the detection device set in the inner cavity of the detection tube to detect the patient's pupil, iris and other parts of the eyeball, and the patient's pupil position can be accurately and stably located, providing convenience for subsequent eye detection.

[0017] The patient's arm can pass through the inner cavity of the built-in groove, so that the patient's palm can hold the outer ring of the handheld frame in the inner cavity of the built-in groove, so that the patient can use force with his hand to distract his attention during the eye test, avoiding the situation of excessive tension in the eyes during the test and causing lack of energy.

[0018] The operator can guide the warm airflow into the inner cavity of the placement frame from the outside to the inside, and guide the warm airflow entering the inner cavity of the placement frame to be discharged downward through the discharge holes and the feed holes to ensure good airflow and avoid airflow stagnation. The warm airflow discharged from multiple channels hits the upper end surface of the table from top to bottom and slides downward to the inner cavity of the placement rack, thereby realizing a large area of ​​hot airflow distribution. Because the inner cavity walls on both sides of the placement rack can block the warm airflow, the warm airflow can temporarily surround the inner cavity of the placement rack, so that the head of the patient being tested can be surrounded by the warm airflow, which can relieve the patient's tension and improve the patient's comfort.

[0019] The airflow discharged from the inner cavity of the discharge hole moves downward along the inclined slide and the lower slide to the inner cavity of the built-in groove and the built-in cavity, so that the airflow can surround the palm and wrist holding the handheld frame with warm gas. This warm environment helps to relax the hand muscles, reduce pressure and pain, promote relaxation and blood circulation, and the palm and wrist surrounded by warm gas provide a sense of comfort, making the patient feel relaxed and soothed during the treatment, thereby improving the treatment effect and the patient experience.

The operator adjusts the expansion mechanism 24 as a whole along the opening groove of the sliding groove 233. During the position adjustment of the expansion mechanism 24, the lower end surface of the control cylinder 247 can be adjusted to the position just above the patient's eyeball, thereby improving the stability of the patient's eye during the detection process and reducing the detection error caused by eye movement. At this time, the pressing block 249 laterally supported by the extension rod 248 expands the patient's eyeball outward in all directions. The support can keep the skin around the eyes stable and effectively open the upper and lower eyelids. When the sliding block 241 is pushed downward by an external drive motor, the sliding block 241 pushes the mounting plate 242 and the assembly ring 243 downward to move. When the bottoms of the four groups of pressing blocks 249 are all in a supporting state, the upper and lower eyelids of the eyes will be supported and opened. The control tube 247 can be locked just above the patient's pupil, so that the detection device arranged in the inner cavity of the detection tube 246 can be used to detect the patient's pupil, iris and other parts of the eyeball, so that the patient's pupil position can be accurately and stably located, which provides convenience for subsequent eye detection.

The operator can guide the warm air flow from the outside to the inside into the inner cavity of the placement frame 213 and guide it into the placement frame 213. The warm airflow in the inner cavity of 13 is discharged downward through the discharge hole 215 and the discharge hole 216 to ensure good airflow and avoid airflow stagnation. The warm airflow discharged from multiple channels hits the upper end surface of the table 13 from top to bottom and slides downward to the inner cavity of the placement rack 15, thereby realizing a large-area hot airflow distribution. Because the inner cavity walls on both sides of the placement rack 15 can block the warm airflow, the warm airflow can temporarily surround the inner cavity of the placement rack 15, so that the head of the patient being tested can be surrounded by the warm airflow, which can relieve the patient's tension and improve the patient's comfort.

The entire device is placed on the operating table. At this time, the patient who needs to be examined lies flat on the operating table with his head placed in the inner cavity of the placement frame 15. The patient's face is facing upward at this time, and it is ensured that one side of the ear can fit into the inner cavity wall of the placement frame 15 to avoid the patient's eyes colliding with the device components due to shaking during the examination.

[0028] In Example 5, one side of the built-in cavity 14 is set to a double-opening structure, and the other side of the built-in cavity 14 is set to a single-opening structure.

The patient's face is facing upward at this time, and it is ensured that one side of the ear can fit into the inner cavity wall of the placement frame 15 to avoid the situation where the patient's eyes collide with the device components due to shaking during the test.

[0031] The operator adjusts the expansion mechanism 24 as a whole along the opening groove of the sliding groove 233. During the process of adjusting the position of the expansion mechanism 24, the lower end surface of the control tube 247 can be adjusted to the position just above the patient's eyeball, thereby improving the stability of the patient's eye during the test and reducing the test error caused by the movement of the eye. At this time, the pressing block 249 laterally supported by the outrigger rod 248 expands the skin around the patient's eye outward. This support can maintain the stability of the skin around the eye and effectively unfold the upper and lower eyelids. When the sliding block 241 is pushed downward by the external drive motor, the sliding block 241 pushes the mounting plate 242 and the assembly ring 243 downward to move. When the bottoms of the four groups of pressing blocks 249 are all in a supporting state, the upper and lower eyelids of the eye will be supported and unfolded.

The warm airflow discharged from multiple channels hits the upper end surface of the table 13 from top to bottom and slides downward to the inner cavity of the placement rack 15, thereby realizing a large area of ​​hot air flow distribution. Because the inner cavity walls on both sides of the placement rack 15 can block the warm airflow, the warm airflow can temporarily surround the inner cavity of the placement rack 15, so that the head of the patient being tested can be surrounded by the warm airflow, which can relieve the patient's tension and improve the patient's comfort.

[0034] The airflow discharged from the inner cavity of the discharge hole 216 moves downward along the inclined slide 217 and the lower slide 224 to the inner cavity of the built-in groove 12 and the built-in cavity 14, so that the airflow can surround the palm and wrist of the hand holding the handheld frame 223 with warm gas. This warm environment helps to relax the hand muscles, reduce stress and pain, promote relaxation and blood circulation, and the palms and wrists surrounded by warm gas provide a sense of comfort, making the patient feel relaxed and soothed during the treatment process, thereby improving the treatment effect and the patient's experience.
