[0043] 2. The present invention adopts a linked forehead fixing part and chin support. After the patient's head leans on the head contouring pad, the operator pushes the forehead fixing part and chin support part from both sides toward the middle with both hands, and uses the forehead fixing part and chin support part to fix the patient's head. During the adjustment process, when one of the first tooth plate and the second tooth plate is in a sliding state, the interlocking assembly will be in an unlocked state for the other. The user can not only adjust the forehead fixing part and chin support part to clamp the patient's head, but also adjust the position of the forehead fixing part and chin support part as a whole, which is very convenient to adjust.

[0044] 3. The present invention is designed with an adjustable base that can slide along the length of the patient's head and can slide up and down to adjust the height of the surgical instrument holder, so that the surgical instrument holder has a wider range of use; the surgical instrument holder is designed as an operating table that can be rotated upward. During its use, the operating table is pressed by the surgical operator in a horizontal state. When the operation is finished or stopped, the user does not need to adjust the adjustable base, and can directly lift the operating table to quickly move the surgical instrument away from the patient's eyes. The operation is very convenient; a transparent plate is installed on one side of the operating table. During the operation, the transparent plate is covered above the patient's eyes, and the surgeon is not easy to get debris, sweat, The invention discloses a special scalpel which is designed to increase the safety of the operation by preventing the scraps of clothing from falling into the patient's eyes. The special scalpel is designed (a ball part is added to the handle of a conventional scalpel), and an elastic ball ring protruding upward and a rigid ball ring protruding downward are designed on the operating table. The ball part is fixedly connected to the top of the elastic ball ring. When the surgeon operates the special scalpel, it needs to exert downward force to deform the elastic ball ring. When the force is reduced, the special scalpel can be placed in a higher position under the action of the elastic ball ring's own rebound force. Compared with the surgeon operating the scalpel in mid-air, the special scalpel is more stable and easier for the surgeon to operate. The rigid ball ring at the bottom plays a limiting role to prevent the surgeon from exerting too much force and causing greater harm to the patient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0062] Example 1:

[0063] like Figures 1-15 As shown, an embodiment of the present invention provides an ophthalmic surgical fixation device, comprising: a head support 1, an eyeball support 2, an adjustment component 3, an adjustment base 5, and a surgical instrument support 4; the head support 1 is used to fix the patient's head to prevent the patient's head from moving during the operation and affecting the normal progress of the operation; the eyeball support 2 is located above the head support 1 and is used to fix the eyeball and keep the eyeball stable during the operation; the main part of the adjustment component 3 is fixedly installed with the head support 1, and the adjustable end of the adjustment component 3 is fixedly installed with the eyeball support 2 to adjust the position and angle of the eyeball support 2; after the head support 1 is fixed with the patient's head, the eyeball support 2 follows to reach the patient's eye, and then the adjustment component 3 is used to adjust the specific position of the eyeball support 2 to It is supported on the upper and lower eyelids of the patient, which can well stabilize the patient's requirements and avoid the movement of the eyeball during the operation. The main part of the adjustment base 5 is fixed, which can be fixed to the ground, or installed together with the head support 1 on the same bed or chair, keeping the adjustment base 5 and the head support 1 relatively fixed. The adjustable end of the adjustment base 5 is fixedly installed with the surgical instrument support 4, so that the surgical instrument support 4 is located on one side of the eyeball support 2, which is used to assist in stabilizing the surgical instrument, maintain the stability of the surgical instrument during the operation, assist the operator's operation, ensure the accuracy and safety during the operation, and provide a better operating environment for ophthalmic surgery. The application of this device will help improve the success rate of ophthalmic surgery and the treatment effect of patients.

[0064] In one embodiment, the head support 1 includes: a hard pad 101 , a forehead fixing member 102 , a chin support member 103 and an interlocking assembly 105 .

[0065] The hard pad 101 is shaped like the back and head of a human body and can be fixed on the bed board. A head-shaped pad 104 is fixedly installed on the top of the hard pad 101. The head-shaped pad 104 matches the shape of the human head and has a concave portion for the head and a supporting portion for the neck. When the patient leans on it, he can have a more comfortable feeling. The surface of the head-shaped pad 104 has a flexible pad. The thickness of the flexible pad should not be too thick, and should be 1.5-3MM to avoid affecting the fixation of the forehead fixing part 102 and the chin supporting part 103. The forehead fixing part 102 and the chin supporting part 103 are both arranged above the head-shaped pad 104, corresponding to the forehead and chin of the patient on the head-shaped pad 104, fixing the patient's head from the upper and lower positions. The interlocking component 105 is fixedly installed with the hard pad 101, and the one-way sliding card on the interlocking component 105 is provided with a first tooth plate 1 06, second tooth plate 107, the first tooth plate 106, the second tooth plate 107 and the interlocking assembly 105 are allowed to slide in opposite directions, that is, the first tooth plate 106, the second tooth plate 107 can slide freely toward the middle, the forehead fixing part 102 is fixedly connected to the first tooth plate 106 through the connecting frame 108, and the chin support 103 is fixedly connected to the second tooth plate 107 through the connecting part, so that the forehead fixing part 102 and the chin support 103 can be controlled to slide freely toward the middle, thereby fixing the patient well. When one of the first tooth plate 106 and the second tooth plate 107 is in a sliding state, the other is in an unlocked state, that is, when the first tooth plate 106 and the second tooth plate 107 can still slide toward the middle, the user can synchronously move the forehead fixing part 102 and the chin support 103 during the sliding of the first tooth plate 106 and the second tooth plate 107 toward the middle.

[0066] One way of using it is as follows: if the patient's head is not well positioned against the head contour pad 104, and it is necessary to move the patient's head upwards a little when clamping the head, the user simultaneously squeezes the forehead fixing member 102 and the chin support member 103 toward the middle with both hands, so that the forehead fixing member 102 and the chin support member 10 fix the patient's head. The user then appropriately adjusts the position of the forehead fixing member 102 so that the chin support member 10 pushes the patient's chin, causing the patient to move upwards a little, thereby ensuring that the patient's head fits well against the head contour pad 104.

[0067] In one embodiment, the interlocking assembly 105 includes a box body 1051 , an inverted “U”-shaped frame 1054 , an elastic member 1057 , and an anti-falling pin 1058 .

[0068] The top of the box body 1051 is open, and the side of the box body 1051 is provided with a first through hole 1052 and a second through hole 1053 distributed up and down. The second through hole 1053 is located above the first through hole 1052. The box body 1051 is fixedly installed with the hard pad 101, and the bottom of the inverted "U"-shaped frame 1054 is located on the inner side of the box body 1051, and the second tooth part 1056 is fixedly installed on the inner side of the inverted "U"-shaped frame 1054 at a position corresponding to the first through hole 1052, and the first tooth part 1055 is fixedly installed on the inner side of the inverted "U"-shaped frame 1054 at a position corresponding to the second through hole 1053. The inclined surfaces of the first tooth part 1055 and the second tooth part 1056 are opposite in direction, and the elastic part 1057 is fixedly installed on the inner bottom of the box body 1051 for elastically supporting the bottom end of the inverted "U"-shaped frame 1054.

[0069] For example, when the second tooth plate 107 moves toward the middle (referring to the middle position of the forehead fixing part 102 and the chin support part 103 when the forehead fixing part 102 and the chin support part 103 move close to each other), the inclined surface of the second tooth plate 107 squeezes the inclined surface of the first latching part 1055, causing the first latching part 1055 to move downward, thereby driving the inverted "U"-shaped frame 1054 to move downward, and the elastic part 1057 is compressed and deformed. At this time, the second latching part 1056 also moves downward synchronously; thereby, during the movement of the second tooth plate 107 toward the middle, the first tooth plate 106 can slide freely without being restricted by the second latching part 1056; on the contrary, if the first tooth plate 106 moves toward the middle, the second tooth plate 107 can also slide freely in two directions.

[0070] In order to prevent the inverted "U"-shaped frame 1054, the first latch 1055, and the second latch 1056 from moving upward and away from the box body 1051 when not in use, the top of the inverted "U"-shaped frame 1054 is extended out of the box body 1051, and the anti-falling nail 1058 is fixedly installed at the top opening of the box body 1051. The anti-falling nail 1058 is located on the inner side of the inverted "U"-shaped frame 1054. If the inverted "U"-shaped frame 1054 moves upward, the first latch 1055 will be restricted to prevent the inverted "U"-shaped frame 1054 from sliding upward and out of the box body 1051.

[0071] In one embodiment, the adjustment assembly 3 includes: a first adjustment ring 301 , an adjustment rod 302 , and a rotatable adjustment mounting assembly 303 .

[0072] A circular hole is provided on the side of the connecting frame body 108, and the first adjusting ring 301 is rotatably connected to the inner wall of the circular hole on the side of the connecting frame body 108. The inner side of the first adjusting ring 301 has an internal thread, and the end of the first adjusting ring 301 has a rough portion for manual rotation. One end of the adjusting rod 302 is threadedly connected to the first adjusting ring 301, and the other end of the adjusting rod 302 is fixedly installed with a rotatable adjustment mounting assembly 303, so that the user can control the adjusting rod 302 with one hand and rotate the first adjusting ring 301 with the other hand. At this time, the threaded pair between the first adjusting ring 301 and the adjusting rod 302 causes the adjusting rod 302 to move axially, thereby adjusting the extension length of the adjusting rod 302.

[0073] Specifically, the rotatable and adjustable mounting assembly 303 includes a first mounting assembly 3031 and a second mounting assembly 3032 . The first mounting assembly 3031 is rotatably connected to the second mounting assembly 3032 , and the first mounting assembly 3031 is fixedly mounted to the adjusting rod 302 .

[0074] The first mounting component 3031 and the second mounting component 3032 act as an intermediate connection and enable the eyeball holder 2 and the adjustment rod 302 to rotate freely. An axis is provided between the first mounting component 3031 and the second mounting component 3032, and the first mounting component 3031 and the second mounting component 3032 are in close contact. After the first mounting component 3031 and the second mounting component 3032 are rotated and adjusted relative to each other, they can automatically maintain their positions to facilitate adjustment. Different patients need to use eyeball holders 2 of different sizes, so the rotatable and adjustable mounting component 303 needs to ensure the convenience of installation. It is preferably adopted that a through hole is opened on the side of the first mounting component 3031 and the second mounting component 3032. After the joystick 201 of the eyeball holder 2 passes through the through hole, it is fixed with a screw. The same is true for the adjustment rod 302. After passing through the through hole on the first mounting component 3031, it is fixed with a screw.

[0075] The eyeball bracket 2 includes: a joystick 201, one end of the joystick 201 is fixedly mounted on the second mounting assembly 3032, the other end of the joystick 201 is fixedly mounted with a U-shaped clamp 202, and a ring member 203 is rotatably mounted on the inner side of the U-shaped clamp 202.

[0076] The ring 203 corresponds to the position of the human eye contour (the eye contour formed by the upper eyelid and the lower eyelid). It squeezes the eyelid position to open the eyes and can stabilize the position of the eyeball.

[0077] In one embodiment, the adjustment base 5 includes: a fixed frame 501 and an "L"-shaped sliding member 503. The fixed frame 501 is relatively fixed to the head support 1. It can be fixed to the ground or connected to a bed board together with the head support 1. It is necessary to keep the positions of the two fixed. When actually in use, it is necessary to ensure that the adjustment base 5 does not move. A long slot is provided on the top of the fixed frame 501. An "L"-shaped bracket 502 is fixedly installed on the inner side of the fixed frame 501. The foot of the "L"-shaped sliding member 503 is located on the inner side of the fixed frame 501 and is supported above the "L"-shaped bracket 502. The head of the "J"-shaped sliding member 503 extends upward from the long slot hole to the fixed frame 501. Relying on the elastic force of the two feet of the "J"-shaped sliding member 503 toward both sides, the feet of the "J"-shaped sliding member 503 are in close contact with the inner wall of the fixed frame 501. The "J"-shaped sliding member 503 is a metal plate with a certain elastic deformation ability. When in use, the user squeezes the feet of the "J"-shaped sliding member 503 inward, and then slides it along the length direction of the long slot hole. After sliding to the appropriate position, release the feet of the "J"-shaped sliding member 503, and it can automatically return to its original position under the action of elasticity.

[0078] A second adjusting ring 504 is rotatably mounted on the top of the "J"-shaped sliding member 503, and a lifting rod 505 is threadedly mounted on the inner side of the second adjusting ring 504. By manually rotating the second adjusting ring 504 and controlling the lifting rod 505 not to rotate, the lifting rod 505 is moved up and down by relying on the threaded pair between the second adjusting ring 504 and the lifting rod 505.

[0079] In one embodiment, the surgical instrument holder 4 includes a storage box 401 , a sliding mounting seat 408 , an operating table 402 , and a dedicated scalpel 404 .

[0080] The top of the storage box 401 is open, and the bottom of the storage box 401 is fixedly installed with the top of the lifting rod 505, which is adjusted and moved by the adjustment base 5. A bracket 405 is fixedly installed on the side of the storage box 401, and a rigid pad 406 is provided on the top of the bracket 405. The sliding mounting seat 408 is located inside the storage box 401 and slides, and a spring assembly 407 is fixedly installed on the bottom end of the sliding mounting seat 408. The bottom end of the spring assembly 407 is fixedly installed with the inner bottom of the storage box 401, and one end of the operating table 402 is rotatably connected to the top of the sliding mounting seat 408, as shown in FIG. Figure 11-12 As shown in the figure, the operating table 402 is in a horizontal state, the sliding mounting seat 408 at its end is rotatably connected, and the spring assembly 407 is in a stretched state, so that the operating table 402 has a tendency to rotate upward. The operator presses one hand on the top of the operating table 402 so that the bottom of the operating table 402 is pressed on the rigid pad 406. After completing the operation, the operator only needs to release the pressure on the operating table 402, and the operating table 402 will automatically swing upward.

[0081] A transparent plate 403 is fixedly installed on one side of the operating table 402 away from the sliding mounting seat 408. During the operation, the operating table 402 remains horizontal and the transparent plate 403 is located directly above the patient's eyes. The transparent plate covers the patient's eyes, which makes it difficult for the surgeon to drop debris, sweat, and clothing debris into the patient's eyes during the operation, thereby improving the safety of the operation. A stepped hole 410 is provided on the top of the transparent plate 403. The stepped hole 410 is a structure with a large upper part and a small lower part, that is, a large-diameter circular hole on the upper part and a small-diameter circular hole on the lower part. An elastic ball ring 411 is fixedly installed in the large hole of the stepped hole 410, and the elastic ball ring 411 protrudes upward. A rigid ball ring 412 is fixedly installed in the small hole of the stepped hole 410, and the rigid ball ring 412 protrudes downward. A ball portion 413 is provided in the middle section of the handle of the special scalpel 404. The ball portion 413 is located on the inner side of the rigid ball ring 412 and the elastic ball ring 411, and the ball portion 413 is fixedly connected to the top of the elastic ball ring 411.

[0082] When the surgeon operates the special scalpel 404, he needs to exert downward force to deform the elastic ball ring 411. When the force is reduced, the special scalpel 404 can be placed in a higher position under the action of the elastic ball ring 411's own rebound force. Compared with the surgeon operating the scalpel in mid-air, it is more stable and easier for the surgeon to operate. The rigid ball ring 412 at the bottom plays a limiting role to prevent the surgeon from exerting too much force and causing greater harm to the patient.

[0083] In one embodiment, the sliding mounting seat 408 is an inverted "T"-shaped structure, and a limiting pin 409 is fixedly installed on the side of the storage box 401 and above the horizontal plate of the sliding mounting seat 408. The limiting pin 409 limits the highest position of the sliding mounting seat 408 to slide upward, preventing the sliding mounting seat 408 from sliding upward and out of the storage box 401.

[0084] In one embodiment, an annular sleeve 415 is provided at the top of the elastic ball ring 411, and a cylindrical mounting portion 414 is provided on the side of the ball portion 413. The annular sleeve 415 is sleeved on the outside of the cylindrical mounting portion 414, and multiple screws are horizontally installed from the outside of the annular sleeve 415 to fix the annular sleeve 415 to the cylindrical mounting portion 414. This structural design makes the connection between the annular sleeve 415 and the cylindrical mounting portion 414 more convenient, and the connection of multiple screws is more stable.

[0085] In one embodiment, the upper surface of the operating table 402 is a rough surface to prevent the operating table 402 from slipping when being pressed down.

[0086] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
