Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a multifunctional ophthalmic surgical device. Background Art

[0002] Currently, when performing eye surgery on a patient, the patient is usually required to lie on a bed and then have his head fixed to facilitate the operation. Existing head fixation devices often simply fix the patient's head with two splints. However, for different patients, the different head lifting angles cannot be met. The fixation device only fixes the left and right sides of the patient's head, but not the upper and lower sides. In addition, the fixation device cannot adjust the fixing distance on both sides, which increases the difficulty of the operation. For this reason, we propose a multifunctional ophthalmic surgical device. Utility Model Content

[0003] The purpose of the utility model is to provide a multifunctional ophthalmic surgical device. The bolts are first loosened according to needs, and then the headrest assembly is manually rotated, so that the mounting column and the rotating sphere rotate accordingly. The rotating sphere rotates inside the rotating hemispherical shell to adjust the angle of the headrest assembly. When the angle adjustment is completed, the bolts are re-tightened so that the bolts limit the rotating sphere, thereby completing the angle limitation of the headrest assembly, making the headrest angle adjustment more convenient and more functional.

[0004] The technical solutions adopted by this utility model are as follows:

[0005] A multifunctional ophthalmic surgical device comprises a rotating assembly connected to an ophthalmic surgical bed plate, wherein a headrest assembly is connected to the rotating assembly and the rotating assembly is used for horizontal adjustment, vertical adjustment and combined adjustment of the headrest assembly.

[0006] Preferably, the rotating assembly includes a connecting block connected to the ophthalmic surgical bed plate by a screw, the side wall of the connecting block is provided with a connecting column, the end of the connecting column is provided with a rotating hemispherical shell, the rotating hemispherical shell is movably provided with a rotating sphere, and the rotating sphere is provided with a mounting column.

[0007] Preferably, the rotating hemispherical shell is tilted, the mounting post is tilted, the upper end of the rotating hemispherical shell is open, and the diameter of the upper end opening of the rotating hemispherical shell is smaller than the diameter of the rotating sphere.

[0008] Preferably, a threaded tube is connected to the outside of the rotating hemispherical shell, a bolt is threadedly connected to the inside of the threaded tube, and the end of the bolt is adapted to fit the rotating sphere.

[0009] Preferably, the headrest assembly includes a headrest base plate installed at the end of the mounting column, two slide rails are provided at the lower end of the headrest base plate, and the two slide rails are centrally symmetrically distributed about the center point of the headrest base plate, a gear rod is movably provided in the slide rail, a headrest side plate is provided at the end of the gear rod, a connecting frame is provided at the center of the headrest base plate, a rotating shaft is movably provided in the middle of the connecting frame, a driving gear is provided on the rotating shaft, and the driving gear is meshed with the two gear rods.

[0010] Preferably, the headrest bottom plate and the headrest side plate surfaces are provided with soft panels.

[0011] The technical effects achieved by this utility model are:

[0012] In the present invention, the bolt is first loosened as needed, and then the headrest assembly is manually rotated, so that the mounting post and the rotating ball rotate accordingly, and the rotating ball rotates inside the rotating semi-spherical shell to adjust the angle of the headrest assembly. When the angle adjustment is completed, the bolt is re-tightened so that the bolt restricts the rotating ball to complete the angle restriction of the headrest assembly. It should be noted that the rotating ball and the rotating semi-spherical shell are connected by a damping connection. When no other external force is applied, the rotating ball does not rotate and the semi-spherical shell rotates. The rotation of the driving gear is achieved by rotating the rotating shaft. Since the driving gear and the two gear rods are meshed with each other, the two gear rods slide at the same speed, and are simultaneously extended outward or simultaneously retracted inward, so that the two headrest side panels are simultaneously retracted outward or simultaneously moved toward the middle to protect the patient's head. It should be noted that the connecting frame and the rotating shaft are connected by a damping connection. When no other external force is applied, the rotating shaft does not rotate, thereby making the two headrest side panels more stable, the headrest angle adjustment more convenient, and the functionality stronger.

[0025] The utility model is composed of Figure 3-6It can be seen that the headrest angle adjustment is more convenient and more functional.

[0026] The rotating assembly 2 includes a connecting block 201 connected to the ophthalmic operating table 1 by a screw, a connecting column 202 is provided on the side wall of the connecting block 201, a rotating hemispherical shell 203 is provided at the end of the connecting column 202, the rotating hemispherical shell 203 is movably provided with a rotating sphere 204, and a mounting column 205 is provided on the rotating sphere 204; the rotating hemispherical shell 203 is tilted, the mounting column 205 is tilted, the upper end of the rotating hemispherical shell 203 is open, and the diameter of the opening at the upper end of the rotating hemispherical shell 203 is smaller than the diameter of the rotating sphere 204; a threaded tube 206 is connected to the outside of the rotating hemispherical shell 203, and a bolt 207 is threadedly connected to the inside of the threaded tube 206, and the end of the bolt 207 is adapted to the rotating sphere 204.

[0027] In actual use, the bolt 207 is loosened as needed, and then the headrest assembly 3 is manually rotated, so that the mounting column 205 and the rotating ball 204 rotate accordingly, and the rotating ball 204 rotates inside the rotating hemispherical shell 203 to adjust the angle of the headrest assembly 3. When the angle adjustment is completed, the bolt 207 is re-tightened so that the bolt 207 limits the rotating ball 204, thereby completing the angle of the headrest assembly 3. It should be noted that the rotating ball 204 and the rotating hemispherical shell 203 are connected in a damping manner. When no other external force is applied, the rotating ball 204 does not cause the rotating hemispherical shell 203 to rotate.

[0028] The headrest assembly 3 includes a headrest base plate 301 mounted at the end of the mounting column 205. Two slide rails 302 are provided at the lower end of the headrest base plate 301.

[0029] In actual use, the driving gear 307 is rotated by rotating the rotating shaft 306. Since the driving gear 307 is engaged with the two gear rods 303, the two gear rods 303 slide at the same speed, and extend outward at the same time or retract inward at the same time, so that the two headrest side panels 304 retract outward at the same time, or move closer to the middle at the same time, thereby protecting the patient's head. It should be noted that the connecting frame 305 and the rotating shaft 306 are connected by a damping connection. When not affected by other external forces, the rotating shaft 306 does not rotate, thereby making the two headrest side panels 304 more stable.

[0030] The working principle of the present invention is as follows: first loosen the bolt 207 as needed, then manually rotate the headrest assembly 3, so that the mounting post 205 and the rotating ball 204 rotate accordingly, and the rotating ball 204 rotates inside the rotating hemispherical shell 203 to adjust the angle of the headrest assembly 3. When the angle adjustment is completed, re-tighten the bolt 207 so that the bolt 207 limits the rotating ball 204 to complete the angle of the headrest assembly 3. It should be noted that the rotating ball 204 and the rotating hemispherical shell 203 are connected by a damping force. When not subjected to other external forces, the rotating ball 204 does not The hemispherical shell 203 is rotated to rotate, and the driving gear 307 is rotated by rotating the rotating shaft 306. Since the driving gear 307 is engaged with the two gear rods 303, the two gear rods 303 slide at the same speed, and extend outward at the same time or retract inward at the same time, so that the two headrest side panels 304 retract outward at the same time, or move closer to the middle at the same time, thereby protecting the patient's head. It should be noted that the connecting frame 305 and the rotating shaft 306 are connected by a damping connection. When not affected by other external forces, the rotating shaft 306 does not rotate, thereby making the two headrest side panels 304 more stable.
