Description

Technical Field

[0001] The invention relates to the technical field of ophthalmic surgery, in particular to an eye retractor for ophthalmic surgery. Background Art

[0002] Ophthalmic surgery can improve the patient's vision, relieve the patient's eye discomfort, and improve the patient's visual quality, thereby improving the patient's quality of life. During ophthalmic surgery, an ophthalmic surgical eye retractor is required; For example, a retractor for ophthalmic surgery with publication number CN202136474U belongs to the field of medical device technology. Its structure includes a retractor claw and a retractor arm. The retractor arm is in a "U" shape, and a screw is welded on the retractor arm, and a fixing nut is provided on the screw. Compared with the existing technology, this new retractor for ophthalmic surgery has the characteristics of reasonable design, simple structure, ingenious conception, and easy use. It can gather more muscle tissue, fully expose the surgical field, improve surgical efficiency, and reduce surgical time. Another example is an extraocular muscle retractor with publication number CN217908155U, which includes a first arm, a connecting arm and a second arm. The left side of the connecting arm is connected to the first arm, the right side of the connecting arm is connected to the second arm, the bottom of the first arm is connected to the first extension arm, the bottom of the second arm is connected to the second extension arm, the cross-sections of the first arm, the connecting arm and the second arm are "V" shaped, the bottoms of the first extension arm and the second extension arm are connected to a connecting piece, and the bottom of the connecting piece is connected to a limiting piece. The utility model is provided with a first arm and a second arm, and there is a certain elasticity between the first arm, the connecting arm and the second arm. By pressing the first arm and the second arm, the first extension arm and the second extension arm are brought into contact with the extraocular muscles, thereby loosening the first arm and the second arm, and the connecting arm will move the first arm and the second arm, so that the first extension arm and the second extension arm stretch the extraocular muscles; During the operation, the jaws need to be adjusted quickly to accommodate different patients. However, the device in the above application is not convenient for quickly adjusting the angle during use, and the working efficiency of the device is low. At the same time, during the working process, the patient and the staff need to concentrate to facilitate the normal progress of the operation. However, the device in the above application does not have a warning structure during use, and the overall safety of the device is low.

[0003] In view of the above problems, it is urgently necessary to carry out innovative design based on the original ophthalmic surgical eye retractor. Summary of the invention

[0004] The object of the present invention is to provide an eye retractor for ophthalmic surgery to solve the problems raised in the above background technology that the angle cannot be adjusted quickly during use, the working efficiency of the device is low, and there is no warning structure during use, resulting in low overall safety of the device.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an ophthalmic surgical eye retractor, comprising a No. 1 handle, a No. 2 handle and a clamping claw, the left sides of the No. 1 handle and the No. 2 handle are both fixedly mounted with a connecting rod, and a connecting shaft is rotatably arranged inside the connecting rod, and a transition block is fixedly mounted on the left side of the connecting rod, and a long rod is fixedly mounted on the left side of the transition block; The clamping claw is inserted into the interior of the long rod, and a deep groove corresponding to the clamping claw is opened on the surface of the long rod; An ophthalmic surgical eye retractor, further comprising: A long strip, the long strip being fixedly mounted on the surface of the first handle; A first overlapping block, wherein the first overlapping block is fixedly mounted on the lower surface of the upper transition block, a traction rope is fixedly connected to the surface of the first overlapping block, and a second overlapping block is fixedly mounted on the upper surface of the lower transition block; A locking assembly is installed inside the second handle, and the locking assembly can lock the first handle so that the first handle no longer rotates clockwise; The warning component is installed on the surface of the second overlapping block. The warning component serves as a reminder and warning, allowing patients and medical staff to concentrate their attention. At the same time, a transition shaft is rotatably arranged on the surface of the second overlapping block.

[0006] Preferably, magnets are fixedly mounted on the end of the clamp and the inner wall of the long rod, and the magnetic poles of adjacent magnets at adjacent positions are opposite. Before work, the clamp needs to be installed inside the long rod. During specific operation, it is only necessary to insert the clamp into the deep groove. At this time, the clamp stays stably in the long rod under the action of the mutual magnetic force between adjacent magnets. After use, the clamp can be pulled out, which is convenient for the staff to clean, disinfect and store the clamp.

[0007] Preferably, the locking assembly includes a block slidably arranged inside the second handle, a slot corresponding to the block is opened on the right side of the long strip, and the long strip is an arc-shaped structure, and the center of the long strip is at the same point as the center of the connecting shaft.

[0008] Preferably, the card slots are distributed at equal angles on the surface of the strip, and the upper surface of the card block is an arc-shaped structure.

[0009] Preferably, a connecting spring that plays an elastic reset role is fixedly installed at the end of the card block, and the other side of the connecting spring is fixedly connected to the inner wall of the number two handle. When in use, hold the number one handle and the number two handle, and then rotate the number one handle. At this time, the long strip will slide inside the number two handle. When the long strip slides, it will push the card block through the inclined surface of the card block. At this time, the card block will move in the direction of squeezing the connecting spring. When the card block and the card slot are in the same direction along the number two handle, the card block enters the card slot under the action of the connecting spring, and the number one handle will no longer rotate. That is, the staff can use the clamp according to different patients, thereby improving work efficiency.

[0010] Preferably, a fixing block is fixedly installed on the surface of the card block, and the fixing block passes through the interior of the number two handle, and a shifting block is fixedly installed on the end of the fixing block. After use, when the number one handle needs to be returned to its original position, the shifting block is pushed, and the shifting block drives the fixed block and the card block to move away from the card slot. When the end of the card block moves out of the card slot, the number one handle and the number two handle are not in a locked state, and the number one handle can be rotated back to its original position for easy use later.

[0011] Preferably, the warning component includes a rotating shaft rotatably arranged on the surface of the second overlapping block, the surface of the traction rope is fitted with the surface of the transition shaft, and the end of the traction rope is sleeved and connected to the surface of the rotating shaft. During use, when the No. 1 handle is rotated, it will drive the first overlapping block to rotate synchronously. At this time, the first overlapping block will drive the rotating shaft to rotate on the surface of the second overlapping block through the traction rope.

[0012] Preferably, the warning component also includes a connecting circular frame fixedly mounted on the surface of the second overlapping block, and a clicker is fixedly mounted on the inner wall of the connecting circular frame, and the clickers are distributed at equal angles on the inner wall of the connecting circular frame. When the rotating shaft rotates, it will drive the knocking rod to rotate. When the knocking rod rotates, it will hit the clicker, and the clicker will make a sound, which serves as a warning and reminder, thereby improving safety.

[0013] Preferably, a knocking rod corresponding to the clicker is fixedly mounted on the surface of the rotating shaft, and the knocking rod is distributed at equal angles on the surface of the rotating shaft. A limiting rod is fixedly mounted on the upper surface of the second overlapping block. The knocking rod and clicker distributed at equal angles optimize the warning effect.

[0014] Preferably, the surface of the rotating shaft is concave, and a protrusion is fixedly installed on the surface of the rotating shaft, and a torsion spring that plays an elastic reset role is fixedly installed on the surface of the protrusion, and the other side of the torsion spring is fixedly connected to the inner wall of the second overlapping block. When the rotating shaft rotates, the protrusion is driven to rotate synchronously, and the protrusion will stretch the torsion spring. When the shift block drives the card block to move out of the card slot, handle No. 1 and handle No. 2 are not in an engaged state. At this time, the rotating shaft loses the tension of the traction rope, and then the rotating shaft rotates under the action of the protrusion and the torsion spring. When the rotating shaft rotates, the traction rope will be reeled in, and then the traction rope will pull handle No. 1 back to its original position, which is convenient for the staff's operation. At the same time, the transition shaft maximizes the tension of the traction rope.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the ophthalmic surgery eye retractor adopts a new structural design, and its specific contents are as follows: (1) Before the ophthalmic surgery eye retractor is used, the jaws need to be installed inside the long rod. During the specific operation, the jaws only need to be inserted into the deep groove. At this time, the jaws stay stably in the long rod due to the mutual magnetic force between adjacent magnets. After use, the jaws can be pulled out, which is convenient for the staff to clean, disinfect and store the jaws; (2) When using the ophthalmic surgical eye retractor, hold the No. 1 handle and the No. 2 handle, and then rotate the No. 1 handle. At this time, the long strip will slide inside the No. 2 handle. When the clamping block and the clamping slot are in the same direction along the No. 2 handle, the clamping block enters the clamping slot under the action of the connecting spring, and the No. 1 handle will not rotate anymore. That is, the staff can use the clamping claw according to different patients, thereby improving work efficiency. (3) When the No. 1 handle of the ophthalmic surgery eye retractor rotates, the No. 1 handle will drive the first overlap block to rotate synchronously. At this time, the first overlap block drives the rotating shaft to rotate through the traction rope. When the rotating shaft rotates, it drives the knocking rod to rotate. When the knocking rod rotates, it will hit the clicker, and the clicker will make a sound, which serves as a warning and reminder, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

The locking assembly can clamp the number one handle 1 so that the number one handle 1 no longer rotates clockwise. A warning assembly is installed on the surface of the second overlap block 18. The warning assembly serves as a reminder and warning, so that both the patient and the medical staff can concentrate. At the same time, a transition shaft 21 is rotatably arranged on the surface of the second overlap block 18. Magnets 9 are fixedly mounted on the end of the clamp 7 and the inner wall of the long rod 6, and the magnetic poles of adjacent magnets 9 at adjacent positions are opposite.

[0020] Before work, the clamp 7 needs to be installed inside the long rod 6. During the specific operation, the clamp 7 only needs to be inserted into the deep groove 8. At this time, the clamp 7 stays stably in the long rod 6 under the action of the mutual magnetic force between adjacent magnets 9. After use, the clamp 7 can be pulled out, which is convenient for the staff to clean, disinfect and store the clamp 7.

[0021] The locking assembly includes a block 12 slidably disposed inside the second handle 2, a slot 11 corresponding to the block 12 is provided on the right side of the strip 10, and the strip 10 is an arc-shaped structure, and the center of the strip 10 is at the same point as the center of the connecting shaft 4.

[0022] The card slots 11 are distributed at equal angles on the surface of the strip 10, the upper surface of the card block 12 is an arc-shaped structure, a connecting spring 13 which plays an elastic reset role is fixedly installed at the end of the card block 12, and the other side of the connecting spring 13 is fixedly connected to the inner wall of the second handle 2, a fixing block 14 is fixedly installed on the surface of the card block 12, and the fixing block 14 passes through the interior of the second handle 2, and a shift block 15 is fixedly installed at the end of the fixing block 14.

[0023] When in use, hold the No. 1 handle 1 and the No. 2 handle 2, and then rotate the No. 1 handle 1. At this time, the long strip 10 will slide inside the No. 2 handle 2. When the long strip 10 slides, it will push the block 12 through the inclined surface of the block 12. At this time, the block 12 will slide inside the No. 2 handle 2, and then the block 12 will squeeze the connecting spring 13. When the block 12 and the slot 11 are in the same direction along the No. 2 handle 2, the block 12 enters the slot 11 under the action of the connecting spring 13, and then the No. 1 handle 1 will no longer rotate clockwise, that is, the staff can use the clamping claw 7 according to different patients, thereby improving work efficiency. After use, when it is necessary to return the No. 1 handle 1 to its original position, push the shift block 15, and the shift block 15 drives the fixed block 14 and the block 12 to move away from the slot 11. When the end of the block 12 moves out of the slot 11, the No. 1 handle 1 and the No. 2 handle 2 are not in a locked state, and then the No. 1 handle 1 can be rotated back to its original position for subsequent use.

[0024] The warning component includes a rotating shaft 20 rotatably arranged on the surface of the second overlapping block 18, the surface of the traction rope 17 is fitted with the surface of the transition shaft 21, and the end of the traction rope 17 is sleeved and connected to the surface of the rotating shaft 20.

A limiting rod 19 is fixedly installed on the upper surface of the second overlapping block 18. The surface of the rotating shaft 20 is concave, and a protrusion 25 is fixedly installed on the surface of the rotating shaft 20. A torsion spring 26 that plays an elastic reset role is fixedly installed on the surface of the protrusion 25, and the other side of the torsion spring 26 is fixedly connected to the inner wall of the second overlapping block 18.

[0026] When the No. 1 handle 1 rotates, the No. 1 handle 1 will drive the first overlap block 16 to rotate synchronously. At this time, the first overlap block 16 drives the rotating shaft 20 to rotate on the surface of the second overlap block 18 through the traction rope 17. When the rotating shaft 20 rotates (the torsion spring 26 will be stretched through the protrusion 25), it will drive the knocking rod 23 to rotate synchronously.
