[0035] First embodiment:

[0036] See also Figures 1 to 3 ,in Figure 1 is a schematic diagram of the overall structure of the first embodiment of the present invention, Figure 2 is a top view of the entire first embodiment of the present invention, Figure 3 The present invention Figure 2 AA line cross-sectional view. The present invention provides a retinal tweezers with retinal scissoring function, comprising a retinal tweezers body 101 and two scissor assemblies, wherein the scissor assemblies include a fixed block 102, a mounting block 103, a blade 104, a U-shaped block 105, two clamping pads 106, a limiting unit and a spring 108, the fixed block 102 having a groove 107, the limiting unit including a limiting rod 109 and a shifting block 110, the fixed block 102 having two first through holes 111, and the U-shaped block 105 having two second through holes 112.

[0037] According to this specific embodiment, hold the shift block 110 and pull the limiting rod 109 out of the first through hole 111 and the second through hole 112. At this time, the spring 108 rebounds, and the U-shaped block 105 pops out of the groove 107. At the same time, the inner wall of the U-shaped block 105 abuts against the mounting block 103 to avoid complete separation from the groove 107. Then, the limiting rod 109 is reinserted for limiting and fixing. At this time, the blade 104 is wrapped and clamping can begin. The patient's retina is clamped by relying on the clamping pad 106 to avoid accidental injury to the blade 104 during clamping.

[0038] Among them, the fixed block 102 is fixedly connected to the retinal tweezers body 101 and is located at one end of the retinal tweezers body 101, the fixed block 102 has a groove 107, the mounting block 103 is fixedly connected to the fixed block 102 and is located inside the groove 107, the blade 104 is fixedly connected to the mounting block 103 and is located at one end of the mounting block 103, the U-shaped block 105 and the groove 107 are adapted to each other and are sleeved on both sides of the mounting block 103, the two clamping pads 106 are fixedly connected to the U-shaped block 105 and are located at both ends of the U-shaped block 105, and the limiting unit is arranged on the fixed block 102 and the U-shaped block 105. The retinal tweezers body 101 carries the two scissor assemblies, and the U-shaped block 105 is released from the limit by the limiting unit, and is moved out of the groove 107 and located on both sides of the blade 104, thereby wrapping the blade 104, and then the limiting unit is reused for limiting, and then the clamping pad 106 can be used to clamp the patient's retina to avoid accidental injury to the blade 104 during clamping. In this way, the blade 104 can be freely switched between wrapped and exposed, exposed for shearing when in use, and wrapped for clamping when not in use, to avoid accidental injury to doctors and patients. It has a protective function and is more convenient to use.

[0039] Secondly, the two ends of the spring 108 are movably connected to the U-shaped block 105 and the inner top wall of the groove 107. The spring 108 can drive the U-shaped block 105 to pop out of the groove 107 without manual extraction.

[0040] At the same time, the fixing block 102 has two first through holes 111, and the U-shaped block 105 has two second through holes 112. The limiting rods 109 are adapted to the two first through holes 111 and the two second through holes 112. The shifting block 110 is fixedly connected to the limiting rods 109 and is located at one end of the limiting rods 109. The other end of the limiting rods 109 sequentially passes through the corresponding first through holes 111 and the corresponding second through holes 112. Holding the shifting block 110, the limiting rods 109 are pulled out of the first through holes 111 and the second through holes 112. At this time, the spring 108 rebounds, and the U-shaped block 105 pops out of the groove 107. At the same time, the inner wall of the U-shaped block 105 abuts against the mounting block 103 to prevent it from completely leaving the groove 107. The limiting rods 109 are then reinserted for fixed positioning. At this time, the blade 104 is wrapped and clamping can begin.

[0041] When using the retinal tweezers with retinal scissoring function of this embodiment, hold the shift block 110 and pull the limiting rod 109 out of the first through hole 111 and the second through hole 112. At this time, the spring 108 rebounds, and the U-shaped block 105 pops out of the groove 107. At the same time, the inner wall of the U-shaped block 105 abuts against the mounting block 103 to avoid completely disengaging from the groove 107. Then the limiting rod 109 is reinserted for limiting fixation. At this time, the blade 104 is wrapped and clamping can begin. The patient's retina is clamped by relying on the clamping pad 106 to avoid accidental injury to the blade 104 during clamping. Through the above-mentioned structural setting, the blade 104 can be freely switched between wrapped and exposed. It is exposed for shearing when in use and wrapped for clamping when not in use, so as to avoid accidental injury to doctors and patients. It has a protective function and is more convenient to use.

[0044] According to this specific embodiment, the electromagnet switch 203 is pressed to energize the multiple electromagnets 201, which then attract the multiple metal blocks 202, so that the U-shaped block 105 is brought back to the groove 107, and the battery pack 204 provides power to the electromagnet 201.

[0045] The automatic retracting components are respectively arranged on the corresponding fixed blocks 102. The automatic retracting components can automatically retract the U-shaped block 105 without manually pressing it back into the groove 107, thereby improving the user experience.

[0046] Secondly, the multiple electromagnets 201 are all fixedly connected to the fixing block 102 and are sequentially distributed on the inner top wall of the groove 107. The multiple metal blocks 202 are all fixedly connected to the U-shaped block 105 and are sequentially distributed on the side of the U-shaped block 105 away from the mounting block 103. The electromagnet switch 203 is fixedly connected to the retinal forceps body 101 and is located on one side of the retinal forceps body 101. Pressing the electromagnet switch 203 energizes the multiple electromagnets 201, which in turn attract the multiple metal blocks 202, causing the U-shaped block 105 to be brought back into the groove 107.

[0047] Meanwhile, the battery pack 204 is fixedly connected to the retinal forceps body 101 and is located on one side of the retinal forceps body 101. The battery pack 204 is located on one side of the electromagnet switch 203. The battery pack 204 provides power to the electromagnet 201.

[0048] When using the retinal tweezers with retinal scissoring function of this embodiment, press the electromagnet switch 203 to energize the multiple electromagnets 201, which then attract each other with the multiple metal blocks 202, so that the U-shaped block 105 is brought back to the groove 107. The battery pack 204 provides power to the electromagnet 201, thereby allowing the U-shaped block 105 to automatically shrink without manually pressing it back into the groove 107, thereby improving the user experience.

[0052] According to this specific embodiment, the rubber pad 301 improves the grip feel and increases the friction to avoid slipping. The bolt 302 can fix the rubber pad 301 and can also be disassembled for cleaning and replacement.

[0053] The two gripping assemblies are sequentially arranged on the retinal forceps, which improves the doctor's grip and makes it easier to perform scissoring and forceps operations.

[0054] Secondly, the rubber pad 301 is sleeved on the outer wall of the retinal forceps body 101 and is connected to the retinal forceps body 101 via the bolt 302. The rubber pad 301 improves the grip and friction to prevent slipping. The bolt 302 can fix the rubber pad 301 and can also be disassembled for cleaning and replacement.
