[0003] The vitrectomy machine used for vitrectomy surgery is referred to as the vitrectomy machine. The vitreous is a semisolid gelatinous substance inside the eye that fills the vitreous cavity. Under normal circumstances, the vitreous has good light transmittance and can make the retina and choroid stick together. If the vitreous is diseased, the mildest case will feel like there are mosquitoes flying in front of the eyes when looking at things, and the eyes will be blind in severe cases. There may even be lesions in the tissues around the vitreous, such as retinal detachment, which will damage the entire eyeball. In medical clinical surgery, the vitrectomy machine can be used to remove turbid vitreous or vitreoretinal traction, restore transparent refractive media and promote retinal reposition, treat vitreoretinal diseases, and restore the patient's visual function.

[0004] During vitrectomy, light is transmitted to the eye through optical fiber to form a beam of light, creating the Tyndall effect, making it easier to identify the relatively transparent vitreous body. In related technologies, the optical fiber is connected to the optical fiber connector on the main unit of the vitrectomy machine through an optical fiber connector. When the optical fiber connector is docked with the optical fiber connector, it is difficult to determine whether the optical fiber connector is properly plugged in relative to the optical fiber connector.

[0046] Reference Figures 1 to 4 As shown, the embodiment of the present disclosure provides an optical fiber connection structure, which includes a connection seat 100 , a connector 200 and an elastic member 300 .

[0047] In this embodiment, the connection seat 100 is connected to the signal circuit, and a sleeve 110 is arranged on it. A first optical fiber 120 is passed through the connection seat 100, and the first optical fiber 120 is exposed in the sleeve 110. In this embodiment, the connector 200 includes an optical fiber tube 210 and a locking assembly 220 sleeved on the optical fiber tube 210. A second optical fiber 230 is passed through the optical fiber tube 210. The optical fiber tube 210 can be inserted into the sleeve 110, and the locking assembly 220 can be detachably connected to the sleeve 110. When the locking assembly 220 is connected to the sleeve 110, the optical fiber tube 210 is in contact with the connection seat 100; the elastic member 300 is arranged between the connector 200 and the connection seat 100, the elastic member 300 can be in contact with the locking assembly 220, and the elastic member 300 makes the locking assembly 220 have a tendency to move away from the connection seat 100, and the elastic member 300 is used to connect the signal circuit. When the connector 200 and the connector base 100 are plugged into place, a conducting loop is formed among the signal circuit, the elastic member 300 , the locking assembly 220 and the optical fiber tube 210 on the connector 200 , and the connector base 100 .

[0048] In this embodiment, when the connection base 100 and the connector 200 are plugged into place, the first optical fiber 120 inserted on the connection base 100 and inserted in the sleeve 110 and the second optical fiber 230 inserted in the optical fiber tube 210 are coaxially opposite to each other.

[0049] In this embodiment, when the elastic member 300 is connected to the signal circuit, the connector 200 and the connector seat 100 in the optical fiber connection structure are connected, and by detecting whether the elastic member 300, the connector 200, and the connector seat 100 are in contact and conductive, it can be identified whether the connector 200 is plugged in place relative to the connector seat 100. It can be understood that by checking whether the signal circuit, the elastic member 300, the locking assembly 220 on the connector 200, the optical fiber tube 210, and the connector seat 100 form a loop, it is determined whether the connector 200 is plugged in place relative to the connector seat 100. Exemplarily, the signal circuit connected to the elastic member 300 can be a host of a phacovitrectomy machine.

[0050] The principle is as follows: when the elastic member 300 is connected to the signal circuit, the connector 200 and the connector seat 100 in the optical fiber connection structure are connected, so that the optical fiber tube 210 on the connector 200 is inserted into the sleeve 110 on the connector seat 100, and the locking assembly 220 and the sleeve 110 are connected, so that the locking assembly 220 and the elastic member 300 are in contact and conduction and squeeze the elastic member 300. As the locking assembly 220 and the sleeve 110 on the connector 200 are continuously connected, the connector 200 can be in contact and conduction with the connector seat 100 through the optical fiber tube 210, thereby the elastic member 300, the locking assembly 220 and the optical fiber tube 210 on the connector 200, and the connector seat 100 are in contact and conduction in turn. If the elastic member 300, the locking assembly 220 on the connector 200 and the optical fiber tube 210, and the connector seat 100 are in contact and connected in sequence, it indicates that the loop formed between the signal circuit, the elastic member 300, the locking assembly 220 on the connector 200 and the optical fiber tube 210, and the connector seat 100 is connected, and the connector 200 has been plugged into place relative to the connector seat 100; otherwise, it indicates that the loop formed between the signal circuit, the elastic member 300, the locking assembly 220 on the connector 200 and the optical fiber tube 210, and the connector seat 100 is disconnected, and the connector 200 has not been plugged into place relative to the connector seat 100. Therefore, the optical fiber connection structure provided in the embodiment of the present disclosure has a plug-in detection function, so that in the process of connecting the connector 200 and the connector seat 100 of the optical fiber connection structure, it can automatically detect whether the two have been plugged into place, so that the user can perceive and identify, thereby effectively ensuring the coupling efficiency of the connector 200 and the connector seat 100.

[0051] In addition, in this embodiment, the elastic member 300 makes the locking assembly 220 have a tendency to move away from the connection base 100, so that the locking assembly 220 and the elastic member 300 can achieve stable contact and resistance, effectively ensuring the stability of the conduction between the locking assembly 220 and the elastic member 300, and further effectively ensuring that the signal circuit detects and recognizes that the connector 200 is plugged into the connection base 100 stably and reliably. In addition, the elastic member 300 makes the locking assembly 220 have a tendency to move away from the connection base 100, and can also effectively prevent the connection between the locking assembly 220 and the sleeve 110 from loosening.

[0052] In this embodiment, refer to Figure 1 , Figure 2 , Figures 4 to 6 As shown, the locking assembly 220 can be connected to the sleeve 110 by threaded connection. Exemplarily, when the connector 200 is connected to the connection seat 100, the optical fiber tube 210 is inserted into the sleeve 110, and the locking assembly 220 is screwed relative to the sleeve 110. The locking assembly 220 drives the optical fiber tube 210 close to the connection seat 100. When the optical fiber tube 210 abuts against the connection seat 100, the locking assembly 220 just contacts and squeezes the elastic member 300, so that the elastic member 300, the locking assembly 220, the optical fiber tube 210 and the connection seat 100 are contacted and connected in sequence. Therefore, by detecting whether the elastic member 300, the locking assembly 220, the optical fiber tube 210 and the connection seat 100 are connected, it can be identified whether the connector 200 is plugged in place relative to the connection seat 100.

[0053] In this embodiment, the locking assembly 220 may include a threaded sleeve 221, an insulating ring 222, a hand-tightening ring 223 and a fastener 224. The threaded sleeve 221 is rotatably sleeved on the optical fiber tube 210, and the threaded sleeve 221 can be sleeved on the sleeve 110 and threadedly connected with the sleeve 110. The insulating ring 222 is sleeved on the threaded sleeve 221. The hand-tightening ring 223 is sleeved on the insulating ring 222. The fastener 224 sequentially penetrates the periphery of the hand-tightening ring 223 and the periphery of the insulating ring 222 and abuts against the periphery of the threaded sleeve 221, and the fastener 224 is threadedly connected with the hand-tightening ring 223. In this embodiment, through the provision of the insulating ring 222, the hand-tightening ring 223, the fastener 224, the threaded sleeve 221 and the optical fiber tube 210 can be contacted and connected in sequence, effectively preventing the hand-tightening ring 223 from passing over the fastener 224 and directly connecting with the threaded sleeve 221. It can be understood that when the elastic member 300 is connected to the signal circuit, when the connector 200 is plugged into place relative to the connecting seat 100, a conductive loop is formed between the signal circuit, the elastic member 300, the hand-tightening ring 223, the fastener 224, the threaded sleeve 221, the optical fiber tube 210 and the connecting seat 100, which can effectively ensure the stability of the current signal in the signal circuit, and thereby ensure that the identification of whether the connector 200 is plugged into place relative to the connecting seat 100 is stable and reliable.

[0054] In this embodiment, a first annular boss 211 is provided on the periphery of the optical fiber tube 210, and a second annular boss 2211 is formed by radially extending the inner side wall of one end of the threaded sleeve 221 away from the connecting seat 100, and the second annular boss 2211 is located on the side of the first annular boss 211 away from the connecting seat 100, and the end of the second annular boss 2211 facing the first annular boss 211 can abut against the end of the first annular boss 211 facing the second annular boss 2211. In this embodiment, when the connector 200 is plugged into place relative to the connecting seat 100, the optical fiber tube 210 abuts against the connecting seat 100, and the end of the second annular boss 2211 facing the first annular boss 211 abuts against the end of the first annular boss 211 facing the second annular boss 2211, so that the connecting seat 100 and the second annular boss 2211 can form a clamping effect on the optical fiber tube 210, effectively ensuring that the conduction between the threaded sleeve 221, the optical fiber tube 210 and the connecting seat 100 is stable and reliable.

[0055] In this embodiment, the circumference of the threaded sleeve 221 may be provided with a third annular boss 2212, and the circumference of the third annular boss 2212 is arranged to fit with the inner annular surface of the insulating ring 222. In this embodiment, the threaded sleeve 221 fits with the inner annular surface of the insulating ring 222 through the circumference of the third annular boss 2212, which can ensure that the threaded sleeve 221 and the insulating ring 222 are relatively fixed in the radial direction, stable and reliable, and can effectively reduce the contact area with the insulating ring 222, that is, reduce the contact friction with the insulating ring 222, and facilitate assembly with the insulating ring 222.

[0056] In this embodiment, the fastener 224 can abut against the third annular boss 2212. In this embodiment, the circumference of the third annular boss 2212 fits the inner annular surface of the insulating ring 222, and the fastener 224 abuts against the third annular boss 2212. Compared with the abutment of the fastener 224 against other areas of the threaded sleeve 221, the threaded sleeve 221 can be effectively prevented from being skewed relative to the hand-tightening ring 223, and the threaded sleeve 221 can be stably pressed and fixed in the hand-tightening ring 223.

[0057] In this embodiment, the inner ring surface of the hand-tightening ring 223 can be stepped, including a first inner ring surface 2231, a second inner ring surface 2232 and a step surface 2233 arranged between the first inner ring surface 2231 and the second inner ring surface 2232. The diameter of the first inner ring surface 2231 is greater than the diameter of the second inner ring surface 2232. The first inner ring surface 2231 is located on the side of the second inner ring surface 2232 close to the connecting seat 100. The insulating ring 222 is arranged in the first inner ring surface 2231 and is closely fitted with the first inner ring surface 2231, which can ensure that the hand-tightening ring 223 and the insulating ring 222 are relatively fixed in the radial direction, stably and reliably. The end of the insulating ring 222 away from the connecting seat 100 is closely fitted with the step surface 2233, which can realize the axial positioning of the insulating ring 222 relative to the hand-tightening ring 223, which is stable and reliable.

[0058] In other embodiments, the locking assembly 220 may also be connected to the sleeve 110 by snap-fitting or other connection methods, which is not limited in the present disclosure.

[0059] In this embodiment, the signal circuit can be connected to a current detection device (not shown), and the current detection device can form a loop between the signal circuit, the elastic member 300, the locking assembly 220, the optical fiber tube 210, and the connecting socket 100. The current detection device can identify whether the connector 200 is properly plugged into the connecting socket 100 by detecting whether there is current in the loop.

[0060] In a feasible embodiment, the optical fiber connection structure may include a plurality of connectors 200, the connection seat 100 is connected to one of the connectors 200, and the resistance of the fastener 224 of each connector 200 in the plurality of connectors 200 is different. When the fasteners 224 with different resistance values ​​are connected in series to the signal circuit, the current values ​​flowing through the signal circuit are different. By detecting the current value of the signal circuit, the model type of the connected connector 200 can be identified.

[0061] Exemplarily, the material of the fastener 224 includes, but is not limited to, metal aluminum, aluminum alloy, or stainless steel.

[0062] In other embodiments, the signal circuit may also be detected by a voltage detection device or other detection devices, which is not limited in the present disclosure.

[0063] In a feasible implementation, the connector 200 further includes a protective sleeve 240, in which the second optical fiber 230 is inserted, and the protective sleeve 240 is sleeved on an end of the optical fiber tube 210 away from the connector 100. In this embodiment, the protective sleeve 240 can protect the second optical fiber 230 from damage by external forces and the environment, and maintain the transmission performance of the second optical fiber 230.

[0064] For example, the protective cover 240 may be made of a high-strength material that can withstand tension, pressure, and bending to prevent the optical fiber from breaking or being damaged during operation.

[0065] In a possible implementation, Figure 4 As shown, an annular groove 101 is provided on one side of the connecting seat 100, and the sleeve 110 is inserted into the annular groove 101, which facilitates the positioning and assembly of the sleeve 110 relative to the connecting seat 100, and effectively ensures the coaxial accuracy between the first optical fiber 120 and the second optical fiber 230 when the connector 200 is plugged into place relative to the connecting seat 100.

[0066] In a possible implementation, Figure 4 As shown, the inner side wall of one end of the sleeve 110 facing the connecting seat 100 extends along its own axial direction to form an annular platform 111, and the annular platform 111 is inserted into the annular groove 101 to facilitate the axial positioning and assembly of the sleeve 110 relative to the connecting seat 100.

[0067] In a possible implementation, Figure 7 As shown, the elastic member 300 includes an open ring portion 310, and the two ends of the open ring portion 310 extend to form support arms 320, the open ring portion 310 is sleeved on the sleeve 110, and the support arms 320 are used to connect the signal circuit. In this embodiment, when the connector 200 is plugged into place relative to the connector seat 100, the open ring portion 310 and the locking assembly 220 are abutted against each other, so that the elastic member 300, the locking assembly 220, the optical fiber tube 210 and the connector seat 100 are contacted and connected in sequence, which is stable and reliable.

[0068] Exemplarily, the end of the support arm portion 320 can remain relatively fixed with the connecting seat 100 , and when the open ring portion 310 abuts against the locking assembly 220 , the elastic member 300 causes the locking assembly 220 to have a tendency to move away from the connecting seat 100 .

[0069] Specifically, the open ring portion 310 abuts against the hand-tightening ring 223 .
