Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic surgery auxiliary tools, and in particular to a supporting device for ophthalmic surgery. Background Art

[0002] Eyes are the visual organs of humans and animals. They consist of the eyeball and its accessory organs, with the eyeball being the main part. Eyes are the most important organ of human senses, and about 80% of the knowledge in the brain is acquired through the eyes. When performing eye surgery on a patient clinically, the patient's head needs to be supported to cooperate with medical staff for surgical treatment.

[0003] When supporting the patient's head, a professional support and fixing structure is required to fix the patient's head. The traditional support and fixing structure is mainly composed of a support part and a fixing part to fix the patient's head. For example, in the invention patent with the announcement number CN117959130B, a support device for ophthalmic surgery is disclosed. The support device clamps the patient's head by using a clamping plate, so that the patient's head cannot move, which further facilitates the doctor to perform eye surgery on the patient. In addition, by fixing, the patient cannot unconsciously move his head due to fear during the operation, which further improves the probability of medical accidents during the operation and further improves the success rate of the operation. However, although the support device as described above can support the patient's head, when it is used: by using the support plate to continue to move inward, the distance between the clamping plate and the support frame will be further reduced, thereby squeezing the spring 2, and then making the clamping plate fit the patient's head more closely, resulting in the clamping force being unadjustable. When in use, the clamping force can only be judged according to the feeling of the medical staff and the patient, and it is impossible to ensure that the patient's comfort is taken into account when the head is stably fixed; at the same time, there are obvious safety hazards in the adjustment range of the clamping.

[0004] Based on this, the present invention proposes a new type of support device for ophthalmic surgery to achieve stable support and positioning of the patient's head, avoiding excessive support or insufficient support, thereby solving the problems existing in the above-mentioned prior art.

[0051] The head fixing assembly is symmetrically arranged on the support plate 110, and includes two box bodies 220 and a second screw rod 224 fixedly installed on the top of the support plate 110. A second threaded sleeve 221 threadedly connected to the second screw rod 224 is rotatably connected in the box body 220. A second motor 222 is also fixedly installed in the box body 220. The output shaft end of the second motor 222 and the surface of the second threaded sleeve 221 are fixedly connected with meshing bevel gears 223. The end of the second screw rod 224 passes through the second threaded sleeve 221 and is provided with a cylinder body 225. A piston rod 226 is provided in the cylinder body 225. One end of the piston rod 226 passes through the cylinder body 225 and the box body 220 in sequence and is provided with a support portion 227.

[0052] It should be noted that, in this embodiment, through the arrangement of the above-mentioned support frame 100, the head support mechanism 200 and the treatment chair 300, a lying type ophthalmic surgery device with adjustable head lying posture is formed. In specific use: the inclination of the support plate 110 is achieved by the extension and retraction of the electric push rod 120, and the connection between the support frame 100 and the support plate 110 is hingedly connected to adjust the inclination of the support plate 110 according to the surgical requirements, thereby improving the patient's comfort during surgery to meet the different use needs of the patient.

When the slider 2284 enters the annular groove 2282, the pressure alarm 2285 is triggered, and the alarm is automatically triggered, which can warn the medical staff and adjust the equipment in time, thereby avoiding the occurrence of untimely detection and ensuring the safety of the patient.

[0059] As a preferred embodiment, Figure 8 As shown, a limit ring 2251 is provided in the cylinder body 225, and a bearing is provided at the connection between the cylinder body 225 and the moving plate 2283. The limit ring 2251 can limit the final position of the piston rod 226 to avoid excessive movement and ensure the stability and safety of the device during cyclic use.

[0060] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the height adjustment assembly includes a first motor 211 installed on the top of the mounting plate 210, the output shaft of the first motor 211 is fixedly connected to a first screw rod 212, the surface of the first screw rod 212 is threadedly connected to two first threaded sleeves 213, the upper surface of the first threaded sleeve 213 is fixedly connected to a push plate 214, the top end of the push plate 214 is hinged to a push rod 215, and the other end of the push rod 215 is hinged to a headrest 216 that is slidably connected to the support plate.

[0061] It should be noted that, in the present embodiment, the first motor 211 is started, and the first motor 211 drives the first screw rod 212 to rotate, so that the two first threaded sleeves 213 move relative to each other, and drive the two push plates 214 to move relative to each other. The corresponding push rod 215 is used to adjust the height of the headrest 216. The height of the headrest 216 can be adjusted according to the specific situation of the patient and the requirements of the operation, thereby improving the scope of application of the device.

[0062] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the interior of the headrest 216 is a hollow air circulation space, and a plurality of circular holes connected to the air circulation space are provided at the top and bottom of the headrest 216. The normal flow of air can improve the comfort of the contact part between the patient's head and the headrest 216, and avoid the situation of local heat accumulation in the patient during the operation.

[0063] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 , Fig.10 and Fig.11 As shown, the surface of the regulating cylinder 230 is connected with two third connecting pipes 236, and the other end of the third connecting pipe 236 is connected with the gas circulation space. The regulating cylinder 230 is connected with the headrest 216 through the third connecting pipe 236, so that the excess gas in the regulating cylinder 230 can be discharged to achieve the purpose of the preset air pressure value, and the fluidity of the air in the headrest 216 can be increased.

[0064] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 , Fig.10 and Fig.11 As shown, the regulating cylinder 230 and the headrest 216 are connected by a second connecting pipe 235, and a one-way valve 2351 is arranged inside the second connecting pipe 235, through which the gas in the headrest 216 can enter the regulating cylinder 230, while preventing the gas in the regulating cylinder 230 from entering the headrest 216. When the device is reset, the outside air will automatically replenish the gas, and its one-way setting will not affect the preset air pressure value.

[0065] Working principle: The patient lies on the support frame 100, and his head contacts the support plate 110. After adjusting to a suitable angle, the patient's head falls on the headrest 216, and the first motor 211 is started, the first screw rod 212 rotates, and the two first threaded sleeves 213 move relative to each other, driving the two push plates 214 to move relative to each other, and the corresponding push rod 215 is used to adjust the height of the headrest 216; when surgery is required to fix the patient's head, the second motor 222 is started to drive the second threaded sleeve 221 to rotate in place, and the second screw rod 224 is restricted by the slider 2284 and the strip groove 2281, and the second screw rod 224 is rotated in place. 24 will push the cylinder body 225 to move, and synchronously drive the piston rod 226 to move until the support part 227 contacts the ear of the patient's head. When the cylinder body 225 continues to move, the piston at the tail end of the piston rod 226 will squeeze the gas in the cylinder body 225, and the gas enters the adjustment tube 230 from the first connecting pipe 234. The gas squeezes the adjustment plate 233, causing the spring 232 to bend under force. When the adjustment plate 233 moves to the third connecting pipe 236, the excess gas will be transported to the gas circulation space in the headrest 216, so as to achieve constant pressure fixation of the patient's head, and then the patient can undergo ophthalmic surgery.

[0066] It should be noted that the first motor 211, the second motor 222, the Bluetooth speaker 2272, the pressure alarm 2285 and the barometer 240 in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the first motor 211, the second motor 222, the Bluetooth speaker 2272 and the pressure alarm 2285 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0067] Note: The surface of the first screw rod 212 has two sections of external threads in opposite directions, which are threadedly connected to the corresponding first threaded sleeves 213 by means of the external threads, so that when the first screw rod 212 rotates, the two first threaded sleeves 213 will move relative to each other, ensuring the reasonable push of the headrest 216; the Bluetooth speaker 2272 is an existing mature component, which connects the device via Bluetooth to play music.

[0068] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
