For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0030] The existing fixation lamp usually sets a fixing clamp which can be clamped on the head crossbar of the ultrasonic examination bed at the bottom of the lamp holder, and the fixation of the fixation lamp is completed by pressing the fixing clamp to open the clamp and clamping on the crossbar under the action of the spring.

[0031] In the related art, the user needs to manually press the fixing clamp during the fixing process. In order to ensure the stability of the fixing clamp clamping the horizontal rod, the spring on the fixing clamp generally has a large elastic force and needs to be forced to be opened by the user. The spring elastic force will act on the user's hand through the fixing clamp. After repeated use, the user's hand will be sore, and after the fixation lamp is used, the fixing clamp also needs to be removed from the horizontal rod, which is time-consuming and laborious.

[0032] In order to solve the problems in the related art to some extent, the embodiments of the present application provide an ophthalmic examination equipment external fixation lamp. A user places the fixation lamp device 1 at the head position of an ultrasonic examination bed, adjusts the position and direction of the fixation lamp head 13 according to the body type and examination posture of the examinee, and then twists the bidirectional screw rod 21 through the knob 212. The bidirectional screw rod 21 is symmetrically provided with threads in opposite directions, and the bidirectional screw rod 21 is symmetrically provided with sliding blocks 211. With the rotation of the bidirectional screw rod 21, the two sliding blocks 211 move in opposite directions, driving the clamping arms 22 to move synchronously to clamp and fix the horizontal rod at the head position of the ultrasonic examination bed. The user then rotates the threaded cover 213 clockwise. The threaded cover 213 is a cover body with internal threads, so that the threaded cover 213 moves horizontally along the bidirectional screw rod 21 after being rotated to abut against the base 11. Under the action of friction, the rotation of the bidirectional screw rod 21 is limited, so that the position of the sliding block 211 is fixed, and the position of the clamping arm 22 is fixed. The entire fixation lamp device 1 is fixed on the horizontal rod at the head position of the ultrasonic examination bed.

[0033] The present application will be described below in conjunction with the drawings and specific embodiments:

[0034] In conjunction with Figures 1-5 , the embodiments of the present application provide an ophthalmic examination equipment external fixation lamp, which comprises a fixation lamp device 1. The fixation lamp device 1 comprises a base 11 provided with a metal hose 12 at the top, the metal hose 12 is provided with a fixation lamp head 13, and the base 11 is provided with a battery box 14. The fixation lamp device 1 is provided with a fixing device 2, the fixing device 2 comprises a bidirectional screw rod 21 rotatably arranged on the base 11, sliding blocks 211 symmetrically arranged on the bidirectional screw rod 21, and the sliding blocks 211 and the bidirectional screw rod 21 are threadedly connected, a knob 212 arranged at one end of the bidirectional screw rod 21, the other end of the bidirectional screw rod 21 is provided with a threaded cover 213, a sliding groove 214 arranged on the base 11, the sliding blocks 211 and the sliding groove 214 are slidably connected, clamping arms 22 arranged at the bottom of the sliding blocks 211, and a plug rod 24 penetratingly inserted into the sliding blocks 211 and the clamping arms 22.

[0035] The user first aligns the slot one 215 on one side of the clamping arm 22 with the sliding block one 211, and aligns the slot two 232 on both ends of the clamping arm 22 with the sliding block two 231, fixes the position of the clamping arm 22 with one hand, and inserts the insertion rod 24 into the insertion hole at the same horizontal position of the clamping arm 22 and the sliding block one 211 with the other hand. Under the elastic force of the spring two 241, the insertion rod 24 is firmly inserted into the insertion hole. After the installation of the clamping arm 22 on both sides is completed, the user places the fixation lamp device 1 at the head position of the ultrasonic examination bed, adjusts the position and direction of the fixation lamp head 13 according to the body type and examination posture of the examinee, and then rotates the knob 212 to drive the bidirectional screw rod 21. The bidirectional screw rod 21 is symmetrically provided with threads in opposite directions, and the bidirectional screw rod 21 is symmetrically provided with the sliding block one 211. With the rotation of the bidirectional screw rod 21, the two sliding blocks one 211 move in opposite directions, driving the clamping arm 22 to move synchronously to clamp and fix the crossbar at the head position of the ultrasonic examination bed. The user then rotates the screw cap 213 clockwise. The screw cap 213 is a cap body with internal threads, so after being rotated, the screw cap 213 moves horizontally along the bidirectional screw rod 21 to abut against the base 11, and under the action of friction, the rotation of the bidirectional screw rod 21 is limited, so that the position of the sliding block one 211 is fixed, the position of the clamping arm 22 is fixed, and the entire fixation lamp device 1 is fixed on the crossbar at the head position of the ultrasonic examination bed. After the fixation is completed, the user can adjust the bending degree of the metal hose 12 to move the fixation lamp head 13 to the patient's side eye, and then turn on the switch on the battery box 14. The battery box 14 is connected through the metal hose 12 and the fixation lamp head 13 to provide power for the fixation lamp head 13. The fixation lamp head 13 can avoid the rotation of the patient's eyes during the examination, reduce the measurement error, and meet the needs of the patient.

[0036] Specifically, the metal hose 12 is a metal shaped hose, which is a composite metal pipe wrapped with metal spring steel wire. It has a spiral pattern on the hollow outside, and a wire of a certain size can be passed through the pipe hole. It can be bent into a certain shape in three-dimensional space and can maintain its shape. The length and size are basically stable when bent. After bending, the hose itself has a certain supporting force to support an object of a certain weight. The supporting force is controllable within a certain range.

[0037] In some embodiments, the sliding block one 211 is an I-shaped. The sliding block one 211 and the sliding groove one 214 have a small width in the sliding connection part, so the sliding groove one 214 is relatively narrow, which can reduce the risk of the bidirectional screw rod 21 being stuck due to the entry of bulky objects such as gauze into the base 11.

[0038] In some embodiments, the clamping arm 22 is provided with a slot one 215, and the bottom of the sliding block one 211 is inserted into the slot one 215. The slot one 215 is provided to insert the clamping arm 22 and the bottom of the sliding block one 211, which facilitates the subsequent disassembly of the clamping arm 22 for repair or replacement.

[0039] In some embodiments, the clamping arm 22 is provided with a slot two 232, the base 11 is provided with a sliding groove two 23, the sliding groove two 23 is slidably provided with a sliding block two 231, and the sliding block two 231 and the slot two 232 are inserted. The sliding block two 231 and the sliding groove two 23 improve the stability of the clamping arm 22 during movement, and the sliding block two 231 and the sliding block one 211 are in the same horizontal position, thereby providing positioning for the clamping arm 22 during installation.

[0040] In some embodiments, the inner side wall of the clamping arm 22 is provided with a spring one 221 and a plate body 222. The plate body 222 is abutted against the contact surface under the elastic force of the spring one 221, thereby enhancing the tightness of the entire fixing device 2 and the clamping surface.

[0041] In some embodiments, the outer surface of the plate body 222 is provided with a rubber layer. The rubber layer is soft, has good deformability and good friction, can improve the friction between the plate body 222 and the contact surface, and make the entire device more stable after being fixed.

[0042] In some embodiments, the insertion rod 24 is provided with a spring two 241. After the insertion rod 24 is inserted with the sliding block one 211 and the clamping arm 22 under the elastic force of the spring two 241, the insertion rod 24 will not be easily pulled out or fall off, thereby improving the stability of the entire device during use.

[0043] In some embodiments, the base 11 is symmetrically provided with two placing grooves 25. The two placing grooves 25 are respectively provided with an alcohol cotton ball jar for disinfecting the fixed light head 13 and a anesthetic bottle for use on the eyeball of a patient, and are arranged above the placing grooves 25 to facilitate the medical staff to take them.
