Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

A handheld fundus imaging apparatus as shown in fig. 1-4 comprises a handheld fundus camera and a support movably arranged at the lower end of the handheld fundus camera; the handheld fundus camera comprises a handle 1, a fundus lens 2 and a display screen 3; a battery is arranged in the handle 1, an image sensor (not shown) for converting an optical signal of an acquired image into a digital signal and a signal processing unit (not shown) are arranged between the handle 1 and the fundus lens 2, and the image sensor and the signal processing unit are electrically connected with the battery and the display screen 3; the fundus lens 2 includes an eyepiece, a photographing lens module, and a diaphragm. The handheld fundus camera of the present embodiment is an existing device, such as a handheld fundus camera manufactured by suzhou mini-qing medical instruments ltd.

The supporting piece comprises a sucker 4, a swinging rod 5, a tension spring 6, a bearing 7 and a clamping seat; the lower end of the swing rod 5 is hinged with the upper end of the suction cup 4 through a hinge ball 9; the upper end of the swinging rod 5 is hinged with a connecting block 8 through another hinge ball 9; the upper end of the connecting block 8 is provided with a bearing 7 with a horizontal end surface; a plurality of tension springs 6 are arranged along the circumferential direction of the sucker 4, the upper ends of the tension springs 6 are connected with the swing rod 5, and the lower ends of the tension springs 6 are detachably connected with the sucker 4; the clamping seat comprises a cylinder body 10, a gland 11, a rubber ring 12, a spring 13, a slide bar 14, a slide block 15 and a slide groove 16; the upper end of the cylinder body 10 is an open end and is provided with a gland 11, and the lower end of the cylinder body 10 is connected with the bearing 7; the gland 11 is provided with a through hole communicated with the cylinder 10; the rubber ring 12 is arranged at the through hole and is matched with the handle 1, the inner diameter of the rubber ring 12 is gradually reduced from top to bottom, and a plurality of horizontal annular rubber bands 17 are arranged on the inner wall of the rubber ring 12; the spring 13 has a plurality of rubber rings 12 arranged between the cylinder 10 and the pressing cover 11 along the circumferential direction of the cylinder 10, the upper end of the spring 13 is connected with the pressing cover 11, and the lower end of the spring 13 is connected with the cylinder 10.
