Embodiment 1

[0037] A robotic arm for ophthalmic surgery training, the structure of which is as follows Figure 1-Figure 6 As shown, it includes an operating system, and also includes an operating system connected to the operating system. The operating system includes a support device, the support device is provided with a multi-degree-of-freedom mechanical arm 4, and one end of the multi-degree-of-freedom mechanical arm 4 is connected with a training device 5, One end of the training device 5 away from the multi-degree-of-freedom mechanical arm 4 is provided with a surgical device 6; the support device includes a support base 1, and the bottom end of the support base 1 is provided with a plurality of support feet that are axially symmetrical with respect to the support base 1, and the support base 1 is provided with The rotating base 2, the rotating base 2 can be circular or other shapes, the rotating base 2 is provided with a rotating motor 3, the rotating motor 3 is connected with a redu...

Embodiment 2

[0044] A mechanical arm for ophthalmic surgery training differs from Embodiment 1 in that: the inner surface of the arc-shaped hole 7 is provided with rolling teeth, the matching grooves 26 are provided with matching teeth meshing with the rolling teeth, and the two matching grooves 26 They are connected to form meshing grooves; so that the polarizing column 17 and the arc-shaped hole 7 can be matched with a rack and pinion, and the purpose of intelligently reminding the ophthalmologist of an operation error is more accurately realized.

Embodiment 3

[0046] A mechanical arm for ophthalmic surgery training differs from Embodiment 1 in that: the first rotating motor 8 and the second rotating motor 21 are both provided with current sensors, and the current sensors are connected to a current analysis module arranged in a computer; The polarizing upper column 29 and the polarizing lower column 27 are not provided with the auxiliary fixing spring 14 .

[0047]When in use, the rotating motor 3 is activated by operating the operating lever of the support base, and the rotating motor 3 drives the reduction wheel on the center of the rotating base 2 to rotate, which drives the rotating base 2 to rotate slowly, so that the ophthalmic microscope 33 is close to the direction of the patient's eyes; rod; make the multi-degree-of-freedom manipulator arm 4 approach the patient's eye position faster, when the microscope display shows that the ophthalmic microscope 33 is close to the patient's eye position, the ophthalmologist operates the pe...

Abstract

The invention belongs to the technical field of intelligent manufacturing and particularly discloses a mechanical arm for ophthalmic surgery training. The mechanical arm comprises an operating systemand also comprises a surgery system connected with the operating system, wherein the surgery system comprises a support device, a multiple-degree-of-freedom mechanical arm is arranged on the support device, one end of the multiple-degree-of-freedom mechanical arm is connected with a training device, and a surgery device is arranged at the end, away from the multiple-degree-of-freedom mechanical arm, of the training device; the support device comprises a support seat, multiple support legs axially symmetric about the support seat are arranged at the bottom end of the support seat, a rotary baseis arranged on the support seat, a rotary motor is arranged on the rotary base, and the rotary motor is connected with a reduction wheel arranged in the center of the rotary base; and the surgery device comprises a connecting cylinder connected with the training device, an eye opening device is arranged on the connecting cylinder, and an ophthalmic microscope is nested in the eye opening device.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and in particular relates to a mechanical arm for ophthalmic surgery training. Background technique [0002] The limited perception ability of the human hand further restricts the implementation of surgery. In addition, the operating space of ophthalmic surgery is limited to the eyeball with an average diameter of 25mm, the movement of surgical instruments is always constrained by the scleral incision, and the ophthalmologist's slight misoperation It will tear the eyeball and affect postoperative healing. Generally speaking, manual ophthalmic microsurgery has the following difficulties: due to the physiological tremor of the hand, it is difficult for the ophthalmologist to meet the precision requirements of the surgical operation during the operation; the surgical operation force The scale is small, even exceeding the perception limit of the human hand, it is difficult for ophth...
