Embodiment 1

[0037] A mechanical arm for eye surgery training, its structure is like Figure 1-Figure 6 As shown, the operating system is included, and the operating system is connected to the operating system. The operating system includes a support device. The support device is provided with a multi-degree-of-freedom manipulator 4, and one end of the multi-degree-of-freedom manipulator 4 is connected with a training device 5. The 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 axisymmetric to the support base 1, and the support base 1 is provided with Rotating base 2. Rotating base 2 can be circular or other shapes. Rotating base 2 is provided with rotating motor 3, rotating motor 3 is connected with a reduction wheel arranged on the center of rotating base 2, rotating motor 3 i...

Embodiment 2

[0044] A mechanical arm for ophthalmic surgery training. The difference from Embodiment 1 is that: the arc-shaped hole 7 is provided with rolling teeth on the inner surface, and the matching grooves 26 are provided with matching teeth that mesh with the rolling teeth. Two matching grooves 26 They are connected to form a meshing groove; the polarizing column 17 and the arc-shaped hole 7 are matched with a gear and rack, which can more accurately realize the purpose of intelligently reminding the ophthalmologist of operating errors.

Embodiment 3

[0046] A mechanical arm for ophthalmic surgery training. The difference from the first embodiment is that: the first rotating motor 8 and the second rotating motor 21 are both equipped with current sensors, and the current sensors are connected with the current analysis module arranged in the computer; No auxiliary fixing spring 14 is provided on the upper polarization post 29 and the lower polarization post 27.

[0047] When in use, start the rotating motor 3 by operating the operating lever of the support base. The rotating motor 3 drives the reduction wheel on the center of the rotating base 2 to rotate, and drives the rotating base 2 to slowly rotate so that the ophthalmic microscope 33 is close to the direction of the patient's eyes; operate the mechanical arm to operate Lever; makes the multi-degree-of-freedom mechanical arm 4 quickly approach the patient’s eye position. When the microscope display shows that the ophthalmic microscope 33 is close to the patient’s eye, the op...

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 specifically relates to a mechanical arm for eye surgery training. Background technique [0002] The limited perception of human hands further restricts the implementation of the operation. In addition, the operating space of eye surgery is limited to the eyeball with an average diameter of 25mm, and the movement of surgical instruments is always constrained by the scleral incision, and the ophthalmologist slightly misoperation It will tear the eyeball and affect postoperative healing. In general, manual ophthalmic microsurgery has the following difficulties: due to the physiological tremor of the hand, it is difficult for the ophthalmologist to meet the accuracy requirements of the surgical operation during the operation; surgical operation force The scale is small, even exceeding the perception limit of the human hand. It is difficult for ophthalmologists to accurately perceive...
