Embodiment Construction

[0029] The present invention is described in detail below in conjunction with accompanying drawing:

[0030] Such as figure 1 As shown, a surgical device for the retina of the eye includes a driving unit, a film gripper 1 is selected as the gripping device, a first sensor 2, a bracket 3, a third driving motor 4, a first driving motor 5, a second Drive motor 6 , displacement platform 3 b and second sensor 8 . Generally speaking, the film gripper 1 is directly connected to the driving unit or connected through a transmission mechanism to drive the gripper to move, the retina is gripped by the film gripper 1, and the first sensor 2 is connected to the connected to the gripper 1, the displacement and rotation of the membrane gripper 1 and / or the first sensor 2 are controlled by the drive unit to grip the retinal tissue, and the first sensor 2 senses the The reaction force received by the membrane gripper 1 is used to judge whether the gripper touches the retinal tissue of the hu...

Abstract

The invention discloses an eye retina operating device. The eye retina operating device comprises a drive unit, a clamping device and a mechanical sensor. The clamping device is used for clamping human body tissue. The mechanical sensor is used for sensing counter acting force of the human body tissue on the clamping device in order to judge whether the clamping device makes contact with the humanbody tissue or not. The mechanical sensor is connected with the clamping device, and the drive device is used for directly driving the clamping device and / or the mechanical sensor to be movably arranged or driving the clamping device and / or the mechanical sensor to be movably arranged through a transmission mechanism. The eye retina operating device is simple in structure and high in precision, the control precision of the eye retina operating device can be controlled at about 0.01 mm, and actual operation is facilitated.

Description

technical field [0001] The present invention relates to a surgical device for the retina of the eye. Background technique [0002] The retina is an important light-sensitive tissue on the inner surface of the eye, and the macula is the most critical area for visual function. A variety of diseases, such as epiretinal membrane, macular hole, etc., can lead to decreased vision. For the above diseases, stripping of proliferative membrane or internal limiting membrane is required, but membrane stripping has high requirements for the accuracy of surgical operation, and misoperation can lead to serious tissue damage. [0003] Currently, there are several existing ophthalmic surgical devices or devices. For example, the application number is 93237070.5 in the ophthalmic surgery ball tweezers, the tubular handle of the ophthalmic surgery ball tweezers is provided with a handle, and the rear end of a pair of tweezers has a thin rod-shaped inner core, which passes through the sleeve ...
