Microsurgery auxiliary device

Abstract

The invention discloses a microsurgery auxiliary device. The microsurgery auxiliary device comprises a lens body and a glasses-free 3D displayer, wherein an imaging unit is arranged in the lens body,and comprises a large objective lens set, zoom lens sets, first lens cone objective lenses and photosensitive elements, and the large objective lens set, the zoom lens sets, the first lens cone objective lenses and the photosensitive elements are sequentially located on the same observation light path. The large objective lens set comprises at least one positive lens set and at least one negativelens set, the positive lens sets and the negative lens sets share the same optical axis, the distance between the positive lens sets and the negative lens sets is adjustable, the glasses-free 3D displayer is connected with the photosensitive elements, the distance between the glasses-free 3D displayer and an observer is 400-1,200 mm, and the range of the visual angle of the glasses-free 3D displayer is not less than 120 degrees. According to the microsurgery auxiliary device, the observer can directly conduct surgery operation by observing the glasses-free 3D displayer, the device is simple inoverall structure and small in system delay, the fixing mode of the glasses-free 3D displayer can be selected according to field requirements, the fixing structure is simple and reliable, an observation component can be additionally arranged when necessary, and traditional visual observation is achieved.

Description

Technical field[0001]The invention relates to the technical field of medical equipment, in particular to a microsurgery auxiliary device.Background technique[0002]Microsurgery is a delicate operation performed with the help of magnifying equipment. When the operation is performed under a traditional optical operating microscope, the tissue is magnified, not only can see the small tissues that are invisible to the naked eye during the operation, but also has a three-dimensional effect, which is beneficial to the surgeon Accurately dissect, cut and suture various tissues. However, even surgeons who are experienced in suturing blood vessels with the naked eye, without special training, are still very unaccustomed to microsurgery at the beginning of the operation. Hand-eye coordination often occurs, which affects the operation under the microscope. Therefore, it is necessary to It takes a period of training and adaptation process to skillfully perform operations under the operating micr...

Problems solved by technology

This solution also requires complex data processing of the collected images, which is difficult to meet the low-latency requirements of microsurgery. In addition, an imaging system with eight optical paths is required, which has a complex structure and high manufacturing costs.
