Medical Observation Device Base Section Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical observation devices, particularly those with optical microscope sections, face challenges in size and weight due to the need for counterweights and integrated control and operation sections, which restrict movement and increase space occupancy in operating rooms.
Innovation Solution
A medical observation device with an electronic imaging type microscope section, where the operation section is positioned at the base section rather than the holding section, allowing for independent adjustment of the operation section's position and orientation while maintaining the microscope section's position and attitude, thereby reducing device size and improving surgical convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the operation section is integrated with the holding section in optical type observation devices, then the device size is reduced, but the operation section interferes with the movable range of the counterweight and restricts operator convenience
Solution Approach 1:
The observation device is divided into separate functional modules: the holding section (balance arm with counterweight) and the operation section (control substrate and touch panel) are independently positioned. The operation section is mounted on the base section rather than the holding section, allowing each component to operate independently without interference. This segmentation resolves the contradiction by enabling compact overall device size while ensuring the operation section does not obstruct the counterweight's movement range.
2Ease of operation
If the holding section is formed to have sufficient length for overhead style observation, then observation capability is improved, but the counterweight size increases significantly
Solution Approach 1:
The operation section is repositioned from the vertical holding section to the horizontal base section, utilizing a different spatial dimension. This dimensional transition allows the holding section to maintain its sufficient length for overhead observation without requiring an oversized counterweight, as the operation section no longer adds to the vertical mass that the counterweight must balance.
3Ease of operation
If the control section and operation section are arranged outside the movable range of the counterweight, then counterweight movement is not interfered with, but the entire device size increases and occupies more operating room space
Solution Approach 1:
The operation section is merged with the base section, combining the support function and the control function into a single integrated structure. This merging allows the device to occupy minimal space in the operating room while ensuring the operation section is positioned outside the counterweight's movable range, thus maintaining freedom of movement without increasing overall device footprint.

AI summary
A medical observation device that includes a microscope that images a surgical site, a holding section that holds the microscope, a base section to which the holding section is connected, and an operation section that receives operating input, the operation section being provided at the base section, the holding section being configured as a balance arm provided with a counterweight, when the base section is viewed from an upper side of the medical observation device, the base section having a first area inside a movable range of the counterweight and a second area outside the movable range of the counterweight, the base end of the holding section being connected to the base section at a location in the first area, and the operation section being arranged at another location in the second area.
