AI Technical Summary

Technical Problem

The existing bipolar tweezers are prone to deviation in the alignment of the tweezers during assembly, resulting in low adjustment efficiency and poor accuracy. The tweezers are prone to deform after standing, resulting in the alignment of the tweezers when the product leaves the factory, but are easily misaligned during use, affecting the surgical effect.

Method used

An alignment device for tweezers is designed, including a bracket body, adjustment assembly, scale plate and camera. Through the real-time imaging picture feedback from the camera, the rotating stage and the mobile stage drive clamp firmware are used to adjust the multi-position in the three-axis direction of X, Y, and Z to achieve accurate alignment of the tweezers.

Benefits of technology

The efficiency and accuracy of tweezer sheet alignment is improved, the tweezer tip is avoided to deform after being left to stand, the structure of the bipolar tweezer body is ensured, and the problems of tweezer tip alignment deviation and insufficient adjustment accuracy in the prior art are solved.

Abstract

The present invention relates to the technical field of medical instrument adjustment, and provides an alignment device for tweezers and a control method thereof. The device comprises a support body, an adjustment assembly arranged on the support body for adjusting a bipolar tweezers body, a scale plate arranged on the support body and close to the tweezers tip of the bipolar tweezers body, a first camera arranged on the support body and perpendicular to the center just above the scale plate along the Z-axis direction, and a second camera arranged on the support body and parallel to the center of one side of the scale plate along the X-axis direction. The first camera and the second camera are used to take real-time imaging pictures of the bipolar tweezers body, and the adjustment assembly is controlled to drive the bipolar tweezers to be adjusted to be adjusted in the direction of a measurement reference line, and multiple positions are adjusted along the three axes of X, Y and Z respectively until they overlap. The adjustment efficiency is high, and no deformation occurs to the two tweezers during the entire adjustment process, and no internal stress exists, so as to ensure the adjustment accuracy and structural stability of the bipolar tweezers body.
