Microscopic positioning and separating apparatus

Abstract

The invention provides a microscopic positioning and separating apparatus. The microscopic positioning and separating apparatus comprises a machine frame, a moving mechanism, a conveying mechanism, aconnector and a replacing-driving mechanism; the moving mechanism is connected to the machine frame, and can realize three-dimensional movement on the machine frame; the conveying mechanism is connected to the machine frame, and is used for conveying a capture nozzle to a predetermined butt-joint position; the connector is connected to the moving mechanism, and is capable of sliding relative to the moving mechanism; the connector is used for connecting with the capture nozzle; the moving mechanism drives the connector to be pre-connected with the capture nozzle; the replacing-driving mechanismis connected to the machine frame; and the replacing-driving mechanism pushes the connector to slide along the moving mechanism so as make the connector to get close to the capture nozzle, thereby realizing butt-joint between the connector and the capture nozzle. The microscopic positioning and separating apparatus is capable of realizing automatic replacement of the capture nozzle, so that degree of automation of the microscopic positioning and separating apparatus is improved.

Description

technical field [0001] The present application relates to the technical field of micropositioning, in particular to a micropositioning separation device. Background technique [0002] In biotechnology and medical research, it is often necessary to select and separate microbody samples according to specific criteria. In general, micro-body samples are extracted and pushed through the capture nozzle (such as a needle, etc.) and the hydraulic system connected to the capture nozzle. The hydraulic system generates negative pressure at the capture nozzle to extract the micro-body sample into the capture nozzle. The hydraulic system Positive pressure is generated at the capture nozzle to expel microscopic samples in the capture nozzle. In order to prevent contamination of the discharged micro-body samples, the capture nozzle is generally used for one-time use, that is to say, after the extraction and pushing of a micro-body sample is completed, the capture nozzle needs to be repla...

AI Technical Summary

Problems solved by technology

The existing micropositioning and separation devices usually use manual replacement of the capture nozzle, resulting in a low degree of automation of the micropositioning separation device, which makes it difficult to achieve efficient separation and extraction of microscopic samples, and manual replacement of the capture nozzle has a high cost to the operator. The proficiency requirements require special training to ensure the operator's installation techniques and strength. The wrong installation method is not only difficult to ensure the realization of functionality but also the risk of equipment damage, and it is difficult to achieve efficient separation and extraction of microscopic samples.
