Episome taking-out device

Abstract

The invention discloses an episome taking-out device. The episome taking-out device comprises a mesh bag, a connecting device and an adjusting handle, wherein the mesh bag comprises a mesh surface anda mesh surface framework; the edge of the mesh surface is connected with the mesh surface framework; the connecting device comprises a guide sleeve and a connecting rod arranged in the guide sleeve in a sliding mode; one end of the connecting rod is connected to the mesh surface framework; and the adjusting handle is connected to the connecting rod and used for driving the connecting rod to slidein the guide sleeve. The connecting rod slides to drive the mesh surface framework to slide into or out of the guide sleeve so as to adjust the size of a mesh opening of the mesh bag exposed out of the guide sleeve, the number of times of capturing episomes through operation forceps is reduced, the risk that the episomes fall off in capturing and taking-out processes is reduced, and the operationdifficulty is reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a device for removing loose bodies. Background technique [0002] Loose bodies move in joints, also known as joint rats. In joints such as knees or elbows, some pressured convex surfaces of epiphyses can undergo ischemic necrosis and exfoliation under repeated external forces, and free in the joints, which is called exfoliation. Osteochondritis (joint loose body), and synovial metaplasia on the free body, which can form chondrocytes or bone cells to continue to grow. In the prior art, surgical clamps are often used to capture loose bodies. Due to the smooth surface of loose bodies, multiple captures are required when using surgical clamps, and surgical clamps may cause damage to other tissues when they are opened and occluded, and the free bodies Factors such as different shapes, sizes, and smooth surfaces of the loose body often cause the loose body to fall off during the remov...

In the prior art, surgical clamps are often used to capture loose bodies. Due to the smooth surface of loose bodies, multiple captures are required when using surgical clamps, and surgical clamps may cause damage to other tissues when they are opened and occluded, and the free bodies Factors such as different shapes, sizes and smooth surfaces of the body often cause the loose body to fall off during the removal process of the loose body held by surgical clamps, which increases the difficulty of the operation.
