AI Technical Summary

Technical Problem

When removing the stapler stapler, the existing nail taker cannot accurately define the position of the stapler, resulting in a possible deflection when the stapler is removed.

Method used

A nail picker is designed including a first and second mating arm connected to the rotary column. The end of the second mating arm is provided with a support semicircle ring. Through the cooperation of the point pressing column and the stable column, the support semicircle ring is ensured to accurately pass through the intermediate position of the staple staple, and the position of the staple is defined by the defining rod to avoid deflection.

Benefits of technology

By accurately defining the position of the staple, ensuring that the staple will not deflect during the removal process, improving the efficiency and accuracy of the nail taker.

Abstract

The nail extractor comprises a first forceps arm and a second forceps arm which are connected through a rotary column, a pressing forceps head is arranged at the end of the first forceps arm, a supporting semicircular ring opposite to the pressing forceps head is arranged at the end of the second forceps arm, a first connecting rod is arranged on the second forceps arm, and a second connecting rod is arranged on the second forceps arm. A stabilizing column is arranged at the end, away from the second clamp arm, of the first connecting rod, a limiting rod is arranged on the stabilizing column, and the outer side of the first connecting rod is sleeved with a moving cylinder. The point pressing column penetrates through the middle position of the suturing nail, a certain gap is formed between the point pressing column and the skin, the supporting semicircular ring can penetrate through the point pressing column easily, the stabilizing columns are distributed on the two sides of the suturing nail, the supporting semicircular ring can accurately penetrate through the middle position of the suturing nail, and in the suturing nail taking-out process, the suturing nail penetrates through the position between the two limiting rods which are distributed in a staggered mode. The suturing nail is limited by the limiting rod, so that the suturing nail is prevented from being deflected when being taken out, and the nail taking device is provided with a design for limiting the suturing nail.
