Problems solved by technology

The curved needle is bent by external force on the basis of the straight needle. Due to the different dimensions of the curved needle, such as diameter, radian, and length, it is difficult to automate the bending process of the curved needle. At present, most suture needle manufacturers in China The bending process is manual bending or semi-automatic bending (manual feeding, mechanical impact bending), manual feeding has problems such as low positioning accuracy, large randomness, high scrap rate, high labor intensity, and low production efficiency. There are also many security risks
The pros and cons of products mostly depend on the proficiency of workers, which limits the scale of production and production efficiency.

Abstract

The invention discloses a fully automatic bending machine for medical suture needles, comprising a frame body (1), characterized in that: the frame body (1) is provided with a power drive device (2), a bending device (3 ), the automatic feeding device (4) and the plane deviation correction device (5). The invention effectively solves the problem that the existing medical suture needles with radians are bent manually or semi-automatically. The product quality and production efficiency of the curved needles mainly depend on the proficiency of the workers, which makes the production scale and production efficiency more restricted. Big restrictions.

Description

technical field [0001] The invention relates to the technical field of medical equipment automatic production equipment, in particular to a fully automatic bending machine for medical suture needles. Background technique [0002] Suture needle (needle), referred to as suture needle, is an instrument for suturing various tissues. Clinically, according to whether there is a radian between the needle tip and the needle tail, the suture needles are divided into straight needles, semi-curved needles and curved needles. Curved needles are the most widely used clinically and are suitable for suturing small or deep tissues. According to the curvature of the arc, it is divided into 1 / 2, 1 / 4, 3 / 8, 5 / 8, etc. Almost all tissues and organs can be sutured with loopers of different sizes and curvatures. Therefore, the demand for loopers is the largest. . The curved needle is bent by external force on the basis of the straight needle. Due to the different dimensions of the curved needle,...
