Bending device for medical suture needle production and bending method thereof

Abstract

The invention discloses a bending device for medical suture needle production and a bending method thereof.The bending device comprises the ground, an operation table, a first conveyor, a second conveyor, a lifting oil cylinder and a cooling pond, the bending device is arranged on one side of the rear end of the operation table, and an annular conducting ring is fixedly connected with the ground through bolts. According to the bending device for producing the medical suture needle, the second electromagnet is used for adsorbing an iron block on the upper mold, so that the upper mold and the lower mold are temporarily fixed together, and the time for shaping the suture needle by the upper mold and the lower mold is prolonged; the arranged heater is used for heating the suture needle in the shaping process, the possibility that the suture needle recovers deformation after being shaped is reduced by increasing the temperature of the suture needle, and the arranged cooling pool is used for cooling the heated suture needle and further shaping the suture needle, so that the bent suture needle keeps deformation; and the qualified rate of finished products of the suture needle is improved.

Description

technical field [0001] The invention relates to the technical field of medical device production, in particular to a bending device for medical suture needle production and a bending method thereof. Background technique [0002] Medical suture needles are mainly used for surgical suturing. Most of them are made of stainless steel wire drilled or slotted at the end of the needle. The surface has been polished and electrolytically treated, and should be very smooth; needle types are divided into: round needles, angle needles, Shovel needles, straight needles, etc., the radian is divided into: 1 / 2, 3 / 8, etc. according to actual needs; the production process is very complex, and it is a high-tech product. Fine drilling even uses laser drilling technology. However, the existing medical The bending device used for the production of suture needles is easy to recover a certain deformation under the influence of its own material in the one-time bending process, which easily leads to ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a bending device for producing medical suture needles and a bending method thereof, so as to solve the problem that the existing bending device for producing medical suture needles proposed in the above-mentioned background technology is difficult to bend and produce medical suture needles. Among them, the one-time bending treatment will easily cause the medical suture needle to recover a certain deformation under the influence of its own material, which will easily lead to the curvature of the produced medical suture needle not meeting the production standard, which reduces the qualified rate of the bent product.
