Abstract

The present invention relates to a suture needle used in laparoscopic surgery.
Conventional laparoscopic suture needles include straight or ski type, which are easy to insert into thin conduits, but the suture of the internal incision in a narrow space is very difficult and requires skillful techniques, and it is difficult to make detailed sutures. There was this.
The present invention has been made for the purpose of solving the above problems by making it possible to use a semi-dal suture acupuncture needle that was not available in the prior art.
In order to achieve the above object, a thin rod 1 made of a shape memory alloy material is processed into a straight suture needle 2, which is rolled into a half moon shape to form a half moon suture needle 3, and this is converted into a mold 4 Laparoscope with heat treatment to heat shape to make shape memory transformation in the range of 25 to 40 degrees Celsius in fixed state so that half moon shape is stored as high temperature shape, straighten suture needles stored in high temperature shape, and heat treatment to remember straight low temperature shape. Surgical suture needles.
The suture needle according to the above constitution is inserted into the conduit in a straight line by performing a low temperature shape memory transformation at room temperature, and after insertion, the suture needle is changed into a half moon shape by high temperature memory transformation by body temperature to facilitate suture surgery. .

Description

Laparoscopic Suture Needle

Since this is an open matter, no full text was included.

1 is a type of suture needle used in conventional laparoscopic surgery, double (a) is straight (b) ski type,

2 is a diagram of the suture needle applied to the present invention, (a) form at room temperature (b) state recovered to half moon shape by body temperature,

3 is a manufacturing process diagram of the present invention (a) the step of processing the shape memory alloy into the bar (b) the step of processing the bar into a straight suture needle (c) the step of bending the straight suture needle into a half moon ( D) the step of storing the half moon shape by heat treatment in the state fixed by the mold (e) the heat treated state in the half moon shape (bar) the straight suture of the half moon into a straight line (g) the straight suture needle The step (memory) of storing the linear shape which is the secondary shape by fixing to the state is completed with a straight suture needle.

Claims (2)

  1. The thin bar (1) made of shape memory alloy material is processed in the form of a straight suture (2), and it is bent into a half moon shape to form a half moon suture needle (3), which is fixed at 25 degrees Celsius with the mold (4) fixed. The heat treatment is performed to induce the shape memory transformation in the range of 40 degrees, so that the half moon shape is stored as a high temperature shape, and the straight needle is held in a straight line to keep the high temperature shape memorized stitches. Laparoscopic suture needles, characterized in that configured to change in shape.
  2. The method of claim 1, wherein the suture needle, which has been completed in a straight shape, is fixed with a mold, and is subjected to low temperature heat treatment so as to cause a shape memory transformation at room temperature so that the straight shape is stored in a low temperature shape so that the straight shape is changed into a straight shape at room temperature and ranges from 25 to 40 degrees Laparoscopic suture needles, characterized in that configured to change from half moon shape.
    ※ Note: The disclosure is based on the initial application.
