3 is a state view of a stitching needle accommodated in a holder before cap coupling according to the present invention,

The cap 230 is formed to have the same outer diameter as the outer diameter of the holder 200 and has a threaded portion 235 formed at a position where it contacts the holder 200 to be connected to the holder 200, A threaded portion is also formed at the position of the hole 201 of the base plate 200.

The cap hole 231 of the cap 230 is a space for receiving the sealing needle 310 so that the size of the sealing needle 310 is smaller than that of the sealing needle 310 so that the sealing needle 310 is elastically installed at the cap hole 231 And is formed to have the same diameter as the hole 201 of the holder 200.

The bent end of the suturing needle 310 received in the hole 2010 of the holder 200 is hooked on the hole 201 and the bent end of the suture needle 310 is exposed to the outside of the holder 200.

4 shows a state in which the bent state of the suturing needle is temporarily deformed when the cap is coupled to the holder of the present invention. The cap hole 231 of the cap 230 receives the needle 310 for sealing, In order to guide the supply of the sewing needle 310 to the cap hole 231 while both ends of the sewing needle 310 and the curved portion of the needle 310 are inserted into the cap hole 231 in the process of receiving the sewing needle 310, And is received in a resiliently inserted state at the cap hole (231).

When the sealing needle 310 is supplied to the sealing portion by the slider 212 in forming the cap hole 231, the pointed needle of the needle 310 is not caught on the surface of the cap hole 231 The diameter d of the opening side of the cap hole 231 is set to be larger than the diameter D of the hole 200 of the holder 200 as shown in FIG. 4 so that the cap hole 231 is inclined Do.

The holder 200 and the cap 230 are formed of a transparent material so that the mounting state of the suture 300, the needle 310 and the slider 212 located in the hole 210 can be confirmed.

In the laparoscopic surgical suture apparatus of the present invention constructed as described above, the loop 303 is previously knotted to the suture 300 as shown in FIG.

The suture 300 is inserted into the hole 201 of the holder 200 and the suture 300 is inserted into the hole 201 when the suture 300 and the suturing needle 310 are inserted into the hole 201, The bent end of the needle 310 is caught in the hole 201 of the holder 200 as shown in Figure 3 and the other end of the needle 310 is put in the hole 201 so as to be exposed to the outside of the holder 200 .

In this state, the holder 200, the cap 230, and the plunger 210, in which the suture thread 300 and the suturing needle 310 are stored, are separated from each other until the suturing order is established in the laparoscopic surgery.

At this time, the state of the inside of the holder 200 and the cap 230 is seen by the characteristic of the transparent material.

During the laparoscopic surgery, the screw portion 235 of the cap 230 is screwed into the screw portion of the holder 200 when the surgical site is closed.

When the cap 230 is screwed into the holder 200, the sealing needle 310 is inserted into the cap hole 231 by the surface of the cap hole 231 in the process of inserting the sealing needle 310 into the cap hole 231, The suture needle 310 is formed of a material having a good elastic returning force. When pressure is externally applied, a repulsive elastic force is relatively generated, (231), the suturing needle (310) is received in a state ready to return to the shape before insertion.

The holder 200 in which the sealing needle 310 is resiliently assembled by the cap 230 is inserted into the inner diameter 110 of the trocar 100 inserted into the abdominal wall A and the opening of the cap 230 Close to the laparoscopic surgical site.
