Description

Automatic Sealing Device {AUTOMATICAL SUTURE APPARATUS}

The present invention relates to a device for suturing a coronary organ (such as a blood vessel, large intestine or small intestine), and more particularly to an automatic closure device using a suture ring.

Free flaps are performed to reconstruct soft tissue defects or functional and aesthetic deficiencies in various parts of the body, and remarkable progress has been made since successful glass flap surgery by Daniel and Taylor in 1973. Free flap is one of the most important procedures. Vascular sutures with micro sutures require a lot of training time to complete the technique of vascular sutures while reducing damage to the vessel wall. There have been many disadvantages such as risk of complications. To overcome these shortcomings, since Nakayama et al. Developed a method for vascular closure using microtubules in 1962, continuous animal experiments and clinical results have been reported abroad. Komei Nakayama et al. First introduced the use of suture rings in vascular sutures during esophageal reconstruction, and continued development of mechanical sutures.

The advantages of such sutures are, firstly, not as much training time as is necessary for acquiring accurate and skilled techniques, such as when sutures are used, and secondly, the time required for vascular closure itself is 2-3 minutes. Third, the postoperative follow-up result is not inferior to the microvessel suture using the suture, and the fourth can be easily corrected even when a large difference in the diameter of the recipient and the donor vessel occurs. There are several advantages, such as the ability to suture easily even in limited (narrow) spaces and deep human bodies.

Pulling the lever 70 toward the rear, the first and second drive shafts (42, 52) are moved to the rear in the stopped state of the first and second driven shaft (20, 30), as described above, The first and second drive grooves move rearward together with the first and second drive shafts 42 and 52. Thus, the first and second driven shaft projections move forward along the first and second driving grooves, respectively. In this case, the movement of the first and second driven shafts 20 and 30 may be limited by the inner wall surface (the surface on which the insertion groove 66 is formed) of the case 60 to be described later.

For example, as illustrated in FIG. 5, the first driven shaft 26 located in the first lower groove 44a may gradually move up along the first inclined groove 44b (FIG. 5). The first upper groove 44c is reached. At this time, as the first driven shaft protrusion 26 moves upward, the first driven shaft 20 rotates in the first drive shaft 42, and as shown in FIG. 6, the first driven shaft 20 is Rotate clockwise. Like the first driven shaft 20, the second driven shaft 30 rotates in the second drive shaft 52, and the second driven shaft 30 rotates counterclockwise. At this time, the rotational displacement θ is determined by the distance between the first lower groove 44a and the first upper groove 44c.

As shown in Fig. 1, before the sealing is made, the sealing rings R1 and R2 are inserted into and fixed to the heads 21 and 31, and the sealing rings R1 and R2 are generally located on the same plane. In addition, the flat surfaces of the first and second driven shafts 20 and 30 are generally located on the same plane. This state is called 'release position'. When the sealing rings R1 and R2 and the first and second driven shafts 20 and 30 are in the 'disengaged position', the driven shaft protrusion 26 is located on the lower groove 44a.

Subsequently, as described above, when the first and second driving shafts 42 and 52 move rearward, the driven shaft 20 rotates while the driven shaft protrusion 26 moves along the inclined groove 44b. When the driven shaft protrusion 26 reaches the upper groove 44c, the rotation of the driven shaft 20 is completed.

As shown in FIG. 6, the first driven shaft 20 rotates clockwise, and the second driven shaft 30 rotates counterclockwise. As a result, the sealing rings R1 and R2 are positioned to face each other, and the flat surfaces of the first and second driven shafts 20 and 30 face each other. This state is called 'standby position'. When the sealing rings R1 and R2 and the first and second driven shafts 20 and 30 are in the 'standby position', the driven shaft protrusion 26 is located on the upper groove 44c.

On the other hand, unlike the present embodiment, when the 'release position' and 'standby position', the relative position of the suture ring (R1, R2) and the first and second driven shaft (20,30) may be different. For example, when the sealing rings (R1, R2) are in the 'release position', the sealing rings (R1, R2) can achieve a predetermined angle.

As shown in FIG. 1, the automatic sealing device includes a case 60. 8 is a perspective view showing the case shown in FIG.
