Description

Medical suture {A MEDICAL SUTURING DEVICE}

The present invention relates to a medical suture device, and more specifically, by configuring a needle for suturing an incised surgical site in a rotary type, the device can be miniaturized to enable suturing of a narrow area by shortening the movement path of the needle during suturing, The present invention relates to a medical suture that increases the efficiency of suturing so that a procedure can be performed quickly and accurately.

There are many cases where skin incision is essential in various internal surgery, and in some cases, the incised skin tissue is sutured.

In addition, when not only skin tissue but also soft tissue such as muscle, fat, and internal organs are torn or cut, a suture procedure is required to restore them.

In order to suture the incised skin, it is common to use a needle and a thread.

Needles and threads used at this time are called suture needles and sutures in the medical field.

In addition, when suturing body tissue, a forcep and a needle holder are provided so as not to grab the tissue directly by hand, and the tissue and the suture needle are respectively gripped and sutured using the forceps and forceps do.

In recent years, medical staplers using iron cores have been used for skin suturing, but these medical staplers are often used for emergency purposes, so the scope of use is not widely spread.

In addition, the medical stapler is provided to be mainly used for one-time use, fixes an iron core for suturing the skin to an incised tissue, and is provided to remove the iron core using a remover when the skin tissue is sutured.

Accordingly, the medical stapler is intended to prevent the incised skin from opening during skin suturing or to easily insert a suture thread into a needle, and is merely a tool for facilitating suturing of the incised skin.

On the other hand, one of the important factors in skin suturing is a suturing technique in a certain pattern.

If the stitch marks are irregular, the healing time of the wound may be delayed, and after the wound is completely healed, it may not only look bad, but also cause a problem of skin bursting.

However, when a medical practitioner directly sews a suture through the needle hole of a suture needle and sews the incision along the edge of the incised surgical site, or when the incision is sutured using the medical stapler, the suture is formed in a certain pattern. It is difficult to seal the tissue accurately and quickly, and the operation time is long.

Therefore, the problem of how to accurately and quickly suture tissue in a certain pattern has become an important technical factor for surgeons.

Korean Utility Model Publication No. 20-0410471 relates to a skin stapler for surgery. When the staple is pressed and extruded through a passage formed by the copper iron piece guide to correspond to the shape of the pressing part, the check protrusion formed at the rear end of the staple blocking part protrudes upward toward the rear side of the upper movable iron piece guide. By doing so, the staple is smoothly extruded without getting caught in the check protrusion.

However, although the above No. 20-0410471 is provided to prevent failure in advance by enabling smooth ejection of the stapler, it is difficult to apply to a narrow surgical area because the suturing method of the device is performed by up and down motion, and is used only once As a disposable suture method that is removed and removed, it is not economical, the suture procedure cannot be performed quickly and easily, and the suture cannot be sutured to the skin in a uniform pattern.

Therefore, it can be miniaturized to enable suturing of a narrow surgical site, and it is economical because it can be reused by disinfecting several times rather than disposable, and it can be simply sutured using one surgical suture, and the incised body tissue can be There is a need for the development of a medical suturer that can quickly suture, reduce wound healing time as the sutures are sutured in a uniform pattern, and increase the efficiency of suturing procedures as there is no need to remove them with a remover after suturing. It is becoming.

By being configured to perform the suture function while suturing, it is possible to perform surgery on a narrow area by shortening the movement path of the needle during suturing and to realize miniaturization of the device.

In addition, it is configured to be reused by disinfecting several times, rather than a disposable surgical tool that is used once and discarded, and thus has an economical effect.

In addition, unlike conventional surgical tools that require suturing tools from above and below using two surgical sutures, it is configured to be simply sutured using one surgical suture, enabling simple and miniaturized surgery.

In addition, the suture unit of the support unit includes a loop member, and the loop member is pulled by a needle to grip the loop of the suture inserted into the tissue to form a stitch, thereby preventing unsafe suturing or bursting after suturing. .

In addition, since the suture is sutured in a uniform pattern, it is possible to shorten the wound healing time, and there is an effect of increasing the efficiency of the suturing procedure because a process of removing the wound with a remover is not required after suturing.
