RU18907U1 - LIGATURE DEVICE - Google Patents

Abstract

A device for carrying out a ligature, including a needle with a needle holder, characterized in that the needle holder is made in the form of two pivotally connected jaws, at the end of one jaw there is a hole with a thread for screwing the needle, and at the end of the other there is a semi-oval cut for passing the needle with the ligature.

Description

Device for ligature

The utility model relates to veterinary medicine, in particular to surgical instruments.

For suturing wounds, there are various types of needle holders (Mathieu, Geghara, Troyanova) and surgical needles that are widely used in the practice of medicine and veterinary medicine (Catalog of veterinary and zootechnical instruments, apparatus, instruments and equipment. M .: Kolos, -1972).

However, due to the density of the skin in farm animals, it is difficult to use these tools, since the needles in the needle holders are not always tightly fixed and often break.

It is also known a device for suturing the wound surface in animals consisting of an awl-shaped needle and a needle holder made in the form of a handle (A. S. Kashin. Ligature needle for suturing. Veterinary medicine, 1990. -C. 55-56). However, when the skin is punctured with such a needle, the wound is stretched, which often leads to additional tissue injury. To eliminate these drawbacks, we offer a device made in the form of a needle with a needle holder. New is that the needle holder is made in the form of two pivotally connected jaws, at the end of one of the jaws there is a hole with a thread for screwing the needle, and at the end of the other, a semi-oval cut is made to hold the needle with the ligature.

When the needle is screwed into the hole of one of the jaws, it is tightly fixed and when piercing the skin freely penetrates through it. Due to the sufficient area of the “jaw legs,

compression, tissue injury and trauma of the wound does not occur. The cutout in the working part of the needle during surgery allows you to quickly insert suture material into the needle and remove it back. A semi-oval incision in the upper jaw serves to pass the needle with the ligature.

The device consists of two branches (see figure), top 1 and bottom 2, which are pivotally interconnected. Each jaw consists of a handle 3 and a tab 4. In the lower jaw 2 there is an opening with a thread 5 for screwing the needle 7, and in the upper one there is a semi-oval cut 6 for holding the needle 7 with the ligature. Needle 7 has a slightly curved shape, in its pointed working end there is a notch 8 for introducing suture material. At the opposite end of the needle 7 there is a thread that allows you to tightly fix the needle 7 in the jaw 2. Between the handles of the jaws there is a leaf spring 9 with which the handles are kept open, which facilitates the work with the device. For convenience in operation, the device is equipped with a set of needles of different sizes.

Before using the device, it is preliminarily sterilized by boiling, then the needle is filled with suture material, branches are diluted as much as possible and tissue is dug from the inside of the wound. To facilitate the passage of the needle through the skin, the jaws are connected by pressing the handles of the device. In this case, the ligature needle passes through the skin and the hole in the opposite jaw. Then the ligature is removed from the needle and a new puncture of the tissues is made, thus the required number of stitches is produced and the wound is sutured.

When using the device, productivity is significantly increased and the work of veterinarians during surgical adeoations is facilitated.
