RU30552U1 - Alloy thread loop lock - Google Patents

Description

Alloy thread loop lock.

The utility model relates to medicine, namely to surgery and can be used for alloying.

Ligation is widely used in medicine. The sliding node is used in surgery in situations where there is a narrow intraoperative access, as well as in endoscopic medicine. However, in most cases of using a sliding node, its loop is not fixed, which makes it difficult to throw it on an object, especially if you use threads that easily change their shape, or they are made of soft material.

As an analog, the authors offer a disposable plastic or metal pusher. It is a hollow tube with an outer diameter of 5 mm., An inner diameter equal to the thickness of the ligature, 25 cm long. One of the ends of this tube has the shape of a cone. To precisely position the ligature, the end of the pusher is brought to the right place, and then a loop is completely tied and the end of the thread is cut. (Endoscopic surgery. Volume 1, 2/3, 1995, Article 58. Publisher Media Sphere. Moscow.)

The disadvantages of the analogue include:

- The loop is free - not fixed, which makes it difficult to throw a loop on the object.

- If the loop is made of thin or twisting material, the shape of the loop changes, making it difficult to throw the loop over the object.

As a prototype, the authors propose an anoscope - ligator. It consists of a cylindrical tube with a length of 8 cm and a diameter of 24 mm., Having a side window with a diameter of 16 mm., Necessary for introducing a hemorrhoid into the device, along the edges of which there are 8 micro-holes of the same diameter, sufficient to introduce a loop rJo51o, -. ::

duplicate. A thread is introduced into these holes in the form of loops - duplicates around the entire perimeter of the window. At the base of the proctoscope, its ends are connected by the Roder node. Another fixing ligature is carried out externally through the loops of the duplicate and is tied up so that the threads of the ligating hemorrhoidal knot fall out of the microholes (Certificate for Utility Model “Anoscope-Ligator No. 22296 from 20.06.02).

The disadvantages of the prototype include:

- The anoscope - ligator has a window that is connected to the body, which limits the possibilities of ligation.

-Anoscope - the ligator has a standard size, made of hard material, has one window, which does not allow use in numerous intraoperative situations.

The authors propose a latch loop ligating thread. It consists of a polymer ring, with a cross-sectional diameter of 4 mm, an inner diameter of 2 cm, with a rectangular area 5 mm long., 6 mm wide., 4 mm thick. Over this pad, the ligature lock is gripped by the clamp. On the inner surface of the polymer ring at 3, 6, 9 and 12 "hours of the conditional dial are located slit-like slots, 2 mm deep. The loops of the ligating thread are inserted into the silk-shaped holes, and its ends are tied with a sliding knot, while its free end of the ligature is inserted into the pusher.

In the practice of a proctologist, it seems appropriate to have a set consisting of loop clamps of an alloying thread of various diameters (from 1 to 5 cm) of thickness (ring diameter from 2 to 6 mm.) And the number of silk-shaped holes (from 3 to 12).

The benefits of the utility model are as follows:

- The loop is fixed in the ligature lock, which does not allow it to change its shape.

- The ligation thread retainer is not connected to the anoscope body, which greatly expands the possibilities of ligation in endoscopic and traditional medicine.

- The latch loop of the ligation thread can have different sizes (when using the kit), which allows you to ligate objects of various sizes.

The device of the utility model is shown in Figure 1. A ligating loop loop fastener consisting of a polymer ring, with a cross-sectional diameter of 4 mm, (1) with an inner diameter of 2 cm. (2), with a rectangular area 5 mm long., 6 mm wide., 4 mm thick. (3). Over this pad, the ligature lock is gripped by the clamp. On the inner surface of the polymer ring at 3, 6, 9 and 12 "hours of the conventional dial there are slit-like openings, 2 mm deep. (4). The loops of the ligation thread (5) are inserted into the helical holes, and its ends are tied with a sliding knot (6).
