RU99955U1 - DEVICE FOR Suturing Parenchymal Organs - Google Patents

Abstract

 A device for suturing parenchymal organs, consisting of a shaft and an eyelet, characterized in that the eyelet is located in the front quarter of the device, there are recesses on the sides of the eyelet, and on the one hand it reaches the end of the shaft, on the other hand it takes 3/4 of its length , the handle is equipped with a spring.

Description

The utility model relates to medical equipment, in particular to medical instruments intended for applying hemostatic sutures to parenchymal organs.

Known devices for suturing parenchymal organs: a needle for suturing wounds of the liver with dermal thread (Tsybyrne, Bargan M.A., (Surgery, 1989, No. 10, p. 124)), a surgical needle EPO (EP) - Australia, Munich p. 34 . 14, 1987. Isob. countries of the world), Aslanyan’s needle (19 ..), the device of Tikhomirova VD, Orlova MN, (A.S. No. 1438724), a medical needle in the form of a cannula (USA - Opened. Inventory of the world, 1989 , No. 5, issue 14., p. 100), a needle for suturing (Japan - Invented countries of the world, issue, 14, 1987, No. 21, page 87) and a surgical needle (Invented countries of the world. , 14, 1987, No. 20, p. 10, Ivanov S.V., Drimalovsky M.Ya.) and others are technically complex, traumatize the surrounding parenchyma tissue, do not provide reliable hemostasis, cause excessive trauma and gross morphological changes after surgery. As a prototype, we have chosen a needle for suturing the liver (Popov S.A. A.S. No. 1000024, Cl. A61B 17/06, 1983. Bull. No. 6. 02.15.02.87.), Consisting of hollow elements, element with a point, an element with an eye, interconnected by an elastic rod passing through the elements and provided with holes. All elements contact each other along mating surfaces.

It has the following disadvantages: the technical complexity of the device (consists of many hollow elements), the instability of the rod (the deflection of each element to the side by an angle of 90 degrees), injures the surrounding tissue and the need for constant washing of the needle cavity. The purpose of the proposed as a useful model of the device is to simplify the design of the device for suturing during operations on parenchymal organs.

Utility Model Description

The proposed utility model is illustrated in Figure 1. (pos. a, b), where 1 (pos. a) is the tip, 2 (pos. a) is the eyelet, 3 (pos. a) is the recess, 4 (pos. a) is the rod, 5 (pos. a) ) - spring and 6 (pos. a) - handle.

The device consists of a rod with a point on one end and a spring with a handle on the other. An eye is located in the front quarter of the rod, on the sides of which there are recesses. On the one hand, the recess reaches the end of the rod, on the other hand takes 3/4 of its length. The device works as follows: by pressing on the handle, the device with the eye advances and punctures or injects the organ parenchyma (pos. A), the pressure of the handle allows you to adjust the depth of injection into the organ parenchyma and releasing the handle, the device returns (pos. B), performs puncture, i.e. smoothly inject and poke. Moreover, the side where the recess reaches the end of the rod should be facing toward the seam.

An example of a practical application of the device:

Mongrel dog, male, age 2.3 years, weight - 15 kg. "Tuzik". Upper median laparotomy, spleen was isolated into the surgical wound. After modeling the gap, the injured organ site was resected. When suturing used this device. Reliable hemostasis and layered sutures on the wound.

Example. Dog "Watchdog" - female, 3.5 years old, weight - 18 kg.

The abdominal cavity was opened with a mid-median incision along the white line of the abdomen. The liver was isolated in the surgical wound. Previously created a liver injury in the anterior regions. An atypical resection of the injured area of the liver was performed. After wrapping the line of the alleged resection with plastic material, the liver parenchyma was stitched using this device. Hemostasis and layered sutures on the wound.

This device was used to apply hemostatic sutures during atypical resections of the spleen (30) and liver in 16 cases with good results.

Features distinguishing from the prototype:

1. the proposed utility model consists of a point, an eye, a rod with recesses and a handle with a spring, which simplifies the work of the surgeon, reduces the operation time, and the prototype has hollow elements interconnected by an elastic traction and provided with holes.

2. in the proposed utility model, the eye is in the front quarter of the device, which eliminates unnecessary injury: it is enough to hold the eye with the thread on the other side of the organ, and in the prototype the eye is on the back, which requires the entire device to pass through the thickness of the organ to the other side.

3. in the proposed utility model there are recesses in the shaft behind the ear on both sides: on the one hand, it takes 3/4 of the length of the device, and on the other hand, the recess reaches the end (that the threads lie there and eliminates unnecessary parenchyma injury), and in the prototype this symptom is absent.

4. in the proposed utility model there is a handle with a spring, which simplifies the work of the surgeon, reduces the time of the operation, allows you to adjust the depth of injection using pressure on the handle, but this sign is absent in the prototype.

A positive effect of using the developed device is to reduce the morbidity during operations on parenchymatous organs, allows you to adjust the injection and puncture, eliminating unnecessary trauma to the surrounding part of the parenchyma and there is no need to refill the needle every time, simplifies the work of the surgeon and reduces the operation time.
