Device for compression of the creation of anastomoses

 

(57) Abstract:

Usage: in surgery for compressive creation of anastomoses. The invention consists in that the device comprises two annular element 1 United interconnected rigidly fixed internal drive from a material with the effect of the form and the annular connecting elements 1 are made oval, and the internal drive is made in the form of a rod 2, oriented along major axes of the connecting elements 1, while terminal 2 is fitted with a sealed elastic insulating cover 4 with the inner surface under the coolant 5. 3 Il.

The invention relates to medical equipment and can be applied when forming a compression anastomosis between hollow bodies.

A device for creating anastomoses by compression, made in the form of two coils of wire of a material with shape memory effect. The instrument provides a reduction in the frequency of early and late postoperative complications after creating anastomoses between hollow organs and facilitates the imposition of the anastomosis. However, the known device forms the bulk of compression nedostatki hand seam. This is a significant drawback of the device is related to the fact that the place of transition from one turn to another prevents the creation of a uniform and full compression in the device all the walls full of bodies, all over anastomoticheskih rings.

A device for compression of the creation of anastomoses, selected as a prototype consisting of two connecting elements in the form of hemispheres and host their information in the form of a spiral spring Nickel-titanium connecting these hemispheres and forming a spherical device. The device provides full compression anastomosis around the perimeter formed by anastomosis. The disadvantages of the known devices are: a significant amount, size and weight of spherical designs, making it difficult to progress through the lumen of the intestine and does not allow to pass to the device after exclusion through Bauhinia the ileocecal valve angle. This excludes its application to the small intestine and the stomach. Another significant drawback is that the spiral spring made of titanium nickelide despite its great length and volume in a spiral, having a high conductivity metal, instantly reduced when in contact with body tissues that due to strict time limit. In addition, the device is complicated and consumes a large amount of material with shape memory effect. Thus, all this makes it difficult, and in some cases eliminates the use of this device.

Object of the invention is a device to perform a full compression anastomosis in the gastrointestinal intestinal tract above bauhinias ileocecal valve angle by reducing the volume, size and weight, being able to control the speed of operation of the device in the direction of the slow warming of the node information (internal drive) after contact with body tissues and, consequently, increasing the time limit for installation design and simplify the design of the device and saving material with shape memory effect.

The problem is solved by the fact that the device for compression of the creation of anastomoses, containing two annular connecting element connected between a fixed internal drive from a material with shape memory effect, the annular connecting elements are made oval, and the internal drive is made in the form of a bent rod with orientation along major axes connect ladusaw liquid. This bananoobraznye advanced case with liquid serves as a limiter when submerged edges stitched authorities, necessary for the preservation of primary patency of the anastomosis, and slows down the heating of the internal drive from a material with shape memory effect.

In Fig.1 shows a device for compression of the creation of anastomoses in the initial position, the front section of the General form of Fig.2 introduction device through which the ends of the stitching hollow organs, cut the General form of Fig. stage 3 of the functioning of the device after the installation is complete designs in a lumen formed by anastomosis of the cut.

Device for compromising create anastomoses (see Fig.1) contains two oval ring 1 made of titanium and the internal drive of titanium nickelide brand HS-10, HS-20 in the form of a bent with two knees of the rod 2, which is rigidly fixed to the two opposite points 3 oval rings 1 with orientation along the large axis. Terminal 2 is closed airtight, elastic insulating cover 4 with the inner surface under the coolant 5.

Device for compression of creating anastomoses works as follows (see Fig.2). In the cavity of termoizolyaciya. Then throw oval ring 1 from each other by 1-1,5 cm is Ready for operation, the device is introduced into both ends of the resected intestine 6 and, dipping the edges of the walls of the latter in the device to bananoobraznye extended case 4, tighten with a slight pre-tension imposed purse string sutures are not tied to the possibility of their removal after the start of compression of the walls of the intestine. The installation phase is completed by the suction of the coolant 5 through a needle from the cavity of the cover 4, which leads to a rapid closure of the oval rings 1 and compression pressed the edges of the ulcer 6 (see Fig.3). This is a result of the heating rod 2 Nickel-titanium to body temperature and, as a consequence, recovery of the original shape and sverkhuprugost rod 2. Rigid internal fixation of the drive-rod 2 in two opposite points of construction along major axes of the rings 1 leads to uniform compression throughout anastomoticheskih rings with reliable physical and biological integrity of the formed fistula. After complete necrosis locked areas within 7-9 days the device easily passes through Bauhinia the ileocecal valve angle intestine 6 due to the small volume, size and weight, as well as oval the STS and at the same time when balasooriya it limits the depth of the edges of the ulcer 6 to ensure sufficient primary patency of the anastomosis. The average size of the structure and its specific power compression in working condition in accordance with generally accepted values in surgery compression anastomoses.

Thus, the optimal ratio and placement of structural elements of the device leads to the simplification of the structure, making it mobile, managed the installation organs, easier izgotovliaemye and at the same time vastly a material with shape memory effect. The manufacture of devices of different size makes it versatile in use.

DEVICE FOR COMPRESSION of the CREATION of ANASTOMOSES, containing two annular connecting element connected between a fixed internal drive from a material with shape memory effect, wherein its annular connecting elements are made oval, and the internal drive is made in the form of a rod, oriented along major axes of the connecting elements, in this case the rod fitted with a sealed elastic insulating cover with the inner surface under the coolant.
