UA122389U - DEVICES FOR REMOTE OBLITERATION OF TUBLE STRUCTURES OF HUMAN - Google Patents

Abstract

The device for remote obliteration of tubular structures of a person contains two blades, between which is placed the dielectric. The working element is made in the form of a small bean, which is made of an insulating, fast-pouring mixture, on which are fixed 2 copper petals at a distance of 2 mm from each other, which provides between them an electric arc when the current is connected. Generally, beans with 2 copper petals attached to it 2 mm apart look like a small bipolar olive, each copper petal is connected with electrical cables up to 1 meter long, the proximal ends of which are drawn through an insulating plastic handle to a high frequency generator a high frequency electric current cable, the handle to which the proximal end of the cable is connected, is required to control the cable when a small bipolar olive is introduced into the lumen of a varicose vessel.

Description

The utility model belongs to medical equipment, namely to medical electrosurgical instruments, and can be used in performing surgical interventions on humans and animals for obliteration and simultaneous coagulation of biological tissues and blood vessels.

A well-known electrosurgical bipolar scalpel consisting of two blades between which a dielectric is placed. The blades of the blade are reliably connected by 1 or 2 retaining rivets made of an insulating, quick-setting mixture, which ensures a reliable fastening of the structure. The blade has a rectilinear shape and at the distal end it is curved at an angle of 60 degrees, which allows it to be manipulated on the periosteum without the use of rough tools such as a reamer.

The bipolar electrosurgical scalpel works in the following way.

The high-frequency electric current from the high-frequency generator is fed through the high-frequency current delivery cable to the high-frequency electric current input contacts, which are structurally located at the proximal end of the handle. These contacts are independently connected to metal electrodes placed on both sides of the dielectric.

The basis of a useful model is the task that the result of the introduction of such a tool should be the absence of burns of soft tissues and the negative impact of electric current on the body, the reduction of the time of the operation, the provision of visual control over the site of tissue dissection, the possibility of dissection and dilution, sufficient periosteum, which covers the bones of the upper and lower limbs of a person.

The task is solved by the fact that in the known design, which consists of two blades between which a dielectric is placed, according to a useful model, the blades of the blade are reliably connected by 1 or 2 retaining rivets from an insulating quick-setting mixture, which ensures a reliable connection structures.

The disadvantage of this device is that with the help of two bipolar blades between which a dielectric is placed, in which the blade petals are reliably connected by 1 or 2 retaining rivets from an insulating quick-setting mixture, which ensures a reliable connection of the structure, it is only possible to separate the fabrics with simultaneous hemostasis of blood vessels.

But it is impossible to obliterate a single vessel with its varicose expansion by means of intravascular influence.

To solve the task of obliterating a varicose vein, the working element is made in the form of a small bean, which is made of an insulating, quick-setting mixture, on which 2 copper petals are fixed at a distance of 2 mm from each other, which ensures the closing of an electric arc between them when a current is connected. in general, a bean with 2 copper petals attached to it has the appearance of a small bipolar olive.

Electrical cables up to 1 meter long are connected to each copper petal, the proximal ends of which are routed through an insulating plastic handle to a high-frequency generator to supply high-frequency electrical current through the cable. The handle to which the proximal end of the cable is connected is needed to control the cable when introducing a small bipolar olive into the lumen of a varicose vessel.

The drawing explains the essence of a useful model.

In Fig. 1 - small bipolar olive; 2 - electric cable; C - a handle for controlling the cable during the introduction of a small bipolar olive into the lumen of a varicose vessel.

The proposed device works as follows:

At the location of the varicose veins, dissection of soft tissues over a length of 1.5-2 cm is carried out using a scalpel, the vein is isolated from the surrounding tissues, and with the help of a blunt hook the vein is pulled into the wound by 2 cm. Using a scalpel, the wall of the selected vein is an incision up to 1-1.5 cm, through which bipolar oil with a cable is introduced into the lumen of the vein, then it is gradually pushed antegrade for the entire length of the cable, which is up to 1 meter. After the introduction of bipolar oil with a cable, a high-frequency electric current is turned on, which is 66 kHz from the generator and the cable together with the bipolar oil is gradually drawn retrograde in the reverse direction, at a speed of 3-5 mm per 1 second. As a result, the current "circulates" the petals of electrodes on bipolar oil through soft tissues, causing heating and obliteration of the lumen of the varicose vessel. Moving the bipolar oil with the cable in the retrograde direction at a speed of 3-5 mm in 1 second makes it possible to achieve bloodless obliteration of the varicose vessel along the entire length of the cable, namely over a length of 1 meter.

The achieved technical result facilitates the work of the surgeon, shortens the operation time by 35-45 minutes, provides visual control over the process of bloodless obliteration of the varicose vessel along the entire length of the cable, with limited access to the varicose vessel.

When using the proposed device for bloodless obliteration of varicose veins, the duration of wound healing became 1.5 times shorter, which is ensured by bloodless low-temperature obliteration of varicose veins, and a reduction in trauma to the patient during surgery due to the reduction of access to varicose veins.

The proposed device was successfully tested in the department of vascular surgery

of the Central Oleksandriv Hospital in Kyiv for 20 patients during surgical interventions for varicose veins. The obtained positive results make it possible to recommend it for wide implementation in practical medicine.
