The phlebextractor consists of a metal rod, three notches are made at the proximal end of the metal rod, located at a distance of 2.5 cm at the end of the metal rod at an angle of 30 °. A simple, low-traumatic device for the treatment of varicose veins of the lower extremities has been created, which makes it easier to perform interventions in emergency and planned vein surgery.

Description

The utility model relates to medicine, namely to vascular surgery, and can be used in the surgical treatment of varicose veins.

In developed countries, the frequency of varicose veins is 25-33% among women and 10-20% among men. In Russia alone, more than 38 million people officially suffering from various forms of varicose veins are officially registered, of which 15% have trophic disorders. The number of people with vein diseases annually increases by 2.5% [http: travma-net.ru> Articles.aspx ...].

In this regard, the improvement of devices used to treat varicose veins is relevant.

For venectomy, several types of phlebextractors have been proposed. In 1908, Babcock proposed removing a vein by inserting a probe with a cutting olive at the end.

There is a veneractor in the form of a wire [Patent RU No. 2260450 of January 30, 2004). With severe varicose veins, the dilated vein slides from the device.

A known design of a Nabatoff phlebractor, consisting of a flexible metal cable with a thread at the end [Aesculap Catalog Instilments for Cardiovascular and Thoracic Surgery. Brochure C No. 055311, p.132] and is used to remove trunks of saphenous varicose veins. The device is highly traumatic. It is technically difficult to insert a Nabatoff phlebextractor into the trunk of a varicose vein due to the flexibility of the instrument. When removing the end of the phlebextractor to the surface, an additional skin incision is required in the projection of the supposed localization of the olive. After that, the surgeon searches and picks up the venous trunk with a phlebological hook deep in the subcutaneous fat, removes it from the wound, dissects the front wall of the vein and displays the end of the phlebextractor with olive.

Known phlebextractor with a thickening at the end to straighten varicose-transformed sections and remove insolvent valves [Patent RU 2554379 C1 of 06.27.2015]. The device has limited use, mainly used in endovascular laser coagulation.

As a prototype, we chose a phlebextractor made in the form of a rod with a through hole. The perforating end of the rod is bent at an angle of 45 ° [Patent RU 89945 U1 of 12.27.2009]. When using this device, the tissues surrounding the venous steol are often significantly injured.

The task in the design of this device is to create a phlebextractor for conducting less traumatic removal of trunks of saphenous veins and varicose transformed its tributaries.

The technical result of the proposed device is implemented by performing three notches at the proximal end of the metal rod, providing increased reliability of fixation of the vein trunk with the metal core of the phlebextractor, which reduces the risk of venous trunk breakage during the operation.

The technical result of the proposed utility model is achieved by the fact that according to the technical solution, the device consists of a metal rod, three notches are made at the proximal end of the metal rod located at a distance of 2.5 cm at the end of the metal rod at an angle of 30 °.

The proposed utility model is illustrated by graphic material. The figure 1 presents a schematic diagram of a phlebextractor, where 1 is a metal rod, 2 is three notches at the end of the metal rod located at an angle of 30 °, 3 is the distal end of the metal rod.

The proposed device is used as follows.

Ligation and intersection of the safeno-femoral anastomosis is carried out through an incision 1.5-2 cm long in the inguinal region along the fold. Bandaging the large saphenous vein in the medial ankle. A retrograde phlebextractor is inserted into the lumen of the proximal end of the intersected saphenous vein, which provides contact with the vein on the surface of the three notches of the phlebextractor. The vein wall is fixed with a nylon thread on the surface of three notches of the metal core of the phlebextractor. After that, venectomy is performed by traction of the phlebextractor.

An example of practical use.

Patient A., 42 years old. Diagnosis: Chronic disease of the veins of the left lower limb C2,3S, Ep, As, Pr; 03/13/2014; LI. CVI II degree. Operation 03/14/14, Crossectomy. Removal of the BPV trunk on the left throughout under spinal anesthesia. After processing the surgical field, linear access was made on the inguinal fold to the safeno-femoral anastomis 1.5 cm long on the left. A large saphenous vein was ligated at the medial edge of the ankle. A retrograde phlebextractor is inserted into the lumen of the proximal end of the dissected large saphenous vein. The vein was fixed with kapron thread on three notches of the metal core of the phlebextractor. After this, traction was performed venectomy BPV throughout.

Separate interrupted sutures, an aseptic dressing and compression hosiery of compression class II were applied to the wounds.

The postoperative period was uneventful. The patient was discharged in satisfactory condition on the 3rd day after surgery.

A clinical example indicates the possibility of using the proposed device for the surgical treatment of varicose veins.

A simple, low-traumatic device for the treatment of varicose veins of the lower extremities has been created, which makes it easier to perform interventions in emergency and planned vein surgery. This device reduces the risk of venous trunk rupture during stripping by increasing the reliability of fixing the vein trunk at the proximal end of the metal core of the phlebextractor.

The proposed utility model was introduced on the basis of the “NUZ Separate Railway Hospital at Tyumen Station” and used in surgical treatment of veins of the lower extremities. 12 operations were performed.
