UA118516U - INSTRUMENT FOR MINIFLEBECTOMY IN VARIQUE DISEASE - Google Patents

Abstract

The tool for carrying out a miniflebectomy for varicose veins contains a handle with a hook at one end and a curved blade at the other end. The hook ends with an arcuate surface.

Description

The useful model belongs to medicine, namely to vascular surgery, and can be used in the cosmetic treatment of varicose veins of the lower extremities.

Varicose veins is a vascular pathology that is manifested by the expansion of veins on the lower extremities and occurs as a result of the weakness of the vascular wall. This pathology is in Ukraine and other countries

Europe is the most common pathology, which affects 20-30 95 of the population. Over the past 30 years, the latest methods of surgical treatment have been actively introduced into daily medical practice, including minimally invasive, economical, minimally traumatic treatment technologies, which have a number of advantages compared to classical veneectomy: minimal trauma, a short period of hospitalization and rehabilitation, and a high cosmetic effect. One of the highly effective methods of treating varicose veins certified in Ukraine is radiofrequency ablation and endovasal laser coagulation of veins and, as an addition, minirlebectomy of additional veins of the large and small saphenous vein system, which is performed from 1.5-2.0 mm punctures on the thigh and lower legs.

To perform miniphlebectomy since the 60s, specific tools (hooks, spatulas) have been introduced into clinical practice, with the help of which the tributaries of the main trunks of subcutaneous veins are removed subcutaneously, by the tunneling method, in varicose disease of the lower extremities.

The proposed approach is minimally traumatic and gives a good cosmetic effect, which is especially important for young and middle-aged patients.

The closest to the proposed useful model is a tool for miniphlebectomy in varicose veins - a double-sided MyPeg minirlebextractor with a hook at one end of the tool handle and a curved blade at the opposite end | (SNhopis Mepoiv

The disadvantage of this tool is that for miniphlebectomy it is necessary to use an additional tool - a scalpel, with the sharp blade of which an incision is made on the skin for the introduction of the hook of the miniphlebextractor. To some extent, this is an additional manipulation and leads to an increase in the number of instruments and the duration of the surgical intervention.

The basis of the useful model is the task of improving and optimizing the tools for miniphlebectomy in varicose veins in order to ensure the possibility of speeding up the removal of additional branches of varicose veins.

The task is solved by the fact that the tool for performing miniphlebectomy for varicose veins, consisting of a handle with a hook at one end, and a curved blade at the other end, according to a useful model, the hook ends with a blade-like surface.

We have developed a new tool for miniphlebectomy (hereinafter referred to as a miniphlebextractor), in which the hook ends with a pointed surface for piercing (paravasally) the skin with simultaneous capture of the varicose vein and its removal through the puncture into the wound for further transection.

The proposed and improved tool performs three functions: skin puncture and vein capture with the removal of the latter into the wound from one end of the tool (two functions), and the third function is subcutaneous dissection of the severed vein using the opposite end of the tool - the blade.

Drawings explain the essence of a useful model.

In Fig. 1 shows the general view of the miniflebextractor, where 1 is a hook with a sharp surface, 2 is a handle, C is a curved blade.

In Fig. 2 - hook 2 with a sharp surface.

On Fig. C - curved shoulder blade 3.

Miniflebextractor consists of a handle 1, at one end of which there is a hook 2 with a pointed end, and at the other end of the handle there is a curved blade 3.

The instrument for miniphlebectomy is used as follows. For a patient with varicose veins, the skin is punctured with the pointed end of hook 2 (Fig. 3), holding the miniphlebextractor with handle 1. The vein is captured with the removal of the latter into the wound from one end of the instrument containing hook 2. After that, with the help of spatula C (Fig. 2), which is located at the opposite end of handle 1 of the miniphlebextractor, conduct subcutaneous dissection of the vein to the place of further puncture.

The proposed tool was tested in clinical practice on the basis of the 1st city clinical hospital named after Prince Lev, Lviv (a branch of the Department of Surgery and Endoscopy, Faculty of Postgraduate Education, Lviv National University named after Danylo Halytskyi).

In all cases of surgical intervention for varicose veins using the minirlebectomy method, local anesthesia of 0.5 95 novocaine was performed and the improved tool proposed by us was used. The wounds did not require suturing due to the absence of diastasis of the edges. An aseptic adhesive plaster on a paper base was applied to the wounds. After surgery, an elastic bandage from the base of the fingers to the inguinal fold or an elastic stocking of the II type of compression was applied to the lower limb. The first dressing was performed the next day, and the patient was discharged from the hospital on the same day.

The use of the proposed tool for the surgical treatment of patients with varicose veins showed a good result: positive clinical changes were noted, speeding up the surgical intervention by 8.6:20.05 minutes, the average bed-day was 1.5:-0.2.

A clinical example.

Patient N., 32 years old, was admitted to the surgical department on October 5, 2016 with varicose veins of the right lower limb. HVN S I a. He has been suffering from varicose veins for 7 years.

She was treated on an outpatient basis, took venotonics, wore elastic stockings, noted some relief.

During hospitalization, the patient's condition is satisfactory. Varicose veins are noted on the right lower limb in the middle third of the thigh and lower leg along the course of the large saphenous vein. Small saphenous vein is not common. Varicose veins are noted on the anterior-lateral surface of the lower leg and thigh. There are no blood clots, the skin over the veins is not changed. In general, clinical and biochemical examinations are within normal limits. X-ray of chest organs: no pathology. UAS of the lower extremities: Reflux of blood in the large subcutaneous vein on the right (h--f), there is no reflux in the small subcutaneous vein. Pulsation on the femoral and popliteal arteries is preserved on both sides, on a. dogzaiizreaiv, a. ibriaiizrovietiog - satisfactory. Consultation of a therapist and a gynecologist: practically healthy. On October 5, 2016, an endovasal laser coagulation operation of the large subcutaneous vein of the right lower limb was performed under local anesthesia. Minirlebectomy with the proposed instrument on the right thigh and lower leg. The duration of the operation is 48 minutes. On October 6, 2016, a dressing was performed, minor hematomas in the areas of punctures on the thigh and lower legs, the wounds are calm. T - 36.7 76.
