Description

SET OF TOOLS FOR ASPIRATION BIOPSY.

The utility model relates to surgical instruments, in particular, used for aspiration biopsy and may find application in the surgical departments of medical institutions.

Currently, a common set of instruments for performing aspiration biopsy procedures is known 1. This kit contains: syringes, biopsy needle, stylet, puncher (scalpel), gauze napkins (bandages), paper towel (cellular blanket).

This tool kit is housed in serial packaging and is disposable.

The disadvantage of the described set of tools is the insufficient diagnostic efficiency of the method due to the relatively small amount of material taken and insufficient ultrasound visualization of the position of the biopsy needle.

The purpose of this useful modeling is to simplify the procedure and increase the diagnostic effectiveness of the aspiration biopsy method.

This goal is achieved by the fact that in a known set of instruments for aspiration biopsy containing a biopsy needle, stylet, syringes, including with a locking stopper, an ampoule with

An anesthetic solution, a perforator, glass slides, gauze wipes and a paper diaper were introduced an additional extension adapter placed between the needle and the syringe, a tube with physiological saline NaCI, a bactericidal patch.

At the same time, the presence of an extension adapter made in the form of a flexible tube with connecting elements and a fixing stopper for the aspiration syringe made in the form of springs frees the hands of the operating doctor and allows you to maintain a vacuum in the needle-extension adapter-syringe system throughout the entire biopsy. The biopsy needle has a serrated cutting edge, which allows for the collection of a large volume of material. Marks on the surface of the needle, circular or spiral cuts on the stylet from the sharpening side provide reliable ultrasonic visualization of the position of the end of the needle with the stylet. A tube with physiological NaCI solution allows, by washing the needle, extension adapter and syringe after emptying, to increase the mass of the test material. Toning of glass slides facilitates cytological studies of the obtained material.

The proposed set of tools is presented in figure 1. Figure 2 is an enlarged view of a biopsy needle, Figure 3 is an enlarged view of a stylet, Figure 4 is a view of the location of a biopsy needle with a stylet when they achieve a punctured formation, Figure 5 is a view of a biopsy needle in a punctured formation, where the arrows show the direction of its movement when sampling the material.

Figure 1 shows: 1 - a biopsy needle with a stylet, 2 - an extension adapter, 3 - a syringe for aspiration with a spring stopper, 4 - a syringe for local anesthesia, 5 - a tube with physiological NaCI solution, 6 - ampoule of the drug for local anesthesia, 7 glass slides, 8 - a leather punch, 9 - a paper diaper, 10 gauze napkins, 11 - a bactericidal patch.

Figure 2 shows: 12 - gear-cutting edge, 13 - outer rows of marks, 14 - inner hole.

In Fig. 3 are shown: 15 - pointed faceted vertex, 16 circular cutting.

Figure 4 shows: 17 - biopsy needle, 18 - stylet, 19 punctured formation, 20 - skin.

Figure 5 shows: 17 - biopsy needle, 19 - punctured formation, 20 - skin, 21 - arrows of the direction of movement of the needle when sampling material.

An aspiration biopsy using the proposed set is performed as follows:

Under ultrasound or fluoroscopic control, the optimal puncture point of the formation of interest is determined.

Antiseptic treatment of the skin in the puncture zone is performed. The protective layer is removed from the sticky portion of the diaper (9) and

the operational field is wrapped. Using a syringe (4) and an anesthetic solution from an ampoule (6), local anesthesia of the skin (20) and tissues is performed along with the proposed puncture. The skin is pierced with a perforator (8). A biopsy needle with a stylet (1) is inserted through an incised skin area under ultrasound or fluoroscopic control until its tip (15) reaches the formation of interest (19) (Figure 4). The stylet is removed. An extension adapter (2) is connected to the needle. An aspiration syringe (3) is attached to the extension adapter.

By pulling the piston of the syringe until it is fixed by the stopper spring in one of the positions, the necessary vacuum is created in the system: needle - extension adapter - syringe. Constantly rotating the needle (clockwise and counterclockwise), fan puncture (20) is performed (Figure 5).

The extension adapter (2) is disconnected from the needle (1). The hole of the needle pavilion closes with a finger and the needle is removed with a quick movement. The extension adapter is reattached to the needle. After squeezing the fixing springs of the stopper of the aspiration syringe (3), the tissue column is squeezed onto the glass slides (7).

The needle is placed in a test tube with saline (5). The needle, extension adapter and syringe are flushed with saline. The tube with dialysate is sealed and, together with the slide, is sent for cytological or histological examination.

The surgical field is treated with sterile wipes (10). An aseptic sticker is applied using a bactericidal patch (11).
