Description

ULTRASONOGRAPH SENSOR LOCKER

Ultrasonography (US) probe retainer refers to a medical technique that is intended to be used in ultrasound imaging to manipulate the US probe, hold it in the position required by the physician, and release the physician's hand for manipulation.

Ultrasound imaging is a harmless and painless procedure for the diagnosis of organs and tissues, which uses high-frequency sound - ultrasound - to obtain images. It has been in use for at least 50 years, but only now, thanks to the latest modern technology, is it being widely adopted in medical practice around the world.

Various versions of the US (depending on the manufacturer) have been developed, but what they all have in common is that the diagnostic is done with a US probe (varying in size and shape depending on the manufacturer) that is connected to the US via a connecting cable.

The physician performs manipulation of the US probe, such as precise nerve localization with visual control on the US monitor screen, and once the desired nerve or nerve plexus is localized, the US probe must be precisely locked to release the physician's hands, e.g. the US probe must be fixed, the needle must be held, and the medication inserted, and it is important that these manipulations can be performed by a physician without the need for additional staff. [1; 2; 3; ]

Such probe fixation devices are not provided in the US, but are required by the practitioner, as in this case the required manipulation may be performed by the physician alone without the assistance of additional personnel.

There is a known device, a prototype [4], which solves this problem, but in this case the probe holder is designed to encircle the US probe almost all along its two sides and the US probe is secured in the holder with two screws (top and bottom), which generally increases the size of the US probe by at least 1/3, which makes it difficult for a physician to manipulate the probe and insertion into the probe holder requires some time to tighten the US probe holder screws, which may cause the disposable sterile cover to be attached behind the screws and burst.

The base mount is designed as a spherical hammer, which is difficult to manufacture because it requires very high precision and must be loosened and rotated every time the ball is secured.

The flexible armature is made up of a single section that holds the US probe, the US probe holder and its own weight, and is simultaneously designed to manipulate the US probe, which limits the length of the flexible armature. but this, in turn, limits the finer manipulation of what is needed for accurate nerve localization with the US probe.

Flexible fittings are made up of separate, interconnected, movable and complex construction segments, which make it very difficult to manufacture them and, consequently, for economic reasons to be widely used in medical practice.

The object of the invention is to provide a universal mobile latch for manipulating the US probe and positioning it in a position necessary for its fixation, while being simple enough to be widely used and practiced by physicians; to simplify the construction of the base fastener to facilitate its manufacture and that once fixed to the support it should not be reattached and to change its design to facilitate the manufacture of the flexible reinforcement.

The set purpose is achieved by the fact that the base mounting (1) is in the form of a screw-type, the flexible reinforcement consists of two parts: the main part (2) and the additional part (3); The US probe holder (4) consists of a US probe support plate (6) with four circular clamps (7) unfolded and a US probe holder (4) welding screw (6) welded under the US probe (8) support plate (6) 5).

The length ratio of the base part (2) of the flexible armature to the additional part (3) of the flexible armature is in the range (8-10): (1-2), but the ratio of the outer diameter is in the range (0.15-0.2) :( 0,1 - 0.15) where 1 and 10 cm.

The shape and dimensions of the support surface plate (6) and the circular clamps (7) of the US probe holder (4) depend on the shape of the US probe.

The base of the flexible armature (2) holds the weight of the US probe holder (4), the US probe (8) and its base weight, while the additional part (3) of the flexible armature provides fine manipulation of the US probe (8).

The base part (2) and the additional part (3) of the flexible reinforcement are made of a homogeneous, tensioned material, which is easy to manufacture.

The invention is illustrated by drawings wherein:

FIG. 1 shows an overview of the US probe latch;

FIG. 2 shows the probe holder for the US probe latch;

FIG. Figure 3 shows a probe holder for a US probe retainer with a US probe inserted therein.

The US probe latch comprises a screw-type base mount (1) which screws in the flexible armature body (2), which in turn screws in an additional flexible arm part (3) into which the US probe holder (4) is screwed. The screw points are secured with fixing glue. The US probe holder (4) is formed from a support surface of the US probe in the form of a plate (6), from which four circular clamps (7) are folded according to the shape and dimensions of the US probe (8); underneath the US probe (8), the mounting screw (5) of the US probe holder (4) is welded in the form of a plate (6). The US probe holder (4) is covered with a matte material to improve the locking of the US probe (8) in the holder and prevent scratching during insertion and removal. The flexible reinforcement consists of two parts: the base part (2) and the auxiliary part (3), the ratio of the length of the flexible part of the reinforcing body (2) to the additional part (3) of the flexible reinforcement is in the range (8-10): but the ratio of outer diameter is in the range (0.15 - 0.2): (0.1 - 0.15), where 1 is 10 cm. The flexible reinforcement (2, 3) is made of uniformly tensioned material. A flexible clamp (9) is attached to the flexible armature (2, 3) for attaching the US connecting cable to the US probe (8).

The US probe latch is used as follows:

The universal probe clamp (1) secures the US probe latch to the support surface in the immediate vicinity of the patient.

Insert the US probe (8) into the US probe holder (4) and secure the connecting cable with the flexible clamps (9).

Apply a disposable sterile cover to the US probe (8).

The area of the patient's skin to be examined is treated with a sterile gel.

Using the US Probe Latch Flex Fitting Body (2), the US Probe (8) guides the patient in the immediate vicinity and using the Flex Flex Attachment (3) over the skin to be examined by visual control on the US monitor until, for example, the nerve or nerve localized.

Due to the locking properties of the flexible armature (2, 3) (according to the proportions above), the probe holder (4), together with the US probe (8), maintains the desired position found and the physician can release the hand with which Perform the necessary manipulations - hold the needle and administer medication, for example, by blocking a nerve.

The US probe latch is versatile, mobile and easy to use, as well as easy to manufacture and hence widely available for use in medical practice.
