Abstract

Field of application: the invention relates to medicine, namely to dentistry, and can be used to remove salivary stones from the inflow of the submandibular gland; The essence of the invention. Shade: The dental instrument contains a handle with a working part. What is new in the tool is that the working part is made in the form of an S-shaped cross-section plate, with the upper working end bent at an obtuse angle with respect to the plane of the plate towards the tongue, and the lower working end of the plates M is rigidly attached at an angle to the plane plate the needle is bent to indicate the curvature of the plate. 2 ill.

Description

The invention relates to medical equipment, namely to dentistry, and can be used to remove salivary stones from the excretory duct of the submandibular salivary gland.

A common set of tools for removing salivary stones from the excretory duct of the submandibular salivary gland is known: scalpel, needle holder with needle, curettage spoon, tweezers, spatula.

A surgical needle fixed in the needle holder is brought under the stone across its longitudinal axis. The needle holder lifts the stone up. The fabrics covering the stone turn pale and the stone is clearly visible. The mucous membrane, underlying tissues and duct wall are dissected with a scalpel. The stone is removed.

The disadvantage of this tool kit is that it is not possible to simultaneously fix the tongue and salivary stone and

securely fix the latter. In addition, the manipulation of several instruments complicates and lengthens the duration of the operation.

The prototype of the invention is a needle holder with a needle comprising a handle and a working part 1.

Salivary calculi are removed by dissecting the mucous membrane, underlying tissues and duct wall directly above the calculus with a scalpel. A silk ligature is drawn under the duct behind the stone; the tongue is put back in the opposite direction with a spatula.

A disadvantage of the known tool is that. that by pressing with a scalpel it is possible to move the stone inward along the duct. In addition, 2 assistants are needed: one to move the tongue away with a spatula and to tighten the ligature, the other to help the surgeon when working in the rank.

The aim of the invention is to ensure the simultaneous fixation of salivary stone and tongue.

The goal is achieved in that in a dental tool containing a handle with a working part, the working part is made in the form of a plate of S-shaped cross-section with different radii of curvature of its parts, while the plate is equipped with a curved needle fixed by a sub-angle of 70-90 ° to the axis of the tool, and the free end of the needle is congruent to the surface of that part of the plate that has a larger radius of curvature.

Fig. 1 shows a dental instrument, general view; figure 2 - S-shaped cross section of the working part from the side of the handle.

The tool contains a handle 1, the working part 2 with a curved needle 3 fixed at an angle of 70-90 ° to the axis of the tool.

The tool has two versions: for the right and left sides of the oral cavity and is made of stainless steel (ST-9X-18).

When using a laser scalpel, in order to avoid reflection of the laser beam and injuring the eyes of the doctor, the surface of the plate where the needle is bent is sandblasted.

The salivary stone removal operation is as follows. An S-shaped working part with an attached needle is inserted into the corresponding half of the patient's oral cavity. The sharp end of the needle is drawn by a PBB stone, and the outer surface faces toward the box surface of the tongue. By moving the needle under the stone, the instrument is given a rotational movement and the outer surface, facing the tongue, passes into the maxillary groove, moving the tongue. When the sharp end of the needle enters the oral cavity, the stone appears to be a fixed needle and is pressed against the edge of the internal curvature of the working part. The tongue is also fixed by the working part, and the back of the tongue is directly squeezed by the external curvature of the plate. At the same time, a fixed salivary stone is closely pressed against the oral mucosa, stretching it, underlying tissues and the wall of the excretory duct. When dissecting thinned and stretched tissues over the stone, the stone immediately leaves the wound under pressure of a needle and is removed from the oral cavity with ordinary tweezers.

Examples of specific performance are given in the form of extracts from the medical history:

PRI me R 1. Alekseeva I.V., 19 years old, medical history No. 5923 was admitted to the maxillofacial department of the regional hospital named after N.A. Semashko on March 29, 89 about salivary-stone disease, stone excretory duct of the submandibular salivary

glands on the left. Sick for 5 years. Examination reveals increased submandibular salivary gland. In the excretory duct, a calculus of 0.5 x 1.5 cm is palpated. From the mouth of the duct, saliva does not

0 is highlighted. On the roentgenogram of the bottom of the oral cavity, at the level of the premolars on the left, the calculus calculus is 0.5 x 1.5 cm.,

.Operating: removal of stones from the excretory duct using a dental instrument. Torus anesthesia. The calculus is palpated. A dental instrument is inserted into the maxillofacial groove. The needle is held under the stone.

0 The working part is deployed, pushed back and fixed tongue. At the same time, the stone is pressed with a needle to the mucosa of the bottom of the oral cavity and to the lower working end of the plate. The mucosa, underlying tissues, and the duct wall are cut with a scalpel. Hemostasis. Stone extraction The wound was left open. In the first three days, saliva was released into the wound, then the edges of the wound were sticking together, the epithelialization of the wound occurred on the 9th day. Function

0 duct and salivary gland is restored, the gland is the same size. . 1- Observation of the patient for 6 months showed the absence of inflammatory phenomena in the duct and gland. There is a postoperative scar in the region of the glenoid groove. Transparent saliva, normal sized iron, is released from the excretory duct. The duct function is not impaired.

Example 2. A. Sinitsin, 32 years old, case history No. 9070, was admitted to the maxillofacial department of the Regional Hospital named after N. A. Semashko on April 6, 90, due to salivary stone disease, stone in the excretory duct of the submandibular salivary gland on the left. Disease duration 7 months. The patient notes a swelling in the submandibular region associated with eating. On examination: salivary gland increased in size, soft consistency. Palpation in the distal maxillary groove palpates the calculus 0.5 x 1.0 cm,% of the excretory duct is cloudy

5 saliva.,

Surgery: stone removal using a dental instrument and a laser scalpel,

Torusal anesthesia. Palpation is determined stone. Dental

the instrument is inserted into the maxillofacial groove. The needle is held under the stone, the working part unfolds, pushes and fixes the tongue, while the stone is pressed by the needle to the mucosa of the bottom of the oral cavity and to the lower working end of the instrument. The fabrics above the stone are stretched and thinned. A laser mucosa dissected the oral mucosa, underlying tissue and duct wall. The wound is dry, that is, the stone lies in the wound, removing it. A wound under the surface film of coagulation necrosis. Par on left open. The next day, the edges of the wound stuck together; on the 7th day, epithelization of the wound began. The duct and gland functions have recovered.
