Description

[0001] The utility model relates to surgical dentistry and maxillofacial surgery and can be used to obtain bone tissue in the area of ​​the external oblique line of the lower jaw, compact osteotomy of the jaws, access to impacted teeth during their removal, and the formation of access to the maxillary sinus.

[0002] To assess the novelty of the claimed solution, we will consider a number of known technical means of a similar purpose, characterized by a set of features similar to the claimed device.

[0003] A known oral protective device, according to USSR Patent Application No. 1461439, IPC A61C 1 / 16, 1989, consists of a tissue protection unit with a fixed lower plate and a movable upper plate connected by a hinge. The device eliminates the possibility of injury to the mucous membrane of the tongue and cheek during dental procedures.

[0004] The disadvantage of this protective device is its complex design and additional manipulations required to install the device in the oral cavity.

[0005] The Micro-Saw (Frios) product is known (https; / / www.youtube.com / watch?v=4DRymxqgr-Ng&app=desktop), consisting of a metal base to which two ring elements for placing the tip of a dental instrument and a half ring for placing a cutter are attached in sequence.

[0006] The disadvantage of this device is its limited use only for a certain type of tip produced by Frios, which is not available on the Russian dental market.

[0007] A metal protector is known, which is used with an angled tip (Saw Cover, from MrCurrete (Korea) (mrcurette.ru>articles / 13-tip.html), consisting of a metal base, to which a small and large removable seating ring with a slot for an irrigation nozzle for placing the tip of a dental instrument and a half ring for placing a cutter are attached in sequence.

[0008] The general disadvantage of the above-mentioned protective devices is the impossibility of purchasing, bulkiness, complexity of design, and limited use only with a certain type of tips, not available for sale in the Russian Federation.

[0009] A known protective device made of plastic for a surgical dental handpiece with a cutter according to IM No. 209974, containing a housing of two longitudinal strips, conically passing into a neck made in the form of a semi-cylinder with an end semi-ring located at its end with a stop platform for placing a cutter in it, on which an opening is made in the center of its surface for inserting an irrigation tube, and on the outer cylindrical surface of the neck a groove is made for laying the irrigation tube, wherein the longitudinal strips are spaced apart from each other to form an opening, and in the opposite part of the housing on the longitudinal strips large and small fixing rings are located coaxially from each other for fastening a dental handpiece in them, and on the small fixing ring an opening is made according to the size of the opening between the longitudinal strips,and a slot is made on the large fixing ring with the possibility of increasing the diameter of the large fixing ring when it is placed on the dental handpiece.

[0010] This technical solution, as the closest to the declared one in terms of technical essence and the achieved result, is accepted as its prototype.

[0011] The disadvantages of this device include its inability to autoclave to ensure infection control, its inability to reuse, and its bulkiness, which is necessary due to the fragility of the polymer. The above-mentioned procedures require the use of a dental burr, which, when rotating, can damage the internal soft tissues of the maxillofacial region, as well as the surgeon's hands.

[0012] The objective of the utility model is to create a reliable protector that can be used with commercially available dental surgical tips, which will ensure safety not only during operations, but also infection safety, by ensuring the possibility of autoclaving the claimed protector.

[0013] The essence of the claimed technical solution is expressed in the following set of essential features, sufficient to solve the technical problem indicated by the applicant and to obtain the technical result provided by the utility model.

[0014] According to the utility model, a protector for an angular dental surgical tip, containing means for securing the dental surgical tip in it, characterized in that the means for securing the dental surgical tip in it are made in the form of a supporting hollow tube, to which two rings are coaxially attached - a main support ring in the form of a straight cylinder with an internal thread, inside which a fixing tip element with a mating thread is placed, and a rear support ring in the form of a conical cylinder inside which a thrust insert with a centrally symmetrical protrusion fixing the tip is placed, wherein the fixing tip element and the thrust insert with the protrusion fixing the tip are provided with through coaxial holes for the drive shaft of a cutter, provided with a protective element of the cutter, wherein the supporting tube is attached to the main support ring and to the rear support ring,in addition, the carrier tube is attached with one end with an open cavity opening to the protective element of the cutter, and its other open end is connected to the means for feeding irrigation fluid into its cavity.

[0015] Furthermore, the claimed technical solution is characterized by the presence of a number of additional optional features, namely:

[0016] - all protector parts can be made of stainless steel;

[0017] - All parts of the protector can be provided with anti-glare coating for the surgeon's eyes during surgery.

[0018] The technical result is to increase the convenience and safety when using the protector during surgical operations, reducing the possibility of damage to the internal soft tissues of the maxillofacial region, as well as the hands and eyes of the surgeon during operations, and ensuring infection safety due to the possibility of autoclaving the claimed protector.

[0019] The essence of the utility model is explained by drawings, where Fig. 1 shows a view of the claimed protector from above, Fig. 2 shows a general view of the protector with a fixing element, Fig. 3 shows a general view of the protector in working condition with a cutter and a fixed tip.

[0020] In the drawings, the following positions are indicated: 1 - supporting hollow tube, 2 - protective element, 3 - main support ring, 4 - fixing tip element, 5 - rear support ring, 6 - thrust insert, 7 - centrally symmetrical fixing protrusion, 8 - cutter drive shaft, 9 - cutter, 10 - dental surgical tip.

[0021] The claimed protector for the angle dental surgical handpiece works as follows.

[0022] Work with the declared protector is carried out as follows. Dental surgical tip 10 is installed between the main support ring 3 and the rear support ring 5. The shaft of the disk cutter 9 is passed through the fixing tip element 4. Then, by rotating the fixing tip element 4, as well as due to the stop insert 6 and the fixing protrusion 7, a tight fixation of the tip 11 between the main support ring 3 and the rear support ring 5 is ensured. A system for delivering saline solution to the surgical area is attached to the end of the supporting tube 1, and the cutter 9 is installed on the shaft 8.

[0023] During operation, the surgeon presses the machine's pedal, which rotates the cutter 9 via the motor, tip 10, and shaft 8. Irrigation fluid is supplied to the surgical area through a cavity in the carrier tube 1. Protective element 2 covers the cutter 9, protecting the patient's tissue and the surgeon's fingers from damage.

[0024] The claimed device can be implemented using known equipment, technical and technological means.
