RU212938U1 - Device for isolation of the surgical field during surgical manipulations on the alveolar processes of the jaws - Google Patents

Abstract

The utility model relates to medicine, namely to surgical dentistry, and can be used to protect against the ingress of blood and saliva into the surgical wound during surgical interventions on the alveolar processes of the jaws.

The technical result of the utility model is the simplification of the application of the device and the isolation of the surgical field from saliva and tongue, which, with spontaneous movements, contributes to the ingress of saliva onto the surgical wound on the alveolar process of the jaws. In addition, the part that passes to the hard palate, due to the springy properties of silicone, prevents the mouth from closing. At the same time, the jaws are not in a static position, which is favorable for the temporomandibular joint.

Description

The utility model relates to medicine, namely to surgical dentistry, and can be used to protect against the ingress of blood and saliva into the surgical wound during surgical interventions on the alveolar processes of the jaws.

Most dental surgical procedures in the mouth are performed in conditions of isolation of the operating field from saliva for quite a long time. As experience shows, not many dentists pay due attention to the problem of isolating the surgical field from saliva, although this is an indispensable condition when working to reduce the risk of complications.

It is known "Device for isolating treated teeth" (Patent RU No. 2675549, IPC A61C 17/06 - 16.03.2018, Bull. No. 08) contains a tension panel made of elastic material and two controls located at opposite ends of the tension panel. The tension panel is made with the possibility, when in the first, stretched, state, obtained as a result of the removal of the controls from each other in the direction of stretching, insertion from the side of the occlusal surface into at least one interdental space. In the second state, after insertion into at least one interdental space, it is made with the possibility of a snug fit to the gum area located between the teeth and to the proximal surfaces of the teeth forming at least one interdental space, and in the second state, each of the controls is adjacent to at least one tooth and/or to the surrounding gum and between the two controls, at least one strap is provided, passing in the plane of at least one jumper and made for insertion into the interdental space adjacent to the interdental space , scheduled for the introduction of at least one jumper.

The disadvantage is the inconvenience of use in surgical operations on the alveolar processes of the jaws, as the device closes the operating field.

Known "Intraoral dental aspiration and isolation system" (Patent RU No. 2659012, IPC A61C 17/00 - 16.01.2018, Bull. No. 02), made of a flexible material containing

a main body part comprising a formed pocket with a front wall, a back wall and a side wall between the front wall and the back wall, the front wall, the back wall and the side wall forming the inside of the formed pocket;

a cheek retractor part connected to the main body part;

a suction connector part configured to connect the inside of the main body to the vacuum suction source, the suction connector part being connected to the main body part at an end opposite the cheek retractor part; and a removable mouth spacer comprising a strip configured to fit around the suction connector part, wherein the outer surface of the suction connector part has a cut-out portion corresponding to the strip, and wherein the outer surface of the strip is substantially flush with the remaining outer surface of the suction connector part when the strip is installed in the cut-out area.

The disadvantage is the inconvenience of using during surgical operations on the alveolar processes of the jaws, since the operations are carried out on a field limited by the boundaries of the oral cavity and on the outer surface of the alveolar process, the device only interferes with manipulations.

A device for opening a mouth with a protective function is known (CN patent No. 110251060, IPC A61B 1/24 A61C 19/00 - 09/20/2019), containing two lip supports, which are located on the left and right, characterized in that each lip support is equipped with lip support groove with an opening facing two sides of the oral cavity, the lower ends of the two lip supports are connected by a U-shaped elastic support arm, the upper ends of the two lip supports are connected through an elastic retaining block, the upper end of the elastic fixing block is provided with an arcuate retaining cavity for the nose facing outward from the oral cavity, and the arcuate plate for holding the nasal cavity contains a blocking section of the front end and a transition section for connecting the blocking section and the elastic fixing block.

The disadvantage of this device is that it does not provide for the protection of the soft tissues of the oral cavity from various types of injuries.

Also known oral strut (patents US No. 4053984, IPC A61B 1/24, A61C 17/06, A61C 17/08 - 10/18/1977), which provides the opening of the mouth for dental procedures, while maintaining a dry and wide area of action. The device contains a flexible tubular frame having upper and lower U-shaped sections, which are adapted for installation in the patient's mouth outside the upper and lower dental arches in surface contact with the cheeks. The cheek deflectors are removable between the upper and lower U-shaped frame sections to push the patient's cheeks outward to prevent obstruction of the field of view. The buccal deflectors are made of a flexible material that is bent generally outward to a contour approximating the buccal surface of the mouth. A tongue deflector is attached to the front of the lower U-shaped section of the tubular support frame. The frame is provided with a plurality of holes that allow saliva to be removed from the oral cavity when a vacuum source is applied to the saliva ejector, which is connected to the tubular frame. The top and bottom visors are attached to the front of the top and bottom of the tubular frame.

The main disadvantage of this technical solution is that the tongue reflector does not completely isolate the tongue, which causes inconvenience to the dentist when preparing hard tissues of the teeth, and the design is rather bulky.

The disadvantage of this technical solution is that the tongue fixer in the region of the sixth teeth covers their surface, which causes inconvenience to the doctor when preparing hard dental tissues. Also, this device is made without sufficient protection of the surface of the cheeks, while the density of the material is quite high, which makes it inconvenient to use and, accordingly, gives the patient discomfort during dental procedures.

Known "Device for isolating teeth from saliva during dental interventions" (Patent application RU No. 2003101741, MPKA61C 5/14, A61C 17/06 - 10.09.2004, Bull. No. 25), used individually, made in the form of an elongated flexible monolithic plate , consisting of a central part of a rounded or rectangular shape with double-sided wedge-shaped clamps of different sizes, thickened along the perimeter, attached to them side rectangular parts made with rounded edges, a roller along the outer edges and with a recess for the lip or without a recess for the lip. In the second version, the device is made in the form of an elongated flexible monolithic plate, consisting of a central rectangular plate with rounded edges, connected on one side to a side plate, reduced by 1/3 without a recess for the lip, increased distance between the tops of the wedge-shaped clamp and the side part, and on the other hand, consisting of three wedge-shaped clamps arranged in a row.

The disadvantage is the impossibility and inconvenience when used in surgical interventions on the alveolar processes of the jaws.

This patent is taken as a prototype.

The objective of the claimed utility model is the possibility of isolating the surgical field on the alveolar process of the jaws, which are made mainly on their outer surface in conditions of limitation by the boundaries of the oral cavity.

The technical result of the utility model is the simplification of the application of the device and the isolation of the surgical field from saliva and tongue, which, with spontaneous movements, contributes to the ingress of saliva onto the surgical wound on the alveolar process of the jaws. In addition, the part that passes to the hard palate, due to the springy properties of silicone, prevents the mouth from closing. At the same time, the jaws are not in a static position, which is favorable for the temporomandibular joint.

The technical result is achieved by using a device for isolating the operating field during surgical manipulations on the alveolar processes of the jaws, made in the form of a mono-product, the peculiarity of which is that it is made of medical silicone, for example, manufacturers of Forplast, AlphaGary, Kraiburg, lower part 1 which is made in the form of a curved semi-oval with a thickness of 1.5-2.0 mm and a width of 2.5-3.0 cm, adjacent to the inner surface of the lower jaw with a transition to the bottom of the mouth, and the upper-distal part 2 is made in the form of a dome, passing from both ends of the curved semi-oval to the hard palate.

The essence of the utility model is illustrated by drawings, which show

in fig. 1 - General view of the device;

in fig. 2 - Front view;

in fig. 3 - View of the superimposed device.

The figures indicate the following positions: 1 - the lower part of the device, 2 - the upper distal part of the device.

Implementation of the utility model

The device for isolating the surgical field during surgical manipulations on the alveolar processes of the jaws (Fig. 1, 2) is made in the form of a mono-product made of medical silicone, for example, manufacturers of Forplast, AlphaGary, Kraiburg, the lower part 1 of which is made in the form of a curved semi-oval with a thickness of 1.5- 2.0 mm and a width of 2.5-3.0 cm, adjacent to the inner surface of the lower jaw with the transition to the bottom of the mouth, and the upper-distal part 2 is made in the form of a dome, passing from both ends of the curved semi-oval to the hard palate.

A device for isolating the surgical field during surgical manipulations on the alveolar processes of the jaws works as follows. The device is applied to the inner surface of the lower jaw. At the same time, the tongue is located in the bed, which isolates the surgical field from blood and saliva, and the palatal and lateral surfaces of the device prevent complete mouth closure, while maintaining a small range of motion, which favorably affects the state of the articular ligaments and interarticular disc. If necessary, you can also put gauze napkins under the bed.

Thus, the claimed Device for isolating the surgical field during surgical manipulations on the alveolar processes of the jaws, compared with the prototype, has a simpler technique for imposing and isolating the surgical field during surgical interventions.
