Description

Technology area

The utility model relates to dental surgery and can be used for fixing soft tissues (membranes) during guided bone regeneration.

State of the art

Known is a set of surgical instruments "Mesh Bone Tack Kit", which includes a pin (clamp), which is designed to fix soft tissues and, accordingly, a pin holder, where the pin is made in the form of a pointed stud with a rounded hat, and the pin holder is made in the form of an oblong rod and with the possibility of attaching a pin gripper head, as well as a hammer, at one end of it.

Also known is a set of instruments for fixing soft tissues "Frios FixationSet, Densply, Implants, Germany", which includes, in particular, pins with a rounded hat in the form of a pointed nail, a milling cutter, pin holders and a hammer.

The disadvantage of the known pins is that they are inserted into the bone solely with the help of a hammer blow, which causes discomfort in the patient. In addition, after inserting the pin into the bone, to detach the pin holder, it becomes necessary to tilt it slightly, which weakens the pin inserted into the bone or simply withdraws it, even if the pin holder is not tilted. This is because inserting the pin into the bone in this manner requires the head holding the pin to hold it fairly tightly. In addition to the above, with a harder bone, to fix the tissue with a known pin, it is necessary to open the hole in the bone in advance, which is rather difficult in hard-to-reach places.

Modern technology for fixing known pins with pin holders in most cases requires the use of separate elements to hold the pin in the bone when removing the pin holder, which in turn complicates the installation of the pin, which is already quite difficult in hard-to-reach places.

Disclosure of a utility model

The task of the utility model is to provide a number of properties, in particular:

1. Minimizing the appearance of patient discomfort when inserting the pin into the bone;

2. Ensuring easy removal of the pin holder after inserting the pin.

These tasks are solved by the fact that, according to the utility model, in a surgical pin made in the form of a pointed stud with a rounded hat, the rounded hat is made in the form of two coaxial disks superimposed on each other, the diameter of the upper one of which is less than the diameter of the lower one, and the point of the nail is made in the form the correct pyramid.

According to a specific embodiment of the invention, the side surface of the disc with a smaller diameter is made in the form of a conical surface facing upward with a large diameter.

According to another variant of the specific implementation of the utility model, the nail point is made in the form of a triangular or quadrangular regular pyramid.

According to another embodiment of the invention, the sides of the base and the side faces of the regular pyramid are concave.

The tasks are also solved by the fact that, according to the utility model, in a pin holder containing a handle and a tip for capturing the pin, the tip for capturing the pin is removable, with the ability to connect to the handle, and the handle is made in the form of an oscillator with the ability to transmit rotational-oscillatory motion to the tip.

According to a specific embodiment of the invention, the inner surface of the edge of the pin gripping tip is designed as a side surface of a disc with a smaller diameter of the pin hat.

In comparison with known instruments, the proposed solution eliminates the need to insert the pin into the bone tissue with a hammer blow, which leads to a sharp decrease in patient discomfort. In addition, the proposed design of the pin makes it possible to easily remove the pin holder after inserting the pin, which in turn excludes the weakening of the pin and the use of additional tools.

in fig. 3 is a general view of a pin, a pin holder and a handle in the form of an oscillator.

Implementation of the utility model

The dental pin is made in the form of a pointed stud (1), which has a hat in the form of two coaxially superimposed discs (2) and (3), of which the upper (3) has a smaller diameter. The tip (4) of the nail (1) is made in the form of a regular pyramid. According to a preferred embodiment, the point of the nail is made in the form of a triangular or quadrangular regular pyramid, and the sides (5) of their base and side edges (6) can be made concave. After easy and reliable insertion of the pin hat into the tip of the pin holder (7) and inserting the pin into the bone tissue, the disk of the pin hat with a small diameter (3) is made with a lateral conical surface directed upward with a large base to remove the pin holder, as shown in Fig. 2.

The pin holder has a tip (7) holding the pin hat and a handle (8), which is made in the form of an oscillator. The tip (7) is separable (removable), that is, at one end it can be inserted into the oscillator (8), which, during operation, transmits to the tip rotational - oscillatory movements. The inner surface of the tip is formed in accordance with the side surface of the top disc (3) of the pin hat, as shown in FIG. 2.

In order to fix the soft tissue, the tip (7) of the pin holder is pressed onto the pin hat by pressing. The disc (3) with a small diameter enters the pin holder (7), and the tip edges "sit" on the lower side surface of the disc (2) with a large diameter. Then the pin holder (7) is inserted into the oscillator, which provides rotational - oscillatory movements. With the help of rotational - oscillatory movement and pressure, the pin shaft is inserted into the bone tissue, thereby ensuring the fixation of the membrane. Then the tip (7) is removed by tilting the pin holder in any direction relative to the axis of the stud. At the same time, one edge of the tip holds the pin in the inserted state into the bone, thus preventing its loosening or withdrawal from the bone.

The design of the proposed pin makes it possible to provide several advantages, in particular:

1. The pyramidal design of the pin point and insertion into the bone tissue by means of a rotational-oscillatory motion helps to increase the efficiency of the process and to incomparably less discomfort for the patient. In addition, the implementation of the concave sides of the base and the lateral faces of the pyramidal tip of the nail, as well as the introduction of the pin using rotational - oscillatory movements, makes it possible to insert the pin into the harder bone tissue without preliminary drilling a hole, eliminating the winding of the soft membrane on the pin shaft.

2. Eliminates the need for additional steps, as well as the use of additional instruments and fasteners, thereby reducing the duration of surgery as much as possible.

3. To fix the pin in the pin holder and to hold it during insertion into the bone tissue, a relatively rigid connection with the pin holder head is not required, since during pin insertion the main pressure falls on the outer edge of the pin cap, which in turn keeps the pin in position necessary balance.
