UA150993U - Fixer plate holder for temporary locking of a growth zone of the long limb bones - Google Patents

Abstract

The utility model relates to a fixer holder for temporary locking an extensor zone of the long limb bones, which includes branches with racks, finger rings and working grips containing teeth for fixing a fixer plate in a convenient position.

Description

A useful model relates to medicine, particularly to medical instruments used in surgery, and can be used to hold a retainer plate to temporarily block the growth zone of the long bones of the limbs.

A known needle holder which can be used to hold a locking plate for temporary blocking of the growth zone of the long bones of the limbs, having two branches with racks, a lock and finger rings, working jaws, characterized in that the working surface of one of the jaws contains six pins , located in two rows in a staggered order, on the other sponge, according to the pins, six grooves are placed, which, when connected to the pins and closing the branch, keep the needle in its initial position. (Pat. 65087 OA).

Disadvantages of the specified needle holder are insufficiently reliable fixation of the plate with the working jaws of the tool (slippage during manipulation in soft tissues) and holding of the plate in an inconvenient position for installation.

The task of the useful model is to create a retainer of the fixator plate for temporarily blocking the growth zone of the long bones of the limbs (retainer), which will increase the convenience of spatial manipulation of the plate and its maintenance in the correct position during installation, and the accuracy of the installation of the plate.

The task is solved by the fact that the holder of the fixator for temporarily blocking the growth zone of the long bones of the limbs contains branches with racks, finger rings and working jaws, according to a useful model, the upper jaw contains two teeth located on the sides, and the lower jaw contains one tooth in the centers, which are made with the possibility, when attached to the plate, to be placed in the corresponding grooves on it, reliably fix the plate of the retainer in a convenient for installation position at an angle (1307).

Such a feature of the inner surfaces of the working jaws of the device (tooth-groove connection) completely eliminates the mobility and displacement of the retainer plate holder during operation.

The useful model is explained by the drawings (Fig. 1, Fig. 2), where: 1, 2 - branches, Z ring for fingers, 4 racks, 5 upper working sponge, 6 lower working sponge, 7 teeth of the upper working sponge, 8 tooth of the lower working sponges, 9 retainer plate.

The device is used as follows:

The holder is taken by the finger rings 4, open the working jaws 5, b, and insert between

With them, the retainer plate 9 for temporarily blocking the growth zone of the long bones of the limbs in such a way that the teeth 7, 8 on the working jaws 5, 6 coincide with the grooves on the plate. By closing the retainer, the plate 9 is clamped and a stable retainer-plate complex is obtained, with the help of which it is possible to subcutaneously manipulate the plate 9, holding the retainer by the rings

From branches 1, 2.

Thus, the retainer of the fixator for temporarily blocking the growth zone of the long bones of the limbs allows to achieve an increase in convenience when blocking the growth zone, as it reliably fixes the plate in all planes, which reduces the duration and trauma of the surgical intervention.
