RU98897U1 - DEVICE FOR SACRED CUTTING OF THE MUSCLE TENDONS, CAPSULES OF THE JOINTS DURING STOP DEFORMATIONS - Google Patents

Abstract

 1. A device for subcutaneous dissection of tendons and capsules of joints on the foot, comprising a body in the form of a rod with a pointed end, characterized in that the body is made with a longitudinal cavity and a damped distal end, a threaded rod is installed in the body, interacting with a guide sleeve located in at the proximal end of the body, on the distal portion of the threaded rod, a holder is made, made in the form of a nut, to which two cutting elements that exit when the rod rotates from odolnyh oppositely disposed grooves in the housing. ! 2. The device according to claim 1, characterized in that a handle is mounted on the proximal end of the threaded rod.

Description

The utility model relates to the field of medicine, namely to devices for correcting deformities of the foot (equino-varo-adduction, flat-valgus), is intended for subcutaneous dissection and lengthening of shortened tendons (for example, the Achilles tendon), dissection of capsules of joints (for example, the ram-navicular, scaphoid-wedge-shaped joints).

Known scalpel containing a handle and a cutting part (1).

The disadvantage of this scalpel is the inconvenience and complexity of use, the inability to dissect the subcutaneous structures of the foot without extensive separation of the skin.

Known surgical instrument containing a housing made in the form of a rod with a pointed end (2).

The disadvantage of this tool is the inability to use it for dissecting tendons and capsules of the joints of the foot.

A device for dissecting tissues, containing a handle with a rod with a cutting element (3).

The disadvantage of this device is the inconvenience and complexity of its use when dissecting tendons and capsules of the joints of the foot.

Also known is a device for dissecting tissues, comprising a body in the form of a rod with a pointed end (4).

The disadvantage of this device is the increased complexity when dissecting tendons and capsules of joints on the foot.

The purpose of creating a utility model is to reduce the complexity of dissecting tendons and capsules of joints on the foot with minimal damage to the skin.

This is achieved by the fact that the utility model housing is made with a longitudinal cavity and a damped distal end, a threaded rod is installed in the housing, which interacts with a guide sleeve located at the proximal end of the housing, and a holder made in the form of a nut is installed on the distal portion of the threaded rod two cutting elements pivotally mounted pivotally protruding when the shaft rotates from longitudinal opposed grooves in the housing, and at the proximal end of the threaded rod grip.

Comparison of the proposed device with others known in the field of medicine, showed its compliance with the criteria of a utility model.

Figure 1 shows the device in its original state, figure 2 - in working condition.

The device comprises a housing made in the form of a rod 1 with a longitudinal cavity 2 with a muffled distal end 3 and a pointed end 4. In the housing 1 there is a threaded rod 5 interacting with the sleeve by a guide 6 mounted in the proximal end of the housing 1.

A holder 7 is mounted on the distal portion of the shaft 5, made in the form of a nut, to which the cutting elements 8 and 9 are pivotally mounted, which, when the shaft 5 is rotated, extends for a handle 10 located at the proximal end of the shaft 5 from longitudinal opposed grooves 11 and 12 on distal portion of the housing 1.

For subcutaneous dissection of tendons and capsules of joints on the foot, the device is used as follows.

The device in the initial state (Fig. 1) pierces the skin on the foot in the projection of the tendon (e.g. Achilles) or capsule of the joint (e.g. ram-navicular or other) to a predetermined depth. Rotate the rod 5 by the handle 10, while the guide 7 moves along the threaded portion of the rod 5 to the distal end of the housing 1, the cutting elements 8 and 9 come out of the grooves 11 and 12. Sawing the cutting elements 8 and 9, subcutaneously dissect the desired anatomical formation on the foot (joint capsule or tendon). By rotating the handle 10, the cutting elements 8 and 9 are removed into the housing 1, and the device is removed from the patient’s foot.

The positive effect of using the device is expressed in reducing the complexity of subcutaneous dissection of tendons and capsules of joints on the foot.

The device is advisable to use in the correction of foot deformities, for example, equino-varo-adduction or flat-valgus, for subcutaneous dissection of shortened anatomical structures of the foot (tendons and capsules of joints), followed by redress and removal of the foot to the correct position. The greatest positive effect from the correction of a deformed foot, after subcutaneous dissection of shortened, anatomical structures of the foot, will be achieved in children in young children (from 1 to 3 years), which is due to age-related features of the anatomy of the foot.
