LV11280B - Device for injection of cells suspension into body - Google Patents

Abstract

The syringe for injecting fat cell suspension into an organism during plastic surgery is equipped with a removable tip with a cell evacuation groove. The tip is placed between the holder stands, the base of which is fitted with two guides and a movable plate.

Description

SUSPENSION INSTALLATION ORGANISM.

The present invention relates to medical technology, specifically to the development of medical instrumentation and devices for use in reconstructive and plastic surgery.

Reconstructive and plastic surgery deals with modeling and reconstruction of the breast, face and other parts of the body. Reconstructive operations require specially designed tools, as they are required for high quality and cosmetic effects of plastic surgery.

There are known sets of tools, devices, endoprostheses of various companies for use in reconstructive operations. Frequently used Dav Corning (USA) kits. Breast implants made of silicone rubber. They are executed as seamless tanks of thin film filled with gel-like substance. The implant is round in shape with a flat round base. However, excessive formation of a fibrosis capsule around the prosthesis is observed, leading to increased breast density and, in 40% of cases (i), psychological dissatisfaction.

Breast reconstruction is a known pap smear that is performed by piercing the skin and applying a gel. A device for administering a gel-like suspension to the body, comprising a perfusion syringe (2), for this reconstructive operation.

This device is a prototype of the invention.

However, when administering the gel, the constructive fibrosis of the capsule around the gel should also be noted, and in many cases the inflammatory process begins.

It is possible to do breast reconstruction using a suspension of fat cells. However, the administration of the fat cell suspension via the prototype fails because the administration of the suspension requires a great deal of effort (about 50-80 kg) which renders the prototype device invalid.

The object of the invention is to provide a device for the administration of a suspension of fat cells in the body which would allow to reduce the trauma of the patient and prevent the syringe from going out of the box during reconstructive surgery.

The objective is achieved by the syringe having a removable removable nozzle in the form of a tube with a groove for the exit of tissue cells and positioned between the struts of the bracket to which the nozzle is attached, a profiled recess Contains two rails to which a movable plate is attached which can be fixed in relation to the rails. A dismountable syringe plunger disk is mounted in the center of the plate and is movable.

The invention is explained by a drawing, wherein FIG. i shows an overview of the device.

The device includes a perfused syringe for injecting 1 fat cell suspension into the body during reconstructive surgery, such as breast surgery.

The syringe contains a removable removable attachment cap 2.

The nozzle is a hollow tube, the locking plate 3 of which at the distal end is closed and rounded. A circumferential groove 4 is provided on the surface of the tube at the distal end. The nozzle, together with the syringe, is mounted on the bracket 5. A syringe body is located between the last posts 6. On the base of the bracket 7, which is executed in the form of an oval recess with a recess, profiled as a collar of the syringe body.

Such a bracket-syringe body holder design prevents it from falling out of the box during operation.

Opposed on the opposite side of the base plate 7 are two conductive cores 9 on which, with relative displacement, a plate 10 is arranged, fixed to them by means of a clamping screw 11.

In the center of the plate is an opening containing the syringe plunger clamp assembly, in the form of an axis 12 with a handle 13 on one end and a removable syringe plunger disc 14 on the other.

The device works as follows.

The fat cell suspension is drawn into the perfused syringe 1. On the syringe 1, attach the tip 2, which is secured with the syringe to the plate 5, 7 between the bracket struts 6. The syringe plunger head is secured to the disc clamp 14 by detaching the clamp half. The plate 10, in which the axial handle 12 moves, is then fixed on the guide 9 with the syringe plunger head clamped. Tip 2 is inserted into the pre-selected plastic modeling area of the body. It is then pushed on the handle 13, pushed the plunger of the syringe forward and introduced into the body a suspension of fat cells. The clamps of the locking plate 10 are released, the plate 10 moves downwards and is fixed again. Press on handle 13 and continue to insert fat cells.

If necessary, syringe 1 may be replaced and administration of the fat cell suspension may continue.

When applying a suspension of fat cells, the force applied to the handle 13 to overcome the resistance of body cells amounts to 50 to 30 kg.
