Description

The invention relates to medicine, in particular to traumatology, orthopedics, oncology.

Known neurosurgical perforator for embolization of tumors (RF Patent No. 2233131, IPC A61B 17/34, A61M 31/00, publ. 07/20/2002, bull. No. 20), which contains a handle and a main tubular body with an end sharpening. The rotary hammer is equipped with an additional tubular casing of a special design, which has a connecting element at the non-working end for interconnection with a source of negative pressure.

A disadvantage of the known neurosurgical perforator is the absence of support sites for fixing the tumor, precluding the use of such an instrument with elastic tension of the tumor during surgery, in which it is possible to leave fixed fragments of the tumor in the wound.

A device for removing intraocular tumors is known (RF Patent No. 23762, IPC A61F 9/00, publ. 07/20/2002, bull. No. 20), containing a tip in the form of a tube with a closed end and a window in the wall and installed in it coaxially with rotation the inner tube with the cutting part, the tip window is made starting from the middle of the end face in a plane located at an angle of 30-45 ° to the longitudinal axis of the device, while the end face of the window is sharpened and at least one of the side faces is bent inward and sharpened, and the cutting part of the inner tube on ground end and at least one ground side faces.

The disadvantages of this device are: increased invasiveness of the rotating inner tube with a cutting side face on the tumor, as well as the lack of transparency of the tubes, which does not allow to fully visualize the process of removal of the tumor.

The technical result of the invention is to reduce the likelihood of developing a relapse of the tumor, improving the quality of life of patients, reducing the period of rehabilitation after surgery.

The specified technical result is achieved by the fact that in the device for removing soft tissue tumors containing the inner and outer cylinders, according to the invention, the outer cylinder is made with holes and has a support pad with an oblique cut in diameter at its lower end and an internal thread at the upper end, while the inner cylinder made with holes and has a support pad with a perpendicular plane in diameter at one end of the cylinder and an external thread at the other end, with which the internal and external th cylinder.

A device for removing soft tissue tumors is illustrated by drawings, where in FIG. 1 shows a general view of the device, FIG. 2-5 - details of the device in operation.

The device for removing soft tissue tumors has an outer cylinder 1 of transparent organic glass with holes, a support pad 2 with an oblique cut in diameter at one end for fixing the tumor and an internal thread 3 at the other end for the cylinders to move along the thread. The inner cylinder 4 is made of transparent organic glass with holes, a support pad 5 with a perpendicular plane in diameter at one end of the cylinder for fixing the tumor and an external thread 6 for the movement of the cylinders along the thread and roughness on the plane of the cylinder 7 to hold the device by hand. The hole 8 at the other end of the cylinder is a guide for the injection needle when performing a puncture of the tumor and taking the liquid contents from the inner cylinder.

The essence of the invention lies in the fact that the device for removing soft tissue tumors contains an outer and inner cylinder that fixes longitudinally the tumor along the thread during surgery and acts as a container (in color and composition of the tumor) when removing the soft tissue tumor of the musculoskeletal system.

When performing the operation - surgical access to the selected apex of a soft tissue tumor of the musculoskeletal system, an external cylinder 1 is applied by a supporting pad 2 to the top of the tumor, pressing and moving the tumor inside the outer cylinder. Inner cylinder 4 along threads 3, 6 by rotational movements along

performing the function of a container (according to the color and composition of the tumor) when removing a soft tissue tumor of the musculoskeletal system.

When performing the operation - surgical access to the selected apex of a soft tissue tumor of the musculoskeletal system, an external cylinder 1 is applied by a supporting pad 2 to the top of the tumor, pressing and moving the tumor inside the outer cylinder. The inner cylinder 4 along the threads 3, 6 is moved relative to the outer cylinder 1 by rotational movements along the rough plane 7, and the support pad of the inner cylinder 5 of the tumor top is fixed — the support pad 2 of the outer cylinder. With rigid fixation of the apex of the tumor through supporting platforms 2, 5 and threads 3, 6 of the outer 2 and inner 4 cylinders, elastic tension of the tumor and complete surgical removal of the soft-tissue tumor with the fixation device on the tumor without rupture of the tumor walls followed by suturing the wound take place.

When removing soft tissue cysts due to the upper hole 8 of the inner cylinder 4, a tumor is punctured with an injection needle followed by evacuation of the liquid contents from the cylinder.

Due to the transparency, closeness and integrity of the outer cylinder 1 and the inner cylinder 4 allows you to determine the color, structure and composition of the soft tissue and liquid components of the tumor and to prevent the loss of components of the tumor in the wound.

The described device eliminates the recurrence of the tumor, provides reliable fixation of the tumor in the wound, quick and less traumatic removal of the soft tissue tumor, simple in execution, can be reused.
