Description

The invention relates to the field of medicine.

Known operating device containing a table with racks and articulated supports with grooves, installed in the grooves of the thrust with a screw thread, bearing mirrors and drive nuts - patent RU 2363401 C1, A61B 17/02 on the "Ranorashitel", published: 10.08.2009,

According to its features and the achieved result, this device is closest to the claimed one and is taken as a prototype.

In this device, threaded threaded rods are made in the form of screws installed in the grooves of the hinged supports.

A disadvantage of the known device is the forceful abduction of the edges of the anatomical formations of the surgical wound, controlled by the individual sensations of the operating surgeon, associated with a significant probability of injury to the edges of the surgical wound and internal organs (liver, bladder, uterus, etc.) of the patient. In addition, during the rotation of the drive nuts, it is possible to rotate the screws with an undesirable shift with the mirrors at the edges of the wound of the patient.

The technical result of the proposed invention is the expansion of the technological capabilities of the operating device and the exclusion of trauma to the tissues of the surgical wound and internal organs of the patient during their fixation.

The specified technical result is ensured by the fact that in the operating device, made in the form of a table with racks and articulated bearings with grooves installed in the grooves of the threaded rods, bearing mirrors and drive nuts, according to the invention, the device is equipped with spring dynamometers installed between the articulated supports and drive nuts on rods made with guide flats adjacent to the sides of the grooves and provided with nodes for fixing dynamometers in the working position, made in the form of nuts, races laid on the rods at the hinge supports from the side of the mirrors.

The essence of the proposed technical solution is illustrated by drawings, where:

figure 1 - shows a General view of the operating device from one edge of the table;

figure 2 - node drive traction with a dynamometer.

figure 3 - operating device in axial section along the thrust normal to her flats.

The operating device comprises a table 1 with racks 2 and articulated supports 3 with grooves 4, thrust 5 with screw thread 6 installed in them, bearing mirrors 7 and drive nuts 8.

The device is equipped with spring dynamometers 9 mounted on rods 5 between the hinge supports 3 and drive nuts 8. The rods 5 are made with flats 10 adjacent to the sides 11 of the grooves 4. The device is equipped with nodes for fixing the spring dynamometers 9 in the working position, made in the form of nuts 12 located on the rods 5 at the hinge supports 3 on the side of the mirrors 7. The dynamometers 9 are made in the form of a support cup 13 with a scale A, a pressure cup 14 and a spring 15 between the stops 16, 17 of the said cups 13, 14. Moreover, in the stops 16, 17 grooves 18, 19 are made ootvetstvenno adjacent the dihedron 10 rods 5 than cranking excluded dynamometers 9 relative rods 5 during rotation of the drive nuts 8.

When operating the operating device for opening the operating wound, the racks are fixed with 2 screws 20 on the table 1 in a position convenient for the operation, and mirrors are installed on the edges of the patient’s wound 7. Then, by alternating rotation of the drive nuts 8, the edges of the patient’s wound are removed (open the wound) with force control dynamometer 9 in kgf:

3.26 - for normosthenic;

3.49 - for asthenic;

3.21 - for hypersthenic, that is, depending on the constitutional type of the patient (which made it possible to objectively control the loading of the edges of the patient’s surgical wound when it is opened) and then, by turning the nuts 12 all the way into the hinged supports 3, dynamometers 9 are fixed (turned off) in the working position (which excludes the effect of the springs 15 dynamometers 9 during the operation on the edges of the wound of the patient with the exception of the likelihood of further uncontrolled disclosure)

At the end of the operation, when the patient is released from the operating device, the drive nuts 8 are first unscrewed until the load is completely removed from the springs 15 of the dynamometers 9 with the possibility of further free atraumatic manipulation of the device elements.

The operating device in comparison with the prototype has advanced technological capabilities and, thanks to the control of the efforts to open the wounds of the patient and turning off the dynamometer spring, reduces his injury during the operation.

Claims (1)

An operating device comprising a table with racks and articulated bearings with grooves, mounted in the grooves of the threaded threaded rod, bearing mirrors and drive nuts, characterized in that the device is equipped with spring dynamometers installed between the hinged supports and drive nuts on rods made with guide flats adjacent to the sides of the grooves, and is equipped with nodes for fixing the dynamometers in the working position, made in the form of nuts located on rods at the hinge supports on the side of the mirrors.
