Abstract

The invention relates to medical technology. The purpose of the invention is to reduce the trauma of the dilution of soft tissues during bone operations by increasing the reliability of fixing the working jaws in the surgical wound. The retractor contains elastic plates 6 and 7 and tissue wrappers in the form of connecting pins 17 and 18 with working parts in the form of threaded cones, by means of which the pins 17 and 18 are screwed into the bone tissue, which ensures tissue dilution by plates 6 and 7. 2 з п. f-ly, 4 silt

The invention relates to medical technology, namely to the retractor

The purpose of the invention is to reduce the trauma of the dilution of soft tissues during bone operations by increasing the reliability of fixation of the working jaws in the surgical wound.

FIG. I shows the retractor, top view in working position; in fig. 2 is a section A-A in FIG. one; in fig. 3 - working device sponges, side view; in fig. 4 is a section BB in FIG. 3

The retractor contains curved branches 1 and 2 that are hingedly connected with hands 3 and 4, a slider lock 5,

Tsemi 12 and 13, change their orientation and move relative to the connecting pins 17 and 18, which, in addition to the elasticity of the plates B and 7, provides the possibility of diluting the removable working parts to the optimal size of the surgical field.

Claims (3)

Invention Formula S 1. Retractor, containing two articulated bent branches with handles, creamer lock, removable working jaws located in mounting slots with the possibility removable working jaws in the form of elastically interacting with locking elements of the soft plates 6 and 7, provided with oval and tissue fixatives, characterized in that, in order to reduce the morbidity of the dilution of soft tissues during bone operations by increasing the reliability of fixing the working sponges in the surgical wound, loops 8-11 with ends 12 and 13, mounting slots in the form of through slots 14, as well as locking elements 15 and 16 and tissue fixers in the form of connecting pins 17 and 18, and the elastic 20 working jaws are made in the form of elastic plates 6 and 7 can be made in the form of metal springs, and fabric fixers in the form of connecting pins 17 and 18 with working parts in the form of thread plates that can be deformed perpendicular to the plane of movement of the branches and provided with oval loops at the ends, installed with These are cones 19 and 20 and restrictive 2c possibilities for interaction between themselves with bargaining heads 21 and 22 on non-working parts. Retractor works as follows. After processing the operative field and isolating it with sterile material, the procuracy is arranged perpendicular to the elastic plates, moreover, the height of each loop is equal to half the width of the elastic plate, and the inner surface of each loop is adapted to intersect skin dissection and dilute the 30 actions with non-working parts soft tissues to provide access to the surgical site (e.g., cervical vertebrae). Then, removable working jaws are inserted into the wound and secured with locks of tissues, which are woven in the form of connecting pins, while the mounting slots are located on elastic plates and made in the form of through slots. 2. The retractor according to claim 1 is characterized in the form of connecting pins 35, in that the elastic plates are made 17 and 18 by screwing the thread cones 19 and 20 into the bone tissue. Removable working jaws, made in the form of elastic plates 6 and 7, are connected with curved branches 1 and 2, using mounting slots made in the form of through slots 14 and fixed with locking elements 15 and 16. The elastic plates 6 and 7 are separated by handles 3 and 4 to the required value of the operating floor and fic Yen in the form of metal springs. 3. Retractor according to claim 1, characterized in that the fixings of fabrics are made in the form of connecting pins with working parts in the form of threaded cones and non-working parts with restrictive heads, and the sizes of large bases of cones oriented to restrictive heads and the sizes of restrictive heads exceed internal They are mounted with a kremalerny lock 5. When the 45 are developed, the transverse dimensions of the loop ovals, with the elastic plates 6 and 7, the oval loops of this non-working parts are less than 8-11, interacting with each other the torus-transverse dimensions of the ovals. Tsemi 12 and 13, change their orientation and move relative to the connecting pins 17 and 18, which, together with the elasticity of the plates b and 7, provides the possibility of diluting the removable working parts to the optimum size of the surgical field. Invention Formula plates arranged for deformation perpendicular to the plane of movement of the branch and provided with oval loops at the ends, installed with the possibility of interaction between each other with ends that are perpendicular to the elastic plate, moreover, the height of each loop is equal to half the width of the elastic plate and the inner surface of each loop is made able to interact with non-working parts of fixers fabrics made in the form of connecting pins, while the installation slots are located on the elastic plates and made in the form of through-slots. 2. The retractor according to claim 1, distinguished 0 Yen in the form of metal springs. 3. Retractor according to claim 1, characterized in that the fixings of fabrics are made in the form of connecting pins with working parts in the form of threaded cones and non-working parts with restrictive heads, and the sizes of large bases of cones oriented to restrictive heads and sizes are limited 1 /four H- / 5 Rig.2 Fig.Z
