RU44488U1 - RETRACTOR FOR RHINOPLASTY FROM ORAL-ANTI-PRE-OPERATIVE ACCESS - Google Patents

Abstract

The retractor for rhinoplasty from oral-vestibular operative access consists of a working part made of stainless steel with a chrome metal coating, including supporting and correcting platforms combined with each other by means of a latch and plate hooks placed on them, the linear movement of which is provided by the return ones springs abutting on the supporting platform, and guides of the rod hooks with through guide holes, and the fixing part, which is an elastic belt, the length of which can be adjusted by the belt clip, in accordance with the diameter of the patient’s head.

Description

The utility model relates to medical equipment, namely to the group of pushing instruments for rhinoplasty from oral-vestibular operative access.

Among the medical instruments there are various pushing mechanical devices (O ′ Sullivan – O ′ Connor, Cooley, Kirchner, Colin, Mayo – Adams retractors) used in abdominal, thoracic, gynecological surgical interventions [Topographical anatomy and surgical surgery. Ed. Acad. RAMS Yu.M. Lopukhina., Moscow, GEOTAR - MED, 2001, p.31-35]. However, their design does not allow their use in rhinoplastic surgery.

Currently, with rhinoplastic surgical interventions and, in particular, with oral-vestibular operative access to the bone-cartilage structures of the external nose, lamellar Farabef dilators, serrated Volkmann hooks, nasal mirrors are used [Topographic anatomy and operative surgery. Ed. Acad. RAMS Yu.M. Lopukhina., Moscow, GEOTAR - MED, 2001, p.31-35; Piskunov G.Z., Piskunov S.Z. Clinical rhinology. M .: "MIKLOSH", 2002., S. 324-374]. However, these tools require the mandatory presence of an assistant surgeon, do not allow for reliable retention of the skin of the nose

with constant effort, in a given position, with minimal trauma.

The goal achieved using the utility model is to ensure the optimal field of action of the surgeon in the area of the operation without the additional participation of an assistant, to protect the surrounding tissues from accidental damage, with rhinoplasty from oral-vestibular operative access.

This goal is achieved by the fact that the retractor for rhinoplasty from the oral-vestibular operative access contains a fixing part and a working part with a supporting and corrective platform located on it having guides in which plate hooks are moved by means of the reverse spring traction.

Figure 1 shows a retractor for rhinoplasty from oral-vestibular operative access, General view; figure 2 - the same, in working condition.

The retractor for rhinoplasty from oral-vestibular operative access contains a working part 1 made of stainless steel with a chrome metal coating, consisting of a supporting 3 and correcting 4 platforms combined with each other by means of a retainer 5 and having guide rods of plate hooks 6 with retainers placed on them the rod of the plate hooks 7 and through guide holes 8, in which the rods of the plate hooks 18 are located, passing from the side of the surgical field into the hooks 9, and on the opposite end having return springs 10 resting on

the supporting platform 11, and the fixing part 2, which is an elastic belt 12, the length of which can be adjusted by the latch of the belt 13, containing the locking bar 14 and the hook 15, which corresponds to the fixing slot 16 on the edge of the corrective platform 4 and allows you to change its diameter depending on the diameter the patient’s head, while the proximal part of the elastic belt 12 is fixed in the fixation slot 17 located on the edge of the supporting platform 3, by means of the bracket 18.

The device operates as follows.

The working part of the device 1 is superimposed on the forehead of the operated. Her fixation is carried out by means of the fixing part 2. In this case, the length of the elastic belt 12 is determined by the diameter of the head and is adjusted by the belt lock 13. The final installation of the working part 1 is carried out by fixing the hook 15 in the fixation slot 16 of the correcting pad 4. An incision is made in anticipation of the mouth above the transition fold from right upper canine to left. The latter is connected to a pre-performed endonasal incision along the bottom of the nasal cavity. The plate hooks 9 are inserted into the surgical wound in the area of the transitional fold of the vestibule of the mouth, the distance between them depending on the anatomical features of the facial skull, which determine the length of the cut and is corrected due to the mutual movement of the supporting 3 and corrective 4 platforms relative to each other and is fixed by means of the latch 5. Return thrust return

springs 10, abutting against the support pads 11 provides a reverse stroke of the rods of the plate hooks 18. In this case, the parallelism and stability of the movement of the rods of the plate hooks 18 is ensured by their movement in the guide holes 8 made in the guide rods of the plate hooks 6, placed on the supporting 3 and corrective 4 platforms. The return stroke of the rods 18 with plate hooks 9 promotes the raising of the upper lip with the skin of the nose, which slide along the inner surface of the plate hooks 9, resulting in a complete exposure of the bone-cartilaginous base of the nose and a constant, smooth pushing and holding of soft tissues of the surgical field. If necessary, additional separation of tissues, stop bleeding, or other concomitant surgery of any surgical manipulation of any of their plate hooks 9 can be temporarily fixed by the rod retainer of the plate hooks 7.
