RU193410U1 - Retractor for surgical interventions on the abdominal organs from mini access - Google Patents

Abstract

A useful retractor model for surgical interventions on abdominal organs from mini access refers to medicine, surgical instruments and can be used in various fields of surgery in traditional and minimally invasive cavity operations. The retractor includes a handle with holes, the working part in the form of a scapula. A soft thin two-wire electric wire is fixed on the handle with holes with brackets, at one end of which an LED strip is fixed in a sealed silicone capsule and is located on the front surface of the blade, and a plug is located on the second end of the soft thin two-wire electric wire. The use of the proposed technical solution will allow, in comparison with the known technical solutions, to improve the illumination of hard-to-reach, sloping areas of the surgical wound during surgery. The utility model is aimed at improving the conditions for surgical intervention.

Description

The utility model relates to medicine, to surgical instruments and can be used in various fields of surgery in traditional and minimally invasive abdominal operations.

Known surgical retractor-illuminator (RU No. 142738, publ. 07/10/2014), consisting of a hook, on which, using a bracket, a curved fiber with a monofilament lead bundle is fixed, the curved fiber is made with a length equal to 0.3-0.5 of the length of the curved part of the blade of the hook, and repeats its shape, while the end of the curved fiber is made flattened.

Known surgical retractor-illuminator (RU No. 116762, publ. 10.06.2012), consisting of a hook, on which with the help of an arm a curved light guide with a monofilament fiber supply cable and a working part in the form of a scapula is fixed. Holes are made on the handle.

The disadvantages of the known technical solutions are bright lighting in a small, strictly fixed area under the light guide due to the small area of the light spot, and therefore there is not enough uniform illumination of the surgical wound. A fiber optic guide with a monofilament fiber harness limits the surgeon's actions during surgery.

The objective of the utility model is to eliminate the above disadvantages of known technical solutions.

The problem is solved using the proposed retractor for surgical interventions on the abdominal organs from mini access, including a handle with holes, a working part in the form of a scapula, moreover, a soft thin two-wire electric wire is fixed to the handle with holes with brackets, one end of which is fixed LED strip in a sealed silicone capsule and located on the front surface of the blade, and at the second end of the soft thin two-wire electrical wire is a plug.

The technical result consists in improving the illumination of hard-to-reach, sloping areas of the surgical wound during surgery.

The utility model is illustrated in the drawing.

FIG. 1 is a general view of a retractor for surgical interventions on the abdominal organs from mini access.

A retractor for surgical interventions on the abdominal organs from mini access includes: a handle 1 with holes 2, a working surface in the form of a scapula 3, LED strip 4, in a silicone capsule, a soft thin two-wire electric wire 5, plug 6, staples 7 for securing the wire.

A retractor for surgical interventions on the abdominal organs from “mini access” works as follows: after performing operative access, plug 6 located on the end of a soft thin two-wire electric wire 5, fixed with brackets 7 on the handle 1 is connected to a current source, a scapula is inserted into the wound 3, on the front surface of which is located the LED strip 4 in a silicone capsule and form the operating space. If necessary, during surgery, it is possible to change the position of the handle 1 on the ring of the expander (not shown in Fig.) Using holes 2, as a result of which the position of the blade 3 with the LED strip 4 changes, thereby adjusting the necessary amount of operative access. The spectrum of radiation favorable for the human eye from the LED strip 4 does not tire the surgeon, the silicone capsule is highly resistant to mechanical stress (shock) and cuts from the side of the surgical instrument. The small dimensions of the retractor do not clutter the surgical field; they are easily cleaned without being removed from the surgical zone. After surgery, the retractor is removed from the wound. Using the proposed retractor for surgical interventions on the abdominal organs from a mini-access, a wide field of uniform scattered light is achieved, which is regulated by the brightness of the glow. The light source is the LED matrix itself, fiber optics are not required. Placing a light source with a large glow area on the surface of the blade 3, placed directly in the area of active operational manipulation, allows to obtain a sufficient level of illumination, regardless of the position of the blade 3. A soft thin two-wire electric wire does not hamper the surgeon, unlike lamps based on optical fiber. It does not require special sterilization procedures. It has a standardized connector for connecting. All electrical contacts are insulated, which eliminates the possibility of electrical injury.

Thus, the use of the proposed technical solution will allow, in comparison with the known technical solutions, to improve the illumination of hard-to-reach, sloping areas of the surgical wound during surgery. The utility model is aimed at improving the conditions for surgical intervention.
