RU59957U1 - SURGICAL LIGHT FIXTURE LIGHT - Google Patents

Abstract

Usage: medicine, in particular abdominal surgery. The optical fiber on a surgical retractor for a mini-assistant kit is an organic glass cylinder with dimensions: 120 mm long, 7 mm in diameter. The working end is bent at an angle of 30 g along the direction of the retractor to direct the light beam into the illumination area of the surgical field. The proposed fiber has a large light transmission capacity, has a longer resource of use and reliability, in comparison with analogues of monoglass fiber, and does not change its characteristics during chips. 1 ave., 2 ill.

Description

The utility model relates to medicine, in particular to abdominal surgery, and can be used when performing operations on abdominal organs.

It is known to use mini-assistant kits for performing open laparoscopic operations in abdominal surgery (A. Balalykin, “Endoscopic Abdominal Surgery”, M., 1996, p.6-26; M. M. Prudkov “Minilaparotomy and“ open ” laparoscopy in the treatment of patients with cholelithiasis ", Abstract of dissertation for the degree of Doctor of Medical Sciences, M., 1993, 53 pp .; Frantzaydes K." Laparoscopic and Thoracoscopic Surgery ", St. Petersburg," Nevsky Dialect ", 2000, p. 157-174.). In these sets, the illumination of the surgical field is carried out by a light guide mounted on the blade.

Closest to the proposed one is a surgical retractor-illuminator with a light guide, representing a mono-glass fiber curved in the form of a hook, the transmittance of light of which is 0.7-0.8 (RU No. 94011865/14 IPC A 61 V 17/02, 1996.04.27).

Its disadvantages are the weakness of the fastening of the fiber with the light guide, the fragility of monoglass fiber, as a result, with a long load, chips of monoglass fiber and a decrease in light transmission occur. With the subsequent contact of disinfectant solutions (during sterilization) in the monofilament chips, the latter becomes turbid.

The technical result is an improvement in the illumination of the surgical field and an increase in the resource of use of the fiber.

The specified technical result is achieved by installing an organic glass fiber on a surgical retractor, the light transmittance of which is 0.8-0.95.

The device is illustrated by the following figures: figure 1 shows a General view of the proposed device; figure 2 - the same in comparison with the prototype

on the area and power of lighting.

The light guide is an organic glass cylinder with the dimensions:

120 mm long, 7 mm in diameter. The working end 1 is bent at an angle of 30 ° along the direction of the retractor to direct the light beam into the illumination area of the surgical field. The opposite end 2 of a length of 70 mm is covered with a protective metal sheath for fixing to a surgical retractor and attaching a light guide cable to it.

The proposed device is used as follows: when performing abdominal operations, a minilaparotomy is performed, a mini-assistant ring is installed around the surgical wound, and a surgical retractor with a light guide is fixed on the ring. When performing the surgical scope of the operation, the light guide illuminates the operating field deep in the wound.

Thus, the proposed fiber has a large light transmission. Organic glass has a longer resource of use, less prone to chips and does not change its characteristics when chipped.

Claims (1)

The optical fiber on the surgical retractor as part of a mini-assistant kit containing a cylinder 120 mm long, 7 mm in diameter as a light guide, the working end of which is bent at an angle of 30 ° along the direction of the retractor, characterized in that it is made of organic glass with a light transmittance 0.8-0.95.
