RU190568U1 - Retractor for surgery in the abdominal cavity with automated formation of the configuration of the surgical intervention area - Google Patents

Abstract

Essence: the retractor is a structure consisting of 4 working modules, each of which consists of a rack, a lock mounted on a rack, a working part made in the form of a segmented assembled rack, Cremal, coupled with a controlled electric drive, also equipped with a handle for manually actuating the working part, load sensing system on the working part of the product, hook to grip and hold the edges of the wound connected to the working part by the method of ball fastening and external unit control installed on the operating table. Technical result: an increase in the sector of access to the surgical intervention area, a decrease in the number of assistants during operations, optimization of the load distribution on the wound edges, as a result, minimization of uncontrolled injury to biological tissues, reduction in the configuration time of the operating area configuration, increased efficiency of operations as such. 2 Il.

Description

The utility model (hereinafter referred to as the product) relates to medicine, in particular, to the repressive surgical instruments used in surgical operations in the abdominal cavity.

The closest to the claimed utility model of the retractor is a structure mounted to the operating table, consisting of a vertical stand, a horizontal console, a screw with a handle, which is the working part of the product, and a hook for gripping the edges of the wound (RF Patent for useful model No. 122275 from 27.06. 2012, authors: Balandina, IA, Artemov, A.O., Pastukhov, AD).

Disadvantages: the screw adjusting the position of the pushing hooks, which is the working part of the product, is manually positioned during the operation (diluting the wound edges) manually, which in turn complicates mounting the product on the operating table and, as a result, increases the duration of the configuration of the operating area. In addition, during the adjustment of the surgical field, the load on the wound edges is evaluated only visually, which can lead to excessive load and, as a result, uncontrolled injury to biological tissues in the hook setting areas.

The technical result: an increase in the sector of access to the surgical intervention area, a reduction in the number of assistants during operations, optimizing the distribution of load on the wound edges, as a result, minimizing uncontrolled injury to biological tissues, reducing the configuration time of the operating area, improving the efficiency of operations as such.

This result is achieved by automating the process of diluting the wound edges to create the necessary configuration of the operating area for surgical intervention. Automation is achieved by an integrated into the product design system, controlled from an external electric drive control unit that is fixed on the operating table (outside the operating area), which in turn drives the working part of the product. Diagram of the product, mounted on the operating table, shown in the figure (figure 1). The product consists of 4 working modules and an external control unit. For the operation can be used from 2 to 4 working modules to choose from. In addition, to optimize the setting of the operating zone, each working module supports several tension modes, as a result of which the product supports a wide range of operating zone configurations. Monitoring of the load on biological tissue, to prevent unintentional rupture, is carried out using a sensor system integrated into each working module, which record the change in load on the working part by changing the power consumption of stepper motors and the load placed on each working module between the working part and the fixed rack. . The data coming from this system is processed in the control unit, as a result, in accordance with the algorithm developed based on the analysis of the physical properties of biological tissues, the load on the working part of the product, on which hooks are installed to capture and hold wound edges, is adjusted, and the distribution of biological tissue is optimized accordingly .

General view of the working module of the product is shown in the figure (figure 2). In the carriage (1) there is a kinematic pair mating the working part, made in the form of a segmetrically assembled toothed rack (2) with a hook fixed on it to grip and hold the edges of the wound (3) and cremallera with an electric drive fixed on its axis (4). In addition, for emergency actions, the rack and bottom are also equipped with a manual drive (5). A strain gauge for load analysis (6) is placed between the gun carriage of the mounting stand (7) and the carriage (1).

This utility model will reduce the number of assistants during surgical interventions, reduce the amount of time required to adjust the operating area, facilitate the adjustment of its geometry, reduce the number of unintended critical situations associated with uncontrolled extraction of hooks from the wound cavity a, as well as uncontrollable injury of biotissue with pushes and as a result, to increase the efficiency and safety of operations in the abdominal cavity.
