Description

Tool for tissue extraction and cavity sanitation

The utility model relates to endosurgical instruments, in particular to the group of auxiliary instruments for tissue extraction and cavity sanitation, and can be used for simultaneous aspiration, irrigation and tissue coagulation, while the foaming effect allows you to remove fibrin, blood clots, pus, necrotic tissue from the cavity .

A well-known tool for tissue extraction and cavity sanitation, containing an aspiration-irrigation tip made of two combined tubes connected through an adapter to a valve device (MFS product catalog, Kazan. Mulkova Brusan washer, p. 18).

A disadvantage of the known instrument is its limited functionality, since during an endosurgical operation, in addition to aspiration and irrigation, tissue coagulation is required to stop bleeding, or tissue dissection and hemostasis during laparoscopic interventions.

The purpose of the utility model is to expand the functionality of the instrument for the effective implementation of endosurgical interventions.

This goal is achieved by the fact that in the instrument for tissue extraction and cavity sanitation, containing an aspiration-irrigation tip connected through an adapter to the valve device, the tip is made single-channel in the form of a tube coated with a dielectric, while the working part of the tube is made at an angle of 35-60 ° to the axis of the tool to ensure coagulation or dissection of narrowly limited areas, and hardened by a metal ring, in addition, a dielectric handle is mounted on the tip, on which the plug is fixed,

for connecting to an electric current source electrically connected to the tube.

The proposed utility model is depicted in the drawing, FIG. 1 - general view.

The tool for tissue extraction and cavity sanitation contains an aspiration-irrigation tip 1, which is connected through an adapter 2 to the valve device 3. The tip 1 is made in the form of a single-channel tube 4 coated with a dielectric 5. The working part of the tube 4 is made at an angle of 35-60 ° to the axis tool for coagulation or dissection of narrowly limited areas and hardened by a metal ring 6. A dielectric handle 7 is mounted on the tip 1, on which a plug 8 is fixed for connection to an electric current source (not shown in the drawing cauldron) electrically connected to the tube 4.

A tool for tissue extraction and cavity sanitation works as follows.

When carrying out endosurgical operations, instruments are used that are part of the group of auxiliary instruments, for example, an instrument for tissue extraction and cavity sanitation, with which a biopsy or drainage is performed. After taking a piece of tissue, the bleeding area immediately coagulates, which prevents complication. Liquid aspiration, for example, from the abdominal cavity has both diagnostic and therapeutic value. For example, bile is aspirated through a tip tube, blood clots are washed and the cavity is drained.

The suction and irrigation tip 1 is connected through an adapter 2 to a valve device 3, which is connected by a hose to a source of washing liquid (not shown in the drawing).

The distal end of the suction and irrigation tip 1, the working part of which is made at an angle of 35-60 ° to the axis of the tool and hardened by a metal ring 6, is in contact with a narrowly limited

patch of tissue. Through the valve device 3, connected through the adapter 2 to the single-channel tube 4, the flushing fluid is supplied (the valve handle "on my own" is open). After flushing the cavity, the valve device 3 is closed (the handle of the valve "on itself" is closed).

Then, if necessary, plug 8, electrically connected to the tube 4, is connected to an electric current source (not shown). Tissue is dissected or coagulated with an elliptical ring 6 fixed to the working end of the tube 4.

The advantages of the proposed tool are as follows:

1. The surgeon’s functional capabilities are expanded, providing tissue suction, irrigation and coagulation without changing the instrument, which increases the effectiveness of endosurgical interventions.

2. The tool provides coagulation of a narrowly limited area due to the fact that the working part of the tube is made at an angle of 35-60 ° to the axis of the tool.

3. The elliptical ring protects the dielectric wear at the boundary of the working part of the tool and ensures reliable electrical contact of the tissue with the tube, which is connected to an electric current source.
