A needle device for the treatment of diseases and injuries of abdominal organs (the trocar Sabirova) relates to medical instruments used for diagnosis and treatment of injuries and diseases of the chest, abdomen and bladder, etc.

Analogs of the invention

In medical practice in the present period trocars are used in different forms: abdominal trocar, the trocar universal, intercostal trocar, trocar-catheter, trocar to puncture, the trocar Kozlova, etc trocars valve with their variations and valveless, with conical and pyramidal stiletto-obturator.

Criticism analogues

Used until this time the trocars may be used for introduction in the cavity of the human body the tools with tubes and valves, pneumatic cylinders exhaust (inboard) from the side surface obliquely or perpendicularly, which is the Foley catheter, the light guides. Unable to lock solid object (a stone, a fragment) in the cavity of the bladder and not only retrieve it by opening the valves of the trocar and capture a biopsy, coagulation under ultrasound control.

The technique of introduction

The method of implementation of the invention, similar to the practice of the trocars.

The distinguishing feature of the proposed version yavl�is the availability of the disclosure the casing throughout by compression of the fingers of the spikes of the rail, circle, divided by diameter, with excision of a segment of a circle to ensure the mobility of the half.

The features distinguishing the invention from the prototype

1. The presence of the possibility of introducing into the cavity of the human body apparatus and appliances for the diagnosis and treatment of injuries and diseases that are impossible when using all available trocars.

2. Introduced the Foley catheter using the proposed trocar can reliably stop the bleeding from the thoracic and abdominal wall by compression inside a bloated balloon and removing of blood and effusion and subsequent control of completeness of hemostasis.

3. The trocar can be inserted through the wound channel without additional injury, to enlarge the wound for insertion of Foley catheter, etc. of instruments (optical waveguide and the electrode) and reliably to control ongoing bleeding and thereby strictly to determine the indications for the operation.

4. Provides visual and groping to diagnose bladder stone and attempt to hold the capture and removal of the stone doors.

5. The presence of a lock plate (coil spring) for fixing the degree of opening of the casing allows for additional manipulation.

Description of the invention.

A needle device for the diagnosis and treatment of diseases and injuries of abdominal organs consists of a handle and two polutropos, obra�following the stylet trocar (figure 1, 2).

The handle of the trocar is a movably by means of the lock (Fig. 3, 4) two semicircles up to 4 mm thick with excision of a segment for opening the flaps of the stylet with a hole in the center equal to the diameter of the stylet (figure 3, 4), the edges of the bottom surface of which are welded two polutrube (figure 2), forming a tube of the stylet is in the closed state (Fig. 1), and on the upper surface of the semicircle is mounted a valve for closing the openings of the stiletto after removal of the obturator (Fig. 5) and the side with two lugs, which has a retainer plate for retaining the opened state of the trocar. Through the holes in the center of the semicircle is inserted obturator (Fig. 5), which occupies the lumen of the stylet trocar with a protruding pyramid bore the end for safe puncture of the abdominal and other body cavities. Removing the obturator is disclosed sash finger pressure on the lugs of the rim of the circle and insert into the cavity of the bladder, a Foley catheter, cystoscope, fiber, biopsy forceps, coagulators and tools.
