Curved hemostatic forceps for conveniently placing intrathoracic drain

Abstract

The invention discloses a curved hemostatic forceps for conveniently placing an intrathoracic drain. The curved hemostatic forceps conveniently guides the intrathoracic drain into the thoracic cavitysmoothly, avoids excessive force or repeatedly using the hemostatic forceps for exploration, alleviates the sufferings of patients, and improves operation efficiency. The hemostatic forceps consists of grip rings, a buckle, a forceps handle, an axial ring and forceps leaves. Alveolus bed surfaces of two forceps leaves are provided with symmetrical concave surfaces, the concave surfaces are of semiellipse shape along cross sections of the forceps leaves, the concave surfaces of the two forceps leaves form a tubular structure with the cross section of oval shape when the hemostatic forceps is closed, and a tubular head is of conical shape and points at the front end of the forceps leaves; in such a way, a clamped cylindrical intrathoracic drain can slightly deform, which is favorable for exact clamping. Insection at other part of the alveolus bed is transverse insection, and insection at the concave surfaces part is vertical insection along vertical axis of the forceps leaves, which caneffectively clamp the intrathoracic drain tightly, and does not coarsen and damage the smooth surface of the intrathoracic drain. The head of the forceps can support the chest-wall muscular layer andparietal pleura, guide the orifice of the intrathoracid drain clamped by the forceps leaves into the thoracic cavity smoothly, and then the forceps is loosened, and leaves the thoracic cavity. The conical head part of the tubular structure can exactly clamp intrathoracic drains of different diameters, and avoid bringing out the intrathoracic drains when the hemostatic forceps is removed.

Description

Technical field [0001] The invention belongs to the field of medical equipment, and designs a curved blood vessel clamp which is convenient for placing a chest drainage tube. Background technique [0002] Closed thoracic drainage is the most common surgical operation in thoracic surgery. Curved vascular clamps are usually used to clamp the head of the drainage tube and introduce it into the chest cavity. Under normal circumstances, the vascular clamp is easy to enter during exploration, but it is not easy to enter after clamping the drainage tube; or the tip of the forceps can enter smoothly, but the drainage tube orifice is often stuck in the chest wall tissue. This is mainly because the entrance to the thoracic cavity was initially formed after the vascular clamp was separated and broken through. The parietal tissue is elastic and recovers quickly after being expanded. The drainage tube orifice is relatively large, especially after the tube orifice is flattened by the vascular ...

Problems solved by technology

However, these designs also have some disadvantages: first, the metal nozzle or metal guiding stylet has the potential risk of damaging tissues and organs in the chest cavity after entering the chest cavity; second, the drainage tube is a disposable consumable , these designs increase the comple...
