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
Affiliated technical field
The invention belongs to medical instruments field, design a kind of curved hemostatic forceps of being convenient to place intrathoracic drain.
Background technology
Closed drainage of thoracic cavity operation is the modal operation technique of thoracic surgery, uses curved hemostatic forceps usually, the drainage tube head-clamp is lived the back import the thoracic cavity.Generally, be easy to when vascular forceps is detected enter, but be difficult for entering behind the clamp drainage tube; Perhaps the pliers head can enter smoothly, but the drain mouth of pipe often is stuck in the thoracic wall tissue.This mainly is because the thoracic cavity inlet is formed by vascular forceps separation, breakthrough back at first, the elasticity of parietal layer tissue is big, very fast recovery after strutting, the drain mouth of pipe is relatively large, particularly the mouth of pipe by the blood vessel clamp flat after, transverse diameter further increases, and is difficult for entering the thoracic cavity with the very thin vascular forceps of head by cut.As force one's way through the barrier, patient feels very pain, and operation technique is produced fear, is unfavorable for partner treatment.
In recent years, researcher had designed some apparatuses, for example the oral portion of drainage tube was designed to metal material, perhaps designed a metal guide tube core, and purpose all is will be convenient to the drain mouth of pipe to enter the thoracic cavity smoothly.But these designs also exist some shortcomings: the first, and the mouth of pipe of metal material or metal guide tube core all have the risk of potential damage thoracic cavity inner tissue organ after entering the thoracic cavity; The second, drainage tube is disposable consumptive material, and these designs have increased the complexity of drainage tube, have increased cost, causes medical expense and patient's burden, and too much adnexa has caused very big waste; The 3rd, particularly the drainage tube of the metal material mouth of pipe is present in the regular period in the thoracic cavity, can disturb diagnosis and treatment.Therefore, ideal solution should not make drainage tube complicated, and will address beyond drainage tube.
Summary of the invention
The purpose of this invention is to provide the curved hemostatic forceps that a kind of convenient guiding intrathoracic drain enters the thoracic cavity smoothly, to overcome the deficiencies in the prior art.
The technical solution adopted in the present invention is: vascular forceps is made up of handle ring, snap close, pincers handle, joint, pincers leaf.The teeth groove bed surface of two pincers leaves, the symmetric concave surface in position is arranged, be positioned at after the pincers leaf head, concave surface is a half elliptic along the cross section of pincers leaf, and during closed vascular forceps, it is oval-shaped tubular structure that the concave surface of two pincers leaves forms cross sections, tubular head is a taper, point to the front end of pincers leaf, can make the cylindric drainage tube generation slight deformation of being pressed from both sides like this, it is definite to help clamping.The groove of tooth socket bed remainder is a band, and the groove of concave part is along the pincers leaf longitudinal axis perpendicular stricture of vagina out of shape, can effectively clip drainage tube, again can be with the smooth surface hacking of drainage tube, and damage drainage tube surface.Binding clip can strut thoracic wall flesh layer and parietal pleura, and guiding is entered the thoracic cavity smoothly by the drain mouth of pipe of pincers leaf clamping, unclamps pliers then, withdraws from the thoracic cavity.The cone head of tubular structure can satisfy the definite clamping to the drainage tube of different-diameter, also can avoid drainage tube is taken out of when withdrawing from vascular forceps simultaneously.
The invention has the beneficial effects as follows, can quickly and easily drainage tube be inserted the thoracic cavity, be applicable to the placement peritoneal cavity drainage tube too, avoid exerting oneself excessive or use vascular forceps to detect repeatedly, alleviate patient's misery, improve operating efficiency.
Description of drawings
Fig. 1 is the vascular forceps overall schematic that the present invention narrates: handle ring (1), snap close (2), pincers handle (3), joint (4), pincers leaf (5), tooth socket bed (6), concave surface (7)
Fig. 2 be the vascular forceps narrated of the present invention and common vascular forceps side schematic view relatively
Fig. 3 be the vascular forceps narrated of the present invention and common vascular forceps clamping intrathoracic drain side schematic view relatively
The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, and in conjunction with the accompanying drawings, this programme is set forth below by a specific embodiment.
As shown in Figure 1, the vascular forceps narrated of the present invention is made up of handle ring (1), snap close (2), pincers handle (3), joint (4), pincers leaves (5).Tooth socket bed (6) face at two pincers leaves has the symmetric concave surface in position (7), and concave surface is a half elliptic along the cross section of pincers leaf.The groove of tooth socket bed concave part is that the groove of remainder is a band along the pincers leaf longitudinal axis perpendicular stricture of vagina out of shape.
As Fig. 2, shown in Figure 3, a figure left side is common vascular forceps, the vascular forceps of being convenient to place intrathoracic drain that the right side is narrated for the present invention.When the vascular forceps on the figure right side was closed, it was oval-shaped tubular structure that the concave surface of two pincers leaves forms cross sections, and tubular head is a taper, points to the front end that clamps leaf, can make the cylindric drainage tube (8) that is pressed from both sides that slight deformation takes place like this, and it is definite to help clamping.The perpendicular stricture of vagina of concave part can effectively clip drainage tube, again can be with the smooth surface hacking of drainage tube, and damage drainage tube surface.Binding clip can strut thoracic wall flesh layer and parietal pleura, and guiding is entered the thoracic cavity smoothly by the drain mouth of pipe of pincers leaf clamping, unclamps pliers then, withdraws from the thoracic cavity.The cone head of tubular structure can satisfy the definite clamping to the drainage tube of different-diameter, also can avoid drainage tube is taken out of when withdrawing from vascular forceps simultaneously.
