Abstract
The invention relates to the improvement of dilating forceps used in percutaneous dilatation tracheotomy. A dilating forceps used in tracheotomy comprises a nippling lever composed of elbow and handle, a mechanism used for controlling the opening width of the elbow, and thread guide groove on the elbow. Under the action of the mechanism for controlling the opening width of the elbow, formed tracheostoma will not be two large, which can not only prevent wound caused by over sized tracheostoma, but also is in favor of rapid formation of tracheostoma and shortens operation time.
Description
Technical field
The present invention relates to the apparatus that surgical operation uses, more particularly, relate to the stretching pliers that is used for percutaneous expansion tracheotomy and improve.
Background technology
The percutaneous tracheotomy grew up in nineteen fifty-three, but because apparatus at that time is difficult to use, and important structure causes death and few people's application around repeatedly puncturing trachea.Through a lot of scholars' effort, invented new apparatus, since 1985, the percutaneous tracheotomy just was applied to complication and the danger that clinical, new apparatus greatly reduces tracheotomy.Because this apparatus is the different tissue expanders of a plurality of diameters, begins to expand the throat tissue successively from ting model, it is time-consuming longer to finish the expansion incision of trachea.For solve the problem that prior art exists, in recent years, people have invented the elbow stretching pliers of single bore, just the tracheostoma expansion is once finished, and shortened operating time.Though existing elbow stretching pliers head is provided with the seal wire groove that holds seal wire, also can insert the seal wire groove to seal wire in actual mechanical process, and elbow stretching pliers head can successfully stretch into trachea along seal wire.But the seal wire groove on the existing elbow stretching pliers is crooked, and crooked seal wire slot length long (above 25 millimeters), and the case of bending of seal wire is uncertain, executes the patient to be difficult to fast seal wire be inserted in the crooked seal wire groove when operation; In addition, existing elbow stretching pliers only can resemble the head that pins pliers the vascular forceps, after the elbow stretching pliers struts trachea, execute the degree of strutting of the strength control elbow stretching pliers that the patient can only armrest refers to, this control action tends to influence executes concentrating of patient's attention, even might influence the operation of next step operation.
Summary of the invention
At the deficiencies in the prior art, the purpose of this invention is to provide a kind of stretching pliers that is used for bronchotomu, it not only can be inserted seal wire in the seal wire groove easily, but also can lock open pliers head.
The object of the present invention is achieved like this: a kind of stretching pliers that is used for bronchotomu, comprise 2 claw beams that connect by pivot pin, claw beam is made of pliers elbow and pliers handle, and the mechanism of control pliers elbow opening width is arranged on the claw beam, and the pliers elbow has the seal wire groove.
On the basis of technique scheme, the present invention also has following further scheme:
The mechanism of described control pliers elbow opening width is made of left sleeve pipe, right sleeve pipe, positive stop strip and locking mechanism; Left side sleeve pipe and right sleeve pipe kink respectively have spring between 2 claw beams on 2 claw beams; Left side sleeve pipe and right sleeve pipe constitute spacing syndeton by positive stop strip.
Seal wire slot length on the pliers elbow is 2 millimeters-12 millimeters.
On the described pliers elbow postive stop baffle is arranged.
There is the groove of running through described seal wire groove top.
Described claw beam is provided with light fixture.
Described pliers elbow end has the mouth of attraction, attracts a mouthful connection suction pump.
Advantage of the present invention is as follows:
Because, claw beam is provided with the mechanism of control pliers elbow opening width, so and the pliers elbow has the seal wire groove., execute the patient in the process of implementing operation, can entangle seal wire, allow the pliers elbow enter patient's trachea along seal wire by the seal wire groove on the pliers elbow, when after the pliers elbow enters patient's trachea, opening, the mechanism of control pliers elbow opening width can control open pliers elbow, thereby the finger of executing the patient is loosened, and concentrates one's energy to carry out next step operation; Because mechanism's effect of control pliers elbow opening width, the tracheostoma that forms can be not excessive. not only can prevent the excessive wound that causes of tracheostoma, and help forming rapidly tracheostoma, shortened operating time greatly. in addition, the present invention also helps the percutaneous tracheotomy operant level that generally improves the doctor.
The present invention takes to also have following advantage behind the further step:
The mechanism of described control pliers elbow opening width is made of left sleeve pipe, right sleeve pipe, positive stop strip and locking mechanism; Left side sleeve pipe and right sleeve pipe kink respectively have spring between 2 claw beams on 2 claw beams; When left side sleeve pipe and right sleeve pipe constitute spacing syndeton by positive stop strip, execute the patient and only need unclamp the pliers handle, the pliers elbow can open according to the opening width that sets in advance under the effect of spring.
When the seal wire slot length on the pliers elbow is 2 millimeters-12 millimeters, is easy to coincide owing to the seal wire slot length is short, and entangles seal wire with seal wire.
When there is the groove of running through described seal wire groove top, can make seal wire wide-angle enter the pliers elbow.
When on the described pliers elbow postive stop baffle being arranged, can prevent that pliers from excessively going deep into trachea and damaging tracheal tissue.
When described claw beam is provided with light fixture, can remedy the illumination deficiency of shadowless lamp.
Described pliers elbow end has the mouth of attraction, when attracting mouth to connect suction pump, can absorb the blood at operative incision place easily.
