Description

Adjustable gripping type percutaneous dilatation tracheotomy forceps

Technical Field

The utility model relates to the field of medical instruments, in particular to an adjustable holding type percutaneous dilation tracheotomy forceps.

Background

The percutaneous tracheotomy technology can be used for quickly establishing an artificial airway for a critically ill patient, and saving lives. At present, the percutaneous tracheotomy technique is mainly a tracheotomy technique guided by a guide wire, and a core tool of the percutaneous tracheotomy technique is a tracheal dilating forceps. Guided by guide wires, expanded layer by the expander and then expanded by using percutaneous tracheotomy expansion forceps.

It is often encountered in clinical practice that the tracheal cannula has more gaps after being placed in due to excessive tissue expansion of the tracheotomy dilating forceps, or the tracheal cannula cannot be smoothly placed in due to insufficient tissue expansion of the tracheotomy dilating forceps, and needs to be repeatedly dilated. The tracheal cannula is divided into a plurality of types from adults to children according to the size of the inner diameter, different expansion degrees are needed, when the tracheal cannula is expanded by using the opening forceps, the tracheal cannula needs to be fixed by hands of an operator, and the expansion tension degree of the expansion forceps is controlled according to the inner diameter of the trachea; the separated expansion mode is laborious to use, and the arms can generate fatigue after a long time, so that the expanded trachea can be easily displaced, and even the surrounding tissues and blood vessels can be damaged; meanwhile, the expansion of part of the expansion forceps is realized only by operating the distraction forceps arms with two hands because the force is reversed, and the operation view is not clear easily because the operation cannot be performed with one hand and the number of the hands is large; in addition, because the expansion forceps are not provided with a control limit, and adopt a separated expansion mode, when the expansion forceps are expanded, if an operator excessively exerts force, the tracheal space is excessively torn, even peripheral blood vessels are injured, so that heavy bleeding is caused, and the operation risk is increased.

The adjustable holding type percutaneous dilatation tracheotomy forceps of the utility model has the advantages that due to the action of the spring plectrum 50, the elbow part is always in a close fit state, a guide wire which is guided and sent in through a trocar is penetrated through a guide wire inlet 11, is sent in along a circular channel which is formed by enclosing a guide wire groove 12, then is sent out from a guide wire outlet which is formed by a notch 13, is slowly guided to be sent into a tracheotomy along the guide wire through a tracheotomy dilating forceps, the tracheotomy dilating forceps are held by one hand, a closing holding part 30 is grasped to lead the closing holding part to draw close inwards, the elbow part is slowly dilated, the buckling teeth of the first forceps body 100 and the second forceps body 200 relatively move, and the clicking sound generated by the collision of the anti-skidding teeth of the buckling teeth can be heard by each forward gear, can realize listening to sound and judge the gear, also can judge the expansion gear through observing measurement sign 52, cut the pipe model according to target trachea, fully expand to required width. The anti-slip teeth 61 enable the buckling rack to be fixed, and the controllable and adjustable effect without hand fixing is achieved.

Example two

Referring to fig. 5, the present embodiment is an improvement on the first embodiment, and is different from the first embodiment in that the end of the elbow 10 is provided with a tip 14, so that the end of each forceps body can form one point on the skin of the human body, and two points can be formed by two forceps bodies. Thereby can open the model according to the trachea of different models, expand elbow portion to suitable size before opening the skin, the tip of elbow portion is infected with behind the beautiful blue of trachea front neck skin and does and open the body surface and fix a position. The pointed end 14 is located at the end of the guide wire groove 12, thereby enlarging the guide wire inlet 11 formed by the guide wire groove, and further facilitating the guide wire to enter the circular channel.

EXAMPLE III

Referring to fig. 6, the present embodiment is an improvement on the basis of the first or second embodiment, and is different from the first or second embodiment in that the present embodiment further includes a nesting sleeve which is sleeved at the end portions of the bent portions of the first and second forceps bodies, and the nesting sleeve encloses the first sleeve cap, the second sleeve cap, and a state rope which is connected between the first sleeve cap and the second sleeve cap; the tops of the first sleeve cap 71 and the second sleeve cap 72 are sharp ends. The expansion degree of the elbow part 10 is limited by the length of the state rope 73, the tops of the first sleeve cap 71 and the second sleeve cap 72 are tip heads, so that the elbow part can be expanded to a proper size before skin incision according to different types of tracheotomy types, and the tip heads of the nesting sleeves 70 are stained with blue to perform body surface incision positioning on the skin of the front neck of a trachea.

Example four

The difference between this embodiment and the first, second, and third embodiments is that in this embodiment, the first forceps body and the second forceps body are hinged after being intersected with each other, and the shape is like a scissors, in this embodiment, the expansion of the elbow portion is realized by expanding the holding portion, the spring pulling piece is used for tensioning the first forceps body and the second forceps body, when the expansion is started, the end moving direction of the spring pulling piece is opposite to that of the first embodiment, and the moving direction of the buckle rack is also opposite to that of the first embodiment, but the basic design idea and the working principle are the same, and are not described again.
