Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surgical instruments, in particular to a lower pharyngeal cavity foreign body removing forceps which helps to quickly remove foreign bodies in the pharyngeal cavity, especially large foreign bodies, and quickly relieve airway obstruction. BACKGROUND

[0002] Airway obstruction refers to ventilation dysfunction caused by diseases inside and outside the respiratory tract. With the glottis as the boundary, respiratory tract obstruction can be divided into upper respiratory tract obstruction and lower respiratory tract obstruction, among which pharyngeal cavity foreign body of upper respiratory tract obstruction is particularly dangerous. The pharyngeal cavity is a funnel-shaped muscular conduit. When the foreign body is descending, it may be stuck in the deep pharyngeal cavity. If it is not treated in time, it may cause respiratory tract foreign body obstruction. In severe cases, acute laryngeal obstruction may occur, suddenly unable to speak, cough or breathe, extremely difficult to breathe, and even life-threatening in severe cases. Rescue must be done in seconds. The common treatment methods for airway obstruction include Heimlich first aid method (abdominal impact method), back patting method, chest impact method, etc., each having a certain range of application. When the above methods are ineffective, professional personnel choose to use special instruments to remove foreign bodies (Kelly forceps, Magilla forceps), etc. Kelly forceps are a commonly used type of hemostatic forceps suitable for large blood vessel control and movement and removal of tissues during surgery. The forceps head is narrow and has insufficient curvature, limiting the removal of foreign bodies, and is suitable for the removal of only a small part of foreign bodies. Magilla forceps often need to straighten the airway, which is generally used for tracheal intubation by anesthesiologists. For non-anesthesia professionals, the efficiency of using the forceps to remove foreign bodies is not high. SUMMARY

[0003] In view of the above problems, the purpose of the present application is to provide a lower pharyngeal cavity foreign body removing forceps which can quickly remove foreign bodies in the pharyngeal cavity and relieve respiratory tract obstruction caused by large foreign bodies.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a lower pharyngeal cavity foreign body removing forceps is designed, which comprises two first foreign body clamps and second foreign body clamps that are hingedly connected to each other, the two ends of the first foreign body clamp are respectively provided with a first long oval holding ring, a first neck portion and a first handle, the two ends of the second foreign body clamp are respectively provided with a second long oval holding ring, a second neck portion and a second handle; the first foreign body clamp and the first neck portion are arc-shaped curved, the second foreign body clamp holding ring and the second neck portion are arc-shaped curved; the outer surface of the first long oval holding ring and the second long oval holding ring is smooth, and the inner surface has teeth, and when occluded, the inner surface is occluded tightly on the outside and has a gap on the inside.

[0005] Preferably, the first foreign body clamp and the first neck portion are arc-shaped curved downward by 60 degrees, and the second foreign body clamp holding ring and the second neck portion are arc-shaped curved downward by 60 degrees.

[0006] Preferably, the first long oval holding ring and the second long oval holding ring are both 2.3 cm x 1.3 cm in length x width.

[0007] Preferably, the first neck and the second neck are curved, and the length of the curve from the starting part of the first neck or the second neck to the head is about 6 cm.

[0008] Preferably, when the first long oval holding ring and the second long oval holding ring are occluded, the outer half of the inner surface is occluded tightly, and the inner half of the inner surface is recessed with a gap.

[0009] Preferably, the first handle and the second handle are each provided with a ring-shaped hand holding part.

[0010] Preferably, the device is used for removing large blockage foreign matter in the pharyngeal cavity in otolaryngology, pediatrics, and emergency department.

[0011] Preferably, the device is made of cold steel or high-speed tool steel.

[0012] Compared with the prior art, the present application has the following beneficial effects: 1. The foreign body forceps of the present application is 60 degrees downwardly curved at the holding ring and the neck, which is suitable for the angle of the pharyngeal cavity, and the long axis of the oral cavity and the long axis of the pharyngeal cavity are close to 90 degrees. When the pharyngeal cavity is examined and the foreign matter is removed, the child often slightly raises his head to reduce the angle. Therefore, the device of the present application simulates the angle of the pharyngeal cavity, which can effectively achieve the purpose of quickly removing the foreign matter along the natural passage of the pharyngeal cavity.

[0013] 2. The length of the curved starting part to the head of the foreign body forceps of the present application is about 6 cm, which is only half of the length of the curved starting part to the head of the conventional laryngeal forceps. The foreign body forceps of the present application is short and small, and the 60-degree curved angle is small, so it can be quickly inserted into the pharyngeal cavity to remove the foreign matter.

[0014] 3. The pharyngeal cavity foreign body forceps of the present application is provided with a long oval holding ring, which is 2.3 cm x 1.3 cm in length x width, which is significantly larger than the holding ring of the oval forceps and the Magilla forceps, which is conducive to stronger holding of the foreign matter and facilitates the removal of the foreign matter.

[0015] 4. The pharyngeal cavity foreign body forceps of the present application is provided with a long oval holding ring, which is smooth on the outside, and has teeth on the inside. The outer half of the inner surface of the holding ring is occluded tightly, which can enhance the holding force, and the inner half of the inner surface of the holding ring is recessed, which can precisely hold the sheet-shaped foreign matter. When the holding ring is occluded, the outer half of the inner surface is occluded tightly, and the inner half of the inner surface has a certain gap, which facilitates the embracing action of large foreign matter and is less likely to slip off.
