Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a low-irritation throat foreign body removal instrument. Background Art

[0002] At present, the treatment of laryngeal foreign bodies usually adopts direct laryngoscopy or indirect laryngoscopy to directly remove laryngeal foreign bodies with laryngeal foreign body forceps. However, when encountering sensitive throats, stenotic throats, and other difficult-to-remove foreign bodies in the hypopharynx, piriform sinus, etc., which makes it difficult to quickly remove foreign bodies under laryngoscopy, tracheotomy can be performed first, and after the dyspnea is relieved, general anesthesia can be applied, and then the foreign bodies can be removed under direct laryngoscopy. At present, the most commonly used foreign body forceps in clinical practice are rat bite forceps, which are mutually interlocking forceps heads, and the usage rate in my country is more than 40%. Mutually interlocking forceps heads are very suitable for clamping strip-shaped, rod-shaped or sheet-shaped foreign bodies, but it is difficult to firmly clamp the most common spherical foreign bodies such as peanuts and nuts in clinical practice. It is very easy to cause spherical or round foreign bodies to slip during the clamping process, causing secondary injuries or even suffocation. For slightly larger and smooth spherical foreign bodies, such as marbles, it is even impossible to clamp them at all. This will lead to the removal of foreign bodies, and the patient's airway obstruction cannot be relieved for a long time, and in severe cases, it may even endanger the patient's life. Many clinical patients have foreign bodies in their throats that are soft and easily deformed or broken into small pieces, such as jelly-like objects such as jelly and gel. It is extremely difficult to handle such foreign bodies with interlocking foreign body forceps. Due to the large bite forceps head, the doctor's slight movement can cause the foreign body to break into small pieces and fall off, and it is very easy to adhere to the patient's laryngeal mucosa and glottis, posing a great danger to the patient. Some foreign bodies are closely attached to the laryngeal mucosa or vocal cords. When clamping foreign bodies, the interlocking forceps heads can easily injure the mucosa and other surrounding tissues, causing unnecessary bleeding, laryngeal edema and other consequences. Some large foreign bodies have rough or even protruding edges. In the absence of a protective cover, the interlocking forceps heads can easily scratch the mucosa and other surrounding tissues when removing foreign bodies.

[0003] For example, in a Chinese patent with patent number CN 210250024 U, a throat foreign body forceps is disclosed, comprising two matching pairs of forceps bodies, the two forceps bodies are hinged in the middle, the forceps bodies are of a hollow structure, the tail of the forceps bodies are sleeved on the head of the handle, the forceps bodies are slidably connected to the handle, a spring is arranged between the forceps bodies and the handle, and a clamping part is arranged on the head of the forceps bodies; the clamping part is a hemispherical surface surrounded by a plurality of clamping arms, the clamping arm comprises a deformation part and a movable part, the tail of the deformation part is connected to the head of the forceps body, the head of the deformation part is fixedly connected to the head of the movable part, the tail of the movable part extends to the inside of the forceps body, the tail of the movable part is connected to the head of the handle through a transmission part, and the movable part is located on the side of the deformation part away from the center of the sphere.

[0004] However, the throat foreign body forceps in the above patent have the following defects:

[0005] The entire forceps body is in the shape of scissors, which cannot achieve a bending effect, and the angle is fixed. When used by doctors, the bending degree cannot be adjusted, resulting in the inability to adjust the entry position and entry direction during actual operation, causing great pain to the patient. Summary of the invention

[0006] The utility model aims to provide a low-irritation throat foreign body removal instrument, which can be bent appropriately to facilitate adjustment for removing foreign bodies with irregular shapes, can maintain the integrity of foreign bodies, reduce human body harm, and has different specifications to suit adults and children.

[0007] The technical idea of ​​the utility model is:

[0008] A pull-out control component is used to control the opening and closing of the micro-opening and closing forceps, so that the doctor can operate the micro-opening and closing forceps with one hand to remove foreign objects from the patient's throat, and the stabilizing component between the pull-out control component and the micro-opening and closing forceps is set to a structure that can be flexibly bent according to actual usage.

[0009] A copper tube is set outside the patient's mouth, and the copper tube does not extend into the patient's mouth to ensure the stability of the bendable structure. The bendable structure only bends moderately inside the patient's mouth. This foreign body forceps is mainly used for tiny foreign bodies with force points, such as fine nails, fish bones, chicken bones, etc. Because the jaws are opened relatively small, it is ineffective for foreign bodies such as glass beads that have no force points.

[0010] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0011] A low-irritation throat foreign body removal instrument comprises a micro-opening and closing forceps, and also comprises a fixing part, which is arranged at the rear end of the micro-opening and closing forceps and is used to control the opening and closing of the micro-opening and closing forceps;

[0012] Pulling part; used in conjunction with the fixing part to keep the micro opening and closing forceps stable;

[0013] The bending part is arranged between the fixing part and the opening and closing forceps, and is used for adjusting the path of the micro opening and closing forceps entering the throat.

[0014] In order to facilitate the doctor's operation, a further optimization scheme of the utility model is: the fixing part includes a pull cable, a conical cylinder, a circular plate and a locking block, the front end of the pull cable is connected to the micro-opening and closing forceps, and the pull cable passes through the conical cylinder and the circular plate, and the rear end is connected to the locking block.

[0015] In order to adjust the curvature of the cable and facilitate the micro-opening and closing forceps to enter the patient's throat, a further optimization scheme of the utility model is: the bending part includes a plastic sleeve and a copper tube, the outer sleeve of the cable located between the conical cylinder and the micro-opening and closing forceps is provided with a plastic sleeve, and the copper tube is fixedly connected to the front end of the conical cylinder.

[0016] Furthermore, the pulling part includes a fixed rod, a fixed ring and a slip ring. The fixed rod is provided with a sliding groove, and the outer periphery of the fixed rod is slidably connected with a slip ring. The slip ring is provided with a snap-fitting groove that matches the snap-fitting block. The snap-fitting block is slidably connected with the sliding groove, and a fixed ring is provided at the rear end of the fixed rod.

[0017] In particular, pull rings and arc-shaped handles are symmetrically arranged at both ends of the slip ring.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] (1) The copper tube is only outside the patient's mouth because it has good ductility, moderate hardness, and can be bent moderately. At the same time, the rear end of the copper tube is fixedly connected to the conical barrel to ensure that the plastic sleeve near the end of the conical barrel will not sag or bend too much, thus ensuring stability.

[0020] (2) The plastic sleeve and micro-opening and closing forceps are inserted into the patient's mouth. The doctor can flexibly adjust the curvature of the plastic sleeve to control the position of the micro-opening and closing forceps and the path of the micro-opening and closing forceps entering the patient's throat. The plastic sleeve can also be kept horizontal. When using it, the doctor can flexibly choose so that the patient will not feel too much discomfort and it is more convenient to remove foreign objects in the throat.
