[0020] The technical scheme provided by each embodiment of the utility model will be described in detail below in combination with the drawings.

[0021] The utility model embodiment provides a kind of cricoarytenoid joint reduction forceps, including for clinical cricoarytenoid joint reduction treatment cricoarytenoid joint reduction forceps 1, the cricoarytenoid joint reduction forceps 1 includes main handle 11, from handle 12, main pull rod 13, from pull rod 14, main clamp bar 15, from clamp bar 16, main clamp 17 and from clamp 18, the main handle 11 and from handle 12 are symmetrically arranged and both ends are rotationally connected by pivot, the main pull rod 13 is arranged at the end of main handle 11, the from pull rod 14 is arranged at the end of from handle 12, the main clamp bar 15 is arranged at the end of main pull rod 13, the from clamp bar 16 is arranged at the end of from pull rod 14, the main clamp 17 is arranged at the end of main pull rod 13, the from clamp 18 is arranged at the end of from pull rod 14, the main clamp 17 and from clamp 18 are oppositely arranged and are both oval shape;

[0022] The device provides a better view for surgery by pulling or adjusting the position of cricoarytenoid joint and its surrounding tissues, enables the surgeon to observe the lesion site more clearly, accurately performs surgical operation, reduces damage to the surrounding normal tissues, is simple to use, easy to operate, safe and reliable, prevents gauze or cotton from falling off and missing in the oral cavity during operation, avoids too sharp end of forceps from damaging mucosa or aggravating cricoarytenoid dislocation, increases patient's comfortable experience and reduces the psychological burden of operator.

[0023] In the further preferred embodiment of the utility model, the main clamp bar 15 and the main pull rod 13 are arranged at an angle of 90 degrees, the from clamp bar 16 and the from pull rod 14 are also arranged at an angle of 90 degrees, the connection between the main clamp 17 and the main clamp bar 15 is a first joint, the connection between the main clamp bar 15 and the main pull rod 13 is a second joint, and the pivot is a third joint.

[0024] By arranging the main clamp bar 15 and the main pull rod 13 at an angle of 90 degrees and arranging the from clamp bar 16 and the from pull rod 14 at an angle of 90 degrees, the following effects are mainly achieved:

[0025] Accurate anatomical adaptation: In the human throat, the position and angle of the cricoarytenoid joint are quite special. By setting the reduction forceps to ninety degrees, it can better match the physiological angle of the cricoarytenoid joint, making it easier and more accurate to reach the joint site after insertion into the throat, and allowing it to fit more closely to the joint during operation, thus achieving more accurate reduction operation and reducing the operation errors caused by mismatch between the instrument and the joint.

[0026] Convenient operation and force: The ninety-degree angle design provides a more ergonomic operation method for doctors, allowing the wrist and arm to be in a relatively natural and comfortable position when holding and using the reduction forceps, making it easier to apply force and control the force. This allows doctors to more flexibly adjust the direction and position of the reduction forceps, and to more accurately control the size and direction of the force during reduction operation, avoiding damage to the cricoarytenoid joint and surrounding tissues due to improper force.

[0027] Reducing visual obstruction: When performing a throat surgery or examination, using a ninety-degree cricoarytenoid joint reduction forceps 1 can reduce the obstruction of the surgical or observation field by the instrument to some extent, allowing doctors to see the cricoarytenoid joint and its surrounding tissues more clearly through a laryngoscope or other devices, and to better observe the contact position and state of the reduction forceps with the joint, allowing them to discover and address problems that arise during operation in a timely manner, improving the accuracy and safety of the surgery or examination.

[0028] Expanding the field of vision: The ninety-degree angle setting allows the reduction forceps to spread the surrounding tissues at a more appropriate angle during operation, providing a wider field of vision for doctors, which helps to discover some hidden deep tissue or angle of the lesion or abnormal condition, and is of great significance for comprehensive assessment of the throat condition and development of a more accurate treatment plan.

[0029] Reducing the risk of tissue damage: Due to its ninety-degree angle, the contact between the reduction forceps and the throat tissue during insertion and operation is relatively gentle, reducing the risk of tissue damage caused by scraping and squeezing of the surrounding mucosa, muscle and other tissues. Especially when dealing with some more fragile or easily damaged throat tissues, this angle design can better protect the integrity of the tissues, reduce the incidence of postoperative complications, and promote the recovery of patients.

[0030] Avoiding excessive traction: The appropriate ninety-degree angle allows the reduction forceps to transmit force more evenly and reasonably when pulling or adjusting the cricoarytenoid joint, avoiding excessive traction or torsion caused by improper angle, thus reducing unnecessary damage to the surrounding tissues of the joint and protecting the normal physiological function and structural integrity of the throat tissues.

[0031] In a further preferred embodiment of this utility model, the total length of the arytenoid joint reduction clamp 1 is 21cm, the width of the arytenoid joint reduction clamp 1 is 0.4cm, and the thickness is 0.3cm;

[0032] 4. The length from the first joint point to the second joint point is 7cm, the length from the second joint point to the back of the third joint point is 13cm, and the length from the inner side is 11cm; the length from the third joint point to the main handle 11 is 4.8cm.

[0033] The total length of the cricoarytenoid joint reduction forceps is 21cm. The distance from the mouth or nose to the cricoarytenoid joint in the human larynx varies, and a total length of 21cm generally provides good fit for the anatomical features of most patients. This allows the forceps to be inserted smoothly through the mouth or nose to reach the cricoarytenoid joint for manipulation. It avoids the inconvenience or increased patient discomfort caused by excessive length, and also prevents ineffective access to the manipulation site due to insufficient length. This length makes it easier for the doctor to control the force and direction during operation. The doctor can hold the forceps relatively stably and flexibly adjust the position and posture of the forceps head in the larynx through natural wrist and arm movements, performing precise reduction or other related operations, reducing operational difficulties and errors caused by instruments that are too long or too short.

[0034] In a further preferred embodiment of this utility model, both the main clamp 17 and the slave clamp 18 are provided with anti-slip threads 19 on their inner sides;

[0035] In cases of acute dislocation of the cricoarytenoid joint caused by trauma, improper endotracheal intubation, or other procedures, the cricoarytenoid joint reduction forceps can be used to directly reduce the dislocated joint and restore its normal anatomical position. This can quickly improve symptoms such as hoarseness, choking when drinking, and difficulty breathing caused by the dislocation, prevent further deterioration of the condition, and promote the early recovery of the patient's laryngeal function.

[0036] For some chronic cricoarytenoid joint dislocations that have not been detected and treated in time, reduction forceps can also serve as an important treatment tool. Through meticulous manipulation, the adhesions around the joint are gradually released, and the joint position is adjusted to restore it to its normal functional position as much as possible. Although the treatment is relatively difficult, it may still improve the patient's laryngeal function and quality of life. The main forceps 17 and the secondary forceps 18 are both equipped with anti-slip threads 19 on their inner sides, and both the main forceps 17 and the secondary forceps 18 are positioned opposite each other and are oval in shape, which can better grip cotton pads and gauze. The blunt forceps increase resistance and protect cotton pads and ruptured mucosa.

[0037] The above merely describes the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of claims of the present application.
