Detailed Description

In order that the above-recited objects, features and advantages of the present utility model will be more clearly understood, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description. In addition, embodiments of the present application and features of the embodiments may be combined with each other without conflict. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, and the described embodiments are merely some, rather than all, embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

As shown in fig. 1-5, the utility model specifically discloses a ligature handle for a lingual appliance, which comprises a lantern ring and a holding rod arranged on the lantern ring, wherein the lantern ring and the holding rod are integrally formed, a sleeve hole is arranged in the middle of the lantern ring, the sleeve hole can accommodate an appliance, a plurality of guide posts are arranged along the edge of the sleeve hole, and the guide posts can be fixedly connected with the lantern ring in a threaded connection or welding way.

When ligature is carried out on the appliance, the outer side of the holding rod is held, the lantern ring at the other end of the holding rod stretches into the oral cavity of a patient, then the trepanning is aligned to the appliance to be sleeved on the periphery of the appliance, then the ligature ring is sleeved on the guide posts by using tools such as hooks or forceps and the like, the ligature ring is an elastic ligature ring and has ductility, so that the ligature ring can be spread on the guide posts by using tools such as hooks or forceps and the like, thereby being convenient for medical staff to operate the ligature ring, and after the ligature ring is operated, the ligature ring is stirred by using tools such as hooks or forceps and the like to be separated from the guide posts and is pulled into the bracket of the appliance in the middle, so that the ligature process of the appliance is completed. Compared with the conventional ligation operation directly performed through a hook or a tweezer and other tools, the ligation ring is spread through the guide post to perform the ligation operation, so that more operation space is obtained, the operation difficulty is greatly reduced, the operation time is further shortened, and the discomfort of a patient is reduced.

In some alternative embodiments, as shown in fig. 2-3, the end of the guide post is provided with a hook, the hook extends outwards away from the trepanning, and by providing the hook extending outwards, the ligature loop is prevented from being separated from the guide post as much as possible in the process of adjusting the ligature loop, so that the operation flow is affected, the distance between the end of the further hook and the outer side of the guide post can be 1mm-1.5mm, the situation that the ligature loop falls off in the adjusting process can be avoided as much as possible, and the ligature loop can be conveniently taken off from the guide post after the ligature loop is adjusted, and is sleeved in a bracket of the appliance.

In some alternative embodiments, as shown in fig. 4-5, the end of the guide post is provided with a bump, the bump is cylindrical as shown in fig. 4, and of course, the bump may be a hemisphere, a table, a cone, etc., as long as the bottom surface of the bump can completely cover the end of the guide post and extend outwards, and the portion extending outwards through the bump limits the binding ring during the adjustment of the binding ring, so that the binding ring is prevented from being separated from the guide post as much as possible, thereby reducing the influence on the operation procedure, the distance between the end surface extending outwards of the further bump and the outer side of the guide post may be 1mm-1.5mm, the situation that the binding ring falls off during the adjustment process can be avoided as much as possible, and the binding ring can be conveniently removed from the guide post after the adjustment of the binding ring is completed and sleeved in the bracket of the appliance.

In some optional embodiments, the guide pillar side wall is equipped with anti-skidding line, when the ligature snare was established on the guide pillar, the ligature circle can be because self elasticity is leading to the upper slide, in order to reduce the range that the ligature circle slided, is provided with the anti-skidding line that increases friction on the guide pillar to increase the degree of difficulty that the ligature circle slided, and then improved the stability of operation.

In some alternative embodiments, the length of the grip is at least 120mm, the width of the grip is at least 5mm, and in particular, the length of the grip shown in fig. 1 is 130mm and the width is 6mm, and the arrangement of the length and the width of the grip can ensure that the medical staff has better holding hand feeling.

In some alternative embodiments, because the operation needs to be performed in the oral cavity of the patient, and the operation space in the oral cavity of the patient is limited, if the common holding rod is directly stretched into the oral cavity of the patient, the operation of the medical staff may be limited due to the wide width of the holding rod, and the holding rod gradually narrows inwards towards one end of the lantern ring, so that the holding rod is reduced to occupy the space in the oral cavity, more operation space is brought for the operation, and the operation efficiency of the medical staff is improved.

In some alternative embodiments, a ring groove is arranged on the outer side of the rod body of the holding rod, so that friction between the hand and the holding rod is increased, the holding of medical staff is firmer, and stability in the operation process is improved.

The present utility model is not limited to the preferred embodiments, and any modifications, equivalent variations and modifications made to the above embodiments according to the technical principles of the present utility model are within the scope of the technical proposal of the present utility model.
