Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to a detachable universal root collar. Background Art

[0002] In alveolar surgery, instruments such as root collars or triangular collars are required to remove residual roots and the roots remaining after the impacted teeth are separated. Residual roots refer to teeth whose crowns have decayed or broken, leaving only the roots in the alveolar bones of the upper and lower jaws. They are generally difficult to retain and need to be extracted. Mandibular third molars are often impacted teeth, which can easily cause inflammation of the adjacent soft tissues, causing caries and apical periodontitis of the adjacent teeth. They should be extracted when they meet the indications for extraction. In both cases, the roots are located relatively deep, and conventional dental forceps cannot be used to clamp and extract the roots, so root collars or triangular collars are needed to remove them.

[0003] For tooth roots in different spatial positions, the root collar can provide axial traction, and the triangular collar can provide traction perpendicular to the axial direction. When the tip of the two blades is against different root surface areas or the traction force is used in different directions, the effect of root dislocation will be affected. The curved root collar and triangular collar in the existing root collars are generally designed in pairs. The design of the existing root collar and triangular collar is not very reasonable. When used, they are divided into two directions, inner and outer, according to different dislocation directions. The working blade ends of the instruments are axially symmetrical to each other. It is necessary to distinguish the instrument to be selected according to the mode of root dislocation and the direction of wrist force during the operation. If the selection is wrong, it is necessary to reopen another instrument package to take out the instrument. Not only does it increase the time consumption of the operation and is not conducive to the timely operation of the doctor, but it also increases the amount of instruments to be handled during the postoperative instrument recovery, disinfection and sterilization process. For this reason, a detachable universal root collar is proposed. Summary of the invention

[0004] The object of the present invention is to provide a detachable universal root collar, aiming to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A detachable universal root collar, comprising:

[0007] A collar handle, wherein a spring buckle is provided inside the collar handle, and a button is provided on one side of the collar handle;

[0008] A collar rod, either end of which is built into the collar handle;

[0009] The collar blade is connected to both sides of the collar rod, and a groove is provided on the collar blade. The groove is located on the working surface of the collar blade and is recessed inwardly, and the curvature of the groove corresponds to the physiological curvature of the human tooth root; the tips of the collar blades on both sides are oriented in the same direction, and the working surface grooves face the same direction.

[0010] Furthermore, the collar blade is shaped like an equilateral triangle, and the long axis of the collar blade forms an angle of 90° with the collar rod.

[0011] Furthermore, the spring buckle comprises:

[0012] A pusher, which is limitedly slidably arranged in the collar handle;

[0013] A buckle is slidably arranged in the collar handle;

[0014] The spring is sleeved on the buckle, and two ends of the spring are respectively connected with the buckle and the collar handle.

[0015] Furthermore, a clamping edge area is formed between the pushing member and the buckle.

[0016] Furthermore, a groove is provided at the bottom of the collar handle.

[0017] Furthermore, any one end of the collar rod enters from the groove and is built into the collar handle.

[0018] Furthermore, the collar blade connected to one side of the collar rod is blade one, and the collar blade connected to the other side of the collar rod is blade two.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention sets double-headed collar blades that are axially symmetrical to each other and located on the same collar rod, so that the opposite dislocation force can be applied without reselecting and replacing another instrument. When the present invention is used in tooth extraction in alveolar surgery, if the surgeon finds that the force direction is not ideal, the clamping force on the collar blade can be immediately applied or released to achieve the replacement of the collar blade. The axial symmetry of the collar blades at both ends is used to change the direction of the axle force, which solves the problem of frequent replacement of instruments due to the inability to identify the use direction when using root collars or triangular collars, facilitates intraoperative operations, and also reduces the manufacturing and disinfection costs of medical devices.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1-5 As shown, a detachable universal root collar provided by an embodiment of the present invention includes:

[0030] A collar handle 1, a slot 15 is provided at the bottom of the collar handle 1, a spring buckle is provided inside the collar handle 1, and a button 14 is provided on one side of the collar handle 1;

[0031] A collar rod 2, either end of which enters from the slot 15 and is built into the collar handle 1;

[0032] The collar blade 3 is connected to both sides of the collar rod 2. The collar blade 3 is provided with a groove, which is located on the working surface of the collar blade 3 and is recessed inwardly. The curvature of the groove corresponds to the physiological curvature of the human tooth root. The collar blade 3 is shaped like an equilateral triangle, and the long axis of the collar blade 3 forms an angle of 90° with the collar rod 2. The tips of the collar blades 3 on both sides are oriented in the same direction, and the working surface grooves are facing the same direction.

[0033] In the embodiment of the present invention, after the collar rod 2 is inserted into the collar handle 1 through the slot 15, the spring buckle clamps the collar blade 3 to prevent the collar handle 1 from loosening and shifting. After pressing the button 14 on one side of the collar handle 1, the spring buckle can be pushed open to release the clamped collar rod 2 and pull it out from the bottom of the collar handle 1.

[0034] like Figure 1-4 As shown, as a preferred embodiment of the present invention, the spring buckle comprises:

[0035] A push member 13 is limitedly slidably disposed in the collar 1, and the push member 13 is fixedly connected to the button 14;

[0036] The buckle 11 is slidably disposed in the collar handle 1; a clamping edge area is formed between the pusher 13 and the buckle 11;

[0037] The spring 12 is sleeved on the buckle 11, and two ends of the spring 12 are respectively connected to the buckle 11 and the collar 1.

[0038] In the embodiment of the present invention, the buckle 11 and the pushing piece 13 are both irregular metal sheets with a certain thickness; the collar handle 1 is made of solid metal, and a sliding groove 16 for the buckle 11 and the pushing piece 13 to slide is provided in the middle of the collar handle 1, and the metal around the sliding groove 16 constitutes a limiting piece for the buckle 11 and the pushing piece 13. The specific operation of replacing the collar blade 3 is as follows: during the root collar removal process, if the doctor needs to replace the collar blade 3, he presses the button 14 with the thumb of his right hand, so that the pushing member 13 pushes the buckle 11 away from the collar blade 3, thereby releasing the clamping state of the buckle 11 on the collar blade 3, and the collar handle 1 can be taken out. After rotating the collar handle 1 180°, press the button 14 again, and insert the side of the collar blade 3 to be replaced into the collar handle 1. After releasing the button 14, the spring 12 drives the buckle 11 to return to its original position, thereby clamping the collar blade 3, and the buckle 11 drives the button 14 to move, and the button 14 abuts against the side wall of the collar handle 1 to return to its original position, and the replacement of the collar blade 3 is completed.

[0039] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the collar blade 3 connected to one side of the collar rod 2 is blade one 31, and the collar blade 3 connected to the other side of the collar rod 2 is blade two 32.

[0040] In the embodiment of the present invention, the specific operation of selecting the collar blade 3 is: during the root collar removal process, the doctor is located on the right side of the patient and uses his right hand to hold the collar handle 1. When using the invention to push out the tooth root, if the fulcrum of the collar blade 3 is located above the tooth root, use the blade one 31; if the fulcrum of the collar blade 3 is located below the tooth root, use the blade two 32.

[0041] The working principle of the present invention is:

[0042] In the process of removing the tooth root collar of the detachable universal root collar, the doctor is located on the right side of the patient and holds the collar handle 1 with his right hand. When using the root collar to push out the tooth root, if the fulcrum of the collar blade 3 is located above the tooth root, the first blade 31 is used, and if the fulcrum of the collar blade 3 is located below the tooth root, the second blade 32 is used. If the collar blade 3 needs to be replaced, the button 14 is pressed by the thumb of the right hand so that the pusher 13 pushes the buckle 11 away from the collar blade 3, thereby releasing the clamping state of the buckle 11 on the collar blade 3, and the collar handle 1 can be taken out. After rotating the collar handle 1 180°, the button 14 is pressed again, and the side of the collar blade 3 to be replaced is inserted into the collar handle 1. After releasing the button 14, the spring 12 drives the buckle 11 to return to its original position, thereby clamping the collar blade 3, and the replacement of the collar blade 3 is completed.

[0043] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
