Technical Field

[0001] The utility model belongs to the field of dental implantation, in particular to an extension rod for implantation. Background Art

[0002] With the rapid development of dental implant systems, various dental implant tools have emerged one after another. Under the premise of meeting the requirements for tool use, it is very necessary to optimize the structure of current tools so that they have the characteristics of appropriate processing cost and simple maintenance.

[0003] When performing implant surgery in the posterior tooth area, the implant mobile phone needs to go deep into the oral cavity to prepare the hole. The distance between the mobile phone head and the operating environment in the oral cavity is too close. At this time, the dental drill is not long enough to complete the cavity preparation. Utility Model Content

[0004] In view of this, the utility model aims to propose an extension rod for implantation, which extends the dental drill and realizes the function of separate replacement by designing a sleeve, thereby extending the service life and reducing the production cost.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] An implant extension rod, used for extending a dental implant surgical tool; comprising an extension rod body and a ferrule;

[0007] A connecting part is provided at the end of the dental drill, and the connecting part is inserted into the extension rod body. The clamping groove can be sleeved with the extension rod body and can also clamp the connecting part, so that the dental drill, the extension rod body and the clamping sleeve are connected to form an integrated structure.

[0008] Furthermore, the connecting portion is provided with an annular groove, and one side of the connecting portion is provided with a right-angle notch, and the width of the straight notch is equal to the width of the annular groove.

[0009] Further, the extension rod body includes a sleeve and an extension rod body; the extension rod is mounted to the end of the sleeve;

[0010] A matching groove is arranged in the sleeve, and a matching window communicating with the matching groove is arranged on the surface of the sleeve; a step structure is formed at the connection between the extension rod body and the sleeve.

[0011] Further, a matching step is provided in the matching groove, and the matching step corresponds to the matching window;

[0012] The straight notch of the connecting part fits with the matching step, and the right-angle notch contacts with the matching step to form a limit.

[0013] The annular groove of the connecting portion is exposed through the matching window.

[0014] Furthermore, the clamping sleeve includes a clamp and a buckle, and the buckle is connected to the end surface of the clamp;

[0015] The clamp is sleeved onto the extension rod body; the buckle is clamped through the matching window and the annular groove of the connecting part, thereby realizing the connection between the dental drill, the extension rod body and the clamping sleeve.

[0016] Furthermore, a positioning groove is provided above the matching window, and the positioning groove corresponds to the buckle to achieve positioning of the buckle.

[0017] Furthermore, a connecting portion is also provided on the extension rod body, and the connecting portion of the extension rod body has the same structure as the connecting portion of the dental drill.

[0018] Compared with the prior art, the planting extension rod described in the utility model has the following advantages:

[0019] The utility model discloses an extension rod for implantation, which adds a composite material elastic sleeve, and changes the original stainless steel spring clip clamping structure, so that the processing cost of the entire extension rod is greatly reduced; after long-term use, the elastic sleeve is worn out, resulting in a poor limiting effect of the dental drill, and only the elastic sleeve needs to be replaced separately, and the stainless steel extension rod main body can be used continuously, and the service life of the entire extension rod is greatly improved; since the overall structure of the extension rod and the dental drill is small and slender, when the dental drill is separated from the extension rod, the dental drill can only be pulled outwards due to insufficient force points. After the structure is improved, it only needs to slightly apply force outwards to the elastic sleeve, and the sleeve can fall off. Without the limiting effect of the sleeve, the dental drill falls out naturally, and the insertion and extraction of the dental drill are more convenient and quick, the doctor's user experience is improved, and the efficiency and quality of the operation are further improved.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] An implant extension rod is used to extend a dental implant surgical tool; Figure 1-Figure 4 As shown, it includes an extension rod body 1 and a ferrule 2; there are many types of dental implant surgeries, and a dental drill 3 is used as an example here;

[0032] A connecting portion 4 is provided at the end of the dental drill, and the connecting portion 4 is inserted into the extension rod body 1. The clamping groove can be sleeved with the extension rod body 1 and can also clamp the connecting portion 4, so that the dental drill, the extension rod body 1 and the clamping sleeve 2 are connected to form an integrated structure.

[0033] Preferably, the connecting portion 4 is provided with an annular groove 41, and a right-angle notch 42 is provided on one side of the connecting portion 4, and the width of the straight notch is equal to the width of the annular groove 41. The dental implant surgery tool is provided with a connecting portion 4 for quick connection with a mobile phone;

[0034] Preferably, the extension rod body 1 comprises a sleeve 11 and an extension rod body 12; the extension rod is mounted to the end of the sleeve 11;

[0035] A matching groove 14 is provided in the sleeve 11, and a matching window 13 communicating with the matching groove 14 is provided on the surface of the sleeve 11; a step structure is formed at the connection between the extension rod body 12 and the sleeve 11; the step structure is used to cooperate with the sleeve 11 to form a limit;

[0036] Preferably, the matching groove 14 is provided inside a matching step 15, and the matching step 15 corresponds to the matching window 13;

[0037] The dental drill is inserted into the sleeve 11, the straight notch of the connecting portion 4 fits with the matching step 15, and the right-angle notch 42 contacts with the matching step 15 to form a limit.

[0038] The annular groove 41 of the connecting portion 4 is exposed through the matching window 13 to facilitate matching with the ferrule 2 .

[0039] Preferably, the ferrule 2 includes a clamp 21 and a buckle 22, and the buckle 22 is connected to the end surface of the clamp 21; the ferrule 2 is made of elastic material as a whole; the clamp 21 is an open structure, and can be quickly tightened in combination with the elastic material.

[0040] The clamp 21 is sleeved onto the extension rod body 12 ; the buckle 22 is clamped with the annular groove 41 of the connecting portion 4 through the matching window 13 , thereby achieving connection among the dental drill, the extension rod body 1 and the clamping sleeve 2 .

[0041] Preferably, a positioning groove 16 is provided above the matching window 13 , and the positioning groove 16 corresponds to the buckle 22 to achieve positioning of the buckle 22 . By providing the positioning groove 16 , the sleeve 11 can be quickly positioned.

[0043] The use of elastic material for the sleeve 11 can increase the service life. Existing extension rods are mostly made of stainless steel. Stainless steel is in close contact with stainless steel. Long-term plugging and unplugging will cause the buckle 22 to wear out. The anti-movement ability of the buckle 22 will become weaker and weaker, and the stability of the fit will be weakened. Long-term use will lead to a decrease in the final planting effect. In terms of processing, the processing of the buckle 22 is also relatively complicated. The thickness of the spring sheet must ensure that the elastic force is sufficient to press the tool to be lengthened, but not too much elastic force will be applied to affect the plug-in feel, and further accelerate the wear process;

[0044] The original integrated structure of the buckle 22 and the extender is improved to a split design. The extender is divided into a main body and a ferrule 2. The ferrule 2 is replaced with an elastic composite material. The ferrule 2 can be replaced separately to reduce costs and increase life. When the drill bit needs to be replaced.

[0045] When in use, push the end of the connecting part 4 of the tool to be extended into the extension rod, see through the observation window that the anti-channeling groove has reached a suitable position, clamp the ferrule 2 on the handle along the end surface, pull the implant tool up and down or turn it left and right, and find that the implant tool and the extension rod are relatively locked, and the installation is completed. After the operation is completed, remove the ferrule 2 and pull the implant tool naturally out along the axial direction.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
