Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a dental surgical needle. Background Art

[0002] In cosmetic dental restoration, a bur can be used to polish away minor flaws on the tooth surface, such as stains and light scratches, to make the tooth surface smoother. A handle is usually provided at one end of the bur, so the doctor can comfortably hold the handle during dental surgery, allowing for precise control of the direction and force of the bur. In the prior art, the bur is tightly connected to the handle, and when the bur needs to be separated from the handle, it is difficult to pull them out simply by hand. The doctor may resort to small tools, such as tweezers or pliers. This method may cause scratches and other damage to the bur or the handle. During the separation process, the force applied by the tool to the bur is uneven, which may cause the bur body to bend or deform. Once the bur is deformed, it will shake when rotating at high speed, making it impossible to operate accurately and causing accidental damage to the teeth and surrounding tissues.

[0028] Example 1

[0029] Reference Figures 1-6, which is the first embodiment of the present invention, provides a dental surgical needle. The dental surgical needle includes a main body component 100, a locking component 200 and a driving component 300. The three can be combined to facilitate the disassembly and assembly of the needle.

[0030] Specifically, the engaging assembly 200 includes an engaging member 201, including a fixed base 201a, a protrusion 201b, a rotating ring 201c, a gear ring 201d, and a block 201e. There are two protrusions 201b, both of which are disposed on one side of the fixed base 201a for engagement. The fixed base 201a is disposed on one side of the protrusion 201b. There are two rotating rings 201c, both of which are disposed on one side of the protrusion 201b. The gear ring 201d is disposed on one side of the rotating ring 201c. The block 201e is disposed on the inner wall of the gear ring 201d for engagement.

[0031] The inner wall of the fixed base 201a is provided with grooves corresponding to the protrusions 201b.

[0032] A slot corresponding to the block 201e is provided on the gear ring 201d, and the block 201e is set as an inclined surface. When the needle body 103 needs to be fixed, the fixed base 201a is placed on the inner wall of the connector 102, and the rotating ring 201c is rotated to drive the protrusion 201b to engage with the connector 102, thereby completing the installation of the needle body 103. When the rotating ring 201c rotates, it will also drive the rotating shaft 202a to rotate.

[0033] When the rotating shaft 202a rotates, it will drive the block 201e to rotate. At this time, the inclined slot can squeeze the block 201e, so that the block 201e is separated from the slot. When the block 201e rotates to the side of the next slot, the block 201e will return to its original position and re-engage with the slot. The setting of the slot can prevent the block 201e from reversing, and thus prevent the rotating shaft 202a from driving the rotating ring 201c to reverse, so that the needle body 103 can be firmly fixed in the connector 102.

[0034] Specifically, the driving assembly 300 is arranged on one side of the rotating circle 201c, and includes a driving member 301, including a connecting shaft 301a, a rotating disk 301b and a driving bar 301c.

[0035] By moving the driving bar 301c, the driving bar 301c presses the rotating disk 301b, and the rotating disk 301b rotates to drive the connecting shaft 301a to rotate. The rotation of the connecting shaft 301a can make the rotating shaft 202a rotate.

[0036] Example 2

[0037] Reference Figures 1-6 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0038] Specifically, the inner wall of the rotating circle 201c is plugged with a rotating shaft 202a, and support plates 202b are sleeved on both sides of the rotating shaft 202a. The rotating shaft 202a is movably connected to the support plates 202b.

[0039] The support plate 202b is used to support the rotating shaft 202a, and the rotating shaft 202a is used to support the rotating circle 201c. The rotating circle 201c can be driven to rotate by the rotation of the rotating shaft 202a.

[0040] Specifically, a driving disk 202c is provided at one end of the rotating shaft 202a, a rotating groove 202c-1 is opened on the inner wall of the driving disk 202c, and a rotating bar 202d is inserted into the inner wall of the rotating groove 202c-1.

[0041] The rotating bar 202d is used to support the block 201e, and the driving disk 202c is used to support the rotating bar 202d. When the base 201a needs to be fixed and engaged with the protrusion 201b, the driving disk 202c is rotated, and the driving disk 202c rotates to drive the block 201e to rotate, and the block 201e drives the ring gear 201d to rotate. The rotation of the driving disk 202c will drive the rotating shaft 202a to rotate.

[0042] Specifically, a clamping block 201e is sleeved on the outer side of the rotating bar 202d, a first spring 202e is fixed to the bottom of the clamping block 201e, and the other end of the first spring 202e is fixed to the inner wall of the rotating groove 202c-1.

[0043] When the engagement between the fixed base 201a and the protrusion 201b needs to be canceled, the block 201e is pressed, and the block 201e presses the first spring 202e, so that the first spring 202e is separated from the slot.

[0044] Specifically, a handle 202f is fixed to one side of the clamping block 201e, and the gear ring 201d is sleeved on the outside of the driving disk 202c.

[0045] By turning the handle 202f, the movement of the handle 202f can drive the block 201e to move.

[0046] Specifically, one end of each driving bar 301c is plugged with a movable shaft 302a, and a pressing plate 302b is provided at the bottom of the movable shaft 302a. The movable shaft 302a is movably connected to the driving bar 301c.

[0047] By moving the driving bar 301c, the driving bar 301c drives the movable shaft 302a to move, and the movable shaft 302a drives the extrusion plate 302b to move. The movement of the extrusion plate 302b can make the fixed base 201a engage with the protrusion 201b.

[0048] Example 3

[0049] Reference Figure 5-Figure 6 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0050] Specifically, a push plate 302c is provided at one end of the extrusion plate 302b, and a second spring 302d is fixed to one end of the push plate 302c.

[0051] By pushing the pressing plate 302b, the pressing plate 302b presses the pushing plate 302c, and the pushing plate 302c presses the second spring 302d.

[0052] Specifically, a fixing block 302e is fixed to one end of the second spring 302d, and an extrusion ring 302f is provided at the other end of the extrusion plate 302b.

[0053] The fixing block 302e is used to support the other end of the second spring 302d.

[0054] By squeezing the squeezing ring 302f, the squeezing ring 302f drives the squeezing plate 302b to move, the squeezing plate 302b drives the pushing plate 302c to squeeze the second spring 302d, and the second spring 302d squeezes the fixing block 302e.

[0055] Specifically, a protective frame 302g is provided on the outer side of the extrusion plate 302b.

[0056] The protection frame 302g is used to protect the extrusion plate 302b.

[0057] Specifically, it also includes a main body component 100, including a handle 101, a connecting head 102 and a needle body 103. The connecting head 102 is arranged at one end of the handle 101, the handle 101 is arranged at one end of the connecting head 102, the needle body 103 is arranged on the inner wall of the connecting head 102, the fixed base 201a is arranged on the inner wall of the connecting head 102, and the needle body 103 is arranged at one end of the fixed base 201a.

[0058] The design of the handle 101 is ergonomic and convenient for the doctor to hold. The other end of the handle 101 is usually connected to the working part of the needle, and the specific structure of the handle 101 can make it tightly connected to the dental handpiece. The connector 102 is used to support the needle body 103. The needle body 103 usually has a specific shape and cutting edge, and can rotate or reciprocate at high speed to perform operations such as cutting, grinding, and trimming teeth.

[0059] The needle body 103 is disposed at one end of the fixed base 201 a.

[0060] During use, when the needle body 103 and the connector 102 need to be installed, the fixed base 201a is placed on the inner wall of the connector 102, and then the extrusion ring 302f is squeezed. The extrusion ring 302f drives the extrusion plate 302b to move, and the extrusion plate 302b drives the push plate 302c to squeeze the second spring 302d. When the extrusion plate 302b moves, it also drives the driving bar 301c to move. The driving bar 301c squeezes the rotating disk 301b, and the rotation of the rotating disk 301b drives the connecting shaft 301a to rotate. The rotation of the connecting shaft 301a can make the rotating shaft 202a rotate, and the rotating shaft 202a drives the rotating ring 201c to rotate. The rotation of the rotating ring 201c drives the protrusion 201b to engage with the groove on the inner wall of the connector 102 and the fixed base 201a, thereby completing the installation of the needle body 103. When the rotating shaft 202a rotates, it will drive the block 201e to rotate. At this time, the inclined groove can squeeze the block 201e, thereby separating the block 201e from the groove. When the block 201e rotates to the side of the next groove, the block 201e will return to its original position and re-engage with the groove. The setting of the groove can prevent the block 201e from reversing, thereby preventing the rotating shaft 202a from driving the rotating ring 201c to reverse, so that the needle body 103 can be firmly fixed in the connector 102.

[0061] When the needle body 103 needs to be removed, the handle 202f is pressed, and the handle 202f drives the block 201e to separate from the slot. When the block 201e is separated from the slot, the first spring 202e can be squeezed to separate the block 201e from the slot, thereby releasing the limit of the driving disk 202c. Then, the second spring 302d rebounds, and the squeezing plate 302b returns to its original position, thereby causing the rotating disk 301b to drive the driving disk 202c to reverse. The reverse rotation of the driving disk 202c drives the rotating circle 201c to reverse, so that the rotating circle 201c is separated from the fixed base 201a, so that the needle body 103 can be taken out.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
