Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a pair of technician pliers for assembling prefabricated crowns. Background Art

[0002] Prefabricated crowns are typically made of resin, ceramic, or metal. They offer excellent durability and aesthetics. Compared to full crowns made directly on the tooth, prefabricated crowns are quicker to produce and relatively inexpensive. Therefore, they are often used to repair mild to moderate tooth damage, such as decay, fractures, or wear.

[0003] Currently, when a prefabricated crown is assembled on the surface of a tooth crown, a doctor, wearing sterile gloves, pinches the prefabricated crown with his hands, inserts it into the patient's mouth, and puts the prefabricated crown on the surface of the tooth crown with his hands.

[0004] This method of operation has hidden dangers when dealing with children: since children's mouths are much smaller than those of adults, it is more troublesome for the doctor to put his fingers into the child's mouth. Moreover, the prefabricated crown may fall into the child's mouth when held in hand. Since children have weak self-control, they can easily swallow the prefabricated crown when swallowing saliva. Summary of the Invention

[0005] The purpose of the utility model is to address the problems existing in the prior art and provide a technician's pliers for assembling prefabricated crowns to replace manual assembly of prefabricated crowns. The operation is more convenient, the control over the prefabricated crowns is stronger, and it is not easy to fall into the mouths of children, thereby greatly reducing safety hazards.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a kind of technician pliers for prefabricated crown assembly, comprising a technician pliers body, the pliers mouth of the technician pliers body is provided with an anastomosis device, the anastomosis device comprises a first anastomosis part and a second anastomosis part, the first anastomosis part and the second anastomosis part are respectively provided with an anastomosis groove on the opposite side, and the first anastomosis part and the second anastomosis part are both provided with a plug-in inserted into the inside of the pliers mouth of the technician pliers body on the side close to the pliers mouth of the technician pliers body.

Compared with manual operation, the technician's forceps body clamps the prefabricated crown more stably through the anastomosis device, and the prefabricated crown will not fall off during the process of being sent into the mouth and inserted into the crown, which may cause the child to accidentally swallow it. This greatly improves the safety of fitting prefabricated crowns for children. In addition, the use of the technician's forceps body instead of manual labor can make the prefabricated crown more accurate when inserted into the crown.

[0008] Furthermore, the jaws of the mechanic pliers body are eagle-beak-shaped, and a socket adapted to the plug-in is provided at the end of the jaws of the mechanic pliers body.

[0009] The eagle-beak-shaped mouth of the forceps can better adapt to the curvature of the oral cavity, making it more convenient for the doctor to insert the prefabricated crown into the tooth crown.

[0010] Furthermore, the plug-in is a multi-faceted prism, and a damping pad is provided on each side of the plug-in.

[0011] The pluggable design and multi-faceted prism design of the stapler ensure stability after the plug-in is connected to the pliers mouth of the mechanic forceps body, and the damping pad makes the plug-in connection more secure.

[0012] Furthermore, a plurality of the staplers are provided, and the size of the stapler groove on each stapler is different, and the depth of the stapler groove is smaller than the thickness of the stapler.

[0013] Anastomotic grooves of different sizes can be adapted to prefabricated crowns of different sizes by simply replacing the corresponding anastomosis device. In addition, the depth of the anastomosis groove is smaller than the thickness of the anastomosis device, allowing the anastomosis device to wrap around the head of the prefabricated crown during clamping, making the clamping more stable.

[0014] Furthermore, the first anastomosis member and the second anastomosis member are both provided with mutually attracting magnetic blocks on one side close to the pliers mouth of the mechanic pliers body, and the plug-in is installed at one end of the magnetic block.

[0015] The magnetic block allows the first anastomotic piece and the second anastomotic piece in a pair of staplers to always stick together when idle, making them easy to take out and replace.

[0016] Furthermore, a positioning protrusion is provided on one side of one magnetic block facing the other magnetic block, and a positioning groove adapted to the positioning protrusion is provided on one side of the other magnetic block.

[0017] By means of the positioning protrusion and the positioning groove, the two magnetic blocks are partially embedded in each other when they are adsorbed to each other, so that the first anastomotic piece and the second anastomotic piece in a pair of anastomotic devices can be more stably adsorbed.

[0018] Furthermore, a spring member is provided on the inner side of the handle portion of the mechanic's pliers body.

[0019] The spring element provides an outward thrust to the handle portion of the mechanic's pliers body, and the mechanic's pliers body does not need to be opened and closed manually.

Therefore, they cannot be understood as limitations on the present invention.

[0030] like Figure 1 -3, the specific scheme of the embodiment is as follows: a technician pliers 1 for prefabricated crown assembly, comprising a technician pliers body 1, a pliers mouth portion of the technician pliers body 1 is provided with an anastomosis device 2, the anastomosis device 2 comprises a first anastomosis member 21 and a second anastomosis member 22, an anastomosis groove 23 is respectively provided on the opposite side of the first anastomosis member 21 and the second anastomosis member 22, and a plug-in 4 is inserted into the inside of the pliers mouth portion of the technician pliers body 1 on the side of the first anastomosis member 21 and the second anastomosis member 22 close to the pliers mouth portion of the technician pliers body 1.

[0031] The anastomosis device 2 that matches the size of the prefabricated crown is used to stably clamp the prefabricated crown, replacing manual insertion of the prefabricated crown onto the surface of the child's crown. Compared with manual operation, the technician forceps body 1 clamps the prefabricated crown more stably through the anastomosis device 2, and the prefabricated crown will not fall off during the process of being sent into the mouth and inserted into the crown, which may cause the child to accidentally swallow it. This greatly improves the safety of fitting prefabricated crowns for children. In addition, using the technician forceps body 1 instead of manual labor can make the prefabricated crown more accurate when inserted into the crown.

[0032] In this embodiment, the jaws of the technician's pliers body 1 are eagle-beak shaped, and the length of the jaws is not less than 4 cm. The eagle-beak shaped jaws can better fit the curvature of the oral cavity, making it more convenient for the doctor to insert the prefabricated crown into the tooth crown.

[0033] In this embodiment, the plug-in 4 is a multi-faceted prism, and a damping pad 41 is provided on each side of the plug-in 4 . Meanwhile, a socket adapted to the plug-in 4 is provided at the end of the jaws of the pliers body 1 .

[0034] In this embodiment, the anastomosis device 2 is made into a pluggable design and adopts a multi-faceted prism, so that after the plug-in 4 is plugged into the jaws of the pliers body 1, stability is ensured, and the damping pad 41 makes the plug-in 4 more firmly plugged.

[0035] It should be noted that there are multiple staplers 2, and the sizes of the stapler grooves 23 on each stapler 2 are different. The stapler grooves 23 of different sizes are adapted to preformed crowns of different sizes, so it is only necessary to replace the corresponding stapler 2.

[0036] like Figure 4 As shown, the depth of the anastomosis groove 23 is less than the thickness of the stapler 2, so that the stapler 2 can wrap around the head of the preformed crown during clamping, thereby making the clamping more stable.

[0037] like Figure 3 As shown, the first anastomosis piece 21 and the second anastomosis piece 22 are provided with a magnetic block 3 that attracts each other on one side of the pliers mouth of the technician's pliers body 1, and the plug-in 4 is installed at one end of the magnetic block 3; the magnetic block 3 allows the first anastomosis piece 21 and the second anastomosis piece 22 in a pair of anastomosis devices 2 to always stick together when idle, which is convenient for taking and replacing.

[0038] In addition, a positioning protrusion 31 is provided on the side of one of the magnetic blocks 3 facing the other magnetic block 3, and a positioning groove adapted to the positioning protrusion 31 is provided on one side of the other magnetic block 3; through the positioning protrusion 31 and the positioning groove, the two magnetic blocks 3 are partially embedded in each other when they are adsorbed against each other, so that the first anastomosis part 21 and the second anastomosis part 22 in a pair of anastomosis devices 2 can be more stable when adsorbed.

[0039] like Figure 1 As shown, a spring member 5 is provided on the inner side of the handle portion of the mechanic pliers body 1 , and the spring member provides an outward thrust to the handle portion of the mechanic pliers body 1 , eliminating the need to manually open and close the mechanic pliers body 1 .
