Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a mold clamp and a surgical robot. Background Art

[0002] In the field of dentistry, accurate acquisition of impression materials is one of the key steps in making precise restorations (such as dentures, crowns, etc.). This process usually relies on impression fixtures to stabilize and fix the impression materials in the patient's mouth to ensure that the impression can accurately replicate the morphology of the teeth and surrounding tissues.

[0003] In the prior art, the impression fixture includes two relatively fixed splints, a space filled with impression material is formed between the two splints, and then the impression fixture containing the impression material is inserted on the patient's teeth so that the impression can fully simulate the shape of the patient's teeth.

[0004] However, when removing the impression fixture from the patient's teeth, since the impression material has already solidified, a large external force needs to be applied to remove the impression fixture, causing the patient's teeth to be subjected to a large tensile force, which can easily cause damage to the patient's loose teeth. Utility Model Content

[0005] The utility model aims to provide an impression clamp and a surgical robot, which solve the problem in the prior art that when the impression clamp is removed, the patient's teeth need to bear a large pulling force, which causes the loose teeth to be easily damaged.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] In a first aspect, the utility model provides a die holder, which comprises:

[0008] A first plug-in board, one side of which is provided with a plug-in slot, and the other side of which is bent to form a first clamping plate;

[0009] A second plug-in plate, one side of which has a plug-in portion plugged into the plug-in slot, and the other side of which is bent to form a second clamping plate opposite to the first clamping plate;

[0010] And, an adjusting member is arranged on the second plug board and connected to the first plug board, and the adjusting member can drive the first plug board to be close to or away from the second plug board.

[0011] Optionally, the second plug-in board has a mounting portion, one end of the adjusting member is rotatably connected to the mounting portion, and the other end is threadedly connected to the first plug-in board.

[0012] Optionally, the first plug board has an adjusting portion, the adjusting portion is arranged opposite to the mounting portion, and one end of the adjusting member away from the mounting portion is threadedly connected to the adjusting portion.

[0013] Optionally, the adjusting portion extends along a direction in which the first plug-in board and the second plug-in board are plugged in, and a threaded hole threadably connected to the adjusting member is provided along the extending direction of the adjusting portion.

[0014] Optionally, the adjusting member is an adjusting bolt, and the head of the adjusting bolt is embedded in the mounting portion and rotatably connected to the mounting portion.

[0015] Optionally, the plug-in slot extends along the length direction of the first plug-in board.

[0016] Optionally, the edges of the opening of the plug slot and the insertion portion of the plug portion are both rounded.

[0017] Optionally, the first plug board is bent to form the first clamping plate at a bending angle less than 90°;

[0018] And / or, the bending angle of the second plug board to form the second clamping plate is less than 90°.

[0019] Optionally, the thickness of the first clamping plate at a side close to the first plug-in board is greater than the thickness of the first clamping plate at a side away from the first plug-in board;

[0020] And / or, the thickness of the second clamping plate at a side close to the second plug-in board is greater than the thickness of the second clamping plate at a side away from the second plug-in board.

[0021] In a second aspect, the utility model also provides a surgical robot, further comprising:

[0022] Robotic arm;

[0023] And, the stamp fixture as described in any one of the first aspects is detachably connected to the robotic arm.

[0024] Beneficial effects of the utility model:

[0025] In the first aspect, by providing a first plug-in plate and a second plug-in plate that are plugged into each other, during installation, it is only necessary to insert the plug-in portion into the plug-in slot so that the first clamp and the second clamp are opposite and the first clamp is locked by the adjusting member, so that a space for accommodating the impression material can be formed. When the impression fixture needs to be disassembled, since the impression material has been solidified, it is only necessary to operate the adjusting member to drive the first plug-in plate away from the second plug-in plate to expand the space for accommodating the impression material, so that the clamp and the impression material can be squeezed into contact, and the clamp can be easily removed. In this way, when the impression fixture is removed from the patient's teeth, the spacing between the first clamp and the second clamp can be increased by the adjusting member, so as to release the squeezing force between the two and the impression material, so that it is not necessary to apply a large external force when removing the impression fixture, thereby reducing the pulling force on the patient's teeth and effectively reducing the possibility of causing damage to the patient's loose teeth.

[0026] Secondly, when in use, the surgical robot can place the impression fixture containing the impression material on the patient's teeth. When the impression material solidifies, the impression fixture can be opened to release the extrusion of the corresponding material of the impression fixture, so that the impression fixture can be quickly and easily removed, reducing the possibility of damage to the patient's loose teeth.

[0035] The utility model embodiment discloses a mold clamp and a surgical robot.

[0036] Reference Figure 1 and Figure 2 The die clamp comprises a first plug-in board 1, a second plug-in board 2 and an adjusting member 3. The first plug-in board 1 has a plug-in slot 11 on one side, and the other side is bent to form a first clamping plate 12; the second plug-in board 2 has a plug-in portion 21 plugged into the plug-in slot 11 on one side, and the other side is bent to form a second clamping plate 22 opposite to the first clamping plate 12; the adjusting member 3 is arranged on the second plug-in board 2 and connected to the first plug-in board 1, and the adjusting member 3 can drive the first plug-in board 1 to approach or move away from the second plug-in board 2.

[0037] Specifically, the first plug-in board 1 is in the shape of an elongated strip, and one of the two sides along the width direction thereof is concave on one side to form a plug-in slot 11. The plug-in slots 11 may be spaced apart and distributed in a plurality along the length direction of the first plug-in board 1, and each plug-in slot 11 may be plugged with a plug-in portion 21, or only one plug-in slot 11 may be provided. The first plug-in board 1 is bent upward or downward on one side away from the plug-in slot 11 to form a first clamping plate 12, and the first clamping plate 12 and the first plug-in board 1 are arranged in an L shape. Similarly, the second plug-in board 2 and the second clamping plate 22 are also arranged in an L shape, and the plug-in portion 21 may be an integrated structure with the second plug-in board 2 to facilitate production and processing. A space for accommodating the impression material is formed between the first clamping plate 12 and the second clamping plate 22, and one side of the space is closed by the plug-in portion 21 inserted into the plug-in slot 11, and the other side is opened to be inserted on the patient's teeth.

[0038] The adjusting member 3 is arranged on the side of the second plug board 2 away from the second clamping plate 22, and can be connected to the first plug board 1. The connection method can be snap-on, threaded connection, etc. It can drive the first plug board 1 to approach or move away from the second plug board 2, and can lock the first plug board 1 at multiple positions, so as to fix the first plug board 1 and the second plug board 2 together at any distance.

[0039] By setting the first plug-in board 1 and the second plug-in board 2 that are plugged into each other, when installing, it is only necessary to insert the plug-in portion 21 into the plug-in slot 11, so that the first clamp 12 and the second clamp 22 are opposite and the first clamp 1 is locked by the adjusting member 3, so that a space for accommodating the impression material can be formed. When the impression fixture needs to be disassembled, since the impression material has been solidified, it is only necessary to operate the adjusting member 3 to drive the first plug-in board 1 away from the second plug-in board 2 to expand the space for accommodating the impression material, so that the squeezing force between the clamp and the impression material can be released, and the clamp can be easily removed. In this way, when the impression fixture is removed from the patient's teeth, the spacing between the first clamp 12 and the second clamp 22 can be increased by the adjusting member 3, so as to release the squeezing force between the two and the impression material, so that it is no longer necessary to apply a large external force when removing the impression fixture, thereby reducing the pulling force on the patient's teeth and effectively reducing the possibility of causing damage to the patient's loose teeth.

[0040] Optionally, the second plug-in board 2 has a mounting portion 23 , one end of the adjusting member 3 is rotatably connected to the mounting portion 23 , and the other end is threadedly connected to the first plug-in board 1 .

[0041] Specifically, a mounting portion 23 is provided on the bottom wall of the second plug-in board 2, and the two can be an integrated structure to ensure that the overall connection strength is high. The adjusting member 3 can be a structure such as a screw or a screw, one end of which is rotatably connected to the mounting portion 23, and the other end is passed through the first plug-in board 1 and threadedly connected to the first plug-in board 1. It should be understood that the adjusting member 3 can also be rotatably connected to the first plug-in board 1 and threadedly connected to the second plug-in board 2, which can smoothly drive the first plug-in board 1 and the second plug-in board 2 to move closer to or away from each other.

[0042] By setting the mounting portion 23, one end of the adjusting member 3 is protruded and set outside the second plug-in board 2, so that the operator can easily screw the adjusting member 3. By simply screwing, the first plug-in board 1 can be driven away from the second plug-in board 2, thereby quickly separating the first clamping plate 12 from the second clamping plate 22.

[0043] Optionally, the first plug board 1 has an adjusting portion 13 , which is arranged opposite to the mounting portion 23 , and one end of the adjusting member 3 away from the mounting portion 23 is threadedly connected to the adjusting portion 13 .

[0044] Specifically, an adjusting portion 13 is provided on the bottom wall of the first plug board 1. The adjusting portion 13 is provided corresponding to the mounting portion 23. The adjusting portion 13 and the first plug-in portion 21 can be an integrated structure to ensure a high connection strength between the two. A threaded hole is provided through the adjusting portion 13, and the adjusting member 3 is threadedly connected in the threaded hole.

[0045] By providing the adjusting portion 13 , when the adjusting member 3 rotates, the first plug-in board 1 can be driven away from the second plug-in board 2 by utilizing the threaded connection with the adjusting portion 13 .

[0046] Optionally, the adjusting portion 13 extends along the direction in which the first plug-in board 1 and the second plug-in board 2 are plugged in, and a threaded hole threadedly connected to the adjusting member 3 is provided through the extending direction of the adjusting portion 13 .

[0047] Specifically, the length of the adjustment portion 13 can be equal to the width of the first plug-in board 1, or can be greater than the width of the first plug-in board 1. By extending the adjustment portion 13 along the plug-in direction of the two so that the length of the threaded hole provided therethrough is sufficient, the movement range of the adjustment portion 13 and the first plug-in board 1 driven by rotating the adjustment member 3 is large enough to be applicable to various different scenarios, thereby effectively improving the overall adaptability of the die clamp.

[0048] Optionally, the adjusting member 3 is an adjusting bolt, and the head of the adjusting bolt is embedded in the mounting portion 23 and rotatably connected to the mounting portion 23 .

[0049] Specifically, a mounting groove is provided on the top wall of the mounting portion 23, and the head of the adjusting bolt is at least partially or completely embedded in the mounting groove. In order to reduce the friction force on the adjusting bolt, the mounting groove can be designed to be open, that is, the upper part of the mounting groove is open, and only the lower side of the head of the adjusting bolt is rotatably connected in the mounting groove, so as to reduce the contact area between the adjusting bolt and the mounting groove, thereby achieving the effect of reducing the friction force on the adjusting bolt.

[0050] By opening a mounting groove on the mounting portion 23, the head of the adjusting bolt can be embedded in the mounting groove and can form a snap connection with the side wall of the mounting groove, thereby realizing the snap connection limit between the mounting portion 23 and the adjusting bolt, and ensuring that the adjusting bolt can rotate on its own. There is no need to set up additional limiting structures such as bearings to limit the position of the conditional bolt, which effectively simplifies the structural complexity of the die fixture and helps to reduce the overall production difficulty.

[0051] Optionally, the plugging slot 11 extends along the length direction of the first plugging board 1 .

[0052] Specifically, only one plug-in slot 11 is provided, and it penetrates the first plug-in board 1 along the length direction of the first plug-in board 1, and the plug-in portion 21 is adapted to the shape and size of the plug-in slot 11, so that the plug-in portion 21 can completely fill the plug-in slot 11, thereby making full contact between the first plug-in board 1 and the second plug-in board 2, ensuring that the two can form a stable connection.

[0053] Optionally, the edges of the opening of the plug slot 11 and the insertion portion of the plug portion 21 are both rounded.

[0054] Specifically, the rounded corners increase the connection area at the opening of the plug-in slot 11, while reducing the cross-sectional area of ​​the insertion point of the plug-in board, which is beneficial for the plug-in portion 21 to maintain correspondence with the plug-in slot 11. In addition, the arc surface formed by the rounded corners can also provide a certain guiding effect during insertion, thereby ensuring that the plug-in portion 21 can be smoothly inserted into the plug-in slot 11.

[0055] Optionally, the first plug-in board 1 is bent to form the first clamping plate 12 at a bending angle less than 90°. The second plug-in board 2 is bent to form the second clamping plate 22 at a bending angle less than 90°.

[0056] Specifically, the angle between the first clamping plate 12 and the first plug-in board 1 is greater than 90°, so that the first clamping plate 12 extends obliquely, thereby making the space opening formed with the second clamping plate 22 larger, so as to facilitate matching with the patient's teeth. Similarly, the angle between the second clamping plate 22 and the second plug-in board 2 is also greater than 90°, which can further increase the opening of the space.

[0057] Optionally, the thickness of the first splint 12 close to the first plug board 1 is greater than the thickness of the first splint 12 away from the first plug board 1; the thickness of the second splint 22 close to the second plug board 2 is greater than the thickness of the second splint 22 away from the second plug board 2.

[0058] Specifically, the thickness of the first splint 12 decreases from the side close to the first plug-in board 1 to the side away from the first plug-in board 1, so that one side of the first splint 12 is thicker and the other side is thinner, thereby further increasing the connecting area at the opening of the space to further facilitate the plug-in fit with the patient's teeth.

[0059] The surgical robot comprises a mechanical arm and the die clamp in the above embodiment. The die clamp is detachably connected to the mechanical arm.

[0060] When in use, the surgical robot can place the impression fixture containing the impression material on the patient's teeth. When the impression material solidifies, the impression fixture can be opened to release the extrusion of the corresponding material of the impression fixture, so that the impression fixture can be quickly and easily removed, reducing the possibility of damage to the patient's loose teeth.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
