Description

Technical Field

[0001] The present application relates to the technical field of oral equipment, and in particular provides a mounting sleeve and a driving device. Background Art

[0002] For intraoral implantation in edentulous jaws, most people currently use traditional impression-taking technology and digital impression scanning and scanning rod technology; traditional impression-taking technology has cumbersome steps and is time-consuming, while digital impression scanning and scanning rod technology uses a scanner to identify landmark points on the scanning rod, and through the splicing of landmark points, impression taking is faster and the data is more intuitive, thereby improving the accuracy of implant impression taking.

[0003] In digital impression scanner scanning, the scanner is fixed to the implant base inside the mouth with screws. Existing scanners are often installed manually, requiring the operator to hold the scanner with one hand and tighten the screws with a screwdriver or power tool in the other. Due to the limited space in the mouth, this installation method is difficult to perform manually. Furthermore, the scanner is prone to unstable positioning during installation, resulting in installation errors and hindering accurate positioning. Utility Model Content

[0004] The purpose of the embodiment of the present application is to provide a mounting sleeve, which aims to solve the problem that the existing scanning rod is difficult to operate during the installation process; and the scanning rod limit is unstable, resulting in installation errors.

[0005] To achieve the above objectives, the technical solution adopted in this application is:

[0006] In the first aspect, an embodiment of the present application provides a mounting sleeve for being mounted on the head of a wrench and for limiting the position of a scanning rod, wherein the mounting sleeve has a positioning hole that can be mounted on the scanning rod and a receiving cavity for accommodating the head, and the positioning hole is communicated with the receiving cavity; and a limiting portion is provided on the mounting sleeve, and the limiting portion is used to be connected to the scanning rod in a limiting manner.

[0007] In some embodiments, the limiting portion limits the scanning rod in the circumferential direction of the positioning hole.

[0008] By adopting the above technical solution, the limiting portion limits the circumferential position of the scanning rod to effectively limit the rotation of the scanning rod.

[0009] In some embodiments, the mounting sleeve has a first end and a second end relative to each other, the positioning hole forms an opening at the first end, and the limiting portion includes a bayonet provided at the first end; the scanning rod includes a main rod and a support rod provided on the main rod, and the axis of the main rod forms an angle with the axis of the support rod; the main rod is sleeved in the positioning hole, and the bayonet and the support rod are clamped along the axial direction of the main rod.

[0010] By adopting the above technical solution, the scanning rod has a support rod, and a bayonet is correspondingly provided at the first end of the mounting sleeve. When the main rod is inserted into the mounting sleeve, the support rod can abut against the inner wall of the bayonet to effectively limit the circumferential deflection of the main rod; at the same time, the bayonet is engaged with the support rod along the axial direction of the main rod, and the bayonet can limit the axial position of the scanning rod.

[0011] In some embodiments, there are multiple bayonet holes, and each bayonet hole is arranged at intervals along the circumferential direction at the first end.

[0012] By adopting the above technical solution and providing a plurality of bayonet holes, the installation angle of the scanning rod can be easily adjusted by connecting the support rod with the bayonet holes at different positions.

[0013] In some embodiments, the diameter of the bayonet gradually decreases from the first end to the second end.

[0014] By adopting the above technical solution, the diameter of the bayonet near the first end is larger, which is convenient for the support rod to be clamped in; the diameter of the bayonet away from the first end is smaller, which can effectively clamp the support rod.

[0015] In some embodiments, the single bayonet forms an interference fit with the support rod at least at a position of minimum diameter.

[0016] By adopting the above technical solution, the support rod can be connected to the bayonet.

[0017] In some embodiments, the wall thickness of the mounting sleeve gradually decreases from the first end to the second end.

[0018] By adopting the above technical solution, the mounting sleeve is provided with a bayonet at the first end to be engaged with the support rod. The wall thickness of the mounting sleeve at the first end is thicker to have better structural strength, and then the mounting sleeve can provide sufficient stress to the support rod to limit the deflection of the scanning rod and improve the structural stability; the mounting sleeve is engaged with the head near the second end, so the wall thickness of the mounting sleeve at this position is smaller, which is conducive to the close fit between the mounting sleeve and the head.

[0019] In some embodiments, a notch is provided at the second end to connect the accommodating cavity with the outside.

[0020] By adopting the above technical solution, the head is installed in the accommodating cavity, and the head protrudes upwardly out of the installation sleeve, and the limiting structure is stable.

[0021] In some embodiments, a through hole is provided on the outer wall of the mounting sleeve for the head to pass through the accommodating cavity.

[0022] By adopting the above technical solution, the installation sleeve can be flexibly deformed, and then the head can be inserted into the accommodating cavity through the perforation, so that the installation sleeve is tightly wrapped around the outside of the head.

[0023] In some embodiments, the mounting sleeve is flexible.

[0024] By adopting the above technical solution, the mounting sleeve is made of a flexible material and can be quickly and conveniently sleeved onto the outside of the head of the driving rod.

[0025] In the second aspect, an embodiment of the present application provides a driving device, including a wrench, a screwdriver and the mounting sleeve; the mounting sleeve is sleeved on the head of the wrench, the screwdriver is used to be installed on the head and extend into the positioning hole, and the wrench is used to drive the screwdriver to rotate around the axis; the scanning rod has a fixing part, and the screwdriver is used to screw the fixing part.

[0026] In some embodiments, the wrench includes a driving rod having a hand-held portion and a connecting portion, and the head is arranged at the end of the connecting portion; a through hole is provided on the outer wall of the mounting sleeve, and the head passes through the through hole and is interference fit in the accommodating cavity.

[0027] In some embodiments, the mounting sleeve is provided with a notch for allowing the head to pass through the accommodating cavity to the outside, and the notch is interference fit with the head.

[0028] The beneficial effects of the mounting sleeve and the driving device of the present application are as follows: the mounting sleeve can be sleeved on the wrench to form a driving device; by installing the scanning rod in the positioning hole of the mounting sleeve, the limiting part of the scanning rod limits the scanning rod, so that the relative position of the scanning rod and the mounting sleeve remains stable; the scanning rod is installed and fixed by driving the screwdriver to rotate and tightening the retaining part by the wrench, which effectively limits the deflection of the scanning rod during the installation process, has a stable structure, is conducive to reducing installation errors, and improves installation accuracy; and the installation method is easy and labor-saving.

[0050] For intraoral implants in edentulous jaws, most currently used are traditional impression-taking technology and digital impression scanner scanning and scanning rod technology; traditional impression-taking technology is cumbersome and time-consuming, while digital impression scanner scanning and scanning rod technology uses a scanner to identify landmarks on the scanning rod. By splicing the landmarks, impression-taking is faster and the data is more intuitive, which improves the accuracy of implant impression-taking. In the digital impression scanner scanning and scanning rod technology, the scanning rod needs to be fixed to the implant base in the oral cavity by screws; the scanning rod of the existing technology is often installed manually, and the operator needs to hold the scanning rod with one hand and use a screwdriver or power tool with the other hand to tighten the screws on the scanning rod to fix the scanning rod to the implant base; due to the limited space in the oral cavity, this installation method is not easy to operate manually. In addition, the scanning rod is prone to rotation during the installation process, resulting in installation errors, which is not conducive to installing the scanning rod in the predetermined position.

[0051] Based on this, in order to solve the above problems, the present application designs a mounting sleeve, which installs the scanning rod in the mounting sleeve and limits the scanning rod through the limiting part of the mounting sleeve, so that the relative position of the scanning rod and the mounting sleeve remains stable; the driving rod drives the screwdriver to rotate and screws the fixing part to install and fix the scanning rod, which effectively limits the deflection of the scanning rod during the installation process, has a stable structure, and is conducive to reducing installation errors and improving installation accuracy; and the installation method is easy and labor-saving.

[0052] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , an embodiment of the present application provides a driving device for positioning and installing a scanning rod 1; the driving device includes a wrench 2, a screwdriver 8 and a mounting sleeve 3; the mounting sleeve 3 is sleeved on the head 202 of the wrench 2; the screwdriver 8 is installed on the head 202, and the wrench 2 drives the screwdriver 8 to rotate around the axis; the mounting sleeve 3 can limit the circumferential position of the scanning rod 1, and the scanning rod 1 has a retaining member 5, and the screwdriver 8 is used to screw the retaining member 5.

[0053] Specifically, the screwdriver 8 is a screwdriver head, which refers to a screwdriver head installed on an electric tool such as a hand drill or an electric drill for tightening screws. The wrench 2 is a driving tool for driving the screwdriver 8 to rotate. Preferably, the wrench 2 is an electric wrench, and the screwdriver 8 is detachably connected to the head 202; the rotation of the screwdriver 8 can be automatically controlled by the wrench 2.

[0054] In some embodiments, the retaining member 5 is a screw, and the scanning rod 1 is connected to the installation object through the retaining member 5; for retaining members 5 of different sizes, a screwdriver 8 of corresponding models and specifications can be selected so that the screwdriver 8 can be connected to the retaining member 5 to screw the retaining member 5.

[0055] refer to Figure 4 、 Figure 5 、 Figure 6In some embodiments, the mounting sleeve 3 has a positioning hole 9 that can be socketed with the scanning rod 1 and a receiving cavity 302 for accommodating the head 202, and the positioning hole 9 is connected to the receiving cavity 302; and a limiting portion 4 is provided on the mounting sleeve 3, and the limiting portion 4 is used to be connected to the scanning rod 1 in a limiting manner.

[0056] Specifically, the scanning rod 1 is installed by the driving device as follows: the upper end of the driver 8 is connected to the head 202 in advance and the mounting sleeve 3 is mounted on the head 202, and the lower end of the driver 8 is extended into the positioning hole 9; then the scanning rod 1 is sleeved into the positioning hole 9 of the mounting sleeve 3, and the scanning rod 1 is limitedly connected to the limiting portion 4; the driver 8 and the retaining piece 5 on the scanning rod 1 are positioned and docked up and down; then the scanning rod 1 is placed in the oral cavity and the wrench 2 is controlled to drive the driver 8 to rotate to screw the retaining piece 5, and the installation of the scanning rod 1 in the oral cavity can be completed. The operation is easy, labor-saving, convenient and convenient.

[0057] In some embodiments, the limiting portion 4 limits the scanning rod 1 in the circumferential direction of the positioning hole 9 so that the relative positions of the scanning rod 1 and the mounting sleeve 3 in the circumferential direction remain relatively fixed; then, during the installation process of the scanning rod 1, the scanning rod 1 will not rotate with the screwing of the retaining member 5, and the structural position of the scanning rod 1 itself remains stable, which is conducive to reducing installation errors and improving installation accuracy.

[0058] The specific limiting connection relationship between the limiting portion 4 and the scanning rod 1 can be, but is not limited to, snap connection, plug connection, bonding, etc., so as to ensure that the limiting portion 4 can circumferentially limit the scanning rod 1.

[0059] For example, the limiting portion 4 may include a bayonet 7 provided on the mounting sleeve 3. When the scanning rod 1 is sleeved with the mounting sleeve 3, the scanning rod 1 engages with the bayonet 7 through its own structure or an additional engaging structure to limit the deflection of the scanning rod 1. Alternatively, the limiting portion 4 may include a protrusion provided in the mounting sleeve 3. When the scanning rod 1 is sleeved with the mounting sleeve 3, the protrusion and the scanning rod 1 have an interference fit to limit the deflection of the scanning rod 1.

[0060] The mounting sleeve 3 of the present application can be sleeved on the wrench 2 to form a driving device; by installing the scanning rod 1 in the positioning hole 9 of the mounting sleeve 3, the limiting part 4 of the scanning rod 1 circumferentially limits the scanning rod 1, so that the scanning rod 1 and the mounting sleeve 3 remain circumferentially fixed; the wrench 2 drives the screwdriver 8 to rotate and screws the retaining part 5 to install and fix the scanning rod 1, effectively limiting the deflection of the scanning rod 1 during the installation process, and the structure is stable, which is conducive to reducing installation errors and improving installation accuracy; and the installation method is easy and labor-saving.

[0061] refer to Figure 4-Figure 7In some embodiments, the mounting sleeve 3 has a first end 6 and a second end 11 relative to each other, the positioning hole 9 forms an opening 301 at the first end 6, the limiting portion 4 includes a bayonet 7 provided at the first end 6, and the bayonet 7 is connected to the positioning hole 9; the scanning rod 1 includes a main rod 101 and a support rod 102 provided on the main rod 101, and the axis of the main rod 101 forms an angle with the axis of the support rod 102; the main rod 101 is used to be sleeved in the positioning hole 9, and the retaining member 5 is provided on the main rod 101; the bayonet 7 is used to be clamped with the support rod 102 along the axial direction of the main rod 101.

[0062] Specifically, the main rod 101 is sleeved in the positioning hole 9, and the retaining member 5 is provided on the main rod 101. The bayonet 7 is formed with an opening 301 at the first end 6. When the main rod 101 is sleeved in the installation sleeve 3, the support rod 102 can be clamped into the bayonet 7. The support rod 102 can abut against the side wall of the bayonet 7 to effectively limit the circumferential deflection of the main rod 101; then, during the rotation process of the screwdriver 8 screwing the retaining member 5, the retaining member 5 rotates relative to the scanning rod 1, and the scanning rod 1 and the installation sleeve 3 maintain a relatively fixed position in the circumferential direction; at the same time, the bayonet 7 is used to clamp with the support rod 102 along the axial direction of the main rod 101, and then the installation sleeve 3 limits the scanning rod 1 in the axial direction of the main rod 101, so that the structure of the scanning rod 1 remains stable and the installation error is reduced.

[0063] In some embodiments, the support rod 102 is arranged perpendicularly relative to the main rod 101. That is, the main rod 101 extends in the vertical direction, and the support rod 102 extends in the horizontal direction, and the support rod 102 can be engaged with the bayonet 7 to limit position.

[0064] refer to Figure 5 、 Figure 6 、 Figure 7 In some embodiments, there are multiple bayonet holes 7 , and each bayonet hole 7 is arranged at intervals along the circumferential direction at the first end 6 .

[0065] It can be understood that by providing a plurality of bayonet sockets 7 and engaging the support rod 102 with bayonet sockets 7 at different positions, the installation angle of the scanning rod 1 in the oral cavity can be easily adjusted, thereby improving installation accuracy and efficiency.

[0066] refer to Figure 2 、 Figure 5 In some embodiments, the diameter of the bayonet 7 gradually decreases from the first end 6 to the second end 11 .

[0067] It can be understood that the caliber of the bayonet 7 is designed to be gradient along the axial direction of the positioning hole 9; the caliber of the bayonet 7 near the first end 6 is larger, while the caliber of the bayonet 7 away from the first end 6 is smaller, which facilitates the smooth insertion of the support rod 102.

[0068] In some embodiments, a single bayonet 7 forms an interference fit with the support rod 102 at least at the position of the minimum diameter, and then the support rod 102 can be clamped in the bayonet 7, thereby connecting the mounting sleeve 3 with the scanning rod 1, so that the mounting sleeve 3 and the support rod 102 can form a limit in the circumferential direction of the positioning hole 9, and the mounting sleeve 3 and the support rod 102 are firmly connected.

[0069] refer to Figure 4 In some embodiments, the wall thickness of the mounting sleeve 3 gradually decreases from the first end 6 to the second end 11 .

[0070] As will be understood, the mounting sleeve 3 has a bayonet 7 at the first end 6 for engaging with the support rod 102. To enhance structural stability after engagement, the mounting sleeve 3 has a thicker wall at the first end 6 to provide greater structural strength. This allows the mounting sleeve 3 to provide sufficient stress on the support rod 102 to limit deflection of the scanning rod 1, thereby enhancing structural stability. The mounting sleeve 3 is designed to engage with the head 202 near the second end 11, so the wall thickness of the mounting sleeve 3 at this location is smaller, facilitating a close fit between the mounting sleeve 3 and the head 202.

[0071] In some embodiments, the installation sleeve 3 is provided with a notch 10 at the second end 11 to connect the accommodating cavity 302 with the outside.

[0072] refer to Figure 2 、 Figure 4 For example, the head 202 is installed in the accommodating cavity 302, and the top of the head 202 will pass through the notch 10 to the outside of the mounting sleeve 3. In some embodiments, the notch 10 and the head 202 are interference fit so that the mounting sleeve 3 and the head 202 are tightly covered.

[0073] refer to Figure 1 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 9 In some embodiments, a through hole 303 is provided on the outer wall of the mounting sleeve 3 for the head 202 to penetrate into the accommodating cavity 302 .

[0074] Specifically, the installation sleeve 3 is detachably connected to the head 202 , and the head 202 is inserted into the accommodating cavity 302 of the installation sleeve 3 through the through hole 303 , and the installation sleeve 3 is covered on the surface of the head 202 .

[0075] In some embodiments, the wrench 2 includes a driving rod 201 having a grip portion 2011 and a connecting portion 2012 , with a head 202 disposed at the end of the connecting portion 2012 ; the head 202 passes through the through hole 303 and is interference fit in the accommodating cavity 302 .

[0076] It is understood that the handle portion 2011 is convenient for an operator to hold and operate, and the connecting portion 2012 is disposed between the head portion 202 and the handle portion 2011, with the head portion 202 disposed at the end of the connecting portion 2012. The handle portion 2011 and the connecting portion 2012 may extend in the same direction; the handle portion 2011 and the connecting portion 2012 may also form an angle therebetween, which is not specifically limited herein.

[0077] In some embodiments, the mounting sleeve 3 is flexible.

[0078] Specifically, the mounting sleeve 3 is made of a flexible material, and the material of the mounting sleeve 3 includes at least one of silicone, rubber and plastic; the mounting sleeve 3 can undergo flexible deformation, and then the head 202 can pass through the through hole 303 and be arranged in the accommodating cavity 302, and the mounting sleeve 3 tightly covers the outside of the head 202, effectively preventing the head 202 from falling out.

[0079] Continue to refer Figure 4 In some embodiments, at least one of any two opposite ends of the head 202 protrudes outward from the connecting portion 2012 , and the protruding portion forms an angle with the connecting portion 2012 .

[0080] In some embodiments, both opposite ends of the head 202 protrude outward from the driving rod 201 in a direction perpendicular to the driving rod 201. After the head 202 is sleeved with the mounting sleeve 3, the top end of the head 202 will partially pass through the notch 10 to the outside of the mounting sleeve 3. The notch 10 and the head 202 have an interference fit, so that the mounting sleeve 3 and the head 202 are tightly covered, and the distance between the opposite ends of the head 202 is greater than the diameter of the through hole 303, thereby making it difficult for the head 202 to escape from the through hole 303.

[0081] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
