Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a quick-disassembly and assembly type safety rope for an implant screwdriver. Background Art

[0002] An implant screwdriver refers to a medical device used in oral clinical diagnosis and treatment. It is used to separate or connect abutments, covering screws, carriers, etc. after implanting implants. When implanting and wearing a prosthesis, a torque wrench is usually used together to apply torque to the abutment screw.

[0003] In oral clinical operations, the supine position is usually adopted, and the patient is required to be in a wide-open mouth state. If no relevant preventive measures are taken, under the action of gravity, once the slipped implant screwdriver falls into the patient's mouth, there is a possibility of accidental swallowing or aspiration. Compared with aspiration, accidental swallowing is more common, and the risk brought by aspiration is higher.

[0004] Currently, in order to avoid the problem of the implant screwdriver falling off, some safety anti-detachment structures are usually provided, such as a safety rope. When in use, one end of the safety rope is connected to the implant screwdriver, and the other end of the safety rope forms anti-detachment protection for the implant screwdriver by pulling or fixing it on the arm. However, in this way, it is easy for the safety rope to become entangled during the rotation of the implant screwdriver, thus affecting the use of the implant screwdriver. Summary of the Invention

[0005] The purpose of the present invention is to provide a quick-disassembly and assembly type safety rope for an implant screwdriver, so as to solve the problem in the prior art that when providing anti-detachment protection for the implant screwdriver, the connecting rope is prone to rotate and wind during the rotation of the implant screwdriver.

[0024] Embodiment

[0025] As Figures 1 to 4 shown, the embodiment of the present invention provides a quick-disassembly type planting screwdriver safety rope, which includes a fixed sleeve 1, a connection component 2, a snap ring 3, a rope body 4 and a wearing part 5; an annular card slot 11 is opened on the outer circumferential wall of the fixed sleeve 1; the connection component 2 is arranged on the fixed sleeve 1 and is used for detachably connecting the fixed sleeve 1 and the planting screwdriver after the fixed sleeve 1 is sleeved on the planting screwdriver; the snap ring 3 is rotatably connected in the annular card slot 11; one end of the rope body 4 is connected to the outer wall of the snap ring 3; the wearing part 5 is connected to the other end of the rope body 4 and is used for wearing on the human arm.

[0026] Among them, the wearing part 5 is a conventional structure such as a bracelet that can be fixed on the arm.

[0027] In this embodiment, before using the implant screwdriver, the fixing sleeve 1 is detachably fixed on the rod body of the implant screwdriver through the connecting component 2, and then the wearing part 5 is fixed on the human arm. Since the fixing sleeve 1 and the wearing part 5 are connected by the snap ring 3 and the rope body 4, when installing the implant accessories (including but not limited to the covering screw, the central screw, the healing abutment, the temporary abutment, the repair abutment) with the implant screwdriver, it can form an anti-detachment effect on the implant screwdriver. And because the snap ring 3 is rotatably connected with the annular groove 11 on the outer wall of the fixing sleeve 1, when rotating the implant screwdriver, the fixing sleeve 1 can rotate with the implant screwdriver, while the snap ring 3 will not rotate with the implant screwdriver, thus avoiding the problem of the rope body 4 being entangled.

[0028] Specifically, the connecting component 2 includes a mounting seat 21, a plurality of flap claws 22 and a pressing block 23; the mounting seat 21 is cylindrical, the outer diameter of the mounting seat 21 is smaller than the inner diameter of the fixing sleeve 1, the outer circumferential wall of the mounting seat 21 is provided with an external thread 211, and the upper circumferential inner wall of the fixing sleeve 1 is provided with an internal thread 12 matching the external thread 211; a plurality of flap claws 22 are fixedly arranged around the lower end of the mounting seat 21, and each flap claw 22 is made of an elastic material; the pressing block 23 is sleeved and fixed on the lower inner wall of the fixing sleeve 1, and a tapered hole 231 for the implant screwdriver to pass through is opened in the middle of the pressing block 23, and the large-diameter end of the tapered hole 231 is arranged towards the side of the internal thread 12.

[0029] When connecting through the connecting component 2, first sleeved the mounting seat 21 on the planting screwdriver, and made the planting screwdriver pass through the inside of multiple petal claws 22. Then, sleeved the fixing sleeve 1 on the planting screwdriver from below the mounting seat 21, so that the planting screwdriver passed through the tapered hole 231. Move the fixing sleeve 1 upward until the internal thread 12 contacts the external thread 211. At this time, keep the mounting seat 21 itself stationary and turn the fixing sleeve 1. Thus, through the cooperation of the internal thread 12 and the external thread 211, the fixing sleeve 1 is threadedly connected to the outside of the mounting seat 21. When threadedly connected, the fixing sleeve 1 will gradually move upward, thereby driving the tapered hole 231 on the extrusion block 23 to squeeze the multiple petal claws 22 inward and bend them. Thus, the multiple petal claws 22 are used to clamp and fix the whole of the mounting seat 21 and the fixing sleeve 1 on the rod body of the planting screwdriver, so as to keep the whole rotating following the planting screwdriver. When the planting operation is completed and it is necessary to remove it from the planting screwdriver, reverse-rotate the fixing sleeve 1 to make the fixing sleeve 1 move downward, so that the tapered hole 231 on the extrusion block 23 no longer squeezes the multiple petal claws 22. Since the multiple petal claws 22 are made of elastic material, they will automatically return to their original state, thus no longer clamping the rod body of the planting screwdriver, and making the whole of the mounting seat 21 and the fixing sleeve 1 fall off from the planting screwdriver. Then continue to rotate the fixing sleeve 1 to separate the fixing sleeve 1 from the mounting seat 21. The whole assembly and disassembly process is relatively convenient and is convenient for repeated use after subsequent disinfection.

[0030] Furthermore, in order to limit the position of the spiral movement of the fixing sleeve 1, a limiting ring 6 is coaxially fixed at the upper end of the mounting seat 21. Through the provided limiting ring 6, the upper end of the fixing sleeve 1 can be abutted and limited. It can not only prevent the fixing sleeve 1 from being screwed too much and detaching from the mounting seat 21, but also ensure that when the upper end of the fixing sleeve 1 abuts against the limiting ring 6, the tapered hole 231 on the extrusion block 23 completely squeezes and deforms the multiple petal claws 22, so as to be firmly fixed on the planting screwdriver. At the same time, the limiting ring 6 can also serve as the exposed fixing part of the mounting seat 21, which is convenient to keep the mounting seat 21 itself in a non-rotating state by holding the limiting ring 6, so as to facilitate rotating the fixing sleeve 1 to threadedly connect it with the mounting seat 21.

[0031] Furthermore, in order to prevent the limiting ring 6 from slipping, the outer wall of the limiting ring 6 is polygonal.

[0032] Furthermore, in order to facilitate rotating the fixing sleeve 1, a screwing part 7 is provided on the outer wall of the upper end of the fixing sleeve 1. The screwing part 7 is a rotating sleeve. The inner wall of the rotating sleeve is sleeved and fixed with the outer wall of the upper end of the fixing sleeve 1, and the outer wall of the rotating sleeve is hexagonal.

[0033] Further, in order to improve the self-locking ability of the internal thread 12 and the external thread 211, when the plurality of flap claws 22 are inwardly squeezed and bent through the tapered holes 231 in the extrusion block 23, the reaction force generated by the plurality of flap claws 22 is resisted. Therefore, both the internal thread 12 and the external thread 211 are provided as trapezoidal threads or tapered threads.

[0034] Further, in order to reduce the friction between the snap ring 3 and the annular groove 11, the snap ring 3 and the annular groove 11 are rotatably connected through a bearing 8.

[0035] Further, for the convenience of connection, a connecting ear plate 91 is fixed on the outer wall of the snap ring 3, a connecting hole 911 is provided in the connecting ear plate 91, and a connecting ring 92 is fixed at one end of the rope body 4. The connecting ring 92 is inserted into the connecting hole 911.

[0036] Furthermore, in order to prevent the inner wall of the connecting ring 92 from being easily worn by the edge of the hole wall of the connecting hole 911 when the connecting ring 92 is connected to the connecting hole 911, the hole wall of the connecting hole 911 is set to be arc-shaped and convex inward.

[0037] In summary, through the cooperation of the fixed sleeve, the connecting component, the snap ring, the rope body and the wearing part provided by the present invention, when the implant is installed into the drill hole opened in the alveolar bone by the implant screwdriver, an anti-detachment effect on the implant screwdriver can be formed. And because the snap ring and the annular groove on the outer wall of the fixed sleeve are rotatably connected, when the implant screwdriver is rotated, the fixed sleeve can follow the implant screwdriver to rotate, while the snap ring will not follow the implant screwdriver to rotate, thus avoiding the problem of the rope body being entangled. And the fixed sleeve is detachably fixed on the rod body of the implant screwdriver through the connecting component for disassembly, which is convenient for subsequent disinfection and repeated use.

[0038] The above-disclosed are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
