Description

Technical Field

[0001] This utility model relates to the field of implantation nail auxiliary technology, specifically to an implantation nail installation and retention device. Background Technology

[0002] The application of implants is becoming increasingly widespread in medical and some industrial fields. For example, in orthopedic surgery, implants are often used to fix fracture sites and aid bone healing; in dentistry, implants provide stable support for dentures. In industry, certain materials requiring high-strength connections also use similar fixation methods. Traditional implant installation methods often rely on the experience of the dentist or operator and the stability of manual operation. In the surgical environment, when installing orthopedic implants, dentists use tools such as screwdrivers to screw the implants into the bone, making it difficult to precisely control the angle and depth of the implant. Due to the hardness and complex internal structure of bone, manual operation may cause the implant to deviate from its intended position, thus affecting the fixation effect and potentially damaging surrounding tissues and nerves. Similar problems exist in dental implant placement; angular deviations may affect the installation and long-term stability of dentures. Therefore, retention devices are needed to assist in the implantation of implants.

[0003] In response, Chinese patent application number CN202322447289.9 discloses an implantation device for assisting implantation of a nail. The device includes a cuboid-shaped auxiliary block, an inlet hole and an auxiliary ruler structure disposed on the auxiliary block. The upper surface of the auxiliary block is an inlet surface and the lower surface is a contact surface. The first end of the inlet hole is located on the inlet surface and the second end is located on the contact surface. The inlet hole is an inclined hole, and the axis of the guide hole has a set angle with the inlet surface and the contact surface. The auxiliary ruler structure is disposed on the inlet surface, and the center of the auxiliary ruler structure coincides with the center of the second end of the inlet hole in a direction perpendicular to the inlet surface and the contact surface.

[0004] However, existing implantation nail assist devices are inconvenient to adjust and support according to usage needs, which affects the effectiveness of use;

[0005] Therefore, in order to solve the above problems, an implanted nail installation and retention device is proposed. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 One embodiment provided by this utility model:

[0025] An implant nail installation and retention device includes a support base 100. An assembly screw 110 is mounted on the upper part between two sets of support bases 100. An assembly screw cylinder 120 is threadedly sleeved in the middle of the assembly screw 110. An assembly sleeve 130 is sleeved on the outside of the assembly screw cylinder 120 through a bearing. A lifting frame 140 is mounted on the bottom center of the assembly sleeve 130. A support sleeve 141 is integrally fixed at the bottom of the lifting frame 140.

[0026] As described in more detail in this embodiment, a support column 101 is fixedly provided at the center of the lower part of the support base 100. Side support frames 102 are mounted on both sides of the support column 101, and the upper end of the side support frames 102 is supported at the bottom of the support base 100. A support foot 150 is mounted at the bottom of the support column 101, and an inner telescopic rod 151 is fixed at the top of the support foot 150. The inner telescopic rod 151 is inserted through the support column 101. A locking pin 152 is threaded into the lower rear side of the support column 101, and the inner end of the locking pin 152 abuts against the outer wall of the inner telescopic rod 151. During assembly and use, the support of the support foot 150 facilitates the adjustment and support of the support column 101, making it easy to mount across it and making auxiliary use more convenient.

[0027] As described in more detail in this embodiment, the support sleeve 141 is cylindrical, and an insertion hole 142 is provided inside the support sleeve 141. In use, the nailing tool and nail are inserted through the support sleeve 141 and the insertion hole 142. By adjusting the angle between the support sleeve 141 and the hanging frame 140, the implantation assistance can be made to meet the relevant requirements, making the operation and use more convenient.

[0028] As described in more detail in this embodiment, limit nuts 121 are provided on both sides of the assembly screw cylinder 120, and the limit nuts 121 are threaded onto the outer wall of the assembly screw 110. Limit pins 131 are threaded into the outer walls of both ends of the assembly screw cylinder 130, and the inner ends of the limit pins 131 abut against the outer wall of the assembly screw cylinder 120. The cross-sections of the two side walls of the assembly screw cylinder 120 are regular polygons, and the cross-sections of the two end sections of the assembly screw cylinder 120 are hexagonal. During assembly and use, after being supported by the support base 100 and spanning across it, the screws of the corresponding assembly screws 110... Then, rotate the assembly screw 120 to move it to the appropriate position, and tighten the limit nut 121 to limit the assembly screw 120. Further, rotate the assembly sleeve 130 and tighten it with the limit nut 131 to limit the assembly sleeve 130. This makes it easier for the assembly sleeve 130 to support and maintain the relevant angle of the lifting frame 140, making the support assembly of the support sleeve 141 and the through hole 142 more convenient. Then, it is easier to assist it through the support sleeve 141 and the through hole 142.

[0029] Working principle: During assembly and use, the support base 150 and the inner telescopic rod 151 cooperate to support the support column 101. Then, tightening the locking pin 152 limits the movement of the inner telescopic rod 151 and the support column 101, thus assisting in supporting the support base 100. This allows the support base 100 to easily support the assembly screw 110, which spans over the external area above the subsequent insertion point. Furthermore, rotating the assembly screw cylinder 120, with the engagement of the threads, facilitates its rotation and movement. After moving to the appropriate position... Tighten the limiting nut 121 to provide limiting support for the assembly cylinder 120. Then rotate the assembly cylinder 130 so that it drives the lifting frame 140 to a suitable angle. Tighten the limiting nut 131 to provide limiting support for the assembly cylinder 130 and to support and maintain the support sleeve 141 and the through hole 142. This allows tools and nails to be inserted through the through hole 142, ensuring a relatively fixed angle during implantation. This makes implantation and installation more convenient and stable. The operation is now complete.
