Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a simple broken nail remover. Background Technology

[0002] In the medical field, especially in orthopedic surgery, using metal fixators such as pins to immobilize fracture sites is a common and effective treatment method. However, over time, due to patient activity, quality issues with the metal fixator itself, or other factors, pins may break. If these broken pins (referred to as "broken pins") are not removed promptly, they may adversely affect the patient's quality of life and rehabilitation.

[0003] A search revealed a universal broken nail extractor in publication number CN209474786U. This utility model discloses a universal broken nail extractor, comprising a drill rod body and a handle. The upper part of the drill rod body is a solid section, and the lower part is a hollow section. The outer side of the lower part of the drill rod body is provided with a tapered adjustment section that is smaller at the top and larger at the bottom. The tapered adjustment section has external threads, and an adjustment ring is fitted onto the tapered adjustment section. The adjustment ring has internal threads that mate with the external threads of the tapered adjustment section. Above the tapered adjustment section is a transition section, and below the tapered adjustment section is a drill sleeve section. The hollow section of the lower part of the drill rod body has three open slots distributed along its circumference, with the open slots starting from the transition section and extending to the bottom of the drill rod body.

[0004] The aforementioned broken screw extractor is easy to operate. By rotating the adjusting ring according to the actual size of the bone screw, its position on the conical adjusting section is adjusted, changing the inner diameter of the drill sleeve section. This broken screw extractor is suitable for enlarging or removing bone screws of various sizes, enabling rapid hole enlargement and screw removal with minimal bone damage and secondary injury. However, some problems still exist in practical use:

[0005] The aforementioned broken nail extractor uses a drill sleeve to drill and clamp the nail. However, the drill sleeve consists of three parts that do not contact each other. Direct drilling can easily cause the bone to get stuck in the gaps between the three parts of the drill sleeve, affecting operational efficiency. In addition, the inside of the drill sleeve is smooth, making it easy for the broken nail to slip during extraction, which can cause secondary injury to the patient.

[0006] Therefore, a simple broken nail remover is proposed to address the above problems. Utility Model Content

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Specific implementation examples are given below.

[0029] Please see Figures 1-4This utility model provides a technical solution: a simple broken nail remover, including a handle 1, a number of equally distributed anti-slip protrusions 11 are fixedly connected to the outer surface of the handle 1, and a fixing rod 2 is fixedly connected to the lower middle part of the outer surface of the handle 1. A clamping section 3 is fixedly connected to the lower part of the fixing rod 2. A tightening cap 4 is threadedly connected to the upper part of the outer surface of the clamping section 3, and a drill bit 5 is threadedly connected to the lower part of the inner surface of the clamping section 3.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, the drill bit 5 includes a metal ring 51, the lower part of which is integrally formed with a number of equally spaced circular arrays of serrations 52, and the upper middle part of the metal ring 51 is integrally formed with a connecting rod 53.

[0031] The above solution involves setting up a separate drill head 5. When removing broken nails, the drill head 5 can be connected to the clamping section 3. Then, the drill head 5 is placed against the bone surface at the nail removal location, and the device can be rotated to perform the drilling operation. The drill head 5 in this device is a closed ring structure with no gaps between it and the bone. During the drilling operation, the chance of jamming with the bone can be reduced, which can improve the efficiency of the nail removal operation.

[0032] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the clamping section 3 includes a hollow cone head 31. A connecting thread 32 is fixedly connected to the upper part of the outer surface of the hollow cone head 31, and the connecting thread 32 is threadedly connected to the tightening cap 4. A hollow tube 33 is fixedly connected to the lower part of the hollow cone head 31, and the hollow tube 33 communicates with the interior of the hollow cone head 31. A first connecting groove 34 is fixedly connected to the lower part of the inner surface of the hollow tube 33, and the first connecting groove 34 is threadedly connected to the connecting rod 53. Three equally spaced annularly distributed deformation grooves 35 are opened on the outer surface of the hollow tube 33 and the lower part of the outer surface of the hollow cone head 31. The tightening cap 4 includes a cap body 41. A second connecting groove 42 is opened on the inner surface of the cap body 41, and the second connecting groove 42 is threadedly connected to the connecting thread 32. Several equally spaced annularly distributed anti-slip strips 43 are fixedly connected to the outer surface of the cap body 41, and the cap body 41 is located between the handle 1 and the clamping section 3.

[0033] The above solution involves providing a first connecting groove 34 on the lower side of the hollow tube 33 in the clamping section 3. The first connecting groove 34 is in the form of a reverse thread, which can fit with the surface of the broken nail. When the hollow tube 33 is tightened by the tightening cap 4 to clamp the broken nail, the first connecting groove 34 can limit and fix the broken nail. The broken nail can be unscrewed by directly rotating the device. During operation, the broken nail can also be prevented from slipping off the clamping section 3, which not only improves the operation efficiency but also avoids secondary injury to the patient caused by the device slipping off the broken nail during the operation.

[0034] Working principle: First, connect the drill bit 5 to the clamping section 3. After the wound is exposed, place the drill bit 5 against the bone surface and rotate the device to drill into the bone surface. After the drilling is completed, remove the drill bit 5. Then, connect the lower part of the hollow tube 33 in the clamping section 3 to the broken nail. Then, rotate the tightening cap 4 so that the three parts divided in the hollow tube 33 clamp and fix the broken nail. At the same time, a first connecting groove 34 is opened on the lower side inside the hollow tube 33. The first connecting groove 34 has a reverse spiral structure, which can limit and fix the broken nail. After the device has fixed the broken nail, rotate the device to loosen and unscrew the broken nail.
