Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a punching aiming device for foot and ankle fracture surgery. Background Technology

[0002] The foot and ankle, or ankle joint, is one of the most critical and easily injured parts of the human body. Foot and ankle fractures are conditions caused by trauma to the ankle joint, which can lead to misalignment or breakage of the internal bone structures. During ankle fracture repair surgery, the misaligned or broken bones must first be repositioned. Then, orthopedic pins are used to create perforations in the bones on both sides of the fracture site after repositioning. Finally, the misaligned or broken bones can be fixed either directly with orthopedic pins or with hollow screws.

[0003] Before drilling into the bone at the fracture site, a drill is needed to drill into the fractured bone. A sight is also needed during the drilling process to prevent the medical staff from deviating from the target bone during the drilling process, which could cause secondary injury to the patient.

[0004] The existing punch aiming device has a relatively complex structure, making it inconvenient for medical personnel to use. Summary of the Invention

[0020] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0021] Please see Figure 1-3 This utility model provides a punching aiming device for foot and ankle fracture surgery, comprising: a strap 1, a fixing base 2, a telescopic assembly 3, a first fixing assembly 4, a second fixing assembly 5, a reflector assembly 6, and an infrared generator 7; the strap 1 is disposed on the fixing base 2 for fixing the fixing base 2 to the human leg; the telescopic assembly 3 includes a first telescopic member 31 and a second telescopic member 32, the first telescopic member 31 and the second telescopic member 32 respectively including an arc-shaped segment and a fixed segment; the fixed segment of the first telescopic member 31 is rotatably connected to the fixing base 2, the first fixing assembly 4 is disposed at the connection between the fixed segment of the first telescopic member 31 and the fixing base 2 for fixing the first telescopic member 31 to the fixing base 2; the arc-shaped segment of the second telescopic member 32 is slidably connected to the arc-shaped segment of the first telescopic member 31, the second fixing assembly 5 is disposed on the arc-shaped segment of the second telescopic member 32 for fixing the second telescopic member 32 to the first telescopic member 31; the reflector assembly 6 is rotatably disposed on the fixed end of the second telescopic member 32, and the infrared generator 7 is disposed on the fixed end of the second telescopic member 32.

[0022] In this embodiment, by setting a rotatable connection between the fixed base 2 and the fixed section of the first telescopic member 31, the first telescopic member 31 can rotate relative to the fixed base 2 during use, and can be fixed by the first fixing component 4 after rotation. By setting a sliding connection between the arc-shaped section of the second telescopic member 32 and the arc-shaped section of the first telescopic member, the length of the telescopic component 3 can be adjusted during use, and can be fixed by the second fixing component 5 after adjustment. Furthermore, the reflector component 6 is rotatably mounted on the fixed end of the second telescopic member 32, so that the reflector component 6 can reflect the infrared light from the infrared generator 7 onto the bone at the fracture site. Through the above adjustments, interference between the telescopic component 3, the reflector component 6, and the punch can be avoided, facilitating use by medical personnel. The infrared generator 7 can be an infrared generator, such as a laser pointer, used to emit infrared light.

[0023] The first fixing section includes a cylindrical segment 311 and a spherical segment 312. One end of the cylindrical segment 311 is connected to the arc-shaped segment of the first telescopic member 31, and the other end is connected to the spherical segment 312. The first fixing assembly 4 includes a fixing post 41 and a nut 42. One end of the fixing post 41 is connected to the fixing seat 2, and the other end is provided with a first mounting cavity 411 for accommodating the cylindrical segment 311 and a second mounting cavity 412 for accommodating the spherical segment 312. The fixing post 41 is also provided with a rectangular groove 413 that divides the first mounting cavity 411 and the second mounting cavity 412 of the fixing post 41 into two parts along the extension direction of the fixing post 41. The nut 42 is threadedly connected to the outer surface of the fixing post 41.

[0024] The diameter of the cylindrical segment 311 is smaller than the diameter of the spherical segment 312. Specifically, the cylindrical segment 311 and the first mounting cavity 411 can be clearance-fitted, while the spherical segment 312 and the second mounting cavity 412 can be interference-fitted. During installation, the spherical segment 312 can pass through the first mounting cavity 411 and then be assembled into the second mounting cavity 412. Because the second mounting cavity 412 and the spherical segment 312 are interference-fitted, when the nut 42 is screwed to the outside of the corresponding second mounting cavity 412, the nut 42 causes the fixing post 41 to elastically deform at the position corresponding to the second mounting cavity 412, so that the second mounting cavity 412 and the spherical segment 312 are tightly abutted, thereby securely fixing the spherical segment 312 in the second mounting cavity 412 and preventing the spherical segment 312 from rotating.

[0025] The strap 1 may include a first sub-strap 11 and a second sub-strap 12. One end of the first sub-strap 11 is connected to the fixing base 2, and the other end is provided with a first fixing member 111. One end of the second sub-strap 12 is connected to the fixing base 2, and the other end is provided with a second fixing member 121 for connecting with the first fixing member 111. The strap 1 may be made of an elastic material, such as nylon, so that the strap 1 can fit snugly to the person's leg. To facilitate fixing the first sub-strap 11 and the second sub-strap 12 to the person's leg, the first fixing member 111 is a Velcro velvet surface, and the second fixing member 121 is a Velcro adhesive surface.

[0026] The second telescopic member 32 has an accommodating cavity within its arc-shaped segment for accommodating the arc-shaped segment of the first telescopic member 31. The second fixing assembly 5 includes a first threaded through hole on the arc-shaped segment of the second telescopic member 32 and a first screw 51 threadedly connected to the threaded through hole. One end of the first screw 51 passes through the first threaded through hole and abuts against the side of the arc-shaped segment of the first telescopic member 31 to fix the second telescopic member 32 onto the first telescopic member 31. Specifically, the first threaded through hole is located on the side of the arc-shaped segment of the second telescopic member 32 near the fixing end of the first telescopic member 31. After the first screw 51 passes through the first threaded through hole and abuts against the side of the arc-shaped segment of the first telescopic member 31, the first screw 51 forms a surface contact with the side of the first telescopic member 31. Then, the other side of the first telescopic member 31 opposite to the side of the first screw 51 abuts against the side of the accommodating cavity, thereby fixing the second telescopic member 32 and the first telescopic member 31 to prevent relative displacement of the first telescopic member 31 and the second telescopic member 32 during use.

[0027] The reflector assembly 6 includes a reflector 61 and an L-shaped mounting plate 62. The reflector 61 is rotatably mounted at the end of the long side of the L-shaped mounting plate 62, and the short side of the L-shaped mounting plate 62 is rotatably connected to the arc-shaped segment of the second telescopic member 32. Specifically, the rotatable connection between the short side of the L-shaped mounting plate 62 and the arc-shaped segment of the second telescopic member 32 is located at the top of the end of the arc-shaped segment of the second telescopic member 32 away from the fixed segment of the first telescopic member 31, and the infrared generator 7 is located at the bottom of the end of the arc-shaped segment of the second telescopic member 32 away from the fixed segment of the first telescopic member 31.

[0028] By rotatably connecting the reflector 61 to the long side of the L-shaped mounting plate 62 and rotatably connecting the short side of the L-shaped mounting plate 62 to the arc-shaped segment of the second telescopic member 32, the reflector 61 can rotate to a greater angle so as to reflect the infrared light of the infrared generator 7 onto the bone of the fractured part, and avoid interference between the reflector assembly 6 and the punch.

[0029] The reflector assembly 6 may further include a second screw 63, which is fixedly mounted on the end of the arc-shaped segment of the second telescopic member 32 away from the fixed segment. A second threaded through hole is provided on the short side of the L-shaped mounting plate 62, and the L-shaped mounting plate 62 is rotatably connected to the second screw 63 through the second threaded through hole. Specifically, the second threaded through hole of the L-shaped mounting plate 62 is connected to the threaded segment of the second screw 63, thereby achieving a rotatable connection. The reflector assembly 6 also includes a rotating shaft. A rotating shaft hole is provided at the end of the long side of the L-shaped mounting plate 62. The rotating shaft is mounted on the reflector 61, and the rotating shaft and the rotating shaft hole are interference-fitted. The rotating shaft can be fixedly connected to the reflector 61, and then interference-fitted with the rotating shaft hole, so that after the reflector 61 rotates a certain angle, it can be fixed in its rotated position by the interference fit between the rotating shaft and the rotating shaft hole. It can be understood that the interference fit referred to in this article refers to a fit state in which the two parts, after being assembled together, can still rotate relative to each other under a certain external force.

[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
