Description

Technical Field

[0001] The utility model relates to the technical field of wrist joint fixation frames, in particular to a disposable nail track protection device. Background Art

[0002] A wrist fixation frame is a medical device that is mainly used to fix and protect the wrist joint, and to provide support and rehabilitation assistance in cases of wrist fracture, sprain, strain, tenosynovitis, carpal tunnel syndrome, etc.

[0003] The wrist fixator, through its structural design, can fit closely to the wrist joint, provide stable fixation and support, and prevent further damage or displacement of the joint. After a wrist fracture, the wrist fixator can also be used to fix the fracture site, prevent fracture displacement, and promote fracture healing. The existing wrist fixator has a fixed position of the nail channels due to the inability to adjust the spacing between the nail channels, which makes it impossible to flexibly adjust the position according to the patient's specific situation, such as wrist size, injury type, treatment needs, etc. This will cause the fixator to be unable to fit closely to the patient's wrist joint in some cases, thereby affecting the stability and effect of the fixation.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] See also Figure 1-5The utility model provides a technical solution: a disposable nail protection device, including a support plate 1, a spacing adjustment component 2 is provided on the surface of the support plate 1, the spacing adjustment component 2 includes a fixing frame 201, the fixing frame 201 is fixedly connected to one side surface of the support plate 1, the other side surface of the support plate 1 is provided with a screw groove 202, a one-way screw 203 is inserted into the screw groove 202, one end of the one-way screw 203 is connected to a handle 204, the other end of the one-way screw 203 is connected to a first bearing 205, and the surface of the one-way screw 203 is connected to a moving block 206, a threaded hole 207 is provided inside the moving block 206, and a moving frame 208 is connected to the top of the moving block 206. A sliding rod 209 is connected to the side of the moving frame 208 close to the fixed frame 201, and a sliding sleeve 210 is connected to the side of the fixed frame 201 close to the moving frame 208. A groove 211 is provided on the surface of the sliding sleeve 210, and a sleeve 212 is connected to the surface of the groove 211. A second bearing 213 is connected to the surface of the sleeve 212. A connecting block 214 is connected to the surface of the second bearing 213, and a fixing pin 215 is inserted into the interior of the connecting block 214.

[0024] like Figure 3-4 As shown, a fixed connection is formed between the one-way screw 203 and the handle 204, and a rotational connection is formed between the one-way screw 203 and the first bearing 205. When the handle 204 is rotated, the one-way screw 203 can also be driven to rotate, thereby adjusting the nail channel spacing. The first bearing 205 can improve the stability of the one-way screw 203 during rotation.

[0025] like Figure 1 - Figure 4 As shown, the size of the fixed frame 201 is the same as that of the movable frame 208, and the movable block 206 is threadedly connected with the one-way screw 203 through the threaded hole 207. When the one-way screw 203 rotates, it will threadably rotate with the one-way screw 203 through the threaded hole 207, thereby driving the movable frame 208 to move.

[0026] like Figure 2 and Figure 4 As shown, the outer surface of the slide rod 209 fits with the inner wall of the slide sleeve 210, the slide sleeve 210 and the slide rod 209 form a sliding connection, and the connecting block 214 and the fixing pin 215 form a threaded connection. When the movable frame 208 moves, it will also push the slide rod 209 to slide in the slide sleeve 210, thereby improving the stability during movement, and the fixing pin 215 can be moved downward by rotating the thread to fix the patient's wrist.

[0027] like Figure 6As shown, the four corners of the bottom of the support plate 1 are connected to support adjustment components 3, which include support columns 301. The support adjustment components 3 can adjust the height of the support plate 1, so that the support plate 1 can be adjusted according to the needs of the patient, thereby improving the patient's comfort.

[0028] like Figure 6 As shown, a threaded groove 302 is provided inside the support column 301, a threaded rod 303 is provided inside the threaded groove 302, and a support foot 304 is connected to the bottom of the threaded rod 303. The height of the support foot 304 can be adjusted by rotating the thread between the threaded rods 303 and the threaded rods 303.

[0029] The method of use and working principle of this device are as follows: when fixing the wrists of different patients and adjusting the spacing of the nail channels of the mobile frame 208, the handle 204 can be rotated in the forward direction to drive the one-way screw 203 to rotate, so that the one-way screw 203 can be threadedly rotated with the moving block 206 through the threaded hole 207, and the moving frame 208 can be moved toward the fixed frame 201 through the threaded rotation. While moving, the sliding rod 209 will also slide in the sliding sleeve 210, thereby adjusting the distance between the mobile frame 208 and the fixed frame 201. Similarly, when the handle 204 is rotated in the reverse direction, the mobile frame 208 will also be driven to move outward. Then, the patient's arm is passed through the fixed frame 201 and the mobile frame 208, and then the sleeve 212 is used to By rotating the longitudinal angle of the fixing pin 215, the lateral angle of the fixing pin 215 can be adjusted through the second bearing 213. When the output end angle of the fixing pin 215 matches the position to be fixed of the patient's hand, the fixing pin 215 can be rotated, and the output end of the fixing pin 215 is driven to contact the patient's wrist through threaded rotation. In this way, the protection of the nail channel can be achieved through the sliding sleeve 210, which improves the overall practicality. At the same time, it also avoids the problem that the existing nail channel cannot adjust the spacing according to actual conditions. By rotating the supporting foot 304, the supporting foot 304 can drive the threaded rod 303 and the threaded groove 302 to rotate, thereby adjusting the height of the supporting foot 304, ensuring that the support plate 1 can be adjusted according to the needs of the patient, thereby improving the comfort of the patient when using it.
