Description

Technical Field

[0001] The utility model relates to the technical field of bone trauma measurement, in particular to a measuring ruler for bone trauma. Background Art

[0002] Bone trauma refers to damage to bones caused by external forces. When bones are hit, squeezed, etc. by external forces, fractures, dislocations or other types of injuries may occur. These injuries may affect the integrity of the bone structure and thus its function. X-ray examination is one of the important means of diagnosing bone trauma, which can show fracture lines, displacement, and whether there are complications. After the doctor gets the patient's X-ray, in addition to judging the patient's injuries, he can also measure the trauma site with a measuring ruler to specify the specific situation of the trauma, such as the specific location, depth, length and other parameters of the trauma, thereby providing intuitive and accurate treatment parameters for the later treatment of the trauma site.

[0003] After searching, the Chinese patent with publication number CN 212963107 U in the prior art discloses an orthopedic trauma measuring ruler, including a main body, a laser pen and a moving block, one side of the main body is fixedly connected to a mounting block, the interior of the mounting block is provided with a mounting groove, one side of the interior of the mounting groove is fixedly connected to a clamping plate, and the interior of the clamping plate is clamped with a spring. The utility model drives one of the laser pens to move to the measuring point through the moving block, and then indicates the reading through the cooperation of the pointer at the upper end of the moving block and the ruler. Although the application can measure the length of the trauma through the cooperation of the moving laser pen, the pointer and the ruler, it can only measure the length in a single direction each time, and it is difficult to accurately depict the specific position and length, width, depth and other parameters of the trauma, and the moving block will also cause certain obstacles to the observation field of the laser pen positioning point, affecting the positioning accuracy.

[0004] Furthermore, the Chinese patent with publication number CN207936878U discloses an orthopedic trauma measuring ruler, including a measuring ruler body, the measuring ruler body including a measuring ruler body, a protective shell 1 and a protective shell 2, a transparent baffle is arranged on the top of the measuring ruler body, a red scale line is arranged on the transparent baffle, a laser light disk switch is arranged on one side of the transparent baffle, and a laser light disk and a battery are arranged in the measuring ruler body. Although the application can avoid affecting the doctor's observation field by placing the X-ray film directly on the top of the laser disk and positioning it through multiple red scale lines, the laser light disk directly irradiates upward and directly enters the doctor's observation field, which will not only damage the doctor's eyes, but also the multiple red scale lines, the human body projection line on the X-ray film, and the light emitted by the laser disk will inevitably make the doctor dizzy, making it difficult for him to accurately read the accurate value.

[0005] To this end, the present application provides a measuring ruler for bone trauma to solve the above-mentioned problems. Utility Model Content

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0032] Example 1: See Figure 1-Figure 3 As shown, this embodiment provides a measuring ruler for bone trauma, and its structural design includes a bracket 1, a placement plate 2, a positioning component 3 and a measuring component 4. The bracket 1 includes four pillars 11, and suction cups 12 are provided at the bottom of the four pillars 11.

[0033] The storage board 2 is composed of a U-shaped frame 21 and a transparent plate 22. The four corners of the frame 21 are fixedly connected to the four pillars 11, and the transparent plate 22 is embedded in the frame 21. Two opposite side walls of the frame 21 are symmetrically provided with two slide grooves 211, and at least one pressure rod 5 is movably connected between the two slide grooves 211; both ends of the pressure rod 5 are rotatably connected to the limit blocks 51, and the two limit blocks 51 are slidably embedded in the slide grooves 211. A torsion spring 52 is connected between the pressure rod 5 and the limit blocks 51. The pressure rod 5 is adjustably pressed against the top surface of the storage board 2 through the limit blocks 51 and the torsion spring 52. The middle section of the pressure rod 5 has an operating section 53, and the operating section 53 is in an upward state when the pressure rod 5 is pressed flat on the top surface of the storage board 2. The four corners of the storage board 2 are fixedly connected to the four pillars 11.

[0034] The positioning assembly 3 and the measuring assembly 4 are movably connected to the bracket 1, and the measuring assembly 4 includes two measuring units 41, and the measuring directions of the two measuring units 41 are perpendicular to each other. The positioning assembly 3 includes a first slide rail 31, and the first slide rail 31 is slidably sleeved with a first guide rail 32 at both ends, and the first guide rail 32 is fixedly connected to the bracket 1 at both ends. The first slide rail 31 is movably sleeved with a slider 33, and the side of the slider 33 is fixedly connected with at least one support rod 34, and the support rod 34 is fixedly connected with an elastic snap ring 35 with an opening, and the elastic snap ring 35 is detachably connected with a laser pen 36, and the distance between the laser pen 36 and the first slide rail 31 is greater than zero.

[0035] The measuring unit 41 includes a rangefinder 411 and a reflector 412. A case 413 is provided on the top of the slider 33. The rangefinders 411 of the two measuring units 41 are respectively embedded in adjacent side walls of the case 413. The reflectors 412 of the two measuring units 41 are fixedly connected to the bracket 1, and the two reflectors 412 are respectively arranged opposite to the transmitting ends of the rangefinders 411. A display screen 414 is provided on the top of the case 413, and the display screen 414 is electrically connected to the two rangefinders 411.

[0036] The working principle of this embodiment is summarized as follows:

[0037] Before use, the doctor firmly fixes the entire measuring ruler on the desktop through the suction cup 12 at the bottom of the support 11, fixes the laser pen 36 on the elastic clamp 35, and then lifts the pressure rod 5 with one hand through the operating section 53 of the pressure rod 5, places the X-ray film on the placement plate 2, so that the position of the bone injury to be measured is located on the top plate of the transparent plate 22, and then puts down the pressure rod 5. The pressure rod 5 will firmly fix the X-ray film under the action of the torsion spring 52.

[0038] Then, the laser pen 36 can be moved to any position within the range of bone trauma on the X-ray film by moving the slider 33 along the first slide rail 31 and the first slide rail 31 along the first guide rail 32. The two rangefinders 411 can measure a data respectively and display it on the display screen 414. After recording, the length, width and other data of the bone trauma can be obtained by calculating the difference between the readings of the rangefinder 411 at different points, thereby guiding the doctor to clarify the range of the trauma for targeted treatment.

[0039] Furthermore, the doctor can first move the laser pen 36 to a relatively prominent position of the human body shown on the X-ray film as a reference point, and then move the laser pen 36 to measure data within the range of bone trauma. By calculating the data difference between the reference point and the point within the range of bone trauma, the doctor can be guided to accurately find the bed position on the human body to perform treatment operations.

[0040] In summary, in this embodiment, the laser pen 36 can be positioned at any position of the X-ray film through the movement of the slider 33 and the first slide rail 31. Not only can the range of bone trauma be quickly determined by calculating the difference in the rangefinder 411 data between different points, but also the doctor can be guided to accurately determine the specific position of the trauma in the human body by setting reference points, thereby achieving precise treatment. The detection using the rangefinder 411 has a small error and higher accuracy. Moreover, the rangefinder 411 is independently mounted outside the first slide rail 31 through the support rod 34, which is convenient for the doctor to accurately observe the positioning position without obstruction of the field of vision.

[0041] Example 2: See Figure 4 As shown, the present embodiment provides a measuring ruler for bone trauma, which is different from the embodiment 1 in that:

[0042] One of the measuring units 41 includes a first slide rail 31, and a scale 415 is provided on the top surface of the first slide rail 31; the other measuring unit 41 includes a second slide rail 416 perpendicular to the first slide rail 31, the second slide rail 416 is slidably connected to the slider 33, and a scale 415 is also provided on the top surface of the second slide rail 416; the two ends of the second slide rail 416 are slidably sleeved with a second guide rail 417, and the two ends of the second guide rail 417 are fixedly connected to the bracket 1.

[0043] The working principle of this embodiment is summarized as follows:

[0044] The installation and fixing method of the entire measuring ruler and the installation of the laser pen 36 are the same as those in Example 1, and will not be described in detail in this embodiment. What is different from Example 1 is that the measuring unit 41 of this embodiment does not use the rangefinder 411 to directly read the data, but instead sets a scale 415 on the cross-intersecting first slide rail 31 and the second slide rail 416 for reading the data. Compared with Example 1, the use of electrical equipment is reduced, and it is more energy-saving, environmentally friendly, economical and practical.
