[0002] Currently, many surgeries or recovery procedures require measurement of the incision angle or the recovery angle to ensure that the angle can be measured with minimal wound after the incision.

[0003] For example, the episiotomy doctor can better understand the structure and position of the perineal tissue, as well as the optimal angle and depth of the incision. This can not only reduce damage to surrounding tissues, but also minimize the risk of complications such as bleeding and infection. The current method for episiotomy is to rely directly on the doctor's experience for rough comparison. The measurement accuracy is very low and may cause damage. Secondly, during recovery after knee replacement surgery, the patient's knee joint needs to be gradually raised. At this time, the angle between the bed surface and the knee joint needs to be measured, and then gradually increased to promote the patient's recovery. For the above two methods, there is currently no accurate measurement device. Therefore, a multifunctional angle measurer is needed. Summary of the Invention

[0033] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0034] Example 1

[0035] See also Figure 1 - Figure 11 A multifunctional angle measuring device includes a fixing base 1, a measuring ring, an elevated measuring plate 4, and a bevel measuring plate 15. The back of the fixing base 1 is provided with a groove for docking with the bed frame. A connecting plate 2 is fixedly installed at the fixed front end by screws. The front side of the connecting plate 2 is rotatably connected to the elevated measuring plate 4 through a mounting rod 3 in conjunction with a bearing. A pointer boss 5 is fixedly installed at the front side of one end of the elevated measuring plate 4. A digital scale ring 6 is sleeved on the outside of the pointer boss 5. A strip scale ring 7 is installed on the outside of the digital scale ring 6 through a bearing. The strip scale ring 7 is fixed to the front surface of the connecting plate 2 through an L-shaped support rod 8 in conjunction with screws:

[0036] The other end of the lifting measuring plate 4 is sleeved with a stretchable extension plate 9, and the back of the end of the extension plate 9 is hinged with a fitting ruler 10. The middle of the fitting ruler 10 is provided with a mounting hole for embedding a horizontal detection ruler 11. The upper surface of the end of the extension plate 9 is integrally formed with two clips 13 for clamping a T-shaped clip 12. The upper end of the T-shaped clip 12 is fixedly mounted with a sleeve block 14. The interior of the sleeve block 14 is hinged with a bevel measuring plate 15 for measuring the bevel angle of the parturient. The other end surface of the bevel measuring plate 15 is fixedly mounted with an angle arc plate 16, which is connected to the give way groove opened in the middle of the sleeve block 14.

[0037] One end of the sleeve block 14 is fixedly installed with a positioning block 17, and a cavity for the installation of a spring pin 18 is opened inside the wall of the other end of the sleeve block 14. Considering that angle measurement is required in episiotomy surgery and knee replacement lifting care, the present invention uses the lifting measuring plate 4, pointer boss 5, digital scale ring 6, fitting ruler 10 and bar scale ring 7 to measure the lifting angle during knee replacement lifting care, and the bevel measuring plate 15 and angle arc plate 16 in the sleeve block 14 clamped at the upper end of the lifting measuring plate 4 of the present invention play a measuring role for postpartum women who need bevel cutting, so that the present invention has the characteristics of multi-functional use. When measuring the angle of the patient's calf lifting after knee replacement surgery, the fixing seat 1 is connected to the patient's bed frame, and the interference bolt 29 is tightened to make the pressure plate 30 contact with the bed frame to complete the fixation, and then the U-shaped fixing block used to fix the lifting measuring plate 4 is removed, and then the lifting When the height difference is large, the length of the measuring plate 4 can be increased by stretching the extension plate 9. After the adjustment, the fitting ruler 10 is ensured to be level with the patient's calf. At this time, the pointer boss 5 of the measuring plate 4 is observed to point to the position of the digital scale ring 6 and the bar scale ring 7, so as to know the lifting angle. When measuring the bevel angle of the parturient, the measuring plate 4 is first rotated to be perpendicular to the connecting plate 2, and then the T-shaped card block 12 is used to engage the card strip 13 to complete the installation. Then the bevel measuring plate 15 inside the sleeve block 14 is rotated open. When it is rotated to 45 degrees or 60 degrees, the spring pin 18 is released. The spring pin 18 is pressed into the countersunk hole 24 to complete the fixation. Then the medical staff can use surgical instruments to perform bevel cutting. The depth of the bevel cutting can be measured according to the scale of the bevel measuring plate 15.

[0038] Please refer to Figure 3 、 Figure 4 and Figure 6 As shown, a battery holder 19 and a miniature cross positioning light 20 are installed inside the alignment block 17 respectively. A button battery is provided inside the battery holder 19, and the button battery is connected to the miniature cross positioning light 20 circuit. By setting the miniature cross positioning light 20, an auxiliary positioning effect is played in the bevel position measurement process. The cross-shaped light beam emitted by the miniature cross positioning light 20 can be used to know whether the position of the bevel measurement board 15 is perpendicular to the ground at this time. When the cross light beam is found to be tilted, it means that the bevel measurement board 15 is tilted during use and is not in a vertical state.

[0039] Please pay special attention to the figure. A cavity is provided inside the end of the extension plate 9 for the two positioning pressure blocks 21 to be movably connected. A return spring 22 is abutted between the two positioning pressure blocks 21, and the upper ends of the two positioning pressure blocks 21 are respectively located in the adjustment holes 23. The adjustment holes 23 are opened at intervals on the upper and lower sides of the extension plate 9. The positioning pressure blocks 21 are provided to fix the position of the stretched extension plate 9.

[0040] Please refer to Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 、 Figure 11 As shown, one end of the bevel measuring plate 15, the 45-degree scale position of the angle arc plate 16, and the 60-degree position of the angle arc plate 16 are all provided with countersunk holes 24 for the pin head of the spring pin 18 to abut against. The presence of the countersunk holes 24 helps the user to quickly fix the beveled 45-degree scale and 60-degree scale positions, adapting to the situation where the incision angle should be increased to 60 degrees when the perineum is highly bulging.

[0041] Please refer to Figure 1 and Figure 2 As shown, two fixing grooves 25 for the same U-shaped fixing block to be inserted are symmetrically opened on the other side of the front end of the connecting plate 2, and the first magnetic block 26 for magnetically adsorbing the U-shaped fixing block is fixed inside the two fixing grooves 25. A collar 27 is integrally formed on the front end surface of the U-shaped fixing block, and the collar 14 is fixed to the limit block 28 at the bottom of the fixing seat 1 by a connecting rope. By setting the U-shaped fixing block to lift the measuring plate 4 when it is not in use, it plays a restraining role to prevent it from rotating arbitrarily.

[0042] Please refer to Figure 1 、 Figure 2 and Figure 5 As shown, both sides of the upper end of the fixing seat 1 are threadedly connected with a contact bolt 29, and the bottoms of the two contact bolts 29 are located in the middle of the groove on the back of the fixing seat 1 and are fixed to the pressure plate 30 through bearings. The bottoms of the two pressure plates 30 are bonded with rubber anti-slip pads 31. By setting the contact bolts 29 and cooperating with the pressure plates 30, the fixing seat 1 is fixed to the bed frame. When measuring by bevel cutting, it is not necessary to fix it, and the fixing seat 1 can be directly placed horizontally on the delivery bed for the mother.

[0043] Please refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8As shown, the front end surface of the bar scale ring 7 is provided with a recessed groove that is adapted to the front end contour of the digital scale ring 6, and the opposite surfaces of the recessed groove and the digital scale ring 6 are provided with an engaging hole for the second magnetic block 32 to be embedded. By setting a rotatable structure for the digital scale ring 6, it is convenient for the user to customize the measurement position of the digital scale ring 6 corresponding to the bar scale ring 7, that is, the zero degree position of the digital scale ring 6 can be rotated and adjusted according to the needs of the user, which is convenient for reading.

[0044] Example 2

[0045] See also Figure 1 - Figure 12 A multifunctional angle measuring device further includes a first substitute ruler 33. One side of the T-shaped block 12 can also be fixed with the first substitute ruler 33 for replacing the angle arc plate. Considering that the angle of the perineum of a conventional parturient is 45 degrees, in order to improve the efficiency of beveling, in normal circumstances, the substitute ruler will be directly used for medical staff to perform a standard 45-degree beveling.

[0046] See also Figure 1 - Figure 13 A multifunctional angle measuring device also includes a second alternative ruler 34. One side of the T-shaped block 12 can also be fixed with a second alternative ruler 34 for replacing the angle arc plate. The second alternative ruler 34 is used to assist in 60-degree bevel cutting of the perineum.
