[0052] The following describes in detail the arc measuring device for the connecting rod 40 during spinal surgery according to an embodiment of the present invention with reference to the accompanying drawings.

[0053] Reference Figures 1 to 5 As shown, the arc measuring device of the connecting rod 40 provided during spinal surgery according to an embodiment of the present invention includes an upper fixing assembly 10, a lower fixing assembly 20 and an angle measuring member 30;

[0054] The upper fixing assembly 10 includes an upper fixing member 11 and an upper connecting member 12 ; the upper fixing member 11 is used to fix the upper end of the connecting rod 40 ; the upper end of the upper connecting member 12 is connected to the upper fixing member 11 .

[0055] The lower fixing assembly 20 includes a lower fixing member 21 and a lower connecting member 22 ; the lower fixing member 21 is used to fix the lower end of the connecting rod 40 ; the lower end of the lower connecting member 22 is connected to the lower fixing member 21 .

[0056] Specifically, the upper fixing assembly 10 and the lower fixing assembly 20 are split, wherein the upper fixing assembly 10 includes an upper fixing member 11 and an upper connecting member 12, the upper connecting member 12 and the upper fixing member 11 are vertically connected, and the upper fixing member 11 can connect the upper end of the bent connecting rod 40, and when the upper fixing member 11 is connected to the connecting rod 40, the tangent of the connection position of the upper end of the connecting rod 40 can be perpendicular to each other; similarly, the lower fixing assembly 20 includes a lower fixing member 21 and a lower connecting member 22, and the lower connecting member 2 2 is vertically connected to the lower fixing member 21. The lower fixing member 21 can connect the lower end of the bent connecting rod 40, and when the lower fixing member 21 is connected to the connecting rod 40, the tangent of the connection position of the lower end of the connecting rod 40 can be perpendicular to each other; in this way, the upper connecting member 12 vertically connected to the upper fixing member 11 can form an angle with the lower connecting member 22 vertically connected to the lower fixing member 21, and the angle is equal to the bending angle of the connecting rod 40. Therefore, by measuring the angle, the bending angle of the connecting rod 40 can be known.

[0057] The angle measuring member 30 is disposed on the lower connecting member 22 and is used to measure the angle formed by the upper connecting member 12 and the lower connecting member 22 when the upper fixing member 11 and the lower fixing member 21 fix the connecting rod 40 .

[0058] The angle measuring part 30 can be a protractor (scale not shown), which is set on the lower connecting part 22. Then, it can be used to measure the angle between the upper connecting part 12 and the lower connecting part 22. From this, the bending angle of the connecting rod 40 can be obtained, which makes it convenient for medical personnel to judge whether the angle of the connecting rod 40 is appropriate.

[0059] It is worth noting that when the connecting rod 40 is in a straight rod state, if the upper fixing member 11 and the lower fixing member 21 are respectively connected to the two ends of the connecting rod 40, at this time, the upper fixing member 11 and the lower fixing member 21 are respectively perpendicular to the two ends of the connecting rod 40, while the upper connecting member 12 and the lower connecting member 22 are parallel to the connecting rod 40. If the connecting rod 40 is bent by controlling the upper fixing member 11 and the lower fixing member 21 at this time, the upper connecting member 12 and the lower connecting member 22 will rotate and stagger with each other and form an angle. Then, the bending angle of the connecting rod 40 is equal to the angle formed between the upper connecting member 12 and the lower connecting member 22. In other words, if the angle formed between the upper connecting member 12 and the lower connecting member 22 is measured, the bending angle of the connecting rod 40 can also be known. This is the origin of the bending angle of the connecting rod 40 in this application by measuring the angle between the upper connecting member 12 and the lower connecting member 22.

[0060] The arc measuring device for the connecting rod 40 during spinal surgery provided by the present invention has a simple structure and is easy to use. It can very conveniently measure the bending angle of the connecting rod 40, thereby helping doctors to determine whether the connecting rod 40 is suitable for use.

[0061] Advantageously, in one embodiment of the present invention, the upper fixing member 11 includes an upper rod body 111 and an upper screw rod 112. The left end of the upper rod body 111 is provided with an upper fixing hole 1111 for the upper end of the connecting rod 40 to pass through. The upper screw rod 112 is provided at the right end of the upper rod body 111 and is inserted into the upper fixing hole 1111 to fix the upper end of the connecting rod 40.

[0062] The lower fixing member 21 includes a lower rod body 211 and a lower screw rod 212. The left end of the lower rod body 211 is provided with a lower fixing hole 2111 for the lower end of the connecting rod 40 to pass through. The lower screw rod 212 is provided at the right end of the lower rod body 211 and passes through the lower fixing hole 2111 to fix the lower end of the connecting rod 40.

[0063] The upper fixing hole 1111 and the lower fixing hole 2111 can be circular holes or square holes. In this embodiment, the upper fixing hole 1111 and the lower fixing hole 2111 are square holes. When in use, the upper end of the connecting rod 40 is inserted into the upper fixing member 11, and the upper screw 112 is rotated. The upper end of the connecting rod 40 is clamped by the upper screw 112. At the same time, the lower end of the connecting rod 40 is inserted into the lower fixing member 21, and the lower screw 212 is rotated. The upper end of the connecting rod 40 is clamped by the lower screw 212 to fix the two ends of the connecting rod 40. After fixation, the angle between the upper connecting member 12 and the lower connecting member 22 can be measured using the angle measuring member 30. In addition, since the two ends of the connecting rod are locked by the upper screw 112 and the lower screw 212, when connecting rods of different sizes are inserted into the upper fixing hole 1111 and the lower fixing hole 2111, they can be locked by adjusting the depth of the upper screw 112 and the lower screw 212 inserted into the locking hole of the upper screw 112 and the lower screw 212, thereby making the present application applicable to connecting rods of different sizes.

[0064] It should be noted that the inner walls of the upper fixing hole 1111 and the lower fixing hole 2111 may have a certain curvature so as to better fit the upper and lower ends of the connecting plate.

[0065] Advantageously, in one embodiment of the present invention, the upper connecting member 12 is rotatably connected to the upper fixing member 11 and can be switched between a horizontal state and a vertical state; when the upper connecting member 12 is switched to the vertical state, the upper connecting member 12 can be locked and fixed by an upper locking member provided on the upper fixing member 11;

[0066] The lower connecting member 22 is rotatably connected to the lower fixing member 21 and can be switched between a horizontal state and a vertical state; when the lower connecting member 22 is switched to the vertical state, the lower connecting member 22 can be locked and fixed by a lower locking member provided on the lower fixing member 21.

[0067] In other words, the upper connecting member 12 and the lower connecting member 22 can both be rotated to a vertical position and a horizontal position. At this time, the positions of the upper connecting member 12 and the lower connecting member 22 can be switched according to the usage. When not in use, they can be switched to the horizontal position, thus reducing the space occupied by the two when stored. When needed, they can be switched to the vertical position and locked and fixed with the corresponding upper locking member and lower locking member. In this embodiment, the upper locking member and the lower locking member can be screws with handles, which have a good locking effect and are easy to operate, which is convenient for use.

[0068] Advantageously, in one embodiment of the present invention, the upper connecting member 12 is a rod-shaped structure, the lower connecting member 22 is a U-shaped structure, and the upper connecting member 12 is suitable for being inserted into the lower connecting member 22 .

[0069] In this way, when the upper connecting member 12 and the lower connecting member 22 are switched to the vertical state, after the connecting rod 40 is fixed by the upper fixing member 11 and the lower fixing member 21, the upper connecting member 12 can be inserted into the lower connecting member 22 and intersect with the lower connecting member 22 to form an angle. In this way, the distance between the upper connecting member 12 and the angle measuring member 30 is closer, which is conducive to the angle measuring member 30 to measure the value of the angle, thereby calculating the curvature of the connecting rod 40, avoiding the reading error caused by the upper connecting member 12 being too far away from the angle measuring member 30.

[0070] Advantageously, another embodiment of the present invention further includes an angle fixing assembly 50 for fixing the upper connecting member 12 and the lower connecting member 22 when the upper connecting member 12 and the lower connecting member 22 rotate relative to each other to form an angle.

[0071] In this way, after the upper connecting member 12 and the lower connecting member 22 rotate relative to each other to form an angle, the two are locked using the angle fixing component 50. Then, the angle between the two can be locked and will not change, making it convenient to read the value of the angle. This is also conducive to measurement using the angle measuring member 30.

[0072] Advantageously, in some embodiments of the present invention, the angle fixing assembly 50 includes a sleeve rod 51 and a fixing member 52;

[0073] The right end of the sleeve rod 51 is slidably sleeved on the upper connecting member 12;

[0074] The fixing member 52 is disposed at one end of the lower connecting member 22 and can lock and fix the left end of the sleeve rod 51 when the left end of the sleeve rod 51 is inserted into the lower connecting member 22 .

[0075] Preferably, magnetic members are provided in both the sleeve rod 51 and the upper connecting member 12 , and the sleeve rod 51 is fixed to the upper connecting member 12 by being attracted by the magnetic members.

[0076] Furthermore, a sliding hole is provided at the right end of the sleeve rod 51, which slides with the upper connecting member 12 of the rod-shaped structure, so that the sleeve rod 51 can be slid up and down along the upper connecting member 12. When it is necessary to use the angle fixing assembly 50 to fix the upper connecting member 12 and the lower connecting member 22, it can slide down along the upper connecting member 12 toward the sleeve rod 51 until the left end of the sleeve rod 51 is stuck between the two ends of the lower connecting member 22 of the U-shaped structure. At this time, the left end of the sleeve rod 51 can be locked and fixed using the fixing member 52. In this way, the upper connecting member 12 and the lower connecting member 22 can be maintained in the corresponding state, and thus the two can also be maintained at the corresponding angle, which facilitates measurement using the angle measuring member 30.

[0077] Advantageously, in some other embodiments of the present invention, the angle measuring member 30 is slidably disposed on the lower connecting member 22 .

[0078] The angle measuring member 30 can be fixed to the lower connecting member 22 by magnets. In this way, the angle measuring member 30 can be removed from the lower connecting member 22, or can be slid up and down along the lower connecting member 22 to adjust its position. When in use, the angle measuring member 30 can be moved to the position where the upper connecting member 12 and the lower connecting member 22 intersect, thereby ensuring the accuracy of the measurement.
