[0002] The spine plays a role in load-bearing, protecting the spinal cord, and performing small-range movements in the human body. Maintaining the stability of the spinal structure is crucial for its function. With the aggravation of aging, the incidence rate in the spinal field is getting higher and higher. For example, spinal diseases such as spinal tumors, spinal traumas, degenerative diseases, and spinal deformities all endanger human health and show a trend of getting younger. In spinal osteotomy surgery, currently, a titanium mesh is usually implanted to replace the osteotomized vertebral body, and a titanium mesh of appropriate length is used to protect the spinal cord and support the normal upper and lower spines.

[0032] The present invention provides a titanium mesh length measuring device for spinal osteotomy.

[0033] As Figures 1 to 3 shown, a titanium mesh length measuring device for spinal osteotomy includes a surgical forceps 1, a measuring structure 2, a display structure 3, a controller, and two probes 4; the surgical forceps 1 includes a handheld part and two clamping arms 12, and one of the probes 4 is detachably arranged on one of the clamping arms 12, and the other probe 4 is detachably arranged on the other clamping arm 12. The end of each probe 4 away from the surgical forceps 1 is a measuring end 43, and the handheld part is used to control the movement of the two clamping arms 12 to adjust the distance between the two measuring ends 43; the controller is electrically connected to the measuring structure 2 and the display structure 3, and the measuring structure 2 and the display structure 3 are respectively arranged on the surgical forceps 1. The measuring structure 2 is used to detect the measurement data of the straight-line distance between the two measuring ends 43 and send it to the controller; the display structure 3 is used to display the measurement data.

[0034] The measuring structure 2 enters the osteotomy site through the probe 4 for measurement, and then the corresponding measurement data is displayed through the display structure 3, so that medical staff have accurate cutting data when cutting the titanium mesh, which accelerates the cutting efficiency of medical staff.

[0035] The measuring structure 2 includes a tension sensor 21 and an elastic cable 22; the handheld part includes two gripping arms 11, and an adjustment space 13 is formed between the two gripping arms 11. The tension sensor 21 is arranged on one side of one of the gripping arms 11 facing the adjustment space 13. One end of the elastic cable 22 is connected to the tension sensor 21, and the other end of the elastic cable 22 is connected to the other gripping arm 11; the controller is electrically connected to the tension sensor 21, and the controller is used to calculate the measurement data between the two measuring ends 43 extending into the osteotomy site according to the tension data detected by the tension sensor 21. By spreading the two gripping arms 11 so that the measuring ends 43 extend into the position to be detected at the osteotomy site, at this time the tension sensor 21 is subjected to a certain tension. Since the opening and closing angle of the surgical forceps 1, as well as the lengths of the clamping arms 12 and the probes 4 are preset, the controller can judge the angle between the two clamping arms 12 according to the tension. Under the condition that the probes 4 and the clamping arms 12 are of fixed length, the controller can quickly calculate the straight-line length between the two measuring ends 43 according to trigonometric functions.

[0036] At one end of each probe 4 away from the surgical forceps 1, a mounting seat 45 is provided. A detection space 14 is formed between the two measurement ends 43. On one side of each mounting seat 45 facing the detection space, a camera 18 is provided. Each camera 18 is electrically connected to a controller. The camera 18 is used to capture image data of the spinal cord occlusion area at the osteotomy site and send it to the controller. The surgical forceps 1 are also provided with a communication module. The controller is electrically connected to the communication module. The controller is used to transmit the image data to an external display device through the communication module.

[0037] Specifically, the two mounting seats are arranged staggeredly. This can avoid mutual shooting interference between the two cameras and ensure the shooting effect.

[0038] Specifically, the mounting seat 45 is a circular plate, and the probe 4 is connected to the outer edge of the circular plate. This can prevent sharp segments from contacting the osteotomy site.

[0039] Specifically, the controller is also used to establish a model of the osteotomy site based on each measurement data and each image data, and then form a titanium mesh model for supporting the osteotomy site according to the model, and mark each data of the titanium mesh model and send it to the external display device for display. This can facilitate the comparison of the finished titanium mesh after cutting by the user and leave detailed data on the establishment of the titanium mesh.

[0040] The display structure 3 includes a control button 31 and a light bar 32. The light bar 32 is arranged on one of the clamping arms 12 and is arranged along the extension direction of the clamping arm 12. The light bar 32 includes a number of light source blocks, and each light source block is arranged in sequence along the extension direction of the light bar 32. The light source block is used to represent the measurement data. The controller is electrically connected to the control button 31 and the light bar 32 respectively. The controller is used to control the number of light source blocks that are lit from the handheld part to the probe 4 direction in sequence according to the measurement data. The control button 31 is used to send a control signal to the controller to enable the controller to control the state of each lit light source block. A cutting space is formed between the two clamping arms 12. On one side of the clamping arm 12 facing the cutting space, a cutting edge is provided. The two cutting edges are used to cooperate to cut the titanium mesh. The design of the light bar 32 in cooperation with the cutting edge enables medical staff to directly cut the titanium mesh according to the light bar 32 without the need to rely on other measuring devices.

[0041] Specifically, a single light source block represents a distance of 1 mm.

[0042] Specifically, the control button 31 is used to send a recording command and an elimination command to the controller respectively. When the controller receives the recording command, the controller controls the number of light source blocks lit in the light bar 32 according to the current measurement data, so that the lit light source blocks remain in the normally open state. Medical staff determine the length to be cut by comparing the length of the light source blocks. When the controller receives the elimination button, the controller will control the normally open light source blocks to turn off, so that new data can be detected again.

[0043] Specifically, the control button 31 is arranged on the handheld part, which facilitates the user to directly press the control button 31 during adjustment.

[0044] A limiting through hole 15 is formed on one side of one gripping arm 11 facing the adjustment space 13; a rack 5 is arranged between the two gripping arms 11. One end of the rack 5 is hinged to the gripping arm 11 far from the limiting through hole 15, and the other end of the rack 5 passes through the limiting through hole 15. A limiting tooth 16 is arranged on the side of the limiting through hole 15 facing the teeth of the rack 5. The rack 5 is used to move along the opening direction of the limiting through hole 15 so that the limiting tooth 16 meshes with the rack 5 to fix the relative distance between the two gripping arms 11. By lifting the end of the rack 5 far from the hinged part with a finger, the rack 5 is separated from the limiting tooth 16, and the relative distance between the two gripping arms 11 is adjusted, thereby adjusting the detection distance. This facilitates the medical staff to operate the surgical forceps 1 with one hand. When the detection distance is appropriate, the rack 5 is pressed down so that the rack 5 meshes with the limiting tooth 16 to fix the relative distance between the two gripping arms 11, and then the control button 31 is pressed for detection, which can avoid damage to the osteotomy site caused by the force of the two clamping arms 12 approaching when the button is pressed.

[0045] Anti-slip grooves 17 are respectively arranged on the sides of the two gripping arms 11 facing away from the adjustment space 13. The anti-slip grooves 17 can prevent the surgical forceps 1 from falling off.

[0046] External threads are arranged at one end of the probe 4 close to the surgical forceps 1, and a first connector 44 electrically connected to the camera is arranged at the end of the probe 4 with external threads; a connecting screw hole is formed at one end of the clamping arm 12 far from the handheld part, and a second structure electrically connected to the controller is arranged at the bottom of the connecting screw hole. The probe 4 is threadedly connected to the clamping arm 12 to electrically connect the first connector 44 and the second connector. The threaded connection between the probe 4 and the clamping arm 12 facilitates the replacement of the probe 4 and the maintenance of the camera 18.

[0047] Specifically, the length of the probe 4 is between 15 cm and 10 cm, which can prevent the clamping arm 12 from entering the osteotomy site.

[0048] The probe 4 includes a connecting rod 41 and a detecting rod 42. One end of the connecting rod 41 is connected to one end of the detecting rod 42, a measuring end 43 is arranged at the end of the detecting rod 42 far from the connecting rod 41, and a first connector 44 is arranged at the end of the connecting rod 41 far from the detecting rod 42. An obtuse angle is formed between the connecting rod 41 and the detecting rod 42. The detecting rod 42 is inclined, which facilitates the detecting rod 42 to extend into the inner side of the osteotomy site and the position of the spinal cord occlusion, facilitating the medical staff to obtain detailed data of the osteotomy site.

[0049] Specifically, one connecting rod 41 is parallel to one clamping arm 12, and the other connecting rod 41 is parallel to the other clamping arm 12.

[0050] The two detection rods 42 are arranged in parallel; the obtuse angle between the connecting rod 41 and the probe 4 is 110° to 135°.

[0051] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
