Background
Currently, the optical navigation technology and the medical imaging technology are combined and widely applied to the robot navigation operation. Tracers designed based on this technique may be mounted intraoperatively on the robotic arm, surgical tool, and body in the vicinity of the patient's surgical site to determine the respective spatial locations for registration. The tracer on the mechanical arm and the operation tool is connected with the rigid structure, so that reliable installation and stable position can be realized. The tracer installed on the patient body is generally fixed by connecting the tracer base with the bone in a drilling screwing or clamping mode and then transferring the tracer.
However, despite the rigidity of the bone, it is far from a metallic structure and does not completely avoid excessive movements due to weak installation or external forces. Excessive displacement may occur at the position where the tracer base is clamped with the bone, may also occur at the intermediate transfer point, and may also be a comprehensive effect of multiple factors, when facing some relatively precise operations, the excessive displacement of the tracer is often not easily found, and once the tracer is excessively displaced, the accuracy of the registration position is completely lost, the mechanical arm will not be navigated to the correct position, and the position where the subsequent operator performs the operation will be completely wrong, thereby affecting the accuracy of the operation and even threatening the life safety of the patient.
Therefore, how to timely judge whether the position of the tracer moves excessively, so as to ensure the accuracy of the operation is a problem to be solved urgently.

Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present specification more apparent, the technical solutions of the present specification will be clearly and completely described below with reference to specific embodiments of the present specification and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present specification. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
In the robot navigation surgery, an operator usually needs to fix a tracer on bone tissue in a patient body, so as to obtain the relative position of a surgical instrument and a diseased part, and further generate a navigation path of minimally invasive surgery equipment, so as to perform surgery on the diseased part, however, in the surgery process, the situation that the tracer base is not firmly installed or the tracer is excessively moved due to external force action usually occurs, so that the surgical navigation path is also deviated from the actual diseased part of the patient, as shown in fig. 1 and 2.
Fig. 1 is a schematic diagram showing the offset between the connection of the tracer and the base.
When the tracer receives the action of external force, because the connection point of the tracer and the tracer base is fixed infirm, the tracer is deflected.
Fig. 2 is a schematic diagram of a tracer base offset provided in the present specification.
When the tracer is acted by external force, the tracer is deviated due to the fact that the base of the tracer is not firmly fixed with bone tissue in the patient.
Currently, in order to solve the above-mentioned situation, an additional offset monitor tracer is usually driven into bone tissue in a patient, and according to the relative positions of the offset monitor tracer and the tracer in the patient, it is determined whether the tracer in the patient is excessively offset, as shown in fig. 3.
Fig. 3 is a schematic diagram of tracer offset monitoring provided in the present specification.
Wherein, the offset monitoring tracer has no connecting structure and only has one optical positioning mark, and is fixed on bone tissue in a patient body in a nailing mode. However, while driving an additional offset tracer into the patient can detect whether the tracer in the vicinity of the diseased site is excessively offset, fixing the offset tracer tends to cause additional trauma to the patient's body.
In order to monitor whether the tracer is deviated or not on the premise of avoiding extra trauma to a patient and ensure the accuracy of the operation, the technical schemes provided by the embodiments of the specification are described in detail below with reference to the accompanying drawings.
Fig. 4 is a schematic view of a surgical tracing apparatus provided in the present specification.
The present specification provides a surgical tracing apparatus, as shown in fig. 1, comprising: the system comprises a tracer, a signal transmitter and a signal sensor.
The tracer is fixed on bone tissue in a patient body through the tracer base, and when the tracer base is fixed, in order to enable the position of the tracer to be more stable, operators need to perform minimally invasive opening at the position near the diseased part of the patient body, place the tracer base in the wound and fix the tracer base on the bone tissue in the wound.
In particular, there are various ways of fixing the tracer base, for example, by fixing the tracer base to the bone tissue in the wound by a clamping device of the tracer base, and for example, by drilling the bone tissue in the wound and fixing the tracer base to the bone tissue in the wound by a screw.
In order to avoid the influence of the fixed position of the tracer on the operation on the affected part, the operator can perform a minimally invasive opening on the position near the affected part of the patient, so that the tracer can be placed on other bone tissues near the affected part of the patient.
Before performing an operation on a patient, operators generally need to install tracers in a preset range of a diseased part of the patient and on a surgical instrument respectively to determine the relative position between the diseased part of the patient and the surgical instrument, wherein in order to accurately determine the relative position and the angular relationship between the diseased part of the patient and the surgical instrument, each tracer can be provided with at least three positioning light source marks, the relative positions among the positioning light source marks are fixed, the positioning light source marks can be optical mark balls such as infrared light emitting devices, light emitting diodes (LIGHT EMITTING Diode, LEDs) or passive reflecting spheres, the positions of each tracer are acquired through optical positioning devices arranged in an operation environment, and the relative position and the angular relationship between each tracer are determined, so that the relative position and the angle of the diseased part of the patient and the surgical instrument are obtained, and then the navigation path of the operation is planned, so that minimally invasive operation equipment performs operation according to the navigation path, and provides reference for the operators to perform operation on the patient.
The tracer is provided with a signal emitter for providing a signal to a signal sensor, and for ease of understanding, the present disclosure provides a schematic diagram of the tracer, as shown in fig. 5.
FIG. 5 is a schematic diagram of a tracer according to the present disclosure, in which
The tracer is connected to the tracer base, is fixed on the vertebra in the patient body through the tracer base, is fixed with location light source mark and signal transmitter on the tracer.
The signal inductor can be fixed on the patient skin in the preset range of the tracer through the medical adhesive, so that the signal inductor and the patient skin cannot move relatively, the operator can further fix the signal inductor on the patient skin in the preset range of the tracer through the medical adhesive through the medical bandage, the signal inductor is reinforced on the patient skin, and further fixation of the signal inductor and the patient skin is realized.
Because the fixed position of the signal sensor can be very close to the tracer and is fixed by the medical glue and the medical bandage, even if the relative position of the signal sensor and the tracer moves relatively, the small change of the movement can not influence the navigation path of the operation.
It should be noted that, the positions of the signal transmitter on the tracer and the tracer base are relatively fixed, once the relative positions of the signal transmitter and the tracer base change, the signal provided by the signal generator received by the signal sensor will change, and at this time, the signal transmitter needs to be re-fixed on the tracer and the surgical navigation path needs to be re-calibrated.
Of course, the control personnel can also fix the signal sensor on the skin of the patient in an adsorption mode through the vacuum adsorption device, fix the signal sensor on the skin of the patient in a preset range of the tracer through the medical bandage, strengthen the signal sensor on the skin of the patient, and further fix the signal sensor and the skin of the patient, thereby preventing the signal sensor and the skin of the patient from generating relative movement.
In practical application, the signal transmitter fixed on the tracer can be the laser transmitter, and correspondingly, the signal sensor can be the laser sensor that can receive laser transmitted by the laser transmitter, is equipped with the photoelectric detector that can convert the laser transmitted by the laser transmitter of receiving into the signal of telecommunication that can be responded to by the laser sensor on the laser sensor, like four-quadrant photoelectric detector, of course, also can be equipped with other photoelectric detectors that can convert the laser transmitted by the laser transmitter of receiving into the signal of telecommunication that can be responded to by the laser sensor on the laser sensor, and this specification does not limit for this.
After the tracer is fixed on the patient body by the operator, the angle of the laser transmitter on the tracer can be adjusted, so that laser emitted by the laser transmitter is aligned to a preset position range in the center of the sensing area of the laser sensor, and is irradiated to the center position of the sensing area of the laser sensor as much as possible, wherein the preset position range in the center of the sensing area of the laser sensor can be set according to actual conditions, and the specification is not limited in this way.
After the angle of the laser emitter is adjusted, the relative position of the surgical instrument and the diseased part can be determined through the optical positioning device in the surgical environment, so that the surgical path of the minimally invasive surgical equipment is navigated, surgical reference is provided for operators, and the surgery on the diseased part is performed. In the operation process, the situation that the positioning light source mark on the tracer is deviated due to the fact that the base of the tracer is not firmly installed or excessive movement caused by external force action occurs, so that the operation navigation path is deviated from the actual diseased part of the patient. In order to avoid excessive deflection of the tracer, whether the tracer is excessively deflected or not can be judged according to the irradiation position of laser emitted by the laser emitter to the laser sensor on the sensing area of the laser sensor. If the irradiation position of the laser emitted by the laser emitter to the laser sensor on the sensing area is within a set position range, the offset distance of the tracer is indicated to not exceed a preset threshold value, and if the irradiation position of the laser emitted by the laser emitter to the laser sensor on the sensing area is outside the set position range, the offset distance of the tracer is indicated to exceed the preset threshold value, wherein the set position range can be set according to practical situations, and the specification is not specifically described.
In addition, the signal transmitter arranged on the tracer can also be a magnetic field generator provided with a magnetic probe, correspondingly, the signal sensor can be a magnetic field sensor capable of measuring the magnetic field generated by the magnetic field generator, a magnetic field measuring instrument (such as a magnetic field measuring instrument) capable of measuring the magnetic field intensity is arranged on the magnetic field sensor, when the magnetic field sensor monitors that the change amount of the magnetic field generated by the magnetic field generator exceeds a preset change amount, the deviation distance of the tracer exceeds a preset threshold value, wherein the preset change amount can be set according to actual conditions, and the specification is not limited to the change amount.
Specifically, the signal sensor and the tracer can be connected with an external power supply through an external power line, so that a required power supply is provided for the signal sensor, the signal transmitter and the positioning light source mark.
In this specification, be provided with the skew alarm that is connected with signal sensor, when signal sensor monitors the skew distance of tracer and surpasses the default threshold value, can report to the police through the skew alarm, the navigation route of explanation current moment operation takes place the skew, in order to guarantee operation safety, the control personnel need stop current operation, and according to the light that the locating light source mark on the tracer that minimally invasive surgery equipment and take place the skew launched or reflected, through the relative position between disease position and the surgical instrument of redetermining the disease, or the mode of adjustment tracer angle and fixed position, calibrate the operation navigation route of minimally invasive surgery equipment, thereby ensure operation accuracy.
Because the operator often can be unavoidable to the health near tracer fixed position in the in-process of carrying out the operation to disease position of disease, in order to carry out operation, these effort can lead to disease's health to take place deformation in the short time, and then arouse the skew position of tracer to surpass the preset threshold value, but after the effort that exerts the health to the disease disappears, the tracer also can resume original position, and the skew position of tracer can get back to in the preset threshold value this moment, indicates that the operation navigation route does not take place skew this moment.
Therefore, in order to reduce the occurrence of false alarm of the offset alarm, the signal sensor can judge whether the alarm is needed according to the time period for the offset position of the tracer to exceed the preset threshold value. If the offset distance of the tracer exceeds the preset threshold value for a period of time not exceeding the preset time, the tracer is indicated to be not offset, or the tracer is offset to return to the original position within the preset time after being offset, and the operation navigation path for the diseased part is still accurate at the moment. In other words, if the tracer does not shift, or the tracer shifts back to the original position within a preset time length after the tracer shifts, the surgical navigation path at the moment can still be used for performing surgical navigation on the minimally invasive surgical equipment, so that calibration of the surgical navigation path of the minimally invasive surgical equipment is not needed, and therefore, no alarm is needed, and only when the time length that the shift distance of the tracer exceeds the preset threshold exceeds the preset time length, the surgical navigation path is indicated to shift from the diseased part of the patient, the alarm is given out through the shift alarm, and calibration of the surgical navigation path for the diseased part is performed again, wherein the preset time length can be set according to actual conditions, and the specification is not particularly limited.
In order to facilitate understanding of the above surgical tracing apparatus, the present disclosure further provides a method flowchart of a surgical navigation path to illustrate a method for performing a surgical navigation path during an actual surgical procedure by using the above surgical tracing apparatus, as shown in fig. 6.
Fig. 6 is a flow chart of a method for providing a surgical navigation path in the present specification, which includes the following steps:
s601: the tracer is fixed on bone tissue within a preset range of the affected part of the patient.
The operator performs a minimally invasive opening near the affected part of the patient, places the tracer base in the wound, and fixes it to the bone tissue in the wound.
S602: the signal sensor is fixed on the skin of a patient within a preset range of the tracer.
The control personnel fix the signal inductor on the patient skin within the preset range of the tracer through medical glue, so that the signal inductor is as close to the tracer as possible, and the signal inductor is reinforced through a medical bandage.
S603: and determining a surgical navigation path of the minimally invasive surgical equipment according to the positioning light source mark on the tracer, and controlling the minimally invasive surgical equipment to perform surgery on the diseased part according to the surgical navigation path.
The optical positioning device determines the relative positions of the positioning light source marks through the positioning light source marks on the tracer, and further determines the relative positions of the surgical instrument and the diseased part of the patient.
S604: monitoring whether the offset distance of the tracer exceeds a preset threshold.
And the signal sensor judges whether the offset distance of the tracer exceeds a preset threshold value according to the signal provided by the signal transmitter to the signal sensor.
S605: and if the time length that the offset distance of the tracer exceeds the preset threshold exceeds the preset time length, alarming through the offset alarm, and calibrating the operation navigation path aiming at the diseased part again.
If the time length that the offset distance of the tracer exceeds the preset threshold exceeds the preset time length, the surgical navigation path aiming at the diseased part is calibrated again through the light rays emitted or reflected by the positioning light source marks on the minimally invasive surgical equipment and the offset tracer.
According to the method, in the process of performing an operation on a patient, the signal sensor can be fixed on the premise that no additional wound is added to the patient body, whether the tracer is excessively deviated or not is monitored in real time through the signal sensor, and once the tracer is excessively deviated, an alarm is given out through the deviation alarm, so that an operator can position light rays emitted or reflected by the light source marks on minimally invasive operation equipment and the deviated tracer, calibrate the operation navigation path aiming at the diseased part again, and the trauma to the patient body is reduced while the accuracy of the operation navigation path is ensured.
