Description

Technical Field

[0001] The present invention relates to the technical field of surgical instrument contamination detection, and particularly to a method and system for analyzing the contamination data of the residues of a surgical instrument reamer. Background Art

[0002] In the field of orthopedic surgery, as a key preprocessing instrument before implanting implants, the reamer undertakes the important mission of precise reaming. Through the carefully arranged threads and grooves on the surface, the reamer realizes the progressive expansion of the patient's medullary cavity during high-speed rotation. However, although the thread structure in the reamer can improve the surgical efficiency, at the same time, during rotation, while the thread structure provides a gripping force, its deep grooves also become areas where blood, bone chips, and biofilms are easily adhered to and embedded.

[0003] When analyzing the contamination of surgical instruments in the prior art, surgical instruments such as reamers are often regarded as homogeneous rigid bodies, only considering the assessment of the contamination risk on the surface of the instruments, but often ignoring the hiding of contaminants caused by the unique structure of the reamer, without considering the mechanical embedding effect of bone chips and biological tissues in the spiral threads. At the same time, the prior art also lacks relevant analysis of the internal relationship between the functional structure of the reamer and the mechanism of its contamination generation, making its contamination risk assessment plan unable to adapt to the special structure of the reamer, ultimately resulting in the inability to comprehensively assess the contamination risk, thus affecting the timely replacement of surgical instruments during use, slowing down the surgical progress of patients, and increasing the risk of cross-infection.

[0004] To solve these problems, the present application designs a method and system for analyzing the contamination data of the residues of a surgical instrument reamer. Summary of the Invention

Without conflict, the technical features in the embodiments of the present invention and the embodiments can be combined with each other.

[0050] Embodiment 1

[0051] As Figure 1 shown, this embodiment provides a method for analyzing the residue pollution data of a surgical instrument, a medullary cavity reamer, which specifically includes the following steps:

[0052] S1. Obtain the spiral structure data and intraoperative operation data of the medullary cavity reamer, and at the same time obtain the residue detection data of the medullary cavity reamer;

[0053] S2. Analyze the degree of structural pollution intrusion of the medullary cavity reamer based on the spiral structure data and the residue detection data;

[0056] S5. Carry out a replacement warning for the medullary cavity reamer according to the evaluation result of the residue pollution risk of the medullary cavity reamer.

[0057] In a preferred technical solution of the present invention, as Figure 2 shown, in step S2, based on the spiral structure data and the residue detection data, the degree of structural pollution intrusion of the reamer is analyzed, including the following specific steps:

[0058] S21. Extract the spiral structure data and the residue detection data of the reamer;

[0059] S22. Based on the spiral structure data and the residue detection data, analyze the degree of structural pollution intrusion of the reamer to obtain the analysis result of the degree of structural pollution intrusion of the reamer.

[0060] In a preferred technical solution of the present invention, step S22 includes the following specific steps:

[0061] S221. Based on the spiral structure data and the residue detection data, analyze the pollutant adhesion strength of the reamer to obtain the analysis result of the pollutant adhesion strength of the reamer. The surface roughness of the reamer will increase the actual contact area between the patient's medullary cavity and the reamer. At the same time, the hydrophobicity of the reamer surface will affect its droplet spreading ability, thereby affecting whether the pollutants will be detached from the reamer surface in time during the cleaning process. Therefore, in this step, the contact angle of the reamer is analyzed to quantify its hydrophobicity, the surface roughness of the reamer is analyzed to quantify its actual contact area with the patient's medullary cavity and the degree of easy retention of pollutants, and the concentration of the residue is quantified to analyze the adhesion difference of the pollutants during the intraoperative operation, so as to realize the analysis of the influence of the surface characteristics of the reamer material on the pollutant adhesion; the pollutant adhesion strength calculation formula is: , where Zf is the pollutant adhesion strength of the reamer, Co is the initial residue concentration of the reamer in the residue detection data, C is the current residue concentration of the reamer in the residue detection data, R is the surface roughness of the contact surface between the reamer and the patient in the spiral structure data, is the contact angle of the contact surface between the reamer and the patient in the spiral structure data;

[0062] S222. Analyze the embedding strength of pollutants in the grooves of the reamer based on the spiral structure data and the residue detection data, and obtain the analysis result of the embedding strength of pollutants in the grooves of the reamer. The thread clearance and depth of the reamer will affect the residence time of bone chips, biological tissues, and blood generated during the operation in the grooves. The viscosity of the residue (in this embodiment, the viscosity of the patient's blood measured by a rheometer will be used as the viscosity of the residue) and the rotation speed of the reamer during the advancement in the operation will affect the embedding state of pollutants in the grooves of the reamer. Therefore, in this step, based on the diffusion-convection equilibrium theory, the Strouhal number is introduced to quantify the embedding strength of pollutants in the grooves of the reamer. The calculation formula for the embedding strength of pollutants in the grooves of the reamer is: , where Gc is the embedding strength of pollutants in the grooves of the reamer, d is the thread depth of the reamer in the spiral structure data, g is the thread clearance of the reamer in the spiral structure data, u is the viscosity of the residue in the residue detection data, p is the density of the residue in the residue detection data, and vt is the average rotation speed of the reamer;

[0063] S223. Analyze the degree of structural pollution intrusion of the reamer based on the analysis result of the pollutant adhesion strength of the reamer and the analysis result of the embedding strength of pollutants in the grooves of the reamer, and obtain the analysis result of the degree of structural pollution intrusion of the reamer. In this step, by comprehensively considering the pollutant adhesion strength and the embedding strength of pollutants in the grooves of the reamer, the pollution persistence is quantified, thereby realizing the analysis of the degree of structural pollution intrusion of the reamer. The calculation formula for the degree of structural pollution intrusion of the reamer is: , where Jq is the degree of structural pollution intrusion of the reamer, and a1 and a2 are the influence weights of the pollutant adhesion strength and the embedding strength, respectively.

[0064] In the preferred technical solution of the present invention, as Figure 3 shown, in step S3, based on the spiral structure data and the intraoperative operation data, analyze the dynamic pollution load degree of the reamer, including the following specific steps:

[0065] S31. Extract the spiral structure data and the intraoperative operation data of the reamer;

[0066] S32. Analyze the dynamic pollution load degree of the reamer based on the spiral structure data and the intraoperative operation data, and obtain the analysis result of the dynamic pollution load degree of the reamer.

[0067] In the preferred technical solution of the present invention, step S32 includes the following specific steps:

[0068] S321. Analyze the dynamic deposition degree of contaminants in the reamer based on the spiral structure data and intraoperative operation data, and obtain the analysis result of the dynamic deposition degree of contaminants in the reamer. This step analyzes the driving force for contaminant deposition provided by the mechanical work of the reamer, thereby realizing the quantification of the growth of the dynamic deposition degree of contaminants in the reamer during the intraoperative operation. The formula for calculating the dynamic deposition degree of contaminants in the reamer is as follows: , where Dc is the dynamic deposition degree of contaminants in the reamer, F is the axial pressure of the reamer at the t-th moment during the operation in the intraoperative operation data, Fmax is the maximum axial pressure of the reamer in the intraoperative operation data, w is the rotation speed of the reamer at the t-th moment during the operation in the intraoperative operation data, t is the operation duration of the reamer in the intraoperative operation data, D is the diameter of the reamer in the spiral structure data, and Ds is the diameter of the patient's medullary cavity in the intraoperative operation data;

[0069] S322. Analyze the degree of bone chip tissue contamination in the reamer based on the spiral structure data and intraoperative operation data, and obtain the analysis result of the degree of bone chip tissue contamination in the reamer. The degree of bone calcification of the patient can reflect the brittleness of their bone tissue. When the reamer acts on the patient's bone tissue, the greater the brittleness, the easier it is to generate bone chips due to bone tissue fragmentation, thereby further contaminating the reamer. Therefore, this step analyzes the interaction between the degree of bone tissue calcification of the patient and the mechanical force of the reamer during the intraoperative operation, thereby realizing the analysis of the change in the degree of bone chip tissue contamination in the reamer during the intraoperative operation. The formula for calculating the degree of bone chip tissue contamination in the reamer is as follows: , where Gx is the degree of bone chip tissue contamination in the reamer, Ca is the degree of bone tissue calcification of the patient obtained through imaging examination in the intraoperative operation data, and Camax is the critical value of complete bone tissue calcification;

[0070] S323. Analyze the dynamic pollution load degree of the reamer according to the analysis result of the dynamic deposition degree of contaminants in the reamer and the analysis result of the degree of bone chip tissue contamination, and obtain the analysis result of the dynamic pollution load degree of the reamer. This step integrates the dynamic deposition degree of contaminants caused by intraoperative operation parameters and the degree of bone chip tissue contamination caused by the patient's bone quality characteristics as two sources of pollution, and realizes the quantification of the progressive cumulative characteristics of intraoperative pollution of the reamer. The formula for calculating the dynamic pollution load degree of the reamer is as follows: , where Fh is the dynamic pollution load degree of the reamer, and b1 and b2 are the influence weights of the dynamic deposition degree of contaminants and the influence weight of the degree of bone chip tissue contamination, respectively.

[0071] In a preferred technical solution of the present invention, in step S4, according to the analysis results of the structural pollution intrusion degree and the dynamic pollution load degree of the reamer, the pollution risk of the reamer residue is evaluated, including the following specific steps:

[0072] S41. Extract the analysis results of the structural pollution intrusion degree and the dynamic pollution load degree of the reamer obtained by analysis;

[0073] S42. Based on the analysis results of the structural pollution intrusion degree and the dynamic pollution load degree of the reamer, evaluate the pollution risk of the reamer residue to obtain the pollution risk evaluation result of the reamer residue. In this step, the analysis results of the structural pollution intrusion degree and the dynamic pollution load degree of the reamer are used as the main pollution sources of the reamer residue for analysis, and the pollution risk is comprehensively evaluated. The evaluation formula for the pollution risk of the reamer residue is: , where Qx is the pollution risk of the reamer residue, V is the volume cut by the reamer per revolution, d is the thread depth of the reamer, and c1 and c2 are the influence weights of the structural pollution intrusion degree and the dynamic pollution load degree respectively.

[0074] In a preferred technical solution of the present invention, in step S5, according to the pollution risk evaluation result of the reamer residue, a reamer replacement warning is carried out, including the following specific steps:

[0075] S51. Obtain the pollution risk evaluation result of the reamer residue obtained by evaluation;

[0076] S52. Preset a pollution risk threshold. When the pollution risk evaluation result of the reamer residue is less than the pollution risk threshold, a reamer replacement warning is carried out. It should be noted that the acquisition method of the set parameters (such as weights and thresholds) in this embodiment is obtained by experiments by those skilled in the art. The specific experimental method is: obtain the spiral structure data and intraoperative operation data of multiple historical reamers, and at the same time obtain the residue detection data and cleaning operation data of the corresponding reamers, substitute them into each step of this embodiment to evaluate the pollution risk of the residues of multiple historical reamers, and at the same time obtain the judgment results of the pollution risk of the residues of multiple historical reamers, and import the judgment results of the pollution risk of the residues of multiple historical reamers and the pollution risk evaluation results of the residues of multiple historical reamers obtained by each step into the fitting software for continuous fitting to obtain the values of the set parameters (such as weights and thresholds) that meet the maximum pollution risk judgment accuracy rate.
