Description

Technical Field

[0001] The present invention relates to the technical field of acupoint catgut embedding, and in particular to an intelligent catgut embedding device for acupoints. Background Art

[0002] With the development of traditional Chinese medicine such as acupuncture and massage, acupoint thread embedding therapy has become more and more widely used in clinical applications, and is used to treat various diseases and regulate the body. Traditional acupoint thread embedding operations mainly rely on the doctor's manual skills and experience. The operation process is complicated and requires high precision. There are differences in the operation levels of different doctors, resulting in uneven thread embedding effects. It is difficult for doctors to accurately control the puncture depth, force and thread embedding position through manual operation, and problems such as thread embedding position deviation and inaccurate depth are prone to occur. In addition, it is impossible to timely and accurately perceive the skin condition and resistance changes during the thread embedding process, resulting in unstable thread embedding effects.

[0003] Chinese patent application publication number: CN111773074A discloses an acupuncture thread embedding device, including a gun body, a needle tube, a driving mechanism, a needle core and a ventilation tube; the gun body includes a gun barrel and a handle connected to the lower part of the gun barrel, and a guide hole extending in the front-to-back direction is provided in the gun barrel; a piston cylinder is provided at the rear part of the needle tube, the piston cylinder is adapted to be in the guide hole, and the front end of the needle tube passes through the front end of the gun barrel; the driving mechanism is used to drive the piston cylinder to move back and forth along the guide hole; the needle core is inserted into the needle tube, and the rear end of the needle core is connected to a first piston, and the first piston is adapted to be in the piston cylinder; the ventilation tube is inserted into the guide hole on the rear side of the first piston, and the front end of the ventilation tube is connected to a second piston, which is adapted to be in the piston cylinder, and the second piston is provided with a first through hole connected to the ventilation tube, the rear end of the ventilation tube is fixed to the rear part of the gun body, and the rear part of the gun body is provided with a second through hole connected to the ventilation tube.

[0004] However, the existing technology has the following problems: the process of inserting the thread into the human body by the acupuncture thread embedding device is not monitored, and only the mechanical structure of the acupuncture thread embedding device is improved. Problems such as possible deviations in the acupuncture position cannot be solved, resulting in low efficiency of thread embedding positioning, and thus poor accuracy of thread embedding positioning. Summary of the Invention

[0005] To this end, the present invention provides an intelligent thread embedding device for acupoints, which is used to overcome the problem in the prior art that the process of the thread embedding device for acupoints being placed into the human body is not monitored, but only the mechanical structure of the thread embedding device for acupoints is improved. Problems such as possible deviations in the acupuncture position cannot be solved, resulting in low thread embedding positioning efficiency and thus poor thread embedding positioning accuracy.

[0006] To achieve the above-mentioned object, the present invention provides an intelligent acupuncture point embedding device, comprising:

[0014] A thrust compensation module is connected to the suture analysis module and is used to determine whether to increase the extension length of the flat-head needle based on the relative difference between the body fluid resistance oscillation coefficient and the preset body fluid resistance oscillation coefficient.

[0015] Furthermore, the invention also includes an automatic puncture mechanism, which includes a puncture needle arranged inside the gun barrel for embedding absorbable surgical suture into the acupuncture point, a thread clamp arranged on the inner side wall of the thread embedding gun body for inserting the absorbable surgical suture into the inner cavity of the puncture needle, a firing pin arranged at one end of the puncture needle for inserting the puncture needle into the human body, and a flat-headed thimble arranged on the firing pin for inserting the absorbable surgical suture into the human body;

[0016] The rotary knob is provided on the thread embedding gun body to control the target depth of the puncture needle.

[0017] Furthermore, the data analysis module determines that the puncture mode of the thread embedding device is the mild puncture mode based on a comparison result that the skin condition characterization parameter of the skin condition data is less than or equal to a preset skin condition characterization parameter.

[0018] Furthermore, the data analysis module determines that the puncture mode of the thread embedding device is the intensity puncture mode based on a comparison result that a skin condition characterization parameter of the skin condition data is greater than a preset skin condition characterization parameter.

[0019] Furthermore, the data analysis module determines that the puncture needle has a position deviation and the puncture needle puncture position depth is insufficient based on the comparison result that the resistance change rate of the resistance data encountered by the striker in the process of pushing the puncture needle is less than or equal to the first preset resistance change rate.

[0020] Further, the adjustment module determines to increase the striker extension length by a preset length increase coefficient based on a comparison result that the ratio of the resistance change rate to the first preset resistance change rate is less than or equal to the preset ratio;

[0021] The adjustment module determines to increase the scale of the rotary knob by a preset scale increase coefficient based on a comparison result that a ratio of the resistance change rate to a first preset resistance change rate is greater than a preset ratio.

[0022] Furthermore, the data analysis module determines that the puncture needle has a position deviation and the puncture needle puncture position depth is too deep based on the comparison result that the resistance change rate of the resistance data encountered by the striker in the process of pushing the puncture needle is greater than the second preset resistance change rate.

[0023] Furthermore, the adjustment module determines to reduce the striker extension length by a preset length reduction coefficient based on a comparison result that a difference between the resistance change rate and the second preset resistance change rate is less than or equal to a preset difference;

[0024] The adjustment module determines to increase the scale of the rotary knob by a preset scale reduction coefficient based on a comparison result that a difference between the resistance change rate and a second preset resistance change rate is greater than a preset difference.

[0025] Furthermore, the suture analysis module determines that the absorbable surgical suture pre-placement process is unqualified based on the comparison result that the resistance wire slip index of the absorbable surgical suture gently pushed by the flat-headed needle for a preset length is greater than the preset wire slip index, and determines that there is body fluid that hinders the absorbable surgical suture pre-placement process based on the comparison result that the body fluid resistance oscillation coefficient during the absorbable surgical suture pre-placement process is greater than the preset body fluid resistance oscillation coefficient.

[0026] Furthermore, the thrust compensation module determines to increase the flat-head thimble extension length by a first preset flat-head thimble adjustment coefficient based on a comparison result that a relative difference between the body fluid resistance oscillation coefficient and a preset body fluid resistance oscillation coefficient is less than or equal to the preset relative difference;

[0027] The thrust compensation module determines to increase the flat head ejector extension length by a second preset flat head ejector adjustment coefficient based on a comparison result that a relative difference between the body fluid resistance oscillation coefficient and a preset body fluid resistance oscillation coefficient is greater than the preset relative difference.

[0028] Compared with the prior art, the beneficial effect of the present invention is that the present invention controls the target depth of the puncture needle by rotating the knob. After pulling the trigger, the detection mechanism collects skin status and resistance data, the data analysis module determines the puncture mode and judges whether the puncture needle is deviated, the adjustment module adjusts the puncture depth, the suture analysis module and the thrust compensation module ensure that the absorbable surgical suture is smoothly inserted and compensates for unqualified conditions, accurately controls the puncture depth, and the scale design of the rotating knob is accurately adjusted according to the acupuncture points and patient conditions to avoid being too deep or too shallow, thereby improving the treatment effect, automatically determining the puncture mode, judging deviations and adjusting, reducing human errors, ensuring that the absorbable surgical suture is accurately inserted into the acupuncture points, improving the needle insertion efficiency, improving the thread embedding positioning efficiency, and thus improving the thread embedding positioning accuracy.

[0029] Furthermore, the present invention determines the puncture mode through parameters characterizing the skin condition, and the striker strikes the puncture needle to the corresponding position according to the mode. The thread embedding depth is determined by rotating the knob scale. During the pushing process of the striker, the resistance change rate is analyzed and compared with the preset resistance change rate to determine whether the puncture needle deviates. The puncture mode is automatically selected according to the skin condition to avoid human judgment errors, improve the precise adaptability of the acupoint stimulation intensity, effectively reduce the risk of puncturing too deep or too shallow, and improve the accuracy of thread embedding positioning.

[0030] Furthermore, the present invention adjusts the puncture depth by the ratio of the resistance change rate to the first preset resistance change rate. When the puncture needle depth is too deep, the adjustment module adjusts according to the difference between the resistance change rate and the second preset resistance change rate, and automatically adjusts the depth according to the actual puncture situation to ensure that the absorbable surgical suture is accurately placed in the acupuncture point, enhances the adaptability of the thread embedding device, improves the thread embedding positioning efficiency, and thus improves the thread embedding positioning accuracy.

[0031] Furthermore, the present invention determines whether the pre-insertion process of the absorbable surgical suture is qualified through the thread slip index, and determines whether there is fluid obstruction when it is unqualified. In the case of obstruction, the thrust compensation module adjusts the extension length of the flat-head needle according to the relative difference, thereby improving the accuracy and stability of the absorbable surgical suture placement into the acupuncture point, and improving the accuracy of the treatment effect. The thread slip index and the fluid resistance oscillation coefficient are monitored in real time, and abnormal conditions in the absorbable surgical suture placement process are discovered in time, ensuring that the absorbable surgical suture can be smoothly placed into the acupuncture point, thereby improving the accuracy of thread embedding positioning.

[0044] The guiding mechanism 3 includes a spring guide seat slidably disposed on the guide rail 104 and a guide clamp 302 disposed on the spring guide seat for clamping the wire tube 201;

[0045] The automatic puncture mechanism 4 includes a puncture needle 401 disposed inside the gun barrel 101 for embedding absorbable surgical sutures into an acupuncture point, a thread clamp 402 disposed on the inner side wall of the thread embedding gun body 1 for inserting the absorbable surgical sutures into the inner cavity of the puncture needle 401, a firing pin 403 disposed at one end of the puncture needle 401 for inserting the puncture needle 401 into a human body, and a flat-headed thimble 404 disposed on the firing pin 403 for inserting the absorbable surgical sutures into a human body;

[0046] A rotary knob 5 is provided on the thread embedding gun body 1 to control the target depth of the puncture needle 401;

[0047] Detection mechanism 6, comprising a pressure sensor 601 disposed on the inner wall of the puncture needle tip for detecting skin condition data, and a strain gauge 602 disposed at one end of the flat-headed ejector pin 404 for detecting resistance data encountered by the flat-headed ejector pin 404 when pushing the absorbable surgical suture and by the striker 403 when pushing the puncture needle 401;

[0048] The control mechanism is arranged inside the wire embedding gun body and includes:

[0049] a data analysis module connected to the data acquisition module, configured to determine a puncture mode of the thread embedding device based on the skin condition characterizing parameter of the skin condition data, and to determine whether a position deviation of the puncture needle occurs based on a resistance change rate of the resistance data;

[0050] an adjustment module connected to the data analysis module, configured to determine and adjust the puncture depth of the puncture needle based on a ratio of the resistance change rate to a first preset resistance change rate, or based on a difference between the resistance change rate and a second preset resistance change rate;

[0051] a suture analysis module, connected to the data analysis module and the adjustment module, respectively, for determining whether the absorbable surgical suture pre-placement process is qualified based on a suture slippage index when the flat-head thimble gently pushes the absorbable surgical suture for a preset length, and determining whether body fluids hinder the absorbable surgical suture pre-placement process based on a body fluid resistance oscillation coefficient of an unqualified absorbable surgical suture pre-placement process;

[0052] A thrust compensation module is connected to the suture analysis module and is used to determine whether to increase the extension length of the flat-head needle based on the relative difference between the body fluid resistance oscillation coefficient and the preset body fluid resistance oscillation coefficient.

[0053] In an embodiment of the present invention, a driving motor 8 is also provided on the thread clamp 402, the striker 403, the flat-head ejector pin 404 and the spring guide seat 301; a button 7 is used to control the guide clamp 302 to clamp the wire tube 201 and transport it along the guide rail 104 to be parallel to the puncture needle 401. The thread clamp 402 places the absorbable surgical suture into the inner cavity of the puncture needle 401. At this time, the guide clamp 302 returns the wire tube 201 without the absorbable surgical suture along the guide rail 104 to the single wire tube warehouse 4.

[0054] Specifically, the present invention controls the target depth of the puncture needle by rotating the knob. After pulling the trigger, the detection mechanism collects skin status and resistance data. The data analysis module determines the puncture mode and judges whether the puncture needle is deviated. The adjustment module adjusts the puncture depth. The suture analysis module and the thrust compensation module ensure that the absorbable surgical suture is smoothly inserted and compensate for unqualified conditions, accurately controlling the puncture depth. The scale design of the rotating knob is accurately adjusted according to the acupuncture points and patient conditions to avoid being too deep or too shallow, thereby improving the treatment effect. The puncture mode is automatically determined, deviations are judged and adjusted, reducing human errors, ensuring that the absorbable surgical suture is accurately inserted into the acupuncture points, improving the needle insertion efficiency, improving the thread embedding positioning efficiency, and thus improving the thread embedding positioning accuracy.

[0055] In the embodiment of the present invention, the rotary knob is marked with scales of 0-5, the scale range is 0-5 cm, and the telescopic length of the puncture needle is controlled by the rotary knob.

[0056] In an embodiment of the present invention, the single wire tube magazine can accommodate multiples of 12 wire tubes, and when the wire tubes need to be replaced or loaded with absorbable surgical sutures, they are ejected by the button.

[0057] In the embodiment of the present invention, the grip adopts a classic pistol grip curve, and a non-slip silicone texture is added to the grip surface.

[0058] In an embodiment of the present invention, the trigger is triggered in two stages. When the pressure value applied to the trigger is less than a pressure threshold, the first stage trigger mode is activated and the wire embedding device is locked in the positioning position.

[0059] It is understandable that after each thread embedding, the inside of the puncture needle tube can be sprayed with medical alcohol mist for cleaning to ensure the sterility of the next operation. The above settings are routine settings and will not be described in detail.

[0060] Specifically, after the doctor locks the positioning position, the tip of the puncture needle protrudes from the cavity of the gun barrel by a preset length and touches the surface of the skin.

[0061] Specifically, the data analysis module determines the puncture mode of the thread embedding device according to the comparison result of the skin condition characterization parameter of the skin condition data and the preset skin condition characterization parameter;

[0062] If the skin condition characterizing parameter is less than or equal to the preset skin condition characterizing parameter, determining that the puncture mode of the thread embedding device is a light puncture mode;

[0063] If the skin condition characterization parameter is greater than the preset skin condition characterization parameter, the puncture mode of the thread embedding device is determined to be the intensity puncture mode.

[0064] In the embodiment of the present invention, the preset skin condition characterization parameter value is 0.7, but the above value is not limited thereto, and those skilled in the art may also adjust the value according to actual needs.

[0065] In the embodiment of the present invention, the mild puncture mode is to rotate the knob to a scale of 1-2; the strong puncture mode is to rotate the knob to a scale of 3-5.

[0066] During the implementation process, the skin state characterization parameter is the ratio of the maximum pressure value when the puncture needle contacts the skin to the maximum pressure threshold multiplied by the ratio of the maximum pressure time to the maximum pressure time threshold. The maximum pressure threshold is set to 15N, and the maximum pressure time threshold is set to 10s.

[0067] Specifically, under the condition of determining the puncture mode of the thread embedding device, the striker hits the puncture needle, and hits the puncture needle to the thread embedding position determined by the corresponding thread embedding puncture mode. The thread embedding position is determined by the scale of the rotary knob in the corresponding thread embedding puncture mode. For example, if the depth of the thread embedding position is determined to be 3 cm, the scale of the rotary knob is adjusted to 3.

[0068] Specifically, the data analysis module determines whether the puncture needle has position deviation by comparing the resistance change rate of the resistance data received by the striker in the process of the striker striking the puncture needle into the human body in the corresponding thread embedding puncture mode with the preset resistance change rate;

[0069] If the resistance change rate is less than or equal to the first preset resistance change rate, it is determined that the puncture needle has a position deviation and the puncture depth of the puncture needle is insufficient;

[0070] If the resistance change rate is greater than the first preset resistance change rate and less than or equal to the second preset resistance change rate, it is determined that no position deviation occurs;

[0071] If the resistance change rate is greater than a second preset resistance change rate, it is determined that the puncture needle has a position deviation and the puncture needle has penetrated too deep.

[0072] In an embodiment of the present invention, the preset resistance change rate includes a first preset resistance change rate and a second preset resistance change rate. The first preset resistance change rate is 0.38, and the second preset resistance change rate is 0.59. However, the above values are not limited to this, and those skilled in the art can also adjust the values according to actual needs.

[0073] During implementation, the resistance change rate is the ratio of the maximum resistance value minus the minimum resistance value of the resistance data to the average resistance value.

[0074] Specifically, the present invention determines the puncture mode through parameters characterizing the skin condition, and the striker strikes the puncture needle to the corresponding position according to the mode. The thread embedding depth is determined by rotating the knob scale. During the pushing process of the striker, the resistance change rate is analyzed and compared with the preset resistance change rate to determine whether the puncture needle deviates. The puncture mode is automatically selected according to the skin condition to avoid human judgment errors, improve the precise adaptability of the acupoint stimulation intensity, effectively reduce the risk of puncturing too deep or too shallow, and improve the accuracy of thread embedding positioning.

[0075] Specifically, the adjustment module determines to adjust the puncture depth of the puncture needle according to a comparison result of the ratio of the resistance change rate to the first preset resistance change rate and the preset ratio, under the condition that it is determined that the puncture needle has a position deviation and the puncture depth of the puncture needle is insufficient;

[0076] If the ratio is less than or equal to the preset ratio, it is determined to increase the striker extension length to a corresponding value by a preset length increase coefficient of 1.06;

[0077] If the ratio is greater than the preset ratio, determining to increase the scale of the rotary knob to a corresponding value by a preset scale increase coefficient of 1.5;

[0078] The ratio is the ratio of the resistance change rate to the first preset resistance change rate.

[0079] In the embodiment of the present invention, the preset difference value is 0.1, but the above value is not limited thereto, and those skilled in the art may also adjust the value according to actual needs.

[0080] In an embodiment of the present invention, the increased extension length of the firing pin is the product of the extension length of the firing pin and a preset length increase coefficient, and the product of the preset length increase coefficient is 1.06; the scale of the increased rotating knob is the product of the scale and a preset scale increase coefficient, and the preset scale increase coefficient is 1.5. It can be understood that the scale of the rotating knob is an integer and does not exceed 5. The increased rotating knob is rounded to the nearest integer. In order to ensure that the adjusted extension length of the firing pin and the scale of the rotating knob meet actual needs, the adjustment amplitude should not be too large, so the corresponding adjustment coefficient is set to control the adjustment amplitude.

[0081] Specifically, the adjustment module determines to adjust the puncture depth of the puncture needle according to the comparison result of the difference between the resistance change rate and the second preset resistance change rate and the preset difference, under the condition that it is determined that the puncture needle has a position deviation and the puncture depth of the puncture needle is too deep;

[0082] If the difference is less than or equal to the preset difference, it is determined to reduce the striker extension length to a corresponding value using a preset length reduction coefficient of 0.94;

[0083] If the difference is greater than the preset difference, determining to increase the scale of the rotary knob to a corresponding value by a preset scale reduction factor of 0.8;

[0084] The difference is the difference between the resistance change rate and the second preset resistance change rate.

[0085] In the embodiment of the present invention, the preset difference value is 0.3, but the above value is not limited thereto, and those skilled in the art may also adjust the value according to actual needs.

[0086] In an embodiment of the present invention, the reduced extension length of the firing pin is the product of the extension length of the firing pin and a preset length reduction coefficient, and the product of the preset length reduction coefficient is 0.94; the scale of the rotating knob after reduction is the product of the scale and a preset scale reduction coefficient, and the preset scale increase coefficient is 0.8. It can be understood that the scale of the rotating knob is an integer and not less than 1, and the reduced rotating knob is rounded off. In order to ensure that the adjusted extension length of the firing pin and the scale of the rotating knob meet actual needs, the adjustment amplitude should not be too large, so the corresponding adjustment coefficient is set to control the adjustment amplitude.

[0087] Specifically, under the condition that the puncture needle has no position deviation and reaches the predetermined position depth, the flat-head needle gently pushes the absorbable surgical suture to a preset length.

[0088] Specifically, the present invention adjusts the puncture depth by the ratio of the resistance change rate to the first preset resistance change rate. When the puncture needle depth is too deep, the adjustment module adjusts according to the difference between the resistance change rate and the second preset resistance change rate, and automatically adjusts the depth according to the actual puncture situation to ensure that the absorbable surgical suture is accurately placed in the acupuncture point, enhances the adaptability of the thread embedding device, improves the thread embedding positioning efficiency, and thus improves the thread embedding positioning accuracy.

[0089] See also Figure 3 As shown, it is a flow chart of determining whether the absorbable surgical suture pre-placement process is qualified according to an embodiment of the present invention;

[0090] Specifically, the suture analysis module determines whether the absorbable surgical suture pre-placement process is qualified based on a comparison result of the suture body slippage index of the resistance data of the flat-headed thimble gently pushing the absorbable surgical suture for the preset length and the preset suture body slippage index under the condition that the flat-headed thimble gently pushes the absorbable surgical suture for the preset length;

[0091] If the suture slip index is less than or equal to the preset suture slip index, it is determined that the absorbable surgical suture pre-placement process is qualified;

[0092] If the suture slippage index is greater than the preset suture slippage index, it is determined that the absorbable surgical suture pre-placement process is unqualified.

[0093] In the embodiment of the present invention, the preset value of the line slip index is 0.72, but the above value is not limited thereto, and those skilled in the art can also adjust the value according to actual needs.

[0094] During implementation, the suture slip index is the ratio of the average resistance when pushing the absorbable surgical suture to the average resistance threshold multiplied by the ratio of the resistance fluctuation value during the pushing process to the resistance fluctuation threshold, where the resistance fluctuation value is the difference between the maximum resistance and the minimum resistance, the average resistance threshold is set to 10N, and the resistance fluctuation threshold is set to 6N.

[0095] See also Figure 4 As shown in FIG, it is a flow chart of determining whether there is a body fluid that hinders the pre-placement process of the absorbable surgical suture according to an embodiment of the present invention.

[0096] Specifically, the suture analysis module determines whether there is any body fluid that hinders the absorbable surgical suture pre-placement process based on a comparison result of the body fluid resistance oscillation coefficient during the absorbable surgical suture pre-placement process and a preset body fluid resistance oscillation coefficient, under the condition that the absorbable surgical suture pre-placement process is determined to be unqualified;

[0097] If the body fluid resistance oscillation coefficient is less than or equal to the preset body fluid resistance oscillation coefficient, it is determined that there is no body fluid that hinders the pre-placement process of the absorbable surgical suture;

[0098] If the body fluid resistance oscillation coefficient is greater than the preset body fluid resistance oscillation coefficient, it is determined that there is body fluid that hinders the pre-placement process of the absorbable surgical suture.

[0099] In the embodiment of the present invention, the preset value of the body fluid resistance oscillation coefficient is 0.81, but the above value is not limited thereto, and those skilled in the art can also adjust the value according to actual needs.

[0100] During implementation, the fluid resistance oscillation coefficient is the ratio of the difference between the maximum resistance fluctuation amplitude and the minimum resistance fluctuation amplitude divided by the average resistance fluctuation amplitude.

[0101] Specifically, the thrust compensation module determines to increase the extension length of the flat-head needle according to a comparison result of the relative difference between the body fluid resistance oscillation coefficient and the preset body fluid resistance oscillation coefficient and the preset relative difference, under the condition that it is determined that the presence of body fluid hinders the pre-placement process of the absorbable surgical suture;

[0102] If the relative difference is less than or equal to the preset relative difference, it is determined to increase the flat head ejector extension length to a corresponding value using a first preset flat head ejector adjustment coefficient of 1.04;

[0103] If the relative difference is greater than the preset relative difference, it is determined to increase the flat head ejector pin extension length to a corresponding value using a second preset flat head ejector pin adjustment coefficient of 1.07;

[0104] The relative difference is the relative difference between the body fluid resistance oscillation coefficient and the preset body fluid resistance oscillation coefficient.

[0105] In the embodiment of the present invention, the preset relative difference value is 0.35, but the above value is not limited thereto, and those skilled in the art may also adjust the value according to actual needs.

[0106] In an embodiment of the present invention, the increased protruding length of the flat-headed thimble is the product of the protruding length of the flat-headed thimble and the preset flat-headed thimble adjustment coefficient. The preset flat-headed thimble adjustment coefficient includes a first preset flat-headed thimble adjustment coefficient, which has a value of 1.04 and a second preset flat-headed thimble adjustment coefficient, which has a value of 1.07. In order to ensure that the adjusted protruding length of the flat-headed thimble meets actual needs, the adjustment range should not be too large, so the corresponding adjustment coefficient is set to control the adjustment range.

[0107] Specifically, under the condition that it is determined that there is no body fluid that hinders the pre-placement process of the absorbable surgical suture and the pre-placement process of the absorbable surgical suture is unqualified, the knob is rotated to gear 0, the puncture needle is withdrawn, and the puncture is repositioned.

[0108] Specifically, the flat-headed thimble completely inserts the absorbable surgical suture into the human body under the condition that the pre-insertion process of the absorbable surgical suture is qualified. At this time, the flat-headed thimble is fixed. After the knob is rotated to retract the puncture needle into the thread embedding gun body, the flat-headed thimble is retracted, and the guide clamp takes out a wire tube and transports it along the guide rail to be parallel to the puncture needle. The wire clamp puts the absorbable surgical suture into the inner cavity of the puncture needle. At this time, the guide clamp sends the wire tube without absorbable surgical suture back to the single wire tube warehouse along the guide rail.

[0109] Specifically, the present invention determines whether the pre-insertion process of the absorbable surgical suture is qualified through the thread slip index, and determines whether there is fluid obstruction when it is unqualified. In the case of obstruction, the thrust compensation module adjusts the extension length of the flat-head needle according to the relative difference, thereby improving the accuracy and stability of the absorbable surgical suture placement into the acupuncture points, and improving the accuracy of the treatment effect. The thread slip index and the fluid resistance oscillation coefficient are monitored in real time, and abnormal conditions in the absorbable surgical suture placement process are discovered in time, ensuring that the absorbable surgical suture can be smoothly placed into the acupuncture points, thereby improving the accuracy of thread positioning.
