[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0038] Example 1
[0039] This embodiment provides an intracranial probe 10, such as Figure 1-Figure 5 As shown, it includes: a shell 11, a pressure chip 12, a sensing line 13, etc.
[0040] The shell 11 is provided with a window 111, and the interior of the shell 11 is provided with a accommodating chamber 112 which is connected with the window 111; the pressure chip 12 is arranged in the accommodating chamber 112, and the pressure chip 12 includes at least three pins, and two adjacent pins are arranged at intervals; the induction wire 13 includes at least three core wires, and two adjacent core wires are arranged at intervals, and the core wires correspond to the pins one by one, and the correspondingly arranged core wires and pins are suitable for welding.
[0041] Specifically, Figure 3 , Figure 4 As shown, the accommodation chamber 112 provides an installation position for the pressure chip 12. The pressure chip 12 and the sensing wire 13 form a pressure sensor through the electrical connection of corresponding pins and core wires. The pressure chip 12 faces the window 111 to achieve the purpose of positively sensing the intracranial pressure. At least three core wires are combined into one sensing wire 13 and a one-to-one corresponding wiring form is formed with at least three pins at the end of the sensing wire 13, which is convenient for welding the wire in a micro state.
[0042] This embodiment provides an intracranial probe 10, in which three pins arranged on the pressure chip 12 correspond to the three core wires of the sensing wire 13 one by one, and the pins and core wires arranged at intervals from each other make the welding points of the pins and core wires spaced apart from each other by a certain distance during the welding operation, and adopt the welding form of non-contact heat flow welding to ensure that multiple welding points are independent of each other and avoid the phenomenon of bridging tin. Thus, the defect in the prior art that when the pins of the pressure chip 12 of the intracranial probe 10 are welded to the corresponding core wires of the sensing wire 13, the welding points of the adjacent pins and core wires are prone to bridging tin, resulting in the failure of the welding between the pressure chip 12 and the core wire.
[0043] Furthermore, non-contact heat flow welding is adopted between the core wire and the pin. The specific implementation method is to clamp the pressure chip 12 by a flexible clamp, apply solder at the welding point of the pin position of the pressure chip 12, adjust the three core wires of the induction line 13 into place one by one, adjust the relevant parameters of the welding hot air gun, and realize rapid soldering by the welding hot air gun. Surface micro-welding is realized without contacting the pressure chip 12, which not only enables the solder to be formed but also protects the pressure chip 12 and its surface film, further solving the problem of bridging caused by the pressure chip 12 being too small during welding.
[0044] Furthermore, the relevant parameters of the welding hot air gun are: temperature 450°C, wind speed 2.5 gears, the distance from the pin of the pressure chip 12 during welding is 15 cm, and the position angle is 80°.
[0045] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 4 As shown, the pins include a first pin 121, a second pin 122 and a third pin 123, the core wires include a first core wire 131, a second core wire 132 and a third core wire 133, the first core wire 131 and the third core wire 133 are located on both sides of the second core wire 132 and are laterally offset respectively, the first core wire 131 is welded to the first pin 121, the second core wire 132 is welded to the second pin 122, and the third core wire 133 is welded to the third pin 123.
[0046] Specifically, when the end of the sensing wire 13 is welded to the pressure chip 12, since the core wire of the sensing wire 13 is extremely thin, the three core wires need to be made under an optical microscope to meet the welding requirements on the tiny chip. The second core wire 132 is located in the middle and is arranged in a straight line. Based on the second core wire 132, the first core wire 131 and the third core wire 133 located on both sides of the second core wire 132 are unfolded using a probe under an optical microscope, so that the first core wire 131, the second core wire 132 and the third core wire 133 are arranged at intervals from each other and correspond to the first pin 121, the second pin 122 and the third pin 123 one by one, so as to facilitate the subsequent welding operation.
[0047] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 4 As shown, the offset angle of the first core wire 131 relative to the second core wire 132 is the same as the offset angle of the third core wire 133 relative to the second core wire 132, and the first pin 121, the second pin 122 and the third pin 123 are arranged in sequence and equidistantly.
[0048] Specifically, the offset angle of the first core wire 131 relative to the second core wire 132 is set to be the same as the offset angle of the third core wire 133 relative to the second core wire 132, so that the first core wire 131, the second core wire 132 and the third core wire 133 are equidistantly arranged between adjacent ones; at the same time, the first pin 121, the second pin 122 and the third pin 123 are arranged in sequence and equidistantly arranged, so that the first core wire 131, the second core wire 132 and the third core wire 133 can accurately correspond to the first pin 121, the second pin 122 and the third pin 123 when they are respectively welded, thereby improving the accuracy of subsequent welding operations.
[0049] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 4 As shown, the diameter of the core wire ranges from 0.07mm to 0.09mm.
[0050] Specifically, the diameter range of the core wire is set to 0.07 mm to 0.09 mm, thereby ensuring that the sensing wire 13 has a sufficiently small size specification for subsequent installation.
[0051] Further, as a preferred embodiment, the diameter of the core wire is set to 0.08 mm.
[0052] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 4 As shown, the pressure chip 12 includes a circuit board 124 and a pressure sensing diaphragm 125 , and the pins are electrically connected to the circuit board 124 and / or the pressure sensing diaphragm 125 .
[0053] Specifically, the pressure chip 12 includes a circuit board 124 and a pressure sensing diaphragm 125 disposed on the circuit board 124. The circuit board 124 is configured as a plate-like structure, and the circuit board 124 is provided with a sensing port connected to the airway, and the pressure sensing diaphragm 125 is disposed at the sensing port. The front of the pressure sensing diaphragm 125 bears the intracranial pressure of the intracranial fluid, and the back of the pressure sensing diaphragm 125 bears the external atmospheric pressure. The atmospheric pressure is used as the zero point of the measured pressure, and the difference between the intracranial pressure borne by the pressure sensing diaphragm 125 and the atmospheric pressure is the intracranial pressure detected by the pressure sensor. The pins are electrically connected to the circuit board 124 and the pressure sensing diaphragm 125, and the pins are welded to the core wire of the sensing line 13 to transmit the intracranial pressure signal to the outside through the sensing line 13.
[0054] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 5 As shown, the intracranial probe 10 further includes a packaging component, which is disposed on a side of the pressure chip 12 facing the window 111 and is suitable for sealing the window 111 .
[0055] Specifically, by setting up a packaging component, the window 111 of the shell 11 is closed, and while ensuring smooth measurement, the pressure chip 12 located in the accommodation chamber 112 is prevented from directly contacting the intracranial fluid, and the circuit arranged on the surface of the pressure chip 12 is prevented from being affected by the disturbance of the intracranial fluid, thereby ensuring the reliability of the measurement data of the pressure chip 12 and the long-term working stability.
[0056] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 , Figure 5 As shown, a step structure 113 is formed on the side wall of the containing chamber 112 , the pressure chip 12 is placed on the table of the step structure 113 and faces the window 111 , and the packaging component is arranged on the side of the pressure chip 12 facing the window 111 .
[0057] Specifically, a circuit board 124 and a sensing element are provided on the pressure chip 12. The pressure chip 12 is packaged using a packaging assembly to prevent the circuit board 124 and the sensing element from directly contacting the intracranial fluid, thereby ensuring that the circuit on the surface of the pressure chip 12 is not affected by the disturbance of the intracranial fluid, thereby ensuring the reliability of the measurement data of the pressure chip 12 and the long-term working stability.
[0058] Furthermore, when the intracranial probe 10 is inserted into the skull, a portion of the intracranial fluid is located around the shell 11 of the intracranial probe 10, and the intracranial probe 10 achieves the purpose of detecting the intracranial pressure by detecting the pressure of the peripheral fluid of the intracranial probe 10. Since the shell 11 is provided with a window 111, most of the intracranial fluid around the shell 11 flows toward the direction of the accommodation chamber 112 of the shell 11 along the direction facing the window 111. In order to enable the pressure sensor to accurately detect the pressure of the intracranial fluid flowing to the window 111, a step structure 113 is provided on the side wall of the accommodation chamber 112, and the pressure chip 12 is arranged on the table of the step structure 113 so that the pressure chip 12 is arranged facing the window 111, thereby achieving the purpose of positively sensing the pressure of the intracranial fluid and improving the sensing accuracy of the pressure chip 12.
[0059] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, the pressure chip 12 includes a circuit board 124 and a pressure sensing diaphragm 125, and the packaging assembly includes: a first sensing coating and a second sensing coating
[0060] The first sensing coating covers the circuit board 124 ; the second sensing coating is distributed in a mesh shape and covers the pressure sensing diaphragm 125 .
[0061] Specifically, since the pressure chip 12 is tiny and fragile, the circuit board 124 except the working area of the pressure sensing diaphragm 125 is coated with glue to form a first sensing coating, which protects part of the circuit board 124 and prevents the circuit board 124 from directly contacting the intracranial fluid. At the same time, since the intracranial probe 10 is a disposable implant product, in order to prevent the pressure chip 12 from zero drift, a layer of pressure film is formed by reciprocating drawing on the surface of the pressure chip 12, that is, the working area of the pressure sensing diaphragm 125 is coated with a second sensing coating distributed in a silk screen shape, which protects part of the pressure sensing diaphragm 125 and prevents the pressure sensing diaphragm 125 from directly contacting the intracranial fluid.
[0062] On the basis of the above embodiment, as a further limited embodiment, the packaging component further includes packaging glue, which covers the outer sides of the first sensing coating and the second sensing coating and is suitable for sealing the window 111 .
[0063] Specifically, after coating the first sensing coating and the second sensing coating on the circuit board 124 and the pressure sensing diaphragm 125 respectively, packaging glue is further filled on the outside of the first sensing coating and the second sensing coating to fix the position of the pressure sensor while sealing the window 111 of the shell 11, further preventing the pressure sensor from directly contacting the intracranial fluid.
[0064] Furthermore, the sensing coating has the characteristics of high dielectric strength, good water vapor penetration resistance, etc., and materials such as Parylene, epoxy resin, silicone resin, etc. can be selected. The sensing coating is applied after the hot pressing process is completed, so that the sensing coating can transmit the pressure of the intracranial fluid to the pressure chip 12, thereby reducing the influence of the sensing coating on the measurement accuracy of the pressure chip 12.
[0065] Example 2
[0066] This embodiment provides an intracranial detection component 100, such as Figure 1 , Figure 2 As shown, the intracranial detection component 100 includes: the intracranial probe 10 and the catheter component provided in the embodiment.
[0067] The catheter assembly includes a drainage tube 20 and an intracranial pressure catheter 30. The intracranial probe 10 is arranged inside the drainage tube 20. The drainage tube 20 is provided with a drainage port corresponding to the window 111 of the intracranial probe 10. The sensing wire 13 is arranged inside the intracranial pressure catheter 30. The intracranial pressure catheter 30 is arranged inside the drainage tube 20 and is connected with the through hole 114 of the intracranial probe 10.
[0068] Specifically, the drainage tube 20 has a certain rigidity, which can provide good protection for the internal pressure sensor and temperature sensor, and prevent the entire intracranial probe 10 from being invalidated due to the impact and collision of external stress. The drainage tube 20 should be made of biocompatible materials, such as polymer plastics, titanium alloys, stainless steel, ceramics, etc. When implanted, the intracranial probe 10 needs to pass through the surface of the human body to reach the internal tissue. In order to prevent damage to the human tissue and increase the patient's pain, the drainage tube 20 should be made into a smooth curved surface without edges and corners. Specifically, the distal end 21 of the drainage tube 20 is set as an arc-shaped shell. A window 111 is opened in the middle of the drainage tube 20. The function of this window 111 is to allow the sensing surface of the pressure sensor to directly contact the external environment to ensure the accuracy of the measurement. The intracranial pressure catheter 30 provides an installation position for the sensing line 13.
[0069] On the basis of the above implementation manner, as a further limited implementation manner, Figure 1 , Figure 2 As shown, the intracranial probe 10 is arranged at the distal end 21 of the drainage tube 20 , the drainage port is arranged on the tube wall of the distal end 21 , and the side wall of the middle section 22 of the drainage tube 20 is also provided with a drainage hole connected to the window 111 .
[0070] Specifically, by draining the intracranial probe 10 through the drainage port and the drainage hole at the same time, the flow stability of the fluid at the intracranial probe 10 can be improved, and the phenomenon of concentrated action of the intracranial fluid on the intracranial probe 10 at the drainage port, resulting in detection distortion, can be reduced.
[0071] Furthermore, the intracranial detection component 100 also includes a drain valve 24, which is arranged at the proximal end 23 of the drainage tube 20 and is connected to the internal space of the drainage tube 20, and is used to drain the intracranial fluid in the drainage tube 20 to the outside of the human tissue, so as to achieve the purpose of regulating intracranial pressure.
[0072] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
