[0034] like Figures 1 to 6 The linear scanning ultrasonic probe shown includes: a shell 10 and a probe 20, a temperature control component 30 and a transmission component 40 arranged inside the shell 10;

[0035] A conductive window 10a is provided at one end of the housing 10, a diaphragm 10b is sealed at the conductive window 10a, and the probe 20 is arranged toward one side of the conductive window 10a;

[0036] The temperature control assembly 30 includes a pair of temperature sensors 31, the two temperature sensors 31 are respectively arranged on both sides of the conduction window 10a, and the probe 20 is located between the two temperature sensors 31;

[0037] The transmission component 40 includes a first transmission part 41 and a second transmission part 42. The first transmission part 41 and the second transmission part 42 are arranged parallel to each other, and the first transmission part 41 is located between the probe 20 and the second transmission part 42.

[0038] The first transmission part 41 includes a transmission rod 41a and a transmission block 41b. The transmission block 41b is sleeved on the transmission rod 41a and is slidably connected to the transmission rod 41a. The transmission block 41b extends on both sides and is respectively connected to the probe 20 and the second transmission part 42. The second transmission part 42 is connected to the driving mechanism outside the shell 10.

[0039] The utility model sets temperature sensors 31 on both sides of the conduction window 10a of the shell 10, so that the temperature sensor 31 can detect the temperature of the skin position where the ultrasound probe is located in real time. At the same time, under the driving and guiding action of the first transmission part 41 and the second transmission part 42, the probe 20 can slide stably along the length direction of the transmission rod 41a, ensuring the accuracy of the position of the probe 20, thereby effectively ensuring the safety of the use process.

[0040] The driving mechanism is connected to the second transmission part 42, driving the relative position of the second transmission part 42 and the shell 10 to change. Under the connecting action of the transmission block 41b, the positions of the transmission block 41b and the probe 20 are synchronously and stably moved, thereby changing the action position of the ultrasonic wave emitted by the probe 20. During the whole process of use, the current skin temperature is sensed in real time through the temperature sensor 31, thereby ensuring the safety of use.

[0041] On the basis of the above embodiment, both ends of the transmission rod 41a are fixedly arranged inside the shell 10, and the outer cross-section of the transmission rod 41a is a polygonal structure; the transmission block 41b is prevented from rotating relative to the transmission rod 41a during the movement of the transmission block 41b along the transmission rod 41a, thereby avoiding the deflection of the probe 20 and ensuring the accuracy of the position during the movement.

[0042] On the basis of the above embodiment, the second transmission part 42 includes a driving rod 42a, a connecting block 42b, an elastic tube 42c and a sleeve rod 42d; the driving rod 42a and the sleeve rod 42d are coaxially arranged, one end of the sleeve rod 42d is fixedly connected to the inside of the shell 10, and the other end extends into the end surface of one end of the driving rod 42a, and the other end of the driving rod 42a away from the sleeve rod 42d extends out of the shell 10; the connecting block 42b is fixed to the outer wall of the driving rod 42a close to the sleeve rod 42d, the transmission block 41b is fixedly connected to the connecting block 42b, and the elastic tube 42c is sleeved on the sleeve rod 42d, and the two ends are respectively connected to the end of the sleeve rod 42d and the end of the connecting block 42b.

[0043] The driving mechanism causes the driving rod 42a to move relative to each other, thereby driving the connecting block 42b fixed on the driving rod 42a to move relative to each other. At the same time, the relative position of the sleeve rod 42d extending into the driving rod 42a changes, causing the elastic tube 42c to stretch or compress. The change in position of the connecting block 42b drives the transmission block 41b to slide along the transmission rod 41a, thereby driving the relative position of the probe 20 in the shell 10 to change, thereby accurately changing the action position of the ultrasonic wave emitted by the probe 20.

[0044] On the basis of the above embodiment, an electromagnetic head 42e is provided at the end of the driving rod 42a extending outside the shell 10, and the driving rod 42a is electromagnetically connected to the external driving mechanism through the electromagnetic head 42e; by changing the size and direction of the magnetic field acting on the electromagnetic head 42e, the size and direction of the force acting on the driving rod 42a are changed, thereby changing the speed and direction of the movement of the driving rod 42a.

[0045] On the basis of the above embodiment, a sensing head 42f is arranged on the top of the connecting block 42b, and the sensing head 42f is arranged toward the side away from the conductive window 10a; by arranging a sensing device outside the shell 10 to receive the signal emitted by the sensing head 42f, the current position of the connecting block 42b is determined, and then the position information of the probe 20 is determined, thereby realizing real-time monitoring of the position of the probe 20.

[0046] On the basis of the above embodiment, the shell 10 includes a first division 11 and a second division 12, and the first division 11 and the second division 12 are correspondingly provided with connecting columns 13 and connecting holes 14, and the connecting columns 13 and the connecting holes 14 are snap-connected; by setting the shell 10 as the first division 11 and the second division 12, it is convenient to assemble the probe 20, the temperature control component 30 and the transmission component 40 inside the shell 10. After the assembly is completed, the first division 11 and the second division 12 can be combined again to form a complete box structure through the snap-connection between the connecting column 13 and the connecting hole 14, which is simple and convenient.

[0047] On the basis of the above embodiment, two clamping plates 32 are provided in the first section 11 corresponding to the temperature sensor 31, the clamping plate 32 is Z-shaped, and the temperature sensor 31 is fixed between the clamping plate 32 and the inner wall of the shell 10; the position of the temperature sensor 31 is quickly limited and determined by the two Z-shaped clamping plates 32 to prevent the temperature sensor 31 from shifting in the shell 10, thereby ensuring the accuracy of temperature monitoring.

[0048] On the basis of the above embodiment, the shell 10 is filled with a conductive medium, and a sealing groove 15 is provided at the edge of the shell 10, and the sealing groove 15 is filled with sealant; ultrasonic waves can enter the skin tissue through the diaphragm 10b at the conductive window 10a through the transmission effect of the conductive medium, thereby ensuring the smooth conduction of ultrasonic waves. At the same time, sealant is provided at the edge of the shell 10 to fill the sealing groove 15 to prevent leakage after the first section 11 and the second section 12 are assembled.

[0049] On the basis of the above embodiment, a wiring hole 16 and a threading hole 17 are provided on the side of the first section 11 away from the conduction window 10a, and the line 18 passes through the wiring hole 16, is attached to the inner wall of the first section 11, and is connected to the two temperature sensors 31; the connecting line of the probe 20 extends from the side of the probe 20 away from the conduction window 10a, is transitionally connected to the transmission block 41b, and is led out of the shell 10 from the threading hole 17. By setting the wiring hole 16 and the threading hole 17, the connecting line and the line 18 can be led out of the shell 10 to realize the control of the temperature sensor 31 and the probe 20.

[0050] On the basis of the above embodiment, a wire blocking block 19 is fixedly connected in the first division 11. The wire blocking block 19 is in the shape of a long strip and is located between the first transmission part 41 and the second transmission part 42, and forms a gap with the inner wall of the first division 11; the connecting wire of the probe 20 is confined in the gap to prevent the connecting block 42b from driving the probe 20 and the connecting wire of the probe 20 to move back and forth, and the connecting wire from interfering with the elastic tube 42c during the shaking of the shell 10 as a whole, thereby affecting the normal operation of the probe 20 and ensuring the accuracy of the position movement.
