[0043] Please refer to Figures 1 to 5 and Figure 8 and Fig. 9 The present invention provides a laser guide 100 for ultrasonic puncture, comprising:

[0044] The housing 1 has a laser emitting port 11 at its front end. The housing 1 of the present invention is made of plastic.

[0045] The fixing card 2 is arranged on the bottom surface of the housing 1, and the fixing card 2 is used to fix the housing 1 on the ultrasonic probe 200. The axial direction of the laser emission port 11 is arranged at an angle with the axial direction of the fixing card 2, such as Figure 3 As shown, the angle is θ. Figure 8 and Fig. 9 As shown, after the shell 1 is fixed on the ultrasonic probe 200, the entire guide 100 is fixed on the ultrasonic probe 200. At the same time, since the axial direction of the laser emitting port 11 is set at an angle with the axial direction of the fixing card 2, the axial direction of the laser emitting port 11 and the axial direction of the ultrasonic probe 200 are also set at an angle θ.

[0046] The fixing card 2 of the present invention is an elastic structure, which can firmly clamp the fixing card 2 on the ultrasonic probe 200. Preferably, the fixing card 2 of the present invention is an elastic C-shaped fixing card, which has a notch so that it can be easily and quickly clamped and fastened on the ultrasonic probe 200.

[0047] The laser module 3 is disposed in the housing 1 and is used to generate laser light and emit it from the laser emission port 11 ; preferably, the laser module 3 of the present invention generates red laser light.

[0048] The battery 4 is electrically connected to the laser module 3 and is used to supply power to the laser module 3 .

[0049] The control switch 5 is exposed on the surface of the housing 1 , is electrically connected to the battery 4 , and is used to control the on and off of the power supply of the laser module 3 .

[0050] Puncture guidance and positioning principle: When the laser guide 100 of the present invention is fixed to the front end of the ultrasonic probe 200 through the fixing card 2, the ultrasonic probe 200 detects and searches for the target object to be punctured (such as diseased tissue) in the abdominal cavity. After the ultrasonic probe 200 detects and finds the target object to be punctured, the position of its front end in the abdominal cavity is fixed. At this time, the laser emitted by the laser module 3 of the laser guide 100 is emitted to the inner wall of the abdominal cavity at an angle of θ with the axial direction of the ultrasonic probe 200. Then the laser passes through the inner wall of the abdominal cavity to form a halo (red, blue, etc.) on the outer wall of the abdominal cavity. The doctor punctures the outer wall of the abdominal cavity in the middle position of this halo and can accurately reach the required position. In this way, the laser guide of the present invention can quickly and accurately perform puncture positioning, avoiding repeated trial and error and damaging other tissues.

[0051] Specifically, Figures 4 to 5 As shown, the laser module 3 of the present invention includes a laser head 31 , a laser generating circuit board 32 connected to the laser head 31 , and a first electrode sheet 33 and a second electrode sheet 34 .

[0052] One end of the first electrode sheet 33 is electrically connected to the laser generating circuit board 32 , and the other end is connected to the first electrode 41 of the battery 4 .

[0053] One end of the second electrode sheet 34 is electrically connected to the laser generating circuit board 32 , and the other end thereof is in contact with the control switch 5 or the second electrode 42 of the battery 4 .

[0054] The electric energy of the battery 4 is transmitted to the laser generating circuit board 32 through the first electrode sheet 33 and the second electrode sheet 34. The laser generating circuit board 32 converts the electric energy into light energy, and then emits the corresponding laser through the laser head 31. In this embodiment, the first electrode 41 of the battery 4 is a negative electrode, and the corresponding first electrode sheet 33 connected thereto is a negative electrode sheet, and the second electrode 42 of the battery 4 is a positive electrode, and the corresponding second electrode sheet 34 connected thereto is a positive electrode sheet.

[0055] When the second electrode sheet 34 abuts against the second electrode 42 of the battery 4, the power supply of the laser generating circuit board 32 is in the on state, and laser is generated. When the second electrode sheet 34 abuts against the control switch 5, it is disconnected from the second electrode 42 of the battery 4, the power supply of the laser generating circuit board 32 is in the off state, and no laser is generated.

[0056] Preferably, the fixing card 2 of the present invention fixes the housing 1 of the laser guide 100 beside the ultrasonic detection surface 201 at the front end of the ultrasonic probe 200 and is located behind the ultrasonic detection surface 201. The laser guide 100 is fixed behind the ultrasonic detection surface 201 of the ultrasonic probe 200 and is arranged adjacent to the ultrasonic detection surface 201, so that after the ultrasonic detection surface 201 detects the target object to be punctured, the starting point of the laser emitted by the laser guide 100 is also basically located at the position of the target object to be punctured. When the doctor performs puncture through the halo of the outer wall of the abdominal cavity, he can accurately puncture toward the position to be punctured at the front end of the ultrasonic probe 200, thereby improving the accuracy of puncture.

[0057] Furthermore, the laser emission port 11 of the shell 1 of the present invention faces away from the front end of the ultrasonic probe 200, and the axial direction of the laser emission port 11 is set at an angle of 20 to 90 degrees with the axial direction of the fixing card 2, that is, the angle θ is 20 to 90 degrees. In this way, after the ultrasonic probe 200 performs detection and positioning in the front, the laser is emitted at an angle θ to the inner wall of the abdominal cavity backward and upward, and then forms a halo on the outer wall of the abdominal cavity at the rear and upper position of the ultrasonic probe 200, which is convenient for doctors to perform puncture operations from back to front. Preferably, the axial angle θ between the laser emission port 11 and the axial angle of the fixing card 2 is 60 degrees, at which time the puncture angle is optimal.

[0058] Please continue to refer to Figures 4 to 6 The housing 1 of the present invention includes an upper shell 12 and a lower shell 13 which enclose a receiving cavity 14. The receiving cavity 14 sequentially receives the laser module 3, the battery 4 and the control switch 5 from front to back.

[0059] The front ends of the upper shell 12 and the lower shell 13 are open together to form the laser emission port 11, the bottom surface of the lower shell 13 is integrally formed with the fixing card 2, and the rear ends of the upper shell 12 and the lower shell 13 are open together to form a sliding slot 15 for exposing the control switch 5. The upper shell 12 and the lower shell 13 are separately arranged to facilitate the installation of the laser module 3, and the lower shell 13 and the fixing card 2 are arranged as an integral structure to facilitate the quick fixing of the housing 1 on the ultrasound probe 200.

[0060] Preferably, the bottom edge of the upper shell 12 of the present invention is sunken to form a snap-fit ​​groove 121, and the top edge of the lower shell 13 is convex to form a snap-fit ​​protrusion 131, and the snap-fit ​​protrusion 131 is snap-fitted with the snap-fit ​​groove 121. The snap-fit ​​protrusion 131 and the snap-fit ​​groove 121 realize the quick snap-fitting of the upper shell 12 and the lower shell 13.

[0061] Furthermore, the bottom edge of the upper shell 12 of the present invention is also provided with a plurality of engaging columns 122, and the top edge of the lower shell 13 is also provided with a plurality of engaging holes 132, and the engaging columns 122 are inserted into the engaging holes 132. The interference fit between the engaging columns 122 and the engaging holes 132 strengthens the firmness of the connection between the upper shell 12 and the lower shell 13.

[0062] like Figure 7 As shown, preferably, the control switch 5 of the present invention comprises a plate portion 51 and a handle portion 52 protruding from a surface of the plate portion 51, the handle portion 52 is slidably disposed and exposed in the sliding groove 15, and a sliding inclined surface 511 is disposed on one side of the plate portion 51 adjacent to the second electrode sheet 34 to contact or disengage with the second electrode sheet 34. Figure 7 As shown in , when the handle 52 of the control switch 5 is pushed upward, the plate 51 moves upward with it, driving the sliding slope 511 upward, and the second electrode sheet 34 gradually disengages from the sliding slope 511, and then contacts with the second electrode 42 of the battery 4 to conduct the power supply circuit of the battery 4; when the handle 52 of the control switch 5 is pushed downward, the plate 51 moves downward with it, driving the sliding slope 511 downward, and the sliding slope 511 gradually inserts between the second electrode sheet 34 and the battery 4, so that the second electrode sheet 34 is disengaged from the battery 4 and the power supply circuit of the battery 4 is disconnected. The setting of the sliding slope 511 makes the control switch 5 of the present invention simple in structure and convenient in sliding operation.

[0063] like Figure 8 and Fig. 9 As shown, the present invention further proposes a guiding device 400, comprising the above-mentioned laser guide 100 for ultrasonic puncture, and also comprising a puncture device 300, an ultrasonic probe 200 and a host (not shown) electrically connected to the ultrasonic probe, the ultrasonic probe 200 is sleeved in the puncture device 300, the ultrasonic probe 200 comprises a rod 202 and an ultrasonic detection surface 201 arranged at the front end of the rod, the fixing card 2 of the laser guide 100 is engaged and fixed to the rod 202 of the ultrasonic probe 200, and the laser guide 100 is located behind the ultrasonic detection surface 201 and is arranged adjacent to the ultrasonic detection surface 201.

[0064] The laser emitting port 11 of the laser guide 200 faces away from the front end of the ultrasonic probe 200, and the axial direction of the laser emitting port 11 forms an angle of 20 to 90 degrees with the axial direction of the ultrasonic probe 200. Fig. 9 The angle θ in is 20 to 90 degrees.

[0065] When in use, the puncture device 300 is first inserted into the abdominal cavity, and then the ultrasonic probe 200 equipped with the laser guide 100 is inserted into the puncture device 300 and enters the abdominal cavity. Then, the ultrasonic probe 200 is used to detect the target object to be punctured in the abdominal cavity. At the same time, the laser guide 100 generates laser to form a halo on the outer wall of the abdominal cavity. The doctor determines the position of the ultrasonic detection surface 201 at the front end of the intra-abdominal ultrasonic probe 200 according to the position of the halo, that is, the position of the target object to be punctured, so as to facilitate the subsequent rapid and accurate puncture from the halo to the position of the target object to be punctured on the ultrasonic detection surface 201 of the ultrasonic probe 200.

[0066] Furthermore, the axial direction of the laser emitting port 11 of the laser guide 100 of the present invention forms an angle of 60 degrees with the axial direction of the ultrasonic probe 200. At this time, the operating angle is optimal.

[0067] The laser guide 100 and the guide device 400 for ultrasonic puncture proposed in the embodiment of the present invention are provided with a shell 1, and a fixing card 2 is provided on the bottom surface of the shell 1 to fix the shell 1 on the ultrasonic probe 200. At the same time, a laser module 3 is provided in the shell 1. The laser module 3 generates laser light and emits it from the laser emission port 11 at the front end of the shell 1. The axial direction of the laser emission port 11 is set at an angle with the axial direction of the fixing card 2. In this way, when the ultrasonic probe 200 is positioned in the abdominal cavity, the laser light generated by the guide 100 on the ultrasonic probe 200 is inclined with the axial direction of the ultrasonic probe 200 and is emitted to the inner wall of the abdominal cavity and penetrates the inner wall of the abdominal cavity. The laser light penetrating the inner wall of the abdominal cavity forms a halo on the outer wall of the abdominal cavity. The doctor can accurately reach the required position by puncturing the outer wall of the abdominal cavity with the middle position of the halo. The laser guide 100 of the present invention can quickly and accurately perform ultrasonic puncture positioning in the abdominal cavity, improve work efficiency, and avoid repeated trial and error to damage other tissues.
