Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic therapy, in particular to a sealed laser, an ultrasonic probe fixture and a laser locator. Background Art

[0002] Focused ultrasound therapy is a new type of tumor treatment technology. This technology uses the characteristics of ultrasound that can penetrate human tissue and focus inside human tissue to generate multiple ultrasound beams outside the body, and then focus the ultrasound beams on the human lesions. Under the physical effect of ultrasound, the temperature of the lesion cells rises rapidly, achieving irreversible coagulation and necrosis. Since ultrasound energy attenuates greatly in the air, degassed water is generally used as a medium when the focused ultrasound treatment equipment is working, so that the ultrasound will not encounter air and attenuate before propagating into the human body, ensuring the therapeutic energy of the focused ultrasound.

[0003] Ultrasound is used to treat the lesion area under the guidance of ultrasound images, and lasers can be used to quickly locate the lesion area. The lasers are located on both sides of the ultrasound probe and are in the same plane as the ultrasound probe. They are located underwater during treatment, so the waterproof capability of the lasers is required to be high.

[0004] Most existing lasers are not waterproof, and some of the waterproof lasers are too large to be installed inside an ultrasonic transducer with limited space.

[0005] In the prior art, a method of waterproofing the laser is proposed. This method only uses a rubber ring to seal the laser, which has poor sealing safety. Once water penetrates into the laser, it will cause equipment failure and affect the treatment effect. Therefore, it is urgent to propose a sealed laser to solve the above problem.

[0044] Ultrasound is used to treat the lesion area under the guidance of ultrasound images. Lasers are used to quickly locate the lesion area. The lasers are located on both sides of the ultrasound probe and are in the same plane as the ultrasound probe. They are located underwater during treatment. To ensure the safety of treatment, the waterproof performance of the laser is crucial. Most existing lasers are not waterproof or have poor waterproof capabilities. Once water penetrates into the laser, it will cause equipment failure and affect the treatment effect.

[0045] The utility model provides a sealed laser, an ultrasonic probe fixture and a laser locator, which can solve the problems existing in the prior art that the laser has no waterproof capability and has poor sealing safety.

[0046] In a first aspect, the utility model provides a sealed laser, see Figure 1 , including: a laser tube 10, a transparent end cover 11, and a sealing tube 12;

[0047] The transparent end cap 11 is a stepped structure; the sealing tube 12 is a through tube and the length of the sealing tube 12 is greater than the length of the laser tube 10;

[0048] As a possible implementation method, the transparent end cap is an organic glass end cap, and the sealing tube is an organic glass tube. Organic glass has good transparency, chemical stability, mechanical properties and weather resistance, can ensure that the laser emitted by the laser tube is normally emitted from the transparent end cap, adapts to the underwater environment and has high stability and safety.

[0049] See also Figure 1 The transparent end cap 11 is buckled on one end of the sealing tube 12, and the outer wall diameter of the end face of the sealing tube 12 is the same as the diameter of the closed end face of the transparent end cap 11; the outer wall of the small diameter part of the transparent end cap 11 and the part in contact with the inner wall of the sealing tube 12 are bonded by light-curing epoxy resin to form a barrel-shaped cavity capable of accommodating the laser tube;

[0050] The transparent end cap is tightly fastened to the sealing tube, which can not only ensure that the outer wall of the sealing tube is evenly stressed but also play a certain waterproof role. Before fastening, light-curing epoxy resin is applied to the outer wall of the small diameter part of the transparent end cap, which has a good sealing effect after fastening without affecting the projection of the laser.

[0052] There is a gap between the laser tube and the inner wall of the barrel-shaped cavity, and the length of the laser tube is smaller than the length of the sealing tube. The laser tube is placed in the barrel-shaped cavity to ensure that the laser emission end face of the laser tube is coaxially well fitted with the bottom surface of the barrel-shaped cavity. Use a syringe to inject epoxy resin into the gap between the laser tube and the inner wall of the barrel-shaped cavity along the inner wall of the sealing tube until the sealing tube is filled. Let it stand until the epoxy resin is completely cured. At this time, the laser tube is sealed and fixed in the barrel-shaped cavity.

[0053] As a possible implementation, the outer surface of the circuit board of the laser tube is coated with a conformal coating layer.

[0054] The three-conformal paint has good moisture-proof, radiation-proof and leakage-proof effects. Applying the three-conformal paint layer can protect the circuit board and further improve the waterproof ability of the sealed laser.

[0055] As an example, the process of making a sealed laser includes the following steps:

[0056] S10. Spraying three-conformal paint layer;

[0057] Wrap the metal head of the laser tube with masking paper, wrap the wire of the laser tube with a thermoplastic tube, and spray the circuit board of the laser tube with three-proof paint in two times, with an interval of more than 4 hours between the two sprayings.

[0058] S11. Connect the transparent end cap and the sealing tube;

[0059] Use tweezers to apply light-curing epoxy resin with a thickness of about 0.5 mm on the outer wall of the small-diameter end of the transparent end cap, and buckle the transparent end cap with one end of the sealing tube to obtain a barrel-shaped cavity.

[0060] S12. Sealed laser tube;

[0061] Remove the masking paper and heat sink tube on the laser tube, insert the laser tube into the barrel-shaped cavity, and make the emitting end face of the laser tube coaxially and tightly fit with the bottom face of the barrel-shaped cavity; use a syringe to inject epoxy resin into the gap between the laser tube and the inner wall of the barrel-shaped cavity along the inner wall of the sealing tube until the sealing tube is filled; use a light curing machine to cure the epoxy resin until it is in a solid state to obtain a sealed laser.

[0062] In a second aspect, the utility model provides an ultrasonic probe clamp, see Figures 2 to 3 The ultrasonic probe fixture is provided with N mounting holes 20 for mounting and fixing the sealed laser 1 provided by the first aspect of the utility model.

[0064] As a possible implementation, the protrusion is an annular protrusion or a tooth-shaped protrusion. The function of the protrusion is to support the sealing ring sleeved on the outer wall of the sealed laser. Therefore, the shape of the protrusion is not specifically limited, and both an annular shape and a tooth-shaped shape can achieve the purpose of the utility model.

[0065] See also Figure 3 As a possible implementation method, a thread 22 is provided on the inner wall of the mounting hole from the protrusion to the hole end.

[0067] See also Figure 4 As an example, the sealing ring 3 is a rubber ring with a certain elasticity, which is pressed tightly against the outer wall of the sealing tube under the action of tension and is not easy to slide.

[0068] As a possible implementation method, the nut is a stainless steel nut, and the nut is screwed into the mounting hole. The nut has an external thread structure, and the nut is screwed into the mounting hole until the sealing ring is compressed, which effectively prevents moisture from penetrating through the mounting hole and damaging the ultrasonic probe, and at the same time plays a good fixing role.

[0069] As a possible implementation, the laser locator further includes a protective cover, which is detachably connected to the end face of the ultrasonic probe fixture, and the protective cover is provided with a through hole corresponding to the mounting hole and having the same size.
