Ultrasonic treatment probe

Abstract

The utility model discloses an ultrasonic treatment probe which comprises a grab handle shell, a head shell installed on the grab handle shell, an energy converter arranged in the head shell, a cross rod connected to the energy converter, a rubber sheet installed on the inner wall of the head shell, and an ultrasonic transducer connected to the other end of the cross rod and extending into the grab handle shell. An inner groove located between the water inlet groove and the water outlet groove is formed in the grab handle shell, and a telescopic protection sleeve is installed in the inner groove. Through the elastic action of the rubber sheet, the rubber sheet can make close contact with the cross rod, so that the possibility that cooling water enters the grab handle shell is reduced, even if a small amount of cooling water passes through the space between the rubber sheet and the cross rod, the cooling water can enter the inner groove, and due to the fact that the section of the telescopic protective sleeve is in a wrinkle shape, multiple protection is formed, and the cooling water is further blocked; and the elastic force recovery effect of the foam enables the whole telescopic protective sleeve to contract towards the middle part, so that the telescopic protective sleeve can continuously keep a tight contact state with the cross rod, and a good waterproof effect is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to an ultrasonic treatment probe. Background Art

[0002] Prostate disease is a common disease in adult men, including prostatitis, prostatitis, etc. Due to the special anatomical location and structure of the prostate, the efficacy of traditional methods such as oral administration in treating prostate disease is limited to a certain extent.

[0003] Ultrasonic therapy mainly uses the principle of ultrasound to penetrate deep into the tissue, thereby producing corresponding therapeutic effects. The transrectal high-intensity focused ultrasound therapy device is based on the principle of ultrasound. The probe is inserted into the rectum. The transducer with imaging and ablation functions will image and locate the prostate treatment area on the display. At the same time, the transducer emits multiple beams of ultrasound to focus and ablate the treatment area, achieving protein denaturation and necrosis in the treatment area.

[0004] During the treatment, the transducer in the probe will heat up, so a cooling circulator is usually connected to circulate cooling water to cool the transducer. To protect the probe, it is necessary to prevent cooling water from seeping into the probe during treatment and contacting the electronic components inside the probe, causing the probe to short-circuit and stop working.

[0005] Therefore, it is necessary to propose a new solution to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an ultrasonic treatment probe.

[0014] Furthermore, a guide rod is fixedly mounted on the circular shell, a guide plate is movably sleeved on the outer surface of the guide rod, and the guide plate is fixedly connected to the cross bar.

[0015] The beneficial effects of the utility model are:

[0016] 1. In the utility model, by arranging a rubber sheet, a telescopic protective cover and foam, the elastic force of the rubber sheet allows the rubber sheet to be in close contact with the cross bar, thereby reducing the possibility of cooling water entering the handle shell, and even if a small amount of cooling water passes between the rubber sheet and the cross bar, it will enter the inner groove.

[0017] 2. In the utility model, a stepper motor, a drive motor and a screw are arranged. By starting the drive motor, the screw can be rotated, so that the cross bar and the guide plate can be telescopically moved along the axial direction of the cross bar under the guidance of the guide rod, thereby driving the transducer to telescopically move. By starting the stepper motor, the rotating shaft can drive the circular shell to rotate, so that the drive motor, the cross bar and the transducer can rotate together, thereby facilitating the transducer to image and locate the treatment area and focus on ablation.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment: An ultrasonic treatment probe, such as Figure 1-Figure 5 As shown, it includes a handle shell 1, a head shell 3 is installed on the handle shell 1, a water inlet groove 4 and a water outlet groove 5 are opened between the handle shell 1 and the head shell 3, a transducer 7 is arranged inside the head shell 3, a cross bar 8 is connected to the transducer 7, the other end of the cross bar 8 extends to the inside of the handle shell 1, and the cross bar 8 is connected to the handle shell 1 through a driving mechanism, a rubber sheet 9 is installed on the inner wall of the head shell 3 for preliminarily blocking the cooling water from flowing along the surface of the cross bar 8 into the handle shell 1, the rubber sheet 9 and the cross bar 8 are movably connected, an inner groove 10 is opened on the handle shell 1 between the water inlet groove 4 and the water outlet groove 5, a telescopic protective cover 11 is installed in the inner groove 10, and the telescopic protective cover 11 is movably sleeved on the surface of the cross bar 8, and the gap on the surface of the telescopic protective cover 11 is filled with foam 12.

[0026] When using the probe for treatment, since cooling water needs to flow into the head shell 3 to cool the transducer 7, the cooling water may flow along the surface of the cross bar 8 to the handle shell 1 and cause damage to the electronic equipment. Through the elastic force of the rubber sheet 9, the rubber sheet 9 can be in close contact with the cross bar 8, thereby reducing the possibility of cooling water entering the handle shell 1, and even if a small amount of cooling water passes between the rubber sheet 9 and the cross bar 8, it will enter the inner groove 10. Since the cross-section of the telescopic protective cover 11 is wrinkled, multiple protections are formed to further block the cooling water. If the telescopic protective cover 11 is worn out after long-term use, resulting in loose contact between the telescopic protective cover 11 and the cross bar 8, at this time, since the foam 12 is set in a stretched state, due to the elastic recovery effect of the foam 12, the telescopic protective cover 11 will shrink toward the middle as a whole, thereby reducing the inner diameter of the telescopic protective cover 11, and then it can continue to maintain a close contact with the cross bar 8, ensuring a good waterproof effect.

[0027] Further, such as Figure 1 As shown, a transparent membrane sleeve 2 is movably sleeved on the handle shell 1 to seal the head shell 3. The design of the membrane sleeve 2 can prevent cooling water from flowing to the rectum and causing discomfort to the patient.

[0028] Further, such as Figure 1-Figure 3 As shown, a hose 6 is installed on the handle housing 1, and the two hoses 6 are respectively connected to the water inlet trough 4 and the water outlet trough 5. By connecting the hose 6 to an external cooling cycle machine, a cooling water circulation loop can be formed to achieve cooling of the transducer 7.

[0029] Further, such as Figure 3 As shown, the driving mechanism includes a driving motor 14, which is arranged inside the handle housing 1. The output shaft of the driving motor 14 is fixedly sleeved with a screw rod 15, which is threadedly connected to the cross bar 8. The driving motor 14 is connected to the handle housing 1 through a rotating mechanism.

[0030] Furthermore, the rotating mechanism includes a circular ring 20 , which is fixedly mounted inside the handle housing 1 , and a circular shell 13 is rotatably connected to the circular ring 20 , and a driving motor 14 is fixedly mounted inside the circular shell 13 .

[0031] Furthermore, a stepper motor 18 is fixedly installed in the handle housing 1, and a rotating shaft 19 is fixedly sleeved on the output shaft of the stepper motor 18, and the other end of the rotating shaft 19 is connected to the round shell 13. By starting the stepper motor 18, the rotating shaft 19 can drive the round shell 13 to rotate, thereby driving the driving motor 14 to rotate together.

[0032] Furthermore, a guide rod 16 is fixedly mounted on the round shell 13, and a guide plate 17 is movably sleeved on the outer surface of the guide rod 16, and the guide plate 17 is fixedly connected to the cross bar 8. By starting the drive motor 14, the screw rod 15 can be rotated, and under the guidance of the guide rod 16, the cross bar 8 can move with the guide plate 17, so that the transducer 7 can perform telescopic movement.

[0033] During use, the medical staff puts the membrane sleeve 2 on the handle shell 1, and then inserts the head shell 3 into the patient's rectum to treat the patient. By starting the drive motor 14, the screw rod 15 can be rotated, so that the cross bar 8 and the guide plate 17 can be guided by the guide rod 16 along the axial extension and contraction movement of the cross bar 8, thereby driving the transducer 7 to extend and contract. By starting the stepper motor 18, the rotating shaft 19 can drive the round shell 13 to rotate, so that the drive motor 14 can rotate together with the cross bar 8 and the transducer 7, so as to facilitate the imaging positioning and focused ablation of the treatment area by the transducer 7. The external cooling circulation machine is connected through the hose 6, so that the cooling water enters the head shell 3 from the water inlet groove 4 to cool the transducer 7, and then flows out from the water outlet groove 5.

[0034] When the cooling water is inside the head shell 3, due to the elastic force of the rubber sheet 9, the rubber sheet 9 can be in close contact with the cross bar 8, thereby reducing the possibility of cooling water entering the handle shell 1, and even if a small amount of cooling water passes between the rubber sheet 9 and the cross bar 8, it will enter the inner groove 10. Since the cross-section of the telescopic protective cover 11 is wrinkled, multiple protections are formed to further block the cooling water, and the elastic recovery effect of the foam 12 will cause the telescopic protective cover 11 to shrink toward the middle as a whole, so that the telescopic protective cover 11 can continue to maintain a close contact with the cross bar 8, ensuring a good waterproof effect and preventing cooling water from penetrating into the handle shell 1 and causing a short circuit in electronic components.

[0035] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
