Problems solved by technology

[0007] As we all know, the longer the heart surgery time and the longer the heart stop time, the greater the harm to the patient. Therefore, if the valve cleaning time is longer during surgery, it will cause great harm to the patient.
[0008] In the percutaneous interventional valve replacement, the prolongation of the valve cleaning time is more serious and fatal to the patient. This is because during the interventional valve replacement operation, it is necessary to support the patient's stenosis and calcified valve with an expansion balloon. At the same time, measure on the angiography machine and select the type of valve to be implanted. At this time, because the patient's own valve has been stretched, a large amount of regurgitation will occur, causing the patient's blood pressure to drop rapidly. If the valve cannot be implanted as soon as possible, the patient's may be life-threatening at any time
In this case, it is impossible to extend the cleaning time to make up for the difference in cleaning effect caused by individual differences. However, there has been no best way to solve this problem. Safety factor for small cleaning times

Embodiment 1

[0061] Such as figure 1 As shown, the handheld high-frequency vibration cleaner provided in this embodiment includes, from bottom to top, a holding component 110 , a vibration generating source 120 and a handle 130 .

[0062] The vibration generating source 120 is provided with a housing 121 outside, which is generally cylindrical in shape. The top surface of the housing 121 is fixedly connected to the handle 130 , and the bottom surface of the housing 121 is provided with an escape opening for avoiding the retaining part 110 .

[0063] The shell 121 is provided with a voice coil motor and a matching driving circuit. The voice coil motor includes a coil and a magnet that cooperate with each other. The vibration frequency of the coil is 100-1000 Hz. A frequency adjustment switch is provided in the drive circuit, and the frequency adjustment switch button is set on the casing 121 (not shown in the figure), and the vibration frequency of the coil can be continuously adjusted thro...

Embodiment 2

[0077] The only difference between this embodiment and Embodiment 1 is that the angle between the extension direction of the handle 230 and the extension direction of the clamping arm is 90 degrees.

[0078] Such as image 3 As shown, the housing 221 is generally cylindrical, the clamping arm 211 and the clamping arm 212 are arranged at the bottom of the housing 221, and the whole extends along the vertical direction in the figure, the handle 230 is fixed on the side wall of the housing 221, and extends along the horizontal direction. direction extension.

Embodiment 3

[0080] The only difference between this embodiment and Embodiment 1 is that the structure of the part where the end of the clamping arm cooperates with the instrument to be cleaned is different.

[0081] In this embodiment, the end of the clamping arm is a bifurcated structure, and the fork of the bifurcated structure forms a card slot, and the opening direction of the card slot is upward. When clamping the instrument to be cleaned, the instrument to be cleaned can be hung on the card slot to avoid During cleaning, disengage the clamping arms.

Abstract

The invention discloses a handheld high-frequency vibration type cleaner for an implantable medical appliance. The handheld high-frequency vibration type cleaner comprises a vibration generation source, a gripping part and a handle, wherein the vibration generation source comprises a stator and a rotor matched with each other; the gripping part is fixed opposite to the rotor and is used for holding to-be-cleaned equipment; the handle is fixed opposite to the stator; the vibration frequency of the rotor is 100-1000Hz; the vibration generation source comprises a voice coil motor and a matched drive circuit; a frequency regulation switch is arranged in the drive circuit. According to the high-frequency vibration type cleaner provided by the invention, the intra-operative waiting time of a patient can be greatly shortened, so that the ischemic time of heart, brain and other organs of the patient due to low blood pressure is greatly shortened, and the cerebral apoplexy risk of the patient is reduced. Meanwhile, individual difference of manual operation is avoided, a good cleaning effect is guaranteed, the condition that the patient is injured by residual toxicity of the valve is avoided, and the effect after curing is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hand-held high-frequency vibration cleaner for implanted medical instruments. Background technique [0002] In the current heart valve replacement surgery, the valves used are divided into two categories: biological valves and mechanical valves. The surgery is divided into surgical valve replacement (SAVR) and percutaneous valve replacement (TAVR). For percutaneous valve replacement Because the diameter of the valve must be compressed before the operation so that it can pass through the blood vessel to the implantation site, biomaterial valves are basically used. [0003] However, the current storage methods for biological valves are almost always sealed and preserved by soaking them in a sterilizing solution with a cross-linking agent to prevent the biological material in the valve from degrading and being contaminated. However, these preservation solutions are to...
