Description

Technical Field

The utility model relates to the technical field of ultrasonic equipment, in particular to ultrasonic equipment and an ultrasonic probe thereof.

Background

In an ultrasound probe of an ultrasound device, the ultrasound waves of a transducer propagate through an acoustic window. Taking a rotation probe in a cavity capable of realizing 360-degree detection as an example, the rotation probe mainly drives a transducer to perform 360-degree circumferential scanning through a motor, so that the observation of a structure is realized.

The probe housing includes an interconnecting acoustic window and a connecting housing. The acoustic window mounted at the front end must be capable of facilitating propagation of ultrasonic waves.

Detailed Description

The utility model discloses an ultrasonic probe which reduces risks of scratching patients and risks of oil leakage. The utility model also provides ultrasonic equipment.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-8, an embodiment of the present utility model provides an ultrasonic probe including a handle mechanism, a probe mechanism, a transducer, and a driving mechanism.

Wherein the handle mechanism has a handle housing 120; the probe mechanism has a probe housing 110, the probe housing 110 having an acoustic window 114 and a connection housing 112, the end of the connection housing 112 facing away from the acoustic window 114 being connected to a handle housing 120.

One of the acoustic window 114 and the connection housing 112 is a first component made of a first material and the other component is a second component made of a second material, the first material having a melting point lower than the second material.

Wherein the first part and the second part are integrally injection molded; or after the second part is processed, the first part is formed by injection molding and is connected with the second part.

Also, the transducer is disposed within the acoustic window 114, and ultrasonic waves emitted and received by the transducer can pass through the acoustic window 114; the drive mechanism is used to drive the transducer to rotate within the acoustic window 114.

According to the ultrasonic probe provided by the embodiment of the utility model, as the first component and the second component are integrally injection molded; or after the second part is processed, the first part is formed by injection molding and is connected with the second part; so that the acoustic window 114 and the connection housing 112 are connected by injection molding.

It can be appreciated that, due to the injection molding operation, the acoustic window 114 and the connection housing 112 do not need to be separately processed, so that a break difference at the connection position of the acoustic window 114 and the connection housing 112 caused by processing errors is avoided, the external flatness at the connection position of the acoustic window 114 and the connection housing 112 is reduced, and the risk of scratching a patient is reduced; and the connection operation through the gluing process is avoided, so that the oil leakage risk caused by the falling of the glue layer is avoided.

The ultrasonic probe can be an intracavity probe, an abdomen probe or other types of probes, and the ultrasonic probes are not accumulated one by one and are all within the protection range.

In the embodiment where the first part is integrally injection molded with the second part, the melting point of the first material is lower than the melting point of the second material, so that the initial ambient temperature for injection molding may be higher than the melting point of the second material, or may be lower than the melting point of the second material, or even lower than the melting point of the first material. When the initial injection molding ambient temperature is higher than the melting point of the second material, the melting point of the second material is higher in the injection molding process of the first part and the second part, so that the second part can be molded preferentially, and the first part is molded again.

Further, in embodiments in which the first component is injection molded and connected to the second component after the second component is finished, the temperature of the injection molding of the first component may be higher than the melting point of the first material and lower than the melting point of the second material in order to avoid the influence of the first component on the second component during the injection molding process. Through the arrangement, the second part is ensured to be stable in structure all the time in the injection molding process of the first part.

Of course, in embodiments where the first part is injection molded and attached to the second part after the second part is finished, the temperature of the injection molding of the first part may also be made higher than the melting point of the second material. Of course, the temperature of the injection molding of the first part is also higher than the melting point of the first material. In the injection molding process of the first component, the connection position of the second component and the first component is locally melted, so that the first component and the second component are better connected.

In this embodiment, the acoustic window 114 is made of a first material, and the connection housing 112 is made of a second material. That is, the connection housing 112 is made of a second material having a higher melting point, and the acoustic window 114 is made of a first material having a lower melting point.

With the above arrangement, in the embodiment in which the connection structure between the acoustic window 114 and the connection housing 112 is "the second component is processed and then the first component is injection molded and connected with the second component", the connection housing 112 with a relatively complex structure can be processed as the second component, and then the processing of the acoustic window 114 and the connection operation between the acoustic window 114 and the connection housing 112 are completed by injection molding. By the arrangement, the first component is convenient to process.

Of course, the acoustic window 114 may be made of the second material, and the connection housing 112 may be made of the first material.

Further, after the second part is processed, the first part is formed by injection molding and is connected with the second part; the connecting end of the second component is provided with a second matching structure, and part of materials of the first component are contacted with the second matching structure in the injection molding process to form a first matching structure; the first matching structure is matched with the second matching structure in a concave-convex mode.

Through the arrangement, the joint of the sound window 114 and the connecting shell 112 is matched in a concave-convex mode, so that the contact area of the joint of the sound window 114 and the connecting shell 112 is increased, and the connection strength of the sound window 114 and the connecting shell 112 is further improved.

Preferably, the first mating structure comprises a first annular portion and the second mating structure comprises a second annular portion; the first annular part and the second annular part are mutually sleeved. Namely, the first matching structure and the second matching structure are mutually sleeved and connected.

In this embodiment, the acoustic window 114 is a first component and the connection housing 112 is a second component. Thus, the acoustic window 114 has a first annular portion and the connection housing 112 has a second annular portion.

Further, the inner wall of the first annular portion is in contact with the outer wall of the second annular portion. That is, the first annular portion is sleeved outside the second annular portion. That is, during the process of connecting the first member to the second member by injection molding, a part of the material of the first material is covered outside the second annular portion by injection molding, thereby forming the first annular portion.

Of course, the outer wall of the first annular portion may be brought into contact with the inner wall of the second annular portion. That is, the second annular portion is sleeved outside the first annular portion, which is not specifically described herein and is within a protection range.

In order to achieve the concave-convex fit, the second annular portion has a first through hole portion, and an inner wall of the first annular portion has a first protruding portion penetrating into the first through hole portion.

The first annular portion may have a second through hole portion, and the inner wall of the second annular portion may have a second protruding portion penetrating into the second through hole portion.

Of course, the connection of the acoustic window 114 to the connection housing 112 may also be connected by other male and female mating structures. For example, one of the first annular portion and the second annular portion has an annular protrusion, and the other of the first annular portion and the second annular portion has an annular groove, and the annular protrusion is in concave-convex engagement with the annular groove. Alternatively, one of the first annular portion and the second annular portion has a projection block, and the other of the first annular portion and the second annular portion has a recess portion, the projection block being in concave-convex engagement with the recess portion.

For ease of processing, the handle housing 120 and the connection housing 112 are secured by an adhesive seal. That is, the handle housing 120 and the connection housing 112 are separately processed and then fixed by adhesive sealing connection. Other connection means, such as threaded bolting or snap-in connection, etc. may also be used.

The handle housing 120 and the connection housing 112 may also be formed as a unitary structure. That is, the handle housing 120 and the connection housing 112 are integrally formed by injection molding, turning, or the like.

In this embodiment, the ultrasound probe further has a cable 140 and a wire sheath 130 located at the connection between the cable 140 and the handle housing 120; the wire guard 130 is threadedly coupled to the handle housing 120.

Specifically, one end of the cable 140 is connected with the handle housing 120, and the cable housing 130 is in threaded connection with the handle housing 120 through the cable housing 130 arranged at the connection position of the cable 140 and the handle housing 120, so that the cable housing 130 protects the connection position of the cable 140 and the handle housing 120, and the connection strength and the service life are improved.

The other end of the cable 140 may be provided with a plug member 150 connected to the apparatus main body of the ultrasonic apparatus, or the other end of the cable 140 may be directly connected to the apparatus main body of the ultrasonic apparatus.

Preferably, the driving mechanism includes a hollow rotating shaft 220 and a driving device for driving the hollow rotating shaft 220 to rotate, the driving device is disposed in the handle housing 120, one end of the hollow rotating shaft 220 is connected with the driving device, and the other end of the hollow rotating shaft 220 extends into the acoustic window 114: the transducer is coupled to the outer wall of the hollow shaft 220.

Wherein the interior of the hollow shaft 220 is used for routing to facilitate connection of the transducer to other components.

The driving device may include a motor (stepper motor) and a transmission gear, and the transmission gear is driven to rotate by the driving end of the motor, so as to drive the hollow rotating shaft 220 to rotate.

The ultrasound probe provided in this embodiment further includes a base 230 disposed within the handle housing 120 and/or the connection housing 112; the hollow shaft 220 is in a rotational fit with the base 230. The base 230 may be provided with a bearing, and the hollow shaft 220 is rotatably disposed on the base 230 through the bearing.

In embodiments where the base 230 is disposed within the connection housing 112, by providing the base 230, it is ensured that a separate cavity is formed within the probe housing 110 to facilitate filling of the interior with fluid.

In this embodiment, the base 230 may be a handle base. A motor base may be additionally provided in the handle housing 120 to facilitate the fixation of the motor in the driving device. The handle base and the motor base can be fixedly connected. Or may be independent of each other.

Further, a pan plug sealing ring 210 is provided between the hollow shaft 220 and the base 230. The sealing performance of the cavity is improved.

In this embodiment, the base 230 encloses the interior cavity of the probe housing 110 as a main cavity; the base 230 has a liquid filling hole to which a closing member is detachably attached. The main cavity is filled with liquid Kong Fangbian.

Wherein the closing means comprises a blocking plug 270 for blocking the liquid injection hole and a locking screw 260 for positioning the blocking plug 270 opposite to the base 230.

The ultrasonic probe provided by the embodiment of the utility model further comprises a compensation device arranged on one surface of the base 230, which is opposite to the probe shell 110, wherein a compensation cavity with variable volume is arranged in the compensation device, and the compensation cavity is communicated with the main cavity. That is, when the ambient temperature around the ultrasonic probe changes, the volume of the liquid inside the main cavity changes. In order not to influence the stable operation of the ultrasonic probe, the compensation cavity of the compensation device is communicated with the main cavity by setting the value compensation device, and the total volume of the compensation cavity and the main cavity is adjustable due to the variable volume of the compensation cavity.

Since the compensating device is disposed on the surface of the base 230 facing away from the probe housing 110, the elastic change of the compensating device will not affect the volume of the main cavity.

The compensation device can be made of elastic materials, and the volume of the compensation cavity is variable through the self elastic change of the compensation device. That is, when the ambient temperature of the ultrasonic probe changes, the volume of the liquid in the main cavity changes, so that the hydraulic pressure in the main cavity changes, and the compensation device is driven to elastically deform, so that the volume of the compensation cavity changes.

In this embodiment, the compensation device includes a compensation body 250 and a pressing block 240. The compensating body 250 is fixed to the base 230 by the pressing block 240.

The embodiment of the utility model also provides ultrasonic equipment, which comprises an equipment main body and an ultrasonic probe 100, wherein the ultrasonic probe 100 is any ultrasonic probe.

Since the above-mentioned ultrasonic probe has the above-mentioned technical effects, the ultrasonic apparatus having the above-mentioned ultrasonic probe should have the same technical effects as well, and will not be described in detail herein.

In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
