Description

an ultrasonic probe

technical field

The invention relates to the technical field of medical instruments, and more specifically, the invention relates to an ultrasonic probe.

Background technique

At present, in the clinic of the hospital, the application of ultrasonic diagnosis is very extensive. Ultrasonic diagnosis is a diagnostic technology that transmits ultrasonic waves to the subject through an ultrasonic probe, receives reflected waves, and generates ultrasonic images based on the received ultrasonic signals.

Existing ultrasonic probes are generally straight-handle type. As shown in Figure 1, the axis of the handle 2 of the existing ultrasonic probe is parallel to the axis of the head 1. When using the existing ultrasonic probe for ultrasonic diagnosis, it needs to be held by hand. Only handle 2 can be operated, and the straight-handled ultrasonic probe is very cumbersome to hold. Therefore, the existing ultrasonic probe has disadvantages such as uncomfortable holding, hard force, inconvenient use and inflexibility.

Later, people installed a puncture frame on the ultrasonic probe, and installed a puncture needle on the puncture frame. While observing the ultrasonic image of the subject through the ultrasonic probe, the puncture needle was punctured into the subject. With the combined use of the puncture needle, operations such as tissue extraction, contrast examination or drug treatment can be conveniently performed on the patient.

However, since the existing ultrasonic probes are generally of straight handle type, when using the existing ultrasonic probes to puncture the patient, the existing ultrasonic probes also have the disadvantages of being uncomfortable to hold, hard to use, inconvenient and inflexible to use, etc. shortcoming.

In addition, in order to cooperate with the installation and use of the puncture frame, the head of the existing ultrasonic probe is generally provided with a large installation groove, so that the strength of the ultrasonic probe is reduced, and the use of the existing ultrasonic probe is also limited. Some ultrasonic probes cannot be used alone, but can only be used together with the puncture frame, thereby reducing the practicability of the existing ultrasonic probes. In particular, the puncture direction of the puncture needle is in the same direction as the axis of the handle, that is, generally parallel to each other, and the operation space for puncture overlaps with the holding space, which makes the puncture operation very inconvenient.

Contents of the invention

The technical problem to be solved by the present invention is to provide an ultrasonic probe that is comfortable to hold, easy to use, and easy to use.

In order to solve the problems of the technologies described above, the technical scheme adopted in the present invention is as follows:

An ultrasonic probe comprising a head and a handle, the rear end of the head is fixedly connected to the front end of the handle, and it is characterized in that it also includes a snap-in mechanism for installing a puncture frame, and the snap-in mechanism is installed on the head ; The axis of the handle forms a certain angle with the axis of the head.

Therefore, the ultrasonic probe is comfortable to hold, easy to use, Easy to use and flexible. When the axis of the handle forms a certain angle with the axis of the head, the axis of the handle forms a certain angle with the puncture direction of the puncture needle, and the axis of the handle and the puncture direction stagger each other (that is, they are not on the same straight line), so that the puncture The operating space and the space for holding the handle are staggered mutually, thereby facilitating the puncturing operation. In addition, since the head of the ultrasonic probe is provided with a clamping mechanism, the puncture frame is detachably installed on the head of the ultrasonic probe through the clamping mechanism, so the ultrasonic probe can be used alone or installed The puncture operation is performed on the puncture frame, thereby improving the practicability of the ultrasonic probe.

At the same time, the head of the ultrasonic probe does not need to be provided with a large installation groove. Therefore, the strength of the ultrasonic probe is good, and the shape of the ultrasonic probe is smoothly transitioned, so that it is convenient for intracavitary inspection and reduces the pain of the inspected. Discomfort.

More importantly, when the ultrasonic probe is equipped with a puncture needle, since the axis of the handle of the ultrasonic probe forms a certain angle with the axis of the head, the axis of the handle of the ultrasonic probe and the puncture direction of the puncture needle also form a certain angle. A certain angle, like this, the operation space of puncturing and the space of holding the handle are just staggered mutually, thereby facilitates the carrying out of puncturing operation.

As a further improved technical solution of the present invention, a protective cover may be covered on the outer surface of the head.

When the puncture frame needs to be assembled, first, a protective cover can be put on the outer surface of the head, and then the puncture frame is installed on the head, so that the protective cover is located between the head and the puncture frame;

When the puncture operation is performed, the puncture needle will not pierce the protective cover, thereby protecting the head. At the same time, it also prevents the head from being polluted and is convenient for disinfection.

When the ultrasonic probe needs to be reused, firstly, the puncture frame is disassembled from the head and subjected to special disinfection; then, the protective cover is removed from the head, and the head is subjected to routine disinfection; then, Put a new protective sheath on the routinely sterilized head; finally, install the specially sterilized piercing frame on the head so that the ultrasound probe can be used again.

It can be seen from the above that after using the protective cover, the disinfection of the ultrasonic probe becomes relatively simple. It only needs to carry out special disinfection treatment on the puncture frame, and carry out routine disinfection treatment on the head of the ultrasonic probe. Therefore, the disinfection treatment of the ultrasonic probe is convenient.

The beneficial effect that the present invention compares prior art is:

Since the axis of the handle of the ultrasonic probe is at a certain angle to the axis of the head, the structure of the ultrasonic probe is designed according to the physiological structure and usage habits of the human hand, and conforms to the design concept of ergonomics. Therefore, this ultrasonic probe The ultrasonic probe has the advantages of comfortable grip, good force, convenient and flexible use, etc. When the axis of the handle forms a certain angle with the axis of the head, the axis of the handle forms a certain angle with the puncture direction of the puncture needle, and the axis of the handle and the puncture direction stagger each other (that is, they are not on the same straight line), so that the puncture The operating space and the space for holding the handle are staggered mutually, thereby facilitating the puncturing operation. In addition, since the head of the ultrasonic probe is provided with a clamping mechanism, the puncture frame is detachably installed on the head of the ultrasonic probe through the clamping mechanism, so the ultrasonic probe can be used alone or installed The puncture operation is performed on the puncture frame, thereby improving the practicability of the ultrasonic probe.

At the same time, the ultrasonic probe also has the advantages of simple structure, reasonable design, low manufacturing cost, and easy popularization.
