Description

Technical Field

[0001] This utility model relates to the field of ultrasonic probe marking pen technology, and in particular to a device for assisting in the positioning of ultrasonic probe marking pens. Background Technology

[0002] As is well known, before surgery, an ultrasound probe is used to explore the human body and determine the anatomical location based on the structures at the exploration site. In order to accurately and quickly determine the location, while the ultrasound exploration is being performed, a marker is used to mark the anatomical structures under the skin at the corresponding locations, such as arteries, veins, and intervertebral sutures.

[0003] Currently, there are two types of marking pens. One type involves manually holding the pen and pressing it against the ultrasound probe to make a mark, which is labor-intensive. The other type uses a pen holder attached to the ultrasound probe, allowing the pen to move with the probe. To prevent the pen from touching the skin during vertical probe operation, the pen's tilt angle and length need to be specifically calibrated. The ultrasound probe must be tilted to allow the pen to contact the skin for marking. However, if the pen is not properly installed or if the probe is tilted incorrectly, unwanted skin may be marked. Furthermore, some procedures require the ultrasound probe to be tilted for accurate detection.

[0004] Therefore, structural improvements are needed for the existing ultrasonic pen holder. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a device for positioning an auxiliary ultrasonic probe marker pen that can be placed to correct mismarks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for positioning an ultrasonic probe marker pen includes a base plate for mounting on an ultrasonic probe. A cover plate is detachably mounted on the base plate, and a movable cavity is formed on the cover plate. A sliding member is disposed within the movable cavity, and a bevel is provided on the side of the sliding member. A pen refill, which is a plastic pen refill that can be bent under pressure, is disposed at one end of the sliding member. The pen tip of the pen refill is located outside the cover plate. A spring is provided between the sliding member and the movable cavity, and under the action of the spring, the pen refill tends to retract into the movable cavity. An arc-shaped baffle is provided on the side of the cover plate, and a limiting groove is provided on the baffle. One end of the limiting groove is directly opposite the pen tip of the pen refill. A pressing block is placed at the bevel, and a guide block with a bevel is provided at one end of the pressing block. The bevel of the guide block fits against the surface of the bevel. The other end of the pressing block passes through the cover plate and is located outside. Under the action of the spring, the other end of the pressing block tends to pop outward.

[0008] Preferably, the end of the slider connected to the pen refill is provided with a mating hole, and a soft rubber part is provided at the opening of the mating hole. The other end of the pen refill relative to the pen tip is inserted into the mating hole, and the soft rubber part clamps the pen body of the pen refill.

[0009] Preferably, the cover plate has a skirt on its side, and the base plate has a pair of slots. The cover plate is inserted into the pair of slots through the skirt, so that the cover plate can be detachably installed on the base plate.

[0010] Preferably, the base plate has through holes on its side, and the base plate is tied to the ultrasonic probe by straps passing through the through holes.

[0011] Thanks to the above-mentioned design, this invention allows for the concealed storage of the pen refill through the inclusion of a movable cavity, a sliding component, and a spring. When not in use, the pen refill is prevented from being exposed and causing mismarking, giving doctors greater peace of mind when operating the ultrasound probe. Furthermore, by pressing the pen refill out, a baffle forces the refill to bend, ensuring that it rests precisely on the skin where the ultrasound probe contacts the skin. Upon releasing the pressure, the refill automatically springs back, making the overall operation very convenient. Attached Figure Description

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection.

[0019] like Figures 1 to 4As shown, this embodiment provides a device for positioning an auxiliary ultrasonic probe marker pen, including a base plate 1 for mounting on an ultrasonic probe 100. A cover plate 2 is detachably mounted on the base plate 1, and a movable cavity 3 is formed on the cover plate 2. A sliding member 4 is disposed within the movable cavity 3, and a bevel 5 is provided on the side of the sliding member 4. A pen refill 6 is provided at one end of the sliding member 4. The pen refill 6 is a plastic pen refill that can be bent under pressure. The pen tip of the pen refill 6 is placed outside the cover plate 2. A spring 7 is provided between the sliding member 4 and the movable cavity 3, and under the action of the spring 7... The pen refill 6 always tends to retract into the movable cavity 3. An arc-shaped baffle 8 is provided on the side of the cover plate 2. A limiting groove 9 is provided on the baffle 8. One end of the limiting groove 9 is directly opposite the pen tip of the pen refill 6. A pressing block 10 is placed at the inclined opening 5. One end of the pressing block 10 is provided with a guide block 11 with an inclined surface. The inclined surface of the guide block 11 is in contact with the surface of the inclined opening 5. The other end of the pressing block 10 passes through the cover plate 2 and is placed outside. Under the action of the spring 7, the other end of the pressing block 10 always tends to pop outward.

[0020] This embodiment primarily utilizes the movable cavity 3, the sliding member 4, and the spring 7 to conceal and store the pen refill 6. When not in use, this prevents the pen refill 6 from being exposed and causing mismarking, giving doctors greater peace of mind when operating the ultrasound probe. Simultaneously, by pressing, the pen refill 6 is pushed out, and the baffle 8 forces the pen refill 6 to bend, ensuring it rests precisely on the skin where the ultrasound probe 100 contacts. It automatically springs back after being released, making the overall operation very convenient. In practical use, by default, the sliding member 4, cover plate 2, and base plate 1 are already installed. Simply install the base plate 1 onto the corresponding ultrasound probe 100 for immediate use. When marking is required, simply press down the pressing block 10. The pressing block 10 pushes vertically inward, causing the guide block 11, originally located at the top of the inclined opening 5, to move towards the bottom of the inclined opening 5. This moves the sliding member 4 towards the other end of the movable cavity 3, gradually extending the pen tip 6. The pen tip 6 then enters the limiting groove 9 of the baffle 8. Continuing to move, the curved shape of the baffle 8, combined with the extended length of the pen tip 6 and the fact that it is made of plastic, causes the slender pen tip 6 to bend, guiding it along the limiting groove 9 until it touches the skin at the ultrasound probe 100, allowing marking to be performed. After marking is complete, release the pressing block 10. The spring 7 will reset the sliding member 4, and the pen tip 6 will return to its initial position.

[0021] Furthermore, when the pen refill 6 is damaged or out of ink, a detachable connection between the pen refill 6 and the sliding member 4 needs to be designed. Therefore, in this embodiment, the end of the sliding member 4 connected to the pen refill 6 is provided with a mating hole 12, and a soft rubber part 13 is provided at the opening of the mating hole. The other end of the pen refill 6 relative to the pen tip is inserted into the mating hole 12, and the soft rubber part 13 clamps the pen body of the pen refill 6. In this way, when the pen refill needs to be replaced, simply remove the cover plate 2 from the base plate 1, the sliding member 4 compresses the spring 7 and disengages from the movable cavity 3, then directly pull out the pen refill 6, insert a new pen refill 6, put the spring 7 back in place, return it to its original position, and let the pen tip of the pen refill 6 pass out from one end of the cover plate 2. In this way, the cover plate 2 can be reinstalled on the base plate 1.

[0022] Furthermore, regarding the installation structure between the cover plate 2 and the base plate 1, specifically, in this embodiment, the cover plate 2 is provided with a skirt 14 on its side, and the base plate 1 is provided with a matching slot 15. The cover plate 2 is inserted into the matching slot 15 through the skirt 14, so that the cover plate 2 can be detachably installed on the base plate 1.

[0023] Furthermore, regarding the installation between the base plate 1 and the ultrasonic probe 10, the base plate 1 in this embodiment is provided with a through hole 16 on its side. The base plate 1 is tied to the ultrasonic probe 100 by passing a strap (not shown in the figure) through the through hole 16.

[0024] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
