Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a universal puncture frame for an ultrasound probe. Background Technology

[0002] Interventional ultrasound has become an important branch of modern ultrasound medicine. In interventional ultrasound procedures, various ultrasound puncture probes and puncture frames attached to the probes are tools of interventional ultrasound. This technology developed based on the advancements in ultrasound imaging to further meet the needs of clinical diagnosis and treatment. Its main function is to perform various procedures such as biopsies, fluid aspiration, punctures, angiography, vascular drainage, drug injection / transfusion, and drug injection into cancerous lesions under real-time ultrasound monitoring or guidance. This can avoid certain surgical procedures while achieving the same results as surgical procedures.

[0003] The applicant has discovered at least the following technical problems in the existing technology: The existing puncture frame fixed to the probe has a relatively fixed placement angle for the puncture needle, resulting in a certain blind zone during the puncture process. The puncture needle cannot freely change its angle and lacks guidance. Furthermore, after a successful puncture, the puncture frame may encounter resistance when separating from the puncture needle, causing the needle tip to shift or dislodge from the blood vessel. This not only increases the complexity of the procedure but may also cause additional pain to the patient. Utility Model Content

[0004] The purpose of this invention is to provide a universal puncture holder for an ultrasonic probe to solve the technical problems existing in the prior art. The preferred technical solutions among the various technical solutions provided by this invention and their numerous technical effects are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An ultrasonic probe universal puncture frame includes a base, fixed wings, and a fixing structure. The top surface of the base is arc-shaped, and its bottom surface contacts the ultrasonic probe. Two fixed wings are symmetrically connected to the top surface of the base, forming a limiting gap between them. A puncture needle can be fixed in the limiting gap and contact the top surface of the base. The puncture needle can rotate relative to the top surface of the base within the limiting gap. The fixing structure is connected to the base and to the ultrasonic probe.

[0007] Preferably, the base is a semi-cylindrical structure, with one flat side of the semi-cylindrical structure serving as the bottom surface and contacting the ultrasound probe, and the arc-shaped side of the semi-cylindrical structure serving as the top surface and contacting the puncture needle.

[0008] Preferably, the fixed wing is a quarter-sphere structure, the top surface of the quarter-sphere structure is a sphere, and the limiting gap is formed between two quarter-sphere structures.

[0009] Preferably, the width of the limiting gap gradually increases from the center towards the front end.

[0010] Preferably, the width of the limiting gap gradually increases from the center to the rear end.

[0011] Preferably, the width of the limiting gap gradually increases from the center upwards.

[0012] Preferably, the fixing structure is an elastic strap, and both ends of the elastic strap are connected to the base.

[0013] Preferably, the elastic strap is provided with marking scales.

[0014] Preferably, the fixing structure is a fixing frame, which is sleeved on the ultrasonic probe, and the base is connected to the fixing frame.

[0015] Preferably, the base is integrally connected to the fixed wing.

[0016] The beneficial effects of this utility model are as follows: by setting the top surface of the base to be an arc surface, the puncture needle that is clamped and limited in the limiting gap can rotate relative to the top surface of the base as the fulcrum, so that the placement of the puncture needle can be flexibly adjusted according to the actual situation, which is equivalent to flexibly adjusting the puncture angle.

[0017] The fixed wings located on the left and right sides can control the direction of travel of the puncture needle, so that the puncture needle is always fixed in the limiting gap in the forward direction, and the limiting gap plays a guiding role in the direction of travel of the puncture needle.

[0018] The two fixed wings can cooperate with the curved top surface of the base to form three-point support for the puncture needle, which can make the puncture more stable and avoid danger while ensuring that the angle can be adjusted at will;

[0019] In addition, after a successful puncture, the puncture needle can more easily separate from the universal puncture frame of the ultrasound probe, effectively reducing the resistance encountered during separation and improving patient comfort. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, it should be understood that the terms "center," "side," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] In the description of this utility model, it should also 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; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Reference Figures 1 to 4This utility model provides a universal puncture frame for an ultrasound probe, including a base 1, fixed wings 2, and a fixing structure 3. The top surface of the base 1 is an arc surface and its bottom surface is in contact with the ultrasound probe. Two fixed wings 2 are symmetrically connected to the top surface of the base 1 and form a limiting gap 4 between them. The puncture needle can be fixed in the limiting gap 4 and in contact with the top surface of the base 1. The puncture needle can rotate relative to the top surface of the base 1 in the limiting gap 4. The fixing structure 3 is connected to the base 1 and connected to the ultrasound probe.

[0033] By setting the top surface of the base 1 as an arc surface, the puncture needle clamped and limited in the limiting gap 4 can rotate relative to the top surface of the base 1 as a fulcrum, thereby flexibly adjusting the placement of the puncture needle according to the actual situation, which is equivalent to flexibly adjusting the puncture angle.

[0034] The fixed wings 2 located on the left and right sides can control the direction of travel of the puncture needle, so that the puncture needle is always fixed in the limiting gap 4 in the forward direction, and the limiting gap 4 plays a guiding role in the direction of travel of the puncture needle.

[0035] The two fixed wings 2 can cooperate with the arc-shaped top surface of the base 1 to form a three-point support for the puncture needle. This allows for more stable puncture while ensuring that the angle can be adjusted at will, thus avoiding danger.

[0036] In addition, after a successful puncture, the puncture needle can more easily separate from the universal puncture frame of the ultrasound probe, effectively reducing the resistance encountered during separation and improving patient comfort.

[0037] As an optional implementation, the base 1 is a semi-cylindrical structure, which has a plane and an arc surface, with the plane and the arc surface located on both sides respectively;

[0038] The flat side of the semi-cylindrical structure is the bottom surface and is in contact with the ultrasonic probe, thereby ensuring the stable placement of the base 1;

[0039] The semi-cylindrical structure has an arc surface on one side as its top surface, which can contact the puncture needle. The puncture needle can rotate to a certain extent relative to the arc surface of the semi-cylindrical structure.

[0040] As an optional implementation, the fixed wing 2 is a quarter-sphere structure, the top surface of both quarter-sphere structures is spherical, the bottom surface of both quarter-sphere structures is connected to the base 1, the facades of the two quarter-sphere structures are symmetrically arranged, and the two quarter-sphere structures form a limiting gap 4 between the two facades through the arrangement of the two facades.

[0041] As an optional implementation, since the main purpose of the two fixed wings 2 is to ensure the forward direction of the puncture needle, the width of the limiting gap 4 is matched with the diameter of the puncture needle. In addition, according to actual usage requirements, the ultrasonic probe universal puncture frame can be used with puncture needles of different diameters. Therefore, in this embodiment, the width of the limiting gap 4 is preferably gradually increased from the center to the front end, gradually increased from the center to the rear end, and gradually increased from the center to the upper end. With this setting, the width of the limiting gap 4 gradually widens from the axis to the outer surface, thereby effectively matching puncture needles of different diameters. The widest part can match the thickest type of puncture needle, and the narrowest part can match the narrowest signal puncture needle.

[0042] Furthermore, since the puncture needle always needs to move forward, and the puncture angle under ultrasound imaging is only between 0° and 90°, it is only necessary to consider the structural design along the center to the front end. That is, the base 1 only needs a quarter-cylinder structure design. However, for aesthetics and ease of use, this embodiment ultimately chose a semi-cylinder structure as the structural form of the base 1.

[0043] As an optional implementation, the fixing structure 3, as a structure for relatively fixing two objects, has a variety of structural forms to choose from;

[0044] In this embodiment, the fixing structure 3 can preferably be an elastic band. The two ends of the elastic band are connected to the base 1. The elastic band is preferably provided with marking scales. When the puncture frame is fixed to the ultrasound probe by the fixing structure 3, it can be positioned by the marking scales to ensure that the axis of the puncture needle can eventually be located on the center line of the ultrasound probe.

[0045] In this embodiment, the fixing structure 3 can also be preferably a fixing frame, which is sleeved on the ultrasonic probe. The base 1 is connected to the fixing frame. The structure of the fixing frame itself is a relatively conventional existing technology, so it will not be described in further detail.

[0046] As an optional implementation, the base 1 and the fixed wing 2 are integrally connected, and the base 1 and the fixed wing 2 are integrally formed, which can enhance the overall structural strength.

[0047] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
