Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and in particular to an ultrasonic probe capable of assisting percutaneous renal puncture. Background Art

[0002] In modern medicine, ultrasound technology is widely used in various diagnostic and treatment processes due to its non-invasive, real-time, and repeatable advantages. Percutaneous renal biopsy, as an important diagnostic and treatment method, plays a key role in the diagnosis and treatment of kidney diseases.

[0003] During percutaneous renal puncture, accurate positioning of the puncture needle is crucial. Currently, the commonly used method is to place the puncture needle close to the ultrasound probe. However, this approach has several significant drawbacks.

[0004] First, the puncture needle is prone to misalignment or displacement. During actual operation, because the puncture needle is simply placed close to the ultrasound probe without effective fixation, it is easily affected by external factors such as slight movement of the patient and improper operation by medical staff. Once the puncture needle is misaligned or displaced, it will greatly affect the accuracy of the puncture and may even cause puncture failure, causing unnecessary pain and risk to the patient.

[0005] Secondly, this method is difficult for medical staff to operate. When performing percutaneous renal puncture, medical staff need to consider both the position of the ultrasound probe and the direction of the puncture needle, which requires a high level of skill and experience. Furthermore, due to the instability of the puncture needle, medical staff must be extremely careful during the operation to prevent the needle from deviating from the target position. This not only increases the time and difficulty of the operation, but also may affect the medical staff's confidence and the effectiveness of the operation.

[0006] Furthermore, existing percutaneous renal puncture methods present certain safety risks. If the puncture needle fails to accurately reach the target location, it may damage surrounding tissues and organs, leading to serious complications. For example, it may damage vital structures around the kidney, such as blood vessels and nerves, leading to adverse consequences such as bleeding and infection. Utility Model Content

[0007] The utility model aims to solve the above technical problems and provides an ultrasound probe that can assist percutaneous renal puncture.

[0008] In order to solve the above technical problems, the technical solution provided by the utility model is: an ultrasound probe that can assist percutaneous renal puncture, including a handle, one end of the handle is connected to a power cord, and the other end is connected to a contact head, a groove is provided on one side of the handle, a cylinder for accommodating a puncture needle is provided in the groove, and a limiting structure is provided in the cylinder.

[0009] Furthermore, the groove is an open groove, one side of the cylinder is provided with an opening corresponding to the open groove, and the angle between the center line of the open groove and the center line of the handle is an acute angle.

[0010] Furthermore, the limiting structure includes multiple arc plates, one end of which is fixedly connected to the inner wall of the cylinder, and the other end does not contact the inner wall of the cylinder. The multiple arc plates are divided into at least two columns and are distributed in a ring shape on the inner wall of the cylinder.

[0011] Furthermore, the symmetrically arranged arc plates are bent in reverse, and the arc plates are made of elastic material, and the distance between the symmetrically arranged arc plates is smaller than the diameter of the puncture needle.

[0012] Furthermore, the arc-shaped plates are divided into two rows and are symmetrically distributed on the inner wall of the cylinder.

[0013] Furthermore, the arc-shaped plates are divided into three rows and are evenly distributed on the inner wall of the cylinder.

[0014] The advantages of this utility model compared with the prior art are:

[0015] 1. Improve puncture accuracy

[0016] By placing the puncture needle in the cylinder on the side of the handle and using a limiting structure to fix and limit the puncture needle, displacement of the puncture needle during operation is avoided, ensuring that the ultrasound probe can always accurately see the puncture needle, thereby greatly improving the accuracy of puncture.

[0017] 2. Enhance operational stability

[0018] The design of the limiting structure allows the puncture needle to move toward the skin after being inserted into the cylinder. The curved plate clamps the puncture needle so that it cannot move left or right during the movement. The doctor does not need to worry too much about the position change of the puncture needle during the operation, thereby enhancing the stability of the operation.

[0019] 3. Convenient for medical staff to grasp

[0020] The design of the puncture needle set on the side of the handle conforms to the principles of ergonomics, making it easier for medical staff to grasp the ultrasound probe and improving the convenience and efficiency of operation.

[0021] 4. Suitable for puncture needles of different diameters

[0022] Since the arc plates are made of elastic material and the distance between the symmetrically arranged arc plates is smaller than the diameter of the puncture needle, the ultrasonic probe of the present invention can be applied to puncture needles of different diameters and has strong versatility.

[0023] The ultrasonic probe of the utility model has broad application prospects and can play an important role in various medical scenarios, improve the accuracy and safety of puncture, and provide better protection for the diagnosis and treatment of patients. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] (1) Working principle of this utility model:

[0030] 1. Principle of overall structural synergy

[0031] The present invention provides an ultrasound probe capable of assisting percutaneous renal puncture, and is primarily composed of a handle, a power cord, a contact head, a slot, a cylinder, and a limiting structure. The handle, serving as the main operating component, connects the power cord and the contact head, transmitting power and enabling contact with the patient. The power cord provides the ultrasound probe with the necessary power to operate, ensuring that it can properly transmit and receive ultrasonic signals. The contact head, in contact with the patient's skin, is responsible for transmitting ultrasonic waves and receiving reflected signals, converting information about the kidneys and surrounding tissues into images for display.

[0032] The groove and cylinder on one side of the handle are key structures for assisted percutaneous renal puncture. The groove provides a mounting position for the cylinder, allowing it to be stably fixed to the handle. The cylinder provides space for the puncture needle, ensuring a tight fit with the ultrasound probe during operation, enabling accurate puncture guidance.

[0033] 2. Structural design principle of the slot

[0034] The slot design makes the cylinder installation more convenient and quick. The opening on one side of the cylinder corresponds to the slot, and the centerline of the slot is set at an acute angle to the centerline of the handle. This makes it easier to use the ultrasound probe to observe the position and insertion angle of the puncture needle, improving the accuracy of the puncture.

[0035] After the puncture is completed, the puncture needle remains stationary, and the ultrasound probe and the handle can be separated along the opening groove and the opening of the cylinder, so that medical staff can proceed to the next step.

[0036] The width and length of the slot are precisely calculated to ensure compatibility with cylinders of varying specifications. The edges of the slot are rounded to prevent scratches on medical staff or patients during operation.

[0037] 3. Working principle of cylinder and limiting structure

[0038] The cylinder, which houses the puncture needle, is carefully designed in size and shape to accommodate needles of varying sizes. It is typically made of high-strength, corrosion-resistant materials, such as medical stainless steel or high-strength plastic, to ensure it will not deform or damage during use.

[0039] The inner wall of the cylinder is smooth, which reduces the friction between the puncture needle and the cylinder, making the puncture needle easy to insert and remove. One end of the cylinder is closed and the other end is open, which facilitates the insertion and fixation of the puncture needle.

[0040] Principle of limiting structure

[0041] The limiting structure consists of multiple curved plates, one end of which is fixedly connected to the inner wall of the cylinder, while the other end is free from contact with the inner wall. This design allows the curved plates to elastically deform when subjected to pressure from the puncture needle, thereby limiting the movement of the puncture needle toward the skin, thereby securing and limiting the puncture needle.

[0042] The multiple curved plates are arranged in at least two rows and arranged in a circular pattern on the inner wall of the cylinder. This arrangement ensures uniform clamping force on the puncture needle in all directions, improving its stability. The symmetrically arranged curved plates are curved in opposite directions. This design allows the puncture needle to be automatically guided to the center of the curved plates after insertion into the cylinder, achieving better fixation.

[0043] However, the position of the curved plate does not block the opening of the cylinder. After the puncture is completed, when the next step is required, the handle and the puncture needle need to be separated. With a little force, the puncture needle can be separated from the handle along the direction of the opening and the opening groove.

[0044] The curved plate is made of an elastic material, such as silicone or rubber, which offers excellent elasticity and wear resistance. This elastic material allows the curved plate to adapt to puncture needles of varying diameters, enhancing the versatility of the ultrasound probe. Furthermore, the elastic material reduces damage to the puncture needle, extending its lifespan.

[0045] In summary, the ultrasound probe capable of assisting percutaneous renal puncture of the present invention achieves accurate fixation and positioning of the puncture needle through reasonable structural design and synergistic effect, thereby improving the accuracy and safety of percutaneous renal puncture and providing medical workers with an efficient and reliable medical device. (II) Specific implementation methods

[0047] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0048] Example:

[0049] 1. Ultrasonic probe structure:

[0050] An ultrasound probe capable of assisting percutaneous renal puncture also comprises a handle, a power cord, and a contact head. One end of the handle is connected to the power cord, and the other end is connected to the contact head.

[0051] An opening groove is provided on one side of the handle, the width of the opening groove is slightly larger than the outer diameter of the cylinder, an opening corresponding to the opening groove is provided on one side of the cylinder, and an angle between the center line of the opening groove and the center line of the handle is an acute angle.

[0052] The cylinder has a semi-closed structure, and its internal limiting structure includes multiple arc-shaped plates. The arc-shaped plates are divided into three rows and are evenly distributed on the inner wall of the cylinder, but do not block the opening of the cylinder. The arc-shaped plates are made of rubber material with good elasticity, and the distance between the symmetrically arranged arc-shaped plates is less than the diameter of the puncture needle.

[0053] 2. Instructions for use:

[0054] During a percutaneous renal puncture, the ultrasound probe's contact tip is placed in contact with the patient's skin and powered on. The doctor uses the ultrasound probe to observe the kidney and surrounding tissues and determine the puncture location.

[0055] When the puncture needle needs to be inserted, it is inserted into the cylinder through the opening. Due to the elastic effect of the curved plate, the puncture needle can move in one direction without shaking left and right. It can also ensure that the ultrasound probe can see the puncture needle during the puncture process, achieving accurate puncture. After the puncture is completed, when the ultrasound probe needs to be removed, because there is no elastic plate at the opening of the cylinder, just hold the puncture needle, hold the handle with a little force, and separate the handle and puncture needle along the direction of the opening and the opening groove to facilitate the next step.

[0056] The sharp angle design between the opening slot and the center line of the handle allows the puncture needle to have a specific tilt angle after insertion, making it easier for doctors to adjust according to the specific conditions of different patients and improving the accuracy and success rate of puncture.

[0057] (3) Application scenario expansion

[0058] In addition to percutaneous renal puncture, this ultrasound probe can also be used in the following medical scenarios:

[0059] 1. Liver puncture

[0060] Liver puncture is often required in the diagnosis and treatment of liver diseases. This ultrasound probe can assist with liver puncture, improving the accuracy and safety of the procedure by securing the needle.

[0061] 2. Breast biopsy

[0062] Mammary puncture is a common method for diagnosing breast diseases. The ultrasonic probe of the present invention can play an important role in mammary puncture. The cylinder and the retaining structure can secure the puncture needle, preventing it from misaligning or shifting, and improving puncture accuracy.

[0063] 3. Thyroid puncture

[0064] Thyroid puncture is crucial for the diagnosis of thyroid disease. This ultrasound probe can assist with thyroid puncture, improving accuracy and safety by securing the needle.

[0065] 4. Lymph node puncture

[0066] Lymph node puncture is a commonly used method in the diagnosis and treatment of lymph node diseases. The ultrasonic probe of the utility model can play a role in lymph node puncture, fix the puncture needle, and improve the accuracy and safety of the puncture.
