Description

Ultrasonic puncture kit and ultrasonic puncture display kit

Technical Field

The invention relates to the field of ultrasonic waves, in particular to an ultrasonic puncture kit and an ultrasonic puncture display kit.

Background

Today, the way to probe the inside of a body cavity and extract the tissue and body fluids inside the body cavity is commonly referred to as fine needle aspiration biopsy under ultrasound endoscope guidance. In this method, the inside of the body cavity is observed with an ultrasonic probe to confirm the target position, and after confirming the position, the body cavity is penetrated with a puncture needle and the target is punctured to perform the extraction operation.

The combination of the ultrasonic probe and the puncture needle is also applied to the egg taking action of animals, however, the existing puncture needle for taking eggs is expensive and is usually reused. However, the puncture needle is easy to remain body fluid after multiple sampling and is not easy to clean, so that bacteria are easy to grow on the puncture needle. When the sterile needle is not completely cleaned and reused for aspiration, the recipient of the aspiration will be exposed to the risk of bacterial infection. In addition, the puncture needle can be worn or deformed under repeated use, so that the difficulty of invasive sampling (ovum) is increased.

Therefore, it is necessary to design a new ultrasonic puncture kit and an ultrasonic puncture display kit to overcome the above-mentioned drawbacks.

Certain terms are used throughout the description and claims to refer to particular components. It will be appreciated by those of ordinary skill in the art that manufacturers may refer to a component by different names. The description and claims do not take the form of an element differentiated by name, but rather by functional differences. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to.

Referring to fig. 1 to 3, the ultrasonic puncture display kit 100 of the present invention includes an ultrasonic module 110 and a puncture needle set 120. The puncture needle set 120 is suitable for taking an egg and sampling or extracting body fluid from a specific portion, and the ultrasonic module 110 is used for sensing the relative position of the puncture needle set 120 and a subject and outputting dynamic images at the same time, so as to facilitate a user to align the puncture needle set 120 with a subject 200, wherein the subject 200 is an ovum or an organ, for example.

Referring to fig. 1 to 5, the ultrasonic module 110 includes a main body 111, a sensing probe 112, a positioning sleeve 113, a processor 114, and a display 115.

The main body 111 is used for being held by a user. The sensing probe 112 is disposed at one end of the main body 111 and is capable of emitting at least one ultrasonic wave W1 or receiving an ultrasonic echo W2. The positioning sleeve 113 is connected to one side of the main body 111 and is dislocated from the sensing probe 112, so that the positioning sleeve 113 avoids the propagation path of the ultrasonic wave W1 or the ultrasonic echo W2 of the sensing probe 112, and avoids interference images. The sensing probe 112 is electrically connected to the processor 114, and the processor 114 is configured to at least transmit a command to drive the sensing probe 112 to emit an ultrasonic wave W1 signal or analyze an ultrasonic echo W2 signal received by the sensing probe 112. The processor 114 is electrically connected to the display 115, and the display 115 is used for outputting images.

Referring to fig. 3 in detail, when the ultrasonic wave W1 hits various tissues in the body and is reflected back to the sensing probe 112, the sensing probe 112 receives different ultrasonic echo W2 signals because the components and densities of various muscles or organs in the body are different and the transmission of the ultrasonic wave W1 is affected to different degrees, and the different ultrasonic echo W2 signals can be converted into black-and-white images and displayed on the display 115 after being analyzed by the processor 114, and the respective tissues of the subject can be distinguished according to the difference of the image depth.

Fig. 6 is an enlarged schematic view of a portion of the stem of the ultrasonic penetration assembly of fig. 1. Fig. 7 is a perspective view of the stem of fig. 6 in another direction. Fig. 8 is a perspective view of the tubing handle of fig. 7 in combination with a needle and infusion tube. Fig. 9 is a schematic cross-sectional view of the tubing holder of fig. 8 holding an infusion tube.

Referring to fig. 6-8, a needle set 120 is removably disposed within the positioning sleeve 113 and includes a stem 121, a needle 122, and an infusion tube 123.

The stem 121 has a locking groove G1 and a linear groove G2, and the locking groove G1 is formed at one end of the stem 121. The linear grooves G2 are formed through the other end of the stem 121 and extend toward the catching groove G1 to communicate with each other, and the linear grooves G2 are semicircular or semi-elliptical in cross section in a radial direction (i.e., RD direction as shown in fig. 6). The needle 122 is detachably disposed in the card slot G1. The infusion tube 123 is disposed in the linear groove G2 and is in communication with the needle 122, i.e., the extract of the needle 122 from the target 200 flows into the infusion tube 123 (see fig. 3).

Further, referring to fig. 9, an inner side IS of the linear groove G2 IS adapted to hold the infusion tube 123. The linear groove G2 interferes with the infusion tube 123 by pressing, thereby fixing the infusion tube 123 in the tube grip 121.

Referring to fig. 1 and 3, when the puncture needle set 120 is disposed in the positioning sleeve 113, that is, the user punctures the puncture needle set 120 in the positioning sleeve 113 and moves toward the sensing probe 112, finally, the needle 122 is positioned on the positioning sleeve 113 and extends and protrudes to one side of the sensing probe 112 and the display 115 presents a picture with the needle 122, which means that the needle 122 partially overlaps the sensing probe 112 and is on the transmission path of the ultrasonic wave W1.

Referring to fig. 3, the sensing probe 112 is adapted to generate an ultrasonic wave W1 toward the needle 122, and the ultrasonic wave W1 will generate an ultrasonic echo W2 when contacting the needle 122, and the sensing probe 112 also receives the reflected ultrasonic echo W2 to detect the position of the needle 122 relative to the sensing probe 112 or the position of the needle 122 within the subject. Further, needle 122 has penetrated the subject and is aligned with target 200 as shown in fig. 3.

Referring to fig. 1 and 4, in addition to some embodiments, the display 115 presents a view of the target 200 and needle 122 within the target, in other embodiments, since the ultrasound puncture display kit 100 is adapted for a known size of a male needle 122 and the positioning sleeve 113 has been positioned on one side of the sensing probe 112. Therefore, the processor 114 can directly display a screen with the simulated needle 122 on the display 115 according to the built-in data, and the user first aligns the simulated needle 122 with the target 200, and then inserts the actual needle 122 into the positioning sleeve 113.

In short, since the size of the needle 122 and the position of the positioning sleeve 113 are fixed in this embodiment, the image of the simulated needle 122 can be aligned in advance. This is suitable for the situation that the actual needle 122 is not inserted into the positioning sleeve 113, the simulated needle 122 image is utilized to align with the target 200, and then the puncture needle set 120 is inserted into the positioning sleeve 113 to extract the sample from the target 200, or the situation that the ultrasonic image is unclear, the simulated needle 122 image is utilized to learn the actual needle 122 position.

Referring to fig. 1 and 6, the stem 121 has an elastic hole EH, which communicates with and is parallel to the linear groove G2, and the stem 121 is capable of being deformed in the radial RD direction to expand the elastic hole EH, which is advantageous for accommodating and holding the infusion tube 123. In addition, the elastic hole EH of the pipe handle 121 provides an elastic deformation range, so that the pipe handle 121 can be elastically deformed along with the inner diameter dimension of the positioning sleeve 113 in the process of penetrating into the positioning sleeve 113, thereby achieving the effects of smooth movement and depth positioning.

Referring to fig. 1, 6 to 8, the puncture needle set 120 is movably disposed in the positioning sleeve 113. In detail, the needle 122 has a tube 1221 and a needle 1222. The tube 1221 is detachably engaged with the engagement groove G1 of the stem 121, and the needle 1222 is disposed in the tube 1221 and protrudes from the stem 121. The infusion tube 123 has a joint 1231, and a tube portion 1221 that is engaged with the engagement groove G1 of the tube handle 121 and contacts the needle 122, and the joint 1231 and the tube portion 1221 communicate with each other.

Referring to fig. 6 to 8, a trigger 1211 is formed around an end of the stem 121 remote from the needle 122. The trigger 1211 is adapted to withdraw the lancet set 120 from the positioning sleeve 113 to disengage the sensing probe 112 after sampling is completed.

Further, the stem 121 is made of an elastic material and has elastic deformation capability. In addition, the outer diameter of the stem 121 may be varied to increase or decrease the amount of interference penetrating the positioning sleeve 113 depending on the size to vary the exit speed of the needle 122. For example, increasing the outer diameter of the stem 121 increases the amount of interference of the stem 121 during penetration into the positioning sleeve 113, thereby slowing the movement of the stem 121 within the positioning sleeve 113, which slows the exit of the needle 122 from the positioning sleeve 113, avoiding puncture of the user. If the outer diameter of the stem 121 is reduced, the interference of the stem 121 during the process of penetrating into the positioning sleeve 113 is reduced, thereby increasing the moving speed of the stem 121 in the positioning sleeve 113, so as to increase the needle outlet speed of the needle 122 protruding out of the positioning sleeve 113, and achieve the purpose of rapid sampling.

In other embodiments, the outside diameter of the stem 121 may vary at any location along the straight line, such as increasing outside diameter toward the needle 122, decreasing outside diameter toward the needle 122, or increasing outside diameter toward the needle 122.

Still further, the stem 121 may be a complete round tube or an incomplete round tube (e.g., a half-cut round tube). When the tube handle 121 is a complete round tube, the clamping groove G1 and the linear groove G2 in the tube handle 121 are completely wrapped by the peripheral wall (at this time, the linear groove G2 may be referred to as a through groove), the needle 122 and the infusion tube 123 may be plugged in from the pulling portion 1211, and the needle 122 may be pulled out from the other end by an external force, so that the needle 122 and the infusion tube 123 may be disposed in the tube handle. Or the tube handle 121 further comprises a pivot to open and close the two half-cut round tubes, when the two half-cut round tubes are opened, the needle 122 and the infusion tube 123 are arranged in the tube handle 121 from the lateral direction of the tube handle 121, and then the puncture needle set 120 is completed after the two half-cut round tubes are closed; moreover, when the tube handle 121 is a complete round tube, the elastic hole EH on the tube handle 121 may have two opposite positions, so that the tube handle 121 is easier to deform along the radial direction RD to prop open the elastic hole EH, which is more beneficial to accommodating and clamping the infusion tube 123. When the stem 121 is a non-complete round tube, the shapes of the clamping groove G1, the tube 1221 and the joint 1231 are not completely identical, the tube 1221 and the joint 1231 are plugged into the clamping groove G1 from the side direction of the stem 121 by using an external force, and after the combination, the needle 122 and the infusion tube 123 can be fixed due to the stress generated by the non-identical shapes of the clamping groove G1, the tube 1221 and the joint 1231, thus completing the puncture needle set 120. Alternatively, the tube handle 121 is a part of a non-complete circular tube (for example, C-shaped, or a section with a central angle larger than 180 °) cut at the tube surface, the tube 1221 and the joint 1231 can be plugged into the needle 122 and the tube handle 121 of the infusion tube 123 from the notch by using an external force, and the needle 122 and the infusion tube 123 are fixed by the clamping force of the non-complete circular tube, so as to complete the puncture needle set 120.

In summary, the ultrasonic puncture kit of the present invention is suitable for the conventional needle and infusion tube, and thus has the characteristic of easy disassembly and replacement, and after each sampling and taking an egg or extracting a body fluid, the needle and infusion tube contaminated by the body fluid can be replaced, so that the infection of a receptor caused by repeated use can be avoided, and the problems that different manufacturers only provide puncture needle products suitable for the needle and infusion tube with specific specifications, and users cannot conveniently and at any time obtain the replaceable needle and infusion tube, which causes operation delay or high cost and the like can be avoided. Compared with the existing puncture needle, the ultrasonic puncture kit provided by the invention has the advantages that the defects that the needle head and the infusion tube are not easy to clean, body fluid remains and the like are overcome, and the abrasion or deformation caused by repeated use of the existing puncture needle can be avoided.

Furthermore, the ultrasonic puncture display kit of the invention is combined with the display and is suitable for transmitting the ultrasonic signals received by the sensing probe to the display, thereby presenting a real puncture picture with at least a needle head or a simulated puncture picture with a simulated needle head.

The invention has been described with respect to the above-described embodiments, however, the above-described embodiments are merely examples of practicing the invention. It should be noted that the disclosed embodiments do not limit the scope of the invention.
