Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a light beam guiding device and a puncture device. Background Art

[0002] With the advancement of science and technology, ultrasound probes have become a common diagnostic technology in the medical field. Early use of ultrasound probes was primarily for physical examinations, but later developments have led to a more significant role in clinical surgery and other settings. In clinical practice, ultrasound probes are essential for puncture sampling. However, accurately locating blood vessels within the skin is not a simple task, necessitating the use of auxiliary equipment.

[0003] Currently, the most common approach is to use lasers for guided puncture. However, due to the smooth surface of the probe, the laser and probe are difficult to securely connect. This typically requires at least two doctors: one to use the probe and laser while the other performs the puncture. This not only wastes manpower and resources, but also prevents the probe and laser from remaining relatively stationary, making guidance errors more likely. Utility Model Content

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

[0035] See Figure 1 and Figure 6 The present application provides a beam guiding device for cooperating with the probe 200 for ultrasonic detection to guide the puncture position of the beam guide 300, mainly including a bracket 100 and a connecting portion 120 on the bracket 100. The bracket 100 has a first space 110 for accommodating the probe 200. The connecting portion 120 is located on the outer side of the bracket 100 and is fixedly connected to the bracket 100. The first space 110 has an opening that can be adjusted in size. Specifically, the size of the opening depends on the state of the bracket 100. The bracket 100 has a snap-on state and an open state: in the snap-on state, the opening is configured to snap on or against the outer surface of the probe 200 so that the first space 110 accommodates the probe 200; in the open state, the opening is configured to be greater than the maximum distance of the probe 200 along the direction in which the opening extends, so that the bracket 100 is detached from the probe 200.

[0036] In the above embodiment, the first space 110 can completely surround the probe 200 along the circumference, for example Figure 1In the structural diagram in FIG, the side of the accommodation space is continuous, or there is a small opening, but the structure of the probe 200 will not leak out of the first space 110. In other embodiments, the first space 110 may only accommodate about half of the main structure of the probe 200, such as a clip with elastic force. The bracket 100 may be a C-shaped clip with elastic material, and the clip has two ends. The two ends and the middle position of the clip enclose the accommodation space. In the static state, the distance between the two ends is smaller than the distance between the two sides of the probe to be clamped. When it is needed, the two ends of the bracket 100 use elastic force to clamp the two outer sides of the probe 200, and the elastic force is used to ensure the stability of the clip. Then, the beam guide 300 is installed on the clip, thereby achieving relative stillness of the beam guide 300 and the probe 200.

[0037] The beam guiding device provided in the present application fixedly connects the probe 200 and the laser and keeps them relatively stationary, so that only one doctor is required to complete the puncture operation, which not only saves manpower and material resources but also improves the accuracy of the puncture.

[0038] Preferred, Participate Figure 2 and Figure 3 In one embodiment, the bracket 100 includes a mounting portion 130 and a fixing portion 140. The connecting portion 120 is located on the outer surface of the mounting portion 130 and is fixedly connected to the mounting portion 130. In the engaged state, the ends of the fixing portion 140 are fixedly connected to the ends of the mounting portion 130 to form the first space 110, and the opening is engaged. In the open state, at least one end of the fixing portion 140 is disconnected from the mounting portion 130, and the opening is open.

[0039] In the above embodiment, the length of the mounting portion 130 along the outer side surface of the probe 200 is approximately two-thirds of the probe 200, and the fixing portion 140 is one-third. In this way, the mounting portion 130 plays a main role, and the fixing portion 140 plays a fixing role. The mounting structure with different lengths is more stable and not easy to rotate during the use of the probe 200.

[0040] The fixing portion 140 and the mounting portion 130 provided in this application are detachable at both ends, thereby facilitating disassembly and disinfection, ensuring medical cleanliness requirements. During installation, the fixing portion 140 and the mounting portion 130 can be connected at one end first, and then connected at the other end when the probe 200 is mounted.

[0041] See Figure 2 and Figure 3In one embodiment, the connection structure provided by the present application is: a first axial hole 131 is provided at one end of the mounting portion 130, and a protrusion 132 is provided at the other end; a second axial hole 141 is provided at one end of the fixing portion 140, and an elastic buckle 142 is provided at the other end; the elastic buckle 142 is engaged with the protrusion 132.

[0042] In other embodiments, the fixing portion 140 may have a first axial hole 131 at one end and a protrusion 132 at the other end, and the mounting portion 130 may have a second axial hole 141 at one end and an elastic buckle 142 at the other end, and the elastic buckle 142 may be engaged with the protrusion 132.

[0043] The first shaft hole 131 and the second shaft hole 141 can be aligned, and relative rotation can be achieved by inserting a pin. The elastic buckle 142 can be engaged with the protrusion 132. These two structures are relatively common connection structures.

[0044] In other embodiments, there are many ways to connect, such as using bonding, which only requires putting it on and then bonding it. This application uses the elastic buckle 142 and the protrusion 132, or bonding, which is faster to connect and takes up less space.

[0045] Preferably, in one embodiment, the inner surfaces of the mounting portion 130 and the fixing portion 140 are configured to fit the outer surface of the probe 200, and the inner wall of the mounting portion 130 and / or the fixing portion 140 is provided with an elastic object 150, which is configured to be able to resist and deform against the outer surface of the probe 200 in the buckled state to generate a rebound force.

[0046] Generally, the outer surface of the probe 200 is an irregular shape, mainly for the convenience of holding. When the mounting part 130 and the fixing part 140 are put on the probe 200, in order to avoid sliding due to low friction, the present application provides an elastic object 150 on the inner surface of the mounting part 130 and the fixing part 140. In this way, the elastic object 150 will be deformed by the pressure of the outer surface of the probe 200 and the inner surface of the bracket 100. In this way, the elastic object 150 will generate a thrust to push the bracket 100 and the probe 200 away from each other, and increase the static friction, so that the bracket 100 and the probe 200 can remain relatively still.

[0047] Preferably, in one embodiment, at least two connecting portions 120 are provided, and the two connecting portions 120 are spaced apart along the outer circumference of the cross-section of the bracket 100. When the bracket 100 is fixedly connected to the probe 200, at least one connecting portion 120 is located within the detection plane of the probe 200, and at least one is located outside the detection plane of the probe 200.

[0048] The above embodiments involve in-plane puncture and out-of-plane puncture. In-plane puncture means that when the probe 200 performs ultrasonic detection, a surface is formed. When puncturing within this surface, the needle body of the puncture needle can be seen on the ultrasound display screen. This is in-plane puncture. The purpose of out-of-plane puncture is to make the puncture needle pass through this ultrasonic detection surface. The bracket 100 provided in this application is provided with two connecting parts 120, and the two connecting parts 120 are one in-plane and the other out-of-plane. In this way, the doctor does not need to replace the guiding device. He only needs to replace the connecting part 120 of the beam guide 300 to achieve the switching between in-plane puncture and out-of-plane puncture. Therefore, the beam guiding device provided in this application greatly improves the efficiency of medical diagnosis and has better applicability.

[0049] Preferably, see Figure 2 In one embodiment, the connecting portion 120 is provided with a second space 121 , and the interior of the second space 121 is used for clamping the light beam guide 300 .

[0050] Typically, the beam guide 300 is a laser, which is usually cylindrical and smooth in appearance and difficult to fix. The present application uses the second space 121 to place the beam guide 300 without worrying about the beam guide 300 being separated from the connection part 120.

[0051] Preferably, see Figure 2 In one embodiment, the inner wall of the connecting portion 120 is provided with side ribs 122. The extension direction of the side ribs 122 can be the axial direction of the second space 121, or can be arranged in a surrounding manner. The side ribs 122 can be a hard material or a soft material such as elastic glue, both of which can increase the friction between the connecting portion 120 and the beam guide 300, making the connection state more stable.

[0052] Preferably, see Figure 1 In one embodiment, a conversion lens 160 is further included. A snap-in groove 123 is provided at one end of the second space 121. The conversion lens 160 is fixedly installed in the snap-in groove 123. The conversion lens 160 is configured to transform the shape of the light beam emitted by the light beam guide 300.

[0053] Generally, for greater applicability, the beam guide 300 is usually a point light source laser pen that is more common on the market. Therefore, in order to convert the point light beam into a linear light beam, the present application provides a conversion lens 160. The conversion lens 160 is fixed at one end of the second space 121 in the connecting part 120, so that the light beam emitted by the laser pen passes through the conversion lens 160 to complete the shape transformation.

[0054] See Figure 4 and Figure 5In one embodiment, a limiting member 133 is provided on the outer surface of the bracket 100, and the connecting portion 120 is provided with a clamping portion 124 that cooperates with the limiting member 133, and the connecting portion 120 and the bracket 100 are detachably connected.

[0055] The connecting part 120 and the main body of the bracket 100 can be an integral structure or a detachable relationship. In this embodiment, the limiting member 133 is a protrusion and the clamping part 124 is a notch. The connecting part 120 can be slid relative to the bracket 100 through the slide rail, and then the protrusion and the notch are limited and matched to achieve a fixed connection.

[0056] participate Figure 6 The present application also provides a puncture device, including the beam guiding device provided in any one of the above embodiments, and also including a probe 200. The beam guiding equipment is detachably connected to the probe 200. The inner surface of the bracket 100 in the beam guiding device is in contact with the outer surface of the probe 200. The beam guide 300 can be fixedly connected to the connecting part 120. The beam guide 300 is configured to emit a light beam in the detection direction of the probe 200.

[0057] The puncture device provided in the present application can facilitate doctors to perform puncture operations without the need for two doctors to operate together, saving manpower and material resources, and avoiding the risk of errors caused by the failure of the beam guide 300 and the probe 200 to remain relatively still at all times.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
