Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an ultrasonic puncture device. Background Art

[0002] Ultrasound-guided puncture equipment is equipped with a puncture stand for the ultrasound probe to support and fix the puncture needle, and then puncture is performed under the guidance of the ultrasound instrument. Compared with manual puncture, the puncture process guided by the puncture stand can make the puncture needle move along the guide line set by the ultrasound device, and can be observed by the ultrasound monitor to accurately reach the puncture target.

[0003] In order to fix and guide the puncture needle, the traditional puncture frame mainly includes an ultrasound-guided puncture device disclosed in the announcement number CN116549072B, which adjusts the position of the guide frame and the mounting frame by sliding the movable seat so that the puncture needle faces the puncture area to achieve the purpose of improving the puncture accuracy. However, in the specific use process, when the puncture device disclosed in the patent is used, as the puncture needle approaches the preset puncture area, its structure is not easy to control the puncture depth of the puncture needle, which easily causes the puncture to be too deep or too shallow; at the same time, although the puncture device can adjust the puncture angle of the puncture needle, due to the long needle body of the puncture needle, the device cannot effectively limit the position of the puncture needle during the puncture process, and it is easy for the puncture needle to fail to penetrate the body according to the preset point during puncture, affecting the puncture accuracy.

[0051] Combine the following Figures 1 to 8 The ultrasonic puncture device of the present invention is described.

[0052] Embodiment 1:

[0053] In one embodiment, an ultrasonic puncture device includes an ultrasonic detection probe 1 and an adjustment structure 2 installed at the front end of the ultrasonic detection probe 1; wherein: the ultrasonic detection probe 1 is used for ultrasonic guidance during the ultrasonic puncture process, and a connecting frame 101 is fixedly connected to the surface of the ultrasonic detection probe 1, and a connecting cavity 102 is opened at the other end of the connecting frame 101; the adjustment structure 2 is rotatably installed in the connecting cavity 102, and is used to adjust the puncture route of the puncture needle according to the puncture information fed back by the ultrasonic detection probe 1.

[0054] It should be noted that the ultrasonic detection probe 1 is a prior art and will not be described in detail in this document.

[0055] In a preferred embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the adjustment structure 2 includes two connecting plates 201 installed inside the connecting cavity 102 and symmetrically distributed, a mounting plate 202 is fixedly connected between the two connecting plates 201, both ends of the connecting plate 201 pass through the connecting cavity 102 and extend to the outside of the connecting cavity 102; and a mounting block 203 is fixedly connected to the lower end of the two connecting plates 201, and a limiting rod 204 is fixedly connected to the top of the mounting block 203, which is used to limit and guide the position of the fixed block 2104 through the gap between the two limiting rods 204 during the puncture process, so as to avoid the puncture needle from shifting during the puncture process; a connecting block 205 is also fixedly connected to the surface of the connecting plate 201, and the connecting block 205 is rotatably connected to the inner wall of the connecting cavity 102 through a limiting component 22, and the limiting components 22 are symmetrically arranged on both sides of the surface of the connecting frame 101, so as to limit the inclination angle of the connecting block 205.

[0056] The adjustment structure 2 further comprises an adjustment component 21 disposed between the two connecting plates 201. When in use, the puncture needle is fixed and adjusted by the adjustment component 21 to facilitate puncturing of the patient.

[0057] It should be noted that, in this embodiment, as shown in the attached specification Figure 1 , Figure 2 and Figure 4 It can be seen that, through the arrangement of the two symmetrically arranged connecting plates 201 and the mounting plate 202, the connecting plate 201 and the mounting plate 202 form an adjustment frame, so as to facilitate the installation of the adjustment component 21, the mounting block 203, the limiting rod 204 and the connecting block 205, so that the device is assembled into a whole. Through the arrangement of the limiting component 22, it is convenient to adjust the inclination of the adjustment frame according to the puncture requirements during use, so that the puncture direction can meet the puncture sampling and inspection requirements.

[0058] During specific use, the adjustment component 21 can be set to preset the puncture route and depth, and the laser pen 2106 is used to simulate the puncture route, so that before puncture, the laser line emitted by the laser pen 2106 can be used to cooperate with the ultrasonic detection probe 1 to adjust the puncture route. After the adjustment is completed, the puncture depth can be limited by the positioning seat 2116 during the puncture process, and the puncture speed can be increased at the beginning of the puncture. When approaching the preset puncture position, the puncture speed can be slowed down by changing the knob 2110 to change the rotation efficiency of the screw rod 218, so that the puncture process is more stable, which solves the problem of the existing puncture device that as the puncture needle approaches the preset puncture area, it is not easy to control the puncture depth of the puncture needle, which easily causes the puncture to be too deep or too shallow.

[0059] At the same time, through the setting of two limit rods 204, the fixed block 2104 can be restricted from both sides during use to avoid disturbance of the fixed block 2104, so that the puncture needle can penetrate the patient's body at a vertical downward angle, so that its puncture direction can meet the puncture sampling and inspection requirements.

[0060] Embodiment 2:

[0061] On the basis of the above-mentioned embodiment 1, Figure 3 and Figure 4 As shown, the adjustment component 21 includes a mounting seat 2101 installed between the two connecting plates 201, a slider 2102 is fixedly connected to one side of the mounting seat 2101, the other end of the slider 2102 passes through the mounting plate 202 and matches with the guide groove provided on the mounting plate 202, and the movement of the slider 2102 is guided by the guide groove; a rotating block 2103 is also rotatably connected to the inner side of the mounting seat 2101, and two fixed blocks 2104 are fixedly connected to the surface of the rotating block 2103, and the two fixed blocks The angle between 2104 is 90°, and a laser pen 2106 is arranged on the surface of one of the fixed blocks 2104, and a mounting hole is opened on the surface of the other fixed block 2104 for use with a puncture needle, and a fastening screw 2105 for fastening the puncture needle is arranged on the surface of the fixed block 2104. When in use, the puncture needle can pass through the mounting hole, and the position of the puncture needle can be limited and fixed by the fastening screw 2105; during puncture, the limiting rod 204 can act on both sides of the fixed block 2104 to limit the fixed block 2104.

[0062] It should be noted that, in this embodiment, Figure 3 The state shown is the state when the puncture needle is not installed. During puncture, the rotating block 2103 needs to be rotated so that the fixed block 2104 on which the puncture needle is installed is between the extension lines of the two limit rods 204. In specific use: before use, according to the detection result of the ultrasonic detection probe 1, the puncture route is adjusted by starting the laser pen 2106. The laser line emitted by the laser pen 2106 is used to simulate the puncture route during the adjustment process. By rotating the connecting block 205, the connecting plate 201 can be driven to rotate to adjust the overall tilt angle of the laser line. After the adjustment is completed, the fixed block 2104 can be driven to rotate with the rotating block 2103 as the axis. After the puncture tilt angle is adjusted, the fixed block 2104 with the puncture needle installed can be moved between the two connecting plates 201 by rotating the fixed block 2104, so that the route positioned by the laser pen 2106 is used to drive the mounting seat 2101 to move along the preset puncture route through the moving slider 2102, which can effectively improve the stability and accuracy of the puncture process.

[0063] In a preferred embodiment, Figure 2 , Figure 4 and Figure 5 As shown, a support plate 2107 is fixedly connected to one side of the mounting plate 202, a screw rod 2108 is arranged at the bottom of the support plate 2107, the other end of the screw rod 2108 is rotatably connected to the surface of the mounting plate 202, and the slider 2102 is threadedly connected to the screw rod 2108, and two symmetrically distributed guide rods 2109 are fixedly connected to the bottom of the support plate 2107, and the lower end of the guide rod 2109 passes through the slider 2102 and is fixedly connected to the surface of the mounting plate 202.

[0064] Two knobs 2110 are fixedly connected to the top of the support plate 2107 , wherein the lower end of one of the knobs 2110 passes through the support plate 2107 and is fixedly connected to the second gear 2112 , and the upper end of the screw rod 2108 is fixedly connected to the bottom of the second gear 2112 .

[0065] A first gear 2111 rotatably connected to the inner wall of the support plate 2107 is fixedly connected to the bottom of the other knob 2110 . The first gear 2111 is meshedly connected to the second gear 2112 . The circumference ratio of the first gear 2111 to the second gear 2112 is 3:1.

[0066] It should be noted that, in this embodiment, through the above-mentioned structure, when in use, the knob 2110 connected to the first gear 2111 can be rotated to drive the first gear 2111 to rotate the second gear 2112 meshing therewith, thereby driving the screw rod 2108 to rotate, so that the slider 2102 moves downward along the surface of the screw rod 2108, and the position of the mounting seat 2101 is adjusted, so that the puncture needle can be driven into the patient's body by the mounting seat 2101. At the same time, since the circumference ratio of the first gear 2111 to the second gear 2112 is 3:1, the second gear 2112 can be driven to rotate faster when the knob 2110 connected thereto is rotated, so that the slider 2102 can be driven to move faster through the screw rod 2108, that is, the puncture needle can be inserted into the patient's body at a faster speed on the basis of ensuring stability.

[0067] In a preferred embodiment, Figure 4 , Figure 5 and Figure 6 As shown, the surface of the screw rod 2108 is slidably connected with a positioning seat 2116, the top of the positioning seat 2116 is provided with a groove, the top of the positioning seat 2116 is provided with a trigger plate 2114 matching the groove, the bottom of the trigger plate 2114 is fixedly connected with evenly distributed adjustment rods 2113, and the lower end of the adjustment rod 2113 passes through the positioning seat 2116.

[0068] A first spring 2117 is fixedly connected to the surface of the adjusting rod 2113 , and the other end of the first spring 2117 is fixedly connected to the bottom of the positioning seat 2116 .

[0069] The surface of the positioning seat 2116 is provided with two evenly distributed limiting bolts 2115, and the surface of the mounting plate 202 is provided with evenly distributed limiting screw holes 2118. The other end of the limiting bolt 2115 passes through the positioning seat 2116 and is threadedly connected to the inner wall of the adjacent limiting screw hole 2118.

[0070] It should be noted that in this embodiment, through the setting of the above-mentioned structure, when in use, before puncture, the positioning seat 2116 is moved to slide along the surface of the screw rod 2108 to move it to the required depth for puncture. The position of the positioning seat 2116 can be limited by passing the limiting bolt 2115 through the positioning seat 2116 and threading it with the adjacent limiting screw hole 2118. During the adjustment process, as the slider 2102 moves downward, it can contact the top of the trigger plate 2114. In this process, the trigger plate 2114 can be driven to make the adjustment rod 2113 gradually pass through the positioning seat 2116 and stretch the first spring 2117. As the slider 2102 gradually approaches the positioning seat 2116, the pressure required to stretch the first spring 2117 is greater, so that the resistance generated by rotating the knob 2110 is greater. As the resistance increases, the user is prompted that the preset puncture position is about to be reached. At this time, the user can replace the knob 2110 to directly rotate the second gear 2112, thereby slowing down the rotation speed of the screw rod 2108, so as to control the puncture speed of the puncture needle and improve stability. The puncture speed can be increased in the early stage of puncture. When approaching the preset puncture position, the puncture speed can be slowed down by changing the rotation efficiency of the screw rod 2108 by replacing the knob 2110, so that the puncture process is more stable.

[0071] It should be noted that, in this embodiment, by setting the structure of the above-mentioned adjustment component 21, it is possible to form a mechanism for achieving accurate and constant-depth puncture during the puncture process, thereby performing accurate and constant-depth puncture on the patient. The specific use process includes: before puncture, first, by moving the positioning seat 2116 to slide along the surface of the screw rod 2108, when it moves to the required puncture depth, the limiting bolt 2115 is passed through the positioning seat 2116 and is threadedly connected with the adjacent limiting screw hole 2118, so that the position of the positioning seat 2116 can be limited; after the position of the positioning seat 2116 is limited, by rotating the knob 2110 connected to the first gear 2111, the first gear 2111 can be driven to rotate the second gear 2112 meshing therewith, thereby driving the screw rod 2108 to rotate, so that the slider 2102 moves downward along the surface of the screw rod 2108. Since the circumference ratio of the first gear 2111 to the second gear 2112 is 3:1, when the knob 2110 connected thereto is rotated, the second gear 2112 can be driven to rotate faster, thereby increasing the speed at which the slider 2102 is driven by the screw rod 2108 to move. The speed is faster; as the slider 2102 moves downward, it can contact the top of the trigger plate 2114. In this process, the trigger plate 2114 can be driven to make the adjustment rod 2113 gradually pass through the positioning seat 2116 and stretch the first spring 2117. As the slider 2102 gradually approaches the positioning seat 2116, the pressure required to stretch the first spring 2117 is greater, so that the resistance generated by rotating the knob 2110 is greater. As the resistance increases, it can prompt the user that the preset puncture position is about to be reached. At this time, the user can replace the knob 2110 to directly rotate the second gear 2112, thereby slowing down the rotation speed of the screw rod 2108, so as to control the puncture speed of the puncture needle and improve stability. The puncture speed can be increased in the early stage of puncture. When approaching the preset puncture position, the puncture speed can be slowed down by changing the rotation efficiency of the screw rod 2108 by replacing the knob 2110, so that the puncture is more stable.

[0072] Embodiment 3:

[0073] Based on the above embodiments, Figure 1 , Figure 2 and Figure 8As shown, the limit assembly 22 includes a rotating shaft 2201 fixedly connected to the end surface of one of the connecting blocks 205, the other end of the rotating shaft 2201 passes through the connecting frame 101 and is provided with a pull plate 2206, the surface of the connecting frame 101 is fixedly connected with a connecting ring 2202 coaxially arranged with the rotating shaft 2201, and the surface of the connecting ring 2202 is provided with evenly distributed card grooves 2207; the surface of the pull plate 2206 is fixedly connected with a connecting rod 2205, the other end of the connecting rod 2205 is slidably connected to the inner wall of the rotating shaft 2201, and a second spring 2203 is fixedly connected between the surface of the connecting rod 2205 and the inner wall of the rotating shaft 2201.

[0074] A clamping block 2204 is fixedly connected to the surface of the pull plate 2206 , and the clamping block 2204 matches the clamping slot 2207 .

[0075] It should be noted that in the present embodiment, when in use, by pulling the pull plate 2206, the connecting rod 2205 is compressed and the second spring 2203 is stretched, and at this time, the card block 2204 can be separated from the card slot 2207, so that the connecting block 205 can be driven to rotate through the rotating shaft 2201 to achieve the effect of adjusting the rotation angle of the connecting plate 201, and after adjusting to the desired rotation angle, the pull plate 2206 is released and the pull plate 2206 can be reset under the action of the second spring 2203, thereby driving the card block 2204 to be inserted into the adjacent card slot 2207, so as to achieve the effect of limiting the position of the rotating shaft 2201, and the preset inclination angle can be maintained during the puncture process for easy puncture.

[0076] The working and use principles of the ultrasonic puncture device of the present invention include:

[0077] Step 1: According to the detection result of the ultrasonic detection probe 1, the puncture line angle is adjusted by starting the laser pen 2106, and the inclination angle of the adjusted connecting plate 201 is limited by the limiting component 22;

[0078] Step 2: After the adjustment is completed, the fixed block 2104 can be driven to rotate through the rotating block 2103 by toggling it. In this process, the fixed block 2104 with the puncture needle installed is moved between the two connecting plates 201. At this time, the mounting seat 2101 can be driven to move along the preset puncture route by moving the slider 2102, thereby improving the stability during the puncture process;

[0079] Step 3: During the puncture process, the position of the fixing block 2104 can be limited by the gap between the two limiting rods 204 to prevent the puncture needle from shifting during the puncture process;

[0080] Step 4: By setting the adjustment component 21, the puncture speed can be increased in the early stage of puncture. When approaching the preset puncture position, the puncture speed can be slowed down by changing the knob 2110 to change the rotation efficiency of the screw rod 2108, so that the puncture process is more stable.

[0081] The technical features of the above-described embodiments may be arbitrarily combined.
