[0027] To further illustrate each embodiment, the present invention provides drawings. These drawings are a part of the disclosure of the present invention, mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0029] Refer to Figures 1 to 4As shown in the figure, this embodiment provides an electric target aiming device for precise transperineal prostate puncture (hereinafter simply referred to as the electric target aiming device). The electric target aiming device includes a target plate 2 for positioning and guiding the puncture needle, and further includes a card electric cylinder 3 for driving the target plate 2 to perform quantitative incremental motion in the vertical direction. An installation base 4 is provided between the lifting part of the target plate 2 and the card electric cylinder 3. The installation base 4 is fixed to the lifting part of the card electric cylinder 3. The fixed part of the card electric cylinder 3 is used to fix the ultrasonic probe 1. The target plate 2 has an installation bump 21. As Figure 5 and Figure 6 shown, the installation base 4 has an installation groove 41 that cooperates with the installation bump 21. The installation bump 21 is slidably assembled in the installation groove 41. As Figure 7 shown, the installation bump 21 facing the left side of the installation groove 41 is provided with an elastic arm 211 that protrudes and extends outward. The groove wall of the installation groove 41 is provided with a first limiting part, and the elastic arm 211 is provided with a second limiting part that cooperates with the first limiting part. Relying on the elastic force of the elastic arm 211 itself, the first limiting part and the second limiting part limit each other, so that the target plate 2 can be replaceably fixed on the installation base 4.

[0030] In this embodiment, as Figure 1 shown, the card electric cylinder 3 belongs to the prior art and includes a cooperating slide table 31 and a fixed guide rail 32. The slide table 31 is restricted by the fixed guide rail 32, and the slide table 31 can slide quantitatively on the fixed guide rail 32. The slide table 31 is the lifting part of the card electric cylinder 3, and the fixed guide rail 32 is the fixed part of the card electric cylinder 3. Specifically, the single incremental motion distance of the lifting part of the card electric cylinder 3 is 0.1 mm, so as to meet the requirements for selecting a more accurate puncture position and ensure the accuracy and reliability of the percutaneous biopsy technique.

[0031] As Figure 7 shown, the target plate 2 has a plurality of equally spaced positioning and guiding holes 22 for cooperating with the puncture needle. The extending direction of the positioning and guiding holes 22 is perpendicular to the incremental motion track of the target plate 2, that is, the puncture direction of the puncture needle is perpendicular to the moving direction of the slide table 31, so as to avoid large errors or deviations in the puncture position.

[0032] When the electric target aiming device is in use and it is necessary to move the puncture position of the puncture needle upward by 0.1 mm as a whole, only need to drive the card electric cylinder 3 to perform one incremental motion; and so on. If it is necessary to move the puncture position upward by 0.2 mm as a whole, just drive the card electric cylinder 3 to perform two incremental motions, and there is no need to adjust the corresponding height of the target plate 2 against the scale line. Such operation is convenient.

[0033] As Figure 5 and Figure 6As shown, a positioning hole 411 is provided on the groove wall of the installation groove 41 of the mounting base 4, and a limiting protrusion 212 that cooperates with the positioning hole 411 is provided on the elastic arm 211 of the mounting protrusion 21 of the target plate 2. The positioning hole 411 is the first limiting portion, and the limiting protrusion 212 of the elastic arm 211 is the second limiting portion. Moreover, the limiting protrusion 212 is located at the bottom of the elastic arm 211, and the corresponding positioning hole 411 is also located on the lower groove wall of the installation groove 41.

[0034] As Figure 2 and Figure 3 shown, when the target plate 2 needs to be installed on the mounting base 4, the mounting protrusion 21 of the target plate 2 is pushed into the installation groove 41 of the mounting base 4 by an external force. The elastic arm 211 on the mounting protrusion 21 receives the reaction force of the mounting base 4, causing the elastic arm 211 to undergo a small upward bending deformation, so that the limiting protrusion 212 is no longer blocked by the lower groove wall of the installation groove 41 and smoothly slides into the positioning hole 411. After that, without external force, the elastic arm 211 abuts against the lower groove wall of the installation groove 41 by its own elastic force, so as to simultaneously realize the embedding of the limiting protrusion 212 into the positioning hole 411, thereby completing the fixation of the target plate 2 on the mounting base 4.

[0035] When the target plate 2 needs to be removed or replaced, the target plate 2 is pulled out of the mounting base 4 by an external force, overcoming the elastic force limitation of the elastic arm 211 itself, so that the elastic arm 211 undergoes a small upward bending deformation again, causing the limiting protrusion 212 to disengage from the positioning hole 411. After that, the mounting protrusion 21 of the target plate 2 is pulled out of the installation groove 41, facilitating the quick removal or disassembly of the target plate 2. In this way, the target plate 2 can be quickly plugged and unplugged, and there is no need to fasten it by screws or other fastening methods. At the same time, no additional auxiliary tools are required for disassembly and assembly, realizing simple and convenient installation operations.

[0036] Through the card electric cylinder 3, the target plate 2 is driven to achieve quantitative jogging in the vertical direction, thereby realizing the adjustment of the target plate 2 at different puncture heights. At the same time, the manual adjustment method is avoided to achieve more convenient puncture operations. Moreover, through the cooperation of the elastic arm 211, the first limiting portion and the second limiting portion, the target plate 2 can be quickly and conveniently replaced, facilitating the replacement of different models of the target plate 2.

[0037] Of course, in other embodiments, the target plate 2 has an installation groove 41, the groove wall of the installation groove 41 is provided with a limiting protrusion 212, the mounting base 4 has a mounting protrusion 21 that cooperates with the installation groove 41, and the elastic arm 211 on the mounting protrusion 21 is provided with a positioning hole 411 that cooperates with the limiting protrusion 212. In this way, the quick replacement of the target plate 2 can also be realized.

[0038] In addition, the single jogging distance of the lifting part of the card electric cylinder 3 can also be greater than 0.1 mm, such as set to 0.2 mm, 0.5 mm or 1 mm, etc. The single jogging distance of the card electric cylinder 3 is set according to the actual on-site situation and through the built-in program. After the puncture is completed, press the origin return button to return to the starting position.

[0039] In another preferred embodiment, as Figure 5 shown, the lower groove wall of the installation groove 41 facing the limit protrusion 212 is provided with a concave limit guide groove 412. The positioning hole 411 is located on the lower groove wall of the limit guide groove 412 and is used to make way for the limit protrusion 212. Specifically, the limit protrusion 212 is an arc-shaped protrusion.

[0040] By sliding the limit protrusion 212 in the limit guide groove 412, it can not only ensure that the limit protrusion 212 does not deviate from the positioning hole 411, so that the limit protrusion 212 can smoothly slide into and be embedded in the positioning hole 411, but also reduce the force required to completely push the installation protrusion 21 into the installation groove 41, thereby further improving the operation convenience of the electric aiming target.

[0041] In another preferred embodiment, as Figure 7 and Figure 8 shown, a through groove 213 penetrating the front and rear surfaces is opened in the left end of the installation protrusion 21 facing the installation groove 41. The lower groove wall of the through groove 213 facing the positioning hole 411 is elastic, and the lower groove wall of the through groove 213 facing the positioning hole 411 is the elastic arm 211.

[0042] During specific implementation, by opening a through groove 213 at the left end of the installation protrusion 21, the elastic arm 211 is in a suspended state, and the thickness of the elastic arm 211 is also reduced accordingly, so as to ensure that the elastic arm 211 has a certain elasticity and forms a small deformation to cooperate to form a elastic force limit.

[0043] The number of elastic arms 211 is 1. The number of limit protrusions 212 on the elastic arm 211 is two, and the number of positioning holes 411 is also two. The two limit protrusions 212 and the positioning holes 411 correspond one by one, with a simple and reliable structure.

[0044] Of course, in other embodiments, the number of elastic arms 211 can also be two, that is, the upper and lower groove walls of the through groove 213 can both be elastic arms 211. Each elastic arm 211 has a set of limit protrusions 212. Correspondingly, the upper and lower groove walls of the installation groove 41 are also provided with a set of positioning holes 411 each. The two sets of limit protrusions 212 and the positioning holes 411 correspond one by one, and in this way, rapid disassembly and assembly can also be achieved.

[0045] In another preferred embodiment, as Figure 1 and Figure 4As shown, a fixing base 5 for assembling the ultrasonic probe 1 is fixed to the fixing part of the card electric cylinder 3, and the ultrasonic probe 1 is detachably mounted on the fixing base 5.

[0046] More specifically, as Figure 4 shown, the fixing base 5 is equipped with a rotatable buckle 6, and has a relief groove 51 for the ultrasonic probe 1 and a clamping groove 53 for restricting the rotation of the buckle 6. The lower end of the buckle 6 is assembled on the groove wall of the relief groove 51 through a pin shaft 7, and the upper end of the buckle 6 is detachably clamped in the clamping groove 53. The buckle 6 and the relief groove 51 together form a fixing cavity for clamping the ultrasonic probe 1.

[0047] In this specific embodiment, the fixing base 5 is also provided with a relief chute 52 for the lower end of the target plate 2 as Figure 4 shown, towards the top of the target plate 2, so as to prevent structural interference between the target plate 2 and the fixing base 5 and facilitate the installation of the target plate 2.

[0048] When the ultrasonic probe 1 needs to be installed on the fixing base 5, first, forcefully release the clamping restriction between the upper end of the buckle 6 and the clamping groove 53, and then rotate the buckle 6 downward to insert the ultrasonic probe 1 into the relief groove 51. Then rotate the buckle 6 upward so that the buckle 6 surrounds the outer peripheral surface of the ultrasonic probe 1 until the upper end of the buckle 6 is clamped in the clamping groove 53, so as to fix the buckle 6 on the fixing base 5, and thus complete the Figure 1 clamping and fixing of the ultrasonic probe 1 as shown.

[0049] If the ultrasonic probe 1 needs to be removed, only need to forcefully release the clamping restriction between the upper end of the buckle 6 and the clamping groove 53 to release the clamping and fixing of the ultrasonic probe 1.

[0050] Although the present invention is specifically shown and described in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them fall within the protection scope of the present invention.
