Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a puncture needle auxiliary moving device for an ovarian puncture system. Background Art

[0002] Traditional ovarian puncture surgeries have limitations such as high operation difficulty, limited accuracy, and relatively large harm to the animal body. Due to the influence of the individual skill level and state of the operator, it is difficult to ensure the consistency and standardization of the surgery. At the same time, manual puncture surgeries cannot provide real-time imaging guidance, which limits the accuracy of positioning and puncture. Therefore, introducing machine-assisted technology or other advanced auxiliary technologies may be an important way to improve ovarian puncture surgeries.

[0003] In recent years, puncture techniques have been innovated and developed in aspects such as machine assistance, real-time imaging technology, automated systems, and new tool materials. For example, a research team at Huazhong University of Science and Technology proposed a puncture machine system based on visual feedback. This system uses deep learning algorithms to achieve accurate positioning and tracking of the target area, thereby improving the accuracy and controllability of puncture surgeries. The innovation of this technology lies in the full utilization of computer vision and artificial intelligence technologies, providing a new solution for precise interventional surgeries. Another example is that Chinese Patent CN 116077155 A discloses a puncture method and related device based on an optical tracking device and a robotic arm, but it requires the movement of the puncture needle to be achieved through the linkage of multiple robotic arms, and the cost of such highly intelligent precision equipment is very high. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a puncture needle auxiliary moving device for an ovarian puncture system with a lower cost, and to achieve the movement of the puncture needle with a relatively simpler action principle.

The lead screw motor can drive the lead screw to rotate, and further drive the lifting block to drive the puncture needle to move up and down.

[0013] More preferably, the micro-adjustment mechanism includes an upper electric cylinder and a lower electric cylinder horizontally installed on the base. The telescopic rod of the upper electric cylinder is connected to the upper part of the support, and the telescopic rod of the lower electric cylinder is connected to the lower part of the support.

[0030] For the convenience of those skilled in the art to understand, the present utility model will be further described below in conjunction with the embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0031] It should be noted in advance that in the present utility model, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection", "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. In addition, in the present utility model, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but through additional features between them.

[0032] Such as Figures 1 to 4As shown in the figure, a puncture needle auxiliary moving device for an ovarian puncture system includes: a base 1 for installing a puncture needle 2 and driving the puncture needle 2 to move; a translation mechanism for driving the base 1 to move forward and backward or left and right along a horizontal plane; a lifting mechanism installed on the base 1 and used to drive the puncture needle 2 to move up and down; a micro-adjustment mechanism installed on the base 1 and used to drive the puncture needle 2 to move in the front-back direction; and an angle adjustment mechanism installed on the base 1 and used to drive the puncture needle 2 to swing in the left-right direction to adjust the angle of the puncture needle 2.

[0033] The above-mentioned translation mechanism includes a slider 3 connected to the base 1. The slider 3 is slidably connected to a first slide rail 4. Both ends of the first slide rail 4 are respectively connected to a second slide rail 6 perpendicular to the first slide rail 4 through a slide seat 5. The second slide rail 6 is installed on a frame 20. The slider 3 can move along the first slide rail 4 to drive the base 1 to move left and right along the horizontal plane, and the slide seat 5 can move along the second slide rail 6 to drive the base 1 to move forward and backward along the horizontal plane. Through the combination of the movement of the slider 3 along the first slide rail 4 and the movement of the slide seat 5 along the second slide rail 6, the front-back and left-right movement of the base 1 on the horizontal plane is realized, providing the flexible positioning ability of the puncture needle 2 in the surgical area. The second slide rail 6 installed through the frame 20 provides a stable support for the entire translation mechanism, ensuring the stability and reliability of the base 1 during the movement.

[0034] It should be noted that there are many ways for the slider 3 to move along the first slide rail 4 and the slide seats 5 at both ends of the first slide rail 4 to move along the second slide rail 6. Those skilled in the art can adopt any existing method to achieve this. For example, using a servo motor in cooperation with a ball screw can accurately control the moving distance and speed of the slider 3 and the slide seat 5. The servo motor can receive control signals to achieve precise position control. For example, the first slide rail 4 includes a screw rod and a guide rod arranged parallel up and down. A nut threadedly connected to the screw rod is installed in the slider 3 and a motor is configured. The motor is fixedly installed in the slider 3. When the motor drives the nut to rotate, the nut can move along the screw rod to drive the slider 3 to move. For the movement of the slide seat 5, a conveyor belt (not shown in the attached drawings) can be arranged along the extension direction of the second slide rail 6. Both ends of the conveyor belt are arranged on the frame 20, and a motor is installed at one end to drive the conveyor belt to run. The slide seat 5 is fixedly connected to the belt surface of the conveyor belt. When the motor drives the conveyor belt to run, the slide seat 5 can be driven to move. Or a mechanism with the same movement mode as the slider 3 can also be set. Those skilled in the art have no technical obstacles to driving the movement of the slider or the slide seat on the corresponding slide rail.

[0035] The lifting mechanism includes a support 7 installed on the base 1, a lead screw 8 vertically arranged on the support 7, a lifting block 9 threadedly connected to the lead screw 8, and a lead screw motor drivingly connected to the lead screw 8. The support 7 is provided with a guiding groove 10 for restricting the rotation of the lifting block 9. The puncture needle 2 is installed on the lifting block 9. The lead screw motor can drive the lead screw 8 to rotate, thereby driving the lifting block 9 to drive the puncture needle 2 to move up and down. By driving the lead screw 8 to rotate with the lead screw motor, the precise up and down movement of the lifting block 9 is realized, so as to control the vertical position of the puncture needle 2 to adapt to the puncture requirements at different depths. The design of the lifting mechanism simplifies the operation process, enabling the operator to easily adjust the height of the puncture needle and improving the efficiency of the operation.

[0036] The micro-adjustment mechanism includes an upper electric cylinder 11 and a lower electric cylinder 12 horizontally installed on the base 1. The telescopic rod of the upper electric cylinder 11 is connected to the upper part of the support 7, and the telescopic rod of the lower electric cylinder 12 is connected to the lower part of the support 7. The upper electric cylinder 11 and the lower electric cylinder 12 can push or pull the support 7 to make the support 7 move back and forth. Through the telescoping of the electric cylinders, the micron-level back and forth movement of the support 7 can be realized, providing fine adjustment of the position of the puncture needle 2 to meet the requirements of high-precision surgery. Moreover, the rapid telescoping ability of the electric cylinders enables the support 7 to quickly respond to the position adjustment requirements, improving the response speed and efficiency of the operation.

[0037] The angle adjustment mechanism includes a rotary motor 13 fixedly installed at one end of the telescopic rod of the upper electric cylinder 11. One end of the output shaft of the rotary motor 13 is fixedly connected to the upper part of the support 7 for driving the support 7 to swing left and right. An arc-shaped groove is formed on the front end face of the bottom of the base 1, and a swing rod 14 is inserted into the arc-shaped groove, and the front end of the swing rod 14 is fixedly connected to the support 7. A transmission assembly is connected between the lower electric cylinder 12 and the swing rod 14. The transmission assembly includes a driving gear 15 coaxially and fixedly installed on the telescopic rod of the lower electric cylinder 12, a driven gear 16 fixedly installed on the swing rod 14 and meshing with the driving gear 15. Two push plates 17 are respectively and fixedly connected to the telescopic rod of the lower electric cylinder 12 on the front and rear sides of the driving gear 15. An arc-shaped through hole 18 for the swing rod 14 to pass through is provided at the bottom of the push plate 17. Two fixing blocks 19 are fixedly installed on the swing rod 14 for respectively abutting against the corresponding push plates 17.

[0038] When the lower electric cylinder 12 pushes or pulls the two push plates 17, the corresponding push plate 17 can push the corresponding fixing block 19, thereby driving the swing rod 14 to move synchronously, that is, the swing rod 14 moves back and forth synchronously with the telescopic rod of the lower electric cylinder 12, realizing the pushing or pulling of the swing rod 14 on the support 7. In this way, by synchronously cooperating with the pushing and pulling actions of the telescopic rod of the upper electric cylinder 11, the displacement fine adjustment of the support 7 can be realized. Among them, one end of the swing rod 14 is only inserted into the arc-shaped groove and is not substantially connected to the arc-shaped groove. As long as a sufficient insertion depth is set, there is no need to worry about the swing rod 14 slipping out of the arc-shaped groove.

[0039] Through the design of the rotating motor 13 and the transmission assembly, the left-right swing of the support 7 is realized, providing multi-dimensional adjustment of the puncture needle angle to meet the complex surgical angle requirements. When the rotating motor 13 works, the support 7 swings left and right with the axis of the output shaft of the rotating motor 13 as the rotation center. During this process, the bottom of the support 7 drives the swing rod 14 to swing synchronously. The arc-shaped groove of the base 1 and the arc-shaped through hole 18 of the push plate 17 provide sufficient space for the swing of the swing rod 14. At the same time, the connection between the driving gear 15 and the driven gear 16 also improves the stability of the support 7 during the swing process.

[0040] The puncture needle auxiliary moving device for the ovarian puncture system provided by the above embodiment can be combined with the existing accurate positioning and tracking technology of the target area and applied to the clinical treatment process to drive the puncture needle to move. By integrating the translation, lifting, fine-tuning and angle adjustment mechanisms, it realizes the accurate positioning and movement of the puncture needle in the three-dimensional space, thereby improving the accuracy and safety of the ovarian puncture surgery, reducing the harm to the patient during the surgery, and reducing the dependence on the operator's skills through automated operation, making the surgical process more standardized and repeatable, and ultimately improving the surgical efficiency and success rate.

[0041] In order to make it more convenient for those of ordinary skill in the art to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
