Description

Technical Field

[0001] The present invention relates to the medical field, and in particular to a puncture device suitable for ultrasonic interventional surgery. Background Art

[0002] Ultrasound interventional surgery, a minimally invasive diagnostic and treatment technique guided by ultrasound imaging, requires precision, safety, and ease of use during puncture. As the core tool for this procedure, the puncture device must simultaneously perform multiple functions, including puncture positioning, disinfectant delivery, and flow control.

[0003] Currently, common ultrasonic interventional surgical puncture devices on the market have the following technical defects: Inadequate disinfectant flow control precision: Existing devices often use a simple push-button liquid release mechanism and lack an adjustable flow control mechanism. This makes it difficult to precisely adjust the amount of disinfectant flowing out during surgery based on actual needs (such as puncture depth and surgical site). Excessive flow can easily lead to disinfectant waste and tissue damage, while too little flow can result in incomplete disinfection and increase the risk of infection.

[0004] Based on this, we proposed a puncture device suitable for ultrasound interventional surgery. Summary of the Invention

[0005] In order to solve the technical problem of insufficient precision in flow control of disinfectant in the prior art, the present invention provides a puncture device suitable for ultrasonic interventional surgery.

[0006] The present invention is implemented by the following technical solution: a puncture device suitable for ultrasonic interventional surgery, comprising a puncture device body, the puncture device body including a pressing handle component for puncture operation; a pressing mechanism for controlling the outflow of disinfectant; and a flow control mechanism for controlling the flow of liquid; The push handle assembly includes a handle, the outer side of which is connected to a movable shaft, the top of which is connected to the upper mounting frame, the handle and the movable shaft being connected via a first axis, and the handle and the upper mounting frame being connected via a second axis; the bottom end of the movable shaft being connected to a receiving rod, which is engaged in a sliding groove provided on the surface of the upper mounting frame; the outer side of the upper mounting frame is fixedly mounted with a handle, the lower mounting frame being connected below the upper mounting frame, the surface of the lower mounting frame being provided with a movable groove, the inner side of which is engaged with a moving block; the receiving rod and the moving block being connected via a rod body, and the moving block slides inside the movable groove.

[0007] The outer side of the moving block is fixedly connected to a push block, which is fixedly connected to a moving rod. The outer side of the moving rod is fixedly connected to a puncture device, which is fixedly connected to a puncture needle. The push block is installed inside the shaft frame. A support column is fixedly installed on the surface of the shaft frame, and the top of the support column is fixedly connected to a support platform.

[0008] The outer side of the moving block is connected to a connecting rod on the pressing mechanism. A mounting sleeve is sleeved on the surface of the connecting rod. The connecting rod and the movable rod are integrally connected. The top of the connecting rod is fixedly connected to a receiving frame. The top of the receiving frame is fixedly connected to a pressing rod. The top of the pressing rod is connected to a piston head. The piston head extends into the interior of the liquid chamber. The surface of the liquid chamber has a liquid inlet. The liquid chamber is connected to the control valve chamber.

[0009] The flow control mechanism includes a control valve chamber and a handle. An adjusting screw is connected below the handle. A limit plate is sleeved on the surface of the adjusting screw. A limit bolt is provided on the surface of the limit plate. A fixing bolt column is installed below the limit bolt. A fixing column is installed at the bottom end of the fixing bolt column. A mounting rod is connected below the adjusting screw, a support rod is installed below the mounting rod, a movable axis is installed at the end of the support rod away from the mounting rod, a clamping block is connected at the end of the movable axis away from the support rod, a moving block is installed on the inner side of the clamping block, a buffer spring is connected to the inner side of the moving block, a pull rod is connected to the outer side of the buffer spring, the top of the pull rod is connected to a sealing plate, and a valve port is opened at the top of the control valve cavity.

[0010] As a further optimization solution of the present invention, the flow control mechanism is mounted on the support platform. The support column and the support platform fix the flow control mechanism, and the shaft frame supports the movement of the push block and the puncture needle, ensuring that the puncture operation and the disinfection process are carried out synchronously, thereby improving the efficiency of the operation.

[0011] As a further optimization scheme of the present invention, the pushing block outside the moving block drives the puncture device and the puncture needle to move linearly in the axis frame through the moving rod to achieve precise puncture. At the same time, the pressing mechanism synchronously completes the pushing of the disinfectant liquid, forming an integrated "puncture-disinfection" operation.

[0012] As a further optimization scheme of the present invention, the three groups of piston heads respectively reciprocate inside the liquid chamber, and an openable and closable liquid inlet is provided at the top of the liquid chamber, so that the liquid can be stored in the liquid chamber, and the liquid and high-pressure gas can be injected from the liquid chamber of the injection chamber into the interior of the control valve chamber through the reciprocating motion of the liquid chamber.

[0013] As a further optimization scheme of the present invention, through the cooperation of high-pressure gas, the liquid passes through the control valve cavity and flows out from the valve port. The valve port is connected to the flow tube. The liquid rushes into the flow tube under high pressure and enters the flow head, and is sprayed out from the disinfectant nozzle to disinfect the punctured wound. As a further optimization of the present invention, the gap between the sealing plate and the valve port is controlled, thereby controlling the liquid flow rate at the valve port and adjusting the gap between the sealing plate and the valve port. A larger gap increases the liquid flow rate; conversely, a smaller gap decreases the flow rate, thereby precisely controlling the outflow of disinfectant. This facilitates better control of the outflow of disinfectant, thereby achieving more effective puncture and flushing.

[0014] As a further optimization solution of the present invention, the sealing plate is made of rubber and seals the valve port. The outer side of the valve port is connected to a flow tube, the outer side of the flow tube is connected to a flow head, and the outer side of the flow head is fixedly connected to a disinfectant spray head.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Utilizing the adjustable function of the flow control mechanism, this invention allows medical personnel to rotate the handle to drive the adjusting screw, moving the sealing plate up and down, precisely adjusting the gap between it and the valve port, thereby controlling the flow of disinfectant. This design addresses the insufficient flow control precision of existing devices, avoiding waste and tissue damage caused by excessive flow, while also preventing incomplete disinfection caused by insufficient flow, thereby improving surgical safety.

[0016] 2. The present invention achieves integrated control of the puncture operation and disinfectant delivery through the linkage design of the push handle component and the push mechanism. When the doctor presses the handle, it not only drives the puncture needle for precise puncture, but also simultaneously drives the piston head to reciprocate within the liquid chamber, injecting disinfectant and high-pressure gas into the control valve chamber and spraying them out through the nozzle, reducing the number of operation steps and improving surgical efficiency.

[0017] 3. The present invention ensures the stability of the overall structure of the device by securing the flow control mechanism with a support column and support platform, and supporting the movement of the puncture needle with a shaft frame. This structural design allows the puncture and disinfection processes to proceed simultaneously, reducing the doctor's distraction during operation. At the same time, the ergonomic grip design also reduces fatigue after prolonged operation, further improving the convenience and comfort of the procedure. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example 1: Please combine Figures 1-6 This embodiment provides a puncture device suitable for ultrasonic interventional surgery, including a puncture device body 1, which includes a pressing handle component 2 for puncture operation; a pressing mechanism 5 for controlling the outflow of disinfectant; and a flow control mechanism 6 for controlling the flow of liquid; The pressing handle component 2 includes a handle 21, a movable shaft 22 is connected to the outer side of the handle 21, and the top end of the handle 21 is connected to the upper mounting frame 23. The handle 21 and the movable shaft 22 are connected via a first axis 24, and the handle 21 and the upper mounting frame 23 are connected via a second axis 25. The bottom end of the movable shaft 22 is connected to a connecting rod 26, which is engaged in a sliding groove 27 provided on the surface of the upper mounting frame 23. A handle 28 is fixedly mounted on the outside of the upper mounting frame 23. A lower mounting frame 29 is connected below the upper mounting frame 23. The surface of the lower mounting frame 29 is provided with a movable groove 210, and a moving block 211 is engaged inside the movable groove 210. The connecting rod 26 and the moving block 211 are connected by a rod body, and the moving block 211 slides inside the movable groove 210.

[0022] The outer side of the motion block 211 is fixedly connected to a push block 212, to which a motion rod 213 is fixedly connected. The outer side of the motion rod 213 is fixedly connected to a puncture device 214, to which a puncture needle 215 is fixedly connected. The push block 212 is mounted inside a shaft frame 216. A support column 3 is fixedly mounted on the surface of the shaft frame 216, to which a support platform 4 is fixedly connected at its top. A flow control mechanism 6 is mounted on the support platform 4. The support column 3 and the support platform 4 secure the flow control mechanism 6. The shaft frame 216 supports the movement of the push block 212 and the puncture needle 215, ensuring that the puncture operation and the disinfection process are carried out synchronously, thereby improving surgical efficiency.

[0023] Specifically, when the doctor holds the grip 28 and presses the handle 21, the handle 21 rotates around the second axis 25, driving the movable shaft 22 to swing through the first axis 24. The receiving rod 26 at the bottom end of the movable shaft 22 slides in the sliding groove 27, pushing the moving block 211 to move outward in the moving groove 210.

[0024] In a further specific solution, the pushing block 212 outside the moving block 211 drives the puncture device 214 and the puncture needle 215 to move linearly in the shaft frame 216 through the moving rod 213 to achieve precise puncture. At the same time, the pressing mechanism 5 synchronously completes the pushing of the disinfectant liquid, forming an integrated "puncture-disinfection" operation.

[0025] The outer side of the motion block 211 is connected to a connecting rod 51 on the pressing mechanism 5. A mounting sleeve 510 is sleeved on the surface of the connecting rod 51. The connecting rod 51 is integrally connected to the movable rod 52. The top of the connecting rod 51 is fixedly connected to a receiving frame 53. The top of the receiving frame 53 is fixedly connected to a pressing rod 54. The top of the pressing rod 54 is connected to a piston head 55. The piston head 55 extends into a liquid chamber 56. A liquid inlet 57 is formed on the surface of the liquid chamber 56. The liquid chamber 56 is connected to the control valve chamber 61.

[0026] In a more specific technical solution, the connecting rod 51 on the outside of the moving block 211 moves downward synchronously, driving the movable rod 52, the receiving frame 53 and the pressing rod 54 to move downward. The movable rod 52 and the receiving frame 53 connected to the top of the connecting rod 51 move synchronously, and the piston head 55 connected to the top of the pressing rod 54 reciprocates. The three groups of piston heads 55 thus reciprocate respectively inside the liquid chamber 56. A liquid inlet 57 that can be opened and closed is provided at the top of the liquid chamber 56, which can store liquid in the liquid chamber 56. Through the reciprocating motion of the liquid chamber 56, the liquid and high-pressure gas are injected from the liquid chamber 56 of the injection chamber into the control valve chamber 61. Since the high-pressure gas and the liquid are injected into the control valve chamber 61 synchronously, through the cooperation of the high-pressure gas, the liquid passes through the control valve chamber 61 and flows out from the valve port 615. The valve port 615 is connected to the flow tube 7. The liquid rushes into the flow tube 7 under high pressure and enters the flow head 8, and is sprayed out from the disinfectant nozzle 9 to disinfect the punctured wound.

[0027] The flow control mechanism 6 includes a control valve chamber 61 and a handle 62. An adjusting screw 63 is connected below the handle 62. A limit plate 64 is sleeved on the surface of the adjusting screw 63. A limit bolt 65 is provided on the surface of the limit plate 64. A fixing bolt column 65 is installed below the limit bolt 65. A fixing column 66 is installed at the bottom end of the fixing bolt column 65. A mounting rod 67 is connected below the adjusting screw 63, and a support rod 68 is installed below the mounting rod 67. A movable axis 69 is installed at the end of the support rod 68 away from the mounting rod 67. A clamping block 610 is connected to the end of the movable axis 69 away from the support rod 68. A moving block 611 is installed inside the clamping block 610. A buffer spring 612 is connected inside the moving block 611. A pull rod 613 is connected outside the buffer spring 612. A sealing plate 614 is connected to the top of the pull rod 613. A valve port 615 is defined at the top of the control valve chamber 61. The sealing plate 614 is made of rubber and seals the valve port 615.

[0028] To control the flow rate of liquid flushing, the medical staff rotates the handle 62, which drives the adjustment screw 63 to rotate. This synchronizes the movement of the mounting rod 67 connected to the bottom of the screw 63, raising the mounting rod 67 to a higher level. This in turn drives the support rod 68 connected to its bottom to rise synchronously. The support rod 68 drives the movable axis 69 and the clamping block 610 to rise synchronously. The clamping block 610 drives the moving block 611 and the buffer spring 612 to move synchronously. The buffer spring 612 then pulls the connected pull rod 613, which drives the connected sealing plate 614 to move, controlling the gap between the sealing plate 614 and the valve port 615. This controls the flow rate of liquid in the valve port 615 and adjusts the gap between the sealing plate 614 and the valve port 615. The larger the gap, the greater the liquid flow rate; conversely, the smaller the flow rate, thereby precisely controlling the outflow of disinfectant. This facilitates better control of the outflow of disinfectant, thereby achieving better puncture flushing.

[0029] Furthermore, the outer side of the valve port 615 is connected to a flow tube 7 , the outer side of the flow tube 7 is connected to a flow head 8 , and the outer side of the flow head 8 is fixedly connected to a disinfectant nozzle 9 .

[0030] Working principle: The linkage principle between puncture operation and pressing mechanism Movement transmission by pressing the handle part When the doctor holds the grip 28 and presses the handle 21, the handle 21 rotates around the second axis 25, driving the movable shaft 22 to swing through the first axis 24. The receiving rod 26 at the bottom end of the movable shaft 22 slides in the sliding groove 27, pushing the moving block 211 to move outward in the moving groove 210.

[0031] Driving principle of puncture needle The pushing block 212 outside the moving block 211 drives the puncture device 214 and the puncture needle 215 to move linearly in the shaft frame 216 through the moving rod 213 to achieve precise puncture. At the same time, the pressing mechanism 5 synchronously completes the pushing of the disinfectant liquid, forming an integrated "puncture-disinfection" operation.

[0032] Liquid push by pressing mechanism The connecting rod 51 on the outside of the moving block 211 moves downward synchronously, driving the movable rod 52, the receiving frame 53 and the pressing rod 54 to move downward. The movable rod 52 and the receiving frame 53 connected to the top of the connecting rod 51 move synchronously, and the piston head 55 connected to the top of the pressing rod 54 reciprocates. The three groups of piston heads 55 reciprocate respectively inside the liquid chamber 56. A liquid inlet 57 that can be opened and closed is provided at the top of the liquid chamber 56, which can store liquid in the liquid chamber 56. Through the reciprocating motion of the liquid chamber 56, the liquid and high-pressure gas are injected from the liquid chamber 56 of the injection chamber into the control valve chamber 61. Since the high-pressure gas and the liquid are injected into the control valve chamber 61 synchronously, through the cooperation of the high-pressure gas, the liquid passes through the control valve chamber 61 and flows out from the valve port 615. The valve port 615 is connected to the flow tube 7. The liquid rushes into the flow tube 7 under high pressure and enters the flow head 8, and is sprayed out from the disinfectant nozzle 9 to disinfect the punctured wound.

[0033] Working principle of flow control mechanism To control the flow rate of liquid flushing, medical personnel rotate handle 62, which drives adjustment screw 63 to rotate. This synchronizes the movement of mounting rod 67 connected to the bottom of screw 63, raising the mounting rod 67 to a higher level. This in turn drives support rod 68 connected to its bottom to rise synchronously. Support rod 68 drives movable axis 69 and clamping block 610 to rise synchronously. Clamping block 610 drives moving block 611 and buffer spring 612 to move synchronously. Buffer spring 612 then pulls connected pull rod 613, which drives connected sealing plate 614 to move, controlling the gap between sealing plate 614 and valve port 615. This controls the flow rate of liquid in valve port 615 and adjusts the gap between sealing plate 614 and valve port 615. A larger gap increases the flow rate; a smaller gap decreases the flow rate, allowing for precise control of the outflow of disinfectant. This facilitates better control of the outflow of disinfectant, resulting in optimal puncture flushing.

[0034] The integrity of structural linkage The support column 3 and the support platform 4 fix the flow control mechanism 6, and the shaft frame 216 supports the movement of the push block 212 and the puncture needle 215, ensuring that the puncture operation and the disinfection process are carried out synchronously, thereby improving the operation efficiency.

[0035] Disinfectant output path The liquid chamber 56 is connected to the control valve chamber 61. After the high-pressure liquid and gas enter the control valve chamber 61, they flow into the flow tube 7 through the valve port 615, and then are sprayed out from the disinfectant nozzle 9 through the flow head 8 to disinfect the puncture wound.

[0036] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
