Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a puncture guide device for thoracic surgery. Background Art

[0002] When performing thoracic positioning puncture, the puncture skin at the puncture site needs to be fixed, and the puncture needle is slowly inserted vertically at the puncture point. When the puncture needle feels a breakthrough, it indicates that it has entered the pleural cavity. At this time, the puncture needle needs to be fixed, and then the pleural effusion is extracted.

[0003] Currently, in the existing technology, thoracic positioning puncture requires the cooperation of two people and cannot be performed by a doctor alone, which wastes manpower and leads to poor coordination and cooperation between the two people, resulting in poor puncture results.

[0004] In addition, there is a possibility of backflow when the puncture needle is pulled out after aspirating body cavity secretions. The operator needs to continuously apply external force to the piston of the syringe to prevent it from backflowing. At the same time, the external force applied should not be too large to prevent the suction force from being too strong, which causes the operator to be under great pressure. Continuously applying external force to the piston can easily make the operator tired, which may cause the operator's hand to be unstable, and then cause the puncture needle to shake and cause harm to the patient's body.

[0042] See also Figures 1 to 9 As shown, the present invention provides a puncture guide device for thoracic surgery, comprising a mounting base 1, wherein a pushing portion 2 is provided inside the mounting base 1, and the pushing portion 2 can slide inside the mounting base 1;

[0043] The pushing portion 2 is provided with a mounting portion 3 inside, and the pushing portion 2 drives the mounting portion 3 to extend and slide inside the mounting base 1;

[0044] An extractor 4 is provided inside the mounting portion 3, and the extractor 4 can be conveniently fixed and installed through the mounting portion 3;

[0045] At the same time, the pusher 2 can also pull the extractor 4 so that the extractor 4 extracts the material at the puncture site;

[0046] A guide portion 5 is provided at one end of the mounting base 1. The interior of the guide portion 5 cooperates with the extraction end of the extractor 4. The interior of the guide portion 5 can display the puncture position of the extraction end of the extractor 4 on the patient's chest through a laser indicator.

[0047] A control unit 6 is provided at the lower end of the mounting base 1. The control unit 6 is capable of controlling the sliding distance of the pushing unit 2 and receiving pressure data of the pushing unit 2 and switch data of the guiding unit 5.

[0048] The guide part 5 includes a guide seat 501, a guide shell 502, a laser pointer 503 and a pressure switch 504. The guide seat 501 is fixedly connected to one end of the mounting base 1, the guide shell 502 is slidingly connected to the guide seat 501, and the inner side of the guide shell 502 cooperates with the extraction end of the extractor 4. The laser pointer 503 is fixedly connected to the inner side of the guide shell 502, and the output end of the laser pointer 503 cooperates with the collection end of the extractor 4. The pressure switch 504 is arranged between the guide seat 501 and the guide shell 502, and the pressure switch 504 is electrically connected to the control part 6.

[0049] Specifically, when a puncture operation is required on a patient, the operator needs to hold the mounting base 1, and then press and fix the extractor 4 inside the mounting part 3, and then the operator presses the mounting part 3 to fix the mounting part 3 inside the pushing part 2, so that the extractor 4 is parallel to the mounting base 1, and then the guide part 5 is placed at the position where the patient needs to be punctured, and the guide shell 502 is in contact with the patient's skin, and the laser of the laser pointer 503 is used to accurately align the extraction end of the extractor 4 with the puncture position, and then the operator holds the mounting base 1 and moves it toward the patient, so that the guide shell 502 slides on the guide seat 501, and the guide shell 502 squeezes the pressure switch 504, so that the pressure switch 504 transmits the power-on signal to the control part 6, so that the control part 6 receives the preparation completion signal. The control unit 6 controls the pushing unit 2 to first drive the mounting unit 3 and the extractor 4 to move toward the patient's puncture site, until the extraction end of the extractor 4 enters the predetermined extraction position in the patient's body, and then the control unit 6 controls the pushing unit 2 to pull the extractor 4, so that a negative pressure space is formed inside the extractor 4, so that the extraction end of the extractor 4 can extract the extraction target in the patient's body, until the extractor 4 extracts enough liquid, and then the control unit 6 controls the pushing unit 2 to drive the mounting unit 3 and the extractor 4 to move, so that the extraction end of the extractor 4 is moved out of the patient's body, and then the operator takes the mounting base 1 away from the patient's puncture site, and then presses the mounting unit 3 so that the mounting unit 3 pops out of the interior of the pushing unit 2, and then the extractor 4 can be moved out of the interior of the mounting unit 3 for processing, thereby completing the puncture operation on the patient.

[0050] See also Figures 1 to 4 As shown, the entire guide shell 502 is set to a transparent material. The transparent guide shell 502 can enable the operator to better observe the indicated position of the laser pointer 503 and the puncture status of the extractor 4, thereby improving the puncture accuracy of the operator.

[0051] See also Figures 2 to 4 As shown, the elastic pressure of the press-fire switch 504 is greater than the friction between the guide housing 502 and the guide seat 501, so that the guide housing 502 is always squeezed by the elastic pressure of the press-fire switch 504 itself and is in an extended state.

[0052] See also Figures 1 to 6As shown, the pushing portion 2 includes an electric pushing rod 201, a pressure sensor 202, a pushing seat 203, an electric extraction rod 204 and a pulling seat 205. The electric pushing rod 201 is fixedly connected to the interior of the mounting base 1, one end of the pressure sensor 202 is fixedly connected to the output end of the electric pushing rod 201, one end of the pushing seat 203 is fixedly connected to the other end of the pressure sensor 202, the electric extraction rod 204 is fixedly connected to the interior of the pushing seat 203, and the output end of the electric extraction rod 204 is also provided with a pressure sensor 202, and the pulling seat 205 is fixedly connected to the output end of the electric extraction rod 204;

[0053] When the pushing part 2 performs the puncture operation, the electric pushing rod 201 drives the mounting part 3 and the extractor 4 inside the pushing seat 203 to move toward the puncture site of the patient, and the data of the extension distance of the output end of the electric pushing rod 201 is recorded. At the same time, the pressure sensor 202 monitors the pressure when the electric pushing rod 201 drives the mounting part 3 to move toward the patient in real time, and obtains the pressure data when the extractor 4 punctures the patient. The control part 6 analyzes the extension data and pressure data to determine the puncture distance and pressure of the puncture end of the extractor 4, thereby determining the position reached by the puncture end of the extractor 4, thereby improving the puncture accuracy of the extractor 4;

[0054] When the pushing part 2 performs the extraction operation, the pulling seat 205 is driven to move by the output end of the electric extraction rod 204, so that the pulling seat 205 pulls the handle of the extractor 4, obtains the pressure data of the extractor 4 during extraction, and forms a negative pressure space inside the extractor 4, so that the extractor 4 extracts the extraction target in the patient's body, thereby completing the puncture extraction of the target in the patient's body.

[0055] See also Figures 1 to 6 As shown, a pulling groove is provided inside the pulling seat 205, and the pulling groove cooperates with the pulling handle of the extractor 4. The inside of the pulling groove is provided with an inclined shape. In the process of the pulling seat 205 pulling the extractor 4, the pulling handle of the extractor 4 is squeezed by the inclined structure inside the pulling groove and slightly tilted and deformed, thereby preventing the pulling handle from detaching from the inside of the pulling groove during movement, causing pulling failure.

[0056] See also Figures 2 to 4 as well as Figure 7 、 Figure 8As shown, the mounting portion 3 includes a mounting seat 301, a lifting rod 302, an elastic extrusion member 303, a locking block 304 and an elastic return member 305. One end of the mounting seat 301 is rotatably connected to the interior of the pushing seat 203, one end of the lifting rod 302 is slidably connected to the interior of the mounting seat 301, and the other end of the lifting rod 302 is rotatably connected to the interior of the pushing seat 203. The elastic extrusion member 303 is arranged between the interior of the mounting seat 301 and the lifting rod 302. The locking block 304 is slidably arranged inside the mounting seat 301, and one end of the locking block 304 is matched with the interior of the pushing seat 203. The elastic return member 305 is arranged between the locking block 304 and the mounting seat 301.

[0057] When the mounting portion 3 is in the pop-up state, the mounting portion 3 is installed into the pushing seat 203, and pressure is applied to the mounting seat 301 to apply pressure to the pushing seat 203, so that the mounting seat 301 rotates toward the pushing seat 203. At this time, one end of the lifting rod 302 slides inside the mounting seat 301 and squeezes the elastic squeezing member 303 to shrink until the mounting seat 301 is completely inside the pushing seat 203. At this time, the mounting seat 301 is parallel to the mounting base 1. At this time, the locking block 304 is squeezed by the elastic return member 305 and extends out of the mounting seat 301 and is stuck in the pushing seat 203, thereby locking the mounting seat 301 and the pushing seat 203.

[0058] When the mounting portion 3 is installed inside the pushing portion 2, it is necessary to press the locking block 304 to retract it into the mounting seat 301. At this time, the locking block 304 is released from the lock with the pushing seat 203, and then one end of the lifting rod 302 is squeezed by the elastic extrusion piece 303 and slides inside the mounting seat 301, and the other end of the lifting rod 302 rotates inside the pushing seat 203. At this time, one end of the mounting seat 301 rotates inside the pushing seat 203, and the entire mounting seat 301 tilts, so that the extractor 4 inside the mounting seat 301 is exposed to the interior of the pushing seat 203, thereby facilitating the convenient removal of the extractor 4 and improving the convenience of using the equipment.

[0059] See also Figure 3 and Figure 4 As shown, the lifting rod 302 is arranged in an inclined state between the pushing seat 203 and the mounting seat 301. Through the inclined state of the lifting rod 302, when the lifting rod 302 is squeezed by the elastic squeezing member 303, the lifting rod 302 can apply the squeezing force to the mounting seat 301, causing the mounting seat 301 to tilt and rotate, thereby avoiding the lifting rod 302 from being in a horizontal stuck state and ensuring the rotation of the mounting seat 301.

[0060] See also Figures 1 to 4As shown, the entire mounting base 301 is made of plastic, and an arc-shaped mounting groove is provided on the inner side of the mounting base 301, the inner side of which matches the outer edge of the extractor 4. Due to the elasticity of the plastic itself, when the extractor 4 is installed into the interior of the mounting base 301, it is necessary to place the extractor 4 at the opening of the mounting base 301, and then squeeze the extractor 4 hard to cause the opening of the mounting base 301 to deform and expand until the extractor 4 is completely inserted into the interior of the mounting base 301. The mounting base 301 then restores its shape and fixes the extractor 4 inside, thus achieving convenient fixation of the extractor 4 and improving operational convenience.

[0061] See also Figure 7 and Figure 8 When the cam 303 is in the unlock state, the locking block 304 is locked and the locking hole 305 is locked, so that the locking block 304 can be locked in the unlock state.

[0062] See also Figures 1 to 4 As shown, the control unit 6 includes a handle 601, a power supply unit 602, a control unit 603 and a control button 604. The handle 601 is fixedly connected to the mounting base 1. The handle 601 can make it more convenient for the operator to hold the device in hand. The power supply unit 602 is fixedly connected to the inside of the handle 601. The power supply unit 602 is a rechargeable battery pack. The control unit 603 is fixedly connected to the inside of the mounting base 1. The control unit 603 has a built-in display and a processor. The control unit 603 is electrically connected to the power supply unit 602. The power supply unit 602 is used for the control unit 604. 03 is powered, and the control unit 603 is electrically connected to the laser pointer 503, the electric pushing rod 201, the pressure sensor 202, and the electric extraction rod 204. The control unit 603 distributes power to the operation of each component, analyzes the pressure data returned by the pressure sensor 202, and monitors the operation of each component. A plurality of control buttons 604 are provided on the mounting base 1, and all are electrically connected to the control unit 603. The control buttons 604 can be used to adjust the relevant parameters of the electric pushing rod 201 and the electric extraction rod 204 in the processor, thereby increasing the flexibility of the device.

[0063] It should be noted that one of the control buttons 604, the pressure switch 504 and the control unit 603 are connected in series, and the start signal is doubly ensured by the control button 604 and the pressure switch 504, ensuring that the puncture instruction can be issued to the control unit 603 through the control button 604 only after contact with the patient to avoid misoperation of the equipment.

[0064] The working principle of the present invention is as follows: when a puncture operation is required on a patient, the operator is required to hold the mounting base 1, and then press and fix the extractor 4 inside the mounting part 3, and then the operator presses the mounting part 3 to fix the mounting part 3 inside the pushing part 2, so that the extractor 4 is parallel to the mounting base 1, and then the guide part 5 is placed at the position where the patient needs to be punctured, and the guide shell 502 is in contact with the patient's skin, and the laser of the laser pointer 503 is used to accurately align the extraction end of the extractor 4 with the puncture position, and then the operator holds the mounting base 1 and moves it toward the patient, so that the guide shell 502 slides at the guide seat 501, and the guide shell 502 squeezes the pressure switch 504, so that the pressure switch 504 transmits the power-on signal to the control part 6, so that the control part 6 receives the accurate puncture position. The control unit 6 then controls the pushing unit 2 to first drive the mounting unit 3 and the extractor 4 to move toward the patient's puncture site, until the extraction end of the extractor 4 enters the predetermined extraction position in the patient's body, and then the control unit 6 controls the pushing unit 2 to pull the extractor 4, so that a negative pressure space is formed inside the extractor 4, so that the extraction end of the extractor 4 can extract the extraction target in the patient's body, until the extractor 4 extracts enough liquid, and then the control unit 6 controls the pushing unit 2 to drive the mounting unit 3 and the extractor 4 to move, so that the extraction end of the extractor 4 is moved out of the patient's body, and then the operator takes the mounting base 1 away from the patient's puncture site, and then presses the mounting unit 3 so that the mounting unit 3 pops out of the interior of the pushing unit 2, and then the extractor 4 can be moved out of the interior of the mounting unit 3 for processing, thereby completing the puncture operation on the patient.

[0065] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention.
