Description

Technical Field

[0001] This invention relates to the field of CT interventional examination and treatment technology, specifically to a CT interventional examination and treatment guided puncture combination directional device. Background Technology

[0002] CT-guided interventional examination and treatment uses CT as a fine needle to perform biopsies, which can provide a good understanding of the location of the lesion and the internal condition of the body, while avoiding important internal structures. During CT-guided interventional examination and treatment, a positioning and guiding device is required.

[0003] For example, a CT-guided lung puncture fixation guide bracket with publication number CN210130901U includes a pressure ring, which is an annular block. The pressure ring has an annular groove at its top, and a sliding member is provided in the annular groove. The top of the sliding member has an arc-shaped strip, the center of which coincides with the center of the bottom surface of the pressure ring. A pointing rod is vertically provided on the upper part of the inner arc surface of the arc-shaped strip, and the extension line of the pointing rod coincides with the line connecting the centers of the upper and lower surfaces of the pressure ring. This utility model can accurately adjust the needle insertion direction of lung puncture through the arc-shaped strip, sliding member, and pressure ring. Through the angle adjustment block and arc-shaped groove, the needle insertion angle can be accurately adjusted. This device improves the accuracy of needle insertion when doctors use it, reduces the risk of complications such as pneumothorax caused by excessive needle insertion deviation, and ensures that the position of the needle insertion point coincides with the designated needle insertion point before and after adjustment, making it more convenient to use.

[0004] For example, a CT-guided lung puncture fixation guide bracket with publication number CN212490083U includes a connecting plate. Symmetrical sliding rods are fixedly connected to the left side of the connecting plate. A sliding tube is slidably connected to the outer surface of each sliding rod. A sliding plate is fixedly connected to the side of the two sliding tubes that are close to each other. A fixing block is provided on the left side of the connecting plate. A sliding hole is opened on the bottom surface of the fixing block, and the sliding plate is located inside the sliding hole. The outer surface of the sliding plate is slidably connected to the inner wall of the sliding hole. A puncture needle fixing sleeve is fixedly connected to the left side of the fixing block. Two recessed holes are opened on the inner side wall of the sliding hole. A spring is fixedly connected to the inner bottom wall of each recessed hole, and a fixing pad is fixedly connected to the left end of each spring. This CT-guided lung puncture fixation guide bracket facilitates adjustment of the guiding angle and position of the puncture needle inside the puncture needle fixing sleeve, avoiding inconvenience for doctors when performing punctures on patients.

[0005] The device described in the above application is inconvenient for quickly fixing and moving the fine needle during use. During surgery, medical staff need to manually operate the fine needle to move it to the corresponding depth, which is a relatively complicated process. At the same time, staff may experience fatigue during surgery, requiring them to concentrate more. However, the device described in the above application does not have a reminder function and has low safety.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing CT-guided puncture and directional devices for interventional CT examinations and treatments. Summary of the Invention

[0007] The purpose of this invention is to provide a CT interventional examination and treatment guided puncture combination orientation device to solve the problems mentioned in the background art, such as the inconvenience of quickly fixing and moving the fine needle during use, the need for medical personnel to manually operate the fine needle to move it to the corresponding depth during surgery, the complexity of the operation process, the lack of a reminder function during use, and the low safety.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a CT interventional examination and treatment guided puncture combination orientation device, comprising a connecting frame and a docking plate, wherein an auxiliary plate is fixedly installed on the surface of the connecting frame at equal angles, and the connecting frame has a hollow structure;

[0009] The docking plate is fixedly installed on the inner wall of the connecting frame, and a limit frame is fixedly installed at the end of the docking plate.

[0010] A CT-guided puncture and orientation device for interventional CT examination and treatment further includes:

[0011] A limiting block, which is slidably connected inside the limiting frame;

[0012] A left connecting plate is fixedly installed on the left side of the connecting frame, and a right connecting plate is fixedly installed on the right side of the connecting frame. A long pin is rotatably connected inside the left connecting plate, and a handle is fixedly installed on the upper surface of the long pin.

[0013] The mounting sleeve has an anti-slip layer fixedly installed on its inner wall, and the surface of the mounting sleeve is open. A side rod is fixedly installed on the right side of the mounting sleeve.

[0014] A connecting shaft is rotatably connected inside the right connecting plate, and the surface of the right connecting plate is recessed, and a gong is fixedly installed on the inner wall of the right connecting plate.

[0015] Preferably, the surface of the long pin is threaded with a crossbar, and a positioning block is fixedly installed on the surface of the long pin. The interior of the left connecting plate is provided with a positioning groove corresponding to the positioning block. In use, the connecting frame and the auxiliary plate are first attached to the skin through conventional operation. At this time, the detection device is inserted into the installation sleeve, and then the operator can rotate the handle, which drives the long pin to rotate inside the left connecting plate.

[0016] Preferably, the positioning blocks are evenly distributed on the surface of the long pin, and the positioning blocks are made of rubber. The crossbar and the mounting sleeve are fixedly connected. When the long pin rotates, the current positioning block will move out of the positioning groove. After the position is determined, the corresponding positioning block will enter the positioning groove. The positioning blocks and positioning groove prevent the long pin from rotating on its own, thus improving stability. At the same time, when the long pin rotates, it drives the crossbar and the mounting sleeve to descend, so that the operator can quickly fix the detection device and move the detection device up and down. The operation process is simple and quick.

[0017] Preferably, sliders are fixedly installed on both the upper and lower sides of the limiting block, and the surface of the limiting block is inclined. The inside of the limiting frame is provided with a sliding groove corresponding to each slider. When the detection device continues to descend and contacts the limiting block, the limiting block is pushed into the limiting frame. At this time, the limiting block drives the slider to slide inside the sliding groove.

[0018] Preferably, a first spring that provides elastic reset is fixedly installed on the side of the limiting block, and the other side of the first spring is fixedly connected to the inner wall of the limiting frame. The limiting blocks are evenly distributed inside the limiting frame. When the limiting block slides, it will squeeze the first spring. As a result, under the action of the first spring, the limiting block always tends to move towards the center of the limiting frame. That is, the limiting block can tightly press against the detection device, ensuring the stability of the detection device when it moves.

[0019] Preferably, a traction rope is fixedly connected to the side of the side rod, and the other side of the traction rope is wound and fixedly connected to the surface of the connecting shaft. A cam is fixedly installed on the surface of the connecting shaft. When the mounting sleeve descends, the mounting sleeve drives the side rod to descend synchronously. At this time, the side rod drives the connecting shaft to rotate through the traction rope. When the connecting shaft rotates, it drives the cam to rotate.

[0020] Preferably, a movable plate is slidably connected inside the right connecting plate, and the left side of the movable plate is in contact with the cam. When the cam rotates, it pushes the movable plate.

[0021] Preferably, the end of the movable plate is slidably disposed inside the right connecting plate, and the right connecting plate has a limiting groove corresponding to the movable plate inside. The limiting groove allows the movable plate to move only in the horizontal direction, thereby improving stability.

[0022] Preferably, a striking block corresponding to the gong is fixedly installed on the surface of the movable plate, and the striking blocks are evenly distributed on the surface of the movable plate. A second spring that provides elastic reset is fixedly installed on the surface of the movable plate, and the other side of the second spring is fixedly connected to the inner wall of the right connecting plate. When the movable plate moves, it compresses the second spring, and at the same time, the movable plate drives the striking blocks to move synchronously. When the connecting shaft and cam continue to rotate, the movable plate and the striking blocks move back under the action of the second spring. Repeating the above process, the movable plate and the striking blocks make reciprocating linear motion in the horizontal direction, so that the striking blocks can strike the gong repeatedly, making the gong sound, which serves as a warning and makes the working process safer.

[0023] Preferably, a torsion spring with elastic reset function is fixedly installed on the surface of the connecting shaft, and the other side of the torsion spring is fixedly connected to the inner wall of the right connecting plate. A protective net is fixedly installed on the surface of the right connecting plate. When the connecting shaft rotates, the connecting shaft will stretch the torsion spring. When the operator turns the handle and the long pin, the mounting sleeve and the side rod rise. At this time, the connecting shaft loses the tension of the traction rope, and then the connecting shaft rotates under the action of the torsion spring. When the connecting shaft rotates, the traction rope will be wound up for the next use. The protective net prevents the gong from making a false sound.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the CT interventional examination and treatment guided puncture combination directional device adopts a novel structural design, the specific details of which are as follows:

[0025] (1) When using the CT interventional examination and treatment guided puncture combination orientation device, firstly, through conventional operation, the connecting frame and auxiliary plate are attached to the skin. At this time, the detection device is inserted into the installation sleeve. Then, the staff can rotate the handle and the long pin. The long pin drives the crossbar and the installation sleeve to descend. That is, the staff can quickly fix the detection device and move the detection device up and down. The operation process is simple and quick. When the detection device descends, it will squeeze the limiting block. Then the limiting block will slide to the side of the limiting frame. Then the limiting block will squeeze the first spring. That is, under the action of the first spring, the limiting block always tends to move towards the middle of the limiting frame. The limiting block can tightly hold the detection device and ensure the stability of the detection device when it moves.

[0026] (2) When the installation sleeve descends, the installation sleeve drives the side rod to descend synchronously. At this time, the side rod drives the connecting shaft and cam to rotate through the traction rope. At this time, the movable plate and the striking block make reciprocating linear motion in the horizontal direction under the action of the cam, the limiting groove and the second spring. Then the striking block can strike the gong repeatedly, making the gong sound, which plays a warning and reminder role, making the working process safer.

[0027] (3) When the connecting shaft rotates, the connecting shaft will stretch the torsion spring. When the staff turns the handle and the long pin, the mounting sleeve and the side rod rise. At this time, the connecting shaft loses the tension of the traction rope. Then the connecting shaft rotates under the action of the torsion spring. When the connecting shaft rotates, the traction rope will be wound up for the next use (at the same time, the cam will drive the movable plate and the striking block to work again, so that the gong will work again, which also serves as a warning and reminder).

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-9 The present invention provides a technical solution: a CT interventional examination and treatment guided puncture combination orientation device, including a connecting frame 1 and a docking plate 3. An auxiliary plate 2 is fixedly installed at equal angles on the surface of the connecting frame 1, and the connecting frame 1 has a hollow structure. The docking plate 3 is fixedly installed on the inner wall of the connecting frame 1, and a limit frame 4 is fixedly installed at the end of the docking plate 3.

[0040] A CT-guided puncture and orientation device for interventional CT examination and treatment further includes:

[0041] Limiting block 5 is slidably connected inside the limiting frame 4. Left connecting plate 6 is fixedly installed on the left side of the connecting frame 1, and right connecting plate 7 is fixedly installed on the right side of the connecting frame 1. Long pin 8 is rotatably connected inside the left connecting plate 6, and handle 9 is fixedly installed on the upper surface of the long pin 8.

[0042] Mounting sleeve 11, with an anti-slip layer 12 fixedly installed on the inner wall of mounting sleeve 11, and the surface of mounting sleeve 11 is open, and a side rod 18 and a connecting shaft 19 are fixedly installed on the right side of mounting sleeve 11. The connecting shaft 19 is rotatably connected to the inside of the right connecting plate 7, and the surface of the right connecting plate 7 is recessed, and a gong 23 is fixedly installed on the inner wall of the right connecting plate 7.

[0043] The surface of the long pin 8 is threaded with a crossbar 10, and a positioning block 13 is fixedly installed on the surface of the long pin 8. The interior of the left connecting plate 6 is provided with a positioning groove 14 corresponding to the positioning block 13. The positioning blocks 13 are evenly distributed on the surface of the long pin 8, and the positioning blocks 13 are made of rubber. The crossbar 10 and the mounting sleeve 11 are fixedly connected.

[0044] The upper and lower sides of the limiting block 5 are fixedly installed with sliders 15, and the surface of the limiting block 5 is inclined. The inside of the limiting frame 4 is provided with sliding grooves 16 that correspond one-to-one with the sliders 15. The side of the limiting block 5 is fixedly installed with a first spring 17 that plays an elastic reset role, and the other side of the first spring 17 is fixedly connected to the inner wall of the limiting frame 4. The limiting blocks 5 are evenly distributed inside the limiting frame 4.

[0045] In use, the connecting frame 1 and auxiliary plate 2 are first attached to the skin using conventional methods. Then, the detection device is inserted into the mounting sleeve 11. The operator can then rotate the handle 9 and the long pin 8. The long pin 8 causes the crossbar 10 and the mounting sleeve 11 to descend, allowing the operator to quickly fix and move the detection device up and down. The operation is simple and quick. When the detection device descends, it will press the limiting block 5, causing the limiting block 5 to slide towards the side of the limiting frame 4. The slider 15 and the slide groove 16 limit the movement distance of the limiting block 5, ensuring stability. At the same time, the limiting block 5 will press the first spring 17, meaning that under the action of the first spring 17, the limiting block 5 always tends to move towards the center of the limiting frame 4. The limiting block 5 can firmly hold the detection device in place, ensuring the stability of the detection device during movement.

[0046] A traction rope 20 is fixedly connected to the side of the side rod 18, and the other side of the traction rope 20 is wrapped and fixedly connected to the surface of the connecting shaft 19. A cam 26 is fixedly installed on the surface of the connecting shaft 19. A movable plate 22 is slidably connected inside the right connecting plate 7, and the left side of the movable plate 22 is in contact with the cam 26. The end of the movable plate 22 is slidably disposed inside the right connecting plate 7, and a limiting groove 28 corresponding to the movable plate 22 is opened inside the right connecting plate 7.

[0047] The surface of the movable plate 22 is fixedly equipped with striking blocks 24 corresponding to the gong 23, and the striking blocks 24 are evenly distributed on the surface of the movable plate 22. The surface of the movable plate 22 is also fixedly equipped with a second spring 25 that plays an elastic reset role, and the other side of the second spring 25 is fixedly connected to the inner wall of the right connecting plate 7.

[0048] When the mounting sleeve 11 descends, it drives the side rod 18 to descend synchronously. At this time, the side rod 18 drives the connecting shaft 19 and the cam 26 to rotate through the traction rope 20. At this time, the movable plate 22 and the striking block 24 reciprocate linearly in the horizontal direction under the action of the cam 26, the limit groove 28, and the second spring 25. As a result, the striking block 24 can strike the gong 23 repeatedly, making the gong 23 make a sound, which serves as a warning and reminder, and makes the working process safer.

[0049] A torsion spring 27, which plays an elastic reset role, is fixedly installed on the surface of the connecting shaft 19, and the other side of the torsion spring 27 is fixedly connected to the inner wall of the right connecting plate 7. A protective net 21 is fixedly installed on the surface of the right connecting plate 7.

[0050] When the connecting shaft 19 rotates, it will stretch the torsion spring 27. When the operator turns the handle 9 and the long pin 8, the crossbar 10, the mounting sleeve 11 and the side bar 18 rise. At this time, the connecting shaft 19 loses the tension of the traction rope 20. Then, the connecting shaft 19 rotates under the action of the torsion spring 27. When the connecting shaft 19 rotates, it will rewind the traction rope 20 for the next use (at the same time, the cam 26 will drive the movable plate 22 and the striking block 24 to work again, so that the gong 23 will work again, which also serves as a warning and reminder).
