Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for hepatobiliary puncture, and specifically to a method and equipment for hepatobiliary surgical puncture. Background Technology

[0002] Liver biopsy is a procedure performed by taking a liver tissue sample. Generally, under the guidance of an ultrasound probe, the puncture site is located—a location with fewer blood vessels corresponding to the liver disease. Then, a puncture needle is inserted, and an anesthetic is injected through the needle. During the injection, the syringe can be slightly moved to allow the needle tip to inject the anesthetic over a large area of ​​the liver capsule. Finally, the biopsy gun is connected to another needle to aspirate a suitable amount of liver tissue for examination. Any blood, medication, or other fluids that spill out during the procedure should be wiped away with a cotton cloth. The puncture site is then located using an ultrasound probe. After determining the optimal puncture location, the doctor needs to hold the puncture site with one hand or mark it with a medical marker to facilitate subsequent targeted punctures. The process of locking the puncture site is complex and requires significant manpower. After the puncture needle is inserted into the body, the doctor needs to support the needle with one hand and then insert the syringe or biopsy gun tube onto the needle. Often, turning the body to retrieve the medical instruments causes the other hand to shake the needle, which can easily lead to the needle being misaligned and puncturing other parts of the patient's body. Furthermore, after the needle is inserted at an angle, the space between the needle and the skin is smaller, making it difficult to wipe away blood, medication, or other fluids with a cotton cloth. Summary of the Invention

[0003] To overcome the aforementioned technical problems, the present invention aims to provide a method and device for hepatobiliary surgical puncture. By rotating the semi-circular guide rail on the rotating seat, one end of the semi-circular guide rail is attracted and fixed to the corresponding movable seat. At this time, the two clamps can be moved away from the puncture position, expanding the visible space of the puncture position. Then, the puncture needle, after being injected with anesthetic, is moved to the middle position of the semi-circular guide rail. At this time, the center of the semi-circular guide rail corresponds to the center of the annular support block. The puncture needle is then moved downwards to achieve precise insertion into the liver capsule region. Then, the threaded rod is rotated to move the arc-shaped rod from the bottom of the semi-circular guide rail towards the puncture needle, facilitating the fixation of the puncture needle after puncture and preventing accidental injury to the other end when turning to retrieve the medical puncture instrument. With your hand holding the puncture needle, after inserting the syringe containing anesthetic into the top of the puncture needle, remove the curved rod. At this time, the puncture needle can swing slightly along the semi-circular through hole on the semi-circular guide rail. At the same time, you can rotate the position of the semi-circular guide rail on the annular support block to make the puncture needle swing slightly in different directions, which makes it easier for the puncture needle to inject the anesthetic over a large area of ​​the patient's location. Rotate the square tube to make the square slide rod bring the wiping cotton on the disc closer to the skin. Rotate the second moving seat to the direction of inclination close to the puncture needle, which makes it easier for the circular wiping cotton to wipe the liquid in the small space of the puncture site. At the same time, you can use your fingers to turn the groove on the disc to make the disc rotate with the wiping cotton, which makes it easy to change the wiping cotton to wipe the liquid at different edges.

[0004] The objective of this invention can be achieved through the following technical solutions: A hepatobiliary surgical puncture device includes an annular support block with an elastic band between its two ends. A rotating seat is slidably engaged with the top surface of the annular support block, along with two rotating seats and three movable seats. A semi-circular guide rail is rotatably connected to the top of each rotating seat. A semi-circular through-hole is formed in the center of the semi-circular guide rail, and two puncture needles are slidably inserted into the through-hole. The bottom of the semi-circular guide rail... The unit is equipped with a semi-circular limiting rod for fixing the position of the puncture needle. A clamp is rotatably connected to the top of the rotating seat two. The clamp includes an arc-shaped rod rotatably connected to the rotating seat two. A clamping plate is fixed to one end of the arc-shaped rod away from the rotating seat two. A cleaning component is provided on the inner ring of the annular support block. The cleaning component includes a movable seat two that is slidably engaged with the inner ring of the annular support block. A telescopic component is rotatably connected to the inner side of the movable seat two. A disc is rotatably connected to the top of the telescopic component. A wiping cotton is detachably fixed to the outer side of the disc. Furthermore, the inner ring of the annular support block has an annular groove 2 that is slidably engaged with the movable seat 2. The movable seat 2 includes a square tube that is rotatably connected to the movable seat 2, and a square slide rod is slidably engaged inside the square tube.

[0005] Furthermore, the disc is rotatably connected to a connecting shaft at its center, and the end of the connecting shaft facing away from the disc is inserted and fixed to a square sliding rod. The disc has multiple grooves at equal angles on the side near the connecting shaft.

[0006] Furthermore, the top surface of the annular support block is provided with an annular groove, and the rotating seat one, rotating seat two, and moving seat one are all slidably engaged with the annular groove one.

[0007] Furthermore, the puncture needle has two rubber balls that can be detachably snapped onto its outer side. The outer side of the rubber balls has a notch, and a rubber pad that contacts the outer side of the puncture needle is fitted and fixed to the inner side of the semi-circular through hole.

[0008] Furthermore, the rotating seat 2 has a bolt movably inserted inside, with pads fixed at both ends of the bolt. The bolt passes through the arc-shaped rod at the corresponding position. One end of the semi-circular guide rail is fixed with a magnet 1, and the top surface of the movable seat 1 is embedded with a magnet 2 that is attracted and abuts against the magnet 1.

[0009] Furthermore, the bottom of both ends of the semi-circular guide rail is fixed with a fixing block. One of the fixing blocks is fixed with a guide shaft that is slidably inserted into the semi-circular limiting rod, and the other fixing block is rotatably connected with a threaded rod that is screwed into the semi-circular guide rail. A rubber pad is fixedly sleeved on the outer side of the semi-circular limiting rod.

[0010] Furthermore, connecting blocks are fixed to the outer sides of both ends of the annular support block, one end of the elastic fabric strip is inserted and fixed to the corresponding connecting block, one end of the elastic fabric strip passes through the corresponding connecting block, and one end of the elastic fabric strip is fixed with Velcro.

[0011] A method for hepatobiliary surgical puncture, the method specifically including the following steps: Step 1: Slide the elastic band onto the patient's body, rotate the arc-shaped rods on the two clamps to hold and fix the probe in place using the two clamps, and hold the clamps to allow the probe to explore the best puncture point on the skin. Step 2: After the probe finds the best puncture point, pull the movable end of the elastic cloth and use the Velcro on the movable end of the elastic cloth to tie the elastic cloth band tightly to the patient's body, so that the support block is fixed to the patient's body. At this time, the center of the ring support block is the puncture point. Step 3: Take out two puncture needles and insert them into the semi-circular through holes of the semi-circular guide rail. Secure the puncture needles to the semi-circular guide rail by attaching rubber balls to the top and bottom of the puncture needles. Step 4: Rotate the semi-circular guide rail so that one end of it is attached and fixed to the corresponding position moving seat 1. Move the needle 1 to the middle position of the semi-circular guide rail, and then puncture downwards. Rotate the threaded rod and arc rod to move towards the puncture needle and fix the punctured needle 1. Step 5: Insert the syringe containing the anesthetic into the puncture needle and inject the anesthetic. After inserting the syringe containing the anesthetic into the top of the puncture needle, remove the curved rod. At this time, the needle can swing slightly along the semi-circular through hole on the semi-circular guide rail, injecting the anesthetic over a large area to the patient's location. Step Six: Remove Needle One, point the tip of Needle Two at the puncture site, and puncture the central area of ​​the annular support block. Then, insert the biopsy gun tube into Needle Two and extract liver tissue. During the puncture, the semi-circular guide rail can be rotated to allow Needle Two to puncture the puncture site from different directions.

[0012] The beneficial effects of this invention are: 1. By attaching the elastic band to the patient's upper body and positioning the annular support block on the skin outside the liver, rotate the arc-shaped rods on the two clamps to move the two clamps closer together, thereby using the two clamps to hold and fix the probe. Then, by holding the clamps, the probe is used to search for the optimal puncture point on the skin. At this time, the position pointed by the probe is the center of the annular support block. After the probe finds the optimal puncture position, pull the movable end of the elastic band to fix the annular support block on the patient's body. At this time, the center of the annular support block is the puncture point, eliminating the need to use a marker or mark it by hand again. 2. By rotating the semi-circular guide rail on the rotating seat, one end of the semi-circular guide rail is attracted and fixed to the corresponding position of the moving seat. At this time, the two clamps can be moved away from the puncture position to expand the visible space of the puncture position. Then, the puncture needle for injecting anesthetic is moved to the middle position of the semi-circular guide rail. At this time, the center of the semi-circular guide rail corresponds to the center of the annular support block. Then, the puncture needle is moved down to achieve precise insertion of the puncture needle into the liver capsule area. Then, the threaded rod is rotated to move the arc rod from the bottom of the semi-circular guide rail towards the puncture needle, which is convenient to fix the puncture needle after puncture and prevent the other hand from shaking the puncture needle when turning the body to pick up the medical puncture instrument. After inserting the syringe containing anesthetic into the top of the puncture needle, the semi-circular limiting rod is removed. At this time, the puncture needle can swing slightly along the semi-circular through hole on the semi-circular guide rail. At the same time, the position of the semi-circular guide rail on the annular support block can be rotated to make the puncture needle swing slightly in different directions, which is convenient for the puncture needle to inject anesthetic into a large area of ​​the patient's position. 3. By attaching two rubber balls to the outside of the puncture needle and placing them one above the other on the top and bottom of the semi-circular guide rail, the puncture needle is fixed on the semi-circular guide rail, preventing the position of the puncture needle from changing after puncture. At the same time, it is convenient to pre-install two puncture needles on the semi-circular guide rail for use, eliminating the process of frequently taking out the puncture needle. 4. By tilting the puncture needle for extracting liver biopsy tissue onto the semi-circular guide rail, the needle can be precisely inserted into the body after anesthesia injection, as long as it is aligned with the center of the annular support block. Similarly, two rubber balls can be used to fix the puncture needle tilted onto the semi-circular guide rail. When it is necessary to clean the small space between the puncture needle and the skin at an acute angle to remove blood or medication, rotate the square tube to bring the square slide rod with the wiping cotton on the disc closer to the skin. Rotate the second moving seat to the direction closer to the tilt of the puncture needle, so that the circular wiping cotton can wipe the liquid in the small space of the puncture site clean. At the same time, you can use your fingers to move the groove on the disc to make the disc rotate with the wiping cotton, so that you can change the wiping cotton to wipe the liquid at different edge positions. 5. By moving the two rotating seats two closer to each other along the annular support block, the clamp can be stored and stored, preventing the clamp from taking up a large puncture space when it is later unfolded. Multiple movable seats two are rotatably connected on the annular support block, so that the semi-circular guide rail can still be overlapped and fixed to the movable seats one at different positions after the two clamps are stored close together.

[0017] Please see Figure 1-9 A hepatobiliary surgical puncture device is shown, comprising an annular support block 100, with elastic bands 200 between its two ends. A rotating seat 110 is slidably engaged with the top surface of the annular support block 100, two rotating seats 120 are slidably engaged with the top surface of the annular support block 100, and three movable seats 130 are slidably engaged with the top surface of the annular support block 100. A semi-circular guide rail 300 is rotatably connected to the top of the rotating seat 110. A semi-circular through hole is formed in the middle of the semi-circular guide rail 300, and two puncture needles 400 are slidably inserted into the semi-circular through hole. A device for fixing the puncture needles is provided at the bottom of the semi-circular guide rail 300. A semi-circular limiting rod 310 is located at the needle position 400. A clamp 500 is rotatably connected to the top of the rotating seat 2 120. The clamp 500 includes an arc-shaped rod 510 rotatably connected to the rotating seat 2 120. A clamping plate 520 is fixed to one end of the arc-shaped rod 510 away from the rotating seat 2 120. A cleaning component 600 is provided on the inner ring of the annular support block 100. The cleaning component 600 includes a movable seat 2 610 that is slidably engaged with the inner ring of the annular support block 100. A telescopic component 620 is rotatably connected to the inner side of the movable seat 2 610. A disc 630 is rotatably connected to the top of the telescopic component 620. A wiping cotton 640 is detachably fixed to the outer side of the disc 630.

[0018] The inner ring of the annular support block 100 has an annular groove 2 that slides and engages with the movable seat 2 610. The movable seat 2 610 includes a square tube 621 rotatably connected to the movable seat 2 610. A square slide rod 622 is slidably engaged inside the square tube 621. The square slide rod 622 can slide out different lengths inside the square tube 621, which facilitates moving the wiping cotton 640 on the disc 630 to a position close to the puncture needle 400. A connecting shaft 631 is rotatably connected to the middle of the disc 630. The end of the connecting shaft 631 opposite to the disc 630 is connected to the square tube 622. The slide rod 622 is inserted and fixed. The disc 630 has multiple grooves 632 at equal angles on one side near the connecting shaft 631. The disc 630 can be rotated by hand by moving the grooves 632, and then the disc 630 wipes blood at different positions on the wiping cotton 640. The top surface of the annular support block 100 has an annular slot 140. The rotating seat 110, rotating seat 2 120 and moving seat 130 are all slidably engaged with the annular slot 140, which facilitates the movement of the rotating seat 110, rotating seat 2 120 and moving seat 130 along the arc trajectory.

[0019] Two rubber balls 410 are detachably snapped onto the outer side of the puncture needle 400. The outer side of the rubber balls 410 has a notch 411. A rubber pad 1 that contacts the outer side of the puncture needle 400 is sleeved and fixed inside the semi-circular through hole. The rubber balls 410 facilitate fixing the puncture needle 400 onto the semi-circular guide rail 300. The rubber pad 1 protects the outer side of the puncture needle 400 and also securely fixes the puncture needle 400 inside the semi-circular guide rail 300. A bolt 121 is movably inserted into the interior of the rotating seat 120. Both ends of the bolt 121 are fixed with pads. The bolt 121 passes through the corresponding arc rod 510. A magnet 1 is fixed to one end of the semi-circular guide rail 300. A magnet 2 that attracts and abuts the magnet 1 is embedded and fixed to the top surface of the moving seat 130. The bolt 121 facilitates fixing the position of the moved arc rod 510. The magnet 1 and the magnet 2 are opposite magnets, which facilitates fixing the semi-circular guide rail 300 to the top of the annular support block 100.

[0020] The bottom of both ends of the semicircular guide rail 300 is fixed with fixing blocks 320. One fixing block 320 is fixed with a guide shaft 321 that slides into the semicircular limiting rod 310. The other fixing block 320 is rotatably connected with a threaded rod 322 that screws into the semicircular guide rail 300. A rubber pad is fixed to the outer side of the semicircular limiting rod 310, so that the semicircular limiting rod 310 can press and fix the puncture needles 400 at different positions on the semicircular guide rail 300 onto the semicircular guide rail 300. The outer sides of both ends of the annular support block 100 are fixed with connecting blocks 150. One end of the elastic band 200 is inserted and fixed to the corresponding connecting block 150. One end of the elastic band 200 passes through the corresponding connecting block 150. One end of the elastic band 200 is fixed with a Velcro. The Velcro consists of a female Velcro and a female Velcro to bind the elastic band 200 to the patient's body.

[0021] A method for hepatobiliary surgical puncture device, the method specifically includes the following steps: Step 1: Attach the elastic band 200 to the patient's body, rotate the arc rod 510 on the two clamps 500 to clamp and fix the probe with the two clamps 520, and hold the clamps 520 to make the probe explore the best puncture point on the skin. Step 2: After the probe finds the optimal puncture position, pull the movable end of the elastic band 200 and use the Velcro on the movable end of the elastic band 200 to tie and fix the elastic band 200 to the patient's body, so that the annular support block 100 is fixed to the patient's body. At this time, the center of the annular support block 100 is the puncture point. Step 3: Take out two puncture needles 400 and insert them into the semi-circular through holes of the semi-circular guide rail 300. Secure rubber balls 410 to the puncture needles 400 near the top and bottom of the semi-circular guide rail 300 to fix the puncture needles 400 to the semi-circular guide rail 300. Step 4: Rotate the semi-circular guide rail 300 so that one end of it is attached and fixed to the corresponding position moving seat 130. Move the needle to the middle position of the semi-circular guide rail 300 and then puncture downwards. Rotate the threaded rod 322 and the semi-circular limiting rod 310 to move towards the puncture needle 400 to fix the punctured needle. Step 5: Insert the syringe containing the anesthetic into the puncture needle 400 and inject the anesthetic. After inserting the syringe containing the anesthetic into the top of the puncture needle 400, remove the semi-circular limiting rod 310. At this time, the needle can swing slightly along the semi-circular through hole on the semi-circular guide rail 300 to inject the anesthetic into a large area of ​​the patient's position. Step Six: Remove Needle One, point the tip of Needle Two at the puncture site, and puncture the central area of ​​the annular support block 100. Then, insert the biopsy gun tube into Needle Two and extract liver tissue. During the puncture, the semi-circular guide rail 300 can be rotated to allow Needle Two to puncture the puncture site from different directions.

[0022] Working principle: In use, the elastic band 200 is placed on the patient's body, but not tightened. This allows the annular support block 100 to move on the skin. Then, the arc-shaped rods 510 on the two clamps 500 are rotated to move the two clamping plates 520 closer together. The bolts 121 on the rotating seat 120 are then tightened, using the two clamping plates 520 to hold and fix the probe. The probe is then moved along the skin by holding the clamping plates 520, searching for the optimal puncture point. Simultaneously, the annular support block 100 moves on the skin. The position pointed to by the probe is the center of the annular support block 100. Once the probe finds the optimal puncture point, the movable end of the elastic band 200 is pulled, using the Velcro on the movable end to tighten and fix the elastic band 200 to the patient's body, thus fixing the annular support block 100 to the patient's body. The center of the annular support block 100 is now the puncture point (refer to the instruction manual for this process). Figure 9 Then rotate the two arc rods 510 to their initial positions, referring to the instruction manual. Figure 8 The two rotating seats 120 are moved closer to each other to store the clamp 500, preventing the clamp 500 from occupying the visible space during the puncture process when not in use. Then, the two puncture needles 400 are taken out and inserted into the semi-circular through holes of the semi-circular guide rail 300. Rubber balls 410 are installed on the puncture needles 400 near the top and bottom of the semi-circular guide rail 300. The rubber balls 410 are used to fix the puncture needles 400 on the semi-circular guide rail 300. For the convenience of explaining the working principle below, the puncture needle 400 used for injecting anesthetic is referred to as needle one, and the puncture needle 400 used for extracting liver biopsy tissue is referred to as needle two. Rotate the semi-circular guide rail 300 so that one end of it is magnetically attached to the corresponding movable seat 130 (refer to the instruction manual). Figure 7At this point, move needle one to the middle position of the semicircular guide rail 300, and then puncture downwards to the liver capsule area. Then rotate the threaded rod 322 and the semicircular limiting rod 310 to move from the bottom of the semicircular guide rail 300 towards the puncture needle 400 to fix needle one after puncture. Next, take out the syringe containing anesthetic and insert it into the puncture needle 400 to inject anesthetic. After inserting the syringe containing anesthetic into the top of the puncture needle 400, remove the semicircular limiting rod 310. At this time, needle one can swing slightly along the semicircular through hole on the semicircular guide rail 300. Of course, the position of the semicircular guide rail 300 on the annular support block 100 can be rotated to make needle one swing slightly in different directions, so that needle one can inject anesthetic over a large area of ​​the patient's location. When it is necessary to use needle two to puncture and extract liver tissue, needle one can be removed, and then the tip of needle two can be pointed towards the puncture site. The central area of ​​the annular support block 100 is punctured, and then the needle of the biopsy gun is inserted into the second needle to extract liver tissue. During the puncture, the semi-circular guide rail 300 can be rotated to allow the second needle to puncture the puncture site from different directions. Sometimes it is necessary to find a position that is both in the puncture site and convenient for the operator to operate manually, so it is necessary to change the direction of puncture. Finally, when it is necessary to clean the fluid between the puncture needle 400 and the skin, rotate the square tube 621 to bring the square slide rod 622 with the wiping cotton 640 of the disc 630 close to the skin, and rotate the second moving seat 610 to the inclined direction close to the puncture needle 400, so that the circular wiping cotton 640 can wipe the fluid in the small space of the puncture site clean. At the same time, the groove 632 on the disc can be turned with the finger to make the disc 630 rotate with the wiping cotton 640, so that the fluid can be wiped from different edge positions of the wiping cotton 640.

9. The method for a hepatobiliary surgical puncture device according to claim 8, characterized in that, The method specifically includes the following steps: Step 1: Place the elastic band (200) on the patient's body, rotate the arc rod (510) on the two clamps (500) and use the two clamps (520) to clamp and fix the probe, hold the clamps (520) and use the probe to find the best puncture point on the skin. Step 2: After the probe finds the best puncture position, pull the movable end of the elastic band (200) and use the Velcro on the movable end of the elastic band (200) to tie the elastic band (200) tightly to the patient's body, so that the annular support block (100) is fixed to the patient's body. At this time, the center of the annular support block (100) is the puncture point. Step 3: Take out two puncture needles (400) and insert them into the semi-circular through holes of the semi-circular guide rail (300). Secure rubber balls (410) to the top and bottom of the puncture needles (400) near the top and bottom of the semi-circular guide rail (300) to fix the puncture needles (400) on the semi-circular guide rail (300). Step 4: Rotate the semi-circular guide rail (300) so that one end of it is attached and fixed to the corresponding position moving seat (130). Move the needle to the middle position of the semi-circular guide rail (300) and then puncture downwards. Rotate the threaded rod (322) and the semi-circular limiting rod (310) moves towards the puncture needle (400) to fix the punctured needle. Step 5: Insert the syringe for anesthetic into the puncture needle (400) to inject the anesthetic, remove the semi-circular limiting rod (310), at this time the needle can swing slightly along the semi-circular through hole on the semi-circular guide rail (300) to inject the anesthetic over a large area to the patient's location. Step 6: Remove needle one, point the tip of needle two at the puncture site, and puncture the central area of ​​the annular support block (100). Then, insert the biopsy gun tube into needle two and extract liver tissue. During the puncture, the semi-circular guide rail (300) can be rotated to allow needle two to puncture the puncture site in different directions.
