Description

Technical Field

[0001] This invention relates to the field of hemostasis during hepatobiliary tumor surgery, specifically a hemostasis device for hepatobiliary tumor surgery. Background Technology

[0002] During the intraoperative procedures for hepatobiliary tumors, due to the differences and details between different patients and different parts, local trauma bleeding may occur in the local area due to pathological abnormalities or differences. Current intraoperative hemostasis methods generally use hemostatic forceps and other instruments to stop bleeding in venous vessels. However, hemostatic forceps are not practical for large-area capillary bleeding. In general, internal hemostasis is performed by pressing directly. When performing pressure hemostasis, the procedure requires locating the bleeding site accurately. If necessary, medical cotton swabs or gauze strips should be used to fill the bleeding site. Then, pressure should be applied to the outside of the wound to stop the bleeding. Under hemostasis conditions, the time for a single pressure hemostasis is generally between 5 and 6 minutes. If necessary, pressure hemostasis should be repeated. In order to make the pressure hemostasis effect more stable, the external force applied during pressure hemostasis is relatively large, which is a continuous application of external force for pressure hemostasis. The existing compression hemostasis procedure, which involves manual compression by medical staff, is convenient, but under high-intensity and continuous intraoperative conditions, it significantly increases the physical and mental exhaustion of medical staff, affecting the subsequent tumor surgery.

[0003] To address the aforementioned issues, there is an urgent need for innovative designs based on existing hemostatic devices used in hepatobiliary tumor surgery. Summary of the Invention

[0004] The purpose of this invention is to provide a hemostatic device for hepatobiliary tumor surgery, in order to solve the problem mentioned in the background art that the existing hemostatic procedures for hepatobiliary tumor surgery, which are performed by medical personnel through manual compression, greatly increase the labor and mental energy consumption of medical personnel and affect the subsequent tumor surgery.

[0008] Preferably, a positioning pin is movably installed through the fixed connection between the positioning electromagnet and the steering ball. The positioning pins are evenly distributed at equal angles around the periphery of the positioning electromagnet, and an annular connecting piece is provided between the bottoms of the positioning pins. A permanent magnet plate is also fixed inside the connecting piece, and an elastic element is fixed between the bottom of the connecting piece and the inside of the steering ball. The permanent magnet plate is arranged in a ring shape, and the permanent magnet plate and the positioning electromagnet are vertically coaxially distributed. The magnetic poles on the top surface of the permanent magnet plate are the same as the working magnetic poles at the bottom of the positioning electromagnet.

[0009] Preferably, the side cross-section of the positioning soft strip is set as a "T" shaped structure, and the nodes at the beginning, end and middle of the positioning soft strip are evenly distributed and bonded to the inner wall of the pressure bag, and the bottom of the entire positioning soft strip is attached to the bottom inner wall of the pressure bag.

[0010] Preferably, the pressure rod is disposed between two parallel positioning soft strips, and the beginning and end of the pressure rod are configured as "n"-shaped, with the "n" end slidingly attached to the outer wall of the positioning soft strip, while the middle section of the pressure rod slidesly attached to the inner wall of the bottom of the pressure bag.

[0011] Preferably, an electric telescopic rod is fixed in the middle of the hemostatic frame, and an adjusting push rod is fixed at the output shaft end of the electric telescopic rod. The adjusting push rod is slidably connected to the side of the hemostatic frame, and the bottom of the adjusting push rod is set with a strip-shaped sawtooth structure.

[0012] Preferably, the adjusting push rod is configured as an "n" shaped structure, and the middle part of the adjusting push rod is fixedly connected to the electric telescopic rod perpendicularly. The "n" shaped corner node of the adjusting push rod is a through-hole movable setting, and a pressure sensor is installed at its through-hole.

[0013] Preferably, the top of the hemostatic frame is also fixed with a liquid cavity, a liquid sealing plate is movably installed in the liquid cavity, an elastic element is fixed between the liquid sealing plate and the liquid cavity, and a liquid guiding hose is installed through the liquid cavity and the telescopic positioning rod. An electrically controlled valve is fixed at the point where the liquid guiding hose passes through the telescopic positioning rod, and the electrically controlled valve is electrically connected to the pressure sensor.

[0014] Preferably, the liquid seal plate and the liquid guiding hose are arranged in a one-to-one correspondence, and a sealed sliding connection is provided between the outer side of the liquid seal plate and the inner wall of the liquid cavity, and a pressure vent is provided on the outer wall of the middle part of the liquid cavity.

[0015] Compared with the prior art, the beneficial effects of this invention are: the hemostatic device for hepatobiliary tumor surgery is easy to operate, freeing the hands of medical personnel during surgery, and can stably and effectively achieve precise pressure hemostasis at the bleeding site, facilitating hemostasis operations at different sites. Its specific details are as follows: 1. The middle section of the support is equipped with multiple rotatable free nodes. The rotation and limiting of the node positions are electromagnetically controlled, which facilitates the positioning of the connector and its bottom components. The bottom of the connector is connected to the handle via a steering ball. The bottom of the handle is fitted with a pressure bag via a hemostatic frame. The pressure bag expands to achieve hemostasis by introducing external gas. During this process, the connector and handle can be easily adjusted and changed in angle under the action of the steering ball. At the same time, the positioning electromagnet is set up to make the handle easy and quick to position when it deflects with the steering ball. 2. Simultaneously, through the installation of the permanent magnet plate and elastic element, the positioning pin utilizes the repulsive force between the magnetic poles. Under normal use of the positioning electromagnet, the positioning pin is stored due to the repulsive force of the same magnetic poles. When the positioning electromagnet is damaged, the positioning pin can be engaged with the groove hole on the inner wall of the positioning housing through the elastic repulsion of the elastic element. This achieves a temporary limiting effect on the overall orientation of the connector and the handle, preventing the handle from loosening during compression hemostasis during surgery and affecting the stability of the compression hemostasis operation. 3. Hemostasis is achieved by directly applying pressure to the wound site using a hemostatic frame and pressure bag. Due to the large area of ​​the pressure bag, the application of external pressure to the local hemostasis site is not precise. The position of the adjusting push rod is moved by an electric telescopic rod. The adjusting push rod moves and directly meshes with the gear ring, which in turn directly drives the telescopic positioning rod to rotate and adjust. The telescopic positioning rod and the pressure rod at its end apply external pressure to the bottom of the pressure bag, so that the pressure bag has a more precise force concentration position in the middle under the action of pressure hemostasis, and the effect of pressure hemostasis is more stable. At the same time, the bottom node installation of the positioning soft strip will not affect the bending deformation of the bottom of the pressure bag. 4. The fluid chamber and its internal fluid seal plate are movable and set up so that when the telescopic positioning rod is deflected at an angle or when external force is applied to the patient's wound position, the free extension and retraction of the telescopic positioning rod can be easily adjusted, preventing the telescopic positioning rod from being directly limited by its own length, which would affect the stability of its compression hemostasis at the patient's wound position.

[0018] 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. Example 1

[0019] Please see Figures 1-7 This invention provides a technical solution: a hemostatic device for hepatobiliary tumor surgery, comprising: a support 1, with a connector 2 fixedly installed at its end, and a handle 3 provided at the bottom of the connector 2. The upper end of the handle 3 is movably connected to the connector 2 via a steering bead 4, and an auxiliary telescopic rod 5 is installed through the bottom of the connector 2 at equal angles. A spring is provided inside the auxiliary telescopic rod 5, and an electromagnetic pin 6 is fixed on the middle section of the auxiliary telescopic rod 5. The auxiliary telescopic rod 5 is used for auxiliary limiting of the handle 3; a hemostatic frame 7, which is fixed to the lower end of the handle 3, and a pressure bag 8 is provided at the bottom of the hemostatic frame 7. The handle 3 is hollow, and a pipe is fixedly connected to the top outer wall of the handle 3 for controlling the introduction and export of gas in the pressure bag 8. In the above technical solution, firstly, because the bracket 1 has multiple rotating nodes in its middle section, and the rotation and limiting of the node positions are electromagnetically controlled, it is convenient to change the overall height and position of the connector 2 during use, making the operation convenient. Meanwhile, based on the above scheme, a pressure switch is provided on the outside of the grip 3, and a wrap-around medical rubber sleeve is provided on the outside of the pressure switch. The pressure switch is electrically connected to the electromagnetic pin 6, and the end of the output shaft of the auxiliary telescopic rod 5 is set as an arc-shaped structure. The arc-shaped end of the auxiliary telescopic rod 5 is in contact with the circular outer wall of the grip 3. Adopting such Figures 3-5In the technical solution shown, when adjusting the angle of the grip rod 3, the middle section of the grip rod 3 is directly grasped. The electromagnetic pin 6 is controlled by a pressure switch. Under the external pressure and the elasticity of the spring, the extension and retraction of the auxiliary telescopic rod 5 can be easily controlled. When the pressure switch is not manually controlled, the end of the telescopic rod 5 clamps and supports the outer wall of the grip rod 3 to provide auxiliary positioning at different angles. At the same time, it can prevent the grip rod 3 from falling during installation and application. Example 2

[0020] See Figure 3 and Figure 6 and Figure 7 As shown, based on Embodiment 1, the present invention also provides a rotation limiting mechanism for the grip rod 3 of the hemostatic device, which realizes stable positioning and anti-loosening control of the grip rod 3 in different positions. The specific details are as follows: A positioning electromagnet 401 is fixed through the top center of the steering ball 4. The upper end of the positioning electromagnet 401 is arc-shaped. A positioning housing 402 is embedded inside the connector 2 on the periphery of the steering ball 4. The inner wall of the positioning housing 402 is in contact with the outer wall of the steering ball 4 and the arc-shaped end of the positioning electromagnet 401. The positioning electromagnet 401 is electrically connected to the pressure switch. A positioning pin 403 is movably installed through the fixed connection between the positioning electromagnet 401 and the steering ball 4. The positioning pins 403 are evenly distributed at equal angles around the positioning electromagnet 401. An annular connecting piece is provided between the bottom of the positioning pins 403. A permanent magnet plate 404 is fixed inside the connecting piece. An elastic element 405 is fixed between the bottom of the connecting piece and the inside of the steering ball 4. The permanent magnet plate 404 is arranged in a ring shape, and the permanent magnet plate 404 and the positioning electromagnet 401 are vertically coaxially distributed. The magnetic poles on the top surface of the permanent magnet plate 404 are the same as the working magnetic poles at the bottom of the positioning electromagnet 401. In the above technical solution, the magnetic field of the positioning electromagnet 401 is generated by a pressure switch. The upper and lower ends of the positioning electromagnet 401 generate working magnetism respectively. When the rotation angle of the connector 2 and the grip 3 is changed by the steering bead 4, the magnetic attraction between the positioning electromagnet 401 and the positioning housing 402 can directly achieve the limit of the grip 3 after the angle is changed. At this time, the magnetic pole generated at the bottom of the positioning electromagnet 401 and the magnetic pole of the permanent magnet plate 404 are like poles that repel each other, so that the permanent magnet plate 404 drives the positioning pin 403 to move downward and be housed in the steering bead 4. When the positioning electromagnet 401 is damaged during use, the positioning electromagnet 401 no longer generates magnetism. At the same time, the permanent magnet plate 404 and the positioning pin 403 move upward under the elastic action of the elastic element 405, so that the upper end of the positioning pin 403 is inserted into the concave hole structure of the inner wall of the positioning housing 402, thereby achieving the effect of limiting the grip 3 by the positioning pin 403 and preventing the damage of the positioning electromagnet 401 from affecting the stability of compression hemostasis during the hemostasis process during surgery. Example 3

[0021] Please see Figure 1 and Figure 8 and Figure 9 This invention provides a pressure hemostasis component for a hemostasis device used in hepatobiliary tumor surgery, the details of which are as follows: The hemostatic frame 7 is fixed to the lower end of the handle 3, and a pressure bag 8 is provided at the bottom of the hemostatic frame 7. The handle 3 is hollow, and a pipe is fixedly connected to the top outer wall of the handle 3 for controlling the introduction and export of gas in the pressure bag 8. The telescopic positioning rod 9 has its upper end hinged to the middle outer wall of the hemostatic frame 7, and the output shaft end of the telescopic positioning rod 9 is hinged to a pressure rod 10. The pressure rod 10 is in close contact with the positioning soft strip 11 on the bottom inner wall of the pressure bag 8. At the same time, a pressure adjustment component is provided at the hinge of the telescopic positioning rod 9 and the hemostatic frame 7 for limiting the angle and controlling the telescopic movement of the telescopic positioning rod 9. The side section of the positioning soft strip 11 is set as a "T" shaped structure, and the nodes at equal intervals at the beginning, end and middle sections of the positioning soft strip 11 are bonded and fixed to the inner wall of the pressure bag 8. The bottom of the entire positioning soft strip 11 is in contact with the bottom inner wall of the pressure bag 8. The pressure rod 10 is set between two parallel positioning soft strips 11, and the beginning and end of the pressure rod 10 are set as an "n" shape. The "n" end is in close contact with the outer wall of the positioning soft strip 11, and the middle section of the outer wall of the pressure rod 10 is in close contact with the bottom inner wall of the pressure bag 8. In the above technical solution, external gas is pressurized through pipes and external gas pressurization equipment and introduced into the pressure bag 8. The deformation and expansion of the pressure bag 8 directly achieves pressure hemostasis at the patient's wound site. At the same time, in order to improve the accuracy of pressure hemostasis and prevent the pressure bag 8 from being too large at the bottom, which would cause the external pressure to be dispersed and the hemostasis efficiency to be unstable, the telescopic positioning rod 9 is rotated. The telescopic positioning rod 9 moves through the position of the pressure rod 10 at its bottom, and works together with the positioning soft strip 11 to form a regional division of the pressure position at the bottom of the pressure bag 8. This allows the pressure bag 8 to adjust the pressure area at the bottom according to the size of the wound, making it convenient to operate and more stable in applying pressure hemostasis at the patient's wound site. Example 4

[0022] like Figures 10-14 As shown, based on Embodiment 3, the present invention specifically discloses a pressure adjustment component for controlling the rotation and limit of the telescopic positioning rod 9, the specific details of which are as follows: An electric telescopic rod 12 is fixed in the middle of the hemostatic frame 7. An adjusting push rod 13 is fixed at the output shaft end of the electric telescopic rod 12. The adjusting push rod 13 is slidably connected to the side of the hemostatic frame 7. The bottom of the adjusting push rod 13 is set with a strip-shaped sawtooth structure. The bottom of the adjusting push rod 13 is meshed with a gear ring 14. The gear ring 14 is fixed on the hinge shaft of the telescopic positioning rod 9 and the hemostatic frame 7. The adjusting push rod 13 is set with an "n" shaped structure. The middle part of the adjusting push rod 13 is fixedly connected to the electric telescopic rod 12 vertically. The "n" shaped corner node of the adjusting push rod 13 is set with a through movable setting. A pressure sensor 20 is set at its through point. The top of the hemostatic frame 7 is also fixed with a liquid cavity 15. A liquid sealing plate 16 is movably installed in the liquid cavity 15. An elastic element 17 is fixed between the liquid sealing plate 16 and the liquid cavity 15. A liquid guiding hose 18 is installed through the liquid cavity 15 and the telescopic positioning rod 9. An electric control valve 19 is fixed at the through point of the liquid guiding hose 18 and the telescopic positioning rod 9. The electric control valve 19 is electrically connected to the pressure sensor 20. The liquid sealing plate 16 and the liquid guiding hose 18 are arranged in a one-to-one correspondence. A sealed sliding connection is provided between the outer side of the liquid sealing plate 16 and the inner wall of the liquid cavity 15. A pressure vent is opened on the outer wall of the middle part of the liquid cavity 15. The electric telescopic rod 12 drives the adjusting push rod 13 to change its position, so that the adjusting push rod 13 directly meshes with the gear ring 14 during the movement, thereby causing the telescopic positioning rod 9 to deflect at an angle. During this process, the pressure sensor 20 at the node position of the adjusting push rod 13 receives the electrical signal of the pressure action, causing the electric control valve 19 to open. Utilizing the rotational push action of the telescopic positioning rod 9 and the oil pressure inside the liquid chamber 15, the telescopic positioning rod 9 extends and retracts synchronously. The extension and retraction of the telescopic positioning rod 9 can effectively avoid the impact of its length limitation on the hemostatic effect.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
