Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a postoperative analgesia and hemostasis device for anorectal surgery. Background Technology

[0002] Anorectal diseases, such as hemorrhoids, anal fistula, and anal fissure, are common and frequently occurring conditions in clinical practice. Surgical treatment is the primary means of curing these diseases. However, postoperative wound care and recovery are crucial aspects of the entire treatment process, directly impacting the surgical outcome and the patient's recovery period. The core tasks of postoperative wound care typically include local administration of medication to achieve analgesia, hemostasis, infection control, and promote healing.

[0003] In current clinical practice, the administration of medication to postoperative wounds in anorectal surgery mainly relies on the assistance of medical staff or family members. This routine procedure usually involves using fingers, cotton swabs, or simple administration tubes to directly apply or inject ointments, suppositories, or liquids into the wounds inside the patient's anal canal and rectum.

[0004] Although this traditional method of drug administration is widely used in clinical practice, its inherent operational mode brings many inconveniences and troubles to patients. This method relies entirely on the intervention of external personnel, making it impossible for patients to independently complete the drug administration procedure during the special postoperative period. This dependence on others not only reduces the convenience of the drug administration process, requiring patients to cooperate with the working hours of medical staff or seek help from family members, but more importantly, due to the special nature of the treatment site, having someone else perform the drug administration inevitably infringes on the patient's privacy, easily leading to embarrassment, tension, or even resistance, which may affect treatment compliance and efficacy. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a postoperative analgesia and hemostasis device for anorectal surgery, which solves the problem that existing technologies are significantly insufficient in meeting patients' needs for autonomy, convenience, and privacy protection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a postoperative analgesia and hemostasis device for anorectal surgery, comprising a working box mounted on the top of a base, a sponge pad mounted on the top of the working box, a rocker arm rotatably connected to one end of the working box, a worm gear fixedly connected to one end of the rocker arm, multiple worm wheels rotatably connected to the inner wall of the working box, the worm gear meshing with the multiple worm wheels, a positioning pin threadedly connected to the inner wall of one of the worm wheels, a drug delivery tube fixedly connected to the top of the positioning pin, a medicine tank inside the working box, a liquid delivery tube mounted on one end of the tank, and an analgesia component mounted on one end of the working box after pressurization by a pressurizing component to connect the liquid delivery tube with multiple delivery grooves opened on the inner wall of the drug delivery tube.

[0007] According to the above technical solution: when the patient rotates this rocker arm, the worm gear fixedly connected to it rotates accordingly, and through meshing transmission, synchronously drives multiple worm wheels on the inner wall of the working box. One of the worm wheels, through the threaded structure on its inner wall, converts the rotational motion into linear vertical displacement of the positioning column and the drug delivery tube fixed at its top. This design allows the patient to autonomously, slowly, and precisely control the depth of the drug delivery tube entering the wound. At the same time, the rotation of the rocker arm also continuously mechanically pressurizes the internal medicine tank through the pressurization component. The pressurized medicine is delivered to the drug delivery tube through the delivery tube and sprayed out from multiple delivery slots opened on its inner wall. By fully integrating the two core functions of depth positioning of the drug delivery tube and pressurized spraying of the medicine into a single control component, the rocker arm, the patient can independently complete the entire postoperative medication, analgesia, and hemostasis treatment process without any external assistance, simply by sitting and using a simple hand rotation. This improves the convenience of postoperative care while effectively protecting the patient's privacy during the treatment process.

[0008] Preferably, the pressurizing component includes a pulley assembly, which is installed at one end of a rocker arm and the other end is connected to a turntable installed inside the working box. A pull rod is installed on the outside of the turntable, and a piston is rotatably connected to one end of the pull rod. A pressure box is fixedly connected inside the working box, and an air inlet pipe and an air delivery pipe are respectively installed at both ends of the pressure box.

[0009] Preferably, a heating plate is installed at the bottom of the medicine tank, a power supply is provided on one side of the heating plate, and a switch valve is installed at one end of the medicine tank.

[0010] Preferably, the analgesic component includes a turbofan, which is fixedly connected to the top of one of the worm gears. A stirring blade is fixedly connected to the bottom of the turbofan. An air duct is provided on one side of the inner wall of the working box, and an air delivery pipe is provided at one end of the air duct. The air delivery pipe passes through the medicine tank and is connected to the inside of the medicine delivery pipe.

[0011] Preferably, both the liquid delivery pipe and the gas delivery pipe are made of flexible deformable material.

[0012] Preferably, the air delivery pipe passes through the positioning column and communicates with the air delivery groove in the inner wall of the drug delivery pipe, using the airflow heated by the temperature inside the medicine tank to assist in analgesia.

[0013] Preferably, the upper surface of the working box has a hole, and a sealing ring is fixedly connected inside the hole. A drug delivery pipe is slidably connected inside the sealing ring. When the liquid delivery tank is less covered by the sealing ring, its spraying pressure is higher, and when the liquid delivery tank is more covered by the sealing ring, its spraying pressure is lower.

[0014] Preferably, one-way valve one and one-way valve two are installed at both ends of the gas supply pipe, respectively, for pressurizing the inside of the medicine tank.

[0015] Preferably, the pulley assembly includes multiple pulleys connected externally by a belt, with one pulley mounted on the rear side of the turntable and another mounted on the outer wall of the rocker arm.

[0016] Preferably, the piston is slidably connected to the inner wall of the pressure chamber, and the air inlet pipe and the air delivery pipe are arranged diagonally.

[0017] Working principle: When performing postoperative care, the user first places the device on a stable surface and sits down according to the preset contour on the sponge pad, aligning the affected area with the center hole of the device to achieve initial positioning. Then, the power is turned on, allowing the heating plate at the bottom of the medicine tank to heat the internal medicine solution until it reaches the preset constant temperature.

[0018] When the device is in operation, the user manually rotates a lever located on one side of the work box. The rotation of this lever simultaneously drives two independent mechanical functions: First function for drug delivery and depth control: The rotation of the rocker arm drives one of the worm gears to rotate via a worm. This worm gear, through its internal threads, converts its rotational motion into a linear reciprocating motion with the positioning post. Since the medication delivery tube is fixedly connected to the positioning post, it moves smoothly up or down, thus achieving precise control over the depth of insertion into the affected area.

[0019] Simultaneously, the rotation of the rocker arm drives the turntable to rotate via a pulley assembly. The turntable, through its eccentrically connected rod, drives the piston to reciprocate within the pressure chamber. This process draws in and compresses external air. The resulting compressed air, constrained by one-way valves one and two, is pumped unidirectionally into the medicine tank, continuously pressurizing the medication. When the pressure inside the medicine tank reaches a preset value, the medication is delivered through the delivery pipe to the medicine delivery tube and sprayed out from multiple delivery slots on its outer wall, achieving drug administration and analgesia / hemostasis at the affected area.

[0020] As the delivery tube moves upward, the liquid delivery grooves on its outer wall gradually move out of the shielding area of ​​the sealing ring at the top of the working chamber. With the internal pressure of the medicine tank remaining constant, the total spray outlet area increases as the number of exposed liquid delivery grooves increases, thus reducing the spray pressure accordingly. This structure achieves dynamic adjustment where the spray pressure is negatively correlated with the penetration depth. Furthermore, by replacing the pull rods of different lengths, the piston stroke can be adjusted, thereby regulating the amount of air pumped per cycle and allowing for the preset of the maximum pressurization within the medicine tank.

[0021] Second auxiliary analgesia and constant temperature function of the drug solution: The rotation of the rocker arm also drives another worm gear to rotate via a worm. This worm gear synchronously drives the turbine fan mounted above it and the stirring blade below to rotate together. The rotation of the stirring blade enables forced convection of the liquid in the medicine tank, ensuring that the heat generated by the heating plate is evenly distributed throughout the liquid, eliminating temperature gradients, and ensuring a constant temperature of the sprayed liquid.

[0022] Simultaneously, the turbine fan's rotation draws in outside air through the duct and delivers it along the air delivery pipe. This pipe runs through the inside of the medicine tank, allowing the airflow to fully exchange heat with the external, temperature-controlled medicine solution as it flows through this section, thus raising the airflow temperature. The heated airflow continues along the air delivery pipe, passing through the positioning column, and finally exits from the air delivery slot on the outer wall of the pipe. This warm airflow significantly reduces the irritation to the affected area during medicine spraying, aiding in pain relief.

[0023] Furthermore, because the air delivery tube, air duct, and air delivery slot form a physically connected air passage, this passage remains open even when the turbofan stops rotating. This design effectively prevents the formation of a closed cavity at the affected area when the delivery tube is accidentally blocked or compressed, thus preventing pressure buildup and discomfort such as bloating.

[0024] This invention provides a postoperative analgesia and hemostasis device for proctology. It has the following beneficial effects: 1. This invention, through the combined use of components such as a pressure box, piston, drug delivery tube, and rocker, enables patients to administer postoperative medication, pain relief, and hemostasis independently, improving convenience while ensuring patient privacy during device use.

[0025] 2. By using components such as heating plates, turbine fans, and stirring blades in combination, this invention can control the spray pressure of the medicine during use by utilizing pressure differences, and is also equipped with constant temperature airflow assistance, thereby reducing the foreign body sensation of the device, improving the analgesic effect and enhancing the comfort of the user.

[0026] 3. By using components such as a turntable, a one-way valve, and an air supply pipe in combination, this invention can significantly reduce the use of electrical components and improve the safety of the device. Attached Figure Description

Detailed Implementation

[0029] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a postoperative analgesia and hemostasis device for proctology, comprising a working box 2 mounted on top of a base 1, a sponge pad 3 mounted on the top of the working box 2, a rocker arm 4 rotatably connected to one end of the working box 2, a worm gear 5 fixedly connected to one end of the rocker arm 4, and multiple worm wheels 6 rotatably connected to the inner wall of the working box 2, with the worm gear 5 meshing with the multiple worm wheels 6. A positioning post 7 is threadedly connected to the inner wall of one of the worm wheels 6, and a drug delivery tube 9 is fixedly connected to the top of the positioning post 7. A medicine tank 10 is provided inside the working box 2, with a liquid delivery tube 20 installed at one end. After being pressurized by a pressurizing component, the liquid delivery tube 20 communicates with multiple liquid delivery grooves 25 opened on the inner wall of the drug delivery tube 9. An analgesia component is provided at one end of the working box 2. Both the liquid delivery tube 20 and the air delivery tube 21 are made of flexible deformable material. The upper surface of the working box 2 has holes, and a sealing ring 8 is fixedly connected inside the holes. A drug delivery pipe 9 is slidably connected inside the sealing ring 8. When the liquid delivery tank 25 is less covered by the sealing ring 8, its spraying pressure is higher. When the liquid delivery tank 25 is more covered by the sealing ring 8, its spraying pressure is lower.

[0031] Specifically, its basic structure consists of a base 1 and a hollow working box 2 fixed on top of it. The base 1 provides stable physical support for the entire device, and the upper surface of the working box 2 is covered with an ergonomically designed sponge pad 3. The sponge pad 3 has a through hole in the center for the user to maintain a sitting posture after surgery and provides an extension channel for the internal drug delivery tube 9.

[0032] The user manually operates the rocker arm 4 located on one side of the working box 2 to start the device. A worm gear 5 is fixedly connected to the inner end of the rocker arm 4. The thread of the worm gear 5 meshes with two worm wheels 6 installed on the inner wall of the working box 2.

[0033] This transmission achieves two functions: Firstly, precise linear displacement of the delivery tube 9 is achieved. One of the worm gears 6 has a threaded inner wall in its central hole, which meshes with the external thread of the positioning pin 7. The top of the positioning pin 7 is fixedly connected to the base of the delivery tube 9. When the rocker arm 4 is rotated, the worm gear 5 drives the worm gear 6 to rotate. Through the transmission principle of the threaded pair, the rotational motion of the worm gear 6 is converted into the smooth upward or downward motion of the positioning pin 7 and the delivery tube 9 along the vertical axis. This structure allows for precise control of the insertion depth of the delivery tube 9.

[0034] Secondly, it provides a power source for the analgesia component. The worm gear 5 drives another worm wheel 6 to rotate synchronously. The power output of the worm wheel 6 can be used to drive other components such as the turbofan 22, realizing multi-functional mechanical linkage.

[0035] The drug delivery system begins with a drug tank 10 located inside the working chamber 2. The drug tank 10 is connected to the liquid channel inside the drug delivery tube 9 via a delivery pipe 20 made of a flexible deformable material. The flexible material is used to accommodate the relative positional changes that occur when the drug delivery tube 9 undergoes vertical displacement. When the pressurizing component applies pressure to the drug solution inside the drug tank 10, the solution is pumped through the delivery pipe 20 to the liquid channel inside the drug delivery tube 9, and finally ejected from multiple delivery slots 25 formed on the outer wall of the drug delivery tube 9.

[0036] A flexible sealing ring 8 is fixed inside a through-hole at the top of the working chamber 2, and the drug delivery tube 9 slides within the inner hole of the sealing ring 8. At its initial lowest position, all the delivery grooves 25 on the outer wall of the drug delivery tube 9 are located below the sealing ring 8 and are physically shielded by it. As the drug delivery tube 9 moves upward, the delivery grooves 25 slide out of the shielding range of the sealing ring 8 one by one. According to the principles of fluid dynamics, when only a few delivery grooves 25 are exposed, the total spray outlet area is minimized, thus generating a larger spray pressure under the same internal pressure; as the number of exposed delivery grooves 25 increases, the total spray outlet area increases, and the spray pressure decreases accordingly. This design achieves a negative correlation between spray pressure and penetration depth, aiming to provide powerful cleaning upon initial contact and transition to gentle spraying as it penetrates deeper into sensitive areas, reducing discomfort and adapting to the needs of different treatment stages.

[0037] Please see the appendix Figure 4 -Appendix Figure 6The pressurization assembly includes a pulley assembly 13, which is mounted on one end of a rocker arm 4 and connected at the other end to a turntable 14 installed inside the working chamber 2. A pull rod 18 is mounted on the outside of the turntable 14, and a piston 28 is rotatably connected to one end of the pull rod 18. A pressure chamber 12 is fixedly connected inside the working chamber 2, and an air inlet pipe 19 and an air delivery pipe 17 are respectively mounted on both ends of the pressure chamber 12. One-way valve 15 and one-way valve 16 are respectively installed on both ends of the air delivery pipe 17 for pressurizing the medicine tank 10. The pulley assembly 13 includes multiple pulleys connected externally by a belt. One pulley is mounted on the rear side of the turntable 14, and another is mounted on the outer wall of the rocker arm 4. The piston 28 is slidably connected to the inner wall of the pressure chamber 12, and the air inlet pipe 19 and the air delivery pipe 17 are diagonally arranged.

[0038] Specifically, inside the working box 2, the driving pulley of the pulley assembly 13 is fixedly installed on the outer wall of the rocker arm 4. This driving pulley is connected to the driven pulley mounted on the rotating shaft of the turntable 14 via a ring belt. This structure stably transmits the manual rotational motion of the rocker arm 4 to the turntable 14, driving it to rotate around its own central axis.

[0039] On the surface of the turntable 14, a tie rod 18 is rotatably connected to a position off-center from its rotation center via a pin. The other end of the tie rod 18 is rotatably connected to the pin seat of the piston 28. The outer periphery of the piston 28 forms a tight sliding fit with the inner wall of the pressure chamber 12 fixed inside the working chamber 2. This crank-connecting rod mechanism, consisting of the turntable 14, the tie rod 18, and the piston 28, converts the continuous rotational motion of the turntable 14 into the reciprocating linear motion of the piston 28 within the cylindrical cavity of the pressure chamber 12.

[0040] The pressure chamber 12 serves as the cylinder of the air pump, with an inlet pipe 19 and an outlet pipe 17 diagonally arranged at both ends. When the reciprocating motion of the piston 28 causes the volume of one side of its cavity to increase, a negative pressure is created in that cavity, and external air is drawn into the pressure chamber 12 through the inlet pipe 19. When the piston 28 moves in the opposite direction, causing the volume of that cavity to decrease, the internal air is compressed. The compressed air is discharged through the outlet pipe 17.

[0041] On the gas supply pipe 17, one-way valve 15 and one-way valve 16 are installed in series. The function of these two valves is to establish a one-way airflow channel, that is, to allow air to flow from pressure tank 12 to medicine tank 10, and to prevent any gas from flowing back from medicine tank 10 to pressure tank 12.

[0042] Therefore, as the user continuously rotates the rocker arm 4, the piston 28 continuously cycles between intake and compression. The compressed air generated by each compression stroke is continuously pumped into the top space of the medicine tank 10 under the constraint of the one-way valve assembly, thereby establishing a stable pressure inside for spraying the medicine.

[0043] Please see the appendix Figure 3 Appendix Figure 5 A heating plate 26 is installed at the bottom of the medicine tank 10, and a power supply is provided on one side of it. A switch valve 11 is installed at one end of the medicine tank 10.

[0044] Specifically, to achieve temperature control of the liquid medicine, an electric heating plate 26 is fixedly installed on the outer bottom surface of the medicine tank 10. This heating plate 26 is connected to a power source located outside the working chamber 2 via internal wires. Its function is to convert the input electrical energy into heat energy and heat the base of the medicine tank 10 through direct contact. The heat is then conducted to the liquid medicine inside the tank, raising its temperature and maintaining it at a constant preset value.

[0045] In addition, a manually operated switch valve 11 is installed at one end of the medicine tank 10. This switch valve 11 functions as a sealable port. Before use, the operator can open this valve to inject medicine into the medicine tank 10. During operation, the switch valve 11 is closed to ensure the complete sealing of the medicine tank 10. This sealing is a physical prerequisite for the pressurization assembly to establish and maintain effective injection pressure inside the tank. After use, the valve can be reopened to drain residual liquid and perform internal cleaning.

[0046] Please see the appendix Figure 5 -Appendix Figure 7 The analgesic component includes a turbine fan 22, which is fixedly connected to the top of one of the worm gears 6. A stirring blade 23 is fixedly connected to the bottom of the turbine fan 22. An air duct 27 is provided on one side of the inner wall of the working chamber 2, and an air supply pipe 21 is provided at one end of the air duct 27. The air supply pipe 21 passes through the medicine tank 10 and connects to the inside of the medicine delivery pipe 9. The air supply pipe 21 passes through the positioning post 7 and communicates with the air supply groove 24 in the inner wall of the medicine delivery pipe 9, utilizing the heated airflow inside the medicine tank 10 to assist in analgesia.

[0047] Specifically, the power of this component comes directly from another worm wheel 6 that meshes with the main drive worm 5. A turbo fan 22 is vertically fixed to the top of this worm wheel 6, and a stirring blade 23 is coaxially fixed to its bottom. Both the turbo fan 22 and the stirring blade 23 are located inside the medicine tank 10. When the user turns the rocker arm 4, the worm 5 drives the worm wheel 6 to rotate, thereby synchronously driving the turbo fan 22 and the stirring blade 23 to rotate.

[0048] The stirring blade 23 functions to generate convection in the liquid inside the medicine tank 10. This process ensures that the heat generated by the bottom heating plate 26 can be evenly distributed throughout the entire volume of the medicine, thereby eliminating the temperature gradient inside the liquid and ensuring the uniformity of the medicine temperature.

[0049] Meanwhile, the rotation of the turbofan 22 generates negative pressure, drawing in outside air through the air duct 27 formed in the inner wall of the working chamber 2 and introducing it into an air supply pipe 21. This air supply pipe 21 is designed to run horizontally through the entire interior of the medicine tank 10, ensuring it is completely submerged in the heated medicinal liquid. When room temperature air flows through this pipe, it exchanges heat with the higher-temperature medicinal liquid outside the pipe via the pipe wall, thereby raising the temperature of the airflow inside the pipe.

[0050] The heated airflow continues to be delivered along the air delivery pipe 21, passing through the central channel of the positioning column 7 in sequence, and finally entering and connecting to the special air delivery slot 24 opened on the inner wall of the medicine delivery pipe 9.

[0051] Therefore, when the device sprays medication onto the affected area, the medication pipe 9 sprays not only the constant-temperature medication from the liquid delivery tank 25, but also a warm airflow from the air delivery tank 24 that is at a similar temperature to the medication. The physical function of this warm airflow is to reduce the thermal stimulation that the temperature difference may cause to sensitive tissues after surgery when the medication is sprayed, thereby assisting in achieving an analgesic effect.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
