Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a painless push plug device for postoperative anorectal surgery. Background Technology
[0002] The painless suppository device is an essential instrument for postoperative drug administration in anorectal surgery. It delivers medication directly to the patient's site and is primarily used for rectal administration after minor anorectal surgeries such as hemorrhoid surgery. It mainly involves inserting hemorrhoid suppositories, greatly facilitating the administration of topical medications after anorectal surgery.
[0003] The existing technology has the following problems:
[0004] Currently, postoperative medication for anorectal surgery is usually administered manually by inserting the suppository into the postoperative site. However, some patients have thick fingers, making it difficult to insert the suppository due to its slippery nature. Furthermore, many hemorrhoid gels on the market are typically delivered to the postoperative site using a commonly used syringe. Because the gel has a large capacity, the syringes used are relatively thick, which doesn't adequately consider the possibility of postoperative wounds causing pain for the patient. Utility Model Content
[0005] This invention provides a painless push-button device for postoperative anorectal surgery to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A painless suppository device for postoperative anorectal surgery includes a suppository housing, a push rod disposed inside the housing, a piston fixedly mounted at the bottom of the push rod, a handle fixedly mounted at the top of the push rod, an auxiliary extension fixedly mounted on the upper part of the outer surface of the suppository housing, an inner liner fixedly mounted inside the housing, a specially elongated suppository placed inside the inner liner, and a thin film disposed at the bottom of the housing.
[0008] Preferably, the outer shell and inner lining of the painless push-button device are both thickened and made of food-grade PC material. The thickness of the inner lining is 2mm, and the inner surface of the inner lining is smoothed.
[0009] Preferably, the outer surface of the painless thrombectomy device housing is treated with an ultra-smooth surface, and the painless thrombectomy device housing is equivalent to a one-milliliter syringe.
[0010] Preferably, the handle is arc-shaped and made of food-grade PC material.
[0011] Preferably, a rubber ring is fixedly installed on the outer surface of the piston, and the piston is made of food-grade PC material, while the rubber ring is made of silicone.
[0012] Preferably, the push rod includes a piston rod, the bottom end of which is fixedly installed to the upper surface of the piston, and a connecting rod with a T-shaped cross-section is fixedly installed on the top of the piston rod. The top of the connecting rod is fixedly installed to the lower surface of the handle. The push rod is made of food-grade PC material.
[0013] Preferably, a cavity cap made of food-grade PC material is fixedly installed on the inner surface of the top of the painless push rod housing, and the inner surface of the cavity cap is slidably connected to the outer surface of the piston rod.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] 1. This utility model provides a painless suppository pusher for postoperative anorectal surgery. The outer surface of the suppository is treated with an ultra-smooth finish, and a specially designed, elongated suppository is placed inside the liner.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figures 1-6 As shown, a painless suppository device for postoperative anorectal surgery includes a painless suppository device housing 1, a push rod 3 is provided inside the painless suppository device housing 1, a piston 9 is fixedly installed at the bottom of the push rod 3, a handle 4 is fixedly installed at the top of the push rod 3, an auxiliary extension 5 is fixedly installed on the upper part of the outer surface of the painless suppository device housing 1, an inner liner 7 is fixedly installed inside the painless suppository device housing 1, a specially slender suppository 8 is placed inside the inner liner 7, and a thin film 2 is provided at the bottom of the painless suppository device housing 1.
[0026] The film 2 seals the outer shell 1 of the painless suppository applicator, eliminating the need for needles. To use, tear open the film 2, press the thumb on the handle 4, and hook the other fingers onto the sides of the auxiliary extension 5. Push the push rod 3 and piston 9 through the handle 4 to insert the specially designed, elongated suppository 8 (placed inside the liner 7) into the patient's medication site. This direct administration reduces contact between the patient's hands and the medication, lowering the risk of bacterial infection. It can be used for rectal administration after minor anorectal surgeries such as hemorrhoid surgery, avoiding the problem of slippery suppositories caused by thick fingers, which makes repeated insertion difficult.
[0027] like Figure 2 , Figure 3 , Figure 5 As shown, the outer shell 1 and inner lining 7 of the painless push-button device are both thickened and made of food-grade PC material. The inner lining 7 is 2mm thick and the inner surface of the inner lining 7 is smooth.
[0028] The outer shell 1 and inner liner 7 of the painless suppository device are thickened to prevent damage from drops and ensure durability. The inner surface of the inner liner 7 is smoothed for easy pushing and pulling and easy injection. The suppository 8 is directly administered by pushing the plunger 3, handle 4, and piston 9, reducing the patient's contact with the medication and lowering the risk of bacterial infection. It can be used for rectal administration after minor anorectal surgeries such as hemorrhoid surgery, avoiding the problem of the suppository being slippery due to the large size of the fingers, which makes it difficult for the patient to insert the suppository repeatedly.
[0029] like Figures 1-3 , Figure 5 , Figure 6 As shown, the outer surface of the painless thrombectomy device housing 1 is treated with an ultra-smooth surface, and the painless thrombectomy device housing 1 is equivalent to a one-milliliter syringe.
[0030] The painless push-button device housing 1 has an ultra-smooth outer surface, and the housing 1 is equivalent to a one-milliliter syringe, avoiding the pain caused to the patient by using a relatively thick drug delivery tool, thus taking care of the patient's user experience.
[0031] like Figures 1-4 As shown, the handle 4 is arc-shaped and made of food-grade PC material. A rubber ring 10 is fixedly installed on the outer surface of the piston 9. The piston 9 is made of food-grade PC material, and the rubber ring 10 is made of silicone.
[0032] The rubber ring 10 is installed to prevent the piston 9 from directly contacting the inner liner 7 and causing wear.
[0033] like Figures 2-6 As shown, the push rod 3 includes a piston rod 31. The bottom end of the piston rod 31 is fixedly installed on the upper surface of the piston 9. A connecting rod 32 with a T-shaped cross section is fixedly installed on the top of the piston rod 31. The top of the connecting rod 32 is fixedly installed on the lower surface of the handle 4. The push rod 3 is made of food-grade PC material. A cavity cap 6 made of food-grade PC material is fixedly installed on the inner surface of the top of the painless push rod device housing 1. The inner surface of the cavity cap 6 is slidably connected to the outer surface of the piston rod 31.
[0034] When the patient pushes the plunger 3 with the handle 4, the piston rod 31 can be guided by the cavity cap 6 to smoothly push the suppository 8 into the patient's medication site. At the same time, the cavity cap 6 can also seal the suppository and prevent foreign objects from falling into the suppository and causing contamination.
[0035] The working principle of this invention: A thin film 2 seals the outer shell 1 of the painless suppository, eliminating the need for a needle. The outer shell 1 functions as a one-milliliter syringe, avoiding the pain caused by using a relatively thick medication tool and achieving a painless effect. In use, the film 2 is torn open, the thumb presses on the handle 4, and the other fingers hook onto the sides of the auxiliary extension 5. The handle 4 pushes the plunger 3 and piston 9, inserting the specially slender suppository 8, placed inside the inner liner 7, into the patient's intended medication site. This direct administration reduces contact between the patient's hands and the medication, lowering the risk of bacterial infection. The painless suppository device features an ultra-smooth outer surface (1) to enhance the patient's experience, while the smooth inner surface (7) ensures smooth insertion and removal of the rubber ring (10) and piston (9). This allows for rectal administration after minor anorectal surgeries such as hemorrhoid surgery, avoiding the problem of slippery suppositories caused by thick fingers, which makes insertion difficult. The outer shell (1) and inner liner (7) are thickened and made of food-grade PC material, ensuring durability and preventing breakage from drops. A cap (6) provides a seal, preventing foreign objects from entering and contaminating the device.
[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
