Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an anorectal surgical cleaning and administering device. BACKGROUND

[0002] At present, when treating anorectal patients, an anorectal surgical cleaning and administering device is usually used. The anorectal surgical cleaning and administering device comprises a liquid storage bag and an administering tube. The liquid storage bag stores liquid medicine. The liquid medicine in the liquid storage bag is sent into the intestinal canal through the administering tube by squeezing the liquid storage bag, and is rapidly absorbed by the rectal mucosa to enter the general circulation to exert the medicinal effect to treat systemic or local diseases.

[0003] However, if too much liquid medicine is administered at one time, the liquid medicine flowing out of the administering tube will move from the intestinal canal to the stomach, causing anorectal patients to feel a sense of distending pain, causing discomfort. In addition, during the existing administering process, medical staff need to manually rotate the administering tube, which is easy to displace during rotation, resulting in an inability to accurately control the administering site, and displacement will also cause part of the liquid medicine to move to the stomach, causing a sense of distending pain. In addition, the condition of the diseased site and the treatment effect cannot be monitored in real time during the administering process, thereby affecting the treatment effect.

[0004] Therefore, there is an urgent need for an anorectal surgical cleaning and administering device that can accurately administer during the administering process and also avoid the flow of liquid medicine to the stomach to avoid the distending pain of anorectal patients. SUMMARY

[0028] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0029] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0030] This invention discloses a surgical cleaning and drug delivery device for anorectal surgery.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A surgical anorectal cleansing drug delivery device includes a reservoir 1, a drug delivery mechanism, a drive mechanism, and an anti-backflow mechanism. The reservoir 1 stores medication. The drug delivery mechanism has an outlet 2 for discharging the medication from the reservoir 1 through the outlet 2. The drug delivery mechanism includes a drug delivery head 3 and a drug delivery rod 4. The drug delivery rod 4 has an intermediate flow channel communicating with the reservoir 1 and the drug delivery head 3. The drug delivery head 3 can be driven to rotate relative to the drug delivery rod 4. The drive mechanism has a movable rod 6 that can be driven to drive the drug delivery rod 4 and the drug delivery device. The medication head 3 rotates. The anti-backflow mechanism includes a telescopic rod 15 and a rotating rod 16 rotatably mounted on the telescopic rod 15. Multiple rotating rods 16 are spaced circumferentially, and flexible connecting parts 17 are provided between adjacent rotating rods 16. The rotating rods 16 can be driven to open or retract, and the telescopic rods 15 can be driven to extend from or retract into the medication head 3. An air bladder is provided between the movable ends of the rotating rods 16 and the telescopic rods 15. The expansion or contraction of the air bladder causes the rotating rods 16 to expand or contract. The anti-backflow mechanism prevents the medication from moving towards the stomach, reduces turbulence, alleviates patient bloating and pain, and improves treatment comfort.

[0032] The reservoir 1 can be made of a hard material, such as alloy or metal, or a soft material, such as plastic. When made of a hard material, a liquid aspiration device is required to drain the liquid in the reservoir 1 into the drug delivery device. When made of a soft material, a liquid aspiration device is not required, and medical staff only need to press the reservoir 1.

[0033] In this embodiment, the reservoir 1 is made of rigid material and an electric liquid extraction device is installed in the drug delivery rod 4 to draw the drug liquid in the reservoir 1 into the drug delivery rod 4. The reservoir 1 can store glycerin suppositories, purified water, honey water or other drug liquids.

[0034] In this embodiment, the drug delivery rod 4 is detachably installed inside the reservoir 1. After the drug delivery rod 4 is removed, medical personnel can replenish or clean the reservoir 1. Specifically, the drug delivery rod 4 is threadedly connected to the reservoir 1.

[0035] The drug delivery rod 4 has a hollow structure formed by a central flow channel. A water delivery pipe is installed inside the drug delivery rod 4. The liquid in the reservoir 1 moves to the corresponding outlet 2 through the water delivery pipe. A main water delivery pipe is provided at the bottom of the drug delivery rod 4. The main water delivery pipe is connected to the liquid extraction device. (When the reservoir 1 is made of soft material, it flows directly with the reservoir 1.) The main water delivery pipe can rotate relative to the drug delivery rod 4. The outlet end of the main water delivery pipe is connected to multiple branch water delivery pipes. The branch water delivery pipes flow with the corresponding outlet 2. The drug liquid is discharged through the corresponding branch water delivery pipes and outlet 2.

[0036] In this embodiment, soft tentacles 21 are arrayed on the outer contour 112 of the administration rod 4. The soft tentacles 21 have a hardness close to that of the intestinal mucosa. The soft tentacles 21 can fully contact the anus and rectum to assist in scraping out residues or to stimulate and induce defecation.

[0037] In this embodiment, the drug delivery rod 4 is equipped with graduation lines, which facilitates precise drug administration by medical personnel. Furthermore, the drug delivery rod 4 is composed of multiple sub-rods, with adjacent sub-rods being detachably connected. By installing sub-rods of different numbers of sections, drug delivery rods 4 of different lengths can be formed to meet the treatment needs of anorectal patients with different requirements, improving applicability. In addition, it further improves the accuracy of drug administration. The design of the drug delivery rod 4 satisfies the needs of drug delivery, precise drug administration, and assisting in the handling of anorectal excretions, thereby improving the therapeutic effect.

[0038] In this embodiment, the topmost sub-rod is connected to the drug delivery head 3. The connection method can be a detachable connection or a fixed connection. When a detachable connection is used, different drug delivery heads 3 can be replaced, which improves applicability and also facilitates the cleaning and maintenance of the drug delivery head 3.

[0039] In this embodiment, the top of the administration head 3 has an arc-shaped transition for guiding the head of the present invention into the rectum. The circumferential inward depression of the administration head 3 forms a recess 22 for accommodating residues in the rectum.

[0040] The drug delivery mechanism also includes a movable tentacle 5 and a second driving mechanism. The movable tentacle 5 is rotatably mounted on the drug delivery rod 4 along its length. The second driving mechanism has a sliding rod 23, which drives the movable tentacle 5 to rotate. Medication is added to the reservoir 1 and then administered through the drug delivery mechanism. The first driving mechanism rotates the drug delivery rod and the drug delivery head 3, while the second driving mechanism rotates the movable tentacle 5. The movable tentacle 5 can scrape out any residue remaining in the rectum and anus, and clean it through the outlet 2. The rotation of the drug delivery head 3 and the movable tentacle 5 precisely controls the drug delivery site. Simultaneously, the movable tentacle 5 can prevent some of the medication from moving into the stomach, reducing the patient's bloating and pain.

[0041] In this embodiment, the movable tentacle 5 is mounted on the drug delivery head 3 in a rotating manner. The movable tentacle 5 has multiple flexible parts 20 that conform to the anal sinus. Each flexible part 20 also has a liquid outlet 2, which allows for simultaneous scraping and rinsing of anal and rectal residues. This not only makes the removal of residues smoother and more efficient but also cleans the movable tentacle 5, avoiding the need to clean it separately, thus saving surgical time and improving efficiency.

[0042] The flexible part 20 is provided with scrapers 19, which have an arc-shaped transition. The recesses 22 are located between the two scrapers 19. During the rotation of the movable tentacles 5, the residue is scraped into the recesses 22 and carried away from the rectum through the recesses 22, thereby cleaning the residue in the rectum and further improving the cleaning effect. In addition, during the later drug administration process, the scrapers 19 rotate with the movable tentacles 5 and can also massage the rectum, assisting the absorption of the drug solution and further improving the drug administration effect.

[0043] The flexibility of the flexible part 20 and the scraper 19 is close to that of the intestinal mucosa, which reduces the irritation to the anus and rectum.

[0044] An air bladder 14 is provided between the drug delivery rod 4 and the movable tentacle 5. The air bladder 14 can be driven to inflate or deflate. The expansion or contraction of the air bladder 14 can drive the movable tentacle 5 to rotate. The drug delivery rod 4 is equipped with a small air source, or it can be connected to an external air source. The air bladder 14 is located above and below the movable tentacle 5. When the movable tentacle 5 rotates away from the drug delivery head 3, the rotation angle can be adjusted by the lower air bladder 14. Similarly, when it rotates towards the drug delivery head 3, the rotation angle can be adjusted by the upper air bladder 14.

[0045] The second airbag section 14 allows the movable tentacle 5 to fit the rectum more closely, making cleaning and subsequent drug administration more efficient. The second airbag section 14 is elastic; compared to direct control using a rigid structure, using the second airbag section 14 to assist in adjusting the rotation angle is more comfortable and provides a better fit for the patient. It also requires less precision in motor control, avoiding excessive motor rotation that could cause rectal injury. The second airbag section 14 allows for large-angle rotation using the motor and small-angle rotation using the airbag, improving safety and comfort, making it more acceptable to patients. Furthermore, the second airbag section 14 can compensate for dimensional changes caused by rectal contraction or expansion due to stimulation, resulting in a gentler and more fitting fit, avoiding rectal irritation and providing greater comfort.

[0046] In this embodiment, the drive mechanism includes a moving rod 6, a central wheel 7, planetary gears 8, a gear ring 9, and a drive component. The planetary gears 8 mesh with the central wheel 7 and the gear ring 9 respectively. The gear ring 9 is coaxially fixedly mounted on the drug delivery rod 4. Multiple planetary gears 8 are spaced apart circumferentially. The central wheel 7 can be driven to rotate. The moving rod 6 is coaxially mounted on the planetary gears 8 and is fixedly connected to the drug delivery head 3. The drive component is used to drive the central wheel 7 to rotate. The drive component is a motor (not shown in the figure). The motor drives the central wheel 7 to rotate through a transmission structure, such as a bevel gear or a worm gear.

[0047] In this embodiment, the movable rod 6 is a hollow rod, and the water distribution pipe is coaxially arranged inside the movable rod 6 to deliver the medicine to the outlet 2. The outlet 2 of the uppermost sub-rod is connected to the water distribution pipe, while the outlet 2 of the non-rotating sub-rod is connected to the main water distribution pipe. This satisfies the simultaneous discharge of medicine from both rotating and non-rotating sub-rods, improving the cleaning and medication effects.

[0048] In this embodiment, the uppermost sub-rod is located within the projected area of ​​the movable tentacle 5. That is, when the anorectal surgical cleaning and dispensing device enters, the uppermost sub-rod will not directly contact the anorectum, thus avoiding direct contact between the sub-rod and the anorectum during rotation and preventing damage to the anorectum, thereby improving safety.

[0049] In this embodiment, the movable rod 6 can simultaneously drive the uppermost sub-rod, the drug delivery head 3, and the movable tentacle 5 to rotate, thereby achieving the initial anorectal cleaning and subsequent drug delivery. The reason for using only the rotation of a portion of the sub-rod is to avoid rotating the sub-rod at the anus, thus avoiding continuous friction at the anus, which could lead to anal damage or exacerbate patient discomfort.

[0050] The second driving mechanism includes a driving source 10, a rotating wheel 11, a crank 12, a slider 13, and a sliding rod 23. The slider 13 is axially slidably fitted inside the drug delivery rod 4, and the sliding rod 23 is rotatably fitted onto the sliding block. The driving source 10 is used to drive the rotating wheel 11 to rotate. In this embodiment, the driving source 10 is a motor. The crank 12 is eccentrically mounted on the rotating wheel 11 and rotatably connected to the slider 13. During the axial reciprocating movement of the sliding rod 23, the movable tentacles 5 are driven to rotate. One end of the sliding rod 23 is connected to the rotating rod 16 of the movable tentacles 5, and the other end is connected to the slider 13. The slider 13 moves axially, causing the sliding rod 23 to move axially, thereby driving the movable tentacles 5 to rotate up and down.

[0051] A bearing is coaxially mounted on the central wheel 7, and the sliding rod 23 slides axially through the bearing. The rotation of the central wheel 7 does not drive the bearing to rotate, but the bearing can rotate relative to the central wheel 7.

[0052] Furthermore, the rotating wheel 11 includes an inner wheel 111 and an outer wheel 112. The outer wheel 112 of the inner wheel 111 has a protrusion along its circumferential direction, and the inner wheel 111 of the outer wheel 112 has a recess that matches the protrusion along its circumferential direction. The protrusion and the recess cooperate with each other. The recess or the protrusion is made of an elastic material so that the recess can rotate relative to the protrusion. The drive source 10 is used to drive the inner wheel 111 to rotate.

[0053] The rotation of the central wheel 7 drives the planetary wheel 8 to rotate circumferentially. Since the moving rod 6 is located on the planetary wheel 8, it rotates synchronously. The water distribution pipe is located inside the moving rod 6 and also rotates synchronously. The moving rod 6 also drives the uppermost sub-rod to rotate synchronously. The uppermost sub-rod drives the drug delivery head 3 to rotate, and the movable tentacles 5 are located on the drug delivery head 3 and rotate synchronously. Therefore, the rotation of the central wheel 7 synchronously drives the uppermost sub-rod, drug delivery head 3, and movable tentacles 5 to rotate, completing the cleaning and drug delivery of the anus and rectum. The rotational drug delivery can perfectly cover the required drug delivery location in the anus and rectum, further improving the drug absorption effect. At the same time, the anorectal surgical cleaning drug delivery device of this invention also has the function of cleaning residues. The rotational function can also improve the effect of cleaning residues, avoiding residues remaining in the required drug delivery location in the anus and rectum, further ensuring the drug delivery effect.

[0054] The drug delivery head 3 is located under the armpit of the movable tentacle 5 and has a liquid outlet 2. The drug liquid is sprayed radially to improve the cleaning and lubrication effect. The flexible part 20 fully contacts the anorectal mucosa through reciprocating and rotating, accurately cleans the anal sinuses, scrapes out the residue remaining in the anorectal area, and fully stimulates the receptors in the anorectal area (such as intestinal wall stretch receptors, sensory nerve fibers of the external anal sphincter and internal anal sphincter) to induce the urge to defecate and thus facilitate defecation.

[0055] To facilitate medical staff's observation of the internal condition of the rectum, a camera 18 is installed at the top of the telescopic rod 15. The telescopic rod 15 can be electrically operated and retracted.

[0056] In this embodiment, a control system is also included. The control system is used to control the start and stop of the drive mechanism one and the drive mechanism two and the speed of the corresponding motors, and to inflate and de-inflate the airbag part two 14. The control system may also have a wireless communication system for wirelessly controlling the anorectal surgical cleaning and dispensing device of the present invention. The control system uses a CPU and its peripheral circuits.

[0057] The anorectal surgical cleaning and dispensing device of the present invention can provide anorectal patients with safe defecation, anal sinus cleaning and defecation urge induction, precise drug delivery and anal canal maintenance. It is convenient and easy to use, can be reused, has a high utilization rate, and has excellent cleaning effect.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. The above descriptions are only preferred embodiments of the present invention. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes, or combinations, or the direct application of the inventive concept and technical solution to other situations without modification, should all be considered within the scope of protection of the present invention.
