Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a post-operative analgesia and hemostasis device for anorectal surgery. Background Art

[0002] After anorectal surgery (such as hemorrhoidectomy, anal fistula hanging surgery, etc.), the patient's anus and anorectal inner wall will have surgical wounds. The wounds caused by anorectal surgery have certain particularities, with a high risk of contamination, dense nerve endings, and easy bleeding. Therefore, the management of postoperative pain and bleeding directly affects the quality of patient recovery.

[0003] The postoperative treatment device in the prior art mainly fills the patient's wound with medical gauze to stop bleeding, and sprays analgesic and anti-inflammatory drugs on the wound to reduce the patient's discomfort; however, since the size of the treatment device is fixed and cannot be adjusted, when it is inserted into the patient's anus and rectum to treat the wound inside the patient's anus and rectum, it is very easy to cause discomfort to the patient's anus and rectum due to its excessive size, or even cause secondary damage to the patient's anus and rectum.

[0004] In summary, solving the problem of the fixed size and inability to adjust the postoperative treatment device in the prior art, which affects the treatment effect, has become a difficult problem that needs to be solved in the current field. Therefore, it is necessary to propose a more reasonable analgesic and hemostatic device for anorectal surgery. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides an anorectal surgery postoperative analgesia and hemostasis device. Through the design of the support component, the size of the device can be conveniently adjusted so that the device can adapt to different patients, improve the patient's comfort during anorectal postoperative care, and improve the postoperative care effect.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: A post-operative analgesia and hemostasis device for anorectal surgery includes a controller and a driving member, a threaded rod is coaxially fixedly connected to the output shaft of the driving member, and the controller is used to control the operation of the driving member, thereby driving the threaded rod to rotate; the threaded rod rotates in sequence along a direction away from the driving member to be equipped with a medicine storage sleeve for storing medicine, a threaded sleeve and a waste liquid tank for storing waste liquid.

[0007] The threaded sleeve is provided with a supporting component for supporting the inner wall of the patient's anus, a spraying component for spraying liquid medicine, and a suction component for sucking waste liquid; the driving member is provided with an expansion component for expanding the patient's anus.

[0008] The support assembly includes a first hinged rod circumferentially hinged on the outer wall of the threaded sleeve, and the first hinged rod is hinged to an elastic support plate at one end away from the threaded sleeve; the support plate is hinged to a second hinged rod at one end away from the first hinged rod, and the second hinged rod is hinged to the outer wall of the medicine storage sleeve at one end away from the support plate; the side walls of the first hinged rod are hinged to the side walls of the second hinged rod adjacent to it; and a wearing assembly is provided on the driving member for facilitating the patient to wear the device conveniently.

[0009] The technical principles of the above scheme are as follows:

[0010] In the initial state, the support plates are close to each other. At this time, the overall size of the device is the smallest, and the medical staff inserts the threaded rod and the support plate into the patient's anus and rectum; after the insertion is completed, the driving part is started by the controller, and the driving part drives the threaded rod to rotate, so that the threaded sleeve slides along the threaded rod, and then drives the first hinged rod and the second hinged rod to rotate away from the threaded sleeve. At this time, the first hinged rod and the second hinged rod will drive the support plate away from the threaded sleeve, thereby expanding in the patient's anus and rectum to adapt to anorses of different diameters until it fits with the inner wall of the patient's anus and rectum. The driving part is stopped, and the spray component is used to spray the medicine into the patient's anus and rectum, and the pus and excess medicine in the patient's anus and rectum are sucked out by the suction component.

[0011] The above scheme has the following beneficial effects:

[0012] 1. The postoperative treatment devices in the prior art are often of fixed size and cannot be adjusted. Although they can stop bleeding and relieve pain in the patient's anorectal region, they are also prone to cause discomfort to the patient and may even cause secondary damage to the patient's anorectal region. Unlike the prior art, the present invention can conveniently adjust the position of the support plate through the design of the first hinged rod and the second hinged rod, so that the device maintains a minimum size when inserted into the patient's anorectal region, facilitating its insertion into the patient's anorectal region, reducing discomfort after postoperative treatment, and avoiding secondary damage to the patient. At the same time, after the insertion is completed, the support plate can be fitted with the patient's anorectal region to support the patient's anorectal region, facilitating subsequent postoperative treatment of the patient's anorectal region.

[0013] 2. The postoperative treatment devices in the prior art may require the selection of devices of different sizes according to the patient's body shape in order to perform relatively comfortable postoperative treatment. Unlike the prior art, the present invention can dynamically adjust the position of the support plate through the design of the support plate, so that the entire device can adapt to patients of different body shapes, improve the comprehensiveness of anorectal postoperative treatment, and reduce the patient's pain.

[0014] 3. Since the existing technology cannot freely adjust its own size, it is often necessary to prepare equipment of multiple sizes, so that patients of different body sizes can use equipment of different sizes for postoperative treatment; this method greatly increases medical costs and equipment preparation costs; compared with the existing technology, the present invention can freely adjust its own size, thereby significantly reducing medical costs and equipment preparation costs.

[0015] Furthermore, an annular medicine storage chamber is opened inside the medicine storage sleeve; the spray assembly includes a piston ring that slides laterally in the medicine storage chamber, and a plurality of first piston rods are fixedly connected to the side of the piston ring close to the threaded sleeve, and the ends of the first piston rods away from the piston ring are fixedly connected to the threaded sleeve; a plurality of through holes are opened on the medicine storage sleeve.

[0016] Beneficial Effect: When the threaded sleeve slides along the threaded rod, it simultaneously drives the first piston rod, which in turn pushes the piston ring to slide horizontally within the medicine storage chamber, thereby discharging the liquid medicine from the through-hole. This structural design links the spraying of the liquid medicine with the movement of the threaded sleeve, achieving an automatic spraying function, eliminating the need for a complex spray drive device and simplifying the structure and operation of the device.

[0017] Furthermore, the support plates are hollow inside and are connected to medicine delivery pipes; the medicine delivery pipes are connected to the through holes adjacent to them, and the connection points between the two are connected to control valves; the controller is used to control the operation of the control valves, thereby controlling the flow of the medicine liquid; and a number of medicine discharge holes are opened on the side walls of the support plates.

[0018] Beneficial Effects: By opening the control valve via a controller, the drug solution flows from the through-holes in the drug storage chamber through the drug delivery tubes to each support plate. Because the support plates are in direct contact with the patient's anorectal lining, the drug solution can be precisely sprayed onto the anorectal lining through the drug discharge holes on the support plate sidewalls, enhancing the therapeutic effect.

[0019] Furthermore, a piston plate is provided in the waste liquid tank for transverse sliding engagement, and a plurality of second piston rods are fixedly connected to the side of the piston plate close to the threaded sleeve, and the ends of the second piston rods away from the piston ring are fixedly connected to the threaded sleeve; a plurality of suction holes are provided on the waste liquid tank, and the suction holes are all connected to a one-way valve for allowing waste liquid to flow into the waste liquid tank.

[0020] Beneficial Effects: When the threaded sleeve slides along the threaded rod, it simultaneously drives the second piston rod, which in turn pushes the piston plate to slide horizontally within the waste liquid tank, thereby aspirating pus and excess medication from the patient's anus and rectum into the waste liquid tank, improving the efficiency and timeliness of waste liquid aspiration. The one-way valve only allows waste liquid from the patient's anus and rectum to flow into the waste liquid tank, preventing waste liquid from flowing back into the patient's anus and rectum. This effectively avoids the risk of infection caused by waste liquid backflow, ensures the cleanliness and hygiene of the patient's anus and rectum, and promotes the healing of postoperative wounds.

[0021] Furthermore, the waste liquid tank is detachably connected to an elastic arc-shaped head at one end away from the threaded rod.

[0022] Beneficial effect: When the threaded rod is inserted into the patient's anus and rectum, the arc-shaped head has a good guiding effect compared to the flat end of the threaded rod, so that the threaded rod and the support plate can be better inserted into the patient's anus and rectum.

[0023] Furthermore, the expansion component includes a rotating plate coaxially fixedly connected to the output shaft of the driving member, and the rotating plate is symmetrically hinged with an arc strip on one side close to the driving member, and the arc strip is hinged to a limit rod at the other end away from the rotating plate, and the limit rod is fixedly connected to an elastic block for expanding the patient's anus at one end away from the arc strip; a limiting component for limiting the moving direction of the elastic block is provided on the driving member.

[0024] Beneficial effects: After the threaded rod and the support plate are inserted into the patient's anus and rectum, the elastic block will contact the patient's anus; when the driving part drives the rotating plate to rotate, the arc strip will push the limit rod to move, thereby driving the elastic blocks away from each other, and driving the skin and muscles around the patient's anus away from each other, thereby expanding the patient's anus. At the same time, the support plate will synchronously expand the inner wall of the patient's anus and rectum, so that the patient's anus and the inner wall of the anus and rectum expand synchronously. This synchronous expansion method can simulate the natural physiological expansion process of the human body, improve the patient's muscle coordination and the comfort of treatment.

[0025] Furthermore, the limiting assembly includes a slide rail fixedly connected to the driving member; the slide rail is located between the rotating plate and the driving member, and the limiting rods are in transverse sliding cooperation with the slide rail.

[0026] Beneficial effects: When the driving member drives the rotating plate to rotate, the sliding of the limit rod in the slide rail is restricted by the slide rail, and the limit rod will drive the elastic block to slide along both sides of the slide rail, thereby expanding the patient's anal area. At the same time, the slide rail prevents the elastic block from offsetting or shaking during movement, thereby improving the accuracy and stability of the expansion.

[0027] Furthermore, the side walls of the slide rails are symmetrically fixedly connected to medicine storage boxes, and medicine pushing plates are laterally slidably fitted inside the medicine storage boxes; medicine pushing rods are hinged on the side of the medicine pushing plates close to the driving member, and the ends of the medicine pushing rods away from the medicine pushing plates are hinged to the limit rods adjacent to them; the medicine storage boxes are connected to the elastic blocks adjacent to them, and the elastic blocks are also provided with a number of medicine holes.

[0028] Beneficial effect: When the limit rod slides in the slide rail, the limit rod will synchronously drive the medicine pushing rod to move, and then push the medicine pushing plate box to slide horizontally in the medicine storage box, and then spray the medicine liquid in the medicine storage box to the patient's anus through the medicine discharge hole. Moreover, since the elastic block fits the patient's anus, the medicine liquid can be sprayed on the patient's skin surface more reasonably.

[0029] Furthermore, the wearable component includes a belt, both ends of the belt are fixedly connected to magnetic blocks, the bottom of the belt is fixedly connected to a connecting strip, and the bottom of the connecting strip is fixedly connected to the side of the driving member away from the slide rail.

[0030] Beneficial effects: The patient can wear the belt around the waist and fix it with a magnetic block. After the threaded rod and support plate are inserted into the patient's anorectal area, the connecting strip will provide traction and support for the driving part, reducing the burden on the patient's anorectal area, making it easier for the patient to wear the device conveniently, and improving the comfort and convenience of treatment.

[0031] Furthermore, the support plates are all arranged at an inclination.

[0032] Beneficial effect: When the support plate is inserted into the patient's anus and intestine, the inclined support plate can gradually expand the patient's anus and intestine, thereby more smoothly inserting the support plate into the patient's anus and intestine, reducing the patient's discomfort.

[0033] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is further described in detail through specific implementation methods:

[0042] Example 1:

[0043] As attached Figures 1-6 As shown: A post-operative analgesia and hemostasis device for anorectal surgery includes a controller and a driving member, a threaded rod 2 is fixedly connected to the output shaft of the driving member with a coaxial bolt, and the controller is used to control the operation of the driving member, thereby driving the threaded rod 2 to rotate; the threaded rod 2 rotates in sequence in a direction away from the driving member to be equipped with a medicine storage sleeve 3 for storing medicine liquid, a threaded sleeve 4 and a waste liquid tank 5 for storing waste liquid.

[0044] The threaded sleeve 4 is provided with a supporting component for supporting the inner wall of the patient's anus, a spraying component for spraying liquid medicine, and a suction component for sucking waste liquid; the driving member is provided with an expansion component for expanding the patient's anus.

[0045] The support assembly includes a first hinged rod 6 circumferentially hinged on the outer wall of the threaded sleeve 4, and the first hinged rod 6 is hinged to an elastic support plate 7 at one end away from the threaded sleeve 4; the support plate 7 is hinged to a second hinged rod 8 at one end away from the first hinged rod 6, and the second hinged rod 8 is hinged to the outer wall of the medicine storage sleeve 3 at one end away from the support plate 7; the side walls of the first hinged rod 6 are hinged to the side walls of the second hinged rod 8 adjacent to it; the driving member is provided with a wearing assembly for facilitating the patient to wear the device conveniently.

[0046] An annular medicine storage cavity is provided inside the medicine storage sleeve 3, in which medicines for analgesia and hemostasis are stored; the spray assembly includes a piston ring 9 that slides laterally in the medicine storage cavity, and a plurality of first piston rods 10 are welded to the side of the piston ring 9 close to the threaded sleeve 4, and the ends of the first piston rods 10 away from the piston ring 9 are all welded to the threaded sleeve 4; a plurality of through holes are provided on the medicine storage sleeve 3.

[0047] The support plates 7 are all hollow inside, and are connected to a medicine delivery pipe 11; the medicine delivery pipe 11 is connected to the through hole adjacent to it, and the connection point between the two is connected to a control valve 27; the controller is used to control the operation of the control valve 27, thereby controlling the flow of the medicine liquid; a number of medicine discharge holes are opened on the side walls of the support plates 7.

[0048] A piston plate 12 is laterally slidably fitted in the waste liquid tank 5. Several second piston rods 13 are welded to the side of the piston plate 12 close to the threaded sleeve 4. The ends of the second piston rods 13 away from the piston plate 12 are welded to the threaded sleeve 4. Several suction holes are opened on the waste liquid tank 5, and the suction holes are all connected to a one-way valve 14 for supplying waste liquid into the waste liquid tank 5.

[0049] The expansion assembly includes a rotating plate 16 fixedly connected to the output shaft of the driving member by coaxial bolts. The rotating plate 16 is symmetrically hinged with an arc strip 17 on one side close to the driving member. The arc strip 17 is hinged to a limit rod 18 on the other end away from the rotating plate 16. The limit rod 18 is fixedly bonded with an elastic block 19 for expanding the patient's anus on one end away from the arc strip 17. The driving member is provided with a limiting assembly for limiting the moving direction of the elastic block 19.

[0050] The limiting assembly includes a slide rail 20 fixedly connected to the driving member with bolts; the slide rail 20 is located between the rotating plate 16 and the driving member, and the limiting rods 18 are in transverse sliding cooperation with the slide rail 20.

[0051] Medicine storage boxes 21 are symmetrically welded to the side walls of the slide rails 20, and the medicine storage boxes 21 also store medicines for analgesia and hemostasis; medicine pushing plates 22 are fitted in the medicine storage boxes 21 for transverse sliding movement; medicine pushing plates 22 are hingedly connected to medicine pushing rods 23 on the side close to the driving member, and the ends of the medicine pushing rods 23 away from the medicine pushing plates 22 are hinged to the limit rods 18 adjacent to them; the medicine storage boxes 21 are connected to the elastic blocks 19 adjacent to them, and the elastic blocks 19 are also provided with a number of medicine holes.

[0052] The wearing component includes a belt 24, both ends of which are fixedly bonded with mutually attractive magnetic blocks 25, and the bottom of the belt 24 is fixedly bonded with a connecting strip 26, and the bottom of the connecting strip 26 is fixedly bonded to the side of the driving member away from the slide rail 20.

[0053] In this embodiment, the driving element is a motor 1.

[0054] The specific implementation process is as follows:

[0055] like Figure 6 As shown, before postoperative treatment, the patient first wears the belt 24 around the waist and fixes the belt 24 with the magnetic block 25, so that the patient can wear the entire device conveniently, thereby improving the comfort and convenience of treatment.

[0056] by Figure 2For example, in the initial state, the support plates 7 are close to each other and the overall size of the device is the smallest. At this time, the medical staff inserts the threaded rod 2 and the support plates 7 into the patient's anus and intestines.

[0057] by Figure 2 For example, after the insertion is completed, the motor 1 is started through the controller, and the motor 1 drives the threaded rod 2 to rotate, so that the threaded sleeve 4 slides to the left along the threaded rod 2, and then drives the first hinged rod 6 and the second hinged rod 8 to rotate in the direction away from the threaded sleeve 4. At this time, the first hinged rod 6 and the second hinged rod 8 will drive the support plate 7 away from the threaded sleeve 4, thereby expanding in the patient's anus and intestine. Through such a design, the support plate 7 can adapt to anorses of different diameters and support them.

[0058] When the support plate 7 fits against the inner wall of the patient's anorectal cavity, the motor 1 is stopped so that the support plate 7 continues to support the patient's anorectal cavity, while avoiding excessive expansion that may cause discomfort to the patient's anorectal cavity and prevent damage to the patient's anorectal cavity.

[0059] by Figure 2 and Figure 4 For example, when the threaded sleeve 4 slides to the left along the threaded rod 2 driven by the threaded rod 2, the threaded sleeve 4 will synchronously drive the first piston rod 10 to move to the left, thereby pushing the piston ring 9 to slide to the left in the medicine storage chamber, and then discharge the medicine from the through hole. At this time, the control valve 27 is opened by the controller, and the medicine will flow from the through hole through the medicine delivery tube 11 to each support plate 7. Since the support plate 7 is in direct contact with the inner wall of the patient's anus and rectum, the medicine can be accurately sprayed onto the inner wall of the anus and rectum through the medicine discharge holes on the side wall of the support plate 7, thereby improving the utilization rate of the medicine.

[0060] by Figure 2 and Figure 5 For example, at the same time, the threaded sleeve 4 will also synchronously drive the second piston rod 13 to move to the left, thereby driving the piston plate 12 to slide to the left in the waste liquid tank 5, thereby sucking the pus and excess liquid medicine in the patient's anus and intestines into the waste liquid tank 5, thereby improving the efficiency and timeliness of waste liquid suction. During this process, the one-way valve 14 only allows waste liquid to flow from the patient's anus and intestines into the waste liquid tank 5, preventing waste liquid from flowing back from the waste liquid tank 5 to the patient's anus and intestines. This effectively avoids the risk of infection that may be caused by the backflow of waste liquid, ensures the cleanliness and hygiene of the patient's anus and intestines, and helps the patient's postoperative wound healing.

[0061] by Figure 1 and Figure 3For example, after the threaded rod 2 and the support plate 7 are inserted into the patient's anus and rectum, the elastic block 19 will contact the patient's anus; when the motor 1 drives the rotating plate 16 to rotate, the arc bar 17 will push the limit rod 18 to move along the slide rail 20 away from the motor 1, thereby driving the elastic blocks 19 away from each other, driving the skin and muscles around the patient's anus away from each other, and expanding the patient's anus. At the same time, the support plate 7 will synchronously expand the inner wall of the patient's anus and rectum, so that the patient's anus and the inner wall of the anus and rectum expand synchronously. This synchronous expansion method can simulate the natural physiological expansion process of the human body, improve the coordination of the patient's muscles and the comfort of treatment.

[0062] If the patient's anorectal dilation is performed while the perianal area remains tightly closed, the anorectal lining will be subjected to significant tension, which can easily lead to complications such as strains. The simultaneous dilation design of this embodiment effectively avoids this situation. By simultaneously dilating the perianal area and the anorectal lining, pressure is evenly distributed, reducing the risk of complications caused by uneven pressure and ensuring safe treatment for the patient.

[0063] When the limiting rod 18 slides to the sides within the slide rail 20, the limiting rod 18 simultaneously drives the medicine pushing rod 23 to move, thereby pushing the medicine pushing plate 22 to slide horizontally into the medicine storage box 21, spraying the liquid medicine in the medicine storage box 21 to the patient's anal area through the medicine discharge holes on the elastic block 19. Because the elastic block 19 fits closely to the patient's anal area, the liquid medicine can be sprayed accurately on the skin surface, relieving pain and stopping bleeding in the patient's anal area.

[0064] This embodiment, through the design of the first hinged rod 6 and the second hinged rod 8, can conveniently adjust the position of the support plate 7, so that the device maintains a minimum size when inserted into the patient's anus and rectum, facilitating insertion, reducing discomfort during postoperative treatment, and avoiding secondary damage to the patient; at the same time, after insertion, the support plate 7 can be made to fit the patient's anus and rectum, supporting the patient's anus and rectum, facilitating subsequent postoperative treatment of the patient's anus and rectum. Through this dynamic adjustment design, the device can be adapted to patients of different body shapes, improving the comprehensiveness and comfort of postoperative care.

[0065] Example 2:

[0066] As attached Figure 1 and Figure 2 As shown, different from the above embodiment, the support plates 7 are all arranged at an angle.

[0067] The specific implementation process is as follows: when the support plate 7 is inserted into the patient's anus and intestine, the inclined support plate 7 can gradually expand the patient's anus and intestine, thereby more smoothly inserting the support plate into the patient's anus and intestine, reducing the patient's discomfort.

[0068] Example 3:

[0069] As attached Figure 1 and Figure 2 As shown, the difference from the above embodiment is that the waste liquid tank 5 is detachably engaged with an elastic arc-shaped head 15 at one end away from the threaded rod 2.

[0070] The specific implementation process is as follows: When the threaded rod 2 is inserted into the patient's anus and rectum, the curved head 15 has a better guiding effect than the flat end of the threaded rod 2, allowing the threaded rod 2 and the support plate 7 to be inserted into the patient's anus and rectum more easily. After the threaded rod 2 is removed, the medical staff can remove the curved head 15 to empty the waste liquid in the waste liquid tank 5, which also facilitates cleaning of the waste liquid tank 5.

[0071] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
