Description

Technical Field

[0001] The present invention belongs to the technical field of medical appliances, and in particular relates to an anorectal postoperative analgesic and hemostatic device. Background Art

[0002] The anorectal department specializes in the treatment of constipation, anal fissures, anal fistulas, anal abscesses, anal stenosis, anal papillary hypertrophy, perianal eczema, mixed hemorrhoids, internal hemorrhoids, and external hemorrhoids. After intestinal surgery, analgesic hemostasis devices are often used to relieve pain and stop bleeding.

[0003] In order to prevent the patient's feces from coming into contact with the wound during defecation and causing wound infection, the existing analgesic and hemostatic devices are usually designed to be tubular, through which feces are discharged and the tube prevents feces from coming into contact with the wound, such as the patent with publication number CN113712623A.

[0004] However, this solution has the following technical problems when used: First, in the early stages of recovery, tissue fluid and blood are prone to seeping out of the wound suture site. If medicine is supplied to the affected area at this time, the medicine will easily mix with the exudate, increasing the risk of infection in the affected area; at the same time, the exudate will dilute or wash away the medicine, thereby affecting the absorption of the medicine and reducing the efficacy of the medicine.

[0005] Since the tubular analgesic and hemostatic device needs to be inserted into the affected area, the tube will hinder the excretion of feces, resulting in difficulty in defecation, which in turn causes increased abdominal pressure in the patient, natural expansion of the anal wall, and traction on the wound, affecting the recovery of the affected area. Summary of the Invention

[0006] The purpose of the present invention is to provide an anorectal postoperative analgesia and hemostasis device to solve the technical problems in the prior art.

[0007] The purpose of the present invention can be achieved through the following technical solutions: a post-operative analgesia and hemostasis device for anorectal surgery, which includes a base plate, an outer tube is installed on the base plate, an inner tube is installed on the inner side of the outer tube, a drug delivery component is installed in the outer tube, a peristaltic component is installed in the inner tube, and a transmission component is installed at the bottom of the base plate; the peristaltic component includes an elastic inner membrane, an elastic inner membrane is installed on the inner wall of the inner tube, an air extraction sleeve is installed in the inner tube for transverse sliding, the air extraction sleeve opening faces the elastic inner membrane, a transmission sleeve is installed at the bottom of the air extraction sleeve, the transmission assembly includes a transmission box, a second motor is installed in the transmission box, the output end of the second motor is connected to a gear, the gear is meshed with the transmission sleeve, and the transmission assembly includes a transmission box. A negative pressure pump is installed in the transmission box, and the negative pressure pump is connected to the vacuum sleeve; the medication assembly includes a liquid suction chamber and a liquid supply chamber, a swivel is rotatably installed at the bottom of the outer tube, a connecting rod is installed on the swivel, and a double-headed slide is installed on the connecting rod, and the two sides of the double-headed slide extend into the liquid suction chamber and the liquid supply chamber respectively, one end of the double-headed slide is connected to piston one, and piston one slides in the liquid suction chamber; the other end of the double-headed slide is connected to a double push plate, the double push plate is located inside the liquid supply chamber, and piston two is slidably installed in the liquid supply chamber, and piston two is located between the double push plates; the transmission assembly includes a liquid storage box and a medicine liquid tank, and the liquid storage box and the medicine liquid tank are connected to the liquid suction chamber and the liquid supply chamber respectively.

[0008] As a further optimization or improvement of this solution, a motor 1 is installed in the transmission box, and the motor 1 drives the rotating ring to rotate.

[0009] As a further optimization or improvement of this solution, the drug delivery component also includes an air cavity, which is fixedly installed on the outer wall of the outer tube, an elastic layer is installed on the air cavity, the elastic layer fits the affected area, a pull plate is installed in the air cavity, a pull rope is installed on the pull plate, and a rotating shaft is installed between the liquid suction chamber and the liquid supply chamber; a take-up roller is installed at the output end of the motor 2, and the take-up roller passes through a transmission and a gear; the pull rope is connected to the take-up roller through a rotating shaft.

[0010] As a further optimization or improvement of this solution, a seat cushion is installed on the base plate, and the seat cushion is located on both sides of the outer tube.

[0011] As a further optimization or improvement of this solution, a guide block is installed on the top of the outer tube, and one side of the guide block is set as an inclined surface. The feces in the intestine is introduced into the inner tube through the guide block and discharged through the inner tube.

[0012] As a further optimization or improvement of this solution, the double push plates include push plate 1 and push plate 2, and piston 2 is located between push plate 1 and push plate 2; the double-headed slide plate and piston 1 are detachably connected.

[0013] As a further optimization or improvement of this solution, the double-headed slide is connected to piston one via an electromagnetic suction cup.

[0014] Beneficial effects of the present invention: (1) When medication is required for the affected area, the double-headed slide moves toward the liquid supply chamber. At this time, push plate 1 moves away from piston 2, and push plate 2 moves toward piston 2. Due to the sliding fit between the double-headed slide and piston 2, piston 2 does not move. During the movement of the double-headed slide toward the liquid supply chamber, the double-headed slide drives piston 1 to move toward the liquid supply chamber, generating negative pressure in the liquid suction chamber, sucking tissue fluid and blood exuded from the affected area into the liquid suction chamber, and promptly cleaning the exudate from the affected area, thereby reducing the risk of infection in the affected area.

[0015] Specifically, as the double-ended slide moves, push plate 2 contacts piston 2 and pushes it to move. Piston 2 pushes the liquid medicine from the liquid supply chamber through the liquid outlet, allowing the liquid medicine to act on the affected area. However, when the liquid medicine initially contacts the affected area, it mixes with residual exudate from the wound, thereby diluting the medicine and affecting its efficacy. Therefore, in the present invention, while piston 2 is used to discharge the liquid medicine from the liquid supply chamber, the double-ended slide drives piston 1 to move, drawing the mixture of the liquid medicine and residual exudate into the liquid aspiration chamber, thereby ensuring the efficacy of the medicine.

[0016] (2) The present invention connects the vacuum sleeve to a negative pressure pump. When the negative pressure pump is running, the vacuum sleeve generates negative pressure, and the vacuum sleeve sucks the elastic inner membrane into the vacuum sleeve, causing the top elastic inner membrane to be concave. The gear is driven to rotate by the second motor, and the gear engages with the rack on the transmission sleeve to drive the transmission sleeve downward. The transmission sleeve drives the vacuum sleeve to move synchronously. As the vacuum sleeve moves, the concave part of the elastic inner membrane moves from top to bottom. By simulating intestinal peristalsis, the patient's defecation is promoted, ensuring that the patient's defecation is smooth, and avoiding the patient's continued increase in abdominal pressure due to difficulty in defecation during defecation, thereby aggravating the expansion of the anal wall and causing wound traction.

[0017] (3) During the operation of the motor 2 of the present invention, the motor 2 drives the take-up roller to rotate, causing the take-up roller to reel in the pull rope, and the pull rope drives the pull plate to move into the air cavity, and the elastic layer fits the compressed wrinkles. Since the elastic layer fits the affected area, the elastic layer will gather the anal wall of the affected area, inhibit the expansion of the anal wall of the affected area, and avoid pulling the wound.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] See also Figures 1-9, a postoperative analgesic and hemostatic device for anorectal surgery, comprising a base plate 1, an outer tube 5 is mounted on the base plate 1, an inner tube 6 is mounted on the inner side of the outer tube 5, a drug delivery component 9 is mounted in the outer tube 5, a peristaltic component 8 is mounted in the inner tube 6, and a transmission component 3 is mounted at the bottom of the base plate 1; the peristaltic component 8 comprises an elastic inner membrane 802, an elastic inner membrane 802 is mounted on the inner wall of the inner tube 6, an air extraction sleeve 801 is mounted in a transverse sliding manner in the inner tube 6, the air extraction sleeve 801 opening faces the elastic inner membrane 802, a transmission sleeve 803 is mounted at the bottom of the air extraction sleeve 801, the transmission component 3 comprises a transmission box 301, a motor 2 307 is mounted in the transmission box 301, an output end of the motor 2 307 is connected to a gear 303, the gear 303 is meshed with the transmission sleeve 803, a negative pressure pump 304 is mounted in the transmission box 301, and the negative pressure pump 304 is engaged with the air extraction sleeve 801 Connection; the dosing component 9 includes a liquid suction chamber 901 and a liquid supply chamber 902, a swivel 914 is rotatably installed at the bottom of the outer tube 5, a connecting rod 913 is installed on the swivel 914, and a double-headed slide 908 is installed on the connecting rod 913, and the two sides of the double-headed slide 908 extend into the liquid suction chamber 901 and the liquid supply chamber 902 respectively, and one end of the double-headed slide 908 is connected to piston 1 910, and piston 1 910 slides in the liquid suction chamber 901; the other end of the double-headed slide 908 is connected to a double push plate 911, and the double push plate 911 is located inside the liquid supply chamber 902, and a piston 2 912 is slidably installed in the liquid supply chamber 902, and the piston 2 912 is located between the double push plates 911; the transmission component 3 includes a liquid storage tank 306 and a medicine liquid tank 305, and the liquid storage tank 306 and the medicine liquid tank 305 are respectively connected to the liquid suction chamber 901 and the liquid supply chamber 902.

[0032] Specifically, the transmission box 301 is installed with a motor 302, and the motor 302 drives the rotating ring 914 to rotate.

[0033] It should be noted that the liquid outlet on the liquid supply chamber 902 is a constant pressure outlet, and the liquid inside the liquid supply chamber 902 needs to be discharged through the piston 912 to act on the affected area.

[0034] It should be noted that when the present invention is used, the ends of the outer tube 5 and the inner tube 6 equipped with the guide block 4 are inserted into the rectum through the anus, so that the outer wall of the outer tube 5 fits the affected area.

[0035] When medication is needed to the affected area, see Figure 6First, liquid medicine is injected into the liquid supply chamber 902 through the liquid medicine tank 305. After the liquid supply chamber 902 is filled with liquid medicine, the injection into the liquid supply chamber 902 is stopped. The motor 1 302 drives the rotating ring 914 to rotate. The rotating ring 914 drives the double-headed slide 908 to rotate through the connecting rod 913, causing the double-headed slide 908 to move toward the liquid supply chamber 902. At this time, the push plate 1 9110 moves away from the piston 2 912, and the push plate 2 9111 moves closer to the piston 2 912. Due to the sliding cooperation between the double-headed slide 908 and the piston 2 912, the piston 2 912 does not move during this process. During the movement of the double-headed slide 908 toward the liquid supply chamber 902, the double-headed slide 908 drives the piston 1 910 to move toward the liquid supply chamber 902, so that the piston 1 910 extracts the gas inside the suction chamber 901, and the suction chamber 901 generates a negative pressure, sucking the tissue fluid and blood exuded from the affected area into the suction chamber 901, and cleaning the exudate from the affected area in time, reducing the risk of infection in the affected area.

[0036] As the double-headed slide 908 moves, the push plate 2 9111 contacts the piston 2 912 and pushes the piston 2 912 to move. The piston 2 912 pushes the liquid medicine in the liquid supply chamber 902 out through the liquid outlet of the liquid supply chamber 902, so that the liquid medicine acts on the affected part. However, when the liquid medicine initially contacts the affected part, the liquid medicine will mix with the exudate remaining on the wound, thereby diluting the medicine and affecting the efficacy. Therefore, in the process of the present invention discharging the liquid medicine in the liquid supply chamber 902 through the piston 2 912, the double-headed slide 908 drives the piston 1 910 to move, and the mixture of the liquid medicine and the residual exudate is sucked into the liquid suction chamber 901 to ensure the efficacy of the medicine. When the liquid medicine acting on the affected part does not contain exudate or the exudate content does not affect the efficacy, the double-headed slide 908 is disconnected from the piston 1 910, and the medicine is continuously administered to the affected part by the double-headed slide 908 pushing the piston 2 912.

[0037] After the drug administration is completed, the mixed liquid in the liquid aspiration chamber 901 is pumped into the liquid storage tank 306, and the double-headed slide 908 is reset.

[0038] When the patient is defecating, although the outer tube 5 and the inner tube 6 can isolate the affected area from the feces, the outer tube 5 and the inner tube 6 will also hinder the discharge of feces, resulting in difficulty in defecation. Figure 3The present invention connects the suction sleeve 801 to the negative pressure pump 304. When the negative pressure pump 304 is running, the suction sleeve 801 generates negative pressure, and the suction sleeve 801 draws the elastic inner membrane 802 into the suction sleeve 801, causing the top elastic inner membrane 802 to be concave. The motor 2 307 drives the gear 303 to rotate, and the gear 303 engages with the rack on the transmission sleeve 803 to drive the transmission sleeve 803 downward. The transmission sleeve 803 drives the suction sleeve 801 to move synchronously. As the suction sleeve 801 moves, the concave part of the elastic inner membrane 802 moves from top to bottom. By simulating intestinal peristalsis, the patient's defecation is promoted, ensuring smooth defecation for the patient, and preventing the patient from increasing abdominal pressure during defecation, thereby aggravating anal wall expansion and causing wound traction.

[0039] See also Figure 5-10 The drug delivery component 9 also includes an air cavity 903, which is fixedly installed on the outer wall of the outer tube 5, and an elastic layer 904 is installed on the air cavity 903, and the elastic layer 904 fits the affected part. A pull plate 905 is installed in the air cavity 903, and a pull rope 906 is installed on the pull plate 905. A rotating shaft 907 is installed between the liquid suction cavity 901 and the liquid supply cavity 902; a take-up roller 308 is installed at the output end of the motor 2 307, and the take-up roller 308 is connected to the take-up roller 308 through a transmission 309 and a gear 303; the pull rope 906 is connected to the take-up roller 308 through the rotating shaft 907.

[0040] It should be noted that when a patient defecates, abdominal pressure increases, causing the anal wall to naturally expand. In the early stages of surgery, this expansion can easily cause wound stretching, hindering recovery of the affected area. Therefore, during operation, the second motor 307 of the present invention drives the take-up roller 308 to rotate, causing the take-up roller 308 to reel in the pull cord 906. The pull cord 906 drives the pull plate 905 to move into the air cavity 903, causing the elastic layer 904 to conform to the compressed wrinkles. As the elastic layer 904 conforms to the affected area, it gathers the anal wall of the affected area, inhibiting expansion of the anal wall and preventing wound stretching.

[0041] When the wound on the affected part recovers its mobility, the pull cord 906 can be disconnected from the take-up roller 308. When the wound on the affected part is fully recovered, the device can be removed.

[0042] It should be noted that the elastic layer 904 is composed of two layers, namely natural rubber and a breathable base material. The base material is used to maintain the shape of the elastic layer 904 so that the natural rubber on the base material fits the affected anal wall.

[0043] See also Figure 1 A seat cushion 2 is installed on the substrate 1 , and the seat cushion 2 is located on both sides of the outer tube 5 .

[0044] It should be noted that straps can be installed on both sides of the base plate 1 to fix the device on the patient.

[0045] See also Figure 2-Figure 3A guide block 4 is installed on the top of the outer tube 5, and one side of the guide block 4 is set as an inclined surface. The feces inside the intestine is introduced into the inner tube 6 through the guide block 4 and discharged through the inner tube 6.

[0046] It should be noted that, when in use, the outer tube 5 and the inner tube 6 need to be inserted into the rectum through the anus with one end of the guide block 4 installed, so that the outer wall of the outer tube 5 fits the affected area. During defecation, feces in the intestine are introduced into the inner tube 6 through the guide block 4 and discharged.

[0047] See also Figure 5-Figure 9 The double push plates 911 include push plate 1 9110 and push plate 2 9111, and piston 2 912 is located between push plate 1 9110 and push plate 2 9111; the double-headed slide 908 and piston 1 910 are detachably connected.

[0048] Specifically, the double-headed slide 908 is connected to the piston 1 910 via an electromagnetic suction cup.

[0049] It should be noted that an electromagnetic suction cup is installed on the double-headed slide 908, and the piston 1 910 is connected to the electromagnetic suction cup to achieve a disconnectable connection between the double-headed slide 908 and the piston 1 910.

[0050] The implementation principle of the present invention is: insert the outer tube 5 and one end of the inner tube 6 equipped with the guide block 4 into the rectum through the anus, so that the outer wall of the outer tube 5 fits the affected area.

[0051] When medication is needed to the affected area, see Figure 6 First, liquid medicine is injected into the liquid supply chamber 902 through the liquid medicine tank 305. After the liquid supply chamber 902 is filled with liquid medicine, the injection into the liquid supply chamber 902 is stopped. The motor 1 302 drives the rotating ring 914 to rotate. The rotating ring 914 drives the double-headed slide 908 to rotate through the connecting rod 913, causing the double-headed slide 908 to move toward the liquid supply chamber 902. At this time, the push plate 1 9110 moves away from the piston 2 912, and the push plate 2 9111 moves closer to the piston 2 912. Due to the sliding cooperation between the double-headed slide 908 and the piston 2 912, the piston 2 912 does not move during this process. During the movement of the double-headed slide 908 toward the liquid supply chamber 902, the double-headed slide 908 drives the piston 1 910 to move toward the liquid supply chamber 902, so that the piston 1 910 extracts the gas inside the suction chamber 901, and the suction chamber 901 generates a negative pressure, sucking the tissue fluid and blood exuded from the affected area into the suction chamber 901, and cleaning the exudate from the affected area in time, reducing the risk of infection in the affected area.

[0052] As the double-headed slide 908 moves, the push plate 2 9111 contacts the piston 2 912 and pushes the piston 2 912 to move. The piston 2 912 pushes the liquid medicine in the liquid supply chamber 902 out through the liquid outlet of the liquid supply chamber 902, so that the liquid medicine acts on the affected part. However, when the liquid medicine initially contacts the affected part, the liquid medicine will mix with the exudate remaining on the wound, thereby diluting the medicine and affecting the efficacy. Therefore, in the process of the present invention discharging the liquid medicine in the liquid supply chamber 902 through the piston 2 912, the double-headed slide 908 drives the piston 1 910 to move, and the mixture of the liquid medicine and the residual exudate is sucked into the liquid suction chamber 901 to ensure the efficacy of the medicine. When the liquid medicine acting on the affected part does not contain exudate or the exudate content does not affect the efficacy, the double-headed slide 908 is disconnected from the piston 1 910, and the medicine is continuously administered to the affected part by the double-headed slide 908 pushing the piston 2 912.

[0053] After the drug administration is completed, the mixed liquid in the liquid aspiration chamber 901 is pumped into the liquid storage tank 306, and the double-headed slide 908 is reset.

[0054] When the patient is defecating, although the outer tube 5 and the inner tube 6 can isolate the affected area from the feces, the outer tube 5 and the inner tube 6 will also hinder the discharge of feces, resulting in difficulty in defecation. Figure 3 The present invention connects the suction sleeve 801 to the negative pressure pump 304. When the negative pressure pump 304 is running, the suction sleeve 801 generates negative pressure, and the suction sleeve 801 draws the elastic inner membrane 802 into the suction sleeve 801, causing the top elastic inner membrane 802 to be concave. The motor 2 307 drives the gear 303 to rotate, and the gear 303 engages with the rack on the transmission sleeve 803 to drive the transmission sleeve 803 downward. The transmission sleeve 803 drives the suction sleeve 801 to move synchronously. As the suction sleeve 801 moves, the concave part of the elastic inner membrane 802 moves from top to bottom. By simulating intestinal peristalsis, the patient's defecation is promoted, ensuring smooth defecation for the patient, and preventing the patient from having difficulty defecating during defecation, which leads to a continuous increase in abdominal pressure, thereby aggravating anal wall expansion and causing wound traction.

[0055] When a patient defecates, abdominal pressure increases, causing the anal wall to naturally expand. In the early stages of surgery, this expansion can easily cause wound stretching, hindering recovery of the affected area. Therefore, during operation, the second motor 307 of the present invention drives the take-up roller 308 to rotate, causing the take-up roller 308 to reel in the pull cord 906. The pull cord 906 drives the pull plate 905 to move into the air cavity 903, causing the elastic layer 904 to conform to the compressed wrinkles. As the elastic layer 904 conforms to the affected area, it gathers the anal wall of the affected area, inhibiting expansion and preventing wound stretching.

[0056] When the wound on the affected area has completely healed, remove the device.

Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application.
