[0002] Anorectal surgery is a clinical discipline that uses surgery as the main method to treat tumors, trauma and other diseases occurring in the anus and large intestine. Anorectal diseases are most common in the anorectum.

[0003] After anorectal surgery, the patient's wound needs to be analgesic and hemostatic. At this time, anorectal surgery postoperative analgesic and hemostatic device is needed.

[0004] Existing postoperative analgesic and hemostatic devices for anorectal surgery are usually directly inserted into the anorectal area to expand and compress the wound to achieve the effect of hemostasis. However, during the entire insertion process, the device will expand, squeeze and rub against the anorectal area, causing pain to the patient, and it is easy to damage the wound of the patient. It will also squeeze away the analgesic solution sprayed at the wound, reducing the efficacy of the medicine, resulting in poor practical effect of the device. In view of this, we propose a postoperative analgesic and hemostatic device for anorectal surgery. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a postoperative analgesic and hemostatic device for anorectal surgery to solve the technical problem that the current postoperative analgesic and hemostatic device for anorectal surgery has a poor practical effect.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. The hemostatic structure of the utility model is composed of a cannula and a rubber inflatable bag. The diameter of the cannula needs to be set relatively small to ensure that the cannula can be smoothly inserted into the patient's anus without causing expansion and compression to the patient's anus and rectum. When the cannula is fully inserted into the anus and rectum, the rubber inflatable bag is inflated through the inflation structure. At this time, the rubber inflatable bag bulges to expand and compress the patient's wound to achieve the purpose of hemostasis. The patient will not experience great pain in this process, and the wound will not be damaged due to excessive friction between the cannula and the anus and rectum during the insertion of the cannula into the anus and rectum, and the analgesic liquid sprayed on the wound will not be squeezed away, thereby ensuring the analgesic effect of the liquid on the wound. Therefore, the use effect of the utility model is better.

[0021] 2. The utility model has a notch around the cannula, and the rubber inflatable bag is sleeved in the notch. The diameter of the rubber inflatable bag is the same as the diameter of the cannula. When there is no air inside the rubber inflatable bag, the rubber inflatable bag will be hidden in the notch and will not affect the insertion of the cannula into the anorectum. Moreover, when the rubber inflatable bag is inflated to expand and press the patient's wound, the notch can limit the rubber inflatable bag so that it can stably expand around the wound without being stretched, thereby ensuring that the rubber inflatable bag can stably expand and press the patient's wound.

[0031] Furthermore, the medicine delivery structure 6 includes a cylinder 601 and a push rod 602. The cylinder 601 is screwed to the atomizing nozzle 4 through a threaded structure, and the cylinder 601 is located inside the cannula 2. The push rod 602 is inserted into the cylinder 601, and the medicine liquid is added to the cylinder 601. Then, by pushing the push rod 602, the medicine liquid inside the cylinder 601 is pushed into the atomizing nozzle 4; the top of the push rod 602 is a rubber push block, and the push rod 602 is located at the outer end of the outer cylinder 601 and a pressure block is provided. The push rod 602 pushes the medicine liquid inside the cylinder 601 into the atomizing nozzle 4 through the rubber push block, and the pressure block is convenient for people to press and push the push rod 602 with their fingers.

[0032] In a specific embodiment, the hemostasis structure 1 includes a cannula 2 and a rubber inflatable bag 3, the cannula 2 is provided with the rubber inflatable bag 3, the cannula 2 is provided with an inflatable structure 5 connected to the rubber inflatable bag 3, the diameter of the cannula 2 needs to be set relatively small to ensure that the cannula 2 can be smoothly inserted into the patient's anus without causing expansion and compression to the patient's anorectum. When the cannula 2 is fully inserted, the rubber inflatable bag 3 is inflated by the inflatable structure 5, and at this time, the rubber inflatable bag 3 bulges to expand and compress the patient's wound to achieve the purpose of hemostasis. During this process, the patient will not experience great pain, and during the process of inserting the cannula 2 into the anorectum, there will be no phenomenon of damage to the wound due to excessive friction between the cannula 2 and the anorectum. And the analgesic liquid sprayed on the wound will not be squeezed away, thereby ensuring the analgesic effect of the liquid on the wound; specifically, the inflatable structure 5 includes a three-way hose 501 and a pressurizing ball 502, the air outlet port of the pressurizing ball 502 is connected to the inner cavity of the rubber inflatable bladder 3, and the pressurizing ball 502 is arranged at the air inlet port of the three-way hose 501, and by squeezing the pressurizing ball 502, the gas is transported to the rubber inflatable bladder 3 through the three-way hose 501, thereby inflating the rubber inflatable bladder 3 and making it bulge; further, two groups of symmetrical limit rods 202 are arranged under the cannula 2, and the limit rods 202 have an arc, and the limit rods 202 are used to limit the cannula 2 to prevent the cannula 2 from being immersed in the anus, and the arc shape is more in line with the shape of the human anus.

[0033] In the utility model, a notch 201 is arranged on the cannula 2, and the rubber inflatable bag 3 is sleeved in the notch 201. The diameter of the rubber inflatable bag 3 is the same as the diameter of the cannula 2. When there is no air inside the rubber inflatable bag 3, the rubber inflatable bag 3 will be hidden and stored in the notch 201, and will not affect the insertion of the cannula 2 into the anorectum. Moreover, when the rubber inflatable bag 3 is inflated to expand and press the patient's wound, the notch 201 can limit the rubber inflatable bag 3, so that it can stably expand in one circle without being stretched, thereby ensuring that the rubber inflatable bag 3 can stably expand and press the patient's wound. The utility model solves the technical problem of poor practical effect of the current postoperative analgesic and hemostatic device used in clinical anorectal surgery through the cooperation of the cannula 2, the rubber inflatable bag 3 and the inflatable structure 5.

[0034] Working principle: When performing analgesia and hemostasis on the wound of a patient after anorectal surgery, first, add the liquid medicine into the cylinder 601, insert the push rod 602 into the cylinder 601, and then insert the cannula 2 into the anorectal area of ​​the patient. In this process, the push rod 602 is pushed to push the liquid medicine inside the cylinder 601 into the atomizing nozzle 4. The spray holes around the atomizing nozzle 4 evenly spray the liquid medicine onto the wound of the patient, ensuring the uniformity of the spraying and achieving the analgesic effect.

[0035] Secondly, when the cannula 2 is fully inserted into the anorectum, it should be noted that the diameter of the cannula 2 needs to be set relatively small to ensure that the cannula 2 can be smoothly inserted into the patient's anus and will not expand and compress the patient's anorectum. When the cannula 2 is fully inserted into the anorectum, the pressure ball 502 is squeezed to transport the gas to the rubber inflatable bag 3 through the three-way hose 501, thereby inflating the rubber inflatable bag 3. At this time, the rubber inflatable bag 3 swells to expand and compress the patient's wound to achieve the purpose of hemostasis. During this process, the patient will not experience greater pain, and the cannula 2 will not cause damage to the wound due to excessive friction with the anorectal during the insertion of the cannula 2 into the anorectal, and the analgesic solution sprayed on the wound will not be squeezed away, thereby ensuring the analgesic effect of the solution on the wound.

[0036] Finally, when there is no air inside the rubber inflatable bag 3, the rubber inflatable bag 3 automatically shrinks and resets, and is hidden in the recess 201, which will not affect the insertion of the cannula 2 into the anorectal area. Moreover, when the rubber inflatable bag 3 is inflated to expand and compress the patient's wound, the recess 201 can limit the rubber inflatable bag 3, so that it can stably expand in one circle without being stretched, thereby ensuring that the rubber inflatable bag 3 can stably expand and compress the patient's wound.
