Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and in particular to a gastrointestinal tract cleaning device during surgery. Background Art

[0002] Intestinal obstruction is one of the common gastrointestinal emergency surgeries. The cause is usually intestinal tumors or intestinal adhesions. When intestinal obstruction occurs, the obstructed intestine will be accompanied by a large amount of feces, body fluids, and gas accumulation. Long-term obstruction will cause excessive expansion and edema of the intestine and even cause intestinal rupture, which seriously threatens the patient's life safety.

[0003] In addition, literature shows that the healing effect of anastomosis in gastrointestinal surgery is also closely related to the degree of intestinal cleanliness. For example, in patients with gastric cancer and colorectal tumors, intestinal tumors occupy the digestive tract cavity, resulting in insufficient intestinal preparation before surgery, which may contaminate the surgical field when opening the digestive tract during surgery, increasing the risk of infection. At the same time, it will also increase the risk of poor anastomosis healing and anastomotic fistula. Therefore, for such patients, intraoperative gastrointestinal cleaning is very necessary and important.

[0004] At present, most of the intestinal decompression cleaning devices commonly used in clinical practice are made by manually combining a threaded tube and a garbage bag into a closed device, or using a disposable suction head to extend into the intestine to directly suck the intestinal contents. The above devices have many disadvantages during use: 1. The place where the device is connected needs to be sutured with silk thread, and the steps are very cumbersome; 2. The connection port is prone to overflowing intestinal contents and polluting the surgical area; 3. The combination of the threaded tube and the garbage bag does not have good sealing properties, and the odor is easy to spread in the operating room, and the subsequent treatment is troublesome and incomplete; 3. The threaded tube device relies on the surgeon's hand squeezing to discharge feces, which makes it difficult to achieve a good cleaning effect; 4. The device that connects the disposable suction head to the waste liquid bucket (with good air tightness, and the sucked waste liquid is collected in the waste liquid bag, and then poured into the sewage sewer for unified treatment) also has trouble connecting the interface and is easy to overflow fecal liquid to pollute the surgical area; 5. The disposable suction head cannot control the suction force, which can easily cause intestinal mucosal damage and bleeding. 6. When encountering dry stool blocking the device pipeline, the above devices cannot cope with it.

[0005] There is an urgent need for an intraoperative gastrointestinal cleaning device to solve the existing problems. Utility Model Content

[0029] The utility model is described in detail below in conjunction with the accompanying drawings.

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] Example 1

[0032] In the present embodiment, an intraoperative gastrointestinal cleaning device comprises: a suction tube 1 and a fixture 2, wherein a suction head 3 is provided at one end of the suction tube 1, and a negative pressure mechanism is provided at the other end, the suction head 3 is slidably sleeved with a fixture 2 for fixing the suction head 3 in the gastrointestinal tract, and the fixture 2 and the suction head 3 are configured to be matched with a trumpet shape; when the intestine is opened for surgery, it is necessary to clean up the obstructed remains in the intestine, and one end of the suction tube 1 is connected to the negative pressure mechanism, the negative pressure mechanism generates negative pressure, so that the suction tube 1 generates suction, and the suction head 3 is extended into the intestinal opening, the intestinal opening is slightly smaller than the trumpet-shaped suction head 3, so that the suction head 3 is not easy to fall out of the intestine due to external force after entering the intestine; after the suction head 3 enters the intestine, the fixture 2 is pushed forward, and since the suction head 3 and the fixture 2 are configured to be matched with a trumpet shape, after the fixture 2 is pushed forward, the fixture 2 and the suction head 3 press the intestine tightly, so that it remains sealed, and the entire cleaning device is not easy to fall out of the intestine, causing pollution to other areas, thereby preventing secondary damage to the patient.

[0033] Furthermore, the suction head 3 is provided with an external thread, and the fixture 2 is provided with an internal thread matching therewith; after the suction head 3 is inserted into the intestine, the fixture 2 is screwed forward through the internal and external threads matching the suction head 3, so as to achieve the purpose of connecting the intestine to the cleaning device. The advantage of such a configuration is that the amount of screwing-in of the fixture 2 can be accurately controlled through the thread, so as to prevent other operations during surgery from affecting the clamping force of the fixture 2; further, the position of the fixture 2 can also be fixed by the thread, so as to prevent the position of the fixture 2 from moving during surgery, causing pollution to other areas, and preventing secondary injury to the patient.

[0034] Furthermore, one end of the suction tube 1 includes an outer shell 4 and an inner core 5, the outer shell 4 is sleeved on the inner core 5, the suction head 3 is arranged at the end of the outer shell 4, one end of the inner core 5 is connected to the suction tube 1 providing suction, and the other end is provided with a pounding piece 6; after fixing the cleaning device as in the above steps, hold the outer shell 4 with one hand to keep the outer shell 4 motionless, and pinch the suction tube 1 at the rear end of the outer shell 4 with the other hand to twitch it back and forth slightly, so that the pounding piece 6 at the front end can crush the obstruction in the intestine, so that the suction tube 1 at the rear end can suck out the obstruction in the intestine; specifically, the end of the pounding piece 6 is set to a relatively sharp arc, which can crush the obstruction to the maximum extent without damaging the intestine; the advantage of such a setting is that when encountering dry stool or other rough gastrointestinal contents, the movable device can be used to reduce it and thus suck it out.

[0035] Furthermore, the edge of the pounding blade 6 is set to be a smooth arc shape; Figure 2 As shown, the arc shape can crush dry stool or other rough gastrointestinal contents to the greatest extent, while the smooth arc can prevent the intestines from being damaged during crushing.

[0036] Furthermore, it includes an elastic soft membrane 7, one end of which is sleeved on the outer shell 4 and the other end of which is sleeved on the suction tube 1; the soft membrane 7 is arranged at the interface between the outer shell 4 and the suction tube 1 to maintain the negative pressure state in the suction tube 1 when pumping back and forth, and at the same time can also provide a certain rebound force, so that pumping back and forth is more labor-saving.

[0037] Furthermore, the suction tube 1 is provided with an internal interface 8. The internal interface 8 can be inserted into a water pipe for cleaning or an endoscope for endoscopy during surgery. The advantage of such a configuration is that the device can clean or endoscopy the intestine without removing the cleaning device, thereby preventing various instruments from being repeatedly inserted from the intestinal opening to cause secondary harm to the patient. Such a configuration can integrate multiple functions into one, reduce the workload of medical workers, and reduce the risk of secondary trauma to patients.

[0038] Furthermore, the inner interface 8 is provided with a sealing cover 9; when the inner interface 8 is not needed, the sealing cover 9 is covered to maintain negative pressure in the suction tube 1, thereby effectively sucking out dry stool or other rough gastrointestinal contents.

[0039] Furthermore, a rubber ring 10 with a hole is provided in the inner interface 8. Figure 4 As shown, the diameter of the small hole in the perforated rubber ring 10 is smaller than the diameter of the water pipe and the endoscope, so that after the two pass through the rubber ring 10, the suction tube 1 can still remain sealed to prevent pollutants from overflowing from the inner interface 8 and polluting the surgical environment. At the same time, during flushing, negative pressure can be maintained in the suction tube 1 to ensure normal suction work.

[0040] Furthermore, the fixator 2 is provided with an extension component 11, and an extension handle is added at the rear end of the fixator 2. During surgery, since the fixator 2 is located deep and it is not convenient to reach out and twist it, an extension handle is provided to facilitate the rotation of the fixator 2 at the rear end.

[0041] Furthermore, the suction tube 1 is provided with a suction regulating switch 12; the suction regulating switch 12 can control the magnitude of the negative pressure suction, and can timely adjust the magnitude of the suction in coordination with the surgical progress, thereby improving the surgical efficiency.

[0042] Embodiment 2

[0043] Based on the first embodiment, Figure 3 As shown, the pounding piece 6 is configured to be in a wavy arc shape, which can more effectively crush dry stool or other rough gastrointestinal contents.

[0044] Embodiment 3

[0045] On the basis of the first embodiment, the outer wall of the suction head 3 and the inner wall of the fixer 2 are wrapped with a layer of silicone to prevent intestinal damage during clamping.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
