Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and specifically, to an abdominal deflation device. Background Art

[0002] ESD (Endoscopic Submucosal Dissection) is a mature endoscopic treatment method applicable to large early-stage digestive tract cancers. During endoscopy, doctors use special knives to dissect the tumor along with a part of the mucosal layer, which can more thoroughly remove the tumor and retain more normal tissues, reducing the occurrence of postoperative complications.

[0003] However, for some tumors that grow between the inside and outside of the digestive tract, to ensure complete resection of the diseased tissue and prevent the spread of tumor cells in the abdominal cavity, doctors usually perform active perforation, that is, cut the digestive tract mucosa to form a channel between the digestive tract and the abdominal cavity. In this way, doctors can more directly approach and remove tumor sites that are originally difficult to completely remove.

[0004] After active perforation, the function of the digestive tract is temporarily affected, similar to a "deflated balloon" whose folds cannot be fully expanded, which will affect the vision and operation. For this reason, doctors will use an endoscope to continuously inject gas to keep the digestive tract in an inflated state, but this will also cause the gas to spread to the abdominal cavity, causing abdominal distension in patients and increasing patient discomfort.

[0005] Currently, to relieve abdominal gas accumulation, the common practice is to perform abdominal deflation operations using a 20-ml syringe. Medical staff will draw 5 ML of sterile injection water with a syringe at the right lower abdomen, then directly insert it into the abdomen, pull out the piston, and observe whether there are bubbles generated to judge whether the deflation is successful. After confirmation, the nursing staff needs to hold the syringe by hand or use adhesive tape to paste and fix it to ensure the stability of the needle position.

[0006] However, there are some deficiencies in the existing technologies: 1. Waste of human resources: At least one caregiver is required to continuously hold the syringe by hand or monitor the firmness of the adhesive tape pasting, which is particularly inconvenient during long surgeries. 2. Easy displacement of the syringe: Even with the use of adhesive tape for fixation, due to the possible movement of the patient during the surgery or due to changes in abdominal distension, the syringe may still shift or fall off, resulting in the failure of the deflation operation or the need for repeated adjustment. 3. Inconvenient operation: During the continuous monitoring and adjustment of the syringe, the operations of medical staff may be restricted, affecting the workflow and efficiency in the operating room. 4. Infection risk: The contact area between the skin and the syringe may not be sufficiently sealed, with tiny gaps, posing a potential infection risk, and each operation requires changing the adhesive tape and disinfecting the skin, increasing the complexity of the preoperative preparation work. 5. Difficulty in observing air bubbles: In the existing technologies, observing whether air bubbles are generated mainly relies on the naked eye observation of medical staff, which may lead to misjudgment due to differences in angles, light, or individual experience. Summary of the Invention

[0007] The purpose of the present utility model is to provide an abdominal cavity deflation device to solve the problems raised in the above-mentioned background technology.

[0008] The technical solution adopted by the present utility model is as follows: An abdominal cavity deflation device includes: a hollow needle, an observation cylinder, and a base.

[0011] Furthermore, the limit mechanism is connected to the observation cylinder for fixing the adjustment rod.

[0012] Furthermore, an adjustment plate is arranged at the connection between the hollow needle and the adjustment rod.

[0013] Furthermore, the shape of the adjustment plate matches the inner cross-section of the observation cylinder.

[0014] Furthermore, a sealing ring is arranged at the edge of the adjustment plate.

[0015] Furthermore, a fixing strap is arranged at the upper end of the observation cylinder.
