Detailed Description
Example 1
The embodiment provides an intra-alimentary canal retention object removing device, which comprises negative pressure suction equipment 1 as shown in figures 1-4, wherein a suction opening of the negative pressure suction equipment 1 is connected with a negative pressure suction inner tube 2, and a negative pressure switch valve or a side hole 3 is arranged on the negative pressure suction inner tube 2. For switching on or off the negative pressure of the negative pressure suction inner tube 2. The negative pressure suction inner tube 2 is sleeved with a movable sleeve 5. The inner diameter of the negative pressure suction inner tube 2 is 7-13 mm, and the preferred embodiments are 9mm, 9.9mm and 12.8mm (examination gastroscope: 9mm; treatment gastroscope: 9.9mm; enteroscope: 12.8 mm); the inner diameter of the sleeve 5 is 11-15mm, and in this embodiment is preferably 11mm, 12mm or 15mm.
When the retention matter in the alimentary canal is removed, the outer wall of the negative pressure suction inner tube 2 is provided with a scale for marking the position of the sleeve 5. The length from the end of the negative pressure suction apparatus 1 to the 0 scale is equal to the length of the sleeve 5. If the length exceeds the scale, the positive scale (cm) is adopted, and if the length is insufficient, the negative scale (cm) is adopted. The scale is used for clinical application and guides the insertion depth distance of the negative pressure suction inner tube 2 during operation.
The sleeve 5 is sleeved outside the endoscope, and is inserted into a region with serious retention of retention substances in the alimentary canal of a patient along with the endoscope, the endoscope is withdrawn, the negative pressure suction inner tube 2 is used for extending into the alimentary canal of the patient along the inner cavity of the sleeve, after the scale of the negative pressure suction inner tube reaches the scale of 0, the negative pressure suction inner tube 2 is operated to make the sleeve 5 move relatively, retention substances (blood clots, food retention or fecal waste blocks and the like) in the alimentary canal are sheared by the relative movement of the negative pressure suction inner tube 2 and the sleeve 5, and then the sheared fragments are sucked away by the negative pressure suction inner tube 2.
The end of the sleeve 5 remote from the negative pressure suction device 1 is provided with a number of side wall openings 501. In the process of the relative movement of the negative pressure suction inner tube 2 and the sleeve 5, the retention in the alimentary canal can be sheared and crushed more easily under the action of the side wall opening 501, and the chopped solid retention fragments can also freely pass through the side wall opening 501, so that the retention fragments are sucked away by the negative pressure suction inner tube 2 more easily.
The end parts of the negative pressure suction inner tube 2 and the sleeve 5, which are far away from one end of the negative pressure suction device 1, are smooth blunt ends, and the inner tube wall and the outer tube wall are both smooth treated to reduce the surface friction coefficient to the maximum extent, so that the negative pressure suction inner tube is easy to lubricate. Can effectively prevent the end parts of the negative pressure suction inner tube 2 and the sleeve 5 from damaging the mucous membrane of the inner wall of the alimentary canal of the patient.
As a preferable mode, in order to further realize the adjustment of the angles of the end portions of the negative pressure suction inner tube 2 and the sleeve 5, the device of the present embodiment is further provided with the following structure:
the sleeve 5 is provided with a knob structure 4 near one end of the negative pressure suction device 1, a plurality of small holes 503 are arranged on the sleeve 5, and the small holes 503 are arranged at one end of the sleeve 5 far away from the negative pressure suction device 1. The small holes 503 are arranged along the length direction of the sleeve 5, and a fixing device 502 is arranged at one end of the sleeve 5 away from the negative pressure suction device 1. The device further comprises a tensioning wire 504, one end of the tensioning wire 504 is coiled on the knob structure 4, and the other end of the tensioning wire is fixedly arranged on the fixing device 502; the central portion of the tensioning wire 504 passes through all the small holes 503 in sequence, and the number of small holes 503 should be large and dense enough to achieve a maximum 90 ° bend of the end of the sleeve 5. The tension wire 504 may be a steel wire.
When it is desired to adjust the angle of the end of the sleeve 5, the tightening wire 504 is retracted or released by rotating the knob structure 4, and the sleeve 5 is bent or stretched at the position where the small hole 503 is provided by the tightening wire 504. The sleeve 5 is provided with a mark for identifying the setting direction of the small hole (503). The direction of the mark (the axial extension along the arrangement direction of the small holes 503) marks the bending direction of the front end of the indication sleeve 5, so that the physician can conveniently rotate the outer body to control the bending direction of the head end.
Therefore, the bending angle of one end of the sleeve 5 (and the negative pressure suction inner tube 2 inside the sleeve 5) far away from the negative pressure suction equipment 1 is adjusted (0-90 degrees), and the negative pressure suction inner tube 2 and the end of the sleeve 5 can extend into more dead angle areas in the alimentary canal through the adjustment of the bending angle of the sleeve 5, so that the retention object removing effect is better.
According to the embodiment, the device can realize a rapid, efficient and safe function of clearing the digestive tract retention substances, can be used for emergency endoscopy, greatly improves the success rate of hemostasis under the endoscope, can also be used for patients with poor digestive tract preparation, can perform secondary intestinal tract preparation to a certain extent, avoids the influence on the detection rate of lesions such as polyps and adenomas due to unqualified intestinal tract preparation of the patients, and realizes the medical burden of the patients and the saving of public sanitary resources. Therefore, the invention has good application prospect.
