Description

Technical Field

[0001] The utility model relates to a rectal balloon therapeutic device, belonging to the technical field of medical equipment. Background Art

[0002] In the process of examining and treating cancer in the rectum, prostate and adjacent parts, medical imaging is needed. However, there is a problem. The rectum, anus, prostate and other parts are all soft tissue structures. In their natural state, they are collapsed and attached to each other, which will cause imaging and interference to related examinations and treatments. Therefore, during examinations and treatments, the related tissues need to be stretched and expanded to achieve the effect of separation.

[0003] At present, there are balloon structures designed for the above situation on the market, which use water injection to expand the balloon, thereby achieving the effect of expansion and separation of related tissues. However, the defect of this type of balloon is that the balloon will bulge on the surface of the central axis when relaxed, and its main axis is relatively soft and straight, which cannot fit the physiological structure of the human body well, making the operation more difficult; secondly, for patients who need radiotherapy, multiple radiotherapy sessions are required, and the specific position of the balloon cannot be accurately controlled, which will affect the treatment effect.

[0004] At present, the prior art only includes a closure device for rectal surgery as shown in CN215900687U, a rectal anastomosis support device as shown in CN215018239U, and a disposable silicone balloon catheter as shown in CN204951909U.

[0027] Example 1

[0028] The utility model provides a rectal balloon therapeutic device, comprising:

[0029] The outer catheter 1 comprises a rear outer tube 12 and a front outer tube 11 which is connected to the rear outer tube 12 and is not coaxial. The front end of the front outer tube 11 is an exhaust port, and the side wall of the front outer tube 11 is also provided with an air vent 6. The outer catheter 1 can also be a central axis structure in a medical balloon device. The axis of the front outer tube 11 and the axis of the rear outer tube 12 have an angle greater than 90 degrees. The connection between the front outer tube 11 and the rear outer tube 12 has a rounded transition structure. The diameter of the front outer tube 11 is smaller than the diameter of the rear outer tube 12. The front end of the front outer tube 11 has a smooth tube head structure to avoid stabbing the patient. The rear outer tube 12 is provided with a positioning clamp and a ruler for locating and recording the insertion length of the front outer tube 11.

[0030] The inner conduit 2 is inserted into the outer conduit 1 and extends from the rear end of the rear outer conduit 12 to the front end of the outer conduit 11. The front end of the inner conduit 2 is connected to the vent 6. The inner conduit 2 is provided with a flow stop clip 21. Figure 4 As shown, the rear end of the inner catheter 2 can be connected to a syringe 8;

[0031] The balloon 3 is sleeved on the side wall surface of the front outer tube 11 and covers the vent; the balloon 3 is bonded to the side wall surface of the front outer tube 11 on both sides of the vent 6, and the bonding length is about 2 to 10 mm; the balloon 3 is an elastic balloon and when there is no pressure in the balloon 3, the balloon 3 is closely attached to the side wall surface of the front outer tube 11 to prevent excessive protrusions, avoid causing discomfort to the patient and positioning deviation;

[0032] The working principle of this embodiment:

[0033] When there is no pressure in the balloon 3, the balloon 3 is closely attached to the side wall of the front end outer tube 11 without any protrusion.

[0034] First, the operator holds the rear outer tube 12 and inserts the front outer tube 11 into the patient's rectum. The operator injects pressure from the inner catheter 2 into the balloon 3 through the syringe 8. After the balloon 3 is expanded, it squeezes the rectal wall for positioning to ensure that it reaches the designated operation position, thereby reducing the radiation of chemotherapy rays to surrounding organs.

[0035] Secondly, after positioning, fix the current position and depth by the positioning clamp 5, read the value on the ruler and record it so that the operation can be performed on the same patient next time;

[0036] At the same time, the exhaust port 7 can release the pressure in the patient's body to increase the patient's comfort;

[0037] Finally, the rectum, prostate and adjacent structures can be squeezed by the balloon 3 to collect medical images, perform radiotherapy and other treatment operations.

[0038] Example 2

[0039] On the basis of other structures of Example 1 remaining unchanged, a capillary tube 4 is provided to be inserted into the inner catheter 2, the front end of the capillary tube 4 is connected to the inner space of the balloon 3, and the rear end of the capillary tube is connected to the pressure sensor 9; at this time, the syringe can be connected to the rear end of the inner catheter through the three-way tube 10, specifically:

[0040] like Figure 5 As shown, the rear end of the flow stop clamp 21 is configured with a three-way pipe 10, the rear end of the inner catheter 2 is connected to the first port of the three-way pipe, the pressure sensor 9 is connected to the second port of the three-way pipe 10, and the syringe 8 is connected to the third port of the three-way pipe 10; the capillary 4 extends from the rear end of the inner catheter 2 to the second port of the three-way pipe 10 and is connected to the pressure sensor 9.

[0041] The working principle of this embodiment:

[0042] When there is no pressure in the balloon 3, the balloon 3 is closely attached to the side wall of the front end outer tube 11 without any protrusion.

[0043] First, the operator holds the rear outer tube 12, inserts the front outer tube 11 into the patient's rectum, and injects pressure from the inner catheter 2 into the balloon 3 through the syringe 8. After the balloon 3 is expanded, it squeezes the rectal wall for positioning to ensure that it reaches the designated operation position, thereby reducing the radiation of chemotherapy rays to surrounding organs. During the process, the pressure inside the balloon 3 can be monitored in real time through the pressure sensor 9 and the capillary tube 4.

[0044] Secondly, after positioning, fix the current position and depth by the positioning clamp 5, read the value on the ruler and record it so that the operation can be performed on the same patient next time;

[0045] At the same time, the exhaust port 7 can release the pressure in the patient's body to increase the patient's comfort;

[0046] Finally, the rectum, prostate and adjacent structures can be squeezed by the balloon 3 to collect medical images, perform radiotherapy and other treatment operations.
