Problems solved by technology

Since the prostate is adjacent to the rectum, the rectum is in constant peristalsis, which will cause slight shaking of the prostate, which will cause damage to normal cells during radiotherapy
At the same time, hyperthermia radiotherapy will also cause damage to rectal cells

Embodiment 1

[0030] Embodiment one: if figure 1 As shown, the thickness of the middle end 32 of the balloon is greater than the thickness of the front end 33 and the rear end 31 of the balloon. When filling, the thinner ends of the balloon are easier to fill, so that the balloon has an ellipsoidal structure, and the middle end of the balloon supports the prostate. Because the middle end is thicker, it can have a large elastic recovery force and can Hold the prostate firmly, and at the same time, due to the gravity of the prostate, the middle end will be pressed down to form a concave structure, and the thicker middle end can also provide material support for the re-deformation of the balloon.

Embodiment 2

[0031] Embodiment two: if figure 2 As shown, the inner side of the middle end 32 of the balloon is provided with a reinforcing rib 34 , and the reinforcing rib 34 is arranged around the inner surface of the balloon 3 . When the balloon is filled, the reinforcing rib pulls the middle end of the balloon so that the middle end is less likely to be deformed than the front and rear ends, so that the balloon presents an ellipsoidal structure. When the balloon supports the prostate, the inner Ribs provide support for the balloon. The reinforcing rib is arranged inside the middle end of the balloon, so that the reinforcing rib does not protrude from the surface of the balloon, and the balloon will not affect the deformation of the balloon when supporting the prostate, thereby not affecting the concave structure of the balloon.

[0032] The control valve can adopt the existing gas nozzle structure, and can also adopt the following structure. Such as image 3As shown, the control va...

Abstract

The invention discloses a prostate and rectum isolating device, and relates to the technical field of medical instruments. The device comprises a hose, the head end of the hose is closed, the tail end of the hose is open, a hollow first channel is formed in the hose, and the first channel communicates with the tail end and the head end of the hose; the head end of the hose is provided with a balloon, the balloon is arranged at the head end of the hose in a wrapping mode, the hose is further provided with a first through hole, the first through hole is communicated with the hose and the balloon, the balloon is of an ellipsoidal structure after being filled, and the balloon is made of soft materials; a control valve is arranged at the tail end of the hose, and the control valve enables the interior of the hose to be communicated with the outside or to be closed. When the prostate of a patient is treated, the prostate is isolated from the rectum, so that shaking of the prostate is avoided, the prostate is accurately positioned, and meanwhile, damage to the rectum caused by treatment is prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a prostate and rectum isolation device. Background technique [0002] When the prostate is diseased, it is often necessary to use radiotherapy to irradiate the tumor tissue with radiation such as X-rays, Y-rays, and electron beams, and use the biological effects of radiation to kill the tumor tissue in the largest amount, so as to achieve the effect of treating the prostate. During the radiotherapy process, the prostate needs to be accurately positioned and fixed, so that only the lesion is treated with radiotherapy and the damage to normal cells is reduced. Since the prostate is adjacent to the rectum, the rectum is in constant peristalsis, which will cause slight shaking of the prostate, which will cause damage to normal cells during radiotherapy. At the same time, high-temperature radiotherapy will also cause damage to rectal cells. [0003] For women's cervical lesi...
