Description

Balloon Uterine Stent

technical field

The utility model relates to a medical instrument, in particular to a balloon uterine support for avoiding adhesion after a uterine cavity operation.

Background technique

Clinically, there are more and more surgeries for the treatment of uterine lesions, such as hysteroscopic surgery, etc. The surgical operation or secondary infection of the uterine cavity will cause endometrial damage, causing the pathological symptoms of mutual adhesion of the uterine cavity wall. Adhesions cause great distress to patients and lead to related complications. At present, postoperative placement of urinary catheter or balloon uterine stent is usually used clinically to prevent intrauterine adhesions, but because the balloon of the catheter does not adapt to the shape of the cervix, the indwelling effect is limited; the balloons currently on the market The uterine stent only serves as an isolation function, and cannot observe the bleeding or hemostasis after placement. The effect of placement and the time of removal of the stent are all based on the personal judgment of the doctor.

Contents of the invention

In view of this, a balloon uterine stent is provided, which can not only effectively prevent intrauterine adhesion, but also conveniently observe postoperative bleeding.

A balloon uterine stent, comprising a catheter, an input flow channel and an output flow channel are formed in the catheter, a perforation is formed at the distal end of the catheter to communicate with the output flow channel, a balloon is sheathed on the catheter, the The balloon is in communication with the input flow channel, and the proximal end of the catheter forms an outlet to communicate with the output flow channel, and a check valve is connected to the outlet, and the check valve is in communication with the input flow channel, for feeding the ball Fluid is injected into the capsule to inflate the balloon to prevent intrauterine adhesions.

Further, the catheter is a double-lumen catheter or a multi-lumen catheter.

Compared with the prior art, when the balloon uterine stent of the utility model is used, its distal end is inserted into the uterine cavity, and the uterine cavity communicates with the output channel through the perforation on the distal end. When there is bleeding in the uterine cavity, etc. , the bleeding will flow into the discharge port through the perforation, so by observing the liquid in the discharge port, the hemostasis of the endometrial cavity can be judged conveniently and intuitively, and the indwelling time can be determined.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the balloon uterine stent of the present invention is used to prevent intrauterine adhesions after uterine cavity surgery. Inverse valve 30.

The outer diameter of the double-lumen catheter 10 is about 3mm, and a parallel input flow channel 11 and an output flow channel 13 are formed inside. The input flow channel 11 and the output flow channel 13 are completely separated for the input and output of liquid respectively. In this embodiment, the cross section of the input flow channel 11 is much smaller than the cross section of the output flow channel 13 . It can be understood that the double-lumen catheter 10 can also be other types of multi-lumen catheters, such as triple-lumen catheters.

The distal end of the double-lumen catheter 10 forms a tip 15, which is convenient for insertion into the human body. Near the tip 15, a through-hole 17 is formed on the wall of the double-lumen catheter 10. The output flow channel 13 of the dual-lumen catheter 10 is connected to the output flow channel 13 for sucking the liquid in the human body. A discharge port 19 is formed at the proximal end of the double-lumen catheter 10 , and the discharge port 19 communicates with the output channel 13 in the double-lumen catheter 10 .

The check valve 30 is connected to the side wall of the discharge port 19, and communicates with the input channel 11 in the double-lumen catheter 10, and is used to inject liquid, such as physiological saline, into the input flow of the double-lumen catheter 10. In the channel 11, it can prevent the injected liquid from flowing back. The balloon 20 is sleeved on the double-lumen catheter 10 and is close to the tip 15 of the double-lumen catheter 10, the volume may be 6ml, 12ml, etc., and the balloon 20 communicates with the input channel 11 in the double-lumen catheter 10, Therefore, liquid can be injected into the balloon 20 through the check valve 30 .

As shown in Figure 2, when the balloon uterine stent of the present invention is used clinically, first roll the balloon 20 to the smallest possible diameter, and grasp the top of the rolled balloon 20 with toothless pliers, and place the balloon 20 The forceps head is inserted into the uterine cavity above the internal os of the cervix through the cervical canal; then liquids such as normal saline can be injected into the balloon 20 through the check valve 30 until the maximum filling volume marked on the product label, so that the balloon 20 bulges Stretch the uterine cavity on the outside of the balloon 20 to avoid intrauterine adhesions; then gently pull back the toothless forceps to keep the bulging balloon 20 in place, and stick the proximal end of the double-lumen catheter 10 on the patient's Immobilization of the inner thigh completes the placement of the balloon uterine stent.

When the balloon uterine stent of the present invention is used, the distal end of the double-lumen catheter 10 is inserted into the uterine cavity, and the uterine cavity communicates with the output channel 13 through the perforation 17 on the distal end of the double-lumen catheter 10. The liquid enters the output flow channel 13 through the perforation 17 and flows outward along the output flow channel 13, and is finally discharged through the discharge port 19. When bleeding occurs in the uterine cavity, the bleeding will flow into the discharge port 19 through the perforation 17, so By observing the condition of the discharged liquid, the hemostasis of the endometrial cavity can be judged conveniently and intuitively, and the indwelling time can be determined. The longest indwelling time should not exceed 24 hours. When the discharge port 19 does not ooze out for a long time, such as more than 3 hours, it indicates that the balloon uterine stent has been placed successfully, and the saline in the balloon 20 is discharged through the check valve 30 or the catheter is cut, and the balloon uterine stent is taken out.

It should be noted that the utility model is not limited to the above-mentioned embodiments, and those skilled in the art can make other changes according to the inventive spirit of the utility model, and these changes made according to the inventive spirit of the utility model should all be Included within the scope of protection required by the utility model.
