The soft catheter is provided with a control valve. Super smooth guide wire.

Description

A new type of cyst puncture needle

1. Technical field:

The utility model relates to a medical device, in particular to a novel cyst puncture needle which can automatically suction liver and kidney cyst fluid with negative pressure, and can also place a tube for drainage.

2. Background technology:

Hepatic and renal cysts are a common disease in clinical practice. Some patients cannot be operated on due to physical reasons, so they can only be treated conservatively. They are punctured under the guidance of B-ultrasound and then anhydrous alcohol sclerosing treatment. At present, the traditional method is still used clinically: puncture needle-hose-syringe, and two people are required to cooperate to carry out the operation. One person uses a 50 ml syringe to suck the cyst fluid several times, and the assistant fixes the puncture needle with one hand, and the other hand uses Repeated clamping of the rubber tube by the hemostat greatly increases the doctor's workload and operational risks. At the same time, it is not possible to place a catheter for drainage of large cysts, which increases the recurrence rate of the cysts.

3. Contents of the utility model:

In order to solve the shortcomings of the above-mentioned background technology, the utility model provides a new type of cyst puncture needle, which is easy to operate and can automatically suck cyst fluid under negative pressure, effectively reducing the workload and operation risks of doctors. At the same time, it can also Catheter drainage can reduce the recurrence rate of cysts.

In order to achieve the above object, the technical solution adopted by the utility model is:

A new type of cyst puncture needle, including a puncture needle body, characterized in that: the puncture needle body is a double-channel puncture needle, the first channel is connected to a negative pressure device through a soft catheter, and the second channel leads to the end of the puncture needle body.

A control valve is arranged on the flexible conduit.

A super-smooth guide wire is arranged in the channel two.

Compared with the prior art, the utility model has the following advantages and effects:

The utility model is easy to use and convenient for surgical operation, can automatically suck cyst fluid under negative pressure, effectively reduces the workload and operation risks of doctors, and can also place drainage tubes to reduce the recurrence rate of cysts.

4. Description of drawings:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a schematic diagram of the structure of the super-smooth guide wire.

In the figure, 1-puncture needle body, 2-channel two, 3-soft catheter, 4-control valve, 5-negative pressure device, 6-super-smooth guide wire, 7-channel one.

5. Specific implementation methods:

Referring to Fig. 1 and Fig. 2, the utility model includes a puncture needle body 1 provided with a metering scale, a passage one 7 is connected with a negative pressure device 5 through a flexible conduit 3, and a control valve 4 is provided on the flexible conduit 3. After puncturing into the cyst under the guidance of B-ultrasound, open the control valve 4, the cyst fluid will automatically enter the negative pressure device 5, close the control valve 4 after the cyst fluid is completely washed, and inject anhydrous ethanol sclerotherapy through another channel 2 2, after 20 minutes Open control valve 4. If the cyst is large, place the ultra-smooth guide wire 6 to the cyst cavity through channel 2, pull out the puncture needle body 1, expand the skin with a dilator and place a drainage tube along the ultra-smooth guide wire 6.

The puncture needle of the utility model has double channels, one channel is connected with a negative pressure device through a flexible catheter, and can automatically suck cyst fluid under negative pressure, effectively reducing the doctor's workload and operating risks, and the other channel can be placed with a super-smooth guide wire , After dilating with a dilator, a drainage tube can be placed along the ultra-smooth guide wire to reduce the recurrence rate of the cyst.
