Description

Technical Field

[0001] The invention relates to puncture and aspiration of tumor cyst fluid, in particular to a leakage-proof puncture and aspiration sleeve and a use method thereof. Background Art

[0002] With the development of minimally invasive technology, especially the application of laparoscopic technology in the field of surgery, more and more operations can be performed under laparoscopy. Compared with traditional open surgery, laparoscopic surgery has many advantages. Under laparoscopy, the tissue structure is magnified, the anatomical layers are clearer, the lesions can be directly observed at close range, and the trauma is small and the recovery is fast, which greatly improves the patient's quality of life. Laparoscopic surgery is suitable for the vast majority of benign tumors and some early malignant tumors. The technology is now very mature, but there are still some disadvantages. Laparoscopic surgery is more likely to cause iatrogenic rupture of tumors due to the limitations of instruments. Even benign tumors may lead to tumor recurrence, such as the more common ovarian mucinous tumors and ovarian chocolate cysts in gynecology. Malignant tumors can lead to clinical stage upgrades, tumor dissemination, and abdominal implants, affecting prognosis. Due to the limitation of the size of abdominal wound, for larger tumors, doctors usually use a puncture aspirator to first suck out the cystic fluid or part of the cystic fluid in the tumor, and then put it into a specimen bag and take it out from the puncture port. However, often during the process of aspirating and entering and exiting the tumor, the cystic fluid in the tumor will flow out from the puncture port or remain at the puncture aspirator tip or even flow into the abdominal cavity, increasing the chance of iatrogenic rupture. Summary of the invention

[0003] In view of the above technical problems, the present invention provides a leakage-proof puncture and suction sleeve which can reduce the chance of iatrogenic rupture.

[0004] The technical solution adopted by the present invention to solve the above technical problems is: a leakage-proof puncture and aspiration sleeve, comprising a hollow tube whose front end can be penetrated into the tumor with a puncture and aspiration device, the puncture and aspiration device is inserted into the inner cavity of the hollow tube, and the front end of the hollow tube is provided with a front balloon and a rear balloon, which, after being inflated, clamp and seal the puncture hole through which the puncture needle of the puncture and aspiration device penetrates into the tumor.

[0005] Preferably, the rear balloon is inflated and rests against the outer surface of the tumor, and the front balloon extends into the interior of the tumor.

[0006] Preferably, an anti-leakage airbag is provided on the hollow tube between the front balloon and the rear balloon, and the anti-leakage airbag can block the puncture port after being inflated.

[0007] Preferably, the anti-leakage airbag is in a cone shape with a small diameter at the front end and a large diameter at the rear end after being inflated, and the cone-shaped anti-leakage airbag rotates around the central tube.

[0008] Preferably, a protective air bag or protective film that can cover the abdominal surgical incision is provided at the rear end of the hollow tube, located outside the abdominal surgical incision.

[0009] Preferably, the front end of the hollow tube is wedge-shaped.

[0010] Preferably, the anti-leakage airbag, the front balloon and the rear balloon are inflated or exhausted by independent tracheas arranged on the wall of the hollow tube.

[0011] The present invention sets two front and rear balloons at the front end of the hollow tube. After being inflated, the two balloons expand continuously and press against each other, thereby clamping the tumor capsule wall around the puncture hole, achieving the purpose of sealing the puncture hole and preventing the tumor capsule fluid from leaking. In addition, the two inflated balloons can also firmly position the puncture suction sleeve on the tumor, making the puncture operation convenient.

[0012] The present invention also provides a method for using the puncture suction sleeve, which comprises the following steps:

[0013] (1) Before puncture, the anti-leakage balloon, the front balloon and the rear balloon are not inflated, and the puncture aspirator is inserted into the hollow tube;

[0014] (2) Use the puncture needle of the puncture aspirator to insert the front balloon along with the front end of the hollow tube into the tumor;

[0015] (3) Inflate the rear balloon and then the front balloon;

[0016] (4) Then inflate the anti-leakage airbag.

[0017] Preferably, after the puncture aspirator is inserted into the hollow tube, the puncture needle of the puncture aspirator extends out of the front end of the hollow tube.

[0018] Preferably, after the puncture is completed, the gas in the front balloon is discharged first, and then the gas in the rear balloon and the anti-leakage balloon is discharged respectively, and finally the hollow tube is withdrawn from the puncture port and the abdominal surgical port.

[0019] It can be seen from the above technical solutions that the method for using the anti-leakage puncture and suction sleeve of the present invention is simple to operate and practical, which brings convenience to the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a structural schematic diagram of a preferred embodiment of the present invention. DETAILED DESCRIPTION

[0021] Combine the following Figure 1 The present invention is described in detail. The exemplary embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0022] The present invention provides a leakage-proof puncture and aspiration sleeve, which includes a hollow tube 2 whose front end can be inserted into the interior of a tumor along with a puncture and aspiration device 1, and the puncture and aspiration device is inserted into the inner cavity of the hollow tube. The hollow tube adopts a transparent plastic tube to avoid affecting the surgical field; the front end is designed to be wedge-shaped, which is convenient for better wrapping the puncture needle to better enter the interior of the tumor and reduce the risk of cyst fluid extravasation at the moment of puncture; and the inner cavity of the hollow tube is slightly larger than the diameter of the puncture and aspiration device, so as to ensure that the puncture and aspiration device can move freely in the inner cavity and avoid interference with the hollow tube; the front end of the hollow tube is provided with a front balloon 3 and a rear balloon 4, which clamp and seal the puncture needle 5 of the puncture and aspiration device after being inflated to penetrate into the puncture hole of the tumor, so as to avoid the cyst fluid in the tumor from infiltrating into the abdominal cavity through the puncture hole during the puncture process, thereby reducing the chance of iatrogenic rupture.

[0023] Specifically, the rear balloon is inflated and rests against the outer surface of the tumor to facilitate adjustment of the depth of penetration of the front end of the hollow tube into the tumor, and the front balloon extends into the interior of the tumor. When the front end of the hollow tube penetrates into the tumor through the puncture port, the front balloon is not inflated, so that it can enter the tumor together with the front end of the hollow tube; and as the cystic fluid in the tumor is sucked out by the puncture aspirator, the tumor cyst wall collapses, and at this time, the inflated front balloon can, on the one hand, open up the interior of the tumor, which is very conducive to a wider range and more accurate operation of the puncture needle, and the surgical field of view is excellent; on the other hand, the rear balloon clamps the cystic wall around the puncture port to prevent cystic fluid leakage.

[0024] During the implementation process, as the front and rear balloons are continuously inflated, the front and rear balloons slowly contact and press against each other. Due to the deformation of the two balloons, the pressing force of the two balloon walls farther away from the puncture port may be greater, resulting in a smaller pressing force of the two balloon walls near the puncture port. Therefore, we designed the following scheme, that is, an anti-leakage airbag 6 is provided between the front balloon and the rear balloon on the hollow tube, and the anti-leakage airbag can block the puncture port after inflation. When the anti-leakage airbag is not inflated, a part of it penetrates into the tumor along with the front end of the hollow tube, and the other part remains outside the tumor, thereby ensuring that the anti-leakage airbag has a good anti-leakage effect after inflation. After inflation, the anti-leakage airbag is in a cone shape with a small front diameter and a large rear diameter, achieving the purpose of blocking the puncture port, and the cone-shaped anti-leakage airbag takes the central tube as the rotation center, which is not only convenient to process, but also its gradually increasing diameter can better adapt to the puncture port, achieving a better anti-leakage effect. During implementation, a portion of the front and rear balloons may be disposed on the outer wall of the anti-leakage airbag so that the front and rear balloons are adjacent to each other; or a certain space may be left between the front and rear balloons and the anti-leakage airbag may be disposed in this space.

[0025] The rear end of the hollow tube of the present invention is located outside the abdominal surgical port and is provided with a protective air bag 7, which can cover the abdominal surgical port to prevent the cystic fluid that may remain on the puncture and suction device from dripping on the outer wall of the abdomen when the puncture and suction device is withdrawn from the puncture and suction sleeve of the present invention, and ensure that the cystic fluid will not flow into the abdominal cavity from the abdominal surgical port, so as to further reduce the chance of iatrogenic rupture. The protective air bag also has the function of positioning the puncture and suction sleeve of the present invention to ensure that the puncture and suction sleeve is fixed on the abdominal surgical port. As another way, the rear end of the hollow tube is provided with a protective film that can cover the abdominal surgical port, which can also cover the abdominal surgical port and prevent the cystic fluid from dripping on the outer wall of the abdomen. The method of using a protective film is simpler. Preferably, the anti-leakage airbag, protective airbag, front balloon and rear balloon are all inflated or exhausted by an independent trachea 8 arranged on the wall of the hollow tube, which is convenient for adjusting the size of the airbag and has stronger adaptability. During the implementation process, two adjacent annular balloons, namely the front balloon and the rear balloon, are set at about 0.5 cm from the front end of the hollow tube. The two balloons are located on both sides of the puncture port, which is equivalent to clamping the puncture port. On the one hand, it can ensure that the puncture suction sleeve is firmly positioned on the tumor, and on the other hand, it is convenient to close the puncture port. An anti-leakage airbag is set between the two balloons to ensure that when the puncture suction device exits the tumor surface, the cystic fluid in the tumor can be prevented from flowing out of the puncture port along the front end of the hollow tube to avoid contaminating the surgical site.

[0026] The following is a detailed description of the method for using the anti-leakage puncture suction sleeve of the present invention:

[0027] Before puncture, the anti-leakage airbag, the front balloon and the rear balloon are not inflated. First, the puncture aspirator is inserted into the hollow tube of the present invention, and the insertion length is preferably such that only the puncture needle at the front end of the puncture aspirator is exposed; then the puncture aspirator and the puncture aspirator sleeve are inserted into the tumor together, and the penetration depth is about 1.5 cm. Then, the rear balloon is inflated through the trachea and pressed against the outer surface of the tumor, so that the penetration depth of the front end of the hollow tube can be conveniently adjusted; then, the front balloon is inflated, so that the puncture aspirator sleeve of the present invention is fixed on the tumor and the puncture port is closed; then, the anti-leakage airbag is inflated to block the puncture port and further seal the puncture port. During the operation, since the front and rear balloons compress the tumor capsule wall, when the puncture needle changes direction and moves forward and backward to aspirate, the capsule fluid in the tumor is prevented from leaking out of the puncture port. After the puncture is completed, the gas in the front balloon is discharged first, and then the gas in the rear balloon and the anti-leakage balloon is discharged respectively, and finally the hollow tube is withdrawn from the puncture port and the abdominal surgical port. During the implementation process, since the cystic fluid in the tumor has been sucked away, the tension of the tumor is reduced, and the cystic wall of the tumor collapses and is easily deformed. When withdrawing the puncture suction sleeve of the present invention, after the front and rear balloons are exhausted, the puncture suction sleeve is not withdrawn from the tumor first, but the tumor cystic wall around the puncture port is clamped or tied with a titanium clip, a clamp or a wire sleeve. At this time, the collapsed cystic wall covers the front end of the hollow tube. Due to the clamping of the titanium clip, clamp or ligation, the cystic fluid will not leak from the puncture port. Then the tumor is moved together with the puncture suction sleeve into the abdominal puncture TROCA, and then the puncture suction sleeve is quickly withdrawn from the TROCA, and finally withdrawn from the abdominal surgical port. This can greatly reduce the cystic fluid from entering the abdominal cavity or contaminating the abdominal puncture port. With the assistance of the puncture suction sleeve of the present invention, the tumor-free effect of open surgery can be achieved or even exceeded.

[0028] The above-mentioned implementation modes are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention.
