Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an ovarian tumor puncture device and a method of using the same. Background Art

[0002] Ovarian cysts are cystic structures filled with fluid or solid matter that form inside the ovaries. They are common tumors of the female genitalia. If an ovarian cyst grows rapidly or ruptures due to trauma, the fluid in the cyst enters the abdominal cavity and stimulates the retroperitoneum, which can cause acute abdominal symptoms such as severe abdominal pain, nausea, and vomiting. In severe cases, bleeding, peritonitis, and shock may occur in the abdominal cavity, which is very harmful to women. For ovarian cysts, minimally invasive surgical techniques represented by laparoscopic techniques have been widely used in the surgical treatment of benign and malignant gynecological diseases. In the process of performing surgery on large cystic or cystic-solid adnexal masses (including those from the ovary or fallopian tube), if the clinical preoperative judgment is that the mass is likely to be benign, minimally invasive surgery may be preferred. However, since the mass is too large to be directly bagged and removed from the puncture hole. Clinically, it can be considered to first aspirate the cystic fluid of the mass to reduce the volume of the mass, so as to facilitate the bagging and removal of the specimen. However, since early ovarian cancer cannot be clearly diagnosed by appearance and preoperative auxiliary examinations, intraoperative freezing is often required to confirm it. Therefore, if intraoperative puncture causes cystic fluid leakage, it may cause the cancerous tissue of the malignant tumor to cause artificial intraperitoneal metastasis and dissemination through the cystic fluid leakage, which will change the patient's pathological stage and increase the risk of disease recurrence, seriously affecting the patient's prognosis.

[0003] Therefore, an ovarian tumor puncture device is needed to solve the above technical problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention designs an ovarian tumor puncture device and a method of using the same. When in use, the device cooperates with an airbag and an external sleeve. After puncture, the puncture site can be sealed by the airbag, and the sealing is performed by a combination of internal and external sealing, which can ensure the sealing performance during use to a great extent; it can effectively prevent the leakage of cystic fluid caused by puncture during surgery, which may cause the cancerous tissue of the malignant tumor to cause artificial intra-abdominal metastasis and dissemination through the leakage of cystic fluid.

[0011] Specifically in the present embodiment, in order to ensure that the clamping head 11 can be completely attached to the outer wall of the patient's ovary during use, the clamping head 11 at the front end of the internal tube 2 is a hollow truncated cone structure and is made of rubber and silicone materials; the open truncated cone structure is used to fit the ovarian wall 4, so that it will not damage the ovarian wall 4 during clamping, and the rubber material also ensures safety during use. Example 2

[0012] In this embodiment, by means of the clamping flap 32 and the fixing ring 31, when in use, the puncture needle 3 can be directly pulled back to a certain distance, and then the puncture needle 3 can be fixed by the cooperation between the clamping flap 32 and the rear end of the built-in tube 2, so that the airbag 22 at the front end can form a ring-shaped structure to ensure the sealing performance during squeezing. Specifically, the rear end of the puncture needle 3 is fixedly installed with a fixing ring 31 in a linear array, and a plurality of clamping flaps 32 are installed in a circumferential array on the fixing ring 31, and the ends of the clamping flaps 32 are extended outwardly. Two clamping flaps 32 are provided, and they are symmetrically arranged. The connection between the clamping flap 32 and the fixing ring 31 is elastic, and the clamping flap 32 is installed at the position corresponding to the arc groove 25. In the vertical direction of the inflation tube 21, arc grooves 25 are symmetrically opened on the inner wall of the built-in tube 2; the arc grooves 25 are arranged to accommodate the clamping flap 32 so that the clamping flap 32 can be limited and released; specifically, the process is that when it is necessary to pull back and fix, the puncture needle 3 is directly pulled, so that the clamping flap 32 directly and the outer sleeve 1 After the clamping flap 32 and the end surface of the outer sleeve 1 are detached, a fixing effect is formed, and at the same time, the fixing ring 31 and the clamping flap 32 can ensure the adjustability of the fixed position. Example 3

[0013] In this embodiment, based on the ovarian tumor puncture device described in Embodiment 1 and Embodiment 2, specifically, the method of using the device is as follows: S1: First, the outer tube 1, the inner tube 2 and the puncture needle 3 are taken out or assembled as required; in addition, it is necessary to ensure that the puncture needle 3 is inside and the head is not exposed, so as to ensure that other tissues will not be damaged when inserted; S2: After reaching the ovary, the puncture needle 3 is pushed out and directly penetrated into the ovary; then the airbag 22 is inflated through the inflation tube 21, and the inflation is in a non-inflated state; S3: After the inflation is completed, the outer sleeve 1 is rotated so that the clamping head 11 of the outer sleeve 1 clamps the ovarian wall 4 and fixes it; S4: Then the puncture needle 3 is returned, so that the clamping flap 32 pops out, and forms a fixed effect with the internal tube 2 to complete the sealing puncture.

[0014] In the above process, in order to ensure that the outer sleeve 1, the inner tube 2 and the puncture needle 3 do not interfere with each other or can be operated smoothly when rotating or pulling, the length of the outer sleeve 1 should be smaller than the puncture needle 3 and the inner tube 2, but the length can meet the needs under laparoscope.
