Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a novel multifunctional ovarian cyst puncture device. Background Technology

[0002] With the widespread application of laparoscopic minimally invasive surgery in gynecology, the demand for ovarian cystectomy is increasing. For ovarian cysts larger than 5 cm in diameter, traditional procedures require aspiration to reduce their size to avoid cyst rupture or damage to surrounding tissues. However, existing laparoscopic aspiration devices face the following technical limitations:

[0003] 1. High risk of cyst fluid leakage: When the puncture needle penetrates the cyst wall, the cyst fluid is prone to leak along the puncture path, which may cause abdominal infection or tumor cell dissemination.

[0004] 2. Insufficient sealing: The gap between the puncture needle and the abdominal wall puncture hole cannot be effectively sealed, causing air to mix in during negative pressure aspiration, which affects the aspiration efficiency.

[0005] Third, inconvenient operation: Traditional puncture needles need to be connected to negative pressure equipment separately, and frequent adjustments are required during the operation, which increases the complexity of the operation. Utility Model Content

[0006] In view of this, the present invention aims to provide a novel multifunctional ovarian cyst puncture device to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0007] The technical solution of this utility model embodiment is implemented as follows:

[0008] A novel multifunctional ovarian cyst aspiration device includes a puncture needle body and an aspiration system installed proximal to the puncture needle body, and also includes:

[0009] A sealing assembly is used to prevent leakage of sac fluid during puncture;

[0010] Aspiration enhancement component to improve the efficiency of capsule fluid absorption;

[0011] in:

[0012] The sealing assembly includes an elastic silicone sealing ring surrounding the middle of the puncture needle body and an annular airbag located outside the elastic silicone sealing ring. The elastic silicone sealing ring fits tightly against the puncture needle body, and the annular airbag is connected to an external inflation device through an inflation tube.

[0013] The aspiration enhancement component includes a side hole formed in the distal wall of the puncture needle body and a one-way valve disposed in the aspiration system. The side holes are evenly distributed in the circumferential direction of the puncture needle body, and the one-way valve is used to prevent the cyst fluid from flowing back.

[0014] Preferably, the puncture needle body is a hollow cylinder with an outer diameter of 3mm. The puncture needle body is adapted to the laparoscopic trocar port, and its distal end is provided with a sharp beveled tip with a bevel angle of 30°-45° to facilitate penetration of the ovarian cyst wall.

[0015] Preferably, the inner diameter of the elastic silicone sealing ring is 0.1-0.2 mm larger than the outer diameter of the puncture needle body. The outer diameter of the elastic silicone sealing ring is 10 mm and the thickness is 5 mm, which plays a role in initially sealing the puncture site. The annular airbag has an elliptical cross section, which can further enhance the sealing effect after inflation.

[0016] Preferably, the side holes are evenly arranged around the puncture needle body and have a diameter of 1 mm. The side holes are connected to the internal channels of the puncture needle body to facilitate aspiration of cyst fluid from different directions.

[0017] Preferably, the aspiration system includes a negative pressure suction tube connected to the proximal end of the puncture needle body, a one-way valve installed in the negative pressure suction tube to ensure unidirectional flow of the cyst fluid, a suction tube connected to the bottom of the negative pressure suction tube, a negative pressure pump connected in series on the suction tube, and a storage tank connected to the bottom of the suction tube.

[0018] Preferably, the negative pressure suction tube is a hollow tube and is curved, with a diameter of 2 mm and a length of 50 mm, used to draw out the cyst fluid.

[0019] Preferably, the air injection tube is a thin tube with a diameter of 0.5 mm and a length of 20 mm. One end of the air injection tube is connected to the annular airbag, and the other end of the air injection tube extends to the outside of the device for inflating the annular airbag.

[0020] Preferably, the puncture needle body, sealing component, aspiration system, and aspiration enhancement component are integrated into a single unit through integral molding or close connection, rather than being simply assembled from multiple independent parts.

[0021] Preferably, the negative pressure suction tube is also provided with a gripper block.

[0022] The present invention has the following advantages due to the adoption of the above technical solution:

[0023] 1. Double sealing to prevent leakage: The elastic silicone sealing ring and the inflatable airbag are combined to form a double barrier of "pre-tightening + dynamic sealing", which effectively prevents the leakage of cyst fluid. After the airbag is inflated, it can adapt to the surface of the cyst and avoid the failure of the seal due to the movement of the instrument.

[0024] II. Integrated Negative Pressure Aspiration: The puncture needle and negative pressure suction tube are designed as a single unit, reducing the number of steps required to connect accessories during the operation, shortening the operation time, and the one-way valve prevents backflow of cyst fluid, ensuring a stable and controllable aspiration process.

[0025] 3. Simple structure and low cost: The main components are manufactured through a one-piece molding process, which reduces assembly errors and manufacturing costs. The overall outer diameter is only 3mm, which is compatible with existing laparoscopic trocar holes and requires no additional equipment investment.

[0026] The above overview is for illustrative purposes only and is not intended to be limiting in any way.

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] like Figures 1-4 The present invention provides a novel multifunctional ovarian cyst puncture device, including a puncture needle body 1 and an aspiration system 2 installed proximal to the puncture needle body 1, and further including: a sealing component 3 for preventing leakage of cyst fluid during puncture; and an aspiration enhancement component 4 for improving the absorption efficiency of cyst fluid; wherein: the sealing component 3 includes an elastic silicone sealing ring 5 surrounding the middle of the puncture needle body 1 and an annular airbag 6 located outside the elastic silicone sealing ring 5, the elastic silicone sealing ring 5 being tightly fitted to the puncture needle body 1, and the annular airbag 6... The air tube 7 is connected to an external inflation device; the aspiration enhancement component 4 includes a side hole 8 opened on the distal wall of the puncture needle body 1 and a one-way valve 9 set in the aspiration system 2. The side holes 8 are evenly distributed in the circumferential direction of the puncture needle body 1. The one-way valve 9 is used to prevent the cyst fluid from flowing back. The puncture needle body 1 is a hollow cylinder with an outer diameter of 3 mm. The puncture needle body 1 is adapted to the laparoscopic trocar port. Its distal end is provided with a sharp beveled tip 10. The beveled tip 10 has a bevel angle of 30°-45° to facilitate penetration of the ovarian cyst wall.

[0038] like Figures 1-4As shown, the inner diameter of the elastic silicone sealing ring 5 is 0.1-0.2 mm larger than the outer diameter of the puncture needle body 1. The outer diameter of the elastic silicone sealing ring 5 is 10 mm and the thickness is 5 mm, which plays a role in initially sealing the puncture site. The annular airbag 6 has an elliptical cross section, which can further enhance the sealing effect after inflation. The side holes 8 are evenly opened around the puncture needle body 1 and have a diameter of 1 mm. The side holes 8 are connected to the internal channel of the puncture needle body 1, which helps to aspirate the bladder fluid from different directions. The aspiration system 2 includes a negative pressure suction tube 11 connected to the proximal end of the puncture needle body 1. A one-way valve 9 is installed in the negative pressure suction tube 11 to ensure unidirectional flow of the bladder fluid. The bottom of the negative pressure suction tube 11 is connected to the suction tube 12. A negative pressure pump 13 is connected in series on the suction tube 12. The bottom of the suction tube 12 is connected to the storage tank 14.

[0039] like Figures 1-4 As shown, the negative pressure suction tube 11 is a hollow tube and is curved. The negative pressure suction tube 11 has a diameter of 2 mm and a length of 50 mm and is used to draw out the bladder fluid. The air injection tube 7 is a thin tube with a diameter of 0.5 mm and a length of 20 mm. One end of the air injection tube 7 is connected to the annular airbag 6, and the other end of the air injection tube 7 extends to the outside of the device to inflate the annular airbag. The puncture needle body 1, sealing component 3, suction system 2 and suction enhancement component 4 are combined into a whole by integral molding or tight connection rather than simple assembly of multiple independent parts. The negative pressure suction tube 11 is also provided with a gripper block 15.

[0040] In this embodiment, the present invention operates as follows: First, the entire puncture device is inserted into the abdominal cavity through the laparoscopic trocar port. The doctor observes the location of the cyst and adjusts the direction of the puncture needle using laparoscopic imaging. After confirming the puncture angle, the control button at the gripper block 15 is pressed to start the aspiration system 2. At this time, the one-way valve 9 opens, and negative pressure is transmitted to the distal side hole 8 through the hollow channel of the puncture needle body 1. The puncture needle body 1 is pushed, and the sharp beveled tip 10 penetrates the ovarian cyst wall. When the side hole 8 is completely inside the cyst cavity, air is injected into the annular balloon 6 through the air injection tube 7, making it closely fit the cyst surface and the abdominal wall puncture hole, forming a double sealing barrier. Under continuous negative pressure aspiration, the cyst fluid passes through the side hole 8, through the negative pressure suction tube 11 to the suction tube 12, and finally into the reservoir 14. The doctor can monitor the puncture depth in real time through the scale markings 9 on the outer wall of the puncture needle body 1 to ensure operational safety. When the cyst has shrunk to a size suitable for dissection, release the control button to stop the negative pressure, deflate the balloon through the inflation tube 7, and slowly withdraw the puncture device. During withdrawal, the friction generated by the elastic silicone sealing ring 5 against the cyst wall prevents backflow of cyst fluid, while the deflated annular balloon 6 shrinks in volume, reducing traction damage to normal tissue. Postoperatively, the detachable negative pressure suction tube 11 is cleaned and disinfected separately. The remaining components, due to their integrated design, have no complex gaps, making cleaning and maintenance convenient. The entire procedure achieves simultaneous puncture, sealing, and aspiration, significantly improving the efficiency and safety of laparoscopic ovarian cyst surgery.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
