Description

An auxiliary device for preventing leakage during ovarian cyst puncture. Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an auxiliary device for preventing leakage during ovarian cyst puncture. Background Technology

[0002] Ovarian tumors are classified as benign or malignant. During surgery, if a malignant ovarian tumor ruptures, it can cause intraperitoneal seeding. Some benign ovarian tumors, such as mucinous cystadenomas, can also develop into peritoneal mucinous tumors if they rupture during surgery, exhibiting malignant biological behavior and seriously threatening the patient's health. Modern laparoscopic surgery has rapidly developed, offering advantages over traditional open surgery such as less trauma, shorter recovery time, and smaller surgical scars. However, the risk of cyst rupture during laparoscopic ovarian cystectomy is significantly higher than with open surgery. Therefore, effectively aspirating cyst fluid, reducing tumor size, and preventing extravasation and intraperitoneal seeding are crucial during laparoscopic ovarian cystectomy.

[0003] The existing patent publication number CN215606142U discloses an auxiliary device for preventing leakage during ovarian cyst puncture, including a fixation component and a puncture component. The fixation component is fixed to the outer wall of the cyst, and the puncture component penetrates the fixation component fixed to the outer wall of the cyst to enter the cyst for puncture and aspiration. The fixation component includes a fixing connecting block and an adhesive silicone film extending circumferentially along the fixing connecting block. The fixing connecting block has a cap-shaped structure with a closed top and a hollow interior. The fixing connecting block and the adhesive silicone film are integrally connected. The fixed block with a closed top and a hollow interior used in this invention replaces the solid connecting block in the prior art, reducing running resistance during the movement of the puncture needle and avoiding perforation of the cyst wall. By setting up a gripping mechanism, the fixed block is gripped during use, with multiple gripping points to maintain a firm fixation.

[0004] When existing puncture needles penetrate a cyst, the cyst's capsule expands like a balloon, and the puncture hole may be larger than the needle hole's diameter, causing cyst fluid to leak out directly and contaminate the body's internal organs. Therefore, we propose an anti-leakage auxiliary device for ovarian cyst puncture to address the aforementioned problems. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the invention, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Therefore, the purpose of this invention is to provide an auxiliary device for preventing leakage during ovarian cyst puncture, which can solve the problem that when the existing puncture needle passes through the cyst, the cyst's membrane turns into a ball, and the puncture hole may be larger than the diameter of the needle hole, causing the cyst fluid to seep out directly and contaminate the body.

[0007] To solve the above technical problems, the present invention provides an auxiliary device for preventing leakage during ovarian cyst puncture, which adopts the following technical solution: it includes a puncture needle body, a support base is fixedly installed on the top of the puncture needle body, the support base includes an adjustment component, and the puncture needle body includes an anti-leakage component.

[0008] The adjustment assembly includes a screw, a connecting shell, and a lifting plate. The screw is rotatably connected to the inside of the support base, and the top end of the screw passes through the top of the support base. The lifting plate is slidably disposed inside the support base. The connecting shell is fixedly installed at the bottom of the lifting plate, and the lifting plate is threadedly connected to the surface of the screw.

[0009] The leak-proof component includes an annular sealing strip, which is fixedly installed at the bottom of the connecting shell. A groove is provided inside the puncture needle body. The annular sealing strip is adapted to the groove and is slidably disposed inside the groove. An extension port is provided on the outside of the groove, and the bottom end of the annular sealing strip can extend to the outside of the puncture needle body through the extension port.

[0010] Optionally, multiple limiting rods are fixedly installed at equal intervals between the upper and lower inner walls of the inner cavity of the support base. Each limiting rod penetrates the interior of the lifting plate, and the lifting plate is slidably disposed on the surface of the multiple limiting rods.

[0011] Optionally, a knob is fixedly installed at the top of the screw, and an anti-slip strip is fixedly provided on the surface of the knob.

[0012] Optionally, the knob, screw, and support base are all provided with internal slots.

[0013] Optionally, a one-way membrane is embedded at the bottom of the support base.

[0014] Optionally, both the one-way membrane and the annular sealing strip are made of medical-grade materials.

[0015] In summary, the present invention has at least one of the following beneficial effects:

[0016] 1. By setting up adjustment components and anti-leakage components, after the operator inserts the puncture needle body through the surface of the patient's cyst, they can turn the knob. The knob rotation drives the screw rotation, which in turn moves the surface lifting plate downward. When the lifting plate moves, it drives the annular sealing strip downward through the connecting shell. The bottom end of the annular sealing strip slides through the groove and finally extends to the outside of the puncture needle body through the extension port. The annular sealing strip can be used to seal the edge of the puncture hole and the needle, thereby preventing cyst fluid leakage and improving the safety of the operation. It is highly practical.

[0017] 2. By setting up a tubing groove, staff can extend the infusion tube through the groove to the bottom of the puncture needle, thereby reaching the inside of the cyst to perform a series of surgical procedures on the patient's cyst. By setting up a one-way membrane, fluid can be prevented from flowing out of the tubing groove, thus improving the safety of the surgery. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to Figures 1-6.

[0027] Example 1, referring to Figures 1-6, in this embodiment, to address the problem that when the puncture needle passes through a cyst, the cyst's membrane tends to bulge outwards, creating a hole larger than the needle's diameter, causing cyst fluid to leak out and contaminate the body, this invention discloses an anti-leakage auxiliary device for ovarian cyst puncture.

[0028] It includes a puncture needle body 1, a support base 2 fixedly installed on the top of the puncture needle body 1, an adjustment component inside the support base 2, and a leak-proof component inside the puncture needle body 1.

[0029] The adjustment assembly includes a screw 3, a connecting shell 4, and a lifting plate 5. The screw 3 is rotatably connected to the inside of the support base 2, and the top end of the screw 3 passes through the top of the support base 2. The lifting plate 5 is slidably disposed inside the support base 2. The connecting shell 4 is fixedly installed at the bottom of the lifting plate 5, and the lifting plate 5 is threadedly connected to the surface of the screw 3.

[0030] The leak-proof component includes an annular sealing strip 6, which is fixedly installed at the bottom of the connecting shell 4. A groove 7 is provided inside the puncture needle body 1. The annular sealing strip 6 is adapted to the groove 7 and is slidably disposed inside the groove 7. An extension port 8 is provided on the outside of the groove 7, and the bottom end of the annular sealing strip 6 can extend to the outside of the puncture needle body 1 through the extension port 8.

[0031] The outer side of the annular sealing strip 6 can fit against the outer side of the puncture needle body 1.

[0032] Multiple limiting rods 9 are fixedly installed at equal intervals between the inner walls of the upper and lower sides of the inner cavity of the support base 2. Each limiting rod 9 penetrates the interior of the lifting plate 5, and the lifting plate 5 is slidably arranged on the surface of the multiple limiting rods 9.

[0033] The limit rod 9 is used to limit the lifting and lowering of the lifting plate 5.

[0034] A knob 10 is fixedly installed at the top of the screw 3, and an anti-slip strip 11 is fixedly provided on the surface of the knob 10;

[0035] The anti-slip strip 11 makes it more stable for workers to turn the knob 10.

[0036] The knob 10, screw 3 and support base 2 are all provided with tube grooves 12 inside;

[0037] By setting up the tubing groove 12, the staff can extend the infusion tube through the tubing groove 12 to the bottom of the puncture needle body 1, thereby extending into the cyst to perform a series of surgical operations on the patient's cyst.

[0038] A one-way membrane 13 is embedded at the bottom of the support base 2;

[0039] One-way membrane 13 prevents patient bodily fluids from leaking out through tubing 12 and posing a danger to staff.

[0040] Both the one-way membrane 13 and the annular sealing strip 6 are made of medical-grade materials.

[0041] The specific working principle is as follows: First, the staff inserts the bottom of the puncture needle into the patient's cyst. Then, by rotating the knob 10, the staff rotates the screw 3, which in turn moves the surface lifting plate 5 downward. As the lifting plate 5 moves, it moves the annular sealing strip 6 downward through the connecting shell 4. The bottom of the annular sealing strip 6 slides through the groove 7 and finally extends to the outside of the puncture needle body 1 through the extension port 8. The annular sealing strip 6 can be used to seal the edge of the puncture hole and the needle, thereby preventing leakage of cyst fluid. Subsequently, when performing infusion and aspiration, the staff can extend the infusion tube through the tube groove 12 to the bottom of the puncture needle body 1, thereby extending into the cyst to perform a series of surgical operations on the patient's cyst. By setting a one-way membrane 13, the staff can prevent the fluid from flowing out of the tube groove 12.

[0042] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
