Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a multifunctional uterine cavity operation tube. Background Art

[0002] With the development of assisted reproductive technology, new technologies and methods emerge in an endless stream. At present, intrauterine perfusion, intrauterine antibiotic flushing, intrauterine stem cell therapy and endometrial biopsy are widely used in clinical practice. These treatment methods all require the use of intrauterine perfusion devices. However, balloon catheters and artificial insemination tubes are currently used instead. The balloon catheter needs to insert a balloon into the uterine cavity and expand the balloon to expand the uterine cavity. The patient will experience obvious pain due to the expansion of the uterine cavity, causing pain to the patient. However, most of the existing artificial insemination and intrauterine perfusion tubes only inject the drug solution into the uterine cavity, and cannot prevent the drug solution from flowing out of the uterine cavity tube. The drug solution stays in the uterine cavity for a short time and cannot fully play its role.

[0003] At the same time, most of the current intrauterine perfusion catheters are of the direct current type. After the drug solution is injected, it enters the uterine cavity in a straight line. Under the push of the syringe, the water flow rate is relatively high, directly impacting the bottom of the uterine cavity, which can easily cause damage to the endometrium at the bottom of the uterine cavity. At the same time, the endometrium of other parts of the uterine cavity cannot fully contact the drug solution, reducing the treatment effect.

[0004] Moreover, most of the intrauterine catheters currently used have a single function and are only suitable for intrauterine perfusion and intrauterine flushing. They cannot perform endometrial biopsy at the same time and require the use of an intrauterine sampling tube for sampling. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a multifunctional uterine cavity operation tube, and the specific technical solution is as follows:

[0006] A multifunctional uterine cavity operation tube comprises an inner tube, a nozzle and a syringe joint. The nozzle is connected to one end of the inner tube by hot melting, and the syringe joint is connected to the other end of the inner tube by hot melting. The nozzle is provided with a plurality of water outlet holes, and a piston which can slide along the inner tube is installed outside the inner tube.

[0007] Furthermore, a reflective coating is provided on the outer wall of the nozzle.

[0008] Furthermore, it also includes an outer tube with one end closed, a material collection hole is provided on the side wall of the outer tube, and the outer tube can be sleeved outside the inner tube.

[0009] Furthermore, the piston is a wedge-shaped piston made of silicone.

[0010] Furthermore, scale lines are provided on the outer wall of the inner tube.

[0011] The beneficial effects of the utility model are:

[0012] A variety of uterine cavity operations can be performed. When the uterine cavity is perfused and flushed with medicine, the syringe is inserted into the syringe connector. The liquid is pushed by the syringe and sprayed out from the water outlet of the nozzle. The medicine can contact the endometrium in multiple directions to improve the effect of the medicine. At the same time, the piston is used to block the external opening of the cervix to prevent the medicine from immediately flowing out along the cervix, thereby increasing the time the medicine stays in the uterine cavity and increasing the effect of the medicine. When taking the endometrium, the outer tube is put over the inner tube from the nozzle end and enters the uterine cavity. One hand holds the outer tube steady while the other hand pulls out the inner tube to take endometrial biopsy samples. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0020] The utility model provides a specific implementation scheme of a multifunctional uterine cavity operation tube:

[0021] like Figure 1-3 As shown, the utility model provides a multifunctional uterine cavity operation tube, including an inner tube 2 for entering the uterine cavity, a nozzle 1 for spraying liquid and a syringe connector 4 for connecting with a syringe, the nozzle 1 is connected to one end of the inner tube 2 by hot melting, the syringe connector 4 is connected to the other end of the inner tube 2 by hot melting, a through hole is provided in the syringe connector 4 for facilitating the insertion of the syringe, a plurality of water outlet holes are provided on the nozzle 1, and the injection liquid is sprayed out through the water outlet holes after passing through the nozzle 1, and the liquid will be scattered and sprayed out through the water outlet holes of the nozzle 1, and a piston 3 that can slide along the inner tube 2 is installed outside the inner tube 2.

[0022] Preferably, a reflective coating is provided on the outer wall of the nozzle 1, which can clearly display strong echoes on B-ultrasound, making it easier to check the penetration depth of the inner tube 2 by B-ultrasound.

[0023] Preferably, Figure 4 As shown, it also includes an outer tube 5 with one end closed, and a material collection hole 5.1 is provided on the side wall of the outer tube 5. When collecting materials, the outer tube 5 is sleeved on one end of the nozzle 1 outside the inner tube 2.

[0024] Preferably, the piston 3 is a wedge-shaped piston made of silicone, and the piston 3 can move on the outer wall of the inner tube 2. After the drug is injected into the uterine cavity, the piston 3 can be used to block the external cervical opening to prevent liquid from being discharged from the cervix.

[0025] Preferably, the outer wall of the inner tube 2 is provided with scale lines 2.1. In this embodiment, according to the human body structure, the length of the inner tube 2 is 10 cm. There are three scale lines 2.1, which are respectively located at 3 cm, 4 cm and 5 cm away from the top of the nozzle 1.

[0026] In addition, the syringe connector is also made of solid silicone and can be directly inserted with a syringe when in use.

[0027] When performing the operation of injecting and flushing the uterine cavity with medicine, the syringe is inserted into the syringe connector 4, and the liquid is pushed by the syringe and sprayed out from the water outlet of the nozzle 1. The medicine can contact the endometrium in multiple directions to improve the effect of the medicine. At the same time, the piston 3 is used to block the external opening of the cervix to prevent the medicine from immediately flowing out along the cervix, thereby increasing the time the medicine stays in the uterine cavity and increasing the effect of the medicine.

[0028] When performing the endometrial sampling operation, the piston 3 is removed, the outer tube 5 is put on the inner tube 2 from the end of the nozzle 1, and a part of the air in the inner tube 2 is reversely extracted through the syringe. After entering the uterine cavity, one hand stabilizes the outer tube 5, and the other hand pulls out the inner tube 2 to perform endometrial biopsy. When the water outlet is connected to the sampling hole 5.1, due to the negative pressure in the cavity between the inner tube 2 and the outer tube 5, the endometrium at the sampling hole 5.1 is sucked into the cavity between the inner tube 2 and the outer tube 5 to complete the membrane sampling. Compared with the solid plug type suction sampling, the negative pressure caused by the porous nozzle 1 is not large and is gentler. At the same time, the reverse suction of the syringe can be used to control the size of the negative pressure, that is, the suction force.

[0029] Various intrauterine operations can be performed, providing convenience for clinical work and better services for patients.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
