Technical Field

The invention relates to the technical field of medical instruments, in particular to a double-cavity ovum taking needle with an information transmission device.

Background

At present, the proportion of patients with hypofunction of ovarian reserve and advanced age is gradually increased, the number of dominant follicles on both sides of the patients is gradually increased, a double-cavity ovum-taking needle is used for taking ovum, and if necessary, culture solution is used for washing the follicular cavity for multiple times and repeatedly pumping for 6-10 times; if the number of dominant follicles exceeds 3, a single-cavity ovum-taking needle can be used, if the number of the ova taken out is less than that of the ova taken out under ultrasound in the ovum taking process, a double-cavity ovum-taking needle can be used, and each follicle is washed by culture solution for 6-10 times so as to obtain more ova.

The single-cavity ovum taking needle is not provided with a structure with the diameter of 0.3mm, but the double-cavity ovum taking needle is provided with the structure, and the ovum flushing and the ovum sucking are simultaneously carried out at the ovum taking moment, which is the unique flushing cavity structure of the double-cavity ovum taking needle, but the quality of the obtained ovum from the double-cavity ovum is poorer than that from the single-cavity ovum taking according to the current clinical data, besides the abnormal function of the ovary of a patient, the tuning angle of the needle tube and the negative pressure of the tube opening possibly have certain influence on the quality of the obtained ovum in the repeated flushing process. However, at present, a double-cavity ovum taking needle or a related accessory device which can test the negative pressure and the vortex angle of the orifice of the tube is clinically lacked, so some technical indexes of the ovum taking operation cannot be quantitatively evaluated with the clinical ovum quality and other consequences.

The Chinese patent application: CN2759407Y discloses a single-cavity ovum fetching device, which belongs to medical apparatus and instruments, the structure of which comprises a puncture needle, a handle, a collecting pipe, a sealing plug, a negative pressure connecting seat and a negative pressure connecting pipe, wherein the end part of the puncture needle is provided with an ultrasonic echo zone, one end of the collecting pipe is connected with the puncture needle through the handle, the other end of the collecting pipe passes through the sealing plug, a through hole is arranged on the sealing plug, one end of the negative pressure connecting pipe is connected with the through hole on the sealing plug, and.

The Chinese patent application: CN202010190U discloses a double-cavity ovum fetching device. The structure of the device comprises a puncture needle, a handle, an oocyte collecting pipe, a sealing plug, a negative pressure connecting seat and a negative pressure connecting pipe, and is characterized in that the puncture needle is a double-cavity puncture needle, one cavity is an ovum taking channel, and the other cavity is a flushing channel; a main channel and an auxiliary channel penetrate through the handle; the ovum taking channel of the puncture needle is communicated with the oocyte collecting tube through the handle main channel; the flushing channel of the puncture needle is communicated with one end of the flushing collecting pipe through the handle auxiliary channel, and the other end of the flushing collecting pipe is provided with a flushing pipe connecting seat.

Although the two devices can realize basic egg taking operation, the two devices cannot realize measurement of the vortex angle of the needle tube and the negative pressure value of the tube opening, so that the two indexes cannot be evaluated to be related to clinical indexes such as double-cavity egg taking efficiency, egg quality and the like, and the two devices are not suitable for being used in the auxiliary procreation egg taking operation through vaginal puncture.

Therefore, in view of the above, there is a need for a novel ovum retrieval needle capable of acquiring the negative pressure at the port of the ovum retrieval needle tube and the swirling angle value of the washing liquid flow so as to count the correlation between the negative pressure and the swirling angle value of the washing liquid flow and the clinical indexes of ovum retrieval efficiency and ovum quality in the ovum retrieval operation, improve the quality of the assisted reproduction ovum retrieval operation, and retain the functions of the original double-cavity ovum retrieval needle, and no report is found about the novel double-cavity ovum retrieval needle with the information transmission device.
