Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a vitreous sample intraoperative sampler. Background Art

[0002] The vitreous body, as a transparent gelatinous substance in the eyeball, fills the space between the lens and the retina and is essential for maintaining the shape and function of the eyeball. Vitreous surgery is a complex and delicate treatment in ophthalmology, and it is of great significance for the treatment of various diseases such as retinal detachment, vitreous hemorrhage, and intraocular foreign bodies. In fundus diseases and immune eye diseases, the collection and preservation of vitreous samples is not only an important basis for disease diagnosis, but also the basis for subsequent pathological analysis and scientific research.

[0003] At present, vitreous samples are mainly collected by direct aspiration with a syringe or specially designed sampling instruments. However, these methods have some shortcomings in practical applications. For example, although the syringe aspiration method is simple to operate, it is easy to damage eye tissue or cause sample contamination due to improper operation; and traditional sampling instruments may not meet the high requirements for sealing and convenience during surgery. After using the current syringe as a collector, there is a risk of sample contamination. Traditional sampling methods may introduce external contaminants due to carelessness during transportation, resulting in a decrease in sample quality and affecting diagnostic results; and some existing sampling instruments have cumbersome operating steps, which increases the difficulty and time cost of the operation; there is currently a lack of dedicated samplers with quantitative functions, which makes it difficult to meet the special needs of ophthalmic surgery for sampling instruments. Summary of the invention

[0004] The present invention provides a vitreous sample intraoperative sampler, which can solve the problem that a syringe used for vitreous sample collection cannot meet the high requirements for sealing and convenience during surgery.

[0005] To achieve the above-mentioned objectives, the present invention provides a vitreous sample intraoperative sampler, comprising a storage tube, wherein the axial ends of the storage tube are respectively connected with a first connecting hose and a second connecting hose, the end of the first connecting hose is installed with a first joint, and the end of the second connecting hose is installed with a second joint, and when the sample stored in the storage tube needs to be transferred, the first joint and the second joint are sealed and connected, and when the vitreous sample is collected, the first joint and the second joint can be matched with the existing vitrectomy incision device, so that the surgeon can quickly complete the connection and disassembly operations of the sampler during the tense operation, and since the first joint and the second joint are sealed and connected during transportation, it can be ensured that the vitreous sample will not be contaminated during transportation.

[0006] Preferably, the diameter of the first connecting hose is larger than that of the second connecting hose. The first connecting hose is used for collecting vitreous samples to facilitate the vitreous samples to enter the storage tube. The second connecting hose is relatively thin and can prevent the vitreous samples from entering the second connecting hose.

[0007] Preferably, the diameter of the first connecting hose is 5 mm, and the diameter of the second connecting hose is 1 mm, which is reasonable and reliable.

[0008] Preferably, the lengths of the first connecting hose and the second connecting hose are both at least 4 cm, ensuring that the first connector and the second connector can be butt-jointed to form a ring structure.

[0009] Preferably, an axial plug-in sleeve is provided on the first joint, and the second joint includes an outer sleeve and an inner column concentrically arranged inside the outer sleeve. When the first joint is docked with the second joint, the axial plug-in sleeve sealing sleeve is arranged on the outer side of the inner column. The structure is simple, can be matched with the existing vitrectomy incision device, and can ensure rapid docking and sealing.

[0010] Preferably, the outer side of the storage tube is provided with scale marks, which can record the sample collection volume in real time.

[0011] Preferably, a label area is provided on the outside of the storage tube, which can be used to record key information such as patient information, sample collection time, etc., and a QR code can also be provided.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The structure is simple and the unique integrated sealing structure can effectively prevent external air, microorganisms and other pollutants from entering the sampler. The joints at both ends are compatible with the existing vitrectomy incision device, which is convenient for the surgeon to quickly complete the connection and disassembly of the sampler during the tense operation. During transportation, the joints at both ends can be connected to form a closed ring structure. The sampler is designed with scale marks and label areas, supports intelligent information technology such as QR codes, and can record key information such as sample collection volume, patient information, sample collection time, etc. in real time, which is convenient for subsequent sample management and tracking.

It conforms to ergonomics, and the interface 1 and the interface 2 are matched to each other, which is convenient for timely sealing of the sample after the sampling is completed.

[0028] In this embodiment, if Figure 3-4 As shown, the first joint 1 is provided with an axial plug-in sleeve 11, and the second joint 5 includes an outer sleeve 51 and an inner column 52 concentrically arranged inside the outer sleeve 51. When the first joint 1 is docked with the second joint 5, the axial plug-in sleeve 11 sealing sleeve is arranged on the outer side of the inner column 52. The structure is simple, can be matched with the existing vitrectomy incision device, and can ensure rapid docking and sealing.

[0029] In this embodiment, the outer side of the storage tube 3 is provided with a scale mark, which can record the sample collection amount in real time. In addition, the outer side of the storage tube 3 is provided with a label area, which can be used to record key information such as patient information and sample collection time, and can also be provided with a QR code, which can record key information such as sample collection amount, patient information, sample collection time, etc. in real time, and is also convenient for subsequent sample management and tracking.
