Description

The utility model relates to the field of medical technology and can be used to introduce drugs into the pathological zones determined by ultrasound scanning, mainly in the treatment of joint diseases of all degrees.

Known methods for treating coxarthrosis, by introducing a hyaluronic acid preparation into the crack of the hip joint under ultrasound control using Hitachi 8500 devices equipped with a 20 MHz biopsy sensor or a 7.5-13 MHz biopsy linear sensor with standard sterile disposable nozzles for punctures (patent for the invention of the Russian Federation No. 2396961, published on 08/20/2010), Toshiba Capasee with nozzles for biopsy, which allows you to control the path of the Cook DCHN 18-20-U needle with an echo tip (Genzhera N.A., Ozerov S.K., Men shikova I.V., Pak Yu.V., Sergienko S.A., Petukhova N.V. Experience of local intra-articular therapy with injections of the hyaluronic acid preparation ostenil in the hip joint under ultrasound control in osteoarthritis. Sonography. 2004, v.5, No. 4, p. 367-370), and a linear 7.5 MHz or 3.5 MHz biopsy Star256 sensor, Hitachi-Esaote with a sterile biopsy head [Miglior A., Tormenta S., Martin LSM, Valente C, Massafra U., Granata M. , Alimonti A. Open pilot study of ultrasound-guided intra-articular iniection of hylan GF 20 (Synvisc) in the treatment of symptomatic hip osteoarthritis. Clinical Rheumatology, 24 (3), p. 285-289]. Intra-articular injection is carried out by inserting a 9 cm spinal needle through a biopsy nozzle.

However, in all known methods, nozzles (often disposable) were used for puncture biopsy, the designs of which do not allow the syringe with a needle filled with a dose of the drug to be installed on them and the needle is fixed firmly when the drug is administered. This explains the lack of accuracy in the administration of the drug for intraarticular replacement of synovial fluid and the limited possibilities of nozzles.

Also known are puncture nozzles (biopsy adapters) for ultrasonic sensors (http://www.ooo-mit.ru/urology/nasadki.html; http://www.tiaramed.ru/U1-trazvukovye-skanery-Mindray/Mindray- DP-6600.html; http // www.rosmed.ru / scatalog / show / 9396 / Nasadka_punkcionnaya_dlya datchika sektornogo bio psiya http://www.medafarm.ru/medoborud/datchiki_dlya_datchika_sektornogo_biudiya http://www.medafarm.ru/med / datchiki-dlya-aloka-ssd-500-ssd-1100; http://www.umetex.ru/nashi-predlojeniya/biopsiinye-nasadki.html),

These puncture nozzles have the same disadvantages as described above.

Of the known puncture nozzles closest to the claimed utility model is the "Puncture nozzle for ultrasound sensor sector (biopsy)" (http://www.rosmed.ru/scatalog/show/9396/Nasadka_punkcionnaya_dlya_datchika_sektornogo_biopsiya, see the Appendix to the application materials), selected as a prototype and containing a housing, one end of which is intended for attachment to an ultrasonic sensor, and the other end of the housing is a tool holder,

Known puncture nozzle has the same disadvantages as the previous analogues.

The technical problem, which is aimed at solving the utility model, is to create the design of the nozzle for injection under ultrasonic control, which ensures the accurate introduction of drugs into pathological zones and enhances the functionality of ultrasonic sensors.

The technical problem is solved due to the fact that the injection nozzle is under ultrasonic control, containing a housing, one end of which is designed to be attached to an ultrasonic sensor, and the other end of the housing is a tool holder, equipped with a device for attaching a syringe with a needle mounted on the carriage.

The technical problem is also solved due to the fact that the device for mounting the syringe with a needle is made in the form of spaced supports with adjustable distance relative to each other, depending on the size of the used syringe.

The technical problem is also solved due to the fact that the tool holder is configured to change the angle of direction and axial movement of the syringe with the needle and has guides for moving the carriage, and the carriage has the ability to move along the guides in the holder.

In comparison with the known analogues, in the proposed design of the nozzle for injection under ultrasonic control there is a device for attaching a syringe with a needle mounted on a carriage moving along the guides in the holder, which is configured to change the angle of direction and axial movement of the syringe with the needle. Changing the angular and axial position of the syringe with the needle ensures the accuracy of the introduction of drugs into the pathological zones determined by ultrasound scanning. In addition, in the proposed design, it became possible to use various sizes of the syringe with a needle and hard fix it in the process of drug administration.

The proposed design of an injection nozzle under ultrasonic control can be used for injections not only with ultrasonic sensors for joints, but also with other ultrasonic sensors, for example, used to “remove” varicose veins by non-surgical method of echosclerotherapy, the essence of which is that using Ultrasonic monitoring The specialist carries out targeted injections and uniform distribution of sclerotherapy throughout the affected venous collector (http://varicoz-spb.ru/varix/fle bopanel / stv / dgst / .This leads to the expansion of the functionality of ultrasonic sensors.

As a result of this, we can conclude that the proposed utility model ensures the achievement of the task and is new.

The proposed nozzle for injection under ultrasonic control is presented in the drawings, where:

figure 1 - presents a block diagram of a nozzle for injection under ultrasound control ;.

Figure 2 - presents the design of the nozzle for injection under ultrasonic control in section A.

The nozzle for injection under ultrasonic control (figure 1) contains a housing 1, one end of which is made, for example, in the form of a clamp, and the other end is a holder 2, in the groove of which is placed a carriage 3, a syringe 4, supports 5 and 6. Support 5 mounted on the carriage 3 motionless. The support 6 is mounted on the carriage with the possibility of longitudinal adjustment .. Each of the supports 5 and 6 contains a clamp 7 and 7 ^1, respectively. The holder 2 is made with the possibility of rotation around axis 8 and fixation at a given angle. There is a needle at the end of the syringe 9. An ultrasound probe is indicated by the number 10.

The carriage 3 (figure 2) contains the guides 11 with the possibility of fixing in a certain position (the latches in figure 1 and 2 are not shown). Each clip 7 and 7 ¹ is provided with a spring (figure 2 shows the spring 12 related to the clip 7.).

The nozzle for injection under ultrasound control is used as follows.

First, diagnostic ultrasound examinations of the scanned object are performed, the diagnosis is verified, the degree of the disease is clarified, and the drug is prescribed. Next, install the support 6 at a distance from the support 5, corresponding to the standard size of the syringe 4, filled with the drug and the installed needle 9. Having pressed the clamps 7 and 7 ^1, set the syringe 4 with the needle 9 on the supports 5 and 6. The holder 2 is set at an angle due to the parameters of the scanned object and fix its position. According to the parameters of the injection needle 9, determine the position of the carriage 3 and fix it. Determine the injection site using an ultrasonic transducer 10, remove the carriage 3 from the lock and feed it forward along the guides 11 until the needle 9 is inserted to the required depth and re-lock the carriage 3. Inject the piston of the syringe 4. After the injection is completed, remove the carriage 3 from the fixation, take it back until the needle leaves the patient’s body and fix it in the retracted position. Press clamps 7 and 7 ¹ and remove syringe 4 with needle 9 from supports 5 and 6.
