Definitions
- the present invention relates to an instrument suitable for various cryogenic treatments, both for the medical or paramedical sector, and for the cosmetic sector.
- an instrument is used for this purpose, into which a cartridge of liquefied gas, for example N 2 0, is introduced, which is placed in communication, generally by perforation of a membrane or a seal, with a micro- applicator in the form of a needle provided with a bore of very small diameter, the assembly being contained in a sheath held in the hand by the operator.
- gases than N 2 0 (laughing gas) can of course be used.
- the jet consists essentially of N 2 0, partly in the gaseous state and partly in the liquid state. Two major and almost prohibitive difficulties arise during the implementation of this technique.
- impurities can come for example from friction between parts of the body of the instrument between them or with the cartridge, when the latter is put in place.
- the present invention aims to avoid the described drawbacks of instruments according to the state of the art, in particular " to avoid clogging and allow better performance by facilitating their use.
- the invention also aims to propose a method for interrupting a gas flow, in particular in certain medical instruments.
- the present invention aims to provide various possibilities of use in the medical, paramedical or cosmetic field.
- Characteristic elements of the invention The Applicant has observed that the optimal operating conditions are based on the principle that a micro-applicator must have a bore of the order of 20 to 120 ⁇ m and that a regular and constant flow of the liquefied gas contained in the cartridge can only be obtained if the foreign particles possibly present in the flow of the micro-applicator are such that all those greater than 3 ⁇ m and preferably greater than 1 ⁇ m have been eliminated. Means are preferably used to remove particles between 1 and 100 ⁇ m and preferably between 3 and 60 ⁇ m depending on said bore.
- micro-applicator with a removable filter retaining particles greater than 1 ⁇ m and preferably greater than 1.5 ⁇ m.
- Filters of different kinds may be suitable, such as porous ceramics, cellulosic material, etc.
- the filter is replaced after 1 to 20 replacements of the gas cartridge. It may be advantageous for the replacement of a cartridge to automatically replace the filter with a new filter, thus avoiding clogging of the micro-applicator.
- the Applicant has also sought to resolve the difficulties observed resulting from "icing", that is to say the clogging of the micro-applicator with ice from atmospheric humidity. She realized that the use of materials, in particular synthetic materials such as polycarbonate or a resin of the PEEK type greatly reduces this phenomenon to an extent such as the possible phenomena of icing. do not cause clogging.
- the invention also aims to provide a single-use micro-applicator suitable for the cryogenic treatment instrument as described.
- Figure 1 shows a sectional view of the instrument according to the invention.
- Figures 2A to 2D show various positions of a valve fitted to the instrument.
- Figure 3 shows a detailed view of the head of the instrument illustrating the position of a filter.
- the cryogenic treatment instrument consists of a body 1. On this body, a micro-applicator
- a sheath 6 On the rear part of the body 1, a sheath 6 is mounted. It can receive a condensed gas cartridge 8. An O-ring 7 ensures the sealed connection between the cartridge and the body 1.
- the micro-applicator 2 comprises a bore 4 of 20 to 120 ⁇ m and preferably of 35 to 80 ⁇ m. It is connected with a longitudinal duct 10 with the interposition of a filter 14 which is preferably held in place on the removable front part, and more specifically at the rear of the micro-applicator 2.
- valve 3 perpendicular to the conduit 10.
- the valve can assume three distinct positions possible under the effect of a mechanical or electrical control. In a first position, a longitudinal channel 9 ensures communication, so that the gas flows from the flow control device to the micro-applicator 2. In a second position, the gas flow is closed. The third position allows the residual gas present in the cartridge 8 to be able to escape.
- the valve 3 is shown in the closed, semi-open, open position and in the exhaust position of the residual gases from the cartridge.
- the gas Before arriving at the micro-applicator 2, the gas must pass through a filter 14 shown in detail in FIG. 3.
- a filter 14 disposed on the micro-applicator 2 constitutes a particularly advantageous solution since the replacement of the filter 14 is easily achieved by dismantling the micro-applicator 2 possibly simultaneously with the dismantling of the sheath 6 for the replacement of the cartridge 8. In this case, it is not necessary (whatever useful) to use a condensed gas particularly purified for the cartridge 8.
- This filter can affect the shape of a pellet received in a final housing the conduit 10 housed in or on the micro-applicator and held in place by a capsule.
- This capsule is perforated and can be separated from the filter 14 or be integral with this filter. The latter solution facilitates the correct positioning of the filter 14, the replacement of the filter being accompanied in this case by the replacement of the capsule.
