Definitions
- Device for locoregional anesthesia and method for manufacturing the cannula of the device
- the invention relates to a locoregional anesthesia device and a cannula for this device.
- Locoregional anesthesia consists of anesthetizing a limb or a defined part of the body.
- the technique that has become traditional consists in introducing an electrically stimulable puncture needle as close as possible to the bundle of nerves concerned. This identification is made possible, when one is very close to the nerves concerned, by stimulation by means of a weak light electric current which is enough to trigger the muscular response. At this time, an anesthetic block is injected through the needle * and the needle is withdrawn.
- a known technique for introducing this catheter consists in using a stimulation needle on which is temporarily fixed a cannula which leaves the distal beveled end of the needle free.
- An object of the invention is to facilitate the placement and elimination of the cannula and to avoid the risks of displacement of the reinjection catheter during the elimination of the cannula.
- a device for locoregional anesthesia comprising a needle, a cannula and a catheter, the cannula consisting of a short tube provided with a fixed base suitable for being mounted on the base of the needle and the catheter being able to be threaded into the cannula, the device being characterized in that the cannula has from end to end a longitudinal slot making it possible to separate the cannula from the catheter laterally by this slot.
- the fully slotted cannula is a new medical accessory for the placement of a catheter.
- a method for manufacturing this cannula consists in manufacturing a slotted base with a wide slot, flaring one end of an unsplit tube on a conical mandrel, applying and gluing this flared end into the slot in the base (for example at using UV-curable adhesive), and splitting the tube in line with the slot in the base.
- the base and the tube of the cannula are manufactured with different synthetic resins so that the base is relatively rigid and the tube relatively flexible.
- the slot in the base is wide enough to allow the catheter to pass through the slot while the slit of the tube may have a narrower width than that of the catheter, but the lips of the slit may deviate to an extent sufficient for the catheter to force through the slit.
- the device of the invention also has one or more of the following characteristics:
- the tube has a proximal end (8) flared and glued into the slot in the base of the cannula; - the base of the cannula and the base of the needle are provided with means (10-13) cooperating for locking the base of the cannula on the base of the needle and unlocking by relative rotation of the two bases; - Said cooperating locking means are lateral teeth (10, 11) on the rear of the base of the cannula and retaining tabs (12, 13) at the front of the base of the needle;
- the catheter of the device is provided with a fixed base.
- FIG. 1 is a longitudinal diagram of the cannula with its base
- FIG. 2 is a longitudinal diagram of a neurostimulation needle
- - Figure 3 is a diagram of the cannula mounted on the needle;
- - Figure 4 is an enlarged view of the base of the cannula locked on the base of the needle;
- FIG. 5 is a view of the base of the cannula on the base of the needle after unlocking rotation
- FIG. 6 is a view of the base of the needle during the extraction of the needle.
- FIGS. 7 to 12 are successive views during manipulation for the establishment of a catheter by means of a base cannula 1 according to the invention.
- the cannula of the invention (fig.l) consists of a tube (1) and a base (2) integral with the tube and it is intended to be mounted on a needle (3) (fig.2) in so that the base (2) is locked (and unlockable on demand) on the base (4) of the needle, while the bevelled tip (5) of the needle remains visible ( Figure 3).
- the base (2) of the cannula has a wide longitudinal slot (6) and the tube (1) of the cannula has a narrow slot (7) in alignment with the slot of the base.
- the proximal end (8) flared of the tube and fixed in the end of the slot (6) of the base (2), so that the inner face of the tube is perfectly contiguous with the face internal of the base so that the transition between the base and the tube is not likely to cause a displacement of the catheter during the elimination of the cannula.
- the base (2) of the tube has two teeth (10, 11) at the rear and the base (4) of the needle present at the front two L-shaped legs (12, 13) capable of retaining the two teeth (fig. 3), while a rotation of the base of the tube allows them to be released.
- the base of the needle is designed, in a manner known per se, to allow the electrical connection of the needle to a current source by means of a conductor (14).
- the mechanical attachment system of the cannula creates a solidarity with the needle which allows to push by holding the unit very close to the puncture point, which is better in case of significant efforts.
- a 90 "rotation allows you to unlock the cannula from the needle.
- the device is extracted from a sterile pouch which includes the needle, the cannula and the catheter;
- the skin is punctured by means of the needle on which the cannula is mounted (fig. ⁇ ); - the assembly is kept (needle + cannula) close to the puncture point and the nerve is sought and identified by electrical stimulation;
- the catheter inserted can be equipped with a metal mandrel for electrical stimulation.
- a long catheter (15) provided with a fixed proximal base (16) or a central base with a flexible extension provided with a proximal base is used.
- the invention is not limited to the embodiment which has been described.
