Abstract

The invention relates to a device for injecting into or tapping joint cavities with a hollow canula (11) which can be inserted into the joint cavity and is connected to an injection or tapping syringe (9). In order to prevent damage to the cartilage or bone bounding the joint cavity, the invention proposes that the syringe (9) be fitted so as to be movable in the insertion direction in a supporting device (1) which can be supported on the surface (4) of the patient's body in the region of the insertion point and has, in the region of the supporting surface, an ultrasonic measuring head (3) of a sonar measuring device (6) which generates a control signal corresponding to the permissible depth of insertion which in turn controls a system for limiting the depth of insertion allocated to the supporting device (1).

Description

The invention relates to a device for injection in or for puncturing joint cavities, with an in the hollow cannula insertable with the is connected to an injection or puncture syringe, which is slidable in the insertion direction Support device is mounted, which in the area of Puncture site on the patient's body surface is supported and in the area of the support surface Ultrasonic measuring head of a sonar measuring device points.

When applying medication in orthopedics It is often required for medical or surgical practice Lich, the drug directly in joint cavities to inject. Likewise, it is often necessary to get yourself accumulating body fluid through puncture from joint cavities to remove. In both cases, one with a syringe (piston pump) or another suitable pump connected hollow cannula through the Ge Steering gap inserted into the joint cavity. It is because of the diversity in anatomy of the patient often difficult to pinpoint the joint cavity to meet and in particular to avoid that the Spit  the injection needle or puncture cannula penetration too deep which limits the joint cavity injured the cartilage or bone. To such iatrogenic Avoiding damage is when injecting medication elements in joint cavities or when puncturing Liquids from joint cavities the skill of the Physician particularly required.

When using a state of the art (DE 25 53 404 A1) known device of the introduction the treating doctor has the advantage that Use the hollow cannula to penetrate the joint cavity to monitor the sonar measurement and when needed to be able to correct the case accordingly. But also with Use of this known device is Risk that the hollow cannula is inserted too deep, so that the bones defining the joint cavity or Cartilage will be injured.

The same danger exists with one according to the state technology (US 37 21 227) also known sonar Measuring device, the ultrasonic measuring head with a Passage channel for the passage of the hollow cannula egg ner injection or puncture syringe is provided and the distance between the syringe of the cannula and the limbs areas inside the patient's body shows.

It is an object of the invention, the device of a gangs mentioned in such a way that a accidentally inserting the hollow cannula too deeply the joint cavity is prevented.  

To achieve this object, the invention proposes hend from the device of the type mentioned before that the sonar measuring device is one of the allowed Corresponding penetration depth generates control signal, wel ches a device associated with the support device controls to limit the penetration depth.

It is the first time with the device according to the invention possible, the insertion depth of the hollow cannula automatically limit such that the opening of the hollow cannula in the joint cavity opens out and a sufficient Ab stood by the cartilages bounding the joint cavity or bone is observed. This will violate through the adjacent cartilage or bone Reliably avoid deep insertion of the hollow cannula and prevents the hollow cannula from sticking to the bone bends.

An advantageous development of the invention provides that the sonar measuring device is also an optimal one Puncture localizing signal generated. Here the sonar measuring device is also used to Joint required for the insertion of the hollow cannula find gap securely.

The ultrasonic measuring head is useful in itself known manner with a passage for the hollow cannula provided. This makes it possible to use the Ultra sound measuring head in the immediate vicinity of the to insert the hollow cannula to be inserted. This has the special advantage that the measuring direction of the Ultra sound measuring head almost exactly with the puncture direction the hollow cannula matches.  

The support device expediently has a Ultrasound measuring head surrounding the hollow cannula transparent grip sleeve. This grip sleeve facilitate it helps the attending physician to safely secure the device grasp and guide and the hollow cannula during the Watch the piercing process.

The piercing process itself can be done by hand or by means of a motorized drive. For the latter case is particularly foreseen preferred embodiment of the device according to the inven tion that the support device with a motor driven feed device for the slidable stored syringe is provided, the feed path this feed device by the control signal Sonar measuring device is controlled.

An embodiment of the invention is as follows based on the drawing, the Vorrich device schematically shows in perspective view.

In the drawing, the support device is designated in its entirety by reference number 1 . The support device 1 has an elongated, hollow support body 2 , the cavity of which serves easily as a conduit for the electrical signal and power lines.

The support bracket 2 is provided at its lower end with an ultrasonic measuring head 3 , which can be placed on the upper body surface 4 of the patient above a joint gap 5 . The ultrasonic measuring head 3 is connected to a sonar measuring device 6 via cables running through the cavity of the support beam 2 . This sonar measuring device 6 is also connected to a display 7 , which is used for digital or visual reproduction of the data determined and evaluated by the sonar measuring device 6 .

At the end opposite the ultrasonic measuring head 3 , the support bracket 2 is connected to a fixed guide ring 8 , in which a replaceable disposable syringe 9 is mounted in a vertically displaceable manner. The disposable syringe 9 is provided at the lower end with a hollow cannula 10 , which can be designed either as an injection cannula or as a puncture cannula. The hollow cannula 10 runs through a passage channel 11 located in the middle of the ultrasonic measuring head 3 such that it can exit below the ultrasonic measuring head in order to penetrate into the joint gap 5 .

To move the disposable syringe in the Einichrich device of the hollow cannula 10 is used a movable syringe holder 12 which is immovably connected to the disposable syringe 9 and displaceable in the vertical direction with the support carrier 2 of the support device 1 . A push rod 13 which is driven by a drive motor 14 which is in turn attached to the support beam 2 is used for the displacement of the movable syringe holder 12 to the support beam. 2 The motor 14 is controlled by the sonar measuring device 6 so that the advance of the disposable syringe 9 and thus the hollow cannula 10 is stopped when the maximum penetration depth determined by the ultrasound measuring head 3 and the sonar measuring device 6 is reached. If the correct puncture depth is reached, z. B. by hand or with the help of a motor not shown Darge the piston of the disposable syringe 9 moves to inject the drug in the syringe ren or to suck 10 body fluid from the joint cavity via the hollow cannula.

For the purpose of safe handling of the device and in order to be able to observe the hollow cannula 10 precisely during the piercing process, the support bracket 2 is provided above half of the ultrasonic measuring head 3 with a transparent gripping sleeve 15 which surrounds the hollow cannula 10 . In the device according to the invention, the ultrasonic measuring device not only determines the maximum permissible penetration depth, but also determines the exact position of the joint gap 5 . This localization of the Ge joint gap 5 is also shown digitally on the display 7 or by an image.

In place of the disposable syringe 9 , differently designed injection or puncture pumps can also be used. In any case, however, care must be taken to ensure that the advance of the hollow cannula 10 is controlled by means of a device for limiting the penetration depth and is controlled by the sonar. Measuring device is prevented from penetrating too deep into the joint cavity.
