Definitions
- the probe includes a grip member having a hollow cryogenic coolant feed line supported by said grip member open at the tip thereof and connected at one end to the cryogenic coolant supply for transmitting coolant to impinge directly upon the tissue to be frozen.
- a return line open at the tip thereof and concentrically disposed around the feed line forms a space therebetween, with means communicating said space to suction means for returning vaporized coolant from the feed supply line.
- the open end of the feed supply line is recessed with respect to the corresponding open end of the return line, allowing a cryogenic coolant to impinge directly upon the tissue to be frozen, while y'apo'rized coolant is returned through the return line.
- the ordinarily solid front end of the probe is brought into contact with the tissue to be subjected to low-temperature treatment.
- the coolant normally liquid nitrogen, is introduced into the tip of the probe by means of a feed line, vaporized at that point, and returned to the central unit by means of a return line, or released into the atmosphere from the probe.
- cryosurgical devices exhibit a disadvantage in that it is normally difficult to adapt the tip of the probe to the contour of the tissue to be treated, especially when projecting and strongly fissured proliferations are involved.
- One possibility of avoiding this disadvantage resides in maintaining probes of various sizes and shapes in readiness. However, this is very cumbersome and expensive and does not meet all situations occurring in practice.
- this invention provides a novel cryo surgical device, the probe of which does not have the above-mentioned disadvantages and which can furthermore be exchanged in a simple manner with probes of a different type of construction connected to a central supply unit.
- the probe tip consists of two concentric tubes, wherein the front end of the inner tube is recessed with respect to the front end of the outer tube. Thereby, a chamber is produced within the outer tube which can be filled by the coolant fed by the inner tube. Accordingly, when such a probe is applied to the tissue to be treated, only the .rim of the outer tube need be in contact with the tissue, and the surface of the tissue to be treated is completely under the effect of the coolant, independently of the shape of the tissue.
- the inner tube exhibits a vacuum jacket at least in the rear section thereof. This prevents outside heat from contacting the coolant, which would result in an undesired cooling of the entire device and an unnecessary consumption of coolant.
- the grip member can consist of a preferably sectioned housing and can be provided with a handle exhibiting a trigger.
- the grip member can be detachably connected by a connection line to a central unit. In this case, it is possible to attach different-type grip members with probes to a suitable connection line.
- connection lines between the grip member of the probe and the central unit are preferably concentrically arranged corrugated tubes detachably joined to the central unit by means of a coupling section.
- connection lines for the supply of a probe with a coolant is disclosed for example in the US. Pat. No. 3,220,414.
- FIG. I is a schematic view, partially in cross-section, of a probe of this invention.
- FIG. 2 is a cross-sectional view of a probe having a conventional trigger, valving member and control means incorporated therein;
- FIG. 3 is a cross-sectional view of a probe illustrating a corrugated connection line and electrical control lines.
- a tube 1 preferably consisting of stainless steel, serves as the feed line for the coolant which is preferably liquid nitrogen; this tube 1 is surrounded, in its rear portion, by a vacuum jacket 2, by means of which cold losses and thus a premature warming and evaporation of the coolant are avoided.
- the vacuum jacket 2 can be evacuated by the disconnectable nipple 2a.
- the front end of the feed tube ll consists of a solid metallic part 3 which is likewise normally made of stainless steel.
- a return tube 4 is arranged concentrically about the feed tube 1 with vacuum jacket 2 this return tube is fixedly joined in the rear section with the probe shank 5, which latter consists preferably of polytetrafluroethylene, and the front end of the return tube exhibits a mounting 6, provided with openings, for the feed tube 1.
- the free space present in the outer end can be reduced or enlarged, and the distance between the point of exit of the coolant from the tube 1 and the tissue to be treated can be varied. Due to the fact that the outer return tube sleeve 7 consists of a transparent material, it is possible for the operator to closely observe the processes in the probe, in particular to determine the amount of coolant which is still in the liquid phase and has not yet evaporated at the site of application.
- An electric heating element 10 is disposed in the probe shank 5 within a metallic jacket 9, which element serves for heating the recycled coolant to room temperature.
- This element is preferably thermostatically controlled.
- the thermostat for this device (not shown) can be arranged directly behind the heating device in the grip member 12, or at some other place in the return line, for example within the central unit.
- the tube 4 is mounted to a hollow-cylindrical shank of a larger diameter detachably joined to the grip member 12, preferably, by means of a threaded section 1 ll, facilitating the exchangeability of the tip of the probe.
- This exchange possibility is of particular advantage, since, on the one hand, when the tip of the probe has been damaged, only the tip need be replaced, and, on the other hand, when probe tips of different lengths and different thicknesses are required for different purposes of application, only the probe need be interchanged.
- the grip member 12 is composed of two parts 121: and 12b and can be disassembled along the parting line 13 after the release of fastening elements (not shown). This facilitates the servicing and repair of the elements contained in the grip member.
- the grip member 12 is provided with a handle 14 in which a trigger 15 is installed.
- valve 16 is disposed in the grip member, which valve is mechanically connected with the trigger 15 and can be operated by means of the latter.
- This valve can have a cone valving member of conventional design which serves as a metering valve when lifted mechanically.
- the valve member can furthermore be fashioned so that it can be lifted against the force of a spring by the excess pressure of the coolant. In this case, the valve has the effect of a safety valve in the feed line for the coolant.
- the feed line for the liquid coolant for example, liquid nitrogen
- the feed line for the liquid coolant consists of a corrugated pipe 18, preferably made of stainless steel, surrounded by another corrugated pipe 19 of the same construction, but having a larger diameter. Between the two pipes there is an evacuated space 20. Yet another corrugated pipe 21 is arranged concentrically and in spaced relationship to the corrugated pipe 19.
- the pipe 21 consists of a soft resilient material such as plastic and is supported by a coil spring.
- the pipe 21 forms an annular duct 22 of a relatively large cross-section for the gaseous coolant flowing back to a central unit (not shown) which coolant is warmed approximately to room temperature.
- This coolant is taken in by a suction fan (not shown) arranged in the central unit.
- the space is evacuated in order to prevent the transfer of heat thereto, and electric lines (not shown) are installed in the duct 22 between the outer corrugated tubes wherein the warmed returned gas is flowing.
- the connection lines terminate in a coupling section detachably joined to the central unit.
- FIG. 2 an inlet portion 1a and an outlet portion lb of feed tube 1 can be seen which are in communication with one another via inlet chamber 23a and outlet chamber 23b.
- the inlet chamber 23a is sealed against the inner part of handle 14, while using a corrugated pipe 24 welded to valve body 36 and to valve stem 25.
- trigger 15 is pressed into the inner part of the handle 14 against the force of a spring 26
- one or more microswitches 27 are first activated and valve stem 25 is then lifted against the force of spring 28.
- the microswitches 27 can operate relays, valves, or the suction fan in the central supply unit as desired.
- valve stem 25 When valve stem 25 is lifted, a valve cone 29 is simultaneously lifted from a valve spring seating 30, and liquid nitrogen passes from inlet portion 1a through inlet chamber 23a to outlet chamber 23b and thence through outlet part 1b.
- Centering means 31 allows a centered lifting of valve cone 29 against spring 28 which is held in a turnable valve cup 32, with which the force of spring 28 can be regulated.
- Valve 16 is surrounded by an evacuated chamber 2.
- Trigger 15 and microswitches 27 are mounted on a mounting plate 33 which can be welded to valve body 36. Electric lines 34 coming from the microswitches 27 and going to the central supply unit can have a plug connection 35 at each side of the connection line and are spirally wound around a corrugated pipe 19.
- FIG. 3 shows one coupling system between grip member 12 and the connecting line, which may also be used as a coupling system between the connecting line and the central supply unit.
- Conventional corrugated pipes 18 and 19 form an evacuated space 20, in which there is a spirally wound spacer 40, conveniently of plastic material, to maintain the distance between the corrugated pipes 18 and 19.
- a part 44 At the end of corrugated pipe 18 is welded a part 44, while at the end of the corrugated pipe 19 is welded a part 37; both parts 44 and 37 are welded together to sealingly enclose one end of evacuated space 20.
- Corrugated pipe 21 is formed of a plastic tube fitted with a spring coil 45.
- An annular duct 22 is formed between corrugated pipe 19 and corrugated pipe 21, the latter being surrounded by a fitted screw cap 17 with a sealing device 42.
- electric lines 34 are spirally wound around the corrugated pipe 19. These electric lines 34 can be connected to an electric system in either the grip member 12 or the central supply unit by means of plug connections 35 such as shown in FIG. 2.
- plug connections 35 such as shown in FIG. 2.
- parts 44, 37, 38 are slid onto parts 43 and 39 of valve 16.
- the corrugated pipe 21 is turned into the space between grip member 12b and part 41, fixed by means of screw cap 17, and sealed by sealing device 42.
- annular heating device 23 is provided which is firmly connected to the front rim of the return tube sleeve 7 or can be placed thereon; this heating device is operable by means of a push button 24 likewise disposed in the handle 14. In this manner, it is possible to remove the tip of the probe, frozen fast to the tissue to be treated, in a rapid and easy fashion.
- the feed lines for this heating device can also be laid within the flow path for the returning gas.
- the mode of operation of the device of this invention is as follows:
- the probe is firmly placed on the tissue to be treated with the front rim of the outer return tube sleeve 7. Then, by actuation of the trigger 15, an electric circuit is initially closed, which circuit opens a magnetic valve (not shown) in the central unit, whereby pressurized liquid nitrogen is conducted through the corrugated pipe 18 to the valve 16 in the grip member 12. At the same time, the suction fan provided in the central unit is started, whereby the tissue to be treated is drawn against the rim of the outer return tube sleeve 7 and somewhat into this tube. Upon a further depression of the trigger 15, the cone valve member of the valve 16 is lifted, by means of a suitable mechanical transmission (not shown) in dependence on the extent to which the trigger 15 is depressed.
- the liquid coolant can pass through the feed tube 1 and can exit through the front end 3 thereof, and impinge on the tissue to be treated.
- the return tube sleeve 7 can be telescopically moved on the tube 4 at any time to adjust the proximity of the tip of the tube 1 to the tissue as desired.
- the largest portion of the thus-supplied liquid nitrogen is vaporized during this process.
- the gaseous nitrogen is returned in return tube sleeve 7 and passes through the openings in the mounting 6 and through the tube 4 to the heating device 10 wherein it is warmed to room temperature or about C.
- the gaseous nitrogen then flows on through the grip member 12 into the space 22 formed between the corrugated pipes 19 and 21 and passes in this hallow space to the exhauster of the central unit and from there to the outside.
- the valve in the central unit and the valve 16 in the grip member are closed and the suction fan is cut off.
- the conduit 18 is, however, still filled with liquid coolant. If the probe is not operated for an additional period of time and a portion of the liquid gas remaining in line 18 evaporates, the pressure in this line will rise. in order to avoid any damage to the apparatus thereby, the valve 16 is fashioned as a safety valve in such a manner that the valve cone is lifted against the force of a spring by the pressure of the medium present in line 18, and the medium can then exit through the tip 3 of the feed line 1. In case the probe tip is still resting on a counter surface and the exiting coolant thus cannot freely be released, the gaseous medium can readily flow off through the return line, even if the suction fan is not on.
- the suction fan in the central unit need not be actuated only upon opening of the magnetic valve in the control device and of the valve 16 in the probe; rather, it can if so desired, be run continuously, On the other hand, it can also be advantageous to provide means to cut off the blower even when both valves are opened.
- the probe of the device of the present. invention can also be provided with a conventional endoscope, if it is necessary to employ the tip of the probe at places which are not readily accessible optically.
- a cryogenic probe including a grip member having a hollow cryogenic coolant feed line supported by said 'grip member, said line being open at the tip thereof and connected at one end to said cryogenic coolant supply for transmitting liquid coolant to impinge directly upon tissue to be frozen;
- a hollow cryogenic coolant return line open at a transparent end thereof concentrically disposed around said feed line to form a space therebetween;
