Definitions
- the invention is related to a surgical device for application in a treatment performed on the human or animal body with the aim of providing access to a surgical site in said body, comprising expansion means suitable for exerting a force on the organs and/or tissues at said surgical site, e.g. for mobilising and/or supporting said organs and/or tissues, upon expansion of said device at the location of the surgical site, at least one fluid reservoir as well as means for conveying fluid from said reservoir to the expansion means with the aim of expanding said expansion means.
- expansion means suitable for exerting a force on the organs and/or tissues at said surgical site, e.g. for mobilising and/or supporting said organs and/or tissues, upon expansion of said device at the location of the surgical site, at least one fluid reservoir as well as means for conveying fluid from said reservoir to the expansion means with the aim of expanding said expansion means.
- expansion means suitable for exerting a force on the organs and/or tissues at said surgical site, e.g. for mobilising and/or supporting said organs and/or tissues, upon
- the expandable tip itself consists of a generally hollow inflatable device member similar to a balloon. It is fabricated from a non-toxic, relatively strong, flexible and resilient material such as polypropylene or a similar type of impervious material which is flaccid and deformable in the unexpanded state.
- the internal space of said balloon type member can be inflated by either introducing a liquid or a gas therein.
- Said prior art surgical device has several disadvantages. Due to the elastic character of the balloon type member, an energy build up occurs during expanding the balloon.
- a further disadvantage of the prior art surgical device is related to the balloon shape thereof. Although a somewhat better access to the surgical site can be obtained thereby upon expansion, it nevertheless also has a shielding effect with respect to the directly adjoining tissues or organs. In those cases, the expansion member has to be moved out of the way, which complicates the surgical operation.
- the object of the invention is to provide a surgical device of the type described before which does not pose the risk of causing trauma, even in the case of an inadvertent failure of the expansion means.
- a further object is to provide a surgical device which allows a better access to the surgical site in question.
- the expansion means comprises a sheet type material having a relatively low bending stiffness and a relatively high in-plane stiffness.
- the expansion means according to the invention can be stowed into a small package, as a result of the bendable character of the material thereof. Upon expansion however, it will not stretch as a result of the high in-plane stiffness thereof. Thus, the expansion means itself will not store energy itself, as it does not, or hardly not, stretch.
- the expansion means comprises at least one elongate expansion member which has a longitudinal shape in the expanded state.
- the expansion means has at least two elongate expansion members which are angled with respect tot each other's longitudinal direction in the expanded state.
- the expansion means comprises at least one tension member the length of which is smaller than the sum of the lengths of the elongate expansion members, the expanded device will obtain a predetermined, desired shape which is prescribed by the dimensions of the various members. It will be clear that the expansion members will then delimit a specific open area, which allows a better accessibility of the enclosed area.
- at least three elongate expansion members can be provided which together constitute a triangle.
- the frame thus obtained may further be used to form expansion means having specific height, length and width dimensions.
- the multiple elongate expansion members thus applied may constitute a spatial structure.
- a tetrahedron is given, but other structures such as a cube and the like are possible as well. All these structures have in common that they offer a frame after expansion of the several expansion members, which to that end preferably have interconnected fluid chambers allowing a simultaneous expansion.
- the frames thus obtained are able to create a free space within the body at the surgical site. The surgeon is thus able to reach through the open sides of the expanded frame, and is therefore able to perform intricate operations at the site without being hampered by the expansion means itself.
- the surgical device comprises at least one restrictor for restricting the expansion of the expansion means.
- the expansion means in question can be urged into a specific, prescribed shape, for instance a curved shape.
- the restrictor comprises a tension member, in particular a pull member.
- the fluid reservoir comprises a container 4 which holds an amount of preferably liquid, which by means of pump 5 is pumped into the line 6.
- the line 6 in turn is connected to a connection port 7, which gives access to the internal space of the expansion means 1.
- Said expansion means comprises six elongate members 8, which together constitute a tetrahedron.
- the elongate expansion members 8 are connected to each other at the notes 9.
- the expansion members contain a fluid chamber 10, which fluid chambers 10 at the location of the notes 9 are interconnected. In a rest state, the elongate members 10 are deflated, which means that they can be reduced to relatively small dimensions for introduction at a surgical site.
- a fenestration hole 13 is provided in said flexible web 12 so or to enable the surgeon to reach the surgical target site. Further webs 12 may be mounted to the other expansion member 8 as well.
- Figure 2 shows a possible embodiment of a tension member 8 provided with a pull member 14.
- the pull member 14, e.g. wire, is connected to the opposite ends of the tension member 8.
- the length of the pull member 14 is somewhat smaller than the length of the tension member 8 between the mutual connection points.
