Definitions

  • This invention concerns an apparatus for treating organic tissues such as, for example, hepatic tissue, prostatic tissue, pulmonary tissue, etc. that are to be subjected to both intraoperating and laparoscopic surgical resection.
  • organic tissues such as, for example, hepatic tissue, prostatic tissue, pulmonary tissue, etc.
  • pulmonary tissue etc.
  • different types of surgical instruments are known for the resection of tissues, such as, for example, metal scalpels, electric scalpels, electric scalpels powered by radio frequency, laser scalpels.
  • the aim of this invention is to provide an apparatus " for treating organic tissues to be subjected to both intraoperating and laparoscopic surgical resection that enables maximum flexibility of use, and, in particular, enables all the zone affected by the resection to be covered, whatever its form and/or location.
  • an apparatus for treating organic tissue to be subjected to surgical resection, comprising a body with which treatment means of said organic tissue is associated, characterised in that said treatment means comprises a plurality of treating elements arranged in an aligned configuration.
  • the treating elements may consist of electrode needles supplied with radio frequency electric power, by appropriate electrical supply means.
  • the treatment means comprises a plurality of hollow needle means, arranged in an aligned configuration, a laser optic fibre being arranged inside each hollow needle means, each laser optic fibre being supplied by an appropriate supply means. Also in this case the aligned arrangement of the needle elements with the laser optic fibre inside simultaneously enables necrotisation of the organic tissue and cauterisation of the blood vessels along the resection line identified by the aligned needles.
  • Fig. 1 is a front view of an apparatus according to the invention, in a non-operational configuration
  • Fig. 2 is a view like the one in Fig. 1, partially sectioned
  • Fig. 3 is a view like the one in Fig. 2, with the apparatus according to the invention in an operational configuration
  • Fig. 4 is a cross-section of the apparatus in Fig. 1
  • Fig. 5 is a view of a portion of organic tissue subjected to treatment with an apparatus according to the invention
  • Fig. 6 is a view like the one in Fig. 3, showing a variation of the apparatus according to the invention
  • Fig. 7 is a view like the one in Fig. 3, showing a further variation of the apparatus according to the invention.
  • the apparatus according to the invention shown in Figs. 1 to 3 comprises a body 1 that is substantially box-shaped, provided with a removable front wall 2 that is fixed to the body 1 by, for example, screws 3.
  • a support plate 4 is housed that supports a plurality of needle elements 5, each one of which has an end 6 fixed in a removable manner to the support plate 4, for example with a Luer connection.
  • the support plate 4 is provided, at its opposite ends, with a slide means 7, coupled in a sliding manner with relative slide guides 8 fixed the side walls 9 of the body 1.
  • a manoeuvring element 10 is connected, which protrudes outside the body 1, with a knob-shaped element 11 that is used to control shifts in a vertical direction of the support plate 4 to vary the length of the portion of each needle 5 that protrudes from the bottom of the body 1.
  • the manoeuvring element 10 is also used to lock the support plate 4 after said support plate 4 has been positioned in the required position, the slide 7 being connected to the respective slide guide 8 by means of rotation of the knob 11.
  • An indicator means 19 is further connected to the slide 7, the indicator means 19 emerging from a pair vertical slits 12 made in the body 1 of the apparatus, to which a graded scale 20 is associated, which, for example, indicates by how much the needle elements 5 protrude from the body 1.
  • each needle element 5 consists of electrode needle in a conductive material, the top end of which 6 is connected by a supply connector 13 and a conductor of electricity 24 to a source of electrical energy that supplies all the electrode needles 5 with radio frequency voltage, for example at a frequency of several hundred KHz, preferably about 460 KHz.
  • Each needle element 5 can be provided with a cooling means to increase the area of necrotisation along the resection lines.
  • the needle elements 5 are constituted by hollow needles within each of which an optic fibre is arranged via which a beam of laser light can be sent to the needle 5, which beam of laser light emerges from the end of the optic fibre arranged at the tip 14 of the hollow needle 5.
  • the needle elements 5 are of essentially the same length and the support plate 4 has an essentially uniform height, in such a manner that when the needle elements 5 are fixed to the support plate 4, their tips 14 are substantially aligned along a line that is substantially parallel to one side 23 of the body 1.
  • Fig. 6 shows a variation of the first version of the apparatus shown in Figs. 1 to 4, wherein needle elements 5a of differing lengths are provided that have been chosen to fix the needle elements 5a to the support plate 4, their tips 14 being substantially aligned along a line that is not parallel to said side 23 of the body 1. Said line along which the tips 14 are aligned may be a straight line, but also a curved line.
  • an apparatus according to said first version of the invention can be provided with two series of needle elements: a first series of needle elements 5, to create resections in tissues with a substantially constant depth and a second series of needle elements 5a, to create resections in tissues with a depth that increases or decreases along the selected resection line.
  • the needle elements 5 and 5a of the first and the second versions of the apparatus are interchangeable. In this way an apparatus according to the invention can be provided with both series of needle elements 5, 5a. Replacing a series of needle elements 5, 5a, with the other series of needle elements 5, 5a, is simple and rapid to achieve thanks to the "Luer lock" connections between the needle elements 5, 5a and the support plate 4.
  • Fig. 7 shows a second version of an apparatus according to the invention, wherein the support plate 4a has a height that varies in a substantially linear manner. In this way, by fixing a series of needle elements 5 of the same length to the support plate 4a the relative tips 14 are aligned along a straight line that is tilted in relation to the side 23 of the body 1.
  • a series of needle elements 5 of differing lengths is fitted to the support plate 4a the tips 14 can be aligned along a line that is parallel to the side 23 of the body 1, or along a curved line.
  • An apparatus according to the invention can be provided with just one series of needle elements 5, or 5a, and with two interchangeable support plates 4 and 4a, in such a way as to be able to obtain all the alignments of the tips 14 of the needle elements described above by simple replacement of the support plate 4 with the support plate 4a, or vice versa.
  • the needle elements 5, 5a are positioned along a first resection line 17 and are inserted into the tissue 16, whilst the electrode needles or the optic fibres are simultaneously supplied with electric power.
  • the needles are positioned beforehand by moving the support element 4, 4a in such a manner that they protrude from the body 1 of the apparatus by a sufficient amount to penetrate the entire depth of the tissue 16, along the entire resection line 17.
  • the needle elements 5, 5a consist of electrode needles supplied by radio frequency, when they come into contact with the tissue 16, inside the body tissue, between the tip 14 of each needle and the tips of the adjacent needles, radio frequency currents are established which cause progressive necrotisation of the tissue along the resection line 17 and simultaneous cauterisation of the blood vessels along said resection line 17 whilst the needles 5, 5a are penetrating the tissue 16.
  • the operation can be repeated along a second resection line 18 to completely insulate the metastasis 15 from the rest of the tissue 16.
  • necrotisation of the tissue 16 along the resection lines 17, 18 and simultaneous cauterisation of the blood vessels are caused by heating the tissue by means of the laser light transmitted via the optic fibres inserted into each hollow needle 5, 5a.
