Abstract
The present invention relates to a device developed for surgical interventions comprising (i) an inner end (1) guidable/steerable to the operation field, (ii) an outer end (3) operated by the user and (iii) a middle part (2) which connects both ends (1, 3) together. According to the main concept of the present invention, it further comprises force transmission units extending between the outer (3) and the inner (1) ends, and said force transmission units, the outer and the inner ends and the middle part (2) are designed to transfer the movements of the outer end (3) to the inner end (1) in an identical measure, as if the inner end (1) were the straight continuation of the outer end (3).
Claims18
A surgical device for surgical intervention, comprising an elongated tubular body having (i) an inner end guidable/steerable to an operation field, (ii) an outer end operable by a user and (hi) a middle part which connects said outer end to said inner end, and force transmission units extending between the outer end and the inner end, said force transmission units, together with the tubular body adapted to transfer movement of the outer end to the inner end, and including (i) a first force transmission unit adapted to transfer rotational movement of the outer end to the inner end relative to the middle part by the same rotational angle and in the same rotational direction, and (ii) a second force transmission unit adapted to transfer axial movement of the outer end to the inner end relative to the middle part by the same extent but in the opposite direction:
- and surgical instrument has a channel inside, and the second force transmission unit comprises force transmission particles connected to each other, and said particles fill in the whole length of the channel, and each of them have a hole, and through these holes of the particles travels a motive wire.
A surgical device for surgical intervention, comprising an elongated tubular body having (i) an inner end guidable/steerable to an operation field, (ii) an outer end operable by a user and (hi) a middle part which connects said outer end to said inner end, and force transmission units extending between the outer end and the inner end, said force transmission units, together with the tubular body adapted to transfer movement of the outer end to the inner end, and including (i) a first force transmission unit adapted to transfer rotational movement of the outer end to the inner end relative to the middle part by the same rotational angle and in the same rotational direction, and (ii) a second force transmissions unit adapted to transfer axial movement of the outer end to the inner end relative to the middle part by the same extent but in the opposite direction;
- and the surgical device has a channel inside, and the second force transmission unit is a sealed hydraulic unit located inside the channel, which has an outer part inside the outer end and an inner part inside the inner end.
A surgical device for surgical intervention, comprising a surgical instrument having an elongate tubular instrument body having (i) an instrument inner end guidable/steerable to an operation field and having telescopic structure, (ii) an instrument outer end operable by a user and having telescopic structure, (iii) an instrument middle part which connects said instrument outer end to said instrument inner end;
- the surgical device further comprising a trocar sleeve having an elongate tubular trocar body having a trocar inner end, a trocar outer end and a tubular trocar middle part, the tubular middle part having an outer diameter adapted to be inserted into a human or animal body containing the operation field, the trocar sleeve further having a third articulation provided between the trocar outer end and the trocar middle part and a fourth articulation provided between the trocar inner end and the trocar middle part;
- the surgical instrument being arranged in the trocar sleeve such that the instrument middle part is located in the trocar middle part;
- the trocar inner end surrounds at least partly the instrument inner end, and the trocar outer end surrounds at least partly the instrument outer end, the trocar sleeve comprising a first force transmission unit adapted to transfer rotational movement of the trocar outer end to the trocar inner end relative to the trocar middle part by the same rotational angle and in the same rotational direction, and the surgical instrument comprising a second force transmission unit adapted to transfer axial movement of the instrument outer end to the instrument inner end relative to the instrument middle part by the same extent but in the opposite direction, by elongating the telescopic instrument inner end when the telescopic instrument outer end is compressed, and by contracting the telescopic instrument inner end when the telescopic instrument outer end is elongated.
