Definitions
- the invention relates to a bipolar coagulation and cutting device for endoscopic surgery.
- Devices of this type are tools for the surgeon to grasp tissue, to coagulate bipolarly and then to cut through the enclosed area.
- Such a combined instrument is known from the 1995 information sheet of Cabot Technology Corporaten, 2150 Cabot Boulevard West, Langhorne, PA 19047 USA.
- the instrument has a gripping device, which consists of two branches, with which tissue is coagulated along the U-shaped gripping contour. A knife is then advanced through the gripping and coagulating device and cuts through between the coagulated area.
- a combination instrument to be operated in principle in the same way is described in US Pat. No. 5,445,638. Both instruments have in common that the gripping device is also used for bipolar coagulation and then the intermediate area is severed with a mechanical means, namely a knife. This is to be carried out by the handling surgeon with a force that must be transmitted over the entire instrument.
- the invention has for its object to provide a combined instrument for endoscopic surgery with which tissue can be securely gripped and held, with which, according to the branch shape of the forceps, reliable line coagulation can be carried out at the same time and finally in the forward direction following the coagulation in the coagulated intermediate area, tissue separation in the forceps area is possible safely and with minimal effort.
- the object is achieved by a bipolar coagulation and cutting device with the features of claim 1.
- the subclaims characterize configurations with which the branches of the gripping device and the cutting device are guided in a stable and non-rotatable manner (claim 2), and the tissue cutting is additionally facilitated by the special knife-shaped shape of the cutting electrode (claim 3).
- the two leg regions of the coagulation lines can run straight, curved or undulating (claim 4).
- the two branches are parallel to each other when compressed, whereby both branches are straight or curved (claim 5).
- this hook shape provides an excellent gripping device for the vessel and tissue, which, in the case of pliers known up to now, only results from the knurling of the branches which like gripped tissue, is reached.
- the advantage lies in the fact that, in addition to the conventional gripping and coagulation process, the tissue is also cut through the action of high frequency with the cutting electrode designed for this purpose. This is a great relief, especially for small cutting lengths ( ⁇ 5 mm), since a knife cut must be made with greater tolerance because it cannot be guided so reliably and cannot be clearly seen by pushing the knife forward. The surgeon is thus relieved of force and can focus fully on the guidance of the combined instrument.
- the two pincer branches Due to the linear design of the two pincer branches, a corresponding, arbitrarily closed forward coagulation line can be embossed into the gripped tissue and the entire area can then be severed completely.
- the two branches When folded, the two branches can - 3 - Rem area of the thigh stretched, curved or, for both shapes, also wavy.
- a sensible variety is possible in the form of the branches.
- FIG. 2 shows the design of the gripping and cutting device
- FIG. 3 the closed and open gripper
- Figure 4 shows the cutting electrode in the closed and open
- FIG. 5 the tongue in the shaft end as a guide element
- Figure 6 shows the distal shaft end in plan view
- Figure 7 shows the angled distal end in plan view.
- FIG. 1 The contour of the entire instrument is shown in FIG. 1.
- the control unit On the left in the figure is the control unit with the electrical connection for the high-frequency current.
- the middle area represents the telescopic tube, the shaft, through which the transmission elements and possibly other devices necessary for the operation are guided.
- the gripping device, the pliers, with cutting device and guide tongue On the right part of the picture, the gripping device, the pliers, with cutting device and guide tongue are shown.
- Figure 2 shows the instrument in its two end positions: top in the closed state, bottom in the fully open.
- the guide tongue firmly anchored in the distal end of the shaft is omitted.
- the pliers are held over the tissue to be gripped, then the tube part (sleeve) which can be moved axially on the shaft end is advanced in order to move the two branches towards one another and to grip the tissue and finally coagulate according to the line contour of the two branches. Only then is the tube part pushed further forward in order to guide the cutting electrode through the tissue area surrounded by the coagulation line and thus cut it there.
- FIG. 3 shows the cutting electrode with respect to the shaft axis in the two end positions.
- the end region of the distal shaft end is cut open in FIG. 5 in order to emphasize the guiding property of the rigidly installed guide tongue.
- both wires for the branches are led on this side of the tongue, the wire for the cutting electrode on the other side.
- FIG. 7 shows the bent action area of the instrument, in which the work area lies next to the shaft axis and can therefore be easily seen by the surgeon.
- the materials - metallic as well as non-metallic - from which the instrument is made are tissue compatible and approved and suitable for the medical field, especially with regard to cleaning and sterilization. Furthermore, the electrotechnical structure with respect to the patient is completed in such a way that no current flows through him.
