The present invention relates, in general to a surgical device and more particularly, to a surgical device having a jaw insert, outer tube, and handle which are detachable and reusable and/or disposable, the jaws seal the vessels/tissue and the cutter cuts the vessel/tissue electrically.
Numerous bipolar electrosurgical forceps have been proposed in the past for various surgical procedures. Many of these instruments include blade members or shearing members which simply cut tissue in a mechanical and/or electromechanical manner and are relatively ineffective for vessel sealing purposes.
Other instruments rely on clamping alone to procure proper sealing thickness and are not designed to take into account gap tolerances and flatness requirements which are parameters which, if properly controlled, can assure a consistent and effective tissue seal.
In mechanical cutters, the cutting achieved is not sharp and clean, the blade can become distorted/blunt after multiple use, disposable parts are more in the device.
In electrically used cutter less force is used for cutting allowing smoother cutting, mechanical complications are less assembly wise which is simplified and device life increases.
Further, in existing devices, jaws do not allow vapors/steam generated in the sealing process to pass which decreases seal strength.
In spite of available devices and techniques, there still exists a dire need to provide a bipolar surgical device that consists of jaws comprising of sealer with cutter that is capable of sealing and/or cutting of the tissue and/or vessel.
Accordingly, the following invention illustrates a bipolar surgical device that consists of jaws comprising of sealer with cutter that is capable of sealing and/or cutting of the tissue and/or vessel.
An aspect of the present disclosure relates to a bipolar surgical device having a jaw insert (7) having jaws (4) connected to an outer tube (3). The jaw insert (7) and said outer tube (3) are connected to a handle (2) having at least one enclosed part (8) operating as a jaw driving mechanism and operatively coupled to a trigger (1). The jaws (4) closed when said trigger (1) is pressed and said jaws (4) open when said trigger (1) is not pressed. The handle (2) consists of two buttons (6, 7′) where a first button (6) is used for sealing tissue and/or vessel when pressed, and said second button (7′) is used for cutting of the tissue and/or the vessel when pressed.
In an aspect, the jaw insert can be cleaned and/or autoclaved after it is disassembled from the outer tube or it can be replaced.
In an aspect, the outer tube can be disassembled and can be cleaned and/or autoclaved after it is disassembled and can be reused or it can be disposed.
In an aspect, said handle (2) includes a first contact pole (9), a second contact pole (10) and a third contact pole (11). In another aspect, the first contact pole (9) causes an electrical conduction on a first insert contact (18) of the jaw insert (7), the second contact pole (10) causes an electrical conduction on a second insert contact (17) of the jaw insert (7), and the third contact pole (11) causes an electrical conduction on the third insert contact (16) of the jaw insert (7). In yet another aspect, the first contact pole (9) and the second contact pole (10) causes sealing of the tissue and/or vessel while the third contact pole (11) causes the cutting effect. In still another aspect, said first contact pole (9), said second contact pole (10) and said third contact pole (11) are separated by insulators (15)
In an aspect, said handle (2) includes threaded joint (23) in which said outer tube (3) and said jaw insert (7) are detachably coupled to said handle (2).
In an aspect, said jaws (4) comprises an upper jaw (19) and a lower jaw (20) separated by spacers (22) allowing space between said upper jaw (19) and said lower jaw (20) when the jaws (4) are closed, wherein said upper jaw (19) and said lower jaw (20) are used for sealing of the tissue and/or vessel.
In an aspect, said upper jaw (19) or said lower jaw (20) includes a cutter (21) used for cutting the tissue and/or vessel.
The following invention illustrates a bipolar surgical device that consists of jaw assembly comprising of sealer jaws with cutter that is capable of sealing and/or cutting of the tissue and/or vessel.
Jaw of another shape can be used which can be straight, round, curved or any other shape without any limitation.
The first and second contact pole causes sealing of the tissue and/or vessel while the third contact pole causes cutting effect.
Minimum two contact poles needed to deliver bipolar energy delivery path. This device has 3 poles and can be increased by adding more number of poles. Various effects can be created by multiple poles or change effect of device.
Alternatively the jaws 19 and 20 can be used for sealing without the cutter 21 in between. Alternatively only the cutter 21 can be used for cutting.
In an embodiment, the jaws/electrode can have non sticky/superconductive coatings or can be made of superconductive materials or have special chemical coatings for improved results. Electrodes can be made up of nonconductive material with conductive coating on the surface The device can be used for variety of laparoscopic surgical procedures without limitation.
