Definitions
- the subject of this invention shall be a circular knife of a suturing instrument, performing arbitrary helical (simultaneous axial and rotary) movement to provide a tissue protective surgical section of the intestine ends when making mechanical circular enterorrhaphy to allow thereby the reduction in the risk of injury of the suture and occurence of sutural insufficiency, that according to an advantageous implementation has a rod provided with spiral and pin-hole located in the suturing head, a circular knife provided with a base fitted with spiral thread precisely adopted to said spiral, and rollers facilitating the movement of the spiral and the spiral thread along each oder in a bearing-like way.
- Circular enterorrhaphy is highly preferred, first of all, in anatomically difficult areas. When used properly, they are suitable for providing reliable enterorrhaphy within a short time. When used for enterorrhaphy purposes, the exclusive axial movement of the currently used circular knives built in the suturing head may be problematic, because such circular knives are destructive when cutting the tissue and thereby they jeopardize the reliability of enterorrhaphy, contributing thereby to the development of sutural insufficiency. Any insufficiency of a suture may result in a complication perilous to life. One of the most important purposes of suturing instruments subject to an ongoing upgrading will be to make an enterorrhaphy under a trauma as low as possible.
- the modified suturing instrument described in USA Patent No. 4.907.591 also has a circular knife performing rotary movement.
- the rotary movement begins only at the end of the axial movement, after the circular knife has reached the tissues, thereby the tissue dissection becomes more traumatic.
- the circular knife of the present invention performs helical (simultaneous axial and rotary) movement before reaching the tissues, and according to an advantageous implementation it dissects the tissues with at least 60° rotation, providing thereby -in contrast to the cited invention- a more protective surgical section of the tissues.
- the object of the invention is to develop a circular knife to reduce the risk of sutural insuffieciency, wich allows a cautious surgical section of the involved parts of the intestines instead of destructive section when making intestinal sutures, to reduce thereby the rise of sutural insufficiency.
- This invention is based on the recognition that the application of a circular knife, that already performes helical (axial and rotary) movement continuously before reaching the involved tissues and according to an advantageous implementation makes at least 60° rotation, will make possible to cut the tissues in a cautious and gentle way.
- the set objective will be solved by application of a circular knife making arbitrary helical (simultaneous axial and rotary) movement, located in the head of the circular suturing instrument, that according to an advantageous implementation has a rod fitted with spiral and pin-hole, a circular knife provided with a base fitted with spiral thread fitted precisely to said spiral, and rollers facilitating the movement of the spiral and spiral thread along each other.
- the rod located in the suturing head is fixed to the suturing instrument.
- the pin-hole of the rod will locate the up and down moving pin or sleeve required for connecting the suturing head and the anvil (not shown on the figures) together.
- the slope and direction of the spirals on the rod are adopted and fitted to the spiral threads in the base.
- the side of the spiral threads in the base is provided with embedded rollers to facilitate the movement of the circular knife.
- the circular knife is fixed to the base.
- any other known solution eg: mechanic, hydraulic, pneumatic, electromotoric, etc.
- mechanic, hydraulic, pneumatic, electromotoric, etc. is considered to be part of the present invention, that allows the former described movement of the circular knife.
- Figure 1/A shows the rod provided with spiral and pin-hole
- Figure 1/B shows the base provided with spiral threads and the circular knife fixed to it
- Figure 1/C shows the rollers embedded in either side of the spiral threads in the base
- Figure 2/A shows the circular knife of the currently used sutural instruments suitable only for cutting function, and the incised, lacerated wound produced by such knife,
- Figure 2/B shows the circular knife suitable for cautious tissue section, that performs arbitrary helical movement, and shows the incised surgical wound made thereby.
- the sutural head provided with a circular knife performing arbitrary helical movement as set out herein will function in a manner as follows:
- the most important advantage of the solution according to this invention shall be that it ensures a tissue protective surgical section of the concerned parts of the intestines when suturing the intestines, including a reduction in laceration of the intestinal sutures making possible thereby a reduction in risk of sutural insufficiency.
