TECHNICAL FIELD

The present disclosure relates to the field of suturing instrument. In particular, the present disclosure pertains to the suturing instrument that enables control of a suturing needle during operation for suturing tissue.

BACKGROUND

Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

Laparoscopic or Robotic Suturing body tissue is a time-consuming aspect of many surgical procedures. Needle holders typically include a textured tip for a secure hold. Usually, the needle holder has a ratchet for locking.

However, application of these type of suturing instruments are limited by the manner in which they access the areas of the human body in need of repair. In particular, the instruments may not be able to access tissue or organs located deep within the body or that are in some way obstructed. Also, many of the instruments are limited by the way they grasp tissue, apply a suture, or recapture a needle and suture. Furthermore, many of the instruments are complicated and expensive to produce due to the numerous parts and/or subassemblies required to make them function properly.

In addition, such type of suturing instruments requires a long learning curve. In other words, the existing surgical instrument are difficult to operate. Further, as operating space for the surgery is very minimal in Laparoscopic/Robotic surgeries, needle may prick the surrounding structure causing abrupt bleeding, bowel and bladder perforation or adjacent organ injury. Furthermore, losing the needle in the abdominal cavity leads to complication.

Therefore, there is a need of an improved suturing instruments that can overcome above-mentioned challenges in the art.

In an embodiment, the knotting unit 110 can comprise a rack and pinion mechanism coupled to a third lever 111. In another embodiment, the lever 111 can be configured with serrations to form rack part of the rack and pinion arrangement, and a circular gear like structure 201 forms pinion part of the rack and pinion arrangement. Further, and a semicircular member 202 can be operatively coupled to the rack and pinion mechanism, wherein the rack and pinion mechanism convert linear motion of the third lever 111 into rotary motion for moving the semicircular member 202 around a fixed center 203 in order to move the second suture 106-2 forward for suturing operation. The third lever 111 can be coupled to the second stitching arm 107-2 such that opening and closing of the stitching arms 107 moves the third lever 111 linearly in forward and backward direction thereby facilitating the suturing operation. The second suture 106-2 can be firmly fixed to the fixed centre 203 to draw the second suture 106-2 from the suture roll. In an embodiment, encasing rubber caps can be used to fill up space between the enclosure 105 and jaws 107 during contraction phase of the jaws 107.

FIGS. 3A-3D illustrate suturing operation of the proposed suturing instrument, in accordance with embodiments of the present disclosure.

In an embodiment, on closing the handles 101, both the jaw contracts. The needle 204 lowers and penetrates the tissue, carrying first suture 106-1 with it. The needle 204 thus enters the knotting unit 110 in the second stitching arm 107-2 (as shown in FIG. 3A). In an embodiment, the semi-circular-rotating member 202 can hook to the first suture 106-1 present in the needle 204 by its mouth and continues to turn around the fixed centre 203 by dragging the first suture 106-1 (as shown in FIG. 3B). Opening and closing of the stitching arms 107 moves the third lever 111 linearly in forward and backward direction to provide forward movement to the second suture 106-2. In an embodiment, during the course of rotation of the semi-circular-rotating member 202, the first suture 106-1 grasped in the mouth of the semi-circular-rotating member 202 carries like loop of thread around it and as the needle slowly rise above the tissues, making its own suture tout which aids in easy knotting and also preventing the coiling of suture within the knotting unit 110 (as shown in FIG. 3C). In an embodiment, at the end of the semi-circular movement of the semi-circular-rotating member 202a lock knot can be formed and on releasing/opening the handles 101, the semi-circular-rotating member 202 reverts back to its normal position and so the needle 204. The stitch is now ready to be repeated (as shown in FIG. 3D).

At the starting and ending points of suturing, 2-3 sutures are applied at the same point for securing.

In an embodiment, the tissue can be any one or a combination of muscles or fascia.

Thus, the proposed suturing instrument may offer several advantages over conventional suturing instrument used by surgeons in surgeries such as laparoscopic, robotic surgeries for suturing tissue in that it provides a hand-held suturing instrument with relatively simple mechanical construction. The present disclosure provides relative ease of operation for the surgeon with only one hand, thereby enabling the surgeon to move obstructing tissue, debris and biological fluids from the suturing site with a free hand, while eliminating the need for needle holders, pick-up forceps, and other tools normally required for suturing by hand.

In addition, the proposed suturing instrument reduces the time required for the surgery. The instrument may also helpful because of its compact size in minimal access surgeries like laparoscopic and robotic surgeries, where there will be limited operating space. The proposed surgical instrument may be used in different surgical branches such as but not limited to general surgery, Gynecological surgeries, bariatric surgery, Gastro-intestinal surgeries and all open surgeries.

In an exemplary embodiment, diameter of the suturing instrument may be 10 mm. Particularly, when the suturing instrument needs to be inserted into the abdominal cavity through a 12 mm diameter cannula, the diameter of instrument may be 10 mm.
