Methods, systems, and devices for surgical suturing
Various exemplary methods, systems, and devices for surgical suturing are provided. In general, a loading element can be configured to facilitate loading of a plate into a surgical instrument configured to facilitate passage of a suture through tissue. The surgical instrument can be configured to advance the suture through a tissue of a patient, to capture a free end or looped end of the suture after the suture's advancement through the tissue, and to pull the captured suture out of the patient's body with a portion of the suture remaining passed through the tissue within the patient's body.
1. A surgical system, comprising:
an outer member having an internal cavity therein and having proximal and distal ends, the proximal end of the outer member having an opening therein that is in communication with the internal cavity; and
an inner member having proximal and distal ends and being an independent element from the outer member, the distal end of the inner member being configured to be inserted through the opening of the outer member and into the internal cavity of the outer member, the inner member including a seat configured to removably and replaceably receive a plate therein, the proximal end of the inner member having a bore formed therein, the bore being configured to receive therein a distal end of a surgical instrument, wherein the inner and outer members are configured to cause the plate to advance into the bore from the seat in response to the inner member being inserted into the internal cavity.
2. The system of claim 1 , further comprising a plate configured to removably and replaceably be received in the seat, the plate being configured to facilitate manipulation of a suture.
3. The system of claim 1 , wherein the outer member has an internal protrusion that extends into the internal cavity, the internal protrusion being configured to push the plate into the bore from the seat.
4. The system of claim 1 , wherein the inner member has a single position relative to the outer member in which the inner member is configured to be inserted through the opening of the outer member and into the internal cavity of the outer member.
5. The system of claim 1 , wherein the inner and outer members have corresponding engagement members configured to orient the inner and outer members relative to one another in a predetermined orientation.
6. The system of claim 5 , wherein the engagement member of one of the inner and outer members includes a slot, and the engagement member of the other of the inner and outer members includes a protrusion configured to slide within the slot during the advancement of the inner member in the distal direction into the internal cavity.
7. The system of claim 1 , wherein the inner member has a slot formed in an external surface thereof, the slot having an open proximal end and a closed distal end.
8. The system of claim 1 , wherein the inner member includes a stop element configured to stop movement of the inner member in the distal direction within the internal cavity once the inner member has advanced a predetermined amount into the internal cavity.
9. The system of claim 1 , wherein the inner member has one or more ribs formed on a top surface thereof.
10. The system of claim 1 , wherein in response to the plate being fully advanced into the bore from the seat, at least one of the inner and outer members is configured to generate at least one of an audible confirmation and a tactile confirmation of the full advancement.
11. The system of claim 1 , further comprising a surgical instrument having a distal end configured to be received within the bore of the inner member, wherein the inner and outer members are configured to cause the plate to advance from the seat into the distal end of the surgical instrument within the bore of the inner member.
12. The system of claim 11 , wherein the distal end of the surgical instrument includes a pair of jaws configured to move between open and closed positions.
13. The system of claim 11 , wherein the distal end of the surgical instrument is configured to be inserted into the bore of the inner member in a single predetermined orientation relative to the inner member.
