Description

Anti-slip ligation appliance for abdominal cavity minimally invasive surgery

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to an abdominal cavity minimal access surgery antiskid takes off ligature utensil.

Background

In minimally invasive abdominal surgery, diseased human tissue (such as the intestine) needs to be excised and removed from a minimally invasive opening; in the process of resection, the diseased tissue needs to be drawn to a proper position or a proper angle, and the position of the diseased tissue needs to be fixed; removal of the diseased tissue from the incision in the abdominal wall is generally required after resection, and when the diseased tissue passes through the incision, it must be ensured that the diseased tissue does not slip out, due to the small incision. For the above reasons, it is necessary to tightly ligate the lesion tissue in the minimally invasive surgery (commonly known as banding, also known as ligation in the row).

The traditional ligature mode adopts the nylon rope to tie up pathological change tissue and knot, however, the operation of knoing is difficult under the peritoneoscope to the effect that the knot is difficult to reach and compacts (as is known, the knot need make twice at least, wherein first knot still just realizes preliminary tightening easily, nevertheless when carrying out the operation of second after first completion knot, the first knot that has originally tightened up tentatively can loosen owing to the bounce of being tied up the object, leads to final second knot to reach and compact).

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned shortcoming and provide an abdominal cavity minimal access surgery antiskid ligature utensil, it can implement to tie up human tissue at the minimal access surgery in-process, and tie up to compact firmly, and the operation is light convenient.

The purpose can be realized according to the following scheme: an anti-slip ligation device for an abdominal minimally invasive surgery is characterized by comprising a hollow circular metal sleeve and a circular plastic strip, wherein a binding ring is formed at the tail end section of the plastic strip, a binding hole is formed in the middle of the binding ring, a plurality of conical protrusions are formed in the middle section of the plastic strip, the conical protrusions are identical in size and shape and are distributed in a long direction of the plastic strip, and a deformation hole is correspondingly formed in the middle of each conical protrusion; the aperture of the bundle hole of the plastic strip is smaller than the diameter of the large end of the conical bulge; the inner diameter of the tube cavity of the round metal sleeve is larger than the diameter of the large end of the conical convex part of the plastic strip, the length of the round metal sleeve is smaller than that of the plastic strip, and the diameter of the head end part of the plastic strip is smaller than the aperture of the bundle hole of the plastic strip.

Preferably, the cross section of the deformation hole is in a cross shape.

The large end of the conical projection is the end of the conical projection with the larger diameter. The conical projection is temporarily deformed while passing through the beam hole. The large end diameter of the conical projection means a large end diameter of the conical projection in a natural state when the conical projection is not deformed.

The utility model has the advantages of it is following and effect:

the utility model discloses can implement to tie up human tissue at abdominal cavity minimal access surgery in-process, and tie up to tighten firm, the operation is light convenient, can conveniently pull suitable position and angle after tying up, shortens the operation time.

Detailed Description

An anti-slip ligation device for an abdominal cavity minimally invasive surgery, which is shown in fig. 2, 3, 4, 5, 6, 7 and 8, comprises a hollow circular metal sleeve 3 and a circular plastic strip 1, wherein a binding ring 14 is formed at the end section 13 of the plastic strip, a binding hole 15 is formed in the middle of the binding ring 14, a plurality of conical protrusions 2 are formed at the middle section 12 of the plastic strip, the conical protrusions 2 are the same in size and shape, the conical protrusions 2 are distributed along the longitudinal direction of the plastic strip 1, a deformation hole 10 is correspondingly formed in the middle of each conical protrusion 2, and the cross section of each deformation hole 10 is cross-shaped. The diameter of the plastic strip hole 15 is smaller than the diameter of the large end of the conical protrusion 2 (the diameter of the large end of the conical protrusion 2 refers to the diameter of the large end of the conical protrusion in a natural state when the conical protrusion is not deformed, as shown in fig. 4, the diameter of the large end of the conical protrusion 2 is an EF end, and thus the diameter of the large end of the conical protrusion 2 refers to the diameter of the EF); the inner diameter of the tube cavity of the round metal sleeve 3 is larger than the diameter of the large end of the conical convex part 2 of the plastic strip, and the length of the round metal sleeve 3 is smaller than that of the plastic strip 1; the diameter of the plastic strip head end section 11 is smaller than the diameter of the plastic strip bundle hole 15.

The principle of use of the above embodiment is as follows:

in the operation process, the whole plastic strip 1 is placed into the abdominal cavity through the abdominal wall incision 80 and wound around the diseased tissue 8, the head end section 11 of the plastic strip is firstly penetrated into the bundle hole 15 of the plastic strip to tie the diseased tissue 8, then the middle section 12 of the plastic strip is pulled to gradually penetrate through the bundle hole 15, and then the plastic strip 1 is gradually tightened and finally tied tightly, as shown in fig. 1; then, the section near the outside of the plastic strip is pulled out of the abdominal cavity wall 81, the circular metal sleeve 3 is sleeved with the plastic strip 1, the bottom end of the circular metal sleeve 3 enters the abdominal cavity and is close to the binding ring 14 of the plastic strip, then the plastic strip 1 can be pulled by the circular metal sleeve 3, and further the lesion tissue 8 is pulled, so that the lesion tissue 8 reaches a proper position and angle, as shown in fig. 1, then, the excision is performed, and the excised lesion tissue 8 can be pulled out of the abdominal cavity wall incision 80 by the plastic strip 1.

In the above process, when a specific conical protrusion 2 of the plastic strip passes over the binding hole 15, the deformation hole 10 of the conical protrusion is deformed and narrowed, and the deformed and narrowed state is as shown in fig. 9, i.e. the cross section of the conical protrusion is reduced, so that the diameter of the conical protrusion 2 is temporarily reduced to easily and smoothly pass through the binding hole 15; after the conical convex part 2 passes through the binding hole, the deformation hole 10 corresponding to the conical convex part 2 restores the natural shape again, the diameter of the conical convex part 2 restores the natural shape, and the diameter of the large end of the conical convex part 2 restores to the normal state larger than the aperture 15 of the binding hole, so that the plastic strip 1 can not retreat relative to the binding ring 14 any more, which means that once the binding is tightened, the plastic strip can not loosen and is very firm.
