Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to Nice knot ligature leading-in needle.
Background
The Nice knot was invented by the french shoulder gird Pascal doctor and named Nice (Nice) in the city where he is located. The knot is a self-locking sliding knot, is similar to a strapping tape, can be gradually tightened, not only has higher fixing strength than other knots, but also can effectively reduce the loosening rate of the knot after operation. From the current literature reports, the Nice knot can be used for repairing soft tissues (tendon, ligament and skin soft tissues) and also can be used for bundling broken bone blocks of diaphysis fracture.
To finish the binding of the broken bone blocks of the diaphysis fracture, firstly, a double-strand ligature is required to penetrate through the broken bone blocks to be bound and the main bone stem; two common methods are available, one is to separate the soft tissue connecting the broken bone block and the main diaphysis by using vascular forceps and to pull the double-stranded ligature from one side to the other side by using the vascular forceps; the other is the so-called "threading technique" in which a single-thread needle is used to thread the bone pieces and main shaft from one side to the other, and then a double-stranded ligature is tied at the thread tail, and then a single-thread suture is pulled to pull the double-stranded ligature from one side to the other. The former has great damage to the blood supply of the broken bone blocks and influences the healing of the fracture; the latter procedure is relatively complicated and correspondingly increases the operation time.
In order to solve the above problems, the chinese patent literature: CN210204810U, announcement date: 2020.03.31, discloses a bifilar surgical suture needle, which comprises a bifilar phoenix tail thread and a surgical suture needle; the double-strand phoenix tail consists of three double-strand absorbable sutures and a joint part; a circle of semicircular clamping groove is formed in the side face of the combining part, and three double-strand absorbable sutures are fixedly connected to the left end of the combining part; the surgical sewing needle is integrally crescent-shaped, and a tail connecting hole is formed in the tail of the surgical sewing needle; a circle of semicircular bulge is arranged on the inner wall of the tail wire connecting hole; the combination part is inserted into the tail thread connection hole, the semicircular clamping groove is combined with the semicircular bulge, and the double-strand phoenix tail thread is connected with the surgical suture needle. The utility model discloses a patent has solved the double-strand ligature area line problem, but the structure is complicated, and needs special double-strand ligature, and manufacturing cost is high, and basic unit hospital uses the difficulty.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a Nice ligature leading-in needle, the effectual leading-in needle structure of current ligature of having solved is complicated, problem that manufacturing cost is high.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a Nice ligature leading-in needle comprises a leading-in needle body in a crescent structure, wherein the tail part of the leading-in needle body is connected with a ligature connecting block; the ligature connecting block is provided with a ligature connecting hole, and the ligature connecting block is also provided with a ligature sliding groove communicated with the ligature connecting hole.
Furthermore, a near-end groove edge and a far-end groove edge which are matched with the ligature sliding-in groove are arranged on the ligature connecting block, and the near-end groove edge and the far-end groove edge are both obliquely arranged.
Furthermore, one end of the ligature connecting block, which is far away from the needle body of the lead-in needle, is connected with an arc-shaped part.
Furthermore, wire grooves are formed in the ligature connecting block and the arc-shaped portion.
Furthermore, a needle holder clamping part is arranged at the end part of the leading-in needle body close to the ligature connecting block.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure, low in production cost, and easy operation, it is little to the soft tissue damage, the ligature that the operating room used at ordinary times all can use, is applicable to the garrulous bone piece that needs the Nice knot to tie up and other needs the Nice knot sutural soft tissue department, has practiced thrift operating time, has improved operation efficiency.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged schematic view of the region a in fig. 1 according to the present invention;
in the figure: 1. the ligature guide needle comprises a guide needle body 2, a ligature connecting block 3, an arc-shaped part 4, a wire groove 5, a ligature connecting hole 6, a near-end groove edge 7 and a far-end groove edge.
Detailed Description
A Nice ligature leading-in needle comprises a leading-in needle body 1 in a crescent structure, wherein the leading-in needle body 1 is designed into a round needle and a triangular needle, and the tail part of the leading-in needle body 1 is connected with a ligature connecting block 2; the ligature connecting block 2 is provided with a ligature connecting hole 5, the ligature connecting block 2 is also provided with a ligature sliding groove communicated with the ligature connecting hole 5, and the ligature sliding groove is arranged at the end part of the ligature connecting block 2 close to the leading-in needle body 1; the double-strand ligature is inserted into the ligature connecting hole 5 through the ligature sliding groove, and the double-strand ligature is guided in through the guide-in needle body 1 and the ligature connecting block 2.
Further, as shown in fig. 2, the ligature connecting block 2 is provided with a proximal groove edge 6 and a distal groove edge 7 which are matched with the ligature sliding-in groove, and both the proximal groove edge 6 and the distal groove edge 7 are obliquely arranged.
