In addition, under the relaxed state, the threading needle can roll back in hollow tube, is a protection mode, effectively avoids stabbing human tissue, has improved the security in the threading process.
As shown in fig. 2 and 3, the clamping portion comprises an inner jaw 9 and an outer jaw 8, and soft tissue is clamped and fixed by the cooperation of the inner jaw 9 and the outer jaw 8. The inner and outer jaws may be clamped by fixing one jaw and closing the other jaw (including fixing the inner jaw and moving the outer jaw or fixing the outer jaw and moving the inner jaw), or by moving both jaws.
The embodiment adopts the clamping mode of outer jaw fixing and inner jaw action: the outer jaw is fixed at the upwarping front end of the extension part and is in a flat hook shape extending downwards, so that the lower edge of a threading end of soft tissue sewed into the incision is convenient to cut; the inner jaw is hinged to the upwarping front end of the extending part and is in a herringbone structure with the outer jaw in an opening state.
Furthermore, the outer side of the inner jaw 9 and the inner side of the outer jaw 8 are both provided with anti-slip tooth-shaped structures 10, so that soft tissue clamping is more stable.
Furthermore, a waist hole 14 for the threading needle 6 to pass through is arranged on the inner jaw 9, so that the threading needle can conveniently pass through the jaws in an opening state and a closing state.
Furthermore, a U-shaped wire binding groove 11 for hanging wires is arranged on the inner side of the outer jaw 8, and a needle threading hole 13 for the threading needle 6 to penetrate through is arranged in the U-shaped wire binding groove 11. The design of U type wiring groove can let the string location of keeping silent outward more stable, makes things convenient for the threading needle to pierce through the soft tissue after, and the accurate suture of colluding back rapidly.
In addition, the outside of hanging wire portion is equipped with wide groove 12, both has been close U type groove, makes things convenient for interim encircleing and fixing of operation central line, can provide the space again for avoid interim wire winding knot to the hanging wire portion to scratch into the soft tissue dorsal part and cause and block.
Fig. 6 shows a structural form of the clamping mechanism: the clamping mechanism comprises a first connecting rod 19 and a second connecting rod 20 which are connected between the transmission rod 5 and the inner jaw 9 and are hinged with each other to form a crank block mechanism, and the inner jaw 9 is driven to rotate by pushing and pulling the transmission rod 5, so that the clamping part is closed and opened. In other embodiments, other plane clamping mechanisms can be adopted to realize the transmission control of the transmission rod and the inner jaw, so that the synchronous control of the threading needle and the clamping part by the near-end finger ring is realized, and the difficulty in the suture and threading of the facet joint is greatly reduced.
Furthermore, a torsion piece is arranged on the extension part 4, and the torsion piece drives the extension part to be positioned in a torsion mode relative to the handle part, so that the operation angles of the extension part and the clamping part can be adjusted.
In this embodiment, the twist reverse piece adopts cup joint the wrench nut 15 on extension 4, can drive the integral type of extension through wrench nut and rotate around the casing, and rotation range can fixed use after rotating within 360 degrees, rotates the in-process and sews up structures such as keeping silent and threading needle and follow-up, cooperates the sewing up of different angles, conveniently sews up the operation.
As shown in fig. 4, the periphery of the twist nut 15 is provided with anti-slip teeth to increase friction force and facilitate operation in surgery, the twist nut 15 is provided with a wire clamping groove 21, and the wire clamping groove 21 is of a structure with a wide upper part and a narrow lower part, so that the suture line can be conveniently slid in and temporarily clamped.
The specific embodiment of the invention is as follows:
during threading, firstly, a suture is wound in the U-shaped bunching groove 11 of the outer jaw 8, then the outer jaw 8 is hooked at the inner side of a soft tissue (such as a tendon and a ligament) to be sewn, the inner jaw 9 is arranged at the outer side of the soft tissue, then the near-end finger ring 3 is pressed down to drive the inner jaw 9 to be closed to clamp the soft tissue, meanwhile, the threading needle 6 is driven to be pushed out, the suture passes through the waist hole 14 on the inner jaw 9 and the soft tissue and enters the threading needle hole 13 of the U-shaped bunching groove 11, the suture in the U-shaped bunching groove 11 is hooked in the bunching groove 7, finally, the near-end finger ring 3 is loosened (or actively pulled back), the threading needle 6 is driven to retreat, the suture is pulled from the opposite side of the soft tissue (the tape passes through the soft tissue), and meanwhile, the inner jaw 9 is opened (the clamping is loosened), and the threading process is realized.
In a free state, the near-end ring 3 is supported out under the action of the spring, and the threading needle 6 is retracted in the tube to prevent the sharp needle head from stabbing human tissues. Therefore, besides the auxiliary threading operation, the threading device can assist various operations (such as clamping soft tissues, temporary winding and the like) in the operation, and the operation is very convenient.
The invention has the advantages of exquisite and smooth integral structure, convenient use, lower cost, smaller incision due to the vertical slender extension structure and easier operation of sewing. During threading, the outer jaw is only required to be placed in the inner side of soft tissue (such as tendon and ligament), the inner jaw is placed in the outer side of the soft tissue to clamp the soft tissue, then the soft tissue can be punctured through pushing and pulling back the needle to hook the suture, synchronous operation of soft tissue clamping and suture threading is convenient to carry out, the surgical threading operation with small space is very suitable, and the surgical threading difficulty is greatly reduced.
The above detailed description merely describes preferred embodiments of the present invention and does not limit the scope of the invention. Without departing from the spirit and scope of the present invention, it should be understood that various changes, substitutions and alterations can be made herein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
