Referring to fig. 1, fig. 1 is a simplified structural diagram of a disposable tissue piercing and suspending fastener according to an embodiment of the present disclosure.

In practice, the disposable tissue puncture suspension fixator is used in combination with a puncture needle or an introducer needle of a metal structure (usually, a steel structure), the puncture needle is usually a tubular structure with a tip and can puncture human tissues, the fixator extends into the punctured human tissues from the tubular structure of the puncture needle, the target tissues are fixed by opening the banding belts, the puncture needle can be drawn out of the target tissues, the fixator is fixed by locking devices such as clamps and the like positioned outside the human tissues, and the target tissues are fixed at a target position based on the fixator, so that a surgical operator can conveniently perform relevant surgical operations on a target object.

According to fig. 1, the utility model provides a disposable tissue piercing suspends fixer in midair can include tail end 1, near-end 2 and extend to the vertical main part 3 of near-end 2 from tail end 1, tail end 1 includes and is tail end strip 11 of predetermineeing the scope contained angle and is used for connecting tail end strip 11 and the connecting portion 12 of vertical main part 3 with vertical main part 3, near-end 2 is the bending of predetermineeing the angle scope for vertical main part 3, it has reducing structure 31 to distribute on the vertical main part 3.

The disposable tissue puncture suspension fixator has the advantages that by adopting the diameter-variable structure, under the condition that the tissue of a patient is not additionally damaged and is ensured to smoothly enter and be drawn out of the tissue of a human body, the friction force between the tissue and the palm of an operating doctor can be effectively enhanced, and the suspension failure caused by the slippage of the hand in the operating process is prevented; meanwhile, the locking clamp can be more effectively fixed on the longitudinal main body through the reducing structure, the phenomenon that the suspension effect is affected due to the fact that the longitudinal main body slides after suspension is prevented, and the smooth probability of operation progress is improved.

Preferably, after many experiments, the inventor preferably selects a regular-changing, alternating-thickness and gourd-shaped reducing structure at multiple positions after removing the results of unstable suspension, easy breakage of a suspension fixer, or easy accidental injury of a target suspension tissue caused by a dentate reducing structure with relatively poor suspension effect, a variable irregular reducing structure, and the like. More preferably, the diameter of the diameter-variable structure 31 of the present application is controlled within a range of less than or equal to 4 mm in terms of excellent suspension effect, fixing effect (avoiding breakage of the suspension fixture), and the like.

Preferably, in order to facilitate easier gripping of the single-use tissue-piercing suspension fixation device of the present application by an operator during a surgical procedure, the predetermined angular range of the proximal end 2 relative to the longitudinal body 3 is less than or equal to 90 degrees, taking into account the operator's handling habits, i.e. the structure of the proximal end 2 comprises a circular arc-shaped structure.

Preferably, in order to minimize the damage to the target tissue by the disposable tissue-piercing suspension fixator of the present application, the other parts of the disposable tissue-piercing suspension fixator except the diameter-variable structure 31, the tail end strip 11 and the connecting part 12 maintain the same outer diameter, and the maximum outer diameter of the diameter-variable structure 31 is smaller than or equal to the same outer diameter.

Preferably, in order to achieve the suspended fixation of the target tissue by the structure similar to the "T" structure or the umbrella-like structure, the caudal bar 11 of the present application includes a first portion 111 and a second portion 112, the thickness of the first portion 111 is the same as that of the connection portion 12, the thickness of the second portion 112 is 2 times that of the first portion 111, and the outer diameter of the second portion 112 is equal to the same outer diameter.

Preferably, in order to avoid the breakage of the tail end strip 11 during the process of suspending the tissue and to improve the tension or bearing force of the whole suspension fixator, the range of the diameter-variable structure 31 of the connecting part 12 closest to the connecting part includes 2-5cm. That is, the diameter-variable structure 31 of the connecting portion 12 closest to the connecting portion may be 2cm, 5cm, or a distance therebetween. Preferably, the thickness or outer diameter of the extension from the nearest reducing structure 31 to the connecting portion 12 is kept constant to further improve the traction during suspension.

Preferably, the angle formed by the first portion 111 and the connecting portion 12 includes 0 to 90 degrees. Preferably, the first portion 111 is at 90 degrees to the connecting portion 12 without constraint, so that the first portion 111 has an excellent rebound angle, the first portion 111 can be effectively prevented from puncturing the target tissue, and a better effect of suspending the tissue can be achieved. Preferably, to further achieve the safety of the surgical operation and avoid unnecessary damage to the target tissue by the single-use tissue-piercing suspension fixture, the angle formed by the second portion and the connecting portion ranges from 180 degrees to 90 degrees. More preferably, the second portion 112 is at 90 degrees to the connecting portion 12 without constraint.

Preferably, all portions of the single-use tissue-piercing suspension anchor are made of poly (methyl acrylate) or poly (methyl methacrylate), although other surgical grade materials known in the art to be suitable for use in the present application may be used. In contrast, the inventor adopts polymethyl acrylate or polymethyl methacrylate, and can realize better toughness and tensile property effects. Further preferably, the disposable tissue piercing and suspending fixture is integrally of unitary construction. Therefore, the tensile strength of the product is further improved by matching improved materials on the basis of the integrated structure, the deformation amount of the disposable tissue puncture suspension fixator during the tensile yielding is reduced, and the safety of the operation is improved.
