Portable operation-type suture needle holder conforming to small-incision and wide-angle in-depth operation

Abstract

The invention discloses a portable operation-type suture needle holder conforming to small-incision and wide-angle in-depth operation. The suture needle holder comprises an outer sleeve, a needle holder assembly, a telescopic sleeve, a front end cover nut, a spring, a jaw adjusting nut and a driving assembly; the needle holder assembly includes a long rod, a pair of semi-circular rods extending atthe front end of the long rod, and needle holder heads extending at front ends of the semi-circular rods respectively; a free gap is reserved between the two needle holder heads; a rod body thread section used for being in thread fit connection with the jaw adjusting nut is arranged at the rear end of the long rod in an extending manner; the telescopic sleeve is movably arranged on the long rod in a sleeving manner; and the front end of the telescopic sleeve is butted onto outer oblique walls of the needle holder heads, and a sliding sleeve extends at the rear end of the telescopic sleeve. The suture needle holder has a reasonable structural design, a compact structure and small space occupation, realizes suturing of deep tissue under the small incision condition, solves the technical problem that suturing cannot be realized by other surgical instruments at a surgical dead corner position, achieves the purposes of precise suturing and trauma reduction, and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of surgical tools, in particular to a portable suture needle holder suitable for small incisions, wide angles and deep operations. Background technique [0002] Since surgical operation, the suturing of various tissues including blood vessel and tissue etc. adopts needle holder to hold and take suture needle to operate always. Surgical techniques such as staplers have emerged in recent years. [0003] Currently, the needle holder used in surgery has a clamp structure. For the suture of deep tissues, especially the deep tissue suture under the current popular small incision surgery, it is easy for the needle holder to be blocked by superficial tissues, and the suture needle cannot be delivered. If the target area is reached, or cannot be operated flexibly in the target area, at the same time, due to the large volume of the needle holder, it will block the surgical light and the doctor's field of vision when ...

AI Technical Summary

Problems solved by technology

[0003] Currently, the needle holder used in surgery has a clamp structure. For the suture of deep tissues, especially the deep tissue suture under the current popular small incision surgery, it is easy for the needle holder to be blocked by superficial tissues, and the suture needle cannot be delivered. The target area is not reached, or the target area cannot be operated flexibly. At the same time, due to the large volume of the needle holder, it will block the surgical light and the doctor's field of vision when operating in the deep part of the incision.

The stapler can only be used for suturing under specific circumstances, which is not only expensive, but often requires residual implants, and it cannot be used in fields that require delicate operations, such as dural sac repair, etc.
