DETAILED DESCRIPTION OF THE INVENTION

Before the present disclosure is described in detail, it should be noted that similar components in the following description will be indicated in a same numeral.

Referring toFIG.1, a first embodiment of the micro needle holder capable of cutting sutures of the present disclosure is configured for holding needles and cutting sutures during microsurgeries, the micro needle holder capable of cutting sutures100comprises a needle holding unit1and a suture cutting unit2.

The needle holding unit1comprises a pair of first plier bodies11and a first shaft12, where each of the first plier bodies11has a needle holding end111, a first shaft connecting part112in connection with the needle holding end111, and a first plier arm113in connection with the first shaft connecting part112, the pair of the first plier bodies11are over-stacked via the first shaft connecting parts112and in an intersecting configuration, the first shaft12is pivoted at the first shaft connecting parts112, so that the first shaft connecting parts112may be rotatably connected relative to each other, the needle holding ends111may be opened and closed relative to each other, and the first plier arms113may be opened and closed relative to each other.

The suture cutting unit2comprises a pair of second plier bodies21and a second shaft22, where each of the second plier bodies21has a suture cutting end211, a second shaft connecting part212in connection with the suture cutting end211, and a second plier arm213in connection with the second shaft connecting part212, the pair of the second plier bodies21are over-stacked via the second shaft connecting parts212and in an intersecting configuration, the second shaft22is pivoted at the second shaft connecting parts212, so that the second shaft connecting parts212may be rotatably connected relative to each other, the suture cutting ends211may be opened and closed relative to each other, and the second plier arms213may be opened and closed relative to each other.

In some embodiments, the first plier arms113are respectively connected with the second plier arms213and may be elastically opened and closed corporately. In this first embodiment, distal ends of the first plier arms113are pivoted on distal ends of the second plier arms213respectively, and the suture cutting unit2further comprises an elastic member23provided between the second plier arms213, so that the first plier arms113and the second plier arms213can be elastically opened and closed. In a varied embodiment, the needle holding unit1may further comprises an elastic member23provided between the first plier arms113, so that the first plier arms113and the second plier arms213can be elastically opened and closed; alternatively, the needle holding unit1and the suture cutting unit2may each comprises an elastic member23provided between the first plier arms113and between the second plier arms213, respectively.

The elastic member23keeps the first plier arms113and the second plier arms213relatively open during an unemployed state, and keeps the needle holding ends111and the suture cutting ends211relatively open at the same time. When a user applies force on the first plier arms113or the second plier arms213to make the first plier arms113and the second plier arms213approach each other, the needle holding ends111are made to abut against each other to hold the needle, and the suture cutting ends211are made to abut against each other to cut off the suture. When the user removes the force, the first plier arms113and the second plier arms213are restored to the relatively open state by the elastic member23. Since the diameters of the needles and sutures used in general microsurgeries are about 0.02 to 0.04 mm, the sizes of the needle holding ends111and the suture cutting ends211are rather small, and the needle holding ends111and the suture cutting ends211are kept open by elastic force, which can facilitate the operation. Preferably, an opening angle held for the needle holding ends111and the suture cutting ends211is between 5 to 30 degrees. In this embodiment, the first plier bodies11and the second plier bodies21are made of stainless steel, which can withstand high temperature sterilization and collision, and other suitable materials can also be selected from titanium alloy, tantalum alloy, copper alloy, aluminum alloy, magnesium alloy, nickel alloy, or silicone rubber, etc.

During holding of a needle, the user may hold the first plier bodies113in hand and apply force thereto, so as to hold the needle by the needle holding ends111. During cutting of a suture, the user merely needs to switch direction of the needle holding unit1and the suture cutting unit2, making the suture cutting ends211facing the suture, hold the second plier bodies213in hand and apply force thereto, so as to cut the suture by the suture cutting ends211. As such, the user may single-handily operate and switch direction of the needle holding unit1and the suture cutting unit2without help from others, and the cutting of the suture may be operated by the suture cutting unit2upon completion of the stitching process. Accordingly, the stitching movement and suture cutting movement may be accomplished in one iteration, the inconvenience during procedure of microsurgeries may be reduced, and any possible mishaps while waiting for exchange of tools may be avoided.

Referring toFIG.2, a second embodiment of the micro needle holder capable of cutting sutures of the present disclosure is substantially the same as the first embodiment, and differences lies in that, in the second embodiment, each of the first plier arms113and the second plier arms213comprises an elastic section113aand an elastic section213a, respectively, at the distal ends thereof, and the elastic sections113aof the first plier arms113are respectively connected with the elastic sections213aof the second plier arms213, hence provide similar function described in the first embodiment as distal ends of the first plier arms113and the second plier arms213being pivoted together, and enable connection and corporate opening and closing between the first plier arms113and the second plier arms213.

Referring toFIG.3, a third embodiment of the micro needle holder capable of cutting sutures of the present disclosure is substantially the same as the second embodiment, and differences lies in that, in the third embodiment, the needle holding ends111have a curved shape bent in a direction from one end connected to the first shaft connecting parts112toward a distal end, and the suture cutting ends211have a curved shape bent in a direction from one end connected to the second shaft connecting parts212toward a distal end, where the bending is less obvious toward the distal ends. With the curved shapes of the needle holding ends111and the suture cutting ends211, application of force during operation may become more convenient, and the curved shapes of the suture cutting ends211may further prevent sutures being cut off falling into bodies of recipients of surgeries.

In conclusion, the needle holding ends111and the suture cutting ends211disposed on opposite sides may enable the user to operate single-handily to select the needle holding ends111for holding the needle or select the suture cutting ends211for cutting off the suture, the stitching movement and suture cutting movement may be accomplished in one iteration, the inconvenience during procedure of microsurgeries may be reduced, and any possible mishaps while waiting for exchange of tools may be avoided.

However, the descriptions above are merely embodiments of the present disclosure and should not be construed as limitations to the scope of the present disclosure. All simple equivalent variations and modifications according to appended claims and the present disclosure should fall within the scope of the appended claims.
