Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are to be construed broadly, e.g., "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the embodiment, as shown in fig. 1 to 3, the surgical hemostat comprises two forceps arms 1 which are arranged in a crossing way, wherein the middle front parts of the two forceps arms 1 are hinged, the front end parts of the forceps arms 1 are fixedly provided with forceps heads 2, the middle rear parts of the two forceps arms 1 are provided with toothed plates 3 which are oppositely arranged, the rear end of the forceps arm 1 is detachably provided with a handle annular ring which comprises a finger ring 4 and an inserting rod 5, the finger ring 4 is fixed on the outer side of one end of the inserted bar 5, the outer side of the other end of the inserted bar 5 is provided with a first locking tooth 6, the outer side of the middle rear part of the forceps arm 1 is provided with an insert ring 7, the outer side of the middle part of the forceps arm 1 is also provided with a locking plate 8, one end of the locking plate 8 is hinged to the forceps arm 1, a second locking tooth 9 is arranged on the inner side of the other end of the locking plate 8, and elastic clamping pieces 10 are further arranged on the upper end and the lower end of the locking plate 8 inwards.

In this embodiment, the outer side of the rear portion of the jawarms 1 is further provided with a slot 11, the inner side of the insertion rod 5 is provided with a convex strip 12, and the convex strip 12 slides in the slot 11.

The working principle of the technical scheme is as follows:

during the use, press from both sides tight hemostasis position when hemostatic forceps to through the pinion rack 3 locking back, open lockplate 8 and make first locking tooth 6 and the separation of second locking tooth 9, then pulling handle annular ring makes inserted bar 5 extract from inserting in the ring 7, realizes the separation. When it is desired to release the hemostat, the rod 5 of the handle ring is inserted into the ring 7, and the locking plate 8 is then depressed so that the first locking tooth 6 and the second locking tooth 9 engage and the resilient tab 10 clamps the jawarm 1 to secure it.

Compared with the prior art, the utility model has the advantages that:

firstly, this embodiment can make the annular circle of handle and tong arm separation by hand after fixing hemostatic forceps, avoids the handle to influence doctor's operating space and sight, has improved operation efficiency.

Second, the setting of locking plate in this embodiment for handle annular ring realizes locking with the tong arm, avoids the pine to take off.

And thirdly, due to the arrangement of the elastic clamping piece, the clamp arm and the locking plate are locked, and the loosening is avoided.

Fourth, the setting of this embodiment slot and sand grip for when combining handle annular ring with the tong arm, the restriction angle makes first locking tooth and the smooth meshing of second locking tooth.

The above are merely preferred embodiments of the present invention; the scope of the utility model is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
