Background technology

In the peritoneoscope human abdominal cavity, in the operation, need cut off or excise pathological tissues in the human abdominal cavity.Prior art is to adopt general straight scissors cutter and scalpel that pathological tissues is cut off or excises, its defective is that the straight scissors cutter is when cutting off or excise, because be in human abdominal cavity, in the operation that undergos surgery of laparoscopically video, the straight scissors cutter is easy to slippage in operation technique, the operation trouble does not satisfy ideal surgical effect.

The utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides the hook of a kind of reasonable in design, good operation effect to cut.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of hook is cut, and it is characterized in that: comprise fixed handle, flexible handle, runner, rotaring wheeling sleeve, ball cover, adapter sleeve, claw beam, shears seat, shears, pull bar; Fixed handle and flexible handle are rotationally connected; The runner suit is fixed on the rotaring wheeling sleeve; Adapter sleeve is fixedlyed connected with the ball cover with fixed handle respectively; The ball cover is sleeved on the rotaring wheeling sleeve; Claw beam one end and rotaring wheeling sleeve are fixed, and the other end and shears seat are fixed; Shears comprises movable scissors and fixed blade, and movable scissors and fixed blade cooperate; Pull bar one end and flexible handle are rotationally connected, and the other end and movable scissors are rotationally connected; Fixed blade is fixed on the shears seat, and movable scissors also is rotationally connected with the shears seat; The cutting edge of movable scissors and fixed blade is arc.

Have electricity on the fixed handle described in the utility model and coagulate installing hole.

On the flexible handle described in the utility model limit base is installed.

This utility model compared with prior art has following advantage and effect: 1, reasonable in design; 2, in cut-out or removal lesion tissue's operation, convenient, effective, safety is used in operation.

Description of drawings

Fig. 1 is the structural representation of this utility model embodiment.

Fig. 2 is this utility model embodiment partial structurtes sketch maps.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.

Embodiment: referring to Fig. 1 and Fig. 2, fixed handle 1 and flexible handle 2 are rotationally connected.

Limit base 3 is installed on the flexible handle 2, is used for the rotational angle of restraint handle 2, and pulling shears binder tool can arbitrarily not damage.Electricity coagulates installing hole 5 to be opened on fixed handle 1, electricity can be installed in the hole coagulate socket, reaches hook and cuts the effect that electricity coagulates.

Runner 14 suits are fixed on the rotaring wheeling sleeve 8.Adapter sleeve 13 overlaps 4 with fixed handle 1 and ball respectively fixedlys connected.Ball cover 4 is sleeved on the rotaring wheeling sleeve 8, between ball cover 4 and rotaring wheeling sleeve 8 bearing is installed.Flushing hole 15 is fixed on the runner 14, can wash the residual liquid sterilization with disinfectant solution, also can use high-temperature sterilization.Flushing port lid 6 is installed in the flushing hole 15.

Claw beam 7 one ends and rotaring wheeling sleeve 8 are fixing, and the other end and shears seat 16 are fixing.Shears 9 is rotatably connected on the shears seat 16.Pull bar 11 1 ends pass adapter sleeve 13, runner 14, fixed handle 1 back and flexible handle 2 and are rotationally connected, and the other end and movable scissors 10 are rotationally connected.

Open in the abdomen operation process in that human body intracorporeal organ tissue cut is grasped localized direct-view, runner 14 can drive shears 9 and do 360 degree rotations, improves its effect, reaches the multifunctionality of application.

Shears 9 comprises movable scissors 10 and fixed blade 12, and movable scissors 10 and fixed blade 12 cooperate.Fixed blade 12 is fixed on the shears seat 16, and movable scissors 10 is rotationally connected with pull bar 11 and shears seat 16 respectively.The cutting edge 17 of movable scissors 10 and the cutting edge 18 of fixed blade 12 are arc, make shears 9 partly be hook-shaped at cutting edge.In the operation, in cut-out or removal lesion tissue, the shears 9 of curved cutting edge is in excision in direct-view peritoneoscope human abdominal cavity, and point of a knife is introduced into truncation surface, and back removal lesion tissue can slippage.

As long as hold handle with a firm grip, flexible handle 2 pulling pull bars 11, pull bar 11 pulling movable scissors 10, shears 9 closures; Opening handle shears 9 opens.
