Description

Direct-view Wicresoft duckbilled nipper

Technical field

This utility model relates to a kind of nipper, particularly a kind of direct-view Wicresoft duckbilled nipper, and it is exclusively used in grasps when organ-tissue is bonded to each other in the human abdominal cavity and separates, and belongs to medical instruments field.

Background technology

In the operation of direct-view Wicresoft peritoneoscope human body, need grasp and separate organ-tissue in the human abdominal cavity is bonded to each other, so that operation is carried out smoothly.Prior art is to adopt common nipper to grasp and separate organ-tissue is bonded to each other, and Yin Putong nipper binding clip is rounded, and also harmless flute profile and release groove design are difficult to tissue bonded to each other is grasped and separates, and easily can cause the damage of tissue.

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 a kind of reasonable in design is provided, the direct-view Wicresoft duckbilled nipper of extracting and good separating effect.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: this direct-view Wicresoft duckbilled nipper comprises fixed handle, flexible handle, claw beam, clamp seat, pull bar, runner, rotaring wheeling sleeve, roller, ball cover, adapter sleeve, drag link sleeve, fixed cover, draw-bar seat, limit base, rinse piece, flushing port lid, clamp, connecting plate and pitman coupling, it is characterized in that: described clamp is the platypelloid type clamp, all have rectilinear harmless tooth in the inboard of each clamp, the centre of this one of them harmless tooth is provided with a rectangle bag and holds together groove.

This utility model compared with prior art has following positive effect: reasonable in design, by harmless tooth and release groove, can effectively adherent organ-tissue be grasped and separate, and extracting and good separating effect, it is easy to use to perform the operation, and safe and reliable.

The specific embodiment

Referring to Fig. 1-Fig. 3, this utility model mainly is made up of fixed handle 1, flexible handle 2, claw beam 4, clamp seat 5, pull bar 6, runner 7, rotaring wheeling sleeve 8, roller 9, ball cover 10, adapter sleeve 11, drag link sleeve 12, fixed cover 13, draw-bar seat 14, limit base 16, rinse piece 17, flushing port lid 18, clamp 19, connecting plate 22 and pitman coupling 25.

Fixed handle 1 is connected with flexible handle 2 usefulness hold-down screws 3, can rotate; Pull rod slot 15 is opened on flexible handle 2, and limit base 16 is installed on the flexible handle 2, and electricity coagulates installing hole 26 and is installed on the fixed handle 1.

Claw beam 4 is fixing with runner 7 welding.Rotaring wheeling sleeve 8 is equipped with two rollers 9, and fixed cover 13 is filled in the rotaring wheeling sleeve 8, and adapter sleeve 11 is installed in outside the rotaring wheeling sleeve 8, and ball cover 10 is installed in rotaring wheeling sleeve 8 and roller 9 and adapter sleeve 11 outer being fixed; Drag link sleeve 12 is filled in the adapter sleeve 11, and fixed handle 1 is installed in drag link sleeve 12 and adapter sleeve 11 outer being fixed; Rotaring wheeling sleeve 8 penetrates runner 7, and rinse piece 17 passes runner 7 and rotaring wheeling sleeve 8 and in runner 7 welding, flushing port lid 18 is connected and fixed with rinse piece 17.

The inboard that two flat clamps 19 have 27, two flat clamps 19 of release groove has harmless tooth 24, and harmless tooth 24 and release groove 27 coincide mutually when clamping, and the other end crosses one another, and is connected on the clamp seat 5 with clamp connecting pin 20 at infall, can rotate; The bottom of two flat clamps 19 is connected on two connecting plates 22 with connecting plate connecting pin 21, can rotate; Two connecting plate 22 usefulness link pins 23 are fixed on an end of pitman coupling 25, and the end welding of the other end of pitman coupling 25 and pull bar 6 is fixing, and the other end of pull bar 12 is provided with draw-bar seat 14.

Pull bar 6 penetrates claw beam 4, passes rotaring wheeling sleeve 8, drag link sleeve 12 and fixed cover 13, and it is identical fixing that draw-bar seat 14 is inserted in pull rod slot 15, and clamp seat 5 is weldingly fixed on the claw beam 4; As long as at this moment hold handle with a firm grip, flexible handle 2 pulling pull bars 6, the flat clamp 19 of pull bar 6 pullings, binding clip closure; Open handle, binding clip opens.

Harmless tooth 24 of the present utility model and release groove 27, in the peritoneoscope human body operation of direct-view Wicresoft, being flat clamp 19 is organizing bonded to each other the extracting can arbitrarily not damage tissue when separating, under the effect of harmless tooth 24, can arbitrarily not clip broken tissue during the grip tissue cell membrane, under the effect of release groove 27, make and organize the cell membrane clamping plane littler.

This utility model is equipped with limit base 16 on flexible handle 2, can arbitrarily not damage tissue during pulling clamp apparatus; 1 is equipped with electricity installing hole 26 with fixed attention on fixed handle, electricity can be installed in the hole coagulate socket, reaches the effect that electricity coagulates.

Direct-view described in the utility model Wicresoft is meant in the operation process to undergo surgery under direct-view without pneumoperitoneum certain space not to be arranged in the human body body.
