Abstract

The utility model relates to a forward-viewing minimal invasive O-shaped grasping forceps, which is mainly applied to traction and dissociation of tubular organs on the peripheries of focuses in abdominal cavities of human bodies. The forward-viewing minimal invasive O-shaped grasping forceps comprises a fixed handle, a movable handle, a rod, a clamp holder, a draw rod, a rotary wheel, a rotary wheel sleeve, an idler wheel, an idler wheel sleeve, a connecting sleeve, a draw rod sleeve, a fixed sleeve, a draw rod holder, a flushing hole cover, a clamp, a connecting plate and a draw rod connector. The forward-viewing minimal invasive O-shaped grasping forceps is characterized in that the clamp is an ellipse clamp, nondestructive teeth are arranged inside the ellipse clamp, a limit holder is further installed on the movable handle, and an electric coagulation installation hole is arranged on the fixed handle. The forward-viewing minimal invasive O-shaped grasping forceps has reasonable structural design, excellent traction and dissociation effects, convenient and safe surgery and small injury on organs of patients.

Description

The direct-view O of Wicresoft type nipper

Technical field

This utility model relates to a kind of nipper, the particularly a kind of direct-view O of Wicresoft type nipper, and it mainly is applicable to draws and dissociates the pipe of human abdominal cavity inner disease foci periphery, belongs to technical field of medical instruments.

Background technology

In direct-view Wicresoft peritoneoscope human abdominal cavity in the operation, need draw and dissociate the pipe of human abdominal cavity inner disease foci position periphery, so that operative site has the operation that undergos surgery of enough spaces.Prior art is to adopt common hoe scaler that the pipe of lesions position periphery is drawn and dissociate, and because of hoe scaler has special-purpose ellipse clamp design, also harmless flute profile designs, and very easily causes the damage of organ pipe.

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, and can arbitrarily not damage the O of the direct-view Wicresoft type nipper of organ.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: this O of direct-view Wicresoft type 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, flushing port lid, clamp, connecting plate and pitman coupling, it is characterized in that: described clamp is the ellipse clamp, is provided with the harmless tooth of bending in the inboard of this ellipse clamp; Also be provided with limit base, described limit base is installed on the flexible handle, and has electricity installing hole with fixed attention on fixed handle.

This utility model compared with prior art has following positive effect: reasonable in design, and design has ellipse clamp and harmless flute profile, can carry out the traction of pipe and free effectively, and traction and free effective, facilitating operation safety is little to patient's organ injury.

Description of drawings

Fig. 1 is a structural representation front view of the present utility model.

Fig. 2 overlooks enlarged drawing for the structural representation at A place among Fig. 1.

Structural representation when Fig. 3 opens for ellipse clamp among Fig. 2.

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, flushing port lid 18, ellipse clamp 19, connecting plate 22 and pitman coupling 15.

Fixed handle 1 of the present utility model 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 opens on fixed handle 1.

Claw beam 4 is fixing with runner 7 welding, and 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 runner 7 and rotaring wheeling sleeve 8 are passed in flushing hole 17, and rotaring wheeling sleeve 8 is fixing in runner 7 welding, and flushing port lid 18 inserts flushing hole 17 and connects.

The inboard of two ellipse clamps 19 is provided with the harmless tooth 24 of bending, and harmless tooth 24 coincide mutually when clamping, and the other end crosses one another, and is connected on the clamp seat 5 with clipper joint pin 20 at infall, can rotate; The bottom of two ellipse 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 other end of pitman coupling 25 is fixing in the end welding of pull bar 6, 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, pull bar 9 pulling ellipse clamps 19, binding clip closure; Open handle, binding clip opens.

Clamp of the present utility model is ellipse and flexibly movable, and be provided with harmless tooth 24, in the peritoneoscope human body operation of direct-view Wicresoft, be disciform clamp clamping organ and have certain space, the flute profile of harmless tooth 24 is rounded, clamps and can arbitrarily not damage organ.

Runner 7 described in the utility model, in operation was used, clamp can 360 ° of rotations, and what be convenient to perform the operation carries out smoothly, reaches its multifunctionality.

This utility model is equipped with limit base 16 on flexible handle 2, electricity is installed on fixed handle 1 coagulates installing hole 26, and being installed in the operation application of limit base 16 spurs the clamp apparatus and can arbitrarily not damage; Electricity coagulates the installation of installing hole 26, electricity can be installed in the hole coagulate socket, reaches the effect that O type nipper electricity coagulates.

This utility model can irrigation and disinfection, also can use high-temperature sterilization.

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.
