Abstract

The utility model relates to visualized spring grasping forceps, which are used for grabbing longitudinal traction drifting of mini-organs inside human bodies and belong to the field of medical apparatuses. The visualized spring grabbing forceps comprise a forceps rod, a pull rod, a connecting seat and a forceps block. The pull rod is sleeved inside the forceps rod, the tail of the pull rod penetrates through the forceps block and the connecting seat, and the forceps block is respectively and fixedly connected with the forceps rod and the connecting seat. The forceps are characterized by further including a forceps clamp, a spring sheet, a spring handle and a pull rod seat. One end of the spring sheet is fixedly connected with the forceps clamp while the other end is fixedly connected with the head of the pull rod; one end of the U-shaped spring handle is sleeved onto the connected seat while the other end is fixedly connected with the pull rod seat; and the pull rod seat is rotationally connected with the tail of the pull rod. When the visualized spring grabbing forceps are used in a grabbing longitudinal traction drift surgery on peripheral mini-organs of a focus portion, the forceps clamp has fine mini-organ grapping effect without injuring the mini-organs, and is small in shape and flexible in application.

Description

Direct-view spring nipper

Technical field

This utility model relates to a kind of direct-view spring nipper, and it is free to be used for that the inside of human body miniorgan is grasped longitudinal traction, belongs to medical instruments field.

Background technology

In human body direct-view laparoscopic surgery, it is free to grasp longitudinal traction to the miniorgan of lesions position periphery, prior art is with common nipper, the miniorgan who carries out people's internal lesions position periphery grasps longitudinal traction and dissociates, its defective is: the common sharp bodily form of hoe scaler pliers head clip tooth is big, can damage the miniorgan in the operation traction with in dissociating, cause the secondary wound, not satisfy ideal surgical effect.

The utility model content

The technical problems to be solved in the utility model overcomes above shortcomings in the existing structure exactly, and provides a kind of reasonable in design, operation to use convenient, effective, safe direct-view spring nipper.

The technical scheme in the invention for solving the above technical problem is: a kind of direct-view spring nipper comprises claw beam, pull bar, Connection Block and pincers seat; Drag link sleeve is contained in the claw beam, and its afterbody passes pincers seat and Connection Block; The pincers seat is fixedlyed connected with Connection Block with claw beam respectively; It is characterized in that: also comprise clamp, shell fragment, spring handle and draw-bar seat; Described shell fragment one end is fixedlyed connected with clamp, and the other end is fixedlyed connected with the head of pull bar; Described spring handle takes the shape of the letter U, and the one end is sleeved on the Connection Block, and the other end is fixedlyed connected with draw-bar seat; The afterbody of described draw-bar seat and pull bar is rotationally connected.

Spring handle described in the utility model is made with spring steel.

This utility model compared with prior art has following advantage and effect: 1, reasonable in design; 2, grasp in the free operation of longitudinal traction lesions position periphery miniorgan, it is effective that clamp grasps the miniorgan, can never damage the miniorgan, and the clamp bodily form is little, applying flexible.

Description of drawings

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

Fig. 2 is the structural representation of clamp part, and clamp is in open mode among the figure.

The specific embodiment

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

Embodiment:

This utility model embodiment comprises spring handle 1, pincers seat 2, claw beam 3, pull bar 4, draw-bar seat 5, pull rod slot 6, clamp 7, shell fragment 8, noinvasive flute profile 9, Connection Block 10, screw 11.

Spring handle 1 takes the shape of the letter U.Connection Block 10 is inserted in an end of spring handle 1, and spring handle 1 other end and draw-bar seat 5 welding are fixing.Draw-bar seat 5 has pull rod slot 6.Two shell fragments 8 have elasticity, and the one end is weldingly fixed on the

pull bar

4, and 7 welding of the other end and clamp fixedly make clamp 7 open naturally to have elasticity.Two clamps 7 have noinvasive flute profile 9, coincide mutually when noinvasive flute profile 9 clamps.Pincers seat 2 is fixing with claw beam 3 welding.Pull bar 4 penetrates claw beam 3, passes pincers seat 2 and Connection Block 10, is inserted in pull rod slot 6 usefulness screws 11 and is rotationally connected.

Direct-view described in the utility model is meant in operation process without pneumoperitoneum, undergos surgery under direct-view, certain space need not arranged in the human body body.

Spring handle 1 is that spring steel is made, and itself has elasticity, drives 7 work of rubber-like clamp, clamps firmly can arbitrarily not come off, and simplicity of design is reasonable, applying flexible, safety easy to use.

The art designs of clamp 7 has or not the gear-shaping type, grasps in the free operation of longitudinal traction lesions position periphery miniorgan, and it is effective that the noinvasive flute profile of clamp 7 grasps the miniorgan, can never damage the miniorgan, and clamp 7 bodily forms is little, applying flexible.

This utility model removes and installs conveniently, and closure is good, and metal material is made, and sterilization can be used liquid disinfectant, also can use high-temperature sterilization.

Claims
