Abstract

The utility model provides a two-point retractor which comprises a shell body, retractor arms and retractor hooks. The shell body is formed by welding two cannulas and a gear cavity, the inner cavities of the two cannulas are communicated with the gear cavity, a sliding bar is respectively arranged inside the two cannulas, one side of each sliding bar is provided with a tooth slot, the sliding bars are connected with the cannulas in a sliding way, a gear is arranged inside the gear cavity, the gear meshes with the corresponding tooth slot of the two sliding bars, a knob is fixedly connected on the axle center of the gear, the knob passes through the axle hole of the shell body to be connected with the shell body in a rolling way, the ends of the two sliding bars symmetrical with each other based on the axle center of the gear are respectively provided with a retractor arm, one end of each retractor arm is provided with a retractor hook; one side of the gear cavity is additionally provided with a tooth-clanging clasper, the tooth-clanging clasper is connected with a shaft arranged on the shell body through hinge connection, and the shaft is provided with a shaft-hinge spring. The two-point retractor utilizes the rotation of the gear to drive the two sliding bars to move in the opposite directions, and the retractor displacement is twice of the rotary linear velocity of the gear, thereby being more beneficial for improving the work efficiency and reducing the labor intensity of health-care operators.

Description

2 retractors

1, technical field

This utility model relates to a kind of technical field of medical instruments, and a kind of 2 retractors specifically are provided.

2, background technology

Retractor occupies considerable status in medical apparatus and instruments, especially playing the part of crucial role in operating theater instruments.General retractor great majority are to utilize the made tong-like of lever principle or other shapes realize retracting action, because in the lever principle, the requirement of comparison harshness is all arranged for the position of the length of the arm of force and fulcrum, in general the range of application of retractor is very broad and application is various, because retractor is directly to manufacture and design at applied object with regard to it mostly, the specific aim of the feasible like this retractor that produces is very strong, but its range of application is very much limited, for example direct qualitative its application of length of the openings of sizes of tong-like retractor and pincers handle also will carry out the initial option of apparatus to retractor when this makes the doctor at its operational objectives.Whether at present can provide a kind of retractor just almost can solve the wider apparatus of most problem and range of application, be that a technology contents to be solved is arranged.

3, summary of the invention

Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of use and retractor easy to operate and that range of application is wider are provided, and is a kind of 2 retractors specifically.

The technical solution of the utility model realizes in the following manner, 2 retractors, comprise housing, drawing arm and hook retractor, housing is made of two sleeve pipes and a gear cavity welding, two cannula cavity communicate with gear cavity, be respectively arranged with slide bar in two sleeve pipes, slide bar one side has teeth groove, slide bar and sleeve pipe are slidingly connected, be provided with a gear in the gear cavity, gear is meshed with the teeth groove of relative two slide bars simultaneously, is fixedly connected with knob on the axle center of gear, knob passes the housing axis hole and is connected with the housing rolling, two slide bars are respectively arranged with drawing arm with the symmetrical end of gear axis, and an end of drawing arm is provided with hook retractor, and gear cavity one side also is provided with clanging or clanking sound tooth button, clanging or clanking sound tooth button is hinged with the axle axle that is arranged on the housing, and axle is provided with axle hinge spring.

Two sleeve pipes parallel, and gear cavity is between two sleeve pipes.

Drawing arm and slide bar are perpendicular, and drawing arm is threaded with slide bar.

Two drawing arms are arranged on the same side of housing.

An end relative with the slide bar end that is provided with drawing arm on the slide bar is provided with spacing block set, and spacing block set is threaded with slide bar.

The utility model has the advantages that:

These 2 retractors use and easy to operate and range of application is wider, utilize the rotating drive two slide bar move toward one another of gear, and retracting displacement is the twice of gear rotational line speed, more helps increasing work efficiency reduction medical care operator's labor intensity.
