Abstract

The utility model discloses a novel cervical vertebra retractor, which comprises: the handle, the connecting rod and the hook body are integrally arranged at two ends of the handle, the hook bodies are arranged at the top ends of the two connecting rods, and the included angle between the hook body and the connecting rod is smaller than 90 degrees; in this application, the hook body is not perpendicular with the connecting rod setting, and when using, grab handle and hand's position is lower, can not shelter from operating doctor's sight to grab handle middle section is crooked, holds the mode of hook more nimble stable.

Description

Novel cervical vertebra drag hook

Technical Field

The utility model relates to the field of surgical instruments, in particular to a novel cervical vertebra retractor.

Background

When in cervical vertebra operation, the cervical vertebra retractor is required to be used, and tissues in front of the cervical vertebra are pulled out through the cervical vertebra retractor.

The existing cervical vertebra drag hook has the advantages that the hook body is perpendicular to the holding rod, when the existing cervical vertebra drag hook is used, the positions of the holding rod and the hands are higher, the vision of a surgeon can be shielded, and certain obstacle can be caused to the operation.

Disclosure of Invention

The utility model mainly solves the technical problems that: when the existing cervical vertebra drag hook is used, the positions of the holding rod and the hand are higher, and the vision of a doctor can be blocked.

In order to solve the technical problems, the utility model adopts a technical scheme that:

a novel cervical vertebra retractor, comprising: grab handle, connecting rod, coupler body, the both ends of grab handle are all provided with the connecting rod in an integrated way, two the top of connecting rod all is provided with the coupler body to the contained angle of coupler body and connecting rod is less than 90.

Further: the hook surface of the hook body is a convex curved surface.

Further: the tail end of the hook body is provided with a bent hook tip.

Further: the two hook bodies at two sides of the grab handle are different in size.

Further: two sections of anti-slip parts are arranged on the grab handle, and a bending part is arranged between the two sections of anti-slip parts.

The beneficial effects of the utility model are as follows:

in this application, the hook body is not perpendicular with the connecting rod setting, and when using, grab handle and hand's position is lower, can not shelter from operating doctor's sight to grab handle middle section is crooked, holds the mode of hook more nimble stable.

FIG. 2 is a schematic view of the structure of the hook body of the present utility model;

the components in the drawings are marked as follows: 1-grab handle, 11-antiskid part, 12-bending part, 2-connecting rod, 3-hook body and 4-hook tip.

Detailed Description

The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.

Referring to fig. 1 and 2, an embodiment of the present utility model:

a novel cervical vertebra retractor, comprising: grab handle 1, connecting rod 2, coupler 3, the both ends of grab handle 1 are all provided with connecting rod 2 in an integration, and two the top of connecting rod 2 all is provided with coupler 3 to the contained angle of coupler 3 and connecting rod 2 is less than 90.

In order to make the contact surface of the hook body 3 with the skin of the patient smoother, the surface is provided with a convex curved surface.

The topmost end of the hook body 3 is provided with a bent hook tip 4, and the hook tip 4 can prevent the drag hook from sliding off when in use.

The two sides of the grab handle 1 are provided with hook bodies 3, and the sizes of the two hook bodies 3 are different.

Two sections of anti-skid parts 11 are arranged on the grab handle 1, and a bending part 12 is arranged between the two sections of anti-skid parts 11.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
