Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a telescopic adjustable holding handle for a surgery electric scalpel head. The telescopic adjustable holding handle for the surgery electric scalpel head consists of a scalpel handle, a middle tube, an outer tube handle, an electric scalpel head and deformation joints, wherein the outer tube handle is a circular tube of which the upper end is open; the lower end of the outer tube handle and the electric scalpel head are formed into a whole; and the lower end of the middle tube is in the outer tube handle and forms a movable fit relation with the outer tube handle. The lower end of the scalpel handle is in the middle tube and is in screw-thread fit with the inner wall of the middle tube. The side wall of the lower end of the middle tube is provided with three deformation joints respectively and mutually forming an angle of 120 degrees in the direction of the cross section of the middle tube. The interior of the lower end of the middle tube is a circular truncated cone-shaped space of which the lower part is small and the upper part is big. According to the telescopic adjustable holding handle for the surgery electric scalpel head, the length of the scalpel handle can be conveniently adjusted, and thus, the telescopic adjustable holding handle for the surgery electric scalpel head can be used for operating spaces with different sizes, and the movement accuracy of the electric scalpel head can be greatly improved. Meanwhile, the telescopic adjustable holding handle for the surgery electric scalpel head also has a technical effect of labor saving.

Description

Adjustable length electric surgical knife bit grab handle

Technical field

The present invention relates to technical field of medical instruments, particularly relate to a kind of adjustable length electric surgical knife bit grab handle.

Background technology

The grab handle of existing electric surgical knife bit is all sizing fixed length, and this position that electric knife head in operation process is arrived cannot control flexibly, and particularly in some narrow spaces, doctor obviously exists situation unable to do what one wishes in operation.

Summary of the invention

The present invention, for solving the deficiencies in the prior art, provides a kind of adjustable length electric surgical knife bit grab handle that can adjust shank length easily.

The scheme solving the technology of the present invention problem is: adjustable length electric surgical knife bit grab handle is made up of handle of a knife, middle pipe, outer tube handle, electric knife head and movement joint.Outer tube handle is the pipe that upper end opens wide, and lower end and the electric knife head of outer tube handle are as a whole, and the lower end of middle pipe to be in outer tube handle and to be in active relationship with outer tube handle.The lower end of handle of a knife to be in middle pipe and with the inwall of middle pipe with threaded engagement.The sidewall of middle pipe lower end there are three to be mutually the movement joint of 120 ° in the cross-sectional direction of middle pipe.The inside of middle pipe lower end is lower little large truncated cone-shaped space.During adjustment, first regulate the relative position relation of middle pipe and outer tube handle, pinch middle pipe again and rotate clockwise handle of a knife, after in the truncated cone-shaped space that handle of a knife lower end moves downward outer tube handle lower end, to be divided into the medial wall applying pressure of lower end to outer tube handle of pipe in trisection by movement joint, the relative position of middle pipe and outer tube handle is fixed by the frictional force that this pressure produces.

Adopt such scheme, following effect can be reached:

Because the present invention can regulate the length of handle of a knife easily, can be used for the working place of different size, greatly can improve the activity precision of electric knife head, also there is labour-saving technique effect simultaneously.

Detailed description of the invention

Below in conjunction with drawings and Examples, the invention will be further described.

Adjustable length electric surgical knife bit grab handle is made up of handle of a knife 1, middle pipe 2, outer tube handle 3, electric knife head 4 and movement joint 5.The pipe that outer tube handle 3 is opened wide for upper end, lower end and the electric knife head 4 of outer tube handle 3 are as a whole, and the lower end of middle pipe 2 to be in outer tube handle 3 and to be in active relationship with outer tube handle 3.The lower end of handle of a knife 1 to be in middle pipe 2 and with the inwall of middle pipe 2 with threaded engagement.The sidewall of middle pipe 2 lower end there are three to be mutually the movement joint 5 of 120 ° in the cross-sectional direction of middle pipe 2.The inside of middle pipe 2 lower end is lower little large truncated cone-shaped space.During adjustment, first regulate the relative position relation of middle pipe 2 and outer tube handle 3, pinch middle pipe 2 again and rotate clockwise handle of a knife 1, after in the truncated cone-shaped space that handle of a knife 1 lower end moves downward outer tube handle 3 lower end, to be divided into the medial wall applying pressure of lower end to outer tube handle 3 of pipe 2 in trisection by movement joint 5, the relative position of middle pipe 2 and outer tube handle 3 is fixed by the frictional force that this pressure produces.

Claims

1. an adjustable length electric surgical knife bit grab handle, by handle of a knife, middle pipe, outer tube handle, electric knife head and movement joint are formed, it is characterized in that: outer tube handle is the pipe that upper end opens wide, lower end and the electric knife head of outer tube handle are as a whole, the lower end of middle pipe to be in outer tube handle and to be in active relationship with outer tube handle, the lower end of handle of a knife to be in middle pipe and with the inwall of middle pipe with threaded engagement, the sidewall of middle pipe lower end there are three to be mutually the movement joint of 120 ° in the cross-sectional direction of middle pipe, the inside of middle pipe lower end is lower little large truncated cone-shaped space, the diameter of the upper end of described handle of a knife is greater than the diameter of handle of a knife lower end, there is an annular component on the top of handle of a knife, during adjustment, first regulate the relative position relation of middle pipe and outer tube handle, pinch middle pipe again and rotate clockwise handle of a knife, after in the truncated cone-shaped space that handle of a knife lower end moves downward middle pipe lower end, the medial wall applying pressure of lower end to outer tube handle of pipe in trisection will be divided into by movement joint, the relative position of middle pipe and outer tube handle is fixed by the frictional force that this pressure produces.
