Abstract
The utility model discloses a propulsion unit for a small needle knife. The propulsion unit comprises a jacket body that has scales on the surface, wherein the jacket body is internally provided with a sliding block that can slide up and down along the inner wall of the jacket body; the upper surface of the sliding block is connected with a push rod of a handle; the lower surface of the sliding block is connected with a barrel by a spring; and the barrel can be inserted and connected with a needle handle of the small needle knife into one. Further, the spring is the compression spring. Still further, the jacket body is made of transparent rigid plastic. The propulsion unit has the benefits that with the adoption of the structure, the push rod can be pushed by the handle to move to drive the sliding block to move, so as to push the barrel to drive the small needle knife to move, therefore, the small needle knife can be pushed in fast, thereby avoiding the pain in the needle inserting process; in addition, the scales are arranged on the surface of the jacket body, so as to push the small needle knife in accurately.
Description
(1) technical field
This utility model relates to a kind of small needle knife propulsion plant, belongs to medical instruments field.
(2) background technology
Small needle knife is used for the tissue of adhesion is peeled off in clinical, the retardance mediation, but because the diameter of pin cutter is thicker, when undergoing surgery, because of inserting needle slow, in the process that breaks through corium, have intensive pain, there is not suitable device to be used for small needle knife is advanced corresponding position fast and accurately on the market at present.
(3) summary of the invention
The technical problems to be solved in the utility model provides a kind of small needle knife propulsion plant, can fast and accurately small needle knife be pushed, and avoids the pain in the inserting needle process, and convenient and practical.
In order to solve the problems of the technologies described above, this utility model is realized by following measure:
A kind of small needle knife propulsion plant, comprise that the surface is provided with graduated body, be provided with the slide block that can slide up and down along its inwall in the described body, this slide block upper surface is connected with the push rod that has handle, the lower surface of slide block connects cylindrical shell by spring, and this cylindrical shell can be pegged graft with the needle handle of small needle knife and is one.
Further, spring is the compression spring.
Further, described body is that transparent rigid plastics is made.
The beneficial effects of the utility model:
After adopting said structure, promote pushrod movement by handle and drive slide block movement and then promote cylindrical shell and drive the small needle knife motion, can fast small needle knife be pushed, avoid the pain in the inserting needle process, and the surface of body is provided with scale, can accurately small needle knife be pushed.
