Description
Technical field
This utility model relates to medical apparatus and instruments, and relating to one specifically can automatically reset tissue sample pickup tongs, belongs to technical field of medical instruments.
Background technology
Sample pickup tongs is used to gather living tissue sample in the human bodies such as oral cavity, digestive tract, respiratory tract, to be supplied to the special equipment of pathological analysis.
At present, pathological analysis operating theater instruments sample pickup tongs conventional in surgical operation, essentially no automatic jaw is without reset function, must exert pressure when operating and pull slip ring that jaw is closed, prevent from scraping injured tissue entering in tissue to cause, and cause tissue loss, to make troubles to operation after picked-up tissue.If design a kind of external force that need not apply to keep the sample pickup tongs that jaw is closed, medical worker is facilitated to perform the operation fast, to improve safety and stability and the efficiency of apparatus, very necessary.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, there is provided one can automatically reset tissue sample pickup tongs, can realize medical worker fast and safely to sample in patient body, situation about coming off after need not worrying to scratch patient tissue and picked-up tissue occurs.
In order to solve the problem, this utility model by the following technical solutions:
One can automatically reset tissue sample pickup tongs, comprise the clamp block of a hollow, the front end of described clamp block is connected with can opening and closing thus realize carrying out tissue two binding clips of gripping, the rear end of described clamp block is connected with handle, handle slidably connects sliding sleeve, and described sliding sleeve is connected by pulling device with between binding clip, and the front end of handle has tubular support portion, in described tubular support portion, there is cavity, the automatic reset device allowing two binding clips reset is installed in described cavity.
Below the further optimization of this utility model to such scheme:
Described two binding clips are rotationally connected by the first bearing pin and clamp block.
Pulling device comprises two connecting rods hinged with two binding clip one_to_one corresponding respectively, is provided with the first pull bar in described clamp block, and wherein one end of the first pull bar is connected with two connecting rods by the second bearing pin;
Described sliding sleeve is connected with the second pull bar by retainer ring, and described second pull bar is positioned at handle and is also connected with the first pull bar through the cavity in tubular support portion.
The rear end of described clamp block is connected by trocar sheath with between the end in tubular support portion.
Described automatic reset device comprises the spring in the cavity being arranged on described tubular support portion, and spring is fixedly connected with spring stop near one end of clamp block, and described spring stop is fixedly connected with the second pull bar.
This utility model takes automatic reset device to make it automatically be in normally off for binding clip.When pulling sliding sleeve, binding clip will realize the closed of jaw, and when unclamping sliding sleeve, binding clip under the action of the spring, is in open configuration, is convenient to clamping tissue.This utility model is reliably safe and effective; After binding clip grasping tissue, do not need external force, can automatically make binding clip be in open configuration, prepare gripping object at any time, this utility model compact conformation be stablized, and has good stability.Can realize medical worker fast and safely to sample in patient body, situation about coming off after need not worrying to scratch patient tissue and picked-up tissue occurs.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
