Description
Technical field
This utility model relates to a kind of pathological analysis operating theater instruments sample pickup tongs, relates to a kind of jaw auto-reset type sample pickup tongs specifically, belongs to medical instruments field.
Background technology
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 enter in tissue cause scrape injured tissue and picked-up tissue after cause tissue loss to cause repeat surgery, bring inconvenience to operation undoubtedly.A kind ofly need not implement to apply external force so can design and keep the sample pickup tongs that jaw is closed, the safety and stability and efficiency that facilitate medical worker to perform the operation fast to improve apparatus.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, provides a kind of jaw auto-reset type sample pickup tongs, it under normal conditions jaw be in closure state all the time, apply external force promote slip ring time jaw just can open.Thus achieve medical worker and fast and safely 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:
A kind of jaw auto-reset type 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 slip ring, described slip ring is connected by pulling device with between binding clip, is provided with the automatic reset device allowing pulling device reset in described clamp block.
Below the further optimization of this utility model to such scheme:
Pulling device comprises two connecting rods hinged with two binding clip one_to_one corresponding respectively, is provided with small rod in described clamp block, and wherein one end of small rod is by the second bearing pin and two rod hinge connections;
Further optimization: the rear end of described clamp block is fixedly connected with trocar sheath, the front end of handle is fixedly connected with sleeve pipe, and described trocar sheath is away from one end of clamp block and telescopic joint;
Further optimization: described slip ring is connected with pull bar by retainer ring, described pull bar is positioned at handle, and described pull bar is connected by drag-line with between small rod.
Further optimization: described automatic reset device comprises and is arranged in clamp block and is sleeved on the spring of small rod outside, and the rear end of small rod is fixedly connected with the stator for stopping restraining spring.
This utility model takes automatic reset device to make it automatically be in normally off for binding clip.Because clamp block and trocar sheath and handle are connected and fixed rear formation overall fixed body, and pull bar and drag-line, slip ring are connected and fixed rear formation moving body, so when pulling slip ring, binding clip will realize the closed of jaw.This utility model uses spring automatic spring indirectly to pull lower link bar thus acted on jaw, realizes the normally off of jaw, reliably safe and effective; This utility model compact conformation is stablized, and apparatus has good stability.
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
Embodiment, as shown in Figure 1 and Figure 2, a kind of jaw auto-reset type sample pickup tongs, comprise the clamp block 5 of a hollow, the front end of described clamp block 5 is connected with can opening and closing thus realize carrying out tissue two binding clips 1 of gripping, and the rear end of described clamp block 5 is connected with handle 17, and handle 17 slidably connects slip ring 16, described slip ring 16 is connected by pulling device with between binding clip 1, is provided with the automatic reset device allowing pulling device reset in described clamp block 5.
Described two binding clips 1 are rotationally connected with clamp block 5 by the first bearing pin 2.
Pulling device comprises two connecting rods 3 hinged with two binding clip 1 one_to_one corresponding respectively, is provided with small rod 6 in described clamp block 5, wherein one end of small rod 6 by the second bearing pin 4 and two connecting rods 3 hinged;
The both sides of described clamp block 5 have the side groove being convenient to connecting rod 3 slide anteroposterior.
The rear end of described clamp block 5 is fixedly connected with trocar sheath 10, and the front end of handle 17 is fixedly connected with sleeve pipe 12, and described trocar sheath 10 is connected with sleeve pipe 12 away from one end of clamp block 5.
Described slip ring 16 is connected with pull bar 14 by retainer ring 15, and described pull bar 14 is positioned at handle 17, and described pull bar 14 is connected by drag-line 11 with between small rod 6.
Described automatic reset device comprises and is arranged in clamp block 5 and is sleeved on the spring 7 of small rod 6 outside, and the rear end of small rod 6 is fixedly connected with the stator 9 for stopping restraining spring 7, is provided with pad 8 between stator 9 and spring 7.
Trocar sheath 10 one end is inserted with being welded and fixed in clamp block 5, and one end is inserted the interior glue of sleeve pipe 12 and fixed.Pull bar 14 one end being provided with drag-line 11 is inserted in the side opening of retainer ring 15, and makes it be out of shape at suitable position flattening pull bar 14, limits moving and coming off of retainer ring 15.
