Abstract
The invention relates to a pair of lockable thumb push-pull slide block biopsy forceps. The pair of lockable thumb push-pull slide block biopsy forceps is characterized by consisting of a forceps head, a hose, a slide block, a locking screw and a handle, wherein the locking screw is embedded into the side face, relative to the slide block by an angle of 90 degrees, of the middle part of the handle; the slide block is a push-pull side block, and is H-shaped; the sizes of two symmetrical longitudinal surfaces of the slide block are consistent with the thumb proportion of a normal adult; the transverse surface of the slide block is contacted with the tail end of the locking screw. The pair of lockable thumb push-pull slide block biopsy forceps is simple in structure, has high reliability, and is convenient to use. After sampling, the forceps can be locked to prevent a sampled object from falling, and meanwhile the difficulty in pulling the sampled object back can be lowered.
Description
Technical field
The present invention relates to a kind of biopsy forceps.
Background technology
Under scope, biopsy is to find early stage digestive tract pathological changes, understands an important method of digestive tract pathology pathological changes.Biopsy forceps is conventional movable detecting apparatus.Existing product handle slider designs is used very inconvenient, in the time of gripping, very easily because operate miss causes landing, causes sampling unsuccessfully.And because biopsy forceps length is longer, it is very constant that medical personnel take out the operation of sampling thing, and slightly general idea sampling thing just will drop and need resample, and increase patient and medical personnel's double burden.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of simple and reasonable, good reliability, easy to use, can locking after sample to prevent that getting thing drops, the while can be reduced the biopsy forceps of getting the difficulty of pulling back after thing.
Technical scheme of the present invention is achieved in that one can the plug-type slide block biopsy forceps of locking thumb, it is characterized in that, by binding clip, flexible pipe, slide block, lock bolt and handle composition, lock bolt is intercalated on the side of handle middle part with respect to slide block an angle of 90 degrees, and described slide block is plug-type slide block, is H type, two symmetrical longitudinal surface size is consistent with normal adult thumb ratio, and athwartship plane contacts with lock bolt end; Slide block length is greater than the range of convergence that slide block and lock bolt end can contact friction points.
Thumb control slide block, freely to control the folding of binding clip, samples more reliable; While getting after thing success screw-driving, the frictional force of tip of screw and slide block can ensure that slide block no longer moves axially, thereby by the position of binding clip and angle locking, prevent that sample from dropping, then abandon handle control, both hands take out sample pickup tongs from human body, have reduced and have got the thing difficulty of pulling back; Lock bolt is intercalated on the side of handle middle part with respect to slide block, is convenient to rotary screw in the time of operation; Slide block length is greater than the range of convergence that slide block and lock bolt end can contact friction points, can ensure that slide block can carry out locking with lock bolt moving forward and backward any position, has increased the reliability of medical procedure.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the cutaway view of A-A face in Fig. 1.
In figure: 1, binding clip; 2, flexible pipe; 3, slide block; 4, hands handle; 5, lock bolt.
Detailed description of the invention
Embodiment 1, one can the plug-type slide block biopsy forceps of locking thumb, as shown in Figure 1 and Figure 2, it is characterized in that, by binding clip 1, flexible pipe 2, slide block 3, lock bolt 5 and handle 4 form, lock bolt 5 is intercalated on the side of handle 4 middle parts with respect to an angle of 90 degrees of slide block 3, and described slide block 3 is plug-type slide block, is H type, two symmetrical longitudinal surface size is consistent with normal adult thumb ratio, and athwartship plane contacts with lock bolt 5 ends; Slide block 3 length are greater than the range of convergence that slide block 3 and lock bolt 5 ends can contact friction points.
In use slide up and down by thumb control slide block, to control the folding gripping thing sample of binding clip, obtain after required thing sample screw-driving, keep the closed condition of binding clip, then abandon the control of handle sample pickup tongs is taken out from human body.
Claims (2)
- One kind can the plug-type slide block biopsy forceps of locking thumb, it is characterized in that, by binding clip, flexible pipe, slide block, lock bolt and handle composition, lock bolt is intercalated on the side of handle middle part with respect to slide block an angle of 90 degrees, and described slide block is plug-type slide block, is H type, two symmetrical longitudinal surface size is consistent with normal adult thumb ratio, and athwartship plane contacts with lock bolt end.
- 2. one according to claim 1 can the plug-type slide block biopsy forceps of locking thumb, it is characterized in that, slide block length is greater than the range of convergence that slide block and lock bolt end can contact friction points.
