Abstract
The utility model discloses three-jaw foreign body forceps which comprise a handle, a slider, an outer tube, a draw cord and a head. A slide groove is formed in the handle, the slider is slidably mounted in the slide groove, the draw cord is nested inside the outer tube and is connected with the slider, the head is connected to a far end of the stay cord and comprises a three-jaw nose, and the nose comprises three jaws. Compared with the prior art, the three-jaw foreign body forceps have the advantages that the opening range of the nose is increased, and an opening degree of the nose can be selected according to the sizes of foreign bodies in human organs such as the stomachs and the intestines of patients; grabbed foreign bodies are fastened and are not easy to drop owing to spacing angles (which are 120 degrees) among the three jaws; the foreign bodies can be easily grabbed by medical staff by the aid of the three-jaw foreign body forceps owing to characteristics of the jaws.
Description
Technical field
The present invention relates to a kind of medical device technical field, particularly a kind of three-pawl type foreign body forceps.
Background technology
In medical device, the foreign body forceps on domestic market is basically all similar, the binding clip of foreign body forceps is mainly used for capturing and is difficult for the foreign body that takes out, but because of the complex manufacturing technology of binding clip, the more difficult control of open-width range size of jaw, comparatively difficult when capturing some larger foreign bodies.
The utility model content
The utility model proposes a kind of three-pawl type foreign body forceps, be mainly used for capturing and be difficult for the foreign body that takes out to have solved the binding clip of foreign body forceps in the prior art, but the complex manufacturing technology because of binding clip, the more difficult control of open-width range size of jaw, comparatively difficult technical matters when capturing some larger foreign bodies.
This utility model purpose is achieved through the following technical solutions:
A kind of three-pawl type foreign body forceps, comprise handle, slide block, outer tube, drag-line and binding clip, handle is provided with sliding tray, slide block is slidably mounted in sliding tray, drag-line is set in outer tube inside, and slide block is connected with drag-line, and the drag-line far-end connects binding clip, described binding clip comprises the Three-claw type jaw, and described jaw consists of three chelas.
Preferably, described chela comprises first end and the second end, and the first end of described three chelas is welded to connect, and the second end is separated from each other and is opening-like.
Preferably, described chela pitch angle each other is respectively 120 °.
Preferably, described chela profile is arch, and the formation net shape that cooperatively interacts.
Preferably, the second end of described chela is provided with smooth end cap, and described end cap profile is solid spherical.
Preferably, described Three-claw type jaw is arranged on the outer tube end, and along with the mutual motion of handle and slide block is come in and gone out and folding in the booster end.
Compared with prior art, this utility model has following beneficial effect:
Three-pawl type foreign body forceps of the present utility model, the folding amplitude range of its jaw increases, the large I of its open-width is chosen according to the size of foreign body in the human organs such as patient's gastrointestinal, and between three-jaw between angle (pitch angle is 120 °) can be more firm while being also the foreign body in order to have captured, difficult drop-off, and its chela feature is also in order to make the medical worker more easily capture foreign body.
The accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of three-pawl type foreign body forceps structural representation of the present utility model;
The tong head schematic diagram that Fig. 2 is this utility model dress.
The specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is only this utility model part embodiment, rather than whole embodiment.Embodiment based in this utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of this utility model protection.
Please refer to accompanying drawing 1-2, a kind of three-pawl type foreign body forceps, comprise handle 1, slide block 2, outer tube 3, drag-line 4 and binding clip 5, handle 1 is provided with sliding tray 11, slide block 2 is slidably mounted in sliding tray 11, drag-line 4 is set in outer tube 3 inside, slide block 2 is connected with drag-line 4, drag-line 4 far-ends connect binding clip 5, and described binding clip 5 comprises the Three-claw type jaw, and described jaw consists of three chelas 51, wherein, chela 51 comprises first end 511 and the second end 512, and the first end 511 of described three chelas 51 is welded to each other connection, and the second end 512 is separated from each other and is opening-like; Can be more firmly and difficult drop-off for the foreign body that makes to capture, described chela 51 pitch angle each other is respectively 120 °, and described chela 51 profiles are arch, and cooperatively interact and form the net shape, can make foreign body be easy to melt and put in net inside.
For fear of chela, 51 couples of patients cause extra injury, and the second end 512 of described chela 51 is provided with smooth end cap 513, and described end cap 513 profiles are solid spherical.
Further, the Three-claw type jaw is arranged on outer tube 3 ends, and, along with the mutual motion of handle 1 and slide block 2 is come in and gone out and folding in booster 3 ends, the large I of its jaw folding is the scope control in the sliding tray 11 interior movements of handle 1 by slide block 2.
Comprehensive above-mentioned structure of the present utility model is known, three-pawl type foreign body forceps of the present utility model, the folding amplitude range of its jaw increases, the large I of its open-width is chosen according to the size of foreign body in the human organs such as patient's gastrointestinal, and between three-jaw between angle (pitch angle is 120 °) can be more firm while being also the foreign body in order to have captured, difficult drop-off, and its chela feature is also in order to make the medical worker more easily capture foreign body.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
