Abstract
The utility model discloses a kind of hysteroscope firing handle to close stretching mechanism, the opening and closing mechanism includes housing, the firing handle being connected with housing, it is connected with firing handle and is located at the lever in housing and safety fastener, the snap-on being connected with safety fastener, the ratchet being connected respectively with lever and has strong market potential, with the ratchet button that is connected of having strong market potential, the Saw blade being connected with ratchet button, the safety plug being connected with ratchet.This product has the advantage that compared with prior art：It is adapted to one-handed performance, it is easy to operate.
Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of new hysteroscope firing handle closure stretching mechanism.
Background technology
In recent years, many Progress ＆ New Products have a great development laparoscopic surgery, have the abdominal cavity of minimally invasive effect
Mirror has played very big effect in the diagnosis and treatment of belly.For a laparoscopic procedure person, stitched under laparoscope
Close, knot, hemostasis is probably most important.During traditional abdominal operation, suture, knotting, the hemostasis of maneuverability need
Want operator to have very expertly technical operation and experience, and can not realize that line is passed in continuous feeding in operating process, operate
Discontinuously, increase operating time, increase patient infection risk, and the switching function of apparatus be by bimanualness,
Both nail bin was operated by stabbing card device into, before abdominal cavity the stitching unstrument nail bin need to close into after abdominal cavity, then with another hand
The tissue that need to be cut off is clamped after nail bin is opened, then is operated, it is more inconvenient to operate.
Utility model content
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides one kind and is easy to singlehanded behaviour
The new hysteroscope firing handle closure stretching mechanism made.
Technical scheme：A kind of in order to solve the above technical problems, new hysteroscope firing handle closure provided by the utility model
Opening mechanism, the opening and closing mechanism include housing, the firing handle being connected with housing, are connected with firing handle and are located at housing
Interior lever and safety fastener, the snap-on being connected with safety fastener and are had strong market potential at the ratchet being connected respectively with lever, with the spine that is connected of having strong market potential
Tooth button, the Saw blade being connected with ratchet button, the safety plug being connected with ratchet.
Further, the Saw blade tail end is provided with a reset button.
Further, a tripping is provided with above the Saw blade, the effect of tripping is:When cartridge component is loaded into the apparatus
When, the afterbody of cartridge component promotes the coupling mechanism in apparatus to open tripping simultaneously, so that tripping departs from the lock of ratchet bar
Oral area position, now firing handle can normal work.
In the utility model, safety plug and two associated parts that safety fastener is in the apparatus, snap-on and safety fastener
Connection and snap-on can be made slightly to revolve position rotation.In first time pinching handle, safety plug in a state of nature, now firing handle
In position of coming to nothing, promote to the left or to the right at the screens on safety plug to safety fastener, now firing handle resets, so far repeatedly
Pinching firing handle is until stroke terminates.Saw blade is when being clasped by the ratchet in firing handle, is incited somebody to action by pinching firing handle
Saw blade promotes forward.
Beneficial effect：The utility model possesses advantages below in terms of existing technologies：
New hysteroscope firing handle closure stretching mechanism provided by the utility model, in use, apparatus, which is put into, to be needed to cut off
The position of tissue, then pinching firing handle are sutured to clamp tissue, and whether the tissue for observing closing is suitable, now snap-on is caught in
Saw blade limited mouth, after confirming that safety is suitable, after pressing " safety plug ", snap-on releases Saw blade limited mouth by pressure, pinches repeatedly
Dynamic " firing handle ", ratchet mutually act with Saw blade repeatedly, make Saw blade promote cutter to advance, complete the cutting of tissue with
Suture.After the completion of action, reset button is retracted into home position again, opens nail bin groupware, apparatus moved to safe without device
Apparatus, after pinching " firing handle " closes nail bin groupware again, human body, whole process are withdrawn from by whole by the room of official's tissue
Unmarried operation is only needed, it is easy to operate simple.
Brief description of the drawings
Fig. 1 is that the utility model uses pre-structure schematic diagram.
Fig. 2 is that opening and closing mechanism uses preceding enlarged diagram.
Fig. 3 is that the utility model uses rear structural representation.
Fig. 4 is that opening and closing mechanism uses rear enlarged diagram.
Wherein：16. levers 17. 10. the ratchet button 15. of 13. snap-on of Saw blade 11. tripping, 12. ratchet 14. is had strong market potential
The firing handle of 18. safety plug of safety fastener, 19. reset button 20..
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Fig. 1 ~ 4, a kind of new hysteroscope firing handle closure stretching mechanism, the opening and closing mechanism includes housing,
The firing handle 20 being connected with housing, it is connected with firing handle 20 and is located at the lever 16 in housing and safety fastener 17, with insurance
The connected snap-ons 13 of button 17, the ratchet 12 being connected respectively with lever 16 and have strong market potential 15, and 15 ratchet buttons 14 being connected of having strong market potential, with spine
The connected Saw blade 10 of tooth button 14, the safety plug 18 being connected with ratchet 12.The tail end of Saw blade 10 is provided with a reset button 19.Institute
State the top of Saw blade 10 and be provided with a tripping 11.
In the present embodiment, apparatus is put into the position for needing to cut off suture tissue, stirs angular adjustment knob and be rocked to institute
Angle, then pinching firing handle 20 is needed to clamp tissue, and whether the tissue for observing closing is suitable, now snap-on 13 is caught in Saw blade
10 limited mouths.After confirming that safety is suitable, press that " after safety plug button 18 ", snap-on 13 releases Saw blade limited mouth by pressure, instead
" firing handle 20 ", ratchet 12 mutually act with Saw blade 10 repeatedly, make Saw blade 10 promote cutter to advance, and complete for multiple pinching
The cutting and suture of tissue, midway never hesitate and paused.After the completion of action, reset button 19 is retracted into home position again, makes nail bin
Component opens, and apparatus is moved to the safe room without organ-tissue, pinching firing handle 20 closes nail bin groupware again
Afterwards, apparatus is withdrawn from human body by whole, whole process only needs one-handed performance, simple and convenient.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
