Abstract
Disclosed is a surgical round tube type stapler. A technique modification is carried out on a safety bolt by dividing the bolt into two segments or making the safety bolt cooperate with a fixation rod or a stapler handle. The safety bolt can't reset after the stapler is triggered so as to prevent the stapler being triggered for the second time automatically and avoid damage of a stapler ring caused by misoperation of doctors during operations. The disclosed stapler is provided with a simple and practical structure, a small number of parts, easy assembly, convenience for using, and high security.
Description
Technical field
This utility model relates to Binding Instrument, especially the tubular type binding instrument that surgical operation uses, and is in particular a kind of tubular type binding instrument that is provided with anti-secondary firing lock, belongs to technical field of medical instruments.
Background technology
Binding device for surgery is a kind of medical apparatus and instruments that often uses when physiological tissues such as intestinal are carried out surgical operation, and the difference of this instrument performance plays crucial effects for the whole surgery effect.For preventing the mistake percussion, generally be provided with safety on the Binding Instrument.In the prior art, the mode of operation of safety mostly is greatly manually above the tubular type binding instrument, and the doctor just opens insurance, implements the percussion bookbinding when performing an operation to the patient after every preparation is finished.The actual use finds that there is following defective in this safety: if the doctors experience deficiency, the surgical binding operation also can be opened and implement to safety when not in place in the bookbinding gap, causes surgical effect not good; Perhaps, if forget the insurance of closing when changing the outfit the Binding Instrument head assembly, careless slightlyly will press the percussion spanner, binding needle will hit from the instrument head assembly, causes operative failure.And the doctor who has causes tissue broken by folder for preventing that percussion may not pulled the trigger fully once more.
Chinese patent 98121969 adopts a spring to make the stop button self-return prevent to pull the trigger again, and its shortcoming is: spring is positioned at that this is external, and the danger that clips to tissue is arranged, and stop button also is against on the screw mandrel, easily the screw mandrel bending.Just because of this, according to the knowledge of the applicant, the actual at present Binding Instrument that uses all is not provided with anti-secondary percussion lock.
Summary of the invention
The purpose of this utility model is exactly in order to solve the above-mentioned problems in the prior art, and a kind of tubular type binding instrument that is provided with anti-secondary firing lock is provided, and makes operation more safe and reliable.
The purpose of this utility model is achieved through the following technical solutions:
Be provided with the tubular type binding instrument of anti-secondary firing lock, comprise Binding Instrument body, crimp head, firing lock and driving regulating mechanism, the outermost layer of Binding Instrument body is a shell, firing lock comprises handle and ejector pin bar, the handle head lamp brush guard pivot connects lock, it is characterized in that: be provided with the anti-secondary firing lock that the firing lock that can stop this Binding Instrument is pulled the trigger once more above the described lock.
The purpose of this utility model can also come further to realize by the following technical programs:
The above-mentioned tubular type binding instrument that is provided with anti-secondary firing lock, wherein, described anti-secondary firing lock is, this instrument also is provided with fixed bar, the head of fixed bar and this tool housing are provided with the barb of mutual coupling, are connected for ratchet, ratchet or pair of friction components mode between fixed bar and the lock.Perhaps, described lock is divided into two sections, and this end of two sections links to each other by pivot and forms folding shape structure, and this centre of two sections also is provided with the connection spring.Perhaps, the afterbody of described lock is provided with projection, and the relevant position of instrument handle is provided with recess.
Like this; this utility model is by carrying out technological improvement to lock; lock is divided into two sections; lock is matched with fixed bar or instrument handle; the normal return of lock after instrument is pulled the trigger; make this instrument to stop automatically and pulled the trigger once more, play the technique effect of anti-secondary percussion, thereby avoid damaging binder ring because of maloperation in doctor's operation process.This apparatus structure is simple and practical, and few, the easy assembling of part is easy to use, the security performance height.
Description of drawings
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.In the middle of these accompanying drawings,
Fig. 1 is this utility model overall appearance sketch map;
Fig. 2 a, 2b are the structural representations of first kind of embodiment of this utility model;
Fig. 3 a, 3b are the structural representations of another embodiment of this utility model;
Fig. 4 a, 4b are the structural representations of another embodiment of this utility model.
The implication of each Reference numeral is among the figure:
The 31-shell, 32-handle, 33-pulling-on piece, 34-lock, 35-fixed bar;
The 41-handle, 42-screw mandrel, 43-pulling-on piece, 44a/b-lock, 45-spring, 46-lock, 47-spring, 48-projection.
The specific embodiment
This utility model surface structure as shown in Figure 1.In the prior art, be provided with drag hook between the handle of this type of medical apparatus and instruments and the ejector pin bar afterbody, for reaching the purpose of anti-secondary percussion, the simplest way is this drag hook of cancellation, but this way can make the overall package of instrument be affected, difficulty increases, and therefore, anti-secondary firing lock need be set specially on the instrument internal structure.For this reason, this utility model is conceived to the lock of instrument, has proposed a plurality of specific embodiment under the situation of whole thinking unanimity.
Among Fig. 2 a and the 2b, lock 34 is pivotally connected on handle 32 by pin, and is connected for ratchet between the fixed bar 35; The fixed bar head has a barb, and the barb that cooperates is with it arranged on the shell 31.When initial, the head of fixed bar 35 is against above the pulling-on piece 33; Retreat when screw mandrel drives pulling-on piece 33, discharge fixed bar 35, can pull the trigger this moment; After the percussion, fixed bar 35 is owing to the effect of barb is fixed on above the shell 31, and ratchet makes fixed bar 35 can not reply with lock 34 mutual dislocation, plays anti-secondary percussion effect.Wherein, ratchet can change ratchet, friction pair non-response mechanisms such as (being similar to antenna) into, and its position can be arranged on instrument body afterbody.
Among Fig. 3 a and the 3b, lock is divided into two sections 44a and 44b, and their end links to each other by pivot and forms folding shape structure, and the position, intermediate portion links to each other by spring 45.When initial, the leading portion 44a of lock plays safety effect, inwardly pulls and opens after the insurance, and screw mandrel 42 drives pulling-on piece 33 and retreats; Unclamp handle 41 after finishing percussion, under the effect of spring 45, the back segment 44b of lock closes, and plays anti-secondary percussion effect.
Among Fig. 4 a and the 4b, be connected with spring 47 between lock 46 and the handle 41, the afterbody of lock 46 has individual projection 48, and what cooperate with it is recess on the handle 41.Open insurance percussion during use, unclamp handle 41 then, discharge insurance, lock 46 surpasses original position in the effect redoubling next time of spring 47, makes the projection 48 of lock 46 afterbodys block recess above the handle 41, reaches the purpose of anti-secondary percussion.Wherein, in the time of return, also can rotate 180 degree, allow the other end of lock 46 play anti-secondary percussion effect.
Above-mentioned specific embodiment only is a prominent example of using technical solutions of the utility model, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the claimed scope of this utility model.
