Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of Linear stapler that is provided with safety.
Background technology
In medical science applied surgical operation, since the first staple series products of the sixties in 20th century comes out, the various surgeries of requisite a kind of medical apparatus and instruments that the medical linear stiching instrument has become in the auxiliary edge of a knife sewing process are widely used in stitching human body alimentary canal tissue, respiratory tissues and vascular tissue with Linear stapler in surgical operation, can reduce operating time, improve the operation quality.They are used to the end ends such as esophagus in the digestive tract, Stomach duodenum, small intestinal, coton and rectal, distolateral and side-to-side neurorrhaphy operation, and hemorrhoid excisions stomach function regulating pylorus is made in mouthful operation that waits formation passage or close incisions, also be used to the suture operation of the suture operation such as lung and trachea in the respiratory tract and vascular tissue, be specially adapted to appear the suture operation with the Organ and tissue of operating difficulties.
Use existing Linear stapler suture tissue, when stiching instrument was in original state, nail supporting base separated with nail bin groupware, and tissue to be sewed up is placed between nail bin groupware and the nail supporting base; Then, hold firing handle, so that nail bin groupware draws close to the nail supporting base direction, and release staple in the nail bin groupware by the effect of propulsion plant, thereby finish sew application; At last, decontrol firing handle, propulsion plant returns to original state with nail bin.Because lacking safety, Linear stapler can occur without the situation that nail is pulled the trigger or mistakenly hit is sent out, thereby have influence on normally carrying out of operation, even can cause operative failure in the process of using.
This shows, above-mentioned existing Linear stapler exists obvious deficiency and defective, and demand urgently further being improved, how to found a kind of can the appearance without the Linear stapler that is provided with safety that nail is pulled the trigger or mistakenly hit is sent out, improved target is badly in need of in the current this area of real genus.
The utility model content
The technical problems to be solved in the utility model provides a kind of Linear stapler that is provided with safety, make it after finishing the percussion operation, nail bin groupware can not be repeated percussion, only after correctly being installed, new nail bin groupware just can operate, and apparatus automatically locks, need not manually-operated, can not occur without the situation that nail is pulled the trigger or mistakenly hit is sent out, thereby overcome the deficiencies in the prior art.
For solving the problems of the technologies described above, this utility model provides a kind of Linear stapler that is provided with the New-safety device, comprise jaw support, nail supporting base assembly, nail bin groupware, coupling assembling, propulsive mechanism, firing lock and safety, wherein: propulsive mechanism comprise clamping plate and can before and after slide be installed in nail pushing plate between two clamping plate; The clamping plate of safety and propulsive mechanism are flexibly connected, front end is provided with when not having nail bin the stopping means that the restriction nail pushing plate advances and remove the restriction that nail pushing plate is advanced after inserting nail bin, and the rear end is equipped with the resetting means that makes described stopping means remain on the position that the restriction nail pushing plate advances when not having nail bin.
As further improvement of the utility model, the middle part of described safety and the clamping plate of propulsive mechanism are rotatably connected, and described stopping means is a stop hook, and the front end of described nail pushing plate is not stuck in the stop hook when having nail bin.
Described resetting means is that an end is fixedly connected with the back-moving spring that the clamping plate of the other end and propulsive mechanism offset with the rear end of safety.
Described jaw frame bottom is provided with containing cavity, and safety namely are positioned at this containing cavity.
Described safety are rotatably connected by the clamping plate of bearing pin and propulsive mechanism.
Described safety are the safety block of S shape.
After adopting above design, after using this utility model to finish the percussion operation, nail bin groupware can not be repeated percussion, only after correctly being installed, new nail bin groupware just can operate, and apparatus automatically locks, need not manually-operated, situation about sending out without nail percussion or mistakenly hit can not occur, thus carrying out smoothly of can guaranteeing to perform the operation.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Above-mentioned only is the general introduction of technical solutions of the utility model, and for can clearer understanding this utility model, the utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
Fig. 1 is the structural representation of existing Linear stapler.
Fig. 2 is that this utility model is installed the front stiching instrument head cross-sectional view of nail bin.
Fig. 3 is stiching instrument head cross-sectional view behind this utility model installation nail bin.
The specific embodiment
In the following description, for convenience of description, will when using apparatus, be called the rear end by the end near the operator, be called front end away from operator's a end.
See also Fig. 1 to shown in Figure 3, a kind of Linear stapler that is provided with safety of this utility model, be on the basis of existing jaw support 1, nail supporting base assembly 2, nail bin groupware 3, coupling assembling 4, propulsive mechanism 5 and firing lock 6, set up safety 7.
Specifically, propulsive mechanism of the present utility model 5 mainly by clamping plate and the fit structure by chute, bearing pin can before and after two nail pushing plates between the clamping plate that are installed in that slide form, and can be designed with at the clamping plate of propulsive mechanism 5 as shown in the figure cervical part of esophagus arcwall face.
The clamping plate of the middle part of safety 7 of the present utility model and propulsive mechanism 5 are rotatably connected, and front end is provided with the stop hook corresponding with the nail pushing plate front end face 71, and the rear end is equipped with resetting means 72.
In addition, also can be provided with containing cavity in the bottom of jaw support 1, safety namely are positioned at this containing cavity, and can move in this containing cavity, rotate, thereby make the mechanism of stiching instrument compacter.
During use, install before the nail bin groupware 3, safety 7 are under the effect of leaf spring 72, stop hook 71 is in upper, and the head of the nail pushing plate of propulsive mechanism 5 is stuck in the stop hook 71, and nail pushing plate can't move forward, also can't hold the firing handle of firing lock 6, be without the spike attitude this moment.
In the process of jaw closure, safety 7 move forward with propulsive mechanism 5.
When to the jaw support 1 interior installation nail bin groupware 3 of Linear stapler, nail bin groupware 3 from top to bottom inserts the clamping plate head of propulsive mechanism 5, and after being in place, nail bin groupware 3 promotes stop hook 71 downwards, safety rotate counterclockwise around bearing pin, and the head bottom of nail pushing plate breaks away from stop hook 71.At this moment, when holding the firing handle of firing lock 6, nail pushing plate can move forward the percussion staple.
After percussion is finished, lay down nail bin groupware 3, safety 7 are under the effect of leaf spring 72, and the initial position that automatically rebounds props up nail pushing plate, and apparatus is in safety position.
The above; it only is preferred embodiment of the present utility model; be not that this utility model is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in the protection domain of the present utility model.
