Description
Technical field
This utility model relates to a kind of surgical operation and uses medical apparatus and instruments, particularly relates to a kind of percussion safety with the cutter stiching instrument.
Background technology
In the orthopaedic surgical operations operation, medical suturing instrument has become the requisite medical assistance apparatus in the tissue sewing process.Along with the development and the research and development of products of medical science, more and more multi-functional seam nail series products is applied to clinical, and the scope of application has related to every field such as gastrointestinal surgery, Genneral Surgery, thoracic surgery, Urology Surgery, gynecological, becomes one of doctor's necessary tool.The application of medical suturing instrument have in the operation hemorrhage less, operating time short, can reduce error hand-manipulated, avoid infection, postoperative function recovers plurality of advantages such as fast.
A kind of product commonly used is the straight cuts stiching instrument in the medical suturing instrument, is mainly used in the opening of sewing up cavity tissue, sews up mouth neatly and very firm, is not easy to take place the stitching stomatorrhagia.Initial straight line stiching instrument has only the function of stitching, after tissue apposition finishes, need the doctor manually unnecessary tissue to be sliced off, and the doctor is not easy to grasp the distance between line of cut and the stitching thread, and then causes line of cut irregular, and the risk that leakage blood takes place is very big.
Therefore, be directed to the operation of human body privileged sites, developed the stiching instrument that directly has cutter, for example Johson & Johnson produces triumphant way; It has remedied the shortcoming of straight line stiching instrument to a certain extent, can accomplish the action of sewing up and cutting simultaneously, and the apparatus bar is longer; Be provided with handle and trigger, make things convenient for the doctor to operate, than the traditional line stiching instrument; This apparatus can be saved doctor's operating time greatly, reduces amount of bleeding, improves success rate of operation.
But; The stiching instrument class apparatus of existing band cutting knife; All be on the basis of original straight line stiching instrument, at cutting knife of two row's suturing nail center fixed, the cut direction of cutting knife is vertical with sutural direction; Cutting knife under the effect of thrust with pushing slice of nail one in the same way the nail supporting base direction do single lengthwise movement, lean on longitudinally moment thrust will organize and organize following Equipment on turning-machine for setting-on cutting tools cut-out.The advantage of this structure is simple in structure, and shortcoming is an effort when cutting and organizing, and the cut edge is irregular, and the seam nail tilts to the direction of cutting knife easily, causes the molding of seam nail relatively poor, sews up defectives such as mouthful leakiness.
This shows that above-mentioned existing band cutter stiching instrument obviously still has inconvenience and defective, and demands urgently further improving in structure and use.How to found that a kind of percussion power is littler, the molding of seam nail is better and can prevent the percussion of secondary mistake, the band cutter stiching instrument of security insurance, real one of the current important research and development problem that belongs to.
Summary of the invention
The technical problem that this utility model will solve provides a kind of band cutter stiching instrument percussion safety, will lock fully after the percussion of band cutter stiching instrument, and whole apparatus can not be done any action, and firing action is accomplished.
For solving the problems of the technologies described above; A kind of band cutter of this utility model stiching instrument percussion safety; It is characterized in that comprising safety plate, go up lower connecting block, locating piece, adjustable plate, resetting block and reset to push away and turn round; Wherein: locating piece is provided with inner chamber, and the locating piece upper end offers groove, and the right side is provided with spring mounting hole; Last lower connecting block and adjustable plate are installed on the locating piece through the groove that is provided with, and an end and the resetting block of adjustable plate fix; Safety plate one end is connected with last lower connecting block upper end; Reset to push away to turn round and be installed on the resetting block through bearing pin.
As a kind of improvement of this utility model, the described lower connecting block of going up is made up of the round platform of different-diameter.
Described safety plate adopts " L " shape structure of upper end band barb, and the safety plate end also is provided with a draw-in groove.
