Structural characteristics of stapler
Stapling, including housing, center rod and tube, the center rod in push tube, center front end is equipped with screw cap, the back end through adjusting knob at the end of the connecting screw and shell, shell outer surface has inspired handle, inspire active connection handle through a hinge and shell, whose character is: described stapling with linkage, The three connecting rods are respectively connected with the excitation handle, the inner wall of the shell and the push tube, and one end of the three connecting rods is connected with the same movable hinge; The three connecting rods of the connecting rod mechanism include a power rod, a support rod and a moving rod; The power rod and the excitation handle are hinged; The movable hinge is connected between the supporting rod and the shell; The movable hinge is connected between the moving rod and the pushing tube. The stapler of the utility model has the advantages of simple structure, convenient operation and strong stability.
Digestive tract anastomat push rod connected to the annular cutter structure, including the push rod, and the push rod fixed connection of circular knife, described the outer edge of the circular knife set have more than one direction is arranged along the circumference of ejector pin, described one end of the push rod are circular knife are embedded, due to the push rod are embedded with one end of the circular knife, so circular knife with high concentricity of push rod, in the process of cutting organization, The ring knife can sit in the middle smoothly and the operation success rate is high.
Structural characteristics of alimentary canal stapler
Digestive tract anastomat ejector pin of the device, including 6 nail warehouse ontology, ejector pin 1 of ontology, the first side wall hole 5 nail storehouse 7 at both ends of the department with the first guide wall 9 respectively, the second side wall 8 at both ends of the department has a 10 second guide wall respectively, the same the first guide wall 9, 10 second guide wall intersection and intersect arc transition, The first guide wall 9 and the second guide wall 10 at the same end are arranged on a relative scale; When there is a small change in the geometry of the stitching, it can also be safely located in the hole of the stitching bin by the role of the guide wall, to ensure that the width of the push nail sheet is greater than the width of the stitching crown, so that the stitching shape is good.
The connecting structure of the puncture cone and the nail seat of the digestive tract stapler includes a nail seat and a puncture cone. The nail seat is fixed with a clamp spring, and the puncture cone is inserted between the clamp springs, and the clamp spring clamps the puncture cone. Depending on the spring clamping force of the clamping spring, the nail seat can be reliably connected or separated from the puncture cone, which is safe to use and convenient to install.
Digestive tract anastomat double speed regulating device, including stapling ontology, and described the stapling ontology can turn to connect switch ontology, ontology and described knob connected with screw thread, the screw plug of stapling ontology are described in the inner chamber, the front of the screw rod is connected with stapling in this cavity in the body center, The screw has a first thread segment and a second thread segment connected, and the pitch of the first thread segment is greater than that of the second thread segment. It can quickly shorten the distance between the nail bin and the nail seat, and then the second thread segment slides relative to the knob body, which makes the screw move slower when the knob is rotated, which is beneficial to the operation of digestive tract.
The adjusting knob of alimentary canal stapler comprises a knob body, which is rotatably connected with the stapler body, and the knob body is threaded and connected with a screw; The knob body is provided with a radial convex part with radial enlargement, and the radial convex part has at least two. Radial lug boss makes knob butterfly, push with your fingers when using the radial lug boss, can be directly obtained moment makes the turn knob, human tissue can be easily compressed to the thickness of the reservation, and fingers and almost do not produce any friction between radial lug boss, effectively prevent the breakage of the operator by wearing latex gloves.
The anastomotic nail of digestive anastomat is composed of nail crown and nail leg in roughly U shape. The nail leg has a bending part, the upper part of the bending part is the upper part of the nail leg, and the lower part of the bending part is the lower part of the nail leg. The lower part of the nail leg bends inward at the bending part relative to the upper part of the nail leg, and the length of the nail leg is 4.84mm to 4.92mm. The height of the nail leg of the anastomosis nail can be formed normally. After forming, the nail leg bends at the bending part, which improves the probability of standard forming.
Linear cutting stapler, including handle body, push knife, nail bin seat and nail seat, handle body is provided with a push button for the control of the push knife, the handle body is connected with a CAM rotation, the CAM has a hook. The side of the CAM is provided with an insurance mechanism, when the insurance mechanism is locked, the hook part is hooked on the push button, the CAM relative handle body is fixed; When the safety mechanism is unlocked, the hook releases the push button. When the safety mechanism is locked, the CAM is fixed relative to the handle body, and the push button cannot move forward, so that the push knife can avoid being pushed prematurely when the position of the instrument is not adjusted well.
