Description
Technical Field
The invention belongs to the technical field of skin anastomat, and particularly relates to a nail pressing structure of a skin anastomat and the skin anastomat.
Background
The skin anastomat is suitable for suturing the superficial skin of human wounds and surgical incisions and fixing patches of abdominal hernia repair. The skin anastomat is similar to the principle of a stapler, has the advantages of simple operation, high suturing speed, good healing of a postoperative incision and the like, is a first-choice medical instrument for replacing the traditional manual superficial skin suturing in medicine, and has been widely applied to departments such as general surgery in hospitals, obstetrics, orthopaedics and the like, field rescue and the like.
The prior skin anastomat has the following defects:
(1) The staples 3 of the skin anastomat are mostly made of stainless steel wires with the diameter of 0.5-0.8mm, more commonly, the staples 3 with the diameter of 0.6 mm are used, the staples 3 are arranged in the anastomat in a plurality and are bent and formed by a staple pressing plate 1 of an internal firing mechanism, the staple pressing plate 1 presses two ends of the staples 3 through a forming surface and is matched with a staple seat 2 to realize the forming anastomosis of the staples 3 at a first position, and the formed staples 3 comprise staple beams 31, staple legs 32 positioned at two sides of the staple beams 31, staple legs 33 positioned at tail ends of the staple legs 32 and staple tips 34 positioned at tail ends of the staple legs 33. The staple pressing plate 1 is usually made of a metal sheet by punching, and the size of the forming surface is equal to the thickness of the sheet, and the size is also smaller than or equal to the diameter of the staples 3, and the staples 3 at the second position can be touched by the excessively thick staple pressing plate 1 during the firing process, so that the normal use of the stapler is affected, which is not required. When the anastomat is triggered, the axis of the anastomat 3 at the first position coincides with the central plane of the plate material of the nail pressing plate 1, the plane of the shaping surface at the end part of the nail pressing plate 1 contacts with the curved surface of the anastomat 3 in a line contact manner, when the anastomat 3 at the first position is bent and shaped to the arc shaping surface of the caliper of the nail pressing plate 1, the curved surface is in cross single point contact with the curved surface, the shaping surface of the nail pressing plate 1 is a section punched by the metal plate, the section is influenced by the stamping process and the service life of a die, and has the adverse factors of rough surface, low geometric dimension precision, inclination of the shaping surface and the like caused by the shearing and tearing belt of the section, and the anastomat touches the skin tissue skin layer with thicker or higher hardness, when the anastomat 3 is shaped, the anastomat possibly shakes or changes in position, the anastomat 3 can not be bent and shaped from the shaping surface of the nail pressing plate 1 when the bending shaping stress is maximum, and the anastomat 3 can not be bent and shaped normally;
(2) After the staples 3 are bent and formed, residual bending stress in the staples 3 causes the staple legs 32 of the staples 3 to rebound towards the reverse bending direction, when the metal blanking tearing belt is arranged on the inner molding surface of the staple pressing plate 1 to cause the surface roughness of the inner molding surface, the staples 3 are clamped on the inner molding surfaces 11 of the two calipers of the staple pressing plate 1, as shown in fig. 1, the staples are carried along with the reset and withdrawal of the staple pressing plate 1 along with the direction of an arrow, so that the nail tips 34 and the nail seat tongues 21 squeeze skin tissues to increase pain for a patient, and meanwhile, the anastomat withdraws from the formed staples 3, so that the use of the appliance is unsmooth for medical staff. In addition, the nail legs 32 after anastomosis are rebound to enlarge the distance between the formed nail tips 34, as shown in fig. 2, a larger-angle k included angle is formed, so that the anastomosis tightness of the operation wounds is different, and the wound healing effect is reduced;
(3) Because the forming surface of the nail pressing plate 1 is a punched section of a metal plate, and the cutting and tearing belt exists on the section of the forming surface, so that the forming surface of the nail pressing plate is rough, the geometric dimension precision is low, the forming surface is inclined, and other adverse factors exist, when the nail 3 is subjected to stress forming, the nail 3 rolls due to the fact that the end forming surface is inclined and is not absolutely vertically pressed down, so that the nail tip 34 deviates from the central plane of the plate of the nail pressing plate 1 and is further bent to form, namely, the nail 3 is not bent in the axis plane of the nail 3, two nail feet 33 of the nail 3 which are finally coiled into a rectangular frame shape are not lifted, and as shown in fig. 3, when the nail 3 is removed after wound healing of a patient, the lifted nail feet 33 increase the withdrawing area of the nail 3 from a wound, and the pain of the patient, and the defect should be improved.
