Detailed Description
The embodiment is given by fig. 1-5, the utility model comprises a stitching instrument operating rod 1, one end of the stitching instrument operating rod 1 is provided with a fixed plate 2 and a movable plate 3, the movable plate 3 is arranged at the top of the fixed plate 2, the inner side of the movable plate 3 is fixedly provided with a needle head 4, the top end of the fixed plate 2 is fixedly provided with two metal plates 5, the inner side of the metal plates 5 is integrally formed with an arc-shaped metal clamping piece 6, one sides of the two arc-shaped metal clamping pieces 6, which are close to each other, are contacted with each other, the needle head 4 is arranged at the top between the two arc-shaped metal clamping pieces 6, the arc-shaped metal clamping piece 6 can be matched with the movable plate 3 to clamp the ligament stump so that the needle head 4 punctures the ligament stump, and simultaneously can clamp the thread head after threading so that the thread head is brought back, the threading efficiency is improved, and the form of the stub of a patient is kept as completely as possible.
The opening 7 has been seted up on fixed plate 2 top, opening 7 establishes between two metal sheets 5, just opening 7 establishes in the one side bottom of two arc metal clamping pieces 6 mutual contact, and inside needle 4 pointed end can insert opening 7 when needle 4 extrudeed between two arc metal clamping pieces 6, prevent that needle 4 pointed end from being blocked by fixed plate 2 and influencing the threading operation.
The fixed plate 2 is fixed to be equipped with conical head 8 on one side, the fly leaf 3 is established in conical head 8 one side, and when the suture instrument rifle head inserted skin incision, conical head 8 can block horizontal closed fixed plate 2 and fly leaf 3 to the joint is inserted to better, and the trafficability characteristic is better.
The metal plate 5 and the arc-shaped metal clamping piece 6 are made of stainless steel materials, and the stainless steel materials are not easy to rust.
The stapler operating rod 1 and the fixed plate 2 are fixedly connected, the movable plate 3 and the stapler operating rod 1 are movably connected through a rotating shaft, and the connecting mode and the control mode of the movable plate 3 and the stapler operating rod 1 belong to common medical instrument operation in the prior art, so that specific structures and operation details are not described too much.
Working principle:
when the suture device stretches into the skin incision, the fixed plate 2 and the movable plate 3 are close to each other and are in a horizontal closed state, at the moment, the bottom of the needle 4 is just above the gap between the two arc-shaped metal clamping pieces 6, but the needle cannot be squeezed into the middle of the two arc-shaped metal clamping pieces 6, after the fixed plate 2 and the movable plate 3 enter the joint, the movable plate 3 is unfolded, when the suture device is used for suturing the ligament residual end, the high-strength thread head is inserted into a part of the needle 4 from the tip of the needle 4, so when the tip of the needle 4 is aligned with the ligament residual end and penetrates through the ligament residual end, the needle 4 can carry the high-strength thread to pass through the ligament residual end together, and one side of the ligament residual end far away from the needle 4 in the threading process is blocked by the arc-shaped metal clamping pieces 6 on the fixed plate 2, namely, the high-strength thread is squeezed into the space between the two arc-shaped metal clamping pieces 6 after the needle 4 passes through the ligament residual end and enables the two arc-shaped metal clamping pieces 6 to be mutually far away and elastically deformed, then the movable plate 3 is controlled to be unfolded and the needle 4 is driven to withdraw from the penetrated ligament stump, along with the needle 4 being withdrawn from the middle of the two arc-shaped metal clamping pieces 6, the high-strength wire head penetrating through the ligament stump is clamped by the two arc-shaped metal clamping pieces 6, the two arc-shaped metal clamping pieces 6 are arc-shaped and have high elasticity, the lower part between the two arc-shaped metal clamping pieces 6 is narrower, when the needle 4 is withdrawn from the two arc-shaped metal clamping pieces 6, the wire head is clamped by the narrower part below the two arc-shaped metal clamping pieces 6, then the fixed plate 2 and the movable plate 3 are dragged to move by the operation rod 1 of the stitching instrument, at the moment, the high-strength wire head penetrating through the ligament stump is clamped by the two arc-shaped metal clamping pieces 6 on the fixed plate 2 and brought back to be used continuously, the operation of drawing back the high-intensity thread end by a special tool during the operation is reduced, and the control of the opening and closing of the movable plate 3 inside the stapler operation lever 1 belongs to a common medical tool technology, so that an excessive description is not made.
