TECHNICAL FIELD

[0001] The utility model belongs to surgical suture fixing equipment technical field, concretely relates to a surgical suture fixing device. BACKGROUND

[0002] During operation, doctors usually need to knot and fix the suture after performing surgical suture on patients to prevent the suture from falling off. During the knotting process, the suture needs to be held by surgical forceps for knotting operation, and the suture needs to be pulled tight at the same time to avoid incomplete tissue closure, so a fixing device for fixing the surgical suture is needed to assist the knotting operation of doctors.

[0003] For example, the utility model discloses a suture fixing device in application No. CN202022601766.9, which comprises a fixing device body and a rotating handle. A containing groove penetrating in the vertical direction is arranged on the fixing device body, and the opening of the containing groove faces outward. One end of the rotating handle is rotatably installed in the fixing device body, and the other end is a free end. An active cavity for rotating the rotating handle is arranged in the fixing device body, and the active cavity is communicated with the containing groove. The end of the rotating handle located in the fixing device body is provided with a locking part, and the fixing device body is provided with a locking cavity in interference fit with the locking part. The locking cavity is communicated with the containing groove. The fixing device has simple structure and is convenient to use. The suture can be effectively locked to avoid falling off during use. In addition, the fixing device can adjust the tightness of the suture in time according to actual needs.

[0004] Although the above-mentioned application can effectively lock the suture, there are still the following technical problems in specific use: because the fixing device itself is small, and the locking part and the locking cavity are in interference fit, it is not easy to separate the locking part and the locking cavity, which causes inconvenience to medical staff. Especially during the operation of tightening the surgical suture, the locking part on the rotating handle needs to be operated, which causes inconvenience in operation. UTILITY MODEL CONTENTS

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a surgical suture fixing device, which effectively solves the problem of inconvenient operation of the existing fixing device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a surgical suture fixing device, comprising a fixing frame, a fixing cylinder fixedly connected to the fixing frame; a sliding cylinder slidably connected to the fixing cylinder is arranged on the fixing cylinder, and a compression spring matched with the sliding cylinder is arranged in the fixing cylinder; an active plate is fixedly connected to the sliding cylinder, and a fixed plate matched with the active plate is fixedly connected to the fixing frame; an active handle is fixedly connected to the active plate, and a fixed handle matched with the active handle is fixedly connected to the fixing frame.

[0007] Further, the movable plate is horizontally provided with anti-skid grooves.

[0008] Further, the fixed plate is provided with anti-skid protrusions matched with the anti-skid grooves.

[0009] Further, the movable plate is vertically provided with a plurality of anti-back teeth.

[0010] Further, the fixed plate is provided with anti-back grooves matched with the anti-back teeth.

[0011] Further, the movable plate is fixedly connected with an arc-shaped plate matched with the fixed plate.

[0012] Compared with the prior art, the operation convenience of the surgical suture fixator is improved.

[0013] In use, the sliding cylinder, the fixed cylinder and the top spring act on the movable plate to fix the suture line in cooperation with the fixed plate. BRIEF DESCRIPTION OF DRAWINGS

[0017] A surgical suture fixator, as shown in Figure 1 and Figure 2 , comprises a fixed frame 1, the fixed frame 1 is fixedly connected with a fixed cylinder 3; the fixed cylinder 3 is slidably connected with a sliding cylinder 4, and the fixed cylinder 3 is provided with a top spring 9 matched with the sliding cylinder 4; the sliding cylinder 4 is fixedly connected with a movable plate 5, and the fixed frame 1 is fixedly connected with a fixed plate 7 matched with the movable plate 5; the movable plate 5 is fixedly connected with a movable handle 6, and the fixed frame 1 is fixedly connected with a fixed handle 2 matched with the movable handle 6.

[0018] ​When the application is used, the movable plate 5 is fixed to the suture by the sliding cylinder 4, the fixed cylinder 3 and the top spring 9 in cooperation with the fixed plate 7; in addition, when the suture needs to be tightened, the movable handle 6 and the fixed handle 2 are separated to separate the movable plate 5 and the fixed plate 7, so that the suture moves upward quickly, and when the movable handle 6 is released, the suture can be fixed again, thereby improving the convenience of the application.

[0019] Further, the movable plate 5 is horizontally provided with an anti-skid groove 11, and the fixed plate 7 is provided with an anti-skid protrusion matched with the anti-skid groove 11; through the cooperation of the anti-skid groove 11 and the anti-skid protrusion, the stability of the suture fixed by the movable plate 5 and the fixed plate 7 can be effectively improved.

[0020] Further, the movable plate 5 is vertically provided with a plurality of anti-back teeth 10, and the fixed plate 7 is provided with an anti-back groove matched with the anti-back teeth 10; through the setting of the anti-back teeth 10 and the anti-back groove, the suture is prevented from being separated from the movable plate 5 and the fixed plate 7, thereby improving the stability of the suture fixed by the application.

[0021] Further, the movable plate 5 is fixedly connected with an arc-shaped plate 8 matched with the fixed plate 7; through the setting of the arc-shaped plate 8, the suture can be conveniently installed between the movable plate 5 and the fixed plate 7, thereby improving the convenience of the application.
