The specific meaning of the above terms in this application will be understood to be a specific case for those of ordinary skill in the art.

As shown in fig. 1, the utility model provides a laparoscope incision stitching instrument, which comprises a stitching frame and a thread-drawing needle, the sewing frame comprises a frame body 1, a base 2, a fixed arm 3 and a movable arm 4, wherein the frame body 1 is vertically connected with the fixed arm 3, the movable arm 4 and the base 2 from top to bottom in sequence, the top of the frame body 1 is also provided with a handle, the movable arm 4 is connected with the frame body 1 in a sliding way, the fixed arm 3 is provided with a first needle hole 5, the movable arm 4 is provided with a second needle passage hole 6, the base 2 is provided with a needle falling groove 7, the first needle passage hole 5, the second needle passage hole 6 and the needle falling groove 7 are coaxially arranged to jointly form a thread pulling needle channel, the axis of the channel is parallel to the frame body 1, the thread pulling needle is inserted into the thread pulling channel from top to bottom, a thread inlet groove 8 is formed in the bottom of the frame body 1, and the thread inlet groove 8 penetrates through the base 2 and penetrates through the needle falling groove 7. Due to the double arrangement of the movable arm 4 and the fixed arm 3, the yarn pulling needle is guaranteed not to move, and the needle falling precision is improved. The wire inlet groove 8 is V-shaped, so that a suture can be placed conveniently.

4 one end of digging arm and 1 muffjoint of support body, it is fixed through bolt 9, and digging arm 4 can be adjusted from top to bottom according to abdominal wall tissue thickness, the one end that digging arm 4 kept away from support body 1 sets up support arm 10, and when carrying out subcutaneous suture, support arm 10 can withstand skin, struts the skin after, is convenient for subcutaneous full-thickness suture.

In order to meet the use requirements of different patients, a second suture guide channel is arranged on the fixed arm 3, the movable arm 4 and the base 2. The distance between the first suture traction needle channel and the frame body is about 0.6-0.8cm, and the suture traction needle is suitable for fat patients; the second thread-drawing needle channel is about 0.3-0.5cm away from the frame body, which is suitable for the people with relatively thin body.

In order to make the suture line 11 tense and not shift, two sides of the bottom of the base 2 are provided with line pressing devices, as shown in fig. 3, each line pressing device comprises a movable line pressing block 16 and a line pressing column 19, the top of the line pressing column 19 is fixed at the top of the base 2, the line pressing column 19 is sleeved with a spring 12, one end of the spring 12 is fixedly connected with the base 2, the other end of the spring is connected with the movable line pressing block 16 which is arranged on the line pressing column 19 in a connecting mode, and the movable line pressing block 16 can slide on the line pressing column 19 along with the spring 12. The suture 11 passes through the thread inlet groove 8, the movable thread pressing block 16 slides to fix the suture 11 between the movable thread pressing block 16 and the base 2, and the suture 11 is in a tightening state and passes through the upper part of the needle falling groove 7.

A thread pressing device can also be arranged between the two needle falling grooves 7.

The bottom of the movable wire pressing block 16 is provided with a metal elastic sheet, and the metal elastic sheet can make a sound when colliding. When the wire pulling needle hooks out the suture line 11, the metal elastic sheet collides with the base 2 to make a sound, so as to prompt an operator to hook the suture line successfully.

As shown in figure 2, a line hooking groove 14 is arranged at the needle point 13 of the line drawing needle, the notch of the line hooking groove 14 is positioned on the side wall of the needle body 15, and the groove depth is inclined to the needle point 13. So that the suture 11 can easily enter the suture channel 14 when the pull pin is dropped.

The cross section of the thread inlet groove 8 is V-shaped, and the distance between the bottom of the needle falling groove 7 and the bottom of the thread inlet groove 8 is larger than the distance between the needle point 13 of the thread pulling needle and the thread hooking groove 14, so that after the thread pulling needle falls into the needle falling groove 7, the thread hooking groove 14 can be lower than the suture thread 11, and thread hooking is facilitated.

The side wall of the wire pulling needle body 15 is provided with scale marks 18, and the wire hooking groove 14 is located on the right side of the scale marks 18. The depth of insertion of the suture pulling needle can be known according to the scale marks 18, so that the thickness of the abdominal wall can be measured, and meanwhile, the suture hooking groove 14 is determined to be lower than the suture 11.

As shown in fig. 4, due to the operation in the abdominal cavity, the view is easily blocked by hand, a marking line 17 perpendicular to the axis of the fixing arm 3 is arranged at the position of the fixing arm 3 close to the first needle hole 5, the thread pulling needle is rotated to enable a scale line 18 on a needle handle 16 of the thread pulling needle to be parallel or tangent to the marking line 17 on the fixing arm 3, and at the moment, the thread hooking groove 14 is vertically opposite to the suture thread, so that the operation is convenient. The traction needle is also provided with a needle handle, so that the traction needle is convenient to hold by hand.

Because the puncture macropore of peritoneoscope is about 1.0 ~ 1.2cm, the base 2 of suturing device need be put into abdominal cavity wall peritoneum membrane, so base 2 design length is 0.9cm, and support body 1 is tiny simultaneously to easily put into under the puncture hole. Whereas the puncture hole (less chance of suturing) of the laparoscope is about 0.5cm, the stapler can be designed to a corresponding size.

The utility model discloses a use method:

putting a suture line 11 into the line-feeding groove 8, pressing the suture line 11 by line pressing devices on two sides of the base 2 to enable the suture line to have a little tension, inserting the base 2 into the bottom of an incision, vertically lifting the incision after adjustment, if a lifting sense indicates that the suture line has penetrated into the bottommost part of the incision, if the lifting sense does not exist, continuing adjustment, adjusting the movable arm 4 after the lifting state exists, enabling the supporting arm 10 to push open the skin, exposing subcutaneous tissues, fixing the suture line well by a bolt 9, and enabling a thread-pulling needle to pass through a corresponding thread-pulling needle channel to reach a needle-dropping groove 7 of the base 2; the needle handle 16 is rotated to enable the scale marks 18 to be parallel to the marking lines 17 on the fixed arm 3, the scale marks are lifted upwards to hook the suture lines 11, when the suture lines 11 fall off from the line pressing device, the metal elastic sheet at the bottom of the movable line pressing block 16 collides with the base 2 to make a sound to prompt an operator to hook the suture lines successfully, the suture lines are pulled out at the moment, one side of the cut is sewn, the other side is sewn by the same method, and the sewing is finished by conventional knotting.

Of course, the present invention may have other embodiments, and those skilled in the art may make various corresponding changes and modifications according to the present invention without departing from the spirit and the essence of the present invention, and these corresponding changes and modifications should fall within the protection scope of the appended claims.
