[0027] See also Figure 1-6 As shown, the utility model is a puncture device with a suturing function, comprising a positioning structure 1, wherein the positioning platform 11 of the positioning structure 1 is formed by connecting two bosses that are wider at the top and narrower at the bottom. A positioning needle tube 12 is fixedly connected to the bottom surface of the positioning platform 11, and the bottom end of the positioning needle tube 12 is set as a sharp end. A setting hole 14 is provided in the center of the top surface of the positioning platform 11, and the setting hole 14 is set along the vertical direction, and the setting hole 14 extends downward to the bottom end of the positioning needle tube 12. Setting bevel grooves 13 are provided on both sides of the surface of the positioning needle tube 12, and the setting bevel grooves 13 are connected to the setting hole 14. The bevel grooves 13 on both sides are arranged to be tilted downward near the side of the center of the positioning needle tube 12, and the bevel grooves 13 on both sides are symmetrical about the center plane of the positioning needle tube 12. Sliding grooves 15 are provided on both sides of the top surface of the positioning platform 11, and sliding transparent plates 16 are slidably provided in the sliding grooves 15 on both sides. The upper and lower surfaces of the sliding transparent plate 16 are provided with puncture oblique holes 17, which are set in an inclined direction. The inclination angle of the puncture oblique hole 17 is the same as the inclination angle of the inclined groove 13. The top surfaces of the two sliding transparent plates 16 are fixedly connected with handles 18.

[0028] A fixed structure 2 is slidably provided in the hole 14 at the center of the positioning platform 11, and a connecting column 22 of the fixed structure 2 is slidably connected in a limited manner in the hole 14. Pressing blocks 23 are fixedly connected to both sides of the surface of the connecting column 22, and the pressing blocks 23 are tilted on the surface of the connecting column 22, and the tilt angle of the pressing blocks 23 is the same as the tilt angle of the tilt hole. A pressing disk 21 is fixedly connected to the top surface of the connecting column 22, and a convex disk 24 is fixedly connected to the top surface of the pressing disk 21. A lead structure 3 is detachably provided in the oblique puncture hole 17 of the two sliding transparent plates 16, and a puncture needle 31 of the lead structure 3 is inserted into the oblique puncture hole 17. A threading hole 32 is provided on the surface of the puncture needle 31, and a suture 4 can be inserted into the threading hole 32 of the puncture needle 31.

[0029] When using this puncture device with suturing function, the protruding convex disc 24 drives the pressing disc 21 and the connecting column 22 to move upward in the positioning platform 11, so that the setting column at the bottom is inserted into the positioning needle tube 12. The positioning needle tube 12 is then inserted under the skin for positioning. The suture 4 is then passed through the threading hole 32 of the puncture needle 31 for setting; the sliding transparent plate 16 is slid on the top surface of the positioning platform 11. When the sliding transparent plate 16 slides to the specified position, the puncture needle 31 is inserted from the puncture oblique hole 17. The puncture needle 31 passes through the skin and extends into the setting oblique groove 13 of the positioning needle tube 12. The pressing disc 21 can be pressed down so that the pressing block 23 on the surface of the connecting column 22 presses the suture 4, and then the puncture needle 31 is pulled out from the puncture oblique hole 17, so that one side of the suture 4 is fixed in the positioning needle tube 12. Similarly, the puncture needle 31 is inserted into the oblique puncture hole 17 on the other side to complete the fixation of the suture 4 on the other side. Then, the thumb presses against the pressing plate 21 to drive the pressing block 23 to press and fix the sutures 4 on both sides; the middle finger and index finger are inserted under the connecting rod to pull the positioning structure 1 and the connecting column 22 out of the skin, and at the same time, the two sutures 4 are removed from the skin to complete the subsequent suturing operation.

[0030] Among them, one end of the puncture needle 31 is fixedly connected to a contact head 33, which increases the contact area of ​​the puncture needle 31 and facilitates the removal of the puncture needle 31; the diameter of the puncture oblique hole 17 is larger than the diameter of the puncture needle 31, so that the puncture needle 31 can move in the puncture oblique hole 17 to allow the suture thread 4 to detach from the surface; the convex plate 24 arranged on the top surface of the pressing plate 21 facilitates the lifting of the pressing plate 21.

[0031] The working principle of the present invention is as follows: the present invention is a puncture device with a suturing function, which is provided with an oblique hole and a pressing block 23. The puncture needle 31 drives the suture thread 4 into the oblique groove 13, and the suture thread 4 is fixed by pressing the pressing block 23; when the puncture needle 31 is taken out, the suture thread 4 is fixed in the positioning needle tube 12, and the suture thread 4 is fixed by the fixed needle tube when it is subsequently taken out, and is directly taken out from the skin; at the same time, the pressing block 23 can prevent the connecting column 22 from being separated from the positioning platform 11, so that the connecting column 22 is slidably engaged with the positioning platform 11, so that the positioning structure 1 and the fixed structure 2 are integrated; by providing a sliding transparent plate 16, the sliding transparent plate 16 can see the insertion position of the puncture needle 31 below, and the distance between the needle and thread can be confirmed when suturing the wound to improve the suturing efficiency.
