[0001] The utility model belongs to the technical field of medical equipment, in particular to a blood vessel suturing device. Background Art

[0002] The vascular suture device is composed of a suture device and a suture trimmer. The existing suture device includes two stainless steel needles and sutures. The suture material is polypropylene, the specification is 3-0, and it is disposable. This product is suitable for patients who use 5F to 8F (about 1.67~2.67mm) sheaths for interventional catheter examination or treatment. After the operation, the suture is delivered percutaneously to suture the common femoral artery puncture point. When the needle at the front end of the vascular suture device is inserted into the blood vessel under the patient's skin, since the suture operation is required, one hand needs to use the adjustment handle on the suture device and the other hand needs to hold the suture device, which will cause shaking to affect the accuracy of the suture position and also cause discomfort to the patient.

[0022] When the second driving button 16 is pushed to drive the pneumatic piston rod 13 to move up and down, the inner cavity gas at the top of the active air cavity 12 can be discharged through the air inlet and exhaust grooves 14 and the one-way ventilation valve flap 15, or the external gas can be introduced into the inner cavity of the active air cavity 12 through the one-way ventilation valve flap 15 and the air inlet and exhaust grooves 14, so that the bottom of the pneumatic piston rod 13 can stably generate negative pressure to suck and fix it or blow to release the fixation operation.

[0023] like Figures 1 to 3 As shown, the bottom end of the fitted support frame 17 is made of rubber, and medical adhesive films 18 are provided at the front and rear sides of the bottom end of the fitted support frame 17 .

[0024] By adopting the above scheme, through the corresponding deformability of the bottom end of the fitting support frame 17, it can be adaptively fitted and fixed according to the skin surface of different patients and different limb positions, and the two medical adhesive films 18 can contact the skin after fitting and adsorbing and fixing, thereby improving the overall grip of the fitting support frame 17, making it more firm and stable.

[0025] like Figure 2 and Figure 6 As shown, the rear end of the second driving plate 16 extends to the back side of the fitted support frame 17 , and the surface of the second driving plate 16 is movably connected to the inner wall of the fitted support frame 17 .

[0026] By adopting the above scheme, a second driving plate 16 is provided. When the medical staff pushes the second driving plate 16 to drive the movable air cavity 12 to move, the second driving plate 16 and the inner wall of the fitting support frame 17 can smoothly move vertically up and down under the limiting sliding action.

[0027] like Figure 1 middle Figure 3 As shown, an adjusting screw 3 is threadedly sleeved in the middle of the left side of the inner wall of the slidable sleeve 2 .

[0028] By adopting the above scheme, an adjusting screw 3 is provided. When the medical staff rotates the adjusting screw 3 to move it to the left or right position, the right end of the adjusting screw 3 can be separated from or fitted with the vascular suture device body 1, thereby achieving the loosening and fixing of the slidable sleeve 2 on the inner wall of the vascular suture device body 1.

[0029] like Figure 2 and Figure 5 As shown, the inner wall of the top of the fitting support frame 17 is fixedly sleeved with the mounting sleeve shaft 5 inside the mounting support seat 4, the surface of the mounting sleeve shaft 5 is movably sleeved with the inner wall of the mounting support seat 4 and the right end surface is fixedly sleeved with the locking gear 6, the right side of the slidable sleeve 2 is fixedly installed on the rectangular mounting sleeve shell 7 above the locking gear 6, and the inner wall of the rectangular mounting sleeve shell 7 is movably installed with a locking tooth block 8; the bottom end of the locking tooth block 8 is meshed with the surface of the locking gear 6.

[0030] By adopting the above scheme, a locking tooth block 8 is provided. When the bottom end of the locking tooth block 8 is downwardly fitted with the surface of the locking gear 6, the locking gear 6, the mounting sleeve shaft 5 and the fitting support frame 17 can be fixed to the bottom of the slidable sleeve 2.

[0031] like Figure 5 As shown, a locking spring 9 located between the inner walls of the rectangular mounting sleeve 7 is fixedly installed on the top of the locking tooth block 8, and a first driving plate 10 is fixedly installed on the top of the right side of the locking tooth block 8, and the right side of the first driving plate 10 extends to the right side of the rectangular mounting sleeve 7.

[0032] By adopting the above scheme, a locking spring 9 is provided. When the medical staff pushes the first driving plate 10 to drive the locking tooth block 8 upward, the bottom of the locking tooth block 8 can be separated from the locking gear 6, and at the same time the locking spring 9 will be compressed, and then the first driving plate 10 is released. At this time, the elastic force of the locking spring 9 will be restored and push the locking tooth block 8 as a whole downward to fit and clamp with the locking gear 6.

[0033] The working principle and use process of this utility model:

[0034] First, the medical staff can first fit the fixed adsorption plate 11 at the bottom of the fitting support frame 17 to the skin surface of the blood vessel to be sutured, and through the deformability of the bottom of the fitting support frame 17, it can be adapted and fitted therewith, and then push the second driving button 16 to drive the pneumatic piston rod 13 upward, so that the bottom cavity of the fitting support frame 17 and the fixed adsorption plate 11 generate negative pressure, so that the fixed adsorption plate 11 and the human skin are completely in contact with each other to achieve support and fixation. At the same time, the two medical adhesive films 18 at the bottom of the fitting support frame 17 will also contact the patient's skin, thereby increasing the overall grip of the fitting support frame 17 and the fixed adsorption plate 11 and improving the fixation effect.

[0035] Then, when it is necessary to adjust to forty-five degrees for needle insertion, the first driving plate 10 can be pushed to drive the locking tooth block 8 upward to release the fixing effect on the locking gear 6, the mounting sleeve shaft 5 and the fitted support frame 17 as a whole, and then the vascular suture device body 1 and the slidable sleeve frame 2 as a whole are smoothly adjusted to a forty-five degree tilt, and then the first driving plate 10 is released, so that the locking spring 9 pushes the locking tooth block 8 downward to engage and clamp the locking gear 6, and the vascular suture device body 1 and the slidable sleeve frame 2 are fixed as a whole above the fitted support frame 17. Finally, when inserting the needle, the adjusting screw 3 can be rotated first to release the fixing effect of the vascular suture device body 1 inside the slidable sleeve frame 2, and the subsequent needle insertion and vascular suture operation can be carried out.
