Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a stapler for pediatric hernia surgery. Background Art

[0002] Suturing inside the endoscope is very restricted by the operating space. The suturing process takes up most of the operation time. Usually, it takes more than ten to twenty minutes to suture one stitch, which not only requires high skills for doctors, but also brings certain potential risks to wound infection and the like.

[0003] In order to simplify the complicated process and difficulty of the suturing steps, staplers have emerged. However, traditional staplers cannot be operated inside the endoscope. Some staplers that can be operated inside the endoscope are restricted by their operation and holding parts. When suturing, they are likely to block the entrance of the endoscope and cannot simultaneously insert other tools such as forceps into the endoscope, and it is not conducive to observation, which further increases the operation difficulty and requires extremely high skills for doctors. Therefore, staplers for suturing under the endoscope have emerged.

[0004] For the existing stapler for pediatric hernia surgery, for high ligation of the pediatric hernia sac under laparoscopy, one stapler is for thread feeding and the other is for thread pulling. Two groups of staplers need to be operated simultaneously. When the two groups of staplers are operated simultaneously, the distance between them is relatively close, and there are limitations in use.

[0005] In view of this, a stapler for pediatric hernia surgery is proposed to solve the above problems. Content of the Utility Model

[0006] I. Technical Problems to be Solved

[0007] The technical problem to be solved by the utility model is that for high ligation of the pediatric hernia sac, one stapler is for thread feeding and the other is for thread pulling. When the two groups of staplers are operated simultaneously, the distance between them is relatively close, and there are limitations in use.

[0008] II. Technical Solution

[0009] To solve the above technical problems, the technical solution provided by the utility model is: a stapler for pediatric hernia surgery, including a needle forceps tube. A traction rod is slidably arranged inside the needle forceps tube. One end of the needle forceps tube is provided with a sleeve. One end of the traction rod is slidably inserted into the sleeve and connected with a push rod. The other end of the push rod slides out of the sleeve and is connected with a pressing block. Two groups of support blocks are installed on the outer side of the sleeve. One end of the traction rod located inside the needle forceps tube is provided with a grasping mechanism;

[0010] The grasping mechanism includes a connecting rod. L-shaped grasping forceps are respectively hinged on the opposite sides of the connecting rod. Grooves are respectively arranged in the middle of the two side walls of the connecting rod connected with the L-shaped grasping forceps. A second spring is connected between the bottom of the groove and the L-shaped grasping forceps.

[0011] As an improvement, a threaded connecting rod is installed at one end of the connecting rod, and a threaded hole for inserting the threaded connecting rod is provided at one end of the traction rod located inside the needle forceps tube.

[0012] As an improvement, the cross-section of the connecting rod is of a square structure, the inner wall of the needle forceps tube is of a rectangular structure, and the opposite two sides of the connecting rod are in contact with the inner wall of the needle forceps tube while the other two side walls are not in contact with the inner wall of the needle forceps tube.

[0013] As an improvement, the length of the side wall of the L-shaped forceps away from the connecting rod is less than the distance between the two side walls of the connecting rod.

[0014] As an improvement, the edges of the two groups of L-shaped forceps away from the connecting rod are cut surfaces.

[0015] As an improvement, the two cut surfaces are offset, and the side walls of the two groups of L-shaped forceps away from the connecting rod are in contact.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] As shown in the attached Figure 1 、 attached Figure 2 and attached Figure 3 As shown, a stapler for pediatric hernia surgery includes a needle forceps tube 1. A traction rod 3 is slidably arranged inside the needle forceps tube 1. One end of the needle forceps tube 1 is provided with a sleeve 2. One end of the traction rod 3 is slidably inserted into the sleeve 2 and connected with a push rod 4. The other end of the push rod 4 slidably passes through the sleeve 2 and is connected with a pressing block 7. Two groups of support blocks 8 are installed on the outer side of the sleeve 2. One end of the traction rod 3 located inside the needle forceps tube 1 is provided with a grasping forceps mechanism 9;

[0027] The grasping forceps mechanism 9 includes a connecting rod 901. L-shaped grasping forceps 902 are respectively hinged on the opposite sides of the connecting rod 901. Grooves 903 are respectively arranged in the middle parts of the two side walls of the connecting rod 901 connected with the L-shaped grasping forceps 902. A second spring 904 is connected between the bottom of the groove 903 and the L-shaped grasping forceps 902.

[0028] With the above structure, during suturing, the index finger and middle finger are placed on one side of the two groups of support blocks 8, and the thumb pushes the pressing block 7. By pushing the pressing block 7, the push rod 4 and the traction rod 3 are moved. Through the traction rod 3, the grasping mechanism 9 is pushed out of the needle forceps tube 1. The two groups of L-shaped grasping claws 902 are pushed by the second spring 904 and move away from the connecting rod 901. The two groups of L-shaped grasping claws 902 move apart. The suture is placed between the two groups of L-shaped grasping claws 902. Pull the pressing block 7 in the reverse direction, pull the grasping mechanism 9 into the needle forceps tube 1, squeeze the L-shaped grasping claws 902, drive the suture to retract into the needle forceps tube 1, pass the needle forceps tube 1 through the subcutaneous edge into the abdominal cavity. As described above, push the grasping mechanism and the suture out of the needle forceps tube 1, the two groups of L-shaped grasping claws unfold, and place the suture inside the abdominal cavity. Also as described above, retract the grasping mechanism 9 into the needle forceps tube 1, pull out the needle forceps tube 1 from the child's skin tissue, pass the needle forceps tube 1 through the subcutaneous edge on the other side into the abdominal cavity. In the same way, place the suture between the two groups of L-shaped grasping claws, then retract the grasping mechanism 9 into the needle forceps tube 1, drive the needle forceps tube 1 to draw out the suture, and tie and suture the suture. The specific structure is as follows:

[0029] Combined with the attached Figure 2 and the attached Figure 3 As shown, the cross-section of the connecting rod 901 is a square structure, the inner wall of the needle forceps tube 1 is a rectangular structure. The two opposite sides of the connecting rod 901 are in contact with the inner wall of the needle forceps tube 1, and the other two side walls are not in contact with the inner wall of the needle forceps tube 1. The length of the side wall of the L-shaped grasping claw 902 away from the connecting rod 901 is less than the distance between the two side walls of the connecting rod 901.

[0030] With the above structure, the two opposite sides of the connecting rod 901 are in contact with the inner wall of the needle forceps tube 1, enabling the connecting rod 901 to slide and be limited inside the needle forceps tube 1. The other two side walls are not in contact with the inner wall of the needle forceps tube 1, providing a storage space when the L-shaped grasping claws 902 are retracted into the needle forceps tube 1.

[0031] Combined with the attached Figure 3 As shown, the edges of the two groups of L-shaped grasping claws 902 away from the connecting rod 901 are cutting surfaces 905. The two groups of cutting surfaces 905 are offset, and the side walls of the two groups of L-shaped grasping claws 902 away from the connecting rod 901 are in contact.

[0032] With the above structure, when the two groups of L-shaped grasping claws 902 approach each other on the side away from the connecting rod 901, the edges of the L-shaped grasping claws 902 are of the cutting surface 905 structure, which will not affect the wrong connection and overlap of the two groups of L-shaped grasping claws 902, enabling the sides of the two groups of L-shaped grasping claws 902 away from the connecting rod 901 to fit together and preventing the suture from detaching between the two groups of L-shaped grasping claws 902.

[0033] Combined with the attached Figure 2As shown, a push plate 5 is installed between the towing rod 3 and the push rod 4. A first spring 6 is connected between the push plate 5 and the side wall of the sleeve 2 away from the needle forceps tube 1, and the first spring 6 is sleeved outside the push rod 4.

[0034] With the above structure, the first spring 6 can drive the push plate 5 to automatically return to its original position, and there is no need to pull the pressing block 7 again to drive the push plate 5 to return to its original position.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, please refer to the attached Figure 3 and the attached Figure 4 , one end of the connecting rod 901 is installed with a threaded connecting rod 10, and a threaded hole 11 for the threaded connecting rod 10 to insert is provided at one end of the towing rod 3 inside the needle forceps tube 1.

[0037] With the above structure of Embodiment 2, the connecting rod 901 can be connected to the towing rod 3 by inserting the threaded connecting rod 10 into the threaded hole 11, which is convenient for disassembling and replacing the grasping mechanism 9.
