Alternatively, as shown in fig. 2 and 3, the outer wall surface of the outer needle 10 is provided with a limiting groove 102 penetrating through two opposite wall surfaces and extending in the axial direction, and the limiting groove 102 is communicated with the mounting hole 101. The connecting end of the inner needle 30 opposite to the protecting end 31 thereof is vertically connected with a limit pin 60, and two ends of the limit pin 60 respectively extend out of the outer needle 10 from the limit grooves 102 on the corresponding sides, so that the inner needle 30 is in limit connection with the outer needle 10. The inner needle 30 is connected with the outer needle 10 through the stopper pin 60 and is stopped, and the inner needle 30 is prevented from being ejected out of the mounting hole 101 by the elastic member 40.
Preferably, the limit groove 102 is waist-shaped, and the width of the short side of the limit groove is adapted to the outer diameter of the limit pin, so that the inner needle 30 can be guided to slide through the limit groove 102, and the stability and the puncture quality of the puncture wire hooking device in the puncture process are improved.
Preferably, the restraint slot 102 is located adjacent to the handle 20 so that the restraint pin 60 is always located outside the patient. The utility model discloses in, except that the butt effort that produces when internal tissue organ of 30 butt patients of interior needle passes through elastic component 40 and outer needle 10 feedback to the operator on hand to make the operator learn puncture crochet hook line ware puncture information that targets in place after, still because spacer pin 60 is located the patient throughout externally, thereby still directly judge through the removal of spacer pin 60 whether the puncture targets in place, judge directly perceived, reliable.
Alternatively, as shown in fig. 1 and 2, the inner needle 30 is a solid rod, which is located in the rod body of the mounting hole 101 and is contracted into a reduced diameter shaft 32 for mounting the elastic member 40, and the inner needle 30 has a simple structure and is easy to manufacture. The outer wall of the outer needle 10 surrounding the opening of the mounting hole 101 is formed as a piercing blade 104 for piercing the skin and subcutaneous layers of tissue.
Optionally, as shown in fig. 1, the wall surface of the mounting hole 101 is provided with a limiting flange 103 protruding outwards for limiting. The elastic member 40 is a spring, which is sleeved on the outer circle of the reducing shaft 32, and two ends of the spring respectively support between the step at the connecting position of the reducing shaft 32 and the protecting end 31 and the limiting flange 103. The elastic member 40 is simple to install and easy to implement.
Alternatively, the first embodiment of the wire hooking port 50, not shown, is a "C" shaped groove structure arranged along the axial direction due to the requirement of bidirectional wire hooking. When the suture hooking device is used, when the suture needs to be hooked into the skin from the outside of the skin, the suture is firstly hooked in the suture hooking port 50, when the puncture suture hooking device punctures the skin and subcutaneous tissues, the inner needle 30 retracts inwards relative to the outer needle 10, so that part of the structure of the suture hooking port 50 on the inner needle 30 drives the suture to move, is dislocated with the part of the structure of the suture hooking port 50 on the outer needle 10, and is matched with the inner wall surface of the installation pore channel 101 to clamp the suture; when the suture is required to be hooked to the outside of the skin from the inside of the skin, the suture is directly hooked in the suture hooking port 50, and when the puncture suture hooking device is withdrawn outwards, the suture is directly taken out to the outside through the suture hooking port 50. In this alternative, as shown in fig. 3, the thread hooking opening 50 includes a thread hooking hole 501 penetrating through the wall surface of the outer needle 10 and a thread hooking groove 502 recessed from the outer wall surface of the inner needle 30, and the thread hooking hole 501 and the thread hooking groove 502 are formed by synchronous processing, so that the forming quality of the thread hooking opening 50 is improved, and the processing difficulty of the thread hooking opening 50 is reduced.
Alternatively, the second embodiment of the wire hooking port 50, not shown, is a dovetail groove type structure arranged along the axial direction due to the requirement of bidirectional wire hooking; the hook string port 50 of the dovetail groove type structure functions in the same principle as the hook string port 50 of the "C" groove type structure to hook the suture string from the outside of the skin into the skin and to hook the suture string from the inside of the skin out of the skin, and the structural arrangement of the hook string port 50 of the dovetail groove type structure is the same as that of the hook string port 50 of the "C" groove type structure.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
