Furthermore, the bottom end of the movable handle 12 is provided with a clamping groove 122, and when the pin 125 is toggled outwards to separate the movable handle 12 from the fixed handle 111, and the movable handle 12 is rotated to make the movable handle 12 and the fixed handle 111 form an included angle of 90 degrees, the movable handle 12 is pressed downwards to make the movable handle 12 be clamped at the top of the fixed handle 111 through the clamping groove 122.

In addition, the clamping head 14 includes an end block 141 having a cylindrical structure, a fixing plate 142 fixed to a bottom end of the end block 141, and a clamping rod 143 fixed to a bottom end of the fixing plate 142, wherein a hanging block 1411 is disposed at a top end of the end block 141, the hanging block 1411 is inserted into the hanging groove 131, a distal end of the clamping rod 143 is in a state of being away from the fixing plate 142 without an external force, and the clamping rod 143 is pressed by an inner wall of the limiting chamber 113 when being retracted into the limiting chamber 113, so that the distal end of the clamping rod 143 is close to the distal end of the fixing plate 142.

It should be noted that when the bottom end of the movable handle 12 is aligned with the top end of the fixed handle 111, after the push plate 132 is pushed downward to make the push plate 132 abut against the top end of the movable handle 12, the return spring 1211 is in a compressed state, and the end block 141 moves downward along the limiting cavity 113 to the cavity of the limiting cavity 113, and the bottom end of the fixed plate 142 is away from the bottom end of the clamping rod 143, so that the clamping head 14 is in an open state at this time, so that the fixed plate 142 and the clamping rod 143 clamp the suture thread in the human body, when the push rod 13 drives the clamping head 14 to retract into the limiting cavity 113 by loosening the push plate 132, the clamping rod 143 is squeezed and clamps the suture thread on the fixed plate 142, and the clamping head 14 retracts into the limiting cavity 113, so that the suture thread is clamped to the bottom end of the needle rod 11, and at this time, the medical staff pulls out the suture needle 1 to make the needle rod 11 drive the suture thread to pull out the suture thread, so as to suture the wound.

It is worth explaining that, after the movable handle 12 is rotated to make the movable handle 12 and the fixed handle 111 form an included angle of 90 degrees, the movable handle 12 is pressed downwards to enable the clamping groove 122 to be clamped at the top of the fixed handle 111, at this time, the push plate 132 is pressed downwards to enable the push plate 132 to completely push the clamping head 14 outwards from the limiting cavity 113 through the push rod 13, the medical staff can make the hanging block 1411 deviate from the hanging groove 131 by poking the clamping head 14, so as to achieve the purpose of disassembling the clamping head 14, so as to replace the clamping head 14, so that the clamping head 14 only needs to be replaced for the clamping head 14 after being damaged, the whole suture needle 1 does not need to be replaced, and the maintenance cost of the suture needle 1 is reduced. Meanwhile, the movable handle 12, the push rod 13 and the clamping head 14 on the suture needle 1 can be detached, so that the disinfection solution can fully wash the suture needle 1 and prevent dirt from remaining in the needle rod 11 when the suture needle 1 is disinfected and cleaned before and after an operation.

In the above scheme, the bottom of the suture needle 1 is provided with the stopper 2, the stopper 2 comprises a sleeve column 21, a support column 22 sleeved in the sleeve column 21 and an abutting spring 23 abutting against the tail end of the support column 22, and the sleeve column 21 and the support column 22 are sequentially penetrated through by the needle rod 11. The head end of the sleeve column 21 is provided with a sleeve cavity 211, the outer surface of the sleeve column 21 is provided with a through groove 212, the abutting spring 23 is located at the bottom of the sleeve cavity 211, the abutting column 22 is in sliding connection with the sleeve column 21, the outer peripheral surface of the abutting column 22 is provided with a abutting groove 221, the needle rod 11 penetrates through the through groove 212 and the abutting groove 221, the through groove 212 and the abutting groove 221 are both longer than the outer diameter of the needle rod 11, under the elastic force action of the abutting spring 23, the abutting column 22 is pushed outwards by the abutting spring 23, the needle rod 11 can be clamped between the sleeve column 21 and the abutting column 22, the purpose of fixing the position of the position limiter 2 on the needle rod 11 is achieved, the position limiter 2 can limit the length of the bottom end of the needle rod 11 inserted into the patient, and the situation that the tip of the needle rod 11 stabs the tissues in the patient due to the overlong length of the needle rod 11 inserted into the patient is prevented. When medical personnel pressed support post 22, support post 22 can follow set cavity 211 inward movement, can make needle bar 11 lose set post 21 and support post 22's centre gripping when making support post 22 compression butt spring 23 to make stopper 2 can follow the surface of needle bar 11 and carry out the removal of upper and lower direction, can conveniently adjust in order to the position to stopper 2, so that needle bar 11 can be adjusted the length of inserting human inside.

The working principle of the multifunctional endoscopic needle-shaped stitching instrument is as follows:

firstly, when a suture is clamped, the bottom end of the needle rod 11 is inserted into a patient body, the push plate 132 is pushed to enable the push plate 132 to downwards push the push rod 13, the push rod 13 drives the clamping head 14 downwards to move outwards, the fixing plate 142 and the clamping rod 143 are enabled to outwards extend out of the limiting cavity 113, at this time, under the elastic action of the clamping rod 143, the bottom end of the clamping rod 143 is far away from the fixing plate 142, the clamping head 14 is enabled to be opened and clamped on the outer side of the suture, then, the push rod 13 can drive the clamping head 14 to retract into the limiting cavity 113 under the elastic action of the return spring 1211 by loosening the push plate 132, the clamping rod 143 is squeezed and clamps the suture on the fixing plate 142, the suture can be clamped to the bottom end of the needle rod 11, at this time, medical personnel can outwards pull out the suture needle 1 to enable the needle rod 11 to outwards so as to suture wounds;

then when the suture needle 1 needs to be cleaned and disinfected or the clamping head 14 needs to be replaced, the pin 125 at the two sides of the movable handle 12 is simultaneously pulled outwards to enable the tail end of the pin 125 to be far away from the fixed handle 111, so that the movable handle 12 can be detached from the fixed handle 111, at the moment, the movable handle 12 is rotated 90 degrees above the fixed handle 111, then the movable handle 12 is pressed downwards, the movable handle 12 is clamped at the top of the fixed handle 111 through the clamping groove 122, at the moment, the clamping head 14 can be completely pushed out from the limiting cavity 113 through the push rod 13 by pressing the push plate 132 downwards, the hanging block 1411 can be pulled out from the hanging groove 131 by the medical staff by pulling the clamping head 14, the purpose of detaching the clamping head 14 is achieved, the clamping head 14 is convenient to replace, and the suture needle 1 can be detached and cleaned by detaching the movable handle 12 from the fixed handle 111 and pulling the push rod 13 out of the needle rod 11;

finally, when the suture needle 1 is used for suture of wounds, the support pillar 22 can be pressed downwards to enable the support pillar 22 to move inwards along the sleeve cavity 211, at the moment, the support pillar 22 compresses the abutting spring 23 and simultaneously enables the needle rod 11 to lose the clamping of the sleeve pillar 21 and the support pillar 22, so that the limiting stopper 2 can move vertically along the outer surface of the needle rod 11, the position of the limiting stopper 2 can be conveniently adjusted, the needle rod 11 can adjust the length inserted into the human body, and the situation that the tip of the needle rod 11 stabs the tissues in the body of a patient due to the fact that the needle rod 11 inserted into the body of the patient is too long can be prevented.
