[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. In the present invention, a suture needle clamping device is provided. When it is necessary to suture the patient's wound, the two disinfected slide plates are first slid into the arc grooves of the first clamping member and the second clamping member respectively, and the screw rod is rotated at this time. The screw rod fixes the two slide plates on the surfaces of the first clamping member and the second clamping member respectively by means of the thread, and then the two holding drive rods are pulled. At this time, the two holding drive rods respectively drive the first clamping member and the second clamping member to rotate, and then the first clamping member and the second clamping member are moved to the position of the needle, and then the first clamping member and the second clamping member clamp the arc surface of the needle, and make the end of the needle with the suture thread contact with the surfaces of the two baffles, at this time, the two clamping plates on the two slide plates will be respectively clamped by the elastic force of the first spring, and the anti-skid pad on the side of the two clamping plates close to each other is in contact with the arc surface of the needle, and the anti-skid pad on the surface of the clamping plate serves to increase the space between the needle and the clamping plate. The effect of friction is achieved to prevent the needle from sliding between the two clamping plates when the first clamping member and the second clamping member move with the needle clamped. The limit rod limits the direction of the elastic force of the first spring and thus limits the moving position of the clamping plate. Then the first clamping member and the second clamping member are moved to make the clamping plate drive the needle to penetrate into the skin of the patient's wound. The baffle helps push the needle to penetrate the skin better. After the needle passes through the skin, the first clamping member and the second clamping member are flipped 180 degrees. Then the clamping plate clamps the needle and pulls the needle out from the other end of the skin, thereby achieving the effect of assisting the needle in suturing the wound. The rubber pad further fixes the needle, solving the problem that the clamping force of the traditional needle threading clip on the needle is limited. When the needle is clamped to assist in suturing the wound, the needle is easy to slide with the needle threading clip, thereby reducing the work efficiency of suturing the patient's wound.

[0016] 2. In the present invention, by setting a cutting device, when the wound is sutured and the suture thread of the needle needs to be cut, the slider on the sterilized blade is first aligned with the movable plate, and then the slider is slid into the slide groove of the movable plate. The slider and the slide groove play the effect of facilitating the installation and removal of the blade, and then the hook is pulled out from the buckle of the baffle plate. At this time, the second spring will give a pulling force to the connecting plate to make the connecting plate drive the movable plate to move, and the movable plate drives the blade to move. The tips of the two blades will contact the surface of the suture thread of the needle. The two blades will cut the suture thread of the needle at this time, achieving the effect of cutting the excess suture thread at the end of suturing. After the cutting is completed, the hook is pulled and hung on the buckle, and the connecting cloth will fix the position of the connecting plate. At this time, the position of the movable plate is fixed, and the position of the blade is also fixed, thereby achieving the effect of fixing the position of the connecting plate, and then achieving the effect of facilitating the cutting of the suture thread next time, solving the problem that the traditional needle and thread clip can only assist in needle threading, and after the needle threading is completed, the suture thread needs to be cut with scissors, which reduces the efficiency of wound suturing.

[0017] 3. In the present invention, by setting a limit device, when the needle and thread clip is used, the latch is pulled first to draw the latch out of the clamping hole of the handle, and then the handle is rotated. At this time, the handle drives the rotating shaft to rotate, and the rotating shaft begins to wrap the elastic cloth. The length of the elastic cloth will decrease accordingly, and the elastic cloth will pull the first clamping plate to move in the direction close to the second clamping plate. The first clamping plate and the second clamping plate will fix the two holding drive rods in the middle, thereby achieving the effect of fixing the positions of the first clamping member and the second clamping member. Then the latch is re-inserted into the clamping hole of the handle, thereby achieving the effect of fixing the position of the handle and then fixing the position of the rotating shaft. This solves the problem that when a doctor carries a medicine box with needle and thread clips for surgery, the needle and thread clips are easily opened when they are bumped, and the opened needle and thread clips are easy to mess up other medicines.

[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0029] Embodiment 1, as Figure 1-8 As shown, the present invention provides an anti-loosening needle clamp for surgical suturing, comprising a first clamping member 1 and a suture needle clamping device 4, the surface of the first clamping member 1 is rotatably connected to the second clamping member 2, the lower surfaces of the first clamping member 1 and the second clamping member 2 are fixedly connected to a holding drive rod 3, and the surfaces of the first clamping member 1 and the second clamping member 2 are provided with a suture needle clamping device 4.

[0030] The specific arrangement and functions of the suture needle clamping device 4, the cutting device 5 and the limiting device 6 are described in detail below.

[0031] like Figure 3 and Figure 4As shown, the suture needle clamping device 4 includes two arc grooves 401, and the two arc grooves 401 are respectively opened on the surfaces of the first clamping member 1 and the second clamping member 2. The inner wall of the arc groove 401 is slidably connected with a slide plate 402, and the side of the slide plate 402 away from the arc groove 401 is evenly fixedly connected with two first springs 403. First, the two sterilized slide plates 402 are respectively slid into the arc grooves 401 of the first clamping member 1 and the second clamping member 2, and then the screw rod 406 is rotated. The screw rod 406 fixes the two slide plates 402 on the surfaces of the first clamping member 1 and the second clamping member 2 respectively by means of the thread, and then the holding drive rod is pulled. 3, at this time, the driving rod 3 is held to drive the first clamping member 1 and the second clamping member 2 to rotate, so that the first clamping member 1 and the second clamping member 2 clamp the arc surface of the needle, and the end of the first spring 403 away from the slide plate 402 is fixedly connected to the clamping plate 404, and the end of the slide plate 402 away from the first clamping member 1 is fixedly connected to the support plate 405, and the middle part of the support plate 405 is threadedly connected with a screw 406, and the ends of the two screws 406 away from the support plate 405 are respectively clamped with the first clamping member 1 and the second clamping member 2, and the first clamping member 1 and the second clamping member 2 are fixedly connected to the side away from the support plate 405. The baffle plate 407 is fixedly connected to the baffle plate 407. 7 is in an "L" shape, and the two slide plates 402 are fixedly connected with a rubber pad 408 on one side close to each other, and the baffle plate 407 plays an effect of assisting the needle to better penetrate the skin. After the needle passes through the skin, the first clamping member 1 and the second clamping member 2 are turned 180 degrees, and then the clamping plate 404 clamps the needle. The anti-skid pad 409 on the surface of the clamping plate 404 increases the friction between the needle and the clamping plate 404. The limit rod 410 limits the direction of the elastic force of the first spring 403 and thus limits the moving position of the clamping plate 404. Then the first clamping member 1 and the second clamping member 2 are moved to allow the clamping plate 404 to carry The movable needle is inserted into the skin of the patient's wound, and the needle is pulled out from the other end of the skin, thereby achieving the effect of assisting the needle in suturing the wound. The rubber pad 408 further fixes the needle. The two rubber pads 408 are in an arc shape on the side close to each other. The side of the clamping plate 404 away from the first spring 403 is fixedly connected with an anti-slip pad 409. The size of the anti-slip pad 409 is adapted to the size of the clamping plate 404. The internal sliding connection of the first spring 403 is connected with a limit rod 410. One end of the limit rod 410 is fixedly connected to the slide plate 402, and the end of the limit rod 410 away from the slide plate 402 is slidably connected to the clamping plate 404.

[0032] The effect achieved by the entire suture needle clamping device 4 is that, by setting the suture needle clamping device 4, when it is necessary to suture the patient's wound, the two disinfected slide plates 402 are first slid into the arc grooves 401 of the first clamping member 1 and the second clamping member 2 respectively, and then the screw rod 406 is rotated, and the screw rod 406 fixes the two slide plates 402 on the surfaces of the first clamping member 1 and the second clamping member 2 respectively by means of the thread, and then the two gripping drive rods 3 are pulled, and at this time, the two gripping drive rods 3 drive the first clamping member 1 and the second clamping member 2 respectively. The first clamping member 1 and the second clamping member 2 rotate, and then the first clamping member 1 and the second clamping member 2 move to the position of the needle, and then the first clamping member 1 and the second clamping member 2 clamp the arc surface of the needle, and make the end of the needle with the suture thread contact the surface of the two baffles 407. At this time, the two clamping plates 404 on the two slides 402 will be respectively subjected to the elastic force of the first spring 403 to clamp the needle. At this time, the anti-skid pad 409 on the side where the two clamping plates 404 are close to each other is in contact with the arc surface of the needle, and the anti-skid pad on the surface of the clamping plate 404 409 increases the friction between the needle and the clamping plate 404, thereby preventing the needle from sliding against the two clamping plates 404 when the first clamping member 1 and the second clamping member 2 are moved while clamping the needle. The limiting rod 410 limits the direction of the elastic force of the first spring 403 and thus limits the moving position of the clamping plate 404. Then the first clamping member 1 and the second clamping member 2 are moved so that the clamping plate 404 drives the needle to penetrate into the skin of the patient's wound. The baffle 407 assists in pushing the needle to penetrate into the skin better. After the needle penetrates the skin, the first clamping member 1 and the second clamping member 2 are flipped 180 degrees. Then the clamping plate 404 clamps the needle and pulls the needle out from the other end of the skin, thereby achieving the effect of assisting the needle in suturing the wound. The rubber pad 408 further fixes the needle, thereby solving the problem that the clamping force of the traditional needle threading clip on the needle is limited. When the needle is clamped for auxiliary suturing of the wound, the needle is easy to slide with the needle threading clip, thereby reducing the work efficiency of suturing the patient's wound.

[0033] like Figure 5 and Figure 6As shown, a cutting device 5 is provided on the surface of the baffle 407, and the cutting device 5 includes a fixed plate 51, a surface of the fixed plate 51 is fixedly connected to the baffle 407, a surface of the fixed plate 51 is slidably connected to a movable plate 52, an end of the movable plate 52 away from the fixed plate 51 is fixedly connected to a connecting plate 53, a side of the connecting plate 53 close to the movable plate 52 is evenly fixedly connected to a second spring 54, an end of the second spring 54 away from the connecting plate 53 is fixedly connected to the fixed plate 51, a blade 55 is clamped on an end of the movable plate 52 away from the fixed plate 51, a connecting cloth 56 is fixedly connected to the side of the connecting plate 53 away from the movable plate 52, and a hook 57 is fixedly connected to the end of the connecting cloth 56 away from the connecting plate 53. The two blades 55 will cut the suture thread of the needle at this time, so as to cut the excess suture thread at the end of suturing. The second spring 54 will give a pulling force to the connecting plate 53 so that the connecting plate 53 drives the movable plate 52 to move, and the movable plate 52 drives the blade 55 to move. The end of the hook 57 away from the connecting cloth 56 is slidably connected with a buckle, and the end of the buckle away from the hook 57 is fixedly connected with the baffle 407. The hook 57 is hung on the buckle, and the connecting cloth 56 will fix the position of the connecting plate 53, thereby achieving the effect of fixing the position of the connecting plate 53 and facilitating the cutting of the suture line next time. The end of the movable plate 52 away from the connecting plate 53 is provided with a slide groove 58, and the inner wall of the slide groove 58 is slidably connected with a slider 59, and the side of the slider 59 away from the inner wall of the slide groove 58 is fixedly connected with the blade 55.

[0034] The effect achieved by the entire cutting device 5 is that, by setting the cutting device 5, when the suture thread of the needle needs to be cut after the wound is sutured, the slider 59 on the sterilized blade 55 is first aligned with the movable plate 52, and then the slider 59 is slid into the slide groove 58 of the movable plate 52. The slider 59 and the slide groove 58 facilitate the installation and removal of the blade 55. Then the hook 57 is pulled out from the buckle of the baffle 407. At this time, the second spring 54 will give a pulling force to the connecting plate 53 so that the connecting plate 53 drives the movable plate 52 to move, and the movable plate 52 drives the blade 55 to move, and the tips of the two blades 55 will contact On the suture surface of the needle, the two blades 55 will cut the suture of the needle at this time, so as to achieve the effect of cutting the excess suture at the end of suturing. After cutting, pull the hook 57 and hang the hook 57 on the buckle, and the connecting cloth 56 will fix the position of the connecting plate 53. At this time, the position of the movable plate 52 is fixed, and the position of the blade 55 is also fixed, thereby fixing the position of the connecting plate 53, and then achieving the effect of facilitating the cutting of the suture next time, solving the problem that the traditional needle and thread clip can only assist in needle threading. After needle threading, the suture needs to be cut with scissors, which reduces the efficiency of wound suturing.

[0035] like Figure 7 and Figure 8 As shown, a limiting device 6 is provided on the surface of the first clamping member 1, and the limiting device 6 includes a first clamping plate 61. The surface of the first clamping plate 61 is fixedly connected to the first clamping member 1. Two elastic cloths 62 are evenly and fixedly connected to the surface of the first clamping plate 61.

One end of the rotating shaft 64 is fixedly connected to a handle 65, and the surface of the handle 65 is evenly provided with anti-slip protrusions. When the handle 65 is turned, the handle 65 drives the rotating shaft 64 to rotate. The rotating shaft 64 begins to wrap around the elastic cloth 62, and the elastic cloth 62 will pull the first clamping plate 61 to move toward the second clamping plate 63.

[0036] The effect achieved by the entire limiting device 6 is that by setting the limiting device 6, when the needle and thread clip is used, the latch 66 is first pulled to pull the latch 66 out of the clamping hole of the handle 65, and then the handle 65 is turned. At this time, the handle 65 drives the rotating shaft 64 to rotate, and the rotating shaft 64 begins to wrap around the elastic cloth 62. The length of the elastic cloth 62 will decrease accordingly, and the elastic cloth 62 will pull the first clamping plate 61 to move toward the second clamping plate 63. The first clamping plate 61 and the second clamping plate 63 will fix the two holding drive rods 3 in the middle, thereby achieving the effect of fixing the position of the first clamping member 1 and the second clamping member 2. Then the latch 66 is re-inserted into the clamping hole of the handle 65, thereby achieving the effect of fixing the position of the handle 65, and then fixing the position of the rotating shaft 64, so that the clamp can be kept stably closed during operation, and there is no need to manually hold and clamp for a long time.
