The finger fixing plate is connected to the connection inner shaft, and the palm fixing plate is connected to the connection collar;

[0008] A fixing band is provided at the bottom of the palm fixing plate, and a protective pad is provided at the upper part of the palm fixing plate.

[0009] The connecting collar can be locked or loosened by rotating the eccentric paddle. When the connecting collar locks the connecting collar, the connecting collar cannot rotate relative to the connecting collar, thereby fixing the finger fixing plate and the palm fixing plate at a certain angle relative to each other. When the connecting collar loosens the connecting collar, the connecting collar can rotate relative to the connecting collar, thereby facilitating the adjustment of the angle between the finger fixing plate and the palm fixing plate.

[0011] The spacing of the openings is varied to allow the connecting collar to tighten or loosen the inner shaft.

[0012] Furthermore, the eccentric paddle is in contact with one of the flanges, and a locking nut is provided at one end of the locking screw away from the eccentric paddle.

[0013] The locking nut is matched with the locking screw thread, and the distance between the two flanges can be changed by rotating the eccentric paddle, thereby changing the opening spacing and adjusting the clamping tightness of the connecting collar on the connecting inner shaft.

[0014] Furthermore, the finger fixing mechanism and the locking mechanism are each provided with at least five groups, the front end of the palm fixing plate is arc-shaped, and the spacing between the finger fixing mechanisms close to one end of the palm fixing plate is smaller than the spacing away from one end of the palm fixing plate.

[0015] The finger fixing mechanisms are separated rather than close together, which is convenient for leaving space for surgery. Sometimes six-finger surgery is performed, and the corresponding finger fixing mechanisms and locking mechanisms need to have six groups.

[0016] Furthermore, the outer side of the connecting ring is fixedly connected to the front end of the palm fixing plate, the connecting inner shaft is arranged in the inner cavity of the connecting ring, and the finger fixing plate is fixedly connected to the end of the connecting inner shaft.

[0017] Furthermore, the hemostatic bandage is movably plugged into and penetrates the bandage mounting block.

[0018] Furthermore, a connecting lock block is provided at one end of the hemostatic bandage, the connecting lock block has a through slot penetrating the connecting lock block, and a connecting lock shaft is provided in the through slot.

[0019] Furthermore, the finger fixing mechanism has at least two strap mounting blocks, and each of the strap mounting blocks is provided with a hemostatic strap.

[0020] Further, fixing straps are respectively provided at the front end and the rear end of the bottom of the palm fixing plate to fix the patient's wrist and palm.

[0021] Further, the protective pad is detachably connected to the palm fixing plate, and the material of the protective pad is skin-friendly silicone material. By replacing the disposable protective pad, other parts can be reused after disinfection, reducing costs.

[0022] The technical solution provided by this application may include the following beneficial effects:

[0023] Through the setting of the locking mechanism, the finger fixing plate can be quickly clamped and fixed or released, so as to quickly adjust the included angle formed between the finger fixing plate and the palm fixing plate, solving the problems of slow adjustment speed and complicated adjustment steps of the existing equipment, resulting in the inability to fix the hand in time and delaying the actual work progress.

[0024] Through the setting of the finger fixing mechanism, the use position of the hemostatic strap can be adjusted according to the finger lengths of different users. And through the setting of the connecting lock block and the connecting lock shaft, it is not only convenient to connect the hemostatic straps, but also convenient to adjust the tightness of the hemostatic straps. This method is simple and fast to operate, thus improving the applicability and convenience of this device.

[0038] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] As Figures 1 to 4 shown, an external fixation hemostasis device for the hand provided by an embodiment of the present application includes a palm fixing plate 1, a finger fixing mechanism 2, and a locking mechanism 3. The palm fixing plate 1 and the finger fixing mechanism 2 are connected by the locking mechanism 3. The locking mechanism 3 includes a connecting collar 301, a connecting inner shaft 302, a locking screw 303, and an eccentric dial 304. A fixing strap 4 is provided at the bottom of the palm fixing plate 1, and a protective pad 5 is provided at the upper part of the palm fixing plate 1.

[0040] Specifically, there are five groups of both the finger fixing mechanism 2 and the locking mechanism 3. The front end of the palm fixing plate 1 is arc-shaped. The distance between the finger fixing mechanisms 2 near one end of the palm fixing plate 1 is smaller than the distance between the finger fixing mechanisms 2 far from one end of the palm fixing plate 1, that is, the palm fixing plate 1 and the finger fixing mechanism 2 are arranged corresponding to the open state of the fingers of the entire hand. There are two groups of fixing straps 4, and the fixing straps 4 are respectively arranged at the front end and the rear end of the bottom of the palm fixing plate 1. The material of the protective pad 5 is a skin-friendly silicone material.

[0041] Among them, the outside of the connecting collar 301 is fixedly connected to the front end of the palm fixing plate 1. The connecting inner shaft 302 is sleeved in the inner cavity of the connecting collar 301. The locking screw 303 is inserted through the flange at the opening on the outside of the connecting collar 301. The eccentric dial 304 is movably connected to one end of the locking screw 303. The eccentric dial 304 can rotate relative to the locking screw 303. The eccentric dial 304 abuts against the flange on one side. The other end of the locking screw 303 is fixedly connected to the flange on the other side through a locking nut.

[0042] When in use, by pulling up the eccentric dial 304, the thinnest part of the eccentric dial 304 is fitted to the opening of the connecting collar 301, so that the part of the locking screw 303 inside the connecting collar 301 becomes longer, and the connecting collar 301 loses the clamping and fixing of the connecting inner shaft 302, so that the connecting inner shaft 302 can rotate. Then, according to the actual use requirements, the appropriate angle is adjusted between the corresponding finger fixing plate 201 and the palm fixing plate 1. Then, the eccentric dial 304 is pressed down, and the thickest part of the eccentric dial 304 is fitted to the opening of the connecting collar 301, so that the connecting collar 301 clamps and fixes the connecting inner shaft 302, so as to complete the fixed position of each finger fixing plate 201 of the device according to the requirements. Subsequently, the back of the hand is attached to the surface of the protective pad 5 and placed in a suitable position, and then the fixing strap 4 is used to fix the device to the back of the hand.

[0043] By setting the locking mechanism 3, the finger fixing plate 201 can be quickly clamped and fixed or released, so as to quickly adjust the included angle formed between the finger fixing plate 201 and the palm fixing plate 1, solving the problems of slow adjustment speed and complicated adjustment steps of the existing equipment, resulting in the inability to fix the hand in time and delaying the actual work progress.

[0044] As Figure 1 , Figure 4 and Figure 5 shown, in some embodiments, the finger fixing mechanism 2 includes a finger fixing plate 201, a connecting limit block 202, a strap mounting block 203, a hemostatic strap 204, a connecting lock block 205 and a connecting lock shaft 206.

[0045] Specifically, the rear end of the finger fixing plate 201 is fixedly connected to both ends of the connecting inner shaft 302. The connecting limit block 202 is fixedly connected inside the finger fixing plate 201. The strap mounting block 203 is movably clamped outside the connecting limit block 202. The strap mounting block 203 can slide up and down along the connecting limit block 202. The strap mounting block 203 is located inside the finger fixing plate 201. The hemostatic strap 204 is movably inserted and penetrates through the inside of the strap mounting block 203. The connecting lock block 205 is fixedly connected to one end of the hemostatic strap 204. The connecting lock shaft 206 is fixedly connected inside the connecting lock block 205.

[0046] When in use, by attaching the back of the finger to the surface of the finger fixing plate 201, pulling the hemostatic strap 204 according to the finger length requirement to drive the strap mounting block 203 to move, so that the hemostatic strap 204 is in the designated position of the finger. Then, the end of the hemostatic strap 204 penetrates from the inside of the connecting lock block 205 to the outside of the connecting lock block 205, loops around the outside of the connecting lock shaft 206 and then penetrates from the outside of the connecting lock block 205 back to the inside of the connecting lock block 205, and tightens the end of the hemostatic strap 204, so that the hemostatic strap 204 wraps around the finger, and adjusts the tightness of the hemostatic strap 204 wrapped around the finger according to the requirement, realizing the function of fixing the finger to the finger fixing plate 201 or compressing the finger blood vessels to achieve hemostasis.

[0047] By setting the finger fixing mechanism 2, the use position of the hemostatic strap 204 can be adjusted according to the finger lengths of different users. And by setting the connecting lock block 205 and the connecting lock shaft 206, it is not only convenient for the connection between the hemostatic straps 204, but also convenient for adjusting the tightness of the hemostatic strap 204. This method is simple and fast to operate, thus improving the applicability and convenience of the device.
