[0002] Nowadays, minimally invasive surgery has been fully popularized, and minimally invasive surgery can reduce the pain of patients and accelerate the recovery of patients, so it is deeply loved by patients and doctors. At present, whether minimally invasive surgery can be performed is considered first in all surgeries, so the innovation of minimally invasive surgical instruments is also extremely important.

By rotating the rotating wheel shaft on the fixed shaft, the forceps rod connected with the rotating wheel is driven to rotate, and the rotation of the forceps head is realized. The innovation of the patent for rotation lies in the feature of realizing rotation by using the forceps head, but in actual surgery, the forceps head is away from the operator at one end. At this time, the rotation of the forceps head is realized by rotating the rotating wheel close to the operator, which is very difficult to control the rotation angle of the forceps head. If the rotation angle of the forceps head deviates from the rotation angle of the rotating wheel, the operator needs to have enough experience in using the device and cooperate with a close-range visual observation device to realize accurate rotation. Moreover, the rotating structure is too complex, and many accessories are needed. In the case of damage to a certain accessory, it needs to be disassembled, replaced and adjusted in precision, and the repair process and repair cycle are too long. CONTENT OF THE UTILITY MODEL

[0023] As Figures 1 to 10 shown, a split type continuous firing clip applier, it includes handle assembly 1, forceps lever assembly 2 and clamping structure 3;The handle assembly 1 and forceps lever assembly 2 are connected by clamping structure 3 and are connected;The front end of the forceps lever assembly 2 is connected with forceps head assembly 4, and the forceps head assembly is movably connected with the handle assembly 1 through the movable control assembly arranged in the forceps lever assembly 2;

[0024] The clamping structure 3 includes two clamping rings 31, and the clamping ring 31 includes a U-shaped part 311 and a pressing part 312, the two ends of the U-shaped part 311 are fixedly connected with the pressing part 312, and the two ends of the U-shaped part 311 are both provided with notches 313;So that the two U-shaped parts 311 are arranged together through the notches 313 to form a complete clamping groove, the U-shaped part 311 is embedded in the handle assembly 1, and the pressing part 312 is movably connected to the outer side of the front part of the handle assembly 1;

[0025] The inner side of the U-shaped part 311 is provided with a plurality of arc clamping pieces 314;The inner side of the pressing part 312 is fixedly connected with an annular elastic piece 315;So that the outer side of the U-shaped part 311 of the clamping ring 31 is in abutment with the annular elastic piece 315 of the other clamping ring 31;The clamping structure 3 further includes the connecting pipe 21 arranged at the rear end of the forceps lever assembly 2, and a plurality of equidistantly distributed clamping grooves 211 are arranged on the outer periphery of the connecting pipe 21, and the clamping grooves 211 are connected with the arc clamping pieces 314.

[0026] It should be noted that the forceps lever assembly can be connected and replaced, which can realize simple and rapid supplement or replacement of the ligature clip, can quickly replace different models of ligature clips in surgery, and can quickly supplement the ligature clip to save the operation time, without preparing too many similar instruments, and reducing the number of surgical instruments.

[0027] Further, the card slot 211 is an annular groove, and multiple annular grooves are arranged on the outer periphery of the connecting pipe 21; so that the circular arc card 314 is limitedly connected with the annular groove, and the circular arc card 314 can also rotate freely by 360 degrees around the annular groove, thereby realizing the function that the clamp rod assembly 2 rotates freely by 360 degrees around the handle assembly 1.

[0028] It should be noted that the design of the annular groove can realize the detachable and limited rotation structure by using the clamping structure, has the advantages of simple structure, few required parts and complete functions, and can realize 360-degree free rotation, so that the operator has more operation space.

[0029] Further, the two sides of the front part of the handle assembly 1 are provided with embedding grooves, and the two clamping rings 31 are embedded in the corresponding embedding grooves respectively; so that the two U-shaped parts 311 are arranged together to form a complete clamping groove in the interior of the handle assembly 1. The structure of the embedding groove is a conventional technical means, and therefore will not be described in detail.

[0030] Further, the rear end of the clamp rod assembly 2 is provided with a rotating wheel 22, and the connecting pipe 21 is connected to the rear end of the rotating wheel 22. The rotating wheel 22 is a conventional technical means, and therefore will not be described in detail.

[0031] Further, the outer side of the pressing part 312 is also provided with anti-skid lines 316.

[0032] It should be noted that the anti-skid lines can make the structure of the pressing part 312 clearer and more visible, and can prevent the fingers of the operator from slipping off the pressing part 312 during operation, thereby avoiding unnecessary influence.

[0033] When the handle assembly 1 and the clamp rod assembly 2 are connected, the U-shaped part 311 of the two clamping rings 31 is pushed out by the annular elastic piece 315, the arc-shaped card 314 is limitedly protruded, and the connecting pipe 21 of the clamp rod assembly 2 cannot enter the interior of the handle assembly, and the specific structure is as shown in Figure 4 ;

[0034] Then, the two fingers press the pressing parts 312 on both sides of the handle assembly at the same time, the annular elastic piece 315 is stressed to extrude the U-shaped part 311, so that the arc-shaped card 314 is contracted, and the specific structure is as shown in Figure 5 ; At this time, the connecting pipe 21 can be inserted into the handle assembly 1;

[0035] Then, the pressing part 312 is loosened, the annular elastic piece 315 resets to push out the arc-shaped card 314, so that the arc-shaped card 314 is connected with the card slot 211, and the handle assembly 1 and the clamp rod assembly 2 are connected. After the connection, based on the design that the card slot 211 is an annular groove and multiple annular grooves are arranged on the outer periphery of the connecting pipe 21, the clamp rod assembly 2 of the utility model can also realize the function of 360-degree free and rapid rotation, thereby further meeting the operation requirements of the operator;

[0036] It should be noted that the process of disassembling the handle assembly 1 from the plier lever assembly 2 is the reverse of the above process, and thus will not be described in detail.

[0037] Although the utility model is demonstrated and described by specific embodiments and alternative ways, it should be understood that various changes and modifications within the spirit range of the utility model can be implemented. Therefore, it should be understood that the utility model is not limited in any sense except for the appended claims and their equivalent conditions.
