Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a finger sleeve type minimally invasive knot pusher. BACKGROUND

[0002] The knot pusher is an important tool used in surgery to handle suture knot. In minimally invasive surgery, especially for some deep tissue suture operation, when the knot needs to be tightened, the knot pusher plays a key role. Its design is usually long and has a specific structure, which can adapt to the space limitation of the operation site and accurately operate the suture. To ensure that the line knot is effectively pushed and tightened without damaging the surrounding tissue.

[0003] However, the minimally invasive knot pusher currently used in the market has the following shortcomings: first, the knot operation needs to be completed by the main surgeon and the assistant (one person completes the open surgery that is not minimally invasive). Thus, the risk is that the main surgeon cannot completely control the knot tension with the assistant when the assistant pulls the line at one end. Thin lines are prone to breakage, and thick lines are not easy to tighten. Second, the existing minimally invasive knot pusher is expensive and is an integral structure, which cannot be disassembled, making it difficult to repair and replace the parts of the knot pusher. Once a part is damaged or worn out, the entire knot pusher needs to be replaced, increasing the cost of using the knot pusher. SUMMARY

[0004] The main purpose of the utility model is to provide a finger sleeve type minimally invasive knot pusher to overcome or improve at least one technical problem of the prior art, or to provide a useful alternative.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

One side of the finger sleeve is provided with a protrusion, and a clamping groove is formed in the inside of the protrusion. The connecting rod is detachably installed in the clamping groove. The knot pushing ring is arranged at the upper end of the connecting rod. The knot pushing ring has a ring structure. One end of the knot pushing ring is provided with an elastic sheet. The elastic sheet extends to the inside of the other end of the knot pushing ring, and the end of the elastic sheet abuts against the inner wall of the other end of the knot pushing ring.

[0007] Further, the included angle between the knot pushing ring and the connecting rod is 30°-60°.

[0008] Further, the front view of the finger sleeve is a circular truncated cone structure. The inner diameter of the upper end of the finger sleeve is smaller than the inner diameter of the lower end of the finger sleeve. The height of the finger sleeve corresponds to the length of the first knuckle of the index finger or middle finger.

[0009] Further, the finger sleeve part and the protruding block are integrally formed, and the connection part between the finger sleeve part and the protruding block is in a curved surface structure.

[0010] Further, the gap between the end of the elastic sheet not provided with the knot pushing ring and the front end of the elastic sheet gradually decreases from the front end to the end of the elastic sheet, and the end of the end of the elastic sheet not provided with the knot pushing ring is in a circular arc structure.

[0011] Further, the connecting rod is provided with a mounting assembly for stably connecting the connecting rod and the finger sleeve part.

[0012] Further, the mounting assembly comprises a limiting block and a positioning shaft, the inside of the connecting rod is provided with a sliding groove, the inside of the sliding groove is connected with a spring, the other end of the spring is fixedly connected with the limiting block, the other end of the limiting block is fixedly connected with the positioning shaft, the outer surface of the protruding block is provided with a positioning hole, the positioning shaft and the positioning hole are connected in a clamping connection mode, and the length of the positioning shaft is greater than the depth of the positioning hole.

[0013] Further, the diameter of the limiting block is greater than the diameter of the positioning shaft, and the spring connected by the limiting block constitutes a telescopic structure in the sliding groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] By setting the elastic sheet at one end of the knot pushing ring, the elastic sheet extends to the inside of the other end of the knot pushing ring, and the end of the elastic sheet abuts against the inner wall of the other end of the knot pushing ring, so that the rope can be ensured to be inserted into the inside of the knot pushing ring, and the rope can be prevented from sliding out of the inside of the knot pushing ring when the knot pushing ring is used; when a doctor performs an operation, the knot pushing device does not need an assistant, and the doctor can complete knotting by operating alone, and can better control the knotting force, thereby improving safety.

[0016] The connecting rod is detachably installed in the clamping groove, and the connecting rod and the finger sleeve part are stably connected through the mounting assembly on the connecting rod, so that the connecting rod and the finger sleeve part can be quickly installed and detached, thereby facilitating maintenance and replacement of each part of the knot pushing device and being beneficial to reducing the use cost of the knot pushing device.

[0026] As preferred, one end of push knot ring 10 not being equipped with elastic sheet 11 and the front end of elastic sheet 11 exist gap, gap is gradually reduced along the front end to the end of elastic sheet 11, and the gap at the end of elastic sheet 11 is zero, that is, the end of elastic sheet 11 and the inner wall of one end of push knot ring 10 not being equipped with elastic sheet 11 abut.Using this scheme, line is more easily entered into the inside of push knot ring 10 from gap, doctor is more convenient when operating, reduces the operation time of doctor.

[0027] As preferred, the end of one end of push knot ring 10 not being equipped with elastic sheet is circular arc structure 12.

[0028] It is worth mentioning that: the connecting rod 5 and the finger sleeve part 1 can be quickly disassembled or installed by using the mounting assembly, which is convenient for storage in the limited space in the operation, improves the carrying convenience of the knot pusher, and is convenient for maintenance and replacement of each part of the knot pusher. In addition, when the finger sleeve part 1 is frequently rubbed and has slight cracks, or the connecting rod 5 and the knot pushing ring 10 are damaged, the connecting rod 5 and the finger sleeve part 1 can be disassembled, and the intact parts can be installed with other intact parts, thereby reducing the use cost of the knot pusher.

[0029] Please refer to Figures 1-2 , the front view of the finger sleeve part 1 is a circular truncated cone structure, the inner diameter of the upper end of the finger sleeve part 1 is smaller than the inner diameter of the lower end of the finger sleeve part 1, and the height of the finger sleeve part 1 corresponds to the length of the first knuckle of the index finger or the middle finger.

[0030] It should be noted that: since the inner diameter of the finger sleeve part 1 gradually decreases from the bottom to the top, the finger sleeve part 1 is suitable for the wearing needs of medical staff of different finger dimensions, thereby avoiding the situation that the finger sleeve part 1 is too tight or too loose. For the height of the finger sleeve part 1, a single main surgeon can be customized according to the length of the first knuckle of the index finger or the middle finger.

[0031] As a preferred, the included angle between the knot pushing ring 10 and the connecting rod 5 is 30°-60°.

[0032] Please refer to Figures 1-6 , the inside of the connecting rod 5 is provided with a mounting assembly, the mounting assembly is used for stably connecting the connecting rod 5 and the finger sleeve part 1, the mounting assembly includes a limiting block 8 and a positioning shaft 9, the inside of the connecting rod 5 is provided with a sliding groove 6, the inside of the sliding groove 6 is connected with a spring 7, the other end of the spring 7 is fixedly connected with the limiting block 8, the connecting mode between the limiting block 8 and the positioning shaft 9 is fixed connection, the outer surface of the protruding block 2 is provided with a positioning hole 4, the connecting mode between the positioning shaft 9 and the positioning hole 4 is clamping connection, and the length of the positioning shaft 9 is greater than the depth of the positioning hole 4.

[0033] The principle of quickly disassembling and assembling the connecting rod 5 and the finger sleeve part 1 is that when the connecting rod 5 and the finger sleeve part 1 need to be disassembled, the positioning shaft 9 is first pushed into the inside of the connecting rod 5, so that the positioning shaft 9 slides into the inside of the sliding groove 6 and is separated from the positioning hole 4, then the connecting rod 5 is pulled upwards, so that the connecting rod 5 slides out from the inside of the clamping groove 3, at this time, the connecting rod 5 and the finger sleeve part 1 are disassembled; when the connecting rod 5 and the finger sleeve part 1 need to be assembled, the positioning shaft 9 is first pushed into the inside of the connecting rod 5, so that the positioning shaft 9 completely slides into the inside of the sliding groove 6, and in this process, the spring 7 connected with the limiting block 8 is compressed, then the connecting rod 5 is inserted into the inside of the clamping groove 3, when the connecting rod 5 is inserted into the lowermost end of the clamping groove 3, at this time, the positioning shaft 9 is just corresponding to the positioning hole 4, then the spring 7 pushes the limiting block 8 connected with the positioning shaft 9 to extend from the inside of the sliding groove 6, so that the positioning shaft 9 is clamped and connected with the positioning hole 4, through the clamping and connecting of the positioning shaft 9 and the positioning hole 4, the connecting rod 5 and the finger sleeve part 1 are stably connected, so as to ensure the normal use of the push knotter.

[0034] Please refer to Figure 4 The diameter of the limiting block 8 is greater than the diameter of the positioning shaft 9, and the positioning shaft 9 constitutes a telescopic structure in the inside of the sliding groove 6 through the spring 7 connected with the limiting block 8.

[0035] The limiting block 8 has the following effects: since the diameter of the limiting block 8 is greater than the diameter of the positioning shaft 9, and the diameter of the front end of the sliding groove 6 is smaller than the diameter of the tail end of the sliding groove 6, the movement of the positioning shaft 9 can be limited through the limiting block 8, so as to prevent the positioning shaft 9 from completely sliding out from the inside of the sliding groove 6.

[0036] The above is only the preferred embodiment of the present application, and does not limit the technical scope of the present application, so any slight modification, equivalent change and modification according to the technical essence of the present application are still within the scope of the technical scheme of the present application.
