Description

Technical Field

[0001] The utility model relates to the field of minimally invasive surgical medical instruments, in particular to a retractor and a device for minimally invasive removal of calcaneal spurs. Background Art

[0002] Heel spur is a common disease among the elderly. It is a bone spur that extends forward from the calcaneal tuberosity. Its tip is buried in the plantar fascia and the origin of the flexor tendon of the digitorum brevis. If the patient's heel spur symptoms are more serious, he can undergo a spur removal surgery under the guidance of a doctor. This surgery generally involves surgical removal of the spur to achieve the desired treatment effect.

[0003] In order to reduce trauma to the patient's body and help the patient recover after surgery, minimally invasive surgery is usually used, that is, a 3 cm long minimally invasive incision is made on the patient's foot to remove the heel spur. However, because the minimally invasive incision is small, the doctor's field of view is narrow when removing the root spur, which can easily cause damage to the toe fascia of the foot. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a retractor and device for minimally invasive removal of calcaneal spurs, which is used to solve the problem in the prior art that when using minimally invasive surgery to remove the patient's calcaneal spur, the doctor may accidentally injure the toe fascia of the foot due to the narrow field of vision.

[0005] To achieve the above-mentioned purpose and other related purposes, the utility model provides a minimally invasive resection hook for calcaneal spurs, including a handle, one end of the handle is connected to a partition, one side of the partition is provided with an avoidance opening and a guide plate, the tail end of the partition is provided with a baffle, and the guide plate and the baffle protrude from the same surface of the partition.

[0006] Optionally, the avoidance opening is opened at a position close to the rear end of the partition, and the avoidance opening is semicircular in shape.

[0007] Optionally, the guide plate and the baffle are perpendicular to the surface of the partition.

[0008] Optionally, the edges of the partition, the guide plate, the avoidance opening and the baffle are rounded.

[0009] Optionally, each end of the handle is connected to a partition, and the two partitions have different lengths.

[0010] Optionally, the avoidance openings on the two partitions are of different sizes.

[0011] Optionally, the avoidance openings and the guide plates on the two partitions are located on the same side.

[0012] A device for minimally invasive removal of calcaneal spurs comprises a bone cutter and a minimally invasive removal hook of calcaneal spurs as described above, wherein a cutting edge is arranged at one end of the bone cutter, and a rounded corner is provided on one side of the cutting edge to cooperate with the guide plate.

[0013] Optionally, the width of the osteotome is smaller than the width of the partition.

[0014] Optionally, the thickness of the end of the bone knife with a cutting edge is smaller than the height of the guide plate and the baffle.

[0015] As described above, the utility model of a minimally invasive resection hook and device for calcaneal spur has at least the following beneficial effects:

[0016] 1. The design of the partition for the minimally invasive retractor for heel spur allows the doctor to put the retractor into the incision first when performing the minimally invasive resection of the heel spur. The partition separates the bone spur and the toe fascia, avoiding the problem of the doctor accidentally injuring the toe fascia of the foot due to a narrow field of vision during the operation. The design functions of the avoidance, guide plate and partition on the partition are: the doctor uses a bone knife to slide along the guide plate on the upper surface of the partition to the avoidance to remove the bone spur, and the edge of the avoidance is close to the root of the bone spur, thereby ensuring that the bone knife can completely remove the bone spur without residual bone spur, avoiding adverse effects on the patient's body and mind; after the bone knife removes the bone spur, it will be blocked by the baffle when it continues to slide along the upper surface of the partition, thereby avoiding the bone knife from piercing too deep and causing physical damage to the patient.

[0017] 2. The retractor is connected to a partition plate at each end of the handle, and the two partition plates are designed with different lengths, so that the retractor can be suitable for patients with different foot sizes.

[0018] 3. The retractor is designed with different sizes of avoidance openings on the two partitions, so that the retractor is suitable for patients with different sizes of heel spurs on the feet.

[0019] 4. The retractor is designed to be located on the same side of the avoidance openings and guide plates on the two partitions, so that one retractor can be used for both the left and right feet of the patient.

[0020] 5. The minimally invasive calcaneal bone spur removal device has a rounded corner design on one side of the bone knife's blade, so that the bone knife can move along the guide plate on the partition, and when it moves to the avoidance opening to remove the bone spur, the rounded corner design of the blade can prevent the bone knife from accidentally injuring the toe fascia at the avoidance opening.

[0037] In another embodiment, see Figure 2 The thickness of the end of the bone knife 6 with the blade 7 is less than the height of the guide plate 4 and the baffle 5, ensuring the guiding effect of the guide plate 4 and ensuring the baffle 5 to prevent the bone knife 6 from piercing too deep.

[0038] In other embodiments, we have designed specific dimensions of the bone knife 6 and the retractor, wherein the total length of the handle 1 is 150mm, the lengths of the partitions 2 on both sides are 25mm and 30mm respectively, the height of the guide plate 4 is 2mm, the height of the baffle 5 is 4mm, and the avoidance opening 3 is a semicircular notch with a diameter of 4mm; the total length of the bone knife 6 is 250mm, and the width is 6mm or 8mm; the end of the bone knife 6 with the blade 7 is 1mm thick, and this length area is 30mm, the thickness of the middle area from 30mm-150mm is 3mm to ensure the strength of the entire bone knife 6, the thickness of the tail area from 150mm-250mm is 5mm to ensure that the bone knife 6 is easy to hold, and the angles of the two cut edges of the fillet on one side of the blade 7 are obtuse angles; the above dimensions are the dimensions of the bone knife 6 and the retractor given by the designer of the utility model according to actual surgical conditions, and relevant technical personnel in this field can also make certain adjustments to the dimensions according to their own work experience and work requirements.

[0039] In summary, the utility model uses the design of the partition 2 so that when the doctor performs minimally invasive resection of the calcaneal spur, the doctor first puts the retractor into the incision, and the partition 2 separates the spur A from the toe fascia B, thereby avoiding the problem of the doctor accidentally injuring the toe fascia B of the foot due to a narrow field of vision during the operation. The design function of the avoidance opening 3, the guide plate 4 and the partition 2 on the partition 2 is: the doctor uses the bone knife 6 to slide along the guide plate 4 on the upper surface of the partition 2 to the avoidance opening 3 to remove the bone spur A, and the edge of the avoidance opening 3 is close to the root of the bone spur A, thereby ensuring that the bone knife 6 can completely remove the bone spur A without leaving any bone spur A, thereby avoiding physical and mental damage to the patient. Adverse effects: after the bone knife 6 removes the bone spur A, it will be blocked by the baffle 5 when it continues to slide along the upper surface of the partition 2, thereby preventing the bone knife 6 from piercing too deeply and causing damage to the patient's body; at the same time, the design that the avoidance openings 3 and the guide plates 4 on the two partitions 2 are located on the same side allows the use of one retractor to be applicable to the patient's left and right feet; and the design that the edge 7 of the bone knife 6 has rounded corners on one side allows the bone knife 6 to move along the guide plate 4 on the partition 2, and when it moves to the avoidance opening 3 to remove the bone spur A, the design of the rounded corners of the edge 7 prevents the bone knife 6 from accidentally injuring the toe fascia B at the avoidance opening 3. Therefore, the utility model effectively solves the problems in the prior art and has a high industrial utilization value.
