Problems solved by technology

[0004] The purpose of the present invention is to provide a longitudinal minimally invasive osteotomy for tubular bone, to solve the technical problem that the existing osteotomy cannot perform longitudinal osteotomy on tubular bone and carry out transverse traction to the surgical bone; Long, easy to cause tissue damage around the wound at the osteotomy site and large wound surface, inconvenient operation of the osteotomy and inability to perform rectangular, Z-shaped and S-shaped osteotomies on tubular bones

Embodiment 1

[0039] Embodiment one, see figure 1 , figure 2 , Figure 5 Shown, the operation steps of the present invention when carrying out rectangular osteotomy are as follows:

[0040] Before the operation, first determine the positioning point of the upper end of the surgical bone and the positioning point of the lower end of the surgical bone, cut a small opening in the soft tissue, put the osteotomy drill, and perform the upper end osteotomy on the upper and lower ends of the surgical bone respectively Positioning hole and osteotomy positioning hole at the lower end of the bone. Then confirm the osteotomy point according to the position of the pre-designed longitudinal osteotomy line, cut two small incisions in the soft tissue at both ends of the confirmed osteotomy point for use, place the tubular bone longitudinal minimally invasive osteotomy on the operative bone, A pair of auxiliary positioning pins are respectively inserted into and fixed in the upper end osteotomy position...

Embodiment 2

[0044] Embodiment two: see figure 1 , figure 2 , image 3 , Figure 6 As shown, the present invention can also be applicable to the longitudinal osteotomy of tubular bone in the way of full incision of soft tissue. When implementing the osteotomy operation, at first the upper and lower osteotomy positioning points of the surgical bone are determined, and then the osteotomy positioning hole 26 at the upper end of the surgical bone and the osteotomy positioning hole 27 at the lower end of the surgical bone are made with the osteotomy drill bit, and according to the pre-designed longitudinal Confirm the osteotomy point at the position of the bone line, and make an incision in the soft tissue along the longitudinal osteotomy position equal to the length of the osteotomy line, and place the tubular bone longitudinal minimally invasive osteotomy on the operative bone. The operation method and implementation Example 1 is the same.

Embodiment 3

[0045] Embodiment three: see figure 1 , figure 2 , image 3 , Figure 7 , Figure 8 As shown, when the present invention performs Z-shape and S-shape osteotomy, the operation method is the same as the osteotomy operation steps and methods in Embodiment 1, except that after the longitudinal drilling of the tubular bone and the osteotomy, the upper and lower ends of the tubular bone are drilled horizontally The cutting direction of the osteotomy is opposite to form a longitudinal traction Z-shaped osteotomy site 22 or a longitudinal traction S-shaped osteotomy site 23, and the osteotomy section of the surgical bone is formed into a Z-shape or an S-shape, meeting the needs of longitudinal stretching treatment of tubular bones .

Abstract

A longitudinal minimal-invasion bone cutter for tubular bones comprises a bone cutting end bone cutting device and far end positioning devices. The bone cutting end bone cutting device is slidingly sleeved on a positioning adjusting guide rail which is in a long-strip shape, a sliding groove is arranged in the middle of the positioning adjusting guide rail along the length direction, and scales of the positioning adjusting guide rail are arranged along the sliding groove. The far end positioning devices are symmetrically sleeved at two ends of the positioning adjusting guide rail slidingly. By means of the longitudinal minimal-invasion bone cutter, medical workers can perform longitudinal bone cutting operations on the tubular bones according to treatment needs, and the longitudinal minimal-invasion bone cutter is convenient to operate. When the operations are performed, the longitudinal minimal-invasion bone cutter provides convenience for transverse traction of bone blocks and meets needs of angiitis treatment. The bone cutting operations performed by the aid of the longitudinal minimal-invasion bone cutter belong to minimal-invasion operations, do not damage nerves, blood vessels, soft tissues and periostea, have small invasion, facilitate reconstruction and union of bones, and meet needs of longitudinal traction treatment of the tubular bones. By means of the longitudinal minimal-invasion bone cutter, safety and accuracy of the longitudinal bone cutting operations of the tubular bones are improved, medical workers can conveniently perform the operations, and the operation effect is guaranteed.

Description

technical field [0001] The invention relates to an orthopedic surgical instrument, in particular to an osteotomy device for tubular bone. Background technique [0002] In the past, surgical osteotomies for tubular bones used traditional orthopedic surgical instruments such as straight saws, pendulum saws, ring saws, reciprocating saws, osteotomes, rongeurs, amputators, osteotomists, and bone drills. Open incision, large surgical wound, many bone defects at the osteotomy site, easy to damage the soft tissue and periosteum around the wound, resulting in hematoma and prolonged wound healing, which directly affects postoperative recovery. [0003] At present, there is no osteotomy device specially for osteotomy of tubular bone. During osteotomy, due to the relative length of tubular bone, the size of the osteotomy increases accordingly, so it is difficult to perform osteotomy for deformed bone correction surgery on such long bones; especially in the treatment of veins. In the ...
