Problems solved by technology

[0005] Aiming at the problem that the current bone fracture site is repeatedly wound with a rope on the exposed part of the nail piercing and finally tied with a knot, which causes the sutured muscle to protrude, brings discomfort and affects blood circulation, the present invention provides a binding-free fixation method for fractures. The fixed belt tensioner used in combination with the fixed belt set and the fixed belt set is used to simplify the operation procedure, improve the operation efficiency and reduce the difficulty of the operation

Embodiment 1

[0038] Embodiment 1: The flat-shaped tying-free fixing member can be applied and fixed on both sides of the fracture site. When it is tensioned and fixed, the distal and proximal ends of the fracture are tightened and fixed, which can significantly reduce the protrusion and improve the operation efficiency. Reduce the difficulty of surgery, improve blood circulation to facilitate the recovery of patients, improve the comfort of patients and other advantages. In order to fast fix the non-binding fastener, it is necessary to respectively provide the main collars at both ends of the non-binding fastener with axially outward pulling tension. Such as figure 1 As shown, the flat-shaped strap-free fixation member 15 includes a pair of front loops 16 at the front end and a pair of rear loops 17 at the rear end. Usually, when it is fixed, a hole is drilled at the distal end of the fracture and the front loop is placed. The ring 16 is set in the hole positions on both sides of the dril...

Embodiment 2

[0044] Embodiment 2: This embodiment provides a general-purpose pliers body, which is based on Embodiment 1, and the expansion and contraction is set between the left and right forks of the front tension fork 4 and / or the rear tension fork 5 Institution 9. That is: the front tension fork 4 and / or the rear tension fork 5 include two left and right forks that can slide relatively, and an expansion-contraction mechanism 9 is arranged between the two forks.

[0045] Such as figure 2 with Figure 10 As shown, the expansion-contraction mechanism 9 in this embodiment includes a rectangular housing 91, the middle part of the front and rear end surfaces of the housing 91 is transparent to form an inner cavity 92, and the left and right end walls of the inner cavity are respectively provided with non-circular end holes 93. A hand wheel 94 is set in the inner cavity 92 , the diameter of the first wheel is greater than the thickness between the front and rear end surfaces of the housin...

Embodiment 3

[0048] Embodiment 3: a kind of as Figure 4-Figure 6 The shown pliers body has the same main body structure as the pliers body in Embodiment 2, except that: (1) it is vertically fixed on the inner side of the two prongs of the rear tension fork 5 and faces the opposite columnar rod 14 . (2) Each fork of the front tension fork 4 and / or the rear tension fork 5 has a telescopic adjustment structure and a locking structure.

[0049] When the columnar rod 14 in other (1) is applied, it is necessary to directly insert the two columnar rods 14 at the lower end of the rear tension fork rod 5 into the drilled hole at the proximal end of the fracture after drilling the proximal end of the fracture, so that it is no longer used such as The support rod 21 in Embodiment 1. It can be seen that when this embodiment is applied, the expansion and contraction mechanism 9 as described in Embodiment 2 must be used. When in use, it is necessary to first adjust the rear tension fork rods 5 on bot...

Abstract

The invention discloses a strapping-free fixing axial tensioning clamp for fracture, which comprises a front tension fork rod connected with a traction part of a strapping-free fixing piece, a rear tension fork rod connected with a fixed part, and a tension mechanism for exerting tension between the front tension fork rod and the rear tension fork rod to enable the front tension fork rod and the rear tension fork rod to be inward, so that the traction part of the strapping-free fixing piece is pulled outwards to be in a tensioning state. An expansion and contraction mechanism is arranged between the left fork rod and the right fork rod of the front tension fork rod or the rear tension fork rod. The invention provides a pair of tensioning pliers capable of quickly fixing a flat strapping-free fixing piece, which has the advantages of obviously simplifying the operation procedure, improving the operation efficiency, reducing the operation difficulty and the like. The tool has a self-holding function and can be independently supported after tension is generated in use, so that the tool is suitable for drilling, clamping, traction, fixing and other operation processes through one-man operation, and the tool is easy to operate, standard, high in efficiency and good in effect.

Description

technical field [0001] The invention belongs to the technical field of fracture reduction and fixation tools, and in particular relates to a tool for traction and fixation of fracture sites with free flexible fixation parts. Background technique [0002] The common surgical treatment methods for the fixation of femoral shaft fractures include plate fixation and intramedullary nail fixation. Plate fixation has the advantages of simple operation and short learning period, but the trauma is large and the probability of accidental injury is high. Many matching models are required. Healing, delayed healing, broken nails and broken plates occur from time to time, and the postoperative scars are large, which affects the appearance and does not conform to the principle of minimally invasive. The intramedullary nail adopts closed and minimally invasive technology. The locking intramedullary nail can prevent fracture rotation deformity, reduce the risk of implant fracture, reduce the ...
