Abstract
The present invention discloses bone holding forceps with a steel wire guide, including a fixed rod and a movable rod, where a front end of the fixed rod includes a first clamping portion in a hook shape, a front end of the movable rod includes a second clamping portion facing the first clamping portion, and the first clamping portion and the second clamping portion are in an enclosed state for clamping and fixing a femur; and a hollow pipe used for threading a steel wire is fixed on a back side of the front end of the fixed rod. In the present invention, a hollow pipe used for threading a steel wire is provided on a back of a front end of a fixed rod, and with the help of the hollow pipe, a doctor can thread the steel wire before taking out bone holding forceps, and complete two original operation steps (fixing a femur with bone holding forceps and winding a steel wire) in one step, so that an operation process is simplified, an operation time is shortened, and pain of a patient is alleviated.
Description
BL-5159 1 LU101930
[0001] The present invention relates to bone holding forceps for fixing a femur and belongs to the field of medical instrument technologies.
[0002] Fracture is one of the most common diseases in orthopedics. In open reduction and internal fixation (ORIF) operations for a fracture, two broken ends of the fracture are usually clamped with instruments, such as bone holding forceps, for reduction, and then are fixed with internal fixation materials. For a femoral fracture, a steel wire often needs to be used for strapping and fixation.
[0003] In current operations, a steel wire is threaded after bone holding forceps are taken out, and a process of threading the steel wire is usually completely manually operated without using an auxiliary tool. On the one hand, a fracture reduction effect may be lost during this operation process, and reduction needs to be performed again; and on the other hand, because there is no auxiliary tool, threading of the steel wire is not fast enough, which prolongs an operation time and causes pain to a patient.
SUMMARY OF THE INVENTION Technical Problem
[0004] An objective of the present invention is overcome the foregoing defects in BACKGROUND and provide bone holding forceps with a steel wire guide, to facilitate threading a steel wire in an operation and shorten an operation time. Technical Solution
[0005] To achieve the foregoing objective, the present invention provides the
BL-5159 2 following technical solution: bone holding forceps with a steel wire guide, including a HU107930 fixed rod and a movable rod, where a front end of the fixed rod includes a first clamping portion in a hook shape, a front end of the movable rod includes a second clamping portion facing the first clamping portion, and the first clamping portion and the second clamping portion are in an enclosed state for clamping and fixing a femur; and a hollow pipe used for threading a steel wire is fixed on a back side of the front end of the fixed rod. Beneficial Effects
[0006] In the present invention, a hollow pipe used for threading a steel wire is provided on a back of a front end of a fixed rod, and with the help of the hollow pipe, a doctor can thread the steel wire before taking out bone holding forceps, and complete two original operation steps (fixing a femur with bone holding forceps and winding a steel wire) in one step, so that an operation process is simplified, an operation time is shortened, and pain of a patient is alleviated.
[0007] FIG. 1 is a schematic structrual diagram of bone holding forceps with a steel wire guide.
[0008] Reference signs in the drawing are described as follows: 1-fixed rod; 11-first clamping portion; 12-hollow pipe; 2-movable rod; 21-second clamping portion; 22-slide block; 3-screw rod; and 31-spin handle.
[0009] The present invention is further described below with reference to the accompanying drawing and specific embodiments.
[0010] As shown in FIG. 1, in this embodiment, bone holding forceps with a steel wire guide are provided, including: a fixed rod 1 and a movable rod 2 slidably disposed on an inner side of the fixed rod 1. In this embodiment, the fixed rod 1 is
BL-5159 3 provided with a slide groove, and the movable rod 2 is provided with a slide block HU107930 fitting the slide groove. A tail screw thread of the fixed rod 1 is connected to a screw rod 3, and a head of the screw rod 3 is movably connected to a tail of the movable rod
2. A spin handle 31 is fixed onto a tail of the screw rod 3. The screw rod 3 is spinned by using the spin handle 31, to move the movable rod 2 forward or backward.
[0011] A front end of the fixed rod 1 includes a first clamping portion 11 in a hook shape. A front end of the movable rod 2 includes a second clamping portion 21 facing the first clamping portion 11. The first clamping portion 11 and the second clamping portion 21 are in an enclosed state for clamping and fixing a femur. As shown in FIG. 1, the first clamping portion 11 and the second clamping portion 21 have sawtooth structures, to prevent slippage, so that the femur can be clamped more firmly.
[0012] A hollow pipe 12 used for threading a steel wire is fixed on a back side of the front end of the fixed rod 1. The hollow pipe 12 is in an arc shape, and fits a back of a hook head the fixed rod 2, to facilitate threading of the steel wire. In this embodiment, a hole diameter of the hollow pipe 12 is 3 mm.
[0013] During an operation, after a femur is reduced and fixed by using the bone holding forceps, the steel wire is threaded through the hollow pipe 12. A head end of the steel wire is held, and then the bone holding forceps are taken out. A tail end of the steel wire slides out of the hollow pipe, and then, the two ends of the steel wire are tightly twisted together with steel wire pliers to complete binding and fixation of the femur.
[0014] In a preferable solution, a side face of the hollow pipe 12 close to a head of the fixed rod 1 is provided with a gap for a steel wire to slide out. In this way, the steel wire can slide out of the hollow pipe 12 when the bone holding forceps perform fixation, the femur is first bound and fixed with the steel wire, then, and then, the bone holding forceps are removed, to prevent loss of a fracture reduction effect.
[0015] In addition to the foregoing embodiments, the present invention may further include other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope claimed in the present invention.
