Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of a medical fixing retractor according to an embodiment of the present invention; fig. 2 is a schematic view of the medical fixing retractor according to an embodiment of the present invention.
As shown in fig. 1 and 2, an embodiment of the present invention provides a medical fixing retractor, which includes: a drag hook body 10, a fixed needle guide seat 20 and a weight member 30; the retractor body 10 comprises a first section 11 and a second section 12 which are connected, the first section 11 and the second section 12 are arranged at an angle, and one end of the first section 11, which is far away from the second section 12, is provided with a bent hook part 111; the fixing needle guide 20 is disposed on the first section 11 along the extending direction of the first section 11, and has a fixing hole 21 penetrating along the extending direction of the first section 11; the weight member 30 is detachably disposed on the second section 12.
Of course, in other embodiments, the weight member 30 may also be directly fixed on the second section 12 or integrally formed with the second section 12, as long as the weight function is achieved, and the weight of the second section 12 is greater than the weight of the first section 11, which is not limited by the present invention.
In an exemplary embodiment, the retractor body 10 is substantially a flat strip, and is preferably made of medical stainless steel, the first section 11 and the second section 12 are disposed at an angle of substantially 90 °, and optionally, the medical fixing retractor further includes a holding hook 40, and the holding hook 40 is disposed at an end of the second section 12 away from the first section 11, and is used for being held by an operator, so as to improve convenience in use. In use, the first section 11 is generally intended to be arranged in a vertical orientation, a portion of the first section 11 and the hook 111 being inserted around the acetabulum of the patient, the hook 111 being intended to pull and hook over the muscles of the patient; the second section 12 is intended to be arranged substantially horizontally, the second section 12 being intended primarily to be placed over the body 01 of the patient, while the end of the second section 12 remote from the first section 11 extends outside the body of the patient. It should be understood that the first section 11 is not limited to being arranged along the vertical direction, but is not limited to being arranged along the plumb line strictly, and since the direction of the first section 11 is not limited strictly in the operation, the medical fixing hook can achieve the pulling effect within the range of 30 degrees of the first section 11 deviating from the plumb line.
The fixing hole 21 of the fixing needle guide seat 20 can be used for a medical kirschner needle to penetrate, for example, a kirschner needle with a specification of 2.0 can be selected, and optionally, the inner diameter of the fixing hole ranges from 1.5mm to 2.5mm so as to be matched with the diameter of the kirschner needle. In practical use, the kirschner wire can be selectively fixed in the bony structure on or above the posterior wall of the acetabulum after passing through the fixing wire guide seat, so that the first section 11 can be more firmly fixed with the bony structure on or above the posterior wall of the acetabulum, and the weight member 30 can droop under the action of gravity after being assembled on the second section 12 to form a moment in the direction opposite to the moment generated by the fixation of the kirschner wire and the muscle traction, so that the retractor body 10 is stably fixed at a preset position in a force balance way without slipping, the pulled muscle can be reliably fixed in the operation process, the retractor can be continuously operated without an assistant, and the requirement of fully exposing the acetabulum in the operation is ensured. Therefore, the doctor is liberated from heavy operation steps, the fine operation in the operation is more concentrated, and the manual operation errors and the personnel investment are reduced. Further, since the weight member 30 continuously applies force to the hook body 10 under the action of gravity, the muscle pulling effect of the first section 11 and the hook portion 111 can be improved, so that the acetabulum portion can be more fully exposed, and the visual field can be more widely ensured.
In some embodiments, the medical fixing retractor includes the fixing needle guide 20, and the fixing needle guide 20 is disposed at a middle position of the first section 11 in the width direction. Note that, the width direction here refers to a direction in which the length of the cross section of the first section 11 in the direction perpendicular to the extending direction of the first section 11 is larger, and a direction in which the length of the cross section is smaller is the thickness direction. In some cases, only one kirschner wire can be selectively driven, and the medical fixing retractor can only comprise one fixing wire guide seat 20. The fixed needle guide 20 is located at the middle position of the first section 11 along the width direction, so that the stress balance of the first section 11 in the width direction can be maintained, and the stability is better.

The fixing performance of the medical fixing draw hook can be improved by nailing two kirschner wires. The inventor finds that the kirschner wire is nailed into the bony structure of the patient to cause certain damage to the patient, and the kirschner wire is preferably fixed by less kirschner wires on the premise of meeting the fixing performance of the medical fixing drag hook. The inventor finds out through experiments that the fixing performance of the two kirschner wires is enough, and the fixing performance of the medical fixing draw hook is improved without depending on nailing more kirschner wires.
In other embodiments, the medical fixing retractor includes three fixing needle guides 20, two fixing needle guides 20 are disposed at two ends of the first section 11 in the width direction at intervals, and another fixing needle guide 20 is disposed at a middle position of the first section 11 in the width direction. The medical fixing retractor provided with the three fixing needle guide seats 20 is not limited to three kirschner wires, but one or two kirschner wires can be selectively driven according to the setting position of the medical fixing retractor and the specific condition of a patient. When one kirschner wire is driven, the fixing pin guide 20 located in the middle is selected, and when two kirschner wires are driven, the two fixing pin guides 20 located at both ends are selected. Namely, the medical fixing retractor provided with the three fixing needle guide seats 20 can flexibly select the number of the kirschner wires to be driven and the driving position in the operation, thereby more flexibly meeting the requirements of the operation.
Optionally, the side of the first section 11 and the second section 12 forming an angle smaller than 180 ° is the inner side of the retractor body 10, and the side of the first section 11 and the second section 12 forming an angle larger than 180 ° is the outer side of the retractor body 10; the fixing needle guide seat 20 is arranged on the outer side of the retractor body 10.
