Embodiment Construction

[0041] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0042] Such as Figure 1-Figure 5 As shown, a retractor for brain surgery includes a frame 1 , a drive mechanism 2 and a retractor mechanism 3 . The frame 1 is used to be fixed on the ground or on the patient's operating table.

[0043] Specifically, such as figure 1 with figure 2 As shown, the driving mechanism 2 includes a motor 21 , a stepped plate 22 , a first rack 23 , a second rack 24 , a driving gear 25 and a driven gear 26 . The motor 21 is fixedly mounted on the frame 1 , and the step plate 22 is slidably mounted on the frame 1 along the radial direction of the rotating shaft 46 of the motor 21 .

Abstract

The invention relates to the technical field of retractors, in particular to a retractor for brain surgery, including a frame, a driving mechanism and a retractor. The driving mechanism includes a motor, a stepped plate, a first rack, a second rack, a driving gear and a driven gear, and the motor is fixedly installed on the frame; the first rack is slidably installed on the stepped plate, and the second The rack is fixedly installed on the step plate, the driving gear is fixedly connected with the rotating shaft of the motor, the driven gear is rotatably installed on the step plate on one side of the driving gear, and the bottom of the driven gear is connected to the step plate. The second rack is engaged; the retracting mechanism includes a first retracting part and a second retracting part, the first retracting part is installed on one end of the first rack, and the second retracting part can It is disassembled and installed at one end of the step plate. The purpose of the present invention is to solve the problem that surgical wounds need to be retracted one by one, resulting in cumbersome operation and long operation time.

Description

technical field [0001] The invention relates to the technical field of retractors, in particular to a retractor for brain surgery. Background technique [0002] Retractors, also known as retractors, are used to retract tissues and reveal the scope of surgery for easy exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. [0003] At present, when brain surgery is performed, manual flexible shaft retractors are widely used for retraction. The existing flexible shaft retractors are mainly composed of a ring and a retracting part that is slidably connected to the ring to retract the incision. constitute. [0004] Since the wounds of different surgical patients have different shapes, medical staff need to retract them into circular, rectangular or other irregular shapes. However, when the existing manual retractor is used, it is necessary to move the retracting parts one by one to adjust a suitable wound. The operation is ...
