Embodiment 1

[0031] The thoracoscopic pleural friction device of this embodiment includes a friction head and a handle, the friction head includes a brush head 11 and bristles 12, the bristles 12 are attached to the brush head 11, and the brush head 11 also includes Connecting head 13, the connecting head 13 of the brush head 11 is connected with one end of the handle, the brush head 11 is provided with a drive motor 14, and the output end of the drive motor 14 is provided with an eccentric member 15.

[0032] The eccentric member 15 in this embodiment refers to a disc, an eccentric wheel, a cam or a crankshaft with eccentric protrusions on its side.

[0033] The handle of the present embodiment is also connected with a power cord 24, through which an external power supply is used to supply power to the drive motor 14 of the pleural friction device under thoracoscope of the present invention, and the power cord 24 stretches out from the tail of the handle away from the end of the friction h...

Embodiment 2

[0036] On the basis of Embodiment 1, the thoracoscopic pleural friction device of this embodiment further includes a friction force regulator, and the friction force regulator is arranged on the handle or connected with the thoracoscopic pleural friction device by wires.

[0037] The friction force regulator in the thoracoscopic pleural friction device of the present embodiment includes a governor and a control button 22. According to friction needs, the friction force can be controlled by the governor and the control button 22 on the friction force regulator. .

[0038] The governor of this embodiment uses frequency conversion to regulate the speed of the drive motor 14 .

[0039] The control button 22 in this embodiment includes at least two gears. The control button 22 can adjust the vibration amplitude of the friction head, and then adjust the friction force of the friction head. Preferably, the control button 22 in this embodiment includes three gears.

[0040] The other...

Embodiment 3

[0045] On the basis of Embodiment 1 and Embodiment 2, the handle of the thoracoscopic pleural friction device of this embodiment is also provided with an easy-bending area 21, and the easy-bending area 21 of this embodiment is arranged on the handle close to the handle and the handle. The position of the joint of the friction head, the easy-bending area 21 constitutes a part of the handle, and the easy-bending area 21 in this embodiment is selected as a metal hose.

[0046]When the thoracoscopic pleural friction device of this embodiment is used, on the basis of the use methods of Embodiment 1 and Embodiment 2, the angle of the friction head and the handle can be changed by bending the metal hose, and with the assistance of the thoracoscope, The thoracoscopic pleural friction device of this embodiment can reach every corner of the chest cavity.

Abstract

The invention discloses a pleura friction device under a thoracoscope. The pleura friction device under the thoracoscope comprises a friction head and a handle. The friction head comprises a brushing head and bristles. The bristles are adhered to the brushing head. The brushing head comprises a connection head, the connection head of the brushing head is connected with one end of the handle, and a drive motor for driving the brushing head to vibrate is arranged in the brushing head or the handle. The output end of the drive motor is provided with an eccentric part. The pleura friction device under the thoracoscope further comprises a friction intensity regulator which is arranged on the handle or is connected with the pleura friction device under the thoracoscope through a wire. According to the pleura friction device under the thoracoscope, the friction intensity can be adjusted as needed so as to increase friction comfort. In addition, an area easily bent on the handle can change the angles of the friction head and the handle, and therefore under the assistance of the thoracoscope, the pleura friction device under the thoracoscope can reach all corners of the thoracic cavity.

Description

technical field [0001] The invention relates to a medical device, in particular to a pleural friction device under a thoracoscope. Background technique [0002] Thoracoscopic surgery (video-assisted thoracoscopic surgery) uses modern camera technology and high-tech surgical equipment to complete complex intrathoracic surgery under a chest wall cannula or tiny incision. It has changed the treatment of thoracic surgery diseases The concept, known as one of the major breakthroughs in the field of thoracic surgery in the last century, is a representative operation of minimally invasive thoracic surgery and the direction of future thoracic surgery development. [0003] To complete thoracoscopic surgery, only 1 to 3 small holes of 1.5 cm in chest wall are required. The tiny medical camera projects the situation in the chest cavity to the large display screen, which is equivalent to putting the doctor's eyes into the patient's chest cavity for surgery. The surgical field of view ...
