Problems solved by technology

[0003] At present, minimally invasive surgery mainly uses endoscopy, which is displayed on the monitor for doctors to observe. During observation, doctors need to constantly move their eyes at the surgical site and the monitor bracket, which affects the continuity of the operation and is prone to fatigue. In view of the above shortcomings, some researches The latter adopts the patient's body surface projection method based on augmented reality technology (Augmented Reality AR), and uses a projector to project the image captured by the endoscope on the patient's body surface, so as to assist the doctor's judgment when necessary and form a virtual epidermal transparency effect; but When doctors need large-scale observation or local observation, assistants are needed to assist in holding and adjusting body surface projection images, which affects the continuity of surgery. Therefore, it is urgent to provide doctors with an adjustment device for minimally invasive surgery body surface projection. question

specific Embodiment approach 1

[0071] An adjustment device for body surface projection in minimally invasive surgery disclosed in this embodiment, combined with figure 1 As shown, it includes: a thigh pad 1, a calf pad 2, a foot pad 3, a base 4, a first angle sensor 5 and a second angle sensor 6, the upper end of the base 4 is provided with a supporting structure, and the supporting structure is Rods are used for support. The support structure is connected with the thigh pad 1. The thigh pad is used to provide support for the doctor's thigh. The thigh pad 1 is set horizontally, the calf pad 2 is vertically set, and one end of the thigh pad 1 It is hinged with the upper end of the calf pad 2, and the hinged rotatable surface is the first rotating surface including the length direction of the thigh pad 1 and the calf pad 2. After the doctor puts the thigh on the thigh pad, the calf It can drive the calf support plate 3 to swing in front of or to the back of the doctor. The lower end of the calf support plate ...

specific Embodiment approach 2

[0078] This embodiment is based on the specific implementation mode 1, specifically, in combination with figure 2 , the thigh pad 1 includes: a buttock support section 1-1, a thigh support section 1-2 and a first push rod 1-3, the support surface of the buttock support section 1-1 is arranged horizontally, and the thigh support section The support surface of 1-2 is arranged obliquely, and the lower end of the buttock support section 1-1 is hingedly connected with the support structure, the rotation surface of the hinge connection is parallel to the first rotation surface, and the first push rod 1-3 One end is hingedly connected to the support structure, and the other end of the first push rod 1-3 is hingedly connected to the lower surface of the thigh support section 1-2;

[0079] The buttock support section 1-1 supports the doctor's buttocks, and the end of the thigh support section 1-2 away from the hip support section 1-1 is inclined downward. When in use, the thigh suppor...

specific Embodiment approach 3

[0081] This embodiment is based on the specific implementation mode 1, specifically, in combination with figure 2 As shown, the calf pad 2 includes: an upper connection section 2-1, a lower connection section 2-2 and a second push rod 2-3, and the lower end of the upper connection section 2-1 passes along the upper connection section 2- 1 The sliding structure provided in the length direction is connected to the lower connecting section 2-2, the lower end of the lower connecting section 2-2 is provided with a horizontal section perpendicular to the length direction of the upper connecting section 2-1, and the upper surface of the horizontal section is in contact with the foot pad The plate 3 is rotationally connected, one end of the second push rod 2-3 is connected to the upper connection section 2-1, and the other end of the second push rod 2-3 is connected to the lower connection section 2-2;

[0082] The upper connecting section 2-1 and the lower connecting section 2-2 ena...

Abstract

The invention belongs to the technical field of body surface projection adjusting and action capturing, and particularly relates to an adjusting device for minimally invasive surgery body surface projection. The adjusting device comprises a thigh subplate, a shank subplate, a foot subplate, a first angle sensor and a second angle sensor, one end of the thigh subplate is hinged to the upper end ofthe shank subplate, the lower end of the shank subplate is rotatably connected with the foot subplate, the first angle sensor is arranged at a joint of the thigh subplate and the shank subplate, and the second angle sensor is arranged at a position where the shank subplate and the foot subplate are in rotating connection. When a doctor conducts a minimally invasive surgery, two rotating angle messages are acquired through the two angle sensors and taken as coordinate values to adjust a projection image, so that the doctor does not need an assistant for handholding and adjusting; only shanks and feet need to be moved during adjusting, so that impact on surgical continuity caused by impact on hand operation of the doctor is avoided, and impact on the surgery caused by the image adjusting process is avoided.

Description

technical field [0001] The invention belongs to the technical fields of body surface projection adjustment and motion capture, and in particular relates to an adjustment device for minimally invasive surgery body surface projection. Background technique [0002] Compared with traditional open surgery, minimally invasive surgery has the advantages of small wound, light pain, and fast healing, which caters to the aesthetics of modern people, so it has attracted more and more attention and is used in some abdominal and cranial surgery; [0003] At present, minimally invasive surgery mainly uses endoscopy, which is displayed on the monitor for doctors to observe. During observation, doctors need to constantly move their eyes at the surgical site and the monitor bracket, which affects the continuity of the operation and is prone to fatigue. In view of the above shortcomings, some researches The latter adopts the patient's body surface projection method based on augmented reality ...
