Description
Technical Field
[0001] The invention belongs to the technical field of medical devices, and in particular relates to a surgical auxiliary positioning system. Background Art
[0002] At present, surgery is required to treat many diseases. Since there are many patients who need surgery, the workload of medical staff is heavy and the intensity is high. In addition, many structures of the human body are symmetrical. Therefore, due to the negligence of medical staff, patients who should have surgery on one side are operated on the other side, which leads to major medical accidents.
[0003] Although reports of such accidents are common in recent years, there is no good solution to avoid the occurrence of accidents. Therefore, we propose a surgical auxiliary positioning system to solve this problem. Summary of the invention
[0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a surgical auxiliary positioning system, aiming to solve the problem of medical accidents caused by neglecting the left and right body positions and surgical positions.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] The central control system includes a central processing unit 21, an information synchronization memory 24, an information acquisition memory 22 and a positioning commander 23; the information synchronization memory 24 is connected to the film reader 14 through signals to receive and store the patient's body information II read by the film reader 14; the information acquisition memory 22 is connected to the camera 11 through signals to receive and store the patient's body information I acquired by the camera 11; the central processing unit 21 is connected to the information synchronization memory 24 and the information acquisition memory 22 through signals respectively to compare the patient's body information I with the patient's body information II; the central processing unit 21 is connected to the positioning commander 23 through signals to issue action instructions to the positioning commander 23 when the patient's body information I is consistent with the patient's body information II; the positioning commander 23 is connected to the electric pan-tilt head 13 and the laser positioning device 12 through signals respectively to issue rotation instructions and laser beam emission instructions to the electric pan-tilt head 13 and the laser positioning device 12 respectively.
[0008] Among them, the patient's body information I includes facial information, height information, back information and left and right position information; the patient's body information II includes surgical position information and left and right position information.
[0009] During actual operation, the film reader 14 transmits the patient's body information II to the information synchronization memory 24, which is a hard disk memory for storing the patient's body information II of the current patient; and the acquisition information memory 22 is used to store the patient's body information I acquired by the camera 11; the central processing unit 21 reads the patient's body information I and the patient's body information II from the two memories and compares them to identify whether the current patient's body position is supine or prone, and then identify the patient's left and right sides; if the body position is correct, the surgical position is calculated in combination with the body length information, and then an instruction is issued to the positioning commander 23. After the positioning commander 23 instructs the electric pan-tilt head 13 and the laser positioning device 12 to reach a suitable position, the laser positioning device 12 emits a laser beam to the left and right sides of the body and the surgical hand position, thereby specifying the surgical position for reference by medical staff, thereby reducing the possibility of medical accidents caused by incorrect body position and left and right identification errors.
[0010] Furthermore, the laser positioning device 12 includes a surgical position laser locator 121, a first body position laser locator 122 and a second body position laser locator 123; the surgical position laser locator 121, the first body position laser locator 122 and the second body position laser locator 123 are all installed on the electric pan-tilt head 13, the surgical position laser locator 121 is used to mark the patient's surgical position, and the first body position laser locator 122 and the second body position laser locator 123 are respectively used to mark the left and right directions of the patient's body.
[0011] When the system is running, the laser emitting heads of the first body position laser locator 122 and the second body position laser locator 123 are provided with the words "left" and "right", so that when activated, laser beams with the words "left" and "right" can be emitted to the left and right sides of the patient according to the patient's body position; the surgical position laser locator 121 emits a point-shaped laser beam to the surgical position. It is used as a reference for medical staff, thereby further reducing the possibility of medical accidents caused by incorrect body position and incorrect left and right identification.
[0012] Furthermore, the central control system also includes a buzzer alarm 15, which is connected to the central processor 21 through a signal, and is used to receive an alarm instruction issued by the central processor 21 and emit an alarm sound when the patient's physical information I and the patient's physical information II are inconsistent.
[0013] When the system is running, the central processor 21 reads the patient's body information I and the patient's body information II from the two memories and compares them. If the current patient's supine or prone position is inconsistent with the direction of surgery, a command is sent to the buzzer alarm 15, and the buzzer alarm 15 sounds, thereby reminding medical staff and further reducing the possibility of medical accidents caused by incorrect body position and left-right identification errors.
[0014] Furthermore, it also includes a diagnosis and treatment information prompting device, which includes the information synchronization memory 24 and an LCD display screen; the information synchronization memory 24 is connected to the diagnosis and treatment information system through signals to read the patient's diagnosis and treatment information; the central processor 21 is connected to the information synchronization memory 24 to read and filter patient information; the LCD display screen is connected to the central processor 21 through signals to receive and display patient information. This makes it convenient for medical staff to understand the current patient's diagnosis and treatment information at any time, and further reduces the possibility of medical accidents caused by incorrect body position and left and right identification errors. As a further optimization, key diagnosis and treatment information can be prompted in special fonts, such as keywords of past medical history, surgical history, allergy history, etc. Common ones include vascular malformations, thrombolytic surgery, allergies, etc.
[0015] Furthermore, it also includes a position adjustment device, which includes a displacement commander, a positioning rail 31, a driver 33 and a track car 32; the positioning rail 31 is arranged above the operating bed 1, and the positioning rail 31 is two parallel I-beams, and the grooves of the I-beams are arranged oppositely; the length direction of the positioning rail 31 is the same as the length direction of the operating bed 1; the track car 32 is overall flat, and its width is adapted to the distance between the bottoms of the grooves of the two I-beams, and a plurality of pairs of rollers 321 are installed on both sides of the track car 32, which are used to To roll in the groove of the I-beam; the driver 33 is a cylinder, the fixed end of which is installed with one end of the positioning guide rail 31, and is telescopically connected to the track car 32 to drive the track car 32 to move along the positioning track; the displacement commander is connected to the central processing unit 21 through a signal to receive the displacement command issued by the central processing unit 21, and the driver 33 is wired to the displacement commander to receive the displacement command and adjust the position; the shadow positioning system is installed at the lower part of the track car 32 to facilitate position adjustment.
[0016] By adding a position adjustment device, the position of the imaging positioning system can be adjusted at any time, and the surgical position and the left and right sides can be more accurately marked, further reducing the possibility of medical accidents caused by incorrect body position and left and right identification errors. The reason for using I-beams is that this product is a relatively mature profile with stable performance and built-in grooves. The limit can be achieved by inserting the roller 321 into the groove, and the position of the rail car 32 can be accurately adjusted by the cylinder, thereby achieving precise position adjustment.
[0017] Of course, aluminum profiles or aluminum alloy profiles with grooves can also be used according to actual conditions.

[0020] This is a flexible design for different positioning rails 31. When the positioning rail 31 adopts a single rail, since the grooves are located on both sides of the positioning rail 31, the rail car 32 should be designed below the positioning rail 31, and multiple pairs of rollers 321 are inserted into the grooves on both sides of the positioning rail 31, so that the rail car 32 can slide while being ensured. The multiple pairs of rollers 321 are inserted into the grooves on both sides of the positioning rail 31, so as to achieve the effect of hanging the rail car 32 below the positioning rail. This design is simpler than the double-rail structure.
[0021] Compared with the existing technology, the present invention has the following beneficial effects:
[0022] 1. The present invention compares the patient's body information through the central processor to determine the body position, and then projects the surgical position and the left and right directions of the body through a laser beam, which can reduce the probability of medical staff manually judging the left and right and surgical position, thereby reducing the possibility of medical accidents caused by incorrect body position and left and right identification errors.
[0023] 2. The implementation of the present invention only requires mature electronic devices such as cameras, memory, laser transmitters and central processing units, with high hardware reliability and controllable costs, which is conducive to promotion and implementation.
[0024] 3. The present invention is provided with a buzzer alarm, which can make a sound when the body position is wrong, and can effectively reduce the possibility of medical accidents caused by wrong body position and wrong left and right identification.
[0025] 4. The present invention designs a diagnosis and treatment information prompt device, which is convenient for medical staff to understand the current diagnosis and treatment information of the patient at any time, and further reduces the possibility of medical accidents caused by incorrect body position and left-right identification errors.
