Description

Technical Field

[0001] This utility model belongs to the field of biomedical technology, and relates to a screw tightening force monitoring handle and a head frame installation force monitoring device, particularly to a screw tightening force monitoring handle and a head frame installation force monitoring device during X-ray surgery head frame installation. Background Technology

[0002] With the development of medical technology, radiation therapy methods such as Gamma Knife, CyberKnife, and Proton Knife have become increasingly mature and sophisticated, making them an indispensable means of treating head tumors. The principle behind these methods is to focus high-energy rays emitted from a radiation source onto the lesion tissue of the patient for diagnosis and treatment. During radiation therapy, a rigid positioning head frame needs to be installed on the patient's skull to limit the position of the head and achieve precise treatment.

[0003] During the installation of the positioning headgear, one doctor holds the headgear while another holds the installation handle, tightening the headgear onto the patient's skull with four screws. However, there is currently no standard or reference for the screw installation force, nor is there a monitoring system to track this force, creating a clinical gap in the proper application of positioning headgear installation force. This results in varying installation force between different doctors, differences in the doctor's condition, and even variations in the force applied by the doctor's left and right hands (generally, the right hand applies more force, and the left hand less). Furthermore, different installation forces are required for individual patients with varying conditions (normal bone density, osteoporosis, or those who have undergone cranioplasty, etc.).

[0004] Because there are no reference standards or monitoring systems to provide a basis for the use of positioning head frames, the current use of positioning head frames relies entirely on the doctor's extensive experience. This leads to the risk of excessive force during the installation of the positioning head frame, which could cause secondary injury to the patient. At the same time, there are no reliable means for experienced doctors to pass on their experience to new patients, making it difficult to pass on experience. Utility Model Content

[0005] The purpose of this invention is to address the deficiency in the existing technology of lacking monitoring of the fixing force of the positioning head frame, and to propose a tightening force monitoring handle and a head frame installation force monitoring device.

[0006] This utility model is achieved through the following technical solution:

[0007] In the first aspect, this utility model provides a tightening force monitoring handle, including: a tightening head 1-1 and a housing, as well as a main shaft, a strain shaft, a tightening force sensor and a main board disposed in the housing;

[0008] One end of the tightening head is used to connect to the screw, and the other end is connected to one end of the spindle. The other end of the spindle is connected to one end of the strain shaft, and the other end of the strain shaft is fixedly connected to the housing. The spindle is rotatably connected to the housing. The tightening force sensor is set on the mounting plane of the strain shaft to detect the deformation signal of the strain shaft and convert it into tightening force data, which is then transmitted to the main board. The main board is used to perform analog-to-digital conversion on the received tightening force data and transmit the converted tightening force data to an external display.

[0009] Preferably, it also includes bearings, and the spindle is rotatably connected to the housing via the bearings.

[0010] Preferably, a wireless transmission board is also provided inside the housing, through which the main board transmits the tightening force data to an external display.

[0011] Preferably, the housing includes an outer shell and a top cover connected to the outer shell.

[0012] Preferably, the housing has a battery compartment for installing batteries, which power the motherboard and the wireless transmission board.

[0013] Preferably, the external display is a computer.

[0014] Secondly, this utility model provides a head frame installation force monitoring device, including the aforementioned tightening force monitoring handle, as well as screws and a head frame; the head frame is used to be worn on the head of the patient to be treated, and the tightening force monitoring handle is used to pass the screw through the connecting hole on the head frame and tighten it onto the skull of the patient to be treated so as to fix the head frame to the skull of the patient to be treated.

[0015] Preferably, the head frame installation force monitoring device further includes a simulated head mold, on which a force block, a pressure sensor, and a display module are provided; a tightening force monitoring handle is used to pass the screw through the head frame and tighten it onto the force block; the pressure sensor is used to detect the pressure applied by the screw to the pressure block and transmit the pressure data to the display module.

[0016] Preferably, the simulated head mold is provided with a connecting block, the pressure block is installed on the connecting block, and the connecting block is installed on the pressure sensor.

[0017] Preferably, four force-bearing blocks are set up, arranged diagonally in pairs, and pressure sensors are set up one-to-one with the force-bearing blocks.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The tightening force monitoring handle provided by this utility model is equipped with a strain shaft and a tightening force sensor. The strain shaft deforms under force, causing the tightening force sensor to deform as well. The tightening force sensor detects the deformation signal of the strain shaft and converts it into tightening force data, which is then transmitted to the main board. The main board then sends the data to the display for viewing. In other words, the tightening force monitoring handle has a tightening force monitoring function. Therefore, when using this tightening force monitoring handle to tighten a screw onto an object, the tightening force data can be observed on the display. Based on the displayed tightening force data and the object's tolerance to tightening force, the operator can adjust the tightening force applied in real time, thus avoiding damage to the object due to excessive force. This tightening force monitoring handle can be applied in the installation of X-ray surgical head frames, allowing doctors to see and adjust the tightening force of their left and right hands at any time, thus avoiding injury to the patient due to excessive force. It solves the problems caused by the lack of specific numerical references for screw tightening force, resulting in different tightening forces for different screw positions, different tightening forces for the left and right hands, and different tightening forces for different doctors.

[0020] Furthermore, the spindle of this invention is rotatably connected to the housing via bearings, and the housing can provide a certain degree of support for the spindle.

[0021] Furthermore, by installing a wireless transmission board inside the casing, wireless transmission between the motherboard and the monitor can be achieved, avoiding complicated wired connections.

[0022] Furthermore, this utility model divides the housing into two parts: an outer shell and a top cover. Both parts are detachable, which facilitates the installation and replacement of various components inside the housing.

[0023] This utility model provides a head frame installation force monitoring device based on the aforementioned tightening force monitoring handle. It is applied in the installation of head frames for X-ray surgery. When installing the head frame using this device, the doctor can see the tightening force of each hand at any time and make adjustments accordingly. This can better ensure that the tightening force of each screw is reasonable, avoid excessive force that may cause injury to the patient, and also avoid insufficient force that may lead to unstable fixation, or uneven head frame arrangement due to different screw forces.

[0024] Furthermore, this utility model's headframe installation force monitoring device can be equipped with a simulated head mold, which replaces a portion of the human skull to support the headframe. A pressure sensor detects the pressure applied by the screws to the pressure block (equivalent to the pressure experienced by the patient's skull in clinical practice) and transmits the data to a display module for real-time display. This device allows observation of the tightening force and the pressure on the skull. It can be used as a teaching device for headframe installation instruction or for inexperienced doctors to practice headframe fixation, thereby improving learning efficiency. It effectively solves the problem of not being able to describe specific force values ​​during experience transfer and addresses the issue of novice doctors lacking pre-clinical training equipment and having to practice on patients. Furthermore, based on the tightening force and pressure data displayed by the headframe installation force monitoring device, the correlation between tightening force and pressure can be obtained, allowing for the setting of a reasonable preset tightening force value according to the pressure experienced by the patient's skull.

The main board 1-9 is used to perform analog-to-digital conversion on the received tightening force data and transmit the analog-to-digital converted tightening force data to the display 9.

[0042] The strain shaft 1-4 is made of an elastically deformable metal rod. Its function is to cause the tightening force sensor 1-5 to deform under force, so that the tightening force sensor 1-5 can detect the deformation signal of the strain shaft 1-4 and convert it into tightening force data, which is then transmitted to the main board 1-9. The main board 1-9 is mounted on the housing, and its function is to perform analog-to-digital conversion, zero-point correction, scaling, and other processing on the tightening force data collected by the tightening force sensor 1-5, and then send the processed tightening force data to the display 9 for display.

[0043] Therefore, when the screw is tightened onto an object using the tightening force monitoring handle of this utility model, the tightening force data can be observed on the display 9.

[0048] In some preferred embodiments of this utility model, the tightening head 1-1 has a hexagonal head at one end for connecting the screw, which connects to the hexagonal hole of the screw 2 and drives the screw 2 to rotate.

[0049] In some preferred embodiments of this utility model, a battery compartment for installing batteries 1-13 is also provided inside the outer casing 1-6. The batteries 1-13 are used to power the main board 1-9 and the wireless transmission board 1-10.

[0050] In some specific embodiments, a battery spring contact 1-11 is provided inside the battery compartment.

The battery compartment cover 1-8 is mounted on the outer casing 1-6 to facilitate battery replacement.

[0051] In some preferred embodiments of this utility model, the display 9 can be a screen mounted on the housing or an external display, such as a computer. The computer wirelessly transmits data with the tightening force monitoring handle 1, performs data calibration and zeroing operations on the tightening force monitoring handle 1, and simultaneously displays and records the tightening force value generated by the tightening force monitoring handle 1.

[0052] This utility model features a tightening force monitoring handle that can be used to tighten screws or bolts onto any object. During tightening, the tightening force data can be observed, allowing the operator to adjust the tightening force in real time. This prevents damage from excessive force or instability due to insufficient force. The main application of this utility model is in the installation of X-ray surgical head frames, enabling doctors to monitor and adjust the tightening force of both hands simultaneously, thus preventing injury to the patient from excessive force.

[0053] For details, please refer to Figures 1-5 The present invention relates to a head frame mounting force monitoring device based on a tightening force monitoring handle, comprising the tightening force monitoring handle as described above, as well as a screw 2 and a head frame 3; the head frame 3 is used to be worn on the head of the patient to be treated, and the tightening force monitoring handle is used to pass the screw 2 through the connecting hole on the head frame 3 and tighten it onto the skull of the patient to be treated so as to fix the head frame 3 to the skull of the patient to be treated.

[0054] The screws 2 are used to fix the head frame 3 to the patient's skull. A set of head frames 3 requires 4 screws for fixation. There are also 4 connection holes on the head frame 3, which are arranged diagonally in pairs.

[0055] The head frame 3 is a standard medical head frame, which is used to precisely locate the lesion target by fixing the patient's skull, thereby enabling precise treatment.

[0056] The headrest installation force monitoring device can be used to monitor the screw tightening force during headrest installation. The method of use is as follows: When the patient needs to wear the headrest 3, one doctor holds the headrest 3 in the designated position on the patient's head, and another doctor holds a tightening force monitoring handle 1 in each hand and tightens the screws 2 in symmetrical positions (from the patient's perspective, left front to right rear, right front to left rear). The tightening force of the screws 2 will be transmitted to the strain shaft 1-4 through the tightening head 1-1 and the main shaft 1-2. The tightening force sensor 1-5 detects the elastic deformation of the strain shaft 1-4, thereby obtaining the tightening force value, and transmitting the value to the main board 1-9. The main board 1-9 processes the tightening force value and sends it to the wireless transmission board 1-10. The wireless transmission board 1-10 sends the data to the computer, and the computer displays the value in the form of numbers and curves, and records and processes it. The doctor installing the head frame 3 observes the tightening force value in real time and adjusts the installation process accordingly. When the tightening force of the four screws 2 is repeatedly adjusted to reach the same preset tightening force value, the head frame is fixed.

[0057] refer to Figure 1-5 In another embodiment of the present invention, the head frame installation force monitoring device further includes a simulated head mold 4, which is provided with a force block 6, a pressure sensor 8, and a display module 5; the tightening force monitoring handle is used to tighten the screw 2 through the head frame 3 onto the force block 6; the pressure sensor 8 is used to detect the pressure applied by the screw 2 to the pressure block 6 and transmit the pressure data to the display module 5.

[0058] In this head frame installation force monitoring device, the simulated head mold 4 is the part in the teaching device that replaces the human skull and is used to support the head frame 3. The pressure block 6 is used to bear the pressure of the screw 2, and the pressure sensor 8 is used to detect the pressure applied by the screw 2 to the pressure block 6 (this pressure is equivalent to the pressure on the patient's skull in clinical practice) and transmit the data to the display module 5 for real-time display.

[0059] In some preferred embodiments of this invention, a connecting block 7 is provided on the simulated head mold 4, the pressure block 6 is mounted on the connecting block 7, and the connecting block 7 is mounted on the pressure sensor 8. Therefore, if the operator applies excessive force and damages the pressure block, the pressure block can be replaced, preventing damage to the pressure sensor 8.

[0060] Preferably, four force-bearing blocks 6 are arranged diagonally in pairs, and pressure sensors 8 are arranged one-to-one with force-bearing blocks 6. The four pressure sensors 8 monitor the pressure generated by the four screws 2 respectively.

[0061] Therefore, this headrest installation force monitoring device can be used as a teaching device for headrest installation instruction, and can be used by inexperienced doctors to practice headrest fixation operations.

[0062] Inexperienced doctors may mishandle the head frame during installation, applying excessive force (risk of skull fracture) or insufficient force (risk of positioning failure), which can directly affect treatment outcomes and even cause serious harm to the patient. Therefore, the head frame installation force monitoring device of this invention can be used for practice. When a novice doctor uses the tightening force monitoring handle 1 to install the head frame 3 onto the simulated head mold 4, the display 9 (e.g., a computer) will display and record the tightening force data of the doctor's hands in real time. Simultaneously, the display module 5 will display the pressure of the screw 2 on the simulated head mold 4 in real time. The doctor can adjust the applied force based on this tightening force and pressure data, thereby achieving the training effect.

[0063] By repeatedly training with a force monitoring device installed on the headframe, one can quickly master the installation process and the force required, thereby improving learning efficiency and effectively solving the problem that specific force values ​​cannot be described in the transmission of experience.

[0064] In addition, the relationship between tightening force and pressure can be obtained from the tightening force and pressure data displayed by the head frame installation force monitoring device, so as to set a reasonable preset value of tightening force according to the pressure borne by the patient's skull.

[0065] like Figure 9 The image shown is a picture of the actual object and data display of the head frame mounting force monitoring device in a specific embodiment of this utility model. It can be seen that the display can show the tightening force data and the display module can show the pressure data, which is very intuitive.
