Description

Technical Field

[0001] This invention relates to the field of medical technology, specifically to a tactile recognition device for ventricular puncture localization of the external auditory canal. Background Technology

[0002] During ventriculoperitoneal puncture, the surgical drape covers the patient's head, obscuring the crucial external auditory canal reference point. Sometimes, the drape is layered multiple times, making it difficult for medical staff to quickly and accurately locate this reference point visually or tactilely. Current technology lacks specialized tools for locating the external auditory canal under the surgical drape, making the pre-puncture positioning process cumbersome and time-consuming. This not only affects surgical efficiency but may also increase surgical risks due to positioning errors. Furthermore, traditional positioning methods may suffer from issues such as unstable device fixation, poor adaptability to different patients' ear contours, and interference with draping or patient discomfort during the procedure, failing to meet the requirements for precise, efficient, and stable positioning during surgery. Summary of the Invention

[0003] The purpose of this invention is to provide a tactile recognition device for external auditory canal positioning for ventricular puncture in order to solve the above-mentioned problems and overcome the defects of the prior art, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a tactile recognition device for ventricular puncture positioning of the external auditory canal, including an ear hook, an ear pressure member flexibly connected to the ear hook, a magnetic ear clamping structure for holding the ear between the ear pressure member and the ear hook, and a tactile positioning recognition component on the ear pressure member that can lift the cover for tactile recognition by extending it.

[0005] Preferably, the ear clip has an L-shaped outline, one end of the ear clip is connected to the ear hook via a first flexible connecting band, and the other end of the ear clip is connected to the tactile positioning and recognition component.

[0006] Preferably, the tactile positioning and recognition component includes a fixing sleeve, on which an earplug body is fixedly mounted. One end of the earplug body forms an ear-shaped bulb, and the other end of the earplug body has a storage cavity. A pressure plate is provided at the port of the storage cavity, and a telescopic drive structure for driving the pressure plate to move is provided inside the earplug body.

[0007] Preferably, the telescopic drive structure includes an airbag disposed in the storage cavity, and the pressure plate is fixedly disposed on the airbag.

[0008] Preferably, the touch plate is equipped with a passive infrared sensor capable of sensing and detecting the human body.

[0009] Preferably, the magnetic clip ear structure includes a fixed base, which is connected to a fixed sleeve via a second flexible connecting strip. A magnetic block is fixedly provided on the fixed base, and a magnetic plate is provided on the ear piece that magnetically engages with the magnetic block.

[0010] Preferably, the telescopic drive structure includes an air pump disposed on the inner end face of the storage cavity, a plurality of ventilation holes are provided on the outer side wall of the earbud body near the air pump, a partition is provided between the air pump and the air bag, the air inlet of the air pump passes through the partition and is connected to the storage cavity, and a battery is disposed in the earbud body.

[0011] Preferably, the telescopic drive structure includes an inflation / deflation connector connected to a fixed sleeve, one end of which is detachably connected to an air duct, and the other end of which is provided with a pressurized balloon.

[0012] Preferably, the telescopic drive structure includes an electric push rod disposed in the earbud body, the push rod head end of which is connected to the touch plate.

[0013] A method for tactile recognition of the external auditory canal during ventricular puncture localization includes the following steps: S1: Hang the ear hook on the outside of the patient's target ear, adjust the position of the ear pressure piece, and slowly insert the ball end of the ear plug in the tactile positioning and recognition component into the patient's external auditory canal. Make the magnetic block in the magnetic ear clip structure magnetically attached to the magnetic plate on the ear hook. The device is stably clamped on the ear by the magnetic force to ensure that the ear plug does not fall off. S2: When the surgical drape is placed on the patient, the pressure plate is in a retracted state, which can avoid affecting the spreading of the surgical drape. At the same time, the passive infrared sensor on the pressure plate is activated, which puts it into human body detection mode and covers the surgical drape. S3: When a medical staff member's hand is 0-5cm above the patient's head, a passive infrared sensor can detect the approaching hand and control the telescopic drive structure to extend the pressure plate and lift the surgical cover. After observing the raised position, the medical staff can use touch recognition to accurately locate the ventricular puncture reference point corresponding to the external auditory canal.

[0014] The beneficial effects are: 1. Through the tactile positioning and recognition component, when the external auditory canal is covered by a surgical drape, the pressure plate can extend and lift the surgical drape to intuitively mark the corresponding puncture reference point in the external auditory canal, solving the positioning problem caused by the drape covering, greatly improving the accuracy and efficiency of puncture reference point positioning, and reducing the risk of surgical positioning deviation. 2. The device is stably clamped to the ear using a magnetic ear clip structure. Combined with the flexible adjustment characteristics of the first and second flexible connecting straps, it can ensure that the device will not fall off during the operation, adapt to the ear contours of different patients, flexibly adjust the position to fit the external auditory canal, improve the wearing fit, and is easy to disassemble after positioning. 3. The pressure plate is initially in a retracted state and will not affect the normal unfolding of the surgical drape; the telescopic drive structure provides three modes: automatic air pump drive, manual balloon drive, and electric push rod drive, which can adapt to the needs of different surgical scenarios. It is simple to operate and does not interfere with the surgical field of vision, and medical staff can quickly get started using it. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] See Figures 1-6 As shown, this invention provides a tactile recognition device for external auditory canal positioning during ventriculoperitoneal puncture. It achieves rapid positioning of the external auditory canal corresponding to the puncture reference point under the surgical cover through magnetic clamping and infrared sensor-triggered extension / retraction. Figures 1-6 As shown, the device mainly includes an ear hook 1, an ear presser 101, a magnetic ear clip structure 3, and a tactile positioning and recognition component 2. The components work together to meet the requirements of accuracy and stability in surgical positioning.

[0020] The ear hook 1 is used to hang and fix on the outside of the patient's auricle. It is flexibly connected to the ear pressure piece 101 through the first flexible connecting strap 102, so that the ear pressure piece 101 can be flexibly adjusted according to the contour of the patient's ear to adapt to different ear structures. It is also easy to bend at an angle to facilitate the hanging of the ear hook 1. When adapting to different ear contours, the position of the tactile positioning and recognition component 2 can be finely adjusted. The ear pressure piece 101 is designed with an L-shaped outline. This structure not only facilitates the clamping of the ear with the ear hook 1, but also provides stable installation support for the tactile positioning and recognition component 2. The end of it away from the first flexible connecting strap 102 is fixedly connected to the tactile positioning and recognition component 2 to ensure the installation stability of the positioning component.

[0021] To further improve the fixation of the device on the patient's ear and prevent it from falling off during surgery due to changes in patient position or manipulation, a magnetic ear-clamping structure 3 is provided between the ear-pressing component 101 and the ear-hook component 1. This magnetic ear-clamping structure 3 includes a fixing base 301, which is connected to the fixing sleeve 201 of the tactile positioning and recognition component 2 via a second flexible connecting strap 103, ensuring that the fixing base 301 can move synchronously with the position adjustment of the ear-pressing component 101. A magnetic block 302 is fixedly mounted on the fixing base 301. Correspondingly, a magnetic plate 303 adapted to the magnetic block 302 is provided on the ear-hook component 1. Through the magnetic attraction between the magnetic block 302 and the magnetic plate 303, the device can be stably clamped on the patient's ear, balancing fixation reliability and wearing comfort.

[0022] The tactile positioning and recognition component 2 is the core component for locating the puncture reference point. It includes a fixing sleeve 201, which is fixedly connected to the ear pressure member 101. An earplug 204 is fixedly fitted onto the fixing sleeve 201. The earplug 204 is made of a soft material, such as medical-grade silicone. One end of the earplug 204 is designed as a smooth ball end, which reduces irritation to the patient's external auditory canal during insertion, improving wearing comfort and facilitating precise placement into the external auditory canal. The other end of the earplug 204 has a receiving cavity 205. A pressure plate 202 is movably mounted at the port of the receiving cavity 205. The earplug 204 contains a telescopic drive structure for driving the pressure plate 202 to move axially along the receiving cavity 205. Furthermore, to achieve automatic triggering of the pressure plate 202's telescopic movement, a passive infrared sensor 203 is installed on the pressure plate 202. This sensor can sense the approaching human body, such as a medical staff member's hand, and provide feedback signals to control the telescopic drive structure.

[0023] The following detailed description of the specific implementation of the telescopic drive structure, with reference to specific embodiments, is provided: Example 1: Automatic Air Pump Drive Mode like Figures 1-4 As shown, in this embodiment, the telescopic drive structure adopts an automatic air pump drive method to achieve automated telescopic control of the pressure plate 202. Specifically, an air pump 207 is fixedly installed on the inner end face of the storage cavity 205, and a battery 209 is also embedded inside the earplug body 204. The battery 209 is electrically connected to the air pump 207 and the passive infrared sensor 203, providing independent power supply for the entire electronic system and ensuring that the device can work stably without an external power source in surgical scenarios.

[0024] To achieve power transmission between the air pump 207 and the pressure plate 202, an airbag 208 is provided inside the receiving cavity 205 outside the air pump 207. The pressure plate 202 is fixedly mounted on the outer end face of the airbag 208 by adhesive or snap-fit, so that the expansion and contraction of the airbag 208 can directly drive the pressure plate 202 to move axially along the receiving cavity 205. At the same time, an annular partition 206 is provided between the air pump 207 and the airbag 208. This partition 206 can limit the airbag 208 to prevent it from over-inflating and deviating to one side, and can also separate the air pump 207 from the airbag 208 to reduce the squeezing effect of the airbag 208 on the air pump 207. The air pump 207's inflation port passes through the central through-hole of the partition 206 and connects to the interior of the receiving cavity 205, allowing the compressed gas output by the air pump 207 during operation to directly inflate the airbag 208, pushing the airbag 208 to expand axially, thereby causing the pressure plate 202 to extend outward from the receiving cavity 205; when contraction is required, the air pump 207 reverses the airflow, the airbag 208 contracts under its own elasticity, and the pressure plate 202 retracts into the receiving cavity 205. Figure 6As shown, the airbag 208 is folded in an S-shape inside the storage cavity 205, and its length after inflation is greater than 5cm.

[0025] In addition, several vent holes 210 are evenly provided on the outer wall of the earbud body 204 near the air pump 207. The design of the vent holes 210 has a dual function: first, it can balance the air pressure inside the storage cavity 205 and the outside, avoid the air pressure difference generated during the air pump 207's inflation and deflation process, and ensure the smooth movement of the pressure plate 202; second, it can serve as a heat dissipation channel for the air pump 207, dissipating the heat generated during the air pump's operation in a timely manner, extending the service life of the air pump 207, and avoiding malfunctions caused by overheating.

[0026] Example 2: Manual drive mode of the inflatable balloon like Figure 5 As shown, the core difference between this embodiment and Embodiment 1 is that the telescopic drive structure adopts a manual pressurization method, which is suitable for scenarios where electronic components are not desired, or where there is strict control over equipment costs. Specifically, this embodiment omits the air pump 207 and battery 209, and instead provides an inflation / deflation connector 211 on the side wall of the fixed sleeve 201. One end of the inflation / deflation connector 211 is connected to the airbag 208 in the storage cavity 205, and the other end is detachably connected to one end of the air guide tube 212. The other end of the air guide tube 212 is fixedly connected to a pressurization balloon 213, which is made of medical rubber material and has good elasticity and sealing performance.

[0027] In use, when the surgical drape needs to be lifted to determine the touch recognition position, medical personnel can manually squeeze the inflation balloon 213 to inject gas into the balloon 208 through the air delivery tube 212 and the inflation / deflation connector 211. This causes the balloon 208 to inflate, pulling the pressure plate 202 out and lifting the surgical drape. Once positioning is complete, medical personnel can press the pressure relief valve on the inflation / deflation connector 211 to release the gas in the balloon 208. The pressure plate 202 then retracts into the receiving cavity 205 under its own weight and the balloon's contraction force. The advantages of this embodiment are its simple structure, absence of electronic components, extremely low failure rate, and lower cost. Furthermore, the length of the air delivery tube 212 can be flexibly adjusted, facilitating pressure control by medical personnel outside the surgical area and avoiding interference with the surgical field of vision.

[0028] Example 3: Electric linear actuator drive mode like Figure 6 As shown, in this embodiment, the telescopic drive structure adopts an electric push rod drive method. Specifically, a miniature electric push rod 214 is fixedly installed in the storage cavity 205. The axis of the electric push rod 214 coincides with the axis of the storage cavity 205, and its push rod head is fixedly connected to the center of the inner end face of the pressure plate 202, so as to ensure that the telescopic action of the push rod can be accurately transmitted to the pressure plate 202.

[0029] A small power module (not shown) is housed within the earpiece body 204. This power module can be powered by a rechargeable battery or a disposable lithium battery, and is electrically connected to the electric actuator 214 and the passive infrared sensor 203. Alternatively, it can be powered by an external power source. When the passive infrared sensor 203 detects a medical professional's hand approaching, it sends an electrical signal to the control module of the electric actuator 214. The control module then drives the actuator 214 to extend its rod along a preset stroke, causing the pressure plate 202 to extend outwards from the receiving cavity 205. Once extended, the medical professional can touch the raised area for positioning. The electric actuator 214 offers faster response times and eliminates the risk of gas leakage during operation, resulting in higher stability.

[0030] It should be noted that, except for the telescopic drive structure, the structure, connection method, and function of the core components such as the ear hook 1, ear pressing component 101, magnetic ear clip structure 3, and passive infrared sensor 203 are consistent in the three embodiments above. Different usage requirements and scenarios can be adapted simply by replacing the telescopic drive structure. All three embodiments can realize the tactile recognition positioning process, effectively solving the problem of difficulty in identifying the external auditory canal reference point due to surgical cover obstruction in the prior art, and improving the positioning efficiency and accuracy of ventriculoperitoneal puncture surgery.

[0031] A method for tactile recognition of the external auditory canal during ventricular puncture localization includes the following steps: The ear hook 1 is hung on the outer side of the patient's target ear. The position of the ear pressure piece 101 is adjusted, and the bulbous end of the earplug 204 in the tactile positioning and recognition component 2 is slowly inserted into the patient's external auditory canal. The magnetic block 302 in the magnetic ear clip structure 3 is magnetically attracted to the magnetic plate 303 on the ear hook 1, and the device is stably clamped on the ear by the magnetic attraction force, ensuring that the earplug 204 does not fall off. When the surgical drape is placed on the patient, the pressure plate 202 is in a retracted state, which can avoid affecting the unfolding of the surgical drape. Simultaneously, the passive infrared sensor 203 on the pressure plate 202 is activated, putting it into human body detection mode and covering the surgical drape. When the medical staff's hand is 0-5cm above the patient's head, the passive infrared sensor 203 can sense the approaching hand and control the telescopic drive structure to extend the pressure plate 202 and lift the surgical drape. After observing the raised position, the medical staff can use touch recognition to accurately locate the ventricular puncture reference point corresponding to the external auditory canal.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
