Description

Technical Field

[0001] The present invention belongs to the technical field of puncture devices, and particularly relates to a visualization puncture device based on wireless transmission and its usage method. Background Art

[0002] Puncture operation is an important clinical examination and clinical treatment means, which is of great significance for disease diagnosis and treatment. The commonly used puncture components in clinics usually consist of a puncture needle and a puncture cannula. During puncture, the puncture needle is inserted into the puncture cannula, and after puncturing to the predetermined position, the puncture needle is withdrawn, and then clinical operations are carried out.

[0003] In some abdominal surgeries, it may be necessary to connect a pneumoperitoneum machine after puncture to establish an artificial pneumoperitoneum through the pneumoperitoneum machine. The mechanical pressurized inflation of the pneumoperitoneum machine separates the abdominal wall from the viscera, providing enough operating space for the surgery. However, the traditional puncture method cannot observe the puncture depth, cannot ensure the safety of the puncture process, and also cannot observe the pneumoperitoneum effect on the abdominal cavity, increasing the safety hazards during the surgery; if the endoscope is inserted into the puncture cannula for observation after withdrawing the puncture needle, it is difficult to ensure the stability of the endoscope, greatly increasing the operation difficulty of medical staff, and still difficult to observe the puncture depth in real time.

The puncture needle assembly 3 includes a handle housing 301. The handle housing 301 is connected to the conversion cap through a second buckle 303. A puncture needle tube 302 adapted to the puncture cannula 102 is provided below the handle housing 301. A first through hole 201 for passing through the puncture needle tube 302 is provided in the middle of the conversion cap. A camera lens 305 is provided inside the lower part of the puncture needle tube 302. The camera lens 305 is connected to a PCB board 306, and the PCB board 306 is connected to a wireless signal transceiver 307. This design can realize the real-time transmission of the camera image during the puncture process through the cooperation of the puncture needle assembly 3, the conversion cap assembly 2, and the puncture cannula assembly 1, that is, it can conveniently observe the puncture depth and ensure the safety of the puncture process. Moreover, during abdominal cavity surgery that requires the establishment of an artificial pneumoperitoneum, the inflation effect of the abdominal cavity can be observed, thus reducing the potential safety hazards during the operation.

[0038] To ensure the shooting effect of the camera lens 305, the puncture cannula 102 and the puncture needle tube 302 are made of transparent materials.

[0039] The PCB board 306 is connected to a gyroscope. During the puncture process, it can reduce the tilting or shaking of the image caused by the operator rotating or accidentally touching the visualization puncture device, etc., to ensure the stability of the image transmission.

[0040] A visual component installation tube 304 is provided inside the puncture needle tube 302. The camera lens 305 is arranged inside the lower part of the visual component installation tube 304, the PCB board 306 is arranged inside the visual component installation tube 304, the PCB board 306 is connected to a button switch 308, a pressing column 309 is provided above the button switch 308, the lower part of the pressing column 309 is arranged inside the visual component installation tube 304, and a first opening for exposing the upper part of the pressing column 309 is provided in the upper part of the handle housing 301. Thus, with the help of the visual component installation tube 304, components such as the camera lens 305, the PCB board 306, and the button switch 308 can be conveniently installed and fixed, and the pressing column 309 is used as the power-on button to trigger the button switch 308.

[0041] The PCB board 306 is connected to a battery 310. The battery 310 is arranged inside the visual component installation tube 304, so as to provide electrical energy for components such as the PCB board 306. Moreover, the battery 310 can be a rechargeable battery.

[0042] The wireless signal transceiver 307 is arranged on the PCB board 306 and inside the visual component installation tube 304. A data transmission interface 311 is also arranged on the PCB board 306 to ensure the signal transmission effect, and an opening exposing the data transmission interface 311 is provided on the side wall of the visual component installation tube 304. The wireless signal transceiver 307 can adopt one of a Bluetooth module, a 4G module, a 5G module, and a WiFi module.

[0043] Specifically, the visual component installation tube 304 includes a left installation semi-circular tube and a right installation semi-circular tube adapted to the left installation semi-circular tube. First embedding grooves for fixing the battery 310 are provided on the inner walls of the left installation semi-circular tube and the right installation semi-circular tube, and second embedding grooves for fixing the camera lens 305 are provided below the first embedding grooves, thereby improving the installation stability of components such as the camera lens 305 and the battery 310.

[0044] Block-shaped protrusions are provided on both sides of the lower part of the pressing column 309, and limiting grooves 312 adapted to the block-shaped protrusions are provided on both sides of the upper part of the visual component installation tube 304; moreover, the length of the limiting groove 312 is greater than the thickness of the block-shaped protrusion, so that when the block-shaped protrusions on both sides of the lower part of the pressing column 309 are located in the limiting groove 312, the moving distance of the pressing column 309 in the vertical direction can be limited, ensuring the triggering effect of the pressing column 309 on the button switch 308.

[0045] The second buckle 303 includes an elastic member made of an elastic material. The cross-section of the elastic member is semi-circular. A second opening for passing through the pressing column 309 is provided in the middle of the elastic member. First withdrawal buttons in the shape of flakes are connected to both sides of the elastic member. Third openings for exposing the withdrawal buttons are provided on both side walls of the handle shell 301; a first flake-shaped body is provided below the withdrawal button, a first strip-shaped protrusion is provided on the outer side of the lower part of the first flake-shaped body, first insertion grooves 211 for inserting the first flake-shaped body are provided on both sides of the upper part of the conversion cap, and a first card slot adapted to the first strip-shaped protrusion is provided on the inner wall of the first insertion groove 211. Thus, when the user presses the elastic member inward at the first withdrawal buttons on both sides, so that the first strip-shaped protrusion disengages from the first card slot, the first flake-shaped body can be pulled out from the first insertion groove 211, and then the handle shell 301 and the conversion cap can be disassembled, so that the puncture needle tube 302 is separated from the puncture cannula 102, forming an instrument channel, facilitating other clinical operations with the puncture cannula 102. And, in order to facilitate pressing the first withdrawal button, first anti-slip lines are provided on the outer side surface of the first withdrawal button.

[0046] The conversion cap includes an upper cover 202 and a lower cover 203 of the conversion cap. The upper cover 202 of the conversion cap is arranged above the lower cover 203 of the conversion cap, and an installation cavity is formed between the upper cover 202 and the lower cover 203 of the conversion cap. A sealing valve upper fixing ring 206, a sealing valve 207, a sealing valve lower fixing ring 208, a gas blocking valve pressing ring 209, and a gas blocking valve 210 are successively arranged in the installation cavity from top to bottom. Thus, through the cooperation of components such as the sealing valve 207 and the gas blocking valve 210, the sealing and gas blocking effects are achieved, avoiding situations such as air leakage after the puncture needle tube 302 is pulled out, thereby ensuring the safety of abdominal surgery. To facilitate the fixed installation of the sealing valve 207 and the gas blocking valve 210, a stepped structure protruding inwards is provided on the inner wall of the first through hole 201. The stepped structure is annular and located inside the lower cover 203 of the conversion cap. The sealing valve upper fixing ring 206, the sealing valve 207, the sealing valve lower fixing ring 208, the gas blocking valve pressing ring 209, and the gas blocking valve 210 are all arranged above the stepped structure. Several first fixing columns extending downwards are provided at the lower part of the sealing valve upper fixing ring 206. The sealing valve 207 is provided with first insertion holes adapted to the first fixing columns. Several second fixing columns extending upwards are provided at the upper part of the sealing valve lower fixing ring 208. The sealing valve 207 is provided with second insertion holes adapted to the second fixing columns. Several third fixing columns extending downwards are provided at the lower part of the gas blocking valve pressing ring 209. The gas blocking valve 210 is provided with a second through hole for passing through the third fixing columns, and the stepped structure is provided with third insertion holes adapted to the third fixing columns.

[0047] An installation hole is provided on a side wall of the conversion cap near the gas injection interface 204. The gas injection switch 205 includes a lever and a columnar body. The lever is connected to the upper part of the columnar body. The lower part of the columnar body is inserted into the installation hole, and a third through hole for communicating with the gas injection interface 204 is provided at the lower part of the columnar body. A fourth through hole corresponding to the position of the gas injection interface 204 is provided on the inner wall of the installation hole. The fourth through hole communicates with the first through hole 201, and the third through hole is located below the gas blocking valve 210. When the laparoscopic surgery is over, the user can rotate the lever, and the lever drives the columnar body to rotate, so that both sides of the third through hole at the lower part of the columnar body communicate with the gas injection interface 204 and the fourth through hole respectively. Thus, the successively communicated gas injection interface 204, third through hole, fourth through hole, and first through hole 201 form a passage, facilitating the release of abdominal cavity gas. When there is no need to release the abdominal cavity gas, just rotate the lever, and the lever drives the columnar body to rotate, so that the third through hole is disconnected from the gas injection interface 204 and the fourth through hole, and the sealing and gas blocking states of the puncture cannula 102 can be maintained.

[0048] The lower part of the conversion cap is sleeved on the outer side of the upper part of the puncture cannula 102, and a sealing ring 104 is provided at the connection between the conversion cap and the puncture cannula 102 to ensure the sealing effect at the connection between the conversion cap and the puncture cannula 102. To facilitate the installation of the sealing ring 104, an annular groove for clamping the sealing ring 104 is provided on the upper part of the puncture cannula 102.

[0049] The first buckle 103 includes two second sheet bodies made of elastic material. The two second sheet bodies are respectively arranged on both sides of the sleeve base 101. A second withdrawal button is connected to the outer side of the second sheet body. A second strip-shaped protrusion is provided on the outer side of the upper part of the second sheet body. Second insertion grooves for inserting the upper parts of the second sheet bodies are provided on both sides of the lower part of the conversion cap. Second card slots adapted to the second strip-shaped protrusions are provided on the inner walls of the second insertion grooves. Thus, when the user presses the second withdrawal buttons on both sides of the sleeve base 101 inward, so that the second strip-shaped protrusions disengage from the second card slots, the second sheet bodies can be pulled out from the second insertion grooves, and then the sleeve base 101 and the conversion cap can be disassembled, facilitating the replacement of the conversion cap and other clinical operations. And, in order to facilitate pressing the second withdrawal buttons, second anti-slip lines are provided on the outer side surfaces of the second withdrawal buttons.

[0050] Embodiment 2

[0051] A usage method of a visualization puncture device based on wireless transmission includes:

[0052] S1: Insert a puncture needle of the same specification into a puncture cannula of the same specification; by long pressing the button switch, trigger the wireless signal transceiver to send a puncture device start signal to an external receiving end; squeeze the tip of the puncture needle into the patient's abdominal cavity;

[0053] S2: After the external receiving end receives the puncture device start signal, receive the internal image of the puncture site acquired by the camera and present it to the visualization interface of the external receiving end;

[0054] S3: By short pressing the button switch, trigger the wireless signal transceiver to send a puncture completion signal to the external receiving end, open the puncture device gas injection valve, completely release the abdominal cavity gas, then pull out the puncture needle, remove the puncture cannula, and suture each puncture opening.

[0055] In this embodiment, the external receiving end is a mobile terminal application. The mobile terminal application connects to the puncture device through WI FI, encodes the real-time video stream acquired by the camera and wirelessly transmits it to the external receiving end; the external receiving end decodes the received video stream through a decoder, so as to display the internal image of the puncture site in real time. The user can clearly see the puncture process and the condition inside the abdominal cavity by observing the visualization interface on the external receiving end, so as to make accurate judgments and operations.

[0056] The functions of the visualization interface also include screenshot, video recording, and real-time data display, etc., to meet the diverse needs of doctors during the operation. The screenshot function can capture key pictures, which is convenient for postoperative analysis and discussion; the video recording function can completely save the entire puncture process, providing valuable materials for medical teaching and research.

[0057] The specific implementation process is as follows:

[0058] By directly outputting video frames using SurfaceView (Android) or Metal (iOS), high frame rate display is ensured. The mobile terminal application overlays the puncture path, depth markers, and sensor data (such as pressure / temperature) on the video screen and realizes dynamic drawing through Canvas or Shader;

[0059] The mobile terminal application grabs Bitmap (Android) or CVPixelBuffer (iOS) from the current video frame buffer and saves it as a PNG / JPG file; encodes the decoded frames into an MP4 file through MediaMuxer (Android) or AVFoundation (iOS), supporting segmented storage and timestamp marking.

[0060] Specifically, the video display area of the mobile terminal application and the video stream data obtained by the camera are synchronously compensated through a timing dynamic compensation method, including:

[0061] S1: When collecting each frame of video, a high-precision hardware clock is used to generate the acquisition timestamp T c ; embed the timestamp and the current device clock T d during encoding; transmit the encoded frames and associated sensor data through WiFi, ensuring that the data packets contain the same timestamp;

[0062] S2: After the wireless connection is established, the mobile terminal and the camera terminal exchange the initial timestamp through an NTP-like mechanism, and calculate the clock offset Δ = T m - T d ; convert the timestamp T c of the subsequent frames to the mobile terminal time: T c ’ = T c + Δ; periodically update Δ through T d in the data packets to compensate for clock drift;

[0063] S3: Perform dynamic buffer management. Through a priority queue, store the decoded frames according to the mobile terminal time T c ’ , and the queue length adapts to the network condition; calculate the data delay D t = T r - T c ’ of a single frame at the mobile terminal, where Tr is the timestamp at the receiving end; calculate the average delay D a of the sliding window and the jitter J = max(Dt ) - min(D t );

[0064] Set the buffer depth according to the average delay and jitter;

[0065] If continuous frame drops occur in the video stream displayed on the visualization interface, increase the buffer depth;

[0066] S4: Set the display time of the predicted frame, the predicted frame T display = T c ’ + B, where B is the buffer depth;

[0067] When the VSync signal of the Android / iOS display subsystem (SurfaceView / Metal) arrives, select the predicted frame T that is less than the arrival time of the VSync signal display for rendering the latest frame; if the frame is not ready, repeat the previous frame.

[0068] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
