Description

Technical Field

[0001] The present invention relates to a puncture device, in particular to a puncture device for abdominal surgery of gastrointestinal surgery. Background Art

[0002] Abdominal puncture is a technique in which a needle is inserted through the abdominal wall into the peritoneal cavity to extract ascites or inject drugs to assist in the diagnosis or treatment of diseases.

[0003] Existing abdominal wall puncture devices do not have the function of prompting the puncturist whether the puncture is successful. When in use, the puncture needle is inserted vertically and enters the abdominal cavity when the resistance disappears; after drawing out the fluid, the needle is slowly withdrawn or a tube is placed for drainage. It is necessary to rely on the user's experience to judge whether the puncture is successful. If the needle is continued to be inserted, it may cause damage to the intestines or blood vessels. For novices, it is relatively difficult to perform unskilled abdominal wall puncture on the human body and to judge whether the puncture is successful based on feeling, which also increases the relative risk of damage to abdominal organs. Summary of the Invention

[0004] The purpose of the present invention is to provide a gastrointestinal surgery abdominal cavity puncture device to solve the existing problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a gastrointestinal surgical abdominal cavity puncture device, comprising an extrusion seat and a puncture needle, wherein adjustment arms are symmetrically fixed on both sides of the extrusion seat, a limiting slide groove is provided under the adjustment arm, a limiting slider is slidably installed in the limiting slide groove, a support arm is clamped under the limiting slider, a clamping block is fixed to the other end of the support arm, a pressure sensor is fixed on the top of the extrusion seat, and a handle is fixed on the pressure sensor.

[0006] Preferably, a bidirectional threaded shaft is rotatably installed in the extrusion seat and the adjustment arm, and a knob is fixedly connected to one end of the bidirectional threaded shaft.

[0007] Preferably, a threaded sleeve is embedded in the limiting sliding block, and the threaded sleeve is threadedly matched with the bidirectional threaded shaft.

[0008] Preferably, a V-shaped groove is provided on one side of the clamping block, and the V-shaped groove cooperates with the puncture needle.

[0014] Preferably, a connection slot is provided at the upper end of the support arm, and the connection block is clamped in the connection slot.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By using a pressure sensor to detect the force applied during puncture, when the puncture needle penetrates the parietal peritoneum and enters the abdominal cavity, the resistance is significantly reduced. The pressure sensor will send a signal to the control board, which will then send a signal to the speaker to generate a voice message, alerting the operator to continue inserting the needle.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-5 As shown, the present invention has the following specific embodiments.

[0022] Example 1 A gastrointestinal surgical abdominal cavity puncture device includes an extrusion seat 1 and a puncture needle 9. Adjustment arms 101 are symmetrically fixed on both sides of the extrusion seat 1. A limiting slide groove 102 is provided under the adjusting arm 101. A limiting slider 4 is slidably installed in the limiting slide groove 102. A support arm 5 is clamped under the limiting slider 4. A clamping block 6 is fixed to the other end of the support arm 5. A pressure sensor 3 is fixed on the top of the extrusion seat 1, and a handle 2 is fixed on the pressure sensor 3.

[0023] In this embodiment, the limiting slider 4 is slidably installed inside the limiting slide groove 102, and the support arm 5 is clamped under the limiting slider 4, so that the movement of the limiting slider 4 can drive the support arm 5 to move, and the movement of the support arm 5 can drive the clamping block 6 to move, and the distance between the two clamping blocks 6 is adjusted. The clamping block 6 is used to clamp and fix the puncture needle 9, which can be used to clamp and fix puncture needles 9 of different specifications and thicknesses. The puncture needle 9 is clamped and fixed under the squeezing seat 1. The operator needs to hold the handle 2, and the pressure sensor 3 is connected between the handle 2 and the squeezing seat 1. Holding the handle 2 controls the clamped puncture needle 9 to perform abdominal puncture operation, and the puncture needle passes through in sequence. When penetrating the skin, subcutaneous fat, anterior rectus sheath and muscle layer, it is necessary to overcome the friction and elastic resistance generated by the dense tissue structure. At this time, the force applied by holding the handle 2 is finally transmitted to the puncture needle 9 through the pressure sensor 3. The pressure sensor 3 will detect the applied thrust. The resistance peak usually occurs at the moment of penetrating the rectus sheath or fascia layer. When the puncture needle penetrates the parietal peritoneum and enters the abdominal cavity, the resistance is significantly reduced to close to zero resistance. At this time, the thrust received by the pressure sensor 3 will be reduced instantaneously. After the detected pressure suddenly drops, the pressure sensor 3 will send a signal to remind the operator to avoid the operator continuing to insert the needle and causing damage to the intestine or blood vessels.

[0024] Example 2 A bidirectional threaded shaft 103 is rotatably installed in the extrusion seat 1 and the adjusting arm 101, and a knob 104 is fixed to one end of the bidirectional threaded shaft 103. A threaded sleeve 401 is embedded in the limiting slider 4, and the threaded sleeve 401 is threadedly matched with the bidirectional threaded shaft 103. A V-shaped groove 601 is provided on one side of the clamping block 6, and the V-shaped groove 601 cooperates with the puncture needle 9.

[0025] In this embodiment, the bidirectional threaded shaft 103 can be driven to rotate by the knob 104, and the bidirectional threaded shaft 103 is threadedly matched with the threaded sleeve 401, and then the rotation of the bidirectional threaded shaft 103 can drive the limit slider 4 to move, and the movement of the limit slider 4 can drive the support arm 5, and the V-groove 601 cooperates with the puncture needle 9. The V-groove 601 is used to clamp the puncture needle 9 at the center to avoid the problem of sliding and dislocation of the puncture needle 9 after being subjected to force.

[0026] Example 3 A built-in battery 203 is fixedly connected to the handle 2, and a control mainboard 204 is fixedly connected to the handle 2 and below the built-in battery 203. An interactive panel 201 is embedded in the upper end of the handle 2, and the interactive panel 201 is electrically connected to the control mainboard 204. A number of speakers 202 are embedded around the handle 2, and the speakers 202 are electrically connected to the control mainboard 204. The pressure sensor 3 is electrically connected to the control mainboard 204. A connecting block 402 is fixedly connected to the bottom of the limit slider 4, and a connecting slot 501 is provided at the upper end of the support arm 5, and the connecting block 402 is snapped into the connecting slot 501.

[0027] In this embodiment, the interactive panel 201 can be used to adjust the alarm threshold of the instantaneous pressure drop according to the operator's wishes to avoid the pressure drop alarm range being too low, which leads to the problem of continuous false alarms during the puncture process. After the pressure sensor 3 detects the instantaneous drop in the conducted pressure, it will send a signal to the control motherboard 204, and the control motherboard 204 will send a voice signal to the speaker 202. The speaker 202 will issue a voice warning, and the connecting card block 402 and the connecting card slot 501 will cooperate with each other to clamp the support arm 5 under the limit slider 4. The support arm 5 and the clamping block 6 can be removed directly and separately at a later stage to facilitate disinfection and cleaning.

[0028] The working principle and usage process of the present invention are as follows: the puncture needle 9 is placed between the two clamping blocks 6, and the two-way threaded shaft 103 is rotated to drive the two clamping blocks 6 to approach each other. The puncture needle 9 is clamped and fixed under the squeezing seat 1 by the clamping block 6. The grip 2 is held to control the clamped puncture needle 9 to perform abdominal puncture operation. When the puncture needle passes through the skin, subcutaneous fat, anterior sheath of the rectus abdominis and muscle layer in turn, it is necessary to overcome the friction and elastic resistance generated by the dense tissue structure. At this time, the force applied by holding the grip 2 is finally transmitted to the puncture needle 9 through the pressure sensor 3. The pressure sensor 3 will detect the applied thrust. When the puncture needle penetrates the parietal peritoneum and enters the abdominal cavity, the resistance is significantly reduced. The pressure sensor 3 will send a signal to the control main board 204, and the control main board 204 is used to send a signal to the speaker 202 to generate a voice message to alert the operator to continue inserting.

[0029] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
