Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a abdominal puncture and deflation device. Background Art

[0002] Endoscopic submucosal dissection (ESD) takes a long time to operate, has a high incidence of intraoperative bleeding and perforation, and requires high technical skills from the operator. Band ligation is required after perforation occurs, but patients are prone to pneumoperitoneum after band ligation. At this time, abdominal puncture and deflation with a 20ml syringe is required. Pneumoperitoneum can cause subcutaneous emphysema, hypercapnia and acidosis, gas embolism, pneumothorax, mediastinal emphysema and other serious complications. Therefore, stable and effective abdominal puncture and deflation are extremely important for the treatment of pneumoperitoneum and avoiding the above complications.

[0003] At present, in the prior art, the operator usually clamps the rubber tube behind the puncture needle with a hemostatic forceps. The operator fixes the skin at the puncture site with his left hand, holds the puncture needle with his right hand, and passes through the anesthesia site vertically and then tilts 45° to 60° to enter 1-2 cm, and then vertically pierces the peritoneum. When the resistance of the needle tip suddenly disappears, it means that the needle tip has passed through the peritoneal wall layer, and the air can be extracted and deflated. During the extraction and deflation process, the puncture needle needs to be continuously clamped to maintain the puncture state, and the pressing force needs to be increased slowly and steadily. The operator can press with the assistance of the operator's hand or by gradually tightening the multi-head bandage pre-selected and tied to the abdomen, so that after the abdominal cavity is vented, the internal abdominal pressure can be maintained by applying external pressure to avoid the phenomenon of excessive change of abdominal pressure leading to expansion of visceral blood vessels and blood pressure drop or even shock.

[0004] At present, in the existing technology, after the operator manually inserts the puncture needle, the operator is required to clamp the needle with a hemostatic forceps to keep it inserted. Then, the operator is required to maintain this posture throughout the subsequent long exhaust phase. Maintaining this posture requires holding the hemostatic clamp for a long time and ensuring that it does not shake, which will cause great discomfort to the operator. In addition, the abdomen needs to be continuously and steadily pressurized during this process. During the long-term pressing process, the operator is prone to uneven force application, resulting in excessive pressing and injuring the patient, or interfering with the puncture needle and causing damage to the puncture site. In addition, the operator needs to perform vacuum multiple times during the pressing and exhaust process, and the operation is very complicated. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose an abdominal puncture and deflation device, which solves the problem in the prior art that there is a lack of a structure that can stably limit the puncture needle for puncture and deflation, which requires the operator to hold and fix it for a long time, causing the operator to be very tired and easily make mistakes due to fatigue and damage the puncture site. Due to the lack of a structure that can stably and continuously press the patient's abdominal cavity, the pressing force is unstable, causing drastic changes in abdominal pressure and damaging the patient's organs. Due to the lack of a structure that can stably and regularly cooperate with compression to automatically pump and exhaust, the manual pumping and exhaust operation is complicated and inefficient.

[0033] like Figure 1-8 As shown, an embodiment of the present invention is: an abdominal puncture deflation device, including a pressure-sensitive abdominal fixation belt 1, an abdominal puncture operation cavity 2 is opened in the middle of the pressure-sensitive abdominal fixation belt, wherein the abdominal puncture operation cavity includes an annular fixing seat 3 fixedly arranged in the middle of the pressure-sensitive abdominal fixation belt, a rotating support platform 4 is fixedly arranged on both sides of the annular fixing seat, a limit clamping hole 5 and a rotating guide hole 6 are arranged at the upper end of the rotating support platform, a middle insertion connection hole 7 is fixedly arranged in the middle of the rotating support platform, and a rotating locking plate 29 is an arc plate, wherein one end of the arc plate is a rotating shaft end 8, and a rotating guide hole 6 is fixedly arranged at the top of the rotating shaft end. The guide insertion rod 9 cooperates with the hole, and the rotating shaft end is coaxial with the rotating support platform and rotates around it. The other end of the arc plate is a limit locking end 10, and the end of the limit locking end is fitted with the surface of the rotating support platform. A middle insertion connector 11 that cooperates with the middle insertion connecting hole is fixedly arranged in the middle of the end of the limit locking end. A limit insertion hole 12 corresponding to the limit hole is opened at the upper end of the limit locking end. The limit hole and the limit insertion hole are inserted and connected and fixed by a limit insertion key 13, thereby realizing secondary limit fixation after the middle insertion connector is inserted into the middle insertion connecting hole, so that the rotating locking plate can be firmly limited after rotation and locking.

[0034] One end of the rotating locking plate is rotatably connected to the rotating support platform, and the other end thereof is fixedly provided with a puncture needle limiting sleeve 14, which includes two identical puncture needle limiting half sleeves 15, which are fixedly connected to the middle part of the arc plate through a connecting column 16, and the puncture needle limiting half sleeve includes a pipeline limiting sleeve 17, a needle limiting sleeve 18 is fixedly provided at the lower end of the pipeline limiting sleeve, an overflow liquid adsorption chamber 19 is provided at the bottom of the needle limiting sleeve, and an adsorption sponge 20 is fixedly provided on the inner wall of the overflow liquid adsorption chamber.

[0035] A constant speed air suction and gas collecting machine 22 is arranged at the upper end of the puncture needle limiting sleeve through an electric lifting frame 21, and the lower end of the electric lifting frame is fixedly arranged at the upper end of the rotating support platform, and an air suction machine fixing hole 23 is arranged in the middle of the electric lifting frame, and the constant speed air suction and gas collecting machine is fixedly arranged in the air suction machine fixing hole, and an electromagnetic connection valve 24 is fixedly arranged at the bottom of the constant speed air suction and gas collecting machine for connecting the rubber hose for abdominal vacuuming, and a pressing connecting rod 25 is fixedly arranged on both sides of the electric lifting frame, and a flexible abdominal pressing bag 26 is fixedly arranged at the bottom of the pressing connecting rod, and the constant pressure abdominal presser is composed of a pressing connecting rod and a flexible abdominal pressing bag. A central controller 27 is arranged on the outside of the pressure-sensitive abdominal fixation belt, and the central controller is connected to the puncture needle limiting sleeve, the constant speed air suction and gas collecting machine and the constant pressure abdominal presser through lines.

[0036] When implementing this embodiment, first align the abdominal puncture operation cavity with the patient's puncture site, then wrap the pressure-sensitive abdominal fixation belt around the patient's abdomen, and connect and fix the pressure-sensitive abdominal fixation belt through a constant-speed rolling machine. After completing the wearing that is firmly and fittingly fitted, disinfect the inside of the abdominal puncture operation cavity, and then the medical staff will make a preliminary mark on the patient's body part with the puncture needle limiting sleeve when it is closed. After completing the preliminary puncture on the patient, the puncture needle limiting sleeve will be loosened to expose the skin below. The medical staff will first perform a preliminary puncture on the marked part of the patient. After the puncture is completed, the rotating shaft end of the rotating locking plate is rotated around the rotating support platform so that the puncture needle limiting half sleeves fit each other to form a limit for the puncture needle. At this time, the middle insertion connector is inserted into the middle insertion connection hole to complete the preliminary limit. The medical staff only needs to insert the limit insertion key into the limit clamp hole and the limit insertion hole to complete the complete locking of the rotating locking plate. At this time, the puncture needle limiting sleeve will form a limit to the puncture needle to complete its limited support. Then, the exhaust pipe above the puncture needle is connected to the electromagnetic connection valve of the constant-speed vacuum gas collecting machine, and the exhaust operation can be started. In order to prevent the flexible abdominal compression bag from interfering with the rotating locking plate when the rotating locking plate rotates, the flexible abdominal compression bag is initially moved away from the rotating locking plate below by controlling the electric lifting frame. However, when assembling the exhaust pipe and the electromagnetic connection valve of the constant-speed vacuum gas collecting machine, the flexible abdominal compression bag is lowered to fit the patient's abdominal cavity by lowering the electric lifting frame. Then, while the puncture needle is fixed to exhaust, the electric lifting frame is controlled to make the flexible abdominal compression bag perform flexibly and constantly press downward. The pressure sensing membrane on the bottom surface of the flexible abdominal compression bag and the inner surface of the pressure-sensitive abdominal fixation belt senses the pressure and adjusts it in time to prevent the patient's intra-abdominal pressure from changing drastically.

[0037] The present embodiment provides an abdominal puncture and deflation device that simultaneously has a puncture needle limiting and fixing structure, a stable abdominal compression structure, and an automatic cyclic vacuuming and exhaust structure. Two identical puncture needle limiting half-sleeves are used to rotate and clamp the puncture needle inserted into the patient's body to limit the position, which is conducive to convenient, fast and stable limiting and fixing of the puncture needle. An electric lifting frame is used to drive a compression bag to press the patient's abdominal cavity, which is conducive to providing continuous and stable abdominal compression pressure. A constant-speed vacuuming and gas collecting machine is installed above the fixed puncture needle, which is conducive to realizing the constant-speed automatic extraction of intra-abdominal gas, thereby reducing the operating burden of medical personnel, improving the efficiency of vacuuming and exhaust operations, ensuring the stability of the abdominal compression pressure, and improving the safety of abdominal compression and exhaust.

[0038] In this embodiment, pressure sensing membranes are fixedly provided on the bottom surface of the flexible abdominal compression bag and the inner surface of the pressure-sensitive abdominal fixation belt, which is conducive to accurately sensing the pressure value and accurately controlling the pressing force.

[0039] In this embodiment, a constant-speed roller 28 for rolling and releasing the pressure-sensitive abdominal fixation belt at a constant speed is provided at one end of the pressure-sensitive abdominal fixation belt, which is conducive to tightening and relaxing the pressure-sensitive abdominal fixation belt by rolling the pressure-sensitive abdominal fixation belt, thereby conveniently adjusting the pressing force.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
