Description

Technical Field

[0001] The utility model relates to the field of puncture devices, in particular to a visual puncture device. Background Art

[0002] The trocar is an important medical device, which consists of a needle with a blade and a handle. The needle enters the human tissue by operating the handle. The trocar can be used to obtain biological tissue or body fluid samples from the body surface or inside the organs for disease diagnosis and treatment. In addition, the trocar can reduce the incision during the operation, reduce the patient's postoperative pain, and achieve fast recovery, high safety and less trauma.

[0003] In actual use, doctors usually perform punctures blindly, so there is a potential risk that the sharp puncture device will accidentally puncture organs in the abdominal cavity. Although some puncture devices use a transparent rod core, allowing doctors to observe the internal conditions of the abdominal cavity through the handle end of the rod core, this method has limitations, because during the puncture process, the doctor's palm needs to hold the handle end to operate, which makes it impossible for the doctor to observe the conditions in the abdominal cavity at the same time, so there is still a risk of accidentally puncturing organs.

[0004] Therefore, in view of the above-mentioned situation that the doctor is unable to observe the condition inside the abdominal cavity when using the puncture device, resulting in the puncture device accidentally piercing the internal organs, a visual puncture device can be designed. Through pneumatic telescopic adjustment, elastic structure and camera function, the doctor can observe the condition inside the abdominal cavity at the same time as puncturing the abdominal cavity, thereby avoiding the problem of the puncture device accidentally piercing the internal organs.

The camera 601 is installed in the puncture rod 1, and enters the abdominal cavity through the puncture rod 1, so as to realize the observation of the inside of the abdominal cavity. The display screen 602 is connected to the signal interface at the upper end of the camera 601 through the wire, and receives and displays the abdominal cavity image captured by the camera 601 in real time. In this way, the doctor can intuitively understand the situation inside the abdominal cavity, which provides an important reference for the surgical operation. The lighting module includes an annular light groove 701 and an LED lamp 702; an annular light groove 701 is opened at the lower end of the protective shell of the camera 601, and the LED lamp 702 with a built-in power supply is installed in the annular light groove 701.

The light emitted by the LED lamp 702 can illuminate the inside of the abdominal cavity, provide a clear field of view for the camera 601, and help the doctor better observe the situation inside the abdominal cavity.

[0029] See also Figure 6In this embodiment, the limiting assembly includes an annular block 801 and a slot 802; the annular block 801 for fixing the puncture rod 1 is integrally fixedly connected to the lower end of the knob 2, and a slot 802 adapted to the annular block 801 is provided at the upper end of the sealing cap 3. The limiting assembly also includes a spring 803 and a limiting plate 804; one end of the spring 803 is fixedly connected to the inner wall of the puncture rod 1, and the other end is fixedly connected to the limiting plate 804. The annular block 801 is tightly fixed to the lower end of the knob 2 in an integral fixed connection manner, and the slot 802 provides a snap-fit ​​position for the annular block 801 to ensure that the annular block 801 can play its fixing role. When the annular block 801 is locked When the camera 601 is inserted into the card slot 802, the puncture rod 1 is fixed on the upper end of the sealing cap 3, thereby realizing effective position limiting of the puncture rod 1. When the camera 601 is inserted into the puncture rod 1, the camera 601 will squeeze the spring 803, and the spring 803 is compressed to provide elastic force, thereby ensuring that the camera 601 remains stable in the puncture rod 1. The limiting plate 804 is provided with a rubber pad to increase the friction with the camera 601. The puncture rod 1 is a hollow structure and a puncture head 9 is installed at the bottom. The puncture head 9 is a transparent structure. The material of the puncture rod 1 can be made of high-strength, corrosion-resistant metal or alloy material. The puncture head 9 is installed at the bottom of the puncture rod 1 and is a key component for performing the puncture operation. It adopts a transparent structure design, so that the camera 601 can clearly capture the contact between the puncture head 9 and the surrounding tissues, so that the doctor can more accurately judge the puncture depth and position. The transparent puncture head 9 is made of highly transparent medical materials, such as medical grade polycarbonate or glass, which not only have good optical properties, but also have high mechanical strength and corrosion resistance.

[0030] During operation, the doctor gently pushes the camera 601 into the puncture rod 1. At this time, the camera 601 gradually squeezes the spring 803. The spring 803 begins to contract and releases elastic force after being pressed. This elastic force helps the camera 601 to maintain a stable position in the puncture rod 1. At the same time, the rubber pad attached to the limit plate 804 begins to play a role, which increases the friction between the camera 601 and further ensures the stability of the camera 601.

[0031] Next, the doctor passes the puncture rod 1 through the sealing cap 3 and the puncture sleeve 4 in sequence. As the puncture rod 1 goes deeper, the annular block 801 on it will accurately snap into the slot 802, achieving a stable connection between the puncture rod 1 and the sealing cap 3 and the puncture sleeve 4. At this time, the doctor gently turns the knob 2 to drive the puncture head 9 to rotate so that it can accurately pierce the skin. At this time, the cylinder 501 is started. The cylinder 501 can receive the input of compressed gas and convert it into mechanical force to drive the support block 503 to move, so that the support block 503 contacts the human abdomen. At the same time, the suction cup 502 uses the negative pressure principle to be tightly adsorbed on the surface of the abdominal cavity, providing additional support and fixing force for the puncture sleeve 4;

[0032] During the entire puncture process, the doctor always pays close attention to the real-time image on the display screen 602 to ensure that the puncture head 9 will not accidentally injure the internal organs. At the same time, the LED light 702 emits bright light to provide sufficient lighting for the camera 601, enabling it to capture clear and detailed images of the internal abdominal cavity, providing the doctor with an accurate surgical field of view.

[0033] Through the above steps, through the coordinated operation of the support component, camera component, lighting module and limit component, not only the operating platform during the operation is stabilized and the clarity of the picture is guaranteed, but also the accuracy and safety of the operation are significantly improved. The camera component, with its excellent high-definition capture capability, enables the doctor to observe the surgical site in detail, and the bright lighting function of the lighting module further enhances the clarity of the surgical field and provides the doctor with a brighter and clearer surgical environment. These four components cooperate with each other to help doctors achieve more convenient and efficient surgical results, and solve the problem that the doctor cannot observe the condition in the abdominal cavity when using the puncture device, resulting in the puncture device accidentally piercing the internal organs.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
