Problems solved by technology

Generally speaking, other surgical instruments for minimally invasive surgery need to enter the human body through a puncture device, but when the electric knife in the puncture device burns or electrocoagulates human tissue, it will generate a lot of smoke and water vapor, which may damage the body on the one hand. The physical and mental health of medical staff, on the other hand, can easily affect the sight of medical staff
In order to overcome this problem, the applicant has proposed a puncture device with the function of circulating smoke exhaust. Its structure and working principle can refer to CN109498122B, but when the puncture device is used in clinical medicine, the field of view of the endoscope is Partially, there is a big limitation for the doctor in the operation, and it is easy to cause unnecessary damage to the tissue of the non-treatment part of the patient, so it still needs to be improved

Embodiment 1

[0032] see Figure 1-Figure 5 The basic structure of a circulating filter puncture device with a lens assembly provided in this embodiment can refer to the puncture device of CN109498122B, that is, it also includes a puncture rod 1 and a sheath tube assembly 2 sleeved on the outside of the puncture rod. The sheath tube assembly includes an outer tube 21 and an inner tube 22 . The outer tube is sleeved on the outside of the inner tube to form an interlayer. The interlayer is distributed with an air intake channel 6 and a smoke exhaust channel 7 isolated from each other by a partition 8 . The air inlet channel 6 communicates the air inlet with the air outlet 211 , the air inlet is arranged at the head of the outer tube 21 , and the air outlet 211 is arranged at the thin end of the outer tube 21 . The smoke exhaust passage 7 communicates the smoke outlet with the smoke outlet, the smoke outlet is arranged at the thin end of the inner pipe 22 , and the smoke outlet is arranged at ...

Embodiment 2

[0047] The circulating filter piercer with lens assembly provided in this embodiment is further improved on the basis of the piercer in Embodiment 1. The improvements are as follows: please refer to Figure 6-Figure 7 , a plurality of air injection holes 44 are formed on the lens carrier plate 4 , preferably, these air injection holes 44 are distributed around the lens 3 , the air injection holes are communicated with the air inlet channel 6 , and the air jet direction of each air injection hole is directed to the surface of the lens 3 . Wherein, by setting the aperture of the air jet hole 44 to be smaller, for example, about 1 mm or even smaller, a larger jet air flow velocity can be obtained (the air flow direction is such as Image 6 The slanted arrow in the ), so that the surface of the lens 3 can be kept purging, and a clear view can always be obtained without the need for additional cleaning mechanisms. Preferably, a self-cleaning coating or the like may also be provided...

Abstract

The circulating filtering puncture outfit comprises a puncture rod, a sheath tube assembly arranged on the outer side of the puncture rod in a sleeving mode and the lens assembly, the sheath tube assembly comprises an outer tube and an inner tube, the outer tube is arranged on the outer side of the inner tube in a sleeving mode to form an interlayer, and an air inlet channel and a smoke exhaust channel which are isolated from each other are distributed in the interlayer; the lens assembly comprises a lens and a lens carrier plate, the lens is fixedly installed on the outer side face of the lens carrier plate, the lens carrier plate is movably embedded in the outer tube and can move back and forth in the circumferential direction of the outer tube, and the lens carrier plate is in sealing fit with the outer tube through a dynamic sealing structure. According to the circulating filtration puncture outfit, the lens assembly is additionally arranged on the circulating filtration puncture outfit, so that a doctor can visually observe the condition in the abdominal cavity in real time in clinical medical treatment, the surgical operation is more accurate, and accidental injury to tissues of non-treatment parts of a patient is avoided.

Description

technical field [0001] The invention relates to a puncture device, in particular to a circulating filter puncture device with a lens assembly, which belongs to the technical field of medical equipment. Background technique [0002] At present, endoscopic minimally invasive surgery represented by laparoscopic surgery has been widely used in gynecology, general surgery and other operations. Generally speaking, other surgical instruments for minimally invasive surgery need to enter the human body through the trocar, but when the electrocautery in the trocar cauterizes or coagulates human tissue, a large amount of smoke and water vapor will be generated, which may damage the human body on the one hand. The physical and mental health of medical staff, on the other hand, easily affects the sight of medical staff. In order to overcome this problem, the applicant has proposed a puncture device with a function of circulating smoke exhaust. Its structure and working principle can ref...
