The terms "inner" and "outer" are used to refer to directions toward and away from, respectively, the geometric center of a particular component.
As a first aspect of the present invention, there is provided a capsule compression-type puncture instrument, as shown in fig. 1 to 4, comprising: the puncture cannula 100 is hollow inside the puncture cannula 100 to form a puncture cannula cavity 110, one end of the puncture cannula cavity 110 is in a horn shape, the puncture needle core 200 can penetrate through the puncture cannula cavity 110 to enter puncture tissues, and the puncture needle core 200 can be taken out under the condition that the puncture cannula 100 is not pulled out after puncture is finished.
The puncture cannula 100 is provided with scale marks, the front end of the puncture cannula 100 is coated with a capsule 300, the capsule 300 is connected with a fluid injection device, and the fluid injection device is used for injecting gas and liquid into the capsule 300; specifically, the balloon 300 is wrapped at the front end of the outer wall of the puncture cannula 100, and the balloon 300 is inflated when being inflated with fluid and deflated when being evacuated; in order to make the end of the capsule 300 be expanded more fully when the capsule 300 is expanded, the supporting strip 310 is attached to the inner wall of the end of the capsule 300, the supporting strip 310 is arranged at the end of the capsule 300 in an umbrella shape and spaced from each other, and can be opened and closed along with the expansion and contraction of the capsule, and the puncture sleeve 100 corresponding to the supporting strip 310 is provided with supporting strip grooves, which can make the outer diameter of the puncture sleeve 100 not be changed when the capsule 300 is folded, so as to avoid increasing the puncture resistance. The puncture cannula 100 near the rear end of the capsule 300 is provided with a compression cover plate 120, the inner hole of the compression cover plate 120 is provided with threads which are matched with the threads at the rear part of the puncture cannula 100, and the compression cover plate 120 can move back and forth on the puncture cannula 100 through rotation, so that the compression force is adjusted, and the capsule can be protected from being punctured accidentally.
And the compression cover plate 120 and the umbrella-shaped support bars 310 can support the end of the bladder 300 when the end is expanded, so that the end of the bladder 300 is fully expanded to generate compression force to the chest wall. It can be understood that, when the puncture outfit is punctured in place, the capsule 300 is inflated with fluid to make the capsule 300 expand in a dumbbell shape, the expansion of the capsule 300 in the puncture hole is limited by the compression of the tissues around the chest wall hole, the capsule 300 at the two ends of the needle hole expands and bulges, and the internal and external pressing forces are enhanced by the pressing action of the umbrella-shaped support bars 310 and the cover plate 120; therefore, once intercostal artery rupture bleeding or tension pneumothorax occurs in the chest puncture operation, the bag body 300 can be expanded to press hemostasis and establish a closed drainage channel (without suture fixation) in time by a minimally invasive method at the first time to perform thoracic gas drainage so as to solve the risk brought to the patient along with the thoracic gas drainage.
Since the needle holes may generate a flow restriction effect on the flow of the injected gas or liquid in the balloon 300, in order to enable the fluid injection device to uniformly fill all positions of the balloon 300 and reduce the flow restriction effect of the needle holes, the fluid injection device includes an injection tube 410 disposed at the rear end portion of the puncture cannula 100; an injection channel is arranged in the wall of the puncture cannula 100, an outlet 420 and an inlet are respectively arranged at the front end and the rear end of the injection channel, the inlet is connected with one end of the injection tube 410, the outlet 420 is communicated with the inner cavity of the balloon 300, and the outlets 420 are arranged at intervals in the area of the puncture cannula 100 coated by the balloon 300, so that the problem of uneven expansion of the balloon 300 caused by uneven local injection of fluid in the balloon 300 can be avoided; and the injection channel is bifurcated and comprises sub-channels which are in one-to-one correspondence with the outlets 420, the sub-channels are all connected with one end of the trunk line, and the injection pipe 410 is connected with the other end of the trunk line.
In order to prevent puncturing the visceral pleura of the lung during puncturing, when the device is used for puncturing the parietal pleura during puncturing the chest wall (with a breakthrough feeling), the puncturing core is immediately withdrawn to reach the position of the groove, a movable hole 130 is formed in the tube wall of the rear end part of the puncturing sleeve 100, and an elastic limiting device 140 is arranged in the movable hole 130;
the elastic limiting device 140 comprises a limiting rod 150, the limiting rod 150 comprises a limiting head 151 and a limiting tail 152, a limiting pressing sheet 153 is arranged between the limiting head 151 and the limiting tail 152, a return spring 160 is arranged between the limiting pressing sheet 153 and the movable hole 130, and the tail end of the limiting tail 152 is exposed out of one side of the movable hole;
the puncture needle core 200 is provided with a limit groove 170 which is matched with the limit head 151 of the limit rod 150. When the puncture needle core 200 is unscrewed and retreated to the position, corresponding to the movable hole 130, of the limiting groove 170 on the puncture needle core 200, under the elastic force of the return spring 160, the limiting head 151 of the limiting rod 150 is bounced into the limiting groove 170 of the puncture needle core 200, so that the movement of the puncture needle core 200 is limited; when the puncture needle core 200 needs to be taken out, the limiting tail 152 of the limiting rod 150 is firstly pulled up, so that the return spring 160 is compressed by the limiting pressing sheet 153, the limiting head 151 of the limiting rod 150 leaves the limiting groove 170, and the puncture needle core 200 is in a removable state.
As a second aspect of the present invention, there is provided a thoracic gas drainage assembly for use in thoracocentesis procedures or clinical emergency treatment of spontaneous tension pneumothorax, which facilitates thoracic gas drainage to avoid the risk to the patient associated therewith.
