The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It is noted that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present; when an element is referred to as being "secured" to another element, it can be directly secured to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
In one embodiment, as shown in FIGS. 1-4, a self-cleaning puncture instrument is provided, and the self-cleaning puncture instrument of this embodiment comprises a puncture cannula 1, wherein the hollow interior of the puncture cannula 1 is used as a through channel 11 for avoiding laparoscope. Usually, the laparoscope is required to be used with the puncture outfit, and during the use process, the laparoscope is punctured by the puncture outfit and then extends into the human body through the through channel 11 of the puncture outfit to work.
Because the existing laparoscope cleaning or wiping process is complicated, the self-cleaning channel 12 is arranged inside the tube wall of the puncture cannula 1 of the puncture outfit provided by the embodiment, and the nozzle 13 for communicating the through channel 11 and the self-cleaning channel 12 is arranged on the tube wall of the puncture cannula 1.
The puncture outfit of the embodiment is provided with a self-cleaning channel 12, when the laparoscope needs to be cleaned in the operation process, the required cleaning gas or liquid is directly pressed into the self-cleaning channel 12, and the gas or liquid passes through the self-cleaning channel 12 and then is sprayed to the laparoscope positioned in the through channel 11 by a spray opening 13. The laparoscope does not need to be completely taken out in the whole cleaning process, and only needs to be slightly withdrawn into the through channel 11, so that the tedious operation of cleaning the laparoscope is greatly omitted, the convenience of the operation of a doctor is improved, the operation time is also saved, and the remarkable help is brought to the operation of the doctor.
If a liquid is used in the washing process, it is preferable to use a physiological saline solution harmless to the human body, and since the amount of the liquid is small in the washing process, the physiological saline solution after washing does not affect the human body after flowing into the human body, and can be washed out of the human body following the liquid such as blood generated in the operation.
To facilitate the injection of gas or liquid required for cleaning, in one embodiment, a self-purging channel 12 extends along the length of the puncture cannula 1. And when the laparoscope is cleaned, the laparoscope is required to be cleaned in the circumferential direction, so that one or more self-cleaning channels 12 are arranged around the circumferential direction of the puncture sleeve 1, so that all-around cleaning is realized, and the cleaning effect is ensured.
It is understood that when there are an infinite number of self-purging passages 12 along the circumferential direction of the puncture cannula 1, the self-purging passage 12 can be regarded as an annular self-purging passage 12 which is provided outside the through passage 11.
A plurality of independent self-purging channels 12 are preferably employed in this embodiment to avoid interference between the channels, and the plurality of self-purging channels 12 are equally spaced around the circumference of the puncture cannula 1. Each self-cleaning channel 12 corresponds to a certain cleaning angle, so that the laparoscope can be cleaned completely in the circumferential direction.
When the self-purging channel 12 is a separate non-annular channel, its cross-section can be rectangular, oval, or arcuate with the same curvature as the penetrating cannula 1 corresponding to a certain central angle. The shape of the self-purging channel 12 is not critical to the present application provided that purging can be achieved.
Since the self-purging channel 12 extends along the length of the puncture cannula 1, the self-purging channel 12 has a length which can be as long as the puncture cannula 1 or can be a partial length of the puncture cannula. For a length of the self-purging channel 12, one or more nozzles 13 can be provided between the self-purging channel 12 and the through channel 11. When there are a plurality of nozzle orifices 13, the nozzle orifices 13 corresponding to the same cleaning channel 12 are distributed along the length of the cleaning channel 12.
In consideration of the cleaning area of the laparoscope and the processing difficulty, it is preferable that one self-cleaning channel 12 is provided with one nozzle 13, and the nozzle 13 is arranged at the end of the self-cleaning channel 12 closest to the piercing head of the piercing cannula 1.
In one embodiment, the spout 13 is disposed obliquely and obliquely upward from the purge channel 12 to the through channel 11. After the gas or liquid required by cleaning flows in from the self-cleaning channel 12, a circular flow can be generated at the connecting bent part of the nozzle 13 and the self-cleaning channel 12 through the nozzle 13 which is inclined upwards, so that the speed of spraying the gas or liquid out of the nozzle 13 is increased, and the cleaning effect on the laparoscope is improved. Meanwhile, the nozzles 13 which are obliquely and upwards arranged can also prevent gas or liquid with a certain speed from being directly sprayed towards the human body, so that the influence on the human body is avoided, and the condition that the cleaning force is offset by mutual collision of the sprayed gas or liquid when the nozzles are horizontally arranged relatively is also avoided.
When gas or liquid required for cleaning is injected into the self-cleaning channel 12, a pressure inlet is provided in the wall of the puncture cannula 1, the pressure inlet is connected to the self-cleaning channel 12, and gas or liquid required for cleaning is injected into the self-cleaning channel 12 through the pressure inlet.
However, since the inlet port is small and difficult to operate, in one embodiment, the first inlet tube 2 is connected to the side wall of the puncture cannula 1, and the first inlet tube 2 communicates with the self-purging channel 12. Gas or liquid required for cleaning is injected into the self-cleaning channel 12 through the first inlet pipe 2.
The opening of the first inlet pipe 2 may be provided with a connection structure such as a screw or a snap, and the first inlet pipe is connected to a member for pressing a gas or a liquid required for cleaning from the outside by the screw. And the first inlet pipe 2 is provided with a first valve 5, and the first valve 5 is utilized to change the on-off of the first inlet pipe 2, thereby improving the self-cleaning convenience of the puncture outfit and preventing external dust and the like from entering the self-cleaning channel 12 when the puncture outfit does not need to be cleaned.
As shown in FIGS. 5 to 7, in response to the plurality of self-cleaning channels, the self-cleaning piercer further comprises an annular flow guide block 10 in one embodiment, the annular flow guide block 10 is provided with an annular channel 14 surrounding the outside of the through channel 11, an inlet 15 of the annular channel 14 communicates with the first inlet pipe 2, and an outlet of the annular channel 14 communicates with the self-cleaning channel 12.
Since the plurality of self-purging channels 12 are arranged circumferentially around the through channel 11, the present embodiment is provided with the annular channel 14. After the gas or liquid required for cleaning is pressed into the first inlet pipe 2, the gas or liquid firstly enters the annular channel 14 through the inlet 15 and then is distributed to each self-cleaning channel 12 through the annular channel 14, so that the gas or liquid required for cleaning can be pressed in one-to-many manner.
The annular channel 14 in this embodiment is formed by a gap between the inner wall of the annular flow guide block 10 and the outer wall of the puncture cannula 1, and the inlet 15 of the annular channel 14 is arranged at one end of the annular channel 14, i.e. the position where the inner wall of the annular flow guide block 10 is free as the inlet 15. Since the annular flow guide block 10 has no part at the bottom of the annular channel 14, that is, the bottom of the annular flow guide block 10 is against the surface of the puncture cannula 1 as the bottom surface of the annular channel 14, and the end of the self-cleaning channel 12 away from the nozzle hole penetrates through the surface of the puncture cannula 1, the outlet of the annular channel 14 is the inlet of the end of the self-cleaning channel 12 away from the nozzle hole.
The self-cleaning puncture outfit in the embodiment has the advantages that the laparoscope can be cleaned, and the self-cleaning puncture outfit also has the basic function of the puncture outfit. For example, a self-cleaning lancet further comprises a puncture cannula holder 4, which puncture cannula holder 4 is arranged at an end face of the puncture cannula 1 remote from the tip. The puncture cannula seat 4 is internally connected with a rubber air-lock valve 7, and the top of the puncture cannula seat is connected with a gland 8.
In order to meet the basic requirement that the puncture outfit needs to fill air into a human body, the side wall of the puncture cannula 1 is also connected with a second inlet pipe 3, and a second valve 6 is arranged on the second inlet pipe 3 and used for opening the second valve 6 to fill air into the human body when needed.
The annular flow guide block 10 in this embodiment extends radially outward at the wall forming the annular channel 14 to be attached to the puncture cannula holder 4, so as to avoid gas leakage entering from the second inlet tube 3, meanwhile, an extending portion of the annular flow guide block 10 is provided with an avoiding hole at a position corresponding to the hollow interior of the second inlet tube 3 as the gas inlet 9, and meanwhile, the annular flow guide block 10 is provided with an upward extending lap at the periphery of the extending portion, and the choke valve 7 is lapped on the lap. After the gas guard that enters from second inlet pipe 3 enters the hollow inside of second inlet pipe 3, the gas guard enters the upper portion of annular water conservancy diversion piece 10 by air inlet 9, and the gas turns to and gets into through passage 11 under the separation of choke valve 7 to realize aerifing to the human body.
In one embodiment, the workflow of the self-cleaning lancing device of the present application is as follows:
during the operation, when the doctor finds that the vision of the laparoscope is fuzzy and needs to be cleaned, the laparoscope is lifted to the position of the nozzle. And a second valve of the second inlet pipe is opened, and the physiological saline is injected into the second inlet pipe, moves downwards along the self-cleaning channel of the puncture sleeve and then is sprayed out through a nozzle of the self-cleaning channel, so that the lens of the laparoscope is cleaned in all directions. When the normal saline is cleaned, the residual water drops of the laparoscope lens are injected into the second injection tube continuously with a certain thrust, so that the water of the laparoscope lens is blown off, the second valve is closed after the water drops are blown off, and the laparoscope is lowered to the position before cleaning to continue the operation.
It should be noted that, the above optimized workflow provided for the present embodiment, in other embodiments, the workflow of the self-cleaning puncture device based on the present embodiment may be changed, for example, only water washing with saline is performed, or only air blowing defogging is performed based on air, and the like, all of which belong to the protection scope of the present application.
